Definitions

  • the present invention relates to a method of making and affixing a reusable probe to a patient by means of disposable bandage apparatus so that there is no contact between the costly, reusable portion of the probe and the patient.
  • the contaminated bandage apparatus which is relatively inexpensive, can then be discarded after single patient use and the probe can be re-used with a new bandage apparatus.
  • pulse oximeter probes have been limited to the use of a costly, reusable probe, which is contaminated by use on a patient, or cheaper, single-use probes, which, in the aggregate, amount to a considerable expenditure for a healthcare institution.
  • One embodiment of the present invention is directed to improving the form and affixation method of a reusable pulse oximeter sensor. It comprises a reusable pulse oximeter probe with at least one light emitting diode and one photocell detector wherein said emitter and detector are enclosed in plastic housings, one housing having an aperture or radiation transparent window aligned with said emitter, and the other housing having an aperture or radiation transparent window aligned with said detector. Also included is a disposable bandage apparatus which is at least one bandage strip having adhesive on at least a portion of at least one face thereof and at least two plastic receptacles mounted thereon, each receptacle having at least one aperture or radiation transparent window located therein.
  • the probe housings can matedly engage said bandage receptacles and transmit and receive light through the apertures or radiation transparent windows of said mated housings and receptacles, and through the appendage of a patient.
  • the housings of the reusable pulse oximeter probe may also be made of a material selected from plastic, rubber, metal, wood, or other composite material.
  • the receptacles of the disposable bandage apparatus may also be made of a material selected from plastic, rubber, metal, wood, or other composite material. Additionally, the apertures of said receptacles are large enough to accept the tubular protrusions of the housings for the purpose of concentric location and alignment of the housings to the receptacles and the proper transmission and reception of light therethrough.
  • the bandage apparatus Sandwiched between the adhesive strip and the receptacles attached thereto, are translucent silicone windows or windows of another radiation transparent material for isolation of the reusable probe assembly from the patient.
  • the bandage apparatus may be discarded after single patient use and the reusable probe may be used again on another patient in conjunction with another bandage apparatus.
  • the receptacles of the bandage apparatus may have a concave surface on one side thereof in order to seat conformably on a human digit, or they may have a flat surface on at least one side thereof in order to attach conformably to a human foot, nose, or ear.
  • the housings and receptacles also contain “mushroom hook” type hook and loop material for the purpose of adhering and detaching said housings to and from said receptacles. Additionally, the housings and receptacles have recessed areas for adhesion of the “mushroom hook” hook and loop material.
  • the receptacle of the disposable bandage apparatus may be the mushroom hook material itself which may be attached directly to the adhesive strip for the selective engagement of the housings of the probe assembly.
  • the housings of the pulse oximeter probe may be affixed to the receptacles of the disposable bandage apparatus by means of a “ring and groove” type snap-on connector.
  • the housings of the reusable pulse oximeter probe may be affixed to the receptacles of the disposable bandage apparatus by means of a “twist and lock” type connector.
  • the housings of the pulse oximeter probe may be affixed to the receptacles of the disposable bandage apparatus by means of a “threaded flange” type of connector.
  • the light emitting diode and photocell detector of the probe assembly may be mounted in modular housings with locking levers which can engage an indentation or slot in the receptacles of the disposable bandage apparatus and securely lock the housings into proper position within the receptacles, thus allowing the transmission and reception of infrared light through the mated housings and receptacles and through the appendage of a patient.
  • the levers and indentations are reversed, and the light emitting diode and photocell detector of the probe assembly may be mounted in modular housings having indentations therein, and the receptacles of the disposable bandage apparatus may have the locking lever located on them.
  • the locking levers of the bandage receptacles lockingly engage the slots or indentations in the probe housings, thus locking them into place within the receptacles and allowing the transmission and reception of infrared light through the mated probe housings and bandage receptacles, and through the appendage of a patient.
  • the radiation transparent windows may be of hard plastic and may be mounted against the skin of a patient, thus being used to secure the receptacles on the opposite side of the bandage strip. This is accomplished by the incorporation of locking levers on the radiation transparent windows which are pushed through holes or slots in the bandage and engage holes in the receptacles mounted on the opposite side of the bandage, thus sandwiching the bandage in between.
  • a foam strip with holes in it may also be adhered to said radiation transparent windows in order for them to rest comfortably on a patient's appendage.
  • the bandage receptacles may be secured to the bandage through the use of small plastic protrusions or “heat stakes” mounted on the receptacles themselves. These protrusions can be pushed through slots in the bandage and can be melted on the other side of the bandage strip by means of an ultrasonic welding machine, thus locking the receptacles into position on the bandage strip.
  • a radiation transparent window may then be adhered to the underside of the bandage strip and the heat stakes and radiation transparent windows may then be overlaid with a foam pad with holes in it, the purpose of which is to allow for the transmission and reception of infrared light through the holes while aiding in patient comfort.
  • one object is to provide a method of facilitating the intra-departmental or inter-institutional transport of a patient or patients requiring the pulse oximeter monitoring, and wherein said pulse oximeters used for monitoring said patient may be of different manufacturers.
  • the method comprises affixing to said patient a bandage apparatus having a modular emitter and detector receptacles incorporated thereon, providing each said different manufacturers' pulse oximeter probe with modular housings adapted to matedly engage and/or disengage with receptacles of the disposable bandage apparatus, thus enabling said patient to be monitored by pulse oximeters of different manufacturers without changing the affixed bandage apparatus.
  • intra-departmental or inter-institutional transport is greatly facilitated by having a bandage device which will accept probes of various manufacturers, as long as those probes contain housings that will matedly engage the receptacles of the disposable bandage apparatus.
  • Another embodiment of the present invention relates to a method of making and affixing a reusable finger probe to a patient by means of a finger clip apparatus with a disposable liner insert so that there is no contact between the costly, reusable portion of the probe and the patient.
  • the contaminated liner which is relatively inexpensive, can then be discarded after single patient use and the probe and finger clip can be re-used with a new liner.
  • such disposable inserts may be provided of different sizes and would greatly enhance the fit and function of the finger clip on the patient. This is important for several reasons. Firstly, a fitted finger clip would be much more comfortable to wear than conventional finger clips.
  • a fitted finger clip would allow the transmission and reception of infrared light from the LEDs of the probe without interference from extraneous light sources around the front and edges of the finger, and thirdly, a fitted finger clip would evenly distribute the pressure from the spring of the finger clip and would be much less likely to restrict blood flow to the digit and thereby cause erroneous oxygen saturation readings.
  • Another embodiment of the present invention comprises a method for improving the reusability, fit, and cleanliness of a reusable pulse oximeter finger sensor. It comprises a reusable pulse oximeter probe with at least one light emitting diode and one photocell detector wherein said emitter and detector are mounted in respective finger clip housing arms having apertures therein, one housing arm having an aperture aligned with said emitter, and the other housing arm having an aperture aligned with said detector. Incorporated into each opposing side of the finger clip is a T-shaped channel or slot with a locking protrusion or detent at the entrance of each of the channels.
  • a disposable foam liner which is an initially, substantially planar, foam strip, having plastic backing on at least a part thereof and two T-shaped protrusions mounted in the lateral plane of said plastic backing. At opposing ends of the foam strip, and incorporated into the T-shaped protrusions, are notched levers for locking the foam strip into position in the T-shaped channel of the finger clip.
  • the plastic backing is of a thickness that will allow it to bend into a “U” shape for insertion into the finger clip.
  • the plastic backing may be entirely absent and the inherent flexibility of the foam itself will allow it to bend into the desired shape.
  • the foam strip contains two apertures located centrally therein containing silicone windows, or windows of another radiation transparent material, that will allow for the transmission and reception of infrared light. Additionally, the foam may also contain an adhesive for helping to adhere the finger clip to the patient.
  • the finger clip may be of scaled down design and would allow for the insertion of different sizes of molded foam that would conform in size to the digit on which the finger clip is to be used.
  • the foam itself would be intended to substantially envelop the finger and the finger clip would be a mechanism for pinching or biasing the two foam halves together.
  • TheOne embodiment of the present invention is directed to a system and a method of standardization of a pulse oximeter probe wherein the probe comprises at least one light emitting diode and at least one photocell detector wherein said emitter and detector are incorporated into modular plastic housings, at least one housing having an aperture or radiation transparent window aligned with said emitter, and at least said second housing having an aperture or radiation transparent window aligned with said detector; wherein said housings can lockingly engage and disengage receptacles mounted on at least either:
  • the receptacles of the disposable bandage apparatus or the reusable finger attachment device may have locking levers for lockingly engaging and disengaging the modular probe housings.
  • the probe housings may have indentations or detentes for lockingly engaging and disengaging the levers of the receptacles of the disposable bandage apparatus or reusable finger attachment device.
  • the disposable bandage apparatus may have radiation transparent windows for the isolation of the probe housings from the patient.
  • the probe housings may be standardized in size so that probes to fit at least one of a multiplicity of manufacturers' oximeters will incorporate housings that can be matedly engaged with either a reusable finger attachment device or a disposable bandage apparatus.
  • what is disclosed is thea method of supplying pulse oximeter probes compatible with at least one of a multiplicity of manufacturers' oximeters, said probe or probes incorporating standardized probe housings, which can be matedly engaged with at least either a reusable finger attachment device or a disposable bandage apparatus.

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method of making and affixing a reusable probe to a patient by means of disposable bandage apparatus so that there is no contact between the costly, reusable portion of the probe and the patient. The contaminated bandage apparatus, which is relatively inexpensive, can then be discarded after single patient use and the probe can be re-used with a new bandage apparatus.
2. Description of the Related Art
Heretofore the use of pulse oximeter probes has been limited to the use of a costly, reusable probe, which is contaminated by use on a patient, or cheaper, single-use probes, which, in the aggregate, amount to a considerable expenditure for a healthcare institution.
Others have attempted to convert single-use probes into multi-use probes through a lamination process. In that process, the original adhesive material is removed from the original manufacturer's sensor. The sensor is then laminated in a plastic sheath and the entire sheath is then inserted into a transparent, adhesive-backed sleeve, which is then adhered to a patient. After use, the probe can then be extracted from the sleeve and inserted into a new sleeve for use on another patient.
There are certain disadvantages to this method. Firstly, it is difficult to insert the flexible laminated sensor into a long sleeve. Secondly, the thickness of a laminated sensor inside of a sleeve makes it difficult to bend around, and to stick properly to, a human appendage. Thirdly, transmission and reception of infrared light can be affected by extraneous light entering from the sides of the sleeve. And, fourthly, there is some dispute as to the affect on infrared light transmission when passing through the sleeve and the adhesive material coupled thereto.
One of the problems with pulse oximetry, and the continuity of monitoring a patient, is the vast array of different monitors used in different hospital departments. Many times a patient will start out in the emergency room (ER) where the hospital utilizes one particular brand of monitor. If a disposable probe is affixed to the patient, and the patient is then admitted to intensive care, the disposable probe that was affixed in the ER will only work if the pulse oximeter used in intensive care is of the same make as the one in the ER. If that same patient is once again taken to radiology, or to have an MRI done, once again these different departments may have different pulse oximeter monitors. What happens many times is that the disposable probes affixed in one department are thrown away and new ones are affixed in other departments. Obviously, this creates additional expense in providing pulse oximetry monitoring.
SUMMARY OF THE INVENTION
The current applicant, in his U.S. Pat. No. 6,144,868, and subsequent continuations-in-part, has described a reusable pulse oximeter probe to be used with a disposable bandage apparatus. With this device, the costly reusable portion of the probe is isolated from the patient by means of an inexpensive bandage apparatus. This allows the caregiver to dispose of the inexpensive bandage apparatus while retaining the more costly, reusable portion of the probe. The reusable probe can then be used in conjunction with another disposable bandage apparatus on another patient.
One embodiment of the present invention is directed to improving the form and affixation method of a reusable pulse oximeter sensor. It comprises a reusable pulse oximeter probe with at least one light emitting diode and one photocell detector wherein said emitter and detector are enclosed in plastic housings, one housing having an aperture or radiation transparent window aligned with said emitter, and the other housing having an aperture or radiation transparent window aligned with said detector. Also included is a disposable bandage apparatus which is at least one bandage strip having adhesive on at least a portion of at least one face thereof and at least two plastic receptacles mounted thereon, each receptacle having at least one aperture or radiation transparent window located therein. The probe housings can matedly engage said bandage receptacles and transmit and receive light through the apertures or radiation transparent windows of said mated housings and receptacles, and through the appendage of a patient. The housings of the reusable pulse oximeter probe may also be made of a material selected from plastic, rubber, metal, wood, or other composite material. The receptacles of the disposable bandage apparatus may also be made of a material selected from plastic, rubber, metal, wood, or other composite material. Additionally, the apertures of said receptacles are large enough to accept the tubular protrusions of the housings for the purpose of concentric location and alignment of the housings to the receptacles and the proper transmission and reception of light therethrough. Sandwiched between the adhesive strip and the receptacles attached thereto, are translucent silicone windows or windows of another radiation transparent material for isolation of the reusable probe assembly from the patient. The bandage apparatus may be discarded after single patient use and the reusable probe may be used again on another patient in conjunction with another bandage apparatus. Additionally, the receptacles of the bandage apparatus may have a concave surface on one side thereof in order to seat conformably on a human digit, or they may have a flat surface on at least one side thereof in order to attach conformably to a human foot, nose, or ear. The housings and receptacles also contain “mushroom hook” type hook and loop material for the purpose of adhering and detaching said housings to and from said receptacles. Additionally, the housings and receptacles have recessed areas for adhesion of the “mushroom hook” hook and loop material.
In another embodiment of the invention, the receptacle of the disposable bandage apparatus may be the mushroom hook material itself which may be attached directly to the adhesive strip for the selective engagement of the housings of the probe assembly.
In another embodiment of the invention, the housings of the pulse oximeter probe may be affixed to the receptacles of the disposable bandage apparatus by means of a “ring and groove” type snap-on connector.
In yet another embodiment of the invention, the housings of the reusable pulse oximeter probe may be affixed to the receptacles of the disposable bandage apparatus by means of a “twist and lock” type connector.
In a further embodiment of the invention, the housings of the pulse oximeter probe may be affixed to the receptacles of the disposable bandage apparatus by means of a “threaded flange” type of connector.
In a preferred embodiment of the invention, the light emitting diode and photocell detector of the probe assembly may be mounted in modular housings with locking levers which can engage an indentation or slot in the receptacles of the disposable bandage apparatus and securely lock the housings into proper position within the receptacles, thus allowing the transmission and reception of infrared light through the mated housings and receptacles and through the appendage of a patient.
In another variation of this preferred embodiment of the invention, the levers and indentations are reversed, and the light emitting diode and photocell detector of the probe assembly may be mounted in modular housings having indentations therein, and the receptacles of the disposable bandage apparatus may have the locking lever located on them. In such an embodiment, the locking levers of the bandage receptacles lockingly engage the slots or indentations in the probe housings, thus locking them into place within the receptacles and allowing the transmission and reception of infrared light through the mated probe housings and bandage receptacles, and through the appendage of a patient.
In these modular housing and receptacle embodiments, the radiation transparent windows may be of hard plastic and may be mounted against the skin of a patient, thus being used to secure the receptacles on the opposite side of the bandage strip. This is accomplished by the incorporation of locking levers on the radiation transparent windows which are pushed through holes or slots in the bandage and engage holes in the receptacles mounted on the opposite side of the bandage, thus sandwiching the bandage in between. A foam strip with holes in it may also be adhered to said radiation transparent windows in order for them to rest comfortably on a patient's appendage.
In another variation of the above, the bandage receptacles may be secured to the bandage through the use of small plastic protrusions or “heat stakes” mounted on the receptacles themselves. These protrusions can be pushed through slots in the bandage and can be melted on the other side of the bandage strip by means of an ultrasonic welding machine, thus locking the receptacles into position on the bandage strip. In this embodiment a radiation transparent window may then be adhered to the underside of the bandage strip and the heat stakes and radiation transparent windows may then be overlaid with a foam pad with holes in it, the purpose of which is to allow for the transmission and reception of infrared light through the holes while aiding in patient comfort.
In some embodiments, one object is to provide a method of facilitating the intra-departmental or inter-institutional transport of a patient or patients requiring the pulse oximeter monitoring, and wherein said pulse oximeters used for monitoring said patient may be of different manufacturers. The method comprises affixing to said patient a bandage apparatus having a modular emitter and detector receptacles incorporated thereon, providing each said different manufacturers' pulse oximeter probe with modular housings adapted to matedly engage and/or disengage with receptacles of the disposable bandage apparatus, thus enabling said patient to be monitored by pulse oximeters of different manufacturers without changing the affixed bandage apparatus.
With some embodiments of the present invention, intra-departmental or inter-institutional transport is greatly facilitated by having a bandage device which will accept probes of various manufacturers, as long as those probes contain housings that will matedly engage the receptacles of the disposable bandage apparatus.
Another embodiment of the present invention relates to a method of making and affixing a reusable finger probe to a patient by means of a finger clip apparatus with a disposable liner insert so that there is no contact between the costly, reusable portion of the probe and the patient. The contaminated liner, which is relatively inexpensive, can then be discarded after single patient use and the probe and finger clip can be re-used with a new liner. Additionally, such disposable inserts may be provided of different sizes and would greatly enhance the fit and function of the finger clip on the patient. This is important for several reasons. Firstly, a fitted finger clip would be much more comfortable to wear than conventional finger clips. Secondly, a fitted finger clip would allow the transmission and reception of infrared light from the LEDs of the probe without interference from extraneous light sources around the front and edges of the finger, and thirdly, a fitted finger clip would evenly distribute the pressure from the spring of the finger clip and would be much less likely to restrict blood flow to the digit and thereby cause erroneous oxygen saturation readings.
Another embodiment of the present invention comprises a method for improving the reusability, fit, and cleanliness of a reusable pulse oximeter finger sensor. It comprises a reusable pulse oximeter probe with at least one light emitting diode and one photocell detector wherein said emitter and detector are mounted in respective finger clip housing arms having apertures therein, one housing arm having an aperture aligned with said emitter, and the other housing arm having an aperture aligned with said detector. Incorporated into each opposing side of the finger clip is a T-shaped channel or slot with a locking protrusion or detent at the entrance of each of the channels. Also included is a disposable foam liner which is an initially, substantially planar, foam strip, having plastic backing on at least a part thereof and two T-shaped protrusions mounted in the lateral plane of said plastic backing. At opposing ends of the foam strip, and incorporated into the T-shaped protrusions, are notched levers for locking the foam strip into position in the T-shaped channel of the finger clip. In the center of the foam strip, the plastic backing is of a thickness that will allow it to bend into a “U” shape for insertion into the finger clip. Alternatively, the plastic backing may be entirely absent and the inherent flexibility of the foam itself will allow it to bend into the desired shape. Additionally, the foam strip contains two apertures located centrally therein containing silicone windows, or windows of another radiation transparent material, that will allow for the transmission and reception of infrared light. Additionally, the foam may also contain an adhesive for helping to adhere the finger clip to the patient.
In another preferred embodiment of the invention, the finger clip may be of scaled down design and would allow for the insertion of different sizes of molded foam that would conform in size to the digit on which the finger clip is to be used. In such an application, the foam itself would be intended to substantially envelop the finger and the finger clip would be a mechanism for pinching or biasing the two foam halves together.
Despite the cost and safety advantages of the reusable probe and disposable bandage apparatus over disposable probes, an increasing number of institutions are beginning to utilize reusable finger clip probes because of the cost savings associated with a completely reusable product. Despite the discomfort of these devices and the risk of spreading infection from patient to patient, the trend toward reusable probes continues to strengthen.
However, in all institutions there is always the need for some disposable probes. Patients who have compromised immune systems, surgical patients, where sterility is important, and neonatal and pediatric patients, where the size of the appendage to be monitored is too small for finger clips, require the use of disposable probes or a disposable bandage apparatus.
Clearly, it would be advantageous to offer a universal, modular, reusable probe that could be used in conjunction with either a reusable finger attachment device or a disposable bandage apparatus, each having receptacles into which the reusable probe could be lockingly engaged and disengaged. In addition, probes from all the different oximeter manufacturers could be standardized so that they could be used in conjunction with these same patient attachment devices.
THE PRESENT INVENTION
TheOne embodiment of the present invention is directed to a system and a method of standardization of a pulse oximeter probe wherein the probe comprises at least one light emitting diode and at least one photocell detector wherein said emitter and detector are incorporated into modular plastic housings, at least one housing having an aperture or radiation transparent window aligned with said emitter, and at least said second housing having an aperture or radiation transparent window aligned with said detector; wherein said housings can lockingly engage and disengage receptacles mounted on at least either:
    • (a) a reusable finger attachment device, or
    • (b) a disposable bandage apparatus,
      and transmit and receive light through the appendage of a patient when either of the above devices are attached to a patient and when the housings of said probe are matedly engaged with the receptacles of the attached device.
The receptacles of the disposable bandage apparatus or the reusable finger attachment device may have locking levers for lockingly engaging and disengaging the modular probe housings.
The probe housings may have indentations or detentes for lockingly engaging and disengaging the levers of the receptacles of the disposable bandage apparatus or reusable finger attachment device.
The disposable bandage apparatus may have radiation transparent windows for the isolation of the probe housings from the patient.
The probe housings may be standardized in size so that probes to fit at least one of a multiplicity of manufacturers' oximeters will incorporate housings that can be matedly engaged with either a reusable finger attachment device or a disposable bandage apparatus.
WhatAccording to one embodiment, what is disclosed is thea method of supplying pulse oximeter probes compatible with at least one of a multiplicity of manufacturers' oximeters, said probe or probes incorporating standardized probe housings, which can be matedly engaged with at least either a reusable finger attachment device or a disposable bandage apparatus.

Reusable Pulse Oximeter Probe and Disposable Bandage Apparatuses and Methods
Description of a Reusable Pulse Oximeter Sensor
The reusable pulse oximeter sensor constitutes a “Y” style pulse oximeter probe shown in FIG. 1, Item F. The probe incorporates two plastic housings shown as FIG. 1, Items G. The housings contain apertures or radiation transparent windows L therein. One housing contains the light-emitting diode of the probe, FIG. 1, Item H, and other contains the photocell detector, FIG. 1, Item I. The emitter and detectors are aligned with the apertures or windows L of the housings in order to transmit and receive light through a human appendage.
Seated within a recessed area of each housing, and attached permanently thereto, is a “mushroom hook” adhesive-backed pad, FIG. 1, Item K. The purpose of these pads is to selectively engage the “mushroom hook” pads, FIG. 1, Items J, attached permanently to the plastic discs, FIG. 1, Items D, and to attach the reusable probe assembly to the Disposable Bandage Apparatus. The reusable pulse oximeter sensor is shown assembled as FIG. 2, Item A.
In one preferred embodiment of the reusable pulse oximeter sensor, the light-emitting diode (FIG. 5, Item A) and photocell detector (FIG. 5, Item B) of the probe assembly are housed in modular receptacles (FIG. 5, Items C) having locking levers (FIG. 5, Items D) for engaging the receptacles of the disposable bandage apparatus, and locking them into place.

In the one preferred embodiment of the Reusable Pulse Oximeter Sensor, the light emitting diode (FIG. 14, Item A) and photocell detector (FIG. 14, Item B) of the probe assembly are housed in modular receptacles (FIG. 14, Items C) having locking levers, (FIG. 14, Items D) for engaging the receptacles (FIG. 15, Items A) of the disposable bandage apparatus, and locking them into place.
In the another preferred embodiment of the Reusable Pulse Oximeter Sensor, the light emitting diode (FIG. 17, Item A) and the photocell detector (FIG. 17, Item B) are encased in modular housings having a radiation transparent bottom (FIG. 17, Items C) and having opaque housing tops (FIG. 17, Items D). These housing tops and bottoms are ultrasonically welded together thus encapsulating the light emitting diode and photocell detector of the probe assembly. The housing tops incorporate indentations or slots (FIG. 17, Items E) designed to matedly engage a protrusion on the locking levers of the bandage receptacles thus snapping into place and securing the probe housings within the bandage receptacles.
According to one embodiment of the present invention, intra-departmental or inter-institutional transport is greatly facilitated by having a bandage device which will accept probes of various manufacturers, as long as those probes contain housings that will matedly engage the receptacles of the disposable bandage apparatus.
Description of a Disposable Bandage Apparatus
The components of the apparatus include an adhesive-backed strip, shown as FIG. 1, Item A, the strip A incorporating two oval protrusions B centered thereon and shown as FIG. 1. The strip also incorporates two apertures, centrally located within the oval protrusions, each aperture C having a diameter sufficient in size to accommodate the transmission and reception of light from a light-emitting diode and photocell detector of a pulse oximeter probe.
On top of the apertures C are seated two plastic discs, FIG. 1, Item D, each having a concave base designed to conform to the radius of a human digit, and an aperture of slightly larger diameter than the apertures in the adhesive backed planar strip. The plastic discs are affixed to the adhesive planar strip by means of a permanent adhesive.
Seated in a recessed area on top of each plastic disc is a “mushroom hook”, adhesive backed pad shown as FIG. 1, Item J. The purpose of the “mushroom hook” pads is to selectively engage the “mushroom hook” pads attached to the probe, FIG. 1, Items K, and to attach the probe to the disposable bandage apparatus. Sandwiched between the two plastic discs and the planar adhesive strip are two translucent silicone windows, FIG. 1, Item E. The windows are designed to permit the passage of infrared light and yet prevent contact between probe and patient, and consequently, contamination of the reusable probe itself.
The above items constitute the disposable bandage apparatus according to one embodiment of the invention, the apparatus being shown assembled as FIG. 2, Item B.
In another embodiment of the invention, the disposable bandage apparatus may be configured as in FIG. 4 of the drawings. FIG. 4 is an exploded view of the apparatus in which the “mushroom hook” pads of the bandage apparatus, FIG. 4, Items J, are bonded directly to the adhesive planar strip, FIG. 4, Item A, for the selective engagement of the “mushroom hook” pads of the probe, FIG. 4, Items K, the pads being attached permanently to the housings of the probe, FIG. 4, Items G.
In one preferred embodiment of the disposable bandage apparatus, the bandage strip (FIG. 7, Item A) is sandwiched between interlocking receptacle halves. The top halves of the receptacles (FIG. 7, Items B) contain locking levers (FIG. 7, Items C) that are pushed through slots cut in the bandage strip (FIG. 7, Items D) and lockingly engage indentations (FIG. 7, Items E) in the bottom halves of the receptacles (FIG. 7, Items F), thus sandwiching and locking the bandage in between. The bandage strip contains two apertures (FIG. 7, Items G) for the transmission and reception of light from the light-emitting diode and photocell detector of the pulse oximeter sensor which are encased in modular housings having locking levers (FIG. 5, Items D) wherein the levers engage slots in the receptacles (FIG. 7, Items H) thereby locking the housings into place within the receptacles. In addition, the bottom halves of the receptacles (FIG. 7, Items F) are of a radiation transparent material, thus allowing the light-emitting diode and photocell detector contained in the probe housings, when engaged in the bandage receptacles, to transmit and receive light through the apertures of the bandage strip and through the radiation transparent material of the bottom halves of the receptacles, and through the appendage of a patient. The complete reusable pulse oximeter probe and bandage assembly is shown assembled and ready for use on a human digit in FIG. 8.
In other embodiments of the disposable bandage apparatus, the bandage may have mounted thereon receptacles having means of matedly engaging the housings of the reusable pulse oximeter sensor by way of “ring and groove”snap-on type connectors (FIG. 11, Items B); “Twist and Lock” type connectors (FIG. 12, Items B); or “threaded flange” type connectors (FIG. 13, Items C).
In one preferred embodiment of the Disposable Bandage Apparatus, the bandage strip (FIG. 15, Item B) is sandwiched between interlocking receptacle halves. The top halves of the receptacles (FIG. 15, Items A) each contain 4 holes (FIG. 15, Items C) that are designed to matingly engage locking tabs (FIG. 15, Items D) on the bottom half of the receptacles (FIG. 15, Items E) that are pushed through slots cut in the bandage strip (FIG. 15, Items F) thus securing and locking the bandage in between.
The bandage strip contains two apertures or radiation transparent windows (FIG. 15, Items G) allowing for the transmission and reception of light from the light emitting diode and photocell detector of the pulse oximeter sensor which are encased in modular housings having locking levers (FIG. 14, Items D) wherein said levers engage slots in the receptacles (FIG. 15, Items H) thereby locking the housings into place within the receptacles. In addition, the bottom halves of the receptacles (FIG. 15, Items E) can be of a radiation transparent material, or may contain apertures (FIG. 15, Items I) thus allowing the light emitting diode and photocell detector contained in the probe housings, when engaged in the bandage receptacles, to transmit and receive light through the apertures of the bandage strip and through the radiation transparent material, or apertures, of the bottom halves of the receptacles, and through the appendage of a patient. The disposable bandage apparatus may also incorporate a foam strip (FIG. 15, Item J) in order to cushion a patient's appendage from any discomfort caused by the bottom half of the bandage receptacles. The complete Reusable Pulse Oximeter Sensor, engaged in the disposable Bandage Apparatus, and ready for use on a human appendage, is shown in FIG. 16.
In another preferred embodiment of the disposable bandage apparatus, the bandage receptacles (FIG. 17, Items G) are secured to the bandage (FIG. 17, Item K) by means of four protrusions or “heat stakes” (FIG. 17, Items H) which are pushed through slots (FIG. 17, Items J) on the bandage (FIG. 17, Item K) and are ultrasonically welded on the other side, thus securing the receptacles to the bandage. A radiation transparent window (FIG. 17, Item M) is then adhered to the underside of the bandage and the radiation transparent windows and melted heat stakes are then overlaid by a foam pad (FIG. 17, Item L) to aid in patient comfort. This foam pad also incorporates two holes which are in alignment with the two holes on the bandage itself, and when the foam pad is overlaid on the underside of the bandage, the radiation transparent windows are sandwiched in between.
The probe housings are designed to matedly engage the bandage receptacles (FIG. 17, Items G) and are held in place within the receptacles by means of protrusions (FIG. 17, Items F) on the locking levers (FIG. 17, Items I) which snap into place when the probe housings are pushed into the bandage receptacles. When the probe housings are locked into place within the bandage receptacles the light emitting diode and photocell detector are in alignment with the holes in the bandage and the foam overlay, and the probe is then able to transmit and receive light through the mated housings and receptacles, through the holes contained in the bandage and foam overlay, and through the appendage of a patient. The complete assembled Reusable Pulse Oximeter Sensor engaged within the Disposable Bandage Apparatus, as it would appear ready for use on a patient, is shown in FIG. 18.
Other Fastening Means
As can be appreciated, there are many ways of fabricating the above components of the invention. The above description describes attachment of the reusable pulse oximeter sensor to the disposable bandage apparatus by way of a “mushroom hook” type hook and loop material and by the use of telephone type modular connectors and receptacles. In addition to this means, a number of other methods may be used including standard hook and loop material, “ring and groove” type snap-on connectors, “push and twist” type Luerlock connectors, and threaded flange type connectors. While these means are fairly comprehensive, they should in no way be considered exhaustive.
Method of Use
According to one method for use on an individual patient, the probe is affixed in the following manner:
Firstly, the backing is removed from the adhesive strip of the disposable bandage apparatus. One of the apertures of the apparatus is visually positioned on the center of the nail bed of the patient's appendage and one side of the adhesive strip and the oval protrusions are adhered to the patient's digit. The rest of the strip is then looped over the end of the patient's appendage, and the plastic disc is aligned so as to exactly oppose the plastic disc already attached to the other side of the digit. Once the disposable bandage apparatus has been properly adhered to the patient, the plastic housings of the probe assembly can be easily snapped into place on opposing sides of the digit. The entire assembled probe is shown as it would appear in use on a patient in FIG. 3.
According to one method for use with the “ring and groove” type snap-on connectors, “twist and lock”, and “threaded flange” connectors, the backing is firstly removed from the adhesive strip. The strip is then folded in half where indicated on the bandage and the bandage apparatus is adhered to either side of the human digit. Once the bandage apparatus is in place the probe housings are simply snapped, twisted or screwed into place.
According to one method for use with a patient, the modular probe and bandage assembly, which is one preferred embodiment of the invention, would be attached as follows:
Firstly, the backing is removed from the adhesive strip. The strip is then folded where indicated on the bandage and the strip is then adhered to opposing sides of the human digit. Once the bandage apparatus is in place, the housings of the probe are pushed into the receptacles and locked in place by means of the locking levers. When the patient is moved between different service areas of a hospital, the probes can be removed and the patient transported to a new service area where that area's oximeter probes are pushed into the receptacles for further oximeter readings.
As shown in FIG. 9, one embodiment of the invention is easily adaptable to different manufacturers' oximeters being used in different departments or institutions when the patient is to be transported between the departments or institutions. As shown in FIG. 9, at the admissions area AD, when the patient is admitted to the hospital or facility, an oximeter bandage is initially applied. Then the patient may go through another testing area or department D1 where various serological, pathological tests may be run. Then the patient is shown as being transported to a radiology area such as where X-ray and magnetic resonance images (MRI) scans are made. Other departments may have the patient transported thereto such as a surgery department DS and a recovery room RR and the patient's room PR where, in each instance, a different manufacturer or different oximeter probes may be attached where, according to the invention, the receptacles on the bandages are able to receive and retain housings on the emitter and detector elements of the probe.
An example of the flexibility of the system of this invention is illustrated in FIG. 10. In this pictorial embodiment, a magnetic resonance image system or an MRI machine is shown as being positioned in one room with the patient and having applicant's disposable bandage apparatus attached to the finger of a patient. In this case, the patient is in the MRI facility where the patient is just having MRI work done. The probe housings are shown attached at the ends of fiberoptic cable connected to a connector which has the light-emitting diode and the light detector incorporated therein with a connector or plug for plugging into a pulse oximeter PO. The light-emitting and light-receiving ends of the fiberoptic cable are directed or oriented in the modular housings to emit IR light into the finger and receive IR light transmitted through the finger. It will be noted that since in the MRI application no ferrous materials are allowed, the LED's are placed in a room many feet away (up to fifty or more feet away) and (the oximeter device is in optical communication with the applicant's bandage apparatus. Thus, in situations where non-ferrous materials are required, the probe has non-ferrous housings and materials designed to matedly engage with the receptacles of applicant's disposable bandage apparatus. The housings of the probe are in fiberoptic communication with the LED's which would be at the other end of the probe near the pulse oximeter.
As shown above, in case of magnetic resonance imaging (MRI) situations where the presence of any metal in the environment can effect the MRI readings, the probe and emitter elements are situated remotely from the MRI machine and fiberoptic cable conveys light to and from the patient's finger. In this case, the oximeter probe housings are the termination ends of the fiberoptic cable and the modular housings are therefore able to be inserted into the bandage receptacles and the oximeter readings taken in this fashion from a remote area.
In some embodiments of the invention, when the probe is no longer required on the patient, the housings of the reusable probe are simply unsnapped from the disposable bandage apparatus, the bandage apparatus is thrown away, and the probe can then be reused on a new patient in conjunction with a new bandage apparatus.
Advantages of Some Embodiments
Current reusable pulse oximeter probes are either “clam shell” type clamping devices which can restrict circuit or “Y” type probes which are taped directly to the patient. Both types also come in direct contact with the patient's skin and bodily fluids and need sterilization after use. Because of the fact that these devices incorporate many surfaces and at times, porous materials, proper sterilization is very difficult. With some embodiments of the present invention there is no contact between the reusable probe and the skin or bodily fluids of the patient.
Disposable probes are very costly because of the fact that the cable, connectors and photodiodes are all disposed of after use. Some embodiments of the present invention accomplishe the same goals as a disposable probe from a cleanliness standpoint, but since only the attachment apparatus is discarded after use, the cost is much less to a healthcare institution.
One embodiment of the present invention, with the concave shape of the plastic discs of the bandage apparatus, when backed by the adhesive strip, is extremely effective in preventing the entrance of extraneous light from the sides of the patient s digit. Current probes on the market, whether disposable or reusable, because of the nature of their shape and affixation means, have problems in dealing with extraneous light reception.
One embodiment of the present invention utilizes an easy snap-on, snap-off, or modular connector attachment means for attaching the probe to the disposable bandage apparatus. Probe-shield type devices available in the past not only required the modification of the original manufacturer's probe, but required the difficult procedure of inserting a flexible laminated probe into a sheath for each patient.
Probe-shield devices, because of the lamination process involved, raised some concern over the transmission and reception of infrared light through the laminating material. One embodiment of the present invention uses a silicone window for the isolation of the probe from the patient. Infrared light transmission and reception is not affected by passage through translucent silicone.
In these days of environmental consciousness, the annual waste generated from tens of millions of disposable probes is enormous. Some embodiments of the present invention, if used in considerable numbers, would greatly reduce the amount of environmental waste generated by disposable pulse oximeter probes.
In some embodiments, intra-departmental or inter-institutional transport is greatly facilitated by having a bandage device which will accept probes of various manufacturers, as long as those probes contain housings that will matedly engage the receptacles of the disposable bandage apparatus.

In the event that a Disposable Bandage Apparatus is in use, it is then thrown away after the probe has been removed. When a Reusable Finger Attachment Device is in use, it may be removed, washed, and reused on another patient.
ADVANTAGES OF THE PRESENT INVENTION
Advantages of Some Embodiments
1. The standardization of probes within a hospital whereby a multiplicity of manufacturers' oximeters could utilize probes having housings of the same size for engaging either reusable or disposable attachment devices is very favorable.
2. Finger attachment devices on the market today are hard wired to the probes, and when breakage occurs on the finger clip, the entire probe must be repaired or thrown away. With some embodiments of the present invention, when breakage occurs in either the finger attachment device or the probe itself, only the broken component has to be replaced.
3. A big problem exists with maintaining the cleanliness of reusable finger clips because the electronics are not removable from the finger clip and the device cannot be immersed or cleaned. With some embodiments of the present invention, the Reusable Finger Attachment Device can be removed from the probe and cleaned or sterilized.
While the invention has been described in relation to preferred embodiments of the invention, it will be appreciated that other embodiments, adaptations and modifications of the invention will be apparent to those skilled in the art.
