Description

MEDICAL SENSOR WITH FLEXIBLE COMPONENTS AND
TECHNIQUE FOR USING THE SAME
BACKGROUND

The present disclosure relates generally to medical devices and, more particularly, to sensors used for sensing physiological parameters of a patient.

This section is intended to introduce the reader to aspects of the art that may be related to various aspects of the present disclosure, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

In the field of medicine, doctors often desire to monitor certain physiological characteristics of their patients. Accordingly, a wide variety of devices have been developed for monitoring many such physiological characteristics. Such devices provide doctors and other healthcare personnel with the information they need to provide the best possible healthcare for their patients.
As a result, such monitoring devices have become an indispensable part of modern medicine.

One technique for monitoring certain physiological characteristics of a patient is commonly referred to as pulse oximetry, and the devices built based upon pulse oximetty techniques are commonly referred to as pulse oximeters. Pulse oximetry may be used to measure various blood flow characteristics, such as the blood-oxygen saturation of hemoglobin in arterial blood, the volume of individual blood pulsations supplying the tissue, and/or the rate of blood pulsations corresponding to each heartbeat of a patient. In fact, the "pulse" in pulse oximetry refers to the time varying amount of arterial blood in the tissue during each cardiac cycle.

Pulse oximeters typically utilize a non-invasive sensor that transmits light through a patient's tissue and that photoelectrically detects the absorption and/or scattering of the transmitted light in such tissue. One or more of the above physiological characteristics may then be calculated based upon the amount of light absorbed or scattered. More specifically, the light passed through the tissue is typically selected to be of one or more wavelengths that may be absorbed or scattered by the blood in an amount correlative to the amount of the blood constituent present in the blood. The amount of light absorbed and/or scattered may then be used to estimate the amount of blood constituent in the tissue using various algorithms.

Pulse oximetry readings involve placement of a sensor on a patient's tissue, typically via a lightly adhesive sensor, a clip-style sensor, or a sensor that may be fitted into a wearable garment, such as a hat or a headband. With regard to the latter, if the hat or headband is not closely fitted to the patient's tissue, ambient light may interfere with the sensor's light detection. Some outside light infiltration into the sensor may be avoided by fitting the sensor snugly against the patient's tissue. However, such a conforming fit may be difficult to achieve over a range of patient physiologies without adjustment or excessive attention on the part of medical personnel. Additionally, an overly tight fit may cause local exsanguination of the tissue around the sensor. Exsanguinated tissue, which is devoid of blood, may shunt the sensor light through the tissue, which may also affect measurement accuracy.

DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS
One or more specific embodiments of the present disclosure will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
Medical sensors for applications utilizing spectrophotometry are provided therein that include optical components that conform closely to a patient's tissue.
Such sensors may include sensors for pulse oximetry, tissue water fraction, tissue carbon dioxide, hematocrit, or glucose, or any combination thereof. In an embodiment, a hat-based pulse medical sensor assembly for neonatal patients may be configured to provide a conforming fit without uncomfortable pressure on the tissue. Because the accuracy of spectrophotometric sensors, such as pulse oximetry sensors, may be improved when the sensor is directly in contact with the skin, it may be desirable to avoid stiff or inflexible electrical or optical components that may interfere with the fit of the hat.

Hence, provided herein are flexible, wearable sensing assemblies that include optical components that may be woven into the fabric of the wearable sensor or applied directly to the fabric of the without stiff backing materials. In an embodiment, such sensor assemblies may include optical fibers that are woven into a fabric of the sensor assembly to transmit light into a patient's tissue and return light that has passed through the tissue and is representative of a physiological constituent. Also provided herein are sensor assemblies that include optical component backing materials that are thin and/or highly flexible. Such thin and/or highly flexible materials may also provide the advantage of having gripping properties without being adhesive. Sensor assemblies may also include thin and flexible optical components, such as ultrathin light emitters and photodetectors. In embodiments, the sensor assemblies may include optical components that are flush or substantially flush with the sensor body. For example, a hat band may include a pocket in which the optical components may be placed so that the surface that contacts the tissue is generally smooth or planar.

In an embodiment, a medical sensor, such as a sensor for pulse oximetry, may be adapted for placement in a hat (for example, a neonatal stocking cap), a headband, or other wearable structure (i.e. a glove, a sock, a wristband) to apply the sensor on the body of the user.

FIG. 1 illustrates an embodiment of a sensor assembly 10 including a wearable structure, which may be a hat 12, as shown in FIG. 1. The optical components of the sensor may include optical fibers 16 that transmit light from a light emitter. The optical fibers are woven into the fabric of the hat 12.
When the hat 12 is applied to the patient, the optical fibers come into contact with the skin and are able to transmit and receive light as part of a medical sensor assembly 10.
As shown, the optical fibers 16 may be distributed throughout the hat, allowing for multiple sites of measurement. In embodiments, a monitor or downstream measurement device may receive signals related to multiple measurements from the sensor assembly 10 and may combine or otherwise analyze the results.

Also shown in FIG. 1 is a cable 20 for providing an electrical/optical connection for the optical fibers 16 to downstream light emitter(s) and photodetector(s) (not shown). FIG. 1 shows that the cable 20 is positioned through an opening 22 in the top 24 of the hat 12. In an embodiment, the cable 20 may be adhered or otherwise constrained in the hat 12 so that the cable generally is positioned away from the hat 12 to avoid interfering with the patient's eyesight or bothering the patient.

The optical fibers 16 may be single fibers or fiber bundles. The fibers or fiber bundles 16 may be formed from relatively flexible materials, for example a transparent plastic, such as poly(methyl methacrylate) or polystyrene with a fluoropolymer cladding. Examples of optical fibers 16 include single-mode fibers, multi-mode fibers, photonic-crystal fibers, hollow-core fibers, polarization-maintaining fibers and dual-clad fibers. Typical diameters for optical fibers may be 5 to 1,000 micrometers.

In one embodiment, an individual optical fiber 16 may serve to emit light into tissue and receive the light reflected back by the tissue. In other words, each individual fiber 16 may transmit emitted light and receive reflected light. In an embodiment, a fiber bundle may include fibers that are dedicated emitting fibers (i.e., optically connected to a light source) and dedicated detecting fibers (i.e., optically connected to a photodetector). A hat 12 may be woven from an optical fiber fabric, such as Luminex@ Fabric (Luminex S.P.A., Italy). In one particular implementation, the optical fibers 16 may be spaced apart within the hat 12 so alternating fibers 16 are dedicated emitting fibers and dedicated detecting fibers. In such an implementation, the spacing of the fibers 16 may reflect appropriate emitter-detector spacing for pulse oximetry applications, such as at least about lmrn to at least about 14mm spacing. In embodiments, the spacing may be Imm-8mm or 2mm-6mm. For other types of medical sensors, such as water fraction sensors, the spacing distance may be larger or smaller, as appropriate.

In one implementation, the optical fibers 16 may be woven into the hat.
For example, the optical fibers 16 may be woven such that generally run in the same direction, such as down the length of the hat from opening 22 towards hat band 26. The distal ends 28 of the optical fibers 16 may terminate in the band 26.
It should be understood that a hat 12 as envisioned may not necessarily include a band 26. In embodiments, the hat 12 may simply include a distal opening 27, and the optical fibers 16 may terminate near or towards the distal opening 27. The optical fibers 16 may be notched, terminated, scribed, or modified, for example by a cutter during the weaving process, at an appropriate location in the hat band 26.
At the top portion 24 of the hat 12, the proximal ends 30 of the optical fibers 16 may be gathered within cable 20 or may otherwise optically connect to an emitter and photodetector. During the weaving process, the proximal ends 30 of the optical fibers 16 may be left loose so that they may be later incorporated into the cable 20 or other optical connector.

While hat-based sensor assemblies 10 may generally be used on neonatal patients, adult patients may more typically wear forehead sensors that are applied directly to the forehead or sensors that are integrated into a headband. Hat-based sensors may be designed to apply light pressure to the head of an infant. In contrast, headband-based sensors may be designed to apply more pressure to the more robust tissue of an adult, which may facilitate a more conforming fit of the sensor and more accurate measurements. FIG. 2 illustrates an embodiment of a headband-based sensor assembly 40. The headband-based sensor assembly 40 may include a strap or band 42 that may be fitted around a patient's forehead tissue to bring the optical fibers 16 with the tissue. The optical fibers 16 may be woven into the fabric of the band 42. In one embodiment, the band 42 may include indicators to position the distal ends 44a and 44b of the optical fibers 16 on a particular location on the patient's forehead, for example to position the distal ends 44a and 44b on the lower forehead region, above the eyebrow, above and predominantly lateral to or centered over the iris, The location of the distal ends 44a and 44b within the band 42 facilitate appropriate placement of the optical sensing components in the desired forehead location by a user. In addition, the headband-based sensor assembly 40 may include one or more alignment indices 42, for example a printed design on the band 42 visible to the caregiver, to assist in the proper placement of the distal ends 44a and 44b of the optical fibers 16 on the patient's forehead.

In addition to using optical fibers 16 to deliver light to a patient's tissue, similar advantages (e.g., flexible optical components) may be realized by fabricating the optical components, without stiff backing materials. In an embodiment shown in FIG. 3, a hat assembly 58 may include sensing components, e.g., an emitter 60 and a detector 62, that may be applied directly to the fabric surface of the hat 12. The emitter 60 and the detector 62 may be adhered to the interior, tissue-contacting, surface 64 of the hat band. In addition, leads 56 and 58 connecting the emitter 60 and the detector 62 to the cable 20 may be adhered to or woven into the fabric of the hat 12. In embodiments in which additional electrical shielding may be desirable, the emitter 60 and the detector 62 may be glued or otherwise adhered onto thin wire mesh or other thin and flexible backings 66 and 68, respectively, which may in turn be adhered to the band 26 of the hat 12.
In embodiments, flexible backings 66 and 68 may be formed from any thin and flexible material, for example any flexible material less than 5mm in thickness, less than 1mm in thickness, or less than 0.5 mm in thickness. The material may be sufficiently flexible to conform easily to a patient's tissue.

In certain embodiments, the sensing components themselves may be formed from thin and/or flexible materials. For example, leads 56 and 58 may be formed from thin and flexible shielded wires. The emitter 60 may be an ultra-thin LED, such as a 0.25mm LED, available from Kingbright (City of Industry, California). The detector 62 may be an ultra thin-film metal-semiconductor-metal (MSM) photodetector. In embodiments, the emitter 60 and the detector 62 may protrude less than about Imm, or less than about 0.5mm from the interior surface 64 of the hat band 26. In certain embodiments, the emitter 60 and the detector may protrude about 0.25mm to about Imm from the interior surface 64 of the hat band 26.

A sensor assembly may also include structures, such as a pocket in the fabric, to allow the sensing components to lie flush or substantially flush against the interior surface of the hat band, which may facilitate a conforming fit against the tissue. In turn, this conforming fit may improve measurement accuracy, for example by reducing light being shunted from an emitter 60 to a detector 62.
As shown in FIG. 4, a hat assembly 70 may include a buttonhole or other pocket 76 formed on the interior surface 64 of the hat band 26 that may be sized and shaped to accommodate the emitter 60 and the detector 62. In such embodiments, the emitter 60 and the detector 62 may be disposed on a thin and flexible backing, such as a fabric or paper backing 78 that is sized and shaped to fit into pocket 76 and may provide shielding to the emitter 60 and the detector 62. It should be understood that the pocket 76 may be sufficiently deep so that the emitter 60 and the detector 62 may not substantially protrude from the interior surface 64 of the hat band 26. In embodiments, the backing 78 may assist in positioning the emitter 60 and the detector 62 to lie flush with the interior surface 64 of the hat band 26.

The sensor assemblies as provided may include addition features to facilitate a secure and comfortable fit while also maintaining relatively flexible arrangements of optical sensing components. A sensor assembly 72 may include a gripping portion 74,which may be a layer applied to the interior of the hat band 26, as shown in cross-section in FIG. 5. The emitter 60 and the detector 62 may be adhered or otherwise secured to the gripping portion 74. The gripping portion may be applied to the interior of a hat band 26 such that the tissue-contacting surface 76 of the gripping portion 74 may facilitate holding the sensor assembly 72 on the tissue. For example, a suitable gripping portion 74 may be made of plastic, rubber, silicone, vinyl, or woven material. In an embodiment, the gripping portion may be a relatively thin, flexible material such as Super Grip@ Easy Liner (Henkel) that is disposed on the interior of the hat 12, such as on the hat band 26.
The gripping portion 74 may be thin and highly flexible, while also having properties such as a high coefficient of friction that may help hold the emitter 60 and the detector 62 in place. In certain embodiments, the gripping portion 74 is formed from a material that has a relatively large static coefficient of friction. A
material with a large static coefficient of friction helps to keep sensor stable relative to the skin as a patient moves. The static coefficient of friction of a material may be tested using the following procedure: (1) Attach a protractor to a vertical wall with the center in line with the edge of a table. (2) Set up a stop block at the edge of the table to act as a pivot point for a glass plate. (3) Place the glass plate flat on the table with one edge along the edge of the table, up against the stop block. (4) Place a test sample of the material on the glass plate. (5) Lift the free edge of the glass plate until the test sample just starts to slip. (6) Record angle at which slippage first occurred. This angle is the angle of repose. Then calculate the coefficient of friction, which is the tangent of the angle of repose. The static coefficient of friction for gripping portion 74 may greater than 10. In certain embodiments, the static coefficient of friction for gripping portion 74 may be greater than 100. The gripping portion 74 may be a material that has a high static coefficient of friction relative to glass, such as polyvinyl chloride (PVC) foam. In embodiments, it may be desirable to calculate a static coefficient of friction of a material relative to a patient's skin. In certain embodiment, the gripping portion 74 has a static coefficient of friction greater than 5 with respect to a patient's skin The foregoing sensors and sensor assemblies provided herein may be used in conjunction with any suitable medical device. A sensor or sensor assembly, illustrated generically as a sensor assembly 10, may be used in conjunction with a pulse oximetry monitor 90, as illustrated in FIG. 6. It should be appreciated that the cable 20 of the sensor assembly 10 may be coupled to the monitor 90 or it may be coupled to a transmission device to facilitate wireless transmission between the sensor assembly 10 and the monitor 90. The monitor 90 may be any suitable pulse oximeter, such as those available from NeIleor Puritan Bennett LLC.
Furthermore, to upgrade conventional pulse oximetty provided by the monitor 90 to provide additional functions, the monitor 90 may be coupled to a multi-parameter patient monitor 92 via a cable 94 connected to a sensor input port or via a cable 96 connected to a digital communication port.
FIG. 7 is a block diagram of an embodiment of a monitor 90 that may be configured to implement the embodiments of the present disclosure, Light from optical fiber 16 (or, in embodiments in which optical fibers 16 are not used, light directly from emitter 60) may pass into a blood perfused tissue, and may be scattered, and then detected by detector 62, which may be coupled to one or more optical fibers 16. A sensor assembly 10 including optical fibers 16 (or, in embodiments, an emitter 60 and a detector 62) may also contain an encoder 100 which may be capable of providing signals indicative of the wavelength(s) of light source 60 to allow the oximeter to select appropriate calibration coefficients for calculating oxygen saturation. The encoder 100 may, in an embodiment, be a resistor or may be a storage device, such as a memory.

In an embodiment, the sensor assembly 10 may be connected to a pulse oximetry monitor 90. The monitor 90 may include a microprocessor 102 coupled to an internal bus 104. Also connected to the bus may be a RAM memory 106 and a display 108. A time processing unit (TPU) 110 may provide timing control signals to light drive circuitry 112, which controls when the emitter 60 is activated, and if multiple light sources are used, the multiplexed timing for the different light sources. TPU 110 may also control the gating-in of signals from detector 62 through an amplifier 113 and a switching circuit 114. These signals are sampled at the proper time, depending at least in part upon which of multiple light sources is activated, if multiple light sources are used. The received signal from the detector 62 may be passed through an amplifier 116, a low pass filter 118, and an analog-to-digital converter 120. The digital data may then be stored in a queued serial module (QSM) 122, for later downloading to RAM 106 or ROM 126 as QSM 122 fills up.

In an embodiment, based at least in part upon the received signals corresponding to the light received by detector 62, microprocessor 122 may calculate the oxygen saturation using any suitable algorithm. Such algorithms may use coefficients, which may be empirically determined, and may correspond to the wavelengths of light used. The algorithms may be stored in a ROM 126 and accessed and operated according to microprocessor 122 instructions. For example, the encoder 100 may communicate with decoder 128 to allow the microprocessor 122 to determine the appropriate coefficients.

In an embodiment of a two-wavelength system, the particular set of coefficients chosen for any pair of wavelength spectra may be determined by a value indicated by the encoder 100 corresponding to a particular light source in a particular sensor assembly 10. In one embodiment, multiple resistor values may be assigned to select different sets of coefficients. In another embodiment, the same resistors are used to select from among the coefficients appropriate for an infrared source paired with either a near red source or far red source. The selection between whether the near red or far red set will be chosen can be selected with a control input from control inputs 134. Control inputs 134 may be, for instance, a switch on the pulse oximeter, a keyboard, or a port providing instructions from a remote host computer. Furthermore, any number of methods or algorithms may be used to determine a patient's pulse rate, oxygen saturation or any other desired physiological parameter.

The sensor assembly 10 may be connected to or include an emitter 60 and a detector 62 that may be of any suitable type. For example, the emitter 60 may be one or more light emitting diodes adapted to transmit one or more wavelengths of light in the red to infrared range, and the detector 62 may one or more photodetectors selected to receive light in the range or ranges emitted from the emitter 60. Alternatively, an emitter 60 may also be a laser diode or a vertical cavity surface emitting laser (VCSEL). Alternatively, a sensor assembly 10 may sense light detected from the tissue is at a different wavelength from the light emitted into the tissue. Such sensors may be adapted to sense fluorescence, phosphorescence, Raman scattering, Rayleigh scattering and multi-photon events or photoacoustic effects.

For pulse oximetry applications using either transmission or reflectance type sensors the oxygen saturation of the patient's arterial blood may be determined using two or more wavelengths of light, most commonly red and near infrared wavelengths. Similarly, in other applications, a tissue water fraction (or other body fluid related metric) or a concentration of one or more biochemical components in an aqueous environment may be measured using two or more wavelengths of light, most commonly near infrared wavelengths between about 1,000 rim to about 2,500 nm. It should be understood that, as used herein, the term "light" may refer to one or more of ultrasound, radio, microwave, millimeter wave, infrared, visible, ultraviolet, gamma ray or X-ray electromagnetic radiation, and may also include any wavelength within the radio, microwave, infrared, visible, ultraviolet, or X-ray spectra.

Reflectance type sensors also operate by emitting light into the tissue and detecting the light that is transmitted and scattered by the tissue. However, reflectance type sensors include an emitter 60 and detector 62 that are typically placed on the same side of the sensor site. Alternatively, side-by-side optical fibers 16 or a single multi-mode optical fiber 16 may be used for reflectance measurements. For example, a reflectance type sensor may be placed on a patient's fingertip or forehead such that the emitter 60 and detector 62 lie side-by-side.

Reflectance type sensors detect light photons that are scattered back to the detector 62. A sensor assembly 10 may also be a "transfiectance" sensor, such as a sensor that may subtend a portion of a baby's heel. In embodiments, contemplated sensor assemblies may be sock-type or glove-type assemblies.

While the disclosure may be susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and have been described in detail herein. However, it should be understood that the embodiments provided herein are not intended to be limited to the particular forms disclosed. Indeed, the disclosed embodiments may not only be applied to measurements of blood oxygen saturation, but these techniques may also be utilized for the measurement and/or analysis of other blood constituents.
