Description

A KEYING MECHANISM FOR A FINGER-TYPE PERISTALTIC INFUSION PUMP WHICH IS INTERCONNECTED WITH ONE OF A PLURALITY OF PASSIVE MECHANICAL INTERFACES
FIELD OF THE INVENTION
The present invention pertains to a keying mechanism for a finger-type peristaltic infusion pump which is interconnected with one of a plurality of passive mechanical interfaces.
BACKGROUND OF THE INVENTION
Today, when a hospital or any other entity/institution/body supplying medical services is required to acquire medical pumps, it must usually purchase a number of different types of pumps from the same manufacturer or different manufacturers, such that each pump can perform one kind of treatment, or a limited number of treatment types/protocols/schedules.
The commercially available Q-Core pump is a commercially available peristaltic pump which embodies a flexible technological platform which allows a large range of treatment types/schedules/protocols to be given. In fact, suffice it to say, that on the basis of the Q-Core pump technological platform, all treatments/protocols/schedules existing today can be administered.
Procurement and stocking of Q-Core pumps of this type by hospitals and medical institutions confers many advantages, including common and uniform spare part stocks, ease of training maintenance staff, uniform calibration protocols, ease of training medical staff (common human / treatment interface etc.).
In fact, the sole difference to the user of each treatment is in the operating protocol for each treatment (based always on the same GUI and MMI) and the use of different sets (tube system, medicinal fluid container and connectors to the patient)
The peristaltic pump, e.g., such commercially available epidural pumps, is a pump which utilizes yellow leaved tubes, the required pressure gradient supplied by the pump and the set is usually different from the more commonly required pressures required for other procedures, the pulses are lower than those required for infusion protocols and the dosage accuracy required from the pump and the set is greater. Matching the appropriate set required for a specific treatment can be determined by distinguishing markings on the set and the specific working protocols. It is no longer necessary to provide an engineering solution such as a "one-way-key system" to allow fitting between different sets and different pumps, according to the treatments described for them.
Literature survey have reveled that there are no commercially available pumps whose mechanical or electronic key allows, by means of the pump setup, unique key code changes for specific use of different sets with the same pump. It is therefore the purpose of the invention described here to provide an alterable mechanical key code interface, which will enable different sets to be uniquely matched to the same pump.

It is according to another embodiment of the present invention wherein the system as defined in any of the above comprises of a master keying mechanism, wherein at least one MS is adapted to be utilized in a plurality of all DDS' pumping mechanisms.
It is according to another embodiment of the present invention the master keying mechanism is adapted to match at least one MS of a given characterization with a plurality of N predetermined DDS' pumping mechanisms; N is any integer number, selected from either defined or not defined number of MS-DDS possible combinations.
It is according to another embodiment of the present invention wherein the keying mechanism is provided by a means of an MS that is characterized by upstream and downstream opposite ends, said MS comprises a saddle-like catch (saddle), located e.g., at the downstream end of the MS; said DDS comprises a barrel-like axle (barrel) of the DDS, located e.g., at the downstream portion of said DDS; wherein said barrel is adapted to fit the saddle by means of shape and size such that (a) a two-parts hinge is provided at time said saddle and barrel are integrated and (b) complete matching between said DDS' pumping protocol and said specified MS is ensured.
It is according to another embodiment of the present invention wherein the keying mechanism comprises a single integral geometric mechanical interface that ensures complete matching between said DDS' pumping protocol and said specified MS; said mechanical interface is characterized by at least two dimensions of said female subunits or male subunits, especially in (a) a mechanism wherein one dimension increases, the second respectively decreases; (b) a mechanism wherein one dimension increases, the second respectively increases; and especially wherein said dimensions are selected from size, diameter or a combination thereof.
It is according to another embodiment of the present invention wherein the user being either the patient or preferably the hospital personnel defines one or more specific infusion protocol or protocols in the DDS. For that infusion protocol, a specific MS is utilized. This specific MS controls inter alia tube characteristics. More specifically, a master MS device can be used, wherein a keying mechanism is to be replaced so it is correlated with the aforesaid pumping protocol. According to one embodiment of the present invention, provided hereinafter as a best mode, the keying mechanism is the barrel-axle of the MS-DDS interface, especially on the DDS in a location facing the saddle of the MS.

Table 1 Series of five different combinations between saddle & barrel (width and diameter)
Combination Saddle Saddle Barrel Barrel width diameter width diameter b d B D
1 5.8 2 5.8 2
2 5.6 2.2 5.6 2.2
3 5.4 2.4 5.4 2.4
4 5.2 2.6 5.2 2.6
5 5 2.8 5 2.8
Table 1 shows that a saddle characterized by d=2.4 and b=5.4 fits only with a barrel characterized by D=2.4 and B=5.4 (See Combination No. 3). It is acknowledged in this respect that Saddles with dimensions of 2.8, 2.6 can be forced to fit barrels of 2.4 diameter, yet their width is too narrow (less than 5.4) so as such a false matching can not be achieved. Similarly, saddles characterized by b>5.4, such as 5.6 and 5.8, can be force to fit a barrel of B=5.4, yet due to narrow diameter, such a false matching can not be achieved. Master keying is provided useful wherein one saddle can fit to three barrels in the manner that saddle sizes are d=2.8, b=5.4 and combinations 3-5 are achievable.
It is also in the scope of the present invention to disclose a method of keying a finger-type peristaltic infusion pump (DDS) operated by a specified pumping protocol, the DDS is interconnected with one of a plurality of passive mechanical interface (MS) that accommodates a portion of a flexible infusion-tube, preferably wherein a specified MS is adapted form a specific infusion protocol that correlates with said pumping protocol; comprising applying an integral geometric mechanical interface that ensures complete matching between said DDS1 pumping protocol and said specified MS.
It is further in the scope of the present invention wherein the keying of DDS with MS is provided by a 3D key-and-lock mechanism of a set barrel and the saddle, and wherein this set is adapted to fit a given DDS protocol, namely, to specifically match (i) a specific DDS (e.g., a specific infusion pump provided for certain use); (U) a specific MS, such as a patient- targeted MS, a user-targeted MS, a treatment-targeted MS, a medicament-targeted MS etc; or any combination of the two.
It is still in the scope of the present invention wherein the integral geometric interface comprises two or more replaceable mechanical subunits and/or two or more unrelated physical dimensions, such that by replacing one or more subunits alters, a specific DDS' pumping protocol and correlated MS is selected. Its is acknowledged in this respect that the lock-and-key mechanism of the barrel and saddle provides the designer to correlate between the specific set of DDS and MS: for example, by using a first keying facilities (e.g., male lock) characterized by a certain 2D or 3D keying value (e.g., width and diameter), any second keying facility having bigger 2D or 3D keying values will be able to connect said first keying facility. Yet, as disclosed and defined in the present invention, by utilizing a first keying facilities (here both male and female lock) characterized by a certain 2D or 3D keying value (e.g., width and diameter), any second keying facility with corresponding male and female 2D or 3D keying values, only said second keying facility can by affixed with said first keying facility.
