Method and apparatus for a multi-use body fluid sampling device with sterility barrier release
View Patent ↗A device for use with a gripper is provided. A cartridge is provided that defines a plurality of cavities. A plurality of penetrating members are at least partially contained in the cavities of the cartridge. The penetrating members are slidably movable to extend outward from the cartridge to penetrate tissue. Each cavity has a longitudinal opening that provides access to an elongate portion of the penetrating member. A sterility barrier is coupled to the cartridge. The sterility barrier covers a plurality of the longitudinal openings. The sterility barrier is configured to be moved so that the elongate portion is accessed by the gripper without touching the barrier.
1. A device for use with a gripper, the device comprising:
a housing;
a disposable configured to be positioned in the housing
a plurality of sample chambers positioned in the disposable, each of a sample chamber including an analyte detecting member;
a fracturable seal coupled to the disposable, the fracturable seal covering a plurality of openings, each of an opening being associated with the sample chamber;
a punch positioned and movable to penetrate the fracturable seal covering the plurality of opening associated with the sample chambers;
a light source and a detector disposed in the housing, the light source configured to illuminate an area of one of the openings and the detector configured to detect light reflected from the area illuminated.
2. The device of claim 1 , wherein the fracturable seal covering the openings is configured to be punched downward.
3. The device of claim 1 wherein the fracturable seal covering the openings at least partially breaks.
4. The device of claim 1 wherein the fracturable seal is made of a material containing one of the following: aluminum, polymer, and paper.
5. The device of claim 1 wherein the fracturable seal is made of a laminate made from one of the following: aluminum, polymer, and paper.
6. The device of claim 1 wherein said disposable includes a plurality of indentations for assisting in disposable indexing.
7. The device of claim 1 wherein said disposable includes a plurality of indentations substantially adjacent an inner radial surface of the disposable for assisting in disposable indexing.
8. The device of claim 1 wherein said plurality of sample chambers are substantially in a common plane.
