Abstract

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.

Claims

1. A lancing system, comprising:

a disposable having a plurality of cavities; and

a plurality of penetrating members at least partially contained in said cavities of the single disposable wherein the penetrating members are slidably movable to extend outward from lateral openings on said disposable to penetrate tissue; and

a penetrating member gripper that couples a penetrating member driver to each of a penetrating member during a launch of a penetrating member,

2. The system of claim 1, wherein the penetrating member gripper is not positively coupled to the disposable.

3. The system of claim 1, wherein the gripper has leg portions defining said slot, said legs movable elastically to receive the bare lancet.

4. The system of claim 1, wherein the gripper has a tuning fork shaped configuration.

5. The system of claim 1, wherein the gripper moves vertically relative to the lancet to engage an elongate portion of the lancet.

6. The system of claim 1, further comprising:

a gripper block for coupling the gripper to a driver.

7. A method comprising:

loading a disposable having a plurality of penetrating members into a housing of a lancing apparatus;

releasing said penetrating member from the disposable;

transporting said penetrating member within the housing towards a launch position;

loading said lancet to be operatively coupled to a penetrating member driver in the apparatus.

8. The method of claim 7, wherein said releasing of said penetrating member comprises using a punch to penetrate a sterility barrier of a cavity adjacent a cavity in the launch position.

9. The method of claim 7, wherein said transporting comprises rotating said disposable to move said cavity with the released penetrating member into the launch position.

10. The method of claim 7, wherein loading comprises creating a frictional coupling between the penetrating member and the driver.

11. The method of claim 7, wherein loading comprises moving the disposable relative to the driver to bring the driver into contact with the released penetrating member.

12. A method comprising:

providing a disposable having a plurality of individual cavities each containing a penetrating member;

rotating the disposable to align the unused penetrating member with a gripper;

creating a frictional engagement with the penetrating member by inserting the penetrating member into a receiving slot on the gripper.

13. A lancing system, comprising:

a plurality of penetrating members at least partially contained in said cavities of the single disposable wherein the penetrating members are slidably movable to extend outward from lateral openings on said disposable to penetrate tissue; and

a penetrating member gripper that couples a penetrating member driver to each of a penetrating member during a launch of a penetrating member,

14. The system of claim 13, wherein the penetrating member gripper is not positively coupled to the disposable.

15. The system of claim 13, wherein the gripper has leg portions defining said slot, said legs movable elastically to receive the bare lancet.

16. The system of claim 13, wherein the gripper has a tuning fork shaped configuration.

17. The system of claim 13, wherein the gripper moves vertically relative to the lancet to engage an elongate portion of the lancet.

18. The system of claim 13, further comprising:

a gripper block for coupling the gripper to a driver.

19. A method comprising:

loading a disposable having a plurality of penetrating members into a housing of a lancing apparatus;

releasing said penetrating member from the disposable;

transporting said penetrating member within the housing towards a launch position;

loading said lancet to be operatively coupled to a penetrating member driver in the apparatus; and

using a penetrating member gripper to couple a penetrating member driver to each of a penetrating member during a launch of a penetrating member.

20. The method of claim 19, further comprising:

using a punch to penetrate a sterility barrier of a cavity adjacent a cavity in the launch position.

21. The method of claim 19, wherein said transporting comprises rotating said disposable to move said cavity with the released penetrating member into the launch position.

22. The method of claim 19, wherein loading comprises creating a frictional coupling between the penetrating member and the driver.

23. The method of claim 19, wherein loading comprises moving the disposable relative to the driver to bring the driver into contact with the released penetrating member.

24. A method comprising:

providing a disposable having a plurality of individually sealed cavities each containing a penetrating member;

rotating the disposable to align the unused penetrating member with a gripper;

creating a frictional engagement with the penetrating member by inserting the penetrating member into a receiving slot on the gripper.
