Abstract

A blood analyzer device has a housing with a top section coupled to a bottom section, a driver and a plurality of penetrating members housed in a disposable positionable in the housing. A gripper engages each penetrating member. A manually actuated button advances the disposable to move penetrating members into launch positions. A power is source coupled to the driver. A display is at the housing.

Claims

1. A blood analyzer device, comprising:

a housing;

a penetrating member driver positioned in the housing;

a plurality of penetrating members housed in a disposable positionable in the housing;

a gripper assembly that includes a gripper that engages a penetrating member of the plurality of penetrating members with the driver prior to launch of a penetrating member during a lancing event, an open channel that is positioned over the gripper in the gripper assembly, a gripper shaft assembly including a flag, a non-polymeric rod, a polymeric gripper shaft, a magnet and a stepped gripper portion that captures and retains a penetrating member;

an actuator assembly that includes a gripper track coupled to the gripper assembly, a sensor, and a gripper insertion arm;

a sweeper arm coupled to the gripper assembly, the sweeper arm configured to physically retain the gripper assembly and prevent it from accidentally exiting the housing; and

a power source coupled to a drive assembly and the penetrating member.

2. The device of claim 1, further comprising:

a sterility barrier that maintains the plurality of penetrating members in a sterile environment.

3. The device of claim 1, further comprising:

a mechanical assembly that includes a cam.

4. The device of claim 1, further comprising:

a sterility barrier opener that moves a sterility barrier out of the way of a launched penetrating member.

5. The device of claim 4, wherein a sterility barrier opener is a punch that moves at least a portion of the sterility barrier out of a way of a launched penetrating member.

6. The device of claim 5, wherein the punch lifts up at least a portion of the sterility barrier.

7. The device of claim 1, wherein the power source is a battery.

8. The device of claim 5, further comprising:

battery contacts.

9. The device of claim 1, further comprising:

a door assembly.

10. The device of claim 9, further comprising:

a door latch.

11. The device of claim 10, further comprising:

a door latch retainer.

12. The device of claim 1, wherein the top section of the housing includes a window.

13. The device of claim 12, further comprising:

a removable window protection film.

14. The device of claim 13, further comprising:

a display.

15. The device of claim 14, wherein the display is a liquid crystal display.

16. The device of claim 15, further comprising:

a liquid crystal display gasket positioned between the housing and the liquid crystal display.

17. The device of claim 1, wherein the housing includes a finger interface section.

18. The device of claim 17, wherein the finger interface section is indented.

19. The device of claim 18, wherein the finger interface section is conformable to an anatomy of a fingertip.

20. The device of claim 1, further comprising:

a fire button that launches penetrating members.

21. The device of claim 1, further comprising:

a slider handle.

22. The device of claim 1, further comprising:

a sterility barrier detect spring.

23. The device of claim 1, further comprising:

a sweeper arm motor assembly.

24. The device of claim 1, further comprising:

a ratchet tension spring.

25. The device of claim 1, further comprising:

an indexer.

26. The device of claim 1, further comprising:

a drive gear.

27. The device of claim 1, further comprising:

a bobbin.

28. The device of claim 1, further comprising:

a bobbin retainer.
