Abstract

An integrated medical testing device includes a testing meter and lancing device, the meter having a housing, a display, a test element opening, a firing mechanism and a navigation mechanism integrated with a lancing device. The lancing device is at least partially located in the housing and includes a tip having an opening through which a lancet extends upon firing. Various mechanisms can be used to extend the tip from the housing and to prime and fire the lancing device. The lancing device can accommodate a single lancet or a cartridge having multiple lancets. If a cartridge is used, various mechanisms can be utilized to position an unused lancet for firing after a test has been conducted. The relative locations of the lancing device and test element opening are such that the integrated meter and lancing device can be used with a test element inserted in the test element opening. The integrated meter and lancing device can include status indicators that reflect the state of the lancing device.

Claims

1. A medical testing device, including:

a blood testing meter having a housing;

a lancing device including a lancet and a tip movable from a first position located at least partially within the housing to a second position located at least partially outside the housing; and

means for priming the lancing device for movement of the lancet from the first position to the second position.

2. The medical testing device according to claim 1, wherein the means for priming includes a tip on the lancing device movable from a first position to a second position.

3. The medical testing device according to claim 1, wherein the means for priming includes an opening in the housing for receiving a test element and wherein inserting a test element into the opening primes the lancet.

4. The medical testing device according to claim 1, wherein the means for priming includes a cover movable from a first position on the housing to a second position on the housing.

5. The medical testing device according to claim 1, wherein the means for priming includes a lever movable from a first position to a second position.

6. The medical testing device according to claim 1, further including an indicator for indicating whether the lancet is in the primed or unprimed state.

7. The medical testing device according to claim 6, further including a display and wherein the indicator appears on the display.

8. The medical testing device according to claim 1, wherein the means for priming includes a display movable from a first position located at least partially within the housing to a second position located at least partially outside the housing.

9. The medical testing device according to claim 1, further including a display and wherein the means for priming includes a cover movable from a first position over the display to a second position exposing the display.

10. The medical testing device according to claim 1, wherein the means for priming includes a display movable from a first position facing the housing to a second position.

11. The medical testing device according to claim 1, wherein the means for priming includes a button located on the housing.

12. The medical testing device according to claim 11, wherein depressing the button moves it from a storage position to a use position.

13. The medical testing device according to claim 12, wherein depressing the button a second time primes the lancet.

14. The medical testing device according to claim 13, wherein depressing the button a third time fires the lancet.

15. The medical testing device according to claim 1, further including a cartridge containing at least two lancets located at least partially within the housing and an opening in the housing through which the lancet extends when it is in the second position.

16. The medical testing device according to claim 15, wherein the cartridge is configured to move after a lancet is fired to align an unused lancet with the opening.

17. The medical testing device according to claim 15, further including an indicator displaying the number of unused lancets in the cartridge.

18. The medical testing device according to claim 15, further including an indicator displaying the number of used lancets in the cartridge.

19. The medical testing device according to claim 15, further including an actuator for moving the cartridge.
