Abstract

An analyte and detecting apparatus includes a housing, an access door and a front end aperture. A module is positionable in the housing. A penetrating member is positioned in the module and upon launch passes through the front end aperture. An analyte sensor is positioned in the module. A penetrating member driver is configured to be coupled to the penetrating member. A mechanism is included that moves an arm coupled to the penetrating member driver into a launch position and allows motion of the penetrating member driver.

Claims

1. An analyte detecting apparatus, comprising:

a housing and an access door and a front end aperture;

a module positionable in the housing;

a penetrating member positioned in the module and upon launch passes through the front end aperture;

an analyte sensor positioned in the module;

a penetrating member driver configured to be coupled to the penetrating member; and

a mechanism that moves an arm coupled to the penetrating member driver into a launch position and allows motion of the penetrating member driver.

2. The apparatus of claim 1, wherein application of pressure from a finger on the front end aperture begins a first sequence of the penetrating member.

3. The apparatus of claim 1, further comprising:

a display positioned at an exterior of the housing that displays a reading associated with analyte measurement.

4. The apparatus of claim 1, wherein the module is an injection molded plastic body that cradles the penetrating member and holds the analyte sensor.

5. The apparatus of claim 1, further comprising:

at least one seal that protects for at least one of sterility and humidity.

6. The apparatus of claim 1, further comprising:

a first seal at a top of the module and a second seal at a bottom of the module.

7. The apparatus of claim 1, further comprising:

a sweeper arm; and

a lever coupled to the sweeper arm to move the sweeper arm in a launch position.

8. The apparatus of claim 7, wherein in the launch position the sweeper arm allows free motion of the penetrating member driver.

9. The apparatus of claim 1, further comprising:

a first seal breach device, wherein in response to movement of the module relative to the first seal breach device, a seal associated with the analyte sensor is opened.

10. The apparatus of claim 9, further comprising:

a second seal breach device, wherein in response to movement of the module, in response to a closure of the access door the second seal breach device opens a seal associated with the penetrating member.

11. The apparatus of claim 1, further comprising:

a penetrating member engagement member that engages the penetrating member to the penetrating member driver, in response to a closure of the access door, the penetrating member becomes engaged with the penetrating member engagement member.

12. The apparatus of claim 1, further comprising:

a spring that is compressed as the access door closes.

13. The apparatus of claim 12, further comprising:

a switch that indicates when the module is fully seated and the penetrating member is gripped and ready to launch.

14. The apparatus of claim 13, wherein when the access door is released, the spring lifts the module and allows free motion of the penetrating member engagement member during a penetrating member actuation sequence.

15. The apparatus of claim In FIG. 7, further comprising:

an activation element positioned at an exterior of the housing that engages with the sweeper arm.
