Abstract

Analyte meter protectors, meters that include the same, and methods.

Claims

1. An in vivo glucose monitoring system that comprises an integrated in vitro monitoring system, the system comprising:

an in vitro glucose test strip;

an in vivo glucose module comprising an integrated in vitro glucose test strip port to contact the in vitro glucose test strip; and

a port protector mateable about the test strip port of the module to provide a substantially fluid tight seal about the test strip port, wherein the port protector includes an engagement feature that serves to align and attach the port protector to the test strip port, wherein the port protector comprises a slot to permit passage of an in vitro ketone test strip through the slot and into the port, and wherein the protector slot provides contact across both top and bottom surfaces of the in vitro glucose test strip when the test strip is passed therethrough.

2. The continuous glucose monitoring system of claim 1, wherein the port protector slot is dimensioned so that it does not apply pressure to an in vitro glucose test strip when the test strip is passed therethrough.

3. The continuous glucose monitoring system of claim 1, wherein the area of the port protector slot is less than the area of the port.

4. The continuous glucose monitoring system of claim 1, wherein the in vitro glucose test strip port is configured to provide a clearance between a surface of the protector slot and a surface of an in vitro glucose test strip when the test strip is passed therethrough.

5. The continuous glucose monitoring system of claim 1, wherein the port protector is removably attachable to the module.

6. The continuous glucose monitoring system of claim 1, wherein the protector is fixedly attachable to the module.

7. The continuous glucose monitoring system of claim 1, wherein the engagement feature comprises adhesive.

8. The continuous glucose monitoring system of claim 1, wherein the glucose test strip is configured to test for glucose in a sample of no more than about 1 microliter.

9. The continuous glucose monitoring system of claim 8, wherein the glucose test strip is configured to test for glucose in a sample of no more than about 0.5 microliter.

10. The continuous glucose monitoring system of claim 9, wherein the glucose test strip is configured to test for glucose in a sample of no more than about 0.2 microliter.

11. An in vivo glucose monitoring system, comprising:

an in vivo glucose sensor at least partially implanted within a patient;

an in vivo glucose module electrically coupled to the sensor, wherein the module includes an integrated electrochemical analyte meter having a port that provides an opening to an interior portion of the module; and

a port protector attachable to the module about the port, wherein the port protector includes,

an interface surface forming a fluid tight seal between the module and the port protector,

a slot configured to receive an analyte test strip and provide a substantially fluid tight seal to the interior portion of the module, wherein the slot provides contact across both top and bottom surfaces of the analyte test strip when the test strip is passed therethrough

a ledge extending from the slot to guide the analyte test strip into the slot, and

engagement features that serve to attach the port protector to the module.

12. The system of claim 11, further comprising:

a flexible valve disposed at least partially across the slot, wherein the flexible valve includes a self-sealing slit.

13. The system of claim 11, wherein the interface surface of the port protector corresponds to a surface of the module about the port so as to form a negative of the surface of the module.

14. The system of claim 11, wherein the port protector is formed of an elastomeric material.

15. The system of claim 11, wherein the port protector includes a hard plastic frame with a compliant area around the slot.

16. An in vivo glucose monitoring system, comprising:

an in vivo glucose sensor at least partially implanted within a patient;

an in vivo glucose module electrically coupled to the sensor, wherein the module includes an integrated analyte meter having a port that provides an opening to an interior portion of the module; and

a port protector attachable to an exterior surface of the module about the port, wherein the port protector includes,

an interface surface forming a fluid tight seal between the exterior surface of the module and the port protector, wherein the interface surface is a negative of the exterior surface of the module about the port,

a slot configured to receive an analyte test strip and provide a substantially fluid tight seal to the interior portion of the module,

a ledge extending from the slot to guide the analyte test strip into the slot,

two guide grooves positioned on opposing sides of the port protector,

a flexible valve disposed at least partially across the slot,

molded features that align the port protector with the port, and

engagement ribs to attach the port protector to the module.

17. The system of claim 16, further comprising an adhesive applied to the interface surface of the port protector.

18. The system of claim 16, wherein the port protector is formed of an elastomeric material.

19. The system of claim 16, wherein the port protector includes a hard plastic frame with a compliant area around the slot.

20. A glucose monitoring system, comprising:

an in vivo glucose sensor;

an in vivo glucose module in electrical communication with the glucose sensor;

an in vitro analyte meter integrated with the in vivo glucose module, wherein the in vitro analyte meter includes a test strip port that defines an opening to an interior portion of the meter and is configured to receive an in vitro test strip; and

a port protector coupled to the test strip port, wherein port protector is configured to provide a substantially fluid tight seal to the interior portion of the module, and wherein the port protector includes an engagement feature that serves to align and attach the port protector to the test strip port, wherein the port protector comprises a slot to permit passage of the in vitro test strip through the slot and into the port, and wherein the protector slot provides contact across both top and bottom surfaces of the in vitro glucose test strip when the test strip is passed therethrough.

21. The system of claim 20, wherein an interface surface on the port protector corresponds to a surface of the module so as to form a negative of the surface of the module.

22. The system of claim 20, wherein the port protector is formed of an elastomeric material.

23. The system of claim 20, wherein the port protector includes a hard plastic frame with a compliant area for introduction of the in vitro test strip.
