Abstract

The present disclosure provides a contamination resistant sensor port which includes one or more sealing members positioned so as to limit and/or prevent internal contamination of the sensor port with fluids and/or particles present in the environment outside the sensor port.

Claims

1. A sensor port, the sensor port comprising:

a housing, the housing comprising a body and a protruding member, the protruding member defining an entry slot configured to receive an analyte sensor; and

a first sealing member positioned on the protruding member and circumscribing the protruding member, wherein the first sealing member is configured to form a seal between the sensor port and an electrical device.

2. The sensor port of claim 1, wherein the body defines a first opening and a second opening, and the sensor port further comprises:

a second sealing member positioned on the body of the housing such that a seal is formed over the first opening; and

a third sealing member positioned on the body of the housing such that a seal is formed over the second opening.

3. The sensor port of claim 2, wherein the second and third sealing members each comprise an adhesive backing which provides for attachment to the body of the housing.

4. The sensor port of claim 3, wherein the second and third sealing members each comprise polyimide film tape.

5. The sensor port of claim 1, wherein the protruding member comprises a channel which circumscribes the protruding member, and wherein the first sealing member is positioned in the channel

6. The sensor port of claim 5, wherein the channel defines an oval.

7. The sensor port of claim 1, wherein the electrical device is an analyte meter.

8. The sensor port of claim 7, wherein the analyte meter is a glucose meter.

9. The sensor port of claim 8, wherein the analyte sensor is a glucose test strip.

10. The sensor port of claim 1, wherein the first sealing member is a compliant gasket material.

11. The sensor port of claim 10, wherein the compliant gasket material comprises an elastomeric material.

12. The sensor port of claim 10, wherein the compliant gasket material is an o-ring.

13. The sensor port of claim 1, wherein the entry slot comprises an internal beveled face.

14. The sensor port of claim 1, wherein the housing comprises an injection molded plastic.

15. The sensor port of claim 1, wherein the housing comprises a top portion and a bottom portion which are joined to form the sensor port.

16. The sensor port of claim 1, wherein the sensor port is integrated in and operably connected to an electrical device.

17. The sensor port of claim 16, wherein the electrical device is an analyte meter.

18. The sensor port of claim 17, wherein the analyte meter is a glucose meter.

19. The sensor port of claim 16, wherein electrical device is an integrated continuous glucose monitor receiver.

20. The sensor port of claim 16, wherein the electrical device is a medication delivery device.

21. The sensor port of claim 20, wherein the medication delivery device is a pump.

22. The sensor port of claim 20, wherein the medication is insulin.

23. The sensor port of claim 1, wherein the first sealing member provides a substantially fluid-tight seal between the sensor port and the electrical device.

24. A medication delivery device comprising:

a sensor port, wherein the sensor port comprises;

a housing, the housing comprising a body and a protruding member, the protruding member defining an entry slot configured to receive an analyte sensor; and

a first sealing member positioned on the protruding member and circumscribing the protruding member, wherein the first sealing member forms a seal between the sensor port and the medication delivery device.

25. The medication delivery device of claim 24, wherein the body defines a first opening and a second opening;

and the sensor port further comprises;

a second sealing member positioned on the body of the housing such that a seal is formed over the first opening; and

a third sealing member positioned on the body of the housing such that a seal is formed over the second opening.

26. The medication delivery device of claim 25, wherein the second and third sealing members each comprise an adhesive backing which provides for attachment to the body of the housing.

27. The medication delivery device of claim 26, wherein the second and third sealing members each comprise polyimide film tape.

28. The medication delivery device of claim 24, wherein the protruding member comprises a channel which circumscribes the protruding member, and wherein the first sealing member is positioned in the channel

29. The medication delivery device of claim 28, wherein the channel defines an oval.

30. The medication delivery device of claim 24, wherein the analyte sensor is a glucose test strip.

31. The medication delivery device of claim 24, wherein the first sealing member is a compliant gasket material.
