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 extending from the body and having a distal end, wherein the distal end comprises an entry slot to receive an analyte sensor; and

a first sealing member circumscribing the protruding member and positioned wholly between the entry slot and the body of the housing, wherein the first sealing member is configured to form a seal between the sensor port and an electrical device into which the sensor port is integrated.

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 between the entry slot and the body of the housing, 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 6, wherein the flush surface at the distal end defines an oval.

8. The sensor port of claim 7, wherein the oval defined by the channel aligns in a distal direction with oval defined by the flush surface.

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

10. The sensor port of claim 9, wherein the analyte meter is a glucose meter.

11. The sensor port of claim 10, wherein the analyte sensor is a glucose test strip.

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

13. The sensor port of claim 12, wherein the compliant gasket material comprises an elastomeric material.

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

15. The sensor port of claim 1, wherein a first edge of the entry slot comprises an internal beveled face.

16. The sensor port of claim 15, wherein a second edge of the entry slot does not comprise an internal beveled face.

17. The sensor port of claim 15, wherein a second and third edge of the entry slot each comprise an internal beveled face.

18. The sensor port of claim 15, wherein a second edge of the entry slot is curved and a third edge of the entry slot is curved and opposite the second edge.

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

20. 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.

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

22. The sensor port of claim 21, wherein the electrical device is an analyte meter.

23. The sensor port of claim 22, wherein the analyte meter is a glucose meter.

24. The sensor port of claim 21, wherein electrical device is an integrated continuous glucose monitor receiver.

25. The sensor port of claim 21, wherein the electrical device is a medication delivery device.

26. The sensor port of claim 25, wherein the medication delivery device is a pump.

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

28. 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.

29. The sensor port of claim 1, wherein the flush surface has the same shape as the first sealing member.

30. 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 extending from the body and having a distal end, wherein the distal end comprises an entry slot to receive an analyte sensor; and

a first sealing member circumscribing the protruding member and positioned wholly between the entry slot and the body of the housing, wherein the first sealing member forms a seal between the sensor port and the medication delivery device into which the sensor port is integrated.

31. The medication delivery device of claim 30, 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.

32. The medication delivery device of claim 31, wherein the second and third sealing members each comprise an adhesive backing which provides for attachment to the body of the housing.

33. The medication delivery device of claim 32, wherein the second and third sealing members each comprise polyimide film tape.

34. The medication delivery device of claim 30, wherein the protruding member comprises a channel which circumscribes the protruding member, and wherein the first sealing member is positioned in the channel.

35. The medication delivery device of claim 34, wherein the channel defines an oval.

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

37. The medication delivery device of claim 30, wherein the first sealing member is a compliant gasket material.
