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. An analyte meter and sensor port, comprising:

the sensor port integratable and connectable to the analyte meter and including 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,

wherein the first sealing member forms a seal between the sensor port and the analyte meter.

2. The analyte meter and 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 such that a seal is formed over the first opening; and

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

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

5. The analyte meter and sensor port of claim 1, wherein a channel which circumscribes the protruding member between the entry slot and the body, and wherein the first sealing member is positioned in the channel.

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

7. The analyte meter and sensor port of claim 6, wherein the distal end comprising the entry slot is a flush surface and defines an oval.

8. The analyte meter and sensor port of claim 1, wherein the analyte meter is a glucose meter.

9. The analyte meter and sensor port of claim 1, wherein the first sealing member is a compliant gasket material.

10. The analyte meter and sensor port of claim 9, wherein the compliant gasket material comprises an elastomeric material.

11. The analyte meter and sensor port of claim 9, wherein the compliant gasket material is an o-ring.

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

13. The analyte meter and sensor port of claim 12, 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.

14. The analyte meter and sensor port of claim 12, wherein a second edge of the entry slot does not comprise an internal beveled face.

15. The analyte meter and sensor port of claim 12, wherein a second and third edge of the entry slot each comprise an internal beveled face.

16. The analyte meter and sensor port of claim 1, wherein the distal end comprising the entry slot is a flush surface and has the same shape as the first sealing member.

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

18. The analyte meter and sensor port of claim 1, wherein the sensor port is integrated in and operably connected to the analyte meter.

19. The analyte meter and sensor port of claim 1, wherein the first sealing member provides a substantially fluid-tight seal between the sensor port and the analyte meter.
