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 replaceable sensor port for use with an analyte meter, comprising:

a housing comprising a top portion and a bottom portion, wherein the top portion and bottom portion are joined to form a body and a protruding member of the housing;

an entry slot formed by the top and bottom portions to receive an analyte sensor and comprising a first edge having an internal beveled face to prevent ingress of external contaminants through the entry slot when an analyte sensor is received within the entry slot, and a second edge without an internal beveled face, wherein the second edge is in opposite and facing configuration with the first edge;

an electrical interface disposed within an internal opening in the body of the housing, wherein the electrical interface is electrically coupled to an analyte sensor when the sensor is received within the entry slot;

a first sealing member extending around the protruding member and positioned wholly between the entry slot and the body of the housing, wherein the first sealing member provides a seal between the sensor port and an analyte meter into which the sensor port is integrated when the sensor port is coupled to the analyte meter; and

a plurality of electrical contacts extending from an exterior surface of the housing to electrically couple with the analyte meter.

2. The replaceable sensor port of claim 1, further comprising a second sealing member disposed between the plurality of electrical contacts and the exterior surface of the housing extending around an edge of the body of the housing.

3. The replaceable sensor port of claim 1, wherein the first sealing member is an oval shape, or an elliptical shape.

4. The replaceable sensor port of claim 1, wherein the analyte sensor is a glucose test strip or a ketone test strip.

5. The replaceable sensor port of claim 1, wherein the entry slot further comprises a third edge having an internal beveled face and a fourth edge having an internal beveled face.

6. The replaceable sensor port of claim 1, wherein the distal end of the protruding member comprises a single flush surface.

7. The replaceable sensor port of claim 6, wherein the single flush surface has the same shape as the first sealing member.

8. The replaceable sensor port of claim 6, wherein the entry slot further comprises a third edge and a fourth edge in an opposite and facing configuration with the third edge, and wherein the single flush surface comprises the first edge, second edge, third edge and fourth edge.

9. The replaceable sensor port of claim 1, wherein the distal end of the protruding member defines a periphery having an elliptical shape.

10. The replaceable sensor port of claim 1, wherein the entry slot further comprises a third edge that is curved and a fourth edge that is curved and on an opposite side of the entry slot than the third edge.

11. The replaceable sensor port of claim 1, wherein the entry slot comprises a flush surface about the circumference of the entry slot.

12. A replaceable sensor port for use with an analyte meter, comprising:

a housing comprising a top portion and a bottom portion, wherein the top portion and bottom portion are joined to form a body and a protruding member of the housing;

an entry slot formed by the top and bottom portions and providing access to an internal region of the body of the housing and comprising a first edge having an internal beveled face to prevent ingress of external contaminants through the entry slot when an analyte sensor is received within the entry slot, and a second edge without an internal beveled face, wherein the second edge is in opposite and facing configuration with the first edge;

a first sealing member extending around the protruding member and positioned wholly between the entry slot and the body of the housing, wherein the first sealing member provides a seal between the sensor port and an analyte meter into which the sensor port is integrated when the sensor port is coupled to the analyte meter;

internal electrical contacts disposed within the internal region of the body of the housing, wherein said electrical contacts operably couple to an analyte sensor received within the internal region of the body of the housing; and

external electrical contacts extending from the body of the housing and electrically coupled to the internal electrical contacts, wherein the external electrical contacts operably connect to the analyte meter.

13. The replaceable sensor port of claim 12, further comprising a second sealing member disposed between the external electrical contacts and the body of the housing.

14. The replaceable sensor port of claim 12, wherein the first sealing member is an oval shape, or an elliptical shape.

15. The replaceable sensor port of claim 12, wherein the analyte sensor is a glucose test strip or a ketone test strip.

16. A replaceable port for use in an analyte meter, comprising:

a body comprising a top portion and a bottom portion, wherein the body includes an internal opening;

a protruding member extending from the body, wherein the protruding member includes an entry slot formed by the top and bottom portions that provides access to the internal opening of the body, and wherein the entry slot is sized to receive an analyte test strip and comprises a first edge having an internal beveled face to prevent ingress of external contaminants through the entry slot when an analyte sensor is received within the entry slot, and a second edge without an internal beveled face, wherein the second edge is in opposite and facing configuration with the first edge;

a first sealing member extending around an the protruding member and positioned wholly between the entry slot and the body, wherein the first sealing member provides a seal between the sensor port and an analyte meter into which the sensor port is integrated when the sensor port is coupled to the analyte meter;

internal electrical leads disposed within the body, wherein said internal electrical leads operably couple to the analyte test strip received through the entry slot; and

external electrical leads extending from the body and electrically coupled to the internal electrical leads, wherein the external electrical leads operably couple to an analyte meter.

17. The replaceable port of claim 16, further comprising a second sealing member disposed between the external electrical leads and the body.

18. The replaceable port of claim 17, wherein the analyte test strip is a glucose test strip or a ketone test strip.
