Abstract

The present disclosure provides a sensor port configured to receive a plurality of analyte sensors having different sizes, shapes and/or electrode configurations. Also provided are analyte meters, analyte monitoring devices and/or systems and drug delivery devices and/or systems utilizing the disclosed sensor ports.

Claims

1. A method of determining the concentration of an analyte in a biological sample, comprising:

inserting an analyte sensor in a sensor port of an analyte monitoring device, the sensor port comprising;

a first set of contacts positioned along a top portion and a bottom portion of the sensor port for contacting a first analyte sensor having an opposing electrode contact configuration;

a second set of contacts positioned on the top portion or the bottom portion of the sensor port for contacting a second analyte sensor having a co-planar electrode contact configuration;

wherein the analyte monitoring device comprises a processor programmed to;

receive a signal indicative of the concentration of the analyte from the first set of contacts, and

receive a signal indicative of the concentration of the analyte from the second set of contacts; and

depositing the biological sample on the analyte sensor;

receiving, by the processor, the signal from either the first set of contacts or the second set of contacts; and

determining the concentration of the analyte in the biological sample based on the signal.

2. The method of claim 1, wherein the first analyte sensor is a glucose sensor and the second analyte sensor is a ketone sensor.

3. The method of claim 1, wherein both the first and second analyte sensors are glucose sensors.

4. The method of claim 1, further comprising a communication unit.

5. The method of claim 4, wherein the communication unit is configured to provide two-way communication between the sensor port and a device and/or network external to the sensor port.

6. The method of claim 4, wherein the communication unit is configured to provide two-way communication between the sensor port and a network external to the sensor port.

7. The method of claim 6, wherein the network is a computer network.

8. The method of claim 4, wherein the communication unit is configured to provide wireless communication between the sensor port and an external device.

9. The method of claim 8, wherein the external device is a medication delivery device or an implanted or partially implanted analyte sensor.

10. The method of claim 8, wherein the external device is an insulin pump.

11. The method of claim 4, wherein the communication unit comprises a Universal Serial Bus (USB) connector.

12. The method of claim 4, wherein the communication unit is configured to provide wireless communication between the sensor port and an external device and/or network.

13. The method of claim 12, wherein the communication unit utilizes a wireless communication protocol selected from a radio frequency (RF) protocol and an infrared (IR) protocol.

14. The method of claim 12, wherein the communication unit is configured to provide wireless communication between the sensor port and an external device, the external device comprises a Radio-Frequency Identification (RFID) tag, and the communication unit utilizes an RF wireless communication protocol to communicate with the Radio-Frequency Identification (RFID) tag.

15. The method of claim 12, wherein the communication unit utilizes a wireless communication protocol selected from code division multiple access (CDMA) and Global System for Mobile communications (GSM).

16. The method of claim 1, wherein the sensor port is configured to receive analyte sensors having different widths.

17. The method of claim 16, wherein the sensor port comprises a side wall and a biasing mechanism configured to position the analyte sensors against the sidewall during insertion of the analyte sensors.

18. The method of claim 16, wherein the first analyte sensor has a width which is greater than that of the second analyte sensor.

19. The method of claim 16, wherein the first analyte sensor has a width which is less than that of the second analyte sensor.

20. The method of claim 1, wherein the sensor port comprises an analyte sensor ejector slidably engaged therewith.

21. The method of claim 1, wherein the sensor port comprises at least four sensor port contacts configured to contact the first analyte sensor upon insertion of the first analyte sensor into the sensor port, and at least three sensor port contacts configured to contact the second analyte sensor upon insertion of the second analyte sensor into the sensor port.

22. The method of claim 21, wherein the sensor port comprises at least seven different sensor port contacts.

23. The method of claim 22, wherein the sensor port comprises at least nine different sensor port contacts.

24. The method of claim 21, wherein one of the at least four sensor port contacts is attached to the top portion of the sensor port and three of the at least four sensor port contacts are attached to the bottom portion of the sensor port.

25. The method of claim 21, wherein the at least three sensor port contacts are attached to the top portion of the sensor port.

26. The method of claim 21, wherein the sensor port comprises a protective protrusion extending from the top portion of the sensor port into the interior of the sensor port.
