Abstract

Method and apparatus for providing an integrated transmitter unit and sensor insertion mechanism is provided.

Claims

1. A system, comprising:

an integrated housing having electronics including a transmitter unit and a sensor;

the integrated housing configured for mounting onto a skin of a patient; and

a sensor introducer assembly mounted onto the integrated housing, the introducer assembly configured to position at least a portion of the sensor under the skin of the patient;

wherein the transmitter unit is coupled to and in electrical contact with the sensor, and configured to transmit one or more signals corresponding a respective one or more signals received from the sensor;

wherein a portion of the electronics is configured to be selectively disabled after a predetermined time period has elapsed since coupling to the sensor;

wherein the integrated housing further comprises at least one sensor insertion location for extending the portion of the sensor therethrough; and

further

wherein the integrated housing further comprises a plurality of sensor insertion locations.

2. The system of claim 1 further including a receiver unit configured to receive the one or more signals transmitted by the transmitter unit.

3. The system of claim 2 wherein the receiver unit includes one of an infusion pump, a monitoring device, a personal digital assistant, a pager, or a mobile telephone.

17. The system of claim 1 wherein the introducer assembly is configured to be removably detached from the integrated housing after the inserting at least the portion of the sensor.

18. The system of claim 1 wherein the one or more signals from the sensor substantially corresponds to a respective one or more analyte levels of the patient.

19. The system of claim 1 wherein the transmitter unit is configured to wirelessly transmit data corresponding to the one or more signals received from the sensor.

20. The system of claim 1 wherein the sensor is an analyte sensor.

21. The system of claim 20 wherein the analyte sensor is a glucose sensor.

22. The system of claim 1 wherein the predetermined time period comprises about 1 day or more.

4. A system, comprising:

a housing configured for mounting onto a skin of a patient and comprising at least one sensor insertion location therethrough;

a sensor having a portion configured to be positioned through the at least one sensor insertion location and then within the skin of a patient; and

a transmitter integrally provided within the housing, wherein the transmitter is electrically coupled to the sensor by an electrical connection within the housing extending between the transmitter and the at least one sensor insertion location when the sensor is operatively positioned within the skin and wherein the electrical connection is configured to be selectively disabled after a predetermined time period has elapsed since coupling to the sensor;

wherein the housing comprises a plurality of sensor insertion locations and a plurality electrical connections, and further wherein there is a one for one correlation between the locations and the number of electrical connections.

5. The system of claim 4 further comprising a sensor introducer configured to transcutaneously position at least a portion of the sensor within the skin of the patient.

6. The system of claim 5 wherein the introducer is configured to be removed from the system after insertion of the sensor within the skin.

7. The system of claim 5 wherein the introducer is configured to be substantially housed within the system after insertion of the sensor within the skin.

8. The system of claim 4 wherein the housing is flexible to substantially conform to the shape of a body portion to which it is mounted.

23. The system of claim 4 wherein the sensor is an analyte sensor.

24. The system of claim 23 wherein the analyte sensor is a glucose sensor.

25. The system of claim 4 wherein the predetermined time period comprises about 1 day or more.

9. A method, comprising:

securing a housing substantially around a body part of a patient, the housing comprising an integrated electronics including a transmitter unit and a plurality of sensor insertion apertures therethrough, wherein an electrical connection is provided between the electronics and each of the sensor insertion apertures;

inserting at least a portion of a sensor through a sensor insertion aperture and into the skin of the patient so that the portion of the sensor is in fluid contact with a biological fluid of the patient, and further wherein the sensor is in electrical contact with the transmitter unit;

transmitting data associated with the signals received from the sensor; and

disabling a portion of the electronics at the sensor insertion location through which the sensor has been inserted after a predetermined time period has elapsed since the sensor has been in electrical contact with the transmitter unit.

10. The method of claim 9 further comprising inserting a second sensor into a second sensor insertion location and into the skin of the patient, and disabling the electrical connection between the electronics and the second insertion location after the predetermined time period has elapsed.

11. The method of claim 10 further comprising inserting additional sensors individually within the other available sensor insertion locations, one at a time upon elapsing of the predetermined time period.

12. The method of claim 11 further comprising rendering the transmitter unit unusable after a predetermined number of uses.

13. The method of claim 12 wherein the predetermined number of uses corresponds to the number of sensor insertion locations.

14. The method of claim 9 wherein the predetermined time period comprises about 1 day or more.

15. The method of claim 9 wherein the inserting at least the portion of the sensor is performed manually.

16. The method of claim 9 wherein the inserting at least the portion of the sensor comprises using an automated mechanism.
