Abstract

Method and apparatus for providing an integrated analyte sensor and data processing unit assembly is provided.

Claims

1. An apparatus, comprising:

a housing;

a data processing unit disposed in the housing;

an introducer disposed within the housing and including a portion having a sharp distal end configured for piercing a body of a subject, wherein the portion of the introducer is removable from the housing after piercing the body of the subject; and

an analyte sensor including a first portion and a second portion, the first portion of the analyte sensor at least partially disposed, prior to the removal of the introducer, within the portion of the introducer having the sharp distal end, and the second portion of the analyte sensor coupled to the data processing unit;

wherein the first portion of the analyte sensor is configured for positioning in fluid contact with a biological fluid in the subject, and the second portion of the analyte sensor is in electrical contact with the data processing unit prior to positioning of the first portion of the analyte sensor.

2. The apparatus of claim 1, further including an adhesive layer provided on a lower surface of the housing, wherein the adhesive layer is configured to removably attach the housing to the body of the subject.

3. The apparatus of claim 2, wherein the adhesive layer includes a removable protective layer.

4. The apparatus of claim 1, wherein the apparatus is configured such that when the sharp distal end pierces the body of the subject, the first portion of the analyte sensor is positioned in fluid contact with the biological fluid in the subject.

5. The apparatus of claim 1, wherein the introducer is configured to decouple from the data processing unit after the first portion of the analyte sensor is positioned in the body of the subject.

6. The apparatus of claim 1, wherein the data processing unit includes a data communication unit configured to receive one or more signals associated with a monitored analyte level from the analyte sensor.

7. The apparatus of claim 6, wherein the data communication unit is configured to wirelessly communicate data associated with the one or more signals received from the analyte sensor to a remote location.

8. The apparatus of claim 1, wherein the introducer is positioned through an aperture of the housing.

9. The apparatus of claim 1, wherein the second portion of the analyte sensor extends substantially transverse to the first portion of the analyte sensor.

10. An assembly, comprising:

a housing;

a data processing unit disposed within the housing;

an introducer disposed within the housing and including a portion having a sharp distal end configured for piercing a body of a subject, wherein the portion of the introducer is removable from the housing after piercing the body of the subject; and

an analyte sensor coupled to the housing, a first portion of the analyte sensor configured for positioning in fluid contact with a biological fluid in the subject, and a second portion of the analyte sensor disposed within the housing and in electrical communication with the data processing unit prior to positioning of the first portion of the analyte sensor;

wherein the first portion of the analyte sensor is at least partially disposed, prior to removal of the introducer, within the portion of the introducer having the sharp distal end; and

wherein the housing includes an aperture through which the introducer is removable.

11. The assembly of claim 10, wherein the second portion of the analyte sensor is permanently coupled to the data processing unit.

12. The assembly of claim 10, wherein the introducer is configured to decouple from the data processing unit after the first portion of the analyte sensor is positioned in the body of the subject.

13. The assembly of claim 10, wherein the data processing unit includes a data communication unit configured to receive one or more signals associated with a monitored analyte level from the analyte sensor.

14. The assembly of claim 13, wherein the data communication unit is configured to wirelessly transmit data associated with the one or more signals received from the analyte sensor.

15. The assembly of claim 10, further including an adhesive layer on a lower surface of the housing, wherein the adhesive layer is configured to removably attach the housing to the body of the subject.

16. The assembly of claim 10, wherein the introducer is positioned through the aperture of the housing.

17. The assembly of claim 10, wherein an opening in the data processing unit is configured to receive the portion of the introducer.

18. The assembly of claim 10, wherein the introducer further includes a proximal portion configured for engaging an outer surface of the data processing unit.
