Abstract

Method and system for providing analyte sensor alignment and retention mechanism for improved connectivity with a transmitter unit for electrical connection, and further including transmitter unit contact pins with metal components to improve electrical conductivity with the analyte sensor in an analyte monitoring and management system is provided.

First claim

What is claimed is:

1. An assembly comprising:
a sensor subassembly comprising an analyte sensor and a sensor seal, wherein the analyte sensor comprises a first portion configured to be electrically coupled with a transmitter and a second portion configured to be inserted through a skin surface and in fluid contact with a bodily fluid of a user;
a transmitter mount comprising a base and a locking mechanism; and
an insertion mechanism configured to position the sensor subassembly against the base of the transmitter mount by causing movement of the sensor subassembly until the locking mechanism engages the sensor subassembly, wherein the movement of the sensor subassembly is impeded while the locking mechanism is engaged;
wherein the assembly is configured to be applied to the skin surface of the user,
wherein the insertion mechanism is further configured to be removed from the transmitter mount after the second portion of the analyte sensor is inserted through the skin surface and in fluid contact with the bodily fluid of the user, and
wherein the transmitter mount is configured to receive a transmitter after the locking mechanism is engaged and the insertion mechanism is removed from the transmitter mount.

2. The assembly of claim 1 , wherein the insertion mechanism is further configured to position the second portion of the analyte sensor through the skin surface and in fluid contact with the bodily fluid.

3. The assembly of claim 1 , wherein the sensor seal includes a plurality of radial seal holes disposed on the sensor seal, and wherein each of the radial seal holes is configured to receive one of a plurality of electrical contacts.

4. The assembly of claim 1 , wherein the transmitter mount further comprises an opening to detachably couple to the transmitter.

5. The assembly of claim 1 , wherein the insertion mechanism is further configured to position the sensor subassembly in the transmitter mount from a first position to a second position, wherein in the second position, the first portion of the analyte sensor and the sensor seal are secured against the base of the transmitter mount by the locking mechanism before the transmitter is received in the transmitter mount.

6. The assembly of claim 1 , wherein the analyte sensor includes a plurality of conductive contacts and the transmitter includes a plurality of electrical contacts, and wherein each of the plurality of electrical contacts aligns with a respective one of the conductive contacts when the transmitter is coupled to the transmitter mount.

7. The assembly of claim 6 , wherein a contact point between each of the plurality of electrical contacts and the respective one of the plurality of conductive contacts includes a conductive polymer.

8. The assembly of claim 6 , wherein each of the plurality of electrical contacts includes a metal component disposed therein, wherein at least a first end of each of the plurality of electrical contacts is configured to substantially contact the respective one of the plurality of conductive contacts of the analyte sensor.

9. The assembly of claim 1 , wherein the transmitter is configured to transmit sensor data to a receiver unit via a bi-directional radio frequency (RF) communication path.

10. The assembly of claim 1 , wherein the transmitter is configured to transmit sensor data to a receiver unit via a Bluetooth communication link.

11. The assembly of claim 1 , further comprising an adhesive layer configured to secure the transmitter mount to the skin surface of the user.

12. The assembly of claim 11 , wherein the insertion mechanism is configured to position the sensor subassembly in the transmitter mount while the transmitter mount is secured to the skin surface of the user by the adhesive layer.

13. The assembly of claim 1 , wherein the transmitter is configured to transmit predetermined transmitter identification information to a receiver unit.

14. The assembly of claim 1 , wherein the analyte sensor comprises a glucose sensor.

15. The assembly of claim 1 , wherein the locking mechanism comprises two protrusions configured to secure the sensor subassembly to the base of the transmitter mount before the transmitter is received in the transmitter mount.

16. The assembly of claim 15 , wherein the two protrusions of the locking mechanism comprise two latches each of which is configured to mate with a corresponding opening.

17. The assembly of claim 15 , wherein the two protrusions of the locking mechanism comprise a molded plastic material.

18. The assembly of claim 15 , wherein the two protrusions of the locking mechanism comprise two clip portions each of which is disposed on a retaining segment.
