Abstract

In some aspects, an analyte sensor is provided for detecting an analyte concentration level in a biological fluid sample. The analyte sensor has a base including a top and bottom side, a lid, and an attachment member including one or more retention tabs coupled proximate the top side so that the analyte sensor can be grasped by the sensor'"'"'s top side. Manufacturing methods and systems adapted to use and dispense the analyte sensors are provided, as are numerous other aspects.

Claims

1. An analyte testing system, comprising:

an analyte meter including a pylon having grasping tabs; and

an analyte sensor including a base with a top side, a lid proximate the base on the top side, and an attachment member proximate the top side, the attachment member including a tab spacer and one or more retention tabs that form at least a grasping recess between the tab spacer and the one or more retention tabs, wherein the grasping recess is adapted to engage with the grasping tabs to secure the analyte sensor to the pylon.

2. The analyte testing system of claim 1, further comprising electrical connectors on the pylon adapted to contact electrical contact pads provided on a same side of the base as the attachment member.

3. The analyte testing system of claim 1, wherein the grasping tabs are moveable to release the attachment member.

4. The analyte testing system of claim 3, comprising a user-operable mechanism adapted to initiate movement of the grasping tabs.

5. The analyte testing system of claim 1, wherein the lid of the analyte sensor comprises the attachment member.

6. The analyte testing system of claim 1, wherein the attachment member is attached to a top side of the lid and the retention tabs extend along the top side of the lid.

7. The analyte testing system of claim 1, wherein the one or more retention tabs include a first retention tab extending in a first direction and a second retention tab extending in a second direction opposite the first direction.

8. The analyte testing system of claim 7, wherein the analyte sensor includes a hydrophobic layer on a bottom side of the base and a hydrophilic layer on a bottom side of the lid.

9. The analyte testing system of claim 1, wherein the one or more retention tabs form a first grasping recess and a second grasping recess adapted to receive the grasping tabs of the pylon of the analyte meter.

10. The analyte testing system of claim 9, wherein the first grasping recess is formed between the lid, the tab spacer, and a first retention tab and the second grasping recess is formed between the lid, the tab spacer, and a second retention tab of the attachment member.

11. The analyte testing system of claim 1, wherein the analyte sensor further includes electrical contact pads formed on the top side of the base.

12. The analyte testing system of claim 1 wherein the analyte sensor further includes a first channel spacer and a second channel spacer provided on either side of a fluid-receiving channel between the base and the lid.

13. The analyte testing system of claim 12 wherein the analyte sensor further includes a vent formed by surfaces of the lid, the first channel spacer, the second channel spacer, and the base.

14. The analyte testing system of claim 13 wherein the analyte sensor further includes at least one electrical conductor extending through the vent.

15. The analyte testing system of claim 1 wherein the analyte sensor further includes a vent and at least one electrical conductor extending through the vent.

16. A method of manufacturing an analyte testing system, comprising:

providing an analyte meter including a pylon having grasping tabs; and

providing an analyte sensor including a base with a top side, a lid proximate the base on the top side, and an attachment member proximate the top side, the attachment member including a tab spacer and one or more retention tabs that form at least a grasping recess between the tab spacer and the one or more retention tabs, wherein the grasping recess is adapted to engage with the grasping tabs to secure the analyte sensor to the pylon.

17. The method of claim 16, further comprising providing electrical connectors on the pylon adapted to contact electrical contact pads provided on a same side of the base as the attachment member.

18. The method of claim 16, wherein providing the analyte sensor includes providing grasping tabs that are moveable to release the attachment member.

19. The analyte testing system of claim 18, further comprising providing a user-operable mechanism adapted to initiate movement of the grasping tabs.
