Test sensor with a side vent and method of making the same
First Claim
1. A test sensor adapted to assist in determining the concentration of an analyte in a fluid sample, the test sensor comprising:
- a lid having an upper lid surface and a lower lid surface;
a base having an upper base surface and a lower base surface; and
a spacer having at least a first spacer section and a second spacer section, the first spacer section having a first spacer side and a first spacer end, the second spacer section having a second spacer side and a second spacer end,wherein the lid, base and spacer are attached such that a fluid chamber is formed between a portion of the lower lid surface and the upper base surface, and between the first and second spacer sides,wherein the lower lid surface, the upper base surface, the first spacer end and the second spacer end form at least one side vent therebetween, the at least one vent being in communication with the fluid chamber.

Abstract
A test sensor assisting in determining an analyte concentration in a fluid sample comprises a lid, a base and a spacer. The spacer has first and second spacer sections. The first spacer section has a first spacer side and a first spacer end. The second spacer section has a second spacer side and a second spacer end. The lid, base and spacer are attached such that a fluid chamber is formed between a portion of a lower lid surface and an upper base surface, and between the first and second spacer sides. The lower lid surface, the upper base surface, the first spacer end and the second spacer end form a side vent therebetween that is in communication with the fluid chamber.
