Biological test strip with isolation structure
First Claim
1. A biological test strip with isolation structure, comprising:
- a substrate including a testing portion and a measuring portion;
an electrode disposed on the substrate and further including an operation electrode and an auxiliary electrode, the operation electrode provided with a first operating end disposed on the testing portion and a first reading end disposed on the measuring portion, the auxiliary electrode provided with a second operating end disposed on the testing portion and a second reading end disposed on the measuring portion;
a first flow confining member disposed on the measuring portion and surrounding the first operating end of the operation electrode; and
a second flow confining member disposed on the testing portion and further surrounding the first flow confining member and the second operating end of the auxiliary electrode, a height of the second flow confining member against the substrate is larger than a height of the first flow confining member against the substrate.

Abstract
A biological test strip with isolation structure includes a substrate having a testing portion and a measuring portion; an electrode disposed on the substrate and including an operation electrode and an auxiliary electrode, the operation electrode having a first operating end and a first reading end, the auxiliary electrode having a second operating end and a second reading end; a first flow confining member surrounding the first operating end; and a second flow confining member surrounding the first flow confining member and the second operating end, with a height of the second flow confining member larger than a height of the first flow confining member. Therefore, the flowing scope of the dropped liquid is confined, so as to fix the square measure of the dropped liquid contacting the electrode and thereby improve the analysis repeatability.
