Abstract

The invention includes a base, a working wire, a grounding wire, a first division layer, a second division layer and a cover layer. The base has a reaction area. The working wire is formed with a first measure contact and a first bioreaction contact. The grounding wire is formed with a second measure contact and a second bioreaction contact. The first division layer and second division layer have a first inlet and a second inlet, respectively. The first inlet and the second inlet correspond to the reaction area in position to expose the first and second bioreaction contacts. The guiding trough is formed by the cover layer, the base and the first and second inlets.

Claims

1. A test strip comprising:

a base, having a reaction area;

a working wire, formed on the base, two ends thereof being separately formed with a first measure contact and a first bioreaction contact, and the first bioreaction contact extending into the reaction area;

a grounding wire, formed on the base, parallel to the working wire, two ends thereof being separately formed with a second measure contact and a second bioreaction contact, and the second bioreaction contact extending into the reaction area;

a first division layer having a first inlet, wherein the first inlet is formed by indenting a portion of one linear edge of the first division layer;

a second division layer, being a single piece without any separation, having a second inlet, superposed on the first division layer, overlapped with the working wire and the grounding wire, and being provided with an air passage trough directly communicating and connecting with the second inlet, wherein the second inlet is formed by indenting a portion of one linear edge of the second division layer, the first inlet and the second inlet correspond to the reaction area in position to expose the first and second bioreaction contacts, and the air passage trough is a bottomed recess; and

a cover layer, attached on the second division layer, and completely cloaking one side of the second division layer, wherein a guiding trough is formed by the cover layer, the base and the first and second inlets;

wherein the reaction area is coated with a bioreaction film, the air passage trough is perpendicular to the second inlet, a disconnected wire is disposed on the base, two ends of a sample detection wire are separately formed with a third measure contact and a third bioreaction contact extending into the reaction area, an adhesive layer is disposed between the first division layer and the base, the adhesive layer is formed with a recess corresponding to the first inlet, and the adhesive layer is made of polyethylene terephthalate (PET), and an end of the code wire is formed with a plurality of fourth measure contacts.

2. The test strip of claim 1, wherein the code wire is composed of two parallel lines.

3. The test strip of claim 1, wherein the code wire further comprises at least one node.

4. The test strip of claim 3, wherein the code wire further comprises two or more nodes.
