Problems solved by technology

However, the above-mentioned light-tight design will cause the user to be unable to visually judge whether the collected amount of the test liquid is sufficient, whether the test liquid has filled the reaction chamber, and whether the test piece has been used. Therefore, the above test Chips often need to use an additional electrode layer to detect the above situation, but this will further cause the detection time of the test chip to be too long and the circuit design increases the detection items, so the problem of complexity and power consumption

Embodiment Construction

[0046] Please refer to figure 1 and figure 2 , figure 1 It is a three-dimensional schematic diagram of a test piece 10 proposed according to an embodiment of the present invention, figure 2 for figure 1 Schematic diagram of the explosion of the test piece 10. The test strip 10 can be used in the detection of blood glucose, cholesterol or physiological state and other drugs, such as figure 1 and figure 2 As shown, the test piece 10 includes a separator 12 , a substrate 14 , a cover 16 , a pad 18 , a reagent layer 24 , and an electrode layer 26 . The partition 12 has a recess 20 . The separator 12 and the cover sheet 16 can preferably be made of plastic material (such as polyethylene terephthalate (polyethylene terephthalate, PET) or polyethylene naphthalate (polyethylene naphthalate, PEN), etc.), The substrate 14 can be an insulating substrate made of common insulating materials (such as polyethylene terephthalate, etc.), the spacer 12 is bonded on the substrate 14 an...

Abstract

A test strip includes a substrate, a spacer layer having a notch, a reagent layer, a support layer, and a cover layer having a covering portion covering the notch and a channel portion extending rearward from the covering portion. The substrate is attached under the spacer layer. The support layer is connected to the cover layer and the spacer layer to make the channel portion away from the spacer layer at a vertical distance. The support layer, the covering portion, the notch, and the substrate form a reaction chamber for allowing an analyte solution to react with the reagent layer, and the support layer, the channel portion, and the spacer layer forms a channel for exhausting air.

Description

technical field [0001] The invention relates to a test piece, in particular to a test piece which utilizes an exhaust flow channel formed by the gasket, the exhaust channel part of the cover sheet and the partition to discharge the air in the reaction chamber backward. Background technique [0002] Generally speaking, the common test strips used to detect the test liquid can be roughly divided into two types: chemical (or biochemical) color test strips that do not require electrode electrical sensing components and biochemical identification components and electronic signal converters. inductance test piece. As far as the inductance test piece is concerned, when the test liquid is confirmed by the identification component, the chemical signal is converted into an electronic physical signal by an electronic signal converter, that is, an electrical reaction, and then after logical operation analysis, the quantitative digital signal Converted to the detected concentration of t...
