Method for preparing planar bioinstrumentation test block and finished product of planar bioinstrumentation test block

Abstract

The invention provides a method for preparing a planar bioinstrumentation test block and a finished product of the planar bioinstrumentation test block. The test block comprises a slide and a ferment reaction area, wherein a conductive path formed by evaporation is arranged on the slide; a detection electrode end and an electrode line end which are conducted are arranged at the front end and the rear end of the conductive path; and the ferment reaction area is connected with the front end of the detection electrode end. The method for preparing the planar bioinstrumentation test block comprises the following steps of: (1) constructing a shield image printed line in a printing manner by using a plastic thin film as the slide; (2) forming a conductive plated layer by evaporating the slide printed with the shield image printed line; (3) physically removing the conductive plated layer block covered by the shield image printed line and displaying the conductive path; (4) placing ferment into the ferment reaction area; and (5) attaching an upper cover film; therefore, the test block has economic benefits of mass production and reduction of cost, so that the quality stability and the market competitiveness of products can be improved.

Description

Technical field [0001] The present invention relates to a method for preparing a flat biological detection test strip and its products, in particular to a test strip for detecting physiological conditions of biological fluids, such as detecting blood sugar, cholesterol or urine in human blood, etc., in detail , Its finished product has better stability, accuracy, and is very economical in preparation. Background technique [0002] According to the theory, the general extension of modern people's life expectancy is closely related to the development of modern medical technology. Many latent symptoms can be confirmed through the preliminary inspection of medical equipment, and thus achieve the effect of early prevention and treatment. Take the detection of human blood sugar as an example. First, a small amount of blood is collected from the human body, and then the blood is dripped into the blood glucose enzyme area on the reaction test strip for reaction, and then analyzed by a bl...

Problems solved by technology

[0006] 1. It is based on a single-sheet plastic film 100, and then forms the front-stage detection electrode terminal 931 and the rear-stage electrode line terminal 932 on the substrate by screen printing carbon ink, because the detection electrode terminal 931 And the length of the electrode line terminal 932 is longer and the surface area is larger, so it is more unstable during processing, and it is easy to cause the phenomenon of uneven resistance value;

[0007] 2. In order to reduce the above unstable conditions, at present, a conductive silver ink is mostly printed on the carbon ink layer base, which can improve its stability, but due to the high cost of silver ink materials, and the thickness control requirements and drying process during printing Complexity also has many deficiencies;

[0011] Therefore, in view of the unsatisfactory fact that the production of the existing planar biological detection test piece and its preparation method are not ideal, the inventors set out to develop its solution, hoping to develop a more accurate, stable and economical method. In order to serve the general public and promote the development of this industry, the present invention came into existence after a long time of conception.
