Embodiment Construction

[0020] In order to make the technical solution of the present invention clearer, the following is combined with the appendix figure 1 and 2 , the present invention will be described in detail. It should be understood that the specific embodiments described in this specification are only for explaining the present invention, but not for limiting the protection scope of the present invention.

[0021] The present invention is a manufacturing method of a double-sided hydrophilic film. The double-sided hydrophilic film includes a substrate 1, an upper hydrophilic film 2 is coated on the upper surface of the substrate 1, and a lower surface of the substrate 1 is coated. The lower layer hydrophilic film 3 is coated, the upper layer PE film 4 is compounded on the upper layer hydrophilic film 2, and the lower layer PE film 5 is compounded on the lower layer hydrophilic film 3. Preferably, the upper layer hydrophilic film 2. The lower hydrophilic film 3 is prepared by dissolving fatt...

Abstract

The invention discloses a preparation method of a bifacial hydrophilic film. The bifacial hydrophilic film comprises a substrate, wherein an upper-layer hydrophilic film is coated on the upper surfaceof the substrate, an upper-layer PE film is compounded on the upper-layer hydrophilic film, a lower-layer hydrophilic film is coated on the lower surface of the substrate, and a lower-layer PE film is compounded on the lower-layer hydrophilic film. The preparation method of the bifacial hydrophilic film comprises the following steps: 1, firstly coating the lower-layer hydrophilic film; 2, performing drying, and then, compounding the lower-layer PE film; 3, coating the upper-layer hydrophilic film; 4, performing low-temperature drying, and then, compounding the upper-layer PE film; and 5, performing cutting. The bifacial hydrophilic film disclosed by the invention can greatly improve the blood diffusion performance of the hydrophilic film of a blood glucose test strip so as to further improve the detection accuracy of blood glucose indexes.

Description

technical field [0001] The invention relates to a manufacturing method of a double-sided hydrophilic film. Background technique [0002] In rapid blood glucose diagnostic testing, blood glucose test strips have been widely used. In blood glucose test strips, in addition to oxidoreductases and conductive media, the factors that affect the detection accuracy are hydrophilic membranes. When the blood sample to be tested is dropped on the blood glucose test strip, the hydrophilic membrane can quickly spread the blood drop and suck it into the working area of ​​the electrode to ensure the blood glucose detection. [0003] In order to improve the detection accuracy of the blood glucose test strip, the diffusion performance of the hydrophilic membrane can only be improved when the oxidoreductase and the conductive medium have been determined. How to improve the performance of the hydrophilic membrane of blood glucose test strips is an important topic for those skilled in the art....
