Problems solved by technology

However, this method adopts multi-layer screen printing technology, and needs to use screen printing inks of different properties to print on the same substrate, resulting in a complicated silk screen manufacturing process, which brings certain difficulties to the post-processing and packaging of test paper, and is not conducive to large-scale production.

Embodiment 1

[0020] Embodiment 1: Polyethylene (PVC) sheet material, cut into 150X150 centimeter substrate in advance for subsequent use.

[0021] (1) Add 1.2% hydroxyethyl cellulose and 10% benzoquinone, an electronically conductive carrier material, to 1 gram of silk-screen conductive carbon ink (Acheson 423 SS), mix well and set aside.

[0022] (2) Fix the 200-mesh metal or nylon polyester wire mesh on the square light metal frame, apply Kodak photosensitive glue in the dark room, and dry it for later use.

[0023] (3) Place the computer-drawn negatives of the working electrode and the reference electrode on the photosensitive adhesive, and expose them to a 20-watt ultraviolet lamp for 15 minutes. Rinse off the unhardened photosensitive adhesive covered by the electrode negative with a high-pressure water gun. After drying, a screen printing template is formed.

[0024] (4) Install the screen printing template with the working electrode and reference electrode graphics on the (DEK-245...

Embodiment 2

[0029] Embodiment 2: polyester (PET) sheet material, cut into 150 * 150 centimeter substrates in advance for subsequent use.

[0030] (1) Add 1.8% hydroxyethyl cellulose and 15% benzoquinone, an electron-conductive carrier material, to the silk-screen conductive carbon ink (Acheson 423 SS), mix well and set aside.

[0031] (2) Fix the 300-mesh metal or nylon polyester wire mesh on a square light metal frame, apply Kodak photosensitive glue in the dark room, and dry it for later use.

[0032] (3) Place the computer-drawn negatives of the working electrode and the reference electrode on the photosensitive adhesive, and expose them to light for 25 minutes under a 20-watt ultraviolet lamp. Rinse off the unhardened photosensitive adhesive covered by the electrode negative with a high-pressure water gun. After drying, a screen printing template is formed.

Abstract

Blood sugar test device accessory test paper is to print working electrode, reference electrode and electric circuit on base plate printed with guide line connecting with read-out meter on one end, the working and the reference electrodes are printed on carbon coating formed on the base plate conductive silver layer, biological enzyme, medium and adhesive are sprayed on the working electrode. Combining silk screen and spary printing the test paper is process and silk screening is limitted on printing conductive circuit, separating sensitive biologic element, from the silk material to print on electrode supporter by uncontacting spray controlled by computer.

Description

technical field [0001] The invention relates to a test paper and a manufacturing method thereof, in particular to a blood glucose tester matching test paper and a manufacturing method thereof, belonging to the technical field of biosensing. Background technique [0002] According to statistics, there are more than 40 million diabetic patients in my country, and the number is increasing at a rate of 1.5% every year. One of the effective means to control the development of diabetes is to implement blood sugar testing to strictly control medication and diet, and maintain the stability of the patient's blood sugar index. At present, some blood glucose meters on the market use composite screen printing technology for supporting test strips. The production process of this kind of blood glucose test strip is complicated, requires special materials, and the cost and scrap rate are high, so it is difficult to realize industrialization in China. It is found through literature review ...
