Embodiment Construction

[0008] The following examples are provided in conjunction with the content of the method of the present invention to further illustrate the present invention.

[0009] Material

[0010] The above-mentioned test paper is produced by combining screen printing and spray printing. Screen printing is limited to printing conductive lines, and the spraying amount and spraying area are completely controlled precisely by a computer. Place the prepared test strip in the supporting tester and apply a working voltage of 220mV to the two sections of the working electrode and the reference electrode to measure different concentrations of lactic acid. The results show that the reaction occurs after 10 seconds, showing good test repeatability of the fabricated electrode. and relevance. Compared with the biochemical analyzer, 50 lactic acid quality control solutions and 50 patient blood samples were taken for lactic acid control test, and the correlation γ reached 0.9567. The relati...

Abstract

The enzyme electrode test strip belongs to the field of bio-sensing technology, on the base sheet of test strip a working electrode, a reference electrode, an electric circuit and a conductor connected with reading apparatus, on the working electrode and reference electrode the reaction working liquor can be spray-coated, and the composition of said reaction working liquor includes (wt%) 0.8-1.2%of enzyme, 15-25% of conductive medium, 5-15% of adhesive and 60-80% of buffer agent. If said invented test strip is contacted with body fluid of human body, the tested result can be directly displayed on the correspondent matched apparatus.

Description

technical field [0001] The invention relates to an enzyme electrode test paper, in particular to an enzyme electrode test paper for a human body fluid tester for measuring blood glucose, and belongs to the technical field of biosensing. Background technique [0002] With the rapid development of modern bioanalytical testing technology, a class of small mobile and portable testing instruments or testing methods suitable for patients' real-time self-control and quickly obtaining accurate test results, which is called POCT (Point of Care Testing) abroad, is developing rapidly. . Since this type of tester or test means involves multiple technical fields, the production of test papers matching these testers or test means includes relatively high technical content. Take the test strips for blood glucose meters as an example. Currently, the commercially available blood glucose test strips all adopt complicated manufacturing techniques, require the use of silk screen printing inks ...
