Electrode for biological detection test specimen, manufacturing method thereof and biological detection test specimen thereof

Abstract

The invention discloses an electrode for biological detection test specimens, a manufacturing method thereof and a biological detection test specimen thereof. The electrode comprises a flexible insulating layer, a resin layer, a first metal layer, a second metal layer, a third metal layer and a fourth metal layer, wherein the resin layer is adsorbed on the flexible insulating layer; the first metal layer, the second metal layer, the third metal layer and the fourth metal layer are sequentially arranged on the resin layer; the material of the first metal layer comprises copper foil, brass, clinquant (Tombac), phosphor bronze, nickel, silver or other combinations; the material of the second metal layer comprises palladium; the material of the third metal layer comprises nickel; and the material of the fourth metal layer comprises palladium or gold. In the invention, the measurement data of the electrode is exact; the power can be saved; the cost can be reduced; the biological detection test specimen can help the diabetes patients, the hypercholesterolemia patients or gout patients to measure the data such as blood sugar, cholesterol or uric acid and the like more exactly.

Description

technical field [0001] The present invention relates to an electrode and its test piece, in particular to an electrode used for a biological detection test piece, its manufacturing method and its biological detection test piece. Background technique [0002] The current detection and diagnosis technology industry refers to detection and diagnosis products used to collect, process, inspect and analyze specimens, including reagents and related drugs, necessary equipment, systems and other related auxiliary instruments. Most of the general diagnostic reagents are used in vitro, and the samples may be animal urine, feces, blood, saliva, other body fluids or tissue fluid of plants. For the domestic market, the main products are mainly medical tests, including blood sugar or uric acid test strips, hepatitis B or C hepatitis test reagents, HIV test reagents, pregnancy test reagents, enterovirus tests, hypercholesterolemia, hypertriglyceridemia Syndrome or urine enzyme immunoassay,...

AI Technical Summary

Problems solved by technology

[0005] (1) The production batch is unstable, and there is a defective rate of about 10%-20%, which increases the cost

[0006] (2) Due to the printing process technology of each electrode, it is impossible to effectively control the stability of its impedance value, resulting in a large coefficient of variation (CV value)

[0007] (3) Poor test accuracy

[0008] (4) Calibration with a calibration card (Code Card) is required before the test, causing inconvenience for users and increasing costs

[0009] (5) Carbon (C) electrode characteristics consume power supply and increase cost due to high impedance value
