Test sheet

Abstract

This invention provides a test plate for biochemical test including: a chip carrying electrodes, a reaction region, a diversion film, a cover plate and a separation film, in which the reaction region is coated with a reacting reagent and connected with the electrode, which outputs electric signals by the lead, the diversion film is set on the chip, part of which end-the reaction region is covered by the cover plate and part of the other end is covered by the separation film, part of the diversion film covered by the cover plate between the chip and the cover plate forms a reaction cavity and a separation cavity is formed by the diversion film covered by the separation film between the chip and the separation film, the two cavities are connected by a feeding channel, the being tested solution enters into the separation cavity via the separated reaction solution and enters into the reaction cavity via the feeding channel to be reacted with the reaction reagent in the reaction region under the reaction cavity.

Description

technical field [0001] The invention relates to the field of electrochemical measurement, in particular to a test piece for biological and chemical measurement. Background technique [0002] Recent studies have shown that the increase of cholesterol in human blood is the main culprit of heart disease, myocardial infarction and cardiovascular disease. For example, hyperlipidemia is an important factor leading to hypertension and atherosclerosis, and the lipid index in the blood mainly refers to the comprehensive index of triglyceride and total cholesterol. With changes in diet, living habits, work pressure, etc., more and more patients have cardiovascular diseases caused by increased blood lipid concentration. Therefore, it is necessary for people to carry out cholesterol and triglyceride tests in time. Through timely monitoring and understanding of the concentration of cholesterol, etc., the cholesterol intake in the diet can be controlled in a timely manner, or physical ex...

Problems solved by technology

For the method of dropping liquid, measurement errors are often caused by the difficulty in accurately controlling the amount of liquid added, and the exposed or screen-covered reaction area is also easily polluted and affects the measurement results; the traditional suction from the side The test piece from the liquid to the reaction area is prone to the problem of poor exhaust effect

Therefore, how to overcome the problems of indeterminacy of the liquid to be measured, easy contamination of the reaction zone, and poor exhaust performance at the same time remains to be solved.
