Embodiment Construction

[0018] As shown in the figure: the medical analysis tester (such as biosensor) of the invention includes a sample testing chamber 10, the testing chamber includes a chip / test strip jack 11, a test strip support platform 12 and a heating element 13. The heating element can be heated to a preset temperature and maintained at a preset temperature, and its temperature range is from 25°C to 65°C, and the ideal temperature control range is 35-55°C. The temperature can be set and controlled is the key to ensure the accuracy and precision of test results, which is not available in all miniature biosensors and miniature bioanalytical instruments at present. The test strip shown here is in direct contact with the heated temperature control platform 12 .

[0019] The electronic component arrangement 14 on the electronic circuit board is used for analyzing and processing the test results. The electronic component arrangement 14 includes electronic electrode contact points, and these conta...

Abstract

The invention relates to a medical analytical tester with controllable testing temperature, which can work normally under any environment with the temperature not higher than 55 DEG C, and can improve testing speed, precision and accuracy, in particular to a medical analytical tester used for testing blood parameters comprising cholesterol, triglyceride, blood sugar, glycolated hemoglobin, lactic acid, uric acid, pH of blood, oxyhemoglobin, potassium ions, sodium ions, calcium ions, magnesium ions in blood, HCO3-, PO43-, oxygen partial pressure, CO2 partial pressure and other indexes. The tester comprises a micro sample working chamber for accommodating and fixing testing biochips or testing strips and testing, an electronic system which is organically connected with the working chamber and used for reading and outputting a testing result, a screen for displaying the testing result, and a heating element or a setting for controlling the temperature of a tested sample.

Description

technical field [0001] The present invention relates to an analysis tester, in particular to a medical analysis tester with controllable test temperature, which is used to test blood parameters, including cholesterol, triglyceride, blood sugar, glycosylated hemoglobin, lactic acid, uric acid, blood pH, blood oxygen , blood ion potassium, sodium, calcium, magnesium, HCO 3 - , PO 4 3- , partial pressure of oxygen, CO 2 The utility model relates to a medical analysis tester for indicators such as partial pressure, which belongs to the technical field of medical biosensors. Background technique [0002] The biochip / test strip that has been commonly used now is put into a detection device (such as a test strip jack) to test biological indicators (such as blood sugar components in blood), and optical or electrochemical detection techniques have been used. Its error can reach +-20%, but it has also been accepted by countries all over the world. Usually some errors will be gr...
