Quasi-automatic in-vitro detection device and method for measuring HCY (homocysteine) by colorimetric method

Abstract

The invention discloses a quasi-automatic in-vitro detection device and method for measuring HCY (homocysteine) by a colorimetric method. The quasi-automatic in-vitro detection device comprises a detection platform, wherein a photoelectric detection module with temperature control and stirring functions, a mechanical arm, a first loading pump, a second loading pump, a first container for containing a first detection reagent and a second container for containing a second detection reagent are arranged on the detection platform; a cuvette preloaded with the first detection reagent is placed on the photoelectric detection module, and a first sample loading needle for loading the first detection reagent and a second sample loading needle for loading the second detection reagent are respectively arranged on the mechanical arm. According to the quasi-automatic in-vitro detection device, automatic loading of the first detection reagent and the second detection reagent is realized, the problem that a detection result is influenced due to reagent content change caused by volatilization of the first detection reagent is avoided, the labor cost of HCY detection is saved, the manual monitoring link is omitted, and the influence of misoperation in the process of manually dropping the detection reagents on the detection result can be prevented as far as possible.

Description

technical field

[0001] The invention relates to in vitro diagnostic equipment, in particular to a quasi-automatic in vitro detection equipment and method for measuring HCY using a colorimetric method. Background technique

[0002] Homocysteine ​​(HCY) is a sulfur-containing amino acid produced by the metabolism of methionine. 80% of HCY is bound to protein through disulfide bonds in the blood, and only a small part of free homocysteine ​​participates in the circulation. The level of HCY is closely related to cardiovascular diseases and is an important risk factor for the onset of cardiovascular diseases. The increased Hcy in the blood stimulates the blood vessel wall to cause damage to the arterial vessels, leading to inflammation and plaque formation on the vessel wall, and finally causes cardiac blood flow. stymied. Vitamin B nutritional deficiencies will be accompanied by moderate or mild HCY elevation, which will also increase the risk of heart disease. In recent years...
