A conventional whole blood transaminase testing instrument

Abstract

The invention discloses a conventional whole blood transaminase testing instrument. The invention comprises a casing, a temperature control incubator, a cuvette, a test strip bayonet, a light source, a transmitted light photoelectric connector and a reflected light photoelectric receiver arranged in the casing. The cuvette, cuvette and test strip bayonet are set in the shell of the temperature-controlled incubator, the cuvette is connected to the liquid delivery system to be tested and the waste liquid discharge system, and the transmitted light photoelectric connector is used to receive the light from the light source and pass through the cuvette After the transmitted light, the reflected light photoelectric receiver is used to receive the reflected light after the light from the light source is transmitted through the cuvette and then reflected by the test strip in the test strip bayonet. The invention not only has the advantages of high precision of dry chemical detection, fast test speed, less sample volume, saving reagents, and long storage time of reagents, but also has the advantages of low cost of wet chemical detection and low test interference. At present, the defects in the dry and wet biochemistry of the biochemical instrument are complemented.

Description

Technical field [0001] The invention relates to a medical transaminase testing instrument, in particular to a conventional whole blood transaminase testing instrument. Background technique [0002] Transaminase is the main item for clinical diagnosis of liver cell damage, and its level is often parallel to the severity of the disease. In various liver diseases such as acute hepatitis, chronic hepatitis and liver cirrhosis, the results of transaminase test are high. Therefore, the level of transaminase activity is an important indicator for detecting whether the liver system is normal. At present, the main method to detect transaminase is to do biochemical project testing in the laboratory of the hospital. Routine whole blood transaminase can be tested for wet chemistry and dry chemistry. [0003] The characteristics of wet chemical detection: accurate results, simple test method, but longer test time, larger reagent volume, shorter reagent shelf life, larger sample volume, lower ...

AI Technical Summary

Problems solved by technology

[0003] The characteristics of wet chemical detection: accurate results, simple test method, but longer test time, relatively large reagent volume, short shelf life of reagents, large sample volume, low cost, low interference, and fewer reagent test types

[0004] And dry chemical detection: the manufacturing precision of the instrument is high, the test speed is fast, ultra-trace analysis and detection, the test strips are stored for a long time, the cost is high, and the degree of interference is high, but there are few projects to be carried out, and the test strips require high precision.
