Backwashing flow path system of glycated hemoglobin analyzer

Abstract

The invention belongs to medical equipment, relates to a flow path structure of a glycated hemoglobin analyzer, in particular to a backwashing flow path structure of a glycated hemoglobin analyzer. The backwashing flow path system of the glycated hemoglobin analyzer comprises a peristaltic pump positioned on a liquid feeding pipeline, wherein a liquid discharging hole of the peristaltic pump is introduced into a waste liquid bottle through a liquid discharging pipe after sequentially passing through a first electromagnetic valve, a cation exchange resin chromatographic column, a cuvette cell and a second electromagnetic valve; and a third electromagnetic valve is connected between the liquid discharging hole of the peristaltic pump and an outlet of the cuvette cell, and a branching pipeline is arranged in front of the inlet end of the cation exchange resin chromatographic column and is connected with the liquid discharging pipeline through a fourth electromagnetic pipeline. The invention has the advantages of being capable of avoiding aggregation and blockage of floccules in a detected sample at the chromatographic column and a filter screen of the glycated hemoglobin analyzer, prolonging the service life of the chromatographic column, improving reliability of a detection process, and being convenient for operation and maintenance and low in cost.

AI Technical Summary

Benefits of technology

This technology allows for better control over blood glucose levels during medical tests without blocking or interfering with other components such as certain proteins found inside red cells (hemoglobles). By combining these two channels together, this technology improves accuracy while reducing costs compared to existing methods like enzyme-linked immunosorbents assays.

Problems solved by technology

The technical problem addressed during research into an improved way for separating glycohemagglutins (GH) based upon their ability to bind specifically to other molecules like sugars has been identified. This could lead to reduced accuracy when analyzing large amounts of biological material due to contamination caused by residual cells that may stick tightly together. Additionally, there have been attempts to improve the separation efficiency without increasing complexity or cost-effectiveness while ensuring reliable results.
