Micro-fluidic chip, hemocyte analysis system and hemocyte analysis method

Abstract

The invention relates to a micro-fluidic chip, a hemocyte analysis system and a hemocyte analysis method. The micro-fluidic chip comprises at least one detection flow channel, wherein each detection flow channel comprises a first sample inlet, a second sample inlet, a sample micro flow channel, an auxiliary solution micro flow channel and a convergence micro flow channel, wherein the sample micro flow channel is connected with the first sample inlet; the auxiliary solution micro flow channel is connected with the second sample inlet; the convergence micro flow channel is connected with the sample micro flow channel and the auxiliary solution micro flow channel; a small hole is formed in the convergence micro flow channel; and a first electrode and a second electrode are respectively arranged on two sides of the small hole. Hemocytes can be accurately counted by measuring sizes of hemocytes of a sample to be detected by detecting voltage change between the first electrode and the second electrode of the micro-fluidic chip, so that the measuring cost is greatly reduced, and the measuring efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of blood cell analysis, in particular to a microfluidic chip, a blood cell analysis system and a blood cell analysis method. Background technique [0002] At present, the determination of blood cell typing and blood routine is generally carried out in specific laboratories through blood cell analyzers. Hematology analyzers are bulky and expensive, requiring special personnel to use and regular maintenance. The matching measurement reagents are also expensive and costly. They are generally suitable for inspection departments in hospitals with more test samples and more concentrated. Primary-level medical units such as community workstations, village clinics, and private clinics often have small sample sizes and very scattered samples in the time dimension. When using existing blood cell analyzers, high maintenance costs and high requirements for operators will occur. , No portability and other issues. Summary of...

AI Technical Summary

Problems solved by technology

Hematology analyzers are bulky and expensive, and require special personnel to use and perform regular maintenance. The matching reagents are also more expensive, and the cost pressure is high. It is generally suitable for hospital inspection departments with a large number of test samples and relatively concentrated

Grass-roots medical units such as community workstations, village clinics, private clinics, etc., often have small sample sizes, and the samples are very scattered in the time dimension. When using existing blood cell analyzers, there will be high maintenance costs and high requirements for operators. , lack of portability and other issues
