Liquid path system and hematology analyzer thereof

Abstract

The invention provides a liquid path system which comprises a liquid path of a pretreatment module, a liquid path of a reagent 1 input module, a liquid path of a reagent 2 input module, a liquid pathof a reagent 3 input module and a liquid path of a detection device cleaning module, wherein pipelines for detecting and analyzing lymphocytes, mononuclear cells, neutrophils, eosinophils and basophils are the same pipeline, the liquid path system is simplified, later installation and maintenance are facilitated, a solvent preheating device is added into the liquid path system, the reaction between reagents and samples can be accelerated, meanwhile, the invention also provides a hematology analyzer comprising the liquid path system, and the hematology analyzer is small in size.

Description

technical field [0001] The invention relates to a blood cell analyzer, in particular to a liquid path system of the blood cell analyzer. Background technique [0002] The blood cell analyzer is used to analyze the components in the blood. The five-differentiation blood cell analyzer analyzes and detects the white blood cells in the blood. The white blood cells in the blood are divided into the following five categories: lymphocytes, monocytes, and neutrophils. , basophils and eosinophils. The properties of basophils and the other four types of cells are quite different. It is difficult to separate the two types with the same reagents and optical detection, so it is necessary to add corresponding reagents to Basophils are tested separately, which means that these 5 types of cells in white blood cells need to be tested twice independently. The liquid path system includes modules such as liquid delivery, liquid detection, and liquid path cleaning. Now it needs The detection of...

[0002] The blood cell analyzer is used to analyze the components in the blood. The five-differentiation blood cell analyzer analyzes and detects the white blood cells in the blood. The white blood cells in the blood are divided into the following five categories: lymphocytes, monocytes, and neutrophils. , basophils and eosinophils. The properties of basophils and the other four types of cells are quite different. It is difficult to separate the two types with the same reagents and optical detection, so it is necessary to add corresponding reagents to Basophils are tested separately, which means that these 5 types of cells in white blood cells need to be tested twice independently. The liquid path system includes modules such as liquid delivery, liquid detection, and liquid path cleaning. Now it needs The detection of the two modules is carried out in a short period of time. At the same time, it is necessary to ensure that the liquid path is clean and will not contaminate each other. The overall design of the liquid path will be more complicated, which will increase the corresponding difficulty in the maintenance of the later instrument, and The manufacturing cost will also increase accordingly; in addition, when the corresponding detection reagents are added, these detection reagents will more or less cause losses to the leukocytes of the test object, so it is also necessary to add corresponding reagents to protect the leukocytes of the test object, which increases In the step of adding protective reagents, the liquid path in the instrument also needs to increase the corresponding liquid flow path. In this way, the liquid path system of the entire instrument is more complicated and the cost will be better. Therefore, it is necessary to propose a liquid path system with simple structure and easy installation. And a blood cell analyzer with easy maintenance, low cost, fast response time and accurate detection
