Multichannel trace quantification system of hematology analyzer

Abstract

The invention discloses a multichannel trace quantification system of a hematology analyzer, which comprises a ceramic blood dividing valve front cover, a ceramic flow dividing sheet, a ceramic blooddividing valve rear cover, a rotary valve sheet mechanism and a five-channel trace quantitative blood dividing valve, the ceramic blood dividing valve front cover is rotationally connected with the ceramic flow dividing sheet; the ceramic blood dividing valve rear cover is rotationally connected with the ceramic flow dividing sheet; the valve core is positioned on one side far away from the ceramic blood distribution valve front cover; the rotary valve plate mechanism is fixedly connected with the ceramic blood distribution valve front cover; the five-channel trace quantitative blood distribution valve is fixedly connected with the ceramic blood distribution valve front cover, the ceramic flow distribution sheet and the ceramic blood distribution valve rear cover; the five-channel micro quantitative blood distribution valve comprises a ceramic blood distribution valve front cover, a ceramic flow distribution part and a ceramic blood distribution valve rear cover, the five-channel microquantitative blood distribution valve comprises five different channels which are arranged in a circular array mode, the number of detection types is increased, and the detection time is shortened.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-channel microquantification system of a blood cell analyzer. Background technique [0002] The main components of human blood are white blood cells, red blood cells, platelets and other components, among which white blood cells are divided into five types of white blood cells: lymphocytes, monocytes, basophils, neutrophils, and eosinophils. The counting of cells in the blood is performed to provide information support for the next step of medical treatment. This is the routine and the most common five classifications. Therefore, medical units have more and more urgent needs for blood testing equipment automation, speed and testing items. To complete the detection results in a short time, it is necessary to complete the detection in several detection channels at the same time. Therefore, it is necessary to draw multiple sections of blood and distribute them to diff...

[0002] The main components of human blood are white blood cells, red blood cells, platelets and other components, among which white blood cells are divided into five types of white blood cells: lymphocytes, monocytes, basophils, neutrophils, and eosinophils. The counting of cells in the blood is performed to provide information support for the next step of medical treatment. This is the routine and the most common five classifications. Therefore, medical units have more and more urgent needs for blood testing equipment automation, speed and testing items. To complete the detection results in a short time, it is necessary to complete the detection in several detection channels at the same time. Therefore, it is necessary to draw multiple sections of blood and distribute them to different channels according to different volumes for detection. Most of the existing five-classification instruments are based on WBC , RBC, WOC channels are used to suck samples, and then distribute them to the corresponding channels. The types are relatively small and single, and the corresponding detection time is also increased.
