Abstract

The invention discloses a particle analyzer as well as a liquid path system and a waste liquid discharging method thereof. The liquid path system of the particle analyzer comprises a sheath liquid supply module used for supplying sheath liquid, a waste liquid receiving module used for receiving waste liquid, a sample supply module provided with a sampling needle and used for collecting and supplying samples, a flowing chamber used for flowing of the sheath liquid carrying samples, and a washing module, wherein the flowing chamber is provided with a sample inlet, a sheath liquid inlet and a waste liquid outlet; the sample inlet is communicated with the sampling needle; the sheath liquid inlet is communicated with the sheath liquid supply module; the waste liquid outlet is communicated withthe waste liquid receiving module through a first waste liquid pipe; the washing module is communicated with the sheath liquid feeding module through a first washing pipe so as to wash the outer wallof the sampling needle; the washing module is communicated with the waste liquid receiving module through a second waste liquid pipe so as to discharge the waste liquid of the washing module out of the waste liquid receiving module. The particle analyzer using the liquid path system is high in signal detection stability.

Description

technical field [0001] The present invention relates to the technical field of cell analysis and detection equipment, in particular to a particle analyzer, its liquid path system, and a waste liquid discharge method, and the particle analyzer is especially a cell analyzer. Background technique [0002] Flow cytometer is a device for automatic analysis and sorting of cells or biological particles, which can quickly detect, store, and display a series of important biophysical and biochemical characteristic parameters of dispersed cells suspended in liquid, and Specified cell subgroups can be sorted out according to the pre-selected parameter range, which has been widely used in basic researches such as cell biology, immunology, physiology, molecular biology, etc., and also used in medical clinical diagnosis, environmental detection, etc. . Among them, the fluid path system is one of the core systems of the flow cytometer. Through the fluid path system, the sheath fluid is wra...
