Abstract

The invention discloses a fluid system of a flow cytometer and a flow cell detecting method. The fluid system of the flow cytometer comprises a sheath flow injector, a sample flow injector, a blood sampling injector, a hemolytic agent injector, a blood sampling needle, a reaction tank, a flowing chamber, a diluent barrel, a hemolytic agent bottle, a first motor, a second motor and a third motor, wherein the sheath flow injector is driven by the first motor; the hemolytic agent injector is driven by the third motor; and the sample flow injector and the blood sampling injector are driven by the second motor. The sample flow injector and the blood sampling injector share the second motor, and are arranged in a moment balancing manner; the second motor is arranged between the two injectors; the cost of the system is reduced; the whole rigidity and the inertia of the system are also improved; sample flow is pushed by the injector stably; and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of biomedical detection, in particular to a flow cytometer fluid system and a flow cytometry detection method. Background technique [0002] Flow cytometry is a blood analysis instrument that controls cells to pass through the detection area one by one through flow cytometry. Flow cytometry means that the cell flow (also called sample flow) is wrapped in the sheath fluid, and the cells line up through the flow chamber detection area. Advanced fluid control technology, which can avoid the problem of inaccurate detection caused by cells passing through the detection area according to irregular routes, and can greatly reduce the probability of missed detection caused by overlapping cells passing through the detection area. [0003] Existing flow cytometry is mainly divided into two categories. The first category is that both the sheath flow and the sample flow are pushed by a syringe. The second type is that the sample f...
