Abstract

The invention discloses a flow cytometer fluid system and a flow cytometer detection method. The flow cytometer fluid system includes a sheath flow syringe, a sample flow syringe, a blood sampling syringe, a hemolyzing agent syringe, a blood sampling needle, a reaction pool, and a flow chamber. , diluent bucket, hemolytic agent bottle, first motor, second motor, third motor, the sheath flow injector is driven by the first motor, the hemolytic agent injector is driven by the third motor, the sample flow injector and blood collection The syringes are all driven by a second motor. In the present invention, the drive motors of the sample flow injector and the blood collection injector are combined into one, and the two injectors are arranged in a torque balance, and the motors are arranged between the two injectors, which not only reduces the cost of the system, but also increases the overall rigidity of the system And inertia, make the syringe push the sample flow more smoothly and improve the detection accuracy.

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...
