Embodiment Construction
[0026] like Figure 4As shown, the flow cytometric detection system provided in this embodiment includes a waste liquid pool 1, a flow chamber 2, a sample syringe 3, a reaction pool 4, a sheath fluid pool 5, a negative pressure device 6, a driving device 7, and related valves and pipelines . The flow chamber 2 is the key component for detection and has at least three ports, which are the sample injection needle 21 , the sheath fluid inlet 22 and the outlet 23 . The sample injection needle 21 is connected to the syringe main interface 31 through a pipeline. The sheath fluid inlet 22 is connected to the sheath fluid tank 5 or other pressure outlet storage tanks through a pipeline, and the opening and closing of this section of pipeline is controlled by the fourth valve 11 . In this embodiment, the driving of the sheath fluid is accomplished by the positive pressure of the sheath fluid pool 5 , and the flow velocity of the sheath fluid can be adjusted by adjusting the pressure ...
