[0028] Example 2

[0029] The difference between this embodiment and embodiment 1 is that the heat dissipation assembly 2 includes an air inlet fan 21, an air inlet port 22, a heat dissipation fan 23 and a heat dissipation port 24, wherein the air inlet port 22 is provided at the upper end of one side of the shell 1, the air inlet fan 21 is provided on the side of the air inlet port 22, and the heat dissipation port 24 is provided at the lower end of the other side of the shell 1, and the heat dissipation fan 23 is provided on the side of the heat dissipation port 24.

By allowing the gas in the shell 1 to circulate, heat dissipation is achieved, avoiding excessive temperature in the shell 1, and facilitating long-term use.

[0034] The working principle and use process of the utility model are as follows: after the preparations for blood donation are completed, the blood donor is punctured, at which time the induction switch 1 6 is turned on, and the other induction switches 2 7 and 3 8 are turned off, blood collection begins, and the blood flows to the whole blood bag 9. The anticoagulant peristaltic pump 18 draws the solvent in the anticoagulant 5 and enters the whole blood bag 9 together with the blood. When the weight set by the weighing oscillator is reached, the induction switch 1 6 is turned off, the blood donor completes the blood donation, and the blood collection needle 4 is pulled out to treat the puncture wound. At the same time, the centrifuge 12 starts to rotate. When the speed reaches the speed, the induction switch 2 7 is turned on, and the whole blood peristaltic pump 10 starts to work and transports the whole blood to the blood separation cup 11. Due to the different specific gravity of red blood cells and plasma, the blood separation cup 11 separates the whole blood under high-speed rotation. The plasma flows into the plasma bag 13. When the color sensor 14 detects that red blood cells pass through, the centrifuge 12 stops rotating, the whole blood peristaltic pump 10 stops working, and the induction switch 2 7 is closed. After the centrifuge 12 stops completely, the induction switch 3 8 is opened, and the red blood cell peristaltic pump 15 starts working. At this time, the red blood cells enter the red blood cell bag 16. If the separation of whole blood is not completed in one cycle, the air sensor 17 detects air, the equipment stops, and the separation work is repeated by pressing the start button again through naked eye observation; the air intake fan 21 sucks the air outside the shell 1 into the shell 1 from the air inlet 22, and the heat dissipation fan 23 discharges the gas in the shell 1. By circulating the gas in the shell 1, heat dissipation is achieved to avoid excessive temperature in the shell 1, which is convenient for long-term use.
