[0072] When the second two-way valve 302 is in the middle position, Fig.12 As shown, the second valve stem 30201 of the second two-way valve 302 disconnects the left connecting hole 30110, the middle connecting hole 30111, the right connecting hole 30112 and the water inlet hole 30106. At this time, the first through hole 30101, the middle through hole 30102 and the second through hole 30103 work separately.

[0073] When the second two-way valve 302 moves to the left, the three-way hole 30203 on the second valve stem 30201 is connected with the left connecting hole 30110, the middle connecting hole 30111 and the right connecting hole 30112, thereby connecting the left connecting hole 30110, the middle connecting hole 30111 and the right connecting hole 30112. At this time, the first connecting hole 30101, the middle connecting hole 30102 and the second connecting hole 30103 work simultaneously.

[0074] When the second two-way valve 302 moves to the right, the left connecting hole 30110, the middle connecting hole 30111, the right connecting hole 30112 and the water inlet hole 30106 of the four-way hole 30202 on the second valve stem 30201 are connected, and the second valve stem 30201 presses the first telescopic pin 303 downward while moving to the right, and the first telescopic pin 303 moves downward. Because the first telescopic pin 303 is provided with a first conical head 30302 and the second telescopic pin 304 is provided with a second conical head, the first conical head 30302 of the first telescopic pin 303 and the second conical head 30402 of the second telescopic pin 304 are slidably connected while the first telescopic pin 303 moves downward, as shown in FIG. Fig.13 As shown, under the pressure of the first telescopic pin 303, the second telescopic pins 304 on both sides move in opposite directions. At this time, the first telescopic pin 303 blocks the middle through hole 30102, and the second telescopic pins 304 on both sides respectively block the first through hole 30101 and the second through hole 30103. At this time, there is no blood circulation in the first through hole 30101, the middle through hole 30102 and the second through hole 30103, and the blood separator stops working. After the blood separator stops working, the water inlet hole 30106 is connected to the cleaning device to clean and disinfect the blood circulation path of the entire blood separator to keep the passage clean and avoid cross-infection of blood.

[0075] The installation cabinet 2 also includes a control unit, which is provided with a start-stop switch 4, an emergency stop switch 5 and an alarm 6. The start-stop switch 4 is used to control the start and stop of the blood separator, the emergency stop switch 5 is used to temporarily stop the machine in an emergency, and the alarm 6 is used to alarm when the equipment fails. The pressure sensor 10302, the monitoring box positioning valve 104, the first two-way valve 1030102 and the second two-way valve 302 are all electrically connected to the control unit.

[0076] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
