Specifically, the tension spring provides upward pulling force for the hanging piece 23, so as to tighten the suspended blood bag 11a and keep the suspended blood bag 11a stable.

[0050] It can be understood that the lifting driving unit 30 can be a cylinder, a hydraulic cylinder or any driving component that can drive the hanging rack 20 to slide.

[0051] In one embodiment, as shown in Figure 1 and 3 , the lifting driving unit 30 includes a motor 31 and a lead screw 32, the lead screw 32 is rotationally connected to the rack 10 and extends in the height direction of the rack 10, the motor 31 is fixed to the rack 10 and connected to the lead screw 32, for driving the lead screw 32 to rotate, and the hanging rack 20 is threadedly connected to the lead screw 32 through a lead screw nut.

Specifically, through the arrangement, the blood bag 11a can be prevented from shaking, and the stability of the blood bag 11a during hanging can be ensured.

[0056] In one of the embodiments, the blood bag hanging device further comprises an identification module (not shown in the figure), which is arranged on the rack 10 and is electrically connected with the lifting driving unit 30, and is used for identifying the height of the human body. Specifically, the identification unit identifies the height of the worker who hangs the blood bag 11a, so that the identification signal sent to the controller can control the lifting driving unit 30 to drive the hanging rack 20 to move to a suitable height, thereby facilitating the worker to hang, reducing the manpower required for hanging the blood bag 11a, and improving the hanging efficiency of the blood bag 11a.

[0057] As shown in Figure 3 The embodiment of the utility model further provides a white blood cell filtering system, and the white blood cell filtering system comprises the blood bag hanging device. Specifically, when the blood bag 11a is hung, the lifting driving unit 30 drives the hanging rack 20 to descend, so that the hanging rack 20 is at a height position suitable for the height of the human body, thereby facilitating the hanging of the blood bag 11a, reducing the manpower required for hanging the blood bag 11a, improving the hanging efficiency of the blood bag 11a, and after the blood bag 11a is hung, the lifting driving unit 30 drives the hanging rack to ascend, so that the position of the blood bag 11a is adjusted to be high, thereby accelerating the flow rate of the blood and improving the white blood cell filtering efficiency of the blood.

[0058] In the embodiment, the white blood cell filtering system further comprises a supporting unit 40 and a breaking unit 50. The supporting unit 40 is arranged at the bottom of the rack 10 and is used for supporting the collecting bag 14a. The breaking unit 50 is arranged on the blood bag hanging device and is used for breaking the air inlet valve 111a of the blood bag 11a.

[0059] The white blood filtering system of the embodiment can be installed on the blood bag device 10a by hanging the blood bag 11a filled with blood on the blood bag hanging device and connecting the air inlet valve 111a of the blood bag 11a to the breaking unit 50 when the white blood filtering work is performed. After the installation of the blood bag device 10a is completed, the air inlet valve 111a on the blood bag 11a is broken by the breaking unit 50, so that the gas enters the inside of the blood bag 11a, the blood in the blood bag 11a flows into the catheter 12a, then flows through the white blood filtering module 13a, and then flows into the collecting bag 14a after being filtered by the white blood filtering module 13a. The blood filtered by the collecting bag 14a is collected, so that the white blood filtering of the blood can be realized.
