[0002] At present, the method of filtering white blood cells using a blood filtration device is to hang a whole blood bag on a hook plate, and then use gravity to make the whole blood in the whole blood bag flow downward and pass through the filter, thereby filtering the white blood cells in the whole blood in the bag, and then collecting the leukocyte-reduced whole blood into the leukocyte-reduced blood bag. However, there is a plug rod for sealing at the top entrance of each whole blood bag to ensure the vacuum sealing effect of the blood bag. Before hanging the whole blood bag on the hook plate, medical staff need to manually break the plug rod to connect the whole blood bag with the catheter. Manually breaking the plug rod is not only time-consuming, labor-intensive, and inefficient, but medical staff can easily suffer from occupational diseases such as thumb tenosynovitis if they manually break the plug rod for a long time.
