Connected to the cable 21 in a predetermined manner (see Fig. 1). Place the protector 16 at an appropriate location on the tube 12 or temporarily fix it.
- the operator such as a medical worker punctures the blood vessel 14 through the blood of the donor (donor) while holding the hub 22, and performs a predetermined medical treatment such as blood collection. Do. At this time, the blood into which the blood collection needle 14 force has been introduced passes through the tube 12 and is stored in the storage space 21c of the bag 21.
- the blood collection needle 14 is dropped into the protector 16 and the tube 12 is lowered. Pull from.
