Similarly, the other surface abuts the base end of the needle base 21, respectively. When the syringe barrel 22 is further moved, the needle base 21
A force is applied to the needle base 21 to pull it toward the other short side wall 15, and this force causes the needle base 21 to come off the tube tip 24 (see Fig. 3c), and due to its own weight, the needle base 21 comes off the long hole 13.
It falls through the container 1 and is accommodated in the container 1. In this way, the injection needle 20 is removed from the injection barrel 22. When the container 1 is full of used injection needles 20, the container 1 is discarded. Then, the needle tube 25 of the injection needle 20
Blood and drugs attached to the liquid absorbing and holding material 6
