<P>PROBLEM TO BE SOLVED: To safely and surely cover an injecting needle by a simple procedure. <P>SOLUTION: This syringe is equipped with the injecting needle which has a locking chip on the rear end, an external cylinder which detachably supports the injecting needle through the locking chip, and a plunger. In this case, the plunger forms a filling space for a medicine in the external cylinder, and discharges the medicine from the distal end of the injecting needle by sliding. In such a syringe, on the injecting needle, a sliding cover which covers at least the needle tip by moving toward the distal end, and a stopper which comes into contact with the rear end of the cover when the sliding cover passes through, and stops the sliding cover from moving backward are arranged. <P>COPYRIGHT: (C)2003,JPO |
