Abstract

PURPOSE:To prevent the occurrence of an stitching accident due to the exposure of the needle tip of an injector, and increase safety by forming a safety cover of an elastic member along the needle of the injector. CONSTITUTION:A safety cover composed of an elastic member having a guide rod 3 at the forward end via a bellows section is coupled to the needle section 5 of an injector 7, and the mounting opening of the cover at the base end is coupled to the injection outlet of the injector 7, thereby fastening the safety cover. According to this construction, the needle section 5 is not exposed, and the rod 3 is made to retreat against elasticity only at the time of giving an injection, thereby exposing a needle tip from the safety cover. When a needle is pulled out from a body after giving an injection, the rod 3 again elongates, thereby recovering the needle tip.

全に、元の様に注射針先案内部３の中に収納される。Operation When the injection needle is pierced into the skin, the injection needle tip guide portion 3 is strongly brought into contact with the skin. Therefore, the elastic member 1 of the present invention is pressed when the operation is stopped and further pushed by a braking action due to a kind of friction. Shrinking needle tip pierces the skin. When pulling out the injection needle from the inside of the skin, at the same time as pulling out the injection needle by pressing the injection port on the skin with absorbent cotton, the elastic member of the present invention stretches itself and the needle tip is completely guided like the original. It is stored in the part 3.

る。The needle tip of the injection needle is exposed from the safety cover of the present invention only when the injection needle is injected, and is completely housed in the safety cover when the injection needle is removed from the body. Until now, doctors and nurses working at medical institutions accidentally pierced their fingers with the injection needles used for patients, and there were many tragic accidents caused by hepatitis and AIDS. There is a risk of These accidents are horrifying accidents that make people working to save patients a little careless and fatal. Therefore, by using the syringe with the present invention, these tragic accidents can be prevented and medical personnel can be provided with safe treatment.
