Abstract

The invention discloses a safety syringe. The safety syringe consists of a jacket, a core rod, a rubber plug, a connecting piece, a seal ring and a needle seat, and is characterized in that the front part of the inner wall of the jacket is uniformly provided with jacket grooves; the outer surface of the needle seat is uniformly provided with needle seat bosses which are matched with the jacket grooves; a needle seat elastic claw which is matched with the core rod is machined on the inner side of a needle seat cone head; the outer surface of the connecting piece is provided with connecting piece bosses which are matched with the jacket grooves; the inner wall of the top of the connecting piece is provided with a connecting piece elastic claw which is matched with the core rod; and the top end of the core rod is provided with a front tower-shaped barb and a rear tower-shaped barb which are matched with the needle seat elastic claw and the connecting piece elastic claw respectively. After the product is used, the core rod is drawn back to drive an entire injection needle to contract into the syringe jacket and is clamped in the jacket, so as to prevent the injection needle from getting in and out from the two ends of the jacket, so that medical care personnel need not to pull out the injection needle, and stick injuries of the medical care personnel or other people are prevented and reduced.

Description

technical field [0001] The invention relates to a medical device for injection, in particular to a safety syringe. Background technique [0002] At present, the syringes commonly used in the medical field are basically composed of a jacket, a rubber stopper and a core rod. The rubber plug is sleeved on the head of the core rod to form a push rod, and the push rod is loaded into the inner cavity of the jacket. Before use, the medical staff should tighten the injection needle and the needle seat cone of the syringe. After suctioning and injecting the medicinal liquid, in order to prevent the medical supplies cleaning personnel from being stabbed by the needle, the medical staff should separate the injection needle from the syringe, deal with. However, during the separation process of medical staff, the exposed injection needles used by them are very easy to injure themselves or other personnel, resulting in infection. Contents of the invention [0003] The purpose of the ...
