Description

Safety syringe

Technical Field

The utility model relates to the technical field of medical supplies, concretely relates to safe type syringe.

Background

The structure of a medical injector mostly comprises a needle cap, a needle head, a latex head, a needle cylinder, a piston and the like, wherein the needle cap is sleeved outside the needle head to play a role in protection. The connection of current needle cap and syringe needle and the connection of syringe needle and cylinder all realize through the plug form, and the needle cap is connected comparatively closely with the syringe needle, and medical personnel can be often too tight and power is excessive when pulling out the needle cap because of the needle cap, because inertial action kick-backs and is stabbed by the syringe needle, leads to the sharp ware to hinder frequent emergence, seriously influences medical personnel's physical and mental health.

Chinese utility model patent CN203677663U discloses an anti-stab syringe, comprising a syringe, a needle and a needle cap, wherein the needle is divided into a pintle, a needle stem and a needle point, one end of the pintle is connected with the nipple, one end of the needle stem is mounted at the other end of the pintle, and the needle cap is mounted on the pintle after being sleeved on the needle; the needle cap is connected with the pintle through threads. The hard connection between the needle cap and the needle plug is changed into the spiral connection, so that the incidence rate of needle stick injuries caused by poor strength control when medical staff pull out the needle is reduced. The above-mentioned patent has surely improved the safety in utilization, but spiral connection is no matter when taking or when the injection after with the needle cap cover back all can influence operating efficiency.
