Abstract

The invention relates to an injector capable of pre-loading medicines and preventing pricking wound. The injector capable of pre-loading medicines and preventing pricking wound comprises a syringe, asyringe needle and a plunger, and further comprises a syringe needle cap, wherein the syringe needle comprises a double-ended needle and a tail sleeve, the tail sleeve is embedded at an outlet of thesyringe, and a closing membrane is arranged in the outlet of the syringe; a cooperation part having a ringwall structure is arranged at the front end of the syringe, and is provided with an external thread; and an internal thread cooperating with the external thread is arranged on the inner wall of the syringe needle cap, the internal thread can cover the outer surface of the cooperation part in ascrewed connection manner, and a protrusion structure is arranged in the syringe needle cap along an axle wire. The injector capable of pre-loading medicines and resisting pricking wound disclosed bythe invention can be used for quick, quantitative and precise medicine application, has a safe protection function of resisting the pricking wound, is suitable for wounded people to perform self-rescue or mutual-rescue pain-alleviating medicine application or rescue staff to perform quick pain-alleviating medicine application in emergency circumstances, and is also suitable for pre-loading vaccines for injection of vaccines for infectious diseases including Corona Virus Disease 2019 and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a needle-stick injury-proof syringe which can be preloaded with medicine. Background technique [0002] Severe pain is one of the most common symptoms of war wounded. A large number of studies have shown that pain in the early stage of war trauma has a huge impact on the body's physiology, psychology, and rehabilitation. It is necessary to realize self-rescue, mutual rescue, analgesic administration or rescue of personnel in the early stage Rapid analgesic administration. At present, conventional injectable analgesic drugs are difficult to complete in the first-line treatment of the wounded. It is necessary to extract the drug from the ampoule bottle into the syringe on the battlefield and then inject it intramuscularly. The operation steps are complicated and time-consuming. And other environmental requirements are high, and rigid needles are used in emergen...
