Abstract

The present invention relates to a kind of anti-needle puncture syringe that can be prefilled with medicine, which comprises a needle barrel, a needle and a plunger, and also includes a needle cap; , there is a sealing film in the outlet of the syringe; the front end of the syringe is provided with a ring-wall structure matching part, and the matching part is provided with an external thread; the inner wall of the needle cap is provided with an internal thread matching the external thread and can be screwed to cover the outside of the matching part , the interior of the needle cap is provided with a raised structure along the central axis. The anti-needlestick syringe which can be preloaded with medicines of the present invention can be used for rapid and quantitatively accurate drug administration, and has the safety protection function of preventing needlestick injuries, and is suitable for self-rescue and mutual rescue analgesia for the wounded in emergency situations or rapid analgesia for rescuers. Pain administration is also suitable for pre-filled vaccines for the injection of vaccines against infectious diseases such as new coronary pneumonia.

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...
