Problems solved by technology

In foreign countries, many scholars have studied the safety device of injection needles. The most successful inventor is Hollister, William H. His "Safety Needle Container", US Patent No. 4,982,842, mainly solves the problem of one-handed operation and one-time locking. Rear needle body, and reducing the dead space of the liquid medicine, etc., but it is only a safety accessory assembled on the needle seat of the injection needle. Its locking of the needle body after use does not mean destruction. Opening its locking device maliciously, The injection needle can still be used again, and it does not have a positioning function for the rotation of the needle sheath, and cannot be applied to the current requirements for the sheath positioning of various advanced medical needles during operation, so it needs to be improved

A safety protector for ensuring that the medical injector can be used only once is composed of a needle holder and a fastening cover. After its needle holder and fastening cover are closed, a sharp object in the push handle can prick the needle holder and injector to destroy it.

Description

Technical field: [0001] The invention relates to medical needles with needle holders in medical devices, such as injection needles, infusion needles, blood-drawing needles, venous indwelling needles, puncture needles, etc., especially safety protection devices for single-use medical needles with needle holders . Background technique: [0002] With the gradual understanding of infectious pathogens, the majority of medical workers have realized the necessity of using medical needles with safety protection devices to avoid accidental stab wounds during treatment and lead to blood-borne pathogen infection, and only once The importance of sexual use devices in preventing cross-sexual infection. In the past two years, many syringes, infusions or blood drawers with self-destructive use devices or safety protection devices with different designs have been born in the domestic and foreign markets. Because these design devices focus on the safety effect of the overall self-destruct ...
