Description
Translated fromChinese技术领域technical field
本发明涉及注射输液领域，具体的是一种降低职业暴露风险的注射输液针头。The invention relates to the field of injection and infusion, in particular to an injection and infusion needle for reducing occupational exposure risk.
背景技术Background technique
静脉输液是利用大气压和液体静压原理将大量无菌液体、电解质、药物由静脉输入体内的方法。静脉输液针用于连接注射器，输液器，输血器进行静脉输注药液和输血。Intravenous infusion is a method of infusing a large amount of sterile liquid, electrolytes, and drugs into the body through the vein by using the principles of atmospheric pressure and hydrostatic pressure. Intravenous infusion needles are used to connect syringes, infusion sets, and blood transfusion sets for intravenous infusion of medicines and blood.
当前护士的职业暴露是一个严肃的话题，尤其是在给病人输液或注射结束之后拔出针头并插入针头套的时候，护士们动作娴熟，速度较快，非常容易误伤自己的手指造成职业暴露，容易划伤自身或病人，若病人带有体液传播的病毒那就更加危险。At present, the occupational exposure of nurses is a serious topic, especially when the needle is pulled out and the needle cover is inserted after the infusion or injection is completed. Nurses are skilled and fast, and it is very easy to accidentally injure their fingers and cause occupational exposure. It is easy to scratch itself or the patient, and it is even more dangerous if the patient has a virus transmitted by bodily fluids.
发明内容SUMMARY OF THE INVENTION
为解决上述背景技术中提到的不足，本发明的目的在于提供一种降低职业暴露风险的注射输液针头，本发明将输液针头分为针管和针头两部分，采用卡扣或者螺纹的方式将二者连接，安装牢固且安装方便，便于针头进入人体内。In order to solve the deficiencies mentioned in the above background technology, the purpose of the present invention is to provide a needle for injection and infusion that reduces the risk of occupational exposure. It is connected by the user, the installation is firm and convenient, and it is convenient for the needle to enter the human body.
同时，针头的材质为可迅速溶解于水、血液、组织液的材料或者遇水变软、烘干变硬的材料，可迅速溶解于水、血液、组织液的材料为氯化钠晶体或者葡萄糖晶体，遇水变软、烘干变硬的材料为新型塑料或新型纳米材料。氯化钠晶体、葡萄糖晶体遇水会逐渐溶解，新型塑料或新型纳米材料在针头拔出时呈软化状态，护士在拔针时溶解或者软化的针头不会划伤自身或病人，降低了危险性，也降低了血液传播的可能性。At the same time, the material of the needle is a material that can be quickly dissolved in water, blood, and tissue fluid, or a material that becomes soft and hard when exposed to water. The material that can quickly dissolve in water, blood, and tissue fluid is sodium chloride crystals or glucose crystals.
