Background

At present, the disposable sterile syringe for human body injection in China is widely used due to the advantages of reliable sterilization and convenient taking. Still has certain defects, and the disposable sterile syringe is easy to cause needle stick injury in the using process. Needle stick injuries are a common occupational exposure for healthcare workers and many diseases are transmitted through this process, with over a million healthcare workers being pricked with a disposable sterile syringe needle each year, and some people are therefore infected with blood-borne diseases. The needle stick injury occurs in the following steps: 1. when medicine is pumped and liquid is prepared; 2. when used syringes or infusion needles are disposed of; 3. when the needle cap is sleeved back; 4. when puncturing; 5. when the needle is pulled out. The syringe is treated, and the phenomenon that the needle cap is directly sleeved back by hands after injection is recognized as the high-position behavior of the needle stick injury. Although it is clinically prescribed that the double-handed back cap is prohibited, this situation sometimes occurs. According to the research, the following results are shown: the incidence of needle stick injuries by nurses was 77.9%. The proportion of needle stick injuries caused by back sleeving of the needle cap is the largest.

The existing novel injector is expensive in manufacturing cost and complex in use, so that the injector is not popularized in a large range. In clinical care work, a syringe which sucks liquid medicine is often placed in a treatment disc, and the injection is carried out after a patient is assisted to be disinfected, and during the period, if a needle cap is not sleeved back, the pollution is caused, but the danger of puncture is increased due to the sleeved back.
