Injection needle is one of the largest selling medical devices in the world. However, it is worth paying attention to the fact that millions of people are injured every year in hospitals around the world due to needle breakage or improper operation of medical staff. Statistics released by the American Medical Association show that about 1 million health care workers are accidentally pricking themselves with needles each year in the United States alone, and at least 1,000 of them are infected with hepatitis B, hepatitis C and HIV. The cost of emergency treatment for medical staff and patients injured by a broken blood needle is 3,000 dollars per person. 
[0003 The medical risks associated with ordinary needles are no less than those associated with syringes. Companies at home and abroad have been vigorously into safe injection in medical equipment research and development, but there are a lot of the safe injection equipment exist on the market: one is the high cost of production, the other is a complex production process; the third is the production quality is difficult to guarantee; fourth, medical personnel of tedious; five is hard to ensure safe function. In addition, the injection needle is too tight due to material reasons in the process of retraction. [0004] Therefore, the development of a disposable retraction safety injection needle has great and long-term significance to develop a disposable retractable safety injection needle. Therefore, a safe syringe is very important. We can provide you with high-quality services and high-quality safe syringes safety needle syringe Retractalbe syringe Auto-disable syringe.
Thus, by connecting the vertebrae 14, the injection needle can be easily connected externally to other parts, thus widening the use range of the injection needle. [0031] Further, in the card slot with the top of the 12 department is equipped with a core rod for 121, 2 inside the upper part of the coat has a coat for the 21st, when the core rod 1 is pulling up to the top of the coat 2, mandrel for 121 and coat for 21 contact, core bar for 121 and coat for 21 each card buckle, core rod 1 can no longer be upward lift, can effectively prevent the pull [0032] In addition, in order to facilitate production, core rod 1 can be connected by two rods in the middle position, between the rod through a head interference fit and glue bonding, so as to further ensure the firmness of the connection between the two. [0033 according to the above structure, the specific use of the present invention is as follows: described with infusion products safe injection needle. When the infusion is finished, the coat 2 push forward, piston 5 relative coat 2 produce relative displacement, which drives the mandrel coat 1 and 2 relative movement occurred until the core rod for 121 to 21 screens to coat. At this point, the needle 3 is hidden inside the jacket 2, so that the needle 3 will not be exposed and accidentally stabbed. The safety injection needle described in the invention has simple structure and convenient use, which can effectively prevent the injection needle injury accident and greatly reduce the medical risk of the injection needle.
