Description

technical field [0001] The invention relates to a simple self-destruction syringe, which belongs to medical syringes. Background technique [0002] At present, domestic and foreign production enterprises, medical institutions or individuals want to eliminate the reuse of syringes and meet the requirements of safe injections. At the same time, the World Health Organization, the World Children's Fund and the World Population Organization Foundation jointly stated that they are required to use self-destructing syringes as soon as possible. Syringes, many companies or individuals have designed various types of self-destructing syringes, including lock type, spring leaf type, and puncture type. Mass production, simple process and high production efficiency self-destruct syringes need to be improved. The patent No. ZL200520011459.8 designed by my country's Wuxi Yushou Medical Devices Co., Ltd. has been used in many provinces and cities in my country, as well as in many countries ...

AI Technical Summary

Problems solved by technology

However, due to the installation of stainless steel spring check parts on the push rod, it requires a lot of labor, and it is very difficult to reach 500 million, 1 billion or more. It is necessary to solve the problem of less labor, low cost, large output, and the use of medical staff. Handy self-destructing syringe, fully assembled with automatic equipment, could be improved
