New description: [New technical field] This creation is a kind of syringe, especially a recyclable full syringe, which is simple in structure and convenient in combination. The daughter of the ten members [prior technology] In the course of diagnosis and treatment, medical staff often use injection drugs or blood. However, after the traditional syringe is used, the chance of the needle being stabbed by the medical staff is greatly increased. Some blood-borne diseases are now susceptible to infections such as hepatitis or AIDS. The life safety of the people is a major cause of birth, and the West 4 people have become a major hazard. ^ Can also be collected. Bell's full syringe has the shape of a safety syringe that is more complicated and more flexible.
