Abstract

The invention belongs to the technical field of medical appliances, and relates to a structure of a medical syringe, which solves the technical problems that the existing medical syringes cannot project and cannot control the amount of injected medicine. The structure of the medical syringe includes a needle, a syringe with a cavity, and a piston slidingly arranged in the syringe. At the front end of the barrel, a disposable diaphragm is provided in the cavity of the barrel close to the front end of the barrel; two electrode contacts are set on the outer end surface of the front end of the barrel, and two electrode contacts are fixed on the outer peripheral surface of the needle to conduct two contacts. The metal sheet of the electrode contact; the piston rod is made of a magnet or a magnetic piece is fixed on the piston rod, a coil is provided on the outer sleeve of the syringe, and a battery is fixed on the syringe, and the battery is connected in series with two electrode contacts and the coil to form a circuit. The injector indirectly controls the movement of the piston through the electromagnetic push and the controller, so as to realize the purpose of projecting and controlling the dosage.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and relates to a structure of a medical syringe. Background technique [0002] Syringes are used to inject drugs into animals or humans, but sometimes animals or humans (special inconvenient patients such as mental patients) do not cooperate with injections, and long-distance shooting injections are usually required, that is, syringes or needles carrying liquid medicine Use a projection device to inject it into the body of these animals or humans, but such a syringe cannot push the drug like the traditional refraction process, so it carries less medicine and injects less medicine, sometimes unable to meet the dosage requirements , It takes many shots to meet the requirements, which undoubtedly increases the danger, trouble, and brings pain to the injected person. [0003] Chinese patent (notification number: CN209137610U; announcement date: 2019-07-23) discloses a medical syringe. The...
