Abstract

The invention belongs to the technical field of medical instruments, relates to a medical injector structure, and solves the technical problems that existing medical injectors cannot perform projection and control injection doses. The medical injector structure comprises a needle, a needle barrel with a cavity and a piston arranged in the needle barrel in a sliding manner, wherein a piston rod isfixedly connected onto the piston, the piston extends out of the needle barrel from the tail end of the needle barrel, the needle is connected to the front end of the needle barrel in a sliding manner, and a disposable diaphragm is arranged at the front end, close to the needle barrel, in the cavity of the needle barrel; two electrode contacts are arranged on the outer end surface of the front endof the needle barrel, and a metal piece capable of conducting the two electrode contacts is fixedly arranged on the peripheral surface of the needle; the piston rod is made of magnet or a magnetic piece is fixedly arranged on the piston rod, the needle barrel is sleeved with a coil, a battery is fixedly arranged on the needle barrel, and the battery is serially connected with the two electrode contacts and the coil to form a loop. The injector indirectly controls the piston to move through electromagnetic push and a controller, and the purposes of projection and dose control are achieved.

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...
