Efficient electronic needleless injector

Abstract

The invention discloses an efficient electronic needleless injector which comprises a handle, a spiral transmission rod, a casing and an injection cylinder, wherein a battery is mounted inside the handle; the casing is mounted on the handle; a motor is mounted inside the casing; a transmission rod is mounted on the right side of the motor; a speed reducer is mounted inside the casing; a shaft stabilizer is mounted outside the spiral transmission rod; an adjusting sleeve is mounted on the right side of the casing; the injection cylinder is mounted on the right side of the adjusting sleeve; a piston is mounted inside the injection cylinder; an injection port is formed in the injection cylinder; heat radiation holes are formed in the surface of the casing; dosage scales are arranged on the surface of the injection cylinder. According to the efficient electronic needleless injector, the injection port is of a needleless structure, so that a medicine can be well injected into a human body,the possibility of wound infection caused by trauma of human bodies can be effectively avoided, and the fear of patients about injection can be greatly alleviated.

Description

technical field [0001] The invention relates to the technical field of syringes, in particular to a high-efficiency electric needle-free syringe. Background technique [0002] A syringe is a common medical device, consisting of a needle barrel with a small hole at the front end and a matching piston rod, used to inject a small amount of liquid or inject it into areas that are inaccessible by other methods or withdraw it from those places , when the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in. Traditional syringes mainly use manual injection, which is cumbersome and consumes a lot of manpower and material resources, and most of the syringes use a needle structure. When injecting with a pillow, it will cause trauma to the human body and cause pain in the human body. Patients develop resistance and even fear of injections, and the wounds of injectio...

Problems solved by technology

Traditional syringes mainly use manual injection, which is cumbersome and consumes a lot of manpower and material resources, and most of the syringes use a needle structure. When injecting with a pillow, it will cause trauma to the human body and cause pain in the human body. Patients develop resistance and even fear of injections, and the wounds of injections may also be infected by bacteria, which will cause huge harm to manpower, and even life-threatening in severe cases.
