Abstract

The utility model provides an injection booster, which belongs to the field of the medical injector accessory technology. The utility model provides the injection booster which has simple structure and labor saving injecting operation. The technical proposal is that the utility model comprises two connecting plates and an elastic pulling strip which is connected with the two connecting plates. One of the connecting plates is provided with a via-hole which is passed through by an injector pinhead. The number of the elastic strip is two to four and the elastic strips are arranged around the connecting plate with intervals. The utility model is simple in structure and convenient in operation. When in use, the two connecting plates are respectively placed at the two ends of the injector. The liquid medicine is injected into human body by an injector core driven by the pulling force of the elastic pulling strip. The operation staff uses two hands to cooperate with the instrument. The injection speed can be controlled according to the requirement. Using the booster saves operation labor and can greatly reduce the labor intensity of injection work for medical staff. In addition, the liquid medicine can be injected into the body of patient at uniform speed.

Description

The injection booster

Technical field

This utility model relates to a kind of injection booster, belongs to the accessories of medical syringes technical field.

Background technology

At present, medical personnel still adopt traditional syringe, and armrest promotes, and injecting liquid drug is arrived in patient's body.Under the less situation of patient, medical personnel also can finish injection work like a cork, but wait under the quiet situation about pushing away a large amount of patients, medical personnel work together just very painstaking, labor intensity is big, and two handss can be felt ache, and injection speed also can be affected.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, injection operation labour-saving injection booster.

The alleged problem of this utility model is solved by following technical scheme:

A kind of injection booster, it comprises two connecting plates and is connected in two elastic drawstrings between connecting plate, and one of them connecting plate is provided with the through hole that passes for syringe needle, and elastic drawstring is two to four, and is provided with along the connecting plate circumferential interval.

Above-mentioned injection booster, said elastic drawstring is elastic rubber band or cylindroid helical-coil extension spring, is distributed between two connecting plates.

Injection booster provided by the utility model is simple in structure, easy to operate.During use, two connecting plates are placed the two ends of syringe respectively, and by means of the pulling force of elastic drawstring drive piston with injecting liquid drug in human body.Operator with the hands cooperate with this apparatus, can control injection speed as required.Use this booster rapid operation, can reduce the labor intensity that medical personnel inject work greatly, and medicinal liquid is at the uniform velocity injected in patient's body.
