Abstract

The invention relates to a pain-preventing syringe, in particular to a syringe for painless oral local anesthesia, and solves the problems that the traditional local anesthesia by manual injection causes intense piercing pain and injection pain and makes a patient to be in fear of injection, feel anxiety, be unwilling for treatment, and even give up the treatment mentally. The syringe comprises a needle, a tube, a quick connector, a battery, a shell, a motor, a reducer, a coupling, a screw, a screw nut, and a push rod. One end of the needle is connected with one end of the tube, and the other end of the tube is connected with one end of the shell. The battery is disposed inside the other end of the shell and is connected with the motor. A motor rotary shaft is connected with the reducer which is connected with one end of the screw through the coupling, and the other end of the screw passes through the screw nut to be connected with one end of the push rod. The other end of the push rod is connected with a piston rod at the other end of the tube. The screw nut is fixedly mounted in the shell. The syringe is applicable to the field of medical science.

Description

technical field [0001] The invention relates to a painless injection device, in particular to a painless oral cavity local anesthesia injection device. Background technique [0002] Oral disease is a common disease among people, and oral local anesthesia is a commonly used method in oral surgery. At present, the department of stomatology has been following the traditional local anesthesia method of manual injection for the preparation of the abutment teeth of the vital pulp. Due to the strong puncture pain and injection pain, patients often have injection fear, nervousness and anxiety, and are unwilling to see a doctor. , and even give up the psychology of treatment. Especially for patients with systemic diseases such as hypertension and coronary heart disease, the pain and tension during injection can lead to serious complications. Contents of the invention [0003] In order to solve the traditional manual injection local anesthesia method, there are relatively strong p...
