Abstract

The invention discloses a dental anesthetic injector, and relates to the field of medical equipment. A needle cylinder of the dental anesthetic injector is internally provided with a rubber plug. Therubber plug is connected with a push rod and a pressing sheet. The front end of the needle cylinder is provided with a needle tubing. A section of bellows is arranged on the middle part of the needletubing. The outer wall of the needle cylinder is sleeved with a lantern ring. The lantern ring is connected with a reflector through a connecting rod. When the dental anesthetic injector is used, liquid anesthetic is filled into the needle cylinder, a doctor can hold the needle cylinder by a hand, and the shape of the needle tubing can be flexibly changed according to a patient gingival position,and the doctor bends the connecting rod to adjust the reflector, to conveniently observe an injection site of a patient mouth. Then the needle tubing pricks, the pressing sheet is pressed, and the push rod is pushed to perform anesthetic injection. The whole operation process is very convenient and safe, and the dental anesthetic injector improves injection accuracy of intraoral anesthetic.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a dental anesthetic injector. Background technique [0002] Dentists often inject local anesthetics into the patient's gums before performing dental operations such as tooth extraction to reduce pain during the operation. It is often very troublesome to use a common syringe to inject anesthetics into the gums in the mouth. Since the patient's gums are in different parts of the mouth, and the existing syringes cannot be deformed, nurses need to adjust different actions to complete the anesthetic injection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dental anesthetic injector, which can flexibly change the shape of the needle tube according to the patient's gums, so as to facilitate the injection of anesthetics to the gums, and has a mirror to facilitate observation of the entire injection process. [0004] In o...
