Department of anesthesia syringe

Technical Field

The utility model relates to a medical anesthesia technical field, concretely relates to department of anesthesia syringe.

Background

Anesthesia is generally considered to be a reversible functional inhibition of the central and/or peripheral nervous system, produced by drugs or other means, which inhibition is characterized primarily by a loss of pain sensation.

In the contemporary medical field, medical staff often perform anesthesia injections for patients by means of anesthesia, but in practical clinical applications, the usage mode and the manufacturing specification of the anesthetic needle are basically the same, the medical staff pushes the booster by hand, the pressure inside the injector is changed by the piston, therefore, the anesthetic is injected, when in specific operation, if the anesthetic injection is performed on the weak part of the skin of a patient (such as eyes), the patient is easy to generate physiological rejection action due to pain during the anesthetic injection, at the moment, a medical staff needs to hold the injector with one hand at the back and push the booster with the other hand to perform the anesthetic injection, in the practical clinical application of the method, the needle head of the anesthetic is difficult to accurately control the injection, and on the other hand, when the anesthetic is injected by the method, the medical staff cannot ensure the actual control of the anesthetic needle if the operation technique is unskilled. Therefore, we propose an anesthesia injector to solve the above problems.
