Abstract

The local anesthesia device comprises an injection cylinder, a first sliding groove is formed in the front side of the outer wall of the injection cylinder in the vertical direction, and a second sliding groove is formed in the rear side of the outer wall of the injection cylinder in the vertical direction; the injection needle is detachably connected to the bottom end of the injection cylinder in a sleeving manner; the protective sleeve sleeves the outer wall of the injection needle, and the top end of the protective sleeve is arranged at the bottom end of the injection cylinder; the spring is sleeved on the outer wall of the protective sleeve, and the top end of the spring is clamped at the bottom end of the syringe. According to the device, the insertion depth of an injection needle can be fixed, the injection needle is prevented from being pushed to move forwards in the medicine pushing process, then anesthetic medicine can be prevented from being injected into blood vessels, finally, medicine poisoning of a patient is prevented, and potential safety hazards are eliminated; the injection needle can be prevented from being scratched or inserted into the hand of the medical staff in the needle withdrawing process of the medical staff, cross infection is prevented, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a local anesthesia device for an anesthesiologist. Background technique [0002] Local anesthesia, also known as local anesthesia, refers to the application of local anesthesia to parts of the body when the patient is conscious, so that the sensory nerve conduction function of a certain part of the body is temporarily blocked, and the motor nerve conduction remains intact or at the same time to varying degrees. In the blocked state, the block should be completely reversible without any tissue damage. The advantages of local anesthesia are that it is easy to operate, safe, the patient is awake, the complications are few, and the impact on the patient's physiological function is small; [0003] When performing local anesthesia on a patient, it is necessary to inject intramuscularly into the area where the patient needs anesthesia. During intramuscular injection, in order ...
