Local anesthesia device for anesthesia department operation in hospital

Abstract

The local anesthesia device comprises a bottom frame, a bottom plate, a lifting plate and a placement barrel, a rectangular through area is formed in the middle of the bottom frame, a sliding block is fixed to the side, corresponding to a sliding groove of the bottom frame, of the bottom plate, the sliding block is slidably connected into the sliding groove of the bottom frame, and the lifting plate is movably connected to the bottom plate through the action of a limiting rod and a threaded rod; one side of the bottom end of the placement barrel is rotationally connected to the other side of the circular penetrating area through a rotating shaft, limiting plates are fixed to the positions, close to the arc-shaped rods, of the outer side of the bottom end of the placement barrel, arc-shaped through holes are formed in the ends of the limiting plates, and the arc-shaped rods are slidably connected into the arc-shaped through holes; a needle cylinder clamping plate is movably connected into the containing cylinder, and a needle penetrating area is formed in the middle of the needle cylinder clamping plate. According to the injection device, the inclination angle of the containing cylinder can be adjusted according to the injection angle, the height of the lifting plate can be adjusted according to the injection depth, the height of the needle cylinder clamping plate can be finely adjusted according to the injection depth, the efficient and accurate injection process of anesthetics can be completed, and the injection device is efficient and practical.

Description

technical field [0001] The invention belongs to the technical field of local anesthesia auxiliary devices, in particular to a local anesthesia device for hospital anesthesia department operations. Background technique [0002] Local anesthesia, also known as local anesthesia, refers to the application of local anesthetics 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. blocked state. This block should be fully reversible without any tissue damage. The advantages of local anesthesia lie in its simplicity, safety, patient awareness, fewer complications and less impact on the patient's physiological function. [0003] Local anesthetics refer to those drugs that can temporarily, completely and reversibly block nerve conduction within the limited range of the human body, that is, to make a p...

Problems solved by technology

[0004] However, during the implementation of local anesthesia, it is necessary to accurately inject the anesthetic into the area that needs local anesthesia. However, the accuracy of the needle control during the injection of the existing anesthetic is poor, and human factors are greatly affected, which affects the precise implementation of local anesthesia.
