Adjustable spraying device for local anesthesia in anesthesiology department

Abstract

The invention discloses an adjustable and controllable spraying device for local anesthesia in the anesthesiology department. The adjustable and controllable spraying device comprises a bottom plate, universal wheels are fixedly installed on the two sides of the bottom of the bottom plate, an equipment box is fixedly installed at the top of the bottom plate, a U-shaped frame is fixedly installed at the top of the equipment box, and an electric telescopic rod is fixedly installed in an inner cavity of the U-shaped frame. According to the adjustable and controllable spraying device for local anesthesia in the anesthesiology department, a third driving motor drives a second lead screw to rotate, under the threaded transmission action of the second lead screw and a transmission base, the transmission base drives an L-shaped connecting pipe to reciprocate front and back, and then an atomizing nozzle is driven to reciprocate front and back; according to the anesthetic spraying device, the atomizing nozzle moves at a constant speed and sprays anesthetic to a patient, the atomizing nozzle is mechanically driven to move, the anesthetic can be evenly sprayed to an operation area of the patient, the situation that the anesthetic is too much in part of the area and too little in part of the area is avoided, and the anesthetic effect is good.

Description

technical field [0001] The invention relates to the field of anesthesiology, in particular to an adjustable spray device for local anesthesia in the anesthesiology department. Background technique [0002] It is generally believed that anesthesia is a kind of reversible functional inhibition of the central nervous system and (or) peripheral nervous system produced by drugs or other methods. The main feature of this inhibition is the loss of sensation, especially pain sensation. [0003] As the name suggests, anesthesia means numbness and numbness, and drunk means drunken coma. Therefore, the meaning of anesthesia is to use drugs or other methods to temporarily deprive the patient of the whole or part of the sensation, so as to achieve the purpose of painless surgical treatment. Anesthesiology is a science that uses basic theories, clinical knowledge and techniques related to anesthesia to eliminate surgical pain, ensure patient safety, and create favorable conditions for su...

[0005] This application improves the prior art. The spraying device in the prior art adopts the method of spraying the anesthetic on the skin surface of the patient by using a manual hand-held spray bottle or nozzle, but manual hand-held spraying cannot guarantee The skin area to be sprayed is evenly sprayed, and it is easy to spray less local medicine, resulting in pain before the operation is over
