Anaesthetic-concentration-adjustable device

Abstract

The invention provides an anaesthetic-concentration-adjustable device. The device comprises a base; two horizontal pipes distributed up and down are arranged above the base; the horizontal pipe on thelower side is fixedly connected with the base; the two horizontal pipes are fixedly connected; annular partition plates which are symmetrical from side to side are arranged on the middle parts of thehorizontal pipes respectively; the inner side of each annular partition plate and the inner periphery of the corresponding horizontal pipe form a gas storage cavity; the interiors of the annular partition plates are fixedly connected with the gas inlet ends of first one-way valves respectively; first pistons are respectively arranged on the left sides and right sides of the interiors of the horizontal pipes; the inner side of each first piston, the outer side of the corresponding annular partition plate, and the inner periphery of the corresponding horizontal pipe form a gas inlet cavity; thegas inlet cavities and the gas storage cavities are communicated through the first one-way valves; the outer periphery of each first piston is respectively matched with the inner wall of the corresponding horizontal pipe in a sliding contact way; first through holes are respectively formed in the middles of the outer sides of the first pistons. The anaesthetic-concentration-adjustable device is ingenious in design and convenient in use and operation, and can continuously mix anesthetic gas and loaded gas in small batches; the mixing is more uniform; waste caused by residues after mixing of alarge quantity of anesthetic gas is avoided.

Description

technical field

[0001] The invention belongs to the field of medical devices, in particular to an adjustable anesthesia concentration device. Background technique

[0002] Anesthesiology is a comprehensive discipline, which includes multidisciplinary knowledge; now it has a wider scope, not only

[0003] To meet the requirements of the operation, and also participate in the rescue work of various departments, gynecological painless childbirth, painless abortion, etc., it is necessary to perform general or local anesthesia on the patient before the operation, so as to reduce the pain of the patient during the operation; in order to adapt to different Human physique requires continuous adjustment of the anesthetic concentration. The existing anesthetic concentration adjustment device is relatively complicated and inconvenient to operate. It mixes a large amount of anesthetic gas with the loading gas at one time, and the mixed anesthetic gas is wasted when it is not used comple...
