Anesthetic waste gas extraction device with filtering structure for anesthesia department

Abstract

The invention relates to an anesthetic waste gas extraction device with a filtering structure for an anesthesia department. The anesthetic waste gas extraction device comprises a mounting plate, a hydraulic cylinder and a fixing block; a positioning bolt is arranged at the top end of the mounting plate, a waste gas bottle is arranged on one side of the mounting plate, a bolt disc is arranged at the top end of the waste gas bottle, and an inner bottle is arranged at the bottom end of the interior of the bolt disc; a sealing plate is arranged at the bottom end of the inner bottle, a sealing ringis arranged at the bottom end of the waste gas bottle, an exhaust pipe is arranged at the bottom end of the sealing ring, and clamping groove bolt discs are arranged on the two sides of the exhaust pipe. The anesthetic waste gas extraction device has the beneficial effects that the lifting frames can be pushed by power of the hydraulic cylinder, the piston plate between the lifting frames is driven to do reciprocating lifting motion between the filter bottles, waste gas in the exhaust pipe is effectively adsorbed to pass through the purification filter screens, impurities in the waste gas canbe filtered in the purification filter screens, the flowability of the reciprocating adsorption gas can be improved by power of the hydraulic cylinder, and the waste gas treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of anesthesia waste gas extraction devices, in particular to an anesthesia waste gas extraction device with a filtering structure for anesthesia departments. Background technique [0002] The anesthesia waste gas extraction device is mainly used in anesthesia machines. The anesthesia machine uses low-flow anesthesia mixed gas to supply patients with one-way flow through the escape valve, and the exhaled gas enters the CO2 absorber through the exhalation valve for reuse. Its structure is mainly It is composed of oxygen supply and nitrous oxide device, gas flow meter, evaporator, CO2 absorber; one-way valve, breathing circuit, escape valve, air storage bag, etc. However, there are foreign matter defects in the anesthesia waste gas extraction device, which affects To ensure the normal operation of the anesthesia machine, it is necessary to improve the structure of the anesthesia waste gas extraction device. ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an anesthesia waste gas extraction device for anesthesia departments with a filtering structure, so as to solve the anesthesia waste gas extraction device on the market proposed in the above background technology, the pressure of the gas circulation place is too low, and the impurity filtration effect is not good , serious bacterial residues inside the pipeline, poor sealing effect at the joints, inconvenient handling after filtering foreign matter, and affecting the effect of the anesthesia exhaust gas extraction device
