Gas anaesthetic mask

Abstract

The invention discloses a gas anaesthetic mask. The gas anaesthetic mask mainly comprises an outer frame, a converter, a cleaner, reinforcing ribs, a cannula frame and a rubber ring. The gas anaesthetic mask is reasonable in structural design, a T-shaped belt and a head binding belt can be matched with the rubber ring with the reinforcing ribs, the supporting strength can be guaranteed while pressing is carried out, the pressing tightness is guaranteed, and leakage is avoided; meanwhile, a first blocking frame and a second blocking frame inside are matched with a second cover plate and a second cover plate, the structure is compact, double-channel flowing gas supply is realized, meanwhile, opening and closing are stable, and the sealing performance is good; the cleaner which is rapid to disassemble and stable in inserting and sealing is arranged inside, rapid disassembly and assembly can be carried out, the internal cleaning is guaranteed, the replacement is convenient, the bacteria breeding is avoided, and the maintenance cost and steps are reduced; and meanwhile, the converter is arranged, so that flexible conversion between oxygen and anesthetic gas can be carried out, instant and rapid gas supply conversion is realized, moreover, the equipment is double-pipe flowing gas, the gas inside the outer frame can be rapidly replaced, the precision of the anesthetic material is guaranteed, and the requirement for doctors is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a gas anesthesia mask. Background technique [0002] Anesthesia is a variety of methods used to eliminate pain, ensure patient safety, and create good surgical conditions during operations or diagnostic inspections, and is also used to control pain. During a surgical or diagnostic test, the patient experiences pain and needs to be temporarily rendered unconscious with anesthesia or other means. Surgery or inspection operations can also cause mental stress and reflex adverse reactions, such as gastrointestinal surgery can cause nausea and vomiting. Prolonged uncomfortable positions (such as prone position) can increase the patient's discomfort and pain. Therefore, patients should be operated in a comfortable and quiet environment without any response to adverse stimuli and temporary loss of memory. [0003] The structure of the existing anesthesia mask is simple, with an air bag, which is in...
