Mask for gaseous anesthesia and anesthesia device

Abstract

The invention belongs to the technical field of gaseous anesthesia equipment, and particularly relates to a mask for gaseous anesthesia and an anesthesia device.The mask for gaseous anesthesia comprises an inner mask body, an outer mask body is arranged outside the inner mask body, the outer mask body comprises an elastic framework rod and a telescopic curved mask body installed on the framework rod, and the outer mask body is provided with a large opening and a small opening; the size of the large opening is larger than that of the small opening, the small opening is sleeved with a size adjusting pipe, the inner mask body, the outer mask body and the face attaching mask are connected through a gas guide pipe, and the part, located outside the size adjusting pipe, of the gas guide pipe is used for being connected with an anesthetic gas providing machine. The inner mask body and the outer mask body have double anesthetic gas blocking effects, and nose inhalation and mouth inhalation are double anesthetic gas absorbing effects, so that waste and leakage of anesthetic gas are not caused, environmental pollution is avoided, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of gas anesthesia equipment, in particular to a gas anesthesia mask and an anesthesia device, and more particularly to a gas anesthesia mask and an anesthesia device that can reduce gas loss. Background technique [0002] Anesthesia is the use of drugs or other methods to reduce the pain of the patient to relieve the pain of the patient and achieve the purpose of painless treatment. Common clinical anesthesia methods are drug anesthesia or gas anesthesia. Common gas anesthesia drugs include isoflurane, desflurane, sevoflurane, etc. Gas anesthesia has the characteristics of short induction period and quick recovery. At present, the anesthesia devices used in conjunction with gas anesthesia include gas anesthesia masks, air tubes, anesthetic gas supply machines containing anesthetic gas, and auxiliary facilities such as oxygen tanks. Gas anesthesia masks, air tubes, and anesthetic gas supply machines are conne...

AI Technical Summary

Problems solved by technology

[0003] However, since the existing gas anesthesia mask is only a mask body connected to the airway, the size of the mask body is not adjustable and cannot fit patients with different face sizes, so there is a risk of anesthesia gas leakage. Although the existing technology There are technologies to improve the structure of the mask, but they all add a negative pressure device to prevent leakage and a gas anesthesia mask to absorb anesthesia gas outside the ordinary mask. The absorbed anesthesia gas is not used by the patient, and it still needs to go through professional procedures. The processing system carries out processing, resulting in resource fees, which is not conducive to environmental protection
