Inhalation anaesthetic mask

Abstract

The invention relates to the technical field of inhalation anaesthetic equipment, and discloses an inhalation anaesthetic mask which comprises a shell I. The right side wall of the shell I is fixedlyconnected with an air intake pipe, the left side wall of the shell I is fixedly connected with a pipeline I, the pipeline I is fixedly connected with a mask body I, a sealing mechanism is arranged onthe bottom end surface of the mask body I, a condensed water collecting device is further arranged in the mask body I, a reminder device and an anesthetic return flow device are arranged between the mask body I and the shell I, and a mixing device is arranged in the shell I. By reducing the contact area between the bottom surface of a sealing ring and the face of a patient, and when the tension provided by an elastic band is constant, the pressure between the sealing ring and the face of the patient is increased, the risk of anesthetic gas leakage caused by non tight fitting of the mask and the face of the patient due to the face deformation of the hare-lip patient is reduced, the sealing between the mask body I and the face of the patient is enhanced, the anesthetic gas leakage is effectively reduced, and the condition that a surgery is affected caused by the fact that the depth of anesthesia is affected due to insufficient anesthesia dose due to the anesthetic gas leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of inhalation anesthesia equipment, in particular to an inhalation anesthesia mask. Background technique [0002] Inhalation anesthesia is one of the most widely used methods of general anesthesia and general anesthesia. It is highly controllable. The anesthetic gas is inhaled by the patient into the nasal cavity and enters the lungs, and enters the brain through blood circulation, which can effectively reduce the pain of the patient. When the drug supply is stopped, the anesthesia gas will be discharged along with the patient’s metabolism, and the patient will gradually wake up. When performing inhalation anesthesia surgery on cleft lip patients, congenital cleft lip may have different degrees and have different manifestations. Cleft lip means that the upper lip may not see obvious clefts, leading to asymmetry of the nose, and the shape of the nose is different on both sides. Some cleft lip may be combined ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an inhalation anesthesia mask, which has the advantages of good sealing performance, and solves the problem that a part of the anesthesia gas leaks through the gap where the mask contacts the patient's face, and the anesthesia gas is mixed in the air, causing Problems of bodily harm to medical staff performing treatment
