Technical Field

[0001] The utility model relates to the technical field of anesthesia masks, in particular to a sealing inhalant anesthesia mask. Background Art

[0002] The discipline of anesthesiology is a comprehensive discipline that encompasses knowledge from multiple disciplines. Its scope is now broader, not only meeting the requirements of surgeries but also participating in rescue work in various departments, painless childbirth in gynecology, painless abortions, etc. Anesthesia masks are often used when inducing anesthesia in patients clinically.

[0003] In the prior art, when an anesthesia mask is in use, there are gaps between the mask and the patient's face, and anesthetic gas easily flows out of the mask through these gaps, resulting in a reduced practicality of the anesthesia mask.

[0004] To solve the above problems, the prior art is to tighten the rope behind the mask, thereby increasing the contact force between the mask and the patient's skin to reduce the gap between the mask and the patient's face. However, the mask easily leaves marks on the patient's face, causing discomfort to the patient. Summary of the Invention
