[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3The utility model provides a technical solution: an anesthesia mask, comprising a main body 1, a delivery tube 5 arranged at the top of the main body 1, the main body 1 is composed of a cushion 11 and an air bag 12, the cushion 11 is fixed to the surface of the air bag 12, and the air bag 12 ensures the comfort of the anesthesia mask during use, while ensuring that the anesthesia mask fits the patient's face, the top of the air bag 12 is fixed with a mask surface 6, the top of the mask surface 6 is fixed with a fixing seat 4, and a mounting mechanism is provided at the connection between the fixing seat 4 and the delivery tube 5, and the mounting mechanism is composed of a connecting sleeve 41, a groove body 42, and a movable sleeve 43. The connecting sleeve 41 is fixed to the end of the delivery tube 5, the groove body 42 is opened on the inner wall of the top of the fixing seat 4, and the movable sleeve 43 is arranged on the surface of the fixing seat 4. The structure improves the problem that the original delivery tube 5 and the fixing seat 4 are connected by direct engagement during the connection process, and the connection is unstable, which affects normal use. By setting an installation mechanism at the connection between the delivery tube 5 and the anesthesia mask, the connection stability is increased while ensuring the convenience of operation, ensuring normal use, the connecting sleeve 41 is stuck into the inner side of the groove body 42, and the surface of the connecting sleeve 41 is in a fit state with the inner wall of the groove body 42.
