Description of the embodiments
Referring to fig. 1-5, the utility model discloses an anesthesia maintenance mask for a laboratory mouse, which comprises a breathing tube 1 with a tube joint 11, wherein a neck cover of the breathing tube 1 is provided with a neck cover assembly 2, the neck cover assembly 2 comprises an annular fixing ring 21, the annular fixing ring 21 is arranged on the breathing tube 1 in a sealing way, a rubber membrane ring 22 made of a rubber film and worn on the neck of the laboratory mouse is arranged on the annular fixing ring 21, and a middle hole of the rubber membrane ring 22 is a wearing hole 221 for the head of the laboratory mouse to pass through and be matched with the neck of the laboratory mouse. The hole edge of the wearing hole 221 is designed by adopting an arc-shaped thickening ring 2211 so as to improve the strength of the wearing hole edge and improve the tightness of the wearing hole after the experimental mouse is worn. The mouth of the breathing tube is covered by a rubber film and sleeved on the neck of the laboratory mouse, and the rubber film has better elasticity, so that the laboratory mouse can conveniently pass through and seal with the neck of the laboratory mouse, and the leakage of anesthetic is reduced. The breathing cylinder 1 is a perspective structural member made of transparent materials, so that the state of an experimental mouse can be observed conveniently.
The rubber membrane ring 22 is integrally formed with annular, corrugated elastic deformation folds 222. The head of laboratory mouse is wearing in wearing the hole, and the head position can not necessarily with wear the center in hole unanimous, and this can exist the laboratory mouse and can lead to the fact radial traction to the rubber film, and influence the laminating degree of wearing hole and laboratory mouse neck, consequently set up elastic deformation fold for the radial extension that the rubber membrane circle can be better, thereby the skew that adaptation laboratory mouse's head position probably appears guarantees that the laboratory mouse reliably wears in wearing the hole, avoids laboratory mouse head skew to cause to wear hole edge traction and can not reliably seal.
