AI Technical Summary
Existing animal anesthesia masks are prone to anesthetic gas leakage during use, which can affect the laboratory environment and the health of experimenters. At the same time, the inflation volume of electric air pumps is difficult to control, which may cause crush injuries to laboratory mice.
An anesthesia mask with a built-in airbag and inflation structure was designed. The volume of the airbag can be adjusted by manually rotating the ring to seal the mouth and nose of the experimental mouse, preventing leakage of anesthetic gas. The size of the airbag can also be adjusted as needed to avoid harming the experimental mouse.
It effectively prevents anesthetic gas leakage, reduces laboratory pollution, protects the health of experimenters, and avoids crushing injuries to laboratory mice. It is simple to operate and has adjustable controls.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of mask for animal anesthesia, specifically relates to a mask for animal anesthesia. BACKGROUND
[0002] Anesthesia is a basic necessary skill in animal experiment, however we often encounter many problems, such as in the process of anesthesia, experimental mouse dies or experimental mouse wakes up before experiment ends, which not only influences experiment progress, but also makes experimental mouse suffer pain.
[0003] Inhalation anesthesia is also called gas anesthesia, and the volatile or gaseous anesthetic is inhaled into the body through the respiratory tract of the animal to produce anesthetic effect.
[0004] When using gas anesthesia, the mouth and nose of the experimental mouse are generally placed in a circular tube during the experiment, and anesthetic gas is introduced into the circular tube for maintenance anesthesia to prevent the experimental mouse from waking up during the experiment, but the end of the circular tube is open, and the excess medicament in the circular tube will overflow and volatilize into the air from the opening of the circular tube, which not only pollutes the laboratory environment, but also affects the health of the experimenter.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments and accompanying drawings.
[0025] An animal anesthesia mask includes a mask body 1, with a connector 2 at the rear end of the mask body 1 for connecting to an external anesthesia pump and air tube. The connector 2 delivers anesthetic gas and air into the mask body 1 for the laboratory mice to inhale. A bladder 3 is provided on the inner side of the front end of the mask body 1. The edge of the bladder 3 is bonded and fixed to the mask body 1. The bladder 3 itself is made of an elastic material and has a certain degree of deformability, which can be increased or decreased. An air inflator 4 is provided on the outer side of the mask body 1. The air inflator 4 is connected to the bladder 3, and the air inflator 4 and the bladder 3 form a sealed space.
[0026] The piston member is movably arranged in the inflation cavity 4 and is in sealing contact with the inner wall of the inflation cavity 4. The piston member is used to push the internal gas to move between the inflation cavity 4 and the capsule 1. The piston member is moved to adjust the position of the gas, so as to expand or contract the capsule 1, thereby fixing and sealing the mouth and nose of the experimental mouse.
[0027] The push device is movably connected to the cover 1 and is used to push the piston member to move. The push device comprises a rotating ring 5. The inner wall of the rotating ring 5 is provided with an internal thread, and the outer wall of the cover is provided with an external thread 6. The rotating ring 5 is threadedly connected to the cover 1, so that the rotating ring 5 can move forward and backward on the cover 1. The rotating ring 5 is provided with a clamping ring 7 on the side. The clamping ring 7 is fixedly connected to the rotating ring 5. One end of the piston member is arranged in the clamping ring 7 and is movably connected to the clamping ring 7. The piston member comprises a plug body 8 and a connecting barrel 9. The plug body 8 is fixedly connected to one end of the connecting barrel 9. The other end of the connecting barrel 9 is arranged in the clamping ring 7. The other end of the connecting barrel 9 is provided with a convex block 10. The convex block 10 is arranged in the clamping ring 7 and is clamped in the clamping ring 7. The clamping ring 7 can rotate relative to the convex block 10 and is used to push the convex block 10 to move, thereby pushing the plug body 8 to move.
[0028] The inner wall of the cover 1 is provided with an air suction cavity 11. The air suction cavity 11 is provided with an exhaust pipe 12. The exhaust pipe 12 is connected to an external waste gas recovery device. The exhaust pipe 12 is used to recover the anesthetic gas and reduce the air pollution in the laboratory. The air suction cavity 11 is arranged on the inner wall of the cover 1, so that the anesthetic gas entering the cover 1 cannot directly flow out from the exhaust pipe 12, thereby prolonging the residence time of the anesthetic gas in the cover 1.
[0029] The working process of the device is as follows. The mouth and nose of the experimental mouse are inserted into the front end of the cover 1. Then, the operator manually rotates the rotating ring 5, so that the rotating ring 5 moves outward and pushes the plug body 8 to move forward, thereby extruding the air in the inflation cavity 4 into the capsule 3, so as to increase the volume of the capsule 3. Since the capsule 3 is deformable, it can adaptively adjust the shape around the mouth and nose of the experimental mouse, so as to wrap the mouth and nose of the experimental mouse and prevent the anesthetic gas from overflowing. At this time, the mixed gas of the anesthetic gas and the air is introduced into the cover through the connecting head 2, and the external air suction pump is started, so as to recover the gas in the cover 1 and realize the air circulation in the cover 1. The device has the advantages of simple operation and small size. The rotating ring 5 and the cover 1 are connected through threads, so that the adjustment progress is controllable. The volume of the capsule 3 can be adjusted according to the actual situation, and the experimental mouse will not be excessively pressed.
