In order to achieve the purpose of the utility model, the anus plug for animals comprises a pipeline and an injection chamber, wherein the pipeline comprises an inner solid rod and an outer film; one end of the solid rod is arc-shaped, so that the solid rod is easy to insert and can reduce the damage to the anus and the intestine when being inserted; the film is tightly covered on the solid rod and sealed at a position close to one end of the circular arc, so that a cavity is formed between the film and the solid rod; a section of bag part is arranged at the sealing part of the film, and when the space between the film and the solid rod is inflated or filled with water, an air bag ball or a water bag ball is formed at the sealing part, so that the anus opening is blocked to prevent excrement from being discharged, and the anus plug is prevented from falling out; the other end of the solid rod is connected with a fixing column in the injection chamber; the other end of the fixed column is connected with a spring; the other end of the spring is connected with a piston; one end of the outer wall of the injection chamber is connected with the film, and the other end of the outer wall of the injection chamber is in an open state; the diameter of the outer wall of the injection chamber is slightly larger than the diameters of the fixing column, the spring and the piston; a circle of soft elastic thin layer is arranged at a section of an opening of the outer wall of the injection chamber and can just accommodate the piston; the open end of the outer wall of the injection chamber is provided with a circle of circular ring, so that the piston can be prevented from falling out.

Preferably, medical materials such as natural rubber, silicon rubber or polyvinyl chloride can be used for the solid rod and the film.

Preferably, the material used for the bag part is thinner and more elastic than other parts of the film, so that when the bag part is inflated and filled with water, the bag part can be expanded into an air bag ball and a water bag ball preferentially, and other parts can not be deformed.

Preferably, the ring at the opening end of the outer wall of the injection chamber is made of an elastic substance, so that when the injector with the needle removed injects air or water, the injector head of the injector can be just wrapped, and the phenomenon that the membrane and the solid rod cannot be injected due to air leakage or water leakage is prevented.

The utility model relates to an animal is with anus stopper, insert the anus with the convex one end of solid pole earlier during the use, in submerging the anus until whole bag portion, remove the syringe needle with the syringe, pulling syringe piston suction air or water, insert the opening part of infusion room, and push away the piston of infusion room to no soft elastic substance department, promote the syringe and make air or water get into between film and the solid pole, make bag portion inflation plug up the anus mouth, take out the syringe, make the piston resume to soft elastic substance department because of the effect of spring, plug up the opening, prevent gas leakage or leak.

The utility model relates to an anus stopper for animal has following advantage: can be used for animals in anorectal drug effect experiments, especially mice with small body sizes, is convenient to use and is not easy to cause secondary damage to anorectal.
