The living environment requirements for sterile animals during long-distance transportation are even more stringent. Not only do we need to provide sterile animals with a suitable living environment, but we also need to keep the living environment of sterile animals in a sterile state to prevent them from being contaminated by external microorganisms.

In the prior art, when sterile animals are transported over long distances, a cylindrical soft film transport isolation sleeve with a diameter of 330 mm and a length of 1240 mm is generally used to connect to the isolator. After the transport isolation sleeve is connected to the isolator, the packaged animal cage is transferred from the isolator to the sleeve, and then the sleeve is operated to support the sleeve connection port with the disc-shaped air filter in the sleeve, so as to achieve a sealing effect and also exchange the air with the outside world in a sterile manner. However, during long-distance transportation and up and down handling, the transport isolation sleeve made of soft film material is easily damaged, so that the sterile animals in the cage are exposed to the external environment and contaminated by external microorganisms.
