The present invention relates to a sterile animal isolator having a shielded drain hole which enables to maintain excellent aseptic status during surgery by allowing the external air to be safely discharged without being introduced into the outside through the drain port.

As is well known, the isolator has been used to manage experimental animals such as rats, rabbits and pigs in a sterile state. The most important function of the isolator is to isolate and isolate the inside and outside of the isolator and to keep the inside aseptic. To keep. Here, the sterile animal means an animal in which the pathogen does not exist.

However, while using the isolator, the process of supplying the external material to the inside and the internal material to the outside is indispensable. Accordingly, in the aseptic farming of animals, the disinfection and the inside of the isolator are disinfected. The sterilization of incoming air is very important. Typically, the air of the isolator is supplied after being sterilized through the HEPA filter, and all materials introduced into the inside are sterilized and sterilized and then brought into the inside.

These isolators can be largely divided into surgical and breeding and transporting depending on the purpose of use, the aseptic animal surgical isolator associated with the present invention has been recently developed and utilized, the pups delivered through surgery for breeding again It is transported to the isolator for breeding. In particular, in the case of pigs, the uterus containing the offspring is extracted from the mother pig outside the isolator, and the uterus is transferred to the isolator to deliver.
