[0002] The aseptic isolator is a key equipment used in the field of sterile animal breeding. It creates a sterile growth environment isolated from the complex environment of the outside world for the breeding of sterile animals by means of physical isolation, avoiding contamination in the external environment. Pathogens, bacteria, etc. interfere with the growth of sterile animals; aseptic isolators need to be disinfected for items that enter the isolator from the outside, but the current aseptic isolator materials entering and leaving the disinfection device need to first separate the disinfection channel and the isolation bag. The partition between them is manually closed, so that the isolation bag is isolated from the disinfection device, and then the disinfection cover outside the disinfection channel is manually removed, and the items are placed in the disinfection channel, and then the items in the disinfection channel are manually cleaned after the outer cover is closed. Spray disinfectant for disinfection. After the disinfection is completed, open the partition and send the items into the isolation bag; when taking out the items from the isolation package, the above operations are also required. Since the disinfection process is completely manual, the isolation package needs to be sealed and unsealed. The process is complicated, and the operation is not standardized, which can easily lead to incomplete disinfection of items or lax sealing of the isolation package, allowing external pathogens and bacteria to enter the interior of the isolation package, causing sterile animals to be contaminated by external microorganisms; therefore, the development of a simple, efficient and convenient , Disinfection, safe and reliable automatic feed-in and discharge-disinfection sterile isolator for experimental animals is very necessary

The invention discloses a sterile isolator for experimental animals. The sterile isolator comprises an isolation bag used for isolating the external environment, an air supply device used for providing clean air for the isolation bag and a feeding and discharging disinfection device used for automatically disinfecting materials entering and exiting the isolation bag; wherein the feeding and discharging disinfection device performs dynamic partitioned sealing on a shell through a rotor rotationally installed on the shell, a carrier body is arranged in a sealed space, the carrier body is driven to rotate through the rotor, and materials are transferred between a feeding port and a discharging port; and the rotor is matched with a disinfectant nozzle for linkage operation in the rotating process, so that automatic transfer and disinfection of the materials entering and exiting from the isolation bag are realized. The shell is sealed in a partitioned mode through the rotor, the materials are transferred and disinfected in the sealed area, automation of material transferring and disinfecting is achieved, the material transferring and disinfecting efficiency is improved, meanwhile, leakage pollution of the isolation bag caused by misoperation in the manual operation process is avoided, and the disinfecting reliability is improved.
