[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

Embodiment Construction
[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.
[0029] like Figure 1 to Figure 12 As shown, a sterile isolator for experimental animals described in this embodiment includes an isolation bag 2 for isolating the external environment, an air supply device 1 for providing clean air to the isolation bag 2, and an isolation bag 2 for entering and leaving Incoming and discharging disinfection device 3 for automatic disinfection of package 2 materials;
[0030] The incoming and outgoing material disinfection device includes a first shell 31 and a second shell 37 for forming a cylindrical closed space; the first shell 31 and the second shell 37 are rotatably installed inside the first shell 31 and the second shell 37 for conveying and discharging materials. A sterilized sealed material transfer device 32; the ...

The invention discloses an aseptic isolator for experimental animals; it includes an isolation bag for isolating the external environment, an air supply device for providing clean air to the isolation bag, and an inlet and outlet material for automatically disinfecting materials entering and leaving the isolation bag Disinfection device; wherein the input and output disinfection device performs dynamic partition sealing on the housing by rotating the rotor installed on the housing, and sets the carrier body in the sealed space, drives the carrier body to rotate through the rotor, and transfers the material between the feed port and the Transfer between outlets; during the rotation of the rotor, it operates in conjunction with the disinfectant nozzle to realize automatic transfer and disinfection of materials entering and leaving the isolation bag. The rotor is used to seal the shell in partitions and transfer and sterilize the materials in the sealed area, which realizes the automation of material transfer and disinfection, improves the efficiency of material transfer and disinfection, and avoids the leakage and pollution of the isolation bag caused by improper operation during manual operation. , Improved disinfection reliability.
Description
technical field [0001] The invention relates to the field of experimental sterile animal breeding, in particular to a sterile isolator for experimental animals. Background technique [0002] The aseptic isolator is a key equipment used in the field of aseptic animal breeding. It creates a sterile growth environment isolated from the external complex environment for the breeding of sterile animals by means of physical isolation, avoiding the external environment. The interference of pathogens, bacteria, etc. on the growth of sterile animals; the sterile isolator needs to be disinfected for the items that enter the isolator from the outside world, but the current sterile isolator materials entering and leaving the disinfection device need to be located in the disinfection channel and the isolation bag first. The partition between the two is manually closed to isolate the isolation bag from the disinfection device, then manually remove the disinfection cover on the outside of t...
