AI Technical Summary
In the existing sterile isolation operation device, dirty particles and disinfectants entrained by clean gas are difficult to quickly discharge from the exhaust holes on the side of the equipment, resulting in a risk of retention.
Using a two-stage exhaust structure, the sterilization cavity is divided into a working space and an exhaust space through the first partition plate. Using the inner exhaust valve and a clean air intake device, the clean gas directly entrains dirty particles and disinfectant into the first exhaust area of the exhaust space after flushing in the working space, and then enters the second exhaust area. Finally, it is discharged from the outer exhaust port to form a pressure gradient to achieve rapid discharge.
It effectively reduces the retention time of dirty particles and disinfectants on the equipment, ensuring rapid recovery of the sterile environment.
