Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment products, and in particular relates to an air treatment system for a medical cleaning workstation and a working method thereof. Background Art

[0002] Medical cleaning workstations are specialized equipment used for cleaning and disinfection of medical devices, especially for cleaning and disinfection of medical endoscopes. They are widely used in departments of gastroenterology, anorectal medicine, respiratory medicine, operating rooms, etc. in medical institutions that have endoscopic diagnosis and treatment. Medical cleaning workstations usually include initial washing, secondary washing, rinsing, disinfection, final washing, drying and other steps. During the drying process, high-pressure gas is required for drying. However, most cleaning workstations on the market currently do not perform necessary cleaning treatment on high-pressure gas, resulting in the cleaning cleanliness of endoscopes and other medical devices largely depending on the cleanliness of high-pressure gas, which seriously affects the cleaning effect of medical cleaning workstations.

[0003] For example, a Chinese patent with an authorization announcement date of August 9, 2019 and an authorization announcement number of CN209222756U discloses an endoscope cleaning and disinfection machine, which includes a cleaning sealing groove, a plurality of disinfectant injection pipes connected to the cleaning sealing groove, and an integrated control module. It utilizes ultrasonic cleaning, and adds a blow-drying function after each cleaning process. Alcohol is used for disinfection at the end to reduce the residual cleaning liquid and make the cleaning and disinfection more thorough. This solution also does not perform necessary cleaning treatment on the gas used. Therefore, it is hoped to design an air treatment system for a medical cleaning workstation to specifically clean the gas used in the cleaning process, thereby further improving the cleaning and disinfection effect of medical devices. Summary of the invention
