Description

Technical Field

[0001] The utility model relates to the technical field of lumen equipment detection, and more specifically to a filtering bellows for checking the cleanliness and dryness of a lumen. Background Art

[0002] In the past, when we checked the cleanliness and dryness of the inner walls of soft and hard tubular instruments with long lumens and small inner diameters before packaging at the disinfection supply center, the common method was to spray a certain amount of 95% alcohol in the lumen, then wrap the front end of the lumen with white gauze, and then blow air with a pressure air gun at the other end. We observed whether there was dirt or blood on the 95% alcohol blown out of the white gauze to determine whether the inner wall of the lumen was clean. The dryness of the tubular instrument was determined when it was blown dry until no liquid or water droplets flowed out.

[0003] During operation, due to the excessive pressure of the pressure gun, the white gauze block is easily blown away, causing the alcohol in the tube cavity and uncleaned dirt, tissue, blood, etc. to splash, which not only pollutes the operating table; the aerosol formed also pollutes the clean environment of the packaging area; the operator is also easily splashed by dirt if he fails to avoid it, and his eyes and skin come into contact with the splashed dirt, and the aerosol containing bacteria is inhaled into the nose, causing occupational exposure. Therefore, a new technical solution is needed to solve the problem. Utility Model Content
