Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a high-pressure air gun with the functions of suction and aerosol blocking. Background Art

[0002] In the process of cleaning and disinfecting equipment in medical institutions, high-pressure air guns are widely used for cleaning heat-sensitive equipment, appliances and items and drying lumen equipment due to their efficient spraying ability. However, in the process of using high-pressure air guns, the generation and dispersion of aerosols are often encountered, which may contain harmful microorganisms and chemicals. Direct discharge into the environment not only causes pollution, but also poses a threat to the health of operators. At present, operators mainly use masks and face shields for protection. Working in such an environment for a long time will undoubtedly put operators under tremendous health pressure.

[0003] During the operation of high-pressure air guns, the generation of aerosols is inevitable, but traditional high-pressure air guns do not have corresponding aerosol suction and blocking structures, resulting in aerosols being directly discharged into the air, causing environmental pollution and risks to personnel health.
