Description
Technical field
The present invention relates to clean operating room equipment, particularly relate to a kind of high efficiency particulate air filter sealing device.
Background technique
Currently, clean operating room is the control for taking degree different microbial contamination using air purity technique, reach
Control the requirement that air purity in space environment is suitable for all kinds of operations；And suitable epidemic disaster is provided, it creates a cleaning and relaxes
Suitable operative space environment.Clean operating room does not require nothing more than the air of high cleaning, and the air into operating room first must be through height
Filter cleaning is imitated, and requires can control the circulating direction of air-flow, that is, uses the ultra-clean device of laminar flow, makes air-flow from cleanliness height
Operative region flow to the low region of cleanliness, and take away and be discharged the dust granules in air-flow and bacterium, laminar flow is that one is thin
Small, thin layer air-flow is conveyed with uniform flow velocity to same direction, and the direction of purifying gas flow is divided into vertical laminar flow and level course
Two kinds of streaming, vertical laminar flow high efficiency particulate air filter is vertically blowed mounted in the surface of operation hospital bed, air-flow, and return air inlet is located at metope
Quadrangle, it is ensured that operating table cleanliness is up to standard, generally mostly uses vertical laminar flow, and effect is preferable, clean operating room be one just
Pressure ring border, air pressure according to its different zones (such as between operating room, sterile preparation, Scrub Room, between anesthesia and surrounding clear area
Domain etc.) cleanliness difference require and it is different.
