ABSTRACT:
A surgical masking and ventilating system for protecting an operating zone from contaminants emanated by members of a surgical team during an operation. The system includes protective apparel for substantially isolating each member of the surgical team from the environment of the operating zone, a suction tube connecting the apparel of each member to a vacuum manifold, an aspirator adapted to create a vacuum in the manifold and each suction tube connected thereto for drawing away contaminants within the apparel of each member and creating an air flow that maintains the person at a comfortable temperature, and high efficiency filter means for cleaning the air discharged from the aspirator to a contaminant free condition prior to re-entry into the environment of the operating room. The aspirator includes a vacuum motor and blower motor which together more efficiently and quietly maintain a substantial vacuum in the connecting tubes and reliably direct the discharged air through the resistance of the high efficiency filter. The protective apparel is designed so as not to substantially impair movement or vision of the user.
