ABSTRACT:
A apparatus and method for protecting a patient's area from aerobic contamination comprising a flexible drape assembly adhered to the surrounding area being operated on. The drape assembly includes two sheet members having predetermined cooperative dimensions and joined to each other defining an internal cavity with a plurality of outlet openings through the first sheet member. The internal cavity is pressurized with clean filtered air. The apparatus also includes a suction assembly with inlet ports mounted in the proximity of the area being operated on. A non-preferential turbulence free laminar flow is achieved away from the protected exposed area.
