ABSTRACT:
A method and apparatus for aspirating fluids from a surgical operating room utilizing a suction head that readily slides along the floor in response to translational forces applied by foot by operating room personnel. The suction head has a flat bottom surface with a plurality of narrow flow channels defined therein between a suction port mouth and the surface periphery. Support ribs, disposed on the top surface in juxtaposed alignment with respective flow channels, impart strength to the suction head and prevent sealing of the flow channels. The suction head is adapted to operate with suction sources commonly available in surgical operating rooms operating through a fluid waste collection chamber. The flow channels conduct fluid to be aspirated while preventing the bottom surface from becoming sealed to the floor.
