ABSTRACT:
A medical fluid suctioning device for selectively applying varied levels of suction pressure at a device-tissue interface includes a direct "trumpet"-type control mechanism in conjunction with a "venturi"-type control. A valve manifold is adapted to couple a vent pathway and a suction pathway simultaneously to the vacuum conduit adapted for connection to a vacuum source. The amount of resistance to flow due to vacuum pressure is adjusted simultaneously in both the vent pathway and the suction pathway in order to achieve controlled, selected levels of suction. Similarly shaped valve apertures are provided in inverse and reciprocal orientation along an axis of motion of a valve manifold. The apertures translate across ports to the suction and venting pathways simultaneously to vary applied suction to those pathways inversely. The shaped valve apertures preferably have diminished elliptical shapes having an elongate axis with an increasing cross-sectional area going from a transverse short axis to a transverse wide axis along the axis of motion of the valve manifold. The diminished elliptical shapes are inversely oriented relative to each other as regards the positioning of their wide and short transverse axis along the axis of motion.
