ABSTRACT:
A relief valve for regulating the operation of a surgical suction device comprises a plunger adjustably screwable into a fluid escape channel. A conical tip at the end of the plunger is shaped and dimensioned to progressively obstruct an escape port. Longitudinal grooves along the threaded walls of the plunger provide a passage for the fluid from or toward the escape port.
