SURGICAL DRAINAGE APPARATUS WITH SUCTION CONTROL AND INDICATION Abstract of the Disclosure A surgical drainage unit is provided for draining fluids from the body of a patient wherein the suction pressure, applied through a suction inlet of the unit to draw fluids into the unit, is controlled and a direct indication of the applied suction pressure is afforded. A device which contracts responsive to an increase in suction in a collection chamber of the unit is equipped with an indicator vane that cooperates with a fixed scale to indicate the amount of movement of the bellows and hence indicate the suction within the collection chamber. A manually adjustable control valve controls the amount of air admitted to the suction line within the unit to thereby control the applied suction.
