SELF-ADJUSTING SUCTION REGULATOR Abstract of the Disclosure A suction regulator is provided for a pleural drainage device which includes a spring-loaded valve which opens to atmosphere to maintain the appropriate suction levels in the pleural drainage device together with an air flow regulator which reduces the air flow to the drainage device when the suction level from the suction source exceeds a predetermined level. A tapered passageway is provided in the air flow path from the suction source to the pleural drainage device and a ball valve having an opening therethrough is slidably disposed within the tapered passageway so that when the air flow through the passageway increases, the ball valve rises to decrease the amount of air passing through the passageway.
