Abstract
Method for introducing and maintaining a level of negative pressure in a body cavity of at least 80 mmHg using a tube having an elongate distal portion and a proximal portion having first and second arms, each arm having a lumen in flow communication with one another and with the body cavity via apertures at or near the distal end of the tube, wherein the first arm or tubular extension therefrom is adaptable to receive suction from a suction source. An indicator, arranged in relation to the second arm, signals when a specific negative pressure has been exceeded in the tube, or a valve, arranged in relation to the second arm, admits ambient air into the lumen of the second arm when suction is applied to the tube and differential air pressure between the air in the lumens of the tube and ambient air exceeds a specified amount.
