An improved drainage apparatus for use in pleural aspiration of patients during thoracic surgery. The Apparatus includes three tubes mounted in parallel and connected to one another. A first tube acts as a vacuum input tube; the second tube is a flow monitor tube, while the third tube is filled with water and keeps the vacuum system isolated from the atmosphere.

1. A disposable pleural aspiration device, comprising first, second, and third cylindrical tubes on a base and joined at their upper ends by a cap;on the lower side and along said base, runs a first duct which appears on the upper side of said base through two vertical troncoconical couplings located at each end of said first duct; on the upper side of the base is said first tube, which in turn is in communication with said first duct; a second tube joined by a second duct to the base of a cylindrical chamber; said joinder being made through a first aperture, located in the center of the base of said cylindrical chamber, the inside of the second tube communicates with the atmospheric air through said aperture; said cylindrical chamber being closed by a cap, having a first opening of a size that permits placing said third tube to seal said hole; the cylindrical chamber having a lateral opening near the cap which connects the inside of the second tube to the outside air through the second duct, the lower end of the third tube being occluded by a diaphragm and opposite to the first aperture of the base of said is cylindrical chamber and spaced from the bottom of said chamber; said cap being joined to the upper ends of said first, second, and third tubes along the path between the first and the second tubes, said first duct communicating with the outside by a passing through a second opening on the upper side of said cap; said second opening projecting to the outside at the center of a recess, said second opening having a one-way valve from the inside to the outside; the third tube being fixed to said cap and connected to the first and the second tubes by said second duct; opposite to the joinder of said third tube to the cap is a second aperture, communicating the inside of said third tube communicating with the outside by said aperture, a plug in said second aperture inside the second tube being a sphere for use as a fluxmeter.
