A tip-safe chest drainage unit provides liquid sealed chest drainage. The unit has an enclosure of unitary form constructed of synthetic resin material, defining various chambers including a liquid seal chamber, a drain fluid collection chamber, manometric chambers and various equilibration and relief chambers. A chest drainage tube extends into the seal chamber, which is configured for being normally substantially filled with liquid for submerging the end of the drain tube to provide atmospheric sealing thereof. The fluid collection chamber communicates with the seal chamber for receiving fluids via the seal chamber resulting from chest drainage through the drain tube. The equilibration chambers and various baffles in the enclosure preserve fluid content upon tipping of the unit to maintain the drain tube end submerged in fluid at all times.

A tip-safe underwater chest drainage unit for providing liquid sealed chest drainage, and for providing patient-protected drainage even when tipped over, said unit comprising an enclosure of unitary form constructed of synthetic resin material, said enclosure defining within it a liquid seal chamber

A tip-safe underwater chest drainage unit for providing liquid sealed chest drainage, and for providing patient-protected drainage even when tipped over, said unit comprising an enclosure of unitary form constructed of synthetic resin material, said enclosure defining within it a liquid seal chamber, a chest drainage tube extending into said seal chamber, said seal chamber being configured for being normally substantially filled with liquid for submerging the end of said tube to provide atmospheric sealing thereof, a fluid collection chamber communicating with the seal chamber for receiving fluids via the seal chamber resulting from chest drainage through the drain tube, and characterized by equilibriation means in the enclosure for receiving fluid upon tipping over of the unit to maintain the drain tube end submerged in fluid at all times, including when tipped over, and to permit continued receiving of chest fluids even in a tipped-over condition of the unit, said equilibration means comprising at least a first equilibration chamber for receiving fluid from the seal chamber upon tipping over of the unit and for returning the received fluid to the liquid seal chamber upon returning of the unit from its tipped-over condition to an upright position, the drain tube end being positioned within the seal chamber for remaining below the surface of liquid in the seal chamber when fluid is received in said first equilibration chamber when the unit is tipped over.
