Abstract

A system, method, and apparatus for administering fluids to body cavities, suctioning or aspirating fluids from body cavities, performing gastric decompression, and containing gastric reflux. An exemplary system includes a Y-connector, a multiple lumen tube, and an anti-reflux valve. The Y-connector comprises a delivery arm, a suction arm, and a convergence arm, all in fluid communication with one another and may be coupled to the multiple lumen tube. The multiple lumen tube includes a first lumen, a second lumen, and a plurality of openings. The anti-reflux valve includes a valve adapted to prevent the fluid from flowing beyond the proximal end of the second lumen.
