Fecha de publicación: 04/12/2018 Fuente: WIPO "pollen" A chest drainage container for withdrawing and collecting certain body fluids from within a patient's chest cavity includes means for tolerating the container being accidentally tipped over. To provide such means, some example containers disclosed in this patent merely involve modifying the plastic injection mold of an existing chest drainage container. In some examples, certain partitions and vents are integrally formed in the container's main body. In the event of a tip-over occurrence, the partitions trap collected fluid within their appropriate collection chambers to help prevent inter-chamber mixing of fluid. During normal operation, the vents enable a pocket of otherwise trapped air to escape from within the enclosed collection chambers as incoming body fluid displaces the air. In some examples, under certain conditions, the vent releases gaseous fluid at a volumetric flow that is about 30 times greater than what the vent releases of liquid fluid during a tip-over event.
