ABSTRACT:
A liquid drainage system comprising, a receptacle having a chamber to receive and collect the liquid. The system has a drip chamber having a vent with a bacteria filter covering the vent, and an annular wall having a lower edge defining a valve seat, with the seat being disposed at an acute angle relative to the horizontal when the receptacle is in an upright position. The system has an anti-reflux valve comprising a sheet of flexible material extending across the drip chamber such that the sheet is sufficiently large to engage against the seat peripherally around the drip chamber. The system has a device for retaining an upper portion of the valve against an upper portion of the seat, such that a lower portion of the valve flexes away from the seat when the receptacle is placed in an upright position, and the lower portion of the valve flexes against the seat when the receptacle is disposed in a horizontal position.
