ABSTRACT:
A drainage bag (for example a urine collection bag) (10) includes a flexible outlet tube (16) and a pinch valve (18) for selectively pinching the tube closed. The pinch valve includes a pivotal valve member (22) on a first side of the bag, and a support member (20) on an opposite side of the bag. The valve member is pivotally supported on the first side by at least one projection (26) on the support member which projects through an aperture (24) in a web of the bag. During assembly, the support member (20) is firstly fitted to the bag with the projection (26) projecting through the aperture (34), and the valve member (22) is then fitted to the projection (26). In an alternative form, the support has two hook-shaped projections on either side of the outlet tube (16) to which a modified valve member is clipped.
