Abstract

A urine collection device (10) that is made up of a flexible, thermoplastic urine collection bag (20), which receives urine through a molded plastic inlet fitment (30) that is secured to an upper end of the bag 5 and discharges urine through a two-piece molded plastic valve fitment (40) at a lower end of the bag. The inlet fitment, which has no check valve therein, has a series of steps gradually reducing lateral extent as it extends longitudinally from the bag to a free end thereof, and each of the steps extends at a non-perpendicular angle to the longitudinal central axis of the inlet fitment. The bag is also free of any check or flutter valve. The outlet valve fitment has a fixed outer element (42) surrounding an inner element (44) that is rotatable with respect to the outer element to selectively open or close the outlet valve fitment to flow.
