  • Urinary drainage bag
    Patent number: 4085755
    Abstract: The specification describes a fluid drainage bag having first and second plies, a fold in the first ply, and a drainage opening closed by a flap valve in the fold. The fold is held open by means of a flexible drainage tube maintained in a flexed position between the fold and the upper end of the bag. The opening of the fold draws the flap valve away from the second ply so that it does not stick in the open position to the second ply.
