  • Patent number: 6814719
    Abstract: A female urinary system comprises an appliance including a hollow open top urine receiving body having a peripheral rim for fitting under the urethra. The body includes a receiving portion which would be located below the urethra and which merges into a discharge bowl having a discharge opening leading to an integral downwardly extending discharge tube. The discharge tube preferably has a spiral groove in its outer surface to permit the tube to bend without kinking or otherwise cutting off flow through the tube. The appliance also includes a vent located at the highest portion of the appliance. The vent includes a vent hole extending completely through the wall of the appliance and a vent groove leading from the hole to the spiral groove. The central axis of the urine receiving body is at an obtuse angle with respect to the longitudinal axis of the discharge tube.
