<p>A urine-collecting container-valve assembly particularly intended for use when taking urine from the urinal bladder of a patient, particularly a bed-ridden patient. The assembly comprises a container, made of thin plastic material, having an inlet port which accommodates a non-return valve arrangement. The valve arrangement is housed in a valve housing having an inlet and an outlet. Arranged in the interior of the valve housing is a perforated plate-like element which extends transversely to the longitudinal axis of the valve housing in liquid-tight abutment with the walls of the housing. The housing also has arranged therein a pressure-activated buoyant body which is freely movable between the mutually opposing surfaces of the plate-like element and the bottom wall of the valve housing. The invention is characterized by means which co-act with the buoyant body in a manner to guide the body axially during its movement from one terminal position to another terminal position.</p> |
