<p>A catheter device for the control of liquid discharge from the urinary bladder, and its use, is described. The catheter device is an elongated flexible tube of elastic material having an inlet opening at a distal end thereof and one or more inflatable balloons secured about the tube spaced from the inlet opening. The balloon retains the catheter at a predetermined position within the urethra while preventing urine to flow about the catheter below the balloon. The tube is provided with a numbered scale printed in a predetermined proximal end portion of the tube to provide a visual indication to a user person of the length of the catheter inserted in the urethra to permit the positioning of the one or more balloons at a desired location in the urethra below the bladder during repetitive removal and insertion of the catheter.</p> |
