Abstract
A method for collecting urine from a catheterized ambulatory patient. A flat urinary drainage bag is worn by the patient over the abdomen with the bag suspended from a waist-encircling belt. A urethral catheter has a proximal end communicating with the upper portion of the bag just below waist level and a distal end retained within the patient's bladder. A valve-equipped drain tube extends downwardly from the lower edge of the bag, the valve being manually operable for periodically draining the contents of the bag. An anti-reflux flap valve is disposed within the bag at the inlet thereof for preventing reverse-flow of fluid from the bag back into the catheter. Although the inlet for the bag is disposed above the distal end of the catheter when the device is worn by an ambulatory patient, intraperitoneal pressure on the bladder resulting from normal body actions nevertheless causes urine to flow from the bladder into the abdominal bag.
