Abstract: A urine drainage system includes a drainage tube and an outer tube extending between an interim container at a distal end and a connector at a proximal end. The drainage tube is also fluidly coupled with a urine collection container. The drainage tube is disposed with a lumen of an outer tube to define a closed annular chamber between the drainage tube and the outer tube. The system further includes an air pump in fluid communication with the annular chamber, where the air pump is configured to define a positive air pressure within the annular chamber. The drainage tube is configured to collapse as a result of the positive air pressure, and during use, collapsing the drainage tube displaces pooled urine within the drainage tube proximally toward the collection container. Different magnitudes of the positive pressure collapse different portions of the drainage tube.
