Abstract: Tubular catheter adapter for use in a urinary drainage system comprising first and second tubes joined by a tubular sleeve having a filtered aperture in its sidewall at a location protected and remote from the normal flow path of urine through the adapter. The filtered aperture is covered by a bacteria filtering material through which air can pass, but body fluids cannot, thereby forming a filtered air vent in the sidewall of the adapter.
