ABSTRACT:
A urinary catheter comprising an elongated hollow tube having a proximal end, a distal end, a drainage opening in the distal end and a liquid drainage lumen extending from the opening to the proximal end. A valve is located in the lumen near the distal end. Under normal conditions, the valve is open so as to permit urine to pass from the distal end to the proximal end. However, in response to fluid pressure applied to the valve by a cleansing solution on its side nearest the proximal end, the valve will close off the lumen and prevent access to the distal end. An opening for introducing the cleansing solution into the lumen on the side of the valve nearest the proximal end in an amount sufficient to cause the valve to close and to flush contaminants contained in the lumen out the proximal end is provided.
