  • Patent number: 4270231
    Abstract: A portable male urinal for use by bed-ridden patients is shown furnished with a drain hose to empty the contents of the urinal by gravity into a lower collection bag or receptacle. The end wall of the urinal has a recessed wall portion that supports a drain spout. A drain hose may be joined to the spout. The end wall has side notches for receiving the drain hose therethrough so the urinal may be supported upright on its end wall during non-use of the urinal. Other advantages are several species of closure means for the drain spout, elongated anchor means along the sides of the urinal for fastening the urinal to the user, and baffle means positioned within the urinal to discourage backflow of the contents.
