 urinalwaders

What is claimed is:

1. A containment device for receiving and containing urine and being capable of direct attachment and support along a leg of an individual between the leg and external forces that would tend to collapse the containment device against the leg, the containment device being configured for use by a person using a float tube, said device comprising:

          a substantially rigid case having opposing inner and outer walls, said inner wall being configured for support against the leg of the individual, said outer wall being configured for counter support against the external forces, said rigid case defining a containment volume between the inner and outer walls for receiving and temporarily containing the urine;
          support means extending between the inner and outer walls for maintaining the containment volume and resisting collapse of the outer wall against the inner wall in response to the external forces;
          a fluid containment compartment positioned within the containment volume;
          inlet means for transporting urine from the individual to the containment compartment; and
vent means disposed in communication with the containment volume between the inner and outer walls for venting air from the containment volume to thereby facilitate receiving and temporarily containment of urine within the containment volume, the vent means comprising a flexible tube configured for extending from the case to a position out of a pair of waders to vent air from the containment area.
