ABSTRACT:
A urine collection container carried by a person confined to a wheelchair includes a drain tube which is connected to a valve mounted on the person's wheelchair to permit the person, unattended, to empty the contents of the collection container onto the ground or into a floor drain beneath the wheelchair. The valve may be manually operated, as by a lever within reach of the wheelchair occupant, or may be operated using a solenoid. The latter construction permits remote operation of the valve utilizing a low current sensitive switch operable, for example, by a quadraplegic. In addition, the solenoid operated valve permits the use of a timing circuit which automatically closes the valve a predetermined period of time after the valve is open to prohibit the valve from accidentally being left open and additionally to permit handicapped persons to both open and close the valve with a single switch operation.
