Abstract

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.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 119 words
Apparatus for controlling the disposal of urinary waste from a collection receptacle carried by a wheelchair occupant, said receptacle including a drain tube, comprising: a valve rigidly connected to said wheelchair and selectively positionable to an open or closed configuration; an inlet conduit for said valve connected to said drain tube; an outlet conduit for said valve, said outlet conduit extending from said valve to a location beneath said wheelchair; and means connected to said valve and extending to a position remote from said valve and proximate said occupant for selectively positioning said valve to said open configuration to permit flow of said waste from said receptacle, through said valve and outlet conduit, onto the floor beneath said wheelchair.
Claim 2
Dependent Claim 119 words
Apparatus for controlling the disposal of urinary waste from a collection receptacle carried by a wheelchair occupant, said receptacle including a drain tube, comprising: a valve rigidly connected to said wheelchair and selectively positionable to an open or closed configuration; an inlet conduit for said valve connected to said drain tube; an outlet conduit for said valve, said outlet conduit extending from said valve to a location beneath said wheelchair; and means connected to said valve and extending to a position remote from said valve and proximate said occupant for selectively positioning said valve to said open configuration to permit flow of said waste from said receptacle, through said valve and outlet conduit, onto the floor beneath said wheelchair.
Claim 3
Dependent Claim 43 words
Apparatus for controlling the disposal urinary waste as defined in claim 1 wherein said means for selectively positioning said valve comprises: a lever mounted on said wheelchair and connected to selectively position said valve, said lever extending to a position proximate said occupant.
Claim 4
Dependent Claim 31 words
Apparatus for controlling the disposal of urinary waste as defined in claim 2 wherein said wheelchair includes a footrest, and wherein said valve is connected to the underside of said footrest.
