  • the receiver 10 or 11 is preferably removable from the hose and may be placed within the housing 30 for transport, such as when carrying the unit to a restroom to dispose of collected waste.
  • the power cord 36 which provides electrical power to the pump/motor, is shown in two different configurations in FIG. 2. Either configuration connects to the pump via a connector 37 inserted into a receptacle 35 which is disposed in the wall of the housing 30, preferably near the location of the pump 12. In the embodiment shown connected to the unit in FIG.
  • the power cord 36 has an adapter 38 which may be received in a cigarette lighter or other 12 volt DC power outlet in a vehicle.
  • the power cord 36 may be provided with a standard plug 39 for plugging into a standard wall outlet in a building to receive 110 volt AC power.
  • the receptacle 35 allows the unit to accommodate either the 12 volt or 110 volt power cord.
  • This power configuration is also shown in the schematic diagram of FIG. 1, and makes the present invention very flexible and adaptable in its use.
  • Power for the unit may be secured from either a 12 volt or 110 volt source, so that a single unit may be adapted for use either in a building such as a hospital or nursing home, or in a vehicle such as a truck or airplane as desired by the user.
  • 12v DC power or 110 v AC power may require power supply transformer means disposed between the receptacle 35 and the motor of pump 12 to convert the available power to that required by the pump, and may involve a separate receptacle 35 specifically adapted for each type of power input .
  • An on-off switch 40 such as a lighted rocker switch, is conveniently provided in the side of the housing 30 to allow the user to easily activate the unit.
  • a switch 41 may be provided on the fitting 18 or other similarly convenient location to allow the user to activate the unit with the same hand that is holding the fitting and receiver.
  • the switch 41 is electrically connected to the pump unit 12 via an electrical cord 42 which follows the path of the tube 14 and enters the housing 30 in the same location as the tube.
  • the present invention requires no flushing fluid, so it is not necessary to maintain a supply of such fluid in order to ensure operation of the unit.
  • the present invention thus overcomes the problems of the prior art by providing a completely portable unit that may be easily and discretely carried from a . truck, automobile, aircraft, or hospital room. It can be maintained as a personal unit for a driver who can remove the unit from the truck cab as he or she would remove a small cooler.
  • the pumping action of the pump provides positive suction which prevents unintended spillage due to bumps or movement.
  • a significant improvement over prior art devices arises with the use of the described "in-line" pump as part of the fluid flow line.
  • the inventor has observed that part of the initial leakage problem is often a result of lack of strong suction upon initial discharge of urine.
  • This low vacuum pressure arises in part from the large, open volume of the container which must be depressurized upon initial start-up of the system in typical prior art devices. Accordingly, there is generally a delay in pressure reduction, which actually increases in vacuum strength as the open volume of the container is reduced with entry of increasing fluid volume.
  • urine flow rate is usually at its highest at commencement of discharge because the bladder is fullest and at highest stress at this point. Accordingly, prior art systems tend to operate at lowest efficiency at the very time when fluid flow is likely to be at its highest.
  • the pump is placed in line with the fluid flow.
  • the small volume of the tube section between the pump and the cup is quickly depressurized.
  • the pump is thus not required to depressurize the full container volume at the initial start up period. Therefore, when the initial flow of urine is released, the suction pressure is at its full value and can quickly respond to even extreme flow rates. In conjunction with the other features of this invention, this helps ensure that no spillage occurs.
  • FIG. 3 illustrates an alternative embodiment of the present invention in which power for the pump is supplied by compressed air such as from the air compressor of a truck or other vehicle.
  • the embodiment of FIG. 3 is essentially the same as that of FIG. 2, except that, instead of having an electric pump as in FIG. 2, the unit has a compressed air hose 50 which provides compressed air to an air driven pump 54.
  • the hose 50 is preferably coupled to the outside of the housing 30 via a standard compressed air hose quick-disconnect coupler 52, and is activated by a mechanical switch 56, also provided in the side of the housing.
  • the mechanical switch is needed because the hose 50 would normally be pressurized continuously whenever the vehicle is in operation, and activation of the pump would require manipulation of a mechanical device such as a valve 55 (see FIG.
  • FIG. 3 is thus more convenient and efficient in using a vehicle's existing power sources, and can also incorporate a more powerful pump (if desired) than is possible with the power available from a 12v cigarette lighter connection.
  • the present invention presents additional advantages which enhance the convenience of use, without significantly increasing costs. For example, the unit is more sanitary than other prior art devices because of the provision of detachable receiving cups for different users.
  • the unit features a portable, easy- to-connect fluid collection bag which is removable from within - the unit itself, so as to be easily emptied in normal sanitary facilities and reconnected, or completely disposed of and replaced by a new bag.
  • the unit can remain in place and connected to a power source while disposal is taking place.
  • This device also eliminates the risk of spillage, and is thus safer because it requires far less attention to use than other devices, allowing a driver to keep his or her attention focused on the road.
