Abstract

A pump (102) comprising a chamber (108) adapted to receive a penis, a non-return valve (156), and pumping means (110) operable to pump fluid from the chamber (108), wherein the pump (102) is adapted for use under water.

Claims

1. A pump comprising a chamber adapted to receive a penis, a non-return valve, pumping means operable to pump fluid from the chamber, and sealing means operable to seal the pump onto the body of a user, the sealing means comprising a cut away section on a face thereof, which seals against the body of a user, when in use.

2. A pump according to claim 1, wherein the chamber is substantially circular in section.

3. A pump according to claim 1, wherein the chamber is transparent.

4. A pump according to claim 1, wherein the chamber comprises a neck section toward a second end thereof, which comprises an outlet.

5. A pump according to claim 1, wherein the pump comprises a cap section within which is accommodated the non-return valve.

6. A pump according to claim 4, wherein the cap section is adapted to fit over the neck section and form a fluid tight seal therewith.

7. A pump according to claim 1, wherein the pump is a penis pump.

8. A pump according to claim 5, wherein the non return valve is adapted to allow the expulsion of fluid from the chamber, but not the ingress of fluid into the chamber.

9. A pump according to claim 5, wherein sealing means are provided between the cap section and the neck section.

10. A pump according to claim 5, wherein the cap section is adapted to be screwed onto the neck section.

11. A pump according to claim 1, wherein the pumping means is situated toward a first end of the chamber.

12. A pump according to claim 1, wherein the pumping means is manually actuated.

13. A pump according to claim 1, wherein the pumping means extends from a first end of the chamber.

14. A pump according to claim 1, wherein the pumping means comprises a compressible gaiter.

15. A pump according to claim 1, wherein the pumping means comprises a resilient bias operable to return the pumping means to an uncompressed configuration.

16. A pump according to claim 1, wherein the sealing means is situated at a first end of the pump.

17. A pump according to claim 1, wherein the sealing means comprises a sealing ring which is made from closed cell rubber sponge or similar.

18. A pump according to claim 1 which further comprises pressure release means.

19. A pump according to claim 18, wherein the pressure release means comprise a plug which is accommodated in an aperture in a wall of the chamber.

20. A pump according to claim 1, wherein, the pumping means further comprises a gas filled chamber.

21. A pump according to claim 20, wherein the gas filled chamber is annular in shape.

22. A pump according to claim 20, wherein the gas filled chamber is attached to an inner face of the sealing ring.

23. A pump according to claim 20, wherein the gas filled chamber is operable to be compressed by the application of pressure by a user.

24. A pump according to claim 20, wherein a spring return force of the gas filled chamber is greater than the resilient bias of the gaiter.

25. A method of causing or enhancing an erection of a human penis comprising immersing a pump as defined by claim 1 in water, placing a flaccid penis into a chamber of the pump and using pumping means to pump water from the chamber through a non-return valve.
