Abstract

A pump (102) comprising a chamber (108) adapted to receive a penis, a non-return valve (152), and pumping means (110) operable to pump fluid from the chamber.

Claims

1. A pump comprising:

a chamber adapted to receive a penis;

a non-return valve; and

pumping means operable to pump fluid from the chamber, wherein the pumping means comprises a compressible gaiter, wherein the pumping means further comprises an internal membrane that is secured over an inner side of the gaiter and is operable to provide a substantially smooth surface inside the gaiter.

2. A pump according to claim 1, wherein the pump comprises a lower portion operable to be arranged proximal to a body of a user, in use, and an upper portion connected to the lower portion.

3. A pump according to claim 1, wherein the pump further comprises rotatable volume adjusting means operable to adjust volume within the pump by rotation.

4. A pump according to claim 3, wherein the rotatable volume adjusting means is operable to adjust the volume within the pump by rotation thereof relative to the chamber.

5. A pump according to claim 3, wherein the rotatable volume adjusting means is situated at or toward an end of the pump.

6. A pump according to claim 5, wherein the rotatable volume adjusting means is situated at or toward an end of the pump arranged to be distal to a body of a user, in use.

7. A pump according to claim 3, wherein the rotatable volume adjusting means comprises a rotatable section and a stationary section that are arranged and operable for relative rotation, in use.

8. A pump according to claim 7, wherein relative rotation of the rotatable section and the stationary section causes the two sections to move relative to each other in a direction generally perpendicular to an axis of rotation of the rotatable section.

9. A pump according to claim 1, which further comprises secondary pumping means at or toward an end of the pump operable to be arranged distal to a user, in use.

10. A pump according to claim 9, wherein the secondary pumping means comprises a body that is resiliently biased.

11. A pump according to claim 9, wherein the secondary pumping means is operable, in use, to eject very small amounts of fluid from the chamber.

12. A pump according to claim 1, which further comprises means to allow the pump to attach to a strap.

13. A pump according to claim 1 which further comprises a cap section within which is accommodated the non-return valve, the non-return valve comprising a pressure release button which, upon depression thereof, allows equalisation of pressure within the chamber and pressure outside the chamber.

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

15. A pump according to claim 1, which further comprises sealing means operable to seal the pump onto a body of a user.

16. A pump according to claim 15, wherein the sealing means comprises a sealing ring.

17. A pump according to claim 16, wherein the sealing ring is made from closed cell rubber sponge.

20. A method of causing or enhancing an erection of a human penis comprising inserting a generally flaccid penis into a chamber of a pump according to claim 1 and using pumping means to pump fluid from the chamber through the non-return valve.

18. A pump comprising a chamber adapted to receive a penis, a non-return valve, and pumping means operable to pump fluid from the chamber, wherein the pump further comprises rotatable volume adjusting means operable to adjust volume within the pump by rotation, and the rotatable volume adjusting means is operable to be adjustable between a plurality of discrete positions.

19. A pump comprising a chamber adapted to receive a penis, a non-return valve, and pumping means operable to pump fluid from the chamber, further comprising override means to allow a user to prevent fluid escaping from the chamber, by depressing an override button.
