Abstract

To simplify and increase the efficacy of tubular vacuum chamber (6) used to induce and maintain erections in impotent men, a penile sealing diaphragm (7) forms an airtight seal between the tubular chamber (6) and the penis (28). A constriction band dislodging mechanism comprising a flexible strap (36) which is attached to the sealing diaphragm (7) provides a simple method for transferring any constriction band (8) from the chamber (6) onto the penis (28). A constriction band dislodging-vacuum release mechanism is used to simultaneously dislodge a constriction band (8) and relieve the vacuum within a chamber with an air hole (38). A unique constriction band (44) is formed from an inexpensive rubber band and two strips of glass tape which is easy to dislodge from the vacuum chamber (8) and easy to remove from the penis (28).

6. The device recited in claim 5 wherein said two strips of inelastic material are formed from two strips of glass tape, each of which is approximately 7.5 cm long and 1.25 cm wide.

7. The device recited in claim 1 wherein said elastic band dislodging means is formed from a piece of flexible flat material.

8. The device recited in claim 7 wherein said piece of flexible flat material is formed from a piece of latex rubber approximately 1.5 to 3.0 cm wide, 4.0 to 6.0 cm long, and 0.2 cm thick.

9. The device recited in claim 1 wherein said chamber and said elastic band dislodging means have air holes, said air holes being covered by an air hole sealing plug which has been attached to the undersurface of said elastic band dislodging means.

10. A device for inducing and sustaining an erection of a penis, comprising:

a) an elongated tubular penile vacuum chamber with a closed end and an open end receptive of said penis, said open end of said chamber being smooth and free of any obstructions which will impede the transfer of an elastic band from over said chamber onto said penis,

b) means connected to said closed end of said penile vacuum chamber for removing air from said chamber to induce blood flow to said penis so as to cause said erection,

c) elastic tube means for achieving an airtight seal between said open end of said penile vacuum chamber and said penis,

d) elastic band means for constricting blood flow from said penis, said elastic band means being positioned over said penile vacuum chamber, and

e) elastic band dislodging means for transferring said elastic band from said penile vacuum chamber onto said penis, said dislodging means comprising a member which has been attached to said elastic tube means.

11. The device recited in claim 10 wherein said elastic tube means comprises a segment of elastic tube, about 2.5 cm of one end of said tube being stretched to cover about 2 to 3 cm of said chamber'"'"'s distal wall, the other end of said elastic tube forming an elastic sleeve which will achieve said airtight seal with said penises of varying girth.

12. The device recited in claim 11 wherein said segment of elastic tube is approximately 7.5 cm in length, 2.5 cm in diameter, and has a wall thickness of about 0.1 cm.

13. The device recited in claim 10 wherein said elastic band dislodging means is formed from a piece of flexible flat material.

14. The device recited in claim 13 wherein said piece of flexible flat material is formed from a segment of latex rubber approximately 1.5 to 3.0 cm wide, 4.0 to 6.0 cm long, and about 0.15 cm thick.

15. The device recited in claim 10 wherein said elastic band means is manufactured from a rubber band and two strips of inelastic material.

16. The device recited in claim 15 wherein said rubber band is approximately 12 to 16 cm in length, 1.0 to 2.0 cm in width, and has a wall thickness of about 0.1 to 0.2 cm.

17. The device recited in claim 15 wherein said two strips of inelastic material divide said rubber band into three segments, namely, a central segment and two lateral segments, the distance between said strips determining the tension said central segment applies to said penis, said lateral segments forming finger loops which facilitate removal of said band from said penis.

18. The device recited in claim 10 wherein said vacuum chamber and said elastic tube means have air holes, said air holes being covered by said elastic band dislodging means.
