Abstract
Abstract A device for aiding men to attain and maintain erection consisting of an inflatable ring adapted to be inserted around the base of the penis and then inflated so as to apply a radially inward force thereto sufficient to retain blood in the organ; and a tubular sleeve portion with a bulb integrally formed thereon, that can be inserted over the penis and secured about the ring element in sealing engagement therewith, whereupon the bulb can be actuated to develop a low pressure within the interior of the tube and outside the penis, to aid in causing an erection, the ring retaining the blood to maintain the erection, the tubular part then being removable to permit copulation. After copulation, the ring can be deflated and removed. The ring can also be used in preventing urinary incontinence in males.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
In a device of the kind described: a toroidal ring member of flexible and inflatable material; filling means by which an inflating fluid under pressure may be introduced into the interior of the toroidal member and including means to prevent egress of fluid therefrom, the last two means comprising a valved passage through the wall of the ring member and a valve in the passage, the valve being inward of the outer surface of the ring member so as to afford minimal extension of the valve beyond the outer surface of the ring member, the ring member having an inner diameter when uninflated approximately equal to the size of a penis, and being inflatable to reduce the inner diameter to produce a pressure on a penis that can restrain outflow of fluid therefrom.
Claim 2
Dependent Claim
133 words

Claim 3
Dependent Claim
55 words
The device of claim 1 together with a tubular sleeve adapted to be fitted over a penis and extend beyond the end thereof, means to engage the tubular member with the toroidal member, said means being releasable to permit the tubular member to be inserted or withdrawn, and means to reduce pressure within the sleeve.
Claim 4
Dependent Claim
25 words
The device of claim 2 wherein the means to reduce pressure comprises a bulb portion integrally formed with the sleeve and formed of flexible material.
Claim 5
Dependent Claim
34 words
The device of claim 2 wherein the means to reduce pressure comprises a bulb on the sleeve and a check valve to permit expulsion of air from the sleeve but to prevent inflow thereof.
Claim 6
Dependent Claim
49 words
The device of claim 2 wherein the ring is made of flexible plastic, the sleeve is made of a relatively stiff plastic, and the bulb is made of a plastic that can be compressed and yet which will return to original shape to produce the low pressure within it.
Claim 7
Dependent Claim
28 words
The device of claim 1 wherein the toroidal member has a means to restrict its expansion outwardly, so as to insure the expansion inwardly when it is inflated.
