Abstract
Abstract A simple and inexpensive device for measuring radial expansion of tube-like structures which is particularly useful to measure male potency. A radially expansible loop comprising a flexible, relatively slippery tube made from a material such as paper or a thermoplastic film having an elongated tail of the same or different material extending therefrom is drawn tight around the flaccid penis, by means of draw means at the end of the tail, and held in place by an adhesive patch. Should an erection occur the tail slides partially out of the tube to accommodate the radial expansion which occurs and remains in the extended position until manually retracted by pulling the draw means at the end of the tail. The radial expansion can be assessed by measuring the extension of the tail exposed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
135 words
A device for monitoring penile expansion comprising: an elongated thin walled tubular member having first and second ends and made from a soft and flexible but inelastic material, and including hole means in the wall adjacent said first end thereof; a soft and flexible but inelastic tail member extending longitudinally from said first end of said tubular member and terminating with a draw pull means; said tail member being insertable axially into said tubular member at said second end with said draw pull means projecting outwardly through said hole means thereby arranging a substantial portion of said tail within said tubular member for sliding movement relative thereto so as to provide a closed loop which is freely radially expansible in response to erectile activity of a flaccid penis about which said loop is tightly drawn.
Claim 2
Independent Claim
135 words
A device for monitoring penile expansion comprising: an elongated thin walled tubular member having first and second ends and made from a soft and flexible but inelastic material, and including hole means in the wall adjacent said first end thereof; a soft and flexible but inelastic tail member extending longitudinally from said first end of said tubular member and terminating with a draw pull means; said tail member being insertable axially into said tubular member at said second end with said draw pull means projecting outwardly through said hole means thereby arranging a substantial portion of said tail within said tubular member for sliding movement relative thereto so as to provide a closed loop which is freely radially expansible in response to erectile activity of a flaccid penis about which said loop is tightly drawn.
Claim 3
Dependent Claim
23 words
A device as claimed in claim 1 including scale means on said tail member arranged to measure radial expansion of said closed loop.
Claim 4
Dependent Claim
35 words
A device as claimed in claim 1 including adhesive means on at least a portion of the inner periphery of said closed loop, to secure said loop in a selected longitudinal position on said penis.
Claim 5
Dependent Claim
25 words
A device as claimed in claim 1 wherein said draw pull means comprises a draw string secured to the terminal end of the tail member.
Claim 6
Dependent Claim
23 words
A device as claimed in claim 1 wherein said draw pull means comprises a tab at the terminal end of the tail member.
Claim 7
Dependent Claim
32 words
A device as claimed in claim 1 wherein said tubular member and said tail member are fabricated from materials selected from the group comprising paper, plastic coated paper and thermoplastic film material.
Claim 8
Dependent Claim
22 words
A device as claimed in claim 6 wherein said tubular member and said tail member are fabricated from different said selected materials.
Claim 9
Dependent Claim
28 words
A device as claimed in claim 6 or 7 wherein said tubular member and said tail member include means to provide one-way slip therebetween in the expansile direction.
