Abstract
Abstract Apparatus for obtaining an artificial erection by inducing flow of blood into the penis to stiffen it and applying a restrictor to its base to maintain the blood therein. A barrel chamber for the penis has a restricted tubular entrance and means for creating a vacuum in the chamber to which the penis is subjected to induce flow of blood thereinto. A resilient restrictor mounted on the entrance tube is shiftable therefrom to the base of the penis after erection to maintain the blood therein. The chamber has means for releasing the vacuum after which it may be withdrawn from the erected penis which may thereafter be used in normal copulation.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
119 words
Apparatus for inducing an artificial erection in a human penis comprising: means providing a chamber for the reception of the penis; an inelastic entrance tube to said chamber through which the penis extends, the internal diameter of said tube being larger than the relaxed diameter and smaller than the enlarged diameter of said penis, the interior surface of the inner end of said tube having a substantially frusto-conical form; means for evacuating said chamber to establish a vacuum about the penis to induce flow of blood thereinto and thereby increase the size and stiffness thereof; and means for releasing said vacuum by admitting air into the chamber to facilitate removal of the barrel body and tube from said penis.
Claim 2
Dependent Claim
119 words
Apparatus for inducing an artificial erection in a human penis comprising: means providing a chamber for the reception of the penis; an inelastic entrance tube to said chamber through which the penis extends, the internal diameter of said tube being larger than the relaxed diameter and smaller than the enlarged diameter of said penis, the interior surface of the inner end of said tube having a substantially frusto-conical form; means for evacuating said chamber to establish a vacuum about the penis to induce flow of blood thereinto and thereby increase the size and stiffness thereof; and means for releasing said vacuum by admitting air into the chamber to facilitate removal of the barrel body and tube from said penis.
Claim 3
Dependent Claim
24 words
The device defined in claim 1 in which the interior surface of the outer end of said entrance tube has a substantially frusto-conical form.
Claim 4
Dependent Claim
32 words
The device defined in claim 2 in which the frusto-conical interior surface of the outer end of said entrance tube is at an angle in the order of 6* to the axis.
Claim 5
Dependent Claim
31 words
The device defined in claim 1 in which the frusto-conical interior surface of the inner end of said entrance is at an angle on the order of 6* to the axis.
Claim 6
Dependent Claim
33 words
The device defined in claim 1 in which the interior surface of the frusto-conical inner end of said entrance tube is at an angle of between approximately 5* and 7* to the axis.
Claim 7
Dependent Claim
33 words
The device defined in claim 2 in which the interior surface of the frusto-conical outer end of said entrance tube is at an angle of between approximately 5* and 7* to the axis.
Claim 8
Dependent Claim
34 words
The device defined in claim 2 in which the interior surfaces of the frusto-conical inner and outer ends of said entrance tube are at angles of between approximately 5* and 7* to the axis.
Claim 9
Dependent Claim
38 words
The device defined in claim 1, and including in combination: an elastic restrictor mounted on the exterior surface of said entrance tube to be slid onto the base of the penis to prevent return flow of blood therefrom.
Claim 10
Dependent Claim
26 words
The device defined in claim 8, in which the relaxed diameter of said restrictor is substantially less than the diameter of the base of the penis.
Claim 11
Dependent Claim
18 words
The device defined in claim 1 including a vacuum pump mounted on said chamber to evacuate said chamber.
Claim 12
Dependent Claim
22 words
The device defined in claim 1 including means for detachably mounting said entrance tube to said chamber means in sealing relation thereto.
Claim 13
Dependent Claim
111 words
In an apparatus for inducing an artificial erection in a human penis, said apparatus including means providing a chamber for the reception of the penis, means for evacuating said chamber, and means for operatively associating an entrance tube with said chamber, the improvement which comprises: an entrance tube adapted to be operatively associated with said chamber for introducing the penis into said chamber, said tube being inelastic and having an internal diameter larger than the relaxed diameter and smaller than the enlarged diameter of said penis; the inner end of said tube leading into said chamber having a substantially frusto-conical form to facilitate removal of said tube from the enlarged penis.
Claim 14
Dependent Claim
111 words
In an apparatus for inducing an artificial erection in a human penis, said apparatus including means providing a chamber for the reception of the penis, means for evacuating said chamber, and means for operatively associating an entrance tube with said chamber, the improvement which comprises: an entrance tube adapted to be operatively associated with said chamber for introducing the penis into said chamber, said tube being inelastic and having an internal diameter larger than the relaxed diameter and smaller than the enlarged diameter of said penis; the inner end of said tube leading into said chamber having a substantially frusto-conical form to facilitate removal of said tube from the enlarged penis.
Claim 15
Dependent Claim
24 words
The device defined in claim 12 in which the interior surface of the outer end of said entrance tube has a substantially frusto-conical form.
Claim 16
Dependent Claim
32 words
The device defined in claim 13 in which the frusto-conical interior surface of the outer end of said entrance tube is at an angle in the order of 6* to the axis.
Claim 17
Dependent Claim
31 words
The device defined in claim 12 in which the frusto-conical interior surface of the inner end of said entrance is at an angle in the order of 6* to the axis.

Dependent Claim
33 words
The device defined in claim 12 in which the interior surface of the Frusto-conical inner end of said entrance tube is at an angle of between approximately 5* and 7* to the axis.
Claim 19
Dependent Claim
33 words
The device defined in claim 13 in which the interior surface of the frusto-conical outer end of said entrance tube is at an angle of between approximately 5* and 7* to the axis.
Claim 20
Dependent Claim
34 words
The device defined in claim 13 in which the interior surfaces of the frusto-conical inner and outer ends of said entrance tube are at angles of between approximately 5* and 7* to the axis.
Claim 21
Dependent Claim
38 words
The device defined in claim 12 and including in combination: an elastic restrictor mounted on the exterior surface of said entrance tube to be slid onto the base of the penis to prevent return flow of blood therefrom.
Claim 22
Dependent Claim
