US 5,683,383 A · Internal ring release erection device

Abstract

An expanded elastic ring is supported in an annular groove within a ring outer cylinder for use in vacuum therapy of a dysfunctional penis. The cylinder has an open end for initial placement against a user's body with the penis contained within the cylinder. The cylinder further comprises a cap on a closed end into which a vacuum pump is integrated. The elastic ring expanded around an inner cylinder into an annular groove is remotely released within a vacuum drawn within the cylinder. In a first embodiment, the vacuum effects the release as the inner cylinder is withdrawn into an outer cylinder until the ring falls off of the inner cylinder end. In a second embodiment, push rods extending into the annular groove push the ring past a stationary inner cylinder, effected by rotation of the cap on the cylinder. An inclined face on the cap bottom surface engages the rod, pushing the rod into the annular groove.

Dependent claims

An internal ring release erection device comprising

a hollow outer cylinder having a side wall, a closed end, and an open end adapted to achieve a temporary seal against a user's body,
a ring support ledge integral with and internal the side wall near the open end but spaced apart a distance therefrom,
a releasable ring,
an inner cylinder at the ring support ledge internal to and concentric with the outer cylinder terminating in first and second ends with the first end extending past the ring support ledge toward the outer cylinder open end forming an annular groove with a base in the ring support ledge, the elastic ring received therein expanded around the inner cylinder,
means for reducing air pressure within the outer cylinder when its open end achieves a temporary seal against a user's body,
means for releasing the elastic ring from the annular groove internal the outer cylinder while said outer cylinder open end maintains said temporary seal against said user's body with reduced air pressure within the outer cylinder comprising means for moving the elastic ring longitudinally relative to the inner cylinder which includes
a. an inner cylinder affixed within the ring support ledge, and
b. means for urging the elastic ring out of the annular groove past the inner cylinder first end, causing the ring to release over the inner cylinder, including
i. one or more push rods each with a head on a rim end,
ii. the ledge with one or more ledge bores and one or more push rods slideably passing through one or more ledge bores terminating with a push rod groove end at the groove base,
iii. means for remotely pushing said one or more push rods into the annular groove against the elastic ring.

The device of claim 4 in which the means for remotely pushing said one or more push rods into the annular groove comprises

an inward-extending circumferential rim having one or more holes therethrough in alignment with said one or more ledge bores in the support ledge integral with and internal said outer cylinder side wall near the closed end but spaced apart a distance therefrom,
said push rod having a length such that in a first, or rest, position it extends in said rest position beyond the rim toward the outer cylinder closed end,
a stop intermediate the push rod length,
a coil spring through which the push rod passes between the stop and the ledge to support the push rod in said rest position such that when the rod is pushed downward against the spring the rod enters the annular groove, pushing the ring out of the groove, and when the rod is released, the spring returns it to its rest position,
a rotatable cap,
means to secure the cap to the outer cylinder closing the outer cylinder closed end,
means on the rotatable cap for remotely pushing the push rod into the annular groove.

The method of causing a penile erection of a dysfunctional penis through vacuum therapy using an elastic ring to constrain blood artificially drawn into the penis using an outer cylinder having a closed end and an open end adapted to achieve a temporary seal against a user's body, and an elastic ring supported in an annular groove defined between an inner cylinder and the outer cylinder, said ring releasable within the outer cylinder around the penis while a vacuum is maintained in the outer cylinder and before the outer cylinder is separated from a user's body, the method comprising the following steps:

a. Installing an expanded elastic ring internal to the outer cylinder in the annular groove by
i. Using an outer cylinder comprising a tube section removably engaged on the outer cylinder open end sized to fit snugly thereon and comprising therein an outer side of the groove, removing the tube section from the outer cylinder wall, the groove presenting therein a cylindrical shelf;
ii. Placing an elastic ring on the shelf, expanded around the cylindrical shelf;
iii. Replacing the tube section over the outer cylinder wall, thereby establishing the elastic ring in the annular groove internal the outer cylinder.
b. Inserting the penis into the open end of the inner cylinder;
c. Holding the outer cylinder open end tightly against the user's body to achieve a temporary seal;
d. Reducing air pressure within the outer cylinder until a penal erection is achieved;
e. While maintaining reduced air pressure, remotely releasing the elastic ring from the inner cylinder into the outer cylinder near its open end with the ring constricting around the penis;
f. Separating the outer cylinder from the user's body and penis.
