Abstract

A device for use with condoms such as to prevent the leakage of semen from the forward part of the condom, along the inner surface of the condom wall and to the condom opening. The invention is characterized in that the device has the form of a ring (1) which is intended to be placed around the penis, immediately behind the glans penis; and in that the ring is provided with two beads (2, 3), preferably globular beads which are mutually spaced apart at a distance of 2 to 6 mm and each of which beads (2, 3) is intended to be placed on a respective side of the foreskin attachment on the underside of the penis.

Description

LEAKAGE PREVENTING DEVICE FOR USE WITH CONDOMS The present invention relates to a device which is intended for use with condone and which is either incorporated in the actual condom itself or is separate from and used together with a condom.

It has recently been established that sexiially-transmittible diseases are transmitted between sexual partners despite the fact that a condom is worn during intercourse and despite the fact that the condom is impervious to semen. This is borne out by the number of pregnancies that occur despite the fact that a condom had been worn at the time that intercourse took place. It has also been established recently that such occurrences are caused by the transportation of semen along the inner wall and out through the condom opening and, at times, onto the outer surface of the condom, during sexual intercourse. This problem is solved by the present invention. Accordingly, the present .Invention relates to a device for use with condoms which will prevent the leakage of semen from the forward part of the condom and along the inner surface of the condom wall to the condom opening, and is characterized by an elastic, stretchable ring which is intended to be placed around the penis, immediately behind the glans penis; and in that the ring is provided with two beads, preferably globular beads, which are spaced mutually apart at a distance of 2 to 6 mm, and each of which is intended to be positioned on a respective side of the foreskin attachment on the underside of the penis.

The invention will now be described in more detail with reference to an exemplifying embodiment thereof illustrated in the accompanying drawing, in which

- Figure 1 is a perspective view of the inventive device; and

- Figure 2 illustrates schematically and in section the inventive device fanned integrally with a condom. Figure 1 illustrates in perspective a device for use with condoms so as to prevent the leakage of semen from the front part of the condom, along the inside of the condom wall, to the condom opening. According to the present invention, the inventive device is comprised of an elastic, stretchable ring 1 can be placed externally around a condom and the penis accommodated therein, immediately behind the glans penis. Die ring functions to clamp tightly around the neck of the glans penis and therewith prevent said leakage. In order to prevent leakage in the region of the foreskin attachment on the underside of the penis, the ring 1 is provided with two beads 2, 3, preferably globular beads, which are spaced apart at a distance of from 2 to 6 mm. Each of the beads 2, 3 is intended to be placed on a respective side of the foreskin attachment an the underside of the penis. The beads therewith fill the region on respective sides of the foreskin attachment, so as to prevent leakage at this location of the condom.

The ring has a round cross-section with a diameter of about 1 to

2 mm. When the ring is not subjected to load, it will have a diameter of about 15 to 25 mm. In all events, the ring will have a diameter which is smaller than the diameter of the condom. The beads will suitably have a diameter of 2 to 5 mm, preferably 4 ran. According to one preferred embodiment, the cross-section of that part 4 of the ring located between the globular beads 2, 3 is larger than the cross-section of the remainder of the ring. This part, or section, 4 of the ring is preferably flat and has a width of from 3 to 5 ran and a thickness of about 0.5 to 1 mm. This flat part of the ring is intended to lie against the foreskin attachment.

The ring is made of silicone rubber or some corresponding material.

The ring is preferably extruded from liquid silicone rubber. The inventive ring may either have the form of a separate device intended for use together with a conventional condom or penile sheath, or may be made an integral part of a condom, which is conventional in other respects. Figure 2 is a schematic cross-sectional view of one of the beads included in the inventive ring when said ring is an integral part of a condom. The condom wall is referenced 5. The section is thus a part of an axial section of the condom. The ring 1 is seen at the lower edge. In the case of this embodiment, the inventive ring may first be produced separately and then made integral with a condom during the process of its manufacture, by dipping in latex. This can be effected by first building-up the condom to a given wall thickness, during its manufacture, and then placing the inventive ring in position and then dipping the condom into latex until the final wall thickness is reached.

It is also conceivable to glue the inventive ring to the outer surface of a manufactured condom.

In addition to solving the leakage problem mentioned above, the inventive ring will not result in constriction of the urethra, due to the positioning of the ring.

It will be understood that the present invention is not restricted to the aforedescribed exemplifying embodiments thereof, and that modifications can be made within the scope of the following Claims.

Claims

1. A device for use with condoms such as to prevent the leakage of semen from the forward part of the condom, along the inner surface of the condom wall and to the condom opening, characteri zed in that the device comprises an elastic and stretchable ring (1) which is intended to be placed around the penis, immediately behind the glans penis; and in that the ring is provided with two beads (2, 3) , preferably globular beads which are mutually spaced apart at a distance of 2 to 6 mm and each of which beads (2, 3) is intended to be placed on a respective side of the foreskin attachment on the underside of the penis.

2. An improvement according to Claim 1, characterized in that the ring (1) has a round cross-section with a diameter of about 1 to 2 mm.
