Description

BACKGROUND OF INVENTION

1. Field to which Invention Relates

The present invention relates to devices for facilitating sexual intercourse contraceptives, and more particularly to contraceptives in the form of a substantially cylindrical comparatively thick-walled hollow body of elastic material, whose one end is open and whose other end merges with a rounded part.

2. The Prior Art

As is known, contraceptives serve two chief purposes. On the one hand they should ensure that conception should not occur; furthermore they should cut out infection with venereal disease. Besides these two main requirements, which should be fulfilled by practically every contraceptive, there are still further requirements regarding contraceptives. These further requirements can be classified in accordance with two different points of view. In the case of one type of contraceptive there is the requirement that the pleasure of the male partner should not be impaired by the use of the contraceptive. On the other hand with the other type of contraceptives there is the intention to construct the contraceptive so that the stimulation of the female partner is enhanced in order in this manner to balance out the different degree of sexual excitability of the two partners. Furthermore a distinction is drawn between contraceptives which are only intended for use once and contraceptives which are intended for use repeatedly.

The present invention is concerned with contraceptives for repeated use which are more particularly intended to compensate for an insufficient adaptation of the development of the organs or organ conditions in the two partners and even in the case of unfavorable conditions ensure that the female partner is completely satisfied.

The invention is based on prior art relating to contraceptives with comparatively thick walls and of stiff construction in order in this manner to overcome insufficient adaptation as regards the size of the organs of the two partners and/or of the sexual excitability of the partners, and possibly also overcome a lack of potence in the male partner.

The main disadvantage of these known contraceptives is to be found in that the substantial strength or rigidity of the materials used may easily create an unnatural effect so that such contraceptives distract the two partners and there is also the disadvantage that owing to the strength of rigidity of the material, more particularly after a long period of use, the material may become brittle so that it may readily be damaged with the result that the contraceptive is in fact not likely to be so suitable for repeated use as was intended.

Furthermore in the case of known contraceptives of a high degree of rigidity, there is the problem that they have a very limited interior space which makes the insertion of the male organ difficult and in some cases even painful. Alternatively if the interior space or its entry opening is made large in order to avoid this difficulty there is likely to be the inconvenience that, if the male organ becomes less turgid, the male contraceptive slides off so that the contraceptive cannot properly fulfill its function of ensuring that conception cannot take place and that the chance of infection is also cut out reliably. Furthermore there may be difficulties owing to the fact that such a contraceptive when it has once slid off the male organ cannot be withdrawn from the female partner, more especially owing to the suction effects occurring with very thick contraceptives.

SUMMARY OF INVENTION

One aim of the present invention is that of providing a contraceptive which is completely satisfactory both as regards its purpose of ensuring that conception and infection do not occur, while on the other hand owing to a suitable choice of material does not cause any distraction of the partners. A further object of the invention is to provide such a contraceptive which is capable of overcoming an insufficient capability of erection of the male organ after some time, or at least improving the erectability of the male organ.

In accordance with the invention a contraceptive is provided of the above-described type which is characterized in that the elastic material is very soft and yielding and in that the interior space of the hollow body is connected with the outside both via the open end and at least one valve, the valve being adapted to open when there is an excess pressure in the hollow body and to close when there is a lesser pressure inside than outside.

It has been found advantageous if the hollow body is provided at its open end with a bead or ridge or the like, which ensures that the contraceptive does not penetrate excessively far into the vagina, the bead or ridge being provided with a means for excitation of the clitoris. In this respect the means for exciting the clitoris can in accordance with an advantageous form of the invention be constructed substantially in the form of a brush or can on its surface have plate-like projections. The means for excitation of the clitoris can in accordance with an advantageous form of the invention be connected detachably with the bead. In order to facilitate placing the contraceptive in accordance with the invention on the organ, it has also been found advantageous if the interior space of the hollow body has a conically tapered part opening towards the open end, to which it is adjacent, while behind this part of restricted cross-section the inner space of the hollow body again corresponds in diameter to the open end.

DESCRIPTION OF PREFERRED EMBODIMENTS

The embodiment shown in FIG. 1 of a contraceptive in accordance with the invention is denoted by general reference numeral 1. The contraceptive is constructed as a comparatively thick-walled hollow body and made of a material which in comparison with materials which were previously used for such thick walled contraceptives, are very soft and yielding. The open end of the interior space of the hollow body firstly tapers conically as far as a restricted portion, which is formed by a surrounding collar 2. Behind the collar 2 and towards the interior space the diameter of the hollow space again increases but advantageously remains initially of a lesser diameter than the front part of the interior space, for reasons which will be explained later. At a position adjacent to the closed end of the contraceptive in accordance with the invention as shown in FIG. 1a duct 4 begins, which passes through the material of the hollow body and ends in a valve 3. This duct and the valve at its end has the purpose of reducing pressure which is built up when the male organ is introduced into the contraceptive. The valve also hinders any return flow of air when a subatmospheric pressure arises in the interior space of the hollow body in order to ensure that the contraceptive remains well fixed even when externally acting suction forces act upon it. In regard to this point it is pointed out that the valve can naturally be arranged at very different positions in which it can be effective. It may be possible for instance to provide a valve directly on the wall of the hollow body so that it is not necessary to use a separate duct.

By the combination of the described features used in the contraceptive in accordance with the invention a highly desirable physiological effect occurs. Owing to the narrow collar 2 at the open end of the contraceptive there is not only a reliable exclusion of air, but also a certain compressing action or damming action is attained which to a certain extent hinders the return of blood pumped into the corpora cavernosa of the male organ and thus ensures that there is no premature loss of turgidity of the male organ. This effect is furthermore reinforced by the fact that the part of smaller diameter lying towards the closed end of the interior space also lies closely against the organ. Furthermore owing to movements during intercourse and owing to the arrangement of the duct 4 and the valve 3 in accordance with the invention in the interior of the hollow body a reduced pressure or suction effect of varying intensity is produced which on the one hand brings about better blood circulation in the organ and on the other hand therefore also works to achieve the desired effect.

It is obvious that in the case of use of the contraceptive in accordance with the invention over a long period of time owing to the suction effect produced in it and the massage properties, which can be enhanced by the arrangement of plate-like projections 7 in the front part of the interior space of the contraceptive, improved blood circulation of the organ is achieved so that the organ is more vigorous. As a result if the contraceptive was only necessary for compensating for a lack of potence it is possible after some time to dispense with the use of this aid.

In order to achieve a more pronounced stimulation of the clitoris, it is furthermore possible to broaden out the bead 9 of the contraceptive in accordance with the invention in the relevant zone and construct it in such a manner that the aim desired is achieved. In this respect it has been found particularly favorable if this zone is in the form of a brush, which can, for example, be embodied as soft rubber projections. It is, however, possible to use means whose surface is provided with plate-like projections. In particular in the case of the construction of the contraceptive in accordance with the invention it is also possible to produce the means for stimulating the clitoris separately and only to place it on the bead 9 when this is desired.

In order to counteract the creation of an excessively high degree of suction in the interior of the hollow body, it is possibly in accordance with an advantageous embodiment of the invention to provide the contraceptive with a second valve 5 and a duct 6 leading from this valve to the interior of the hollow body. In this case the valve is so constructed that it opens as soon as the suction or reduced pressure in the interior space of the hollow body exceeds a certain pre-established value. It is furthermore possible to provide the contraceptive in accordance with the invention with a bead-like projection 8 extending substantially in the peripheral direction at a position adjacent to the closed end on the outside. This projection 8 may be provided in the form of material which has a higher strength or rigidity than the rest of the material of the contraceptive. On the one hand this bead makes the contraceptive look more natural and on the other hand stimulates the female partner owing to the more natural features. The same effect is also achieved by a further contraceptive in accordance with the invention, which is not specially shown in a drawing and whose surface is made corrugated by grooves extending at least partially in the peripheral direction.

A further preferred embodiment of the invention is shown in FIG. 2. This embodiment, which otherwise has the same features as that described in the FIG. 1, is also provided additionally with a tube-like casing 10, which surrounds the substantially cylindrical part of the hollow body externally and whose ends are connected along a peripheral line 11 and along a narrower or broader strip rigidly with the cylindrical part. The length of the tube-like casing 10 is in this respect selected so as to be greater than the distance between the peripheral lines 11, at which the ends of the casing are attached. If the intermediate space between the cylindrical hollow body and the hose or tube-like part is filled before sealing with a lubricating powder, a liquid, or a mixture of these, the casing 10 can be moved between its two end positions, of which the upper one is shown in full lines while the lower position is shown in broken lines. With the help of such a contraceptive the stimulation of the female partner is decreased to the natural level, so that more particularly in the case of a very sensitive female partner the male partner does not need to discard medical means which may have been necessary.

A further embodiment of the invention, which is designed for a particular purpose is shown in FIG. 3. The embodiment shown in this figure of the drawings has at the front end of the hollow body an extension whose front part is constructed for receiving the cervix. This contraceptive serves, in contrast to the above-mentioned embodiments, not for ensuring that conception does not take place, but on the contrary for enhancing the chances of conception. As can be seen from FIG. 3, the front end of the interior space of the hollow body is connected via a duct 12 with the groove or recess 13 for receiving the cervix. In the duct a valve 14 is arranged which opens when there is an excess pressure inside the hollow body. In other respects the contraceptive has substantially the same features as shown in FIG. 1. Owing to the overall length of the contraceptive achieved by this lengthened construction it is possible for the groove 13 or recess to lie directly against the cervix. When ejaculation occurs, the valve 14 opens owing to the excess pressure built up and the sperm is thrown directly against the cervix. In this manner the chances for conception are increased, more especially in the case of men who owing to age or processes of disease only produce a few sperm cells or whose sperm is weak. These sperm cells are led directly to the cervix with the help of this contraceptive in accordance with the invention so that favorable conditions for conception are achieved. Naturally in order to achieve the effect desired care should be taken that the organ lies as closely as possible to the distal end of the interior space when ejaculation occurs. The organ should also be close to the duct 12 in order that there is sufficient excess pressure in order to open the valve 13 reliably.

FIGS. 4a and 4b show a cross-section and plan view of a valve for a contraceptive in accordance with the invention. As is shown in FIG. 4a the valve body 15 which is also made of elastic material is made up by two frusto-cones, which have their apices joined together. As a result when the valve is inserted into a suitably shaped recess in the wall of the hollow body 1 there is a dovetail joint which holds the valve reliably. Within the valve body 15 there is a comparatively narrow hole 16, which widens conically in the valve body and merges with a large hole 17. The direction in which the air flows through the valve is indicated by an arrow. It can be seen that the hole 16 of smaller diameter first passes entering fluid to a membrane 18, which is held on its upper surface by a valve cone 19, which in turn is connected with a cross-like holding means 20, as is shown in FIG. 4a. The holding means 20 is fixed on the valve body 15. As soon as the pressure on the inlet side reaches a pre-established value, which can be determined by the selection of the membrane material, the membrane comes clear of the conical face, which it lies against when the valve is closed, and allows air to emerge. The simple construction described and the material used in accordance with the invention make the valve shown in FIGS. 4a and 4b especially suitable for the purpose in hand, since owing to the simple construction there is a long service life and satisfactory operation. Since the material selected, in contrast to metal for instance, cannot oxidize or rust it is particularly suitable for the purpose in view.

A material which can be used for the hollow body 1 has been found to be silicone rubber and plastic-silicone rubber.
