Intraurethral contraceptive device

The invention relates to medicine, especially to intraurethral contraceptive devices, used by men.

In unwarranted modem contraception with little attention is paid to preserving the partners' natural intimacy during sexual intercourse, often the natural nature of intimacy is sacrificed in favor of the efficiency of solutions to certain contraception problems, regardless of the secondary consequences.

One of the most common methods is hormonal contraception (hormonal contraceptive pills, implants and injections). The disadvantage of this method of contraception is the serious interference in the nature of the body and, consequently, a high incidence of adverse side effects, such as the increased risk of developing breast cancer or vascular disorders with a probability of thrombus formation. There is also a high probability of depression and decreased libido.

A widely used means of contraception is also the condom, the serious disadvantage of which is the perceptible obstacle in the intimacy, sensitivity, intensity of sexual sensations during sexual intercourse, due to the physical barrier, which leads to decreased sexual satisfaction. and it requires some time and dexterity in the erection on the erect genital body immediately prior to intercourse and is also a disadvantage.

As the closest solution, a contraceptive device is used, which confines an elastically sealed elongated chamber with an enclosed end, with the other having an о valve. The known device fits completely into the urethra, with the end closed inside, and the other end with valve at the end of the glans penis, after which the device is swollen to ensure complete contact with the urethra, to exclude the fall of the urethra chamber during intercourse and after ejaculate [1].

An essential disadvantage of the known device is the prevention of the natural ejaculation of the ejaculate, organized by the rhythmic contraction of the prostate, the muscles of the perineum and of the sexual organ itself, where together with the swollen chamber, which tightly presses on the wall of the urethra, it is created to block it. о region of extreme pressure, which can cause serious discomfort, tension or even deterioration of the urethra. Also, in relation to the high and increasing pressure of the ejaculate, as the repeated contraction of the muscles is high, the probability of the last one breaking the barrier of the device installed in the urethra in the female genital organs is high.

The problem that the present invention solves is the ease of use of the device, the assurance of natural genital contact, as well as the effective prevention of unwanted pregnancy.

The problem is solved by the fact that the intraurethral contraceptive device confines an inflatable chamber of a toroidal shape, covered with a covering with the possibility of its elimination. In the inner wall of the room is executed at least one pierced channel for cutting the gas environment. The inner wall is executed in a cylindrical form with the formation of a pierced channel, at an opening whose entire circumference is hermetically fixed with its open part an elastic receiver, located entirely in the pierced channel. At the same time, in the middle portion of the inner wall, from two opposite sides, weak V-shaped sections are executed, joined to each other by means of a wire, located in the pierced channel.

The camera can be inflated, with the possibility of attaching it to the user's nav.

The intraurethral contraceptive device is located in the urethra, in the extension of the penile gland, called - navicular fossa.

The technical result of the claimed invention consists in the ease of use of the device, the assurance of 100% absolute natural genital contact during intercourse, the effective prevention of unwanted pregnancy.

The toroidal-shaped swollen chamber serves as a means of fixing the device entirely in the cavity of the navicular cavity on account of the tight contact of the chambers of the chambers with the mucous membranes of the urethra, organized by the pressure of the precalculated volume of the gas environment introduced into the chamber by the at least one passing channel. through its wall. As a gaseous environment, in particular, it can serve the air.

The inner wall of the chamber is executed in a cylindrical form with the formation of a perforated channel, which is located m in relation to the urethra in parallel and serves to eliminate or redirect the ejaculate flow from the urethra into the cavity of the elastic receiver, hermetically fixed with its open part at the hole in the canal. all the circumference.

Under the action of the pressure of the ejaculatory flow, the receiver opens outside the urethra, receiving in itself all the ejaculatory products, without creating perceptible resistance to flow, which is freely eliminated without creating direct pressure on the swollen chamber, which secures the device to the user's nav record.

As a means of detaching the chamber and extracting the intraurethral contraceptive device, the weakened V-shaped sections (partial cuts), executed in the middle portion of the inner wall, from two opposite sides, which are joined to each other by a wire, located in the pierced channel. The place of the cut represents a minimum thickness of the wall of the chamber necessary to maintain its tightness in a swollen state, as well as for easy breaking through the tensile force applied to the thin resistant wire. The thin wire (in the simplest case, of the nation) has a slightly larger length compared to the length of the open receiver and is folded together with it in the channel cavity.

The invention is explained by the drawings in figures 1-3, which represent:

FIG. 1, the device, view m section with the inflated chamber and the receiver folded;

FIG. 2, the device, sectional view with the chamber inflated and the receiver folded;

FIG. 3, the device, overview with the receiver installed open.

The intraurethral contraceptive device contains о 1 toroidal-shaped inflatable chamber, a channel 2 pierced through the gas flow, a wall 3 inside the chamber 1, a channel 4 pierced, an elastic receiver 5, a thin 6 wire, 7 weakly shaped sections. from V.

The intraurethral contraceptive device is used in the following way: it is inserted into the urethra with the open end of the receiver inside the penis using a simple device, which allows the introduction of the device with chamber 1 inflated preliminary as follows: the device is completely placed in a rigid shell with thin walls (m the simplest case of cellophane) of cylindrical shape, which has the same diameter as the device in an inflated state, with one closed end and with the other end fixed by о flange throughout the perimeter section. At the closed end of the shell is made a small cut with durable thin strips fastened by it (in the simplest case of cellophane), which tree through the holes made in the walls of the flange and form a loop over it. In room 1 through channel (slabs) 2, enter the preset volume of gaseous environment (in the simplest case of air), after which channel (slabs) 2 is blocked or sealed (in the simplest case with an adhesive-melt or with a stopper). At the same time, the casing does not allow the volume increase of the device, the gas environment in the room being in compressed state.

The chamber 1 swollen in the casing is inserted into the urethra hole so that the flange comes in tight contact with the glans penis. In this position, with one hand holding the glans penis and the flange with another hand, resting the thumb on the flange, the forefinger gently pulls the loop, formed by the thin strips of the cellophane fixed by the cut on the closed end of the shell, thus breaking it , then pull the cover, holding the flange, beyond the limits of the urethra. The volume of the room 1 is increased under the action of the pressure of the compressed gas environment, by this the device is securely fixed entirely in the user's naval fossa.

The elastic receiver 5 folded under the action of the flow pressure directed by the ejaculate opens beyond the limits of the urethra together with the resistant thin thread 6 (in the simplest case of the nation), receiving in itself all the ejaculate products, without creating о perceptible resistance to the flow, which is freely removed without creating direct pressure on the inflated chamber 1, which secures the device to the user's navicular. Then the wire 6, fixed with one end of the first and the other end of the second section 7 weakened in the form of V, is pulled by breaking the thin wall 3 of the inner lateral surface of the chamber, as a result of the toroidal chamber 1 being dislodged.

The claimed device solves the problem of maintaining the sexual intimacy of the sexual partners together with the high efficiency of protection against unwanted pregnancy, without causing side effects, which is the guarantee of harmony in the sexual relations of the man and the woman.
