Device to induce increased intrauterine pressure

Technical field

The invention relates to a device for producing increased intrauterine pressure, the purpose of which is to allow the uterus to be filled with a suitable physiological filling so that the pressure of the intrauterine filling can be easily controlled from the outside. The device is used for mechanical contraception and passive pressure expansion of smooth uterine muscles, which in turn causes their emptying contractions. Inducing emptying uterine muscle contractions is used to exercise strength and co-ordinate uterine contractions, particularly useful in women who have not yet given birth and want to prepare not only for their own pregnancy but also for childbirth, and also to facilitate the achievement of orgasm in a woman.

BACKGROUND OF THE INVENTION

Prior art mechanical contraceptives are used as barriers to preventing the penetration of semen from the vagina into the uterus, for example, a condom or pessary. In addition to a lower degree of contraceptive reliability, these agents may interfere with the actual sexual intercourse.

Although we know that both the birth and the female orgasm are emptive uterine contractions, there is still no tool to allow women to regularly train the coordination and strength of uterine contractions, which is crucial for healthy psychosexual maturation of adolescent girls and women, as well as for their proper preparation for truly natural, spontaneous and painless delivery.

The essence of the technical solution

The principle of the device for generating increased intrauterine pressure, which is intended to allow the walls of the intrauterine cavity to be expanded with a physiologically suitable filling so that the pressure of the intrauterine cavity can be easily controlled from the outside, consists of an intrauterine balloon equipped with a balloon tube emptying the balloon with liquid or gas.

The length of the balloon tubing is such that it protrudes from the vagina when the balloon is placed inside the uterus.

During this balloon tubing, valves are then provided to control the filling and emptying of the intrauterine balloon.

This control can be provided, for example, by providing at least one valve during the balloon tubing to prevent spontaneous leakage of the balloon from the balloon when it is filled from the outside, and at least one valve allowing the balloon to empty when a certain external pressure is exerted on the balloon walls.

The process of filling and emptying the intrauterine balloon can also be regulated by providing at least one valve inside the balloon tubing that fulfills both of the above functions,

I.e., it not only prevents the spontaneous leakage of the balloon from the balloon when it is filled from the outside, but also allows the balloon to be emptied when a certain external pressure is exerted on the walls of the intrauterine balloon.

For the purpose of introducing an intrauterine balloon into the uterus within the entire length of the balloon tube channel, the telescopic rod is retracted freely.

Until the moment of insertion of the intrauterine balloon into the uterine cavity, this tubular balloon is placed inside the guide tube, which together with the above-mentioned telescopic rod serves for the actual insertion of the intrauterine balloon into the uterus.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawing shows schematically an exemplary embodiment of an increased intrauterine pressure device according to the invention.

Examples of technical solution

The above-described device for inducing increased intrauterine pressure removes, inter alia, the aforementioned drawbacks of all prior art mechanical contraceptives. The intrauterine balloon 1 with tubing 2, namely due to its location in the uterus, can have no disruptive effect on the course of the coitus, but in its expanded state it prevents sperm from penetrating the vagina to the egg inside the fallopian tube, which should guarantee a significantly higher degree of functional reliability than other mechanical contraceptives.

Above all, the proposed technical solution eliminates the absence of a device that would enable women to systematically train the coordination and strength of emptying uterine muscle contractions. At the same time, the device takes advantage of the special physiological properties of the smooth muscle, in that the smooth muscle contractes spontaneously after previous stretching without any stimulating nerve impulses. As a result, by increasing the volume and pressure of the filling in the intrauterine balloon, a passive stretching of the uterine muscle fibers can be induced in the first phase, which in the second phase begins to contract themselves after reaching a certain degree of expansion.

In this way, it is possible to induce emptying uterine muscle contractions, which not only enables regular training of coordination and strength of uterine contraction, which is especially important for women who have not yet born and want to prepare for their own pregnancy and above all to ensure painless and spontaneous delivery , but it also enables a significant improvement in the course of sexual intercourse with a partner, as it is the feeling of filling the uterine cavity, which is an important stimulus for inducing orgasm in a woman.

The basis whose shape in the technical solution is an intrauterine balloon 1, in the filled state, at least approximately corresponds to the shape of the intrauterine cavity. This intrauterine balloon is provided with a tube 2 which allows it to be filled and emptied by liquid or gas. Due to its function, the balloon tube 2 must be long enough to protrude at least 15-20 cm from the vagina 5 while placing the uterine balloon 1 in the uterus 4, but at the same time sufficiently flexible and elastic to be rolled up. and insert it into the vagina 5 without obstructing or hindering sexual intercourse. ;

The tubing 2 serves to fill the intrauterine balloon 1 with a physiologically acceptable filling 6 with either liquid (e.g. sterile saline) or gas. In order to prevent spontaneous leakage of the cartridge 6 from the intrauterine balloon 1, the hose 2 may be provided with a valve 3 and valves 3a-3b, respectively. which prevents the spontaneous leakage of the cartridge 6 from the balloon 1 outward, but at the same time, upon reaching a certain preset externally exerting pressure on the walls of the balloon 1, allows the intrauterine balloon 1 to be emptied later during uterine muscle contractions. Said valve 3 or valves 3a-3b may be located anywhere during the balloon tube 2, but in order not to interfere with sexual intercourse, the position of valve 3 and valves 3a-3b, respectively, is most preferred. in that portion of the balloon tube 2 to be placed inside the uterus 4 when inserted.

The pressure of the cartridge 6 in the intrauterine balloon 1 can be gradually increased as needed until the smooth muscle fibers of the uterus 4 passively expand to such an extent that their spontaneous emptying contractions occur, causing the cartridge 6 to be expelled from the intrauterine balloon 1. The uterine balloon 1 is emptied again through the channel inside the tubing 2.

The intrauterine balloon 1 is inserted into the uterus 4 either by means of a rigid conductor 7 inserted inside the channel of the balloon tube 2, possibly also by means of a guide tube 8, inside which the intrauterine balloon 1 with tube 2 is placed before its actual introduction into the uterine cavity.

Technical use

The device designed to induce increased intrauterine pressure serves as a mechanical contraceptive, which in the expanded state fills the entire intrauterine cavity and thus effectively prevents the penetration of sperm on their way to the egg stored in the cavity of the fallopian tube, as an aid for regular training to better prepare for later painless and spontaneous emptying of the uterus 4 at delivery and also as a means of inducing emptying orgasmic uterine muscle contractions in a pregnant woman (female orgasm), which is essential not only to achieve sexual satisfaction of the woman but also to healthy psychosexual maturation of somatosexual teenage girls as well as somatosexual adult women.
