Description

The utility model relates to pessaries and can be used in the treatment of women suffering from prolapse and prolapse of the pelvic organs, prolapse of the uterus, and urinary incontinence.

In recent years, more and more women are turning to doctors about a rather serious disease - omission and prolapse of the pelvic organs. Often, pelvic prolapse is accompanied by urinary incontinence with tension, sneezing, coughing and weight lifting, i.e. stressful type. The prolapse of the genitals in the early stages is characterized by protrusion of the posterior or anterior walls of the vagina, often both walls, which is accompanied by a number of unpleasant sensations and leads to many problems in various aspects of the quality of life, including in the sexual and social spheres.

This disease is more common in women mainly after 40 years, but it also occurs in young, nulliparous women (2%). Slowly progressing pathological condition causes constant suffering to women, reduces working capacity, leads to neuropsychic breakdowns, leads to the breakdown of family relationships.

The main role in the occurrence of the disease is played by the violation of synergism of the muscles of the pelvic floor, anterior abdominal wall, diaphragm, perineal tears in childbirth, damage and stretching of the muscles of the pelvic floor, congenital or acquired disorders in the processes of innervation.

Often, along with the anterior wall of the vagina, the bladder descends, and the prolapse and prolapse of the posterior wall of the vagina 8 leads to the prolapse of the anterior wall of the rectum. As a result of this, loss of urine occurs during exertion (coughing, lifting weights), involuntary emission of gases, constipation.

Most often, prolapse of the vagina is observed in older women as a result of involutional processes in the genitals inherent in old age. Often there is complete or incomplete prolapse of the vagina and uterine body. This leads to unbearable suffering and is usually accompanied by incontinence of urine, feces or difficulty urinating.

The problem of urinary incontinence includes three factors: medical, social and economic. Every fourth woman in the world suffers from urinary incontinence, every eleventh woman is operated on for omission of genital organs and urinary incontinence. Of these, 30% of women are operated repeatedly.

Among conservative tactics for treating pelvic dysfunctions in women, urogynecological pessaries are widely known.

The history of vaginal pessaries dates back to the times of Hippocrates and Ambrasia Pare (16th century). And already in the 17th century, the Dutch surgeon Van Deventer described four types of "rings", which in the 18-20 centuries began to be made of rubber, latex, plastic and silicone. The latter material is most preferred. Existing pessaries differ in shape, size, material of manufacture, density and their inherent function.

There are supporting pessaries (ring, cup-shaped, etc.) [1, 2, 3, 4] and pessaries filling the internal space (cube, inflatable, mushroom, etc.) [3, 4]. A special type of pessaries is a device used for urinary incontinence, namely, supporting pessaries with levator. A study of the existing varieties of pessaries and uterine rings revealed a number of drawbacks in their design and the accompanying complications in their use. The most common of these is the occurrence of discomfort and displacement of pessaries inserted into the vagina. This is primarily due to the inconvenient form of the pessary, the material from which it is made. The appearance of abundant vaginal discharge and the formation of ulcers on the cervix is also associated with the quality of the material used, its density, the possibility of infection and partial chemical decomposition.

Infringement, fistulas, urinary or intestinal obstruction are the result of the use of the unsuccessful form of pessaries [1, 2, 3, 4], increased density of materials used, strong elasticity and deformation during prolonged use. In addition, existing pessaries do not take into account such factors as a wide sexual gap, a short vaginal length, a combination of vaginal prolapse and stress urinary incontinence.

The disadvantage of existing uterine pessaries [1, 2, 3, 4] is the difficulty of their introduction by women themselves, especially in the older age group. All this makes us look for new forms of pessaries and new materials for their manufacture. This problem is solved by the presented new types of pessaries. The implementation of new models makes it easier to introduce the pessary into the vagina, to properly install it, to create additional ways of the outflow of the vaginal discharge, to reduce the area of contact of the pessary from the mucous wall of the vagina, to facilitate the removal of the pessary and the retention of the uterus, bladder and vagina, fixing the urethrovesical angle in the correct anatomical physiological position.

Known pessary (patent RU 2138229), made in the form of a hemisphere of elastic biopolymer material on the vaginal vault, characterized in that its thickened edge has grooves for chemical contraceptives and therapeutic agents.

The disadvantage of this pessary is the lack of additional ways for the outflow of the vaginal discharge, the increased area of contact of the pessary with the mucous wall of the vagina, the inability to fix the urethrovesical angle in the correct anatomical and physiological position.

The closest solution is the Juno pessary [5], made in the form of a ring located at the edges of the cup with a central hole, and containing holes for the outflow of the vaginal discharge along the perimeter of the central hole.

The Juno uterine pessary is made of dense inert plastic and is used to conservatively correct the prolapse and prolapse of the female genital organs.

The disadvantage of this pessary is the lack of fixation of the urethrovesical angle in the correct anatomical and physiological position, insufficiently effective outflow of the vaginal discharge, the complexity and inconvenience of extracting the pessary from the vagina.

The technical result of this solution is a device that is easily inserted into the vagina and is also easily removed from it, allows you to keep the body and cervix in the correct anatomical position, prevents the lowering of the walls of the vagina, prevents involuntary urination and urinary incontinence with tension, coughing, sneezing and lifting weights . In addition, the device provides the ability to fix the urethrovesical angle in the correct anatomical and physiological position, reduces the area of contact of the pessary with the mucous wall of the vagina, effectively ensures the outflow of the vaginal discharge.

The claimed technical result is achieved due to the fact that the pessary, made in the form of a ring of silicone, characterized in that it contains at least two cutouts from the edges of the ring.

The cuts from the edges of the ring are preferably made with a symmetrical arrangement. Also preferably contains cuts on the inside of the ring, round or triangular in shape.

The pessary can be made containing a cup with a central hole on the inside of the ring, having additional oval holes along its perimeter.

The utility model is illustrated in the drawing.

Figure 1 shows examples of the structural design of the pessary, where 1 is a ring, 2 is a cutout on the outside of the ring, 3 is a cutout on the inside of a round-shaped ring, 4 is a cutout on the inside of a ring of a triangular shape, 5 is a hole in the cup area, 6 - a cup attached to the ring.

Utility Model Implementation

The utility model may be made in the form of a ring of silicone, preferably high-quality silicone of a certain elasticity and density, specially selected for optimal use as a pessary.

A distinctive feature of the device is the performance of cutouts along the boundaries of the ring. A prerequisite is the presence of cutouts 2 on the outside of the ring. Cutouts should be at least two (see Figure 1 (a, b, c)), but can be up to four (see Figure 1 (d)) or more.

Cutouts can be made from the edges of the ring, preferably made with a symmetrical arrangement.

Also, cutouts can be made on the inside of the ring. These internal cutouts can be made both rounded 3, and triangular in shape 4. The pessary can contain on the inside of the ring a cup 6 with a central hole having additional holes 5 along its perimeter. The cup is a conical cavity fixed with a large diameter to the borders of the ring 1. Additional holes 5 around the perimeter of the cup 6 serve to drain the vaginal discharge.

Cutouts 3, 4 on the inner side of the ring are preferably made with a symmetrical arrangement.

Cutouts from the inner 3, 4 and outer 2 sides of the ring allow you to conveniently grab and compress the device. Cutouts 3, 4 on the inner side of the ring give additional elasticity with pressure on the walls of the vagina.

Cutouts 2, 3, 4 serve for the convenience of gripping and compressing the pessary when inserted into the vagina. Also, cutouts 2 on the outer side of the ring reduce the area of contact of the pessary with the mucous membrane of the vaginal walls (prevention of pressure sores) and are additional openings for free outflow of the vaginal discharge and easy removal of the pessary from the vaginal cavity by the woman herself.

The above properties of the device are also partially ensured by the fact that the pessary pressures on the walls of the vagina in the area of its dome and prevents it from moving down to the genital slit of the body and neck, uterus, vagina and bladder.
