Definitions

  • the declared technical solution relates to medicine, namely, to medical devices that are inserted into the vagina to support organs, in particular, to correct prolapse of female pelvic organs.
  • a pessary according to document US2018296388 (Al) is known in the art, which has a collapsed state and an expanded state and is adapted to transition between these states. In the unfolded state, the pessary forms a three-dimensional structure that has a plurality of elastic arcs connected to each other. The device is inserted into the vagina in a folded state and unfolds.
  • the pessary is shaped like a ball/sphere, pear, box/cube/cube, ovoid, or the like.
  • ball is used, it can mean any conceivable three-dimensional shape suitable for prolapse correction.
  • the disadvantage of the known solution is the complexity of the design, the impossibility of controlling the process of deployment of the pessary after placing it in the vagina. In addition, as a result of the forced deployment of the pessary, the patient may experience pain.
  • a famous pessary urogynecological consists of two interconnected closed rings made of flexible elastic material.
  • the rings form a spatial body with a surface that surrounds it, approximately spherical or ovoid in shape.
  • the axial circles of the rings are placed in different planes.
  • Rings have outer diameters and inner diameters.
  • Said rings have different outer diameters and different inner diameters.
  • a ring with a smaller outer diameter is placed in a ring with a larger inner diameter and is rigidly connected to it in such a way that the rings have a single point of intersection of their axial circles.
  • the known technical solution due to the unevenness of the three-dimensional figure formed by the pessary rings, causes inconvenience when it is installed in the vagina. In particular, inconvenience is manifested in the uneven distribution of elasticity in the pessary. A ring with a larger diameter has less elasticity than a ring with a smaller diameter. This causes unevenness of the elasticity applied by the pessary, which causes inconvenience both when installing the pessary and during its wearing.

  • the pessary In a three-dimensional presentation of the pessary, it should be clear by skilled person that it consists of two closed rings connected together to form a spatial body.

  • the outer diameter is the same for two diametrically opposite points relative to the center of symmetry.

Therefore, we can say that the pessary as a spatial body has a spherical shape.
  • the difference in the value of the size of the outer diameter and the inner diameter is a constant value, which indicates the same thickness of the rings.
  • a flexible elastic material is used, which does not cause allergic reactions for most patients.

  • the place of compression of the pessary should be determined based on how the correction or prevention of prolapse is expected, that is, how the pessary will perform its function. However, in any case, the elastic rings of the pessary will support the pelvic organs with uniform tension even with unforced displacement of the pessary after installation.
  • the claimed invention showed its best properties when used for its intended purpose, in particular, the percentage of patients who felt discomfort when the pessary was inserted was insignificant. Additional studies showed that the cause of pain in this group of patients was the presence of inflammatory processes.
  • the proposed pessary combines the advantages of filling pessaries (cubic, mushroomshaped), which can adjust all three types prolapse (centrocele, isthmocele and rectocele ), but does not have a 12-hour limit in continuous use.
  • the pessary of the proposed form can be used continuously for up to 28 days. This reduces the need to visit a doctor, on the one hand, and removes the limitation of prolapse correction in elderly women who, for physical and/or mental reasons, cannot independently remove and install a pessary, enduring the 12-hour interval of its use.
  • the invention performed admirably as a means of correcting prolapse, as indicated by multiple surveys and a review of the control group.
  • the results of the surveys noted the relief of well-being and the naturalness of movements during the use of the pessary. This indicates that the pessary has significant design advantages over prior art solutions.
  • a skilled person will appreciate the design features and technical advantages of the claimed invention.

Abstract

L'invention propose une solution technique à utiliser en médecine, à savoir, des dispositifs médicaux qui sont insérés dans le vagin pour supporter des organes, en particulier, pour corriger le prolapsus pelvien chez la femme. Une forme du pessaire est formée par l'intersection de deux anneaux à angle droit, les points d'intersection étant diamétralement opposés par rapport au centre de symétrie commun des anneaux spécifiés.
