Abstract

A system allowing the exact knowledge of the position taken in the uterus of all the types of loops existing actually on the market. It comprises a marking device consisting in a centimetric coloring of the thread or threads which are affixed on all the types of loops. The invention can be utilised at the time when the loop is placed in position, to verify its location after its introduction, to cut the thread at the proper length with certitude and, at each of the periodic controls, to know exactly the positionning of the loop in the uterus.

Description

Système de graduation colorimétrique permettant de repérer la place d'un dispositif intra-utérin. Color grading system to identify the place of an intrauterine device.
La présente invention concerne tous les types de stérilet existant sur le marché et permet de connaître avec certitude la place de ce dispositif intra-utérin après le retrait de l'appareil introducteur.The present invention relates to all types of IUD existing on the market and allows to know with certainty the place of this intrauterine device after removal of the introducer.
Lors de la pose d'un stérilet, il est nécessaire d'effectuer une hystérométrie qui permet de connaître la distance précise de l'orifice externe du col de l'utérus à la paroi du fond utérin (figure I). Cette distance varie de 6 à IO cm et se décompose en deux parties : la cavité utérine où l'on doit déposer le stérilet et le col utérin (figure 2). La plupart des stérilets sont vendus avec de petits appareils introducteurs qui permettent de reporter les données de l'hystérométrie et de déposer le stérilet dans la cavité utérine. Tous les types de stérilet existant sur le marché sont terminés par un ou deux fils ne présentant aucun marquage. De tels dispositifs présentent l'inconvénient, après le retrait de l'appareil introducteur, de ne plus permettre de connaître avec exactitude la position du stérilet dans l'utérus. Il y a à ce moment perte des données de l 'hystérométrie initiale.When installing an IUD, it is necessary to perform a hysterometry which allows to know the precise distance from the external orifice of the cervix to the wall of the uterine fundus (figure I). This distance varies from 6 to 10 cm and is broken down into two parts: the uterine cavity where the IUD must be placed and the cervix (Figure 2). Most IUDs are sold with small introducers which allow the hysterometry data to be transferred and the IUD to be placed in the uterine cavity. All types of IUDs on the market are terminated by one or two wires without any marking. Such devices have the disadvantage, after the removal of the introducer, to no longer allow to know exactly the position of the IUD in the uterus. At this time, the data of the initial hysterometry is lost.
Le dispositif, suivant l'invention, permet d'éviter cet inconvénient. Dans celui-ci, en effet, un système de marquage et notamment une graduation colorimétrique permet à tout moment de connaître la place du stérilet dans l'utérus en faisant du ou des fils un instrument de mesure permanent.The device according to the invention avoids this drawback. In this one, in fact, a marking system and in particular a colorimetric graduation makes it possible at any time to know the place of the IUD in the uterus by making the son (s) a permanent measuring instrument.
Le dispositif, objet de l'invention, consiste à insérer sur l'extrémité inférieure des différents types de stérilet existant sur le marché en remplacement des fils d'origine, un ou plusieurs fils présentant un marquage et notamment par une graduation colorimétrique. Le système de graduation peut être réalisé notamment grâce à un changement de couleur chaque centimètre sur le ou les fils fixés sur tous les types de stérilet. A partir de l'extrémité inférieure du stérilet, on trouvera un fil présentant un centimètre noir ou incolore, un centimètre rouge, un centimètre jaune, un centimètre bleu, un centimètre vert, un centimètre orange, le reste du fil étant noir ou incolore.The device, object of the invention, consists in inserting on the lower end of the various types of IUD existing on the market in replacement of the original wires, one or more wires having a marking and in particular by a color grading. The graduation system can be achieved in particular by changing the color every centimeter on the wire or wires attached to all types of IUD. From the lower end of the IUD, there will be a wire with a black or colorless centimeter, a red centimeter, a yellow centimeter, a blue centimeter, a green centimeter, an orange centimeter, the rest of the wire being black or colorless.
Le dispositif, objet de l'invention, peut être utilisé tout d'abord lors de la pose du stérilet dans la cavité utérine après le retrait de l'appareil introducteur. Il permet dans ce cas de connaître avec exactitude la position du stérilet après le retrait de l'appareil introducteur et la tension du ou des fils terminaux. Il peut être utilisé ensuite lors de la pose du stérilet pour couper le ou les fils avec certitude à une longueur satisfaisante. Ceci est particulièrement intéressant car le fil ne doit pas être trop long car il risque d'entraîner une gêne, ni trop court car cela peut entraîner une disparition du fil dans l'utérus, ce qui nécessitera souvent une anésthésie générale pour enlever le stérilet. Dans ce cas, le système de graduation permet de tenir compte des données de l 'hystérométrie initiale. Enfin, le dispositif, objet de l'invention, peut être utilisé lors des contrôles périodiques car il permet avec certitude de connaître la place du stérilet. Ainsi, avec un stérilet de telle longueur et un utérus de telle profondeur, données connues au départ, si le fil sortant de l'orifice externe du col de l'utérus est bleu, le stérilet est en bonne place (figure 3), s'il est noir ou rouge, le stérilet est engagé dans le col de l'utérus et il est inefficace (figure 4), s'il est vert ou orange, il y a perforation de la paroi du fond utérin (figure 5). Ceci est évidemment très important car cela permet de savoir immédiatement si le stérilet est en place ou s'il est engagé dans le col utérin, auquel cas il n'est plus efficace. Si le stérilet s'est déplacé dans le col utérin, ce système permet de le replacer en le repoussant avec exactitude sans risque de perforation du fond utérin. The device, object of the invention, can be used first of all when the IUD is placed in the uterine cavity after removal of the introducer. It allows in this case to know exactly the position of the IUD after removal of the introducer and the tension of the terminal wire (s). It can then be used when installing the IUD to cut the wire (s) with certainty to a satisfactory length. This is particularly interesting because the wire should not be too long because it may cause discomfort, or too short because it can cause the wire to disappear in the uterus, which will often require general anesthesia to remove the IUD. In this case, the graduation system allows to take into account the data of the initial hysterometry. Finally, the device which is the subject of the invention can be used during periodic checks because it allows the place of the IUD to be known with certainty. Thus, with an IUD of such length and a uterus of such depth, data known at the outset, if the wire coming out of the external orifice of the cervix is blue, the IUD is in a good place (Figure 3), s 'it is black or red, the IUD is engaged in the cervix and it is ineffective (figure 4), if it is green or orange, there is perforation of the wall of the uterine fundus (figure 5). This is obviously very important because it allows you to know immediately if the IUD is in place or if it is engaged in the cervix, in which case it is no longer effective. If the IUD has moved into the cervix, this system allows it to be replaced by pushing it back exactly without the risk of perforation of the uterine fundus.
