Une fois placés en milieu humide, les tampons périodiques sont capables d'augmenter considérablement de volume du fait du caractère fortement absorbant du matériau fibreux qui les constitue; mais en fin de règles, il peut se produire, en raison justement de ce caractère fortement absorbant, un assèchement des muqueuses et des difficultés Once placed in a humid environment, the periodic pads are capable of considerably increasing in volume due to the highly absorbent nature of the fibrous material which constitutes them; but at the end of menstruation, there may occur, precisely because of this highly absorbent character, drying of the mucous membranes and difficulties

Un tel revêtement, s'il rend effectivement plus aisée l'introduction ou l'extraction après usage du tampon périodique, présente néanmoins l'inconvénient de réduire sensiblement la pénétration des fluides corporels dans le tampon dans sa zone qui est enduite de lubrifiant. C'est pour cette raison que, dans le brevet français considéré, on ne proposait d'appliquer la substance lubrifiante que vinyl. Such a coating, if it actually makes it easier to insert or extract after using the periodic tampon, nevertheless has the drawback of substantially reducing the penetration of bodily fluids into the tampon in its area which is coated with lubricant. It is for this reason that, in the French patent under consideration, it was proposed to apply the lubricant only

Pour effectuer l'enduction du tampon périodique selon l'invention, la poudre ou farine de l'agent épaississant ou gélifiant choisi est mise en solution dans l'eau de façon à former une solution visqueuse contenant d'environ 1 à environ 10% en poids d'agent par rapport au poids total de la solution. Une telle solution est appliquée lium. The thickeners or gelling agents listed above are generally available commercially in the form of powder or flour. To coat the periodic buffer according to the invention, the powder or flour of the thickening or gelling agent chosen is dissolved in water so as to form a viscous solution containing from about 1 to about 10% in weight of agent relative to the total weight of the solution. Such a solution is applied

En se référant au dessin, on voit que l'on a désigné par 1, un injecteur de type classique consistant en un élément cylindrique 2 et en un piston 3 apte à coulisser l'intérieur dudit élément. Dans l'élément cylindrique 2, est aussi logé un tampon périodique 4 selon l'invention. Pour des raisons de clarté, le tampon périodique 4 est représenté Referring to the drawing, it can be seen that there has been designated by 1, a conventional type injector consisting of a cylindrical element 2 and a piston 3 capable of sliding the interior of said element. In the cylindrical element 2, is also housed a periodic buffer 4 according to the invention. For reasons of clarity, the periodic buffer 4 is shown

roi latérale du tampon périodique 4 comporte quatre replis 5, qui se présentent, vus de l'extérieur, comme des rainures ménagées dans la paroi du tampon 4. Les quatre replis 5 sont parallèles à l'axe du tampon 4; ils sont répartis sur cet élément tous les 90 ; la longueur du tampon périodique 4 lateral king of the periodic tampon 4 comprises four folds 5, which appear, seen from the outside, like grooves made in the wall of the tampon 4. The four folds 5 are parallel to the axis of the tampon 4; they are distributed on this element every 90; the length of the periodic buffer 4
est d'environ 5 cm et son diamètre extérieur mesuré en de- is about 5 cm and its outside diameter measured below

Dans cet exemple, la solution d'enduction ci-dessus est appliquée sur la paroi latérale du tampon périodique 4, une fois que ce dernier a été fortement comprimé et que les replis 5 ont été formés. L'agent épaississant ou gélifiant forme ainsi sur chaque zone de la paroi latérale du tampon 4 qui est To apply the thickening or gelling agent, an aqueous solution of the thickening or gelling agent is prepared containing by weight from 1 to 7 of said agent. In this example, the above coating solution is applied to the side wall of the periodic tampon 4, once the latter has been strongly compressed and the folds 5 have been formed. The thickening or gelling agent thus forms on each zone of the lateral wall of the pad 4 which is

On observe que la couche d'agent épaississant ou gélifiant a pour effet de faciliter l'introduction et la mise en place du tampon périodique 4. En présence de fluides corporels, la couche d'agent épaississant ou gélifiant forme un milieu gélatineux qui ne s'oppose pas à la pénétration desdits fluides à l'intérieur du tampon périodique 4 et qui, en même temps, maintient une certaine humidité au contact des muqueuses, conjurant tous risques d'irritation.

In the presence of body fluids, the layer of thickening or gelling agent forms a gelatinous medium which does not 'not oppose the penetration of said fluids inside the periodic buffer 4 and which, at the same time, maintains a certain humidity in contact with the mucous membranes, warding off any risk of irritation.
