Abstract
Description
Valve. Valve.
La présente invention concerne une valve qui est de construction très simple, tout en étant efficace. The present invention relates to a valve which is of very simple construction, while being effective.
Cette valve est caractérisée en ce qu'elle comporte, un corps tubulaire dont une extrémité est semi-torique, et un manchon qui est fixé sur le corps, dont une extrémité est fermée par une membrane souple se trouvant à proximité de l'éextrémité semi-torique du corps, et dont la paroi latérale est percée, au voisinage de la membrane, d'un ou plusieurs trous permettant le passage d'un fluide dans le corps quand la membrane est écartée de l'extrémité semi-torique de ce corps. This valve is characterized in that it comprises a tubular body, one end of which is semi-toric, and a sleeve which is fixed to the body, one end of which is closed by a flexible membrane located near the semi-end. -torique of the body, and the side wall of which is pierced, in the vicinity of the membrane, with one or more holes allowing the passage of a fluid in the body when the membrane is separated from the semi-toric end of this body .
Cette valve est destinée à être montée sur la paroi d'une enceinte devant contenir un fluide sous pression, en étant placée de façon que l'extrémité semi-torique du corps se trouve à l'intérieur. This valve is intended to be mounted on the wall of an enclosure which must contain a pressurized fluid, being placed so that the semi-toric end of the body is inside.
Le fluide sous pression contenu dans l'enceinte tend alors à appliquer la membrane sur cette extrémité, ce qui lsempêche de ressortir de l'enceinte. Pour remplir cette dernière, il suffit de disposer un embout de gonflage dans le corps et d'introduire par l'embout un fluide qui repousse la membrane et pénètre dans l'enceinte par le ou les trous ménagés dans la paroi latérale du corps.The pressurized fluid contained in the enclosure then tends to apply the membrane to this end, which prevents it from emerging from the enclosure. To fill the latter, it suffices to have an inflation nozzle in the body and to introduce through the nozzle a fluid which repels the membrane and enters the enclosure through the hole or holes made in the side wall of the body.
La valve selon l'invention trouve une application particulièrement intéressante dans les prothèses mammaires que l'on peut gonfler à l'aide, par exemple, d'un gel de silicone ou de sérum physiologique. On peut alors mettre en place la prothèse vide, ce qui réduit au minimum la longueur de la cicatrice, et remplir ensuite la prothèse à la demande. The valve according to the invention finds a particularly advantageous application in breast prostheses which can be inflated using, for example, a silicone gel or physiological serum. We can then place the empty prosthesis, which minimizes the length of the scar, and then fill the prosthesis on demand.
Dans le cas de l'application à une prothèse mammaire, une bande portant en son centre un bouchon pouvant s'engager dans l'ouverture du corps de la valve est fixée par ses extrémités sur la paroi de la prothèse au droit de la valve. Ce bouchon empêche la peau et le tissu conjonctif qui y adhère de former une saillie pénétrant dans l'ouverture du corps. In the case of application to a breast prosthesis, a strip carrying in its center a plug which can engage in the opening of the body of the valve is fixed by its ends to the wall of the prosthesis in line with the valve. This plug prevents the skin and the connective tissue that adheres to it from forming a protrusion entering the opening of the body.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation de la valve selon l'invention avec référence à la figure unique du dessin annexé qui est une vue en coupe de la valve montée sur une prothèse mammaire. An embodiment of the valve according to the invention has been described below, by way of nonlimiting example, with reference to the single figure of the appended drawing which is a sectional view of the valve mounted on a breast prosthesis.
Telle qu'elle est représentée au dessin, la valve selon l'invention comprend une bague 1, en élastomère de silicone, dont une extrémité la est semi-torique et qui comporte une gorge péri phérique 2. Dans cette gorge est encastrée une partie relativement épaisse d'un manchon 3, du même élastomère, qui est prolongé, au droit de cette partie épaisse, par une partie plus mince munie de trous 4 et fermée par une membrane mince 5; les trous 4 se trouvent a proximité immédiate de la membrane. La partie centrale de cette membrane est plus épaisse que sa partie périphérique. As shown in the drawing, the valve according to the invention comprises a ring 1, made of silicone elastomer, one end of which is semi-toric and which has a peripheral groove 2. In this groove is embedded a relatively thick of a sleeve 3, of the same elastomer, which is extended, in line with this thick part, by a thinner part provided with holes 4 and closed by a thin membrane 5; the holes 4 are located in the immediate vicinity of the membrane. The central part of this membrane is thicker than its peripheral part.
La valve est ici fixée sur la face interne de la paroi d'une prothèse mammaire 6, réalisée en une matière souple et élastique, en regard d'un orifice 7 percé dans cette paroi. Une bande 8 fixée par son extrémité sur la face externe de la prothèse, porte dans sa partie centrale un bouchon 9 engage à l'intérieur 10 de la Bague 1. The valve is here attached to the internal face of the wall of a breast prosthesis 6, made of a flexible and elastic material, opposite an orifice 7 drilled in this wall. A band 8 fixed by its end to the external face of the prosthesis, carries in its central part a plug 9 engaged inside 10 of the ring 1.
Pour gonfler la prothèse 6, on dégage le bouchon 9 de la partie intérieure de la bague 1 et on y place un embout par lequel on introduit dans la prothèse un liquide, par exemple du sérum physiologique. Lorsqu'on retire l'embout, la pression du liquide contenu dans la prothèse applique la membrane 5 sur la partie arrondie la de la bague 1, ce qui assure l'étanchéité. To inflate the prosthesis 6, the plug 9 is released from the inner part of the ring 1 and a tip is placed therein through which a liquid, for example physiological saline, is introduced into the prosthesis. When the tip is removed, the pressure of the liquid contained in the prosthesis applies the membrane 5 to the rounded part 1a of the ring 1, which ensures sealing.
Le bouchon 9 ne participe pas à l'étanchéité. Il empêche simplement le tissu humain qui recouvre la prothèse de pénétrer dans la partie intérieure 10 de la bague. The plug 9 does not participate in sealing. It simply prevents the human tissue which covers the prosthesis from entering the inner part 10 of the ring.
Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
