Description

DISPOSITIF D'ÉTANCHÉITÉ POUR UNE CARPULE . SEALING DEVICE FOR A CARPULE.
La présente invention a pour objet un dispositif d'étanchéité destiné en particulier, mais non exclusivement, aux carpules ou cartouches d'injection contenant notamment des anesthésiques .The present invention relates to a sealing device intended in particular, but not exclusively, for injection cartridges or cartridges containing in particular anesthetics.
Ces cartouches destinées à être montées sur une seringue sont constituées par un petit tube, généralement en verre dont le fond comporte un piston mobile destiné à chasser le liquide dans une aiguille creuse. Avant insertion de l'aiguille, la partie avant de la cartouche est obturée par un opercule ou obturateur de caoutchouc qui sera traversé par l'aiguille, assujetti sur le tube au moyen d'une bague ou anneau métallique sertie sur 1 ' avant du tube .These cartridges intended to be mounted on a syringe consist of a small tube, generally made of glass, the bottom of which comprises a movable piston intended to expel the liquid in a hollow needle. Before inserting the needle, the front part of the cartridge is closed by a rubber seal or shutter which will be crossed by the needle, secured to the tube by means of a ring or metal ring crimped on the front of the tube .
Une telle construction permet une étanchéité convenable lors du stockage et du transport des cartouches, la pression étant équilibrée de part et d'autre de l'obturateur. Par contre, il est d'observation courante que, lors de l'application d'une pression sur le fond de la cartouche, l'aiguille ayant été au préalable montée sur la cartouche, une fuite se produit entre le disque d'obturation et la bague métallique. Cette fuite se produit à la périphérie de l'obturateur en caoutchouc et la bague métallique. En effet, la pression appliquée sur le fond de la carpule est transmise par le liquide et tend à décoller le disque obturateur du siège constitué par la partie avant du tube, le liquide passant alors entre le siège et la paroi arrière de 1 ' obturateur .Such a construction allows a suitable seal during storage and transport of the cartridges, the pressure being balanced on either side of the shutter. On the other hand, it is common observation that, when pressure is applied to the bottom of the cartridge, the needle having been previously mounted on the cartridge, a leak occurs between the shutter disc and the metal ring. This leak occurs at the periphery of the rubber shutter and the metal ring. In fact, the pressure applied to the bottom of the cartridge is transmitted by the liquid and tends to take off the obturator disc from the seat formed by the front part of the tube, the liquid then passing between the seat and the rear wall of the obturator.
Il a déjà été proposé d'améliorer l' étanchéité des cartouches munies de moyens d'étanchéité pour assurer 1 ' asepsie des produits .It has already been proposed to improve the sealing of the cartridges provided with sealing means to ensure the asepsis of the products.
AU-A-603 862 décrit une couronne ayant pour rôle de centrer la membrane en caoutchouc . Dans US-A- 1,993,629 une collerette provoque la déformation d'un bloc de caoutchouc assurant la fermeture avant du tube de verre.AU-A-603 862 describes a crown having the role of centering the rubber membrane. In US-A-1,993,629 a collar causes the deformation of a rubber block ensuring the front closure of the glass tube.
US-A- 2,157,503 une collerette présente une section à angle aigu mais ni sa fonction, ni les rapports de dimensions avec le tube ne sont définis.US-A- 2,157,503 a flange has a section at an acute angle but neither its function nor the dimension ratios with the tube are defined.
Ces trois documents ne concernent que des seringues manuelles c'est-à-dire agissant sous une pression relativement faible.These three documents relate only to manual syringes, that is to say acting under relatively low pressure.
L'objet de l'invention est de pallier l'inconvénient signalé ci-dessus même en cas de forte pression appliquée et de permettre des injections sans fuites, même lorsque des pressions importantes sont nécessaires, par exemple en cas d'injections intradiploïques , intraligamentaires , intraseptales, intrapalatines, etc. Elle repose sur l'idée que pour assurer 1 ' étanchéité sous forte pression il est nécessaire d'obtenir la compression d'une membrane souple entre deux arêtes de pièces indéformables .The object of the invention is to overcome the drawback indicated above even in the case of high pressure applied and to allow injections without leakage, even when significant pressures are necessary, for example in the case of intradiploic, intraligamentary injections. , intraseptales, intrapalatines, etc. It is based on the idea that to ensure sealing under high pressure it is necessary to obtain compression of a flexible membrane between two edges of non-deformable parts.
Selon l'invention, le dispositif d'étanchéité d'une seringue dans laquelle est insérée une cartouche, fermée à sa partie supérieure par un obturateur souple, reliée à une aiguille d'injection, est caractérisé en ce que la pièce de liaison entre 1 ' aiguille et la partie avant de la cartouche présente une couronne en saillie dont le diamètre est sensiblement égal au diamètre de 1 ' ouverture de la cartouche venant porter contre 1)obturateur souple pour le presser contre le bord interne de la surface supérieure de la cartouche.According to the invention, the sealing device of a syringe in which a cartridge is inserted, closed at its upper part by a flexible obturator, connected to an injection needle, is characterized in that the connecting piece between 1 'needle and the front part of the cartridge has a projecting crown whose diameter is substantially equal to the diameter of one opening of the cartridge coming to bear against 1) flexible shutter to press it against the inner edge of the upper surface of the cartridge .
Ainsi, lorsqu'une pression est appliquée sur le fond de la carpule, la couronne applique fermement le disque contre le bord supérieur de 1 ' ouverture en déformant celui-ci ce qui évite toute fuite. La pièce de liaison entre l'aiguille et la cartouche peut être soit un adaptateur de montage de l'aiguille sur une seringue ou porte-aiguille, soit la pièce surmoulée en matière plastique entourant 1 ' aiguille proprement dite. Sur certaines seringues, le porte-aiguille, intégré dans la partie avant par moulage, peut présenter la même disposition..Thus, when pressure is applied to the bottom of the cartridge, the crown firmly applies the disc against the upper edge of the opening, deforming the latter which prevents any leakage. The connecting piece between the needle and the cartridge can be either an adapter for mounting the needle on a syringe or needle holder, or the piece overmolded plastic surrounding the needle itself. On some syringes, the needle holder, integrated in the front part by molding, can have the same arrangement.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre de modes particuliers de réalisation, donnés uniquement à titre d'exemple non limitatif, en regard des dessins qui représentent :Other characteristics and advantages of the invention will appear during the description which follows of particular embodiments, given solely by way of nonlimiting example, with reference to the drawings which represent:
- La figure 1, une vue de la partie supérieure d'une cartouche de l'art antérieur;- Figure 1, a view of the upper part of a cartridge of the prior art;
- la figure 2, une vue de la déformation de l'obturateur dans un injecteur conforme à l'invention;- Figure 2, a view of the deformation of the shutter in an injector according to the invention;
- la figure 3, vue d'une aiguille selon l'invention.- Figure 3, view of a needle according to the invention.
La figure 1 représente le haut d'une cartouche d'anesthésique 1 par exemple en verre de type connu. Elle présente un bord supérieur plat 2 contre lequel repose un obturateur souple 3 en caoutchouc, néoprène ou analogue. L'obturateur 3 est maintenu contre la surface 2 par une bague métallique 5 dont la partie inférieure est sertie dans une gorge 4 de la cartouche 1. L'orifice central supérieur 6 de la cartouche 1 est ainsi obturé par l'obturateur 3. L'aiguille creuse non représentée sur la figure 1 traverse l'obturateur pour conduire le liquide au point d'injection. Lorsque, l'aiguille étant en place, une pression est appliquée sur le fond de la cartouche (non représenté), la paroi supérieure de 1 ' obturateur est appliquée fermement contre le bord interne de la bague métallique sertie 5 ce qui a tendance à décoller 1 ' obturateur du siège constitué par la surface supérieure 2 de la cartouche d'où les fuites qui se produisent à peu près systématiquement. La présente invention vise à établir une liaison étanche au voisinage du bord 7 de la surface supérieure 2 de la cartouche.FIG. 1 shows the top of an anesthetic cartridge 1, for example made of glass of known type. It has a flat upper edge 2 against which rests a flexible shutter 3 made of rubber, neoprene or the like. The shutter 3 is held against the surface 2 by a metal ring 5, the lower part of which is crimped into a groove 4 of the cartridge 1. The upper central orifice 6 of the cartridge 1 is thus closed by the shutter 3. L 'hollow needle not shown in Figure 1 through the shutter to lead the liquid to the injection point. When, with the needle in place, pressure is applied to the bottom of the cartridge (not shown), the upper wall of the shutter is applied firmly against the internal edge of the crimped metal ring 5 which tends to take off 1 shutter of the seat formed by the upper surface 2 of the cartridge where the leaks which occur almost systematically. The present invention aims to establish a sealed connection in the vicinity of the edge 7 of the upper surface 2 of the cartridge.
Dans de nombreuses seringues 1 ' aiguille est montée dans un porte-aiguille tel que celui qui est représenté sur la figure 2. L'aiguille est insérée dans le porte-aiguille 8 sur lequel elle est généralement vissée sur le filetage 16 et le porte-aiguille est ensuite glissé sur 1 ' avant de la seringue où il est maintenu par friction. Le coulissement du porte-aiguille provoque le passage de l'aiguille à travers l'obturateur 3. La référence 10 représente le canal de passage de l'aiguille proprement dite. De préférence, la jupe inférieure 11 du porte-aiguille présente des godrons 12 qui facilitent le glissement du porte-aiguille sur la carpule et assurent une liaison mécanique efficace.In many syringes the needle is mounted in a needle holder such as that shown in the Figure 2. The needle is inserted into the needle holder 8 on which it is generally screwed onto the thread 16 and the needle holder is then slid on one before the syringe where it is held by friction. The sliding of the needle holder causes the needle to pass through the shutter 3. The reference 10 represents the passage channel of the needle itself. Preferably, the lower skirt 11 of the needle holder has gadroons 12 which facilitate the sliding of the needle holder on the cartridge and ensure an effective mechanical connection.
Conformément à l'invention, le porte-aiguille 8 présente au- dessous du canal 10 une couronne 9 en saillie dont le diamètre est sensiblement égal au diamètre de 1 ' orifice 6 de la cartouche 1 et dont la hauteur est, par exemple de 1,5 millimètre. Comme cela apparaît sur la figure 2, cette couronne d'étanchéité 9 appuie selon une zone de même dimension sur l'obturateur 3 de sorte que celui-ci prend la forme représentée sur la figure avant une injection. C'est- à-dire que la partie centrale de l'obturateur 3 prend la forme d'une lentille biconvexe. Cette déformation presse 1 ' obturateur contre le bord interne 7 de la cartouche 1 et contre un anneau de la partie interne du bord 2. Il se forme ainsi une zone d'étanchéité qui s'oppose à toute fuite. Dans le mode de réalisation précédent, l'aiguille était montée sur la carpule au moyen d'un porte-aiguille 8. L'aiguille proprement dite est habituellement entourée par une pièce plastique surmoulée qui permet sa fixation dans le porte-aiguille sans qu ' il soit nécessaire de la toucher avec la main. La présente invention peut également être mise en oeuvre lorsque 1 ' aiguille est montée directement sur la carpule. Une telle aiguille est représentée sur la figure 3. Elle comporte un canal creux 13 métallique sur laquelle est surmoulée une pièce 14 en matière plastique. La pièce de montage 14 dont l'avant est tronconique présente une jupe inférieure 15, légèrement conique, munie de godrons 12 permettant de glisser la jupe 15 contre la paroi externe de la cartouche 1. Contrairement aux aiguilles connues, la jupe n'est pas munie d'un filetage interne qui, dans le mode de réalisation précédent permettait d'assujettir l'aiguille sur le filetage 16 du porte-aiguille 8. Par contre, la pièce 14 comporte une couronne d'étanchéité 9 qui joue le même rôle que dans 1 ' exemple précédent .According to the invention, the needle holder 8 has below the channel 10 a projecting crown 9 whose diameter is substantially equal to the diameter of one orifice 6 of the cartridge 1 and whose height is, for example 1 , 5 millimeter. As shown in FIG. 2, this sealing ring 9 presses on a shutter of the same dimension on the shutter 3 so that the latter takes the shape shown in the figure before an injection. That is to say that the central part of the shutter 3 takes the form of a biconvex lens. This deformation presses the shutter against the internal edge 7 of the cartridge 1 and against a ring of the internal part of the edge 2. A sealing zone is thus formed which prevents any leakage. In the previous embodiment, the needle was mounted on the cartridge by means of a needle holder 8. The needle itself is usually surrounded by a molded plastic part which allows its fixing in the needle holder without it must be touched with the hand. The present invention can also be implemented when the needle is mounted directly on the cartridge. Such a needle is shown in Figure 3. It has a hollow metal channel 13 on which is molded a piece 14 of plastic. The mounting piece 14, the front of which is frustoconical, has a slightly conical lower skirt 15, provided with gadroons 12 allowing the skirt 15 to slide against the external wall of the cartridge 1. Unlike the known needles, the skirt is not fitted with an internal thread which, in the previous embodiment made it possible to subject the needle to the thread 16 of the needle holder 8. On the other hand, the part 14 includes a sealing ring 9 which plays the same role as in the previous example.
Il va de soi que de nombreuses variantes peuvent être apportées, notamment par substitution de moyens techniques équivalents, sans sortir pour cela du cadre de l'invention. It goes without saying that many variants can be made, in particular by substitution of equivalent technical means, without departing from the scope of the invention.
