Abstract

The invention relates to a medical connector for liquid conduits and a lock for said connector, whereby the lock (3) can be screwed onto the female coupling (2) of the connector (1, 2, 3). Moreover, the elastic transverse deformation capacity of the aforementioned lock is such that the screwing of the lock onto the female coupling causes said elastic deformation which, in turn, tightens the lock on the female coupling. The invention is particularly suitable for connectors comprising two standardised couplings, namely a male and female coupling.

Description

L'invention concerne les connecteurs à usage médical pour raccorder des conduits de liquide, qui comprennent un raccord tubulaire conique mâle, un raccord tubulaire conique femelle dans lequel peut s'emboîter le raccord mâle, et un verrou tubulaire monté mobile sur le raccord mâle et vissable sur le raccord femelle pour maintenir les deux raccords emboîtés . The invention relates to connectors for medical use for connecting liquid conduits, which comprise a male conical tubular connector, a female conical tubular connector into which the male connector can fit, and a tubular latch mounted movably on the male connector and screwable onto the female fitting to keep the two fittings nested.

Les cônes mâle et femelle et le verrou vissable sont normalisés (EN 20594-1, EN 1707) . La figure 1 du dessin joint est un schéma d'une réalisation connue d'un tel connecteur, vue en coupe axiale .The male and female cones and the screw lock are standardized (EN 20594-1, EN 1707). Figure 1 of the accompanying drawing is a diagram of a known embodiment of such a connector, seen in axial section.

On a représenté sur cette figure l'extrémité (la) du raccord tubulaire conique mâle (1), l'extrémité (2a) du raccord tubulaire conique femelle (2) , et le verrou tubulaire (3) monté à coulisse sur l'extrémité (la) du raccord mâle. Le raccord mâle présente une collerette externe (lb) qui constitue un arrêtoir pour le verrou qui présente un épaulement interne (3b) en sorte que le contact de l' épaulement avec la collerette détermine une position de fin de course du verrou. Le verrou présente également un filetage intérieur (3a) apte à coopérer avec le filetage extérieur correspondant (2b) du raccord femelle pour visser le verrou sur le raccord femelle. A l'état vissé, le verrou est bloqué et serré contre l' arrêtoir qui est encastré dans le verrou, ce qui constitue une liaison forte « A » entre le verrou et le raccord mâle.This figure shows the end (la) of the male conical tubular connector (1), the end (2a) of the female conical tubular connector (2), and the tubular latch (3) mounted to slide on the end. (the) of the male connector. The male connector has an external flange (lb) which constitutes a stop for the latch which has an internal shoulder (3b) so that the contact of the shoulder with the flange determines an end position of the lock. The lock also has an internal thread (3a) capable of cooperating with the corresponding external thread (2b) of the female connector to screw the lock onto the female connector. In the screwed state, the lock is blocked and tightened against the retainer which is embedded in the lock, which constitutes a strong connection "A" between the lock and the male connector.

Les filetages du raccord femelle et du verrou par contre sont conçus en sorte qu'il y ait un jeu entre eux ce qui constitue une liaison faible « B » entre le verrou et le raccord femelle.The threads of the female connector and the lock, on the other hand, are designed so that there is play between them, which constitutes a weak connection "B" between the lock and the female connector.

On obtient ainsi un bon blocage du verrou sur le raccord mâle pour empêcher un dévissage accidentel . Par contre, une rotation involontaire du raccord femelle peut entraîner une déconnexion de ce raccord par rapport au verrou.This gives good locking of the lock on the male connector to prevent accidental unscrewing. Through against, an involuntary rotation of the female connector can cause a disconnection of this connector relative to the lock.

La publication EP 0 204311 décrit un connecteur dans lequel le filet du verrou qui assurera le vissage par coopération avec un filet du raccord femelle est déformable au vissage.The publication EP 0 204311 describes a connector in which the thread of the lock which will ensure the screwing by cooperation with a thread of the female connector is deformable when screwed.

On diminue ainsi les risques d'une déconnexion du raccord mais au prix d'une conception très particulière du filet de serrage du verrou auquel on donne une forme polygonale que le serrage déforme radialement en n'assurant que des contacts de serrage localisés avec le filet coopérant du raccord femelle sauf à donner également au filet du raccord femelle une forme particulière, nécessitant par conséquent une fabrication spécifique de ce raccord .This reduces the risk of disconnection of the fitting, but at the cost of a very specific design of the lock tightening thread, which is given a polygonal shape that the tightening deforms radially, ensuring only localized tightening contacts with the thread. cooperating with the female connector except also giving the thread of the female connector a particular shape, therefore requiring specific manufacture of this connector.

La présente invention vise à définir un verrou déformable au serrage, mais assurant un serrage circulaire, pouvant convenir pour un raccord femelle normalisé.The present invention aims to define a deformable lock tightening, but ensuring a circular tightening, which may be suitable for a standardized female connector.

On y parvient selon l'invention avec un connecteur dans lequel le fond du filet du verrou déformable est incliné sur l'axe du verrou, le verrou présentant une capacité de déformation élastique telle qu'à l'état vissé, le fond de ce filet est devenu, par déformation du verrou, sensiblement parallèle à l'axe du verrou et au contact du filet coopérant du raccord femelle.This is achieved according to the invention with a connector in which the bottom of the thread of the deformable lock is inclined on the axis of the lock, the lock having an elastic deformation capacity such that in the screwed state, the bottom of this thread has become, by deformation of the lock, substantially parallel to the axis of the lock and in contact with the cooperating thread of the female connector.

De préférence, le verrou présente encore une ou plusieurs des caractéristiques suivantes : - Les sommets des filets du verrou sont coniques,Preferably, the lock also has one or more of the following characteristics: - The tops of the threads of the lock are conical,

- Le filetage du verrou est à pas variable pour réaliser un serrage sur les côtés des filets. On décrira ci après un exemple de réalisation d'un connecteur selon l'invention en référence aux figures du dessin joint sur lequel :- The thread of the lock is of variable pitch to tighten the sides of the threads. An exemplary embodiment of a connector according to the invention will be described below with reference to the figures of the attached drawing in which:

- la figure 1 est un schéma de la zone d'emboîtement d'un raccord mâle dans un raccord femelle dans le cas d'un connecteur connu ;- Figure 1 is a diagram of the nesting area of a male connector in a female connector in the case of a known connector;

- la figure 2 est un schéma d'un verrou selon l'invention ;- Figure 2 is a diagram of a lock according to the invention;

- les figures 3 et 4 sont des schémas du verrou de la figure 2 respectivement à l'état non déformé et à 1 ' état déformé ;- Figures 3 and 4 are diagrams of the lock of Figure 2 respectively in the non-deformed state and 1 deformed state;

- la figure 5 est un schéma du verrou de la figure 2 représenté à la fois à l'état non déformé (traits continus) et à l'état déformé (traits interrompus) ;- Figure 5 is a diagram of the lock of Figure 2 shown both in the undeformed state (solid lines) and in the deformed state (broken lines);

- la figure 6 est un schéma analogue à celui de la figure 1 dans le cas d'un connecteur comportant un verrou selon l'invention ;- Figure 6 is a diagram similar to that of Figure 1 in the case of a connector having a lock according to the invention;

- la figure 7 est une vue général du connecteur de la figure 6, etFIG. 7 is a general view of the connector of FIG. 6, and

- la figure 8 est un schéma de la partie centrale du connecteur de la figure 6 vue en coupe, etFIG. 8 is a diagram of the central part of the connector of FIG. 6 seen in section, and

- la figure 9 est une autre vue du verrou montrant la forme en hélice des filets. Les figures 2 à 5 montrent le verrou de l'invention.- Figure 9 is another view of the lock showing the helical shape of the threads. Figures 2 to 5 show the lock of the invention.

Le verrou est vu au repos en coupe axiale (figure 2) et en coupe axiale limitée au plan de coupe respectivement au repos (figure 3) et après déformation (figure 4) . Dans l'exemple représenté, le verrou (3) a un filetage constitué de deux filets (4, 5) dont les fonds ont été repérés (4a, 5a) et les sommets (4b, 5b) .The lock is seen at rest in axial section (Figure 2) and in axial section limited to the section plane respectively at rest (Figure 3) and after deformation (Figure 4). In the example shown, the lock (3) has a thread made up of two threads (4, 5), the bottoms of which have been identified (4a, 5a) and the tops (4b, 5b).

Si en service le vissage doit se faire sur le filet 4, le fond (4a) de ce filet est par fabrication incliné sur l'axe du verrou en sorte qu'à l'état vissé (figure 4), ce fond soit devenu sensiblement parallèle à l'axe.If in service the screwing must be done on the thread 4, the bottom (4a) of this thread is inclined by manufacture on the axis of the lock so that in the screwed state (Figure 4), this bottom has become substantially parallel to the axis.

Des dispositions similaires peuvent être adoptées pour le deuxième filet (5) . Les sommets (4b, 5b) des filets sont arrondis en demi-cercle .Similar arrangements can be made for the second net (5). The vertices (4b, 5b) of the nets are rounded in a semicircle.

La figure 5 montre le verrou au repos (traits continus) et à l'état déformé (traits interrompus) .Figure 5 shows the latch at rest (solid lines) and in the deformed state (broken lines).

Sur ces figures, les références sont les mêmes que pour les figures 1 et 2.In these figures, the references are the same as for Figures 1 and 2.

Le verrou est réalisé dans un matériau qui permet cette déformation élastique, par exemple en élastomère thermoplastique comme les polyether block amides vendus sous la marque PEBAX par ELF ATOCHEM. Ces assemblages à verrouillage des connecteurs du domaine médical étant normalisés, il convient, pour que le verrou de l'invention puisse être utilisé dans les assemblages normalisés que les dimensions du verrou venu de fabrication soient telles qu'à l'état déformé, les dimensions du verrou correspondent à celle d'un verrou normalisé. Il en résulte que le diamètre d'entrée du verrou de l'invention à l'état non déformé est inférieur au diamètre d'entrée du verrou normalisé correspondant.The lock is made of a material which allows this elastic deformation, for example in thermoplastic elastomer such as the polyether block amides sold under the brand PEBAX by ELF ATOCHEM. These locking assemblies of connectors from the medical field being standardized, it is appropriate, so that the lock of the invention can be used in standardized assemblies, that the dimensions of the bolt produced are such that in the deformed state, the dimensions of the lock correspond to that of a standard lock. As a result, the inlet diameter of the lock of the invention in the non-deformed state is less than the inlet diameter of the corresponding standardized lock.

De préférence, selon l'invention le diamètre du verrou au niveau de l' épaulement (3b) est choisi supérieur au diamètre de la collerette (lb) du raccord mâle en sorte que ce raccord puisse tourner par rapport au raccord femelle à l'état verrouillé si bien qu'une rotation accidentelle du raccord mâle n'a pas d'incidence sur le vissage.Preferably, according to the invention the diameter of the bolt at the shoulder (3b) is chosen to be greater than the diameter of the flange (lb) of the male connector so that this connector can rotate relative to the female connector in the state locked so that accidental rotation of the male connector does not affect the screwing.

Pour dévisser le verrou, il faut impérativement tenir le verrou mâle d'une main et le raccord femelle de l'autre main, ce qui exclut toute possibilité de dévissage accidentel par une simple rotation du raccord femelle.To unscrew the lock, it is imperative to hold the male lock with one hand and the female connector with the other hand, which excludes any possibility of accidental unscrewing by a simple rotation of the female connector.

La figure 6 du dessin joint est un schéma en coupe analogue à la figure 1 d'un raccord conforme à l'invention, et la figure 7 est un schéma du raccord complet à l'état de service.Figure 6 of the accompanying drawing is a sectional diagram similar to Figure 1 of a connector according to the invention, and Figure 7 is a diagram of the complete connector in service.

Sur la figure 8, on a fait apparaître l'emboîtement du raccord mâle dans le raccord femelle. De façon en soi connue les surfaces en contact (10, 20) des deux raccords dans la zone d'emboîtement sont faiblement coniques (conicite luer) .In Figure 8, we have shown the socket of the male connector in the female connector. In a manner known per se, the contact surfaces (10, 20) of the two connectors in the interlocking zone are slightly conical (conical luer).

La figure 9 est une vue du verrou différente de celle de la figure 2 du fait que le plan de vue n'est pas le même . L'invention n'est pas limitée à la réalisation qui a été décrite. Figure 9 is a view of the lock different from that of Figure 2 in that the view plane is not the same. The invention is not limited to the embodiment which has been described.
