Abstract

The present invention relates to a flexible pipe with a safety connecter, particularly for transporting gas for medical use, in which the connecter 1 includes an end-fitting 8 to which the free end of the pipe 9 is crimped, the crimping zone as well as the neighbouring parts of the pipe 9 and of the connecter 1 being completely trapped inside a single-part protective shell 10. This pipe is characterised in that its free end is crimped on to the end-fitting of the connecter via one or more compression lips 13, 14 projecting on the internal face of the protective shell 10, in the region of the zone of overlap between the pipe 9 and the end-fitting 8.

Description

Raccord de sécurité à sertissage direct, notamment pour usages médicaux.Safety fitting with direct crimping, especially for medical uses.

La présente invention concerne un tuyau souple à raccord de sécurité, notamment pour le transport de gaz à usages médicaux, dans lequel le raccord comporte un embout sur lequel l'extrémité libre du tuyau est sertie, la zone de sertissage ainsi que les parties voisines du tuyau et du raccord étant complétement emprisonnées dans une coquille protectrice monobloc. The present invention relates to a flexible hose with a safety connector, in particular for the transport of gases for medical purposes, in which the connector comprises a nozzle on which the free end of the hose is crimped, the crimping zone as well as the neighboring parts of pipe and fitting being completely trapped in a one-piece protective shell.

Sur de tels raccords de sécurité, le sertissage du tuyau se fait habituellement au moyen d'un collier de serrage amovible dont la coquille protectrice interdit l'accès au personnel médical,lequel n'est donc pas incité à effectuer lui-même le remplacement de tuyaux usagés ce qui, dans le cas où plusieurs tuyaux doivent être simultanément changés sur des raccords rattachés à des sources de gaz différents, supprime les risques d'une interversion accidentelle ou volontaire des tuyaux, qui pourrait être d'une conséquence catastrophique pour les patients. On such safety fittings, the crimping of the pipe is usually done by means of a removable hose clamp, the protective shell of which prevents access to medical personnel, who is therefore not encouraged to perform the replacement of himself. used hoses which, in the event that several hoses have to be changed simultaneously on fittings connected to different gas sources, eliminates the risks of accidental or voluntary reversal of the hoses, which could be of catastrophic consequence for patients .

Le remplacement des tuyaux usagés ne peut dès lors être réalisé que par une personne qualifiée, en général le fabricant des raccords, qui, après avoir cassé la coquille protectrice et enlevé le collier de serrage, retire le tuyau usagé du raccord, sertit sur celui-ci un tuyau neuf à l'aide du collier, avant de reformer autour de la zone de sertissage une nouvelle coquille protectrice présentant les mêmes caractéristiques que la précédente. The replacement of the used pipes can therefore only be carried out by a qualified person, in general the manufacturer of the fittings, who, after having broken the protective shell and removing the hose clamp, removes the used pipe from the fitting, crimped on it. ci a new pipe using the collar, before reforming around the crimping area a new protective shell having the same characteristics as the previous one.

La présente invention s'est fixé pour but de simplifier cette opération de remplacement de tuyaux usagés sur des raccords à coquille protectrice et, pour ce faire, elle propose un tuyau à raccord de sécurité du type spécifié en préambule qui se caractérise en ce que l'extrémité libre du tuyau est sertie sur l'embout du raccord par une ou plusieurs lèvre(s) de compression saillant sur la face intérieure de la coquille protectrice, au niveau de la zone de chevauchement entre le tuyau et l'embout du raccord. The purpose of the present invention is to simplify this operation of replacing used pipes on protective shell fittings and, to do this, it proposes a safety fitting pipe of the type specified in the preamble which is characterized in that the the free end of the pipe is crimped onto the end piece of the fitting by one or more compression lip (s) projecting from the inside face of the protective shell, at the level of the overlapping zone between the pipe and the end piece of the fitting.

La ou les lèvres de compression, avantageusement venues de matière avec le reste de la coquille,ont une hauteur suffisante pour, après l'assemblage de la coquille protectrice, s'enfoncer dans le tuyau souple et le coincer contre l'embout du raccord. The compression lip (s), advantageously formed integrally with the rest of the shell, have a sufficient height for, after assembly of the protective shell, sink into the flexible pipe and wedge it against the end of the fitting.

Il s'ensuit que la coquille protectrice, outre qu'elle constitue unesécurité interdisant les branchements erronés, remplit la fonction d'un organe de sertissage du tuyau sur le raccord et rend donc inutile l'utilisation des colliers de serrage traditionnels. La conséquence première en est une grande simplification de l'opération de remplacement des tuyaux usagés de par la suppression des étapes les plus longues d'enlèvement et de remise en place du collier de serrage. It follows that the protective shell, in addition to constituting a security preventing incorrect connections, fulfills the function of a crimping member of the pipe on the fitting and therefore makes the use of traditional clamps unnecessary. The first consequence is a great simplification of the operation of replacing the used pipes by eliminating the longest stages of removal and repositioning of the clamp.

Selon un mode de réalisation préféré de la présente invention, la coquille protectrice porte intérieurement deux lèvres de compression radiales qui sont disposées en vis-à-vis et qui, de préférence, couvrent chacune un peu moins d'une demi-circonférence du tuyau,pour que les efforts de compression se répartissent le plus uniformément possible sur ce dernier. According to a preferred embodiment of the present invention, the protective shell internally carries two radial compression lips which are arranged opposite and which, preferably, each cover a little less than half a circumference of the pipe, so that the compression forces are distributed as uniformly as possible on the latter.

Selon une autre caractéristique avantageuse de l'invention, la coquille protectrice est formée de deux demi-coquilles identiques en matière plastique, qui sont solidarisées l'une à l'autre, de préférence par un soudage ultrasonique, le long d'un plan de joint passant entre les deux lèvres de compression. According to another advantageous characteristic of the invention, the protective shell is formed from two identical plastic half-shells, which are joined to one another, preferably by ultrasonic welding, along a plane of joint passing between the two compression lips.

La coquille protectrice pourra en outre porter une couleur identifiant
le fluide que le tuyau à raccord doit véhiculer ou, en variante, dans le
cas où il s'agit d'un mélange binaire, les deux demi-coquilles pourront être teintées de couleurs différentes identifiant les deux composants du mélange.The protective shell may also bear an identifying color
the fluid that the connecting pipe must convey or, alternatively, in the
in the case of a binary mixture, the two half-shells may be tinted with different colors identifying the two components of the mixture.

Deux modes de réalisation de la présente invention vont maintenant être décrits plus en détails, mais uniquement à titre d'exemples non-limitatifs, en référence au dessin annexé dans lequel
la figure 1 est une vue en coupe longitudinale de l'extrémité libre d'un tuyau selon l'invention équipé d'un raccord de sécurité droit
la figure 2 est une vue en coupe effectuée selon la ligne Il-Il de la figure 1 et à échelle agrandie ; et
les figures 3 et 4 sont respectivement une vue en coupe longitudinale et une vue en plan de l'extrémité libre d'un tuyau selon l'invention équipé d'un raccord de sécurité coudé.Two embodiments of the present invention will now be described in more detail, but only by way of non-limiting examples, with reference to the accompanying drawing in which
Figure 1 is a longitudinal sectional view of the free end of a pipe according to the invention equipped with a straight safety connector
Figure 2 is a sectional view taken along the line II-II of Figure 1 and on an enlarged scale; and
Figures 3 and 4 are respectively a longitudinal sectional view and a plan view of the free end of a pipe according to the invention equipped with an elbow safety connector.

Le raccord de sécurité droit 1, visible sur la figure 1, présente une structure connue en soi et on s'attachera donc à n'en décrire que les caractéristiques essentielles. The right safety connector 1, visible in Figure 1, has a structure known per se and we will therefore endeavor to describe only the essential characteristics.

Comme on peut le voir, ce raccord 1 comprend un porte-griffes creux 2 monté à rotation libre autour d'un corps cylindrique central 3 percé, tout le long de son axe longitudinal, d'un canal non représenté. As can be seen, this connector 1 comprises a hollow claw holder 2 mounted for free rotation around a central cylindrical body 3 pierced, all along its longitudinal axis, with a channel not shown.

Plus précisément, le porte-griffes 2, muni sur sa face libre de griffes d'accouplement 5, s'appuie du côté de ces dernières sur un disque 6 venu de matière avec le corps 3 et est immobilisé en translation, de l'autre côté, par une rondelle fendue saillante 7, qui est encliquetée autour de ce dernier. More specifically, the claw-holder 2, provided on its free face with coupling claws 5, bears on the side of the latter on a disc 6 made integrally with the body 3 and is immobilized in translation, on the other side, by a projecting split washer 7, which is snapped around the latter.

Quant au corps central 3, il comprend, à l'intérieur du porte-griffes 2, un mince conduit de connexion 3a et se prolonge, de l'autre côté, sur la face extérieure 2a du porte-griffes , par un embout tubulaire 8 sur lequel l'extrémité libre d'un tuyau souple 9 est sertie au moyen d'une coquille monobloc en matière plastique 10 qui, outre ladite extrémité libre du tuyau, enveloppe également toute la partie du raccord 1 extérieure au portegriffes 2. As for the central body 3, it comprises, inside the claw-holder 2, a thin connection conduit 3a and is extended, on the other side, on the outer face 2a of the claw-holder, by a tubular end piece 8 on which the free end of a flexible pipe 9 is crimped by means of a one-piece plastic shell 10 which, in addition to said free end of the pipe, also envelops the entire part of the connector 1 external to the clip holder 2.

Comme on peut le voir sur la figure 1, la coquille 10 comprend un premier tronçon tubulaire 11 qui enserre la partie saillante du corps 3 jusqu'à venir en contact glissant avec la face extérieure 2a du porte-griffes 2, et un second tronçon tubulaire 12 de plus petit diamètre, qui s'applique étroitement tout autour du tuyau 9. Au niveau de la zone de transition entre ces deux tronçons tubulaires 11, 12, la coquille 10 porte intérieurement deux lèvres ou mâchoires de compression saillantes 13, 14, qui s'étendent en vis-à-vis dans un même plan perpendiculaire à l'axe de l'embout 8 et sont d'une hauteur suffisante pour s'enfoncer dans le tuyau souple 9 et le coincer contre l'embout 8 du raccord 1. As can be seen in FIG. 1, the shell 10 comprises a first tubular section 11 which encloses the projecting part of the body 3 until it comes into sliding contact with the outer face 2a of the claw-holder 2, and a second tubular section 12 of smaller diameter, which is applied tightly all around the pipe 9. At the transition zone between these two tubular sections 11, 12, the shell 10 internally carries two projecting lips or compression jaws 13, 14, which extend vis-à-vis in the same plane perpendicular to the axis of the end piece 8 and are of sufficient height to sink into the flexible pipe 9 and wedge it against the end piece 8 of the connector 1 .

La figure 2 montre clairement que la coquille 10 est en fait formée de deux demi-coquilles identiques 10a et 10b, qui sont mutuellement solidarisées le long d'un plan de joint diamètral et portent chacune une lèvre de compression respective 13 ou 14. Par ailleurs, les lèvres de compression, qui ont une forme en arc de cercle, couvrent respectivement un peu moins d'une demi-circonférence du tuyau 9, ctest-à-dire environ 140#1500, et ont des positions symétriques par rapport au plan de joint des demi-coquilles 10a et 10b. FIG. 2 clearly shows that the shell 10 is in fact formed by two identical half-shells 10a and 10b, which are mutually secured along a diametrical joint plane and each carry a respective compression lip 13 or 14. Furthermore , the compression lips, which have an arc-shaped shape, respectively cover a little less than a half-circumference of the pipe 9, that is to say about 140 # 1500, and have positions symmetrical with respect to the plane of joint of the half-shells 10a and 10b.

Comme cela va de soi, les lèvres de compression 13, 14 sont venues de matière avec les demi-coquilles respectives et seront, pour ce faire, produites directement lors du moulage de ces dernières. As it goes without saying, the compression lips 13, 14 have come integrally with the respective half-shells and will be, to do this, produced directly during the molding of the latter.

On voit donc que la coquille 10, qui ordinairement constitue un élément de sécurité contre les tentatives dangereuses de remplacement des tuyaux par des personnes non qualifiées, joue simultanément le rôle, dans la présente invention, de l'organe de sertissage du tuyau 9 sur l'embout 8 du raccord 1. It can therefore be seen that the shell 10, which ordinarily constitutes a security element against dangerous attempts to replace the pipes by unqualified persons, simultaneously plays the role, in the present invention, of the pipe crimping member 9 on the end 8 of connector 1.

Dès lors l'opération de remplacement des tuyaux usagés est grandement simplifiée, puisque le tuyau 9, préalablement enfilé sur l'embout 8, est auto matiquement serti sur ce dernier, grâce à la présence des lèvres de compression, après l'assemblage mutuel des deux demi-coquilles 10a et 10b le long de leur plan de joint, assemblage qui sera de préférence réalisé par un soudage ultrasonique. Therefore the operation of replacing the used pipes is greatly simplified, since the pipe 9, previously threaded on the end piece 8, is automatically crimped onto the latter, thanks to the presence of the compression lips, after the mutual assembly of the two half-shells 10a and 10b along their joint plane, assembly which will preferably be carried out by ultrasonic welding.

Dans le second mode de réalisation du tuyau à raccord de sécurité conforme à l'invention et illustré par les figures 3 et 4, le raccord 1' est un raccord rotatif coudé dans lequel la partie du corps , saillant à l'ex- térieur du porte-griffes 2', est constituée par une pièce cylindrique fermée
15 de grande longueur et l'embout tubulaire 8' vient se visser à angle droit dans un perçage taraudé de la paroi latérale de cette pièce cylindrique 15.In the second embodiment of the hose with safety connector according to the invention and illustrated by FIGS. 3 and 4, the connector 1 ′ is a bent rotary connector in which the part of the body, projecting outside the claw holder 2 ', consists of a closed cylindrical piece
15 of great length and the tubular end piece 8 'is screwed at a right angle into a threaded bore in the side wall of this cylindrical part 15.

Une collerette à six pans 16 est d'ailleurs prévue sur l'embout 8' -pour faciliter ce vissage par utilisation d'une clé plate.A hexagonal flange 16 is also provided on the nozzle 8 '- to facilitate this screwing by using a flat wrench.

La coquille 10' présente une forme correspondante définie par un premier tronçon sensiblement tubulaire 17, qui s'étend jusqu'à la pièce cylindrique 15 en enveloppant l'extrémité libre du tuyau 9' et l'embout 8', et par une calotte de section circulaire 18 qui présente un axe longitudinal perpendiculaire à celui du premier tronçon 17, pour pouvoir envelopper complètement la pièce cylindrique 15 tout en venant en contact glissant avec la face extérieure du porte-griffes 2. The shell 10 'has a corresponding shape defined by a first substantially tubular section 17, which extends to the cylindrical part 15 by enveloping the free end of the pipe 9' and the end piece 8 ', and by a cap of circular section 18 which has a longitudinal axis perpendicular to that of the first section 17, in order to be able to completely envelop the cylindrical part 15 while coming into sliding contact with the external face of the claw-holder 2.

Dans ce second mode de réalisation de l'invention, les deux lèvres de compression 13', 14' sont formées à l'intérieur du premier tronçon tubulaire
17 de la coquille 10', au niveau de la zone de chevauchement entre l'extrémité libre du tuyau 9'et l'embout 8'du raccord 1. Pour le reste, ce second mode de réalisation de l'invention est en tous points identique au premier, notamment en ce qui concerne le dimensionnement et le positionnement mutuel des lèvres de compression 13', 14', le mode de formation de celles-ci et la manière dont est réalisée la coquille 10' à partir de deux demi-coquilles 10'a, 10'b.In this second embodiment of the invention, the two compression lips 13 ', 14' are formed inside the first tubular section
17 of the shell 10 ′, at the level of the overlap zone between the free end of the pipe 9 ′ and the end piece 8 ′ of the connector 1. For the rest, this second embodiment of the invention is in all respects identical to the first, in particular as regards the dimensioning and the mutual positioning of the compression lips 13 ′, 14 ′, the mode of formation of these and the manner in which the shell 10 ′ is produced from two half-shells 10'a, 10'b.

Pour être complet, on précisera encore que la coquille 10 ou 10' du raccord selon l'invention sera colorée d'une teinte identifiant le gaz destiné à être transporté par le tuyau 9 ou 9' ou que, dans le cas où ce gaz est un mélange binaire, les deux demi-coquilles qui la constituent seront colorées différemment pour permettre l'identification des deux composants du mélange gazeux.  To be complete, it will also be specified that the shell 10 or 10 ′ of the connector according to the invention will be colored with a shade identifying the gas intended to be transported by the pipe 9 or 9 ′ or that, in the case where this gas is a binary mixture, the two half-shells which constitute it will be colored differently to allow the identification of the two components of the gas mixture.
