Abstract

Device for controlling a flow rate, in particular for medical or dental use, intended to be fitted on a flexible tube for dispensing a liquid, for example a medical liquid or a dental fluid, without any interruption or perforation of the said tube, characterised in that it is made up of two parts (1, 4) through which the tube (16) for dispensing liquid can pass. The parts (1, 4) can be moved relative to one another and in each case have a point for securing the tube (16) in such a way that, during the movements relative to one another, the tube is subjected to a folding to a greater or lesser extent, thereby leaving a passage for fluid which varies as a function of the folding to which it is subjected.

Description

La présente invention a pour objet un dispositif régulateur de débit, en particulier à usage médical ou dentaire, destiné à être monté sur un tube souple de distribution d'un liquide, par exemple liquide médical ou fluide dentaire, sans interruption ni perforation dudit tube. The present invention relates to a flow regulating device, in particular for medical or dental use, intended to be mounted on a flexible tube for dispensing a liquid, for example medical liquid or dental fluid, without interrupting or perforating said tube.

L'invention a également pour objet les lignes de distribution de liquide équipées d'un tel régulateur. The invention also relates to liquid distribution lines equipped with such a regulator.

Dans ce qui suit, on s'attachera à décrire un tel dispositif de régulation dans le cas d'applications médicales ou dentaires. In what follows, we will endeavor to describe such a regulation device in the case of medical or dental applications.

Pour le domaine médical, un tel régulateur peut être utilisé sur une ligne de perfusion ou de transfusion sanguine. Dans le domaine dentaire, il peut être monté en régulateur de débit d'arrosage (spray) des instruments dentaires en cours de travail. For the medical field, such a regulator can be used on an infusion or blood transfusion line. In the dental field, it can be fitted with a spray flow regulator for dental instruments during work.

On comprendra néanmoins que ce régulateur n'est nullement limité à ces applications spécifiques. It will nevertheless be understood that this regulator is in no way limited to these specific applications.

Parmi les dispositifs connus, on rencontre d'une part des régulateurs de précision dont le coût est trop élevé pour les applications courantes, et d'autre part des régulateurs plus économiques, en particulier de deux types. Among the known devices, there are on the one hand precision regulators whose cost is too high for current applications, and on the other hand more economical regulators, in particular of two types.

Le premier type consiste en une plaquette généralement en alliage léger pourvue de perçages ou découpages dans lesquels le tube est introduit. La régulation du débit est obtenue par pliage de ladite plaquette, provoquant le pliage plus ou moins important du tube, qui laisse ainsi plus ou moins passer le liquide. The first type consists of a plate generally made of light alloy provided with holes or cutouts in which the tube is introduced. The regulation of the flow rate is obtained by folding of said plate, causing the tube to bend more or less, which thus lets the liquid pass more or less.

Ce dispositif n'assure pas une stabilité suffisante du débit, car d'une part la plaquette tend à reprendre son état initial et d'autre part elle est sujette à déformation à la moindre action mécanique sur le tube. This device does not ensure sufficient stability of the flow rate, because on the one hand the plate tends to return to its initial state and on the other hand it is subject to deformation at the slightest mechanical action on the tube.

L'autre type consiste en une gouttière dans laquelle se déplace une roulette qui selon sa position comprime plus ou moins le tube. The other type consists of a gutter in which a wheel moves which, depending on its position, more or less compresses the tube.

Ce type de dispositif présente deux inconvénients - la position de réglage n'est pas verrouillée mécaniquement d'où un risque de déréglage ; - l'arrêt complet du débit est souvent délicat à obtenir car certains tubes sont difficiles à comprimer complètement. This type of device has two drawbacks - the adjustment position is not mechanically locked, hence a risk of adjustment; - complete stopping of the flow is often difficult to obtain because some tubes are difficult to compress completely.

L'invention à pour objet de remédier à ces inconvénients des dispositifs de l'art antérieur.  The object of the invention is to remedy these drawbacks of the devices of the prior art.

Conformément à l'invention, on propose en effet un dispositif régulateur de débit, en particulier à usage médical ou dentaire, destiné à être monté sur un tube souple de distribution d'un liquide, par exemple liquide médical ou fluide dentaire, sans interruption ni perforation dudit tube, caractérisé en ce qu'il est composé de deux pièces au travers desquelles peut passer le tube de distribution de liquide, mobiles l'une par rapport à l'autre et possédant chacune un point de fixation du tube, de telle manière que lors des mouvements relatifs de l'une par rapport à l'autre le tube subisse un pliage plus ou moins important laissant ainsi un passage de fluide variant en fonction du pliage qu'il subit. In accordance with the invention, a flow regulating device is proposed, in particular for medical or dental use, intended to be mounted on a flexible tube for dispensing a liquid, for example medical liquid or dental fluid, without interruption or perforation of said tube, characterized in that it is composed of two parts through which the liquid distribution tube can pass, movable relative to each other and each having a point of attachment of the tube, so that during relative movements of one with respect to the other the tube undergoes a more or less significant bending thus leaving a passage of fluid varying according to the bending which it undergoes.

Le déplacement relatif d'une pièce par rapport à l'autre peut être obtenu soit par une action manuelle soit par l'action d'un élément extérieur tel qu'un fluide sous pression. The relative displacement of a part with respect to the other can be obtained either by manual action or by the action of an external element such as a pressurized fluid.

On comprendra mieux l'invention à l'aide de la description faite ci-après d'un certain nombre de modes non limitatifs de mise en oeuvre, en référence aux dessins annexés dans lesquels - la figure 1 est une vue en coupe longitudinale d'un dispositif conforme à l'invention, certains éléments étant représentés partiellement agrandis pour une meilleure compréhension - la figure 1A est une vue de dessus de la figure 1 - la figure 1B est une coupe selon A-A de la figure 1 - les figures 2, 3 et 4 sont des variantes de mise en oeuvre du dispositif de la figure 1, en coupe longitudinale. The invention will be better understood with the aid of the description given below of a number of nonlimiting modes of implementation, with reference to the appended drawings in which - FIG. 1 is a view in longitudinal section of a device according to the invention, certain elements being shown partially enlarged for a better understanding - FIG. 1A is a top view of FIG. 1 - FIG. 1B is a section along AA of FIG. 1 - FIGS. 2, 3 and 4 are alternative embodiments of the device of FIG. 1, in longitudinal section.

La figure 1 représente un mode de réalisation de l'objet de l'invention composé d'un corps t1) présentant en son intérieur une chambre t2) dans laquelle débouche un orifice t3) qui reçoit le tube t16), ledit tube étant maintenu solidaire du corps il), et d'une pièce coulissante t4) percée longitudinalement pour permettre le passage du tube. L'extrémité t5) de la pièce t4) pénètre dans la chambre t2) qu'elle ferme et possède un orifice t6) dans lequel le tube est maintenu solidairement. FIG. 1 represents an embodiment of the object of the invention composed of a body t1) having inside a chamber t2) into which opens an orifice t3) which receives the tube t16), said tube being held integral of the body il), and of a sliding part t4) pierced longitudinally to allow the passage of the tube. The end t5) of the part t4) enters the chamber t2) which it closes and has an orifice t6) in which the tube is held integrally.

On comprendra aisément que suivant la position de la pièce coulissante (4), le tube sera soit droit - on obtiendra alors le débit maximum - soit plié, ce qui provoque une réduction du débit et ce jusqu'au stade où la pliure provoque la fermeture complète du tube. It will easily be understood that, depending on the position of the sliding part (4), the tube will either be straight - the maximum flow will then be obtained - or bent, which causes a reduction in flow and this up to the stage where the fold causes closure complete of the tube.

En complément, les pièces (1) et t4) sont pourvues chacune d'une fente longitudinale, respectivement t7) et t8), afin de permettre l'introduction radiale du tube afin d'éviter la contrainte d'introduction du tube par une de ses extrémités qui en général sont pourvues d'embouts de raccordement ou de perfusion. Judicieusement la largeur de ces fentes (7) et (8) sera légèrement inférieure au diamètre du tube afin que ce dernier ne puisse ressortir naturellement. In addition, the parts (1) and t4) are each provided with a longitudinal slot, respectively t7) and t8), in order to allow the radial introduction of the tube in order to avoid the constraint of introduction of the tube by one of its ends which in general are provided with connection or infusion tips. Judiciously the width of these slots (7) and (8) will be slightly less than the diameter of the tube so that the latter cannot come out naturally.

Pour faciliter la manipulation les deux fentes t7) et (8) sont maintenues alignées grâce à un système d'indexation réalisé par exemple par un ergot (9) au moins qui coulisse dans une fente (lO) de la pièce (1). To facilitate handling, the two slots t7) and (8) are kept aligned thanks to an indexing system produced for example by at least one lug (9) which slides in a slot (10) of the part (1).

Dans ce mode de réalisation, la pièce coulissante (4) est pourvue, sur au moins une partie de sa longueur d'engagement, de formes du type cannelures circulaires (ll) réalisées dans un plan perpendiculaire à l'axe de déplacement de (4).  In this embodiment, the sliding part (4) is provided, over at least part of its length of engagement, with shapes of the circular groove type (ll) produced in a plane perpendicular to the axis of movement of (4 ).

Lesdites cannelures (il) entrent en combinaison avec au moins une forme cannelée (12) de la pièce (1), qui est pourvue de fentes longitudinales (13), dont une peut être judicieusement cannelée avec la fente (7), de façon à permettre une déformation élastique de la pièce (l).  Said grooves (it) come in combination with at least one grooved shape (12) of the part (1), which is provided with longitudinal slots (13), one of which can be suitably grooved with the slot (7), so as to allow elastic deformation of the part (l).

On obtient ainsi un dispositif d'encliquetage à position variable.A variable position latching device is thus obtained.

Enfin, les pièces (l) et t4) dans leurs orifices respectifs (3) et t6), sont pourvues d'une forme, respectivement (14) et (15) légèrement saillante dans l'intérieur. Les orifices respectivement (3) et (6) assurent un léger serrage du tube qui est ainsi rendu solidaire respectivement de (l) et (4). Finally, the parts (l) and t4) in their respective orifices (3) and t6), are provided with a shape, respectively (14) and (15) slightly projecting in the interior. The orifices respectively (3) and (6) ensure a slight tightening of the tube which is thus made integral respectively with (l) and (4).

La figure 2 représente un autre mode de réalisation dans lequel les cannelures sont remplacées par un ensemble filetage-taraudage (2'). FIG. 2 represents another embodiment in which the splines are replaced by a thread-tapping assembly (2 ′).

Le tube est d'une part calé dans la pièce (1') et maintenu dans la pièce (3') par un manchon de serrage t4') permettant la rotation de la pièce (3') sans torsion du tube. The tube is on the one hand wedged in the part (1 ') and held in the part (3') by a clamping sleeve t4 ') allowing the rotation of the part (3') without twisting the tube.

La figure 3 représente un mode de réalisation dans lequel le dispositif se compose d'un corps (1") en une ou plusieurs pièces comprenant un piston t2") poussé par un ressort (3"). La position du piston est réglée par un système vis-écrou. FIG. 3 represents an embodiment in which the device consists of a body (1 ") in one or more parts comprising a piston t2") pushed by a spring (3 "). The position of the piston is adjusted by a screw-nut system.

La solution représentée se comporte en vanne normalement fermée, c'est-à-dire qu'en l'absence de l'action de la vis, le piston poussé par le ressort ferme le tube. Il est évident que la réalisation inverse répond aux mêmes caractéristiques. The solution shown behaves as a normally closed valve, that is to say that in the absence of the action of the screw, the piston pushed by the spring closes the tube. It is obvious that the reverse realization meets the same characteristics.

Enfin, la figure 4 représente un mode de réalisation qui permet de commander la position du piston par un agent fluide sous pression, lequel fluide remplace la vis de la figure 2. Le fluide est amené par une conduite (17). Finally, FIG. 4 represents an embodiment which makes it possible to control the position of the piston by a fluid agent under pressure, which fluid replaces the screw of FIG. 2. The fluid is supplied by a pipe (17).

Ce dispositif est particulièrement bien adapté aux applications dentaires, pour lesquelles la commande fluide peut être soit l'air de commande de pilotage des moteurs à air ou turbine, soit l'air dit de refroidissement moteur, soit encore l'eau de spray. On obtient avec ce dispositif une ligne de distribution qui entre en fonction, soit uniquement lorsque l'appareil dentaire (par exemple le racleur) est en marche, soit uniquement lorsque l'eau de spray est commandée.  This device is particularly well suited to dental applications, for which the fluid control can be either the air for controlling the piloting of air motors or turbines, or the so-called engine cooling air, or even spray water. With this device, a distribution line is obtained which comes into operation, either only when the dental appliance (for example the scraper) is running, or only when the spray water is controlled.
