Abstract
Description
La présente invention se réfère à un raccord construit en résine synthétique transparente destiné à répartir un flux unique de liquide en plusieurs flux égaux. Ce raccord est particulièrement utile dans l'administration d'injections multiples au cours d'une opération unique ou pour répartir en parties égales le contenu d'un seul flacon dans différents flacons. The present invention refers to a connector constructed of transparent synthetic resin intended to distribute a single flow of liquid into several equal flows. This connector is particularly useful in the administration of multiple injections in a single operation or to distribute the contents of a single vial in equal parts in different vials.
L'utilisation d'un tel raccord se situe en général dans le champ des traitements esthétiques ou médicamentaux. The use of such a fitting is generally situated in the field of aesthetic or medicinal treatments.
On connait des raccords interposés entre une seringue et une multiplicité d'aiguilles. Ces raccords sont fabriqués par exemple en métal inoxydable ou en PVC opaque pour l'usage médical. There are known connections interposed between a syringe and a multiplicity of needles. These fittings are made, for example, of stainless metal or opaque PVC for medical use.
Ces deux réalisations présentent des inconvénients et en particulier la réalisation métallique est de lavage difficile tandis que la réalisation en PVC qui ne présente pas cet inconvénient du fait qu'elle est jetable et soudée d'une façon grossière par fusion avec un bord arrondi qui en augmente l'encombrement et en diminue la maniabilité et qui de plus au point de vue esthétique à l'aspect d'un objet de mauvaise qualité
En outre ces deux réalisations présentent l'inconvénient de nécessiter un raccord opaque.These two embodiments have drawbacks, and in particular the metallic construction is difficult to wash, while the PVC construction which does not have this drawback because it is disposable and coarsely welded by fusion with a rounded edge which increases the overall dimensions and reduces its maneuverability and which, from an aesthetic point of view, looks like a poor quality object
In addition, these two embodiments have the drawback of requiring an opaque connection.
D'autres types de raccords réalisés avec différentes résines synthétiques sont limités dans leur emploi à l'anesthésie locale et même dans ce cas le nombre de porteaiguilles est limité à 4. Other types of fittings made with different synthetic resins are limited in their use to local anesthesia and even in this case the number of needle holders is limited to 4.
Ces inconvénients et cet usage limité sont surmontés par le raccord, objet de la présente invention, lequel selon les figures jointes est constitué de deux éléments, un supérieur (1) et un inférieur (2) délimitant un espace (6) pour la distribution du liquide, caractérisé par sa réalisation en résine synthétique transparente dans laquelle les parties (1) et (2) sont soudées par la technique des ultra-sons. These drawbacks and this limited use are overcome by the connector, object of the present invention, which according to the attached figures consists of two elements, an upper (1) and a lower (2) delimiting a space (6) for the distribution of the liquid, characterized by its realization in transparent synthetic resin in which the parts (1) and (2) are welded by the technique of ultrasound.
Ces caractéristiques et avantages, ainsi que d'autres, du raccord selon la présente invention sont mis en évidence par la description suivante et les figures qui l'illustrent, de modes de réalisation préférentiels mais non limitatifs. These characteristics and advantages, as well as others, of the connector according to the present invention are highlighted by the following description and the figures which illustrate it, of preferred but nonlimiting embodiments.
Les figures 1, 2 et 3 présentent une réalisation de forme circulaire ; la figure 1 et la figure 2 en particulier représentent la partie inférieure (2), vue en plan tandis que la figure 3 représente le raccord vu en coupe. Figures 1, 2 and 3 show an embodiment of circular shape; Figure 1 and Figure 2 in particular show the lower part (2), in plan view while Figure 3 shows the connector seen in section.
Une représentation analogue se référant à une réalisation rectangulaire est illustrée par les figures 4, 5 et 6, les figures 7 et 8 sont les représentations en pespective d'une réalisation circulaire et d'une réalisation rectangulaire. A similar representation referring to a rectangular embodiment is illustrated by FIGS. 4, 5 and 6, FIGS. 7 and 8 are the representations in perspective of a circular embodiment and of a rectangular embodiment.
La présente invention pourrait être encore réalisée par un raccord de forme carrée. The present invention could also be achieved by a square-shaped connector.
Comme il résulte clairement des figures, le raccord selon l'invention est constitué de deux parties (1) et (2) qui en forment les parties supérieure et inférieure. As is clear from the figures, the connector according to the invention consists of two parts (1) and (2) which form the upper and lower parts.
Ces deux pièces coïncident parfaitement et sont soudées périphériquement par la technique des ultrasons qui procure une structure régulière et une esthétique optimale. These two parts coincide perfectly and are welded peripherally by the ultrasound technique which provides a regular structure and optimal aesthetics.
Un autre mode de réalisation peut être obtenu en scellant les deux éléments supérieur et inférieur au moyen d'un adhésif ou d'une colle adéquate. Another embodiment can be obtained by sealing the two upper and lower elements with an adhesive or suitable glue.
Dans la partie supérieure (1) est ménagée un orifice d'entrée (7) auquel correspond sur le côté extérieur un embout (3) auquel peut être fixée une seringue, un flacon ou une tubulure d'alimentation. In the upper part (1) is provided an inlet (7) which corresponds on the outside a tip (3) to which can be attached a syringe, a vial or a supply tube.
Dans la partie inférieure (2) sont ménagés des orifices de sortie (8) auxquels correspondent sur le côté extérieur des montures coniques (5) auxquelles on peut adapter - des aiguilles à injecter Si on désire procéder directement à une injection - des tubes diffuseurs aboutissant dans des flacons Si l'opération à effectuer consiste simplement à répartir un liquide. In the lower part (2) are provided outlet orifices (8) to which correspond on the outer side of the conical mounts (5) to which can be adapted - needles to be injected If one wishes to proceed directly to an injection - diffusing tubes terminating in bottles If the operation to be carried out consists simply in distributing a liquid.
- des tubes de raccord auxquels peuvent être adaptés des aiguilles si l'on désire effectuer une injection dans une zone de dimensions différentes de celles de l'instrument.- connection tubes to which needles can be adapted if one wishes to carry out an injection in an area of dimensions different from those of the instrument.
Le nombre des orifices de sortie (8) quelle que soit la forme de réalisation peut varier de deux à dix neuf. Les deux parties (1) et (2) délimitent un espace vide (6) pour la distribution du liquide de l'embout (3) d'entrée aux orifices de sortie (8). Cet espace vide peut être constitué par une chambre unique ou par des canalisations (4) aménagées dans l'épaisseur de la résine de la partie supérieure (l) ou inférieure (2) de manière que chacune de ces canalisations mette en communication l'orifice d'entrée avec un ou plusieurs orifices de sortie. The number of outlet ports (8) regardless of the embodiment can vary from two to nineteen. The two parts (1) and (2) define an empty space (6) for the distribution of the liquid from the inlet nozzle (3) to the outlet orifices (8). This empty space can be constituted by a single chamber or by pipes (4) arranged in the thickness of the resin of the upper (l) or lower (2) part so that each of these pipes connects the orifice. inlet with one or more outlet openings.
Les orifices d'entrée et de sortie sont calibrés de façon à permettre que le flux d'entrée soit réparti d'une manière homogène entre les orifices de sortie en y laissant passer une quantité égale de liquide. The inlet and outlet ports are calibrated to allow the inlet flow to be distributed evenly between the outlet ports, allowing an equal amount of liquid to pass through.
Les montures coniques (5) peuvent avoir une conicité de 6% selon le standard américain LUER ou 10% selon les normes
UNI.The conical frames (5) can have a taper of 6% according to the American standard LUER or 10% according to the standards
UNITED.
Le raccord selon l'invention est réalisé en résine synthétique transparente, de préférence en copolymère acrylonitrile-polystyrol. The connector according to the invention is made of transparent synthetic resin, preferably of acrylonitrile-polystyrol copolymer.
Cette dernière résine est suffisamment rigide pour éviter des déformations durant les manipulations et en outre étant transparente permet le contrôle visuel et instrumental du liquide. Le contrôle du liquide est très important pour appr- cier d'éventuelles détériorations de celui-ci telles qu'altérations de couleur ou l'apparition de troubles; en outre on peut observer la présence éventuelle de corps étrangers ou de bulles d'air qui peuvent être d'un grand péril en cours de manipulation. The latter resin is rigid enough to avoid deformation during handling and, furthermore, being transparent allows visual and instrumental control of the liquid. The control of the liquid is very important in order to assess any deterioration thereof such as color changes or the appearance of disorders; in addition one can observe the possible presence of foreign bodies or air bubbles which can be of great danger during handling.
En pratique médicale, il arrive fréquemment que l'on doive effectuer des injections multiples sur une zone plus ou moins étendue et que l'opérateur doive effectuer de nombreuses injections successives très désagréables pour le patient. In medical practice, it frequently happens that multiple injections have to be made over a more or less large area and that the operator has to perform numerous successive injections which are very unpleasant for the patient.
Le raccord selon l'invention, interposé entre la seringue et de nombreuses aiguilles, permet d'effectuer simultanément de multiples injections évitant la répétition d'injections uniques. The connector according to the invention, interposed between the syringe and many needles, makes it possible to simultaneously perform multiple injections avoiding the repetition of single injections.
Le dit raccord présente une grande utilité dans de multiples causes d'intervention comme par exemple en mésothérapie, chiropraxie, injections sous-cutanées, arthropathies, cellulites, stimulations de la croissance musculaire, médecine sportive, chirurgie esthétique, traumatologie et orthopédie. Said fitting is of great use in multiple causes of intervention such as, for example, mesotherapy, chiropractic, subcutaneous injections, arthropathies, cellulites, stimulation of muscle growth, sports medicine, cosmetic surgery, trauma and orthopedics.
