Description

DISPOSITIF DE RECONSTITUTION NOTAMMENT POUR LE MELANGE DE SUBSTANCES DANS LE DOMAINE MEDICAL RECONSTRUCTION DEVICE, PARTICULARLY FOR MIXING SUBSTANCES IN THE MEDICAL FIELD
La présente invention a trait au mélange d'une substance avec une autre, notamment dans le domaine médical en vue par exemple de la reconstitution d'un médicament au moyen d'un diluant.The present invention relates to the mixing of one substance with another, in particular in the medical field with a view for example to the reconstitution of a medicament by means of a diluent.
Plus précisément, l'invention vise le dispositif, dénommé communément dispositif de reconstitution, destiné à opérer un tel mélange.More specifically, the invention relates to the device, commonly called reconstitution device, intended to operate such a mixture.
Divers médicaments devant être injectés par voie intraveineuse à un patient doivent être auparavant mélangés à un diluant qui peut être par exemple une solution de dextrose, une solution saline ou même de l'eau.Various drugs to be injected intravenously into a patient must first be mixed with a diluent which can be for example a dextrose solution, a saline solution or even water.
Bon nombre de ces médicaments sont stockés dans des fioles en verre sous forme de poudre ou à l'état liquide.Many of these drugs are stored in glass vials in powder or liquid form.
Au moment de leur administration, ces médicaments doivent être mélangés à un diluant contenu dans une poche souple munie à cet effet d'une tubulure d'injection comportant un embout en un matériau, tel que du latex par exemple, susceptible d'être percé par une aiguille, le passage formé par cette dernière se refermant de lui-même dès le retrait de l'aiguille.At the time of their administration, these medicinal products must be mixed with a diluent contained in a flexible bag provided for this purpose with injection tubing comprising an end piece made of a material, such as latex for example, capable of being pierced by a needle, the passage formed by the latter closing itself upon withdrawal of the needle.
Habituellement, la communication entre la fiole de médicament et la poche souple est assurée à l'aide d'un dispositif de reconstitution constitué d'une aiguille creuse pointue à ses deux extrémités et faisant saillie dans deux douilles cylindriques ouvertes disposées tête-bêche et conformées pour recevoir, l'une, l'embouchure de la fiole avec son bouchon en latex par exemple et, l'autre, l'embout de la tubulure d'injection de ia poche souple. Au moment de l'utilisation du médicament, le dispositif de reconstitution est sorti de son emballage stérile, l'aiguille, côté fiole, du dispositif est engagée à fond au travers du bouchon, puis l'autre aiguille est introduite également à fond dans l'embout de la poche souple, la communication entre cette dernière et la fiole étant ainsi assurée via le dispositif de reconstitution.Usually, the communication between the drug vial and the flexible bag is ensured using a reconstitution device consisting of a hollow needle pointed at its two ends and projecting into two open cylindrical sockets arranged head to tail and shaped to receive, one, the mouth of the vial with its latex stopper for example and, the other, the tip of the injection tubing of the flexible bag. When the drug is used, the reconstitution device is removed from its sterile packaging, the needle, vial side, of the device is fully engaged through the stopper, then the other needle is also fully inserted into the 'tip of the flexible bag, communication between the latter and the vial being thus ensured via the reconstitution device.
Un tel système présente l'inconvénient de la nécessité de stocker séparément les poches souples, les fioles et les dispositifs de reconstitution.Such a system has the drawback of the need to store flexible bags, vials and reconstitution devices separately.
Le but de la présente invention est de simplifier ce système et de le rendre plus économique en associant dispositif de reconstitution et poche souple dès la fabrication de cette dernière par pré-positionnement dudit dispositif, et en conditionnant l'ensemble dispositif + poche dans un emballage stérile unique.The aim of the present invention is to simplify this system and make it more economical by combining a reconstitution device and a flexible pouch as soon as the latter is manufactured by pre-positioning said device, and by packaging the device + pouch assembly in a package. single sterile.
A cet effet, l'invention a pour objet un dispositif de reconstitution notamment pour le mélange de substances dans le domaine médical, du type comprenant une aiguille creuse, pointue à ses deux extrémités et fixée sur un support définissant deux douilles coaxiales enveloppant chaque extrémité de l'aiguille et chargée de recevoir, l'une, l'embouchure à bouchon d'une fiole et, l'autre, l'embout d'une tubulure d'injection d'une poche souple, en sorte, par perforation desdits bouchon et embout, de mettre en communication la fiole et la poche souple via ladite aiguille, caractérisé en ce que ladite douille, côté poche souple, est dimensionnée et agencée pour s'engager sur l'embout en une première position stable dans laquelle le dispositif est solidarisé de la poche sans que l'aiguille soit en contact avec l'embout et en ce que ladite douille est montée coulissante sur l'embout en sorte de passer, par un simple enfoncement du dispositif sur l'embout, de ladite première position en une seconde position, stable, correspondant au transpercement de l'embout par l'aiguille.To this end, the subject of the invention is a reconstitution device in particular for mixing substances in the medical field, of the type comprising a hollow needle, pointed at its two ends and fixed on a support defining two coaxial sockets enveloping each end of the needle and responsible for receiving, one, the mouthpiece with a stopper of a vial and, the other, the end piece of an injection tube of a flexible bag, so, by perforation of said stopper and tip, to put the vial and the flexible bag into communication via said needle, characterized in that said socket, on the flexible pocket side, is dimensioned and arranged to engage on the tip in a first stable position in which the device is secured to the pocket without the needle being in contact with the nozzle and in that said sleeve is slidably mounted on the nozzle so as to pass, by a simple depression of the device on the nozzle, said first position in a second, stable position, corresponding to the piercing of the nozzle by the needle.
Il est ainsi possible de stocker notamment sous emballage stérile, l'association poche souple-dispositif de reconstitution qui forme un ensemble unitaire prêt à être utilisé puisque le dispositif de reconstitution est déjà en place, sans toutefois que l'aiguille soit insérée dans l'embout de la poche dont le contenu peut demeurer ainsi totalement isolé de l'extérieur. Un seul ensemble est ainsi à gérer, à stocker et à manipuler.It is thus possible to store in particular in sterile packaging, the combination of flexible pouch and reconstitution device which forms a unitary unit ready to be used since the reconstitution device is already in place, without however the needle being inserted into the pocket end of which the content can thus remain completely isolated from the outside. A single set is thus to manage, store and handle.
Au moment de l'utilisation de la poche, il suffit d'enlever l'emballage stérile s'il y en a un, d'engager le bouchon d'une fiole dans la douille du dispositif afin de transpercer le bouchon, puis d'enfoncer l'ensemble fiole- dispositif de reconstitution sur l'embout jusqu'au transpercement de ce dernier et son engagement complet dans la douille réceptrice pour que le dispositif de reconstitution soit opérationnel.When using the bag, simply remove the sterile packaging if there is one, insert the stopper of a vial into the socket of the device in order to pierce the stopper, then press the vial-reconstitution device assembly onto the tip until the latter is pierced and its complete engagement in the receiving socket so that the reconstitution device is operational.
La face fiole du dispositif peut être conventionnelle et comporter une douille classique pour la réception d'une fiole également classique.The vial face of the device can be conventional and include a conventional socket for the reception of an equally conventional vial.
Avantageusement, le dispositif de reconstitution est pourvu de moyens de positionnement et retenue, au moins dans la première des positions susdites, de la douille d'embout sur l'embout de la tubulure d'injection de la poche souple. L'invention a également pour objet l'ensemble constitué d'une poche souple munie d'au moins une tubulure d'injection à embout prépositionné dans ladite première position de retenue dans la douille concernée du dispositif de reconstitution.Advantageously, the reconstitution device is provided with means for positioning and retaining, at least in the first of the aforementioned positions, the tip socket on the tip of the injection pipe of the flexible bag. The invention also relates to the assembly consisting of a flexible bag provided with at least one injection tube with a prepositioned nozzle in said first retaining position in the socket concerned of the reconstitution device.
Le dispositif de l'invention présente donc des avantages substantiels notamment au niveau de la facilité de gestion et d'utilisation.The device of the invention therefore has substantial advantages, particularly in terms of ease of management and use.
D'autres caractéristiques et avantages ressortiront de la description qui va suivre d'un mode de réalisation du dispositif de l'invention, description donnée à titre d'exemple uniquement et en regard du dessin annexé sur lequel : - Figure 1 est une vue en coupe axiale d'un dispositif de reconstitution selon l'invention ;Other characteristics and advantages will emerge from the description which follows of an embodiment of the device of the invention, description given by way of example only and with reference to the appended drawing in which: - Figure 1 is a view in axial section of a reconstitution device according to the invention;
Figure 2 illustre le dispositif de la figure 1 en place en position d'attente sur l'extrémité d'une tubulure d'injection d'une poche souple et, - Figure 3 représente le dispositif de la figure 2 dans la seconde position, opérationnelle. Le dispositif de reconstitution représenté en 1 sur la figure 1 comprend une aiguille creuse 2 traversant un support circulaire 3 prolongé vers chaque extrémité pointue de l'aiguille, d'une douille cylindrique.Figure 2 illustrates the device of Figure 1 in place in the standby position on the end of an injection tubing of a flexible bag and, - Figure 3 shows the device of Figure 2 in the second position, operational . The reconstitution device shown at 1 in FIG. 1 comprises a hollow needle 2 passing through a circular support 3 extended towards each pointed end of the needle, with a cylindrical sleeve.
L'une des douilles (4) est destinée à accueillir (figures 2 et 3) l'embout 5 d'une tubulure d'injection 6 d'une poche souple 7.One of the sockets (4) is intended to receive (FIGS. 2 and 3) the end piece 5 of an injection pipe 6 of a flexible bag 7.
L'autre douille 8, disposée tête-bêche par rapport à la douille 4, présente un diamètre plus large pour recevoir l'embouchure munie d'un bouchon 9 (figure 3) d'une fiole 10 de médicament par exemple. La douille 8 présente un diamètre interne adapté à la fiole 10 et est obturée en période de non utilisation par un bouchon B à des fins de sécurité. La longueur de la douille 8 est légèrement supérieure à celle de la partie saillante de l'aiguille 2.The other socket 8, disposed head to tail with respect to the socket 4, has a larger diameter for receiving the mouthpiece provided with a stopper 9 (FIG. 3) of a vial 10 of medication, for example. The socket 8 has an internal diameter adapted to the vial 10 and is closed during periods of non-use by a plug B for safety purposes. The length of the sleeve 8 is slightly greater than that of the protruding part of the needle 2.
La douille 4 est très sensiblement plus longue que la partie saillante de l'aiguille 2 afin de recevoir (figure 2) la totalité de l'embout 5 dans une zone à distance de l'extrémité pointue de ladite aiguille. Le diamètre interne de la douille 4 correspond au diamètre externe de l'embout 5 dont la paroi est en matériau élastique.The sleeve 4 is very substantially longer than the projecting part of the needle 2 in order to receive (FIG. 2) the whole of the end piece 5 in an area at a distance from the pointed end of said needle. The internal diameter of the sleeve 4 corresponds to the external diameter of the nozzle 5, the wall of which is made of elastic material.
L'embout 5 est de structure conventionnelle en un matériau tel que du latex permettant son transpercement par l'aiguille 2, le trou de passage se refermant de lui-même après retrait de l'aiguille, de même que le matériau du bouchon 9. A son orifice d'entrée, la douille 4 est munie intérieurement d'un léger bourrelet annulaire 11 , discontinu comme représenté ou non, cependant qu'à une distance de ce bourrelet 11 correspondant à la longueur de l'embout 5 sont ménagées une ou plusieurs petites saillies internes, par exemple deux saillies 12 diamétralement opposées, conformées à l'extrémité de deux languettes 13 découpées dans la paroi de la douille 4.The nozzle 5 is of conventional structure made of a material such as latex allowing it to be pierced by the needle 2, the passage hole closing by itself after withdrawal of the needle, as is the material of the plug 9. At its inlet, the sleeve 4 is internally provided with a slight annular bead 11, discontinuous as shown or not, however at a distance from this bead 11 corresponding to the length of the nozzle 5 are formed one or several small internal protrusions, for example two diametrically opposite protrusions 12, shaped at the end of two tongues 13 cut in the wall of the socket 4.
Le dispositif 1 est monobloc et réalisé par exemple par moulage d'une matière plastique appropriée.The device 1 is in one piece and produced for example by molding an appropriate plastic material.
La figure 2 représente le dispositif 1 pré-positionné sur la tubulure d'injection 6, en position d'attente. Le dispositif 1 se trouve dans sa première position stable, l'embout 5 ayant été engagé dans la douille 4 à force pour vaincre, grâce à l'élasticité de l'embout, le bourrelet d'entrée 11 , l'embout 5 étant introduit complètement et étant arrêté dans cette première position par les deux saillies butées 12. Dans cette position stable d'attente, la pointe de l'aiguille 2 est maintenue à distance de l'embout 5 et le dispositif 1 fait corps avec la poche souple 7. L'ensemble peut donc être manipulé, conditionné dans un emballage souple stérile, stocké et géré comme un objet unique. Lors de l'utilisation de la poche 7, c'est à dire lorsque l'on veut mélanger le contenu de la fiole 10, avec un liquide de dilution par exemple contenu dans la poche. Le dispositif 1 est d'abord placé sur la tubulure 6 dans la position de la figure 2 (position d'attente). Puis, la fiole 10 est introduite par son bouchon 9 dans la douille 8 en sorte de transpercer le bouchon. Enfin, l'ensemble dispositif 1 -fiole 10 est pressé en direction de la poche 7 afin de faire transpercer l'embout 5 par l'aiguille.FIG. 2 shows the device 1 pre-positioned on the injection pipe 6, in the standby position. The device 1 is in its first stable position, the end piece 5 having been engaged in the socket 4 by force to overcome, thanks to the elasticity of the end piece, the inlet bead 11, the end piece 5 being introduced completely and being stopped in this first position by the two stop projections 12. In this stable waiting position, the tip of the needle 2 is kept at a distance from the nozzle 5 and the device 1 is integral with the flexible bag 7. The assembly can therefore be handled, packaged in a sterile flexible packaging. , stored and managed as a single object. When using the bag 7, that is to say when one wants to mix the contents of the vial 10, with a dilution liquid for example contained in the bag. The device 1 is first placed on the tubing 6 in the position of Figure 2 (standby position). Then, the vial 10 is introduced through its stopper 9 into the socket 8 so as to pierce the stopper. Finally, the device assembly 1-flask 10 is pressed in the direction of the pocket 7 in order to pierce the tip 5 by the needle.
Au début de ce mouvement, il faut vaincre la légère résistance élastique des saillies 12 qui s'escamotent pour laisser passer l'embout, puis la totalité de l'embout 5 est transpercée par l'aiguille 2 et enfin, l'embout vient en butée dans la seconde position stable du dispositif 1 contre un cône 14 ménagé dans le fond de la douille 4.At the start of this movement, it is necessary to overcome the slight elastic resistance of the projections 12 which retract to allow the end piece to pass, then the entire end piece 5 is pierced by the needle 2 and finally, the end piece comes in stop in the second stable position of the device 1 against a cone 14 formed in the bottom of the socket 4.
Les deux récipients 7 et 10 sont alors en communication via l'aiguille 2 et la tubulure 6.The two containers 7 and 10 are then in communication via the needle 2 and the tube 6.
Il est possible bien entendu de réaliser cette communication en engageant d'abord le bouchon 9 de la fiole 10 dans la douille 8 pour transpercer le bouchon, puis en engageant l'ensemble dispositif 1 -fiole 10 sur l'embout 5 pour, enfin, transpercer l'embout 5 et amener l'ensemble dans la position de la figure 3.It is of course possible to carry out this communication by first engaging the stopper 9 of the vial 10 in the socket 8 to pierce the stopper, then by engaging the device 1-flask 10 assembly on the nozzle 5 for, finally, pierce the nozzle 5 and bring the assembly into the position of figure 3.
Le dispositif de l'invention présente l'avantage de permettre le retrait de l'ensemble dispositif 1 -fiole 10 de l'embout 5 après l'opération de reconstitution. Ainsi, l'opérateur se retrouve face à une poche 7 dans laquelle il pourra, via la tubulure 6, faire une injection additionnelle si nécessaire. Suivant un autre avantage, la séparation entre la poche 7 et l'ensemble 1-10 est souhaitable pour un traitement optimisé des déchets hospitaliers.The device of the invention has the advantage of allowing the removal of the device 1-flask 10 assembly from the end piece 5 after the reconstitution operation. Thus, the operator finds himself facing a pocket 7 in which he can, via the tubing 6, make an additional injection if necessary. According to another advantage, the separation between the bag 7 and the assembly 1-10 is desirable for an optimized treatment of hospital waste.
Enfin, l'invention n'est évidemment pas limitée au mode de réalisation représenté et décrit ci-dessus mais en couvre au contraire toutes les variantes, notamment en ce qui concerne les moyens 11 , 12 de positionnement-blocage de l'embout 5 dans sa première position. Il est à noter que la douille 8 peut éventuellement être munie intérieurement à la manière connue d'une ou plusieurs saillies, trois par exemple, telles que représentées en 15 sur les figures, pour retenir élastiquement en position d'enfoncement correct le bouchon 9 de la fiole, et extérieurement également à la manière connue, d'une ou plusieurs saillies, trois par exemple, telles que représentées en 16 pour retenir le bouchon B. Finally, the invention is obviously not limited to the embodiment shown and described above, but on the contrary covers all variants thereof, in particular as regards the means 11, 12 for positioning-blocking the end piece 5 in his first position. It should be noted that the socket 8 can optionally be provided internally in the known manner with one or more projections, three for example, as shown at 15 in the figures, for retain elastically in the correct insertion position the stopper 9 of the vial, and externally also in the known manner, of one or more protrusions, three for example, as shown in 16 for retaining the stopper B.
