A flexible bladder ( 31 ) or a squeeze bulb ( 33 ) is connected with an air inlet ( 116 ) of the filling infuser to inject pressurized air into the supply container and accelerate the transfer of medicinal liquids from the supply container to the flexible pouch.

Description

La présente invention concerne un dispositif de remplissage d'une poche souple.The present invention relates to a device for filling a flexible bag.

L'invention trouve une application particulièrement avantageuse, mais non exclusive, dans le domaine de l'injection de liquide à usage médical.The invention finds a particularly advantageous, but not exclusive, application in the field of liquid injection for medical use.

En médecine, l'injection de liquide est couramment utilisée notamment lors d'opérations de transfusion, de perfusion, de nutrition artificielle par voie veineuse ou digestive, d'injection de liquide de contraste, etc. Parmi toutes les techniques connues, l'injection haute pression de liquide conditionné en poche souple constitue l'une des plus adaptée au milieu médical en raison de l'hygiène satisfaisante qu'elle procure.In medicine, the injection of liquid is commonly used especially during transfusion operations, perfusion, artificial nutrition by the venous or digestive system, injection of contrast liquid, etc. Among all the known techniques, the high pressure injection of liquid packaged in flexible pouch is one of the most adapted to the medical environment because of the satisfactory hygiene it provides.

Le principe consiste à utiliser une poche souple qui, comme son nom l'indique, est classiquement constituée d'une poche en matériau souple contenant d'une part un liquide médical à injecter et dotée d'autre part d'un raccord de liaison réversible. Ce raccord est quant à lui connecté, éventuellement via une canalisation intermédiaire de longueur adéquate, à un conduit d'injection amovible tel qu'un cathéter ou une aiguille hypodermique. La poche souple est alors placée dans une enceinte contenant un liquide inerte susceptible d'être mis en pression afin de déformer la poche, forçant ainsi le liquide à s'écouler par le conduit d'injection, le cas échéant via la canalisation intermédiaire.The principle consists in using a flexible pouch which, as its name suggests, is conventionally constituted of a pouch of flexible material containing on the one hand a medical liquid to be injected and on the other hand a reversible connection fitting . This connection is connected, possibly via an intermediate pipe of adequate length, to a removable injection conduit such as a catheter or a hypodermic needle. The flexible bag is then placed in an enclosure containing an inert liquid that can be pressurized in order to deform the bag, thereby forcing the liquid to flow through the injection conduit, where appropriate via the intermediate pipe.

Si l'injection de liquide conditionné en poche souple constitue une opération techniquement satisfaisante, le remplissage de la poche proprement dite demeure une opération empirique puisqu'elle s'effectue simplement par gravité. On utilise généralement un dispositif de remplissage constitué par un simple perfuseur de remplissage que l'on vient mettre en place de manière amovible à l'extrémité du raccord de liaison réversible de la poche souple. Le document US 3 807 467 divulgue un dispositif similaire à celui de la demande avec la différence que les conteneurs sont remplis à l'envers. Les conteneurs ont donc une position qui ne permet pas leurs remplissage par gravité.If the injection of liquid packaged in a flexible bag is a technically satisfactory operation, the filling of the bag itself remains an empirical operation since it is carried out simply by gravity. In general, a filling device consisting of a simple infusor filling that is just put in place removably at the end of the reversible connection connection of the flexible bag. The document US 3,807,467 discloses a device similar to that of the application with the difference that the containers are filled upside down. The containers therefore have a position that does not allow their filling by gravity.

Le perfuseur de remplissage comporte classiquement deux conduits. Le premier conduit relie son extrémité distale qui est destinée à être connectée à tout dispositif extérieur, à son extrémité proximale qui est destinée à être connectée au volume interne de la poche souple. Le second conduit relie quant à lui ladite extrémité distale à une prise d'air donnant sur l'extérieur et généralement couplée à un filtre imperméable au liquide.The filling infuser conventionally comprises two ducts. The first conduit connects its distal end which is intended to be connected to any external device at its proximal end which is intended to be connected to the internal volume of the flexible bag. The second conduit connects said distal end to an air intake to the outside and generally coupled to a filter impermeable to the liquid.

Lors du remplissage de la poche souple, le perfuseur est simplement maintenu vertical, de telle sorte que son extrémité distale soit orientée vers le haut afin que cette dernière puisse être enfoncée dans le bouchon du récipient d'alimentation orienté quant à lui vers le bas. La prise d'air peut alors jouer pleinement son rôle en permettant une entrée d'air à l'intérieur du récipient d'alimentation, via le second conduit, et conséquemment l'écoulement du liquide hors dudit récipient d'alimentation, par le premier conduit. Le liquide va alors pouvoir s'écouler dans le raccord puis remplir la poche souple.When filling the flexible bag, the infuser is simply held vertical, so that its distal end is oriented upwards so that the latter can be pressed into the cap of the supply container oriented downwards. The air intake can then play its full role by allowing an air inlet inside the supply container, via the second conduit, and consequently the flow of liquid out of said supply container, by the first leads. The liquid will then flow into the fitting and fill the flexible bag.

Ce type de dispositif de remplissage fonctionnant par simple gravité présente toutefois l'inconvénient de rendre l'opération de remplissage particulièrement longue.This type of filling device operating by simple gravity, however, has the disadvantage of making the filling operation particularly long.

Aussi le problème technique à résoudre, par l'objet de la présente invention, est de proposer un dispositif de remplissage d'une poche souple, destiné à introduire un liquide dans une poche souple reliée à un perfuseur de remplissage pourvu d'une prise d'air, dispositif de remplissage qui permettrait d'éviter les problèmes de l'état de la technique en permettant une accélération sensible de l'écoulement du liquide dans la poche souple et donc un remplissage rapide.Also the technical problem to be solved by the object of the present invention is to provide a device for filling a flexible bag, intended to introduce a liquid into a flexible bag connected to a filling infuser provided with a plug. air, filling device that would avoid the problems of the state of the art by allowing a significant acceleration of the flow of liquid in the flexible bag and thus a fast filling.

La solution au problème technique posé consiste, selon la présente invention, en ce que le dispositif de remplissage comporte:

  • des moyens de fixation de la poche souple aptes à positionner vers le haut l'extrémité distale du perfuseur de remplissage,
  • des moyens de maintien d'un récipient d'alimentation contenant le liquide à introduire, lesdits moyens de maintien étant aptes à positionner ledit récipient d'alimentation dans une position telle que le liquide s'écoule par gravité lorsque ledit récipient est connecté au perfuseur de remplissage,
  • des moyens de compression de l'air,
  • des moyens de liaison reliant les moyens de compression et la prise d'air du perfuseur de remplissage.
The solution to the technical problem posed consists, according to the present invention, in that the filling device comprises:
  • means for fixing the flexible pouch able to position the distal end of the filling infuser upwards,
  • means for holding a supply container containing the liquid to be introduced, said holding means being able to position said supply container in a position such that the liquid flows by gravity when said container is connected to the infusor of filling,
  • means for compressing the air,
  • connecting means connecting the compression means and the air intake of the filling infuser.

Ainsi positionné, le récipient d'alimentation est classiquement raccordé à la poche souple par le perfuseur de remplissage, de sorte que le liquide peut s'écouler par gravité. Mais en plus, la prise d'air qui est également connectée au récipient d'alimentation communique avec des moyens de compression susceptibles d'amener de l'air sous pression à l'intérieur dudit récipient. La mise en oeuvre de ces moyens de compression va par conséquent accroître la pression de l'air dans le récipient d'alimentation. Cette surpression va alors pousser le liquide par le seul orifice d'écoulement accessible, c'est-à-dire celui ménagé dans le perfuseur et conduisant à la poche souple. Le remplissage s'en trouve alors avantageusement accéléré.Thus positioned, the supply container is conventionally connected to the flexible bag by the filling infuser, so that the liquid can flow by gravity. But in addition, the air intake which is also connected to the supply container communicates with compression means capable of supplying pressurized air inside said container. The implementation of these compression means will therefore increase the pressure of the air in the supply container. This pressure will then push the liquid through the only accessible flow orifice, that is to say that formed in the infusor and leading to the flexible bag. The filling is then advantageously accelerated.

La présente invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to the features which will emerge during the following description, which should be considered in isolation or in all their possible technical combinations.

La figure 1 illustre une poche souple (100) prête à être utilisée avec un dispositif de remplissage (1) objet de la présente invention, c'est à dire que la poche souple (100) est couplée à un perfuseur de remplissage (110). La poche souple (100) est classiquement constituée d'une poche (101) réalisée en matériau souple et destinée à contenir un liquide médical à injecter. La poche (101) est dotée d'un raccord de liaison réversible (102) comportant ici une canalisation (103) à l'extrémité de laquelle est monté libre en rotation un écrou (104). Dans cet exemple de réalisation, le raccord de liaison réversible (102) peut donc coopérer par vissage avec un filetage (111) ménagée à l'extrémité proximale (112) du perfuseur de remplissage (110) amovible.The figure 1 illustrates a flexible bag (100) ready to be used with a filling device (1) object of the present invention, that is to say that the flexible bag (100) is coupled to a filling infuser (110). The flexible pouch (100) is conventionally made of a pouch (101) made of flexible material and intended to contain a medical liquid to be injected. The bag (101) is provided with a reversible connection fitting (102), here comprising a pipe (103) at the end of which a nut (104) is rotatably mounted. In this exemplary embodiment, the reversible connection fitting (102) can thus cooperate by screwing with a thread (111) formed at the proximal end (112) of the removable filling perfume (110).

Conformément à la figure 2, le perfuseur de remplissage (110) comporte de manière tout aussi classique deux conduits (114, 115). Le premier conduit (114) relie son extrémité distale (113) qui est destinée à être connectée à tout dispositif extérieur, à son extrémité proximale (112) qui est destinée à être connectée au volume interne de la poche souple (100), via le raccord de liaison réversible (102). Le second conduit (115) relie quant à lui l'extrémité distale (113) à une prise d'air (116) latérale donnant sur l'extérieur et dotée d'un filtre (117) imperméable au liquide mais bien entendu perméable à l'air. Le perfuseur de remplissage (110) comporte en outre une paire de pattes supports (118) disposées latéralement en opposition l'une de l'autre et perpendiculairement à l'axe longitudinal dudit perfuseur de remplissage (110).In accordance with the figure 2 the filling infuser (110) is equally conventional with two ducts (114, 115). The first conduit (114) connects its distal end (113) which is intended to be connected to any external device, at its proximal end (112) which is intended to be connected to the internal volume of the flexible pouch (100), via the reversible link connection (102). The second duct (115) connects the distal end (113) to an external air intake (116) on the outside and provided with a filter (117) impermeable to the liquid but of course permeable to the liquid. 'air. The filling infuser (110) further includes a pair of support tabs (118) laterally disposed in opposition to each other and perpendicular to the longitudinal axis of said fill infuser (110).

La figure 2 illustre en outre le rôle du perfuseur (110) lors d'une classique opération de remplissage. Ainsi qu'on peut le voir, le perfuseur de remplissage (110) est maintenu verticalement de manière à ce que son extrémité distale (113) soit orientée vers le haut ; la poche (101) non représentée ici pendant simplement en dessous. Un récipient d'alimentation (200) contenant un liquide (201) est quant à lui orienté vers le bas, de manière à pouvoir être couplé au perfuseur de remplissage (110) par l'intermédiaire de son bouchon (202) à travers lequel est enfoncée l'extrémité distale (113) dudit perfuseur de remplissage (110). Afin de faciliter ce couplage et d'assurer ensuite une bonne étanchéité, le bouchon (202) est constitué d'un matériau suffisamment tendre pour permettre l'introduction de la partie distale (113), avantageusement ménagée en forme de pointe.The figure 2 illustrates further the role of the infusor (110) in a conventional filling operation. As can be seen, the filling infuser (110) is held vertically so that its distal end (113) facing upwards; the pocket (101) not shown here for just below. A supply container (200) containing a liquid (201) is directed downwards, so that it can be coupled to the filling infuser (110) via its plug (202) through which is depressed the distal end (113) of said fill infuser (110). To facilitate this coupling and then ensure a good seal, the plug (202) is made of a sufficiently soft material to allow the introduction of the distal portion (113), advantageously formed in the form of a tip.

La prise d'air (116) peut alors jouer pleinement son rôle et permettre une entrée d'air à l'intérieur du récipient d'alimentation (200), via le second conduit (115) ; le filtre (117) interdisant l'écoulement du liquide (201) vers l'extérieur. L'écoulement du liquide (201) hors dudit récipient d'alimentation (200), par le premier conduit (114), peut ainsi se réaliser, autorisant par la même le remplissage de la poche souple (100).The air intake (116) can then play its full role and allow an air inlet inside the supply container (200) via the second conduit (115); the filter (117) preventing the flow of the liquid (201) outwards. The flow of liquid (201) out of said supply container (200), through the first conduit (114), can be achieved, thereby allowing the filling of the flexible bag (100).

Il est à noter que l'ensemble des figures 3 à 9 représente, à titre d'exemple, des systèmes de remplissage comportant à chaque fois deux dispositifs de remplissage conforme à l'objet de la présente invention. La combinaison de plusieurs dispositifs de remplissage ne changeant rien à la structure ni au principe de fonctionnement de chacun d'entre eux considéré isolément, la description de ces figures ne concernera à chaque fois, et pour des raisons évidentes de simplicité, qu'un seul desdits dispositifs de remplissage.It should be noted that all Figures 3 to 9 represents, by way of example, filling systems comprising in each case two filling devices according to the subject of the present invention. The combination of several filling devices does not change the structure or the operating principle of each of them considered in isolation, the description of these figures will concern each time, and for obvious reasons of simplicity, only one said filling devices.

Ainsi donc, la figure 3 illustre un dispositif de remplissage (1) conforme à l'invention, c'est-à-dire destiné à introduire un liquide (201), contenu dans un récipient d'alimentation (200), dans une poche souple (100) pourvu d'un perfuseur de remplissage (110) lui-même doté d'une prise d'air (116).So, the figure 3 illustrates a filling device (1) according to the invention, that is to say intended to introduce a liquid (201) contained in a supply container (200) into a flexible bag (100) provided with a filling infuser (110) itself having an air intake (116).

Dans ce premier mode de réalisation, le dispositif de remplissage (1) est pourvu de moyens de fixation (10) permettant de positionner la poche souple (100) de telle manière que l'extrémité distale (113) du perfuseur de remplissage (110) soit orientée vers le haut.In this first embodiment, the filling device (1) is provided with fixing means (10) for positioning the flexible bag (100) in such a way that the distal end (113) of the filling infuser (110) is facing up.

Le dispositif de remplissage (1) comporte également des moyens de maintien (20) permettant de positionner un récipient d'alimentation (200) à la verticale de la poche souple (100), dans une position telle que le liquide (201) peut s'écouler par gravité lorsque ledit récipient d'alimentation (200) est classiquement connecté au perfuseur de remplissage (110).The filling device (1) also comprises holding means (20) for positioning a supply container (200) in the vertical position of the flexible bag (100) in a position such that the liquid (201) can be gravity flow when said feed container (200) is conventionally connected to the fill infuser (110).

Le dispositif de remplissage (1) est en outre doté de moyens de compression (30) de l'air, constitué ici par un ballon souple (31) compressible par l'intermédiaire d'une pédale pivotante (32).The filling device (1) is furthermore provided with compression means (30) for the air, constituted here by a flexible balloon (31) compressible via a pivoting pedal (32).

Enfin le dispositif de remplissage (1) comporte des moyens de liaison (40) reliant les moyens de compression (30) et la prise d'air (116) du perfuseur de remplissage (110).Finally, the filling device (1) comprises connecting means (40) connecting the compression means (30) and the air intake (116) of the filling infusor (110).

Ainsi qu'on peut le voir notamment sur la figure 4, les moyens de fixation (10) sont aptes à coopérer par emboîtement avec au moins une portion du perfuser de remplissage (110). Le maintien est ainsi réalisé avantageusement sur une partie véritablement rigide de la poche souple (100).As can be seen in particular on the figure 4 , the fastening means (10) are able to cooperate by interlocking with at least a portion of the filling perfuser (110). The maintenance is thus advantageously performed on a truly rigid portion of the flexible bag (100).

Dans l'exemple de réalisation illustré aux figures 3 à 8, les moyens de fixation (10) comportent un évidement de fixation (11) de forme sensiblement complémentaire à la partie proximale (112) du perfuseur de remplissage (110).In the exemplary embodiment illustrated in Figures 3 to 8 , the fastening means (10) comprise a fixing recess (11) of substantially complementary to the proximal portion (112) of the filling infusor (110).

Les moyens de fixation (10) comportent en outre une ouverture traversante verticale (12) s'étendant entre l'évidement de fixation (11) et l'extérieur. Cette ouverture traversante verticale (12) est apte à permettre le passage du perfuseur de remplissage (110) orienté verticalement, et notamment sa partie proximale (112), lors de sa mise en place dans l'évidement de fixation (11), par insertion suivant une direction sensiblement horizontale.The fastening means (10) further comprise a vertical through opening (12) extending between the fixing recess (11) and the outside. This vertical through opening (12) is adapted to allow the passage of the vertically oriented filling infuser (110), and in particular its proximal portion (112), when it is placed in the insertion recess (11), by insertion following a substantially horizontal direction.

Les moyens de fixation (10) comportent enfin une fente traversante horizontale (13) s'étendant entre l'évidement de fixation (11) et l'extérieur, la fente traversante horizontale (13) étant apte à permettre le passage des pattes supports latérales (118) lors de la mise en place du perfuseur de remplissage (110) dans l'évidement de fixation (11), par insertion suivant une direction sensiblement horizontale.The fastening means (10) finally comprise a horizontal through slot (13) extending between the fixing recess (11) and the outside, the horizontal through slot (13) being able to allow the lateral support tabs to pass therethrough (118) when placing the filling infuser (110) in the fixing recess (11) by insertion in a substantially horizontal direction.

Les moyens de maintien (20) comportent quant à eux un évidement de maintien (21) de forme sensiblement complémentaire à l'extrémité du récipient d'alimentation (200), portant le bouchon (202).The holding means (20) comprise in turn a holding recess (21) of substantially complementary shape to the end of the supply container (200) carrying the plug (202).

Dans le cas présent, l'évidement de maintien (21) présente une forme cylindrique dont le diamètre est sensiblement complémentaire aux cols des flacons d'alimentation les plus couramment utilisés.In this case, the holding recess (21) has a cylindrical shape whose diameter is substantially complementary to the necks of the most commonly used feed bottles.

Les moyens de maintien (20) sont positionnés à proximité directe des moyens de fixation (10) puisqu'ils sont respectivement destinés à coopérer avec le récipient d'alimentation (200) et avec le perfuseur de remplissage (110) lorsque ces derniers sont connectés entre eux. Aussi, les moyens de maintien (20) comporte une fente traversante verticale (22) s'étendant entre l'évidement de maintien (21) et l'extérieur. Cette fente traversante verticale (22) est apte à permettre le passage de la partie distale (113), orientée verticalement, lors de la mise en place du perfuseur de remplissage (110) dans l'évidement de fixation (11), par insertion suivant une direction sensiblement horizontale.The holding means (20) are positioned in the direct vicinity of the fastening means (10) since they are respectively intended to cooperate with the supply container (200) and the filling infusor (110) when they are connected between them. Also, the means of maintenance (20) has a vertical through slot (22) extending between the holding recess (21) and the outside. This vertical through slot (22) is adapted to allow the passage of the distal portion (113), oriented vertically, during the introduction of the filling infusor (110) into the fixing recess (11), by inserting next a substantially horizontal direction.

De manière particulièrement avantageuse, la fente traversante verticale (22) et l'ouverture traversante verticale (12) sont directement communicantes entre elles.Particularly advantageously, the vertical through slot (22) and the vertical through opening (12) are directly communicating with each other.

Ainsi qu'on peut le voir dans l'exemple de la figure 4, les moyens de compression (30) comportent un ballon souple (31) compressible par l'intermédiaire d'une pédale pivotante (32).As can be seen in the example of figure 4 , the compression means (30) comprise a flexible balloon (31) compressible via a pivoting pedal (32).

On observe également que les moyens de liaisons (40) comportent une canalisation (41) reliant le ballon souple (31) à un évent (42) apte à coopérer par emboîtement avec la prise d'air (116) du perfuseur de remplissage (110). Les figures 5 à 8 le fonctionnement du dispositif de remplissage (1) selon l'invention.It is also observed that the connecting means (40) comprise a pipe (41) connecting the flexible balloon (31) to a vent (42) able to cooperate by interlocking with the air intake (116) of the filling infuser (110). ). The Figures 5 to 8 the operation of the filling device (1) according to the invention.

Conformément à la figure 5, toute opération de remplissage débute par la mise en place de la poche souple (100) couplée à son perfuseur de remplissage (110). Ce dernier, orienté verticalement, partie proximale (113) vers le haut et prise d'air (116) en avant, est introduit horizontalement à travers simultanément l'ouverture traversante verticale (12), la fente traversante horizontale (13) et la fente traversante verticale (22).In accordance with the figure 5 , all filling operation begins with the introduction of the flexible bag (100) coupled to its filling infusor (110). The latter, vertically oriented, proximal portion (113) upwards and air intake (116) forward, is introduced horizontally through simultaneously the vertical through opening (12), the horizontal through slot (13) and the slot vertical crossing (22).

L'insertion se termine conformément à la figure 6 lorsque, après une ferme pression, la partie proximale (112) se trouve emboîtée dans l'évidement de fixation (11) formant les moyens de fixation (10). L'extrémité de la prise d'air (116) est alors emboîtée dans l'évent (42) de forme complémentaire et la partie distale (113) du perfuseur de remplissage (110) s'étend axialement dans l'évidement de maintien (21) cylindrique, formant les moyens de maintien (20).The insertion ends according to the figure 6 when, after a firm pressure, the proximal portion (112) is nested in the recess fastening means (11) forming the fastening means (10). The end of the air intake (116) is then nested in the complementary shaped vent (42) and the distal portion (113) of the filling infuser (110) extends axially into the holding recess ( 21), forming the holding means (20).

Ainsi qu'on peut le voir sur la figure 7, le récipient d'alimentation (200) est ensuite présenté verticalement, et bouchon (202) vers le bas, en direction des moyens de maintien (20). Le bouchon (202) est alors enfoncé fermement sur la partie distale (113) du perfuseur de remplissage (110) jusqu'au positionnement complet du col du récipient d'alimentation (200) dans l'évidement de maintien (21).As can be seen on the figure 7 , the supply container (200) is then presented vertically, and plug (202) downward, towards the holding means (20). The stopper (202) is then pressed firmly onto the distal portion (113) of the infusion infuser (110) until the full position of the neck of the supply container (200) is in the holding recess (21).

Conformément à la figure 8, il ne reste plus alors qu'à mettre en oeuvre les moyens de compression (30), en actionnant ici manuellement une pédale pivotante (32). L'écrasement partiel du ballon compressible (31) va ainsi générer une surpression qui va se propager jusqu'à l'évent (42), par l'intermédiaire des moyens de liaison (40), puis jusqu'à l'intérieur du récipient d'alimentation (200) par l'intermédiaire successivement de la prise d'air (116) et du conduit (115). L'augmentation de pression va alors forcer le liquide (201) à s'écouler par le conduit (114), et conséquemment va accélérer sensiblement le remplissage de la poche souple (100).In accordance with the figure 8 , it remains then only to implement the compression means (30), manually operating here a pivoting pedal (32). The partial crushing of the compressible flask (31) will thus generate an overpressure that will propagate to the vent (42), via the connecting means (40), and then to the inside of the container supply (200) via successively the air intake (116) and the conduit (115). The increase in pressure will then force the liquid (201) to flow through the conduit (114), and consequently substantially accelerate the filling of the flexible bag (100).

Dans le second mode de réalisation illustré à la figure 9, les moyens de compression (30) se présentent simplement sous la forme d'un ballon souple (33) manuellement compressible.In the second embodiment illustrated in figure 9 , the compression means (30) are simply in the form of a flexible balloon (33) manually compressible.

Naturellement, l'invention concerne également tout système de remplissage comportant au moins deux dispositifs de remplissage (1) tels que précédemment décrits. La configuration avec deux dispositifs de remplissage (1) combinés, tel que les systèmes représentés aux figures 3 à 9, est particulièrement avantageuse lorsqu'il est nécessaire de remplir simultanément deux poches simples ou une poche double avec deux liquides. C'est par exemple le cas avec les doubles poches gadolinium et sérum physiologique.Naturally, the invention also relates to any filling system comprising at least two filling devices (1) as previously described. Configuration with two filling devices (1) combined, such as the systems shown in Figures 3 to 9 is particularly advantageous when it is necessary to simultaneously fill two single bags or a double bag with two liquids. This is the case, for example, with gadolinium and physiological saline bags.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons comme définis par les revendications.Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations as defined by the claims.
