On connaît déjà des appareils du type précité pour l'introduction d'une substance médicamenteuse ou de sang dans un organisme dans lesquels les éléments constitutifs sont fabriqués et vendus séparément, et doivent donc être reliés les uns aux autres au moment de leur utilisation. Cette conception présente les inconvénients d'une parte que la stérilisation des éléments constitutifs de l'appareil doit être faite séparément et d'autre part que les manipulations destinées à relier les éléments les uns aux autres risquent d'entraîner la contamination de l'ensemble de l'appareil. Apparatuses of the aforementioned type are already known for the introduction of a medicinal substance or of blood into an organism in which the constituent elements are produced and sold separately, and must therefore be connected to one another at the time of their use. This design has the disadvantages of one part that the sterilization of the components of the device must be done separately and on the other hand that the manipulations intended to connect the elements to each other may cause contamination of the whole of the device.

Le but de cette invention consiste donc à fournir un appareil de perfusion du type précité qui obvie aux inconvénients précités, c'est-à-dire qui se présente comme un tout stérilisable en une seule opération et sans autre prêt à l'usage. Ce but est atteint par l'appareil de perfusion selon l'invention qui présente les caractéristiques énoncées dans la revendication 1. The object of this invention therefore consists in providing an infusion device of the aforementioned type which obviates the aforementioned drawbacks, that is to say which presents itself as a whole which can be sterilized in a single operation and without any other ready for use. This object is achieved by the perfusion apparatus according to the invention which has the characteristics set out in claim 1.

Le dessin annexé illustre schématiquement et à titre d'exemple une forme d'exécution de l'appareil de perfusion selon l'invention. The accompanying drawing illustrates schematically and by way of example an embodiment of the perfusion apparatus according to the invention.

La fig. 1 est une vue générale partiellement en coupe de l'appareil. Fig. 1 is a general view partially in section of the device.

La fig. 2 est une vue en coupe de la chambre et du dispositif compte-gouttes. Fig. 2 is a sectional view of the chamber and of the dropper device.

La fig. 3 est une vue en coupe d'une variante de la partie supérieure de l'appareil. Fig. 3 is a sectional view of a variant of the upper part of the device.

Comme illustré sur la fig. 1, I'appareil de perfusion comporte un récipient 1 en matière plastique souple présentant une chambre principale 2 servant de réservoir pour le liquide à infuser et une chambre annexe 3 servant de chambre compte-gouttes. As illustrated in fig. 1, the perfusion apparatus comprises a container 1 of flexible plastic material having a main chamber 2 serving as a reservoir for the liquid to be infused and an annex chamber 3 serving as a dropper chamber.

Dans la chambre compte-gouttes 3 est monté un dispositif compte-gouttes 4 se présentant sous la forme d'une cloche 5 dont le fond est percé d'un orifice calibré 6, cet orifice communiquant avec un tube d'entrée 7 traversant la paroi de séparation 8 entre le réservoir 2 et la chambre compte-gouttes 3 les mettant ainsi en communication. De plus, un tube de sortie 9 est prévu dans la paroi 8' formant l'extrémité inférieure de la chambre compte-gouttes 3 (voir également fig. 2). In the dropper chamber 3 is mounted a dropper device 4 in the form of a bell 5 whose bottom is pierced with a calibrated orifice 6, this orifice communicating with an inlet tube 7 passing through the wall separation 8 between the reservoir 2 and the dropper chamber 3 thus putting them in communication. In addition, an outlet tube 9 is provided in the wall 8 'forming the lower end of the dropper chamber 3 (see also fig. 2).

La partie supérieure du récipient - est munie d'un tube d'entrée 10 destiné à l'introduction du liquide dans le réservoir 2, et dont l'extrémité supérieure est fermée après remplissage de ce dernier. De plus, un tube additionnel 11 pour ajouter par exemple un additif soit juste avant le début de l'utilisation de l'appareil, soit au cours de la perfusion elle-même; I'extrémité supérieure de ce tube additionnel 11 est pourvu d'un disque 12, par exemple en cautchouc ou en matière plastique, destiné à être percé par exmeple au moyen d'une aiguille de seringue pour ajouter l'additif souhaité au liquide déjà contenu dans le réservoir 2. The upper part of the container - is provided with an inlet tube 10 intended for the introduction of the liquid into the reservoir 2, and the upper end of which is closed after filling of the latter. In addition, an additional tube 11 for adding, for example, an additive either just before the start of use of the device, or during the infusion itself; The upper end of this additional tube 11 is provided with a disc 12, for example in rubber or plastic, intended to be pierced for example by means of a syringe needle to add the desired additive to the liquid already contained in tank 2.

Selon une variante illustrée à la figure 3, le tube additionnel 11' muni de son disque obturateur 12' est disposé à l'intérieur d'une chambre supérieure 13 protégeant ainsi de toute contamination le disque obturateur à percer. According to a variant illustrated in FIG. 3, the additional tube 11 ′ provided with its shutter disc 12 ′ is disposed inside an upper chamber 13 thus protecting the shutter disc to be drilled from any contamination.

Le récipient 1 présente encore des pattes 14, 15 percées chacune d'une orifice 16, 17 et servant à la manipulation du récipient et à sa fixation à un support ou à un dispositif de suspension. The container 1 also has tabs 14, 15 each pierced with an orifice 16, 17 and used for handling the container and for fixing it to a support or to a suspension device.

La partie supérieure du récipient 1 est munie d'un tube 18 et un dispositif d'injection 19 comprenant une aiguille protégée avant usage par un capuchon. Le tuyau souple 18 est relié au tube de sortie 9 soit directement soit par l'entremise d'un raccord 20; de même le tuyau souple 18 est relié au dispositif d'injection 19 soit directement soit par l'entremise d'un raccord 21. Le tuyau souple 18 est également muni d'un organe de réglage et d'arrêt du débit 22 agissant par pression au moyen d'une roulette sur le tuyau lui-même. The upper part of the container 1 is provided with a tube 18 and an injection device 19 comprising a needle protected before use by a cap. The flexible pipe 18 is connected to the outlet tube 9 either directly or through a connector 20; similarly the flexible pipe 18 is connected to the injection device 19 either directly or by means of a fitting 21. The flexible pipe 18 is also provided with a flow control and stop member 22 acting by pressure by means of a roller on the pipe itself.

Comme illustré sur la fig. 1, l'appareil de perfusion complet peut être stocké avec un minimum d'encombrement, le tuyau souple 18 étant enroulé et le dispositif d'injection 19 introduit dans une poche 23 du récipient 1, ce dispositif d'injection 19 comportant un embout porte-aiguille. As illustrated in fig. 1, the complete perfusion device can be stored with a minimum of space, the flexible tube 18 being wound up and the injection device 19 introduced into a pocket 23 of the container 1, this injection device 19 comprising a nozzle holder -needle.

De préférence, le récipient 1 est fabriqué par soudage à haute fréquence de deux feuilles en matière plastique, par exemple du chlorure de polyvinyle, et de manière à incorporer directement au moment du soudage les autres éléments constitutifs, à savoir le dispositif compte-gouttes 4, le tube de sortie 9, le tube d'entrée 10 et le tube additionnel 11. Preferably, the container 1 is manufactured by high-frequency welding of two plastic sheets, for example polyvinyl chloride, and so as to incorporate directly at the time of welding the other constituent elements, namely the dropper device 4 , the outlet tube 9, the inlet tube 10 and the additional tube 11.

Ainsi, I'appareil de perfusion selon l'invention se présente comme un tout susceptible d'être stérilisé en une seule opération et d'être commercialisé prêt à l'emploi. De plus, cette conception permet également d'éviter les risques de contaminations dûs aux manipulations de connections nécessaires avec les appareils connus comportant plusieurs éléments séparés. Thus, the perfusion apparatus according to the invention is presented as a whole capable of being sterilized in a single operation and of being marketed ready for use. In addition, this design also makes it possible to avoid the risks of contamination due to the handling of necessary connections with known devices comprising several separate elements.
