Description

L'invention concerne un raccord pour tubulure de nutrition entérale.The invention relates to a connector for enteral nutrition tubing.

Ainsi qu'on le sait la nutrition entérale d'un patient consiste à amener dans l'estomac ou l'intestin au moyen d'une sonde suivant l'oesophage, une composition nutritive conditionnée dans un récipient situé à distance et auquel la sonde est connectée au moyen d'une tubulure dite tubulure de nutrition entérale.As is known, the enteral nutrition of a patient consists in bringing into the stomach or the intestine by means of a probe following the esophagus, a nutritive composition conditioned in a container situated at a distance and to which the probe is connected by means of a tubing called enteral nutrition tubing.

Il existe à ce jour plusieurs types de récipients munis de goulots de formats prédéterminés différents, choisis par les préparateurs des compositions nutritives, et à chacun de ces goulots, donc à chacun de ces types de récipients, correspond actuellement une tubulure spécifique munie en une extrémité d'un raccord adapté à coopérer avec ledit goulot. En pratique une chambre de goutte à goutte est interposée entre ce raccord et la partie flexible de la tubulure.To date, there are several types of receptacles provided with necks of different predetermined formats, chosen by the preparers of the nutritive compositions, and each of these necks, therefore to each of these types of receptacles, currently corresponds a specific tubing provided at one end. a fitting adapted to cooperate with said neck. In practice, a drip chamber is interposed between this fitting and the flexible part of the tubing.

L'invention vise, à des fins de standardisation, un raccord du type précité qui soit adapté à coopérer avec plusieurs formats prédéterminés de goulot. Une telle standardisation a pour intérêt de réduire les coûts de fabrication, et de nécessiter un moindre nombre de tubulures à garder en stock auprès de chaque lieu d'utilisation ; il en résulte un moindre volume de stockage et un plus faible coût global de tubulures à garder en stock.The invention aims, for standardization purposes, a coupling of the aforementioned type which is adapted to cooperate with several predetermined formats of neck. The advantage of such standardization is to reduce manufacturing costs and to require fewer tubes to be kept in stock at each place of use; this results in less storage volume and lower overall cost of tubing to keep in stock.

On connaît déjà, grâce au document US-A-1.366.789, un dispositif de raccordement d'un tube flexible à plusieurs types de bouteilles ou bocaux ordinaires, qui consiste en une base et en une pluralité de projections s'étendant sensiblement sur une même distance de celle-ci, chaque projection étant adaptée à coopérer, intérieurement ou par affrontement de tranches, avec un type de goulot de taille donnée. Cette base comporte une saillie tubulaire destinée à la fixation du tube, et une entrée d'air séparée.Already known from document US-A-1,366,789, a device for connecting a flexible tube to several types of ordinary bottles or jars, which consists of a base and a plurality of projections extending substantially over a same distance from the latter, each projection being adapted to cooperate, internally or by confrontation of slices, with a type of neck of given size. This base includes a tubular projection for fixing the tube, and a separate air inlet.

Quant au document US-A-3.850.341, il décrit un obturateur adapté à coopérer avec différents types de goulots, sans que soit prévue aucune communication avec une tubulure de nutrition.As for document US-A-3,850,341, it describes a shutter adapted to cooperate with different types of necks, without any communication being provided with a feeding tube.

L'invention propose à cet effet un dispositif pour le raccordement d'une tubulure de nutrition entérale à un récipient contenant une composition nutritive et muni d'un goulot, du type comportant une paroi transversale d'obturation et un jeu d'au moins deux jupes cylindriques élastiques coaxiales solidaires de la paroi transversale d'obturation avec laquelle elles forment un bouchon, et pouvant s'engager chacune intérieurement dans des goulots de récipients ayant des formats prédéterminés différents, caractérisé en ce qu'il est formé d'un raccord comportant cette paroi transversale d'obturation et cette jupe, et d'un embout perforateur indépendant, connu en soi, monté à une extrémité de cette tubulure, en ce que la paroi transversale d'obturation comporte une zone d'épaisseur réduite destinée à être perforée par cet embout perforateur, et en ce que l'une des jupes comporte intérieurement une première paroi cylindrique adjacente à la paroi transversale d'obturation et bordée à distance de celle-ci par une nervure en saillie radialement interne, en sorte de pouvoir s'adapter autour d'un premier format de goulot présentant un rebord en saillie radialement externe, et une seconde paroi cylindrique de plus grand diamètre raccordée à la première par une portée transversale d'appui et bordée à distance de celle-ci par une seconde nervure en saillie radialement interne, en sorte de pouvoir s'adapter autour d'un second format de goulot de plus grand diamètre que le premier et présentant un rebord en saillie radialement externe, cette même jupe comportant extérieurement une paroi globalement cylindrique adaptée à pénétrer dans le goulot d'un biberon.The invention provides for this purpose a device for connecting an enteral nutrition tube to a container containing a nutritive composition and provided with a neck, of the type comprising a transverse closure wall and a set of at least two coaxial elastic cylindrical skirts integral with the transverse obturation wall with which they form a plug, and which can each engage internally in the necks of containers having different predetermined formats, characterized in that it is formed of a fitting comprising this transverse obturation wall and this skirt, and of an independent perforating end-piece, known per se, mounted at one end of this tubing, in that the transverse obturation wall comprises an area of reduced thickness intended to be perforated by this perforating tip, and in that one of the skirts internally has a first cylindrical wall adjacent to the transverse obturating wall ation and bordered at a distance therefrom by a radially projecting rib, so as to be able to adapt around a first neck format having a radially projecting rim, and a second cylindrical wall of larger diameter connected to the first by a transverse bearing surface and bordered at a distance therefrom by a second rib projecting radially internally, so as to be able to adapt around a second format of neck of larger diameter than the first and having a radially external protruding rim, this same skirt externally comprising a generally cylindrical wall adapted to penetrate the neck of a bottle.

On appréciera que le fait que ce raccord soit indépendant du reste de la tubulure en permet une plus grande facilité de fabrication et de stockage stérile tout en permettant la mise en oeuvre de tubulures munies de perforateurs utilisables dans d'autres applications, ce qui en réduit le prix de revient.It will be appreciated that the fact that this connection is independent of the rest of the tubing allows greater ease of manufacture and sterile storage while allowing the use of tubing provided with perforators usable in other applications, which reduces cost price.

Des objets, caractéristiques et avantages de l'invention ressortent de la description qui suit, donnée à titre d'exemple non limitatif, en regard des dessins annexés sur lesquels :

  • la figure 1 est une vue en coupe axiale diamétrale d'un raccord selon l'invention, selon la ligne I-I de la figure 2,
  • la figure 2 en est une vue de dessous selon la flèche II de la figure 1,
  • la figure 3 est une version agrandie de la figure 1 montrant divers goulots de récipient susceptibles de recevoir le raccord ; et
  • la figure 4 est une vue latérale avec arrachement partiel d'une extrémité de tubulure de nutrition entérale munie d'un perforateur adapté à coopérer avec le raccord.
Objects, characteristics and advantages of the invention appear from the following description, given by way of nonlimiting example, with reference to the appended drawings in which:
  • FIG. 1 is a view in diametrical axial section of a connector according to the invention, along line II of FIG. 2,
  • FIG. 2 is a bottom view of it according to arrow II of FIG. 1,
  • Figure 3 is an enlarged version of Figure 1 showing various container necks capable of receiving the connector; and
  • Figure 4 is a side view with partial cutaway of one end of enteral nutrition tubing provided with a perforator adapted to cooperate with the connector.

Le raccord 1 représenté à titre d'exemple aux figures 1 à 3 comporte un jeu de plusieurs jupes coaxiales, élastiques, ici au nombre de deux (références 2 et 3), raccordées à une paroi transversale d'obturation 4 comportant une zone 5 d'épaisseur réduite, ici disposée dans l'axe X-X, cette zone est adaptée à être perforée par un embout perforateur, par exemple représenté sous la référence 6 à la figure 4, monté à une extrémité d'une tubulure 7 que ce raccord 1 est destiné à raccorder au goulot d'un récipient (non représenté) contenant une composition nutritive. Cette zone 5 est ici constituée par un perçage partiellement obturé (par exemple de diamètre égal à 4 mm).The connector 1 shown by way of example in FIGS. 1 to 3 comprises a set of several coaxial, elastic skirts, here two in number (references 2 and 3), connected to a transverse obturation wall 4 comprising an area 5 d 'reduced thickness, here arranged in the axis XX, this zone is adapted to be perforated by a perforating end piece, for example represented under the reference 6 in FIG. 4, mounted at one end of a tube 7 that this connector 1 is intended to connect to the neck of a container (not shown) containing a nutritive composition. This zone 5 is here constituted by a partially closed hole (for example with a diameter equal to 4 mm).

Les jupes 2 et 3 de ce raccord sont conformées de manière à pouvoir chacune s'engager, intérieurement ou extérieurement, sur des goulots 8A, 8B, 8C et 8D ayant des formats prédéterminés différents.The skirts 2 and 3 of this connector are shaped so that each can engage, internally or externally, on necks 8A, 8B, 8C and 8D having different predetermined formats.

Dans l'exemple considéré les jupes 2 et 3 sont disposées d'un même côté de la paroi transversale d'obturation 4, la jupe 2 étant située à l'intérieur de la jupe 3.In the example considered, the skirts 2 and 3 are arranged on the same side of the transverse closure wall 4, the skirt 2 being located inside the skirt 3.

La jupe 2, ou jupe interne, est munie extérieurement de nervures 10 de frottement décalées axialement grâce auxquelles cette jupe interne est adaptée à s'engager et se retenir intérieurement dans le goulot 8C et à s'y maintenir. Ce goulot 8C est par exemple un goulot cylindrique plastique à parois lisses dont est muni à ce jour un type de récipient conformé en poche souple.The skirt 2, or internal skirt, is provided externally with friction ribs 10 axially offset by which this internal skirt is adapted to engage and retain internally in the neck 8C and to be maintained there. This neck 8C is for example a cylindrical plastic neck with smooth walls which is provided to date with a type of container shaped flexible pouch.

Le diamètre extérieur de cette paroi est par exemple de 14,2 mm avec des nervures venant en saillie sur 0,5 mm.The outer diameter of this wall is for example 14.2 mm with ribs projecting over 0.5 mm.

La jupe 3, ou jupe externe, comporte intérieurement une première paroi cyindrique 11, adjacente à la paroi d'obturation 4 et bordée à distance de celle-ci par une nervure 12 en saillie interne grâce à laquelle cette première paroi peut venir coiffer un gouloit 8B muni d'un rebord 13 sous lequel vient s'engager ladite nervure 12. Le goulot 8B correpond de préférence au format standard des bouteilles adaptées à être fermées par une capsule métallique. Le diamètre interne de cette première paroi est dans ce cas de 26 mm.The skirt 3, or external skirt, internally comprises a first cylindrical wall 11, adjacent to the closure wall 4 and bordered at a distance therefrom by a rib 12 projecting internally thanks to which this first wall can come to cover a gully 8B provided with a rim 13 under which said rib 12 engages. The neck 8B preferably corresponds to the standard format of the bottles adapted to be closed by a metal cap. The internal diameter of this first wall is in this case 26 mm.

Cette jupe 3 comporte en outre, intérieurement, une seconde paroi cylindrique 14 de plus grand diamètre que la première, racordée à la première par une portée transversale d'appui 15, et bordée à distance de celle-ci par une seconde nervure 16 en saillie interne grâce à laquelle cette seconde paroi peut venir coiffer un goulot 8A muni d'un rebord 17 sous lequel vient se placer ladite nervure 16. Ce goulot 8A correspond de préférence au format normalisé des goulots de flaçons de perfusion. Il existe en effet des préparations nutritives conditionnées dans des récipients munis de tels goulots. Le diamètre interne de cette seconde paroi cylindrique est par exemple dans ce cas égal à 30,5 mm.This skirt 3 further comprises, internally, a second cylindrical wall 14 of larger diameter than the first, connected to the first by a transverse bearing surface 15, and bordered at a distance therefrom by a second projecting rib 16 internal thanks to which this second wall can come to cap a neck 8A provided with a flange 17 under which is placed said rib 16. This neck 8A preferably corresponds to the standardized format of the necks of perfusion bottles. There are indeed nutritious preparations packaged in containers fitted with such necks. The internal diameter of this second cylindrical wall is for example in this case equal to 30.5 mm.

De manière avantageuse cette jupe externe comporte extérieurement une paroi 18 globalement cylindrique adaptée à pénétrer dans le goulot 8D d'un récipient, par exemple un biberon. Pour faciliter la pénétration du raccord dans le biberon cette paroi externe 18 est légèrement effilée avec, dans l'exemple considéré, un diamètre qui diminue de 34 mm à proximité de la paroi transversale 4 à 33 mm à 23 mm de celle-ci.Advantageously, this external skirt externally has a generally cylindrical wall 18 adapted to penetrate in the 8D neck of a container, for example a bottle. To facilitate penetration of the connector into the bottle, this external wall 18 is slightly tapered with, in the example under consideration, a diameter which decreases by 34 mm near the transverse wall 4 to 33 mm to 23 mm thereof.

En combinaison avec cette paroi externe 18 est avantageusement prévue une paroi cylindrique 19 bordant radialement la paroi transversale d'obturation 4 tandis qu'une bride 20 en saillie radialement externe est ménagée longitudinalement entre les parois 18 et 19. Cette bride 20 est adaptée à être pressée axialement contre le goulot 8D par la portée transversale 21A d'une bague de serrage 21 associé à ce biberon, cernant latéralement la paroi transversale d'obturation 4.In combination with this external wall 18 is advantageously provided a cylindrical wall 19 radially bordering the transverse obturation wall 4 while a flange 20 projecting radially external is formed longitudinally between the walls 18 and 19. This flange 20 is adapted to be pressed axially against the neck 8D by the transverse surface 21A of a clamping ring 21 associated with this bottle, laterally encircling the transverse closure wall 4.

Il va de soi que la description qui précède n'a été proposée qu'à titre d'exemple illustratif non limitatif et que de nombreuses variantes peuvent être proposées sans sortir du cadre de l'invention. Ainsi par exemple, en fonction des formats des goulots sur lesquels ce raccord doit venir s'adapter, on peut prévoir des jupes complémentaires disposées à l'extérieur des jupes 2 et 3, ou du côté opposé par rapport à la paroi transversale d'obturation.It goes without saying that the above description has been offered only by way of nonlimiting illustrative example and that numerous variants can be proposed without departing from the scope of the invention. Thus, for example, depending on the formats of the necks on which this fitting must come to be adapted, it is possible to provide complementary skirts arranged outside of skirts 2 and 3, or on the opposite side with respect to the transverse obturation wall. .

Comme il ressort de la figure 4, le perforateur 8 ménagé à un extrémité de la tubulure en est généralement séparé par une chambre 22 de goutte à goutte, muni d'un embout de prise d'air 23. Dans l'embout perforateur 8 sont ménagés deux canaux longitudinaux 24 et 25 respectivement reliés à l'intérieur de la chambre 22 et l'embout 23.As can be seen from FIG. 4, the perforator 8 formed at one end of the tubing is generally separated from it by a drip chamber 22, provided with an air intake nozzle 23. In the perforator nozzle 8 are formed two longitudinal channels 24 and 25 respectively connected inside the chamber 22 and the end piece 23.

La matière constitutive du raccord est de tout type approprié compatible avec les exigences médicales.The material of the connector is of any suitable type compatible with medical requirements.

La paroi de la jupe interne équipée des nervures 10 est avantageusement tronconique tandis que, le cas échéant, la jupe externe peut comporter des perforations.The wall of the internal skirt equipped with the ribs 10 is advantageously frustoconical while, where appropriate, the external skirt may include perforations.
