Description

L'invention concerne un récipient de conditionnement de mélanges NO/N2 comprenant un corps principal formé d'aluminium ou d'un alliage d'aluminium, en particulier une bouteille de gaz de forme cylindrique, et son utilisation dans le traitement des vasoconstrictions pulmonaires chez l'adulte ou l'enfant.The invention relates to a NO / N 2 mixture conditioning vessel comprising a main body made of aluminum or an aluminum alloy, in particular a cylindrical gas cylinder, and its use in the treatment of pulmonary vasoconstrictions. in the adult or the child.

Les mélanges gazeux NO/N2 sont couramment utilisés pour traiter les vasoconstrictions pulmonaires chez l'adulte ou l'enfant, en particulier chez les nouveaux nés souffrant d'hypertension pulmonaire primitive ou chez les patients subissant une opération de chirurgie cardiaque.Gaseous NO / N 2 mixtures are commonly used to treat pulmonary vasoconstriction in adults or children, particularly in neonates with primary pulmonary hypertension or in patients undergoing cardiac surgery.

Ces mélanges NO/N2 sont classiquement conditionnés dans des bouteilles de gaz en acier. Typiquement, ces bouteilles contiennent de 100 à 1000 ppm en volume de NO et de l'azote (N2) pour le reste. Ces bouteilles ont habituellement une contenance en eau de 2 à 50 litres, ce qui permet d'y introduire une charge totale pouvant aller jusqu'à 15 m3 de mélange NO/N2.These NO / N 2 mixtures are conventionally packaged in steel gas cylinders. Typically, these bottles contain 100 to 1000 ppm by volume of NO and nitrogen (N 2 ) for the rest. These bottles usually have a water capacity of 2 to 50 liters, which allows to introduce a total load of up to 15 m 3 of NO / N 2 mixture.

Le conditionnement, c'est-à-dire la mise en bouteille de ces mélanges, se fait dans des centres de conditionnement de gaz.The packaging, that is to say the bottling of these mixtures, is done in gas conditioning centers.

Or, on a constaté en pratique une imprécision lors du conditionnement des mélanges gazeux NO/N2 dans ces bouteilles en acier. En effet, on a noté un écart entre le volume interne de chaque bouteille disponible pour le conditionnement du NO par rapport au volume théorique en eau de ces bouteilles ; cet écart est appelé ci-après « écart de contenance ».However, it has been found in practice imprecision during the conditioning of gas mixtures NO / N 2 in these steel bottles. Indeed, there was a difference between the internal volume of each bottle available for the conditioning of the NO with respect to the theoretical volume of water of these bottles; this difference is hereinafter referred to as the "capacity gap".

Cet écart de contenance n'a pas d'influence sur la teneur en NO finale mais se répercute sur la charge finale de la bouteille qui est alors soit supérieure, soit inférieure à la charge désirée, c'est-à-dire par rapport à la charge de consigne.This difference in capacity has no influence on the final NO content but has repercussions on the final charge of the bottle, which is then either greater or less than the desired load, that is to say with respect to the setpoint charge.

Toutefois, cet écart de contenance n'est pas négligeable puisque qu'il peut atteindre environ 5% de la charge totale en gaz de chaque bouteille.However, this difference in capacity is not negligible since it can reach about 5% of the total gas load of each bottle.

Par ailleurs, les récipients de conditionnement doivent en outre ne pas être de poids excessif et surtout résister à des chocs et à une pression gazeuse pouvant atteindre plusieurs centaines de bar, typiquement de 200 à 300 bar, ainsi qu'à la corrosion.In addition, the packaging containers must also not be overweight and especially withstand shocks and gas pressure of up to several hundred bar, typically 200 to 300 bar, and corrosion.

Le but de la présente invention est de résoudre ces problèmes, c'est-à-dire de minimiser ledit écart de contenance en obtenant une charge finale aussi proche que possible de la consigne de charge, c'est-à-dire un écart de l'ordre de +/- 1,5% ou inférieur, tout en proposant un récipient de conditionnement résistant aux chocs et aux hautes pressions, ainsi qu'à la corrosion, mais sans présenter un poids trop élevé.The object of the present invention is to solve these problems, that is to say to minimize said difference in capacity by obtaining a final load as close as possible to the load reference, that is to say a difference of order of +/- 1.5% or less, while offering a container packaging resistant to shocks and high pressures, as well as corrosion, but without presenting too much weight.

La solution de l'invention est un récipient de conditionnement de mélanges NO/N2 comprenant un corps principal comprenant un volume interne ayant une contenance comprise entre 2 et 30 litres et contenant un mélange NO/N2 à une pression supérieure à la pression atmosphérique, le corps principal étant formé d'un alliage d'aluminium, caractérisé en ce que le corps principal est formé d'un alliage d'aluminium comprenant majoritairement de l'aluminium, c'est-à-dire plus de 50% en masse, voire plus de 60% en masse, préférentiellement plus de 75% en masse, et une proportion massique de Cr entre 0,05 et 0,80%, de Cu entre 1 et 3%, de Pb d'au plus 100 ppm, de Zn entre 5 et 8%, et de Mg entre 1 et 3%.The solution of the invention is a NO / N 2 mixture conditioning container comprising a main body comprising an internal volume having a capacity of between 2 and 30 liters and containing a NO / N 2 mixture at a pressure greater than atmospheric pressure. , the main body being formed of an aluminum alloy, characterized in that the main body is formed of an aluminum alloy comprising predominantly aluminum, that is to say more than 50% by weight or even more than 60% by weight, preferably more than 75% by weight, and a mass proportion of Cr between 0.05 and 0.80%, Cu between 1 and 3%, Pb of not more than 100 ppm, Zn between 5 and 8%, and Mg between 1 and 3%.

Dans le cadre de la présente invention, il a été mis en évidence que l'écart de charge, c'est-à-dire l'imprécision de volume de charge, était en fait liée aux bouteilles utilisées pour conditionner les mélanges NO/N2. En effet, il a été remarqué que l'utilisation de bouteilles en acier ne permettait pas d'obtenir une précision de charge désirée mais qu'à l'inverse, l'utilisation de bouteilles en aluminium permettait d'obtenir la précision désirée.In the context of the present invention, it has been demonstrated that the load difference, that is to say the imprecision of the volume of charge, was in fact related to the bottles used to condition the NO / N mixtures. 2 . Indeed, it was noticed that the use of steel bottles did not allow to obtain a desired load accuracy but that, conversely, the use of aluminum bottles made it possible to obtain the desired precision.

Or, si le fait de réaliser les bouteilles en aluminium permet également d'apporter une relative légèreté, il a été constaté que l'alliage d'aluminium doit être choisi avec soin pour ne pas engendrer une fragilité trop importante des bouteilles. Cette fragilité peut être évitée ou minimisée en contrôlant notamment la composition de l'alliage d'aluminium choisie, c'est-à-dire la teneur en les différents éléments de l'alliage, en particulier celle en Mg, Cr, Cu et/ou Zn, mais aussi la teneur en plomb de l'alliage et accessoirement la taille des grains de l'alliage.However, if the fact of making the aluminum bottles also makes it possible to bring about a relative lightness, it has been found that the aluminum alloy must be chosen carefully so as not to cause excessive fragility of the bottles. This fragility can be avoided or minimized by controlling in particular the composition of the chosen aluminum alloy, that is to say the content of the various elements of the alloy, in particular that in Mg, Cr, Cu and / or Zn, but also the lead content of the alloy and incidentally the grain size of the alloy.

  • la Figure 1 schématise un récipient de gaz selon l'invention (vue en coupe) ; et
  • la Figure 2 schématise une installation de distribution de mélanges NO/N2 comprenant une bouteille de NO/N2 selon la Figure 1.
The invention will now be better understood thanks to the following description given with reference to the appended figures in which:
  • the Figure 1 schematizes a gas container according to the invention (sectional view); and
  • the Figure 2 schematizes a NO / N 2 mixture distribution plant comprising a bottle of NO / N 2 according to the Figure 1 .

La Figure 1 ci-jointe monte un mode de réalisation d'un récipient selon l'invention (vue en coupe), à savoir une bouteille de conditionnement de mélanges gazeux NO/azote qui se compose d'un corps principal 1 de forme générale cylindrique comprenant un étranglement ou col 2 au niveau duquel se trouve l'ouverture 5 de passage du gaz et, à son autre extrémité, d'un fond 3 plat sur lequel repose la bouteille lorsqu'elle est posée sur un support, tel le sol 6.The Figure 1 attached an embodiment of a container according to the invention (sectional view), namely a bottle of gas mixture NO / nitrogen mixture which consists of a main body 1 of generally cylindrical shape comprising a constriction or neck 2 at which is the opening 5 of the gas passage and at its other end, a flat bottom 3 on which the bottle rests when it is placed on a support, such as the ground 6.

Cette bouteille comprend un volume interne 7 ayant une contenance typique :

  • soit de 5 litres (en eau), un diamètre de 14 cm, et une hauteur de 63 cm.
  • soit de 20 litres (en eau), un diamètre de 21 cm, et une hauteur de 108 cm.
This bottle comprises an internal volume 7 having a typical capacity:
  • or 5 liters (in water), a diameter of 14 cm, and a height of 63 cm.
  • 20 liters (in water), a diameter of 21 cm, and a height of 108 cm.

Il est toutefois également possible d'avoir une bouteille de contenance inférieure, par exemple de 2 litres seulement, ou de dimensions différentesIt is however also possible to have a bottle of lower capacity, for example of only 2 liters, or of different dimensions

Un mélange NO/azote contenant jusqu'à 1000 ppm en volume de NO et d'azote pour le reste, par exemple de 225, 450 ou 800 ppm vol., est conditionné dans la bouteille à une pression de plus de 150 bar, par exemple de 180 bar.A NO / nitrogen mixture containing up to 1000 ppm by volume of NO and nitrogen for the remainder, for example 225, 450 or 800 ppm vol., Is packaged in the bottle at a pressure of more than 150 bar, by example of 180 bar.

Conformément à l'invention, le corps 1 de la bouteille est formé d'un alliage d'aluminium dont des exemples de compositions d'alliages A et B sont donnés dans le Tableau suivant. Tableau Eléments Proportion en masse Alliage A Proportion en masse Alliage B Pb < 30 ppm < 100 ppm Fe < 0,2 % < 0,12 % Si < 0,15 % < 0,1 % Cu 1.8 - 2.6 % 1,7 - 2,3 % Mn < 0,2 % < 0,05 % Mg 1.3 à 2.1 % 1,5 - 2,5 % Cr 0,15 à 0,25 % 0,15 à 0,25 % Zn 6.1 - 7.5 % 5,5 - 6,5 % Ti < 0,05 % < 0,1 % Zr < 0,05% / Bi / < 0,01 % Impuretés 0,15 % maxi Al 86.7-90.7% 87,9 - 91,2% According to the invention, the body 1 of the bottle is formed of an aluminum alloy, examples of alloy compositions A and B are given in the following Table. <U> Table </ u> elements Mass ratio Alloy A Mass ratio Alloy B Pb <30 ppm <100 ppm Fe <0.2% <0.12% Yes <0.15% <0,1% Cu 1.8 - 2.6% 1.7 - 2.3% mn <0.2% <0.05% mg 1.3 to 2.1% 1.5 - 2.5% Cr 0.15 to 0.25% 0.15 to 0.25% Zn 6.1 - 7.5% 5.5 - 6.5% Ti <0.05% <0,1% Zr <0.05% / Bi / <0.01% impurities 0,15% maximum al 86.7-90.7% 87.9 - 91.2%

En utilisant une bouteille avec corps 1 en un alliage d'aluminium, tel que donné notamment le Tableau précédent, il est possible de minimiser l'écart de contenance susmentionné en obtenant une charge finale aussi proche que possible de la consigne de charge, c'est-à-dire un écart de l'ordre de +/- 1,5% ou inférieur, tout en ayant un récipient résistant aux chocs, aux hautes pressions et à la corrosion.By using a bottle with a body 1 made of an aluminum alloy, such as given in particular in the preceding table, it is possible to minimize the difference in the aforementioned capacity by obtaining a final charge as close as possible to the charging setpoint. that is to say a deviation of the order of +/- 1.5% or less, while having a container resistant to shocks, high pressures and corrosion.

La Figure 2 ci-annexée illustre un mode de réalisation d'une installation de distribution de mélanges NO/N2 comprenant un ventilateur 10 comportant un circuit patient 11 reliant le ventilateur 10 à une interface 14 patient. Le circuit patient 11 est alimenté en gaz par un récipient 1 selon la Figure 1 dont la composition est par exemple celle de l'alliage A ou B du tableau précédent.The Figure 2 attached hereto illustrates an embodiment of a NO / N 2 mixture dispensing installation comprising a fan 10 comprising a patient circuit 11 connecting the fan 10 to a patient interface 14. The patient circuit 11 is supplied with gas by a receptacle 1 according to the Figure 1 whose composition is for example that of the alloy A or B of the preceding table.

Le ventilateur 10 alimente donc en gaz respiratoire enrichi en NO, un circuit respiratoire ou circuit patient 11 à deux branches, c'est-à-dire avec une branche inspiratoire 12 et une branche expiratoire 13. La branche inspiratoire 12 est conçue pour acheminer un gaz respiratoire, par exemple de l'air, de l'air enrichi en oxygène, de l'oxygène ou un mélange azote/O2, du ventilateur 10 jusqu'au patient 15, alors que la branche expiratoire 13 est conçue pour acheminer le gaz expiré par le patient 15, donc riches en CO2, jusqu'au ventilateur 10.The ventilator 10 thus supplies with respiratory gas enriched in NO, a respiratory circuit or patient circuit 11 with two branches, that is to say with an inspiratory branch 12 and a branch expiratory 13. The inspiratory branch 12 is designed to convey a breathing gas, for example air, oxygen-enriched air, oxygen or a nitrogen / O 2 mixture, from the ventilator 10 to the patient 15 , while the exhalation branch 13 is designed to convey the exhaled gas by the patient 15, thus rich in CO 2 , to the ventilator 10.

Au niveau du patient 15, l'administration du gaz se fait au moyen d'une interface patient 14, par exemple un masque respiratoire, une sonde ou une canule trachéale ou tout autre dispositif d'administration de gaz adapté.At the level of the patient 15, the administration of the gas is by means of a patient interface 14, for example a respiratory mask, a probe or a tracheal cannula or any other suitable gas delivery device.

Le ventilateur 1 est alimenté avec un gaz contenant de l'oxygène, par exemple de l'air (teneur en O2 de 21 % en volume), de l'air enrichi en oxygène (teneur en O2 > 21 % en volume) ou de l'oxygène pur (100% O2).The fan 1 is supplied with a gas containing oxygen, for example air (O 2 content of 21% by volume), air enriched with oxygen (O 2 content> 21% by volume). or pure oxygen (100% O 2 ).

Le gaz contenant de l'oxygène est issu d'une source de gaz 17, telle une ou plusieurs bouteilles de gaz, un mélangeur de gaz au sein duquel est opéré par exemple un mélange d'air et d'oxygène, ou une ou plusieurs canalisations de gaz véhiculant un ou plusieurs gaz, par exemple une canalisation véhiculant de l'oxygène provenant d'une unité de production d'oxygène, telle une unité à pression modulée (PSA), ou d'une unité de stockage d'oxygène, telle un réservoir tampon ou de stockage.The oxygen-containing gas comes from a gas source 17, such as one or more gas cylinders, a gas mixer in which is operated for example a mixture of air and oxygen, or one or more gas pipelines conveying one or more gases, for example a pipe carrying oxygen from an oxygen production unit, such as a modulated pressure unit (PSA), or an oxygen storage unit, such as a buffer or storage tank.

Comme déjà dit, le gaz riche en oxygène est délivré par le ventilateur 10 dans la branche inspiratoire 12 du circuit patient 11.As already stated, the oxygen-rich gas is delivered by the ventilator 10 into the inspiratory branch 12 of the patient circuit 11.

Par ailleurs, un dispositif 16 de distribution de NO est relié fluidiquement à ladite branche inspiratoire 12 du circuit patient 11 pour y délivrer, via une ligne d'alimentation 18, un mélange NO/N2 par exemple formé de 400, 800 ou 1000 ppmv de NO et d'azote pour le reste.Furthermore, a NO distribution device 16 is fluidly connected to said inspiratory branch 12 of the patient circuit 11 to deliver, via a feed line 18, a NO / N 2 mixture, for example formed of 400, 800 or 1000 ppmv. NO and nitrogen for the rest.

Le dispositif 16 de distribution de NO est lui-même alimenté en mélange NO/N2, via une ligne d'amenée de gaz 19, par un récipient 1 de NO/N2 faisant partie d'un système de stockage et de distribution selon l'invention.The NO distribution device 16 is itself fed with a NO / N 2 mixture, via a gas supply line 19, with a container 1 of NO / N 2 forming part of a storage and distribution system according to the invention.

Le récipient de NO/N2 est une bouteille de gaz en alliage d'aluminium (alliage A ou B par exemple) de contenant de 2, 5 ou 11 litres (équivalent en eau), équipée d'un robinet à détendeur intégré, de préférence protégé par un capotage de protection contre les chocs. Le robinet à détendeur intégré, encore appelé « RDI » permet de contrôler la sortie du gaz du récipient 1 et sa pression de sortie. Des organes de commande permettent de contrôler la libération du gaz et par ailleurs de régler le niveau de pression de sortie.The NO / N 2 container is an aluminum alloy gas cylinder (alloy A or B for example) containing 2, 5 or 11 liters (water equivalent), equipped with a built-in pressure regulating valve, preferably protected by a rollover protection hood. The integrated regulator valve, also called "RDI" allows to control the gas outlet of container 1 and its outlet pressure. Controllers control the release of the gas and also adjust the output pressure level.

Une telle installation est adaptée au traitement avec administration de NO par inhalation, des vasoconstrictions pulmonaires ou de l'hypertension pulmonaire chez un patient 15, qui peut être un adulte, un enfant ou un nouveau né.Such an installation is suitable for treatment with inhaled NO administration, pulmonary vasoconstriction or pulmonary hypertension in a patient 15, who may be an adult, a child or a newborn.

Plus précisément, le mélange gazeux NO/N2 véhiculé jusqu'au patient 15 par le circuit patient 11 et distribué au moyen de l'interface 14, est particulièrement recommandé pour traiter un nouveau-né souffrant d'hypertension pulmonaire primitive ou un adulte, un enfant ou un nouveau-né devant subir, subissant ou ayant subi une opération de chirurgie cardiaque.More specifically, the NO / N 2 gas mixture conveyed to the patient 15 by the patient circuit 11 and distributed by means of the interface 14, is particularly recommended for treating a newborn with primary pulmonary hypertension or an adult. a child or newborn who has to undergo, undergoing or having undergone cardiac surgery.
