Abstract

Gas container for supply of decontaminated gas provided with a device for regulating flow rate or gas pressure of exiting gas and at least one penetrating tube with a filtration part to effect a microbial sterilization, the upper part of the tube being linked to the regulator.

Description

La présente invention concerne le domaine de la stérilisation et de laThe present invention relates to the field of sterilization and

décontamination des gaz.decontamination of gases.

Elle concerne donc notamment le domaine des dispositifs stérilisants ou dits d'abattement microbien appliqués aux gaz ou liquides cryogéniques.  It therefore relates in particular to the field of sterilizing devices or so-called microbial abatement applied to gases or cryogenic liquids.

On sait que selon un vocabulaire commun à tous la notion de stérilisation suppose d'obtenir en aval du dispositif utilisé un abattement d'au moins six Log de la concentration microbienne par rapport à la concentration amont entrante.  It is known that according to a vocabulary common to all the notion of sterilization assumes to obtain downstream of the device used an abatement of at least six log of the microbial concentration with respect to the incoming upstream concentration.

La notion d'abattement microbien pour sa part réalise un abattement moins poussé de cette concentration microbienne i.e inférieure à six Log.  The notion of microbial abatement for its part achieves a less extensive reduction of this microbial concentration i.e less than six log.

Il est maintenant bien connu que la qualité bactériologique des gaz, et notamment des gaz pour application alimentaire ou médicale, prend une importance croissante.  It is now well known that the bacteriological quality of gases, and especially gases for food or medical use, is becoming increasingly important.

Il s'agit notamment d'air, de CO2, de N2O, de l'oxygène, d'azote, de leurs mélanges etc...  These include air, CO2, N2O, oxygen, nitrogen, their mixtures etc ...

Il semble assez clairement établi maintenant que les gaz ainsi stockés sont potentiellement porteurs et/ou vecteurs de micro-organismes, par le fait même que rien dans leurs procédés de fabrication ou de distribution n'est prévu ou adapté pour les rendre stériles.  It seems quite clear now that the gases thus stored are potentially carriers and / or vectors of microorganisms, by the very fact that nothing in their manufacturing or distribution processes is planned or adapted to make them sterile.

Un des objectifs de la présente invention est alors de pouvoir proposer un système interne à une bouteille ou stockage de gaz permettant de délivrer un gaz stérile ou à tout le moins décontaminé.  One of the objectives of the present invention is then to be able to propose an internal system to a bottle or gas storage for delivering a sterile gas or at least decontaminated.

A cet effet, l'invention a pour objet un stockage de gaz destiné à fournir un gaz décontaminé, le stockage étant muni d'un dispositif de réglage du débit ou de la pression sortant du stockage, et d'au moins un tube plongeant muni d'un premier organe de filtration réalisant un abattement microbien, la partie supérieure du tube étant solidaire dudit dispositif de réglage.  For this purpose, the subject of the invention is a gas storage intended to supply a decontaminated gas, the storage being provided with a device for adjusting the flow rate or the pressure exiting the storage, and at least one dip tube provided with a first filter member performing a microbial abatement, the upper part of the tube being integral with said adjustment device.

Le stockage suivant l'invention peut comporter une ou plusieurs des caractéristiques suivantes, prise(s) isolément ou selon toutes les combinaisons techniquement possibles: - le stockage est muni d'une entrée de gaz destiné à permettre son remplissage et d'un second organe de filtration interne au stockage apte à filtrer le gaz entrant dans le stockage.  The storage according to the invention may comprise one or more of the following characteristics, taken in isolation or in any technically possible combination: the storage is provided with a gas inlet intended to allow its filling and a second organ internal storage filtration capable of filtering the gas entering the storage.

- le second organe de filtration est disposé sur un second tube plongeant solidaire de ladite entrée de gaz.  - The second filter member is disposed on a second dip tube integral with said gas inlet.

- le second organe de filtration permet une filtration dite grossière, des organismes de taille supérieure à 1 pm, tandis que le premier organe de filtration permet une filtration dite fine, des organismes de taille supérieure à 0,02 voire 0,01 pm.  - The second filter member allows a so-called coarse filtration, organisms larger than 1 micron, while the first filter member allows so-called fine filtration, organisms larger than 0.02 or 0.01 pm.

- le second organe de filtration comporte un filtre de nature différente de celle du premier organe de filtration.  the second filtering member comprises a filter of a different nature from that of the first filtering member.

- le second organe de filtration comporte un filtre adsorbeur d'eau apte à limiter la prolifération des micro-organismes dans le stockage.  - The second filter member comprises a water adsorber filter capable of limiting the proliferation of microorganisms in the storage.

- ledit dispositif de réglage permet le maintient en toute circonstance d'une pression positive dans le stockage (en d'autres termes: le stockage est vide pour l'utilisateur mais il y reste une certaine pression -par exemple 3 ou 4 bars-permettant d'une part d'éviter les retours de pollution dans le stockage, et d'autre part d'éviter les entrées d'air).  said adjustment device makes it possible to maintain a positive pressure in the storage under all circumstances (in other words: the storage is empty for the user but there remains a certain pressure therefor, for example 3 or 4 bar on the one hand to avoid the return of pollution in the storage, and on the other hand to avoid the entries of air).

- selon un mode avantageux de mise en oeuvre de l'invention, le premier organe de filtration met en oeuvre un filtre rigide en inox ou céramique.  - According to an advantageous embodiment of the invention, the first filter member implements a rigid filter stainless steel or ceramic.

- le dispositif de réglage est un robinet ou un mano-détendeur.  the adjustment device is a tap or a pressure regulator.

- le second tube plongeant est solidaire du dispositif de réglage.  the second dip tube is integral with the adjusting device.

- le dispositif de réglage est muni d'un clapet anti-retour sur l'une ou chacune des entrée/sortie de gaz.  - The adjustment device is provided with a non-return valve on one or each gas inlet / outlet.

Un exemple de mise en oeuvre de l'invention va maintenant être décrit, en regard de la figure unique annexée, qui est une vue partielle et en coupe de la partie supérieure d'une bouteille de stockage de gaz conforme à l'invention.  An exemplary implementation of the invention will now be described, with reference to the single appended figure, which is a partial view in section of the upper part of a gas storage bottle according to the invention.

On reconnaît sur la figure la partie supérieure d'une bouteille de gaz 3, munie en sa partie supérieure d'un robinet ou détendeur 1.  The figure shows the upper part of a gas cylinder 3, provided at its upper part with a valve or expander 1.

Les entrée/sortie 2 et 6 (munies chacune sur la figure d'un clapet antiretour) permettent respectivement le remplissage de la bouteille en gaz et la sortie de gaz de la bouteille.  The inlet / outlet 2 and 6 (each provided in the figure with a check valve) respectively allow the filling of the gas bottle and the gas outlet of the bottle.

Comme on le visualise bien sur la figure, le stockage est muni de deux tubes plongeants 7 et 8, tous deux solidaires du dispositif 1 de réglage de débit: - le tube plongeant 7 est solidaire de l'entrée de gaz et est muni d'un organe de filtration grossière 4; - le tube plongeant 8 est solidaire de la sortie de gaz et est muni d'un organe de filtration fine 5.  As is clearly shown in the figure, the storage is provided with two plunger tubes 7 and 8, both integral with the flow control device 1: the plunger tube 7 is integral with the gas inlet and is provided with a coarse filtering member 4; - The dip tube 8 is integral with the gas outlet and is provided with a fine filter member 5.

A titre illustratif, on pourra utiliser pour chacun des organes 4 et 5 les matériaux suivants: des matériaux métalliques (poreux inox, laiton...) , des fibres de verre, de céramique, des fibres synthétiques etc...  By way of illustration, it is possible to use for each of the members 4 and 5 the following materials: metallic materials (porous stainless steel, brass, etc.), glass fibers, ceramic fibers, synthetic fibers, etc.

On s'attachera bien entendu à privilégier des matériaux compatibles avec les gaz utilisés (par exemple à caractère non inflammable pour utilisation avec l'oxygène et le protoxyde d'azote).  Of course, preference will be given to materials that are compatible with the gases used (for example of non-flammable nature for use with oxygen and nitrous oxide).

On préférera à titre d'organe de filtration 5 un filtre à caractère rigide (par exemple en métal ou céramique) plutôt qu'un filtre en Téflon qui nécessite une grande stabilité de débits et qui de ce fait, résiste difficilement à des à-coups de pression et a tendance à relarguer les éléments qu'il avait précédemment retenus.  It is preferable as filtering member 5 a rigid character filter (for example metal or ceramic) rather than a Teflon filter which requires a great stability of flows and which, therefore, withstands hard jolts pressure and tends to relinquish the elements that he had previously retained.
