Definitions

  • the invention relates to a gas distribution assembly, in particular for medical gases, comprising a gas bottle, a valve block fixed to the gas bottle and a protective cover arranged around said valve block, said valve block comprising an indicator device.
  • pressure such as a pressure gauge, or a device indicating the content of the bottle, such as a range indicating device, which is housed in the upper part of the protective cowling and preferably a flywheel in front of the cowling.
  • Industrial and medical gases are commonly packaged in gas containers, typically gas cylinders, equipped with a valve block, with or without an integrated regulator, namely a simple valve of the open / closed type or a valve with integrated regulator, also called RDI, allowing to control flow and pressure of the delivered gas.
  • a valve block with or without an integrated regulator, namely a simple valve of the open / closed type or a valve with integrated regulator, also called RDI, allowing to control flow and pressure of the delivered gas.
  • RDI valve with integrated regulator
  • a protective cover forming a protective shell around said valve block.
  • a cowling is commonly called a "hat”.
  • bottle / cap / tap assembly to be hung on a support, such as a hospital bed bar, a stretcher, a rod or hanging bracket for an emergency vehicle, for example a SAMU or similar unit, it is usual to fit on the hat, a fixed or mobile attachment system, in particular pivoting.
  • a support such as a hospital bed bar, a stretcher, a rod or hanging bracket for an emergency vehicle, for example a SAMU or similar unit
  • the cowling In order to facilitate the transport and the handling of the bottle / valve block / cowling assembly, it is customary to provide the cowling with a carrying handle which, in general, overcomes it and allows it to be carried manually by one hand by the users. .
  • a pressure indicator device such as a pressure gauge on one of the gas passages passing through the valve block.
  • this pressure indicator device in the lower part of the valve, due to technical constraints, in particular the fact that the passage of gas subjected to the pressure of the bottle is located in the lower part of the valve, which means that it is often difficult or difficult to read the pressure indicated by the pressure indicator device and is often a source of reading errors.
  • a rotary flywheel is often arranged on the valve block on internal control units of the valve block.
  • the problem which arises is to improve the comfort of reading of the pressure indicator device fitted to a valve block protected by a protective cover for a gas bottle while avoiding the aforementioned drawbacks, and preferably also allowing a easy operation of the rotary wheel controlling the gas flow.
  • the solution of the invention is a gas distribution assembly comprising a gas bottle, a valve block fixed to the gas bottle and a protective cover arranged around said valve block, said valve block comprising a pressure indicator device, such as a pressure gauge, or the contents of the bottle and a rotary flywheel, operable by an operator, controlling the gas flow, characterized in that the protective cover comprises a first opening arranged at the top of the protective cover and at the within which is housed the pressure indicator device or the contents of the bottle.
  • the invention further relates to the use of a gas distribution assembly according to the invention for storing or distributing a gas or gas mixture, preferably a medical gas or gas mixture.
  • a gas or gas mixture is chosen from oxygen, air, N 2 O / O 2 , He / O 2 , NO / nitrogen
  • the Figure 1 presents an embodiment of a rigid protective cover 1, commonly called a "cap”, arranged around a valve block 12 (not entirely visible), namely a valve with or without an integrated regulator, itself fixed to the neck of a gas cylinder 2, said protective cover 1 being provided with a carrying handle 5 according to the present invention.
  • the gas cylinder 2 typically has a cylindrical steel body and a size between 10 and 150 cm, and a capacity of 0.5 to 20 liters (in water equivalent).
  • the protective cover 1 makes it possible to protect the valve block against shocks, whether the valve block 12 is of the type with integrated regulator or RDI, or of the type without integrated regulator, typically a valve of the RDI type.
  • the fixing around the valve block 12 on the neck of the gas bottle 2 is done by screwing.
  • the protective cowling 1 comprises a cowling body forming a protective shell around an internal volume dimensioned to receive the valve block 12, and a carrying handle 5 designed to be taken in hand by a user.

Description

L'invention porte sur un ensemble de distribution de gaz, notamment de gaz médicaux, comprenant une bouteille de gaz, un bloc robinet fixé sur la bouteille de gaz et un capotage de protection agencé autour dudit bloc robinet, ledit bloc robinet comprenant un dispositif indicateur de pression, tel manomètre, ou un dispositif indicateur du contenu de la bouteille, tel un dispositif indicateur d'autonomie, venant se loger dans la partie supérieure du capotage de protection et préférentiellement un volant en façade du capotage.The invention relates to a gas distribution assembly, in particular for medical gases, comprising a gas bottle, a valve block fixed to the gas bottle and a protective cover arranged around said valve block, said valve block comprising an indicator device. pressure, such as a pressure gauge, or a device indicating the content of the bottle, such as a range indicating device, which is housed in the upper part of the protective cowling and preferably a flywheel in front of the cowling.

Les gaz industriels et médicaux sont couramment conditionnés dans des récipients de gaz, typiquement des bouteilles de gaz, équipés d'un bloc robinet, avec ou sans détendeur intégré, à savoir un robinet simple de type ouvert/fermé ou un robinet à détendeur intégré, encore appelé RDI, permettant de contrôler débit et pression du gaz délivré.Industrial and medical gases are commonly packaged in gas containers, typically gas cylinders, equipped with a valve block, with or without an integrated regulator, namely a simple valve of the open / closed type or a valve with integrated regulator, also called RDI, allowing to control flow and pressure of the delivered gas.

Afin de protéger ce bloc robinet, il est courant d'agencer au niveau du col de la bouteille de gaz et autour dudit bloc robinet, un capotage de protection formant coque protectrice autour dudit bloc robinet. Un tel capotage est couramment appelé « chapeau ».In order to protect this valve block, it is common to arrange at the neck of the gas bottle and around said valve block, a protective cover forming a protective shell around said valve block. Such a cowling is commonly called a "hat".

Par ailleurs, pour permettre d'accrocher l'ensemble bouteille/chapeau/robinet à un support, tel un barreau de lit d'hôpital, un brancard, une tringle ou support d'accrochage d'un véhicule d'urgence, par exemple une unité de SAMU ou analogue, il est usuel d'aménager sur le chapeau, un système d'accrochage fixe ou mobile, notamment pivotant.In addition, to allow the bottle / cap / tap assembly to be hung on a support, such as a hospital bed bar, a stretcher, a rod or hanging bracket for an emergency vehicle, for example a SAMU or similar unit, it is usual to fit on the hat, a fixed or mobile attachment system, in particular pivoting.

Afin de faciliter le transport et les manipulations de l'ensemble bouteille/bloc robinet/capotage, il est usuel de doter le capotage d'une poignée de transport qui, en général, le surmonte et permet son portage manuel à une main par les utilisateurs.In order to facilitate the transport and the handling of the bottle / valve block / cowling assembly, it is customary to provide the cowling with a carrying handle which, in general, overcomes it and allows it to be carried manually by one hand by the users. .

Des capotages de ce type sont décrits notamment par les documents EP-A-629812 , DE-A-10057469 , US-A-2004/020793 et EP-A-2586481 .Rollovers of this type are described in particular in the documents EP-A-629812 , DE-A-10057469 , US-A-2004/020793 and EP-A-2586481 .

Afin de contrôler la pression du gaz, il est courant de fixer un dispositif indicateur de pression, tel un manomètre sur un des passages de gaz traversant le bloc robinet.In order to control the gas pressure, it is common to fix a pressure indicator device, such as a pressure gauge on one of the gas passages passing through the valve block.

Or, le positionnement de ce dispositif indicateur de pression en partie basse du robinet, du fait de contraintes techniques, notamment du fait que le passage de gaz soumis à la pression de la bouteille est situé en partie basse du robinet, fait qu'il est souvent difficile ou peu aisé de lire la pression indiquée par le dispositif indicateur de pression et est souvent source d'erreurs de lecture.However, the positioning of this pressure indicator device in the lower part of the valve, due to technical constraints, in particular the fact that the passage of gas subjected to the pressure of the bottle is located in the lower part of the valve, which means that it is often difficult or difficult to read the pressure indicated by the pressure indicator device and is often a source of reading errors.

En outre, pour contrôler le débit du gaz délivré, c'est-à-dire autoriser ou interdire le cheminement du gaz dans le bloc robinet et donc une sortie de gaz dudit bloc, on agence souvent sur le bloc robinet, un volant rotatif agissant sur des organes de contrôle internes au bloc robinet.In addition, to control the flow of the gas delivered, that is to say to authorize or prohibit the flow of gas in the valve block and therefore a gas outlet from said block, a rotary flywheel is often arranged on the valve block on internal control units of the valve block.

Or, là encore, du fait de l'utilisation d'un capotage de protection entourant le bloc robinet, il est souvent difficile ou peu aisé pour l'utilisateur de manœuvrer le volant rotatif.However, here again, due to the use of a protective cover surrounding the valve block, it is often difficult or not easy for the user to operate the rotary flywheel.

Au vu de cela, le problème qui se pose est d'améliorer le confort de lecture du dispositif indicateur de pression équipant un bloc robinet protégé par un capotage de protection pour bouteille de gaz en évitant les inconvénients susmentionnés, et préférentiellement de permettre par ailleurs une manœuvre aisée du volant rotatif contrôlant le débit de gaz.In view of this, the problem which arises is to improve the comfort of reading of the pressure indicator device fitted to a valve block protected by a protective cover for a gas bottle while avoiding the aforementioned drawbacks, and preferably also allowing a easy operation of the rotary wheel controlling the gas flow.

Le capotage de protection 1 permet de protéger le bloc robinet contre les chocs, que le bloc robinet 12 soit du type avec détendeur intégré ou RDI, ou du type sans détendeur intégré, typiquement un robinet de type RDI. La fixation autour du bloc de robinet 12 sur le col de la bouteille de gaz 2 se fait par vissage.The protective cover 1 makes it possible to protect the valve block against shocks, whether the valve block 12 is of the type with integrated regulator or RDI, or of the type without integrated regulator, typically a valve of the RDI type. The fixing around the valve block 12 on the neck of the gas bottle 2 is done by screwing.

La poignée de portage 5 est formée d'un matériau rigide, tel un polymère ou un métal ou alliage métallique, et est portée par un ou plusieurs montants-supports 13 reliant mécaniquement le corps de capotage à la poignée de portage 5. La poignée de portage 5 est généralement agencée horizontalement, c'est-à-dire perpendiculairement ou quasi-perpendiculairement par rapport à l'axe vertical de la bouteille 2 et du capotage 1. La poignée de portage 5 a une forme longiligne, qu'elle soit rectiligne ou incurvée, typiquement une longueur inférieure à 20 cm, typiquement de 6 à 15 cm.The carrying handle 5 is formed from a rigid material, such as a polymer or a metal or metal alloy, and is carried by one or more support posts 13 connecting mechanically the casing body to the carrying handle 5.

De même, les montants-supports 13 peuvent être formés d'un matériau plastique, comme le corps du capotage 1, mais aussi en alliage d'aluminium ou tout autre matériau métallique. Ils peuvent être fixés à la poignée 5 par vissage ou soudage, par exemple, ou formés d'une seule pièce.Likewise, the support uprights 13 can be formed from a plastic material, such as the body of the cowling 1, but also from aluminum alloy or any other metallic material. They can be fixed to the handle 5 by screwing or welding, for example, or formed in one piece.

Le capotage de protection 1 présente par ailleurs des ouvertures 11, 14 donnant accès au bloc robinet 12 situé dans le volume interne du corps de capotage 1.The protective cowling 1 also has openings 11, 14 giving access to the valve block 12 located in the internal volume of the cowling body 1.

Plus précisément, une première ouverture 11 est aménagée au niveau de la partie supérieure la, encore appelée partie haute, du capotage de protection 1, au sein de laquelle vient se loger un dispositif indicateur de pression, tel un manomètre 4, soit à aiguille, soit électronique, ou du contenu de la bouteille, tel un dispositif indicateur d'autonomie. La partie inférieure 1b, encore appelée partie basse, du capotage 1 est située au niveau de la bouteille 2.More specifically, a first opening 11 is arranged at the upper part 1a, also called the upper part, of the protective cover 1, within which is housed a pressure indicator device, such as a manometer 4, or with a needle, either electronic, or the contents of the bottle, such as a device indicating autonomy. The lower part 1b, also called the lower part, of the cowling 1 is located at the level of the bottle 2.

A des fins de simplification, dans le reste de la description, on parlera de dispositif indicateur de pression mais les explications données s'appliquant stricto sensu à un dispositif indicateur du contenu de la bouteille, tel un dispositif indicateur d'autonomie, qui se substituerait au dispositif indicateur de pression.For the sake of simplification, in the remainder of the description, we will speak of a pressure indicator device but the explanations given apply strictly speaking to a device indicating the content of the bottle, such as a device indicating autonomy, which would replace pressure indicator device.

Par ailleurs, le capotage de protection 1 comprend une deuxième ouverture 14 aménagée en façade du capotage de protection 1, au sein de laquelle vient se loger le volant rotatif 6 contrôlant le débit du gaz traversant le bloc robinet 12.Furthermore, the protective cowling 1 comprises a second opening 14 arranged in front of the protective cowling 1, within which is housed the rotary flywheel 6 controlling the flow of gas passing through the valve block 12.

De préférence, l'axe AA du dispositif indicateur de pression, c'est-à-dire du manomètre 4, l'axe BB du volant rotatif 6 et l'axe CC de la bouteille 2 sont coplanaires. Avantageusement, l'axe AA du dispositif indicateur de pression 4 et l'axe BB du volant rotatif 6 forment un angle α compris entre 0° et 90°, de préférence d'au moins 30°, par exemple entre 45° et 85°, comme illustré en Figures 2 et 3.Preferably, the axis AA of the pressure indicator device, that is to say of the pressure gauge 4, the axis BB of the rotary flywheel 6 and the axis CC of the bottle 2 are coplanar. Advantageously, the axis AA of the pressure indicator device 4 and the axis BB of the rotary flywheel 6 form an angle α of between 0 ° and 90 °, preferably at least 30 °, for example between 45 ° and 85 ° , as illustrated in Figures 2 and 3 .

Selon le mode de réalisation schématisé en Figures 1 à 3, le capotage de protection 1 comprend une surface plane 10 au niveau sa partie supérieure la, c'est-à-dire en haut de capotage 1, au sein de laquelle surface plane 10 est aménagée la première ouverture 11.According to the embodiment shown schematically in Figures 1 to 3 , the protective covering 1 comprises a flat surface 10 at its upper part 1a, that is to say at the top of the covering 1, within which the flat opening 10 is formed the first opening 11.

La surface plane 10 constitue en fait une face oblique par rapport à l'axe de la bouteille 2. De préférence, la surface plane 10 est perpendiculaire à l'axe AA du manomètre 4, comme schématisé en Figure 3.The planar surface 10 in fact constitutes an oblique face with respect to the axis of the bottle 2. Preferably, the planar surface 10 is perpendicular to the axis AA of the pressure gauge 4, as shown schematically in Figure 3 .

Selon le mode de réalisation considéré, le dispositif indicateur de pression 4 est agencé dans la première ouverture 11 aménagée dans la surface plane 10 de manière à ce que sa vitre supérieure affleure au niveau de ladite surface plane 10, ou soit légèrement en retrait au sein du logement formé par la première ouverture 11 par rapport à ladite surface plane 10 ou encore soit, à l'inverse, légèrement en saillie vers l'extérieur par rapport à la surface plane 10.According to the embodiment considered, the pressure indicator device 4 is arranged in the first opening 11 arranged in the flat surface 10 so that its upper window is flush with the said flat surface 10, or is slightly recessed within of the housing formed by the first opening 11 relative to said planar surface 10 or alternatively either, slightly projecting outwardly relative to the planar surface 10.

Le dispositif indicateur de pression 4 peut être fixé au corps du bloc robinet situé dans le volume interne du capotage 1 ou au capotage.The pressure indicator device 4 can be fixed to the body of the valve block located in the internal volume of the cowling 1 or to the cowling.

Un tel agencement du dispositif indicateur de pression 4, c'est-à-dire du manomètre, en position haute et en façade du capotage 1, avec de préférence sa vitre de lecture inclinée de manière à former un angle donné par rapport à l'axe CC de la bouteille 2, permet de faciliter considérablement à l'utilisateur la lecture de pression délivrée par le dispositif indicateur de pression ou manomètre 4 qu'il soit à aiguille ou électronique.Such an arrangement of the pressure indicator device 4, that is to say of the pressure gauge, in the high position and in front of the cowling 1, preferably with its reading window inclined so as to form a given angle relative to the axis CC of the bottle 2, makes it considerably easier for the user to read the pressure delivered by the pressure indicator or pressure gauge device 4, whether it be a needle or an electronic device.

En outre, le fait de placer le volant rotatif manœuvrable par l'utilisateur en façade 1c du capotage 1, permet une manœuvre aisée du volant rotatif contrôlant le débit de gaz.In addition, the fact of placing the rotary flywheel maneuverable by the user on the front panel 1c of the cowling 1, allows easy operation of the rotary flywheel controlling the gas flow rate.

Par ailleurs, le bloc robinet 12 comprend également un raccord de remplissage 16, (cf. Fig. 3) situé en face arrière et accessible via une troisième ouverture (non visible sur les Figures) aménagée dans la face arrière du capotage 1, lequel raccord de remplissage sert à introduire du gaz dans la bouteille 2 lorsque celle-ci est vide ou presque vide, ainsi qu'un raccord de sortie de gaz sous pression 8, agencé en face latérale du capotage (voir Fig. 3) au sein d'une quatrième ouverture 15 pratiquée dans le corps du capotage 1.Furthermore, the valve block 12 also includes a filling connection 16, (cf. Fig. 3 ) located on the rear face and accessible via a third opening (not visible in the Figures) arranged in the rear face of the cowling 1, which filling connection is used to introduce gas into the bottle 2 when the latter is empty or almost empty, as well as a pressurized gas outlet connector 8, arranged opposite the cover (see Fig. 3 ) within a fourth opening 15 made in the body of the cowling 1.

Afin de permettre l'accroche ou l'arrimage de l'ensemble bouteille/bloc robinet/capotage à un support, tel un barreau de lit d'hôpital ou de brancard, le capotage de protection 1 comprend, du côté de sa face arrière, un dispositif d'accrochage 9 pivotant, entre une position totalement repliée, dite « de repos » (schématisé en Figure 3), c'est-à-dire la position adoptée par le dispositif d'accrochage 9 lorsqu'il est rangé et en contact ou quasi-contact du corps du capotage 1, et une position totalement dépliée dite « d'accrochage », c'est-à-dire la position adoptée par le dispositif d'accrochage 9 lorsqu'il est complètement sorti et peut être accroché à un support, tel un barreau de lit ou analogue. Le dispositif d'accrochage 9 pivote d'un angle donné autour de l'axe DD de pivotement montré en Fig. 3 In order to allow the attachment / securing of the bottle / valve block / cowling assembly to a support, such as a hospital bed or stretcher bar, the protective cowling 1 comprises, on the side of its rear face, a pivoting hooking device 9, between a fully folded position, called "rest" (shown schematically in Figure 3 ), that is to say the position adopted by the latching device 9 when it is stored and in contact or almost in contact with the casing body 1, and a fully unfolded position called “latching”, c 'is to say the position adopted by the hooking device 9 when it is completely extended and can be hung on a support, such as a bed bar or the like. The hooking device 9 pivots by a given angle around the pivot axis DD shown in Fig. 3

Une bouteille de gaz 2 équipée d'un capotage 1 avec dispositif indicateur de pression ou d'autonomie selon l'invention est particulièrement adaptée pour un usage en milieu médical, en particulier elle convient au stockage de tout gaz ou mélange gazeux médical, en particulier de type oxygène, air, N2O/O2, He/O2, NO/azote ou autre.A gas cylinder 2 equipped with a cover 1 with pressure or autonomy indicator device according to the invention is particularly suitable for use in a medical environment, in particular it is suitable for the storage of any medical gas or gas mixture, in particular of oxygen, air, N 2 O / O 2 , He / O 2 , NO / nitrogen or other type.
