Definitions
- the invention relates to a small medical gas cylinder with tap or gas expansion valve, the whole being protected by a rigid protective shell, which can also be covered with a heat-shrinkable film ensuring hygiene compatible with the concept of medicine.
- pressurized gas cylinders are provided with or without an integrated system for operating the gas.
- the mechanical protection of the bottle and possibly of its integrated system of implementation of the gas can be provided by a cap or protective cover to protect the upper part of the bottle, that is to say the tap or tap-regulator for releasing the gas and the various elements associated therewith, such as one or more manometers or the like.
- thermoformed films improves the cleanliness and the hygiene of the bottle, it does not give a maximum guarantee because it never protects the entirety of the bottle and its system of implementation of the gas.
- some disposable devices are designed to fit the shape of the bottle and its gas implementation system. They are changed at each filling of the bottle but, in general, they imperfectly marry the complex contours of the bottle and its device for implementing the gas or these disposable devices are only suitable for large gas cylinders weighing several ten kilograms and having a size greater than 60 cm, therefore incompatible with use on small bottles, that is to say less than 50 cm in height.
- EP-A-903162 proposes to protect a reserve of breathing air with an outer cover formed of two sub-watertight parts with connecting pipe to the outside.
- EP-A-903162 proposes to protect a reserve of breathing air with an outer cover formed of two sub-watertight parts with connecting pipe to the outside.
- such equipment is not suitable for medical use, in particular for the reasons already mentioned above, since it simply constitutes a reserve of emergency air that can be used in an emergency, for example by the pilot of an aircraft in case crash at sea or similar.
- the present invention aims to solve these problems by improving existing equipment by providing equipment to effectively protect the medical gas cylinders and valves, pressure regulators, manometers and / or other elements equipping them against shocks and other damage, especially in the event of a fall on the floor, which also ensures better hygiene and more efficient cleaning of the gas cylinder, while offering better ergonomics, low weight and easier grip for the user. and making the product more aesthetic, therefore more compatible with a use of the treatment in public and / or ambulatory, that is to say outside hospital, since the equipment of the invention should be able to be used almost continued by the patients.
- the protective equipment of the bottle must be easily placed around the bottle to protect or, conversely, removed during maintenance operations, while allowing easy connection of the outlet of the tap or gas expansion valve equipping the medical gas cylinder to a gas distribution equipment, such as a valve on demand.
- the solution of the invention is then a portable gas distribution equipment comprising a gas cylinder having a height less than 50 cm, a valve or gas expansion valve mounted on the bottle, and mechanical protection means arranged around the bottle and said valve or gas expansion valve, said protection means comprising at least one outer rigid shell covering the entire body of the bottle and at least a portion of the tap or expansion valve, characterized in that the rigid shell external has an external profile having a constriction dimensioned so that it allows manual gripping of the equipment at the level of this restriction by a user.
- This throttling makes it possible to improve the ergonomics of the equipment of the invention but, above all, allows easy handling of the latter by the user since this constriction is dimensioned so that it allows manual gripping of the device. equipment at this constriction, that is to say that the constriction is sized to allow a grip of a hand of the equipment by a patient.
- the invention therefore proposes, as diagrammatically shown in the attached figures, to careen the assembly formed by the bottle 1 of gas under pressure, in particular a medical oxygen bottle or a mixture of oxygen and oxygen.
- helium and its system 2 of implementation of the gas, that is to say mainly the valve or valve-regulator mounted on this bottle, by a rigid shell 3, 3a, 3b protective plastic, which nevertheless allows to the user has easy access to the organs and elements of use, including one (or more) gas outlet connection carried by the tap or pressure reducer 2, and which also guarantees inviolability before its first implementation implemented by said user.
- One of the advantages of the whole of the invention is that the risk for the user is low because there is no direct contact between the user and the high pressure part since it is located under the protective shell, the only contact zone being the demand valve output 4 which is at low pressure.
- the protective shell 3, 3a, 3b of the invention covers the entire bottle 1, and its system 2 for operating the gas under pressure.
- this shell 3, 3a, 3b protector leads to enhanced ergonomics since it matches the contours of the body 1b and the bottom of the bottle 1, as well as those of the tap or the expansion valve 2 of gas arranged on the bottle 1.
- the present invention is particularly suitable for small gas cylinders for medical use, that is to say bottles having a height of between 20 and 40 cm, and a weight of 5 kg maximum, typically of the order of 1.5 at 2 kg.
- the gas cylinder may have a capacity (in water) of 0.47 liter and the maximum pressure of the gas therein is greater than or equal to 200 bar, preferably greater than or equal to 300 bar.
- a bottle made of a light material, in particular aluminum or a composite material is preferably chosen.
- the protection of the system 2 for operating the gas and the bottle 1 is provided by a shell 3, 3a, 3b protective formed of two half-shells 3a 3b surmounted by a cap-shutter 5.
- the half-shells 3a, 3b do not necessarily have identical structures, and the protective shell 3 may be formed of more than two sub -structures coming to associate with each other.
- one or more additional protective elements 14a, 14b are arranged between the half-shells 3a, 3b and the valve or pressure-reducing valve 2, preferably a pressure-reducing valve 2 optionally provided with pressure indicating means, such as a manometer or similar.
- the additional protective elements 14a, 14b are sandwiched between the inner wall of the half-shells 3a, 3b and the outer surface of the valve or pressure-reducing valve 2, as shown in FIG. Figure 1 .
- the additional protective elements 14a, 14b provide additional mechanical protection around the tap or expansion valve 2 so as to protect it against shocks and the like that could occur on the outer shell 3 and then affect the valve or valve-regulator 2, in the absence of such elements 14a, 14b.
- the additional protective elements 14a, 14b are fixed integrally to one another to form a kind of shield or internal protective screen of the tap or expansion valve 2.

Abstract
Description
L'invention porte sur une bouteille de gaz médical de petites dimensions avec robinet ou robinet-détendeur de distribution de gaz, l'ensemble étant protégé par une coque protectrice rigide, laquelle peut être également recouverte d'un film thermo-rétractable assurant une hygiène compatible avec la notion de médicament.The invention relates to a small medical gas cylinder with tap or gas expansion valve, the whole being protected by a rigid protective shell, which can also be covered with a heat-shrinkable film ensuring hygiene compatible with the concept of medicine.
Actuellement, les bouteilles de gaz sous pression sont pourvues ou non d'un système intégré de mise en oeuvre du gaz.Currently, pressurized gas cylinders are provided with or without an integrated system for operating the gas.
La protection mécanique de la bouteille et éventuellement de son système intégré de mise en oeuvre du gaz peut être assuré par un chapeau ou capotage de protection venant protéger la partie haute de la bouteille, c'est-à-dire le robinet ou robinet-détendeur de libération du gaz et les divers éléments qui y sont associés, le cas échéant, tels un ou des manomètres ou similaires.The mechanical protection of the bottle and possibly of its integrated system of implementation of the gas can be provided by a cap or protective cover to protect the upper part of the bottle, that is to say the tap or tap-regulator for releasing the gas and the various elements associated therewith, such as one or more manometers or the like.
Toutefois, l'utilisation d'un tel capotage de protection trouve rapidement ses limites puisqu'il ne protège pas l'ensemble du corps de la bouteille mais seulement sa partie haute.However, the use of such a protective cover quickly finds its limits since it does not protect the entire body of the bottle but only its upper part.
De plus, un tel dispositif de type chapeau n'est pas adapté pour garantir une propreté et une hygiène maximales de la bouteille.In addition, such a hat-type device is not suitable to ensure maximum cleanliness and hygiene of the bottle.
Afin d'améliorer ce point, il a été proposé d'appliquer un ou des films thermoformés sur le fût ou le chapeau de la bouteille. Bien que le film thermoformé améliore la propreté et l'hygiène de la bouteille, il ne donne pas une garantie maximale car il ne protège jamais l'intégralité de la bouteille et de son système de mise en oeuvre du gaz.In order to improve this point, it has been proposed to apply one or more thermoformed films to the barrel or the cap of the bottle. Although the thermoformed film improves the cleanliness and the hygiene of the bottle, it does not give a maximum guarantee because it never protects the entirety of the bottle and its system of implementation of the gas.
Par ailleurs, certains dispositifs jetables sont conçus pour épouser la forme de la bouteille et son système de mise en oeuvre du gaz. Ils sont changés à chaque remplissage de la bouteille mais, en général, ils épousent imparfaitement les contours complexes de la bouteille et de son dispositif de mise en oeuvre du gaz ou alors ces dispositifs jetables ne sont adaptés qu'aux grandes bouteilles de gaz pesant plusieurs dizaine de kilogrammes et ayant une taille supérieure à 60 cm, donc incompatibles avec une utilisation sur les bouteilles de petites tailles, c'est-à-dire de moins de 50 cm de hauteur.In addition, some disposable devices are designed to fit the shape of the bottle and its gas implementation system. They are changed at each filling of the bottle but, in general, they imperfectly marry the complex contours of the bottle and its device for implementing the gas or these disposable devices are only suitable for large gas cylinders weighing several ten kilograms and having a size greater than 60 cm, therefore incompatible with use on small bottles, that is to say less than 50 cm in height.
A ce titre, on peut citer les documents
En outre, l'ergonomie, l'esthétique, l'hygiène et surtout la facilité de préhension et de transport des bouteilles de gaz sous pression ne sont pas ou que très rarement prises en compte par les fabricants de bouteilles de gaz médical ou autre.In addition, ergonomics, aesthetics, hygiene and especially the ease of gripping and transport of pressurized gas cylinders are not or very rarely taken into account by manufacturers of medical or other gas cylinders.
A ce titre, on peut citer les documents
Or, il faut savoir que l'aspect esthétique et la facilité de préhension et de transport est très important, voire parfois prépondérant, pour l'utilisateur du produit, c'est-à-dire le patient, en particulier en milieu extra-hospitalier, c'est-à-dire lorsque le patient doit déambuler en étant en permanence alimenté en gaz respiratoire issu de la bouteille ainsi équipée.However, it should be known that the aesthetic appearance and ease of handling and transport is very important, and sometimes predominant, for the user of the product, that is to say the patient, especially in an out-of-hospital environment. , that is to say when the patient must walk while being continuously supplied with breathing gas from the bottle thus equipped.
Malgré cela, à ce jour, les seuls systèmes connus permettant d'améliorer un peu l'ergonomie de la bouteille de gaz sous pression sont des systèmes de préhension associés le plus souvent au chapeau ou au détendeur de protection porté par la bouteille de gaz, comme décrit notamment dans
Par ailleurs, on connaît aussi le document
En outre, certains des systèmes connus de l'art antérieur présentent une architecture complexe rendant le montage et le démontage de l'équipement complexe et fastidieux.In addition, some of the known systems of the prior art have a complex architecture making assembly and disassembly of equipment complex and tedious.
De là, on comprend que les systèmes et équipements existants actuellement sont très insuffisants et ne répondent pas aux attentes des utilisateurs.From this, it is understood that existing systems and equipment currently are very inadequate and do not meet the expectations of users.
La présente invention vise alors à résoudre ces problèmes en améliorant les équipements existants en proposant un équipement permettant de protéger efficacement les bouteilles de gaz médical et les robinets, robinets-détendeurs, manomètres et/ou autres éléments les équipant contre les chocs et détériorations diverses, notamment en cas de chute sur le sol, lequel garantisse, en outre, une meilleure hygiène et une propreté plus efficace de la bouteille de gaz, tout en offrant une meilleure ergonomie, un faible poids et une prise en main plus aisée pour l'utilisateur et en rendant le produit plus esthétique, donc plus compatible avec un usage du traitement en public et/ou en déambulatoire, c'est-à-dire hors milieu hospitalier, puisque l'équipement de l'invention devra pouvoir être utilisé de manière quasiment continue par les patients.The present invention aims to solve these problems by improving existing equipment by providing equipment to effectively protect the medical gas cylinders and valves, pressure regulators, manometers and / or other elements equipping them against shocks and other damage, especially in the event of a fall on the floor, which also ensures better hygiene and more efficient cleaning of the gas cylinder, while offering better ergonomics, low weight and easier grip for the user. and making the product more aesthetic, therefore more compatible with a use of the treatment in public and / or ambulatory, that is to say outside hospital, since the equipment of the invention should be able to be used almost continued by the patients.
De plus, l'équipement de protection de la bouteille doit pouvoir être facilement mis en place autour de la bouteille à protéger ou, à l'inverse, démonté lors des opérations de maintenance, tout en permettant un raccordement aisé du raccord de sortie du robinet ou robinet-détendeur de gaz équipant la bouteille de gaz médical à un matériel de distribution de gaz, telle une valve à la demande.In addition, the protective equipment of the bottle must be easily placed around the bottle to protect or, conversely, removed during maintenance operations, while allowing easy connection of the outlet of the tap or gas expansion valve equipping the medical gas cylinder to a gas distribution equipment, such as a valve on demand.
La solution de l'invention est alors un équipement portatif de distribution de gaz comprenant une bouteille de gaz ayant une hauteur inférieure à 50 cm, un robinet ou robinet-détendeur de gaz monté sur la bouteille, et des moyens de protection mécanique agencées autour de la bouteille et dudit robinet ou robinet-détendeur de gaz, lesdits moyens de protection comprenant au moins une coque rigide externe recouvrant la totalité du corps de la bouteille et au moins une partie du robinet ou robinet-détendeur, caractérisé en ce que la coque rigide externe a un profil externe présentant un étranglement dimensionné de telle sorte qu'il permet une préhension manuelle de l'équipement au niveau de cet étranglement par un utilisateur.The solution of the invention is then a portable gas distribution equipment comprising a gas cylinder having a height less than 50 cm, a valve or gas expansion valve mounted on the bottle, and mechanical protection means arranged around the bottle and said valve or gas expansion valve, said protection means comprising at least one outer rigid shell covering the entire body of the bottle and at least a portion of the tap or expansion valve, characterized in that the rigid shell external has an external profile having a constriction dimensioned so that it allows manual gripping of the equipment at the level of this restriction by a user.
Cet étranglement permet d'améliorer l'ergonomie de l'équipement de l'invention mais surtout autorise une prise en main aisée de celui-ci par l'utilisateur puisque cet étranglement est dimensionné de telle sorte qu'il autorise une préhension manuelle de l'équipement au niveau de cet étranglement, c'est-à-dire que l'étranglement est dimensionné pour permettre une prise d'une main de l'équipement par un patient.This throttling makes it possible to improve the ergonomics of the equipment of the invention but, above all, allows easy handling of the latter by the user since this constriction is dimensioned so that it allows manual gripping of the device. equipment at this constriction, that is to say that the constriction is sized to allow a grip of a hand of the equipment by a patient.

L'invention va être mieux comprise grâce à la description suivante faite en références aux Figures annexées.The invention will be better understood from the following description given with reference to the appended figures.
L'invention se propose donc, comme schématisé sur les Figures ci-annexées, de caréner l'ensemble formé par la bouteille 1 de gaz sous pression, en particulier une bouteille d'oxygène médical ou d'un mélange d'oxygène et d'hélium, et son système 2 de mise en oeuvre du gaz, c'est-à-dire principalement le robinet ou robinet-détendeur monté sur cette bouteille, par une coque rigide 3, 3a, 3b protectrice en matière plastique, laquelle permette néanmoins à l'utilisateur d'avoir un accès aisé aux organes et éléments d'utilisation, notamment à un (ou plusieurs) raccord de sortie de gaz porté par le robinet ou robinet-détendeur 2, et qui garantisse par ailleurs une inviolabilité avant sa première mise en oeuvre par ledit utilisateur.The invention therefore proposes, as diagrammatically shown in the attached figures, to careen the assembly formed by the
En effet, l'accès au raccord de sortie du gaz équipant le robinet ou le robinet-détendeur 2 monté sur le col de la bouteille doit être possible et aisé pour l'utilisateur, notamment lorsqu'il souhaite y fixer une valve 4 à la demande ou tout autre dispositif analogue de distribution de gaz, tel un dispositif de nébulisation.Indeed, access to the gas outlet fitting equipping the valve or the expansion valve 2 mounted on the neck of the bottle must be possible and easy for the user, especially when he wishes to attach a valve 4 to the application or any other similar gas distribution device, such as a nebulizer device.
Un des avantages de l'ensemble de l'invention est que le risque pour l'utilisateur est faible car il n'y pas de contact direct entre l'utilisateur et la partie haute pression puisqu'elle est située sous la coque de protection, la seule zone de contact étant la sortie de valve à la demande 4 qui est à basse pression.One of the advantages of the whole of the invention is that the risk for the user is low because there is no direct contact between the user and the high pressure part since it is located under the protective shell, the only contact zone being the demand valve output 4 which is at low pressure.
La coque protectrice 3, 3a, 3b de l'invention recouvre toute la bouteille 1, ainsi que son système 2 de mise en oeuvre du gaz sous pression.The
De plus, la forme particulière de cette coque 3, 3a, 3b protectrice conduit à une ergonomie renforcée puisqu'elle épouse les contours du corps 1b et du fond la de la bouteille 1, ainsi que ceux du robinet ou du robinet-détendeur 2 de gaz agencé sur la bouteille 1.In addition, the particular shape of this
La présente invention est particulièrement adaptée aux petites bouteilles de gaz à usage médical, c'est-à-dire des bouteilles ayant une hauteur comprise entre 20 et 40 cm, et un poids de 5 kg au maximum, typiquement de l'ordre de 1.5 à 2 kg. A titre d'exemple, la bouteille de gaz peut avoir une contenance (en eau) de 0,47 litre et la pression maximale du gaz dans celle-ci est supérieure ou égale à 200 bar, de préférence supérieure ou égale à 300 bars.The present invention is particularly suitable for small gas cylinders for medical use, that is to say bottles having a height of between 20 and 40 cm, and a weight of 5 kg maximum, typically of the order of 1.5 at 2 kg. For example, the gas cylinder may have a capacity (in water) of 0.47 liter and the maximum pressure of the gas therein is greater than or equal to 200 bar, preferably greater than or equal to 300 bar.
En outre, pour diminuer au maximum le poids de l'équipement, on choisit de préférence une bouteille en un matériau léger, en particulier en aluminium ou en matériau composite.In addition, to minimize the weight of the equipment, a bottle made of a light material, in particular aluminum or a composite material, is preferably chosen.
De façon plus détaillée, comme visible sur la
Afin d'améliorer encore la protection du robinet ou robinet-détendeur 2 monté sur la bouteille 1, comme montré en
Autrement dit, les éléments protecteurs 14a, 14b supplémentaires sont pris en 'sandwich' entre la paroi interne des demi-coques 3a, 3b et la surface externe du robinet ou robinet-détendeur 2, comme montré en
Plus précisément, les éléments protecteurs 14a, 14b supplémentaires viennent constituer une protection mécanique supplémentaire autour du robinet ou robinet-détendeur 2 de manière à le protéger contre les chocs et analogues qui pourraient survenir sur la coque 3 externe et se répercuter ensuite sur le robinet ou robinet-détendeur 2, en l'absence de tels éléments 14a, 14b. De préférence, les éléments protecteurs 14a, 14b supplémentaires se fixent solidairement l'un à l'autre pour former une sorte de bouclier ou écran protecteur interne du robinet ou robinet-détendeur 2. Pour une plus grande efficacité de protection, les éléments protecteurs 14a, 14b sont préférentiellement conformés pour épouser les contours de tout ou partie de la surface externe dudit robinet ou robinet-détendeur 2.More specifically, the additional
Les éléments protecteurs 14a, 14b sont avantageusement formés en un matériau de type plastique, tel un polymère ou analogue.The
Les deux demi-coques 3a, 3b, viennent se fixer l'une à l'autre, via des moyens d'accrochage 10, 11, 100, 111 portés par ou agencés sur la paroi interne et/ou le fond 3c desdites demi-coques 3a, 3b et/ou par les éléments protecteur 14a, 14b, protégeant le système 2 de mise en oeuvre du gaz.The two half-
Les moyens d'accrochage peuvent comprendre des griffes 10 d'accrochage portées par l'une des demi-coques 3a, 3b coopérant avec des moyens complémentaires agencés sur l'autre demi-coque. En outre, de manière à faciliter le positionnement et l'emboîtement des demi-coques 3a, 3b l'une avec l'autre, des renforts internes 11 sont prévus sur la paroi périphérique interne et/ou sur le fond 3c des demi-coques 3a, 3b, lesquels renforts 11 permettent aussi d'améliorer le maintien de la bouteille 1 à l'intérieur des coques 3a, 3b en formant des butées s'opposant à d'éventuels déplacements latéraux intempestifs de la bouteille 1, lors du transport de l'équipement par l'utilisateur par exemple. De préférence, les renforts 11 et/ou les griffes 10 d'accrochage et les demi-coques 3a, 3b sont moulés d'une seule pièce.The attachment means may comprise hooking claws carried by one of the half-
La fixation des demi-coques 3a, 3b aux éléments protecteurs 14a, 14b internes se fait grâce à des moyens de fixation 100, 111 portés par les demi-coques 3a, 3b et les éléments protecteurs 14a, 14b, et coopérant les uns avec les autres en vue de permettre leur fixation solidaire, en particulier des éléments de fixation 100, 111 par emboîtement ou similaire. Préférentiellement, ces éléments de fixation 100, 111 et les demi-coques 3a, 3b et, par ailleurs, les éléments protecteurs 14a, 14b sont moulés d'une seule pièce. De préférence, les éléments de fixation 100, 111 sont portés par et/ou aménagés dans la paroi interne des demi-coques 3a, 3b et la paroi externe des éléments protecteurs 14a, 14b.The fixing of the half-
Grâce au capuchon-obturateur 5 recouvrant la partie supérieure de la bouteille 1 et venant se fixer également aux demi-coques 3a, 3b, on assure un carénage complet de la bouteille 1 et de son système 2 de mise en oeuvre du gaz, et par ailleurs une inviolabilité de l'ensemble et une continuité de l'hygiène puisque ce capuchon-obturateur 5 empêche notamment les entrées de poussières ou analogue au niveau de la partie supérieure de la bouteille 1. Plus précisément, la garantie d'inviolabilité est obtenue grâce à un opercule 13 d'inviolabilité monté sur le capuchon 5 et qui doit être retiré par l'utilisateur avant la première utilisation du gaz. Ceci permet donc aussi de distinguer une bouteille pleine non utilisée, donc avec opercule 13, d'une bouteille déjà utilisée, c'est-à-dire sans opercule.Thanks to the cap-
En outre, le profil externe obtenu après fixation des deux demi-coques 3a, 3b, l'une avec l'autre, permet une préhension optimisée manuelle de l'équipement au niveau d'un étranglement 12 formé dans les demi-coques 3a, 3b aux environs du tiers supérieur desdits demi-coques. Préférentiellement, cet étranglement 12 est dimensionné de telle sorte qu'il autorise une préhension manuelle de l'équipement au niveau de cet étranglement 12, c'est-à-dire qu'il est dimensionné pour permettre une prise d'une main de l'équipement par un patient.In addition, the external profile obtained after fixing the two half-
De plus, cet étranglement 12 confère une esthétique nouvelle à l'équipement de l'invention particulièrement adapté à un usage dans le domaine de la santé et plus particulièrement à un usage par des patients traités à domicile.In addition, this
Avantageusement, un film thermoformé jetable est disposé sur la périphérie des demi-coques externes, lequel contribue à garantir une propreté et une hygiène maximales de l'équipement et permet de véhiculer différents graphismes, étiquetages, mentions légales, consignes d'utilisation.Advantageously, a disposable thermoformed film is disposed on the periphery of the outer half-shells, which contributes to ensuring maximum cleanliness and hygiene of the equipment and allows to convey different graphics, labeling, legal notices, instructions for use.
En outre, un bouton-poussoir 8 coopérant avec la vanne 4 donne au patient la possibilité d'augmenter s'il en ressent le besoin, le débit du gaz reçu, par exemple en activant ce bouton 8, le patient recevra 1,5 fois plus d'oxygène que le réglage fixe donnée par la valve 4.
