Definitions

  • the invention relates to a pressurized gas container, in particular a pressurized gas bottle, equipped with a fluid dispensing valve comprising an electronic device with a digital display configured to start a time counter and automatically calculate an expiry date of the gas contained in the container and to display, if necessary, an expiry alert on the digital display, for example a dedicated alert icon.
  • Medical gases such as oxygen, NO/N 2 , N 2 O/O 2 , He/O 2 mixtures, medical air or other, are generally packaged in pressurized gas containers, in particular cylinders or gas canisters.
  • These gas containers are commonly equipped with a dispensing valve, with or without an integrated pressure relief system, used to supply the medical gas and with a needle or digital manometer used to display the residual gas pressure.
  • a dispensing valve with or without an integrated pressure relief system, used to supply the medical gas and with a needle or digital manometer used to display the residual gas pressure.
  • the valve and the manometer are protected by a protective cover, also called “cap”, used to protect them against shocks, falls, dirt...

Description

L'invention porte sur un récipient de gaz sous pression, en particulier une bouteille de gaz sous pression, équipé d'un robinet de distribution de fluide comprenant un dispositif électronique à afficheur numérique configuré pour démarrer un compteur temporal et calculer automatiquement une date de péremption du gaz contenu dans le récipient et pour afficher, le cas échéant, une alerte de péremption sur l'afficher numérique, par exemple une icône d'alerte dédiée.The invention relates to a pressurized gas container, in particular a pressurized gas bottle, equipped with a fluid dispensing valve comprising an electronic device with a digital display configured to start a time counter and automatically calculate an expiry date of the gas contained in the container and to display, if necessary, an expiry alert on the digital display, for example a dedicated alert icon.

Les gaz médicaux, tel l'oxygène, les mélanges NO/N2, N2O/O2, He/O2, l'air médical ou autre, sont généralement conditionnés dans des récipients de gaz sous pression, en particulier des bouteilles ou bonbonnes de gaz.Medical gases, such as oxygen, NO/N 2 , N 2 O/O 2 , He/O 2 mixtures, medical air or other, are generally packaged in pressurized gas containers, in particular cylinders or gas canisters.

Ces récipients de gaz sont couramment équipés d'un robinet de distribution, avec ou sans système de détente intégré, servant à fournir le gaz médical et d'un manomètre à aiguille ou digital servant à afficher la pression de gaz résiduelle. En général, le robinet et le manomètre sont protégés par un capotage de protection, aussi appelé « chapeau », servant à les prémunir contre les chocs, les chutes, les salissures...These gas containers are commonly equipped with a dispensing valve, with or without an integrated pressure relief system, used to supply the medical gas and with a needle or digital manometer used to display the residual gas pressure. In general, the valve and the manometer are protected by a protective cover, also called "cap", used to protect them against shocks, falls, dirt...

Ainsi, le document EP-A-2918893 propose une telle bouteille de gaz équipée d'un robinet à détendeur intégré ou RDI et d'un manomètre mécanique à aiguille, alors que le document EP-A-2918892 propose une bouteille de gaz équipée d'un dispositif électronique à écran d'affichage digital.Thus, the document EP-A-2918893 proposes such a gas cylinder equipped with a tap with integrated regulator or RDI and a mechanical needle pressure gauge, whereas the document EP-A-2918892 offers a gas cylinder fitted with an electronic device with a digital display screen.

Or, comme tous les médicaments, les gaz médicaux ont une date de péremption. L'utilisation d'un gaz au-delà de sa date de péremption doit être évitée car elle pourrait remettre en cause l'efficacité du traitement du patient avec ce gaz.However, like all medicines, medical gases have an expiry date. The use of a gas beyond its expiry date must be avoided because it could compromise the effectiveness of the treatment of the patient with this gas.

Equiper chaque bouteille de gaz d'une étiquette portant cette date de péremption est peu pratique et extrêmement fastidieux et ce, d'autant plus que l'étiquette de chaque bouteille doit être changée à chaque remplissage de la bouteille avec du gaz frais afin de réactualiser la date de péremption du gaz frais introduit dans la bouteille.Equipping each gas bottle with a label bearing this expiry date is impractical and extremely tedious, especially since the label of each bottle must be changed each time the bottle is filled with fresh gas in order to update the expiry date of the fresh gas introduced into the cylinder.

De plus, une telle étiquette peut se perdre, être arrachée ou détériorée et/ou conduire à des erreurs de lecture de la part de l'utilisateur.In addition, such a tag can get lost, be torn off or damaged and/or lead to reading errors by the user.

Enfin, l'utilisateur doit penser à vérifier que la date de péremption du gaz n'est pas passée avant chaque utilisation, ce qui est alors sujet à des oublis et engendre des risques d'utilisation de gaz périmé.Finally, the user must remember to check that the expiry date of the gas has not passed before each use, which is then subject to oversights and generates risks of using expired gas.

Le problème est dès lors de pouvoir calculer rapidement, facilement et automatiquement une date de péremption d'un gaz médical (i.e. médicament gazeux) contenu dans un récipient de gaz et par ailleurs d'alerter l'utilisateur lorsque la date de péremption est dépassée de manière à éviter que du gaz ne soit utilisé après sa date de péremption et donc à éviter par ailleurs les inconvénients susmentionnés.The problem is therefore to be able to quickly, easily and automatically calculate an expiry date for a medical gas (i.e. gaseous medicine) contained in a gas container and moreover to alert the user when the expiry date has passed by in such a way as to prevent gas from being used after its expiry date and therefore to avoid the aforementioned drawbacks.

Il comprend un raccord ou embout de distribution de gaz auquel peut être raccordé un appareil médical, un tuyau flexible ou un autre dispositif utilisant ou acheminant le gaz fourni par le robinet 3. Un organe de réglage du débit, à savoir ici un volant rotatif ou analogue, permet à un utilisateur de régler la valeur de débit de gaz souhaitée.The fluid dispensing valve 3 is mounted, typically screwed, at the level of the orifice in the neck of the gas bottle. It comprises a gas distribution connector or endpiece to which a medical device, a flexible pipe or another device can be connected using or conveying the gas supplied by the valve 3. A flow adjustment member, namely here a rotary wheel or analog, allows a user to set the desired gas flow rate value.

On peut prévoir une (ou des) poignée de portage raccordée au corps du capotage et dimensionnée pour pouvoir être saisie manuellement par un utilisateur afin de permettre une manipulation et/ou un transport aisé de l'ensemble récipient de gaz/robinet/capotage, et/ou un dispositif ou système d'accrochage mobile, de préférence pivotant, permettant d'accrocher l'ensemble bouteille de gaz/robinet/capotage à un support, tel un barreau de lit d'hôpital, à un brancard ou à une tringle ou analogue.It is possible to provide one (or more) carrying handles connected to the body of the cowling and sized to be able to be gripped manually by a user in order to allow easy handling and/or transport of the gas container/valve/hood assembly, and / or a mobile attachment device or system, preferably pivoting, allowing the bottle assembly to be attached gas/valve/covering to a support, such as a hospital bed bar, to a stretcher or to a rod or the like.

L'afficheur numérique 6 comprend un écran numérique, par exemple à cristaux liquides (LCD) ou autre, porté par le boitier rigide du dispositif électronique 7 et alimenté électriquement par une source d'énergie électrique (non visible) agencée dans le capotage, par exemple une ou des batteries ou piles disposées dans un logement à piles aménagé dans la paroi du corps de capotage et fermé par une trappe amovible ou analogue.The digital display 6 comprises a digital screen, for example liquid crystal (LCD) or other, carried by the rigid casing of the electronic device 7 and electrically powered by a source of electrical energy (not visible) arranged in the cowling, by example one or more batteries or cells arranged in a battery compartment arranged in the wall of the cowling body and closed by a removable hatch or the like.

Selon l'invention, les moyens de pilotage à microprocesseur 5 sont configurés pour traiter le ou les signaux de mesure fournis par le capteur de pression 4, lequel mesure la pression du gaz stocké dans le récipient 1, et pour déterminer une (ou des) valeur de pression mesurée à partir de ce ou des signaux de mesure.According to the invention, the microprocessor control means 5 are configured to process the measurement signal(s) provided by the pressure sensor 4, which measures the pressure of the gas stored in the container 1, and to determine one (or more) pressure value measured from this or measurement signals.

Ils permettent ensuite de détecter un remplissage (y compris un re-remplissage) du récipient de gaz 1 avec du gaz frais, par exemple lorsque la bouteille se trouve dans un centre de remplissage après avoir été utilisée et vidée du gaz qu'elle contenait, en comparant la (ou les) valeur de pression mesurée avec une valeur-seuil de pression de référence prédéfinie et mémorisée, typiquement une valeur-seuil de pression de référence d'au moins 130 bar abs, par exemple 137 bar abs ou 200 bar abs. Cette valeur-seuil de pression de référence prédéfinie peut être mémorisée au sein des moyens de mémorisation 9, telle une mémoire informatique de type EEPROM.They then make it possible to detect a filling (including a re-filling) of the gas container 1 with fresh gas, for example when the bottle is in a filling center after having been used and emptied of the gas it contained, by comparing the measured pressure value(s) with a predefined and stored reference pressure threshold value, typically a reference pressure threshold value of at least 130 bar abs, for example 137 bar abs or 200 bar abs . This predefined reference pressure threshold value can be stored in storage means 9, such as an EEPROM-type computer memory.

Lorsque les moyens de pilotage à microprocesseur 5 détectent une valeur de pression mesurée dans le récipient 1 supérieure à la valeur-seuil de pression de référence mémorisée, ils interprètent cette détection comme un remplissage du récipient de gaz 1 avec du gaz frais puisque tant que le récipient 1 était vide ou presque les valeurs de pression mesurées étaient toutes inférieures à cette valeur-seuil de pression de référence.When the microprocessor control means 5 detect a pressure value measured in the container 1 greater than the stored reference pressure threshold value, they interpret this detection as a filling of the gas container 1 with fresh gas since as long as the container 1 was or almost empty the pressure values measured were all below this reference pressure threshold value.

Les moyens de pilotage à microprocesseur 5 démarrent alors un compteur temporel 8 à partir de cette détection, en particulier ils le réinitialisent pour le mettre à zéro. De plus, les moyens de pilotage à microprocesseur 5 mémorisent (en 9) ce moment comme étant la « date de remplissage » du récipient 1, ce qui leur permet de calculer en outre une « date de péremption du gaz » à partir de la date de remplissage et commencent à comptabiliser le temps s'écoulant à partir de ladite date de remplissage.The microprocessor control means 5 then start a time counter 8 from this detection, in particular they reset it to set it to zero. In addition, the microprocessor control means 5 memorizes (at 9) this moment as being the "filling date" of the container 1, which allows them to additionally calculate a "gas expiry date" from the date filling and begin to count the time elapsing from the date of filling.

Lors de la réinitialisation du compteur temporel 8, les moyens de pilotage à microprocesseur 5 effacent, le cas échéant, toute autre date de remplissage et/ou de de péremption du gaz ayant été préalablement enregistrées, par exemple lors d'un remplissage précédent du récipient de gaz.When resetting the time counter 8, the microprocessor control means 5 erase, if necessary, any other date of filling and/or expiry of the gas having been previously recorded, for example during a previous filling of the container. gas.

La date de péremption du gaz est calculée par les moyens de pilotage à microprocesseur 5 en ajoutant une durée de péremption prédéfinie, typiquement de plusieurs années, par exemple de 5 années, à la date de remplissage. Cette date de péremption est enregistrée (en 9) par les moyens de pilotage à microprocesseur 5. Ceux-ci surveillent alors en permanence le récipient 1 pour détecter si le compteur temporel 8 dépasse la date de péremption qui reflète une péremption du gaz.The expiry date of the gas is calculated by the microprocessor control means 5 by adding a predefined expiry period, typically several years, for example 5 years, to the filling date. This expiry date is recorded (at 9) by the microprocessor control means 5. These then constantly monitor the container 1 to detect whether the time counter 8 exceeds the expiry date which reflects an expiry of the gas.

En cas de détection d'un tel dépassement de la durée donnée calculée à partir du démarrage du compteur temporel, c'est-à-dire de la date de péremption, les moyens de pilotage 5 sont configurés pour déclencher une alerte visuelle et/ou sonore afin d'avertir l'utilisateur de ce dépassement de date. Ainsi, le déclenchement d'une alerte visuelle peut se matérialiser par un affichage sur l'écran d'affichage d'une icône d'alerte 10 spécifique et s'accompagner de l'émission d'un signal sonore, voire d'un clignotement lumineux, par exemple de l'écran d'affichage 6 ou d'une (ou des) diode spécifique.In the event of detection of such an overrun of the given duration calculated from the start of the time counter, that is to say from the expiry date, the control means 5 are configured to trigger a visual alert and/or sound to warn the user of this date overrun. Thus, the triggering of a visual alert can take the form of a display on the display screen of a specific alert icon 10 and be accompanied by the emission of an audible signal, or even a flashing luminous, for example of the display screen 6 or of one (or more) specific diode.

En effet, comme tous les médicaments, les gaz médicaux ont une date de péremption. L'utilisation de ces gaz au-delà de la date prévue pourrait mettre à risque l'efficacité du traitement du patient.Indeed, like all medicines, medical gases have an expiry date. The use of these gases beyond the scheduled date could jeopardize the effectiveness of the patient's treatment.

Grâce à la présente invention, il est possible d'éviter qu'une bouteille de gaz médical ne soit utilisée après sa date de péremption.Thanks to the present invention, it is possible to prevent a medical gas cylinder from being used after its expiry date.

De plus, à chaque fois qu'un remplissage est détecté, la date de remplissage antérieure est écrasée, c'est-à-dire effacée comme susmentionné, et remplacée par la nouvelle date de remplissage. Il en va de même de la date de péremption calculée à partir de cette nouvelle date de remplissage. De cette façon, la date de péremption du gaz est actualisée à chaque passage du récipient en centre de remplissage, c'est-à-dire calculée à partir de chaque nouvelle date de remplissage.Moreover, each time a filling is detected, the previous filling date is overwritten, that is to say erased as mentioned above, and replaced by the new filling date. The same applies to the expiry date calculated from this new filling date. In this way, the expiry date of gas is updated each time the container passes through the filling centre, i.e. calculated from each new filling date.

Il est à noter que l'afficheur numérique 6 du dispositif 7 peut aussi afficher d'autres informations utiles, par exemple une valeur de débit de gaz (en L/min ou en une autre unité) ou encore une autonomie en gaz (en heures et minutes).It should be noted that the digital display 6 of the device 7 can also display other useful information, for example a gas flow rate value (in L/min or in another unit) or even a gas autonomy (in hours and minutes).

Plus généralement, l'afficheur numérique 6 comprend un écran de hauteur par exemple comprise entre 29 et 37 cm environ et de largeur par exemple comprise entre 39 et 43 cm environ.More generally, the digital display 6 comprises a screen of height for example comprised between 29 and 37 cm approximately and of width for example comprised between 39 and 43 cm approximately.

L'afficheur numérique 6 peut être agencé dans le panneau frontal, c'est-à-dire la façade avant, du boitier du dispositif électronique fixé sur le robinet de distribution de fluide 3 et logé dans une ouverture du corps du capotage de protection protégeant le robinet 3. Le panneau frontal peut comprendre en outre un bouton d'acquittement d'alarme.The digital display 6 can be arranged in the front panel, that is to say the front facade, of the case of the electronic device fixed to the fluid dispensing valve 3 and housed in an opening in the body of the protective cover protecting tap 3. The front panel may also include an alarm acknowledgment button.

Tous les composants nécessitant de l'énergie électrique pour fonctionner (i.e. microprocesseur, capteur, afficheur etc...) sont alimentés électriquement par une source d'énergie électrique agencée par exemple dans le capotage, par exemple une pile ou batterie électrique.All the components requiring electrical energy to operate (i.e. microprocessor, sensor, display, etc.) are electrically powered by an electrical energy source arranged for example in the cowling, for example an electric cell or battery.

D'une manière générale, un récipient de fluide 1, en particulier une bouteille de gaz, équipée d'un robinet, tel un RDI, protégé par un capotage selon l'invention est adaptée au stockage et à la fourniture de gaz sous pression, en particulier un gaz ou mélange gazeux médical, tel de l'oxygène, un mélange NO/N2, O2/N2O ou He/O2, de l'air ou autre.In general, a fluid container 1, in particular a gas cylinder, equipped with a tap, such as an RDI, protected by a cowling according to the invention is suitable for storing and supplying pressurized gas, in particular a medical gas or gaseous mixture, such as oxygen, an NO/N 2 , O 2 /N 2 O or He/O 2 mixture, air or other.
