- F17C2270/02—Applications for medical applications
Definitions
- the invention relates to a secure device for dispensing fluid to a user.
- the invention relates more particularly to the distribution of fluid contained in bottles intended for patients in a non-hospital environment, in the context of home care.
- fluid in the context of the present application means a gaseous, liquid or diphasic liquid-gas body.
- the opening of the fluid bottles is usually controlled by means of a plastic seal, a new plastic seal to be put back in place by the nursing staff after each use.
- the presence of a new seal ensures that the bottle is not used in the meantime by personnel who do not hold such plastic seals, ie unauthorized personnel of the patient type.
- the invention aims to remedy all or part of the disadvantages of the state of the art identified above, and in particular to provide means for securing access to containers adapted to contain the fluid, such as fluid bottles.
- the device conditions the unlocking of the valve of the container, the authentication of the user who presents his means of authentication.
- the use and administration of the fluid contained in the container is conditioned on the adequacy between the authentication information of the user and the predetermined value contained for example in a memory of the secure device.
- the nature of the authentication means and the communication channel depends on the type of interface installed on the secure device. Any communication technology of the type with or without contact is possible: RFID, NFC, WIFI, magnetic stripe card, smart card etc ...
- the use of a contactless communication improves the reliability of the system, because of the absence of contact zone, this type of zone being worn over time. This communication technology should preferably allow the establishment of a short-distance communication, low consumption and embedding security layers.
- the authentication information may be information about the medical personnel authorized to administer the treatment, or information about the patient to receive the treatment, or both information at a time.
- the type of authentication information expected depends on the setting of the device and the predefined authentication information which may be the sum of the authentication information of the medical staff and the patient.
- valve is not necessarily opened, i.e. passed to its second state, immediately.
- the medical staff user, may have to perform preliminary medical steps, such as preliminary care.
- the opening of the unlocked valve can be done manually by the medical staff.
- the second state of the valve corresponding to the opening of the valve may be a total opening of the valve or a partial opening, i.e. an intermediate opening determined by the dosage required by the patient.
- the detection means may be a housing adapted for insertion of the user authentication means, or may also be a push button that the user activates so as to wake the device and allow the establishment of the communication channel for its authentication.
- the authentication means used by the user and capable of communicating with the secure device for the exchange of authentication information may be of the type: card, keychain, mobile device (mobile phone, tablet, computer, etc.). It can be any type of means capable of establishing a communication link with the interface chosen for the device and capable of storing authentication information or retrieving it on a remote means.
- a remote server could manage the authorization of use of the bottles and a means of authentication of the mobile phone type retrieves this authorization on the remote server by means of a communication type 3G for example, then it establishes a connection of communication with the secure device whose type depends on the interface installed on the secure device.
- the secure device could include a plurality of interfaces, each interface can establish a different type of communication link depending on the nature of the authentication means available to users.
- the method may advantageously comprise a prior step of awakening the interface by the detection means.

Description
L'invention concerne un dispositif sécurisé de distribution de fluide à un utilisateur. L'invention concerne plus particulièrement la distribution de fluide contenu dans des bouteilles destinées à des patients en milieu non hospitalier, dans le cadre de soins à domicile.The invention relates to a secure device for dispensing fluid to a user. The invention relates more particularly to the distribution of fluid contained in bottles intended for patients in a non-hospital environment, in the context of home care.
On entend par fluide dans le cadre de la présente demande un corps gazeux, liquide ou diphasique liquide-gaz.The term "fluid" in the context of the present application means a gaseous, liquid or diphasic liquid-gas body.
Actuellement, certains fluides ne peuvent pas être administrés aux patients en dehors des hôpitaux du fait des risques inhérents à l'absence de contrôle suffisant de l'utilisation des bouteilles à domicile (ex : risque de surdosage). Parmi ces fluides, on peut notamment citer l'oxygène, ou un mélange de protoxyde d'azote et d'oxygène et en particulier un mélange équimolaire de protoxyde d'azote et d'oxygène.Currently, some fluids can not be administered to patients outside hospitals because of the risks inherent in the lack of sufficient control of the use of bottles at home (eg risk of overdose). Among these fluids, there may be mentioned oxygen, or a mixture of nitrous oxide and oxygen and in particular an equimolar mixture of nitrous oxide and oxygen.
L'ouverture des bouteilles de fluide est généralement contrôlée au moyen d'un scellé plastique, un nouveau scellé plastique devant être remis en place par le personnel soignant après chaque utilisation. La présence d'un nouveau scellé garantit la non-utilisation, entre temps, de la bouteille par un personnel non détenteur de tels scellés plastiques, i.e. un personnel non autorisé du type patient.The opening of the fluid bottles is usually controlled by means of a plastic seal, a new plastic seal to be put back in place by the nursing staff after each use. The presence of a new seal ensures that the bottle is not used in the meantime by personnel who do not hold such plastic seals, ie unauthorized personnel of the patient type.
Cependant, cette méthode n'est pas parfaitement fiable. Par exemple, dans le cadre des soins dispensés à domicile qui induisent un déplacement du personnel médical sur le lieu d'habitation du patient, l'oubli par le personnel médical du scellé plastique met en danger la fiabilité de cette méthode, la probabilité pour que la bouteille reste non scellée suite à son utilisation étant élevée.However, this method is not perfectly reliable. For example, in the context of home-based care that involves the displacement of medical personnel to the patient's place of residence, medical negligence of the plastic seal endangers the reliability of this method, the likelihood that the bottle remains unsealed due to its use being high.
La sécurisation de l'accès à l'utilisation de ces bouteilles est prépondérante en vue de pouvoir démocratiser l'utilisation de tels types de bouteilles à domicile.Securing access to the use of these bottles is preponderant in order to democratize the use of such types of bottles at home.
L'invention vise à remédier à tout ou partie des inconvénients de l'état de la technique identifiés ci-dessus, et notamment à proposer des moyens permettant de sécuriser l'accès aux récipients adaptés pour contenir le fluide, du type bouteilles de fluide.The invention aims to remedy all or part of the disadvantages of the state of the art identified above, and in particular to provide means for securing access to containers adapted to contain the fluid, such as fluid bottles.
Dans ce dessein, un aspect de l'invention se rapporte à un dispositif sécurisé de distribution de fluide à un utilisateur, ledit dispositif comportant :
- un récipient adapté pour contenir ledit fluide, ledit récipient comportant une vanne à travers laquelle le fluide peut être distribué à l'utilisateur, ladite vanne ayant un premier état dans lequel la vanne est fermée et un deuxième état dans lequel la vanne est ouverte ;
- un moyen de verrouillage de ladite vanne, ledit moyen de verrouillage étant mobile entre une première position dans laquelle il bloque la vanne dans le premier état et une deuxième position dans laquelle la vanne est librement mobile entre le premier état et le deuxième état ;
- un moyen de détection adapté pour détecter la présence d'un moyen d'authentification de l'utilisateur ;
- des moyens de commande activables par un signal de commande, lesdits moyens de commande étant adaptés pour faire passer le moyen de verrouillage de la première position à la deuxième position ;
- une interface adaptée pour l'établissement d'un canal de communication entre ledit moyen d'authentification de l'utilisateur et le dispositif sécurisé de distribution du fluide, ledit canal de communication étant adapté pour le transfert d'une information d'authentification, la réception de ladite information d'authentification par l'interface générant le signal de commande lorsque l'information d'authentification est égale à une valeur prédéterminée.
- a container adapted to contain said fluid, said container having a valve through which the fluid can be dispensed to the user, said valve having a first state in which the valve is closed and a second state in which the valve is open;
- a locking means of said valve, said locking means being movable between a first position in which it blocks the valve in the first state and a second position in which the valve is freely movable between the first state and the second state;
- detection means adapted to detect the presence of an authentication means of the user;
- control means operable by a control signal, said control means being adapted to move the locking means from the first position to the second position;
- an interface adapted for establishing a communication channel between said user authentication means and the secure fluid distribution device, said communication channel being adapted for the transfer of authentication information, the receiving said authentication information by the interface generating the control signal when the authentication information is equal to a predetermined value.
Le dispositif conditionne le déverrouillage de la vanne du récipient, à l'authentification de l'utilisateur qui présente son moyen d'authentification. L'utilisation et l'administration du fluide contenu dans le récipient est conditionné à l'adéquation entre l'information d'authentification de l'utilisateur et la valeur prédéterminée contenue par exemple dans une mémoire du dispositif sécurisé. La nature du moyen d'authentification et du canal de communication dépend du type d'interface installé sur le dispositif sécurisé. Toute technologie de communication du type avec ou sans contact est envisageable : RFID, NFC, WIFI, carte à bande magnétique, carte à puce etc... L'utilisation d'une communication sans contact améliore la fiabilité du système, du fait de l'absence de zone de contact, ce type de zone s'usant avec le temps. Cette technologie de communication doit, de préférence, permettre l'établissement d'une communication courte distance, basse consommation et embarquant des couches de sécurité.The device conditions the unlocking of the valve of the container, the authentication of the user who presents his means of authentication. The use and administration of the fluid contained in the container is conditioned on the adequacy between the authentication information of the user and the predetermined value contained for example in a memory of the secure device. The nature of the authentication means and the communication channel depends on the type of interface installed on the secure device. Any communication technology of the type with or without contact is possible: RFID, NFC, WIFI, magnetic stripe card, smart card etc ... The use of a contactless communication improves the reliability of the system, because of the absence of contact zone, this type of zone being worn over time. This communication technology should preferably allow the establishment of a short-distance communication, low consumption and embedding security layers.
L'information d'authentification peut être aussi bien une information concernant le personnel médical autorisé à administrer le traitement, ou bien une information concernant le patient devant recevoir le traitement, ou encore ces deux informations à la fois. Le type d'information d'authentification attendu dépend du paramétrage du dispositif et de l'information d'authentification prédéfinie qui peut être la somme des informations d'authentification du personnel médical et du patient.The authentication information may be information about the medical personnel authorized to administer the treatment, or information about the patient to receive the treatment, or both information at a time. The type of authentication information expected depends on the setting of the device and the predefined authentication information which may be the sum of the authentication information of the medical staff and the patient.
Une fois la vanne déverrouillée, la vanne n'est pas nécessairement ouverte, i.e. passée dans son deuxième état, immédiatement. Le personnel médical, utilisateur, peut avoir à effectuer des étapes préalables médicales, du type soins préliminaires. L'ouverture de la vanne déverrouillée peut se faire manuellement par le personnel médical. Le deuxième état de la vanne correspondant à l'ouverture de la vanne peut être une ouverture totale de la vanne ou bien une ouverture partielle, i.e. une ouverture intermédiaire déterminée par le dosage nécessaire au patient.Once the valve is unlocked, the valve is not necessarily opened, i.e. passed to its second state, immediately. The medical staff, user, may have to perform preliminary medical steps, such as preliminary care. The opening of the unlocked valve can be done manually by the medical staff. The second state of the valve corresponding to the opening of the valve may be a total opening of the valve or a partial opening, i.e. an intermediate opening determined by the dosage required by the patient.
Le moyen de détection peut être un logement adapté pour l'insertion du moyen d'authentification de l'utilisateur, ou bien également être un bouton poussoir que l'utilisateur enclenche de façon à réveiller le dispositif et permettre l'établissement du canal de communication pour son authentification.The detection means may be a housing adapted for insertion of the user authentication means, or may also be a push button that the user activates so as to wake the device and allow the establishment of the communication channel for its authentication.
Le moyen d'authentification utilisé par l'utilisateur et capable de communiquer avec le dispositif sécurisé pour l'échange de l'information d'authentification peut être du type: carte, porte-clefs, appareil mobile (téléphone mobile, tablette, ordinateur, etc.). Il peut s'agir de tout type de moyen capable d'établir une liaison de communication avec l'interface choisie pour le dispositif et capable de stocker une information d'authentification ou bien de la récupérer sur un moyen distant. Par exemple, un serveur distant pourrait gérer les autorisations d'utilisation des bouteilles et un moyen d'authentification du type téléphone mobile récupère cette autorisation sur le serveur distant au moyen d'une communication du type 3G par exemple, puis il établit une liaison de communication avec le dispositif sécurisé dont le type dépend de l'interface installée sur le dispositif sécurisé.The authentication means used by the user and capable of communicating with the secure device for the exchange of authentication information may be of the type: card, keychain, mobile device (mobile phone, tablet, computer, etc.). It can be any type of means capable of establishing a communication link with the interface chosen for the device and capable of storing authentication information or retrieving it on a remote means. For example, a remote server could manage the authorization of use of the bottles and a means of authentication of the mobile phone type retrieves this authorization on the remote server by means of a communication type 3G for example, then it establishes a connection of communication with the secure device whose type depends on the interface installed on the secure device.
Le dispositif sécurisé pourrait comporter une pluralité d'interfaces, chaque interface pouvant établir un type de liaison de communication différent suivant la nature des moyens d'authentification à disposition des utilisateurs.The secure device could include a plurality of interfaces, each interface can establish a different type of communication link depending on the nature of the authentication means available to users.
Outre les caractéristiques principales qui viennent d'être mentionnées dans le paragraphe précédent, le dispositif selon l'invention peut présenter une ou plusieurs caractéristiques complémentaires parmi les suivantes, considérées individuellement ou selon les combinaisons techniquement possibles :
- le canal de communication est établi lorsque la présence du moyen d'authentification de l'utilisateur est détectée par le moyen de détection. Ce dispositif permet ainsi avantageusement de conditionner le réveil de l'interface pour l'établissement du canal de communication à la détection de la présence du moyen d'authentification de l'utilisateur afin de limiter la consommation d'énergie du dispositif. Ainsi la partie électronique/électrique du dispositif, i.e. consommatrice d'énergie, permettant, entre autres, de déverrouiller la vanne de la bouteille en fonction de l'identité de l'utilisateur n'est réveillée que lorsque l'action d'identification de l'utilisateur doit être réalisée, c'est-à-dire lorsqu'un utilisateur met en contact, direct ou indirect, son moyen d'identification avec le dispositif sécurisé via le moyen de détection ;
- l'interface est un lecteur RFID. Le lecteur RFID (acronyme de radio frequency identification en anglais et radio-identification en français) du dispositif sécurisé, une fois activé par le moyen de détection active le marqueur, du type radio-étiquette du moyen d'authentification de l'utilisateur, afin de lire l'information d'authentification qui y est stocké. La technologie RFID présente une solution intéressante en matière de basse consommation, ce qui améliore l'autonomie du dispositif sécurisé, et de distance entre le dispositif sécurisé et le moyen d'authentification nécessaire à l'établissement du canal de communication. Cette distance est courte ce qui permet d'éviter les erreurs d'activation dues à des moyens d'authentification qui seraient à portée du dispositif sécurisé mais sans appartenir à l'utilisateur souhaitant s'authentifier auprès du dispositif ;
- le canal de communication est sécurisé et l'interface est un lecteur NFC. Le lecteur NFC (acronyme de Near Field Communication en anglais et communication en champ proche en français) du dispositif sécurisé peut établir un canal de communication avec tout dispositif d'authentification compatible avec la technologie NFC. L'utilisation du NFC a pour avantage de permettre l'établissement d'un canal de communication sécurisé et à courte distance (de l'ordre de la dizaine de centimètres) ce qui permet d'éviter les erreurs d'activation dues à des moyens d'authentification qui seraient à portée du dispositif sécurisé mais sans appartenir à l'utilisateur souhaitant s'authentifier auprès du dispositif ;
- les moyens de commande sont adaptés pour maintenir le moyen de verrouillage dans la première position lorsque l'information d'authentification n'est pas égale à une valeur prédéterminée. La vanne reste verrouillée en position de fermeture, i.e. dans le premier état, lorsque l'utilisateur qui tente d'utiliser le dispositif sécurisé n'y est pas autorisé ;
- le dispositif comporte des moyens adaptés pour faire évoluer la vanne vers un état intermédiaire prédéfini entre le premier état, dans lequel la vanne est fermée, et le deuxième état, dans lequel la vanne est totalement ouverte. Les moyens peuvent comporter une pluralité de clapets, ou orifices calibrés, disposés sur le trajet du fluide destiné à traverser la vanne, chacun des clapets étant orientable individuellement de façon à faire varier le débit du fluide traversant la vanne. Suivant les patients, l'administration du fluide peut avoir à se faire à des débits différents, on parle alors de posologie en débit. La vanne dans ce cas est partiellement ouverte. l'état intermédiaire prédéfini peut être transmis du moyen d'authentification de l'utilisateur au dispositif sécurisé au travers du canal de communication. Plus particulièrement, l'état intermédiaire prédéfini correspond à une valeur de débit choisie. Des moyens d'analyse et de calcul du dispositif peuvent effecteur la conversion entre débit voulu et état intermédiaire prédéfini. Dans ce cas, on parle de posologie en débit. Le traitement apporté au patient doit être fait pour une valeur précise de débit du fluide, cette valeur n'a pas à être réglée manuellement par l'utilisateur, elle peut être réglée automatiquement grâce à la valeur transmise par le moyen d'authentification de l'utilisateur au travers du canal de communication ;
- le dispositif comporte un moyen de rappel adapté pour faire passer le moyen de fermeture de la vanne du deuxième état au premier état après un laps de temps prédéterminé. Le laps de temps prédéterminé peut être transmis du moyen d'authentification de l'utilisateur au dispositif sécurisé au travers du canal de communication et être propre à chaque utilisateur/patient. Le moyen de rappel permet avantageusement d'automatiser la fermeture de la vanne une fois le traitement effectué. Il pourrait en outre être adapté pour faire passer le moyen de verrouillage de la vanne de la deuxième position à la première position après que le moyen de fermeture de la vanne soit revenu dans le premier état de façon à sécuriser automatiquement la fermeture du récipient contenant le fluide. Le moyen de rappel peut être un système à ressort, ledit ressort étant armé à l'ouverture de la vanne, par exemple manuellement par l'utilisateur, et désarmé au moyen d'un système électromécanique après le laps de temps prédéterminé. Dans ce cas, le système électromécanique est commandé par la valeur du laps de temps prédéterminé, on parle alors de posologie de durée ;
- le dispositif comporte un moyen de mesure de la pression du fluide contenu dans ledit récipient, ledit moyen de mesure étant relié à un moyen d'affichage, ledit moyen d'affichage étant activé lorsque la pression du fluide est inférieure à une valeur seuil. La mesure de pression permet de connaitre la capacité restante de la bouteille. La valeur seuil de la pression du fluide peut être transmise du moyen d'authentification de l'utilisateur au dispositif sécurisé au travers du canal de communication, il s'agit de la pression que devrait avoir le fluide contenu dans la bouteille pour la quantité de fluide demandée par l'utilisateur pour l'administration du fluide au patient. Lorsque cette valeur ne correspond pas à la pression de la bouteille correspondant à la capacité restante de la bouteille, cette information est transmise à des moyens d'activation du moyen d'affichage et le moyen d'affichage prévient l'utilisateur que la bouteille ne permettra pas de remplir les conditions de posologie demandées. Le moyen d'affichage peut alerter l'utilisateur de manière sonore ou visuelle ;
- le dispositif comporte un moyen de mesure du débit du fluide en sortie de la vanne. Le moyen de mesure du débit du fluide, du type débitmètre par exemple, permet de vérifier dans le cas d'une posologie en débit que cette dernière est respectée et de vérifier le bon fonctionnement de la vanne. Le moyen de mesure de débit du fluide peut également être relié au moyen d'affichage de façon à l'activer lorsque le débit mesuré n'est pas le même que le débit demandé par la valeur transmise par le moyen d'authentification par exemple afin d'alerter l'utilisateur. Le moyen de mesure de débit du fluide permet en outre, de travailler avec une posologie en quantité de fluide distribuée au patient, la quantité s'obtenant en effectuant l'intégrale du débit sur la durée. En outre, le moyen de mesure de débit du fluide peut être avantageusement relié à une mémoire optionnelle afin d'enregistrer les quantités de fluide administrées lors des différentes utilisations du dispositif. Ainsi, il est possible lorsque le récipient est vide, par exemple, de vérifier que le dispositif a été utilisé sans fraude en vérifiant que le contenu initial du récipient correspond aux quantités de fluide délivrées au cours des différentes administrations ;
- le moyen d'affichage relié aux moyens de mesure de débit et/ou de mesure de la pression du fluide peut permettre également à tout instant de donner un feedback à l'utilisateur de l'état d'avancement du traitement en cours d'administration ;
- le dispositif comporte un moyen de mesure de la température et des moyens pour corriger une mesure du débit obtenue par le moyen de mesure du débit du fluide en fonction de la température mesurée par le moyen de mesure de la température et/ou des moyens pour corriger une mesure de pression obtenue par le moyen de mesure de la pression du fluide en fonction de la température mesurée par le moyen de mesure de la température. Il s'agit plus particulièrement de la température ambiante. On entend par température ambiante, la température à l'extérieur du dispositif, et en particulier en dehors du récipient adapté pour contenir le fluide. Cette mesure de température ambiante permet de corriger les données de pression et de débit et ainsi d'obtenir les quantités de fluide et les débits corrigés en fonction des variations de température ;
- le dispositif comporte une mémoire pour l'enregistrement de données liées au fonctionnement du dispositif. Cette mémoire peut être reliée aux moyens de commande pour enregistrer leur activation, ce qui permet d'en déduire lorsque la vanne a été ouverte ou fermée. La mémoire peut également être reliée à l'interface afin d'enregistrer les tentatives d'authentification, et éventuellement leur réussite, mais aussi l'envoi d'informations par un utilisateur telles que ouverture intermédiaire prédéfinie, laps de temps prédéterminé pour la fermeture. La mémoire peut être reliée également au moyen d'affichage, au moyen de mesure de débit du gaz (mémoire optionnelle mentionnée dans le paragraphe en référence au moyen de mesure de débit du gaz), au moyen de mesure de la température. Toutes ces informations stockées dans la mémoire pourraient être récupérées par un utilisateur au moyen de l'interface du dispositif. L'utilisateur pourrait récupérer ces informations au moyen du moyen d'authentification de l'utilisateur qui peut dans certains cas être un terminal portable, ou bien au moyen d'un terminal portable habilité par le moyen d'authentification de l'utilisateur lorsque ce dernier est un simple badge par exemple.
- the communication channel is established when the presence of the authentication means of the user is detected by the detection means. This device thus advantageously makes it possible to condition the alarm clock of the interface for establishing the communication channel to detect the presence of the user's authentication means in order to limit the power consumption of the device. Thus, the electronic / electrical part of the device, ie the energy consumer, making it possible, among other things, to unlock the valve of the bottle according to the identity of the user, is only awakened when the identification action of the user the user must be realized, that is to say when a user contacts, directly or indirectly, his means of identification with the secure device via the detection means;
- the interface is an RFID reader. The RFID reader (acronym for radio frequency identification in English and radio-identification in French) of the secure device, once activated by the detection means activates the marker, of the radio-tag type of the user's authentication means, so that to read the authentication information stored there. RFID technology presents an interesting solution in terms of low consumption, which improves the autonomy of the secure device, and distance between the secure device and the authentication means necessary for the establishment of the communication channel. This distance is short which avoids activation errors due to authentication means that would be within range of the secure device but without belonging to the user wishing to authenticate with the device;
- the communication channel is secure and the interface is an NFC reader. The NFC (near field communication in English) of the secure device can establish a communication channel with any device authentication compatible with NFC technology. The advantage of using the NFC is that it enables the establishment of a secure and short-range communication channel (of the order of ten centimeters), which makes it possible to avoid activation errors due to means authentication that would be within range of the secure device but without belonging to the user wishing to authenticate with the device;
- the control means are adapted to maintain the locking means in the first position when the authentication information is not equal to a predetermined value. The valve remains locked in the closed position, ie in the first state, when the user who tries to use the secure device is not allowed to do so;
- the device comprises means adapted to evolve the valve to a predefined intermediate state between the first state, in which the valve is closed, and the second state, in which the valve is fully open. The means may comprise a plurality of valves, or calibrated orifices, arranged in the path of the fluid for passing through the valve, each of the valves being individually adjustable so as to vary the flow rate of the fluid passing through the valve. According to the patients, the administration of the fluid may have to be done at different flow rates, it is called dosage in flow. The valve in this case is partially open. the predefined intermediate state can be transmitted from the authentication means of the user to the secure device through the communication channel. More particularly, the predefined intermediate state corresponds to a chosen rate value. Means for analyzing and calculating the device can effect the conversion between the desired flow rate and the predefined intermediate state. In this case, we speak of dosage in flow. The treatment given to the patient must be done for a precise value of flow of the fluid, this value does not have to be set manually by the user, it can be adjusted automatically thanks to the value transmitted by the authentication means of the user. user through the communication channel;
- the device comprises a return means adapted to move the closing means of the valve of the second state to the first state after a predetermined period of time. The predetermined period of time can be transmitted from the user authentication means to the secure device through the communication channel and be specific to each user / patient. The return means advantageously makes it possible to automate the closure of the valve once the treatment has been performed. It could also be adapted to move the valve locking means from the second position to the first position after the closing means of the valve is returned to the first state so as to automatically secure the closure of the container containing the valve. fluid. The return means may be a spring system, said spring being armed at the opening of the valve, for example manually by the user, and disarmed by means of an electromechanical system after the predetermined period of time. In this case, the electromechanical system is controlled by the value of the predetermined period of time, it is referred to as duration dosage;
- the device comprises means for measuring the pressure of the fluid contained in said container, said measuring means being connected to a display means, said display means being activated when the pressure of the fluid is below a threshold value. The pressure measurement makes it possible to know the remaining capacity of the bottle. The threshold value of the fluid pressure can be transmitted from the user authentication means to the secure device through the communication channel, it is the pressure that should have the fluid contained in the bottle for the amount of fluid requested by the user for administering the fluid to the patient. When this value does not correspond to the pressure of the bottle corresponding to the remaining capacity of the bottle, this information is transmitted to means for activating the display means and the display means warns the user that the bottle will not fulfill the requested dosage requirements. The display means may alert the user in a sonic or visual manner;
- the device comprises means for measuring the flow of the fluid at the outlet of the valve. The means for measuring the flow rate of the fluid, of the flowmeter type, for example, makes it possible to verify, in the case of a dosage in flow rate, that the flow rate is respected and to verify the proper operation of the valve. The fluid flow measuring means may also be connected to the display means so as to activate it when the measured flow rate is not the same as the requested flow rate by the value transmitted by the authentication means, for example in order to to alert the user. The means for measuring the flow of the fluid also makes it possible to work with a posology in the amount of fluid dispensed to the patient, the quantity being obtained by performing the integral of the flow over the duration. In addition, the fluid flow measurement means may advantageously be connected to an optional memory in order to record the quantities of fluid administered during the various uses of the device. Thus, it is possible when the container is empty, for example, to verify that the device has been used without fraud by verifying that the initial content of the container corresponds to the quantities of fluid delivered during the different administrations;
- the display means connected to the flow measurement and / or fluid pressure measuring means may also make it possible at any moment to give the user a feedback on the progress of the treatment being administered. ;
- the device comprises means for measuring the temperature and means for correcting a measurement of the flow rate obtained by the fluid flow measurement means as a function of the temperature measured by the temperature measuring means and / or means for correcting a pressure measurement obtained by the means for measuring the pressure of the fluid as a function of the temperature measured by the means for measuring the temperature. It is more particularly the ambient temperature. By ambient temperature is meant the temperature outside the device, and in particular outside the container adapted to contain the fluid. This ambient temperature measurement corrects the pressure and flow data and thus obtaining fluid quantities and corrected flow rates as a function of temperature variations;
- the device comprises a memory for recording data related to the operation of the device. This memory can be connected to the control means to record their activation, which allows to deduce when the valve has been opened or closed. The memory can also be connected to the interface to record the authentication attempts, and possibly their success, but also the sending of information by a user such as predefined intermediate opening, predetermined time for closing. The memory can also be connected to the display means, by means of gas flow measurement (optional memory mentioned in the paragraph with reference to the gas flow measurement means), by means of temperature measurement. All this information stored in the memory could be retrieved by a user through the device interface. The user could retrieve this information by means of the user authentication means which may in some cases be a portable terminal, or by means of a portable terminal enabled by the user authentication means when last is a simple badge for example.

- a step of activating the control means when the control signal is generated, for the passage of the unlocking means from the first position to the second position;
- a step of passage of the valve from the first state to the second state for the distribution of fluid. The step of passing the valve from the first state to the second state, once the locking means has passed into the second position, can be done manually by an operator or automatically by an electromechanical system controlled by the control signal.
Le procédé peut avantageusement comporter une étape préalable de réveil de l'interface par le moyen de détection. Cette étape peut être réalisée par un opérateur appuyant sur un bouton poussoir par exemple ou bien par le moyen d'authentification qui envoie un signal de réveil au moyen de détection qui lui-même l'envoie à l'interface pour son activation une fois qu'il a été détecté.The method may advantageously comprise a prior step of awakening the interface by the detection means. This step may be carried out by an operator pressing a push button for example or by the authentication means which sends a wake-up signal to the detection means which itself sends it to the interface for activation once it has been activated. it has been detected.
Le procédé de distribution sécurisé d'un fluide à un utilisateur au moyen du dispositif sécurisé de distribution, ledit dispositif sécurisé de distribution comportant des moyens adaptés pour faire évoluer la vanne vers un état intermédiaire prédéfini entre le premier état dans lequel la vanne est fermée et le deuxième état dans lequel la vanne est totalement ouverte peut avantageusement comporter une étape de transmission de l'état intermédiaire prédéfini de la vanne du moyen d'authentification de l'utilisateur au dispositif sécuriséThe method for safely dispensing a fluid to a user by means of the secure dispensing device, said secure dispensing device comprising means adapted to make the valve evolve to a predefined intermediate state between the first state in which the valve is closed and the second state in which the valve is fully open may advantageously comprise a step of transmitting the predefined intermediate state of the valve of the user authentication means to the secure device
Cette transmission se fait via le canal de communication. L'état intermédiaire prédéfini de la vanne correspond à une posologie en débit, dans ce cas l'administration du fluide se fait à un débit précis, i.e. pour un état intermédiaire prédéfini de la vanne. Dans le cas où la valeur du débit prédéfinie serait transmise par le moyen d'authentification, le dispositif sécurisé pourrait comporter des moyens de calcul pour la conversion de cette valeur en débit en un état intermédiaire prédéfinie de la vanne, i.e. une position spécifique de clapets, ou orifices calibrés, sur le passage du fluide dans la vanne.This transmission is done via the communication channel. The predefined intermediate state of the valve corresponds to a dosage in flow, in this case the administration of the fluid is done at a precise flow rate, i.e. for a predefined intermediate state of the valve. In the case where the value of the predefined bit rate is transmitted by the authentication means, the secure device could comprise calculation means for converting this value into a flow rate in a predefined intermediate state of the valve, ie a specific valve position. , or calibrated orifices, on the passage of the fluid in the valve.
Le procédé de distribution sécurisé d'un fluide à un utilisateur peut également comporter :
- une étape d'envoi de l'information d'authentification du dispositif sécurisé à un serveur distant, ledit serveur distant comportant une mémoire dans laquelle est stockée la valeur prédéterminée ;
- une étape de comparaison de l'information d'authentification avec la valeur prédéterminée, ladite étape de comparaison étant réalisée par un moyen de calcul du serveur distant ;
- une étape de génération par le serveur distant d'un signal d'acquittement lorsque l'information d'authentification est égale à la valeur prédéterminée pour l'envoi du signal d'acquittement au dispositif sécurisé, la réception dudit signal d'acquittement par le dispositif sécurisé permettant la génération du signal de commande.
- a step of sending the authentication information of the secure device to a remote server, said remote server having a memory in which is stored the predetermined value;
- a step of comparing the authentication information with the predetermined value, said comparing step being performed by means of calculating the remote server;
- a step of generation by the remote server of an acknowledgment signal when the authentication information is equal to the predetermined value for sending the acknowledgment signal to the secure device, the reception of said acknowledgment signal by the secure device for generating the control signal.
Dans ce mode de réalisation, l'authentification d'un utilisateur pour le déblocage du dispositif est renforcée. En effet, la valeur prédéterminée n'est pas stockée sur le dispositif sécurisé mais sur un serveur distant auprès duquel le dispositif sécurisé demande la vérification de l'identité de l'utilisateur. Ce mode de réalisation permet la vérification en temps réel des droits du porteur du moyen d'authentification. En outre, le procédé peut comporter une étape de transmission des quantités de fluide/du débit de fluide à délivrer du serveur distant au dispositif sécurisé lorsque l'information d'authentification est égale à la valeur prédéterminée. Ces informations peuvent être intégrées au signal d'acquittement ou bien envoyée séparément.In this embodiment, the authentication of a user for unblocking the device is enhanced. Indeed, the predetermined value is not stored on the secure device but on a remote server with which the secure device requests verification of the identity of the user. This embodiment makes it possible to verify in real time the rights of the bearer of the authentication means. In addition, the method may include a step of transmitting fluid quantities / fluid flow to be delivered from the remote server to the secure device when the authentication information is equal to the predetermined value. This information can be integrated into the acknowledgment signal or sent separately.
D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui suit, en référence à la figure annexée :
- la
figure 1 , illustre schématiquement un dispositif sécurisé de distribution de fluide selon un mode de réalisation de l'invention.
- the
figure 1 , schematically illustrates a secure device for fluid distribution according to one embodiment of the invention.
A la
Le récipient 1 comporte une vanne 2. Le fluide contenu dans le récipient 1 est distribué vers l'extérieur du récipient 1 (selon le sens de la flèche représentée à la
Le dispositif comporte également un moyen de verrouillage 3 de la vanne 2. Ce moyen de verrouillage a le rôle d'un cadenas, il sécurise l'ouverture de la vanne et est mobile entre :
- une première position dans laquelle il bloque la vanne dans le premier état i.e. en position de fermeture de la vanne ; et
- une deuxième position dans laquelle la vanne est librement mobile entre le premier état et le deuxième état i.e. quand le moyen de verrouillage est dans la deuxième position, la vanne peut être librement ouverte ou fermée par un utilisateur ou de façon automatique.
- a first position in which it blocks the valve in the first state ie in the closed position of the valve; and
- a second position in which the valve is freely movable between the first state and the second state ie when the locking means is in the second position, the valve can be freely opened or closed by a user or automatically.
Le dispositif comporte en outre des moyens de commande 6 activables par un signal de commande. Les moyens de commande 6 sont reliés au moyen de verrouillage 3 de façon à pouvoir le faire passer de la première position, dans laquelle il bloque la vanne, à la deuxième position, dans laquelle il ne bloque plus la vanne.The device further comprises control means 6 activatable by a control signal. The control means 6 are connected to the locking means 3 so as to be able to move it from the first position, in which it blocks the valve, to the second position, in which it no longer blocks the valve.
Le dispositif comporte en outre un moyen de détection 4 pour la détection de la présence d'un moyen d'authentification 5 de l'utilisateur. Le moyen d'authentification 5, du type badge dans ce mode de réalisation, peut être inséré dans une fente/logement du moyen de détection 4 comportant par exemple un bouton poussoir. Lorsque le badge appuie sur le bouton poussoir lors de son insertion dans le logement du moyen de détection 4, le dispositif sécurisé est réveillé. En effet, le dispositif comporte une interface 7, qui est un lecteur RFID, dans ce mode de réalisation. L'interface 7 permet l'établissement d'un canal de communication entre le dispositif sécurisé, via l'interface 7, et le moyen d'authentification 5, qui est du type badge RFID dans ce mode de réalisation.The device further comprises a detection means 4 for detecting the presence of an authentication means 5 of the user. The authentication means 5, of the badge type in this embodiment, can be inserted into a slot / housing of the detection means 4 comprising for example a push button. When the badge presses the push button when inserted into the housing of the detection means 4, the secure device is awake. Indeed, the device comprises an
Lors de l'insertion par l'utilisateur du badge RFID dans le moyen de détection 4, le badge active l'établissement du canal de communication. Le canal de communication RFID est établi par le lecteur RFID 7 qui une fois réveillé active le marqueur RFID du badge RFID de l'utilisateur en lui fournissant l'énergie nécessaire. Le canal de communication n'est établi que si le moyen de détection 4 détecte la présence d'un moyen d'authentification 5, ce qui permet ainsi de limiter la consommation d'énergie du dispositif.When the user inserts the RFID badge in the detection means 4, the badge activates the establishment of the communication channel. The RFID communication channel is established by the
Le badge RFID 5 comporte une information d'authentification de l'utilisateur à qui il appartient et des informations sur la posologie en débit du fluide et en durée d'administration du fluide, dans ce mode de réalisation.The
L'information d'authentification est transmise au dispositif sécurisé par le canal de communication établi. Si cette information d'authentification correspond à une valeur prédéterminée que la bouteille reconnait, un signal de commande est généré, par exemple, par un calculateur C relié à l'interface 7. Le calculateur C est relié aux moyens de commande 6 et le signal de commande généré par le calculateur C les active de façon à ce qu'ils fassent passer le moyen de verrouillage 3 dans la deuxième position, dans laquelle la vanne n'est plus bloquée en position de fermeture. De la sorte, la vanne 2 est libre de mouvement et peut passer de la première position à la deuxième position et inversement.The authentication information is transmitted to the secure device over the established communication channel. If this authentication information corresponds to a predetermined value that the bottle recognizes, a control signal is generated, for example, by a computer C connected to the
Si l'information d'authentification transmise n'avait pas correspondu à la valeur contenue par exemple dans une mémoire du calculateur C permettant de déverrouiller le dispositif, le signal de commande n'aurait pas été généré et le moyen de verrouillage aurait été maintenu par les moyens de commande 6 dans la première position, i.e. la position dans laquelle il bloque la vanne. Ainsi, un utilisateur non autorisé ne peut pas déverrouiller le dispositif sécurisé de distribution du fluide.If the transmitted authentication information did not correspond to the value contained for example in a memory of the computer C enabling the device to be unlocked, the control signal would not have been generated and the locking means would have been maintained by the control means 6 in the first position, ie the position in which it blocks the valve. Thus, an unauthorized user can not unlock the secure fluid dispensing device.
Le badge RFID, dans ce mode de réalisation, comporte également des informations concernant la posologie en débit du fluide à administrer au patient par l'utilisateur. Dans ce cas, le dispositif comporte des moyens, du type clapets, ou orifices calibrés, adaptés pour faire évoluer la vanne entre le premier état, dans lequel elle est fermée et le deuxième état dans lequel elle est ouverte, la vanne adoptant une position intermédiaire prédéfinie entre le premier état et le deuxième état. La position intermédiaire prédéfinie correspond aux informations concernant la posologie en débit du fluide transmises par le badge RFID au moyen du canal de communication. Les clapets, ou orifices calibrés, permettent de faire varier la section d'ouverture de la vanne entre la position tout ouvert et tout fermé. Afin de vérifier si la posologie est bien respectée, un moyen de mesure de débit du fluide D est positionné en sortie de la vanne. Le moyen de mesure du débit D peut être relié à un calculateur d'un moyen d'affichage A afin d'activer le moyen d'affichage lorsque le débit effectif ne correspond pas au débit attendu. Lorsqu'il est activé, le moyen d'affichage peut afficher un message d'alerte à l'attention de l'utilisateur ou émettre un signal sonore.The RFID badge, in this embodiment, also includes information concerning the dose rate of the fluid to be administered to the patient by the user. In this case, the device comprises means, of the type valves, or calibrated orifices, adapted to evolve the valve between the first state, in which it is closed and the second state in which it is open, the valve adopting an intermediate position predefined between the first state and the second state. The predefined intermediate position corresponds to the flow rate information of the fluid transmitted by the RFID badge via the communication channel. Valves, or calibrated orifices, make it possible to vary the opening section of the valve between the fully open and fully closed position. In order to verify whether the dosage is well respected, a fluid flow measurement means D is positioned at the outlet of the valve. The flow measurement means D may be connected to a computer of a display means A in order to activate the display means when the actual flow rate does not correspond to the expected flow rate. When activated, the display means may display an alert message to the user or beep.
Le badge RFID, dans ce mode de réalisation, comporte également des informations concernant la posologie en durée d'administration du fluide au patient qui définissent un laps de temps prédéterminé au bout duquel la vanne doit repasser dans la première position, dans laquelle elle est fermée. A cet effet, lors de l'ouverture de la vanne par l'utilisateur, une fois qu'elle a été débloquée par le moyen de verrouillage, l'utilisateur arme un moyen de rappel (non visible sur la figure) du type ressort. Le ressort est relié à un dispositif électromécanique auquel le laps de temps prédéterminé est transmis par l'interface 7 de façon à enclencher un mouvement du dispositif électromécanique adapté pour provoquer le désarmement du ressort une fois le temps écoulé.The RFID badge, in this embodiment, also includes information regarding the dosage of fluid administration time to the patient that defines a predetermined period of time after which the valve must return to the first position, in which it is closed . For this purpose, when the user opens the valve, once it has been unlocked by the locking means, the user arms a return means (not visible in the figure) of the spring type. The spring is connected to an electromechanical device to which the predetermined period of time is transmitted by the
Le dispositif comporte également un moyen de mesure de la pression P du fluide contenu dans le récipient permettant de connaitre la contenance dudit récipient. Il est relié à un calculateur du moyen d'affichage A de façon à pouvoir prévenir afin d'activer le moyen d'affichage lorsque la pression du fluide contenu dans le récipient ne permettra pas de compléter le traitement déterminé par la posologie ou lorsque la bouteille est vide.The device also comprises a means for measuring the pressure P of the fluid contained in the container to know the capacity of said container. It is connected to a computer of the display means A so as to prevent in order to activate the display means when the pressure of the fluid contained in the container will not complete the treatment determined by the dosage or when the bottle is empty.
L'invention n'est pas limitée aux modes de réalisation précédemment décrits en référence aux figures et des variantes pourraient être envisagées sans sortir du cadre de l'invention.The invention is not limited to the embodiments previously described with reference to the figures and variants could be envisaged without departing from the scope of the invention.
