masquemask
respiratoire nasal incorporant une turbine délivrant du gaz sous pression audit masque, et un 5 dispositif de traitement des troubles respiratoires, notamment de traitement de l'apnée du sommeil, comprenant un tel ensemble. nasal respiratory system incorporating a turbine delivering gas under pressure to said mask, and a device for treating respiratory disorders, in particular for treating sleep apnea, comprising such an assembly.
Les dispositifs utilisés pour le traitement de l'apnée du sommeil du type CPAP (Continuous Positive Airway Pressure pour Pression Positive Continue) et ceux utilisés pour l'assistance ventilatoire à deux niveaux de pression du type VNDP (Ventilation nasale à deux 10 niveaux de pression ou en anglais Bi-Level Positive Airway Pressure) comprennent classiquement un générateur 2 de pression, un masque nasal 8 et un tuyau 7 ou conduit inspiratoire raccordant le masque 8 au générateur 2 de pression. Un tel appareil est schématisé sur la figure 1. The devices used for the treatment of sleep apnea of the CPAP type (Continuous Positive Airway Pressure for Continuous Positive Pressure) and those used for ventilatory assistance at two pressure levels of the VNDP type (Nasal ventilation at two pressure levels or in English Bi-Level Positive Airway Pressure) conventionally comprise a pressure generator 2, a nasal mask 8 and a pipe 7 or inspiratory conduit connecting the mask 8 to the pressure generator 2. Such an apparatus is shown diagrammatically in FIG. 1.
Plus précisément, comme montré sur la figure 1, le générateur 2 de pression 1 5 comprend essentiellement un groupe moto-turbine 1, 3 alimenté par des moyens d'alimentation électrique 4 et commandé par des moyens électroniques 5 de commande. More specifically, as shown in FIG. 1, the pressure generator 2 5 essentially comprises a motor-turbine group 1, 3 supplied by electrical supply means 4 and controlled by electronic control means 5.
Le masque 8 est habituellement pourvu d'un orifice 6 de fuite calibré permettant l'évacuation vers l'atmosphère des gaz expirés par le patient, lesquels sont chargés de C02. The mask 8 is usually provided with a calibrated leak orifice 6 allowing the evacuation to the atmosphere of the gases exhaled by the patient, which are loaded with CO2.
Le masque nasal 8 est appliqué et maintenu sur le nez du patient, durant son 2 0 sommeil, au moyen de sangles de maintien ou analogues. The nasal mask 8 is applied and held on the patient's nose during sleep by means of holding straps or the like.
Des dispositifs de traitement équipés de telles moto-turbines ont notamment été décrits par les documents FR-A-2806759, WO-A-99/22794, DE-A4438750, DE-A-19714644, DE-A-4405577 et DE-A-4233941. Treatment devices equipped with such motor-turbines have in particular been described by documents FR-A-2806759, WO-A-99/22794, DE-A4438750, DE-A-19714644, DE-A-4405577 and DE-A -4233941.
Ces dispositifs ont fait la preuve de leur efficacité dans le traitement de l'apnée du 25 sommeil et leur usage est, à ce titre, de plus en plus prescrit ou recommandé par les médecins aux personnes souffrant de troubles respiratoires du sommeil, en particulier d'apnées du sommeil. These devices have proven their effectiveness in the treatment of sleep apnea and their use is, as such, increasingly prescribed or recommended by doctors for people suffering from respiratory sleep disorders, in particular of sleep apnea.
Cependant, il subsiste encore des problèmes non ou incomplètement résolus se posant lors de l'utilisation de ces appareils, en particulier des problèmes liés à l'inconfort pour le patient et au coût de ces dispositifs. However, there are still unsolved or incomplete problems arising when using these devices, in particular problems related to discomfort for the patient and the cost of these devices.
Ainsi, le tuyau reliant le masque au générateur de pression engendre un inconfort 5 important pour le patient car, du fait de sa relative rigidité, ce tuyau exerce une contrainte permanente sur le masque, ce qui oblige à opérer un serrage assez fort du masque contre le visage du patient pour éviter des fuites de gaz trop importantes autour du masque. Thus, the pipe connecting the mask to the pressure generator generates significant discomfort for the patient because, due to its relative rigidity, this pipe exerts a permanent stress on the mask, which means that the mask has to be tightened fairly tightly. the patient's face to avoid excessive gas leaks around the mask.
Le tuyau représente également un volume tampon important entre le patient et le générateur de pression qui nécessite, pour évacuer le C02 expiré à l'atmosphère, d'avoir un 10 débit de rinçage délivré par le générateur de pression et un orifice de fuite à proximité du patient. Cette fuite permanente représente une nuisance sonore forte pour le patient. The pipe also represents a large buffer volume between the patient and the pressure generator which requires, in order to evacuate the expired CO 2 to the atmosphere, to have a flushing flow delivered by the pressure generator and a leak orifice nearby. of the patient. This permanent leak represents a strong noise nuisance for the patient.
En outre, le tuyau a un impact non négligeable sur le coût global du dispositif car il doit répondre à des exigences strictes, en termes de souplesse et résistance à l'écrasement. In addition, the pipe has a significant impact on the overall cost of the device because it must meet strict requirements, in terms of flexibility and resistance to crushing.
Le problème qui se pose alors est de pouvoir améliorer les masques et appareils 15 existants, de manière à pallier les inconvénients susmentionnés, tout en conservant les performances nécessaires à l'efficacité du traitement. The problem which then arises is to be able to improve existing masks and apparatuses, so as to overcome the aforementioned drawbacks, while retaining the performance necessary for the effectiveness of the treatment.
La solution de l'invention est alors un ensemble respiratoire formé d'un masque respiratoire nasal incorporant une turbine. The solution of the invention is then a respiratory assembly formed by a nasal respiratory mask incorporating a turbine.
Selon le cas, l'ensemble de l'invention peut comprendre l'une ou plusieurs des 2 0 caractéristiques techniques suivantes: - il incorpore, en outre, un moteur électrique couplé directement ou indirectement à la turbine. Depending on the case, the assembly of the invention may include one or more of the following technical characteristics: - it also incorporates an electric motor directly or indirectly coupled to the turbine.
- le masque comprend une coque formant volume interne et dimensionnée de manière à pouvoir recevoir tout ou partie de la région nasale d'un utilisateur. - The mask comprises a shell forming an internal volume and dimensioned so as to be able to receive all or part of the nasal region of a user.
- la turbine comprend un capotage stationnaire dans lequel est agencée au moins une roue à aubes mobile en rotation autour d'un axe de rotation, ledit capotage comportant une bouche d'aspiration permettant l'entrée de gaz dans ledit capotage et une bouche d'expulsion de gaz communiquant fluidiquement avec l'intérieur de la coque du masque. - The turbine comprises a stationary cowling in which is arranged at least one paddle wheel movable in rotation about an axis of rotation, said cowling comprising a suction mouth allowing the entry of gas in said cowling and a mouth of gas expulsion communicating fluidically with the interior of the mask shell.
- la coque du masque est dépourvue d'orifice de fuite. - the mask shell has no leakage orifice.
- le masque comporte un capteur de pression agencé de manière à pouvoir mesurer la pression à l'intérieur de la coque dudit masque. - The mask comprises a pressure sensor arranged so as to be able to measure the pressure inside the shell of said mask.
- la turbine a une vitesse de rotation maximum comprise entre 10000 et 60000 tours/minute, et/ou un diamètre interne compris entre 30 et 90 mm. - The turbine has a maximum rotation speed of between 10,000 and 60,000 rpm, and / or an internal diameter between 30 and 90 mm.
- un moyen d'humidification est agencé sur le trajet du gaz, de préférence entre la bouche d'aspiration permettant l'entrée de gaz dans ledit capotage et la roue à aubes. - A humidification means is arranged on the gas path, preferably between the suction mouth allowing the entry of gas into said cowling and the impeller.
- il a un poids compris entre 200 g et l kg. - it has a weight between 200 g and l kg.
Selon un autre aspect, l'invention porte aussi sur un dispositif de traitement des troubles respiratoires, en particulier de l'apnée du sommeil, comprenant: - un ensemble selon l'invention comportant un masque, une turbine et un moteur électrique, - des moyens de commande permettant de commander le fonctionnement de la turbine et - des moyens d'alimentation électrique pour alimenter en courant électrique le moteur 15 et/ou les moyens de commande. According to another aspect, the invention also relates to a device for treating respiratory disorders, in particular sleep apnea, comprising: - an assembly according to the invention comprising a mask, a turbine and an electric motor, - control means for controlling the operation of the turbine and - electrical supply means for supplying electric current to the motor 15 and / or the control means.
Selon le cas, le dispositif de l'invention peut comprendre l'une ou plusieurs des caractéristiques techniques suivantes: - le moteur électrique est porté par l'ensemble masque/turbine et est connecté aux moyens de commande et aux moyens d'alimentation électrique par l'intermédiaire d'au moins 2 0 un moyen de connexion, de préférence un ou plusieurs câbles électriques. Depending on the case, the device of the invention may include one or more of the following technical characteristics: - the electric motor is carried by the mask / turbine assembly and is connected to the control means and to the electric supply means by through at least one connection means, preferably one or more electrical cables.
- le moteur électrique, les moyens de commande et les moyens d'alimentation électrique sont agencés dans un boîtier, le moteur électrique étant couplé à l'axe de rotation de la turbine par l'intermédiaire d'un moyen de transmission de couple, par exemple un câble métallique. the electric motor, the control means and the electric supply means are arranged in a housing, the electric motor being coupled to the axis of rotation of the turbine by means of a torque transmission means, by example a wire rope.
2 5 - un capteur de pression agencé au niveau du masque ou dont la prise de pression débouche au niveau du masque coopère avec les moyens de commande en transmettant auxdits moyens de commande un signal de pression correspondant à la pression gazeuse régnant dans la coque du masque à un instant donné. 2 5 - a pressure sensor arranged at the mask or whose pressure tap opens at the mask cooperates with the control means by transmitting to said control means a pressure signal corresponding to the gas pressure prevailing in the mask shell at a given time.
La solution de l'invention consiste donc à incorporer la turbine délivrant le gaz sous 3 0 pression, et éventuellement le moteur, dans le masque. Ceci permet également de supprimer l'orifice de fuite calibré qui devient inutile du fait de la suppression du tuyau, donc du volumemort du tuyau. The solution of the invention therefore consists in incorporating the turbine delivering the gas under pressure, and possibly the engine, into the mask. This also makes it possible to remove the calibrated leak orifice which becomes unnecessary because of the removal of the pipe, therefore of the volume death of the pipe.
Pour ce faire, on utilise une turbine miniaturisée conçue pour délivrer les débits et pressions juste nécessaires pour assurer l'efficacité du traitement. To do this, a miniaturized turbine is used designed to deliver the flow rates and pressures just necessary to ensure the effectiveness of the treatment.
Dans le cadre de l'invention, le terme turbine est considéré comme équivalant du terme "soufflante". Une telle turbine comprend un capotage stationnaire dans lequel est agencée une (ou plusieurs) roue à aubes ou pales, mobile en rotation autour d'un axe de rotation sous l'effet du couple qui lui est transmis par l'axe d'entraînement d'un moteur électrique, ledit capotage comportant une bouche d'aspiration permettant l'entrée d'air dans le 10 capotage et une bouche d'expulsion d'air comprimé par laquelle ressort l'air, après élévation de sa pression dans le capotage de la turbine. In the context of the invention, the term turbine is considered to be equivalent to the term "fan". Such a turbine comprises a stationary casing in which is arranged one (or more) impeller or blades, movable in rotation around an axis of rotation under the effect of the torque which is transmitted to it by the drive axis d an electric motor, said cowling comprising a suction mouth allowing the entry of air into the cowling and a compressed air expulsion mouth through which the air comes out, after raising its pressure in the cowling of the turbine.
L'invention va être mieux comprise grâce à la description suivante donnée en références aux figures annexées. The invention will be better understood from the following description given with reference to the appended figures.
Les figures 2 et 3 représentent un schéma de principe d'un premier mode de 15 réalisation d'un dispositif selon l'invention comprenant un ensemble respiratoire formé d'un masque 11 respiratoire nasal incorporant et associé à une turbine 12. FIGS. 2 and 3 represent a block diagram of a first embodiment of a device according to the invention comprising a respiratory assembly formed by a nasal respiratory mask 11 incorporating and associated with a turbine 12.
Dans ce mode de réalisation, c'est le groupe moto-turbine 12, 13 qui est incorporé au masque 11, c'est-à-dire la turbine 12 et le moteur électrique 13 couplé à l'axe d'entraînement de la turbine 12 qui permet d'obtenir une aspiration d'air ambiant par ladite turbine 12 et son 2 0 expulsion subséquente, après compression, dans le masque 11 porté par le patient. In this embodiment, it is the motor-turbine group 12, 13 which is incorporated in the mask 11, that is to say the turbine 12 and the electric motor 13 coupled to the drive shaft of the turbine. 12 which allows a suction of ambient air by said turbine 12 and its subsequent expulsion, after compression, into the mask 11 worn by the patient.
Par ailleurs, le groupe moto-turbine 12, 13 est connecté par un câble électrique 14 à un boîtier 16' comprenant, d'une part, l'alimentation en courant électrique, et, d'autre part, les moyens de commande du moteur 13, par exemple les moyens de commande comprennent une ou plusieurs cartes électroniques. Furthermore, the motor-turbine group 12, 13 is connected by an electric cable 14 to a box 16 'comprising, on the one hand, the supply of electric current, and, on the other hand, the motor control means. 13, for example the control means comprise one or more electronic cards.
2 5 Les moyens de commande permettent d'assurer un envoi de gaz au patient afin de maintenir un niveau de pression constant pendant les phases inspiratoires et expiratoires ou alors à des niveaux de pression différents pendant les phases inspiratoires et expiratoires et ce, selon le mode de fonctionnement sélectionné par le médecin en fonction des troubles dont souffre le patient. 2 5 The control means make it possible to ensure gas is sent to the patient in order to maintain a constant pressure level during the inspiratory and expiratory phases or else at different pressure levels during the inspiratory and expiratory phases, depending on the mode. of functioning selected by the doctor according to the disorders from which the patient suffers.
Un capteur 15 de pression, nécessaire à la régulation de la pression du gaz délivré par la turbine, peut être positionné dans le masque, comme montré sur la figure 2. A pressure sensor 15, necessary for regulating the pressure of the gas delivered by the turbine, can be positioned in the mask, as shown in FIG. 2.
Toutefois, le capteur 15 de pression peut aussi être relié au boîtier 16' de commande par le câble électrique 14 ou, en variante, au boîtier de commande 16', comme montré en 5 figure 3, en étant alors relié au masque 11 par le biais d'un fin tuyau souple permettant de véhiculer la pression depuis le masque 11 jusqu'au capteur 15. However, the pressure sensor 15 can also be connected to the control box 16 ′ by the electric cable 14 or, alternatively, to the control box 16 ′, as shown in FIG. 3, by then being connected to the mask 11 by the through a thin flexible pipe allowing the pressure to be conveyed from the mask 11 to the sensor 15.
La figure 4 représente un schéma de principe d'un deuxième mode de réalisation d'un dispositif selon l'invention selon lequel seule la turbine 12 est incorporée au masque 11, le moteur 13 restant dans le boîtier 16' de commande et entraînant la turbine 12 par 10 l'intermédiaire d'un câble de transmission 18 de couple agissant sur l'axe de rotation de la turbine 12. FIG. 4 represents a block diagram of a second embodiment of a device according to the invention according to which only the turbine 12 is incorporated in the mask 11, the motor 13 remaining in the control box 16 'and driving the turbine 12 by means of a torque transmission cable 18 acting on the axis of rotation of the turbine 12.
Le capteur de pression 15 peut, comme précédemment, être situé soit sur le masque 11, soit dans le boîtier 16'. The pressure sensor 15 can, as before, be located either on the mask 11 or in the housing 16 '.
Préférentiellement, l'ensemble turbine/masque de l'invention permet de délivrer de 15 l'air à une pression de 30 hPa et un débit de 2 l/s à une pression de 10 hPa. Preferably, the turbine / mask assembly of the invention makes it possible to deliver air at a pressure of 30 hPa and a flow rate of 2 l / s at a pressure of 10 hPa.
Dans tous les cas, l'ensemble incluant le masque 11 et la turbine 12, avec ou sans moteur 13, a un poids inférieur à 1 kg. In all cases, the assembly including the mask 11 and the turbine 12, with or without motor 13, has a weight of less than 1 kg.
De façon classique, il comporte des moyens de maintien pour permettre de maintenir le masque en position sur la région nasale de l'utilisateur, notamment des sangles ou tout 2 0 autre système analogue. Conventionally, it comprises holding means to allow the mask to be held in position on the nasal region of the user, in particular straps or any other similar system.
Les figures 5 et 6 montrent des masques 11 selon la présente invention selon deux modes de réalisation possibles. Figures 5 and 6 show masks 11 according to the present invention according to two possible embodiments.
La figure 5 schématise un premier mode de réalisation selon lequel le moteur 13 de la turbine 12 est agencé en position "vers l'avant", c'est-àdire le plus éloigné possible du nez du 2 5 patient. Figure 5 shows schematically a first embodiment according to which the motor 13 of the turbine 12 is arranged in the "forward" position, that is to say as far as possible from the nose of the patient.
Comme on le voit, le masque 11, positionné sur le nez d'un patient, comprend une coque formant volume interne 23 et dimensionnée de manière à pouvoir recevoir tout ou partie de la région nasale dudit patient. As can be seen, the mask 11, positioned on the nose of a patient, comprises a shell forming an internal volume 23 and dimensioned so as to be able to receive all or part of the nasal region of said patient.
La turbine 12 incorporée directement au masque 11 comprend un capotage 19 30 stationnaire, de préférence insonorisé, dans lequel est agencée au moins une roue à aubes 20, c'est-à-dire une ou plusieurs hélices, mobile en rotation autour de l'axe de rotation du moteur 13. The turbine 12 incorporated directly into the mask 11 comprises a stationary casing 19, preferably soundproofed, in which is arranged at least one impeller 20, that is to say one or more propellers, movable in rotation around the motor rotation axis 13.
Le capotage 19 comporte, en outre, une bouche d'aspiration 21 par laquelle entre le gaz, c'est-à-dire l'air, dans le capotage 19 et une bouche d'expulsion 22 communiquant 5 fluidiquement avec l'intérieur 23 de la coque du masque 11 et par laquelle l'air sous pression est envoyé vers les voies aériennes supérieures du patient. The cowling 19 further comprises a suction mouth 21 through which the gas, that is to say the air, enters the cowling 19 and an expulsion mouth 22 communicating fluidly with the interior 23 of the shell of the mask 11 and through which the pressurized air is sent to the upper airways of the patient.
Par ailleurs, le masque 11 comporte un capteur de pression 24 agencé de manière à pouvoir mesurer la pression à l'intérieur 23 du masque 11, grâce à une prise de pression 17 adaptée. Furthermore, the mask 11 includes a pressure sensor 24 arranged so as to be able to measure the pressure inside 23 of the mask 11, thanks to a suitable pressure tap 17.
Typiquement, le moteur 13 de la turbine 12 a une vitesse de rotation maximum comprise entre environ 10 000 et 60 000 tours/minute, en général de l'ordre de 20 000 à 35 000 tr/min, le diamètre étant compris entre 30 et 60 mm. Autrement dit, l'inertie de la turbine doit être faible. Typically, the motor 13 of the turbine 12 has a maximum speed of rotation of between approximately 10,000 and 60,000 revolutions / minute, in general of the order of 20,000 to 35,000 rpm, the diameter being between 30 and 60 mm. In other words, the inertia of the turbine must be low.
Afin d'assurer une teneur en vapeur d'eau contrôlée pour éviter de dessécher les 1 5 muqueuses du patient, l'air comprimé envoyé au patient est préférentiellement humidifié au moyen d'un humidificateur 27 agencé sur le trajet du gaz entre la bouche d'aspiration 21 et la roue à aubes 20. In order to ensure a controlled water vapor content to avoid drying out the patient's mucous membranes, the compressed air sent to the patient is preferably humidified by means of a humidifier 27 arranged on the path of the gas between the mouth of the patient. 21 and the impeller 20.
Des moyens de commande 16 permettent de commander le fonctionnement de la turbine 12, via éventuellement une carte relais 28 agencée dans le masque 11. Control means 16 make it possible to control the operation of the turbine 12, optionally via a relay card 28 arranged in the mask 11.
Par ailleurs, des moyens d'alimentation électrique 25, 26 permettent d'alimenter en courant électrique le moteur 13 et/ou les moyens de commande 16, en particulier une alimentation secteur 25 et une prise basse tension 26, notamment du type prise allume-cigare ou analogue. Furthermore, electrical supply means 25, 26 make it possible to supply electric current to the motor 13 and / or the control means 16, in particular a mains supply 25 and a low voltage socket 26, in particular of the lighter socket type. cigar or the like.
Le moteur électrique 13 est porté par l'ensemble masque/turbine 11, 12 en étant 2 5 connecté aux moyens de commande 16 et aux moyens d'alimentation électrique 25, 26 par l'intermédiaire d'un ou plusieurs moyens de connexion 14, tels des câbles électriques ou analogues. The electric motor 13 is carried by the mask / turbine assembly 11, 12 while being connected to the control means 16 and to the electric supply means 25, 26 via one or more connection means 14, such as electric cables or the like.
Le moteur électrique 13 est, dans ce cas, couplé (en 18) directement à l'axe de rotation de la turbine 12. The electric motor 13 is, in this case, coupled (at 18) directly to the axis of rotation of the turbine 12.
La figure 6 schématise un deuxième mode de réalisation analogue à celui de la figure mais selon lequel le moteur 13 de la turbine 12 est, cette fois, agencé en position "vers l'arrière"; c'est-à-dire plus près du nez du patient que dans le cas précédent; les autres éléments constituants le masque sont également présents dans ce mode de réalisation et les mêmes références ont été conservées. Figure 6 shows schematically a second embodiment similar to that of the figure but according to which the motor 13 of the turbine 12 is, this time, arranged in position "backwards"; that is to say closer to the patient's nose than in the previous case; the other elements constituting the mask are also present in this embodiment and the same references have been kept.
Dans tous les cas, pour assurer un confort optimal au patient, l'ensemble de l'invention sera aussi insonorisé que possible pour diminuer au maximum les nuisances sonores mais en prenant garde à ne pas alourdir de manière excessive le poids de l'ensemble. In all cases, to ensure optimal comfort for the patient, the whole of the invention will be as soundproof as possible to reduce noise pollution as much as possible but taking care not to excessively increase the weight of the whole.
