Description

Caisson de confinement ou d'isolement d'un nouveau typeA new type of containment or isolation box
La présente invention concerne un caisson de confinement ou d'isolement portable délimitant une enceinte dimensionnée pour loger au moins une personne victime de brûlure ou d'une contamination de nature quelconque ou devant bénéficier d'une mise en surpression pour raison médicale, ledit caisson étant constitué d'au moins deux demi- coquilles assemblables de manière étanche .The present invention relates to a portable confinement or isolation box delimiting an enclosure dimensioned to accommodate at least one person who has suffered a burn or contamination of any kind or who should benefit from overpressure for medical reasons, said box being consisting of at least two half-shells which can be assembled in a leaktight manner.
Les enceintes du type décrit ci-dessus sont notamment connues par le brevet EP-A-0.17 .819 ou par le brevet EP-A- 0.002.274.The enclosures of the type described above are known in particular from patent EP-A-0.17.819 or from patent EP-A-0.002.274.
On connaît par ailleurs une seconde catégorie d'enceinte de confinement ou d'isolement se présentant sous forme d'enveloppe souple comme l'illustrent en particulier les brevets US-A-3.345.996, US-A-2.279.694 , US-A-6.001.057, DE- A-970.939 et EP-A-0.417.051. Les enveloppes souples, lorsqu'elles sont associées à un dispositif d'alimentation en air, présentent l'inconvénient de ne pouvoir fonctionner exclusivement qu'en surpression comme l'illustre en particulier le brevet EP-A-0.417.051 du fait de la présence d'une enveloppe souple associée à une vanne d'échappement, organe mécanique qui présente un certain nombre d'inconvénients. La mise en surpression de l'enceinte est particulièrement adaptée en cas de victime ayant subi de graves brûlures. A l'inverse, il est préférable de placer l'enceinte sous dépression lorsqu'une personne est contaminée. Les enceintes de sécurité connues à ce jour ne permettent pas une telle mise sous dépression dans le cas d'une enceinte portable. Par ailleurs, la présence de dispositifs de ventilation externes à l'enceinte engendre un encombrement important de 1 ' ensemble .A second category of containment or isolation enclosure is also known which is in the form of a flexible envelope as illustrated in particular by patents US-A-3,345,996, US-A-2,279,694, US- A-6.001.057, DE- A-970.939 and EP-A-0.417.051. Flexible envelopes, when associated with an air supply device, have the disadvantage of being able to operate exclusively under overpressure as illustrated in particular by patent EP-A-0,417,051 due to the presence of a flexible envelope associated with an exhaust valve, a mechanical member which has a certain number of drawbacks. The overpressure of the enclosure is particularly suitable in the case of a victim who has suffered severe burns. Conversely, it is preferable to place the enclosure under vacuum when a person is contaminated. The safety enclosures known to date do not allow such vacuuming in the case of a portable enclosure. Furthermore, the presence of ventilation devices external to the enclosure generates a large overall size of the assembly.
Un but de la présente invention est donc de proposer un caisson de confinement ou d'isolement d'un nouveau type dont la conception permet indifféremment la mise sous dépression ou en surpression de l'enceinte sans nuire à l'encombrement du caisson demeurant aisément portable. Un autre but de la présente invention est de proposer un caisson de confinement ou d'isolement d'un nouveau type dont la conception permet deux modes de fonctionnement, respectivement en dépression ou en surpression au moyen d'une même turbine, le passage d'un fonctionnement à un ' autre s ' effectuant en quelques minutes .An object of the present invention is therefore to propose a containment or isolation box of a new type, the design of which makes it possible either to place the enclosure under vacuum or in overpressure without affecting the bulk of the box, which remains easily portable. . Another object of the present invention is to propose a containment or isolation box of a new type, the design of which allows two modes of operation, respectively under vacuum or under pressure by means of the same turbine, the passage of operation to the other being performed in minutes.
Un autre but de la présente invention est de proposer un caisson de confinement ou d'isolement portable dont la. conception permet une décontamination aisée de l'ensemble.Another object of the present invention is to propose a portable confinement or isolation box, the. design allows easy decontamination of the whole.
Un autre but de la présente invention est de proposer un caisson de confinement ou d'isolement portable dont la conception permet d'éviter l'incorporation de valves ou de vannes d'échappement mécaniques ou tout autre type d'organes mécaniques nécessaires à l'évacuation de l'air contenu à 1 ' intérieur de ladite enceinte .Another object of the present invention is to propose a portable containment or isolation box whose design makes it possible to avoid the incorporation of mechanical exhaust valves or any other type of mechanical organs necessary for the evacuation of the air contained within said enclosure.
A cet effet, l'invention a pour objet un caisson de confinement ou d'isolement portable délimitant une enceinte dimensionnée pour loger au moins une personne victime de brûlure ou d'une contamination de nature quelconque, ledit caisson étant constitué d'au moins deux demi-coquilles assemblables de manière étanche, caractérisé en ce qu'au moins l'une des demi-coquilles est munie en un emplacement prédéterminé d'un bloc technique autonome renfermant au moins une turbine couplée à une alimentation intérieure ou extérieure audit bloc, ce bloc technique étant apte à communiquer d'une part avec l'atmosphère extérieure, d'autre part avec l'atmosphère de l'enceinte du caisson par l'intermédiaire d'au moins deux ouvertures connectables audit caisson, au moins l'une des ouvertures dudit bloc technique étant apte à servir indifféremment d'alimentation en air de l'enceinte du caisson ou de sortie d'air de l'enceinte du caisson, en fonction du mode de fonctionnement souhaité dudit caisson pour permettre indifféremment la mise sous dépression ou en surpression de l'enceinte du caisson, au moins un filtre étant à chaque fois positionné sur le trajet de circulation de l'air entre caisson et bloc. ' Selon un premier mode de réalisation de l'invention, l'ouverture du bloc, apte à servir indifféremment d'ouverture d'alimentation en air de l'enceinte du caisson ou de sortie d'air de l'enceinte du caisson est, en mode surpression du caisson, connectée à une ouverture d'une demi-coquille du caisson et constitue une ouverture d'alimentation en air de l'enceinte du caisson tandis qu'en mode dépression du caisson, elle est déconnectée de ladite ouverture d'une demi-coquille du caisson et constitue une ouverture de sortie d'air de l'enceinte du caisson.To this end, the subject of the invention is a portable confinement or isolation box delimiting an enclosure sized to accommodate at least one person who has suffered a burn or contamination of any kind, said box consisting of at least two tightly assembled half-shells, characterized in that at least one of the half-shells is provided at a predetermined location with an autonomous technical block containing the minus one turbine coupled to an internal or external power supply to said block, this technical block being able to communicate on the one hand with the external atmosphere, on the other hand with the atmosphere of the enclosure of the box through at least two openings connectable to said box, at least one of the openings of said technical unit being able to serve either air supply to the enclosure of the box or air outlet from the enclosure of the box, depending on the desired mode of operation of said box to allow either the vacuuming or overpressure of the enclosure of the box, at least one filter being each time positioned on the air circulation path between box and block. 'According to a first embodiment of the invention, the opening of the block, capable of serving as air supply opening regardless of the enclosure of the box or air outlet of the enclosure of the box is, in overpressure mode of the box, connected to an opening of a half-shell of the box and constitutes an air supply opening of the enclosure of the box while in depression mode of the box, it is disconnected from said opening a half-shell of the box and constitutes an air outlet opening of the enclosure of the box.
Grâce à cette conception du bloc technique, la commutation ou passage d'un mode de fonctionnement en dépression à un mode de fonctionnement en surpression du caisson s'effectue par simple connexion d'une des ouvertures du bloc avec l'atmosphère de l'enceinte du caisson et fermeture de la communication du bloc avec l'atmosphère extérieure tandis que la commutation du mode surpression en mode dépression s'effectue par simple déconnexion d'une des ouvertures du bloc avec l'atmosphère de l'enceinte du caisson et ouverture de la communication du bloc avec l'atmosphère extérieure. Il en résulte une possibilité de passer d'un mode de fonctionnement à un autre en quelques minutes. Selon un second mode de réalisation de l'invention, les ouvertures du bloc technique servent indifféremment l'une d'alimentation en air de l'enceinte du caisson et l'autre de sortie d'air de l'enceinte du caisson en fonction du sens de circulation d'air imposé par la turbine pour permettre indifféremment la mise sous dépression ou en surpression de l'enceinte.Thanks to this design of the technical unit, the switching or transition from an operating mode in vacuum to an operating mode in overpressure of the box is carried out by simple connection of one of the openings of the unit with the atmosphere of the enclosure. of the box and closing of the block's communication with the outside atmosphere while switching from overpressure mode to vacuum mode is effected by simple disconnection of one of the block openings with the atmosphere of the box enclosure and opening of the block's communication with the outside atmosphere. This results in a possibility of switching from one operating mode to another in a few minutes. According to a second embodiment of the invention, the openings of the technical unit indifferently serve one for air supply to the enclosure of the box and the other for air outlet from the enclosure of the box depending on the direction of air flow imposed by the turbine to allow either the vacuum or overpressure of the enclosure.
Dans un second mode de réalisation, du fait de la conception du caisson de confinement, le bloc technique "sert d'interface exclusive entre l'atmosphère extérieure et l'enceinte à l'état fermé de l'enceinte. Il en résulte la possibilité de permettre indifféremment la mise sous dépression ou en surpression de l'enceinte en fonction du sens de circulation d'air choisi au niveau de la ou des turbine (s) du bloc technique autonome.In a second embodiment, due to the design of the containment box, the technical unit " serves as the exclusive interface between the external atmosphere and the enclosure in the closed state of the enclosure. This results in the possibility allow either the vacuum or overpressure of the enclosure depending on the direction of air circulation chosen at the level of the turbine (s) of the autonomous technical unit.
L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels : la figure 1 représente une vue schématique à l'état ouvert d'un caisson conforme à l'invention, le bloc technique étant démonté du caisson ; la figure 2 représente une vue schématique partielle en coupe d'un bloc technique équipant un caisson conforme à 1 ' invention en mode dépression dudit caisson et la figure 3 représente une vue schématique partielle en coupe d'un bloc technique équipant un caisson conforme à 1 ' invention en mode surpression dudit caisson.The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the accompanying drawings in which: FIG. 1 represents a schematic view in the open state of a box according to the invention, the technical block being removed from the box; 2 shows a partial schematic sectional view of a technical unit equipping a box according to one invention in depression mode of said box and Figure 3 shows a partial schematic view in section of a technical unit fitted to a box according to the invention in overpressure mode of said box.
Le caisson de confinement ou d'isolement, objet de l'invention, et représenté sous la référence générale 1, délimite une enceinte IC dimensionnée pour loger au moins une personne victime de brûlure ou d'une contamination de nature quelconque. Ce caisson 1 est constitué d'au moins deux demi-coquilles 1A, IB assemblables de manière étanche par un plan de joint incorporant des moyens d'êtanchéité. Chaque demi-coquille peut être réalisée sous forme d'une pièce moulée en un matériau permettant une décontamination aisée. La demi-coquille inférieure, représentée en 1A aux figures, présente une rigidité suffisante pour permettre le portage de l'ensemble. La demi-coquille IB supérieure peut comporter au moins une fenêtre de visualisation de l'intérieur de l'enceinte. Cette fenêtre peut être réalisée au moyen d'un matériau souple transparent ou d'un matériau rigide transparent. Il peut être également prévu d'utiliser- ces deux demi-coquilles 1A, IB sous forme d'éléments à usage unique de manière à constituer un ensemble jetable après transport d'une victime.The confinement or isolation box, object of the invention, and represented under the general reference 1, delimits an enclosure IC dimensioned to accommodate at least one person who has suffered a burn or contamination of any kind. This box 1 consists of at least two half-shells 1A, IB which can be assembled in a sealed manner by a joint plane incorporating sealing means. Each half-shell can be produced in the form of a part molded from a material allowing easy decontamination. The lower half-shell, shown at 1A in the figures, has sufficient rigidity to allow the assembly to be carried. The upper half-shell IB may include at least one window for viewing the interior of the enclosure. This window can be made using a transparent flexible material or a transparent rigid material. It can also be provided to use these two half-shells 1A, IB in the form of single-use elements so as to constitute a disposable assembly after transporting a victim.
De manière caractéristique à l'invention, au moins l'une IB des demi-coquilles 1A, IB est munie d'un bloc 2 technique autonome . Ce bloc 2 technique autonome renferme au moins une turbine 3, tel qu'un ventilateur, couplée à une alimentation 4 logée à l'intérieur ou à l'extérieur dudit bloc 2. Cette alimentation comporte au moins une batterie destinée à l'alimentation d'un moteur servant au fonctionnement de la turbine 3. Afin de ne pas augmenter l'encombrement de l'ensemble, au moins l'une des de i- coquilles, de préférence la demi-coquille IB supérieure du caisson 1, est munie en un emplacement déterminé d'une réservation 11 pour la réception du bloc 2 technique autonome. Il en résulte la possibilité d'inscrire le bloc technique dans le volume général de 1 ' enceinte du caisson de manière à ne pas augmenter l'encombrement de ce dernier. Ce bloc 2 technique, assemblable de manière hermétique à la demi-coquille 1A munie d'une réservation, comporte au moins deux ouvertures 5A, 5B pour permettre une communication du volume délimité par le bloc 2 avec l'atmosphère de l'enceinte IC du caisson 1. Au moins l'une des ouvertures du bloc technique est apte à servir indifféremment d'alimentation en air de l'enceinte IC du caisson ou de sortie d'air de l'enceinte IC du caisson en fonction du mode de fonctionnement souhaité du caisson pour permettre indifféremment la mise sous dépression ou en surpression de l'enceinte IC du caisson. Ainsi, dans les exemples représentés, l'ouverture 5B du bloc 2 constitue l'ouverture apte à servir indifféremment d'ouverture d'alimentation en air de l'enceinte IC du caisson 1 depuis le bloc '2 technique ou de sortie d'air de l'enceinte IC du caisson 1. Dans l'exemple représenté à la figure 2, correspondant au mode dépression du caisson, l'ouverture 5B du bloc 2 est déconnectée de l'ouverture 10B de la demi-coquille IB de caisson munie d'une réservation et constitue une ouverture de sortie d'air de l'enceinte du caisson 1. Ainsi, l'air entre à travers une première ouverture représentée en 10B aux figures à 1 ' intérieur du caisson sous 1 ' effet de la turbine 3 et ressort de ce caisson à travers une ouverture représentée en 10A, correspondant à l'ouverture 5A du bloc technique avant de sortir du bloc 2 technique par l'ouverture 5B du bloc 2. Cette même ouverture 5B du bloc 2 constitue une ouverture d'alimentation en air de l'enceinte IC du caisson en mode surpression du caisson lorsque cette ouverture est connectée à l'ouverture 10B de la de i- coquille IB du caisson. Cette ouverture 5B du bloc 2 est connectable, de manière déconnectable, à l'ouverture 10B ménagée dans la demi-coquille IB du caisson munie d'une réservation 11, directement ou par l'intermédiaire d'un raccord, tel qu'une manche 7 à air, au moins partiellement démontable. Au moins un filtre 8B équipe l'une ou l'autre desdites ouvertures 5B, 10B du bloc technique ou respectivement du caisson. De préférence, le filtre 8B équipe l'ouverture 10B ménagée sur la demi-coquille IB du caisson 1. Dans tous les cas, au moins un filtre 8A, 8B est à chaque fois positionné sur le trajet de circulation de l'air entre caisson 1 et bloc 2. Comme l'illustre la figure 2, en mode dépression, l'air pénètre dans l'enceinte du caisson à travers l'ouverture 10B ménagée sur la face verticale de la réservation 11 correspondant à un encochage ménagée dans la demi-coquille supérieure dudit caisson. Cet ' air est amené à circuler à l'intérieur dudit caisson avant de ressortir de ce caisson à travers l'ouverture 10A du caisson ménagé sur une paroi horizontale dudit caisson. Cette ouverture 10A correspond avec l'ouverture 5A du blô'c technique. L'air pénètre alors dans le bloc technique avant d'être évacué de ce bloc à travers l'ouverture 5B dudit bloc qui permet un échappement à l'air libre de l'air contenu dans ledit caisson et aspiré par la turbine 3. En mode surpression, l'ouverture 5B du bloc 2 technique est connectée à l'ouverture 10B du caisson, qui constitue en mode dépression l'ouverture d'entrée d'air dans le caisson, par l'intermédiaire d'une manche à air 7. Ainsi, la turbine 3 continue à aspirer l'air contenu à l'intérieur du caisson par 1 ' intermédiaire des ouvertures 5A et 10A et le souffle à travers l'ouverture 5B mise en communication avec l'ouverture 10B du caisson. Ce caisson fonctionne alors en mode surpression et est alimente en air depuis le bloc 2 technique par 1 ' intermédiaire de 1 ' ouverture 5B du bloc .Characteristically with the invention, at least one IB of the half-shells 1A, IB is provided with an autonomous technical unit 2. This autonomous technical block 2 contains at least one turbine 3, such as a fan, coupled to a power supply 4 housed inside or outside said block 2. This power supply comprises at least one battery intended for the supply of 'a motor for the operation of the turbine 3. In order not to increase the size of the assembly, at least one of the i-shells, preferably the upper half-shell IB of the box 1, is provided with a specific location of a reservation 11 for the reception of autonomous technical block 2. This results in the possibility of inscribing the technical unit in the general volume of the enclosure of the box so as not to increase the size of the latter. This technical block 2, which can be assembled hermetically to the half-shell 1A provided with a reservation, comprises at least two openings 5A, 5B to allow communication of the volume delimited by block 2 with the atmosphere of the enclosure IC of the box 1. At least one of the openings in the technical unit is suitable for serving either the air supply to the enclosure IC of the box or the air outlet from the enclosure IC of the box depending on the desired operating mode of the box to allow either the vacuum or overpressure of the enclosure IC of the box. Thus, in the examples shown, the opening 5B of the block 2 constitutes the opening capable of serving equally as an opening for supplying air to the enclosure IC of the box 1 from the technical block 2 or for air outlet of the enclosure IC of the box 1. In the example shown in FIG. 2, corresponding to the depression mode of the box, the opening 5B of the block 2 is disconnected from the opening 10B of the half-shell IB of the box provided with 'a reservation and constitutes an air outlet opening of the enclosure of the box 1. Thus, the air enters through a first opening shown in 10B in the figures inside the box under the effect of the turbine 3 and spring of this box through an opening shown in 10A, corresponding to the opening 5A of the technical block before leaving the technical block 2 through the opening 5B of the block 2. This same opening 5B of the block 2 constitutes an opening of air supply to the IC enclosure enclosure in purple mode ssion of the box when this opening is connected to the opening 10B of the i-shell IB of the box. This opening 5B of the block 2 is connectable, in a disconnectable manner, to the opening 10B formed in the half-shell IB of the box provided with a reservation 11, directly or via a fitting, such as an air sleeve 7, at least partially removable. At least one filter 8B equips one or the other of said openings 5B, 10B of the technical unit or respectively of the box. Preferably, the filter 8B equips the opening 10B formed on the half-shell IB of the box 1. In all cases, at least one filter 8A, 8B is each time positioned on the air circulation path between the box 1 and block 2. As illustrated in FIG. 2, in vacuum mode, the air enters the enclosure of the box through the opening 10B made on the vertical face of the reservation 11 corresponding to a notch made in the half - upper shell of said box. This air is circulated within said chamber before exiting from said box through the opening 10A of the casing provided on a horizontal wall of said housing. This opening 10A corresponds with the opening 5A of the technical block. The air then enters the technical block before being evacuated from this block through the opening 5B of said block which allows the air contained in said box to be escaped into the open air and sucked in by the turbine 3. In overpressure mode, the opening 5B of the technical block 2 is connected to the opening 10B of the box, which constitutes in vacuum mode the air inlet opening in the box, by means of an air sleeve 7 Thus, the turbine 3 continues to suck the air contained inside the box through the openings 5A and 10A and blows it through the opening 5B placed in communication with the opening 10B of the box. This box then operates in overpressure mode and is supplied with air from the technical block 2 through the opening 5B of the block.
Pour permettre un tel fonctionnement, un apport en air neuf est nécessaire. A cet effet, le bloc 2 technique communique avec l'atmosphère extérieure par l'intermédiaire d'au moins un orifice 6 obturable à ouverture ajustable, ledit orificeTo allow such operation, a supply of fresh air is necessary. To this end, the technical block 2 communicates with the external atmosphere via at least one closable orifice 6 with adjustable opening, said orifice
6 étant obturé en mode dépression du caisson 1 et ouvert en mode surpression du caisson 1. L'amplitude de l'ouverture de l'orifice 6 est réglable et est fonction du niveau de surpression souhaité.6 being closed in depression mode of the box 1 and open in overpressure mode of the box 1. The amplitude of the opening of the orifice 6 is adjustable and is a function of the desired level of overpressure.
L'ouverture 5A du bloc 2 technique apte à communiquer avec l'atmosphère intérieure de l'enceinte du caisson 1 par l'intermédiaire de l'ouverture 10A ménagée dans la demi- coquille IB du caisson munie d'une réservation constitue quant à elle exclusivement une ouverture 5A de sortie d'air de 1 ' enceinte IC du caisson 1 indépendamment du mode de fonctionnement en surpression ou en dépression du caisson 1. Grâce à cette disposition des différentes ouvertures, on constate que le passage d'un mode de fonctionnement à un autre du caisson s'effectue d'une part par simple connexion ou respectivement déconnexion d'une des ouvertures du bloc', en l'occurrence l'ouverture 5B du bloc, avec l'atmosphère de l'enceinte du caisson par l'intermédiaire dé l'ouverture 10B ménagée dans ledit caisson, d'autre part par fermeture ou respectivement ouverture de la communication 6 du bloc 2 technique avec l'atmosphère extérieure. Pour faciliter la connexion et la déconnexion de telles ouvertures, au moins l'un des filtres 8A, 8B est pré-monté sur l'une des ouvertures de l'une des demi-coquilles 1A, IB du caisson 1, en l'occurrence la demi-coquille supérieure IB du caisson équipée des ouvertures 10A, 10B servant au raccordement de l'atmosphère de l'enceinte du caisson avec le bloc 2 technique ou avec l'extérieur.The opening 5A of the technical block 2 capable of communicating with the interior atmosphere of the enclosure of the box 1 by means of the opening 10A formed in the half-shell IB of the box provided with a reservation constitutes, for its part exclusively an opening 5A for the air outlet of the enclosure IC of the box 1 independently of the operating mode under overpressure or under vacuum of the box 1. Thanks to this arrangement of the different openings, it can be seen that the passage from an operating mode to another of the box is made on the one hand by simple connection or respectively disconnection of one of the block openings ' , in this case the opening 5B of the block, with the atmosphere of the box enclosure by the through the opening 10B made in said box, on the other hand by closing or respectively opening the communication 6 of the technical block 2 with the external atmosphere. To facilitate the connection and disconnection of such openings, at least one of the filters 8A, 8B is pre-mounted on one of the openings of one of the half-shells 1A, IB of the box 1, in this case the upper half-shell IB of the box equipped with the openings 10A, 10B serving to connect the atmosphere of the enclosure of the box with the technical block 2 or with the outside.
Le passage d'un mode de fonctionnement à un autre peut s'opérer parallèlement à un repositionnement du bloc technique. En effet, le bloc technique est monté de manière amovible sur l'une des demi-coquilles 1A, IB, en l'occurrence à nouveau sur la demi-coquille supérieure IB. Ce bloc 2 technique présente, comme l'illustrent les figures 2 et 3, au moins deux positions de raccordement à une même ouverture 10A de l'enceinte du caisson en fonction du rôle joué par son ouverture 5B apte à servir indifféremment d'alimentation en air de l'enceinte IC du caisson ou de sortie d'air de l'enceinte IC du caisson. En effet, lors du passage du mode dépression à un mode surpression ou inversement, le bloc technique peut être pivoté autour de son axe de 180° ou repositionné sur l'ouverture 10A pour permettre à l'ouverture 5B de ne plus être positionnée en regard de l'ouverture 10B de l'enceinte du caisson à laquelle elle est connectée en mode surpression. Ainsi, l'air s 'échappant de l'ouverture 5B en ' mode dépression du caisson ne vient pas perturber l'admission d'air dans ledit caisson, cette admission s Opérant par l'intermédiaire de l'ouverture 10B ménagée dans ledit caisson. Dans les exemples représentés, le bloc 2 technique est- monté sur la demi-coquille IB dite supérieure de l'enceinte à une extrémité de cette dernière de manière à être positionné, à l'état fermé de l'enceinte, au-dessus de l'emplacement correspondant à celui occupé par les pieds de la victime. Ce bloc technique délimite au moins une chambre et loge une turbine 3. Cette turbine assure une circulation d'air à l'intérieur de l'enceinte du caisson 2. Cette turbine comporte au moins une entrée 3A d'admission d'air dans la turbine 3 et une sortie 3B d'échappement d'air de ladite turbine 3. La sortie 3B d'échappement d'air coopère à la délimitation de l'ouverture 5B du bloc 2 servant indifféremment d'alimentation en air de l'enceinte du caisson ou de sortie d'air de l'enceinte du caisson. L'entrée 3A de la turbine est quant à elle disposée dans la chambre ménagée par ledit bloc 2. Cette chambre est munie d'une part d'au moins une ouverture 5A raccordable à l'atmosphère intérieure du caisson pour constituer l'ouverture de sortie d'air du caisson, d'autre part d'une ouverture 6 obturable communiquant avec 1 ' atmosphère extérieure . Cette turbine 3 est une turbine à débit variable qui peut être commandée en fonctionnement à partir d'informations fournies par des sondes 9A, 9B de pression, placées de préférence l'une, 9B, dans l'enceinte IC du caisson 1, l'autre, 9A, dans le bloc 2 technique. Sur le trajet de circulation de l'air entre caisson et bloc, il est prévu à chaque fois un filtre représenté en 8A, 8B aux figures. Ces filtres 8A, 8B, équipant les ouvertures 5A, 5B ou 10A, 10B de communication du bloc 2 avec l'enceinte du caisson, présentent des pertes de charge différenciées. - Comme l'illustrent les figures, dans les exemples représentés, les ouvertures 5A, 5B de communication du bloc 2 avec l'enceinte IC du caisson délimitent des surfaces sensiblement orthogonales entre elles. L'une 5B des ouvertures 5A, 5B de communication du bloc 2 avec l'enceinte IC communique avec ladite enceinte par l'intermédiaire d'une ouverture 10B de l'enceinte ménagée sur une paroi de la demi-coquille supérieure du caisson s ' étendant transversalement à 1 ' axe longitudinal de l'enceinte de manière à former, à l'intérieur de l'enceinte, un flux d'air balayant la paroi du dessus de la demi-coquille IB supérieure. Cette paroi du dessus de la demi-coquille supérieure est ainsi munie d'une fenêtre 12 pour la visualisation de l'intérieur de l'enceinte IC délimitée par le caisson. Cette paroi transversale " de la demi-coquille supérieure constitue une paroi dite verticale participant à la réalisation de la réservation 11 ménagée dans la demi-coquille. Un balayage constant permet d'éviter toute condensation à la surface de la fenêtre qui équipe la demi-coquille IB supérieure du caisson pour permettre en toute circonstance la visualisation de l'intérieur de l'enceinte délimitée par le caisson indépendamment du mode de fonctionnement du caisson. Par ailleurs et de manière en soi connue, au moins la demi- coquille inférieure 1A du caisson présente des poignées de manutention permettant le portage de l'ensemble ainsi que des anneaux permettent 1 'hélitreuillage de l'ensemble. La fixation des demi-coquilles l'une à l'autre peut être assurée par des grenouillères. Des gants de manipulation pour une intervention sur le patient et des dispositifs étanches pour d'une part le passage d'une perfusion, d'autre part pour l'amenée d'oxygène ou le passage d'alimentation liquide ainsi que d'autres connexions 'peuvent être prévus dans l'une des demi-coquilles . Il peut être envisagé, à titre d'option, un dispositif autorisant la communication par interphone de la victime avec l'extérieur, l'incorporation d'un dispositif de production de sons tel qu'un lecteur CD, une radio ou un lecteur de cassettes pour augmenter le confort de la victime.The transition from one operating mode to another can take place in parallel with a repositioning of the technical block. Indeed, the technical unit is removably mounted on one of the half-shells 1A, IB, in the occurrence again on the upper half-shell IB. This technical block 2 has, as illustrated in FIGS. 2 and 3, at least two positions for connection to the same opening 10A of the enclosure of the box depending on the role played by its opening 5B capable of serving equally as a supply for air from the IC enclosure of the enclosure or air outlet from the IC enclosure of the enclosure. In fact, when switching from vacuum mode to overpressure mode or vice versa, the technical unit can be pivoted about its axis by 180 ° or repositioned on the opening 10A to allow the opening 5B to no longer be positioned opposite the opening 10B of the enclosure of the box to which it is connected in overpressure mode. Thus, the air s escaping the aperture 5B 'depression mode box does not disturb the air inlet in said casing, the admission s Operating through the opening 10B formed in said housing . In the examples shown, the technical block 2 is mounted on the so-called upper half-shell IB of the enclosure at one end of the latter so as to be positioned, in the closed state of the enclosure, above the location corresponding to that occupied by the victim's feet. This technical block delimits at least one chamber and houses a turbine 3. This turbine ensures air circulation inside the enclosure of the box 2. This turbine has at least one inlet 3A for admitting air into the turbine 3 and an air exhaust outlet 3B of said turbine 3. The air exhaust outlet 3B cooperates in the delimitation of the opening 5B of the block 2 serving indifferently for supplying air to the enclosure of the box or air outlet from the box enclosure. The turbine inlet 3A is disposed in the chamber formed by said block 2. This chamber is provided on the one hand at least one opening 5A connectable to the interior atmosphere of the box to constitute the air outlet opening of the box, on the other hand of a closable opening 6 communicating with one outside atmosphere. This turbine 3 is a variable flow turbine which can be controlled in operation from information supplied by pressure probes 9A, 9B, preferably placed one, 9B, in the enclosure IC of the box 1, the other, 9A, in technical block 2. On the air circulation path between the box and the block, there is provided each time a filter shown in 8A, 8B in the figures. These filters 8A, 8B, equipping the openings 5A, 5B or 10A, 10B for communication of the block 2 with the enclosure of the box, have differentiated pressure drops. - As illustrated in the figures, in the examples shown, the openings 5A, 5B for communication of block 2 with the enclosure IC of the box delimit surfaces substantially orthogonal to each other. One 5B of the openings 5A, 5B of communication of the block 2 with the enclosure IC communicates with said enclosure via an opening 10B of the enclosure formed on a wall of the upper half-shell of the box s' extending transversely to the longitudinal axis of the enclosure so as to form, inside the enclosure, a flow of air sweeping the top wall of the upper half-shell IB. This top wall of the upper half-shell is thus provided with a window 12 for viewing the interior of the enclosure IC delimited by the box. This transverse wall " of the upper half-shell constitutes a so-called vertical wall participating in the production of the reservation 11 formed in the half-shell. A constant sweeping makes it possible to avoid any condensation on the surface of the window which equips the half-shell. upper shell IB of the box to allow any circumstance the visualization of the interior of the enclosure delimited by the box independently of the operating mode of the box. Furthermore and in a manner known per se, at least the lower half-shell 1A of the box has handling handles allowing the assembly to be carried as well as rings allowing the helicopter to be hoisted from the assembly. The attachment of the half-shells to one another can be ensured by latches. Gloves of manipulation for an intervention on the patient and waterproof devices for on the one hand the passage of an infusion, on the other hand for the oxygen supply or the liquid supply passage as well as other connections ' can be provided in one of the half-shells. It is possible, as an option, to envisage a device authorizing communication by intercom of the victim with the outside, the incorporation of a sound production device such as a CD player, a radio or a music player. cassettes to increase the comfort of the victim.
De manière plus détaillée, le bloc 2 technique peut être composé d'un bloc de ventilation à haute pression disponible. Le système de filtration utilisé incorpore quant à lui des filtres à haute efficacité. La batterie est quant à elle une batterie autonome avec transformateur, un système de régulation électronique étant également prévu. Le système de filtration peut donc être constitué de filtres à haute efficacité dite HEPA (High Efficiency Particulate Air) ou ULPA (Ultra Low Pénétration Air) , cette classification étant définie par la norme EN1822.In more detail, the technical block 2 can be composed of a high pressure ventilation block available. The filtration system used incorporates high efficiency filters. The battery is an autonomous battery with transformer, an electronic regulation system also being provided. The filtration system can therefore consist of high efficiency filters called HEPA (High Efficiency Particulate Air) or ULPA (Ultra Low Penetration Air), this classification being defined by standard EN1822.
La ventilation, assurée par un ventilateur centrifuge à haute pression disponible et à compensation de charge, présente un faible niveau sonore. Le débit d'air peut être de l'ordre de 50 m3/heure soit un taux de brassage nettement supérieur à 50. La vitesse d'air est de préférence inférieure à 1,5 m/s. Bien évidemment, les matériaux constitutifs du caisson sont également prévus pour présenter une résistance au feu.The ventilation, provided by a high pressure centrifugal fan available and with load compensation, has a low noise level. The air flow can be of the order of 50 m 3 / hour, that is to say a mixing rate clearly greater than 50. The air speed is preferably less than 1.5 m / s. Obviously, the constituent materials of the box are also provided to have a fire resistance.
Enfin, des organes de visualisation du fonctionnement peuvent être prévus sur l'une quelconque des demi-coquilles ou du bloc technique et sont constitués notamment d'un manomètre, d'un dispositif de contrôle du fonctionnement de la batterie et d'un organe marche/arrêt . Le bloc technique peut ainsi être muni d'au moins un dispositif d'alarme se déclenchant en cas d'arrêt du fonctionnement de la turbine ' 3.Finally, operating display members can be provided on any one of the half-shells or of the technical unit and consist in particular of a pressure gauge, a device for controlling the operation of the battery and a running member. / stop. The equipment compartment can thus be provided with at least one alarm device that fires when stopping the operation of the turbine '3.
La conception d'un tel ensemble permet également de remplacer les demi-coquilles sans avoir à remplacer le blάc technique ou vice-versa. Il en résulte une facilité de décontamination de l'ensemble et une maintenance aisée de* 1 ' ensemble .The design of such an assembly also makes it possible to replace the half-shells without having to replace the technical block or vice versa. This results in ease of decontamination of the assembly and easy maintenance of the assembly.
Dans un autre mode de réalisation non représenté, le bloc 2 technique comporte toujours au moins deux ouvertures 5A, 5B. Dans ce cas, toutefois, les ouvertures 5A, 5B servent indifféremment l'une d'alimentation en air de l'enceinte du caisson et l'autre de sortie d'air de l'enceinte du caisson notamment en fonction du sens de circulation d'air imposé par la turbine 3 pour permettre indifféremment la mise sous dépression ou en surpression de l'enceinte IC du caisson. Ainsi, le bloc technique peut délimiter, . par l'intermédiaire d'une cloison, au moins deux chambres communiquant chacune d'une part avec l'environnement extérieur à 1 ' enceinte par 1 ' intermédiaire d ' au moins une ouverture telle que des ouies, d'autre part avec l'atmosphère de l'enceinte par l'intermédiaire d'au moins une ouverture 5A, 5B éventuellement munie de filtres. Dans ce cas, au moins l'une des chambres loge au moins la turbine et éventuellement son alimentation. Cette turbine assure la circulation d'air entre les chambres du bloc technique par passage à travers l'enceinte du caisson. Ainsi, lorsque l'enceinte du caisson doit être placée en dépression, l'ouverture par exemple 5B de l'une des chambres du bloc technique sert d ' entrée d ' air tandis que l'autre ouverture 5A sert de sortie d'air de l'enceinte. A l'inverse, lors d'un fonctionnement en surpression de l'enceinte, c'est l'ouverture 5A qui sert d'entrée d'air tandis que l'ouverture 5B sert de sortie d'air. La mise en dépression ou en surpression de l'enceinte est assurée uniquement par 1 ' inversion du sens de soufflage de la turbine 3. Cette inversion peut être obtenue par simple retournement de la turbine 3 à l'intérieur du bloc 2 technique ou par ajout d'une turbine supplémentaire logée à 1 ' intérieur du bloc 2 technique ou encore par inversion du sens de rotation de la turbine.In another embodiment not shown, the technical block 2 always includes at least two openings 5A, 5B. In this case, however, the openings 5A, 5B serve indifferently one for the air supply to the enclosure of the box and the other for the air outlet from the enclosure of the box, in particular depending on the direction of circulation d air imposed by the turbine 3 to allow either the vacuum or overpressure of the enclosure IC of the box. Thus, the technical block can delimit,. by means of a partition, at least two chambers each communicating on the one hand with the external environment to the enclosure by means of at least one opening such as louvers, on the other hand with the atmosphere of the enclosure via at least one opening 5A, 5B possibly provided with filters. In this case, at least one of the chambers houses at least the turbine and possibly its power supply. This turbine ensures the circulation of air between the chambers of the technical unit by passage through the enclosure of the box. Thus, when the enclosure of the box must be placed under vacuum, the opening for example 5B of one of the chambers of the technical unit serves as an air inlet while the other opening 5A serves as an air outlet for the enclosure. Conversely, during an overpressure operation of the enclosure, it is the opening 5A which serves as an air inlet while the opening 5B serves as an air outlet. The enclosure is placed under vacuum or over pressure only by reversing the direction of blowing of the turbine 3. This reversal can be obtained by simply reversing the turbine 3 inside the technical block 2 or by adding an additional turbine housed inside the technical block 2 or by reversing the direction of rotation of the turbine.
Pour permettre un tel fonctionnement en dépression ou en surpression de l'ensemble en fonction du sens de circulation d'air imposé par la turbine 3, les filtres équipant les ouvertures 5A, 5B de communication du bloc 2 avec l'enceinte IC du caisson présentent des pertes de charge différenciées. Il est ainsi possible de s'affranchir de tout organe mécanique tel que des vannes d'échappement malgré la possibilité de placer l'enceinte en dépression ou en surpression. Dans ce cas, la circulation s'opère à l'intérieur de l'enceinte IC placée en dépression ou en surpression par 1 ' intermédiaire du bloc 2 technique qui sert d'interface exclusive entre l'atmosphère de l'enceinte et l'atmosphère extérieure. La communication du bloc technique avec l'atmosphère extérieure s'effectue par l'intermédiaire d'ouies.To allow such operation in vacuum or in overpressure of the assembly as a function of the direction of air circulation imposed by the turbine 3, the filters equipping the openings 5A, 5B for communication of the block 2 with the enclosure IC of the box have differentiated pressure drops. It is thus possible to dispense with any mechanical member such as exhaust valves despite the possibility of placing the enclosure under vacuum or over pressure. In this case, the circulation takes place inside the enclosure IC placed in depression or in overpressure by means of the technical block 2 which serves as an exclusive interface between the atmosphere of the enclosure and the atmosphere exterior. The communication of the technical unit with the outside atmosphere is carried out by through gills.
On note qu'indépendamment du mode de réalisation, les manipulations du bloc technique pour passer d'un mode de fonctionnement à un autre du caisson sont extrêmement simples, le bloc étant reconnecté à au moins une même ouverture de l'enceinte du caisson après passage d'un mode de fonctionnement à un autre. It should be noted that, independently of the embodiment, the manipulations of the technical block to switch from one operating mode to another of the box are extremely simple, the block being reconnected to at least one same opening of the box enclosure after passage from one operating mode to another.
