Abstract
Description
La présente invention a trait à la conception d'une armoire pour la bio décontamination de l'air des salles d'opération.The present invention relates to the design of a cabinet for bio-decontamination of the air in operating rooms.
L'air est l'élément invisible d'une salle d'opération dont il ne faut pas négliger la qualité bactériologique. Le niveau de concentration en micro organisme y est élevé et cet état représente un danger pour l'opéré et l'équipe chirurgicale. Pour limiter les risques d'infections dans les salles d'opération, il est nécessaire de disposer d'un produit ayant la capacité de remplir un certain nombre de fonctions essentielles pour le milieu ambiant de ces salles:
Evacuation et suppression au maximum des particules contenues dans l'air.Air is the invisible element of an operating room, the bacteriological quality of which must not be overlooked. The level of microorganism concentration is high and this state represents a danger for the patient and the surgical team. To limit the risk of infections in operating rooms, it is necessary to have a product capable of fulfilling a certain number of essential functions for the ambient environment of these rooms:
Maximum removal and removal of airborne particles.
Réalisation d'un niveau constant de l'humidité de l'air.Achieving a constant level of air humidity.
Réalisation d'un confort climatique et sonore pour l'équipe chirurgicale.Realization of climatic and sound comfort for the surgical team.
Maintien de la salle en surpression permanente.Maintenance of the room in permanent overpressure.
I1 est courant de trouver sur le marché des produits ayant la fonction de fournir un confort climatique pour une pièce ou une zone en général. Ces produits ne sont pas adaptés à l'application spécifique de la bio décontamination de ltair des salles d'opération. It is common to find on the market products having the function of providing climatic comfort for a room or an area in general. These products are not suitable for the specific application of bio-decontamination of the air in operating rooms.
Le produit selon l'invention permet la réalisation des fonctions essentielles pour la bio décontamination de l'air des salles d'opération.Tout d'abord, le produit se présente sous la forme d'une armoire; cette conception permet de placer le produit à proximité de la salle d'opération et dans un local pas obligatoirement spécialisé. Les avantages de cette présentation sont significatifs: accroissement de la sécurité contre la contamination et diminution des coûts représentés par les réseaux d'air de liaison, Plus courts.The product according to the invention makes it possible to carry out the essential functions for bio-decontamination of the air in operating rooms. First of all, the product is in the form of a cabinet; this design makes it possible to place the product near the operating room and in a room that is not necessarily specialized. The advantages of this presentation are significant: increased safety against contamination and lower costs represented by the shorter air connection networks.
L'armoire est à double corps: un corps technique étanche(l)dans lequel l'air est filtré et traité, et un corps extérieur(2)comportant les organes de commande et de surveillance.Ces deux corps sont indépendants. Cette disposition présente plusieurs avantages en particulier, de créer une barrière complémentaire contre la pénétration des poussières,ltespace inclus entre les deux corps fait office de sas (3), et de limiter la propagation du bruit émis par le fonctionnement du ventilateur(l2),effet de la double peau; de faciliter les opérations de surveillance et d'exploitation sans avoir à ouvrir le circuit d'air technique.The cabinet is double-body: a sealed technical body (l) in which the air is filtered and treated, and an external body (2) comprising the control and monitoring elements. These two bodies are independent. This arrangement has several advantages in particular, of creating a complementary barrier against the penetration of dust, the space included between the two bodies acts as an airlock (3), and of limiting the propagation of the noise emitted by the operation of the fan (12), double skin effect; to facilitate monitoring and operating operations without having to open the technical air circuit.
Le bloc technique(l) comporte à l'intérieur de son volume,successivement dans le sens allant de l'entrée d'air(4) à la sortie d'air(l6): un filtre fin(5) monté étanche et assurant la propreté de l'armoire, un échangeur(6) alimenté en eau glacé et ayant la fonction de refroidir ou déshumidifier l'air, un tamis(7)éliminant l'entraînement des gouttelettes d'eau, un échangeur(8) alimenté en eau chaude et ayant la fonction de chauffer l'air.The technical unit (l) comprises, inside its volume, successively in the direction going from the air inlet (4) to the air outlet (16): a fine filter (5) mounted tight and ensuring the cleanliness of the cabinet, an exchanger (6) supplied with iced water and having the function of cooling or dehumidifying the air, a screen (7) eliminating the entrainment of water droplets, an exchanger (8) supplied with hot water and having the function of heating the air.
Tous les composants cités précédemment sont situés au niveau inférieur du bloc technique(l). Ensuite, au niveau inférieur du même bloc technique(l), on trouve successivement dans le sens de l'air: un dispositif de correction acoustique(9) agissant sur l'énergie sonore développée par le fonctionnement du ventilateur un filtre très fin(10) à très haute efficacité, monté étanche et servant de préfiltrage à la filtration absolue finale, un dispositif de correction acoustique(ll) agissant sur l'énergie sonore développée par le fonctionnement du ventilateur(l2), un ventila teur(l2) actionné par un moteur(l3), la vitesse du ventilateur est variable et agit sur la pression progressive de l'air. All the components mentioned above are located at the lower level of the technical block (l). Then, at the lower level of the same technical unit (l), there is successively in the air direction: an acoustic correction device (9) acting on the sound energy developed by the operation of the fan a very fine filter (10 ) very high efficiency, sealed and used as pre-filtration for final absolute filtration, an acoustic correction device (ll) acting on the sound energy developed by the operation of the fan (l2), a fan (l2) actuated by a motor (l3), the fan speed is variable and acts on the progressive air pressure.
Ensuite et de nouveau situés au niveau supérieur du bloc technique(l) et au refoulement du ventilateur(12), un dispositif de correction acoustique(14) agissant sur l'énergie sonore développée par le fonctionnement du ventilateur(12), une rampe d'humidification(15) à débit de vapeur progressif.Then and again located at the upper level of the technical unit (l) and at the discharge of the fan (12), an acoustic correction device (14) acting on the sound energy developed by the operation of the fan (12), a ramp d humidification (15) with progressive vapor flow.
La destination du produit au milieu médical nécessite d'avoir accès au volume intérieur du bloc technique pour désinfection des parois et des composants; aussi tous ces composants sont accessibles par des portes de qualité hermétique situées en fa çade du bloc technique(l)
A l'extérieur du bloc technique sont placés tous les organes complémentaires nécessaires au bon fonctionnement du produit.The destination of the product in the medical environment requires access to the interior volume of the technical unit for disinfection of the walls and components; also all these components are accessible by hermetic quality doors located in front of the technical unit (l)
Outside the technical block are placed all the additional organs necessary for the proper functioning of the product.
L'architecture de la salle d'opération et les besoins des équipes chirurgicales sont communs à tous les pays. L'unité d'application du produit selon l'invention répond à ces exgences et s'-ouvre à la production industrielle. The architecture of the operating room and the needs of surgical teams are common to all countries. The unit of application of the product according to the invention meets these requirements and opens up to industrial production.
