DISPOSITIF DE DECONTAMINATION DES SIPHONS. DEVICE FOR DECONTAMINATION OF SIPHONS.
La présente invention a pour objet un dispositif de décontamination de siphons.The present invention relates to a device for decontaminating siphons.
Il se rapporte d'une manière générale à la sécurisation des siphons de lavabos, éviers et autres auges à vocation non exclusive des milieux de la santé et repose sur l'utilisation de la lumière dans ses longueurs d'onde biocides au travers d'un appareil en regard de la zone à sécuriser.It generally relates to the securing of siphons for sinks, sinks and other troughs with a non-exclusive vocation of the health sector and is based on the use of light in its biocidal wavelengths through a device next to the area to be secured.
L'eau en établissement de soins est globalement considérée comme critique tant du point de vue de l'utilisation qui va en être faite que du point de vue de son aptitude à être un vecteur support, identifié clairement ou non, de maladies nosocomiales (qui se contractent lors d'une hospitalisation). Le risque pathogène clairement identifié par les instances de la santé publique représente un poids financier important et génère une image de la santé loin de la stratégie d'implantation de système d'assurance de la qualité en milieu hospitalier.Water in healthcare establishments is generally considered to be critical both from the point of view of the use that will be made of it and from the point of view of its ability to be a carrier vector, clearly or not identified, of nosocomial diseases (which contract during hospitalization). The pathogenic risk clearly identified by public health authorities represents a significant financial burden and generates an image of health far from the strategy of implementing a quality assurance system in hospitals.
Les pathologies rencontrées dans le cas de mode d'utilisation de l'eau qui nous intéresse ici, sont consécutives à une contamination de bactéries type Pseudomonas Aeruginosa, conformes fécaux, E. Coli, Streptocoques et Staphylocoques pour les principaux.The pathologies encountered in the case of mode of use of water which interests us here, are consecutive to a contamination of bacteria type Pseudomonas Aeruginosa, faecal conforms, E. Coli, Streptococci and Staphylococci for the main ones.
Le type de contamination qu'il est envisagé de traiter est la rétro contamination du matériel ou des opérateurs via les rebonds de l'eau en lavabo sur la grille ou plaque de bonde de siphon. Il est démontré que lors d'un rebond de goutte, la partie siphon aval représentant une concentration de micro-organismes, appartenant au réseau des eaux usées, permet à ladite goutte par arrachage de capturer un organisme et de le déposer de façon aléatoire alentour, et spécifiquement sur la main. La contamination d'un patient se fait alors au cours de l'acte chirurgical qui s'en suit. Actuellement la prévention de cette rétro-contamination parThe type of contamination that it is envisaged to treat is retro contamination of the equipment or of the operators via the rebounds of the water in the sink on the grid or siphon drain plate. It has been shown that during a drop rebound, the downstream siphon part representing a concentration of microorganisms, belonging to the wastewater network, allows said drop by uprooting to capture an organism and deposit it randomly around, and specifically on the hand. Contamination of a patient then occurs during the surgical procedure that follows. Currently preventing this retro-contamination by
"arrachage mécanique" est organisée autour d'une chimie administrée à l'évacuation du lavabo, et plus généralement à tout point d'eau. Cette procédure ne pouvant assurer une garantie de résultat systématique reste insatisfaisante au regard du risque clairement identifié. Les procédés photoniques ont été étudiés pendant de nombreuses années et des efforts ont été réalisés pour appliquer ce principe physico-chimique à l'épuration ou à la stérilisation de l'eau ou d'autres cibles. Par exemple, le brevet US N° 2 072417 décrit l'irradiation de substances telles que le lait, avec des rayons actifs de type UV, le brevet US N° 3 817 703 décrit la stérilisation d'un matériel au moyen d'une lumière laser puisée et la demande de brevet N° FR 99 02 545 propose un dispositif d'épuration de fluide par impulsions photoniques constitué d'une lampe au xénon de forme hélicoïdale à une ou plusieurs spires émettant un rayonnement allant du bas ultraviolet à l'infrarouge sans discontinuité, et montée sur un tube cylindrique en quartz dans lequel passe le fluide à traiter."mechanical uprooting" is organized around a chemistry administered to the evacuation of the sink, and more generally to any water point. This procedure, which cannot guarantee a systematic result, remains unsatisfactory with regard to the clearly identified risk. Photonic processes have been studied for many years and efforts have been made to apply this physico-chemical principle to the purification or sterilization of water or other targets. For example, US Patent No. 2,074,417 describes the irradiation of substances such as milk, with active UV rays, US Patent No. 3,817,703 describes the sterilization of equipment using a light pulsed laser and patent application N ° FR 99 02 545 proposes a device for purifying fluid by photonic pulses consisting of a xenon lamp of helical shape with one or more turns emitting radiation ranging from low ultraviolet to infrared without discontinuity, and mounted on a cylindrical quartz tube through which the fluid to be treated passes.
Le dispositif selon la présente invention a pour objectif l'application d'une technologie photonique novatrice permettant de garantir la sécurisation des lavabos et éviers par destruction systématique des micro-organismes pouvant séjourner dans le siphon et s'y reproduire, en constituant une zone de confinement entre l'intérieur et l'extérieur (réseau d'eau usée) de l'enceinte aseptique, hyper-aseptique ou autre à vocation d'actes médicaux.The device according to the present invention aims to apply innovative photonic technology to guarantee the security of sinks and sinks by systematic destruction of microorganisms that can stay in the siphon and reproduce there, by constituting a zone of confinement between inside and outside (wastewater network) of the aseptic, hyper-aseptic or other enclosure intended for medical procedures.
Ce dispositif permet non seulement de sécuriser le siphon de façon à éviter un risque nosocomial par éclaboussure, mais également d'aboutir à ce que plus aucune chimie, procédé de prévention actuellement utilisé, ne soit nécessaire à approcher ce principe de sécurisation, et donc à terme de ne générer que des effluents propres au regard de la législation en vigueur et à venir.This device not only makes it possible to secure the siphon so as to avoid a nosocomial risk by splashing, but also to achieve that no more chemistry, currently used prevention process, is necessary to approach this principle of security, and therefore to term to generate only clean effluents with regard to current and future legislation.
Le procédé utilisé étant photonique, il est le seul à pouvoir offrir une réponse à ce problème nosocomial majeur, où à ce jour la seule solution étudiée et appliquée est un remplissage de la tuyauterie d'écoulement par un produit chimique biocide.The process used being photonic, it is the only one able to offer an answer to this major nosocomial problem, where to date the only solution studied and applied is filling the flow piping with a biocidal chemical.
Le dispositif revendiqué est constitué d'une lampe flash disposée en périphérie de la zone à sécuriser entre le siphon et l'évacuation du lavabo et apte à générer des impulsions photoniques contenant 1 à 5% de rayons ultraviolets à partir de 200 nm, couvrant le spectre complet du couplage de l'ADN et de densité énergétique telle que la zone amont au siphon reste totalement exempte de micro-organismes, de façon à empêcher la progression vers le lavabo de micro-organismes sous forme d'une production de bio-film potentiellement pathogène. Sur les dessins schématiques annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention: la figure 1 montre en coupe partielle l'implantation d'un appareil de décontamination sur la tubulure d'écoulement d'un lavabo et la figure 2 est un agrandissement du dispositif de décontamination.The claimed device consists of a flash lamp placed on the periphery of the area to be secured between the siphon and the sink outlet and capable of generating photonic pulses containing 1 to 5% of ultraviolet rays from 200 nm, covering the full spectrum of DNA coupling and energy density such that the upstream area to the siphon remains completely free of microorganisms, so as to prevent the progression to the sink of microorganisms in the form of a biofilm production potentially pathogenic. In the appended schematic drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention: FIG. 1 shows in partial section the installation of a decontamination apparatus on the tubing d flow from a sink and Figure 2 is an enlargement of the decontamination device.
Le dispositif, figures 1 et 2, est constitué d'un boîtier 1 dans lequel sont disposés une lampe 2 au xénon destinée à émettre un rayonnement photonique impulsionnel, et les équipements 3 électriques et électroniques d'alimentation et de contrôle.The device, Figures 1 and 2, consists of a housing 1 in which are arranged a xenon lamp 2 intended to emit pulsed photonic radiation, and the electrical and electronic equipment 3 for power and control.
Ce système constitue un module s'insérant à la sortie de la bonde 4 du lavabo 5, en amont du siphon 6.This system constitutes a module inserted at the outlet of the drain 4 of the sink 5, upstream of the siphon 6.
La lampe flash 2 mise en jeu est disposée en périphérie de la zoneThe flash lamp 2 used is placed on the periphery of the area
7 à sécuriser de manière à créer un éclairement impulsionnel concentrique fournissant à la surface du tube d'évacuation 8 une énergie surfacique au spectre UV biocide optimale et suffisante pour éviter toute reproduction et présence de micro-organismes vivants. La périodicité de répétition des impulsions est telle qu'il est impossible qu'un micro-organisme se reproduise par croissance de bio-film de façon à traverser cette zone entre deux impulsions biocides.7 to be secured so as to create a concentric pulse illumination providing the surface of the evacuation tube 8 with surface energy with an optimal biocidal UV spectrum and sufficient to avoid any reproduction and the presence of living microorganisms. The pulse repetition periodicity is such that it is impossible for a microorganism to reproduce by biofilm growth so as to cross this zone between two biocidal pulses.
La paroi latérale du tube d'évacuation 8 au droit de la lampe 2 est réalisée dans un matériau tel que le quartz laissant passer le spectre lumineux ultraviolet.The side wall of the discharge tube 8 to the right of the lamp 2 is made of a material such as quartz allowing the ultraviolet light spectrum to pass.
La lampe 2 sera de forme torique, de façon à entourer le tube d'évacuation 8. Un réflecteur parabolique 9, ceinturant la lampe 2, permet de concentrer les rayons lumineux sur la zone 7 à sécuriser.The lamp 2 will be toroidal in shape, so as to surround the evacuation tube 8. A parabolic reflector 9, encircling the lamp 2, makes it possible to concentrate the light rays on the area 7 to be secured.
Le dispositif en fonctionnement ne consomme que quelques watts moyen, ce qui permet d'utiliser un bloc d'alimentation 10 peu encombrant, l'ensemble de l'appareil pouvant s'installer sans difficultés sur tous les systèmes d'évacuation existants de lavabos 5 ou d'éviers.The device in operation consumes only a few watts on average, which makes it possible to use a power supply unit 10 that takes up little space, the whole of the device being able to be installed without difficulty on all the existing evacuation systems of sinks 5 or sinks.
Le but n'est pas spécifiquement de traiter le débit d'évacuation, mais plus particulièrement, et sans exclusion de cas, de traiter le tube d'évacuation 8 menant au siphon 6. Il s'agit de générer de façon périodique des séquences de flashes contenant 1 à 5% d'UV à partir de 200 nm d'une densité énergétique suffisante pour empêcher la progression vers le lavabo 5 de micro-organismes sous forme d'une production de bio-film potentiellement pathogène.The aim is not specifically to deal with the evacuation rate, but more particularly, and without excluding any case, to treat the evacuation tube 8 leading to the siphon 6. This involves periodically generating sequences of flashes containing 1 to 5% of UV from 200 nm of a sufficient energy density to prevent the progression to the sink 5 of microorganisms in the form of a potentially pathogenic biofilm production.
Comme il résulte de ce qui précède, l'invention ne se limite pas à la seule forme d'exécution de ce dispositif de décontamination par impulsions photoniques décrite ci-dessus à titre d'exemple; elle en embrasse au contraire toutes les variantes de réalisation et d'application respectant les mêmes principes.As follows from the above, the invention is not limited to the sole embodiment of this photonic pulse decontamination device described above by way of example; on the contrary, it embraces all the variant embodiments and applications respecting the same principles.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
