Description

DISPOSITIF DE DÉCONTAMINATION DES SONDES MÉDICALES ENDOCAVITAIRES DEVICE FOR DECONTAMINATION OF ENDOCAVITY MEDICAL PROBES

La présente invention a pour objet un dispositif de décontamination des sondes et cathéters médicaux endocavitaires.The present invention relates to a device for decontamination of endocavitary medical probes and catheters.

Il est destiné à assurer une désinfection rigoureuse des sondes et cathéters endocavitaires de tous types, et tout particulièrement des sondes urinaires.It is intended to ensure rigorous disinfection of endocavity catheters and catheters of all types, and especially urinary catheters.

La majorité du risque de maladie nosocomiales est représenté par les actes de sondage urinaire. Ce type de contamination provient soit du milieu extrait lui-même soit d'une mise à l'air au niveau et au moment de la connexion de la poche.The majority of the risk of nosocomial disease is represented by urinary catheterization procedures. This type of contamination comes either from the extracted medium itself or from an air vent at the level and at the time of connection of the bag.

Ce risque pathogène clairement identifié par les instances de la santé publique représente un poids financier colossal et génère une image de la santé loin de la stratégie d'implantation de système d'assurance de la qualité en milieu hospitalier. Les pathologies rencontrées, principalement infection urinaire, sont consécutives à une contamination de bactéries type candidae albicans et echiriechia coli. La contamination d'un patient se fait soit au moment de l'introduction de la sonde, soit par rupture de l'intégrité du positionnement de la sonde dans l'urètre, soit par rétro contamination de la sonde par la poche de rétention de l'urine.This pathogenic risk clearly identified by public health authorities represents a colossal financial burden and generates an image of health far from the strategy of implementing a quality assurance system in hospitals. The pathologies encountered, mainly urinary tract infection, are consecutive to contamination of bacteria such as candidae albicans and echiriechia coli. The contamination of a patient is done either at the time of the introduction of the probe, or by rupture of the integrity of the positioning of the probe in the urethra, or by retro contamination of the probe by the retention pocket of the 'urine.

Actuellement, dans le domaine du sondage urinaire invasif, deux alternatives s'offrent comme solutions potentielles : sonder le moins possible le patient car la maîtrise stricte de l'acte n'est pas garantie (facteur humain), ou prévoir que les recherches menées sur les sondes biocides donneront satisfaction.Currently, in the field of invasive urinary catheterization, two alternatives are available as potential solutions: probe the patient as little as possible because strict control of the act is not guaranteed (human factor), or provide that research conducted on biocidal probes will give satisfaction.

Le dispositif selon la présente invention a pour objectif de remédier à cet état de choses. Il permet en effet de garantir la non-prolifération d'un micro-organisme pathogène par rétro contamination à l'intérieure d'une sonde urinaire ou autre sonde invasive d'extraction, de la poche de rétention vers le patient.The device according to the present invention aims to remedy this state of affairs. It in fact makes it possible to guarantee the non-proliferation of a pathogenic microorganism by retro contamination inside a urinary probe or other invasive probe for extraction, from the retention pocket towards the patient.

Le système de décontamination, adaptable à tout type de sonde ou cathéter, peut être mis en place de façon permanente, quelle que soit la durée de sondage. Il permet en outre la mobilité des personnes sondées. Le système repose sur l'utilisation de la lumière dans ses longueurs d'ondes biocides au travers d'un matériau, de façon à utiliser cette faible portion d'énergie surfacique transmise à la périphérie interne de la sonde à décontaminer pour générer une zone de sécurisation. Il est constitué d'une alimentation électrique générant les impulsions de courant, d'une liaison électrique vers la lampe et d'une enceinte de section elliptique formant pince et contenant la lampe placée à l'un des foyers de l'ellipse, cette pince venant entourer la sonde ou le cathéter situé à l'autre foyer en un lieu de sa longueur conforme à son utilisation.The decontamination system, adaptable to any type of probe or catheter, can be installed permanently, whatever the duration of the probe. It also allows the mobility of respondents. The system relies on the use of light in its biocidal wavelengths through a material, so as to use this small portion of surface energy transmitted to the internal periphery of the probe to be decontaminated to generate a zone of security. It consists of an electrical power supply generating current pulses, an electrical connection to the lamp and an elliptical section enclosure forming a clamp and containing the lamp placed at one of the focal points of the ellipse, this clamp from surrounding the probe or catheter located at the other focal point in a place of its length in accordance with its use.

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 représente en perspective axonométrique, le dispositif de décontamination raccordé à son boîtier d'alimentation et monté sur une sonde urinaire, la figure 2 est une coupe transversale suivant les flèches F1 de la figure 1 montrant le dispositif en position fermée et la figure 3 représente dans les mêmes conditions le dispositif en position ouverte.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 axonometric perspective, the decontamination device connected to its supply unit and mounted on a urinary catheter, Figure 2 is a cross section along the arrows F1 of Figure 1 showing the device in the closed position and Figure 3 shows under the same conditions the device in the open position.

Le dispositif, figures 1 à 3, est constitué d'une enceinte 1 formée d'une portion de tube de section elliptique fermée à ses deux extrémités par des parois latérales 2 planes.The device, FIGS. 1 to 3, consists of an enclosure 1 formed by a portion of tube of elliptical section closed at its two ends by side walls 2 that are flat.

A l'un des foyers de l'ellipse, à l'intérieur de l'enceinte 1 , est disposée une lampe 3 de type "flash" et, à l'autre foyer, se trouve un manchon 4 transparent traversant l'enceinte entre les deux parois latérales 2 et déterminé pour permettre le passage de la sonde 5 ou du cathéter à décontaminer.At one of the focal points of the ellipse, inside the enclosure 1, a lamp 3 of the "flash" type is arranged and, at the other focus, is a transparent sleeve 4 passing through the enclosure between the two side walls 2 and determined to allow the passage of the probe 5 or of the catheter to be decontaminated.

L'enceinte 1 est formée de deux parties 6, 7 pivotant autour d'une articulation 8 de façon à constituer une pince pouvant s'ouvrir au droit du manchon 4, formé lui-même de deux portions semi-cylindriques 4', 4", pour insérer la sonde 5. La face interne 9 de la paroi tubulaire est réfléchissante, et sa forme elliptique assure un éclairement uniforme sur l'enveloppe de la sonde 5.The enclosure 1 is formed by two parts 6, 7 pivoting around a hinge 8 so as to constitute a clamp which can open at right angles to the sleeve 4, itself formed by two semi-cylindrical portions 4 ′, 4 " , to insert the probe 5. The internal face 9 of the tubular wall is reflective, and its elliptical shape ensures uniform illumination on the envelope of the probe 5.

La lampe 3 est reliée par un câble souple 10 multiconducteurs à un boîtier 11 portable d'alimentation et de contrôle assurant la mise en forme des impulsions lumineuses.The lamp 3 is connected by a flexible multiconductor cable 10 to a portable power and control box 11 ensuring the shaping of the light pulses.

La base de technologie photonique employée est agencée pour générer des flashes de faible durée contenant 5 à 20 % de rayons ultraviolets (UV) à partir de 200 nm, de densité d'énergie suffisamment élevée pour traverser l'épaisseur de la matière (plastique, silicone, etc) de l'enveloppe de la sonde 5 et d'apporter à sa surface interne l'énergie biocide requise pour générer une zone désinfectée, empêchant la prolifération micro biologique vers le patient. La longueur de cette zone est déterminée par plusieurs facteurs, telles que: la plus grande vitesse de prolifération de l'ensemble des cibles micro biologiques visée, la longueur (et donc le poids) de la pince contenant la lampe 3, la fréquence de répétition des flashes garantissant le non franchissement de la zone désinfectée entre deux intervalles.The basic photonic technology used is designed to generate short-term flashes containing 5 to 20% of ultraviolet (UV) rays from 200 nm, with an energy density high enough to pass through the thickness of the material (plastic, silicone, etc) of the envelope of the probe 5 and of bringing to its internal surface the biocidal energy required to generate a disinfected area, preventing micro-biological proliferation towards the patient. The length of this zone is determined by several factors, such as: the highest rate of proliferation of all the targeted micro biological targets, the length (and therefore the weight) of the forceps containing the lamp 3, the repetition frequency flashes guaranteeing that the disinfected area is not crossed between two intervals.

Les caractéristiques du dispositif selon l'invention présentent de nombreux avantages :The characteristics of the device according to the invention have numerous advantages:

- La génération d'impulsion brèves permet de ne pas générer d'échauffement de la sonde ou du cathéter.- The generation of short pulses does not generate overheating of the probe or catheter.

- Le fait que l'enceinte 1 est amovible permet de la dissocier de la sonde 5 qui peut être jetable. - Le procédé étant photonique il est le seul à pouvoir offrir une réponse fiable et offrant une sécurité importante au problème nosocomiale majeur représenté par les sondes urinaires, la seule solution pour combattre ce vecteur d'infection étant à ce jour une imprégnation de la sonde par un produit chimique biocide.- The fact that the enclosure 1 is removable makes it possible to dissociate it from the probe 5 which can be disposable. - The process being photonic it is the only one able to offer a reliable answer and offering an important security to the major nosocomial problem represented by the urinary probes, the only solution to fight this vector of infection being to date an impregnation of the probe by a biocidal chemical.

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.
