Description
La présente invention concerne une enceinte de désinfection pourThe present invention relates to a disinfection chamber for
instruments médicaux. Plus particulièrement, l'invention se rapporte à une telle enceinte qui comporte par exemple des moyens de suspension d'un ou de plusieurs ins- truments dans cette enceinte entre des moyens de génération d'un rayonnement de désinfection. On a déjà décrit une enceinte de ce type dans le document EP-A-O 839 537. Cette enceinte est délimitée par un fond, au moins une paroi latérale et un couvercle supérieur, chaque instrument comportant une partie active et une partie de raccordement sous forme d'un câble. Cette enceinte comporte également une potence s'étendant à l'intérieur et en partie supérieure de l'enceinte, parallèlement au fond et en surplomb du fond, cette potence comportant une pluralité d'organes de suspension, chacun d'eux étant desti- né à coopérer avec une partie du câble voisine de la partie active de l'instrument pour maintenir en suspension l'instrument dans l'enceinte. Selon un mode de réalisation décrit dans ce document, l'enceinte est associée à des moyens de génération d'un rayonnement de désinfection d'UV de type C par exemple. Ces moyens de génération sont par exemple formés par un ou plusieurs tubes logés dans des décrochements correspondants de l'enceinte. Mais ces structures présentent un certain nombre d'inconvénients, notamment au niveau de l'optimisation de la réflexion du rayonnement et donc de la désinfection des instruments. medical instruments. More particularly, the invention relates to such a chamber which comprises for example means for suspending one or more instruments in this chamber between means for generating a disinfection radiation. An enclosure of this type has already been described in document EP-A-0 839 537. This enclosure is delimited by a bottom, at least one side wall and an upper cover, each instrument comprising an active part and a connection part in the form of a base. 'a cable. This enclosure also comprises a bracket extending inside and in the upper part of the enclosure, parallel to the bottom and overhanging the bottom, this bracket comprising a plurality of suspension members, each of them being intended to cooperate with a portion of the cable adjacent to the active part of the instrument to hold the instrument in suspension in the enclosure. According to an embodiment described in this document, the enclosure is associated with means for generating a type C UV disinfection radiation, for example. These generation means are for example formed by one or more tubes housed in corresponding recesses of the enclosure. But these structures have a number of disadvantages, particularly in terms of optimizing the reflection of the radiation and therefore the disinfection of the instruments.
Le but de l'invention est donc de résoudre ces problèmes. A cet effet l'invention a pour objet une enceinte de désinfection pour instruments médicaux, du type comportant des moyens de génération d'un rayonnement de désinfection, caractérisée en ce que le rayonnement de désinfection est concentré autour d'une longueur d'onde d'environ 253,8 nm et en ce que la surface intérieure de l'enceinte est revêtue au moins en partie par du matériau spéculaire. Selon des modes particuliers de réalisation, l'enceinte selon l'invention comporte une ou plusieurs des caractéristiques suivantes : - l'enceinte présente une surface intérieure de section circulaire ; - la surface intérieure de l'enceinte présente des décrochements semi-circulaires de réception des moyens de génération du rayonnement ; - les moyens de génération du rayonnement comportent quatre tubes disposés à 90 les uns des autres dans l'enceinte ; - le matériau spéculaire est formé par de l'aluminium grand brillant ; et - le matériau spéculaire est formé par de l'inox poli. L'invention sera mieux comprise à l'aide de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant au dessin annexé qui représente une vue de dessus en coupe d'une portion d'enceinte selon l'invention. On a en effet illustré sur cette figure une portion d'une enceinte de désinfection pour instruments médicaux. Cette portion d'enceinte est désignée par la référence générale 1 sur cette figure et est donc adaptée pour recevoir un instrument médical à désinfecter, cet instrument étant désigné par la référence générale 2 sur cette figure et se présentant par exemple sous la forme d'une sonde ou autre. L'enceinte présente une surface intérieure de section circulaire par exemple. The object of the invention is therefore to solve these problems. For this purpose, the subject of the invention is a disinfection enclosure for medical instruments, of the type comprising means for generating disinfection radiation, characterized in that the disinfection radiation is concentrated around a wavelength of about 253.8 nm and in that the inner surface of the enclosure is at least partially coated with specular material. According to particular embodiments, the enclosure according to the invention comprises one or more of the following characteristics: the enclosure has an inner surface of circular section; the inner surface of the enclosure has semicircular recesses for receiving the means for generating the radiation; - The radiation generation means comprise four tubes arranged at 90 from each other in the enclosure; the specular material is formed by high gloss aluminum; and the specular material is formed of polished stainless steel. The invention will be better understood from the following description given solely by way of example and with reference to the appended drawing which shows a sectional top view of an enclosure portion according to the invention. . This figure has in fact illustrated a portion of a disinfection chamber for medical instruments. This portion of enclosure is designated by the general reference 1 in this figure and is therefore adapted to receive a medical instrument to be disinfected, this instrument being designated by the general reference 2 in this figure and being for example in the form of a probe or other. The enclosure has an inner surface of circular section for example.
Cette surface est désignée par la référence générale 3 sur cette figure et permet alors d'optimiser la réflexion du rayonnement engendré par les moyens de génération du rayonnement sur l'instrument à désinfecter. Le rayonnement est concentré autour d'une longueur d'onde d'environ 253,8 nm, pour des raisons de réduction des effets thermiques sur les instruments. This surface is designated by the general reference 3 in this figure and then optimizes the reflection of the radiation generated by the radiation generating means on the instrument to be disinfected. The radiation is concentrated around a wavelength of about 253.8 nm, for reasons of reducing the thermal effects on the instruments.
Dans l'exemple de réalisation illustré sur cette figure, ces moyens de génération cornprennent en fait quatre tubes désignés respectivement par les références générales 4, 5, 6 et 7, répartis à 90 les uns des autres dans des décrochements semi-circulaires de réception correspondants ménagés dans cette surface intérieure de l'enceinte. In the exemplary embodiment illustrated in this figure, these generating means in fact comprise four tubes designated respectively by the general references 4, 5, 6 and 7, distributed at 90 from each other in corresponding semicircular receiving recesses. formed in this inner surface of the enclosure.
Ces décrochements semi-circulaires sont désignés respectivement par les références 8, 9, 10 et 11 sur cette figure. II va de soi bien entendu qu'un nombre différent de tubes et une dis-position autre de ceux-ci peuvent également être envisagés. These semi-circular recesses are designated respectively by references 8, 9, 10 and 11 in this figure. It goes without saying of course that a different number of tubes and a dis-position other of these may also be considered.
De plus, l'enceinte peut également être optimisée si la surface intérieure 3 est revêtue au moins en partie et de préférence en totalité par du matériau spéculaire tel que, par exemple, de l'aluminium grand brillant, de l'inox poli, ...etc. En effet, il a été constaté que l'utilisation d'un tel matériau de revêtement de la surface permettait également d'optimiser encore la ré-flexion du rayonnement et donc la qualité de la désinfection. On conçoit alors qu'une telle structure et l'utilisation d'une telle sur-face intérieure pour l'enceinte permettent d'optimiser la réflexion des rayonnements émis par les moyens de génération de ce rayonnement afin d'opti- miser la désinfection de l'instrument. De plus, la concentration du rayonnement autour de la longueur d'onde indiquée de 253,8 nm permet également de réduire son impact thermique sur les instruments médicaux. En effet, ceux-ci peuvent, par exemple, comporter des sondes thermosensibles qu'il convient donc de ménager afin d'éviter toute dégradation. In addition, the enclosure can also be optimized if the inner surface 3 is coated at least in part and preferably entirely by specular material such as, for example, high gloss aluminum, polished stainless steel. ..etc. Indeed, it has been found that the use of such a coating material on the surface also makes it possible to further optimize the reflection of the radiation and therefore the quality of the disinfection. It is then conceivable that such a structure and the use of such an inner surface for the enclosure make it possible to optimize the reflection of the radiation emitted by the means for generating this radiation in order to optimize the disinfection of the instrument. In addition, the concentration of radiation around the indicated wavelength of 253.8 nm also reduces its thermal impact on medical instruments. Indeed, they may, for example, include heat-sensitive probes that should be managed to avoid any degradation.
