Description
Gerät zur sterilisierenden, bakteriziden Bestrahlung von Objekten Die Erfindung betrifft ein Gerät zur sterilisierenden, bakteriziden Bestrahlung von Objekten der Medizinaltechnik, insbesondere der Dentaltechnik.Device for sterilizing, bactericidal irradiation of objects the The invention relates to a device for sterilizing, bactericidal irradiation of Objects of medical technology, especially dental technology.
Zur Sterilisation von Gegenständen der ärztlichen Praxis, insbesondere von zahnärztlichen Präparaten (Alginatabirücke, Prothesen u.dgl0), die nicht den hohen Temperaturen eines Heißluftsterilisators oder des Äutoklavs ausgesetzt werden dürfen, hat man bereits eine UV-Bestrahlung eingesetzt, die auch bei Raumtemperatur wirksam ist. Ein entsprechendes Gerät besteht aus einem kastenförmigen Behälter mit einer Bedienungsklappe, innerhalb dessen ein oder mehrere UV-Stranler, beispielsweise tueckæilberdampf-Entladungsröhren angeordnet sind.For the sterilization of medical practice items, in particular of dental preparations (alginate bridges, prostheses, etc.) that do not exposed to high temperatures of a hot air sterilizer or the autoclave UV radiation has already been used, even at room temperature is effective. A corresponding device consists of a box-shaped container with a control flap, within which one or more UV Stranler, for example tueckæilberdampf-discharge tubes are arranged.
Der Erfindung liegt die Aufgabe zu Grunde, die Bestrshlungsin tensität innerhalb eines derartigen Gerätes zu steigern, ohne deshalb die Anschlußleistung des Gerätes erhöhen zu müssen.The invention is based on the object, the radiation intensity to increase within such a device, without therefore the connection power of the device to have to increase.
Erfindungsgemäß wird dies dadurch erreicht, daß jeder UV-Strahler auf seiner dem zu bestrahlenden Objekt abgewandten Seite von einem spärich gekrümmten apiegel umgeben ist, in dessen Brennpunkt er sich befindet und der die auf ihn fallende U7-Strahlung parallel reflektiert.According to the invention this is achieved in that each UV radiator on its side facing away from the object to be irradiated by a sparsely curved one apiegel is surrounded, in whose focal point it is and the one falling on it U7 radiation reflected in parallel.
Eine im Rahmen der Erfindung liegende besonders günstige Ausführungsform eines derartigen Gerätes wird in der Weise ausgebildet, daß jeder W-Strahler im Brennpunkt eines Paraboloidspiegels angeordnet ist.A particularly favorable embodiment within the scope of the invention such a device is designed in such a way that each UV radiator in the Focal point of a parabolic mirror is arranged.
Um die Intensität der W-Bestrahlung der Objekte zu steigern, besteht der Objekttrager nach einem weiteren Brfindungsgedanken aus UV-strahlungsdurchlässigem Material, beispielsweise Quarz und es sind oberhalb sowie unterhalb dieses Objektträgers ein oder mehrere UV-Strahler angeordnet. Der Objektträger läßt die UV-Strahlen ungehindert passieren und auf die jeweiligen Objekte treffen, so daß auch von der Uaterveito her eine intensive sterilisierende Wirkung ersielt wird.In order to increase the intensity of the UV irradiation of the objects, there is the slide according to a further idea of the invention made of UV radiation permeable Material, for example quartz, and there are above and below this slide one or more UV lamps arranged. The slide leaves the UV rays unhindered pass and hit the respective objects, so that also from the Uaterveito an intensive sterilizing effect is achieved.
Durch die 3iifldelung und Außrichtung der W-Strahlen, die durch die parallel reflektierenden Spiegel erzielt wird, tritt eine wesentliche Intensivierung der Bestrahlungswirkung ein, so daß jetzt die Sterilisation in kürzerer Zeit als bisher durchgeführt werden kann.Because of the diffusion and alignment of the UV rays passing through the parallel reflecting mirror is achieved, a substantial intensification occurs the radiation effect, so that now the sterilization in less time than can be carried out so far.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt, an Hand dessen diese im Folgenden näher erläutert wird.An exemplary embodiment of the invention is shown schematically in the drawing shown, on the basis of which this is explained in more detail below.
Danach ist innerhalb des Gehäuses 1 der aus mehreren Q;arzstäben 2 bestehende Objektträger gelagert. Oberhalb und unterhalb dieses Objektträgers sind die UV-Strahler 3 bis 6 angeordnet, denen jeweils die Paraboloidspiegel 7 bis 10 zugeordnet sind.Thereafter, inside the housing 1 is the one made up of several medical rods 2 existing slides stored. Above and below this slide are the UV lamps 3 to 6 are arranged, each of which has the paraboloid mirror 7 to 10 assigned.
Die von den W-Strahlern ausgehende Strahlung wird so praktisch verlustfrei auf den Objektträger konzentriert.The radiation emanating from the UV radiators is practically loss-free focused on the slide.
