Abstract

By using intense flash light, faster and more reliable curing of photocuring otoplastic ear casts is achieved. The irradiation here is expediently carried out from below. The irradiation duration and the curing can be improved by about 50%.

Description

Die bisher in der Otoplastik zur Lichthärtung verwendeten Geräte basieren alle auf Leuchtstoffröhren als Lichtquellen. Diese haben jedoch den Nachteil, daß sie eine relativ geringe Leuchtdichte aufweisen. Dies ist insbesondere für flexible Ohrpaßstücke nachteilig, weil durch die geringe Leuchtdichte der Leuchtstoffröhren nur eine geringe und ungenügende Reißfestig­ keit der flexiblen otoplastischen Ohrabdruckstücke erreicht wird. Dadurch ist es wünschenswert, ein Verfahren bzw. ein Gerät zu entwickeln, das im ausreichenden Maße genügend Lichtenergie für die Photopolymerisation von otoplastischen Kunststoffen zur Verfügung stellt.The previously used in the otoplastic for light curing Devices are all based on fluorescent tubes as light sources. However, these have the disadvantage that they are relatively small Have luminance. This is especially for flexible Adverse earpieces disadvantageous because of the low luminance the fluorescent tubes only a low and insufficient tear resistance of flexible otoplastic ear impression pieces becomes. This makes it desirable to have a method or a Develop device that is sufficient to a sufficient extent Light energy for the photopolymerization of otoplastic Provides plastics.

Erfindungsgemäß wurde die Aufgabe gelöst, indem als Lichtquellen geeignete Blitzlampen verwendet werden. Obwohl die Blitzlampen keine Dauerlichtquellen sind und nur einige Blitze pro Sekunde zur Verfügung stellen können, hat sich gezeigt, daß überraschender Weise die Photopolymerisation durch Lichtblitze eine wesentlich höhere Durchhärtung und Reißfestigkeit bei otoplastischen Kunststoffen ergibt.According to the invention, the object was achieved by using light sources suitable flash lamps are used. Although the flash lamps are not permanent light sources and only a few flashes per second can provide, has been shown to be more surprising Way the photopolymerization by flashes of light an essential higher hardening and tear resistance in otoplastic Plastics results.

Eine besonders vorteilhafte erfindungsgemäße Ausführung ist in Fig. 1) bzw. Fig. 2) dargestellt. Als Lichtquellen werden zwei stabförmige Blitzlampen mit einer aktiven Länge von ca. 10-12 cm benutzt. Diese Blitzlampen werden mit einer Frequenz von 5-50 Hz, vorzugsweise 10-12 Hz betrieben. Die in den beiden Blitzlampen abgeblitzte Leistung beträgt 20-400 W, vorzugsweise ca. 200 W. Die Blitzlampen werden bei einer konstanten Spannung am Abblitzkondensator betrieben. Außerdem ist es vorteilhaft, die Blitzlampen beim Phasennull­ durchgang der Netzspannung zu zünden. A particularly advantageous embodiment according to the invention is shown in Fig. 1) or Fig. 2). Two rod-shaped flash lamps with an active length of approx. 10-12 cm are used as light sources. These flash lamps are operated at a frequency of 5-50 Hz, preferably 10-12 Hz. The power flashed off in the two flash lamps is 20-400 W, preferably approx. 200 W. The flash lamps are operated at a constant voltage on the flash capacitor. It is also advantageous to ignite the flash lamps when the mains voltage crosses zero.

Die Blitzlampen (1) werden so angeordnet, daß sie sich unmittel­ bar unterhalb der Abdruckformen (5), in denen der lichthärtende Kunststoff eingebracht ist, befinden. Die Blitzlampen sind nach unten hin von einem Reflektor (2) umgeben. Nach oben hin sind die Blitzlampen durch eine hochtransparente Glasplatte (6) abgedeckt. Die Abdruckformen (5) befinden sich auf einer zweiten Glasplatte (7), die einige Millimeter oberhalb der unteren Glasplatte (6) liegt. Dazwischen ergibt sich ein Luftspalt von ca. 5 mm. Dadurch wird verhindert, daß heiße Luft von den Blitzlampen hochsteigt und die Auflageplatte der Abdruckformen zu stark erhitzt. Vorteilhaft ist weiterhin, Luft in Längsrichtung parallel zu den Achsen der Blitzlampen sowohl um die Blitzlampen als auch um die Abdruckformen und insbesondere durch den Zwischenraum zwischen den beiden Glasplatten zu blasen.The flash lamps ( 1 ) are arranged so that they are located immediately below the impression molds ( 5 ) in which the light-curing plastic is introduced. The flash lamps are surrounded at the bottom by a reflector ( 2 ). The flash lamps are covered at the top by a highly transparent glass plate ( 6 ). The impression molds ( 5 ) are located on a second glass plate ( 7 ), which is a few millimeters above the lower glass plate ( 6 ). There is an air gap of approx. 5 mm in between. This prevents hot air from rising from the flash lamps and overheating the platen of the impression molds. It is also advantageous to blow air in the longitudinal direction parallel to the axes of the flash lamps both around the flash lamps and around the impression molds and in particular through the space between the two glass plates.

Vorteilhafterweise ist auch der Raum überhalb den Abdruckformen durch Reflektoren (3, 4) abgegrenzt.The space above the impression molds is also advantageously delimited by reflectors ( 3 , 4 ).

Die in Fig. 2) mit (8) bezeichneten Elemente dienen der Lüftung bzw. der Versorgung der Blitzlampen.The elements designated ( 8 ) in FIG. 2 serve for ventilation or the supply of the flash lamps.
