Abstract
Description
Lichtgenerator für medizinische Zwecke" Light generator for medical purposes "
Die Erfindung betrifft einen Lichtgenerator für medizinische Zwecke mit mindestens drei Lichtquellen.The invention relates to a light generator for medical purposes with at least three light sources.
Aus der deutschen Patentanmeldung P 30 23 266 ist ein Wundhaken für chirurgische Zwecke aus lichtleitendem Material bekannt. An diesem Wundhaken wird ein Lichtleiter und dieser wiederum an einem Lichtgenerator befestigt. Die bekannten Lichtgeneratoren weisen lediglich eine Lichtquelle auf, sodaß bei einem Ausfall unter Umständen eine Unterbrechung der Operation notwendig ist.From the German patent application P 30 23 266 is a retractor for known surgical purposes from light-conducting material. This retractor is a light guide and this in turn attached to a light generator. The known Light generators only have one light source, so that in the event of a failure an interruption of the operation may be necessary.
Aufgabe der Erfindung ist es, einen Lichtgenerator zu schaffen, der einfach und sicher im Hotrieb ist und mehrere ichkeiten zum @inschalten der @@chtquellen aufweist Gelöst wird die Aufgabe für einen Lichtgenerator der eingangs charakterisierten Art erfindungsgemäß durch eine elektrische Verriegelung derart, daß immer nur zwei der Lichtquellen gleichzeitig einschaltbar sind. Zweckmäßigerweise weist der Lichtgenerater drei lichtquellen auf. Die elektrische Verriegelung weist zweckmäßigerweise einen einpoligen Umschalter, einen einpoligen Einschalter und einen zweipoligen Umschalter auf, wobei der Stromkreis, der die erste Lichtquelle enthält, die Sekundärseite eines ersten Transformators und den ersten Kontakt des einpoligen Umschalters umfasst, der Stromkreis, der die zweite Lichtquelle enthält, entweder aus der Sekundärseite eines zweiten Transformators, der mit dem ersten Transformator primärseitig parallel geschaltet ist, den Kontakt des einpoligen Einschalters, den zweiten Kontakt des zweiten Pols und den zweiten Kontakt des ersten Pols des zweipoligen Umschalters oder den Kontakt des einpoligen Einschalters, den ersten Kontakt des zweiten Pols des zweipoligen Umschalters, den zweiten Kontakt des einpoligen Umschalters und die Sekundärseite des ersten Transformators umfasst, und der Stromkreis, der die dritte Lichtquelle enthält, den ersten Kontakt des ersten Pols des zweipoligen Umschalters und die Sekundärseite des zweiten Transformators umfasst.The object of the invention is to create a light generator that is easy and safe to operate and has several options for switching on the sources The problem is solved for a light generator as characterized at the outset Art according to the invention by an electrical lock such that only two the light sources can be switched on at the same time. The light generator expediently has three light sources on. The electrical lock expediently has a unipolar Changeover switch, a single-pole switch and a two-pole changeover switch, where the circuit containing the first light source, the secondary of a first Transformer and the first contact of the single pole changeover switch, the circuit, which contains the second light source, either from the secondary side of a second Transformer connected in parallel with the first transformer on the primary side is the contact of the single pole switch, the second contact of the second pole and the second contact of the first pole of the two-pole changeover switch or the contact of the single-pole closing switch, the first contact of the second pole of the two-pole Changeover switch, the second contact of the single-pole changeover switch and the secondary side of the first transformer, and the circuit that includes the third light source contains, the first contact of the first pole of the two-pole changeover switch and the Includes secondary side of the second transformer.
Die Vorteile des erfindungsgemäß ausgebildeten Lichtgenerators liegen darin, daß bei zwei fest eingebauten Betriebslichtquellen und einer Reservelichtquelle zwar die Benutzung von jeder beliebigen Lichtquelle möglich ist, wobei aber immer nur zwei Lichtquellen gleichzeitig betrieben werden können und dadurch eine Überlastung des Lichtgenerators verhindert wird.The advantages of the light generator designed according to the invention lie in that with two permanently installed operating light sources and a reserve light source the use of any light source is possible, but always only two light sources can be operated at the same time and thus overload of the light generator is prevented.
Die erfindungsgemäße Schaltung ist in der Zeichnung dargest;ellt.The circuit according to the invention is shown in the drawing.
Mit dem Netzschalter 1 wird eine Kontrollampe 2 und ein Lüfter 3 eingeschaltel. Über den Dz mine 4 kann die Eingangsspannung für die parallelgeschalteten Transformatoren 5a und 5b geregelt werden. AuF der Sekundärseite der Transformatoren 5a und 5b sind drei Lichtquellen 6a, 6b und 6c, wie beispielsweise Halogen-Reflektor-Lampen, angeordnet, die über die Schalter 7a, 7b oder 7c eingeschaltet werden können. Die Schalter 7a, 7b und 7c sind Mikroschalter, die durch die jeweils an dem Generator angeschlossenen Lichtleiter betätigt werden. Die Schalter sind so gewählt und so angeschlossen, daß immer nur zwei Lichtquellen gleichzeitig einschaltbar sind.A control lamp 2 and a fan 3 are switched on with the mains switch 1. Via Dz mine 4, the Input voltage for the parallel-connected Transformers 5a and 5b are regulated. On the secondary side of the transformers 5a and 5b are three light sources 6a, 6b and 6c, such as halogen reflector lamps, arranged, which can be switched on via the switch 7a, 7b or 7c. the Switches 7a, 7b and 7c are microswitches that are operated by the respectively on the generator connected fiber optics are operated. The switches are chosen like that and like that connected so that only two light sources can be switched on at the same time.
