Description
lnit Elektroden versehene Vakuumröhre. ,Die Erfindung betrifft eine mit Elektroden versehene Vakuumröhre.Vacuum tube provided with electrodes. , The invention relates to a vacuum tube provided with electrodes.
Die Erfindung besteht darin, daß die Elektroden unmittelbar von radioaktiver Substanz umgeben sind. Die Vakuumröhre ist zweckmäßig mit einem pulverförmigen Erz angefüllt, das radioaktive Eigenschaften hat.The invention consists in that the electrodes are directly radioactive Substance are surrounded. The vacuum tube is convenient with a powdered ore filled, which has radioactive properties.
Abb. i und 2 sind abgebrochene Schnitte und Ansichten von zwei verschiedenen Ausführungsformen der Röhre.Figs. I and 2 are broken sections and views of two different ones Embodiments of the tube.
In den Enden des zylindrischen Rohres a (Abb. i) sind elektrische Pole, eine Anöde b und eine Kathode c, befestigt, an die Leitungsdrähte d bzw. e angeschlossen sind. Die Pole bestehen aus Platin, Aluminium o. dgl. Das Rohr a ist mit pulverförmigem Erz f gefüllt, das radioaktive Substanzen, wie Radium, Thorium, Uran, Pechblende o. dgl. und Phosphor, enthält.In the ends of the cylindrical tube a (Fig. I), electrical poles, an anode b and a cathode c, are attached, to which lead wires d and e, respectively, are connected. The poles consist of platinum, aluminum or the like. The tube a is filled with powdered ore f which contains radioactive substances such as radium, thorium, uranium, pitchblende or the like and phosphorus.
Die in Abb. i gezeigte Röhre wird an den Enden ergriffen und über den zu behandelnden Körperteil geführt, und zwar in jenen Fällen, in denen die Lage der Krankheitskeime nicht genau festgestellt ist, die in Abb.2 gezeigte Vakuumröhre dagegen dann, wenn die Lage der Krankheitskeime bekannt ist.The tube shown in Fig. I is gripped at the ends and over guided the body part to be treated, in those cases in which the situation the germs are not exactly identified, the vacuum tube shown in Fig.2 on the other hand, if the location of the germs is known.
Die letztgenannte Röhre hat einen Glashandgriff g2, dessen eines Ende g3 als Rohr ausgebildet und mit der Vakuumbirne g4 verbunden ist, wobei ein Drahtnetz g3 die Birne von dem Rohr g3 trennt. Das obere Ende der Birne ist vorzugsweise kegelig, wie bei ge gezeigt, während das gegenüberliegende Ende g7 gerade ist und im rechten Winkel zu den Seitenwänden liegt. Die Birne ist mit pulverförmigen radioaktiven Erzen gefüllt oder mit einem Erz, das radioaktive Substanzen g$ enthält. In dem kegeligen Ende der Birne g4 ist ein elektrischer Pol g9 angeordnet, dessen äußeres Ende mit einem Leitungsdraht h verbunden ist. Wird elektrischer Strom von hoher Periodenzahl durch den Draht geschickt, so wird das Erz g8 erhitzt und in einen leuchtenden fluorizierenden Zustand versetzt, in welchem es Strahlen aussendet. Beim Gebrauch wird das Ende g7 der Birne g4 unmittelbar oder in einem kleinem Abstand über die zu behandelnde Stelle geführt.The latter tube has a glass handle g2, one end of which g3 is designed as a tube and is connected to the vacuum bulb g4, with a wire mesh g3 separates the bulb from the tube g3. The top of the pear is preferably conical, as shown at ge, while the opposite end g7 is straight and in the right Angle to the side walls. The pear is powdered with radioactive Ores filled with ore containing radioactive substances. By doing tapered end of the bulb g4 is an electrical pole g9, the outer End is connected to a lead wire h. Will electric current of high Period number sent through the wire, the ore is heated g8 and put into a in a luminous, fluorescent state in which it emits rays. In use, the end g7 of the pear g4 becomes immediately or at a small distance guided over the area to be treated.
