Description

Verfahren zur Herstellung radioaktiver plastischer lassen beliebiger Form. Seitdem man erkannt hat, daß die praktisch erreichbare Menge von Emanation weit unter ihrer Schädigungsgrenze liegt, hat die Anwendung radioaktiver Körper in der Heilkunde in Form von Kompressen u. dgl. einen bedeutenden Aufschwung genommen.Process for the production of radioactive plastic leave any Shape. Since then it has been realized that the practically achievable amount of emanation is far below its damage limit, the application of radioactive bodies has in medicine in the form of compresses and the like.

Die in den Handel gekommenen Kompressen sind mit radioaktiven Substanzen gefüllte Säckchen aus Stoff, die ihrerseits nochmals in einer Stoffumhüllung stecken. Sie sind in ihrer Anwendung umständlich, die Stoffschichten absorbieren große Mengen von Emanation, so daß die radioaktive Wirkung dieser Kompressen eine sehr unvollkommene und unzuverlässige ist. Nach kurzer Zeit der Verwendung müssen die Kompressen gereinigt und sterilisiert werden, was mit Verlusten an teuren radioaktiven Substanzen verbunden ist.The compresses that come on the market are made with radioactive substances filled sacks made of fabric, which in turn are again put in a fabric cover. They are cumbersome to use, the layers of fabric absorb large amounts of emanation, so that the radioactive effect of these compresses is very imperfect and is unreliable. After a short period of use, the compresses need to be cleaned and sterilized, which is associated with losses of expensive radioactive substances is.

Radiologen haben zur Abstellung dieser Übelstände verschiedene Vorschläge gemacht, um auch dem Anwendungsgebiete radioaktiver Substanzen weitere Bahnen zu eröffnen, indem man versuchte, Pergament-, Gelatine-, Celluloidflächen usw. einseitig mit radioaktiven Stoffen in Lösungen o. dgl. zu bestreichen. Da es aber für die Wirkungsweise radioaktiver Präparate von allergrößter Wichtigkeit ist, daß die pro Quadratmillimeter ausgestrahlte Emanationsmenge jederzeit eine bestimmt dosierte und gleichbleibende sein muß, leuchtet es ein, daß diese Art der Anwendung den beabsichtigten Zwecken nicht entsprach, die radioaktiven Substanzen konnten nicht gleichmäßig auf der Fläche der Unterlagen verteilt werden und lösten sich auch von ihr ab.Radiologists have various suggestions for remedying these deficiencies made in order to open up further paths to the fields of application of radioactive substances open up by trying parchment, gelatin, celluloid surfaces, etc. on one side to be coated with radioactive substances in solutions or the like. But since it is for the The mode of action of radioactive preparations is of the utmost importance that the pro The amount of emanation emitted by a square millimeter is always a precisely dosed amount and must be constant, it is evident that this type of application is the intended one Purposes not met, the radioactive substances could not be evenly distributed the surface of the documents are distributed and also detached from it.

Die Erfindung besteht nun in dem Verfahren, Celluloid, Cellon und ähnlichen plastischen Massen bei der Herstellung radioaktive Substanzen zuzusetzen, innigst mit ihnen zu vermischen und dann Formen, wie Platten, Rohre, Stäbe usw., von verschiedener Stärke anzufertigen, wobei das Verhältnis der radioaktiven Stoffe zu den genannten plastischen Massen den beabsichtigten Zwecken entsprechend bestimmt wird. Den genannten nunmehr radioaktiven plastischen Massen kann man leicht jede gewünschte Form geben entsprechend den Körperteilen, wo sie angewandt werden sollen; sämtliche Teilchen der radioaktiven Stoffe sind von Celluloid, Cellon usw. umhüllt, ohne in ihrer Wirkung gehindert zu werden, man kann daher die radioaktiven Formen nach erfolgter Anwendung auch leicht reinigen, ohne hierbei Verluste an radioaktiven Stoffen zu haben.The invention now consists in the method, celluloid, and cellon to add radioactive substances to similar plastic masses during production, to mix intimately with them and then shapes, such as plates, tubes, rods, etc., of various strengths to be made, with the ratio of radioactive substances for the specified plastic masses determined according to the intended purposes will. The now radioactive plastic masses mentioned can easily be any give desired shape according to the parts of the body where they are to be applied; all particles of radioactive substances are encased in celluloid, cellon, etc., without being hindered in their effect, one can therefore use the radioactive forms After use, it can also be easily cleaned without any loss of radioactive substances To have fabrics.

Durch die Erfindung wird also die Ausstrahlung einer gewünschten bestimmten Emanationsmenge pro Quadratmillimeter Fläche erreicht und die Möglichkeit, radioaktive Stoffe anzuwenden, ohne Störung der Berufstätigkeit jedermann eröffnet; die Objekte können jedem Körperteil angepäßt werden, auch kann der Patient hierbei selbst die gewünschte Form herstellen, da Celluloid, Cellon u. dgl. bei Wärme -z. B. Eintauchen in heißes Wasser bildsam werden und nach Abkühlung -- auf Körpertemperatur - die gegebenen Formen beibehalten.The invention therefore makes the broadcast of a desired specific Amount of emanation reached per square millimeter of area and the possibility of being radioactive To use substances without disrupting their occupational activity; the objects can be adapted to any part of the body, and the patient himself can do the Produce the desired shape, since celluloid, cellon and the like. B. Immersion in hot water and after cooling - to body temperature - the Maintain given shapes.
