Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Das in der Zeichnung veranschaulichte Instrument (Werkzeug) dient zur Beleuchtung einzelner Theile der menschlichen Körperhöhlen.The instrument (tool) illustrated in the drawing is used to illuminate individual Parts of the human body cavities.

Das Werkzeug besteht aus einer gebogenen Röhre a, welche an ihrem einen Ende offen ist und eine Anlage c für das Auge besitzt, während an dem anderen geschlossenen Ende im Innern der Röhre eine elektrische Glühlampe b angeordnet ist. Diese Glühlampe wirft ihr Licht zu einem Fenster d, welches entweder offen oder durch Glas verschlossen sein kann. Dieses Fenster wird an die zu belichtende Stelle gelegt.The tool consists of a curved tube a, which is open at one end and has an attachment c for the eye, while an electric incandescent lamp b is arranged inside the tube at the other closed end. This incandescent lamp throws its light to a window d, which can either be open or closed by glass. This window is placed at the point to be exposed.

Um das Licht an der zu besichtigenden Stelle zu sammeln, kann eine Glasscheibe, ein Prisma oder ein Linsensystem eingeschaltet sein.In order to collect the light at the point to be visited, a pane of glass can be used Prism or a lens system must be switched on.

Gegenüber bekannten Einrichtungen (z. B. derjenigen von Nitze) bietet das Werkzeug den wesentlichen Unterschied, dafs die zu belichtende Stelle zwischen dem Auge und der Lichtquelle liegt und somit den Vortheil, welcher auch theilweise der gebogenen Form der Röhre zuzuschreiben ist, dafs das Auge nicht durch unmittelbar einfallende (nicht gebrochene) Lichtstrahlen geblendet wird. Statt des einen Fensters können auch mehrere angeordnet werden,Compared to known devices (e.g. those from Nitze), the tool offers the essential difference that the place to be exposed is between the eye and the Source of light, and thus the advantage, which is also partly due to the curved shape of the It is to be ascribed to the tube that the eye is not exposed to directly incident (not broken) Beams of light is blinded. Instead of one window, several can be arranged will,

Claims (2)

Patent-Ansprüche:Patent Claims: ι . Ein Instrument zur Beleuchtung menschlicher Innentheile, bestehend aus einem knieförmig gebogenen Rohr, an dessen Kniefläche ein Fenster oder eine Oeffnung d sich befindet, während der abgebogene Theil des Rohres die Lampe trägt, deren gesammtes Licht durch die Innenwände des abgebogenen Rohrtheiles nach der Oeffnung oder dem Fenster d reflecfirt wird, zum Zweck directer vermehrter Beleuchtung von Flächen, welche an der Knieöffnung, anliegen , bei gleichzeitiger. völliger Freilage des Beobachtungsrohres für Instrumente und Auge und unter Fortfall der störenden Lichtstrahlen für das letztere.ι. An instrument for illuminating human inner parts, consisting of a knee-shaped bent tube, on the knee surface of which there is a window or an opening d, while the bent part of the tube carries the lamp, the entire light of which passes through the inner walls of the bent tube part after the opening or the Window d is reflected, for the purpose of direct increased illumination of surfaces which are adjacent to the knee opening, with simultaneous. complete exposure of the observation tube for instruments and eyes and with the elimination of the disturbing light rays for the latter. 2. Ein Instrument nach Anspruch 1., bei welchem das abgebogene, die Glühlampe enthaltende Rohr durch eine durchsichtige Fläche (Linse) abgeschlossen ist.2. An instrument according to claim 1, wherein the bent containing the incandescent lamp Tube is closed off by a transparent surface (lens). Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
