 EMI1.1 
 



   Bei der Untersuchung von   Körperröhrm   und Körperhöhlen, z. B. der Harnorgane oder dem
Magen, ist es zuweilen äusserst wichtig, dass auch Farbenunterschiede genau erkannt werden können, um z. B. leichte Entzündungen feststellen zu können oder beispielsweise bei Betrachtung der Blutgefässe die Venen von den etwas   röteren Arterien unterscheiden   zu können. 



   Es hat sich nun gezeigt, und hierin besteht die vorliegende Erfindung, dass auch besonders feine
Unterschiede in der Färbung der   Röhren- und Höhlenwandungen dann noch   erkennbar werden, wenn man in den Strahlengang der entsprechenden Geräte, der Kystoskope, Gastroskope usw. eine Mehrzahl von Lichtfiltern (also mindestens zwei) u. zw. verschieden gefärbte einschaltet. Es lassen sich dadurch noch Färbungsunterschiede   erkennb ? machen   die bei der Verwendung eines einzigen Filters nicht mehr erkennbar wären. Von diesen Filtern mag z. B. eins von der entsprechend gefärbten Wandung der zur Beleuchtung dienenden Glühbirne gebildet werden und ein zweites von einer in den Strahlengang des abbildenden optischen Systems eingeschalteten FIlterscheibe. Zweckmässiger z.

   B. wegen der leichteren Herstellbarkeit der Filterscheibe erscheint es jedoch, auf eine Färbung des beleuchtenden Strahlenbüschels zu verzichten und alle Filter in den Strahlengang des abbildenden optischen Systems einzuschalten. 



   In der Zeichnung ist in einer Ansicht ein der Erfindung entsprechendes Kystoskop dargestellt, das zwei Filter, ein hellgelbes   a   und ein hellblaues b hat, die beide im Strahlengang des abbildenden Systems liegen.

 EMI1.1
 



   When examining body tubes and body cavities, e.g. B. the urinary organs or the
Stomach, it is sometimes extremely important that color differences can also be accurately recognized in order to e.g. B. to be able to detect slight inflammation or, for example, to be able to distinguish the veins from the somewhat redder arteries when looking at the blood vessels.



   It has now been shown, and this is where the present invention consists, that particularly fine
Differences in the color of the tube and cave walls can still be seen if a plurality of light filters (i.e. at least two) u. between different colored switches on. Thereby, differences in color can still be recognized? make that would no longer be recognizable if a single filter were used. Of these filters, e.g. B. one of the appropriately colored wall of the light bulb used for lighting and a second of a filter disc switched into the beam path of the imaging optical system. More expedient z.

   B. because of the easier manufacture of the filter disc, however, it appears to dispense with a coloring of the illuminating beam and to switch all filters into the beam path of the imaging optical system.



   In the drawing, a kystoscope corresponding to the invention is shown in a view, which has two filters, a light yellow a and a light blue b, both of which lie in the beam path of the imaging system.
