Abstract
Die Erfindung betrifft medizinische Geraete, die in der Ophthalmologie Anwendung finden, insbesondere aber die Untersuchung der Augenhaemodynamik. Zwecks Erhoehung der Meszgenauigkeit des Kompressionsdrucks durch Verringerung der Druckkraft, ist das Fuehlergehaeuse mit einer zusaetzlichen Wand 1 ausgestattet, die eine Kontaktlinse darstellt, wobei die Waende hermetisch miteinander entlang des Umfangs verbunden sind und einen Hohlraum bilden, der mit einem Stutzen 2 gekoppelt ist; an der Grundwand sind durchgehende OEffnungen 4 zu finden.
