Abstract
Die Erfindung bezieht sich auf medizinische Geraete, die in der Ophthalmologie zur Messung des intraokularen Druckes und der hydrodynamischen Kennwerte Verwendung finden. Zwecks Erhoehung der Meszgenauigkeit und -sicherheit durch Verbesserung der Fuehlerzentrierung, ist das Gehaeuse 1 des Tonometers mit einem Griff 16 mit Hilfe eines elastischen Elementes 17 verbunden, das in das Tonometer eingefuehrt ist, das ebenfalls mit einem Kontaktelement und zwei Huelsen versehen ist, die koaxial zur Sesibilitaetsscheibe 10 und gegeneinander verschiebbar angeordnet sind, dabei weist die innere Huelse 11 eine flache Arbeitsflaeche auf, waehrend die entgegenliegende Flaeche mit einem Stoeszel ausgestattet ist, der mit dem Kontaktelement wechselwirkt; die Arbeitsflaeche der aeuszeren Huelse 14 stellt sich konkav in Form eines Kugelsegments dar.
