PROTECTOR FOR A FIBRE-OPTIC CATHETER

The inventive protector for a fibre-optic catheter is used for examining an object in the form of a biological tissue, in particular the biological tiss ue of a living organism including the internal cavity thereof. Said invention provides with an efficient optical connection between the face of a distal e nd of said fibre-optic catheter and a studied object. The internal surface of t he protector window is embodied in such a way that the reversible adhesive contact with the face of a distal end of the fibre-optic catheter is formed. The external surface of the protector window is embodied in such a way that the reversible adhesive contact with the studied object is formed by the action of an axial pressure on the fibre-optic catheter arranged inside an envelope. Said protector window can be made of an elastoplastic material, fo r example of a hardened optical gel and at least in a two-layer form. The laye rs whose one surface forms the internal or external catheter window surface is made of an elastoplastic material, for example of a hardened optical gel, thereby excluding sliding of the catheter window along the surface of the studied object and simultaneously ensuring the efficient optical connection between the face of a distal end of said fibre-optic catheter and a studied object. The hardened optical gel can be in a gel-like or rubber-like form.
