ABSTRACT:
A tube-like reflector insert for a sensor is located in a rigid, light-absorbing sleeve that is closed on one side, and forms a two-part reflector body with the sleeve. A nut is glued onto the open side of the sleeve to enclose the reflector insert. The intravasal part of the sensor is guided in a protective tube having connector threads glued on on both sides. This protective tube is screwed onto the Y connector piece and the reflector sleeve with the nuts. The tip of the sensor is inserted with slight play into the sensor cavity of the reflector insert. The play ensures that sterilization gas can reach all of the intravasal surfaces. The reflector is attached to the sensor via a screw connection outside of the intravasal region, which ensures that the intravasal sensor part is not exposed to clamping stress. Free access for sterilization gas is possible at all intravasal surfaces of the sensor.
