The tube-like reflector insert (25) is located in a rigid, light-absorbing sleeve (26) that is closed on one side, and forms the two-part reflector body with the latter. A nut (24) is glued onto the open side of the sleeve (26). The reflector insert (25) is enclosed as a result. The intravasal part of the sensor (11), which must be kept sterile, is guided in a protective tube (22) having connector threads (21, 23) glued on on both sides. This protective tube (22) is screwed onto the Y connector piece (13) and the reflector sleeve (26) with the nuts (12, 24). The tip of the sensor (10) is inserted with slight play into the sensor cavity of the reflector insert (25). The play ensures that sterilization gas can reach all of the intravasal surfaces. The attachment of the reflector to the sensor takes place by way of the screw connection (12, 21) outside of the intravasal region. The screw connection (12, 21) ensures that the calibration reflector device is connected with the sensor without exposing the intravasal sensor part (11) to clamping stress. Free access for sterilization gas is possible at all intravasal surfaces of the sensor.
