RADIATION THERMOMETER WITH A ROUNDED MEASURING TIP AND A PROTECTIVE CAP

摘要

The invention relates to a radiation thermometer, especially an ear and fever thermometer, comprising a measuring tip (10) for the detection of infra-red radiation that is to be measured. Said measuring tip (10) consists of a head (12) with a dome-shaped front face enabling the measuring tip (10) to be inserted into the auditory canal of a user in a cant-free manner. Insertion is facilitated by a preferably flexible embodiment of at least one centrepiece (14) of said measuring tip. The centrepiece (14) can, for instance, be rod-shaped or conical. It has a widened base (16), whereby the penetration depth of the measuring tip (10) is limited in order to avoid injuries to the eardrum. The incident infra-red radiation is detected by means of at least one infra-red radiation sensor arranged in the head of the measuring tip or is transmitted to at least one infra-red radiation sensor (20) by means of at least one infra-red light guide (18). An infra-red lens (22) can be arranged in front of the at least one infra-red light guide in order to focus incident infra-red radiation. A protective cap that is adapted to the curved shape of the head (12) of the measuring tip is also described.
