<p>A medical infrared thermometer for measuring a patient's body temperature by sensing infrared radiation emitted from the patient's tympanic membrane has a thermometer housing (1) and a probe assembly (2). The probe assembly (2) comprises a hollow, substantially tubular probe body (3), a heat sink (5), an infrared sensor (7) and a radiation shield (10). The infrared sensor (7) is arranged in a sensor container (13). The radiation shield (10) is in tight contact with an inner surface (11) of the probe body (3). A gap (12) is formed between the container (13) and the radiation shield (10). This design allows a reduction of the outer diameter of the tip (15) of the probe body (3) which allows to use the thermometer (1) with pediatric patients. <IMAGE></p> |
