<p>A clinical thermometer is described, based on the measurement of the infrared radiation emitted by the patient, in which the body temperature of the patient is obtained in a non-invasive way and (normally) without any contact between the thermometer and the patient. During measurement of the temperature, the thermometer (1) is put at a preset distance (d) from the body of the patient, a distance which is normally determined by an optical aiming system consisting of two converging rays of light (5). A thermometer according to the invention may be used to obtain the temperature of the patient also by contact.</p> |
