Filed: 1991-03-07
Abstract: PURPOSE: To thermally insulate the optical path of a probe from other heat sources or low temperature sources with which the probe in use may contact, or from thermal energy transmitted from the probe. CONSTITUTION: A thermal insulation device for a probe 16 with a protruded biomedical thermometer 11 has an air gap as a thermal insulator and a heat releaser 20 placed between the surface of the probe 16 and an optical path through the probe 16. The heat releaser 20 surrounds the optical path such as a waveguide tube 18 and acts so as to avoid the temperature fluctuation by dispersing heat over the whole length of the waveguide tube 18. Furthermore, the heat releaser 20 has sufficient mass for a large heat content, and delays the heat progress reaching the waveguide tube 18 or leaving this tube till the measurement by the biomedical tool is completed. The heat releaser 20 is converted with a protecting member material forming a closed air space between the heat releaser 20 and the outer surface of the probe 16.  This air gap combined with the heat releaser offers relative thermal insulation of the optical path going through the probe 16.
