Heat conductive structure of a non-mercury non-electronic clinical thermometer

A heat conductive structure for a thermometer having a structure with temperature indication markings comprising:

• a probe structure with a thermal conductive surface;
• a temperature indication portion disposed adjacent to the probe structure;
• a reversible temperature-sensitive color changing layer, formed on the temperature indication portion to overlap the structure of the temperature indication markings, wherein the probe structure is adapted for sensing the thermal contact surface to conduct heat flow to the reversible temperature-sensitive color changing layer, producing a sensed temperature and a color changing zone of the reversible temperature-sensitive color changing layer in response to the sensed temperature thereby exhibiting a corresponding temperature value;
• wherein the temperature-sensitive color changing layer has a first color state in a prescribed temperature range and the first color state is employed to mask the structure of the temperature indication markings.
