<p>The present invention provides a small sized temperature sensor for medical application for measuring local temperatures in the body and for measuring temperatures in an extracorporeal blood circulation circuit, eliminating the possibility of electric shock to the living body and featuring reduced cost, and increased resolution and reliability. That is, the invention relates to a temperature sensor for medical application comprising: a source of light; an optical fiber positioned at one end to receive light from said light source; a transducer near the other end of the optical fiber, said transducer being made up of at least two kinds of polymers that have dissimilar temperature dependencies of refractive index, a point of equal refractive index which is lower than 25 °C or higher than 45 °C, and a microphase separation structure; a reflection means for reflecting the irradiated light; and an arithmetic processing unit which receives the reflected light and calculates the temperature of the portion to be measured.</p> |
