Patent ID: 7387436

Claim:
In an ear-type clinical thermometer provided with a probe to be coupled to a measuring device, an ear-type clinical thermometer is characterized in that: said probe includes a probe body and a temperature measuring section connected to said probe body; said probe body is formed into a substantially L-shaped cylindrical member, an end of said probe body is coupled to said measuring device through a cable, and the other end of said probe body is connected to said temperature measuring section; said temperature measuring section includes a flange portion connected to said probe body and a distal end portion extending from the flange portion, and a sensor mirror is fitted in the interior of said distal end portion; said sensor mirror includes a cylindrical holder having a concave reflection surface in the interior, a coupling shaft extending from the rear side of said cylindrical holder, a first sensor for measurement and a second sensor for correction supported in a front space of said cylindrical holder by lead wires, respectively, and a cover sheathing a front surface of said cylindrical holder; said lead wires supporting said first and second sensors pass said temperature measuring section and probe body and are electrically connected to said cable, wherein said sensor mirror is a parallel light collector type mirror including a relatively short cylindrical holder having a concave reflection surface therein, a coupling shaft extending from a rear side of said cylindrical holder, first and second sensors supported by individual lead wires-at the front side of said cylindrical holder, and a protection cover sheathing the front side of said cylindrical holder; wherein said cylindrical holder is provided on the front and rear ends with notches to guide said lead wires from the front side of said temperature measuring section to the rear side of said probe body; and wherein said coupling shaft is provided longitudinally with a plurality of V-shaped grooves.
