1. A clinical thermometer comprising:
- a rigid case;
a monolithic flexible probe stem attached to the distal end of said case by a lap joint and extending away from said case;
said probe stem having a width and thickness both tapered outwardly away from said probe stem;
a sensor cap mounted to the distal end of said probe stem;
a temperature sensor positioned within said sensor cap and in thermal communication with said sensor cap;
a digital display in said case;
an electronic processor in said case operably associated with said temperature sensor and with said digital display to convert a temperature value detected by said temperature sensor into a read-out on said digital display; and
a power source operably associated with said processor for energizing the processor.

Abstract
A cost-effective electronic thermometer comprises a rigid case attached to a flexible probe stem in a lap joint. The flexible probe extends away from the case in a taper of both width and thickness. A sensor with sensor cap are mounted a the distal end of the probe stem. The temperature sensor is connected to an electronic processor with display that is positioned within case and powered by a battery.

9. A clinical thermometer comprising:
-
a rigid case; a monolithic flexible probe stem attached to the distal end of said case by a lap joint and extending away from said case;
said probe stem having a width and thickness both tapered outwardly away from said probe stem;a sensor cap mounted to the distal end of said probe stem and having a thermally isolated region delineated by a groove in said sensor cap and defined by a region of reduced cross-sectional area; a temperature sensor positioned within said sensor cap and in thermal communication with said sensor cap, said thermally isolated region being attached to said sensor; a digital display in said case; an electronic processor in said case operably associated with said temperature sensor and with said digital display to convert a temperature value detected by said temperature sensor into a read-out on said digital display; and a power source operably associated with said processor for energizing the processor.

15. A clinical thermometer comprising:
-
a rigid case having a top portion and bottom portion; a monolithic flexible probe stem attached to the distal end of said case by a lap joint and a retaining O-ring secured between said top section and said bottom section, said probe stem extending away from said case, said retaining O-ring being unitary with the probe stem; a sensor cap mounted to the distal end of said probe stem; a temperature sensor positioned within said sensor cap and in thermal communication with said sensor cap; a digital display in said case; an electronic processor in said case operably associated with said temperature sensor and with said digital display to convert a temperature value detected by said temperature sensor into a read-out on said digital display; and a power source operably associated with said processor for energizing the processor.
