Abstract
The electronic clinical thermometer of the present invention has a temperature sensing portion (3), a control signal generating circuit (2) for generating a control signal for controlling operation of each of structural elements, a converting circuit (4) for converting an output signal generated from the temperature sensing portion into a digital signal, a temperature measuring section (6) for measuring the temperature based on the digital signal, storage circuits (7) for storing and updating a maximum value of the temperature measured by the temperature measuring section in order. Data comparing circuits (8) are provided for comparing the temperature stored in the storage circuits with a present measured value. Temperature rise detecting means (21) is provided for detecting a rising amount of the temperature based on a compared result of the data comparing circuits, and a buzzer (103) is provided for informing the rise of the temperature based on a signal of the temperature rise detecting means. The temperature rise detecting means has a temperature change determining circuit (12) for generating a determining signal responsive to a temperature rising rate. The temperature change d…
