| 摘要 |
The invention relates to body temperature measurement of humans and animals. More particularly, the invention provides a clinical electronic thermometer provided with a vocal output and transmitting means. The invention comprises an elongated housing, a thermistor being located at one end thereof and a piezoelectric speaker located adjacent to a grill in the housing and an electronic processing system connected to apply a known voltage to the thermistor for measuring the electrical resistance thereof, and to process this measurement and to send corresponding electrical pulses to the speaker to produce a vocal output of the measured temperature, the system further includes an analog/digital converter and ohmmeter connected to said thermistor, a microprocessor connected to said ohmmeter, a RAM memory connected to said microprocessor to retain at least the latest temperature measurement, a ROM memory connected to said microprocessor to permanently store pre-recorded analog data required for speech generation of words needed for producing temperature announcements, and at least one amplifier connected to said microprocessor; and finally a retaining device inside the housing for an electric storage battery, the device having connections to power said electronic processing system. |
