ABSTRACT:
An electronic medical thermometer employs disposable thermocouple probe strips to produce substantially instantaneous readings. The disposability of the entire probe strips eliminates the danger of patient-patient or patient-practitioner cross-infection. The probe strips can be formed as individual strips or as a roll. Each strip has a substrate, thermocouples on the substrate, and a cover layer. The tip of the probe strip is uncovered so that the thermocouple junction is exposed. A feed device advances the next probe strip into place for a temperature measurement. Circuiting for this includes a cold junction compensation circuit, followed by an A/D converter, and a digital display.
