Abstract

A hygienic protecting device for an electronic thermometer includes: a disposable wrapping film wrapped on a front housing portion of an infrared thermometer, a fastening cup member made with a truncated cone shape and disposed about the disposable film on the front housing portion of the thermometer having a probe, the fastening cup member being mounted within the front housing portion for fastening the disposable film on the front housing portion and for preventing contamination when inserting the front housing portion and the probe into a person's ear canal, and a dust-proof thin film wrapped on the probe for shielding the probe for preventing contamination of the probe, with a fastening ring fastening the dust-proof thin film on the probe and a circular contacting ring disposed about the dust-proof thin film and retained between the dust-proof thin film on the probe and an inside wall in the front housing portion within an air space annularly defined between the probe and the front housing portion for minimizing the thermal transfer between the housing portion and the probe and for preventing the influence by ambient temperature, thereby ensuring a reliable temperature measurement in the ear canal of the person to be measured for a reliable and precise measurement of a body temperature.
