Abstract
An electronic thermometer probe assembly dseigned to provide an instrument which is highly accurate and convenient to use. The thermometer includes a probe section having a flexible plastic shaft with a thermistor mounted at its tip. A disposable probe sheath covers the thermistor and flexible shaft, and is replaced after each measurement to ensure that the instrument remains uncontaminated. The sheath is cylindrically shaped, and has an open end which extends onto a conically-shaped retainer for the sheath. The thermometer handle includes an axially displaceable section, movement of which dislodges the sheath from the retainer to enable it to be disposed of conveniently.
