ABSTRACT:
The present invention relates to a protective cover for a medical thermometer with a temperature probe region which is placed in direct contact with a patient during use. The cover is disposable and adapted to be removably secured to the temperature probe region such that the cover completely covers the temperature probe region, thereby physically isolating the temperature probe region from contaminants, and further includes means for effecting a visual change in the appearance of the cover when the thermometer is used. The cover is preferably formed of a thin, elastomeric, liquid-impervious material and its appearance changes upon exposure to one or more of moisture, pressure, galvanic skin response and skin temperature.
