SINGLE USE INDICATOR FOR MEDICAL THERMOMETERS

摘要

The present invention relates to a protective cover (16) for a medical thermometer (10) with a temperature probe region (14) which is placed in direct contact with a patient during use. The cover (16) is disposable and adapted to be removably secured to the temperature probe region (14) such that the cover (16) completely covers the temperature probe region (14), thereby physically isolating the temperature probe region (14) from contaminants, and further includes means for effecting a visual change in the appearance of the cover when the termometer is used. The cover (16) 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.
