Abstract
Abstract An elongated temperature sensing probe of an electronic thermometer having a movable collar and an elongated probe terminating with a probe tip including a heat sensing element. A disposable cover having an elastic cylindrical side wall mounted on a closed end member is latched to the probe to enclose the tip and surround an elongated portion of the probe. The closed end member has a thin cone-shaped thermal window which is deformed into surface engagement with the probe tip when the cover is mounted on the probe. The probe collar and open end section of the cover have coacting releasable latch structure holding the cover in assembled relation with the probe.
