Abstract:
A disposable probe cover for a tympanic thermometer of the type having a radiant energy sensing structure for sensing at least one wavelength of radiant energy emitted by the eardrum, the probe cover having an insertion end for being inserted into an ear canal communicating with the ear drum and another end which remains outside of the ear canal so as to seal the ear canal, at least the probe cover insertion end comprising a deformable foam body defining a passage terminating in an opening, the passage accepting at least a part of the radiant energy sensing structure and communicating the radiant energy sensing structure with the opening, the probe cover further comprising a barrier that substantially occludes the passage, the barrier preventing ear canal contaminants from entering the opening while substantially allowing the radiant energy to pass therethrough and impinge upon the radiant energy sensing structure.
