ABSTRACT:
A sanitary protective cover or sheath for the ear canal probe of a tympanic thermometer. The speculum has a generally tubular body portion and an infrared transparent membrane attached to and sealing the forward end of the body portion. While the tubular body portion is being injection molded of plastic material such a polypropylene or polyethylene, a film of a similar plastic material is mated to the forward end of the membrane and is thus severed from the film and one side thereof thermally bonded to the tubular body portion. At the same time a bonding ring of roughly the same diameter as the forward end of the tubular body portion is injection molded. The ring is thermally bonded to the opposite side of the film in alignment with the forward end of the tubular body portion.
