  • Patent number: 6022140
    Abstract: A disposable cover for an infrared thermometer provides IR window isolation of handling and usage generated forces. The cover comprises a thin sidewall linked to the film window with a collar structure. The collar structure includes one or more characteristics that either isolate the film window from externally applied forces, or develops counter forces in a way that precludes film stretching and other transmission distorting effects. In a preferred embodiment, the probe includes retention ears and the cover includes a rim that cooperatively engages the retention ears. This combination of retention ears and an interlocking rim decreases movement of the cover along the probe axis. The cover of the present invention permits sanitary application of an infrared clinical thermometer without hindering reading accuracy or patient comfort.

  • Patent number: 5088834
    Abstract: A unitary probe cover for an infrared radiation thermometer has a frustum-shaped sheath which fits over the thermometer probe. A base, which is engageable with the probe, is formed integrally with and around the periphery of the proximal end of the sheath to hold the sheath over the probe. The sheath is made of an infrared transparent material and is formed to have a thinner distal end portion terminating in a thin window which passes infrared radiation through the probe into the thermometer.
