Abstract
A unitary disposable sanitary sheath is intended to cover a combination temperature and respiration sensing probe so as to not adversely affect the sensing properties of the probe. An elongated portion is provided having very thin walls to surround the temperature sensing means yet to not greatly affect its thermal conductivity characteristics. A cup-like scoop is provided to channel the respiration exhalation into the probe inlet and the scoop also having a flattened portion which is located at the place normally clasped by a patient's lips to prevent rotation of the probe and sheath during a measurement operation.
