ABSTRACT:
A temperature, pulse and respiration detector is disclosed having a disposable oral probe with a thermopile mounted thereon. The thermopile comprises a plurality of hot junctions mounted near one end of the probe for insertion into the mouth. These hot junctions act as a temperature sensor and as one of the electrodes for pulse detection. The thermopile also comprises at least one hot junction spaced from the end of the probe for sensing nasal respiration. The other pulse detection electrode is mounted on a connector housing which holds the disposable probe. In use, the patient holds the connector housing with his left hand so that his thumb contacts the electrode mounted thereon and places the probe in his mouth. The patient's temperature and respiration are sensed by the thermopile and his pulse rate derived from the electrical activity of the heart sensed by the electrodes.
