Abstract
Hospital patient temperatures and heartbeat rates are monitored by providing each patient with a battery powered transmitter containing a reference resistance and to which two sensor electrodes are connected. The first electrode includes a thermistor and is positioned in thermal contact with the patient's skin over the axillary artery. The second electrode is positioned in contact with the patient's skin proximate to the fourth intercostal left parasternal area of the patient's chest. A receiver, carried by a nurse, includes a magnetic actuator for closing a reed switch in a transmitter unit to activate the generation of data signals from that transmitter. The transmitter, when actuated provides an output of modulated, sequential data signals. The data signals are of a duration corresponding to a reference temperature, actual patient temperature, transmitter battery level, and patient heartbeat rate. The receiver includes demodulator circuitry and a microprocessor to provide numerical indicia quantitatively indicative of actual patient temperature and heartbeat rate. The microprocessor compares the demodulated data signals to allowable limits associated with each signal.
