ABSTRACT:
A device for sensing heart and breathing rates in a single transducer and having electronic and filtering circuits to process the electrical signal generated by the transducer. The transducer is an electromagnetic sensor constructed to enhance sensitivity in the vertical direction of vibration produced on a conventional bed by the action of patient's heart beat and breathing functions and achieves sufficient sensitivity with no physical coupling between the patient resting in bed and the sensor placed on the bed away from the patient. The electronic circuits integrates the electrical energy generated by the sensor that pertains to cardiac and breathing information and sets off an alarm when pre-set circuits of these functions have been surpassed. The device has applications in monitoring SID Syndrome and non-ambulatory patients.
