1. A portable sleep apnea monitoring system comprising:

  • a belt comprising a substantially non-elastic, flexible material and having a distal end and a proximal end, the belt configured for secure placement generally encircling the abdomen and respiratory areas of a patient;

    a buckle assembly having a buckle and a first slot configured to receive said proximal end of said belt and a second slot configured to receive said distal end of said belt, the buckle assembly configured to expand and contract in response to respiration of the patient;

    a sensor assembly, disposed within said buckle and configured to detect repeatedly a plurality of expansions and contractions of said buckle assembly;

    an evaluator, disposed within said buckle, configured to receive a plurality of expansions and contractions signals from said sensor assembly, and configured to make calculations based upon a plurality of time intervals collected from the plurality of expansions and contractions of said buckle assembly, and thereby detect each sleep apnea event, and store the time of each sleep apnea event detected for later upload to an external device;

    a vibrator motor, disposed within said buckle and configured to be actuated by said evaluator when said evaluator determines that a sleep apnea event has occurred and thereby to inform the patient by vibration;

    an alarm, disposed within said buckle and configured to be actuated by said evaluator when said evaluator determines that the patient is unresponsive to said vibrator motor actuations; and

    a rechargeable battery, disposed within said buckle and configured to provide rechargeable power to the portable sleep apnea monitor.
