1. An apnea preventive stimulating device comprising:

  • a respiration sensing circuit having sensor means for sensing the respiration of a living patient on which said sensor means is applied and developing a respiration detection signal representative of the detected respiration;

    respiration detection signal generator means connected to said respiration sensing circuit for receiving said respiration detection signal for producing a respiration identification signal developed only when breathing by the living patient is detected by said sensor means;

    an electric stimulating wave generating circuit connected to said respiration detection signal generator means having means for receiving said respiration identification signal including a respiration identification detector and electric stimulating wave generating means for generating electrical stimulating waves when apnea has continued an apnea time causing any trouble after detection thereof by said detection signal generator means;

    a stimulating circuit connected to said electric stimulating wave generating circuit and having a genioglossus stimulator to which the electrical stimulating waves are applied for genioglossus stimulation of the living patient;

    said electric stimulating wave generating circuit comprising control means including an amplifier to controlling intensity of the electric stimulating waves at a predetermined time from the living patient'"'"'s bedtime; and

    said control means comprising a sensitivity adjuster coupled with said amplifier to lower and to amplify the intensity of the electric stimulating waves and a timer connected to said sensitivity adjuster so that lowering of stimulation on the living patient by the electric stimulating waves during deep sleep of the living patient is effectively compensated for to wake up the living patient.
