ApplicationNo. 05/969104 filed on 12/13/1978US Classes:600/26, SLEEP OR RELAXATION INDUCING THERAPY (E.G., DIRECT NERVE STIMULATION, HYPNOSIS, ANALGESIA)600/28Audio (e.g., heartbeat, "white noise", etc.)ExaminersPrimary: Kamm, William E.Attorney, Agent or FirmInternational ClassesA61M 21/00 (20060101)A61N 1/34 (20060101) A61N 1/32 (20060101) A61N 1/00 (20060101) AbstractApparatus for the electrophysiological stimulation of a patient is provided for creating an analgesic condition in the patient to induce sleep, treat psychosomatic disorders, and to aid in the induction of electrohypnosis and altered states of consciousness. The foregoing is achieved by repetitive stimuli in the patient for whom external influences, namely those of sight and sound, are intentionally excluded. The apparatus produces electrical stimulation of the patient in the form of a modulated wave which produces impulses in the delta, theta, alpha and beta regions of the brain's electrical activity, the electrical stimulation being accompanied by two sources of audio stimulation, one of which is a sinusoidal tone modulated by and synchronized with the electrical stimulation, and the other is derived from sound recordings. | |
