Description
Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to an insomnia therapeutic apparatus and a waveform modulation method thereof.
Background
Sleep disorders are prevalent in today's society, and at least 10% of people suffer from clinically significant sleep disorders (i.e., insomnia), which have a significant impact on public health. To date, insomnia is the most common form of sleep disturbance.
Most insomnia definitions include a description of symptoms with associated daytime discomfort that are specific to sleep. Sleep symptoms typically include difficulty falling asleep, difficulty maintaining sleep, inability to wake up much earlier than expected, or unrecoverable or generally poor quality sleep. Waking symptoms are associated with daytime discomfort, which relates to fatigue, drowsiness, emotional disturbances, cognitive difficulties, and social or occupational disturbances.
After the research of several generations, scientists have cracked the code of insomnia from the brain wave. The brain wave is mainly composed of four wave bands, delta (1-3 Hz), theta (4-7 Hz), alpha (8-13 Hz) and beta (14-30 Hz). The delta and theta waves are mainly present in sleep stages and are mainly used by scientists to study "sleep quality". When alpha waves in the brain waves of a person are strong, the situation shows that the person is relaxed, happy and sleepy at present, and the state is very suitable for falling asleep. When the beta wave in the brain wave of a person is strong, the person is proved to be in a state of high spirits and nervous spirit, and the person is obviously difficult to fall asleep.
Scientists find that insomnia patients can have insomnia through a large amount of data comparison, and the main common point is that brain waves have different degrees of abnormality. When the patient falls asleep, the beta wave is strong, the alpha wave is suppressed, the brain is always in a high state, and the patient cannot fall asleep even if lying in bed quietly. This is why many people fall asleep more hopefully and fall asleep more slowly, and the brain is more aware of this fact, the beta wave becomes stronger, and the people fall asleep more frequently and become a sink at night.
The prior methods for treating insomnia include drug treatment and physical treatment, and in the physical treatment, along with the development of bioelectronic technology, various electronic sleep apparatuses are appeared, which mostly generate a low-frequency bionic pulse signal by a pulse circuit, and are transmitted to the central nervous system of the brain of a patient through a non-contact coupling or contact electrode to induce the brain to sleep, for example, Chinese patent CN1187373A discloses a music bionic low-frequency electronic sleep apparatus, which induces and promotes the brain to sleep by transmitting music bionic low-frequency current generated by a pulse oscillation circuit, a pulse width modulation circuit, a music generation circuit and an output regulation circuit to the central nervous system through related acupuncture points of the brain through the contact electrode. Although the sleeping apparatus can play a certain role in hypnosis, because the sleeping apparatus only has a single function of inducing sleep, if a patient uses the sleeping apparatus for a long time, the human body can generate adaptability to the hypnosis signal and reduce the hypnosis effect, and the effect of treating insomnia cannot be achieved only by the pulse hypnosis signal playing the role of inducing sleep. The conventional insomnia therapeutic apparatus can only aim at most of patients who normally work and rest, is not suitable for some people with special work and rest time, and cannot well meet the individual requirements of the patients.
