Wearable pulse modulation magnetoacoustic stimulation device for improving cognitive impairment of old people

Abstract

The invention provides a wearable pulse modulation magneto-acoustic stimulation device for improving cognitive impairment of old people, which is a head-mounted portable magneto-acoustic stimulation rehabilitation assistive device and comprises a coil, a loudspeaker, a head sleeve, a power supply, a voltage converter, a relay, a controller, an audio module, a cable and a strap. The system generates a subthreshold low-intensity pulsed magnetic field of a gamma frequency band and a modulated sound signal of a theta frequency band, and compared with single magnetic stimulation, magnetoacoustic coupling can improve the effectiveness of nerve regulation and control. The low-intensity pulsed magnetic field acts on the frontal lobe, the low-frequency modulated sound signal acts on the temporal lobe, and the magnetic stimulation and the sound stimulation coordinate to adjust neural activity, so that the inhibited electroencephalogram signal of the gamma-frequency band of a patient is enhanced, the electroencephalogram activity of the theta-frequency band is recovered to be normal, and the cognitive disorder is improved. The system can be used by a patient independently or with the help of other people, the problem that the patient is inconvenient to see a doctor is solved, and the system is a novel home nursing technology and a novel device which are safe, efficient, portable and wearable.

Description

technical field [0001] The invention belongs to the fields of neuromodulation technology, magnetic-acoustic stimulation technology and wearable rehabilitation treatment system, and in particular relates to a wearable pulse-modulated magnetic-acoustic stimulation device for improving cognitive impairment of the elderly. Background technique [0002] With the deepening of my country's population aging, the number of people suffering from senile cognitive impairment continues to increase, which has brought serious burdens to families and society. In elderly patients with cognitive impairment, the EEG activity in cognition-related brain areas is inhibited. By applying electrical, magnetic, light, sound and other physical factors to the human brain for neural regulation, the inhibited EEG activity can be activated and strengthened. The specific manifestations of cognitive impairment in the elderly include mild cognitive impairment and Alzheimer's disease. Studies have shown that ...

AI Technical Summary

Problems solved by technology

The use of magnetic stimulation and acoustic stimulation is non-invasive. At present, transcranial magnetic stimulation has been used to treat mental and neurological diseases in clinical practice, but a single magnetic stimulation can only stimulate the cortex to regulate relatively superficial neural activities, while acoustic Stimulation modulates neural activity in the hippocampus between the thalamus and medial temporal lobe, deep in the brain

In order to further improve the effectiveness of neuromodulation, some devices use magneto-acoustic combination or apply multi-physical factor stimulation. magnetic stimulation and focused ultrasound stimulation, but due to the high stimulation intensity, professional guidance and operation are required; Chinese invention application CN113144437A (a kind of sound and light therapy equipment for improving the cognitive function of Alzheimer's disease) is aimed at Alzheimer's disease , using sound and light stimulation, the use scene is a hospital or a rehabilitation center, neither of which can be wearable and home-use
