KR-102962010-B1 - Brain stimulation device

Abstract

The present invention relates to a brain stimulation device, and more specifically, aims to provide a brain stimulation device capable of treating or activating and improving brain function by applying electrical stimulation to the brain non-invasively, wherein air is sprayed onto the scalp area where the electrodes come into contact when the cap is worn on the head, thereby allowing the electrodes to make proper contact while the scalp is exposed, thereby enabling treatment and activation and improvement of brain function. To this end, the present invention comprises: a cap having a dome-shaped frame so as to be worn on the head; a plurality of electrode parts installed and supported on the frame on the inside of the cap and transmitting electrical stimulation by contacting the scalp; a body having a nozzle that sprays compressed air supplied through the frame toward the scalp; and an electrode coupled to the body, the lower end of which is located lower than the lower end of the body.

Description

Brain stimulation device The present invention relates to a brain stimulation device, and more particularly to a brain stimulation device capable of treating or activating and improving brain function by applying electrical stimulation to the brain non-invasively. When signals are transmitted between brain neurons, an electrical current is generated, producing brainwaves. Brainwaves take on various shapes depending on the level of brain activity; the more actively the brain functions, the higher the frequency of the waves, while the more relaxed the brain is, the lower the frequency. These brainwaves include gamma waves, beta waves, alpha waves, theta waves, and delta waves. According to recent research, brainwaves—the electrical currents generated when signals are transmitted between human brain nerve cells—are known to have a significant impact on health. Based on this fact, brain stimulation devices have recently been developed that enhance students' learning effectiveness by improving concentration through the elimination of various factors that inhibit brain activity, or enable the general public to immerse themselves in meditation. As an example, in Public Patent No. 10-2020-0023798 (brain stimulation device), a plurality of electrodes are provided inside a cap worn on the head to provide AC stimulation and DC stimulation to the brain non-invasively, so that when a user wears it on their head, the electrodes come into contact with the scalp and a preset electrical stimulation value is applied through the electrodes, thereby stimulating the brain. Here, the electrode provided inside the cap must be in close contact with the scalp so that the correct electrical stimulation value, i.e., current, is applied, which can be used for treatment or to activate and improve brain function. However, according to the prior art, when a cap is worn on the head, it is difficult for the electrode to properly contact the scalp due to the hair, resulting in cases where only one electrode surface makes partial contact or no contact at all, which leads to a decrease in therapeutic or brain function activation capabilities. In other words, if the scalp is not exposed due to the thickness, density, or strength of the hair, the electrode will not be able to properly contact the scalp. <Prior Art Literature> - Republic of Korea Published Patent No. 10-2020-0023798 (Brain stimulator) FIG. 1 is a figure showing the structure of the brain stimulation device of the present invention. Figure 2 is a figure showing the shape of the electrode portion. Figure 3 shows the cross-sectional structure of the electrode portion.
