Description

Helmet-type magnetic stimulation device The present invention relates to a helmet-type magnetic stimulation device, and more specifically, to a helmet-type magnetic stimulation device that performs non-invasive treatment by applying a magnetic field to the scalp or transcranial region of the human body. Transcranial magnetic stimulation (hereinafter referred to as 'TMS') is a brain stimulation technique that activates or inhibits nerve cells in specific areas of the brain using local magnetic field waves induced on the surface of the head outside the body. The principle of TMS is to generate a magnetic field of strength of several Tesla by applying a strong electric current to an electromagnetic coil. It is a method of stimulating the brain by transmitting the fluctuating energy of these magnetic field waves to the brain, thereby inducing depolarization in nerve cells within a range of several centimeters below the coil. TMS is a representative non-invasive brain stimulation technique, and its therapeutic applications are being actively researched for conditions such as depression, insomnia, obsessive-compulsive disorder, movement disorders, dementia, and brain dysfunction that do not respond well to drug therapy or psychotherapy. Typically, the recommended treatment time for TMS is about 20 minutes, once a day, five days a week, requiring high-frequency treatment. For example, when magnetic stimulation therapy of about 20 to 50 minutes per day is repeatedly applied over several days to central nervous system diseases such as stroke or spinal cord injury, effects of neuroplasticity, neuroregeneration, and functional recovery have been reported. However, since existing TMS treatment devices are not portable, it is difficult to meet such treatment cycles given the conditions of the domestic medical market. Therefore, there is a need to introduce miniaturized TMS treatment devices that can be easily used at home, and accordingly, portable or home-use devices are currently being developed. Although several portable TMS treatment devices are being developed, components such as coils and cases are heavy, which can place a strain on the neck or shoulders when worn for extended periods. This weight issue poses a significant inconvenience, particularly for the elderly or physically frail patients. Additionally, the inability to effectively dissipate heat generated by the coils can lead to overheating problems. These issues of weight and heat generation make continuous use of the device difficult and hinder the full benefits of stimulation therapy during long treatment sessions. In particular, since these devices are worn directly on the head, comfort and lightweight design are essential factors for prolonged use.
