Abstract: An electromagnetic wave irradiation apparatus includes a housing having a hollow portion formed inside and an open lower side; a coil-type antenna with a spiral shape in the hollow portion and configured to emit electromagnetic waves; a window coupled to the open lower side of the housing; and a capacitance variation measurement unit configured to measure a capacitance variation of the coil-type antenna. The electromagnetic wave irradiation apparatus may further include a cooling unit configured to cool at least one of the window or the housing. The capacitance variation measurement unit includes a capacitance sensor with one side connected to the coil-type antenna and the other side connected to the ground.
Abstract: Disclosed is an extracorporeal shock wave medical device with high-frequency and low-frequency treatment functions. The extracorporeal shock wave medical device includes a body portion, a cylinder disposed inside the body portion, a moving portion which linearly moves inside the cylinder, a connecting portion disposed at the end of the cylinder and connected to the body portion to selectively collide with the moving portion when the moving portion moves, an impact portion connected to the connecting portion and configured to transmit an impact to the outside when the moving portion collides with the connecting portion, and a waveform transmitting portion electrically connected to the impact portion to transmit a high frequency or low frequency to the impact portion.
