Abstract:
1. An electrotherapy apparatus using low and intermediate frequencies, comprising: a vacuum cup to be attached to a human body; a housing connected to an upper portion of the vacuum cup; a connection member adapted to connect the vacuum cup and the housing; a frequency generator on a printed circuit board that is included in the housing and includes circuits, including a sensor and a microcomputer; negative and positive electrode plates contained in the vacuum cup to be supported by springs, and adapted to come in contact with the human body while being operated to ascend and descend; connection terminals connected to the frequency generator and the springs to output frequencies to the negative and positive electrode plates; a connection terminal located in the vacuum cup to be connected to the sensor so as to operate the frequency generator during treatment; and a remote controller adapted to wirelessly control the frequency generator, wherein: the frequency output unit allows the low and intermediate frequencies, which are boosted to a voltage of 250 V while passing through the frequency adjustment unit, to be alternately output while passing through a flip-flop circuit composed of transistors and resistors, and the alternately output low and intermediate frequencies pass through output transistors, and then are alternately supplied to the negative and positive electrode plates.
