摘要:
Disclosed is a detachable combination health-care and treatment instrument has a optimal matching parameter, fits the shape of different parts of body, can be used in several parts of body simultaneously, and possesses a energy field multiplexed by a permanent magnetic field, a pulse magnetic field, a thermal effect and far infrared rays. It relates to a health-care and treatment instrument. The instrument includes a main unit, panel units and soft units. In the case of the panel unit, the magnetic induction intensity is 100˜130 mT, the inductance of the coil and the core is 30˜80 mH, and the impedance of the heater panel is 3˜5&OHgr;. In the case of the soft unit, the magnetic induction intensity is ≧100 mT, the inductance of the coil and the core is 30˜80 mH, and the impedance of the sheet heater is 7˜9&OHgr;. Since the present invention has a plurality of panel units and soft units, several parts of body can be positioned into a multiplex energy field simultaneously so that the communication effect of the venation gets better. Furthermore, since it has the optimal matching parameter and adapts the said multiplex energy field to the body so as to achieve the perfect effect of jingluo conduction and health care.
