ABSTRACT
Obiective To descript the method and the equipment of implantable single-point electric stimulation which is designed to continionsly and effectively treat the chronic diseases that harm the people's health. Methods The system is constructed with two parts, outside power transfer and implanted power receiver. The bypass capacitor of transistor and transformer inductor make up of power transmitter, which is half series resonant. With using transeutaneous power transform, the efficiency of this transform is studied. Experiments choose proper transmitting parameters transformer winding is a 20 turns hollow coil of 35mm diameter, and the frequency is 150-200 kHz; the receiver winding is a 100 turns hollow coil of 10ram diameter. Results Finally the completed prototype of the system and the receiver can generate about 5-10 mA current to stimulation tissue with 5mm gap between receiver and radiator, which meets the requirement of application.ConclusionThis instrument can be used in all kinds of single-point stimulation experiment.
