Magnetic stimulator for neuro-muscular tissue

摘要

The magnetic stimulator includes a discharge capacitor (9) and a switching thyristor circuit (10) for allowing discharge of the capacitor (9) into a stimulating coil (11). At least one additional capacitor, e.g a reservoir capacitor (2) is charged by a power supply (1). Discharge of the reservoir capacitor is controlled by a series switch (3), which may be a thyristor (3) connected to an inductor (4). The circuit (3,4) is provided for pumping charge from the reservoir capacitor to a transfer capacitor, and a similar circuit (7,8a) pump charges from the transfer capacitor (5) to the discharge capacitor (9).
