<p>PURPOSE: To supply minute movement removing pulses of such a size as calculated to induce a prescribed minute movement removing electricity in a patient by stopping charging the condenser if the electric charge is enough to supply electricity to the patient. CONSTITUTION: This minute movement remover 10 has an energy storing device 12, a paddle 14 to give electric impact on a patient 16 from a condenser, and an energy source 18 to charge the condenser. A detector 20 is to detect the electric charge stored by the condenser, and send the data to a comparator/charge control circuit 22, so charging the condenser can be controlled. The electric charge of the condenser is sampled through a 1000 to 1 voltage dividing circuit network 20, and converted to digital data by a second A/D converter 56. The output from the second A/D converter 56 is regularly stored in a condenser voltage register 58, and compared with a limiting voltage value from the comparator/charge control circuit 22 stored in a voltage limit register 52. As long as the voltage of the condenser is lower than the stored limiting voltage value, the condenser voltage control circuit 22 can continue to charge the condenser to the energy source 18, and when the voltage of the condenser exceeds the limiting voltage value, charging is stopped.</p> |
