  • Low frequency medical device, method therefor, program and recording medium
    Patent number: 7949406
    Abstract: Quantity and time for medical operation are measured after starting the medical operation (step S1). Parameters in a parameter protection mode and parameters in a standard mode are compared so as to determine whether or not contents in the parameters coincide and whether or not five minutes passes (step S2). If five minutes do not pass, it is detected whether or not a power supply switch is turned off (step S4). If it is not turned off, the operation returns to the step S1 so as to determine whether or not the power supply is turned off within five minutes in steps S3 and S4 while measuring the quantity and the time for the medical operation. If five minutes passes without turning off the power supply, data for the quantity and the time for the medical operation are loaded in a memory (step S5). After that, the operation is completed.
