ELECTRIC THERAPEUTIC EQUIPMENT HAVING LOW FREQUENCY TREATMENT PART AND HYPERTHERMIA PART

摘要

PROBLEM TO BE SOLVED: To prevent the human body from receiving an electric shock by a current flowing to the ground through the human body in electric therapeutic equipment constituted so that a hyperthermia device and a low frequency treatment device are integrated to use the power supply on the side of a low voltage signal circuit in common and can be respectively controlled by one controller. SOLUTION: A safety circuit part is provided so as to prevent a current from flowing to the ground from a commerical power supply part 8 through a low frequency treatment director 2. For example, the safety circuit part is constituted of the first switch element group 30 provided between a hyperthermia circuit part and the commerical power supply part and the second switch element group 31 provided between the low frequency treatment director 2 and a low frequency treatment circuit part. The first and second switch element groups are connected to a control part 6 and this control part turns the first switch element group OFF while turns the second switch element group ON when low frequency treatment is performed and turns the first switch element group ON while turns the second switch element group OFF when hyperthermia treatment is performed.
