LOW FREQUENCY THERAPY APPARATUS, BODY PART FOR LOW FREQUENCY THERAPY APPARATUS, AND COMBINATION OF PAD AND HOLDER FOR LOW FREQUENCY THERAPY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a low frequency therapy apparatus capable of preventing a potential difference from being formed between two exposed electrodes when a body part is detached from a pad.SOLUTION: A low frequency therapy apparatus 1 includes a pad 2, a holder 3, and a body part 4. The body part 4 includes an electric circuit 45 connected to a body part side electrode part 43, and an interlock mechanism 46 for opening/closing part of the electric circuit 45. The holder 3 includes an interlock pin 33 for activating the interlock mechanism 46. When the body part 4 is not attached to the holder 3, the interlock pin 33 is separated from the interlock mechanism 46, and the interlock mechanism 46 brings the electric circuit 45 into an open state. When the body part 4 is attached to the holder 3, the body part side electrode part 43 is brought into contact with a pad side electrode part 22 and conducted, the interlock pin 33 activates the interlock mechanism 46, and the interlock mechanism 46 brings the electric circuit 45 into a closed state.SELECTED DRAWING: Figure 4
