Title:
LOW FREQUENCY THERAPY APPARATUS
Document Type and Number:
Japanese Patent JP3711684
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a low-frequency therapy apparatus which prevents atrophy of organic muscles and reinforces the muscles fully by causing strong and quick contraction and relaxation of the organic muscles.
SOLUTION: A low-frequency reference pulse signal Vp2 such that it is raised from a low level to a high level after a predetermined delay time Td has elapsed since the time when the output of a step-up pulse signal Vp1 is started from a first pulse signal generating part 5, and that it is lowered from the high level to the low level after an output voltage Va has stabilized, is output to a switching part 3. When the low frequency reference pulse signal Vp2 attains the high level, the switch SW of the switching part 3 is switched to a contact (a), and when the low frequency reference pulse signal Vp2 drops to the low level, the switch SW of the switching part 3 is switched to a contact (b). Since an output voltage V0 which sharply rises to a voltage difference V1 can be fed, atrophy of the living muscles can be prevented and the organic muscles can be reinforced fully by causing strong and quick contraction and relaxation of the organic muscles.
