The invention belongs to the technical field of
medical systems, and discloses a
system for treating
overactive bladder by applying a
time domain interference technology, and the
system comprises a
signal generator which is used for generating two paths of intermediate-frequency AC electric signals, the frequency range of the intermediate-frequency AC electric signals is 1 kHz to 10 kHz, and the
frequency difference of the two paths of intermediate-frequency AC electric signals is 1 Hz to 200 Hz; the
electrode array is connected with the
signal generator and is used for transmitting the two paths of intermediate-frequency alternating-
current electric signals to the
body surface of the sacral region of the patient; and the
control unit is connected with the
signal generator and is used for adjusting the
frequency difference, the amplitude and the treatment mode of the intermediate-frequency alternating-
current electric signal. According to the scheme, a
time domain interference technology is used, and intermediate-frequency current and multiple
electric field superposition are used, so that tissues can be better penetrated, targeted stimulation of deep sacral nerves is realized, and abnormal activities of the bladder are inhibited. The
system supports a static difference frequency mode and a dynamic difference frequency mode, the nerve adaptability is avoided, and the long-term
curative effect is improved.
