The Design For The Biofeedback Therapy Apparatus Of Female Pelvic Floor

The biofeedback therapy apparatus of female pelvic floor is a biofeedback therapy system of female urinary incontinence. It's a therapy system based on the biofeedback technologies, the electro-therapy technologies and EMG sampled from female pelvic floor.In the thesis, the pathologies, the type, the therapy methods of the female urinary incontinence are introduced, especially the therapeutic mechanism of the biofeedback therapy apparatus of female pelvic floor and the hardware and software principle. At present, although the biofeedback technologies have been, to some extent, applied to treat the female urinary incontinence at abroad, there is no independent development and complete system in China. Combined with foreign and internal research resource and based on the biofeedback technologies, the electro-therapy technologies and EMG signal process, a biofeedback therapy apparatus of female pelvic floor integrated the biofeedback therapy and the electrical stimulation is developed.The hardware of the system involves the EMG pre-amplifier, the filter circuit, the analog-digital converter, MCU circuit, power circuit, sending and receiving infrared signal circuit, boost circuit, electrical stimulation circuit, etc. The EMG preamplifier circuit and other circuits are isolated by high-linearity octocoupier and isolated power that reject the industry interference and improve the security of the system. The amplifier and electrical stimulation circuit share the same electrode that can be operated easily by the customer.C8051F020 is the core of program control and the software of the system includes the LCD display module, the keyboard scan module, the gain control module, the infrared signal transmission and control module, the alarm module, the therapy pulse control module, etc. The main program is managed by a task queue that can achieve and answer external input signal in time. The program therapy pulse is easy to set the different therapy module according different patients, and the therapy effect is improved.
