Abstract
Disclosed is a bio-feedback type device for physical pain relief at childbirth, comprising a maternal-fetal monitoring module, a hand-grip pressure transducer, an electrical-stimulation wave group generator, an electrical-stimulation wave group output module and a childbirth pain-relief workstation. The maternal-fetal monitoring module is used for monitoring maternal-fetal vital-sign signals; the hand-grip pressure transducer is used to convert the degree of pain experienced by the mother into a pressure value; the childbirth pain-relief workstation combines and analyzes uterine contraction stress values from the maternal-fetal vital-sign signals with the hand-grip pressure values to produce electrical-stimulation wave group output parameters; on the basis of said output parameters, the electrical-stimulation wave group generator regulates the electrical-stimulation wave group and outputs same to the maternal body surface by means of the electrical-stimulation wave group output module and electrodes; the present invention is also provided with input and display modules to enable interaction between operators and equipment. The present invention is able to provide timely adjustment of electrical-stimulation wave group output parameters, the electrical-stimulation wave group signals taking into account the felt physical reception of different frequencies and waveforms of electrical stimulation pulses.
