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 analyses 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.
