Problems solved by technology

Moreover, the output waveform of the method and device for labor analgesia mentioned above is a simple pulse signal, and the change of the pulse signal is only based on the change of pulse width, frequency and intensity. The output signal is single, and the analgesic effect is not ideal.
Moreover, organisms tend to develop "drug resistance" to a single electrical stimulus that acts on the body for a long time, resulting in the reduction of the analgesic effect of the originally effective analgesic stimulus signal after a long period of action, or even failure

Embodiment 1

[0056] Such as figure 1 As shown, the internal module of labor analgesia in this embodiment includes a maternal-fetal monitoring module, a hand-held pressure sensor, an electrical stimulation wave group generator, an electrical stimulation wave group output module, an input and display module, and a labor analgesic workstation; the maternal-fetal monitoring The module, the hand-held pressure sensor, the electric stimulation wave group generator, the input and the display module are respectively connected with the labor analgesia workstation; the electric stimulation wave group generator is connected with the electric stimulation wave group output module;

[0057] The maternal-fetal monitoring module is used to detect the vital signs of mother and fetus (referred to as maternal-fetal sign signals), and transmit the detected maternal-fetal sign signals to the labor analgesia workstation. The maternal-fetal sign signals include maternal ECG, blood pressure, Blood oxygen saturatio...

Embodiment 2

[0115] This embodiment is basically the same as Embodiment 1, except that the sampling data of the electrical stimulation wave group itself is stored in advance in the electrical stimulation wave group generator, and the output is selected according to actual needs, as follows: the two types of The sampling data of at least two electrical stimulation waves are pre-saved in the electrical stimulation wave generator, and the labor analgesia workstation is based on the uterine contraction pressure value of the maternal-fetal monitoring module and the manual pressure sensor of the hand-held pressure sensor. The grip pressure value is comprehensively analyzed, and the output type and amplitude of the electrical stimulation wave group are calculated according to the analysis results.

[0116] Such as Figure 8 As shown, the electrical stimulation wave group generator includes a wave group sampling database, a microcomputer system, a D / A converter and an amplifying drive circuit conn...

Embodiment 3

[0118] This embodiment is basically the same as Embodiment 1, except that the sampling data of the electrical stimulation wave group itself is stored in advance in the electrical stimulation wave group generator, and the output is selected according to actual needs, as follows: the two types of The sampling data of at least two electrical stimulation waves are pre-saved in the electrical stimulation wave generator, and the labor analgesia workstation is based on the uterine contraction pressure value of the maternal-fetal monitoring module and the manual pressure sensor of the hand-held pressure sensor. The grip pressure value is comprehensively analyzed, and the output type and amplitude of the electrical stimulation wave group are calculated according to the analysis results.

[0119] Such as Figure 9 As shown, the electrical stimulation wave group generator includes a wave group sampling data memory, an automatic scanning circuit, a D / A converter and an amplifying driving ...

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 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 provided 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.

Description

technical field [0001] The invention relates to the field of childbirth assistance, in particular to a biofeedback physical analgesia device for childbirth. Background technique [0002] In the medical pain index, labor pain (ie labor pain) ranks second only to burning pain. Severe labor pains will have a negative impact on the physical and mental health of mothers and babies; many mothers choose caesarean section because they cannot bear the severe labor pains, and even because of fear of labor pains, causing unnecessary trauma to the body. There are many reasons for labor pain, such as uterine paroxysmal contraction, elongation or tearing of uterine muscle fibers, uterine blood vessel compression and other stimuli uploaded to the pain center of the brain, which makes the mother feel severe pain; the fetus oppresses the birth canal when passing through the birth canal, especially It is the lower uterine segment, cervix, vagina, and perineum that cause damage and stretching...
