Using method of the present utility model and monitoring principle: in the moon is given a birth the first and second stages of labor observation processes, use this utility model mature.Earlier duck-billed speculum is probeed into portion's outer surface and be coated with aseptic lubricant, the handle portion of the hand-held duck-billed speculum of operator low probes into it transvaginal mouth and probes into vagina, under the guiding of observing the intravaginal image that photographic head obtained, to probe into portion's front end probes into and reaches cervix uteri mouth place, operator's manipulation handle portion and control the relative folding degree that upper and lower lobes two probes into portion, observe the degrees of expansion of cervix uteri mouth and the composition of presentation portion through the photographic head shooting, as presentation portion is fetal head, then judge fetal position by the tendency direction of observing the fetal head hair, as the disappearance of not breaking as yet of proamnion capsule, then can observe amniotic fluid character in the proamnion capsule; Under the more situation of the dialatation of cervical os, operator's manipulation probes into portion's front end places the cervix uteri mouth maximum separation radial line of expansion respectively with open configuration two edge places with upper and lower lobes two, variable angle between leaf leading portion and inferior lobe leading portion is gone up in the displacement transducer induction, the length of portion is equal to and be given value because upper and lower lobes two probes into, then can go out the upper and lower lobes two of set and probe into distance between portion's front end by being placed in computed in software in the computer in the cervix uteri mouth two edge places of expansion, dialatation of cervical os degree can be on computers shown and record in the mode of numerical value or figure thus, under the less situation of dialatation of cervical os degree, can probe into the judgement that the comparison of the cervix uteri mouth of the width of portion's front end and expansion draws dialatation of cervical os degree by upper and lower lobes two; Anemia of pregnant woman's dorsal position of making even, in the uterine contraction intermission, ergometer is placed on the bed surface, with the level position make feeler lever front end transvaginal mouth probe into vagina and make its contact fetal head, in the uterine contraction phase, the operator pushes down the ergometer body with subordinate, make it fixed-site, the dynamics that fetal head due to the uterine contraction power is pressed to birth canal at the bottom of the basin changes will be by the feeler lever mechanical conductive to the body pressure sensor, and then can be on computers shown and record in the mode of numerical value or figure, fixed mount constitutes cover with screwed pipe on screw rod and the body and inserts annexation, can set up body apart from the distance between base by tuning screw rod, determines that thus the feeler lever that is fit to probes into the high and low position of vaginal orifice; The blood oxygen saturation monitoring instrument probe, its light emitting diode and light sensitive diode are placed in reversible manner in the draw-in groove of the portion that probes into front end of leaf on the duck-billed speculum or inferior lobe, there is certain interval in both, as 1～2cm at interval, it is contacted with fetal head, light emitting diode and light sensitive diode can luminous reflectance and the principle of reception predict the in-house blood oxygen saturation in fetal head place, by the blood oxygen saturation monitoring module of settling in the computer with software for display is shown and record, test shows: the existence of fetus hair does not have obvious influence to oxygen saturation measurement; Duck-billed speculum upper and lower lobes two portions of probeing into are probeed into vagina and contact with the level position with fetal head presentation portion, because last leaf probes into the graduation mark that portion's outer surface is provided with the sign distance, but the scale value at observed and recorded vaginal orifice leading edge place, by comparing certain hour scale value reading at interval, can predict the decline degree of fetal head in birth canal, clinical research proves: traditional fetal head decline degree judges that reference point is the imaginary line of both sides between ischial spines, touch earlier undisguised property minimum point and draw judgement by the intravaginal touch with the subjective comparison of aforementioned imaginary line, accuracy is relatively poor, the vaginal orifice leading edge is the soft tissue sign, because of pubic symphysis and both sides pubic branch position relative fixed in birth process of bone near it, can be preferably as the judgement reference point of dynamic monitoring fetal head decline degree.

The clinical effectiveness that this utility model is useful: this utility model makes that reflection stages of labor important index such as fetal head decline thrust is able to digital monitoring due to dialatation of cervical os degree, fetal presentation decline degree, fetal position situation of change and the uterine contraction, changed traditional by the subjective judgment pattern of checking with the non-digitalization vaginal touch, and can make the blood oxygen saturation index that circulates around the fetus obtain monitoring, making science, objectivity and the accuracy of childbirth monitoring obtain the change of matter.Clinical research shows: the operation of implementing monitoring with this utility model is simple and easy to do, and practise midwifery person need not to experience long-term training and just can expertly grasp the monitoring operation and obtain aforementioned important indicator, and is of the present utility model cheap, possesses popularizing application prospect.
