Chapter1 Overview
1.1 Product Information
CADENCE providesaccurate and reliable monitoringinformation,usingnon-invasive
ultrasound Doppler,external TOCOtechnique.
RS-485/RS-232 communication portisbuilt,themonitorcan beconnected with
MFM-CNScentral monitoring systemviathis port.The monitorcanbe connected to
wireless network module via aDB9interface, and the wireless network module will
complete the data switch ofthe monitor andthe MFM-CNS central monitoring system.
Thedatacollectedand stored bytheCADENCE Fetal Monitor canbe analyzed and
printed bythe CADENCEInsightsoftware running on PC or MFM-CNS Obstetrical
CentralMonitoring System (CareVista) (Refer to MFM-CNSObstetricalCentral
Monitoring System (CareVista) User Manual andtherelevant informationofwireless
network module).

1.3 Fetal Monitor Operation Principle
Thefirstandthesecondgenerationfetalmonitors used previouslydetect FHRwith high
frequencycontinuous ultrasonicwaves. Continuous ultrasonic waves can’tcontrol
distancegate, and easyto beinterferedby other movementorgan and adult trunk blood
vessel movementsignal. Thefetus suffers moreultrasonic radiationthanpulsed wave.
Thethird generationfetal monitoradoptslowfrequencypulsedwave ultrasound,The
ultrasonic signal controlled byDoppler gatetransmitspulsed waves withspecific
frequencyto fetal heart,and it’s hardto beinterfered.
Thefirstandthe second generation fetalmonitors calculateFHRbymeasuring the
interval time ofDoppler signal peak values. Whilemodern fetal monitor calculatesFHR
using digital signal processing auto-correlationarithmetic. Auto-correlation operation
creates characteristic parameterviaprocessing Dopplerechosignal. Comparingnew
characteristicparameter createdbynewsignalwiththe former one, andobtainthedata
ofFHRdisplayandrecorder updating. Auto-correlation operation decreases additional
artificialsignal effectively,and onlyextractseffectiveecho signalthatcandeduce FHR.
Thedetection ofexternal TOCO is obtained byindirectmeasurement viadisplacement
transducer (TOCO) bindingatmaternal abdominalwall.
Operation Principleof Ultrasound Doppler FHR Monitoring
Ultrasoundtransducer is madeupofagroup ofquincunx multi-wafer piezoelectricity
transducers. TheCADENCE IIultrasound transduceris made upofninepiecesof
piezoelectric crystals withuniform distributed eight pieces constituting acircle, andone
lying atthe centerofacircle. Transducer transmits / receives switchunder thecontrol of
transmitting/receiving timingpulsegivenbysystemtimer.Receiver willbeclosed
during transmitting.Itcan receive Doppler frequency shiftinformation offetalheart when

transducer is inthe properplace. Magnifyand filter f0±fdDopplerfrequencyshift
ultrasound echoreceived byhardware system, thendemodulateit,the(f0±fd)- f0＝±fd
signal is obtained.After thesignal is filtered by Doppler frequencyshiftfilter,it is rectified
in full wave, and low-pass filtered. The envelope signalofDopplerfrequencyshiftis
extracted, and sentto multi-channel strobe.Itwill become digitalsignal via A/D
transform. FHRisobtained byDSPauto-correlation operation. The Doppleraudio is not
real sound, but an imitative soundcausedbyDoppler frequency shift change brought by
movementobject.TheFHRsignal range is 50-210BPM.
FHR signal processing flowis as follows.
TOCO Measurement Operation Principle
External TOCOmeasurementsub system uses thestraingauge bridge. Whenstrain
gauge suffers pressure,the bridge connection willlose balance, and produces an output
signal. Thepressurechanges veryslowly,so a low-pass filterissetto filter noise signal.
Itwillchangeintodigitalsignal viaA/D,and itsrelevantvalue iscomputed byDSP.We
take 100 gramforcesas 100 units, pressure measured byTOCO is contactforcesensor
processing.
