Neonatus deploys the Fetal & Maternal Monitor at each bed in the antepartum ward and the labour assessment unit. The monitor’s touchscreen display simultaneously traces the fetal heart rate FHR via a 1 MHz pulsed-wave ultrasound transducer with an autocorrelation processor, and the uterine contraction pressure via an external tocodynamometer TOCO belt. The system provides a trace resolution of 0.25 bpm and refresh rate of 4 Hz, ensuring that even subtle late decelerations and beat-to-beat variability critical markers of uteroplacental insufficiency are captured without interpolation artifact.

The monitor stores a 24-hour rolling trace buffer on solid-state memory; when the patient is admitted in labour, the buffer is automatically archived to the hospital’s perinatal information system PIS. Twin monitoring is supported via a dual-channel ultrasound module that uses frequency-division multiplexing to prevent cross-signal interference. A colour-coded alert system green for reassuring variability 6–25 bpm, accelerations present, yellow for suspicious variability ≤5 bpm for more than 40 minutes, red for pathological recurrent late decelerations, sinusoidal pattern is displayed on the bedside monitor and echoed at the central nursing station. The red alert triggers an immediate page to the on-call obstetrician.

Technical Note: The TOCO belt must be positioned at the uterine fundus and tensioned to a resting pressure of 10–15 mmHg on the monitor’s scale; over-tensioning compresses the maternal aorta and can produce a false contraction frequency. The ultrasound transducer’s crystal must be tested monthly for output power using a tissue-mimicking phantom; a power reduction exceeding 20 percent from the baseline indicates crystal delamination.

For rapid screening in community midwifery clinics and intermittent auscultation during low-risk labour, Neonatus provides handheld Fetal Doppler devices. The unit uses 3 MHz continuous-wave ultrasound and delivers audible fetal heart sound through an internal speaker, alongside digital readings refreshed every two seconds. Its IPX7 waterproof probe works underwater for water birth monitoring. The built-in rechargeable lithium battery offers 10 hours of constant use, with a warning light activating when 30 minutes of power remain.

This Doppler connects to clinic electronic health records through Bluetooth. One tap saves time stamped fetal heart rate data, gestational age and maternal posture. The system computes baseline heart rates from ten minute segments and alerts staff to slow heart rates below 110 beats per minute or fast rates above 160 beats per minute. For periodic labour checks, midwives listen for 60 seconds every 15 minutes in early labour and every five minutes in active labour, logging all data on tablet labour charts.

Technical Note: Only water soluble non spermicidal ultrasound gel is suitable for vaginal use. Oil based lubricants damage the probe’s latex safe outer layer. Factory set peak acoustic power stays under 20 mW per square centimetre. Annual testing with a calibrated hydrophone is required; any reading above 25 mW per square centimetre needs urgent maintenance.

For patients with abnormal cervical cytology, post-coital bleeding, or suspected cervical incompetence, Neonatus equips outpatient treatment rooms with digital colposcopes. This unit comes with binocular optics offering five magnification levels: 4×, 6×, 10×, 16×, 25×. It uses a 300-watt xenon lamp paired with a green filter to highlight blood vessel structures, plus a 5-megapixel CMOS camera for high definition photos and video recording. The equipment sits on a balanced floor stand with 1200 mm vertical movement and foot-controlled magnetic locks.

Standard examination steps include saline washing to view the transformation zone, 5% acetic acid application for a two-minute whitening observation, and Schiller iodine staining. Healthy mature squamous tissue turns dark brown while abnormal lesions show no color change. Built-in software supports Swede scoring and Reid Colposcopic Index evaluation. Clinicians record data on lesion edges, whitening degree, blood vessel features, iodine reaction and lesion size. Scores at five or above require targeted tissue sampling. A built-in distance marker helps biopsy tools reach target areas within two millimeters.

Technical Note: Prepare fresh 5% acetic acid solution weekly. Aged liquid loses potency and may miss serious lesions. Wipe the optical lens with microfiber cloth after every patient. Dry acetic acid residue cuts imaging contrast by twenty percent.

Neonatus integrates the Fetal and Maternal Monitor, the Fetal Doppler, and the Colposcope through a perinatal data gateway that sits on the hospital’s secure VLAN. All device readings, antenatal FHR traces, Doppler spot-check values, colposcopy images, and biopsy results, are time-aligned to the patient’s unique pregnancy identifier and plotted on a single, longitudinal Pregnancy Health Timeline. The dashboard is accessible from any authorized workstation via a secure web interface, with role-based views: midwives see current FHR and contraction patterns, obstetricians see high-risk flags and cervical pathology reports.

The rules engine generates automated alerts: a patient with a suspicious antenatal CTG yellow trace and a colposcopy finding of CIN II or higher receives a high-risk tag and is automatically scheduled for a combined obstetric-gynaecology clinic within 7 days. A missed appointment triggers a phone call alert to the community midwife. The dashboard’s trend view plots the evolution of FHR variability, uterine contraction frequency, and cervical length if transvaginal ultrasound data is imported from an external PACS, enabling prediction of preterm labour with a validated risk score algorithm.

Technical Note: The dashboard server requires a dedicated SQL database with 16 GB RAM and daily differential backups to an off site location. The NTP time synchronisation must be accurate to within 50 ms across all devices; a clock drift exceeding 100 ms can misalign CTG traces with maternal vital signs, producing erroneous deceleration attributions.

Neonatus configures the perinatal dashboard to generate automated referral letters: a patient with a non-reassuring antenatal CTG and intrauterine growth restriction flagged by fundal height measurement is referred to the fetal medicine unit with a pre-populated summary of the last three CTG traces and the colposcopy report. The PIS generates a structured “Pregnancy Handover Document” at 36 weeks, summarising all antenatal surveillance data for the labour ward.

For population health, the dashboard aggregates anonymised data across the health system: caesarean section rate for suspected fetal distress, positive colposcopy referral rate, and antenatal detection rate of small-for-gestational-age infants. The obstetric clinical director reviews these metrics quarterly against national benchmarks. A continuous audit loop identifies any missed cases of neonatal hypoxic-ischaemic encephalopathy and traces them back to antenatal monitoring gaps, feeding into a quality improvement plan.

Technical Note: All patient-identifiable data transmitted outside the hospital for cloud-based analytics must be de-identified using a hashed identifier and encrypted with AES-256. The dashboard’s population-health module is re-validated annually using a test data set of 1,000 known positive and negative cases; sensitivity for poor perinatal outcome must exceed 85%.
