The Refurbished Bistos BT-350 Fetal Monitor is an advanced cardiotocography (CTG) machine designed to monitor fetal well-being by measuring fetal heart rate (FHR) and uterine contractions. It features a 7-inch color TFT LCD display, waterproof Doppler probes, automated CTG analysis, twin-fetal monitoring capability, and extensive trend-data storage.
The BT-350 is designed for obstetric monitoring and provides a portable solution for fetal surveillance during pregnancy and labor.
Product Description
The Bistos BT-350 Fetal Monitor combines fetal heart-rate monitoring and uterine-activity measurement in a compact CTG platform. Its dual ultrasound Doppler probes can support twin monitoring, while the waterproof probe design makes the system suitable for environments where water-birth monitoring is required.
The monitor also provides cross-channel verification, helping distinguish fetal signals during twin monitoring and reducing the risk of confusing the two fetal heart-rate channels.
An integrated event marker allows the patient to indicate perceived fetal movement, while thermal recording provides a printed CTG trace for clinical review.

Fetal Heart Rate Monitoring
The BT-350 uses ultrasound Doppler technology to monitor fetal heart rate (FHR).
The supplied specifications identify an FHR range of:
30–240 bpm
The source also identifies 50–210 bpm depending on the selected mode/paper settings.
The monitor's dual Doppler configuration supports monitoring of twins, allowing two fetal heart-rate channels to be monitored where the appropriate configuration is used.
Twin Fetal Monitoring
The BT-350 can be configured with two ultrasound Doppler probes for fetal heart-rate monitoring.
This allows the system to support:
- Twin pregnancy monitoring
- Two fetal heart-rate channels
- Simultaneous fetal assessment
- Cross-channel verification
Uterine Contraction Monitoring
An external UC (uterine contraction) probe is included for monitoring uterine activity.
The UC sensor provides information about uterine contractions alongside fetal heart-rate measurements, forming the core components of cardiotocography monitoring.
7-Inch Color Display
The BT-350 features a 7-inch wide color TFT LCD display with a specified resolution of:
800 × 480 pixels
The supplied information also references large 7-segment LED display variants, indicating that display configuration may vary.
The color display allows users to view fetal monitoring information and CTG-related data during examination.
Automated CTG Analysis
The Bistos BT-350 provides automated CTG analysis, assisting healthcare professionals in evaluating recorded fetal-monitoring information.
Automated analysis is intended as a clinical support function and should not replace professional interpretation of fetal monitoring data.
Waterproof Doppler Probes
The supplied standard configuration includes two waterproof ultrasound Doppler probes.
The probes are rated:
IPX8
This waterproof construction supports fetal monitoring in water-birth environments when the appropriate clinical setup is used.
Thermal Recording
The BT-350 can produce a printed fetal-monitoring record using Z-fold thermal chart paper.
The supplied package includes thermal recording paper for creating physical CTG documentation.
Portability
The BT-350 incorporates a built-in carrying handle, making it easier to move between appropriate clinical areas.
The system also includes a standard backup battery configuration, allowing operation away from a direct AC power source depending on battery condition.
