Fetal Monitor M2736A Avalon FM20/30 TOCO Ultrasound Probe With 90 Days Warranty
The M2736A Avalon FM20/30 TOCO Ultrasound Probe is a critical component of Avalon FM series fetal monitors, designed for monitoring maternal and fetal health during pregnancy and labor. Below is a detailed introduction based on the search results:
Key Features and Functionality
Compatibility:
- The M2736A probe is compatible with Avalon FM20/30/50 fetal monitors 4915. These devices are widely used in intrapartum care for tracking fetal heart rate (FHR) and uterine contractions (tocodynamometry, or TOCO).
- Dual Monitoring Capability:
- Combines ultrasound technology for fetal heart rate detection and TOCO sensors to measure uterine contractions. This allows simultaneous tracking of fetal well-being and maternal labor progression 15.
- Smart Pulse Technology:
- proprietary Smart Pulse and cross-channel verification ensure accurate differentiation between maternal and fetal heart rates, reducing false readings caused by signal overlap . This is critical in avoiding misinterpretations during high-risk deliveries.
- Safety and Accuracy:
- Designed with low ultrasound power output to ensure safety for both mother and fetus . However, improper use (e.g., misapplying the ultrasound transducer to the mother instead of the fetus) can lead to errors, as noted in an adverse event report involving the FM50 model .
- Technical Specifications
Parameters:
- External Fetal Monitoring: Supports ultrasound (US) and tocodynamometry (TOCO).
- Internal Monitoring: Optional integration with DECG (direct electrocardiography) and IUP (intrauterine pressure) sensors.
- Twin/Triplet Capability: Standard for twins, optional for triplets.
- Data Storage: Buffers up to one hour of monitoring data for retrospective analysis.
- Battery Life: Up to 4 hours with optional battery support.
Clinical Applications
- Intrapartum Monitoring: Used during labor to assess fetal heart rate variability and uterine contraction patterns, aiding in decisions about delivery timing (e.g., vaginal vs. cesarean) .
- Non-Stress Tests (NST): Evaluates fetal well-being in high-risk pregnancies by analyzing heart rate responses to movement.
- Multi-Fetal Pregnancies: Compatible with twin and triplet monitoring, though additional probes may be required .
- Safety and Maintenance
- Alarm Systems: Generates alerts for abnormal FHR patterns (e.g., bradycardia, tachycardia) and signal loss. In the FM50 incident, alarms were triggered but overlooked due to user error .
- Probe Maintenance: Reusable transducers require regular calibration and cleaning to prevent cross-contamination.
- Training Requirements: Proper training is essential to avoid misapplication, as highlighted in the FDA adverse event report where incorrect transducer use contributed to a fetal death .
- Comparison with Similar Probes
- eFM-60 Bluetooth Probe: Competitors like Luckcome’s eFM-60 offer wireless monitoring and cloud data storage but lack Phiips’ Smart Pulse technology .
- Legacy Models: The FM20/30 series predates the FM50 but shares core functionalities, such as TOCO and ultrasound integration
