Fetal Dopplers and Monitors

Essential diagnostic and monitoring devices designed to assess fetal well-being, heart rate, and uterine activity during pregnancy and labor. This category includes handheld Doppler probes for intermittent heart rate detection, electronic fetal monitors (EFM) for continuous cardiotocography (CTG), tocodynamometers for measuring contractions, and telemetry systems for mobile monitoring. These non-invasive tools provide critical information on fetal health, helping to identify signs of distress, monitor labor progress, and support clinical decision-making for prenatal care and intrapartum management. Ideal for obstetrician offices, antenatal clinics, hospital labor and delivery wards, and maternity triage units.

Fetal & Maternal Monitor

A Fetal & Maternal Monitor is an electronic monitoring system that simultaneously records fetal heart rate (via external ultrasound or internal scalp electrode), uterine contractions (via external tocodynamometer or intrauterine pressure catheter), and maternal vital signs (blood pressure, heart rate, oxygen saturation). Used for antepartum and intrapartum fetal assessment, non-stress tests, contraction stress tests, and monitoring of high-risk pregnancies including gestational diabetes, hypertensive disorders, and multiple gestations. Features high-resolution display, continuous paper recording, alarm systems for fetal distress, and data storage for medical records. External monitoring is non-invasive for routine use; internal monitoring provides more accurate data but requires ruptured membranes and cervical dilation. Class II medical device requiring FDA clearance and qualified interpretation of fetal heart rate patterns. Essential for assessing fetal well-being and guiding obstetric interventions.

Fetoheart Sonic Aid Doppler (clinic/hospital use)

A Fetoheart Sonic Aid Doppler (Fetal Doppler) is a Class II medical ultrasound device (2-3 MHz probe) for real-time detection and audible/visual display of fetal heart rate in clinical obstetric settings from 10-12 weeks gestation. Features include handheld or tabletop console, waterproof probe, digital heart rate display (30-240 bpm), amplified speaker, headphone jack, and rechargeable battery or AC power operation. Continuous wave or pulsed wave Doppler technology with auto-correlation signal processing rejects maternal artifact. Primary clinical applications include fetal heart rate detection and monitoring during routine prenatal visits, confirmation of fetal viability in first trimester, intermittent fetal monitoring during labor, non-stress test administration, multiple gestation assessment, fetal presentation determination, and post-procedure confirmation (amniocentesis, CVS, ECV). Critical safety considerations include following ALARA principle (minimum necessary exposure), appropriate ultrasound gel use, probe pressure avoidance, infection control (probe cleaning between patients), differentiation of fetal from maternal signals, and interpretation by qualified providers. Essential equipment in outpatient obstetric clinics, hospital labor and delivery units, and prenatal care settings.

Fetoheart Sonic Aid Doppler (home use)

A Fetoheart Sonic Aid (Doppler) for Home Use is a consumer-grade, FDA-cleared handheld ultrasound device (2-3 MHz) that enables expectant parents to detect and listen to fetal heart sounds in the home environment from approximately 16 weeks gestation. Features include compact lightweight design (100-250g), simple controls, digital heart rate display (50-210 bpm), built-in speaker, headphone jack, and AA battery or USB rechargeable power. Continuous wave Doppler technology provides real-time audio of fetal heart sounds for maternal reassurance and bonding. Primary applications include maternal reassurance and emotional bonding between prenatal visits, confirmation of fetal activity, supplemental monitoring for high-risk pregnancies under provider guidance, and family involvement in the pregnancy experience. Critical safety information includes FDA-mandated labeling that device is for reassurance only (not medical diagnosis), optimal use after 16 weeks, limitation to 5–10-minute sessions, recognition that inability to detect heartbeat may not indicate a problem, and requirement to continue regular prenatal care. Not a substitute for professional medical evaluation; seek immediate care for bleeding, pain, fluid leakage, or decreased fetal movement.

Pinnard Fetoscope (plastic/metal)

A Pinnard Fetoscope (Pinard horn) is a mechanical acoustic horn (150-200 mm length, 40-60 mm bell) for auscultation of fetal heart sounds through the maternal abdomen, available in traditional metal (stainless steel/chrome-plated, 150-300g, autoclavable, durable, requires warming) and modern plastic (medical-grade polymer, 30-80g, lightweight, unbreakable, economical, not autoclavable) versions. The flared bell collects fetal heart sounds, concentrating them through the tapered horn to the single earpiece for mechanical amplification (10-20 dB). Primary clinical applications include intermittent fetal heart rate monitoring during prenatal care and labor in low-risk pregnancies, confirming fetal viability, determining fetal presentation and position through point of maximal intensity, monitoring multiple gestations, and providing non-interventive fetal assessment in natural childbirth, home birth, and resource-limited settings. Class I medical device. Requires significant practitioner training and experience; reliable after 18-20 weeks gestation; limited by maternal obesity, anterior placenta, and ambient noise. Critical safety considerations include infection control (metal autoclavable, plastic chemical disinfection only), gentle abdominal pressure, maternal positioning, and recognition that Pinnard is not a replacement for electronic monitoring in high-risk pregnancies.

Ultrasonic Doppler

An Ultrasonic Doppler is a handheld or tabletop medical device that uses continuous wave Doppler ultrasound (2-10 MHz probes) to detect and amplify blood flow sounds for fetal heart rate monitoring and peripheral vascular assessment. Available with obstetric probes (2-3 MHz for deep fetal detection) and vascular probes (4-5 MHz for deep vessels, 8-10 MHz for superficial vessels). Features audio output through speaker or headphones, digital heart rate display (30-300 bpm), and directional flow capability on select models. Primary clinical applications include fetal heart rate detection and monitoring (as early as 10-12 weeks gestation), peripheral arterial disease assessment (ankle-brachial index calculation), deep vein thrombosis evaluation, blood pressure measurement in difficult populations, intraoperative and postoperative vascular monitoring, wound healing assessment, and penile blood flow evaluation for erectile dysfunction. Class II medical device requiring FDA clearance. Critical safety considerations include following ALARA principle for ultrasound exposure, appropriate gel use, probe pressure avoidance, infection control (probe cleaning and sterile covers), and qualified interpretation of Doppler sounds.
