Intended Use

Fetal & Maternal Monitor (Model: F15A, F15A Air) is intended for providing Non-Stress testing or fetal monitoring for pregnant women from the 28th week of gestation. It is intended to be used only by trained and qualified personnel in antepartum examination rooms, labor and delivery rooms. Fetal & Maternal Monitor (Model: F15A, F15A Air) is intended for real time monitoring of fetal and maternal physiological parameters, including non-invasive monitoring and invasive monitoring: Non-invasive physiological parameters: • Maternal heart rates (MHR) • Maternal ECG (MECG) • Maternal temperature (TEMP) • Maternal oxygen saturation (SpO2) and pulse rates (PR) • Fetal heart rates (FHR) • Fetal movements (FM) • FTS-3 Note: SpO2 and PR are not available in F15A Air. Invasive physiological parameters: • Uterine activity • Direct ECG (DECG)

Device Story

F15A/F15A Air monitors fetal and maternal physiological parameters in real-time. Inputs include ultrasound signals (FHR), ECG leads (MECG, DECG), temperature probes, SpO2 sensors, and uterine activity sensors. Device processes signals via pulse Doppler with autocorrelation for FHR; displays, stores, and prints data; and transmits to central monitoring systems. Used by clinicians in antepartum/labor/delivery rooms. Output provides real-time vital signs and alarm notifications to assist clinical decision-making during pregnancy and labor. Benefits include continuous monitoring of fetal well-being and maternal status.

Clinical Evidence

Bench testing only. Performance validated through functional and system-level testing, electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), and specific parameter standards (e.g., IEC 60601-2-37 for ultrasound, ISO 80601-2-61 for oximetry). Software verification/validation and cybersecurity testing performed per FDA guidance.

Technological Characteristics

Multi-parameter monitor; AC/battery powered (Li-ion). Sensing: Pulse Doppler (1 MHz) for FHR, ECG electrodes, thermistor, SpO2 sensor, pressure transducer for IUP. Connectivity: Central monitoring system integration. Electrical safety: CF/CF-defibrillation-proof/BF-defibrillation-proof classifications. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-37, ISO 80601-2-61, ISO 80601-2-56.

Indications for Use

Indicated for pregnant women from 28th week of gestation requiring non-stress testing or fetal/maternal physiological monitoring. Used by trained personnel in antepartum, labor, and delivery settings.

Regulatory Classification

Identification

Dear Yue Tracy:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
