The BF-500D is a pocket fetal Doppler with integrated Bluetooth mobile app connectivity, manufactured by Shenzhen Bestman Instrument Co, Ltd in Shenzhen, China. The unit operates at a 2.0 MHz ultrasonic frequency with a tolerance of plus or minus 10 percent, producing an ultrasonic intensity of no more than 10 mW per square centimetre. Fetal heart rate (FHR) detection ranges from 60 to 210 beats per minute with a plus or minus 2 bpm accuracy, and the device triggers audible and visual alarms when FHR falls below 100 bpm or exceeds 160 bpm. The comprehensive sensitivity is rated at greater than or equal to 90 dB, and the Doppler frequency bandwidth spans 100 to 3000 Hz.
The BF-500D features a blue backlight LCD for low-light operation, displaying FHR, synchronous FHR signal, battery indicator, sound volume, and alarm status. A built-in rechargeable 8.4V Ni-MH battery powers the unit for more than five hours of continuous use, with an optional 9V dry battery alternative. The device includes automatic power-off after one minute of inactivity, self-detect function, low-battery alarm, and automatic dormancy. The 2.0 MHz probe is the standard configuration, and the unit weighs 270 grams with a gallus for portable carrying. Single unit dimensions are 24 by 23 by 12 centimetres with a gross weight of 1.5 kilogrammes; master carton holds 20 units measuring 44 by 36 by 42 centimetres and weighing 18 kilogrammes gross.
Intended users include obstetric clinics, midwifery practices, hospital maternity wards, and mobile health programmes. The CE marking indicates conformity with the EN61266:1995 executive standard for fetal Doppler devices. Buyers should confirm current CE marking validity under the Medical Device Regulation (EU) 2017/745, as the cited standard dates to 1995. The mobile app compatibility details, including iOS and Android version support and Bluetooth protocol version, are not specified in the source and require direct supplier confirmation. The standard accessory pack includes charger, earphone, gel, small bag, gallus, and operation manual.

Before ordering the BF-500D from Shenzhen Bestman Instrument Co, Ltd, buyers should verify that the CE marking is current under the Medical Device Regulation (EU) 2017/745 and that the EN61266:1995 standard remains valid for the declared device classification. Request the complete technical file, risk management documentation per ISO 14971, and clinical evaluation report. Confirm whether the supplier holds ISO 13485 certification for medical device quality management, as this is not stated in the source data. For markets requiring FDA clearance, verify 510(k) submission status or predicate device equivalence.
Logistics and trade terms must be confirmed directly with the supplier, as no Incoterms, lead times, or port details are specified. Shenzhen offers multiple export channels including Shenzhen Port and Hong Kong transshipment. Buyers should clarify whether the stated address represents the manufacturing facility or a trading office, and arrange pre-shipment factory audit or third-party inspection. Payment terms, including letter of credit, advance payment percentage, and escrow options, require written confirmation. Consider product liability insurance given the medical device classification and target market regulatory requirements.
Quality assurance should include incoming inspection of Doppler frequency accuracy using a calibrated phantom or string target at known motion speeds, verification of alarm thresholds at 100 bpm and 160 bpm boundaries, and battery cycle testing under continuous operation. Test the mobile app on your target operating system versions before bulk commitment. Request batch calibration certificates and traceability records for the ultrasonic transducer element. For documentation, ensure the supplied operation manual includes the local language of your market and that labelling meets destination country requirements. Store units within the stated 10-40 degrees Celsius and ≤80 percent humidity range, and verify gel expiry dates upon receipt.
