Intended Use

BW-BA1 Bluetooth Blood Pressure Monitor is intended to be used to measure systolic and diastolic blood pressure and heart rate from the upper arm with arm circumference ranging from 8.7 inches (approx.22 cm to 42 cm) using the oscillometric method. The device detects the appearance of irregular heartbeats during measurement and gives a "IHB" warning signal with readings. The intended patient population of the device is only adult population aged 18 or older at home, not applied to the other populations such as neonatal baby. It cannot be used while the arm has bleeding or wound to avoid the blood flowing from the wound in pressurizing. The device cannot be used by pregnant patients or patients suffering from pre-eclampsia.

Device Story

BW-BA1 is a non-invasive, oscillometric blood pressure monitor for home use. It consists of an upper-arm cuff and an electronic unit (no display) that connects via Bluetooth 4.0 to a collateral mobile device (iPhone/iPad) running a specific app. The device uses an electric pump to inflate the cuff; a semiconductor pressure sensor captures oscillometric signals during inflation. The system calculates systolic/diastolic blood pressure and heart rate, and identifies irregular heartbeats (IHB) defined as rhythm variations >25% from the average. Results are classified per WHO guidelines and displayed on the mobile app. The device is operated by the patient; the app provides the user interface for viewing measurements and tracking data. The system benefits patients by enabling convenient, remote-capable blood pressure monitoring and irregular heartbeat detection.

Clinical Evidence

Clinical validation was performed in compliance with ISO 81060-2. The study confirmed that the BW-BA1's blood pressure measurement performance is identical to the predicate device. The addition of the IHB function was evaluated and determined not to raise new safety or effectiveness concerns.

Technological Characteristics

Oscillometric measurement via semiconductor pressure sensor; electric pump inflation. Powered by rechargeable Li-ion battery. Connectivity: Bluetooth 4.0 to mobile devices (iPhone/iPad). Materials: Standard medical-grade cuff materials. Standards: IEC 60601-1, IEC 60601-1-11, IEC 80601-2-30, ISO 10993-1, ISO 10993-5, ISO 10993-10, IEC 62366-1.

Indications for Use

Indicated for adult patients aged 18+ for home-use measurement of systolic/diastolic blood pressure and heart rate via upper arm cuff (22-42 cm circumference). Contraindicated for neonates, pregnant patients, patients with pre-eclampsia, or individuals with arm wounds/bleeding.

Regulatory Classification

Identification

A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body.
