Intended Use

The device is a digital monitor intended for use in measuring blood pressure and pulse rate in adult patient population with wrist circumference ranging from 13.5cm to 21.5cm in home and hospital facilities by using a non-invasive oscillometric technique. The device detects the appearance of irregular heartbeats during measurement and gives a warning signal with readings.

Device Story

Digital wrist blood pressure monitor; uses oscillometric method to measure systolic/diastolic blood pressure and pulse rate. Input: pressure sensor detects cuff oscillations; microprocessor transforms signals into BP/pulse values. Output: LCD displays readings and irregular heartbeat (IHB) warning. Used in home/hospital by patients or clinicians. IHB detection compares pulse wave time intervals to mean; triggers warning if difference exceeds range. Benefits: non-invasive, automated monitoring of cardiovascular metrics.

Clinical Evidence

Clinical validation per ISO 81060-2:2018. Study included 85 subjects (41 male, 44 female). Comparison against manual mercury sphygmomanometer using same-arm sequential method. Results confirmed accuracy within acceptable scope specified in ISO 81060-2. No adverse events reported.

Technological Characteristics

Oscillometric measurement via piezo-resistive pressure sensor. Components: microprocessor, pump, electromagnetic deflation valve, LCD. Power: 2x AAA batteries or adapter. Materials: ABS housing, PU shell cuff. Standards: ISO 10993 (biocompatibility), IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, IEC 80601-2-30.

Indications for Use

Indicated for adult patients (age 12+) with wrist circumference 13.5cm–21.5cm requiring non-invasive blood pressure and pulse rate measurement in home or hospital settings. Includes irregular heartbeat detection.

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.

### 4 Device Descriptions

Weony Digital Blood Pressure Monitor WBP Series are designed to measure the systolic and diastolic blood pressure and pulse rate of an individual (at least 12 or above) by using a non-invasive technique in which an inflatable cuff is wrapped around the wrist. Our method to define systolic and diastolic pressure is similar to the auscultatory method but uses an electronic pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alterations in cuff pressure to electrical signals, by analyzing those signals to define the systolic and diastolic blood pressure and calculating pulse rate, which is a well-known technique in the market called the "oscillometric method".

The main components of the Blood Pressure Monitor are the main unit and cuff unit. ABS is used to outer housing of the main unit. The preformed cuff unit, which is applicable to wrist circumference approximately between 135 and 215 mm, includes the inflatable bladder and PU shell. All models of the wrist blood pressure monitor use a single size of cuff. The device consists of the microprocessor, the pressure sensor, the operation keys, the pump, the electromagnetic deflation control valve, and the LCD. The subject devices are powered by two AAA alkaline batteries or adatpter.

The device has irregular heart beat (IHB) indicator which compares the longest and the shortest time intervals of detected pulse waves to mean time interval and displays a warning signal with the reading to indicate the detection of irregular pulse rhythm when the difference of the time intervals is over a specified range.

#### 5 Intended Use/ Indications for Use

The device is a digital monitor intended for use in measuring blood pressure and pulse rate in adult patient population with wrist circumference ranging from 13.5cm to 21.5cm in home and hospital facilities by using a non-invasive oscillometric technique. The device detects the appearance of irregular heartbeats during measurement and gives a warning signal with readings.
