Intended Use

This oscillometric blood pressure monitor is intended to measure the systolic and diastolic blood pressure, pulse rate and mean arterial pressure (MAP) in people aged 3 years or older. This device is intended to be operated by trained personnels only. Examples of trained operators include professional clinical and healthcare personnels.

Device Story

Battery-driven, automatic non-invasive blood pressure monitor; uses oscillometric technique to measure systolic/diastolic blood pressure, pulse rate, and mean arterial pressure (MAP). Input: pressure oscillations detected via inflatable upper arm cuff (three sizes: 14-22cm, 22-32cm, 32-52cm). Operation: device automatically inflates cuff, processes pressure signals, and displays results. Used in medical facilities by trained clinical/healthcare personnel. Output: digital display of BP and pulse metrics. Clinical decision-making: provides objective hemodynamic data for patient assessment and monitoring.

Clinical Evidence

Clinical study performed on the predicate device (WatchBP, K101275) using the same-arm sequential method per ISO 81060-2:2013. Study included 159 subjects: 85 adults (54±19 years), 33 adults (53±17 years), and 41 children (7.7±2.8 years). Results met ISO 81060 acceptance criteria for accuracy across all three cuff sizes (14-22cm, 22-32cm, 32-52cm).

Technological Characteristics

Battery-powered oscillometric sphygmomanometer. Materials: Nylon cuff. Standards: IEC 60601-1 (safety), IEC 60601-1-2 (EMC), IEC 80601-2-30 (performance). Dimensions: 170mm x 135mm x 41mm. Weight: 510g. Software level of concern: Moderate.

Indications for Use

Indicated for measuring systolic/diastolic blood pressure, pulse rate, and MAP in patients aged 3 years or older. Intended for use by trained clinical/healthcare personnel in medical facilities.

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.

- 7. Clinical Test Conclusion
The blood pressure model for proposed device is identical to the device WatchBP cleared in K101275. Therefore, a new clinical study was not conducted on the proposed device and a study performed on WatchBP per ISO 81060-2:2013 is provided to demonstrate the accuracy of the professional oscillometric blood pressure monitor in adults and children, the clinical study result is summarized in following.

Three 85 subjects (aged 54±19 years), 33 subjects (aged 53±17 years ) and 41 children (7.7±2.8 years) were respectively recruited to fulfil the age, sex, BP and cuff distribution criteria of the ISO standard using the same-arm sequential BP measurement method. Three cuffs were tested in this clinical study to cover all proposed cuff models (small for arm circumference 14-22 cm, medium for 22-32cm and large cuff for 32-52cm). The test results can meet the requirements of acceptance criteria and ISO 81060. Therefore, the clinical accuracy of proposed device used on adult and children can be demonstrated.
