Validation of the Arm-Type Fully Automatic Blood Pressure Monitor DBP-62F4B-P in adolescents and adults according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (ISO 81060-2:2018+Amd 2:2024) standard.
TL;DR
The Arm-Type Fully Automatic Blood Pressure Monitor (model: DBP-62F4B-P) meets the accuracy and consistency requirements of the AAMI/ESH/ISO standard for SBP and DBP measurement in adolescents and adults with arm circumference 22.0-42.0 cm and is suitable for home use based on its design features and validation performance.
Abstract
Objective
To validate the accuracy and safety of the Arm-Type Fully Automatic Blood Pressure Monitor (model: DBP-62F4B-P) manufactured by JOYTECH Healthcare Co., Ltd. for blood pressure (BP) measurement in adolescents and adults with arm circumference 22.0-42.0 cm, in accordance with the Association for the Advancement of Medical Instrumentation (AAMI)/European Society of Hypertension (ESH)/International Organization for Standardization (ISO) (ISO 81060-2:2018+Amd 2:2024) international standard.
Methods
A total of 90 subjects were enrolled. Three valid datasets were collected from each subject, yielding 270 datasets for analysis. The mercury sphygmomanometer (reference device) data were used as the gold standard to evaluate whether the accuracy of the test device met the requirements.
Results
Based on 270 valid datasets, the mean difference between the test device and the reference device for SBP was -0.49 mmHg (SD = 7.29 mmHg), and for DBP was 1.45 mmHg (SD = 6.14 mmHg), meeting Criterion 1 requirements. Analysis based on individual averages of the 90 subjects showed a mean difference of -0.49 mmHg (SD = 5.57 mmHg) for SBP and 1.45 mmHg (SD = 5.05 mmHg) for DBP, both meeting the requirements of Criterion 2. The device maintained stable measurement performance across different arm circumferences, ages, and BP levels.
Conclusion
The Arm-Type Fully Automatic Blood Pressure Monitor (model: DBP-62F4B-P) meets the accuracy and consistency requirements of the AAMI/ESH/ISO (ISO 81060-2:2018+Amd 2:2024) standard for SBP and DBP measurement in adolescents and adults with arm circumference 22.0-42.0 cm. It can be safely and effectively used for BP monitoring in clinical settings and, by extension, is suitable for home use based on its design features and validation performance.
