Clinical Trial of H2-BP Electronic Sphygmomanometer

"The patient will have the test device applied to one wrist to measure blood pressure and the control device applied to the upper arm of the same arm to measure blood pressure.~1. H2-BP: The test device is placed on the wrist and presses a button to start pressurising. When the measurement is complete, the systolic and diastolic blood pressure is displayed on the screen.~2. big ben® Sphygmomanometer: The cuff is placed on the upper arm and the pump is pressed manually to inflate. 2 measurers will measure systolic and diastolic blood pressure by connecting 2 stethoscopes separately to one cuff.~Due to the external nature of the study medical device, it is not possible to blind subjects and investigators, so that subjects and measurers are aware of the allocation. Therefore, blinding of subjects and measurers will not be used in this study."
