Blood Pressure Monitor PCB Assembly--STHL

Blood pressure monitor PCBs serve as the core control unit, precisely regulating the step-by-step inflation and deflation of the cuff to match human physiological characteristics, while real-time processing of high-precision signals from pressure sensors and piezoelectric microphones that capture arterial pulse waves. Equipped with advanced adaptive algorithms, these boards filter out motion interference and environmental noise to accurately calculate systolic and diastolic blood pressure values with clinical-grade precision. Our customized PCBA solutions prioritize the stability of pressure sensing circuits, enhance the anti-interference performance of display and wireless data transmission modules, and fully support the seamless integration of both arm and wrist-type monitors for home and clinical use.
