Blood pressure monitors determine blood pressure values by precisely capturing pressure oscillations within the cuff, and their accuracy is highly dependent on the micro-voltage stability of the pressure sensor. To address the reverse induced current generated during the charging and discharging of the internal micro-pump, and the power ripple caused by the inflation valve's operation, we offer a high-efficiency surge absorption and low-noise linear voltage regulation protection solution. These components effectively eliminate interference from the power source on the analog sampling circuit, ensuring that the linear acquisition of the pressure signal is unaffected by fluctuations, thereby providing users with highly consistent and repeatable medical-grade measurement data.
