Voice blood pressure measuring instrument, medical-grade precise upper arm electronic blood pressure monitor, home fully automatic blood pressure meter

Cuff sphygmomanometer measurement: The cuff sphygmomanometer is the most common tool for measuring blood pressure and is usually used in the upper arm. During measurement, the cuff is inflated to block the arterial blood flow, and then slowly deflated. Systolic and diastolic blood pressures are recorded through a stethoscope or sensor. This method is highly accurate and suitable for the majority of people, but it requires correct operation to ensure the accuracy of the results. Cuff blood pressure monitors are classified into mercury column type, pneumatic type and electronic type. Among them, the mercury column type is considered the most accurate, but it has gradually been phased out due to environmental protection reasons. Pneumatic and electronic types are more convenient and suitable for household use.
