[0001] The present application relates to a blood pressure measuring device, in particular to a blood pressure measuring device capable of measuring meridian pulse. BACKGROUND

[0002] Blood pressure meter is an important medical device in people's life, which can accurately measure blood pressure such as systolic pressure and diastolic pressure. However, in the existing technology, the function of blood pressure meter is single and changeless, and other data in human blood flow cannot be converted into effective information that can provide doctors to judge the body condition, and the application range is limited to the function of general blood pressure measurement.

The signal sensing unit is attached to the surface of the gas bag unit. The pressure sensing unit is coupled to the space.
