SPHYGMOMANOMETER AND BLOOD PRESSURE MEASURING METHOD USING SAME

Document Type and Number:

WIPO Patent Application WO/2019/103424

Kind Code:

A1

Abstract:

Disclosed are an optical measurement type sphygmomanometer and a blood pressure measuring method. The sphygmomanometer according to one aspect of the present invention comprises: a pulse wave measuring unit for measuring arterial pulse waves; a blood pressure difference calculating unit for calculating the difference between blood pressure values caused by a height difference between two certain points at which the pulse waves are measured; and a blood pressure wave calculating unit for converting the pulse waves measured at the two points into blood pressure waves by using the difference between blood pressure values. The sphygmomanometer according to one aspect of the present invention can be provided as a wearable sphygmomanometer, that is, a portable wrist sphygmomanometer or a finger sphygmomanometer that can be worn on a predetermined part of the human body, such as the wrist or the finger. In addition, the present invention can be a sphygmomanometer for measuring blood pressure by allowing the finger to make contact with an optical measuring sensor of a smart phone. The present invention enables the sphygmomanometer for measuring blood pressure by using pulse waves to reflect, in a blood pressure calculation, rapid changes in a blood vessel state which largely influence a blood pressure measurement in addition to a blood flow rate, thereby enabling blood pressure to be measured with improved accuracy.
