Blood pressure measurement apparatus, portable pressure measurement apparatus, and calibration method for blood pressure measurement apparatus

Abstract

A blood pressure measurement apparatus, a portable pressure measurement apparatus, and a calibration method for the blood pressure measurement apparatus are provided. The blood pressure measurement apparatus includes a pulse wave measurer configured to measure pulse wave data of a subject while a user pressurizes and depressurizes the blood pressure measurement apparatus, using a portable pressure measurement apparatus, and a communicator configured to receive pressure data that is applied to the blood pressure measurement apparatus during the pressurizing and the depressurizing of the blood pressure measurement apparatus, from the portable pressure measurement apparatus, the pressure data being measured by the portable pressure measurement apparatus. The blood pressure measurement apparatus further includes a processor configured to update a blood pressure estimation formula, based on the received pressure data and the measured pulse wave data.

What is claimed is: 
     
         1 . A blood pressure measurement apparatus comprising:
 a pulse wave measurer configured to measure pulse wave data of a subject while a user changes pressure on a force touch panel;   a pressure measurer comprising the force touch panel, and configured to measure pressure data that is applied to the blood pressure measurement apparatus during the changing pressure on the force touch panel; and   a processor configured to update a blood pressure estimation formula, based on the measured pressure data and the measured pulse wave data.   
     
     
         2 . The blood pressure measurement apparatus of  claim 1 , wherein the pressure measurer is further configured to:
 sense a touch area of the force touch panel that the user touches, and a force that the user applies on the force touch panel; and   determine the pressure data that is applied to the blood pressure measurement apparatus, based on the sensed touch area and the sensed force.   
     
     
         3 . The blood pressure measurement apparatus of  claim 1 , wherein the processor is further configured to:
 estimate a reference blood pressure value by performing an oscillometric method, based on the measured pressure data and the measured pulse wave data; and   update the blood pressure estimation formula, based on the estimated reference blood pressure value.   
     
     
         4 . The blood pressure measurement apparatus of  claim 1 , wherein the processor is further configured to provide calibration guide information of a method of calibration, using the force touch panel. 
     
     
         5 . The blood pressure measurement apparatus of  claim 4 , wherein the calibration guide information comprises information of a method of the changing pressure on the force touch panel. 
     
     
         6 . The blood pressure measurement apparatus of  claim 1 , wherein the blood pressure measurement apparatus is a wrist wearable device.
