Electronic sphygmomanometer and blood pressure measurement method

摘要

An electronic sphygmomanometer includes a cuff to be attached to a blood pressure measurement site, a pump and a valve for adjusting a pressure to apply on the cuff, a pressure sensor for detecting the pressure of the cuff, a central processing unit (CPU) for calculating a blood pressure value from the cuff pressure, a memory for recording the blood pressure value, and an operation unit for performing a blood pressure measurement. Further, the CPU acquires information on an application voltage of the valve or the pump at a time of blood pressure measurement, and the information on the application voltage is stored in the memory. The CPU corrects the application voltage so that control of the valve or the pump is carried out based on the application voltage stored in the memory.

主权项

1. An electronic sphygmomanometer comprising:
a cuff to be attached to a measurement site for measuring a blood pressure; a pump and a valve that adjust a pressure to apply on the cuff; a pressure sensor that detects the pressure of the cuff; a blood pressure calculator that calculates a blood pressure value from the cuff pressure; a memory that records the blood pressure value; an operation unit that is configured to carry out a blood pressure measurement; a body fat meter that measures a quality of the measurement site; an input device configured to input user information related to the quality of the measurement site,
wherein the quality of the measurement site is a value indicative of a stiffness of an entire volume-area of an arm under the cuff; an information acquiring device that acquires information on an application voltage of either one of the valve or the pump at a time of blood pressure measurement,
wherein the memory stores the information on the application voltage of the one of the valve or the pump at the time of blood pressure measurement in association with the user information when the information on the application voltage of the one of the valve or the pump at the time of blood pressure measurement is acquired by the information acquiring device; and a corrector that corrects the application voltage of the one of the valve or the pump based on the user information so that control of the one of the valve or the pump is carried out based on the application voltage in a case where the application voltage associated with the user information is stored in the memory when calculating the blood pressure with the blood pressure calculator.
