Blood pressure data processing device, blood pressure data processing method, and blood pressure data processing program

Abstract

According to one embodiment of the present invention, a blood pressure data processing device includes a body movement index calculation unit, a body movement intensity determination unit, and a bloodpressure data processing unit. The body movement index calculation unit calculates a body movement index that is a statistical value, for a unit time period, for movement data obtained from a movement sensor that is mounted on a user or for pressure sensor data obtained from a pressure sensor array that is included in a blood pressure sensor. On the basis of the body movement index, the body movement intensity determination unit determines whether the intensity of the body movement of the user during the unit time period corresponds to a first level or a second level. If the body movement intensity is determined to be at the first level, the blood pressure data processing unit performs first data processing on blood pressure data obtained from the user during the unit time period. If thebody movement intensity is determined to be at the second level, the blood pressure data processing unit performs second data processing on the blood pressure data.

Description

technical field [0001] The present invention relates to the processing of blood pressure data. Background technique [0002] Patients with abnormal blood pressure (typically hypertension) expect daily blood pressure management. Conventional fixed blood pressure measuring devices are not suitable for portability, and measuring blood pressure outside the home, such as a workplace or a destination, places a heavy burden on the user. In addition, if blood pressure is measured only a few times a day, it is difficult to capture sudden blood pressure fluctuations that may pose a risk of developing cerebral or cardiovascular diseases. [0003] In recent years, with the development of sensor technology, for example, a user terminal capable of measuring a user's blood pressure by simply wearing it on the user's wrist has been realized. According to such a user terminal, it is possible to timely measure blood pressure without imposing a large burden on the user. Among such user term...

AI Technical Summary

Problems solved by technology

[0004] When the user has body movement, noise may be generated due to the influence of body movement, etc., and the measurement accuracy of blood pressure may decrease.

Especially in the case of continuous measurement of the user's blood pressure, the user may not always be in a quiet state, so it is possible to mix high-reliability blood pressure data and low-reliability blood pressure data

Therefore, when analyzing the blood pressure data, there is a possibility of ignoring or conversely erroneously detecting the occurrence of the above-mentioned sudden blood pressure fluctuation.
