In other words, the blood pressure value measured by the wrist blood pressure measuring device is more likely to be affected by altitude
[0005] However, there is a height difference between the position of the blood pressure measurement device and the position of the heart when the posture is sitting or supine
Therefore, even if the measurement posture is judged under the same judgment conditions in the sitting posture and the supine posture, it is not suitable for judging whether it is the correct measurement position.

[0029] A blood pressure measurement device according to one embodiment of the present invention will be described. figure 1 It is a block diagram showing a configuration example of a blood pressure measurement device including a measurement posture determination unit. In this embodiment, a wrist-type blood pressure measurement device worn on a wrist as a wearing target site is described as an example. Of course, the wearing target site is not limited to the wrist, but may be the upper arm, and the same applies as long as it is an integrated upper arm blood pressure measurement device.

Even when the measurement posture for seated and supine positions is determined on the basis of the same condition, it is inappropriate to determine whether the measurement position is correct or not.This blood pressure measurement device measures the blood pressure in seated and supine positions by determining, when a night (sleeping) blood pressure measurement mode is set, the measurement posture using a measurement posture determination unit, taking into account the height difference between the position of the blood pressure measurement device in the supine position and the position of the heart of a subject, and obtaining a blood pressure measurement.
Description
technical field [0001] The present invention relates to a blood pressure measurement device and a blood pressure measurement method that detect a measurement posture of a subject and perform blood pressure measurement corresponding to the measurement posture. Background technique [0002] It is generally considered that the measured blood pressure value approximates the blood pressure value in the heart by installing the blood pressure measurement device at the same height as the heart of the subject during blood pressure measurement. For example, it is confirmed in Japanese Patent Laid-Open Publication No. 2007-54648 that the blood pressure value is affected by gravity, and measurement errors can be reduced by measuring at a height close to the heart position. Therefore, an upper arm blood pressure measurement device that wraps a cuff around an upper arm usually performs measurement with the elbow of the arm bent and placed on a table. [0003] In addition, as a blood pres...
