Problems solved by technology

That is, there is no concept of specifying the change area of ​​the physiological information unique to the subject, and the blood pressure monitor is activated only based on the temporal change of the physiological information, so the blood pressure in the maximum area, the central area, and the minimum area of ​​the medically important physiological information cannot be captured. value

Embodiment Construction

[0065] (implementation form 1)

[0066] In the first embodiment, the medically necessary blood pressure measurement start timing is obtained from the change in the pulse rate which is one type of continuous physiological information other than the blood pressure. Here, it is based on the pulse rate, but it can be replaced by the heart rate corresponding to the same physiological phenomenon. An electrocardiogram is additionally required when using the heartbeat rate.

[0067] Using the pulse rate or the heart rate as an index for measuring the blood pressure measurement start timing has the following meanings. That is, pulse rate or heart rate is an indicator of the level of activity of the sympathetic nervous system, an increase of which correlates with the risk of cardiovascular events. Since the sympathetic nervous system also fluctuates when the pulse rate or the heartbeat rate fluctuates, by specifically measuring the blood pressure level at that time, a new blood pressu...

Abstract

A blood pressure measurement apparatus (1) includes a blood pressure monitor (8) measuring a subject's blood pressure, a finger cuff (6), a pulse wave detector (13) and a pulse rate calculator (14) operative to continuously measure a pulse rate serving as physiological information other than blood pressure, a pulse rate storage (12) storing the continuously measured pulse rate, and a comparator and determiner (15) determining from a previous, continuous pulse rate stored in the pulse rate storage (12) that a currently measured pulse rate is close to a specified level relative to a range in variation of a pulse rate unique to the subject. When the comparator and determiner (15) determines that the currently measured pulse rate corresponds to the specified level, the blood pressure monitor (8) is instructed to start blood pressure measurement.

Description

technical field [0001] The present invention relates to a blood pressure measurement device and method, and more particularly to a blood pressure measurement device and method for determining timing of blood pressure measurement based on changes in physiological information other than blood pressure. Background technique [0002] In recent years, according to studies using a portable 24-hour sphygmomanometer (hereinafter referred to as ABPM (Ambulatory Blood Pressure Monitoring), it has become clear that in addition to daytime blood pressure, nighttime blood pressure is also important for the prediction of cardiovascular risk and the treatment of hypertension. Specifically, it is considered to accurately estimate the individual's vascular risk by obtaining blood pressure information indicating the blood pressure value at the time when the physiological state changes during sleep, and to perform blood pressure management therapy. [0003] ABPM has the following characteristic...
