Blood pressure measurement device for measuring at appropriate timing
First Claim
1. A blood pressure measurement device comprising:
- a sphygmomanometer that measures a blood pressure of a subject;
a sensor that detects physiological information on a type excluding the blood pressure of the subject; and
a processor that determines a start of blood pressure measurement in the sphygmomanometer that counts a predetermined time, based on an end of a blood pressure measurement, that limits the start of the blood pressure measurement based on the physiological information, and that outputs a control signal for activating the sphygmomanometer,wherein the processor determines a first condition, determines to start the blood pressure measurement when a value obtained from the physiological information satisfies the first condition during a period outside the predetermined time, and determines to start counting the predetermined time from the end of the blood pressure measurement,wherein the processor determines not to start the blood pressure measurement during the predetermined time, if the value obtained from the physiological information satisfies the first condition,wherein the processor determines a second condition, determines to start the blood pressure measurement when the value obtained from the physiological information satisfies the second condition during the predetermined time,wherein the second condition is more critically severe than the first condition, and the physiological information of the second condition is of a same type as that of the first condition, andwherein the processor determines not to start the blood pressure measurement during the predetermined time unless the second condition that is more critically severe than the first condition is satisfied.

Abstract
A blood pressure measurement device includes a finger cuff for measuring a blood oxygen saturation level of a subject as physiological information excluding a blood pressure, a pulse wave detecting portion, and an oxygen saturation level calculating portion, where a start of blood pressure measurement in a sphygmomanometer is determined by a comparing and determining portion when a value becomes greater than or equal to a reference value. After the end of the measurement, a time limit for limiting the start of the blood pressure measurement is set. The comparing and determining portion determines not to start the blood pressure measurement within the time limit even if the blood oxygen saturation level becomes greater than or equal to the reference value.

7. A blood pressure measurement device comprising:
-
a sphygmomanometer that measures a blood pressure of a subject; a sensor that detects physiological information on a type excluding the blood pressure of the subject; and a processor that determines a first condition when the physiological information enters a first severe level, that determines a start of blood pressure measurement in the sphygmomanometer, and that starts a counting of a predetermined time, during which the start of the blood pressure measurement is limited such that; when the predetermined time counting has not started and when the first condition is detected, the blood pressure measurement starts and, after the blood pressure measurement is completed, the counting of the predetermined time starts; and during the counting of the predetermined time, the blood pressure measurement is limited from being started when the first condition is detected, wherein the processor further determines a second condition when the physiological information enters a second severe level, and determines to start the blood pressure measurement when the second condition is detected during the predetermined time, wherein the second severe level is at a different level than the first severe level, and the physiological information of the second severe level is of a same type as that of the first severe level, and wherein the processor determines to limit the start of the blood pressure measurement during the predetermined time unless the second condition, which is associated with the second severe level at the different level than the first severe level associated with the first condition, is satisfied.
