生体状態モニタリングシステム、これを備えるベッドシステム、及び生体状態モニタリング方法

Japanese Patent JP7409987

B2

To provide an alternative system for monitoring a biological state of a subject by using a load detector.SOLUTION: A biological state monitoring system for monitoring a biological state of a subject on a bed includes: a first load detector provided on the bed or at the lower part of the leg of the bed on one side in a width direction of the bed for detecting a first load, which is a load by the subject, including a load component that vibrates in response to breathing of the subject and a load component that vibrates in response to a heart beat of the subject; a second load detector provided on the bed or at the lower part of the leg of the bed on the other side in the width direction of the bed for detecting a second load, which is a load by the subject, including a load component that vibrates in response to breathing of the subject and a load component that vibrates in response to a heart beat of the subject; a heart beat state determination unit for obtaining a difference between the first load and the second load, and determining a heart beat state of the subject from the difference; and a correction unit for correcting the difference so that the load component that vibrates in response to the breathing of the subject included in the difference becomes small on the basis of an inclination in a direction of a body axis of the subject with respect to a length direction of the bed.SELECTED DRAWING: Figure 1
