Description

The present invention relates to a biological information measuring device.

BACKGROUND ART Biological information measuring devices that measure biological information are known.
When measuring cardiac magnetic fields (magnetocardia), which is an example of biological information measurement, it is necessary to align the person being measured and the measuring device so that the heart of the person being measured is placed near the center of the magnetic sensor array. There is. In magnetocardial measurement, it is important that the person being measured maintains the same posture during the measurement.
Further, as in magnetocardial measurement, in the measurement of other biological information, it may be important for the person to be measured to maintain the same posture during the measurement.

In the biomagnetism measuring device described in Patent Document 1, biomagnetism is measured simultaneously using a plurality of magnetic sensors (see Patent Document 1). In the biomagnetism measurement device, the plurality of magnetic sensors are held in a holding part so that their measurement directions are different, and the plurality of magnetic sensors are arranged in the holding part so that biomagnetism at multiple locations can be measured simultaneously. There is.

However, with conventional biological information measuring devices, it is sometimes difficult for a person to be measured to maintain the same posture while measuring biological information. For example, it is not easy for a person to be measured who is not accustomed to measurement to maintain the same posture.

As a specific example, when magnetocardial measurement is performed with the person being measured in a standing or sitting position, if the measurement is performed with the person being measured in a position where the back is not straight, the chest of the person being measured and the magnetocardiogram sensor The amplitude of the signal that is the measurement result of the magnetocardial sensor decreases due to distance between Problems such as a decrease in the quality of the resulting data may occur.

In addition, as a specific example, if anatomical information such as a chest X-ray is acquired immediately before magnetocardial measurement, and the results are superimposed on the magnetocardiographic measurement results, when the anatomical information is acquired, If there is a difference between the body position and the body position at the time of magnetocardiographic measurement, a shift may occur in the superposition.

The present invention was made in consideration of such circumstances, and an object thereof is to provide a biological information measuring device that can support a person to be measured to maintain the same posture while measuring biological information. shall be.
