Description

  The present invention relates to a biological signal monitoring system that collects biological signals.

In recent years, a small number of portable terminal devices (hereinafter referred to as “wearable devices”) that are worn on a human body or the like are increasing. As a wearable device, for example, a device that converts a weak biological signal such as an electrocardiogram, a heartbeat, a myoelectricity, and a respiratory wave detected by a built-in sensor into an electric signal and transmits the signal wirelessly is known.
In such a wearable device for continuous monitoring, it is important to reduce the size and weight of the device so that it can be easily attached and detached from the human body.

  Therefore, conventionally, among such wearable devices, particularly in devices that detect electrical signals based on physiological information such as RR intervals, CVRR, RR50, etc., similar to electrocardiograms and heart rate variability (HRV). In many cases, a device having an input terminal to which two or more electrodes are connected is used. The RR interval is the interval between the R wave and the next R wave in the electrocardiogram. The CVRR is 100 for a certain period or a certain number of RR intervals divided by the average value. RR50 is the ratio of the difference between adjacent RR intervals of 50 milliseconds or more for a certain period or a certain number of RR intervals.

  For example, Non-Patent Document 1 discloses a biological signal monitor system having a plurality of electrodes and a plurality of input terminals. In the biological signal monitoring system disclosed in Non-Patent Document 1, for example, as shown in FIG. 5, the biological signal detected by the electrodes 101, 102, 103, 104 attached to the clothing 200 is monitored through the wiring 105. 106, the signal is processed and displayed and transmitted.

Yoo J., et al., “A Wearable ECG Acquisition System With Compact Planar-Fashionable Circuit Board-Based Shirt”, IEEE TRANSACTIONS ON INFORMATION TECHNOLOGY IN BIOMEDICINE, VOL.13, NO.6, pp.897-902, NOVEMBER 2009

  However, in the case of having a plurality of structurally identical electrodes such as P-FCB (Planar-Fashionable Circuit Board) disclosed in Non-Patent Document 1, if the monitor device is attached without paying attention to the mounting position, the plurality May be connected to a terminal different from the correct input terminal of the monitor device. As a result, there is a possibility that a biological signal to be acquired cannot be detected correctly.

  In the acquisition of physiological information of living organisms, the heart rate measurement that is widely used at present is mainly required to convert the interval of the maximum amplitude wave called the R wave of the electrocardiogram waveform into a numerical value (heart rate). Depending on the accuracy of the heart rate, there may be no significant effect even if the signals reaching the monitor device from the two left and right electrodes sandwiching the heart are reversed.

  However, in a system that uses HRV that requires high-precision data, such as CVRR, as physiological information of a living body, or a system that uses an electrocardiogram as physiological information, a signal acquired from a specific place on the living body is monitored. It was difficult to say that the structure was considered enough to input correctly to the input terminal of the device. If there are up to two terminals, correction by means of polarity inversion determination or the like can be considered, but in particular, the difference in input terminals with completely different properties such as a GND terminal in three or more terminals prevents normal operation of the apparatus. Could be the cause.
