Description

  The present invention is for a bioelectric signal monitor equipped with means for improving and stabilizing the quality of a received biosignal by bringing a bioelectrode for measuring a biosignal attached to a garment into close contact with the surface of the living body. Regarding clothing.

  Due to the recent miniaturization of wireless electronic devices and the advancement of network infrastructure, a health cloud service linked to the cloud constantly monitoring vital data such as heart rate, electrocardiogram, body temperature, body motion, pulse wave, blood pressure, etc. It is being realized. In these systems, the signal quality received by the sensor that is the entrance of data is one of the important items. In particular, clothing with a biological electrode attached is considered promising as a method for always wearing a sensor (for example, see Non-Patent Document 1).

C. Park, PH Chou, Y. Bai, R. Matthews, and A. Hibbs, "An ultra-wearable, wireless, low power ECG monitoring system," in Proc. IEEE Biomedical Circuit System Conf., London, UK, Nov 2006, pp.241-244

  However, in the case of clothes of a predetermined size (underwear such as shirts and pants), if the electrode for receiving biological signals is attached to the inside of the clothes, it is necessary to acquire biological signals due to human body movement, posture, or physique There was a problem that a good adhesion could not be obtained.

  As shown in FIG. 17, the received signal quality of a human or animal biological signal is determined by how deterioration due to an increase in impedance of each part can be suppressed. In particular, it is considered that the impedance between (102 to 104) between the skin and the bioelectrode indicated by the double-ended arrow in FIG. Here, the degree of contact defined at the interface between the skin and the bioelectrode is expressed by an index called “effective contact area”.

  The interface between the two objects A and B having irregularities can be expressed as shown in FIG. When the interface portion between the objects A and B is deformed, as shown in FIGS. 19A and 19B, the contact is smaller when the contact pressure is smaller than when the contact pressure is larger (a) than when the contact pressure is larger (a). Since the cross-sectional area S2 decreases compared to S1 (S1> S2) and the gap increases (L1 <L2), it is considered that the impedance increases regardless of whether it is a resistance component or a capacitance component. The same applies when the gap is filled with liquid as indicated by lq1 and lq2.

  Here, the “effective contact area” can be measured by measuring the impedance value when a sine wave signal is applied between the objects A and B. When the contact pressure decreases due to body movement or size mismatch, the state shifts from (a) to (b) shown in FIG. 19 and the “effective contact area” decreases, resulting in an increase in impedance. As a result, the quality of the received biological signal varies and deteriorates.

  FIG. 20 is a diagram illustrating a contact state between a living body electrode and a human body when a biological electrical signal monitoring garment including the living body electrode is worn. The bioelectric signal monitoring garment of FIG. 20A is a garment (10), a biosignal measuring device (11) for measuring a biosignal such as an electrocardiograph / heart rate monitor, bioelectrodes (12), (13), wiring (14) and (15). As shown in FIG. 20 (b), it is ideal that the bioelectrode is in close contact with the human body (100). However, when the contact pressure when the bioelectrode contacts the human body is insufficient, the bioelectrode shown in FIG. ), The degree of adhesion decreases due to gaps (106, 107) generated between the bioelectrode and the human body.

  On the other hand, if the gaps (106) and (107) between the bioelectrode and the human body are eliminated, and clothing with a small size is used to improve the degree of adhesion, or clothing that compresses the entire human body is used. However, there is a problem in that the wearing load increases due to discomfort generated in the human body, making it difficult to monitor a biological signal for a long time.

  In order to solve the above problems, a bioelectrical signal monitoring garment according to the present invention is installed in a garment and a predetermined position of the garment, and when the garment is put on the living body, the bioelectric signal of the living body And the garment is provided with a stretchable fabric in an area including at least the location where the electrode is installed, and the stretched fabric has a stretched peripheral portion of the location where the electrode is installed. And an adhesion means for fixing the electrode to the living body.

  The contact means may include a plurality of engaging members that are provided on a surface of the stretchable fabric and that can be engaged with each other.

  The contact means is provided in at least a part of the periphery of the stretchable fabric, a tightening member that tightens the living body from the periphery of the clothes, and a fixing member that fixes the tightening member to a predetermined length. You may have.

  The contact means may include a pressing member that is provided between the electrode and the stretchable cloth and presses the electrode against the living body.

  The contact means may include a fitting member that is provided in each of the living body and the clothes and that fits each other.

  A measuring unit that measures a pressure when the electrode presses the living body; and an adjusting unit that adjusts a stretched state of the stretchable fabric in the contact unit based on a measurement result by the measuring unit. Good.

  The garment includes a first fabric that forms a surface of the garment, and a second fabric that is the stretchable fabric and is provided on the living body side of the first fabric, and the electrode You may install in the said 2nd cloth of the said clothes.

  The garment may further include shape maintaining means for maintaining the shape of the garment in at least a part of an area including an installation place of the electrode.

  As described above, according to the present invention, clothing (such as a human body) and an electrode that receives a biological signal (electrocardiogram / heartbeat / respiration / pulse wave / body temperature / myoelectricity, etc.) are secured, Since a shirt, pants, etc.) can be locally tightened, it is possible to achieve both a reduction in wearing load and an improvement in received signal quality.

There are provided pressure sensor electrodes (61, 62) and pressure monitoring wires (63, 64) for transmitting the measured pressure to the pressure adjusting device (60). By applying a sine wave signal between the sensor electrodes (61, 62) and measuring the impedance between the electrodes, the degree of adhesion of the bioelectrode to the living body can be determined.

  In particular, if the contact surface of the bioelectrode gets wet, the contact surface area effectively increases, so an increase in the contact area appears as a drop in the measured impedance, so it is determined that the electrode is in sufficient contact I can do it. On the other hand, when the measured impedance is high, it can be determined that the contact state is insufficient.

  The arrival pressure adjusting device (60) uses the measurement result of the impedance value to output a warning sound when the impedance value exceeds the set threshold value, and adjusts the arrival pressure of the bioelectrode to the user. Can be urged. When it is recognized that the contact state of the bioelectrode with the human body is insufficient, the close contact degree of the bioelectrode with respect to the human body can be adjusted using the close contact means shown in FIGS.

  Further, as the pressure detection means (68, 69), a bending sensor that grasps the pressure shown in FIG. 9C by converting it into a bending amount can be used. As a bending sensor, for example, Flex Sensor FS754 manufactured by spectrasynbol can be used. By arranging this bending sensor between the living body electrode (12, 13) and the living body (100), it becomes possible to convert a slight bending amount into a pressure. It becomes possible to detect with small-scale hardware.

  Since this bending sensor is made of a thin resin having a thickness of about 1 mm, the sensor can be bent with a pressure sufficient to bring the clothing and the living body into close contact with each other. As shown in Fig. 4, the detection sensitivity of the adhesion pressure can be increased by making the bending amount (angle) correspond to the pressure.
