Description

  The present invention relates to a fixing component.

  Conventionally, a belt-type bioelectrode interface has been used for the purpose of obtaining biometric information. In particular, for the purpose of obtaining heart rate information, a belt-type bioelectrode interface that is easy to attach and detach and that is highly integrated with the body has been widely used (for example, see Non-Patent Documents 1 to 3). Recently, with the aging of the population, the importance of long-time heartbeat and electrocardiogram measurement has increased, and various wearable devices including a bioelectrode interface capable of such measurement have been proposed. Moreover, physical management is possible by obtaining biological information on a daily basis with these wearable devices. For example, using a Holter electrocardiograph that can measure for a long period of time, such as 24 hours, and acquiring heart rate information continuously in an active state, it becomes easier to detect abnormal cardiac functions in real life. Yes.

  As described above, various forms of wearable devices have been developed in accordance with the interest and technical level of wearable devices. As an example, a shirt-type wearable electrode capable of comfortable long-time measurement has been developed (see, for example, Non-Patent Document 4). In this shirt-type wearable electrode, the electrode part (interface part) is composed of a composite material of conductive polymer and fiber, so there is no need for conductive paste and long-term heartbeat and electrocardiogram measurements are possible. It is said that. The shirt-type wearable electrode includes polyaniline, polyacetylene, polypyrrole and (3,4-ethylenedioxythiophene) / poly (4-styrenesulfonic acid) (hereinafter referred to as PEDOT-PSS) as conductive polymers. Since PEDOT-PSS is hydrophilic, its biocompatibility is enhanced and its familiarity with the skin is good, so that comfortable long-time measurement is possible. Furthermore, the shirt-type wearable electrode is formed by sewing a connector for connecting to a biological signal measuring device / wireless terminal (hereinafter simply referred to as a terminal) in a pocket of the wear. Therefore, the terminal can be accommodated in the wear pocket. And, since the distance between the heavy terminal and the electrode part can be secured by fixing the terminal in the pocket of the wear, the vibration is transmitted from the band to the electrode part when the terminal vibrates due to body movement. It is possible to prevent noise from being generated.

  Since the terminal generates electrical noise (spike noise) due to body movement, it needs to be fixed to a living body. In conventional Holter electrocardiographs, since the terminal is adhered to the skin using an adhesive tape, it causes a sense of discomfort and itching and redness of the skin. On the other hand, in the wearable electrode, the position where the terminal is placed on the body, that is, the position where there is no hindrance in daily life (for example, it does not hit the shoulder strap of the shoulder bag) and the preferred position vary among individuals. For this reason, it may be difficult to use a shirt type wearable electrode like the structure of nonpatent literature 4. In addition, the position where the terminal is placed on the body differs between the time of activity (daytime) and the time of sleep (nighttime). Therefore, during sleep, it is desirable that the terminal can be placed at a position of the body that is different from the daytime.

  Furthermore, if the biological signal is not constantly measured, if the terminal can be removed, the burden on the body can be reduced and unnecessary impact on the terminal can be avoided. In addition, when the terminal is attached to clothing, it may be inconvenient that it becomes clear from the appearance that the terminal is attached.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a terminal fixing component that enables a terminal to be fixed at an arbitrary position.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below are examples of the present invention, and the present invention is not limited to the following embodiments. Each embodiment can be combined as much as possible.

As shown in FIG. 1, the biological information measuring system 1 includes an electrode 2, a fixing component 3, and a biological signal measuring terminal 4.

  The electrode 2 can be placed in close contact with an appropriate position on the body surface in order to acquire biological information of the subject. Therefore, the material constituting the electrode 2 is a conductive polymer having elasticity and hydrophilicity capable of following a change in the contour of the body surface accompanying the movement of the subject while being in close contact with the body surface having an uneven or curved contour. It is a composite fiber. Examples of the conductive polymer of the conductive polymer composite fiber include pyrrole-based, thiophene-based, isothianaphthene-based, phenylene-based, acetylene-based, and aniline-based conductive polymers, and copolymers thereof. .
