Description

  The present invention relates to a biological signal detector, and more particularly, to a biological signal detector that can easily detect a biological signal of a body by having a prominent protrusion so as to be in close contact with the surface of a human body. is there.

  Currently, when measuring a biological signal such as a person's heartbeat and brain waves, a plurality of sensor elements of a physiological measuring device are respectively attached (or mounted) to different parts of the surface of the body, and nerve impulses (that is, by these sensor elements) , Changes in membrane potential) pass through body organs (eg, heart and head) to detect the current diffused to the surrounding tissue or body surface, and the detected sensor signal is further physiology from these sensor elements. It is transmitted to the measurement device via the electric wire, and after processing, converted into data and displayed, the situation of the measurement site (for example, heart rate frequency or brain wave change) can be known.

  The above sensor element often uses an electrode piece, and the conventional electrode piece mainly comprises an adhesive base layer (for example, a conductive colloid layer) and a conductive portion coupled to the base layer. When detecting a biological signal, the surface of the body is completely pasted to the surface of the body due to the adhesiveness of the base layer so that the current on the body surface flows to the physiological measurement instrument through the base layer, the conductive part and the electric wire. Become. On the other hand, when current is transmitted from a physiological measurement device to the body surface to deeply enter the body surface and stimulate a site to be treated, so-called electrode treatment is performed.

  However, the surface of the body is a curved surface with many undulations and also includes more protruding parts (for example, shoulders and knees), so there is a gap between the base layer of the conventional electrode piece and the surface of the body In addition, when the body moves, the base layer of the conventional electrode piece may be pushed away by, for example, the periphery of the shoulder rib or the elbow joint, so that a part of the base layer is loosened. It is difficult to stick to the surface of the body, and the entire grace may be disengaged. In such a case, it is difficult to generate a sensor signal, and it is also easy to stop detection. When using an electrode piece, it is inconvenient in use because it needs to be individually affixed and fixed to the surface of the part to be detected of the body.

  In addition, the base layer of the above conventional electrode piece is prone to cracking due to drying, and the human body surface easily adheres to the sweat, which affects the transmission of biological signals, and the sweat remains. Since mold occurs and becomes black, or other dirt (for example, dust) easily adheres to it, noise interference occurs. Further, if the sweat or dirt adheres to the surface of the base layer, the adhesiveness is lost. Since it becomes easy, the conventional electrode piece is easily lost due to the above circumstances, and is inconvenient in use.

  In view of the above, the creator of the present invention deliberately researches, designs, and assembles and detects the biological signal of the person being measured by having prominent protrusions that have the effect of being in close contact with the body surface. A biological signal detector that is easy to use and improves convenience in use is provided.

  The present invention provides a biological signal detector that has a prominent protrusion so as to have an effect of being in close contact with the surface of the body so that the biological signal of the measurement subject can be easily detected and the convenience in use is improved. The main purpose.
