Description

  The present invention relates to a biological signal detection structure with waterproof performance, and in particular, the electrode piece is moistened by combining the effects of water absorption, waterproofing and moisture retention, the conductive effect for detecting biological signals is improved, and the human body in a dry area The present invention relates to a biological signal detection structure that is applied to detection of a biological signal and is configured to be in contact with the surface of a human body.

  Currently, when measuring biological signals such as human heartbeats and brain waves, a plurality of electrode pieces of physiological measuring devices are attached (or attached) to different parts of the surface of the human body (also referred to as body surface). A piece detects a current diffused to the surrounding tissue or body surface when a nerve impulse (that is, a change in membrane potential) passes through a human organ (for example, heart or head), and further, the current is passed through an electric wire. Is transmitted to the physiological measurement device, converted into data, and displayed, so that the situation of the measurement site (for example, heart rate frequency and brain wave change) can be known.

  The conventional electrode piece is mainly composed of a base layer (for example, a conductive colloid layer) and a conductive portion coupled to the base layer, and is used for adhesiveness or conductivity of the base layer when measuring a biological signal. When the aqueous gel is further applied, the body surface (for example, skin) is wetted, and the current on the body surface flows to the physiological measurement instrument through the base layer, the conductive portion, and the electric wire. 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 water-based gel used in combination with the base layer of the conventional electrode piece has a problem that it is difficult to permeate and is irritable. Substances such as skin debris (generated in the case of dry skin) and oils and fats (generated in the case of oily skin) are discharged, easily adhere to the base layer, obstruct current conduction, and the human body has a body temperature, Moisture on the surface of the body is easily lost (evaporated), or the combined gel dries out and does not form in a wet state, loses adhesion to the base layer and peels off, which also affects current conduction. In particular, in a dry environment, it is difficult to retain moisture, a situation where detection is stopped easily occurs, and the base layer may be cracked.

  In addition, when a plurality of conventional electrode pieces are used, if the conventional electrode pieces are positioned adjacent to each other, they may easily come into contact with each other and may become a short circuit.

  In view of the above, the creator of the present invention has been dedicated to research, design, and assembly, combining the effects of water absorption, waterproofing and moisture retention, improving the conductive effect of detecting biological signals, and the human body in dry areas It is a motivation that the present invention intends to create a waterproof biological signal detection structure that is easy to apply to the detection of biological signals and that improves convenience in use.

The main object of the present invention is to provide a waterproof biological signal detection structure that can be easily applied to detection of a biological signal of a human body in a dry area and that improves convenience in use.

  The present invention provides a biosignal detection structure with waterproof performance that is less affected by current conduction by bonding a thermoplastic bonding layer so as to have a positioning effect in addition to being easy to combine and use. With the following purpose.

  Another object of the present invention is to provide a waterproof biological signal detection structure having a protrusion that is conspicuous after water absorption so that it can be easily attached in close contact with the surface of the body.

At least one electrode piece, at least one water absorbing means positioned in the first receiving chamber, with a ceiling portion in contact with the electrode piece and a bottom portion in contact with the waterproof bottom layer, and the waterproof bottom layer The upper layer has at least one upper layer opening provided to be exposed so that the electrode piece is exposed, and a bottom edge of the upper layer opening correspondingly overlaps the upper surface edge of the electrode piece. By including a waterproof upper layer in which the middle part of the electrode piece protrudes from the opening, it has effects of water absorption, waterproofing and moisture retention, preventing moisture from being lost quickly, and to conducting current due to infiltration of external liquid Impact of It can be prevented and noise interference is reduced, it becomes easy to wet the electrode pieces, and each electrode piece is raised by water absorption by the water absorption means, and it is easy to attach the electrode pieces to the surface of the body and attach them tightly, so that the person to be measured This makes it easier to detect the biological signal of the device, improves the convenience in use, and further, by adding a thermoplastic bonding layer (for example, the first bonding layer or the second bonding layer), it is easy to bond and use. In addition, it has the effect of positioning, makes it easy to align the water absorption means with the electrode piece, and further has the effect of avoiding the influence on current conduction due to slipping.
