Abstract

(57) [Summary] [Purpose] When deriving biological signals such as electrocardiograms from the body surface, the contact electrode surface may rise due to body movement, or the entire electrode may sway due to external force applied to the electrode cable, causing the input biological signals to be distorted. Prevent signal quality degradation. [Structure] The electrode main body part 10 and the snap connection part 30 for extracting biological signals to the outside are separated, and a conductive fiber cable 20 is used to connect them. The electrode main body 10 is formed of a thin and highly flexible support 11 and a conductive adhesive sheet 12 coated on one side of the support 11 to provide good adhesion to a living body. The cable between the electrode body 10 and the snap connection 30 absorbs the tensile force.

Description

[Detailed explanation of the idea]

0001

【Technical field】

This invention relates to pasted electrodes, especially those used to derive biological signals such as electrocardiograms. The present invention relates to electrodes that can be attached to living organisms.

0002

[Prior art]

Such a conventional pasted electrode has a structure as shown in FIG. In the figure, (A) is a side view of the electrode, and (B) is a plan view. In the center of the disk-shaped electrode support 1 A snap fastener 2 is installed, and the snap fastener 2 is installed directly below this fastener 2. A gel-impregnated part 3 is arranged in contact with 2.

0003 Adhesive glue 4 is applied all over the lower surface of the support plate 1 around this gel-impregnated part 3. There is.

0004 In such a structure, a conductor is connected to the lower surface of the electrode support 1 directly under the snap fastener 2. Add electrical gel 3, bring the gel into contact with the skin of a living body (not shown), and snap Connect a snap with a lead (not shown) to the fastener 2 to guide the biological signal to the outside of the electrode. It is supposed to be released.

[0005] This snap with a lead prevents it from shaking due to body movements or external mechanical forces. Especially in applications where continuous body movement is applied, such as exercise load tests. The biosignal cannot be recorded reliably unless it is pressed with fixing tape etc. Sometimes.

[0006] In addition, the adhesive support 1 is not thin enough, and its flexibility is not uniform. , it has poor adhesion to the skin surface and lifts from the skin surface due to body movement, making it unreliable. This method has the disadvantage of causing deformation of the signal waveform.

[0007]

[Purpose of invention]

Therefore, the present invention was devised to eliminate the drawbacks of such prior art, and The purpose of this is to improve the accuracy of tests during exercise stress tests that involve large body movements. Our goal is to provide a pasted electrode that can record accurate and stable biological signals with low noise. Ru.

[0008]

[Structure of the idea]

The pasted electrode according to the present invention consists of a thin and highly flexible support plate, and one main surface of this support plate. a conductive adhesive sheet coated on a surface; the conductive adhesive sheet and the support plate; A flexible conductive cable is clamped at one end between the A snap connection made by laminating an adhesive sheet and a snap fastener. It is characterized by including a section.

【Example】

Embodiments of the present invention will be described below with reference to the drawings.

0010 FIG. 1 is a diagram showing the configuration of an embodiment of the present invention, and (A) shows the configuration of an embodiment of the present invention. (B) is a side view of the electrode main body, and (B) shows the entire embodiment of the present invention including this electrode main body. FIG. 1C is a side view of a snap fastener part constituting an embodiment of the present invention.

[0011] The present invention includes an electrode body 10 that detects biological signals, and a transmitter that transmits the biological signals. Relays the transmission signal from the carbon fiber cable 20 and this cable 20 This snap connection part 30 has a lead to be described later. Connect the attached snap (not shown) to guide and extract the biological signals to the outside. It has become.

0012 First, the electrode main body 10 includes a thin and flexible disk-shaped support 11 and this support 1. 1, and a conductive adhesive glue 12 coated over one main surface of the film. this support The body 11 is made of soft cloth or paper pulp that is breathable to the skin and has good moisture absorption. Made of quality materials.

[0013] A carbon fiber for signal transmission is provided between the support 11 and the adhesive glue 12. One end of the fiber cable 20 is clamped. This carbon fiber cable 20 is conductive because it transmits biological signals to the snap connection part 30. The thickness should be thin, and the total line length should be about 100 mm.

[0014] A snap connection part 30 is connected to the other end of this cable 20. This space The nap connection part 30 includes an adhesive sheet 33 for sticking and fixing on the skin surface, and a strip. A magnetic plate 32 that attracts and holds the nap fastener 31 and a snap with a lead. A structure in which snap fasteners 31 for connecting (not shown) are laminated in this order. It is constructed.

[0015] FIG. 2 shows how the fiber cable 20 and the snap connection 30 are connected from the electrode main body 10 FIG. Snap connection 30 Attach the snap 40 with a lead to the nap clasp 31. The biological signals are extracted to the outside through the leads.

[0016] FIG. 3 is a diagram showing an example of the use of the embodiment of the present invention in living organisms. Place the electrode main body 10 on a living body. Paste it on the designated area and gently curl the carbon fiber 20. It absorbs the tensile force and attaches the snap connection part 30 to the biological surface using the adhesive sheet 33. Paste and fix in the desired position. After that, attach the leaded snap 40 to this snap. By connecting to the connection unit 30, preparations for deriving biological signals are completed.

[0017] The electrode main body 10 has a bonding area that provides a sufficiently small contact resistance, and Because it is necessary to avoid being affected by uneven movement of the skin surface, The dimensions shall be approximately 30mm in diameter.

[0018]

[Effect of the idea] As explained above, according to the present invention, on one side of a sufficiently thin and flexible support, The applied conductive adhesive glue adheres to the skin surface, so body movements will not cause the skin surface to fluctuate. The electrode body has a thin and flexible structure instead of having a contact part. Snap leads with snap connections connected to soft carbon fiber cable Since it is connected to the terminal section, it has the effect of buffering external tensile force directly from the cable. There is fruit.

[0019] In addition, the snap connection part has a laminated structure of an adhesive sheet and a snap fastener. It can be attached and fixed to any part of the body surface, and it also comes with an adhesive sheet and a snapper. If you use a magnet between the top and the clasp, the magnet's suction force will cause the snap to snap. Since stable contact is maintained, it is suitable for testing during exercise load tests that involve large body movements. This has the effect of recording biological signals with less fluctuation and noise.
