Description

[Detailed Description of the Invention] The present invention relates to a biological electrode for extracting biological potentials such as electrocardiograms.

Generally, when measuring an electrocardiogram, a method is used in which clip electrodes or dish electrodes are attached to the hands and feet and the electrodes are guided to an electrocardiograph using lead wires.

However, since all of these electrodes had lead wires connected to them, after they were attached to the epidermis of a living body, the lead wires were pulled and connected to the electrocardiograph, causing the electrodes to become dislodged. In addition, heat sterilization was not suitable because the lead wires remained connected.

In addition, the clip electrode was prone to movement and caused noise. Furthermore, since the plate electrode requires a paste, it takes time and effort to attach the plate electrode. Furthermore, if the paste dries, it is necessary to reattach it.

This invention was proposed in order to improve the above-mentioned drawbacks, and the purpose is to obtain a biological electrode that is easy to attach, durable for long-term use, allows the lead wire to be attached and detached, and is suitable for disinfection. And so.

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

FIG. 1 shows a perspective view of the invention. In the figure, 1 is a band-shaped member made of rubber, cloth, vinyl, or the like. Stop members 2a and 2b made of Magic Fastener (registered trademark) or the like are provided on one end surface and the other end surface of the strip member 1, and the stop members can be overlapped and locked in a loop shape. A water-containing member 3 such as cloth is superimposed on one surface of the other end of the band-like member 1 . This water-containing member 3 has a gap portion in which a portion that is not sewn is left. 4 is a conductive elastic material made of rubber, plastic, etc. containing fine particles of carbon or metal. As shown in FIG. 2, this electrically conductive elastic body 4 has a hole 4a at the center which serves as a connection part, and allows insertion of a lead wire connection terminal or the like.

The shape of the conductive elastic body 4 is not limited as long as it can be inserted into the gap of the water-containing member 3, and the connecting portion is not limited to a hole.

FIG. 3 is a perspective view of the lead wire. In the figure, 5 is a lead terminal made of carbon or the like to enable potential extraction. Reference numeral 6 denotes a grip portion that holds the lead terminal 5 and connects it to the lead wire 7. 8 is a metal terminal that allows connection to an electrocardiograph or the like.

Next, an embodiment of the above configuration will be described with reference to FIG. 4 based on an example of electrocardiogram measurement.

FIG. 4 is an explanatory view showing an example in which the band-shaped biological electrode of the present invention is attached to the wrist.

First, the band member 1 is wrapped around the wrist 9. The corresponding rear stop members 2a and 2b are overlapped and combined. In this state, the water-containing member 3 provided on the band member 1 comes into contact with the wrist. Next, a hole 4 that will become a connection part of the conductive elastic body 4 inserted into the gap of the water-containing member 3
Insert the lead terminal 5 into a. On the other hand, the metal terminal 8 of the lead wire 7 is connected to an electrocardiograph or the like. Next, the saline is sucked into a dropper or the like and applied to the water-containing member 3 to release the saline.

As a result, the physiological saline comes into contact with the skin, and the potential of the epidermis changes from the water-containing member 3 containing the physiological saline to the conductive elastic body 4 to the lead terminal 5 to the lead wire 7 to the metal terminal 8, and the electrocardiograph etc.

Next, when removing the biological electrode, hold the grip part 6 with one hand, press the conductive elastic body with the other hand, and pull out the lead terminal. Next, release the connection between the stopper members 2a and 2b and use Magic Fastener (registered trademark).
Open it and release it from your wrist.

In the present invention, since a conductive elastic body is provided and a hole is provided in the elastic body as a connection part, insertion and removal of the lead terminal is extremely easy.

Note that the fastening member is not limited to Magic Fastener (registered trademark), but may also be an adhesive tape, a hook, or a button.

Moreover, the water-containing member 3 does not have to have a gap, but may be formed into a bag.

Further, even if the conductive elastic body 4 does not have the connecting portion 4a such as a hole, the conductive elastic body 4 may be shaped like a hook to form a connecting piece and may be used as a clamping portion for clamping the lead terminal 5.

Using the present invention in this way has the following effects.

The electrodes can be positioned and fixed extremely easily by simply wrapping the band-like member around the hand or foot of the living body.

Further, since the strip member and the lead terminal are formed separately, the connection can be replaced.

In addition, the electrode portion can be disinfected independently.

Furthermore, since it comes into contact with the living body through a water-containing member, not only is there no metal irritation, but even if the physiological saline dries up, it can be replenished with a dropper or the like and potential extraction can be carried out for a long time.

Since the connecting portion is made of a conductive elastic material, it is less likely to be corroded by saline or cause poor connection.
