Description

[Detailed Description of the Invention] The present invention relates to an electrode assembly that is attached to a living body via an adhesive tape such as double-sided tape, and particularly to an electrode assembly for a living body in which the adhesive tape can be easily removed after use.

As an example of a conventional biological electrode assembly, an electrocardiogram electrode assembly will be explained based on FIGS. 1 to 3.

A conventional electrode body 1 is composed of an insulating case 2 made of plastic or the like, and a lead-out electrode 3 housed within the case 2 and used to derive an electrical signal from a living body A. The lead-out electrode 3 is usually made of silver/silver chloride.

Further, the case 2 has a disc part 4 and a cylindrical part 5 protruding from the center of the upper surface of the disc part 4, and the lead-out electrode 3 formed in a disc shape is inserted into the cylindrical part 5. be done. Further, an end portion of a lead wire 6 guided to the lead-out electrode 3 is inserted into the cylindrical portion 5 by penetrating the cylindrical portion 5, for example. In this way, the ends of the lead-out electrode 3 and the lead wire 6 inserted into the cylindrical part 5 are protected from the cylindrical part 5 by the insulating material 7 filled in the cylindrical part 5.
Fixed inside.

Further, the disk portion 4 is provided with a ring-shaped double-sided tape 8.
It has an adhesive surface 9 that is fixed to the living body A through the adhesive surface 9, and a hole 10 for applying paste to the lead-out electrode 3 is bored in the adhesive surface 9. This hole 10 is
It is concentric with the center hole 11 of the ring-shaped double-sided tape 8. The ring-shaped double-sided tape 8 is disposable, and when unused, as shown in FIG. 4, a large number of ring-shaped double-sided tapes 8 are arranged and prepared on a release mount 12.

When measuring an electrocardiogram using the conventional electrocardiogram electrode body 1 described above, double-sided tape 8 is pasted on the adhesive surface 9 of the case 2, and then the adhesive surface 9 is attached to the living body A.
It is fixed at the desired location. After the measurement is completed, the electrode body 1
is removed from the living body A, and the double-sided tape 8 is removed from the adhesive surface 9 of the case 2 with fingers in preparation for reuse.

However, in general, the electrode body 1 is desired to be small, lightweight, and thin, and this requirement is especially high when used on premature infants or when used in large numbers in a small area, so the electrode body 1 is compact and difficult to pick up. Therefore, the current situation is that it is actually difficult to peel the double-sided tape 8 from the case 2.

For this reason, conventional practice has generally been to hold the lead wire 6 with one hand and peel off the double-sided tape 8 with the other hand. However, in this case, since tension is applied to the lead wire 6, there is a problem that the lead wire 6 is likely to be cut and the durability of the electrode body 1 is impaired. In particular, when the electrode body 1 is small, the lead wires 6 are also thin, so this problem becomes noticeable and the strength is also impaired.

The present invention was developed in view of the conventional problems as described above, and its purpose is to make the adhesive tape easy to peel off with fingers while being compact, and to avoid the loss of durability and strength when the adhesive tape is peeled off. The object of the present invention is to provide a biological electrode body that is free of oxidation.

In accordance with this objective, the gist of the present invention is to provide the case integrally with a gripping protrusion included in a plane substantially parallel to the plane containing the adhesive surface of the case.

The present invention will be explained below based on the embodiments shown in FIGS. 5 to 9. In addition, the same reference numerals will be used to describe the same parts as in the prior art.

5 and 6 show an embodiment of the present invention, and this electrode body 1a is equipped with an insulating case 2 and a lead-out electrode 3 housed in the case 2, as in the conventional case. 2 has an adhesive surface 9 that is fixed to the surface of the living body A via a double-sided tape 8.

According to the present invention, the gripping protrusion 13 included in a plane substantially parallel to the plane including the adhesive surface 9 of the case 2 is integrally provided on the case 2. In this embodiment, the gripping protrusion 13 has a disk shape, and its center portion is fixed to the upper end of the cylindrical portion 5 of the case 2.

Therefore, when peeling off the double-sided tape 8 from the adhesive surface 9, the gripping protrusion 13 can be pinched with the tip of a finger or a toe, making peeling extremely easy. Also,
Since the gripping protrusion 13 extends almost parallel to the adhesive surface 9, the compactness of the electrode body 1a is not impaired, and the surface facing the bed of the subject lying on the bed etc. There is no hindrance to attaching the device to other devices. Also, since there is no need to pull the lead wire 6,
There is no loss of durability or strength.

7 to 9 show other embodiments of the present invention. In this electrode body 1b, the gripping protrusion 13 is approximately oval, and the outer diameter of the disc part 4 of the case 2 and the outer diameter of the cylindrical part 5 are The diameters are made to match. In this case as well, the same effects as in the embodiment shown in FIGS. 5 and 6 can be obtained.

As is clear from the description of each embodiment, according to the present invention, since the case is integrally provided with a gripping protrusion extending substantially parallel to the surface of the case to be adhered to the living body, the case is compact and has adhesive properties. A biological electrode body whose tape is easily peeled off and whose strength and durability are not impaired can be obtained.
