BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure of an electrode for leading a signal from an adhesive electrode used for measuring a bioelectric signal such as an electrocardiogram to the outside.

[0002]

2. Description of the Related Art For example, when measuring a bioelectric signal such as an electrocardiogram, an electrode formed by forming a conductive adhesive layer on one surface of a sheet-like conductive terminal is connected to the chest of a subject via the adhesive layer. And the like, and the conductive terminal of the electrode is clamped by a clip, and the measurement is performed by connecting to a measuring device provided outside via an induction cord connected to the clip.

FIG. 4 shows an example of the structure of a conventional clip. In FIG. 4, a central portion of a movable portion 3 is rotatably attached to a base 1 formed in a substantially planar shape via a shaft 2. A conductive portion 4 formed of metal in a plate shape is provided on a surface of the base portion 1 facing the movable portion 3, and a saw-toothed holding portion is provided on a surface of the movable portion 3 facing the conductive portion 4 at one end. 5 are formed. In addition, an induction cord 6 is connected to one end of the conductive portion 4 on the side opposite to the holding portion 5. Further, a spring member 7 for urging the holding portion 5 in a direction of pressing the conductive portion 4 against the conductive portion 4 is mounted between the base portion 1 and the movable portion 3. Then, the conductive terminal of the electrode is held between the holding section 5 and the conductive section 4 to derive a signal.

[0004]

However, according to the conventional electrode clip constructed as described above, since the conductive terminals of the electrodes are formed of a thin and slippery metal sheet, the clips hold the conductive terminals. In such a case, it was easy to come off, and there was a risk that the inspection would be hindered. In addition, when the urging force of the spring member 7 is increased in order to make it difficult to come off, there is a problem that the operability of attaching and detaching is reduced.

The present invention has been made in view of such a situation, and provides an electrode connection structure that can securely hold an electrode without coming off and can be easily attached and detached. The purpose is to:

[0006]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a sheet-like conductive terminal having a conductive pressure-sensitive adhesive layer formed on one side of the conductive terminal, and sandwiching the conductive terminal.
In the connection structure of the electrode with an electrode clip led outside through induction encoding bioelectrical signal, the electrode
Through holes are formed in advance at the ends of the conductive terminals.
In addition, a projection is provided at the tip of the clip,
The projection is inserted into the through hole .

[0007]

According to the above construction, the electrode is clamped by the clip in a state where the projection provided on the clip is inserted into the through hole formed in the electrode, so that the electrode is securely clamped and fixed without coming off. Can be. Further, since a strong spring force for holding the electrode is not required, the electrode can be easily attached and detached by the clip.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an electrode clip according to an embodiment of the present invention;

FIGS. 1 and 2 show the configuration of an embodiment of the present invention. In these figures, portions corresponding to those of the conventional example shown in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. The feature of the present embodiment is that a projection 9 is provided at the sandwiching end of the clip 8, and the projection 9 is inserted into a through hole 11 a formed near one end of a sheet-shaped metal conductive terminal 11 constituting the electrode 10. The point is that the electrode 10 is clamped and fixed between the conductive portion 4 and the clamping portion 5. Reference numeral 12 shown in FIG. 1 denotes a conductive adhesive layer formed on one surface of the conductive terminal 11, and the conductive portion 4 and the spring material 7 shown in FIG. 4 are omitted in FIG.

FIG. 2 shows a configuration example of the projection 9. 2A, a projection 9 is provided near the distal end of the movable portion 3 of the clip 8 toward the base 1 side, and a through hole 1a into which the projection 9 is inserted is formed in the base 1 at a position where the projection 9 faces. It is an example. In this case, as shown in (b), the protrusion 9 may be provided on the base 1 side, and the through hole 3a may be formed on the movable portion 3 side, or the through hole may be formed as the blind hole 1b as shown in (c). Good. Although not shown, the through hole 3a shown in (b) may be a blind hole.

Further, as shown in FIG.
For example, two holes may be provided and a through hole or a blind hole may be formed at the position of the base 1 or the movable portion 3 facing the protrusion 9.
Further, as shown in (e), the protrusion 9 may be provided outside the end face of the movable portion 3 so that the through hole 11a of the conductive terminal 11 can be easily inserted into the protrusion 9. Also, as shown in (f),
A step 1c is provided inside the protrusion 9 of the base 1 shown in FIG. 3E, and the conductive terminal 11 is positioned against the inner end face of the step 1c to insert the protrusion 9 into the through hole 11a. May be easier. The example shown in FIG.
FIG. 2 (e) shows the case of FIG.

According to this embodiment, the conductive terminal 1 of the electrode 10
Since the conductive terminal 11 of the electrode 10 is held between the conductive portion 4 of the clip 8 and the holding portion 5 in a state where the protrusion 9 provided on the clip 8 is inserted into the through hole 11 a formed in the first member 1, The electrode 10 can be securely held by the clip 8 without coming off. In addition, since the strong urging force of the spring member 7 for clamping is not required, the attachment and detachment of the electrode 10 by the clip 8 can be easily performed.

In this embodiment, grooves 1d are provided on both sides of the substrate 1, both sides of the movable portion 3 are bent, and the bent portions 3b are slidably fitted in the grooves 1d. When the movable portion 3 is elastically deformed, the projection 9 provided on the substrate 1 is fitted into the concave portion 3c formed in the movable portion 3.

According to this embodiment, the support shaft 2 shown in FIG. 1 and the spring member 7 shown in FIG. 4 are unnecessary, and the configuration can be simplified.

The configuration of the protrusion 9 and the like shown in each of the above embodiments is merely an example, and the present invention is not limited thereto.
