Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a biological electrode connector that is connected to an electrode attached to a living body and supplies electrical signals from the living body to medical equipment.

[Conventional technology]

Generally, a disposable electrode 1 as shown in Fig. 7 is used as a bioelectrode for extracting bioelectrical signals such as an electrocardiogram.
0 is widely used. This disposable electrode 10
Figure 6-
The one shown in Figure 8 was proposed (Jetko Kokō 56-40411).
It has been put into practical use.

FIG. 6 is a perspective view showing the bioelectrode connector 1 attached to the disposable electrode 10, and FIG.
6 and 8 are bottom views of the bioelectrode connector 1. The bioelectrode connector 1 includes an insulating case 2, an insulating sliding body 3, a spring 4, and a lid 5. Openings 6a and 7a are provided on the lower surfaces of the insulating case 2 and the sliding body 3.
The metal plates 6 and 7 with the metal plates 6 and 7 are bonded together. The sliding body 3 is also provided with a through hole 3a into which the hook portion 10a and neck portion 10b of the disposable electrode 10 are inserted.
The lead wire 8 is electrically connected to the metal plate 6 inside the insulating case 2. Furthermore, pressing parts 2a and 3a protruding from the insulating case 2 are formed at opposing positions, and the pressing part 3b can freely enter and exit the notch 9 of the insulating case 2. The disposable electrode 10 is composed of an adhesive sheet 11 and an electrode plate 12 having a hook portion 10a and a neck portion 10b.

When using, press the pressing part 2a of the insulating case 2 and the pressing part 3b of the sliding body 3 with your fingers, align the opening 7a of the metal plate 7 with the opening 6a of the metal plate 6, and then press the electrode plate 1.
2, and release the pressure at the neck 10b. Since the sliding body 3 receives a repulsive force outward from the insulating case 2 by the spring 4, the neck portion 10b is held between the metal plates 6 and 7.

[Problem that the invention attempts to solve]

Generally, when using a bioelectrode, an electrolyte paste is used to ensure electrical contact with the living body. Further, a disinfectant solution is used for the purpose of disinfecting the bioelectrode connector 1. As is clear from the above description, the conventional bioelectrode connector 1 has an opening 6a.
The structure is almost closed except for 7a and 7a. For this reason, paste and disinfectant may adhere to and accumulate on the sliding body 3 and inside the electrodes during use, and if left unattended, the paste and disinfectant will dry and solidify, causing the sliding body 3 to stick. , it often became impossible to attach it to the disposable electrode 10. In this case, it may be necessary to clean it after use, but the paste and disinfectant that have accumulated inside cannot be sufficiently cleaned because the openings 6a and 7a are narrow. In addition, since the number of manufacturing parts is large, a corresponding amount of assembly man-hours is required.

It is an object of the present invention to solve the above-mentioned problems and provide a bioelectrode connector that does not require sealing the sliding body portion, has a simple configuration, and is easy to handle.

[Means for solving problems]

The present invention has a U-shaped elastic metal plate 13 in a bioelectrode connector 14 attached to a hook portion 10a of a bioelectrode 10 as shown in FIGS. 1 to 5, for example.
Rings 13 overlap each other near the tips of both ends of the
a and 13b are formed and resin molded so as to cover this elastic metal plate 13, and these rings 13a, 13b are formed.
The opening of the bioelectrode 13b engages and holds the hook portion 10a of the bioelectrode 10.

[Effect]

In this invention, the bioelectrode connector 14
To attach the U-shaped elastic metal plate 13 to the hook part 10a of the bioelectrode 10, the vicinity of both ends of the U-shaped elastic metal plate 13 is pressed against the biasing force of the elastic metal plate 13 and the resin mold, and the center openings of the rings 13a and 13b are opened. is the fourth
As shown in the figure, the hook part 10a of the bioelectrode 10 is penetrated into the overlapping central opening by overlapping the openings to maximize the openings, and then the pressing is stopped and the U-shaped elastic metal plate 13 is inserted into the overlapping central opening. As shown in FIGS. 1 and 2, the rings 13a and 13b are used to open the ends of both sides of the bioelectrode 1.
0 hook part 10a, and when removing it, do the opposite. Therefore, according to the present invention, since the rings 13a and 13b are not surrounded, the attached paste and disinfectant can be easily cleaned with a brush or the like, and the bioelectrode is placed in the center opening of the rings 13a and 13b. Since it can be inserted while looking at the hook part 10a of 10, it can be quickly attached.Furthermore, the synergistic effect of the elastic force of the elastic metal plate 13 and the molded resin ensures engagement and retention with the bioelectrode 10, and furthermore, the number of parts is small. The structure becomes extremely simple.

〔Example〕

Hereinafter, one embodiment of the bioelectrode connector of the present invention will be described with reference to FIGS. 1 to 5. In FIGS. 1 to 5, parts corresponding to those in FIGS. 6 to 8 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

In this example, as shown in FIG.
3 is bent almost into a U-shape, and rings 13a and 13b are placed at opposite positions near the tip on both sides.
Prepare one that is arranged so that they overlap each other. The rings 13a and 13b have central openings of approximately the same diameter. In this example, the elastic metal plate 13 is provided with lead wires 8 and is molded with resin as shown in FIGS. 1 and 3 to insulate it. When molding with this resin, the resin is molded from both ends of the elastic metal plate 13 to the vicinity of the rings 13a and 13b to form a shape that surrounds the elastic metal plate 13. At this time, the elastic metal plate 13 and the lead wire 8 are electrically connected in advance. The bioelectrode connector 14 is now completed. Base part 15 when resin molding
The elastic force can be adjusted by changing the thickness of the elastic parts 15a and 15b.

When in use, the disposable bioelectrode 10 is compressed by pressing both sides of the bioelectrode connector 14 with fingers until the center openings of the rings 13a and 13b form a substantially concentric circle as shown in FIGS. 3 and 4. Insert the hook portion 10a and release the pressure with the neck portion 10b. When the pressure is released, a restoring force is applied by the elastic force of the elastic metal plate 13 and the elastic force of the elastic parts 15a and 15b of the molded resin, and as shown in FIGS.
is engaged and held by.

Therefore, according to this example, the rings 13a and 13b attached to the bioelectrode 10 of this bioelectrode connector are not surrounded, so that the adhered paste and disinfectant can be easily cleaned with a brush or the like. Furthermore, since the bioelectrode 10 can be inserted into the center opening of the rings 13a, 13b while looking at the hook portion 10a of the bioelectrode 10, there is an advantage that the bioelectrode 10 can be quickly attached. Furthermore, according to this example, the bioelectrode 1 is
0 engagement and retention is performed, and this engagement and retention is made that much more reliable. Furthermore, according to this example, the number of parts is small and the structure is extremely simple, which has the advantage of making manufacturing easier and cheaper.

It goes without saying that the present invention is not limited to the above-described embodiments, and that various other configurations may be adopted without departing from the gist of the present invention.
