Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bioelectrode holding device that allows a bioelectrode to be brought into good contact with and held at a detection target site with a simple operation.

Conventionally, bioelectrodes have been held and fixed by pasting them with adhesive tape such as bandages or by inserting them into rubber bands. However, although this type of conventional fixing method has achieved the purpose of holding the electrode, it has the disadvantages that the operation is complicated and removal is accompanied by considerable discomfort.

The present invention provides an electrode holding device that can be attached and detached very easily and that can also contact and hold electrodes very well.

The structural features of the present invention include a flexible belt-shaped sheet that can completely adhere to the shape and irregularities of the area to be detected for biological signals, and elasticity that allows this sheet to contact the area to be detected with appropriate pressure. The bioelectrode is arranged on the concave side of the flexible strip sheet. Therefore, a major feature of the bioelectrode is that it can be completely attached to the detection site regardless of its shape, that it can be held and fixed with appropriate pressure, and that it can be attached and detached extremely easily.

Next, specific examples of the present invention will be described. In Figure 1, 1 is a U-shaped spring with elasticity;
For example, it is made from a metal plate such as stainless steel or molded plastic. Reference numeral 2 is a thin and flexible sheet made of, for example, a rubber sheet or a plastic sheet, and both ends of the sheet are fixed near the inner end of the U-shaped spring 1. 3 is a bioelectrode, and a necessary number of electrodes are pasted on the concave side of the sheet 2. The size of the U-shaped spring 1 differs depending on the part to be detected, but for example, when detecting electroencephalograms or electromyograms from the forehead, the U-shaped spring 1 should surround approximately half the circumference of the head, as shown in Fig. 2. Size. Further, when the detected part is an electromyogram or skin resistance of an arm, etc., the U-shaped spring 1 is made large enough to almost sandwich the arm, although not shown in the figure. Although there are individual differences in the size and shape of the head and arms, these individual differences can be completely absorbed by the flexible sheet 2.

FIG. 3 shows another embodiment of the invention. This embodiment is suitable for cases where the size of the detection target region is extremely different, such as between a child and an adult.
In the figure, the same parts as in FIG. 1 are given the same reference numerals, and their explanation will be omitted. Reference numeral 4 indicates a screw for adjusting the seat mounting position, and reference numeral 5 indicates a groove formed in the U-shaped spring 1. In this embodiment, the size of the sheet 2 relative to the detection area is adjusted by moving the sheet mounting position adjustment screw 4 attached to the sheet 2 within the cut groove 5 of the U-shaped spring 1 and tightening and fixing it at a desired position. Can be adjusted.

As described above, the present invention includes a U-shaped structure having elasticity, a flexible belt-like sheet that is inscribed and fixed near the tip of this structure, and that can closely fit along the shape of a biosignal detection site. This bioelectrode holding device is equipped with at least one biosignal deriving electrode provided on the inner surface of the sheet and is removably attached to the biosignal detection site of the human body. Easy to operate and remove,
Very useful in practice.
