Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a bioelectrode pad cleaner, for example, an electrode of a therapeutic device such as a low-frequency therapeutic device or a measuring device such as an electrocardiogram measuring device. The present invention relates to a bioelectrode pad cleaner that removes dirt adhering to the surface of the electrode pad for fixing to the electrode.

[Prior Art] In recent years, in the medical field, as a substitute for a conductive cream or paste for improving the adhesion between the skin and an electrode, a conductive hydrogel obtained by crosslinking a hydrophilic polymer by some method has been used. Bioelectrode pads have been disclosed or put on the market. Most of the bioelectrode pads are disposable, but those that can be used by removing dirt from the pad surface have used water or alcohol to remove dirt such as skin adhering to the pad surface.

[Problems to be solved by the invention] However, when water or alcohol is used to clean the electrode pad, the surface of the conductive hydrous gel is in a state of containing an excessive amount of water, which reduces the adhesive strength. Will end up. In the case of a hydrous gel, the adhesive strength changes depending on the amount of water, so that there is a problem that it takes time for the water to evaporate from the surface of the gel and the adhesive strength to be recovered.

An object of the present invention is to solve the above-mentioned problems, and to provide a biological electrode pad cleaner that can easily remove dirt attached to the surface of the electrode pad and that quickly recovers the adhesive force of the pad.

[Means for Solving the Problems] In order to achieve such an object, the present invention provides a laminated structure in which a pressure-sensitive adhesive layer having a greater lipophilicity than a hydrogel is formed on a non-adhesive substrate. It is characterized by having.

[Function] When a bioelectrode pad made of a conductive hydrogel was used and peeled off from the skin, oil and dirt of the skin adhered to the surface of the pad, and the adhesive strength was extremely lowered.

Therefore, if the cleaner of the present invention in which the acrylic adhesive is applied to the base material is attached to the surface of the pad and then peeled off, all the oil and dirt attached to the surface of the pad are transferred to the adhesive layer of the cleaner, The surface condition was restored. The adhesive strength of the pad is almost the same as before use, and it can be used repeatedly.

The reason why the surface condition of the water-containing gel is restored is that the oil and stains on the skin surface are lipophilic, so that the hydrophilic adhesive gel has a higher affinity than the water-containing gel, which is more hydrophilic. Therefore, it is considered that the oil and dirt on the skin adhering to the surface of the pad were removed. The same applies when a rubber-based adhesive is used.

Embodiment Hereinafter, the present invention will be described in detail with reference to the drawings. First
8 to 8 show a bioelectrode pad cleaner according to an embodiment of the present invention.

FIG. 1 shows the structure of a single-body bioelectrode pad cleaner according to the first embodiment. In this pad cleaner, an acrylic or rubber adhesive 2 and a base material 1 made of paper or a plastic film are provided on the silicone-treated side of a release paper 3 having one surface treated with silicone.
The adhesive 2 and the substrate 1 are laminated in this order.

At the time of use, the release paper 3 is peeled off, the adhesive 2 is attached to the surface of the electrode pad made of a conductive hydrogel, and then peeled off.

The thickness of the substrate 1 is 25 to 250 μm, and the thickness of the adhesive is 5 to 1000
The thickness of the release paper is 25 to 250 μm.

Various kinds of paper, polyester film, vinyl chloride film, polypropylene film and the like can be used as the base material 1, but paper (basis weight 40 g / m ² ) is preferable from the viewpoint of cost.

As the release paper 3, any release paper such as glassine paper, clay coated paper, polyethylene laminated paper or the like which has been normally used can be used.

FIG. 2 shows a second embodiment. This electrode pad cleaner is one in which the single body substrate 1 shown in FIG. 1 is extended to form a knob. Providing such a knob has the advantage of facilitating handling.

FIG. 3 is a plan view of a plurality of bioelectrode pad cleaners according to the third embodiment. In this pad cleaner, at least a portion of the cleaner 4 is constructed in the same manner as the single body shown in FIG. 1, and a cut (die cut) 6 is made in the size of the cleaner 4. At the time of use, remove the cleaners 4 one by one from the release paper 3.

The pad cleaner shown in FIG. 3 is easy to use because there are a plurality of cleaners on one plane.

FIG. 4 is a plan view showing the fourth embodiment. In this bioelectrode pad cleaner, at least a portion indicated by reference numeral 7 has a cut 6 formed in a sheet having the same structure as the single body shown in FIG. No adhesive is applied to the base material in the portion indicated by reference numeral 8, and a knob similar to that of the single body shown in FIG. 2 is formed.

This pad cleaner is the same as the one shown in FIG.
It has the advantages of both of those shown.

FIG. 5 shows the structure of a laminated body of the bioelectrode pad cleaner according to the fifth embodiment. This pad cleaner is a laminate of the single bodies shown in FIG.

The base material 1 and the release paper 3 are naturally bonded between the single bodies. Since this pad cleaner is a laminated body, it is convenient because after removing one, the next one is ready for use.

The bioelectrode pad cleaner shown in FIG. 6 is a laminate of the single bodies shown in FIG. This pad cleaner has the advantages of both the one shown in FIG. 2 and the one shown in FIG.

The bioelectrode cleaner shown in FIG. 7 is also a laminated body.
In this bioelectrode cleaner, one having one side treated with silicone is used as the base material 9. Adhesive 2 on release paper 3,
The side of the base material 9 not treated with silicone is stacked on the pressure-sensitive adhesive 2 so as to be in contact with the pressure-sensitive adhesive 2, and several sets of the pressure-sensitive adhesive 2 and the base material 9 are stacked on it to form a laminate.

Since there is a single layer between the adhesive and the adhesive in this laminated body,
It can be made thinner than that shown in the figure.

The laminated body shown in FIG. 8 is the same laminated body as that shown in FIG. 7 with the same knobs as shown in FIG.

[Effects of the Invention] As described above, according to the present invention, it is possible to easily remove oil and dirt on the skin adhered to the biogel electrode pad made of a conductive gel and easily activate the tack on the pad surface. Therefore, there is an effect that the biomedical electrode pad can be repeatedly used.
