Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode material used as a conductor of a low-frequency therapeutic device or the like which is attached to a human body.

[0002]

2. Description of the Related Art As an electrode material to be attached to a human body of this type,
The present applicant has already proposed a structure as shown in FIG. 11 (Japanese Utility Model Application No. 4-91985). This electrode material is attached to a corner portion of a base material sheet 102 having a conductive layer 101 on the lower surface by protruding a convex terminal 103 in contact with the conductive layer 101 to the upper side of the base material sheet and attaching the convex terminal. The non-adhesive layer 104 is provided on the lower surface of the corner portion, and the conductive adhesive layer 1 is formed on the entire lower surface of the other part of the base sheet 102.
05 is provided.

The electrode material having such a structure is composed of a conductive adhesive layer 10
It is attached to the human body by the adhesive force of 5, but the non-adhesive layer 1
Since the corner portion provided with 04 is not attached to the human body and serves as a so-called "turning margin", there is an advantage that the electrode material can be easily peeled from the human body by pinching this corner portion with a finger.

[0004]

However, since the boundary line L between the non-adhesive layer 104 and the conductive adhesive layer 105 is a straight line diagonally crossing the corner portion in the above electrode material, the non-adhesive layer 104 is provided. When the corner portion is pinched and peeled off from the human body, as shown by the alternate long and short dash line in FIG.
02 and the conductive layer 101 on the lower surface thereof bend at the boundary line L, and the base sheet 102 and the conductive layer 101 easily break at the boundary line L while the electrode material is repeatedly attached to and removed from the human body. was there.

The present invention has been made in view of the above problems, and an object thereof is to prevent the base sheet and the conductive layer from being broken at the boundary portion between the non-adhesive layer and the conductive adhesive layer, which is desirable. Is to provide an electrode material that can be easily peeled off from the human body.

[0006]

In order to achieve the above object, the electrode material according to claim 1 of the present invention is brought into contact with a conductive layer at a position excluding a corner portion of a base sheet having a conductive layer on the lower surface. Attach the protruding terminal by protruding it above the base sheet.
It is characterized in that a non-adhesive layer is provided on the lower surface of the terminal attachment portion of the base material sheet, and a conductive adhesive layer is provided on the entire lower surface of the base material sheet excluding the terminal attachment portion.

In the electrode material according to the second aspect of the present invention, a convex terminal which comes into contact with the conductive layer is attached to the base sheet having a conductive layer on the lower surface so as to project above the base sheet. A non-adhesive layer is formed on the lower surface of the terminal mounting portion of the sheet, and a conductive adhesive layer is formed on the entire lower surface of the base sheet excluding the terminal mounting portion so that the boundary line between the non-adhesive layer and the conductive adhesive layer is non-linear. It is characterized by being provided in each.

Preferably, the non-adhesive layer is surrounded by a conductive adhesive layer, or the non-adhesive layer is formed from the lower surface of the terminal mounting portion of the base sheet to one end or both ends of the base sheet. Alternatively, the strip-shaped non-adhesive layer may be extended to the corner end, and the width of the strip-shaped non-adhesive layer may be maximized at the tip portion of the non-adhesive layer.

[0009]

Operation: Like the electrode material of the present invention, convex terminals are attached to the base sheet at locations other than the corners, a non-adhesive layer is provided on the bottom surface of the base sheet terminal attachment locations, and the bottom surface excluding the terminal attachment locations When the conductive adhesive layer is provided on the whole, the boundary line between the non-adhesive layer and the conductive adhesive layer does not become a straight line that crosses the electrode material. Therefore, even if the electrode material attached to the human body is peeled off by the adhesive force of the conductive adhesive layer, the base sheet and the conductive layer on the lower surface thereof do not bend at the boundary line between the non-adhesive layer and the conductive adhesive layer. Even if the electrode material is repeatedly attached to and removed from the human body, there is no concern that the base sheet or the conductive layer will be broken at the boundary. The same action is achieved with an electrode material in which the boundary line between the non-adhesive layer and the conductive adhesive layer is made non-linear.

In particular, in the electrode material in which the non-adhesive layer is surrounded by the conductive adhesive layer, the boundary line between the two is annular, so that the base material sheet and the conductive layer do not bend even if peeled from any direction. In addition, the electrode material provided with a non-adhesive layer extending in a strip shape from the lower surface of the terminal mounting portion of the base sheet to one side edge or both side edges of the base sheet, or the corner edge, the non-adhesive layer is attached to the human body. Since it does not exist, the tip portion of the extended non-adhesive layer can be flipped up with a fingertip, and the electrode material can be easily peeled off toward the strip-shaped non-adhesive layer. In that case, the electrode material provided by extending the non-adhesive layer in a strip shape from the lower surface of the terminal attachment portion of the base material sheet to one side edge or the corner edge of the base material sheet is the boundary line between the non-adhesive layer and the conductive adhesive layer. Has a U-shape or a U-shape and is not a straight line that crosses the electrode material, and therefore there is no fear that the base sheet or the conductive layer is bent and broken at this boundary portion. In addition, in the electrode material in which the non-adhesive layer is provided by extending in a strip shape from the lower surface of the terminal mounting portion of the base material sheet to both ends of the base material sheet, the boundary line between the non-adhesive layer and the conductive adhesive layer crosses the electrode material. Since it becomes two straight lines, if the electrode material is peeled off in the direction perpendicular to this boundary line, the base material sheet and the conductive layer are easily bent and broken at the boundary line, but as described above, this electrode material is extended. Since the tip of the non-adhesive layer is peeled off with a fingertip and peeled in the direction of the strip-shaped non-adhesive layer, the direction of the boundary line and the direction of peeling the electrode material coincide, and therefore the boundary line is the electrode. Even if it is a straight line that traverses the material, there is no concern that the base sheet or the conductive layer will bend and break at the boundary.

Further, in the electrode material in which the width of the non-adhesive layer extended in the shape of a strip is maximized at the tip portion of the non-adhesive layer, when the electrode material is peeled off, the tip of the finger tip between the tip portion of the non-adhesive layer and the skin. It's easy to get in between, so you can turn it up more easily.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the electrode material of the present invention, FIG. 2 is a sectional view thereof, and FIG. 3 is a bottom view thereof.

1 to 3, reference numeral 1 denotes a conductive layer 1 on the lower surface.
A square base sheet including a, in which a terminal insertion hole 1b is formed in the center of the base sheet 1, and a convex terminal 2 is formed.
Is installed. Therefore, as will be described later, the non-adhesive layer 3 provided on the lower surface of the terminal attachment portion of the base sheet 1 is
It will be surrounded by the conductive adhesive layer 4 provided on the entire lower surface excluding the terminal mounting portion.

The shape of the base sheet 1 is not limited to a square, but may be any desired shape such as a rectangle, an ellipse, an oval, a circle, and the position of the terminal insertion hole 1b is also the base sheet 1.
It may be formed anywhere, not limited to the center. However, when there is a corner portion such as a square or rectangular base sheet and the boundary line between the non-adhesive layer 3 and the conductive adhesive layer 4 is a straight line, the terminal insertion hole 1b is provided at a position other than the corner portion. Must be provided.

The base sheet 1 has a thickness of 20 to 250.
It is made of synthetic resin sheet (including film) of about μm, for example polyethylene terephthalate (PET)
A polyester sheet such as, or a flexible polyurethane sheet is preferably used. Especially 30-350k
A thickness of 50 to 200 μm having an elastic modulus of about g / cm ^2.
The transparent non-crosslinked polyurethane sheet of, which has been subjected to antioxidation treatment so as not to turn yellow, has excellent flexibility and appropriate flexibility, and therefore, when it is applied to the skin of the flexion part of the human body, It does not easily peel off from the skin by following the movement well, and it does not turn yellow, so there is a sense of cleanliness.
It is extremely preferable as the base sheet 1.

The conductive layer 1a is preferably formed of a non-corrosive conductive material, and is preferably formed of, for example, resin paint, film, ink or the like mixed with carbon powder or graphite powder. This conductive layer 1a is the base sheet 1
May be formed on the entire lower surface or may be formed in a desired pattern shape, but in any case, it is practically necessary to have a surface resistance of 500Ω or less, particularly 5 to 50Ω.
The conductive layer 1a having a surface resistance of a certain degree is preferable.

Into the terminal insertion hole 1b of the base sheet 1, a convex terminal 2 having a flange portion 2a formed at the lower end is inserted from below, and a substantially spherical terminal head 2b is provided above the base sheet 1. It is protruding. The flange 2a at the lower end of the terminal is engaged with and electrically connected to the conductive layer 1a around the terminal insertion hole 1b, and is attached so that the convex terminal 2 does not come out upward from the terminal insertion hole 1b. . This convex terminal 2 may be made of metal or conductive non-metal, but in practical use,
It is necessary to have a small electric resistance of 1Ω or less.
The shape of the head 2b of the convex terminal 2 does not have to be substantially spherical, but if it is substantially spherical, it becomes easier to insert the convex terminal 2 into the terminal insertion hole 1b, and a conductor cord for a low-frequency treatment device or the like. The plug connection to the connector at the tip is also easy.

On the lower surface of the terminal mounting portion of the base sheet 1,
A non-adhesive layer 3 having a circular planar shape is adhered with an adhesive or the like, and a conductive adhesive layer 4 is adhered to the entire lower surface of the base sheet 1 excluding the terminal attachment portion. Therefore, the non-adhesive layer 3 is surrounded by the conductive adhesive layer 4, and the boundary line L between the two is annular and non-linear. Then, a release film 5 is superposed on the lower surfaces of the non-adhesive layer 3 and the conductive adhesive layer 4, if necessary.

The non-adhesive layer 3 is made of an electrically insulating soft synthetic resin foam, a soft synthetic resin film, a non-woven fabric, a woven fabric, or a laminate of these.
The bottom surface of the convex terminal 2 is completely covered with a circular shape having a larger area than the bottom surface of the convex terminal 2. Therefore, when the electrode material is attached to the human body, the bottom surface of the convex terminal 2 does not come into contact with the skin, and the non-adhesive layer 3 blocks the direct current from the convex terminal 2 to the skin. There is no physical stimulation. Further, since the contact between the convex terminal 2 and the conductive adhesive layer 4 is cut off by the non-adhesive layer 3, the convex terminal 2 is not corroded by the moisture or the ionic compound contained in the conductive adhesive layer 4. . In particular, when the non-adhesive layer 3 made of a soft synthetic resin foam is provided, even if the lower end of the convex terminal 2 slightly projects from the lower surface (conductive layer 1a) of the base sheet 1, the appearance of the soft foam makes the foam look soft. Since it can be coated flat so that it does not project upward, it has the advantage of giving a beautiful appearance. Although the lower surface of the non-adhesive layer 3 is recessed from the lower surface of the conductive adhesive 4 in this embodiment, the lower surfaces of both layers 3 and 4 may be flush with each other.

On the other hand, the conductive adhesive layer 4 contains a hydrogel such as polyhydroxyethyl methacrylate containing an ionic compound (eg, sodium chloride, lithium perchlorate, potassium chloride, lithium chloride, etc.), or an ionic compound. It is made of polyurethane gel or the like, and the one in which the content of the ionic compound is adjusted so that the electric resistance thereof is about 0.5 to 200 kΩ · cm is used. In particular, since polyurethane gel has good adhesiveness, it can be firmly attached to human skin, and since it does not contain monomers that irritate the skin, it does not cause skin irritation, etc. It is also colorless and transparent and has a clean feeling. Therefore, it is optimal as an adhesive for forming the conductive adhesive layer 4. Such a polyurethane gel is obtained by reacting a polyol having an alkylene oxide chain with a polyurethane polyisocyanate prepolymer having an alkylene oxide chain, or a polyurethane polyol prepolymer having an alkylene oxide chain and a polyurethane polyisocyanate prepolymer having an alkylene oxide chain. Obtained by reacting the polymer.

The thickness of the non-adhesive layer 3 and the conductive adhesive layer 4 is appropriately about 1 to 3 mm, but when the electrode material is attached to the human body, the conductive adhesive layer 4 adheres to the skin. Thus, it is desirable to make the thickness of the conductive adhesive layer 4 larger than that of the non-adhesive layer 3.

In the electrode material having the above construction, the head 2b of the convex terminal 2 protruding from the base sheet 1 is connected by inserting the connector at the tip of the conductor cord of a low frequency treatment device or the like, and the conductive adhesive layer 4 is formed. It is used by sticking to the human body with the adhesive strength of. Then, when the power of the treatment device is turned on, a low-frequency minute current supplied through the conductor cord flows from the convex terminal 2 to the human body through the conductive layer 1a and the conductive adhesive layer 4, and the low frequency of the muscle and the circulatory system. Treatment is given. At this time, since the lower end of the convex terminal 2 is covered with the non-adhesive layer 3, the direct current from the lower end of the terminal to the human body is cut off, and there is no fear of receiving unpleasant electrical stimulation due to the direct current.

After the treatment is completed, the electrode material is peeled off from the skin of the human body. However, as described above, in this electrode material, the non-adhesive layer 3 is surrounded by the conductive adhesive layer 4, and the boundary line L between them is It is circular and non-linear, not straight across the electrode material. Therefore, no matter which direction the electrode material is peeled off, the base material sheet 1 and the conductive layer 1a on the lower surface thereof are not bent at the boundary line portion, so that the electrode material may be broken even if it is repeatedly attached to and peeled from the human body. There is no.

In the electrode material of the embodiment shown in FIGS. 1 to 3, the non-adhesive layer 3 is provided only on the lower surface of the terminal mounting portion of the base material sheet 1. However, in order to facilitate the peeling of the electrode material. It is desirable that the non-adhesive layer 3 be provided in a strip shape extending from the lower surface of the terminal attachment portion of the base sheet 1 to one side edge or both side edges of the base sheet 1, or a corner edge.

4, FIG. 6, FIG. 7, and FIG. 8 are all bottom views showing an embodiment in which the non-adhesive layer 3 is extended in the shape of a strip, and FIG. 5 is an embodiment shown in FIG. It is sectional drawing of an example.

That is, in the electrode material shown in FIGS. 4 and 5, the convex terminal 2 is attached to a part of the rectangular base sheet 1 near one side (the left side in FIG. 4) and the non-adhesive layer 3 is used as a base.

The boundary line L between the non-adhesive layer 3 and the conductive adhesive layer 4 has a substantially U shape or a substantially U shape, and has a non-linear shape. The non-adhesive layer 3 may be extended to the opposite side edge (right side edge in FIG. 4) or front and rear side edges (upper and lower side edges in FIG. 4) of the base sheet 1, but in that case, the extension distance is Since the area of the non-adhesive layer 3 increases and the area of the conductive adhesive layer 4 decreases, the treatment area decreases, and the sticking strength of the electrode material decreases. Therefore, the extension distance is minimized. It is desirable to select and extend the side end (the left end in this embodiment).
The width of the non-adhesive layer 3 extending in a strip shape is 10 mm or more, preferably about 10 to 20 mm, and if there is such a width, the tip portion 3a of the non-adhesive layer 3 is formed with a fingertip as described later.
The electrode material can be easily peeled off by simply flipping up.

In the electrode material shown in FIG. 6, the convex terminal 2 is attached to the center of the rectangular base sheet 1, and the non-adhesive layer 3 is attached to the bottom surface of the terminal attachment portion at the center of the base sheet to the rear side of the base sheet 1.

The boundary line L between the non-adhesive layer 3 and the conductive adhesive layer 4 has a substantially U-shape or a substantially U-shape and is non-linear.

Further, in the electrode material of FIG. 8, the convex terminal 2 is attached to the center of the rectangular base sheet 1, and the non-adhesive layer 3 is attached to both sides of the base sheet 1 from the lower surface of the terminal attaching portion in the center of the base sheet. It is provided so as to extend in a strip shape to the end (both ends on the upper side and the lower side in the figure), and the conductive adhesive layer 4 is provided on the entire lower surface of the other part of the base sheet 1, and the non-adhesive layer 3 and The boundary line L with the conductive adhesive layer 4 is linear. The boundary line L may be formed in a substantially V shape as shown by the alternate long and short dash line, and may be non-linear.

When the non-adhesive layer 3 is provided by extending in a strip shape like the electrode material shown in FIGS. 4 to 8, the non-adhesive layer 3 is not adhered to the skin even when the electrode material is applied to human skin. , The tip portion 3a of the non-adhesive layer 3 can be flipped up with a fingertip, and the electrode material can be easily peeled in the direction of the strip-shaped non-adhesive layer, and also when the above-mentioned release film 5 is laminated. The release film 5 can be easily peeled off from the electrode material. In particular, when the thickness of the non-adhesive layer 3 is smaller than that of the conductive adhesive layer 4 as described above and the width is 10 mm or more,
Since it is easy to insert a fingertip between the tip portion 3a of the non-adhesive layer 3 and the skin, it can be easily flipped up. And
Even if the electrode material is peeled off in this way, the electrode material shown in FIGS. 4 to 7 has a boundary line L between the non-adhesive layer 3 and the conductive adhesive layer 4 that is substantially U-shaped or substantially U-shaped. Since it is not a straight line that crosses over, when the tip portion 3a of the non-adhesive layer 3 is lifted up with a fingertip as representatively shown in FIGS. 4 and 5, the conductive adhesive layer 4 has a peripheral edge as shown by a dashed line. There is no concern that the base sheet 1 or the conductive layer on the lower surface of the base sheet 1 is bent and broken at this boundary portion because the base sheet 1 is peeled off from the portion and is gradually peeled off into a substantially V shape.

On the other hand, the electrode material of FIG.
Since the boundary line L between the conductive adhesive layer 4 and the conductive adhesive layer 4 is two straight lines that cross the electrode material, when the electrode material is peeled off in the direction perpendicular to the boundary line L, the base sheet 1 and the conductive layer Is easily bent and broken, but this electrode material has a tip portion 3a of one of the non-adhesive layers 3 extended to both ends.
Is peeled off in the direction of the strip-shaped non-adhesive layer 3 with a fingertip, and therefore the direction of the boundary line L and the direction of peeling the electrode material are the same. Therefore, the boundary line L is a straight line crossing the electrode material. However, there is no fear that the base sheet 1 and the conductive layer on the lower surface thereof are bent and broken at the boundary.

In each of the electrode materials of FIGS. 4 to 8 described above, the width of the non-adhesive layer 3 extended in a strip shape is constant, but this width can be maximized at the tip portion 3a of the non-adhesive layer 3. desirable. FIG. 9 is a bottom view showing the embodiment, in which a convex terminal 2 is attached to a portion of the rectangular base sheet 1 near one end (the left end in the figure) and the non-adhesive layer 3 is attached to the base sheet 1.

And the conductive adhesive layer 4 is provided on the entire lower surface of the other part of the base material sheet 1, and the boundary line L is substantially V-shaped and non-linear. In this way, the electrode material in which the width of the non-adhesive layer 3 is maximized at the tip portion 3a is easier to turn because the fingertips easily enter between the tip portion 3a of the non-adhesive layer and the skin when the electrode material is peeled off. Can be raised. And
Compared with a non-adhesive layer 3 in the form of a strip having the same width as the tip portion 3a, the area of the conductive adhesive layer 4 is increased and the treatment area can be increased.

In the embodiment of FIG. 9, the width of the non-adhesive layer 3 is gradually expanded as it approaches the tip portion 3a.
The width of the non-adhesive layer 3 up to the tip portion 3a is constant,
