Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode for electrical input / output with respect to a living body.
The present invention relates to an electrode structure for a living body used for positively promoting cosmetics and the like so as to be applied transdermally.

[0002]

2. Description of the Related Art In recent years, attempts to electrically administer drugs through the skin have been actively conducted in some places, but it has not been popularized as a specific product by the population. In some cases, its usefulness has not been fully recognized in Japan. On the other hand, in Europe and the United States, attempts have been made actively, and in fact, its usefulness is being recognized despite its effects.

[0003] However, research on iontophoresis is continuing, and among them, printed electrodes using a printing technique which enables continuous transcutaneous energization, and other interfaces between humans and energizing devices. The elucidation of the drug is progressing, and preparations are being made for the practical implementation of transdermal medication, which is originally provided with electrical conditions that are weak and have almost no effect on the human body.

[0004]

An electrode composed of a combination of a substance containing an active ingredient such as a drug and cosmetics and a conductive member has a capability of holding the drug and cosmetics and a resistance at a contact portion. Small, does not stimulate the living body chemically,
For a long time, it is necessary to satisfy the conditions that can be energized stably in the direction of promoting medication.However, due to the limitation of the ability of existing conductive gels to hold drugs and the irritability to living bodies in long-term use, As a drug holding member for iontophoresis, there is a point that it is hardly sufficient. Therefore, although the nonwoven fabric and other sponges do not have self-adhesiveness, the interface between the living body electrode and the living body does not stimulate the living body to such an extent that the above-mentioned active ingredient can be kept in contact with the living body without difficulty for a long time. It is used as a forming member.

Further, recently, a conductive ink containing silver, silver chloride, carbon, or the like is printed on a thin sheet, and a so-called printed electrode formed as a conductive member enables current to be supplied for a long time, thereby facilitating handling. It has been proposed as a shape. Since this printed electrode is thin and flexible, it can be applied to follow the surface of a living body.However, when it is combined with the above-described porous member such as a nonwoven fabric, it has no adhesive force to each other. It was pointed out that various measures were required to apply the method to the surface of a living body, and the structure became complicated. Furthermore, when the medication is performed over a long period of time, maintaining the connection state between the two becomes more complicated, such as the necessity of using a member for strong third bonding. there were.

[0006]

SUMMARY OF THE INVENTION In view of the above, the present invention relates to a method of forming a state in which both surfaces of a conductive sheet member are sandwiched by a sheet member having a porous portion typified by a nonwoven fabric or the like, thereby connecting the both members. Is achieved, the loss resistance generated at the contact portion is kept low, and the skin electrode can be protected from the sharp blade state generated at the edge of the conductive sheet member. In addition, the present invention is applied to a scalp or the like where the face and hair are often in the way because the porous sheet itself such as a nonwoven fabric is very soft and can be abutted in a favorable condition for a living body. If vitamin C, an ionized hair restorer, etc. are used for administration, the active ingredient for the living body, such as stain removal and hair growth promotion, can sufficiently exhibit its original effect.

[0007] As the porous sheet member in the present invention, nonwoven fabric, gauze, cotton cloth, or the like is used. The sheet member in the present invention only needs to have a size at least to sandwich the conductive sheet member, and more preferably, a portion to be impregnated with an active ingredient such as a drug or cosmetic is processed so as to be thick. The above-described porous material or a member obtained by laminating a plurality of the above-described porous materials is used. The present invention may be any form as long as it is at least partially porous and sandwiches both surfaces of the conductive sheet member. More preferably, one edge portion is opened and the other edge portion is opened. Is a bag-like shape obtained by thermocompression bonding, and a state in which a pocket is provided on a side surface of a porous member. The sheet member in the present invention may have at least a porous surface at the contact surface with the skin. More preferably, the back sheet portion corresponding to the back surface, which is a portion facing the contact portion with the skin, is water-repellent. Materials that do not allow moisture to permeate (polyester, PVC, etc.) prevent unnecessary diffusion of active ingredients,
When used, it is preferably used in terms of keeping hands clean.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention may be any electrode structure formed by sandwiching a conductive sheet member between the above-mentioned sheet materials. As a more preferable state, one formed in a bag shape, one formed in a pocket shape, or
When necessary, the porous sheet member may be folded so as to sandwich the conductive sheet member, and may be fixedly formed by other fixing means such as a double-sided tape or a planar fastener. still,
Since the porous sheet member on the impregnated side preferably has a certain thickness as described above in order to impregnate an active ingredient such as a drug and cosmetics, a porous sheet member formed in a pocket shape is suitable. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to FIG. In FIG. 1, reference numeral 00 denotes an interface forming means, which is formed by processing a nonwoven fabric, gauze or the like. As shown in FIGS. 3 and 4, the interface forming means 00 is constituted by two parts, that is, a skin contacting part 01 and a pocket forming part 02 for accommodating an electrode, on the side that comes into contact with the skin. The skin contact portion 01 has a configuration in which a fibrous nonwoven fabric is housed in a bag-shaped nonwoven fabric instead of a single nonwoven fabric to increase the water retention capacity. The pocket forming portion 02 is formed by bonding the edges of one nonwoven fabric sheet in three directions with the corresponding edge portion 03 of the skin contact portion 01 by pressing or the like, and opening the other one direction. ing. Reference numeral 10 denotes a conductive member, which forms a conductive portion 12 by printing a powder of silver, silver chloride, or the like on a sheet-like support member 11 such as PET, polyester, or PVC. For electrical connection to an end of the conductive portion 12 via a lead wire 14 to an external electric output device,
A clamping type terminal (clamping terminal) 13 is detachably clamped and mounted. The conductive member 10 is used by being inserted into the opening of the pocket forming part 02 as shown in FIG. At this time, when the pinching type terminals 13 are pinched and coupled, the edge of the pocket forming portion 02 may be pinched together with the conductive member 10 or the like. FIG. 2B shows an example for explaining such a state. FIG.
In (b), the pinching type terminal 13 has conductivity, and the socket part 131 electrically connected to the electric lead wire.
And a plug portion 132 having conductivity is coupled to fix a member sandwiched therebetween. Socket part 131
And the plug part 132 are connected by a connecting part 133,
As long as the connecting portion 133 is not broken, one does not disappear. This configuration is shown in FIG. The present invention may be applied to a configuration of a connection tool or the like. Support member 11 and conductive portion 12
Are stacked, and the end portion extends so as to protrude, and a hole portion 16 penetrating the front and back is formed in a part thereof. The socket part 131 and the plug part 132 are connected via the hole part 16, and the connection
When the conductive member 10 is mechanically and electrically connected, the end of the pocket forming portion 02 is also sandwiched together with the conductive member 10 to form an interface forming means. 00 and the conductive member 10 can also be mechanically coupled. Thus, the interface forming means 00 and the conductive member 10 are not easily separated from each other, and can be easily handled at the time of use. Nipping type terminal 1
When the depth of the end portion 3 of the pocket forming portion 02 is clamped, if the depth is deep, the bonding between the interface forming means 00 and the conductive member 10 becomes strong. Therefore, the deeper the better, the meaning of the bonding is as follows. There is no particular limitation because there is a case where it is sufficient to keep the distance. Further, when the plug portion 132 and the socket portion 131 sandwich the pocket forming portion 02 deeply (dotted line portion in the figure), it is preferable that the end of the pocket forming portion 02 be locally torn. A hole through which the plug 132 penetrates may be formed. After the conductive member 10 is inserted, the surface of the skin contact portion 01 is impregnated with an active ingredient such as a cosmetic or a medicinal solution in an integrated state, and a current is applied to the affected part, face, scalp, etc. .
Although not shown, the counter electrode is in contact with the skin S in advance.

In order to prevent the conductive member 10 from easily detaching from the interface forming means 00, an adhesive layer 15 may be provided by bonding a part of the opening to make the conductive member 10 narrower. Such an adhesive layer 15
Is optional and is provided as needed. However, by making the adhesive layer detachable via a low-adhesive pressure-sensitive adhesive or the like, the usability is further improved. Since the interface forming means 00 has no particularly complicated structure and is made of an inexpensive material, it can be disposable and can be used as a general cosmetic puff. It is less irritating to the skin, and can be used repeatedly for a long period or for a long period of time, such as by replacing. In addition, in the transdermal administration of the active ingredient by energization in the present invention, it is necessary to maintain good conductivity on an electric closed circuit through the skin, but according to the present invention, ionized cosmetics, Since the porous member is merely impregnated with an active ingredient or the like such as a chemical solution, the conductivity of the active ingredient can be sufficiently reflected. Depending on the active ingredient such as a drug or the like, it is necessary to energize for a long period of time, but as described above, it can withstand long-term use for a long period of time.

The conductive member and the electric output means are of a so-called separated type in which the electric output means is connected via a lead wire. It can be realized as a device of 500 yen coin or less. According to the electric output means miniaturized in this way, these are integrated into the pocket forming portion 02.
The usability in this case is greatly improved.
