[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wound dressing for skin, such as a bandage, gauze, flannel or bandage, which is used by directly applying a sterilized contact member to the wound for treating the wound. It concerns materials.

[0002]

2. Description of the Related Art It has been already known that electrical stimulation using a minute electric current is effective not only for activating cells in a living body and promoting fracture healing, but also for tissues other than bone. (For example, Masami Akai: Effect of electrical stimulation on living body, Journal of Japan Orthopedic Society, Vol. 67, No. 4, 1993.
Year). However, no suitable proposal has hitherto been made on how to easily and effectively utilize this for the healing of tissues of a living body.

[0003]

The surface of the skin of a living body is
It has a high electrical insulation, but its inner side is close to that of salt water, so it has excellent conductivity. Therefore, when the skin is traumatized, when electrical stimulation is applied from outside with a small current, the electrical stimulation effectively acts on the tissue of the wound, activating the cells of the tissue, Effectively promotes healing. In addition, with respect to bacteria, unlike the cells of the living body, an appropriate minute current has a bactericidal effect.

A fundamental technical problem of the present invention is to utilize the fact that the wound cells of the living body can be effectively activated by the above-mentioned electrical stimulation, so that the contact member to the skin is suitable for the treatment of the wound by the electrical stimulation. It is intended to provide a wound dressing for skin in the constructed bandages, bandages and the like. A further specific technical problem of the present invention is to apply the electrical stimulation to the tissue of a wound simply by directly applying the member for abutting against the skin in a bandage or bandage used for treating a skin wound to the wound. It is an object of the present invention to provide a wound dressing for skin which is configured as described above and is capable of extremely easily activating the wound cells by electrical stimulation and simultaneously having a bactericidal action.

[0005]

A wound dressing for skin of the present invention for solving the above-mentioned problems is to apply a minute electric current to a wound contact surface of a contact member directly applied to the wound. It is characterized in that electrodes for flowing are provided and those electrodes are connected to an electromotive force generation source for electrical stimulation. The wound dressing for skin having such a configuration is such that the contact member provided with the electrode is brought into contact with the wound on the skin with a bandage or a bandage, and preferably the positive electrode and the negative electrode of the electrode are provided near both ends of the wound. Are positioned and brought into contact with each other, whereby electrical stimulation is efficiently applied from the electromotive force generation source to the tissue of the electrically conductive wound portion through the electrodes, and the cells in that portion are activated. , Wound healing is promoted, and a bactericidal action is also given.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 1 and 2, a wound dressing for skin according to the present invention has a wound 1 of a living body 10.
The contact member 1 is used by directly contacting the contact member 1. The contact member 1 is harmless even when it comes into contact with a completely sterilized gauze, cotton cloth, flannel, or other wound 11 of the living body 10, and is suitable for protecting the wound or diseased part and preventing bacterial invasion. A sheet-shaped appropriate material may be used, and a chemical solution such as a disinfectant may be permeated if necessary. The abutting member 1 may be attached to a part of a bandage or bandage (not shown), or may be formed as a part of the bandage, and is used independently. It does not matter even if it is a thing.

The contact surface 1a of the contact member 1 for contacting the wound 11 is provided with a plurality of electrodes 2a, 2b connected to the electromotive force generating source 3 for supplying a minute current to the wound 11. The electrode of is the electrode 2a connected to the positive electrode 3a of the electromotive force generating source 3 and the negative electrode 3b of the electromotive force generating source 3.
The electrodes 2b connected to the electrodes are arranged at a certain distance from each other according to the size of the wound, or, as shown in FIG.
They may be arranged alternately in parallel lines, or they may be dispersed at multiple points. Since these electrodes are arranged to allow a minute electric current to flow to the wound, they can be arranged in any other arbitrary arrangement within the range that meets the purpose.

The linear electrodes 2a and 2b are formed by, for example, directly adhering or printing a conductive flexible electrode material on the contact surface 1a of the contact member 1 or contacting the contact surface 1a. It can be formed by an arbitrary means such as weaving a flexible linear electrode material into the woven fabric forming the member 1 or applying a conductive paste-like material that does not cause damage to scratches. When the electrodes 2a and 2b are dot-shaped or close thereto, it is not necessary for the electrode material to have particular flexibility, and the electrodes 2a and 2b can be formed of an arbitrary conductive material. Further, the electrodes 2a and 2b do not need to be fixed to the contact surface 1a of the contact member 1, and an electrode formed of aluminum foil or the like is provided from the contact surface 1a via a short flexible conductive member. And the electrodes are attached to both sides of the wound 11 and other suitable positions, and then sterilized.
It is also possible to cover the wound with.

The electrodes 2a and 2b are connected to an electromotive force generating source 3 for supplying a minute current for electrical stimulation thereto. The electromotive force generating source 3 is a photoreactive electromotive force as shown in FIG. Not only materials (for example, solar cells, PLZT, etc.), but also force-responsive electromotive force materials that generate electromotive force due to the action of force (stretching, compression-tension, shear, twist, etc.), chemical reaction initiation that causes electromotive force by a chemical reaction A power material or the like can be used, and various commonly used small batteries can also be used. These are contact members 1
However, if possible, it can be configured as a separate body from the contact member.

When the above photoreactive electromotive force material is used as the electromotive force generation source 3, generally, as shown in FIG. 1, the electromotive force is generated on the back surface 1b of the contact member 1 made of sterilized gauze or the like. The electric power material is fixed by adhesion or other means, and a conductive wire is drawn out from the output terminal in an appropriate direction to form the electrode 2 on the contact surface 1a side.
Although connected to a and 2b, this conductive line can be configured to have flexibility and stretchability by printing a conductive material. Further, the electrode may be directly projected from the photoreactive electromotive force material on the back surface 1b side of the contact member 1 to the contact surface 1a side. Further, the photo-reactive electromotive force material can be assembled so that it can be exposed on the surface of a bandage or a bandage, and can be connected to the electrodes 2a and 2b by an appropriate conductive wire. In this case, the flexible conductive material is used. The material can also be folded into a bandage. As such a photo-reactive electromotive force material, one that has a very small size but can generate a necessary electromotive force at a level of light of a fluorescent lamp has already been developed. Can be used without.

When a force-responsive electromotive force material that produces electromotive force due to the action of the force is used, the force-responsive electromotive force material is directly attached to the contact member 1 or a flexible insulating material such as thin vinyl. It is also possible to print it on top and attach it to the abutment member 1 together with its insulating material, and then attach them to a bandage or bandage. In this force-responsive electromotive force material, the part to which it is attached is deformed along with the daily movement of a living body, and the force-responsive electromotive force material is acted upon by forces such as expansion and contraction, compression-tension, shear, and twist. This is advantageous when power is generated.

As the chemical reaction electromotive force material, for example, sterilized gauze or the like is added with the first electromotive force material in advance by means such as impregnation, insertion, or printing to use the wound dressing for skin. For example, it is common to generate an electromotive force by adding a second electromotive force material such as physiological saline, which is harmless to the living body. Further, as the electromotive force generation source 3, various commonly used batteries can be used, and in this case, the output terminal of the battery accommodating portion is connected to the electrode by an arbitrary means. A controller may be provided between the electromotive force generation source 3 and the electrode to adjust a minute current applied to the wound of the living body, if necessary.

In the wound dressing for skin having such a structure, the contact member 1 provided with the electrodes 2a and 2b is brought into contact with the wound of the skin by a bandage or a bandage, and preferably near both ends of the wound 11. The positive electrode and the negative electrode of the electrode may be positioned and brought into contact with each other so that the electrostimulation from the electromotive force generation source 3 through the electrodes 2a and 2b is effective for the tissue of the wound portion having excellent conductivity. The wound healing is promoted by the activation of the cells in that area. In addition, since an appropriate minute current has a sterilizing effect, a sterilizing action is also added.

[0014]

EFFECTS OF THE INVENTION According to the wound dressing material for skin of the present invention described in detail above, it is possible to directly apply electrical stimulation to the wound to promote healing by activating wound cells, and yet to prevent the wound on the skin. Since the member for abutting against the skin in the bandage or bandage used for the treatment of is applied to the wound tissue just by directly applying it to the wound, the electrical stimulation can be performed very easily. The wound cells can be activated and, at the same time, a bactericidal action can be obtained.
