Description

  The present invention relates to an electrode pad that supplies a current to a living body such as a human body.

  Currently, an energization system for the purpose of improving blood flow is commercially available. Such an energization system includes an energizing body electrically connected to a commercial power source by a power cord, an electrode unit connected to the energizing body by an energizing cord, and a winding belt that accommodates the electrode unit. Yes. This winding belt is formed in a slender shape with vinyl leather or the like, and hook and loop fasteners are attached to both ends. Such a winding belt is formed with a pocket having one surface formed of a sponge sheet, and the electrode unit is accommodated in the pocket.

  This electrode unit is formed, for example, in a structure in which three energizing electrodes are arranged in a triangle on an insulating electrode body, and an energizing cord of the energizing body is connected to the energizing electrode. When such an electrode unit is accommodated in the pocket of the winding belt, the energized electrode comes into contact with the sponge sheet. Therefore, the sponge sheet is made to absorb water to generate conductivity, and the winding belt is wound around a human arm or the like that is a living body so that the conductive sponge sheet is in close contact. In this state, when a current is passed from the current-carrying body to the electrode unit, this current is passed through the living body from the current-carrying electrode of the electrode unit via the sponge sheet.

  In addition, although not directly related to the electrode pad of the present application, there is a proposal of a conductive pad for low frequency treatment having a three-piece structure (for example, Patent Document 1). This conductive pad is formed in a structure in which a dish-shaped resin case, a metal conductive thin plate, and a sponge plate are superposed. When this conductive pad is used, a sponge plate that has absorbed moisture is brought into close contact with the living body, and low frequency is supplied from the conductive thin plate to the living body via the sponge plate.

  In a conventional energization system, it is possible to energize a living body through a sponge sheet that absorbs water from an electrode unit housed in a pocket of a winding belt. However, when such an energization system is repeatedly used, the sponge sheet that is in close contact with the living body is inevitably soiled. Adhering the soiled sponge sheet to the living body is unhygienic and uncomfortable for the user. In order to prevent this, the winding belt is replaced, but this makes it impossible to use the energization system at low cost for a long time.

  The present invention has been made in view of the above-described problems, and provides an electrode pad that can be used hygienically and inexpensively for a long period of time.

In order to solve the above-described problems, the electrode pad of the present invention has one water-absorbing body made of a water-absorbing elastic body that comes into contact with the human body, a water-absorbing unit that is detachable from a cover unit, and the water-absorbing unit. comprising an electrode unit for supplying a current, and a said cover unit detachably attached to the belt of the separate, more the electrode unit includes an electrode body formed of an insulating material, the electrode body, which are spaced from each other And having a connection socket for supplying a current from the outside to each of the energizing electrodes, the current supply using all of the energizing electrodes for one water absorption body, The current supply using a part of the plurality of energizing electrodes is selectively performed.

Therefore, in this electrode pad, the boundary part of the plurality of energizing electrodes of the electrode body is bent more easily than the other part. Similarly, the portion of the water absorption main body corresponding to the boundary portion of the electrode main body is more easily bent than the other portions. Similarly, the cover body portion corresponding to the boundary portion of the electrode body also bends more easily than the other portions. For this reason, even when the electrode pad is pressed against the curved surface of the human body, the electrode pad bends at the boundary portion of the energized electrode and adheres closely to the curved surface of the human body.

In the electrode pad as described above, as a further invention, the water absorption unit and the cover unit are detachable by the water absorption connection mechanism provided in the water absorption unit and the cover connection mechanism provided in the cover unit. The electrode unit is held by using the water absorption connection mechanism and the cover connection mechanism.

  In the electrode pad of the present invention, since the water absorption unit, the electrode unit, and the cover unit are separable, the water absorption unit that is in close contact with the living body can be separated from the electrode unit that cannot be washed and washed or replaced. Therefore, the electrode pad can be used for a long time hygienically and inexpensively.

  In the electrode pad as described above, as a further invention, when the main part of the living body is sandwiched between the pair of electrode pads attached to the fastener belt, the fastener belt is pressed by the electrode unit positioned below the surface fastener of the cover unit. While pressing the part, the auxiliary convex part located on the back side of the energizing electrode is also pressed around the part. For this reason, an energization electrode can be stuck more closely to the surface of a living body via an elastic member.

  In the electrode pad as described above, as a further invention, the boundary part of the plurality of energizing electrodes of the electrode body is more easily bent than the other part. Similarly, the portion of the water absorption main body corresponding to the boundary portion of the electrode main body is more easily bent than the other portions. Similarly, the cover body portion corresponding to the boundary portion of the electrode body also bends more easily than the other portions. For this reason, even when the electrode pad is pressed against the curved surface of the living body, the electrode pad can be bent at the boundary portion of the energizing electrode and can be satisfactorily adhered to the curved surface of the living body. Therefore, it is possible to satisfactorily energize a portion where the surface of the living body is curved.

Although details will be described later, these three energizing electrodes 122 are in close contact with the other surface of the water absorption unit 110 and energize currents supplied from the outside.

  As shown in FIG. 1, the three pressing protrusions 124 are individually projected on the other surface of the rubber sheet 121 on the back side of each of the three energizing electrodes 122. The three connection sockets 123 extend from the three pressing protrusions 124 in the same direction, and are electrically connected to the three energizing electrodes 122 individually.

As described above, in the electrode unit 120 of the electrode pad 100 according to the present embodiment, the three connection sockets 123 are extended from the three pressing protrusions 124 in the same direction, and therefore, these connection sockets. Auxiliary convex portions 125 are provided on the outer periphery of the rubber sheet 121 so as not to interfere with each other.

  Further, in the electrode unit 120 of the electrode pad 100 of the present embodiment, three concave grooves 126 are individually formed in each of the boundary portions of the three energizing electrodes 122 on the other surface of the rubber sheet 121. . A triangular electrode hole 127 is formed in the center of the rubber sheet 121 so that these three concave grooves 126 are the apexes. Furthermore, an arc-shaped concave portion 128 is formed on the outer peripheral portion communicating with the three concave grooves 126 so as not to obstruct the connection between the male hook 112 of the water absorption unit 110 and the female hook 133 of the cover unit 130.

  In the cover unit 130 of the electrode pad 100 according to the present embodiment, the plastic sheet 131 is a synthetic resin processed to be insulative and sterilizing and mold-proofing, and a triangular shape of a Rouleau that is intermediate between a triangle and a circle. The electrode unit 120 is held in the water absorption unit 110. The hook sheets 132 of the three hook-and-loop fasteners are attached to the other side on the other side of the plastic sheet 131 with which the pressing projections 124 of the held electrode unit 120 abut. As shown, the separate fastener belt 300 is detachably attached to the inner surface of the loop fastener 310 of the surface fastener.

  Further, as shown in FIG. 1, on one surface of the plastic sheet 131, three female hooks 133 that are individually removably connected to the three male hooks 112 of the water absorption unit 110 are mounted near the center of the three sides. Has been. Three radial cover holes 134 having these three female hooks 133 as apexes are formed in the center of the plastic sheet 131.

  As described above, in the electrode unit 120, three concave grooves 126 are individually formed in each of the boundary portions of the three energizing electrodes 122 of the rubber sheet 121, and the three concave grooves 126 are apexes. A triangular electrode hole 127 is formed in the center of the rubber sheet 121 so that Further, since the arc-shaped recess 128 is formed in the outer peripheral portion communicating with the three recess grooves 126, the rubber sheet 121 is more easily formed at the boundary portion of the three energizing electrodes 122 than the other portions. Has been.

  And since the sponge sheet 111 of the water absorption unit 110 is sewn from the center to the position of the three male hooks 112 in three radial shapes, one surface and the other surface with the first sewing thread 113, the rubber sheet 121 A portion corresponding to the boundary portion is formed more easily than other portions. Further, the plastic sheet 131 of the cover unit 130 has three radial cover holes 134 with the three female hooks 133 as apexes formed at the center, and therefore corresponds to the boundary portion of the rubber sheet 121. The part is formed more easily than other parts.

  Then, as shown in FIG. 4, the electrode pad 100 having the above-described structure is formed as a part of the energization system 10 at a desired position on the inner surface of one fastener belt 300 formed of a loop sheet 310 of a surface fastener. A pair is detachably attached by a hook sheet 132 of the cover unit 130. Since the fastener belt 300 has a hook sheet 320 attached to one end of the outer surface, the outer hook sheet 320 is detachably connected to the loop sheet 310 on the inner surface.

  The energization system 10 of the present embodiment includes an energization body 200 that is separate from the electrode pad 100 and the fastener belt 300, and a power cord 220 that is electrically connected to a commercial power source is connected to the energization body 200. ing. Furthermore, the energization body 200 is also connected with an energization cord 230 connected to the electrode pad 100, and the energization cord 230 is bifurcated so that it can be individually connected to each of the pair of electrode pads 100. . Further, the bifurcated portion is branched into three branches so that the three connection sockets 123 of the electrode pad 100 can be individually connected, and six connection connectors 231 are individually attached to each of them. Yes.

  In the configuration as described above, as shown in FIGS. 1 and 2, the electrode pad 100 of the present embodiment has the water absorption unit 110 superposed on the electrode unit 120 and the cover unit 130, and the three cover units 130. The female hooks 133 are individually connected to the three male hooks 112 of the water absorption unit 110 to hold the electrode unit 120.

  When the energization system 10 of the present embodiment is used, the energization cord 230 of the energization main body 200 in which the power cord 220 is connected to the commercial power supply is connected to the pair of electrode pads 100. In that case, the water absorption unit 110 is made conductive by absorbing the water absorption unit 110. And the electrode unit 120 is hold | maintained by the cover unit 130 in the water absorption unit 110 which became conductive in this way, and the electrode pad 100 is constructed | assembled.

  Since two of the three connection sockets 123 of the electrode unit 120 of the electrode pad 100 constructed in this way are located on the outer peripheral portion, the connection connectors 231 of the energization cord 230 are individually connected as they are. On the other hand, since one of the three connection sockets 123 of the electrode pad 100 is located at the center, the connection connector 231 of the energization cord 230 is connected via the cover hole 134 at the center of the cover unit 130.

  As shown in FIG. 4, the pair of electrode pads 100 to which the energization cords 230 are connected as described above are attached to one fastener belt 300. At this time, the inner surface of the fastener belt 300 is formed of the loop fastener 310 of the hook-and-loop fastener, and the hook unit 132 of the hook-and-loop fastener is attached to the cover unit 130 of the electrode pad 100. It is detachably mounted at a desired position.

  However, in the energization system 10 of the present embodiment, as shown in FIG. 5, a human arm HR or the like that is a living body is sandwiched between the pair of electrode pads 100, so that the pair of electrode pads is used as shown in FIG. 4. 100 is mounted symmetrically at an appropriate position on the fastener belt 300. In this state, as shown in FIG. 5, the fastener belt 300 is wound around the arm portion HR or the like, and the arm portion HR or the like is sandwiched between the pair of electrode pads 100.

  Thus, when the energizing body 200 is operated, a current is energized from one of the pair of electrode pads 100 to the other, and this current energizes the arm portion HR and the like. When the current is applied to the arm part HR or the like in this way, it is expected that the living body such as improvement of blood flow in the arm part HR is favorably affected. At this time, energization may be executed with all of the three energization electrodes 122 or may be executed with only a part.

  In the energization system 10 of the present embodiment, as described above, the electrode pad 100 includes the water absorption unit 110, the electrode unit 120, and the cover unit 130 that are separable. For this reason, the water absorption unit 110 that is absorbed and is in close contact with the living body can be separated from the expensive electrode unit 120 that cannot be washed and can be washed or replaced. Therefore, the electrode pad 100 of the energization system 10 can be used for a long time at low cost in a sanitary manner.

  Furthermore, in the energization system 10 of the present embodiment, the electrode pad 100 can be mounted at a desired position of the fastener belt 300 by the hook sheet 132 of the surface fastener of the cover unit 130. For this reason, desired positions, such as a human body's arm part HR and a leg part, can be pinched | interposed with a pair of electrode pad 100. FIG.

  In addition, in the energization system 10 of the present embodiment, the hook unit 132 of the hook-and-loop fastener is attached to the cover unit 130 of the electrode pad 100, and the inner surface of the fastener belt 300 is formed of the loop sheet 310 of the hook-and-loop fastener. For this reason, since the inner surface of the fastener belt 300 that is in close contact with the living body is formed of the loop sheet 310 instead of the hook sheet 132, it is possible to prevent the living body from being uncomfortable due to the close contact of the fastener belt 300.

  Further, in the energization system 10 of the present embodiment, a pressing convex portion 124 is projected on the back side of the energization electrode 122 of the electrode unit 120 of the electrode pad 100. Accordingly, when the main part of the living body is sandwiched between the pair of electrode pads 100 attached to the fastener belt 300, the fastener belt 300 presses the pressing convex portion 124 of the electrode unit 120 located under the surface fastener of the cover unit 130. For this reason, the energizing electrode 122 can be satisfactorily adhered to the surface of the living body through the elastic member.

  In particular, in the energization system 10 of the present embodiment, a hook sheet 132 of a hook-and-loop fastener is attached to the cover unit 130 at a position where the pressing convex portion 124 of the electrode unit 120 abuts. Therefore, when the main part of the living body is sandwiched between the pair of electrode pads 100 attached to the fastener belt 300, the fastener belt 300 reliably presses the pressing protrusion 124 of the electrode unit 120 located under the surface fastener of the cover unit 130. To do. For this reason, when the electrode pad 100 is attached to the fastener belt 300 and brought into close contact with the living body, the energizing electrode 122 can be brought into better contact with the surface of the living body via the water absorption unit 110.

  In addition, in the energization system 10 of the present embodiment, the auxiliary convex portion 125 protrudes around the pressing convex portion 124 on the other surface of the rubber sheet 121 on the back side of the energizing electrode 122 of the electrode unit 120. Accordingly, when the main part of the living body is sandwiched between the pair of electrode pads 100 attached to the fastener belt 300, the fastener belt 300 presses the pressing convex portion 124 of the electrode unit 120 located below the surface fastener of the cover unit 130. In addition, the auxiliary convex portion 125 located on the back side of the energizing electrode 122 is also pressed. For this reason, the energizing electrode 122 can be more closely attached to the surface of the living body through the elastic member.

  In particular, in the energization system 10 of the present embodiment, two protrusions are provided around one pressing protrusion 124. Therefore, when the main part of the living body is sandwiched between the pair of electrode pads 100 attached to the fastener belt 300, the fastener belt 300 presses one pressing convex portion 124 and two auxiliary convex portions 125. For this reason, the energizing electrode 122 can be stably pressed by so-called three-point support.

  In addition, three conductive electrodes 122 are arranged in a triangle on the electrode pad 100. For this reason, the three current-carrying electrodes 122 can be stably unattached to the surface of the living body via the water absorption unit 110 in a so-called three-point support state. Furthermore, when a current is passed through the energizing electrode 122 while holding a main part of the living body between the pair of electrode pads 100 attached to the fastener belt 300, the current can be energized through all three pairs of energizing electrodes 122. In addition, a current can be passed through a part of the three pairs of energizing electrodes 122.

  In the energization system 10 of the present embodiment, three concave grooves 126 are individually formed in each of the boundary portions of the three energizing electrodes 122 of the rubber sheet 121, and these three concave grooves 126. A triangular electrode hole 127 is formed in the center of the rubber sheet 121 so as to be the apex. Further, since the arc-shaped recess 128 is formed in the outer peripheral portion communicating with the three recess grooves 126, the rubber sheet 121 is more easily formed at the boundary portion of the three energizing electrodes 122 than the other portions. Has been.

  And since the sponge sheet 111 of the water absorption unit 110 is sewn from the center to the position of the three male hooks 112 in three radial shapes, one surface and the other surface with the first sewing thread 113, the rubber sheet 121 A portion corresponding to the boundary portion is formed more easily than other portions. Further, the plastic sheet 131 of the cover unit 130 has three radial cover holes 134 with the three female hooks 133 as apexes formed at the center, and therefore corresponds to the boundary portion of the rubber sheet 121. The part is formed more easily than other parts.

  For this reason, in the energization system 10 of the present embodiment, the electrode pad 100 is easily bent at the boundary between the three energization electrodes 122, and the three energization electrodes 122 are formed on the surface of the living body having a curved surface. The whole can be pressed well. In particular, since the six auxiliary convex portions 125 are arranged on the outer peripheral side of the rubber sheet 121 with respect to the three pressing convex portions 124 of the electrode pad 100, the pair of electrode pads 100 attached to the fastener belt 300 is used. When sandwiching the main part of the living body, the three energizing electrodes 122 can be brought into good pressure contact with the surface of the living body having a curved surface.

  Moreover, the rubber sheet 121 of the electrode unit 120 has three recesses 128 formed on the outer peripheral portion in order to facilitate bending of the electrode pad 100 as described above. Three male hooks 112 and three female hooks 133 of the cover unit 130 are individually connected. For this reason, it is not necessary to enlarge the water absorption unit 110 and the cover unit 130 in order to connect via the electrode unit 120, and the whole electrode unit 120 made easy to bend is downsized.

  The electrode unit 120 has three connection sockets 123 extending from the centers of the three energization electrodes 122 in the same direction in order to facilitate the connection of the energization cords 230. For this reason, two of the three connection sockets 123 are located at the outer periphery of the electrode pad 100, but one is located at the center of the electrode pad 100. However, as described above, in order to easily bend the electrode pad 100, one cover hole 134 having three radial shapes is formed in the center of the cover unit 130. Therefore, the connection connector 231 of the energization cord 230 can be easily connected to the connection socket 123 located at the center of the electrode pad 100 using the cover hole 134.

  Furthermore, in order to make the electrode pad 100 easy to bend as described above, the water absorbing unit 110 has three radial shapes from the center of the sponge sheet 111 to the positions of the three male hooks 112, one side and the other side being first. The sewing thread 113 is used for sewing. For this reason, it is possible to prevent the flexible sponge sheet 111 from being unnecessarily extended by the first sewing thread 113 that cannot be extended, and the durability of the water absorption unit 110 is improved. In particular, since the outer peripheral portion of the sponge sheet 111 is also sewn with the second sewing thread 114 that cannot be stretched, the durability of the water absorbing unit 110 is further improved.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, the above embodiment illustrates that the electrode pad 100 is provided with the three energizing electrodes 122. However, the number of conducting electrodes 122 provided in the electrode pad 100 may be two or less, or four or more (not shown).

  In the above embodiment, the male hook 112 is attached to the water absorption unit 110 of the electrode pad 100 and the female hook 133 is attached to the cover unit 130. However, the female hook 133 may be attached to the water absorption unit 110 and the male hook 112 may be attached to the cover unit 130, or the water absorption unit 110 and the cover unit 130 may be connected by a hook-and-loop fastener (not shown).

  Furthermore, in the said form, in order to make the bending of the electrode pad 100 easy, it illustrated that the concave groove 126 was formed in three radial shapes on the other surface of the rubber sheet 121 of the electrode unit 120. However, such a concave groove 126 may be formed on one surface of the rubber sheet 121, or may be formed on both one surface and the other surface. Further, instead of the concave groove 126, a plurality of continuous small holes or slits may be formed in three radial shapes.

  Similarly, in the above embodiment, in order to facilitate the bending of the electrode pad 100, it has been exemplified that three cover holes 134 having three radial shapes are formed at the center of the cover unit 130. However, the cover hole 134 may be formed by a central round hole and three slits, or may be formed by a central round hole and a plurality of small holes continuous in three directions (not shown). )

  Moreover, in the said form, it illustrated that the three connection sockets 123 each electrically connected to the three electricity supply electrodes 122 of the electrode unit 120 were extended in the same direction. However, such a plurality of connection sockets 123 may be formed in a radial pattern (not shown). In this case, the cover hole 134 at the center of the cover unit 130 is not essential, and may be formed by, for example, three radial slits.

  Furthermore, in the said form, it illustrated that the two auxiliary convex parts 125 protruded around the press convex part 124 of the electrode unit 120. As shown in FIG. However, the number of such auxiliary convex portions 125 may be one, or three or more (not shown). Moreover, the auxiliary convex part may be formed in one circular arc shape etc. (not shown).

  Further, in the above embodiment, only the case where the energization system 10 energizes the living body such as the arm portion HR from the pair of electrode pads 100 is illustrated. However, an ultrashort wave, a low frequency, or the like may be applied to the living body from the electrode pad of such an energization system.
