(An example of the form that the electrical stimulator can take)
[1] One form of the electrical stimulation device according to the present invention is a detection unit that outputs a signal reflecting the operation of a target part of the body, and an electrode part that applies electrical stimulation to the target part based on the signal of the detection part The detection unit and the electrode unit are integrally configured.

  The detection unit and the electrode unit function when electric power is supplied to each other. For this reason, the harness which supplies the electric power of a power supply is connected to a detection part and an electrode part, for example. On the other hand, when the detection unit and the electrode unit are provided at positions separated from each other, for example, a harness that supplies power to the detection unit and a harness that supplies power to the electrode unit are required.

  According to the electrical stimulation device, since the detection unit and the electrode unit are integrally configured, the harness that supplies power to the detection unit and the electrode unit is combined into one. For this reason, compared with the case where a detection part and an electrode part are provided in the position which left | separated, it can contribute to reducing a number of parts.

  [2] According to an example of the electrical stimulation device, a connector that can be connected to a harness that supplies power from a power source, is electrically connected to the electrode unit, and a case that houses the detection unit and the connector; Is further provided.

  According to the electrical stimulation device, the detection unit and the connector are accommodated in one case. For this reason, compared with the case where the case which accommodates a connector and the case which accommodates a detection part are provided separately, the number of parts is further reduced.

  [3] According to an example of the electrical stimulation device, the case has an elongated shape capable of defining a longitudinal direction and a lateral direction, and the longitudinal direction is arranged along the longitudinal direction of the target portion.

  When the case is placed so that the longitudinal direction of the case is along the circumferential direction of the target part, the user who exercises using the electrostimulator may feel uncomfortable with the fit between the target part and the case, and hinder movement There is a risk of becoming. On the other hand, according to the electrical stimulation device, since the case is arranged so that the longitudinal direction of the case is along the longitudinal direction of the target part, it is difficult for the fit between the target part and the case to feel uncomfortable. For this reason, a possibility that the exercise | movement which a user implements may be prevented is reduced.

[4] According to an example of the electrical stimulation device, the detection unit and the electrode unit are separable from each other.
For example, when dust or the like adheres to the electrode portion, the electrical stimulation applied to the target portion is reduced, and therefore it is preferable to periodically maintain the electrode portion. According to the electrical stimulation device, since the electrode unit and the detection unit can be separated, maintenance of the electrode unit is easy.

  [5] According to an example of the electrical stimulation device, the electrode unit includes a conductor pair for applying electrical stimulation to the target site, a first surface to which the conductor pair is attached, and a detector unit to which the detection unit is attached. A sheet having two surfaces.

  When a detection part is attached to the 1st surface of the sheet | seat in which a conductor pair is attached, there exists a possibility that the fitting feeling of a target site | part and a conductor pair may be prevented by the detection part. On the other hand, according to the electrical stimulation device, since the detection unit is attached as described in [5], the possibility that the fit between the target part and the conductor pair is hindered by the detection unit is reduced.

  [6] According to an example of the electrical stimulation device, the sheet includes a conductor arrangement portion having a shape corresponding to the arrangement of the conductor pairs, the electrode portion has conductivity, and the conductor arrangement A conductive gel sandwiching the conductor pair between the conductive portion and the conductive gel, the conductive gel having a similar shape to the conductor placement portion, and attached to the conductor placement portion so that the centers thereof coincide with each other. It has an area substantially the same as the area of the child arrangement part or an area larger than the area of the conductor arrangement part.

  When the edge of the conductor placement portion is in direct contact with the target site, the user may feel uncomfortable. On the other hand, according to the electrical stimulation device, since the area of the conductive gel is substantially the same as the area of the conductor placement portion or wider than the area of the conductor placement portion, the edge of the conductor placement portion contacts the target site. This is easily disturbed by the conductive gel. For this reason, it is difficult for the user to feel uncomfortable.

  [7] According to an example of the electrical stimulation device, the electrode unit includes a plurality of the conductor pairs, and the plurality of conductor pairs include a first conductor pair and a second conductor pair, The sheet has a first conductor arrangement portion having a shape corresponding to the arrangement of the first conductor pairs, and a second conductor arrangement portion having a shape corresponding to the arrangement of the second conductor pairs. , And a connecting portion that connects the first conductor placement portion and the second conductor placement portion, the first conductor placement portion supports the first conductor pair, and the second conductor placement portion. The conductor arrangement portion supports the second conductor pair, and the first conductor pair and the second conductor pair are an array of a pair of conductors constituting the first conductor pair. And the dimension of the connecting portion in the arrangement direction of the pair of conductors is the first conductor arrangement. Parts and shorter than the dimension of the second Shirubeko placement portion.

  According to the electrical stimulation device, since the dimension of the connecting portion of the sheet is set as described in [7], the target portion is compared with the case where the dimension of the sheet in the arrangement direction of the pair of conductors is uniform. The adhesion of the electrode part with respect to is improved.

  Moreover, according to the said electrical stimulation apparatus, the space | interval is opened between the 1st conductor arrangement | positioning part and the 2nd conductor arrangement | positioning part from a viewpoint of improving a training effect. That is, a seat connection portion is provided to enhance the training effect. For this reason, when a detection part is arrange | positioned on the back surface of the connection part of a sheet | seat, for example, space can be utilized efficiently.

[8] According to an example of the electrical stimulation device, the sheet has flexibility.
According to the electrical stimulation device, the electrode part can easily fit the target part. For this reason, the adhesiveness of the electrode part with respect to an object site | part is further improved.

[9] According to an example of the electrical stimulation device, the electrical stimulation apparatus further includes a supporter that can be attached to the target site and to which the detection unit and the electrode unit are attached.
According to the electrical stimulation device, since the detection unit and the electrode unit are fixed to the target site by attaching the supporter to the target site, the detection unit and the electrode unit are unlikely to be detached from the target site.

  [10] According to an example of the electrical stimulation device, the device includes a plurality of the electrode units, and the plurality of electrode units include a first electrode unit and a second electrode unit, and the first electrode unit and the first electrode unit At least one of the two electrode portions can be adjusted with respect to the supporter in the circumferential direction of the target portion.

  The thickness of the target portion varies depending on the user who uses the electrical stimulation device. For this reason, when the supporter is attached to the target part, at least one of the first electrode part and the second electrode part may not be attached to an appropriate position of the target part. On the other hand, according to the electrical stimulation device, since the position of at least one of the first electrode part and the second electrode part can be adjusted for each user, each electrode part is easily attached to an appropriate position of the target part.

  [11] According to an example of the electrical stimulation device, the supporter includes a first mark for teaching information related to a thickness of the target part, and the first electrode unit and the second electrode on the supporter. And a second mark that teaches a position corresponding to the first mark on the supporter.

  The user who uses the electrical stimulation device determines the position of each electrode unit with respect to the supporter, for example, according to the following procedure. First, a supporter is attached to the target part, and information indicated by the first mark is confirmed. Next, the supporter is removed from the target part, and each electrode part is attached to a position corresponding to the first mark on the supporter while referring to the second mark. By the above procedure, each electrode part is attached to an appropriate position of the target part. For this reason, compared with the case where a user determines the position of each electrode part based on own sense, each electrode part is easily attached to the appropriate position of a target part.

  [12] According to an example of the electrical stimulation device, a first harness that supplies power from a power source to one of the first electrode part and the second electrode part, the first electrode part, and the first electrode part And a second harness for supplying electric power from one of the two electrode portions to the other.

  When a harness that supplies power to the first electrode part and a harness that supplies power to the second electrode part are provided, two long harnesses are required. On the other hand, according to the electrical stimulation device, the power of the power source is supplied to one of the first electrode portion and the second electrode portion via the first harness, and the first electrode portion via the second harness. Electric power is supplied to the other of the second electrode portions. The first harness has substantially the same length as the two long harnesses, whereas the second harness is shorter than the first harness. For this reason, compared with the case where two long harnesses are provided, the structure of the electrical stimulation device is simplified.

[13] According to an example of the electrical stimulation device, the supporter includes a housing portion that houses at least one of the first harness and the second harness.
When the supporter is attached to the target part, for example, a part of the first harness and the whole of the second harness exist between the supporter and the target part. For this reason, there exists a possibility that a user may feel discomfort because each harness contacts a target part directly. On the other hand, according to the electrical stimulation device, since at least one of the first harness and the second harness is accommodated in the accommodating portion, the harness accommodated in the accommodating portion does not directly contact the target site. For this reason, the possibility that the user feels uncomfortable is reduced.

  [14] According to an example of the electrical stimulation device, the first electrode portion is disposed at a position on the supporter that faces the quadriceps muscle when the supporter is mounted on the thigh as the target site. The conductor pairs constituting the first electrode portion are attached to the sheet such that the arrangement direction thereof is along the circumferential direction of the target portion.

  The inventor of the present application examined a site to which electrical stimulation is applied to improve the quadriceps training effect. As a result, it was confirmed that the training effect of the quadriceps muscle is improved if electrical stimulation can be applied across the rectus femoris, lateral vastus and medial vastus. Based on the result of this study, the electrical stimulation device sets the arrangement direction of the conductor pairs constituting the first electrode portion along the circumferential direction of the target site. Thereby, since electrical stimulation is applied so as to straddle the rectus femoris, lateral vastus muscles, and medial vastus muscles, the training effect of the quadriceps muscles is enhanced.

  [15] According to an example of the electrical stimulation device, the second electrode portion is disposed at a position on the supporter that faces the hamstring when the supporter is attached to the thigh that is the target part, The conductor pairs constituting the second electrode portion are attached to the sheet such that the arrangement direction thereof is along the longitudinal direction of the target portion.

  The inventor of the present application examined a site to which electrical stimulation is applied in order to improve the training effect of the hamstring. As a result, it was confirmed that the training effect of the hamstring is improved if electrical stimulation can be applied along the two hamstrings. Based on the result of this study, the electrical stimulation device sets the arrangement direction of the conductor pairs constituting the second electrode portion along the longitudinal direction of the target site. Thereby, since electrical stimulation is given along two hamstrings, the training effect of a hamstring is improved.

  [16] According to an example of the electrical stimulation device, the supporter faces a center mark for alignment with the center of the thigh as the target site, and the center mark when the supporter is attached to the thigh. With a constricted part.

  When the supporter is attached to the thigh, or after the supporter is attached to the thigh, when the knee joint is bent, the supporter and the back of the knee may come into contact with each other, and the user may feel uncomfortable. On the other hand, according to the electrical stimulation device, since the supporter has a constricted portion as described in [16], it is difficult for the supporter and the back of the knee to come into contact with each other, and the possibility that the user feels uncomfortable is reduced.

  [17] According to an example of the electrical stimulation device, the apparatus includes a plurality of supporters, and the plurality of supporters are a first supporter attached to one of the right half body and the left half body of the body and the right half body and the left half body of the body. A second supporter attached to the other of the first supporter, the first supporter and the second supporter each including the electrode unit, and the at least one of the first supporter and the electrode unit attached thereto, In addition, at least one of the second supporter and the electrode portion attached to the second supporter includes a corresponding mark for teaching the corresponding right or left body.

  For example, after confirming the corresponding mark, the user who uses the electrical stimulation apparatus wears a supporter corresponding to the target part of the right half body and wears a supporter corresponding to the target part of the left half body. For this reason, the possibility that the opposite supporters are attached to the target parts of the right and left bodies is reduced.

  [18] According to an example of the electrical stimulation device, the first supporter and the electrode portions attached to the first supporter are separable from each other, each having the corresponding mark, and the second supporter The supporter and the electrode part attached to the second supporter are separable from each other, and each has the corresponding mark.

  The user who uses the electrical stimulation apparatus attaches the electrode part corresponding to the first supporter and the electrode part corresponding to the second supporter after confirming the corresponding mark, for example. For this reason, a possibility that the electrode part opposite to a 1st supporter and a 2nd supporter may be attached respectively is reduced.

[19] According to an example of the electrical stimulation device, the protective sheet further includes a protective sheet that protects the surface of the conductor arrangement part, and the protective sheet has higher rigidity than the electrode part.
According to the electrical stimulation device, when the protective sheet is not used, the protective sheet is attached to the surface of the conductor placement portion, so that it is difficult for dust or the like to adhere to the conductive gel or the like. In addition, since the protective sheet has higher rigidity than the electrode part, the user can easily feel uncomfortable when the supporter is attached to the target part in a state where the protective sheet is attached to the conductor arrangement part. For this reason, a possibility that the said electrical stimulation apparatus may be used with the protective sheet attached to the conductor arrangement | positioning part is reduced.

  [20] According to an example of the electrical stimulation device, the electrode unit attached to the first supporter, and a harness for supplying power from the power source to the electrode unit attached to the second supporter, The harness includes a first line connected to the electrode part attached to the first supporter, a second line connected to the electrode part attached to the second supporter, and the first wire. And a common line connected to the second line, and at least one of the first line and the second line is extendable.

  When exercising using an electrical stimulator, the distance between the first supporter and the second supporter may be increased depending on the content of the exercise performed by the user, and the harness may be pulled strongly. For this reason, deterioration of the harness is promoted. On the other hand, according to the electrical stimulation device, a part of the harness that connects one electrode part and the other electrode part expands and contracts, so that the distance between the first supporter and the second supporter is increased. But the harness is hard to be pulled. For this reason, it is difficult to promote deterioration of the harness.

  [21] According to an example of the electrical stimulation device, the common line can be connected to a controller that controls the electrode unit, and the harness is closer to the first line and the second line in the common line. And a clip attached to at least one of the portion near the controller.

  When the user puts the supporter on the target site, the harness may feel in the way. On the other hand, according to the electrical stimulation device, since the clip is attached as described in [21], the harness can be fixed by attaching the clip to the outer jacket or the like before attaching the supporter to the target site. For this reason, when attaching a supporter to an object part, it is hard to feel a harness out of the way.

  [22] According to an example of the electrical stimulation apparatus, the electric stimulation device further includes a holding case that holds a controller that controls the electrode unit, and the holding case includes a case body that houses the controller, a loop into which a belt can be inserted, And a connecting portion that connects the case body and the loop so that the loop can swing relative to the case body with the upper portion of the case body as a fulcrum.

  A user who uses the electrical stimulation apparatus wears trousers or the like after attaching the supporter to the thigh, which is an example of the target part. In this case, for example, the belt inserted into the loop of the holding case from the outside of the pants is tightened. However, some users may feel uncomfortable with exposing the belt to the outside. On the other hand, according to the electrical stimulation device, the connection part for connecting the case body and the loop is provided in the holding case as described in [22]. For this reason, by tightening the belt and then sandwiching the trousers between the case body and the loop, the case body can be disposed outside the trousers and the belt can be disposed inside the trousers. For this reason, the belt can be fastened without exposing the belt to the outside.

According to the second mounting state, the holding case 80 is mounted by the user in the following procedure. First, the belt 90 inserted into the loop 82 of the holding case 80 is tightened. Next, the trousers 210 are worn to the waist so that the trousers 210 are sandwiched between the case body 81 and the loop 82. At this time, the coupling portion 84 of the holding case 80 is opened. Finally, the controller 100 is stored in the case body 81. According to this second mounting state, the weight of the controller 100 is supported by the connection portion 83 of the holding case 80. For this reason, the controller 100 is stably held by the holding case 80.

With reference to FIG. 2 and FIGS. 13-18, the mounting | wearing procedure of the electrical stimulation apparatus 1 is demonstrated.
The electrical stimulation device 1 is typically attached to the thigh 200 through the following procedure. In the first procedure, as shown in FIG. 18, the first clip 71 and the second clip 72 are attached to clothes such as a jacket 220. At this time, the controller 100 (see FIG. 7) is removed from the first harness 61.

  In the second procedure, as shown in FIG. 2, the first electrode unit 30 and the second electrode unit 40 are attached to the supporter 10. According to an example, the second electrode unit is arranged such that the part pointed by the adjusting part 17C of the second mark 17 coincides with the part pointed by the teaching part 17B formed below the notation “M”. 40 is attached to the supporter 10.

  In the third procedure, one supporter 10 is attached to the thigh 200 as shown in FIG. Specifically, the knee mark 18 </ b> B is aligned with the tip of the knee so that the center line 18 </ b> A is aligned with the center of the thigh 200, and the second portion 12 and the third portion are placed in the state where the first portion 11 is placed on the thigh 200. The portion 13 is wound around the thigh 200. Then, the supporter 10 is attached to the thigh 200 by adjusting the position where the hook 14A (see FIG. 2) is attached to the loop 14B so that the supporter 10 fits the thigh 200. Note that the skin of the thigh 200 to which the supporter 10 is attached is exposed.

  In the fourth procedure, information on the thickness of the thigh 200 is confirmed with reference to the first mark 16. When the teaching unit 16D of the first mark 16 indicates the range of “M” of the notation unit 16A, the second electrode unit 40 is attached to the position of “M” by the second procedure. It is suggested that the electrode portions 30 and 40 are arranged at appropriate positions on the thigh 200. That is, the 1st electrode part 30 is arrange | positioned in the position on the supporter 10 facing a quadriceps femoris muscle, and the 2nd electrode part 40 is arrange | positioned in the position on the supporter 10 facing a hamstring. For this reason, when the position of the 2nd electrode part 40 attached to the supporter 10 by the 2nd procedure and the information confirmed by the 4th procedure correspond, it transfers to the 8th procedure.

  On the other hand, as shown in FIG. 14, when the teaching unit 16D of the first mark 16 indicates the range of “S” of the notation unit 16A in the fourth procedure, the process proceeds to the fifth procedure. In the fifth procedure, the supporter 10 attached by the third procedure is removed from the thigh 200. In the sixth procedure, as shown in FIG. 15, the location pointed by the adjusting portion 17 </ b> C of the second mark 17 is located below the notation “S” of the notation portion 17 </ b> A, which is the position corresponding to the first mark 16. The position of the second electrode portion 40 with respect to the supporter 10 is adjusted so as to coincide with the location indicated by the formed teaching portion 17B. In the seventh procedure, when one supporter 10 is mounted on the thigh 200 in the same procedure as the third procedure, the electrode portions 30 and 40 are arranged at appropriate positions on the thigh 200. Then, the process proceeds to the eighth procedure.

  As shown in FIG. 16, when the teaching unit 16D of the first mark 16 indicates the “L” range of the notation unit 16A in the fourth procedure, the process proceeds to the fifth procedure. In the fifth procedure, the supporter 10 attached by the third procedure is removed from the thigh 200. In the sixth procedure, as shown in FIG. 17, the location pointed by the adjusting portion 17 </ b> C of the second mark 17 is located below the notation “L” on the notation portion 17 </ b> A where the position corresponding to the first mark 16. The position of the second electrode portion 40 with respect to the supporter 10 is adjusted so as to coincide with the location indicated by the formed teaching portion 17B. In the seventh procedure, when one supporter 10 is mounted on the thigh 200 in the same procedure as the third procedure, the electrode portions 30 and 40 are arranged at appropriate positions on the thigh 200. Then, the process proceeds to the eighth procedure.

  In the eighth procedure, the other supporter 10 is attached to the thigh 200 based on the information regarding the first mark 16 confirmed by the fourth procedure. In the ninth procedure, as shown in FIG. 18, the trousers 210 are worn so as to cover each mounted supporter 10. In the tenth procedure, the holding case 80 is mounted and the first harness 61 is connected by either the first mounting state (see FIG. 11) or the second mounting state (see FIG. 12) of the holding case 80. The controller 100 is housed in the case body 81. As described above, the electrical stimulation device 1 is attached to the thigh 200 through the first procedure to the tenth procedure.

According to the electrical stimulation device 1 of the embodiment, the following effects can be obtained.
(1) The angular velocity sensor 51 and the first electrode unit 30 function by supplying power to each other. For this reason, for example, the harness 60 that supplies power from the power source is connected to the angular velocity sensor 51 and the first electrode unit 30. On the other hand, when the angular velocity sensor 51 and the first electrode unit 30 are provided at positions separated from each other, for example, a harness that supplies electric power to the angular velocity sensor 51 and a harness that supplies electric power to the first electrode unit 30 are necessary. Become.

  According to the electrical stimulation device 1, since the angular velocity sensor 51 and the first electrode unit 30 are integrally configured, the harness 60 that supplies power to the angular velocity sensor 51 and the first electrode unit 30 is combined into one. . For this reason, compared with the case where the angular velocity sensor 51 and the 1st electrode part 30 are provided in the position which left | separated, it can contribute to reducing a number of parts.

  When the angular velocity sensor 51 and the first electrode unit 30 are integrally configured, one arrangement of the angular velocity sensor 51 and the first electrode unit 30 on the supporter 10 is not limited by the other arrangement. For this reason, according to the electrical stimulation device 1, the angular velocity sensor 51 and the first electrode unit 30 are provided on the first portion 11 of the supporter 10. Since the first portion 11 is wound around the front side of the thigh 200, the first portion 11 is opposed to the quadriceps femoris and the operation of the thigh 200 is easily reflected. Therefore, the angular velocity sensor 51 outputs a signal that reflects the angular velocity of the thigh 200 with high accuracy, and the quadriceps muscles are efficiently trained by the first electrode unit 30.

  (2) According to the electrical stimulation device 1, the angular velocity sensor 51 and the connector 52 are accommodated in one case 50. For this reason, compared with the case where the case which accommodates the connector 52 and the case which accommodates the angular velocity sensor 51 are provided separately, the number of parts is further reduced.

  (3) When the case 50 is arranged so that the longitudinal direction of the case 50 is along the circumferential direction of the thigh 200, depending on the user who exercises using the electrical stimulation device 1, the fit between the thigh 200 and the case 50 is uncomfortable. There is a risk of disturbing exercise. On the other hand, according to the electrical stimulation device 1, the case 50 is arranged so that the longitudinal direction of the case 50 is along the longitudinal direction of the thigh 200, and thus it is difficult to feel a sense of incongruity in the fit between the thigh 200 and the case 50. For this reason, a possibility that the exercise | movement which a user implements may be prevented is reduced.

  (4) Since the electrical stimulation given to the thigh 200 decreases when, for example, dust or the like adheres, for example, the first electrode unit 30 is preferably regularly maintained. According to the electrical stimulation device 1, since the first electrode unit 30 and the angular velocity sensor 51 can be separated, the first electrode unit 30 can be easily maintained.

  (5) When the angular velocity sensor 51 is attached to the first surface 34 of the sheet 33 to which the conductor pairs 31 and 32 in the first electrode unit 30 are attached, the fit between the thigh 200 and the conductor pairs 31 and 32 is felt. The angular velocity sensor 51 may be hindered. On the other hand, according to the electrical stimulation device 1, since the angular velocity sensor 51 is attached to the second surface 37 of the seat 33, the possibility that the fit between the thigh 200 and the pair of conductors 31 and 32 is hindered by the angular velocity sensor 51 is reduced. Is done.

  (6) If the edges of the conductor placement portions 34A and 34B in the first electrode portion 30 are in direct contact with the thigh 200, the user may feel uncomfortable. On the other hand, according to the electrical stimulation device 1, since the area of the pair of conductive gels 35 is substantially the same as the area of the conductor placement portions 34A and 34B, the edges of the conductor placement portions 34A and 34B are thigh 200. Contact with the pair of conductive gels 35 is easily hindered. For this reason, it is difficult for the user to feel uncomfortable. The same effect can be obtained in the second electrode portion 40.

  (7) According to the electrical stimulation device 1, the dimension of the connection portion 34C in the arrangement direction of the pair of conductors 31A and 32A is larger than the dimensions of the first conductor arrangement portion 34A and the second conductor arrangement portion 34B. short. For this reason, the adhesiveness of the 1st electrode part 30 with respect to the thigh 200 is improved compared with the case where the dimension of the sheet | seat 33 in the sequence direction of a pair of conductor 31A, 32A is uniform.

  (8) According to the electrical stimulation device 1, the first conductor placement portion 34A and the second conductor placement portion 34B are spaced from the viewpoint of enhancing the training effect. That is, the connection portion 34C of the seat 33 is provided to enhance the training effect. On the other hand, according to the electrical stimulation device 1, the case 50 is disposed so as to pass through the back surface of the connecting portion 34C. That is, the angular velocity sensor 51 is disposed on the back surface of the connection portion 34 </ b> C of the seat 33. For this reason, space can be utilized efficiently.

  (9) According to the electrical stimulation device 1, since the sheet 33 has flexibility, the first electrode unit 30 can easily fit into the thigh 200. For this reason, the adhesiveness of the 1st electrode part 30 with respect to the thigh 200 is improved. The same effect can be obtained in the second electrode portion 40.

  (10) According to the electrical stimulation device 1, the angular velocity sensor 51 and the electrode portions 30, 40 are fixed to the thigh 200 by attaching the supporter 10 to the thigh 200. 40 is hard to come off from the thigh 200.

  (11) The thickness of the thigh 200 varies depending on the user who uses the electrical stimulation device. For this reason, when the supporter is attached to the thigh 200, at least one of the first electrode unit 30 and the second electrode unit 40 may not be attached to an appropriate position of the thigh 200. On the other hand, according to the electrical stimulation device 1, since the second adjustment unit 15 for adjusting the position of the second electrode unit 40 with respect to the supporter 10 in the longitudinal direction of the supporter 10 is provided, the position of the second electrode unit 40 is provided. Can be adjusted for each user. For this reason, each electrode part 30 and 40 is easy to be attached to the appropriate position of the thigh 200.

  (12) According to the electrical stimulation device 1, the electrode portions 30 and 40 are attached to appropriate positions of the thigh 200 by performing the seventh procedure to the seventh procedure. For this reason, compared with the case where a user determines the position of each electrode part 30 and 40 based on own sense, each electrode part 30 and 40 is easily attached to the appropriate position of the thigh 200. FIG.

  (13) When a harness that supplies power to the first electrode unit 30 and a harness that supplies power to the second electrode unit 40 are provided, two long harnesses are required. On the other hand, according to the electrical stimulation device 1, the power of the power source is supplied to the first electrode unit 30 through the first harness 61, and the second power is supplied from the first electrode unit 30 through the second harness 65. Electric power is supplied to the electrode unit 40. The first harness 61 has substantially the same length as the two long harnesses, whereas the second harness 65 is shorter than the first harness 61. For this reason, the structure of the electrical stimulation apparatus 1 is simplified compared with the case where two long harnesses are provided.

  Further, in a state where the supporter 10 is mounted on the thigh 200, the second harness 65 is not exposed to the outside of the supporter 10. For this reason, a possibility that the 1st harness 61 and the 2nd harness 65 may be entangled is reduced. Moreover, it can contribute to the improvement of the design property of the electrical stimulation apparatus 1.

  (14) When the supporter 10 is mounted on the thigh 200, for example, a part of the first harness 61 and the whole of the second harness 65 exist between the supporter 10 and the thigh 200. For this reason, there exists a possibility that a user may feel discomfort because each harness 61 and 65 contacts the thigh 200 directly. On the other hand, according to the electrical stimulation device 1, since the second harness 65 is accommodated in the accommodating portion 19, the second harness 65 is difficult to directly contact the thigh 200. For this reason, the possibility that the user feels uncomfortable is reduced.

  (15) As a result of examining the site to which electrical stimulation is applied in order to improve the training effect of the quadriceps muscle, if electrical stimulation can be applied across the rectus femoris, lateral vastus muscle, and medial vastus muscle, It was confirmed that the training effect of quadriceps improved. Based on the result of this examination, the electrical stimulator 1 supports the first electrode unit 30 so that the arrangement direction of the pair of conductors 31A and 32A constituting each conductor pair 31 and 32 is along the longitudinal direction of the supporter 10. 10 is attached. Thereby, since electrical stimulation is applied so as to straddle the rectus femoris, lateral vastus muscles, and medial vastus muscles, the training effect of the quadriceps muscles is enhanced.

  (16) As a result of examining the portion to which electrical stimulation is applied in order to improve the training effect of hamstring, if electrical stimulation can be applied along two hamstrings, the training effect of hamstring can be improved. confirmed. Based on the result of this examination, the electrical stimulation apparatus 1 sets the second electrode portion 40 so that the arrangement direction of the pair of conductors 41A and 42A constituting each conductor pair 41 and 42 is along the short direction of the supporter 10. It is attached to the supporter 10. Thereby, since electrical stimulation is given along two hamstrings, the training effect of a hamstring is improved.

  (17) When the supporter 10 is attached to the thigh 200 or when the knee joint is bent after the supporter 10 is attached to the thigh 200, the supporter 10 and the back of the knee come into contact with each other. There is a risk of feeling pleasure. On the other hand, according to the electrical stimulation device 1, the supporter 10 has a constricted second portion 12, which is a portion wound around the back of the thigh 200 in the longitudinal direction, so that the supporter 10 and the back of the knee are difficult to contact. Become. For this reason, the possibility that the user feels uncomfortable is reduced.

  (18) The supporter 10 includes a first corresponding mark 20 that teaches the right half or the left half. For this reason, the user who uses the electrical stimulation apparatus 1 wears the supporter 10 corresponding to the thigh 200 of the right half body after confirming the first corresponding mark 20, for example, and the supporter 10 corresponding to the thigh 200 of the left half body. Wear. For this reason, the possibility that the opposite supporters 10 are respectively attached to the right and left thighs 200 is reduced.

  (19) The first electrode unit 30 includes a second corresponding mark 38 that teaches the right half or the left half. For this reason, the user who uses the electrical stimulation apparatus 1 attaches the 1st electrode part 30 corresponding to the 1st supporter 10 after confirming the 2nd corresponding | compatible mark 38, for example, and respond | corresponds to the 2nd supporter 10 The first electrode unit 30 is attached. For this reason, a possibility that the 1st electrode part 30 opposite to the 1st supporter 10 and the 2nd supporter 10 may be attached respectively is reduced.

  (20) The electrical stimulation device 1 includes a first protective sheet 36 that protects the surface of the sheet 33 of the first electrode unit 30. For this reason, when the protective sheet 36 is attached to the surface of the conductor arrangement portions 34A and 34B when not in use, dust or the like is less likely to adhere to the conductive gel 35 or the like.

For this reason, the deterioration of the first harness 61 is difficult to promote.

  (22) When the user wears the supporter 10 on the thigh 200, the first harness 61 may feel in the way. On the other hand, according to the electrical stimulation device 1, since the first clip 71 and the second clip 72 are attached to the common line 64 of the first harness 61, each clip is attached before the supporter 10 is attached to the thigh 200. The first harness 61 can be fixed by attaching 71 and 72 to the outer jacket 220 or the like. For this reason, when the supporter 10 is mounted on the thigh 200, the first harness 61 is unlikely to get in the way.

  (23) The user who uses the electrical stimulation apparatus wears the trousers 210 after attaching the supporter 10 to the thigh 200, for example. In this case, for example, the belt 90 inserted into the loop 82 of the holding case 80 from the outside of the trousers 210 is fastened. However, some users may feel uncomfortable with exposing the belt 90 to the outside. On the other hand, according to the electrical stimulation device 1, the belt 90 can be fastened without exposing the belt 90 to the outside by mounting the holding case 80 in the second mounting state of the holding case 80.
