Summary of the Invention

Problems to be Solved by the Invention

[0004] A low-frequency therapeutic apparatus relieves colic and pain by bringing an electrode part into contact with the surface of the body such as the abdomen or back and applying a stimulating electrical signal to the muscle through the electrode part.

[0005] The surface of the body can be divided into a plurality of cutaneous sensory zones (dermatomes) associated with the spinal nerves, and the therapeutic effect can be improved by passing electricity through a predetermined cutaneous sensory zone.

[0006] However, when the electrode part is attached to the back or the like, it is difficult to visually confirm the back side, so it is difficult to grasp the height position, the circumferential position, etc. of the electrode part. For this reason, it becomes difficult to attach the electrode part at an appropriate position.

[0007] The present disclosure has been made in view of the above problems, and an object of the present disclosure is to provide a low-frequency therapeutic apparatus and a low-frequency therapeutic apparatus unit capable of guiding an electrode part to an appropriate position on the living body surface.

Means for Solving the Problem

[0008] The low-frequency therapeutic apparatus based on the present disclosure includes an electrode unit for supplying current to the body surface, and a light irradiation unit for irradiating light for confirming the attachment position of the electrode unit to the body surface. The light irradiation unit is provided so as to be able to irradiate light parallel to the electrode unit in a facing state where the electrode unit faces the body surface with a distance therebetween.

[0009] Note that "parallel" does not only mean completely parallel, but also allows for some deviation due to manufacturing errors such as tolerances, and means substantially parallel.

[0010] According to the above configuration, before attaching the electrode unit to the body surface, with the electrode unit facing the body surface, by irradiating light irradiated from the light irradiation unit in a direction parallel to the electrode unit onto a predetermined irradiated object, the position of the electrode unit can be confirmed by confirming the position of the light irradiated on the irradiated object. Therefore, the electrode unit can be attached to an appropriate position on the body surface.

[0011] In the low-frequency therapeutic apparatus based on the present disclosure, the light irradiation unit may be located on the side opposite to the side where the body surface of the user is located with respect to the electrode unit in the facing state.

[0012] According to the above configuration, when attaching the electrode unit to the body surface, it is possible to suppress the light irradiation unit from entering between the electrode unit and the body surface.

[0013] The low-frequency therapeutic apparatus based on the present disclosure may include a main body unit for supplying current to the electrode unit. The light irradiation unit may be provided on the main body unit.

[0014] According to the above configuration, the light irradiation unit can be installed at a stable position, and the position of the light irradiated from the light irradiation unit can also be stabilized.

[0015] In the low-frequency therapeutic apparatus based on the present disclosure, the main body portion may include a bottom surface portion facing the body surface in the facing state, and a first side wall portion and a second side wall portion that stand up from the outer edge of the bottom surface portion and face each other with a distance therebetween. The light irradiation unit may include a first light irradiation unit provided on the first side wall portion and a second light irradiation unit provided on the second side wall portion. In this case, the first light irradiation unit and the second light irradiation unit may be arranged such that their positions in the orthogonal direction orthogonal to the direction in which the first side wall portion and the second side wall portion face each other are the same position.

[0016] According to the above configuration, by checking the position where the light irradiated from the first light irradiation unit provided on the first side wall portion irradiates the object to be irradiated and the position where the light irradiated from the second light irradiation unit provided on the second side wall portion irradiates another object to be irradiated, while grasping the position of the electrode portion (more specifically, the rotation state), the position of the electrode portion can be adjusted. For example, when the direction in which the first side wall portion and the second side wall portion face each other is inclined from the horizontal direction, by adjusting the irradiation position so that the irradiation position from the first light irradiation unit and the irradiation position from the second light irradiation unit are at the same height position in the vertical direction, the direction in which the first side wall portion and the second side wall portion face each other can be made horizontal. The electrode portion can be arranged at an appropriate position.

[0017] In the low-frequency therapeutic apparatus based on the present disclosure, the main body portion may include a bottom surface portion facing the body surface in the facing state and a peripheral wall portion provided along the outer edge of the bottom surface portion. The light irradiation unit may include a first light irradiation unit provided at a first position on the peripheral wall portion and a second light irradiation unit provided at a second position rotated 90 degrees in the circumferential direction of the peripheral wall portion from the first position.

[0018] According to the above configuration, by checking the irradiation positions of two lights irradiated in directions 90 degrees different from each other, while grasping the position of the electrode portion (more specifically, the rotation state), the position of the electrode portion can be adjusted.

[0019] The low-frequency therapeutic apparatus based on the present disclosure may include a gripping portion provided on the main body portion. The gripping portion may be arranged such that the light irradiated from the light irradiation portion does not hit the hand of the user who grips the gripping portion when the user grips the gripping portion.

[0020] According to the above configuration, the attachment position of the electrode portion can be adjusted while gripping the gripping portion.

[0021] In the low-frequency therapeutic apparatus based on the present disclosure, when viewed from the normal direction of the electrode portion, the light irradiation portion may be arranged such that the light irradiated from the light irradiation portion overlaps at least a part of the electrode portion.

[0022] According to the above configuration, since light is irradiated from the light irradiation portion so as to overlap at least a part of the electrode portion when viewed from the normal direction of the electrode portion, the position of the electrode portion can be confirmed by confirming the position where the light is irradiated.

[0023] The low-frequency therapeutic apparatus based on the present disclosure may include a control portion that operates the operation of the light irradiation portion. The control portion may control the light irradiation portion from an on state to an off state when a current is supplied to the electrode portion.

[0024] According to the above configuration, since light is no longer irradiated from the light irradiation portion in accordance with the start of treatment of the low-frequency therapeutic apparatus, power consumption can be suppressed.

[0025] The low-frequency therapeutic apparatus based on the present disclosure includes the low-frequency therapeutic apparatus and an auxiliary member on which an index of the attachment position is indicated. By irradiating light from the light irradiation portion toward the auxiliary member, the attachment position can be confirmed.

[0026] According to the above configuration, the index of the attachment position can be confirmed by the position of the light, and the electrode portion can be arranged at a more appropriate position.

Advantages of the Invention

[0027] According to the present disclosure, it is possible to provide a low-frequency therapeutic apparatus and a low-frequency therapeutic apparatus unit capable of guiding an electrode unit to an appropriate position on the living body surface.

Modes for Carrying Out the Invention

[0029] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments shown below, the same or common parts are denoted by the same reference numerals in the drawings, and the description thereof will not be repeated.

[0030] (Embodiment 1) FIG. 1 is a perspective view showing a low-frequency therapeutic apparatus according to Embodiment 1. FIG. 2 is a schematic front view of the low-frequency therapeutic apparatus according to Embodiment 1. With reference to FIGS. 1 and 2, the low-frequency therapeutic apparatus 1 according to Embodiment 1 will be described.

[0031] The low-frequency therapeutic apparatus 1 includes a main body portion 10, electrode portions 20 and 30, a holding portion 40, and a light irradiation portion 50. The low-frequency therapeutic apparatus 1 supplies a low-frequency pulsed current to the electrode portions 20 and 30 that are in contact with the body surface of the user, for example, to supply a current to the body surface and relieve the pain of the user. The frequency of the low-frequency pulsed current is, for example, 1 Hz or more and 1200 Hz or less.

[0032] The main body portion 10 includes a housing case 11 and an operation portion 19. Inside the housing case 11, a control portion 18 is accommodated. The control portion 18 is electrically connected to the above-described electrode portions 20 and 30 via an electrical path (not shown), and controls the current, voltage, etc. flowing through the electrode portions 20 and 30. The control portion 18 also controls the operation of the light irradiation portion 50. The control portion 18 is constituted by a circuit board or the like.

[0033] The operation portion 19 is provided on the housing case 11. The operation portion 19 has, for example, a switch for measurement. The operation portion 19 is not limited to a push-type switch, and may be, for example, a pressure-sensitive (resistive) or proximity (capacitive) touch panel type switch. Further, a display portion may be provided on the housing case 11 separately from the operation portion 19.

[0034] The housing case 11 has a box shape. The housing case 11 has a top surface portion 12, a bottom surface portion 13, a first side wall portion 14, a second side wall portion 15, a first wall portion 16, and a second wall portion 17. The top surface portion 12 and the bottom surface portion 13 face each other in a predetermined first direction. At least a part of the bottom surface portion 13 contacts the body surface 80 (see FIG. 3) when the low-frequency therapeutic device 1 is used. The first side wall portion 14, the second side wall portion 15, the first wall portion 16, and the second wall portion 17 constitute the peripheral wall portion of the housing case 11. The first side wall portion 14 and the second side wall portion 15 are provided so as to stand up from the outer edge of the bottom surface portion 13 and face each other with a distance therebetween. The first side wall portion 14 and the second side wall portion 15 face each other in a second direction orthogonal to the first direction. The first wall portion 16 and the second wall portion 17 are provided so as to stand up from the outer edge of the bottom surface portion 13 and face each other with a distance therebetween. The first wall portion 16 and the second wall portion 17 face each other in a third direction orthogonal to the first direction and the second direction.

[0035] When viewed in plan, the electrode portions 20 and 30 are arranged at intervals in the first direction such that the main body portion 10 is positioned between the electrode portion 20 and the electrode portion 30. The electrode portion 20 is arranged on one side in the first direction with respect to the main body portion 10. The electrode portion 30 is arranged on the other side in the first direction with respect to the main body portion 10.

[0036] The electrode portions 20 and 30 are parts for passing an electric current through the user. The electrode portions 20 and 30 are provided so as to be attachable to the body surface of the user using adhesion. The electrode portions 20 and 30 have an adhesive portion. The electrode portions 20 and 30 may be, for example, gel pads, or may be those in which an adhesive layer and a conductive member are laminated. By supplying an electric current to the electrode portions 20 and 30 in a state where the electrode portions 20 and 30 are in contact with the body surface of the user, an electric current can be passed through the user.

[0037] The holding portion 40 holds the electrode portions 20 and 30. The holding portion 40 has, for example, flexibility and is provided so as to be deformable along the body surface. As the holding portion 40, for example, a fabric having insulation can be adopted.

[0038] The holding part 40 is fixed to the main body part 10, for example. The holding part 40 has a first holding part 41 and a second holding part 42. The first holding part 41 holds the electrode part 20. The shape of the first holding part 41 is substantially the same as the shape of the electrode part 20. The second holding part 42 holds the electrode part 30. The shape of the second holding part 42 is substantially the same as the shape of the electrode part 30. The first holding part 41 and the second holding part 42 may be connected by a connecting part.

[0039] The light irradiation part 50 is provided so as to be able to irradiate light. The light irradiation part 50 includes a light source and is configured to irradiate linear light. For example, laser light is irradiated from the light irradiation part 50. A slit having an opening is arranged in front of the light source, and the laser light may be emitted in a shape corresponding to the opening shape of the slit. The above-mentioned opening shape may be rectangular, polygonal, or cross-shaped. Further, as the opening shape, an oval shape such as a circular shape, an elliptical shape, or a track shape may be used.

[0040] The light irradiation part 50 is provided on the main body part 10. Thereby, the light irradiation part 50 can be installed at a stable position, and the light irradiated from the light irradiation part 50 can also be stabilized. The light irradiation part 50 includes a first light irradiation part 51 and a second light irradiation part 52.

[0041] The first light irradiation part 51 is provided on the first side wall part 14. The second light irradiation part 52 is provided on the second side wall part 15. The irradiation directions of the first light irradiation part 51 and the second light irradiation part 52 are different from each other. In the present embodiment, the second light irradiation part 52 irradiates light in a direction opposite to the irradiation direction of the first light irradiation part 51.

[0042] FIG. 3 is a view seen from above of the state where the low-frequency therapeutic apparatus according to Embodiment 1 is attached to the back side.

[0043] As shown in Fig. 3, when the low-frequency therapeutic apparatus 1 is attached to the back side, first, the main body 10 is brought into contact with the body surface 80 on the back side. Specifically, the bottom surface portion 13 of the main body 10 is brought into contact with the body surface 80. In this state, the electrode portions 20 and 30 are separated from the body surface 80. That is, the electrode portions 20 and 30 face the body surface 80 with a distance therebetween. In such an opposed state where the electrode portions 20 and 30 face the body surface 80, the light irradiation portion 50 is located on the side opposite to the side where the body surface 80 is located with respect to the electrode portions 20 and 30. Thereby, when the electrode portions 20 and 30 are attached to the body surface 80, it is possible to prevent the light irradiation portion 50 from entering between the electrode portions 20 and 30 and the body surface 80. That is, the light can be surely irradiated from the light irradiation portion 50 toward the outside.

[0044] In the opposed state, the first light irradiation portion 51 and the second light irradiation portion 52 are arranged such that their positions in the orthogonal direction (the third direction) orthogonal to the direction (the second direction) in which the first side wall portion 14 and the second side wall portion 15 face each other are the same position. Note that the same position means that manufacturing errors such as tolerances are allowed and they are substantially the same.

[0045] Fig. 4 is a view of the state of attaching the low-frequency therapeutic apparatus according to Embodiment 1 to the back side as seen from the back side. In Fig. 4, for easy illustration of the dermatome, for convenience, a state where the user is not holding the low-frequency therapeutic apparatus 1 is illustrated. When actually attaching the low-frequency therapeutic apparatus 1 to the back side, the user positions it while holding the low-frequency therapeutic apparatus 1 by hand. Since it is possible to effectively perform treatment by arranging the low-frequency therapeutic apparatus (more specifically, the electrode portions 20 and 30) on a dermatome appropriate for treatment among a plurality of skin sensory zones (dermatomes), alignment of the low-frequency therapeutic apparatus 1 is important.

[0046] As shown in Fig. 4, when aligning the low-frequency therapeutic apparatus 1, light is irradiated from the light irradiation portion 50, and the position of the light irradiated on the irradiated object is confirmed. Here, as the irradiated object, the indoor wall portions W1 and W2 are illustrated and described as an example, but the irradiated object is not limited to the indoor wall portions.

[0047]

[0047] The light irradiation unit 50 is provided so as to be able to irradiate light parallel to the electrode units 20 and 30 in the above-described facing state in which the electrode units 20 and 30 face each other with a distance from the body surface 80. When viewed from the normal direction of the electrode units 20 and 30, the light irradiation unit 50 is arranged such that the light irradiated from the light irradiation unit 50 overlaps at least a part of the electrode units 20 and 30. Thereby, by checking the position where the light is irradiated, the position (more specifically, the height position) of the electrode units 20 and 30 can be easily checked.

[0048] From the first light irradiation unit 51, light L1 is irradiated toward one side in the second direction (the side opposite to the side where the second side wall portion 15 is located), and the light hits the wall portion W1. From the second light irradiation unit 52, light L2 is irradiated toward the other side in the second direction (the side opposite to the side where the first side wall portion 14 is located), and the light hits the wall portion W2.

[0049] The user can grasp the position of the electrode units 20 and 30 (specifically, the height position in the vertical direction and the rotational state) by checking the irradiation position P11 where the light L1 irradiated from the first light irradiation unit 51 hits the wall portion W1 and the irradiation position P12 where the light L2 irradiated from the second light irradiation unit 52 hits the wall portion W2.

[0050]

[0048] For example, when the second direction is inclined from the horizontal direction, by adjusting the irradiation positions P11 and P12 such that the irradiation position P11 and the irradiation position P12 are at the same height position in the vertical direction, the second direction can be made horizontal. Also, by adjusting the positions of P11 and P12 in the vertical direction (the height position from the floor surface F1), the height position of the electrode units 20 and 30 on the back side can be adjusted. In this way, by grasping the position of the electrode units 20 and 30 and bringing the electrode units 20 and 30 into contact with the body surface 80, the electrode units 20 and 30 can be attached at an appropriate position.

[0051] FIG. 5 is a diagram showing the ON / OFF states of current supply to the light irradiation unit and the electrode unit of the low-frequency therapeutic apparatus according to Embodiment 1.

[0052] As shown in FIG. 5, when current is supplied to the electrode units 20 and 30, the control unit 18 controls the light irradiation unit 50 from the on state to the off state. Thereby, since light is no longer irradiated from the light irradiation unit in accordance with the start of treatment of the low-frequency therapeutic apparatus, power consumption can be suppressed. Further, during alignment, light is irradiated from the light irradiation unit 50, so that alignment can be easily performed.

[0053] (Embodiment 2) FIG. 6 is a schematic plan view of the low-frequency therapeutic apparatus according to Embodiment 2. With reference to FIG. 6, the low-frequency therapeutic apparatus 1A according to Embodiment 2 will be described.

[0054] As shown in FIG. 6, the low-frequency therapeutic apparatus 1A according to Embodiment 2 has a different position of the second light irradiation unit 52 compared to the low-frequency therapeutic apparatus 1 according to Embodiment 1. Other configurations are substantially the same.

[0055] The first light irradiation unit 51 is provided at the first position P1 on the peripheral wall of the main body unit 10, and the second light irradiation unit 52 is provided at the second position P2 rotated 90 degrees in the circumferential direction of the peripheral wall from the first position P1. Specifically, for example, the first light irradiation unit 51 is provided on the first side wall 14, and the second light irradiation unit 52 is provided on the first wall 16.

[0056] Even in such a configuration, the low-frequency therapeutic apparatus 1A according to Embodiment 2 can obtain substantially the same effects as the low-frequency therapeutic apparatus 1 according to Embodiment 1. By checking the irradiation positions of the two lights irradiated in directions different by 90 degrees, the positions of the electrode units 20 and 30 (more specifically, the rotation state) can be grasped, and the positions of the electrode units 20 and 30 can be adjusted.

[0057] (Embodiment 3) FIG. 7 is a schematic plan view of the low-frequency therapeutic apparatus according to Embodiment 3. With reference to FIG. 7, the low-frequency therapeutic apparatus 1B according to Embodiment 3 will be described.

[0058] As shown in Fig. 7, compared with the low-frequency therapeutic apparatus 1 of Embodiment 1, the low-frequency therapeutic apparatus 1B according to Embodiment 3 is different in that a gripping portion 60 is provided and the light irradiation portion 50 includes a third light irradiation portion 53. Other configurations are substantially the same.

[0059] The first light irradiation portion 51 and the second light irradiation portion 52 are provided at a 180-degree pitch in the circumferential direction of the peripheral wall portion, and the third light irradiation portion 53 is provided at the center between the first light irradiation portion 51 and the second light irradiation portion 52 in the circumferential direction. The third light irradiation portion 53 is arranged at a position rotated 90 degrees in the circumferential direction from each of the first light irradiation portion 51 and the second light irradiation portion 52.

[0060] Specifically, the first light irradiation portion 51 is provided on the first side wall portion 14, the second light irradiation portion 52 is provided on the second side wall portion 15, and the third light irradiation portion 53 is provided on the first wall portion 16. The third light irradiation portion 53 is provided so as to be able to irradiate the light L3 on one side in the third direction (the side opposite to the side where the second wall portion 17 is located).

[0061] In the above description, the case where three light irradiation portions are provided is exemplified, but the number of light irradiation portions may be two.

[0062] The gripping portion 60 is provided on the main body portion 10. The gripping portion 60 is, for example, a handle and has a U shape. The gripping portion 60 is arranged so that the light irradiated from the light irradiation portion 50 does not hit the hand of the user who grips the gripping portion 60 in a state where the user grips the gripping portion 60. The gripping portion 60 is provided on the second wall portion 17.

[0063] Even when configured in this way, the low-frequency therapeutic apparatus 1B according to Embodiment 3 can obtain substantially the same effects as the low-frequency therapeutic apparatus 1 according to Embodiment 1. Since the attachment positions of the electrode units 20 and 30 can be adjusted while holding the grip unit 60, the convenience can be improved. Further, by aligning the electrode units 20 and 30 using the lights L1, L2, and L3 from the first light irradiation unit 51, the second light irradiation unit 52, and the third light irradiation unit 53, more appropriate alignment can be achieved.

[0064] (Embodiment 4) FIG. 8 is a schematic plan view of the low-frequency therapeutic apparatus according to Embodiment 4. With reference to FIG. 8, the low-frequency therapeutic apparatus 1C according to Embodiment 4 will be described.

[0065] As shown in FIG. 8, the position of the grip unit 60 of the low-frequency therapeutic apparatus 1C according to Embodiment 4 is different from that of the low-frequency therapeutic apparatus 1B according to Embodiment 3. The other configurations are substantially the same. The grip unit 60 is provided on the top surface portion 12 of the main body unit 10.

[0066] Even when configured in this way, the low-frequency therapeutic apparatus 1C according to Embodiment 4 can obtain substantially the same effects as the low-frequency therapeutic apparatus 1B according to Embodiment 3.

[0067] (Embodiment 5) FIG. 9 is a schematic plan view of the low-frequency therapeutic apparatus according to Embodiment 5. With reference to FIG. 9, the low-frequency therapeutic apparatus 1D according to Embodiment 5 will be described.

[0068] As shown in FIG. 9, the low-frequency therapeutic apparatus 1D according to Embodiment 5 is different from the low-frequency therapeutic apparatus 1B according to Embodiment 3 in that the third light irradiation unit 53 is not provided and the configuration of the grip unit 60D is different.

[0069] The gripping part 60D is constituted by the recesses 61 and 62. The recess 61 is provided on the second wall part 17. The recess 61 is provided so as to be recessed toward the side where the first wall part 16 is located. The recess 62 is provided on the first wall part 16. The recess 62 is provided so as to be recessed toward the side where the second wall part 17 is located. For example, when the user grips the main body part 10, the recess 61 is pressed by the thumb side, and the recess 62 is supported by the index finger, middle finger, ring finger, and little finger.

[0070] Even in such a configured case, the low-frequency therapeutic apparatus 1D according to the fifth embodiment can obtain substantially the same effects as the low-frequency therapeutic apparatus 1B according to the third embodiment.

[0071] (Embodiment 6) FIG. 10 is a schematic diagram showing a low-frequency therapeutic apparatus unit according to the sixth embodiment. With reference to FIG. 10, the low-frequency therapeutic apparatus unit 100 according to the sixth embodiment will be described.

[0072] As shown in FIG. 10, the low-frequency therapeutic apparatus unit 100 according to the sixth embodiment includes a low-frequency therapeutic apparatus 1 and an auxiliary member 90. The low-frequency therapeutic apparatus 1 is the same as that in the first embodiment, but any of the low-frequency therapeutic apparatuses in the above-described first to fifth embodiments can be adopted.

[0073] An index of the attachment position is shown on the auxiliary member 90. The auxiliary member 90 is, for example, a poster with the height position from the floor surface F1 marked. The auxiliary member 90 may be singular or plural. By attaching the auxiliary member 90 to the above-described wall parts W1 and W2 and checking the position of the light (L1 in FIG. 10) irradiated on the auxiliary member 90, the position of the low-frequency therapeutic apparatus 1 can be easily checked.

[0074] In the above description, the case where the auxiliary member 90 is provided separately from the low-frequency therapeutic apparatus 1 has been exemplified and described. However, the auxiliary member 90 may be incorporated into the low-frequency therapeutic apparatus 1. Specifically, a translucent portion with a scale described in front of the light source of the light irradiation unit 50 may be provided, and it may be provided such that an index such as a scale is projected onto an irradiated object (for example, the wall portion W1) by the light irradiated from the light source. In this case, by checking the position of the light irradiated on the projected image, the position of the low-frequency therapeutic apparatus 1 can be easily confirmed. Further, since it is not necessary to provide the auxiliary member 90 as a separate member, the cost can be reduced.

[0075] As described above, the embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims, and includes all modifications within the meaning and scope equivalent to the claims.
