[0001] The present invention relates to an electric potential therapeutic device. [Background technology]

[0002] Conventionally, electric potential therapy devices that generate an electric field to apply an electric potential to the human body for treatment are known. For example, the following Patent Document 1 describes a mat-shaped electric potential therapy device on which the human body lies supine. The electric potential therapy device includes a cushioning body that can be used as bedding. Potential means that generate an electric field are arranged in a serpentine pattern over almost the entire surface of the cushioning body. The human body lying supine on the cushioning body is securely placed in the electric field and is given an electric potential. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2005-21465 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned configuration requires a large number of wirings for generating potentials, which poses a problem of high manufacturing costs.

[0005] The present invention was completed in view of the above circumstances, and has an object to provide an electric potential therapy device capable of reducing manufacturing costs. [Means for solving the problem]

[0006] The electric potential therapy device of the present invention comprises a sheet-shaped main body having an electric potential generating area for generating an electric potential, the electric potential generating area being provided on one side from the center of the main body. Effect of the Invention

[0007] According to the present invention, a potential can be reliably applied to the human body by lying down on the main body with the head, which has a relatively small surface area, placed on the side where the potential generating area is not provided, and the waist, which has a relatively large surface area, placed on the side where the potential generating area is provided. By providing the potential generating area biased to one side of the main body, the amount of wiring for potential generation can be reduced compared to when the potential generating area is provided over the entire surface of the main body, and therefore manufacturing costs can be reduced.

[0009] A preferred embodiment of the present invention is described below.

[0010] The electric potential therapy device of the present invention has a notification unit that detects whether an electric potential is applied to the human body by a part of the human body approaching the device, and notifies the user that an electric potential is applied to the human body when an electric potential is applied to the human body, and the notification unit may be provided integrally with the main body and disposed on the other side of the center of the main body. With this configuration, the notification unit is disposed close to the head when the head, which has a relatively small surface area, is placed on the side where the electric potential generation area is not wide. Therefore, the user can easily check whether an electric potential is applied to the body by bringing a fingertip or the like close to the notification unit while lying on the main body.

[0011] The electric potential therapy device of the present invention may also have an electric potential manipulation unit that manipulates the generation and stopping of the electric potential in the electric potential generating region, and the electric potential manipulation unit may be provided integrally with the main body and disposed on the other side of the main body. With this configuration, when the user lies on the main body with the head, which has a relatively small surface area, placed on the side where the electric potential generating region is not extended, the electric potential manipulation unit is disposed in a position close to the head. Therefore, the user can easily manipulate the generation and stopping of the electric potential while lying on the main body.

[0012] In the electric potential therapy device of the present invention, the main body may have a heater for warming the main body. With this configuration, the user can warm the main body to improve the comfort of use.

[0013] The electric potential therapy device of the present invention may also have a heater control unit that controls the heater, and the heater control unit may heat the heater at a first temperature for a predetermined time from when the heater starts to heat, and heat the heater at a second temperature lower than the first temperature after the predetermined time has elapsed. With this configuration, the temperature of the main body is slightly lowered after the predetermined time has elapsed from when the heater starts to heat. Therefore, the user can relax his or her body.

[0014] In the electric potential therapy device of the present invention, the heater control unit may start heating the heater before the electric potential is stopped. With this configuration, the main body is warmed up before the electric potential is stopped, so that the user can smoothly resume activities after the electric potential therapy is finished.

[0015] In the electric potential therapy device of the present invention, the heater control unit may gradually increase the temperature of the heater before the electric potential is stopped. This configuration provides a better feeling of use than a case in which the temperature of the main body unit increases suddenly before the electric potential is stopped.

[0016] <Example> An embodiment of the present invention will be described in detail below with reference to Figs. 1 to 6. The electric potential therapy device 10 in this embodiment is used for the purpose of relieving insomnia, headaches, stiff shoulders, constipation, etc. The electric potential therapy device 10 is used by being laid on the surface of, for example, a single-size mat M, as shown in Fig. 1.

[0017] The electric potential therapy device 10 includes a main body 20 and a control unit 30. The main body 20 is in the form of a substantially rectangular sheet that is slightly smaller than the mat M. For example, the longitudinal dimension of the main body 20 is 1120 mm, and the lateral dimension is 740 mm.

[0018] 1, the X-axis direction is along the short side of the main body 20, and the Y-axis direction is along the long side of the main body 20. In the following, the direction along the X-axis of each component will be described as the horizontal direction, and the direction along the Y-axis as the vertical direction. In addition, when viewed from the front side of the electric potential therapy device 10 laid on the surface of the mat M, the right side (positive side of the X-axis) will be described as the right side, the left side (negative side of the X-axis) as the left side, the upper side (positive side in the Y-axis direction) as the upper side, and the lower side (negative side in the Y-axis direction) as the lower side.

[0019] The main body 20 is provided with a potential generating area 21 that generates a potential. As shown in FIG. 1, the potential generating area 21 is a horizontally elongated rectangle whose horizontal dimension is larger than its vertical dimension. The vertical dimension of the potential generating area 21 is larger than half the length of the torso of an average adult (from the shoulders to the base of the thighs). The horizontal dimension of the potential generating area 21 is larger than the width of an average adult (the width in the left-right direction including both arms when both arms are lowered on either side of the waist). The dimensions of the potential generating area 21 are, for example, 420 mm in the vertical direction and 540 mm in the horizontal direction. The potential generating area 21 will be described in detail later.

[0020] As shown in FIG. 2, the electric potential therapy device 10 is provided with a cover 11. The cover 11 is rectangular in plan view. The cover 11 covers the entire main body 20. The cover 11 is freely attachable to and detachable from the main body 20. A corner of the cover 11 is provided with a cutout 12 for exposing the control unit 30. The cutout 12 is formed by cutting the corner of the cover 11. The cutout 12 has an arc shape that fits the outer shape of the control unit 30.

[0021] As shown in FIG. 3, the electric potential therapy device 10 is equipped with a heater 22 that heats the main body section 20. Heating by the heater 22 can be performed in conjunction with the generation of an electric potential or independently of the generation of an electric potential. The heater 22 is linear and extends from the control section 30 into the inside of the main body section 20. The heater 22 is disposed in a serpentine manner in the main body section 20. The area in which the heater 22 heats the main body section 20 extends on the same side of the main body section 20 as the electric potential generation area 21. The electric potential generation area 21 and the heating area of ​​the heater 22 overlap. The heating area of ​​the heater 22 is larger than the electric potential generation area 21.

[0022] 3, potential wires 23 that generate a potential are densely arranged in the potential generating region 21 of the main body 20. The potential wires 23 extend from the control unit 30 into the inside of the main body 20. The potential wires 23 are arranged in a serpentine manner in the main body 20. A negative voltage (e.g., 600 V) is applied to the potential wires 23.

[0023] As shown in FIG. 3, the electric potential generating region 21 is provided so as to extend downward (to one side) from the center in the vertical direction of the main body 20. The center of the main body 20 is a portion near the center C2, including the center C2 in the vertical and horizontal directions of the main body 20. The center of the main body 20 is a portion that comes into contact with the torso of a person lying on the main body 20. The center C2 of the main body 20 is located within the electric potential generating region 21. The center C1 of the electric potential generating region 21 in the vertical and horizontal directions is located below the center C2 of the main body 20. The upper end U1 of the electric potential generating region 21 is located above the center C2 of the main body 20. The lower end U2 of the electric potential generating region 21 is located in the lower end region R1, which is the lowermost region obtained by dividing the main body 20 into four vertical regions. The electric potential generating region 21 extends evenly on both the left and right sides from the center line L1 in the horizontal direction of the main body 20. The left and right ends S of the electric potential generating region 21 are located in the left and right regions R2, respectively, which are the left and right ends of the region obtained by dividing the main body 20 into four regions in the horizontal direction.

[0024] The center of the main body 20 is a torso support section that supports the torso of the user. The upper side (the other side) of the main body 20 is a head support section that supports the head of the user. The electric potential generating region 21 is disposed in the torso support section of the main body 20, avoiding the head support section.

[0025] When the lower (one side) edge of the outer edge of the main body 20 is referred to as the first edge 20F and the upper (other side) edge is referred to as the second edge 20S, the portion of the potential generating region 21 between the first edge 20F of the main body 20 and the center C2 of the main body 20 is wider than the portion between the second edge 20S of the main body 20 and the center C2 of the main body 20. In other words, when the main body 20 is equally divided in the vertical direction, the area of ​​the potential generating region 21 is larger in the portion provided on the lower side than in the portion provided on the upper side of the main body 20. The second edge 20S is the edge on the side of the outer edge of the main body 20 where the control unit 30 is provided.

[0026] An area where no potential is generated (referred to as outer area 24) extends outside potential generation area 21 in main body 20. The vertical dimension of outer area 24 above potential generation area 21 is, for example, 465 mm.

[0027] The control unit 30 is provided integrally with the main body 20, as shown in FIG. 3. The control unit 30 is disposed in the left corner of the upper end of the main body 20. The control unit 30 is circular in plan view. The surface of the control unit 30 is an operation surface 32. Approximately three-quarters of the control unit 30 protrudes outward from the outer edge of the main body 20. More specifically, approximately the upper half of the control unit 30 protrudes upward from the upper edge (second edge 20S) of the main body 20, and approximately the left half of the control unit 30 protrudes leftward from the left edge of the main body 20. A power cord 31 extends from the control unit 30.

[0028] 4, the control unit 30 includes a power supply unit 33, a body movement detection unit 34, a notification unit 35, an operation unit 36, a control unit 37, and a display unit 38. The power supply unit 33, the body movement detection unit 34, the notification unit 35, the operation unit 36, the control unit 37, and the display unit 38 are electrically connected to each other. The power supply unit 33 supplies power supplied from a power source to the body movement detection unit 34, the notification unit 35, the operation unit 36, the control unit 37, and the display unit 38.

[0029] The body movement detection unit 34 acquires information regarding whether or not a person is standing on the surface of the main body unit 20, and regarding the body movement of the person standing on the surface of the main body unit 20. The body movement detection unit 34 has, for example, an acceleration sensor and an angular velocity sensor.

[0030] The notification unit 35 includes a detection unit 39 and a notification display unit 41, as shown in FIG. 4. The detection unit 39 and the notification display unit 41 are provided on the operation surface 32, as shown in FIG. 5. The detection unit 39 detects whether or not a potential is applied to the human body by a part of the human body contacting or approaching the detection unit 39. The detection unit 39 detects a change in the electric field (voltage) in the electric potential generating region 21 through the contacting or approaching human body, and detects whether the detected change in the electric field is a change caused by the application of a potential to the human body. The notification display unit 41 is an LED lamp. When the detection unit 39 detects that a potential is applied to the human body, the notification unit 35 notifies the fact on the notification display unit 41. Specifically, when the notification unit 35 does not detect a potential of the human body, the notification unit 35 keeps the notification display unit 41 in an off state, and when the notification unit 35 detects a potential of the human body, the notification unit 35 turns on the notification display unit 41.

[0031] 4 and 5, the operation unit 36 ​​includes a power supply operation unit 42 for operating the power supply, a potential operation unit 43 for operating the potential, and a heater operation unit 44 for operating the heater 22. The heater operation unit 44 includes a first heater operation unit 45 and a second heater operation unit 46. These operation units 36 are provided on the operation surface 32. The operation units 36 are operated by pressing them.

[0032] The power supply operation unit 42 switches the power supply on and off by operation. The potential manipulation unit 43 switches between generating and stopping the potential by operation. The potential manipulation unit 43 can also select the length of time for generating the potential (potential operation time) by operation. The potential operation time can be selected from 6 hours, 7 hours, and 8 hours.

[0033] The first heater operation unit 45 switches between heating and stopping of the heater 22 by operation. The first heater operation unit 45 can also select the heating temperature of the heater 22 by operation. The heating temperature selected by operation of the first heater operation unit 45 is referred to as a first temperature H1. The first temperature H1 can be selected from low, medium, and high. By pressing the first heater operation unit 45, it can be switched in the order of low, medium, high, and stopped.

[0034] The second heater operation unit 46 can be operated to start and stop a fluctuation mode that automatically varies the heating temperature of the heater 22. When the fluctuation mode is not started, the heater 22 is heated at a constant temperature.

[0035] 4, the control unit 37 has a potential control unit 47 that controls the potential, and a heater control unit 48 that controls the heater 22. When the potential manipulation unit 43 is operated to generate a potential, the potential control unit 47 applies a negative voltage to the potential wire 23 to generate a potential in the potential generation region 21. The potential control unit 47 continues to pass electricity to the potential wire 23 according to the potential operation time selected by the operation of the potential manipulation unit 43. When the potential manipulation unit 43 is operated to stop the potential, the potential control unit 47 stops the passage of electricity to the potential wire 23.

[0036] When the first heater operation unit 45 is operated to start heating, the heater control unit 48 heats the heater 22. The heater control unit 48 increases the temperature of the heater 22 to the heating temperature selected by operation of the first heater operation unit 45. When the first heater operation unit 45 is operated to stop heating, the heater control unit 48 stops heating of the heater 22.

[0037] When the second heater operation unit 46 is operated to start the fluctuation mode, the heater control unit 48 fluctuates the temperature of the heater 22 in accordance with a predetermined program. In the fluctuation mode, as shown in Fig. 6, the heater control unit 48 provides a pause time TS for temporarily suspending heating of the heater 22 between a heating start time P1 of the heater 22 and a heating stop time P2 of the heater 22.

[0038] The operation of the heater 22 from the heating start point P1 of the heater 22 to the start point P3 of the temporary stop time TS of the heater 22 is referred to as early operation. The operation from the end point P4 of the temporary stop time TS of the heater 22 to the heating stop point P2 of the heater 22 is referred to as late operation. The heater control unit 48 continuously performs the early operation for a predetermined time T1. The heater control unit 48 continuously performs the late operation for a predetermined time T2.

[0039] The predetermined time T1 for the early operation is, for example, 90 minutes. If the body movement detection unit 34 detects little human body movement even within the predetermined time T1 for the early operation, the heater control unit 48 stops the operation of the heater 22. In other words, the predetermined time T1 for the early operation may be shorter than the specified time depending on the human body movement.

[0040] The timing to start the later operation is determined based on the end point P5 of the potential operation time. The end point P4 of the temporary stop time TS of the heater 22, i.e., the start point of the later operation, is a predetermined time T3 before the end point P5 of the potential operation time. The predetermined time T3 is, for example, 45 minutes. The heating stop point P2 of the heater 22, i.e., the end point of the later operation, is a predetermined time T4 after the end point P5 of the potential operation time. The predetermined time T4 is, for example, 60 minutes. The predetermined time T2 of the later operation is the sum of the predetermined time T3 and the predetermined time T4.

[0041] In the first operation, the heater control unit 48 maintains the heater 22 at a first temperature H1 for a predetermined time T5 from a heating start point P1 of the heater 22. The predetermined time T5 is, for example, 30 minutes. After the predetermined time T5 has elapsed, the heater control unit 48 lowers the heater 22 to a second temperature H2 that is slightly lower than the first temperature H1. The heater control unit 48 maintains the heater 22 at the second temperature H2 until a start point P3 of a pause time TS of the heater 22. The difference between the first temperature H1 and the second temperature H2 is, for example, 2 degrees.

[0042] In the later operation, the heater control unit 48 increases the temperature of the heater 22 in stages (e.g., in three stages) from the end point P4 of the temporary stop time TS of the heater 22 to the end point P5 of the potential application time. The heater control unit 48 sets the heater 22 to a second temperature H2 at the end point P4 of the temporary stop time TS of the heater 22. The heater control unit 48 sets the heater 22 to a third temperature H3 that is slightly higher than the first temperature H1 at the end point P5 of the potential application time. The difference between the third temperature H3 and the first temperature H1 is, for example, 2 degrees.

[0043] As shown in Figures 4 and 5, the display unit 38 includes a power supply display unit 49 that displays the state of the power supply, a potential display unit 51 that displays the state of the potential, and a heater display unit 52 that displays the state of the heater 22.

[0044] The display unit 38 is an LED lamp arranged on the operation surface 32. The power display unit 49 lights up when the power is on and goes out when the power is off.

[0045] The potential display unit 51 has three lamps corresponding to the selected potential operating time. The lamp of the selected potential operating time is turned on when a potential is generated in the potential generating area 21. When no potential is generated in the potential generating area 21, all the lamps are turned off.

[0046] The heater display unit 52 includes a first heater display unit 53 and a second heater display unit 54. The first heater display unit 53 includes three lamps corresponding to the selected heating temperature. When the heater 22 is in a heated state, the lamp of the selected heating temperature is turned on. When the heater 22 is in a non-heated state, all the lamps are turned off. The second heater display unit 54 is turned on when the variable mode is selected, and is turned off when the variable mode is not selected.

[0047] Next, an example of how to use the electric potential therapy device 10 according to this embodiment will be described. First, as shown in Fig. 1, the user places the main body 20 of the electric potential therapy device 10 on the surface of a mat M. At this time, the user places the electric potential therapy device 10 toward the upper side of the mat M. The entire electric potential therapy device 10, including the control unit 30, is placed on the surface of the mat M. The user inserts the power cord 31 into an outlet.

[0048] Next, the user lies on his / her back on the surface of the main body unit 20. The user may also lie on his / her side. The control unit 30 is placed near the user's head. The user's lower back is placed on the front side of the electric potential generating region 21. The user's head is placed in the outer region 24.

[0049] Next, the user operates the power supply operation unit 42 of the control unit 30 to turn on the power supply, whereby the power supply display unit 49 lights up.

[0050] Next, the user operates potential operation unit 43 of control unit 30 to generate a potential in potential generating area 21. At this time, the user operates potential operation unit 43 to select a potential operation time. As a result, the lamp of potential display unit 51 corresponding to the selected potential operation time is turned on. The user may operate power supply operation unit 42 and potential operation unit 43 before lying down on the front side of potential therapy device 10.

[0051] When a potential is generated in the potential generating area 21, the user's body is placed in the electric field on the front side of the potential generating area 21, and a potential is applied to the user's body. The user can check whether or not a potential is being applied to his or her body by touching his or her finger to the detection unit 39. If a potential is being applied to the body, the notification display unit 41 lights up. If a potential is not being applied to the body, the notification display unit 41 does not light up. This allows the user to know whether or not the potential treatment is being performed. If a potential is not being applied to the body, the user can reliably apply a potential to his or her body by changing the direction or position of the body. Since the control unit 30 is disposed at the corner of the upper end of the main body unit 20, even if the user changes his or her position by lying on his or her back or on his or her stomach, the head has a narrow range of movement and is therefore difficult to contact with the control unit 30. After that, when the set potential operation time has elapsed, the generation of the potential is automatically stopped by the potential control unit 47.

[0052] In cold seasons, the user can warm the main body 20 by operating the first heater operation unit 45. Specifically, the user can warm the main body 20 in advance before performing potential treatment, warm the main body 20 while performing potential treatment, or warm the main body 20 independently of potential treatment. When warming the main body 20 while performing potential treatment, the user can operate the second heater operation unit 46 to turn on the fluctuation mode and automatically fluctuate the temperature of the heater 22. This allows the user to receive potential treatment at a comfortable temperature.

[0053] When the user has finished using the electric potential therapy device 10, he or she operates the power supply operation unit 42 to turn off the power, and unplugs the power cord 31 from the outlet. With the above steps, use of the electric potential therapy device 10 is complete.

[0054] According to the embodiment configured as above, the following effects are achieved. The electric potential therapy device 10 of this embodiment includes a sheet-like main body 20. The main body 20 has an electric potential generating region 21 that generates an electric potential. The electric potential generating region 21 is provided on one side from the center of the main body 20. According to this configuration, the user lies down on the main body and places the head, which has a relatively small surface area, on the side where the electric potential generating region 21 is not provided, and the waist, which has a relatively large surface area, on the side where the electric potential generating region 21 is provided, thereby allowing a reliable application of an electric potential to the human body. By providing the electric potential generating region 21 biased toward the lower side of the main body 20, the amount of wiring for generating an electric potential can be reduced compared to the case where the electric potential generating region 21 is provided on the entire surface of the main body 20. Therefore, the manufacturing cost can be reduced. In addition, by placing the head on the side where the electric potential generating region 21 is not provided, the user can feel at ease that the head is not placed in an electric field. In addition, by placing the head on the side where the electric potential generating region 21 is not provided, the user can avoid discomfort caused by wiring, etc.

[0055] The electric potential therapy device 10 also has a notification unit 35. The notification unit 35 detects whether or not an electric potential is applied to the human body by contacting a part of the human body, and notifies the user that an electric potential is being applied to the human body when an electric potential is being applied to the human body. The notification unit 35 is provided integrally with the main body 20 and is disposed on the other side of the main body 20 from the center. According to this configuration, when the head, which has a relatively small surface area of ​​the human body, is placed on the side where the electric potential generating region 21 is not extended, the notification unit 35 is disposed in a position close to the head. Therefore, the user can easily check whether or not an electric potential is being applied to the body while lying on the main body 20.

[0056] Furthermore, the electric potential therapy device 10 has an electric potential manipulation unit 43 that manipulates the generation and stopping of the electric potential in the electric potential generating region 21. The electric potential manipulation unit 43 is provided integrally with the main body unit 20 and is disposed on the other side of the main body unit 20. According to this configuration, when the head is placed on the other side of the main body unit 20, the electric potential manipulation unit 43 is disposed in a position close to the head. Therefore, the user can easily manipulate the generation and stopping of the electric potential while lying on the main body unit 20.

[0057] Furthermore, the main body 20 has a heater 22 for warming the main body 20. According to this configuration, the user can warm the main body 20 to improve the comfort of use.

[0058] The electric potential therapy device 10 also has a heater control unit 48 that controls the heater 22. The heater control unit 48 heats the heater 22 at a first temperature H1 for a predetermined time T5 from when the heater 22 starts heating, and heats the heater 22 at a second temperature H2 lower than the first temperature H1 after the predetermined time T5 has elapsed. With this configuration, the temperature of the main body 20 drops slightly after the predetermined time T5 has elapsed from when the heater 22 starts heating. This allows the user to relax their body.

[0059] Before the application of the potential is stopped, the heater control unit 48 starts heating the heater 22. With this configuration, the main body unit 20 warms up before the application of the potential is stopped, so that the user can smoothly resume activities after the potential treatment is completed.

[0060] The heater control unit 48 gradually increases the temperature of the heater 22 before the application of the potential is stopped. This configuration provides a better feeling of use than if the temperature of the main body unit 20 were to suddenly increase before the application of the potential is stopped.
