In particular, the main body section includes 4 a built-in substrate, an electrical circuit mounted on the substrate, and the like. Circuit configuration of a low-frequency treatment device 20

[0022] Fig. Figure 2 is a diagram that schematically shows the internal configuration of the low-frequency treatment device. 20 illustrated according to the first embodiment. Referring to Fig. 2 closes the low-frequency treatment device 20 as a primary component, an operational section 201 , a display unit 202 , a control unit 203 (also referred to as the execution unit) including a central processing unit (CPU), a power generation unit 204including a pulse width modulation circuit (PWM circuit) 209 , a storage unit 206 , a communication unit 207 and a light-emitting diode (LED) unit 208 and an accelerometer 210 one. Although not illustrated, the low-frequency treatment device includes 20 A power supply is used to provide energy to each component. For example, an alkaline battery is used as the power supply. The power supply generates a control voltage that stabilizes the battery voltage and supplies it to each component.

[0023] The control unit 203 It typically includes a central processing unit (CPU) or a microprocessor unit (MPU). The control unit 203 It acts as a control unit that regulates the operation of each component of the low-frequency treatment device. 20controls it by storing it in memory 206 The control unit reads and executes the stored program. By executing the treatment program, the control unit generates 203 a PWM control signal (such as a voltage signal) according to the modified parameter and sends the generated signal to the PWM circuit 209 off. The control unit 203 It also functions as an execution unit, performing the prevention processing described below.

[0024] The storage 206 This is implemented through random access memory (RAM), read-only memory (ROM), flash memory, and the like. The storage unit 206 stores programs (including a treatment program) that are controlled by the control unit 203 data executed by the control unit 203 be used, and the like.

[0025] The operational section 201 For example, closes the switch48S and various switches for accepting user input into the low-frequency treatment device 20 one. If the user enters the operating section 201 The control unit is operated, receives 203 the content of the operation and controls each unit according to the received content of the operation.

[0026] The communication unit 207 includes a circuit for communication with the end device. 10 one. The communication unit 207 receives control information from the end device 10 and sends the control information to the control unit 203 The control information includes the parameters described above and a command that instructs the treatment program to be set with the parameters.

[0027] The power generation unit 204is a circuit that generates a current (hereinafter also referred to as treatment current) that is supplied by the pad 2 up to the area of ​​the user's body (especially the area to be treated). The PWM circuit 209 the power generation unit 204 It outputs a pulsed current with an amplitude, a relative duty cycle, and the like, as specified by the PWM control signal (i.e., the parameters), while keeping the pulsed current constant and adjusting the amount of output current according to the PWM control signal of the control unit. 203 adjusts the waveform to reflect the output of the treatment current from the power generation unit. 204 (hereinafter also referred to as treatment waveform) by the PWM control signal according to the parameter of the control unit 203It should be noted that the treatment current is not limited to a pulsed current; an alternating current can be used, or both types of current can be used selectively.

[0028] The output of the treatment current by the power generation unit 204 This includes, for example, a pulsed current with a low frequency. The pulse width of the treatment waveform with a low-frequency pulsed current can be, for example, approximately 100 µs for a short pulse width. The maximum pulse amplitude is also, for example, approximately 100 V. The current generation unit 204 The pulse waveform (amplitude, pulse width, cycle, and the like) can be changed according to the treatment program to provide different types of stimulation to the area, such as "massage", "tapping", "pressure", and "rubbing".

[0029] Additionally, the treatment content for the area can be modified (adjusted) by changing the parameters of the treatment program. In particular, changing the amplitude or pulse width of a pulse allows adjustment of the "intensity" (electrical stimulation intensity) of the stimulation, such as "massage," "tapping," "pressure," and "rubbing," and adjustment of the "speed" of the stimulation, such as "massage," "tapping," "pressure," and "rubbing."

[0030] The accelerometer 210 detects the acceleration of the low-frequency treatment device 20 The detected acceleration is transmitted to the control unit. 203 entered. End device configuration 10

[0031] Fig. Figure 3 is a configuration diagram of the end device 10 according to the first embodiment. Referring to Fig. 3 closes the end device 10 as the main component a CPU 152, a working memory 154 , an operating unit 156 , which allows the user to operate the end device 10 receives an ad 158 , a communication unit 160 for wireless communication via an antenna 162 , a storage interface ( I / F ) 164 , a communication interface ( I / F ) 166 , a loudspeaker 168 for audio output and a microphone 170 for voice input.

[0032] The CPU 152 Each unit is controlled by executing the commands in the working memory. 154 saved programs.

[0033] A memory area of ​​the memory 154 It can be composed of RAM, ROM, flash memory, a hard disk device, and / or the like. Programs that run on the CPU 152 data executed by the CPU 152 are used and the like are stored in RAM154 saved.

[0034] The operational section 156 receives an operator input at the end device 10 The operational section usually closes 156 a touch panel. The touch panel is on the display. 158 planned. The operational section 156 This may include a switch button and the like.

[0035] The communication unit 160 connects to a mobile communications network via the antenna 162 and transmits and receives signals for wireless communication. Accordingly, the terminal device can 10 with other communication devices (for example, the server) 30 and other terminal devices 10 ) communicate via a mobile communications network, such as Long-Term Evolution (LTE).

[0036] The memory interface 164 reads data from an external storage medium 165The CPU 152 reads the data that is in the storage medium 165 are stored via the memory interface 164 and stores the data in the working memory 154 The CPU 152 reads the data from the main memory 154 and stores the data on the external storage medium 165 via the memory interface 164 .

[0037] The storage medium 165 may include a medium that stores programs or data in a non-volatile manner, such as a Compact Disc (CD), a Digital Versatile Disc (DVD), a Universal Serial Bus (USB) storage device, and a Secure Digital (SD) memory card.

[0038] The communication interface ( I / F ) 166 is achieved through an adapter, connector or the like to enable communication between the end device 10 and the low-frequency treatment device 20to control. In the present embodiment, BLE is used as the communication method. However, the communication method can be a wireless communication method, such as a wireless LAN, or a wired communication method using a Universal Serial Bus (USB) or the like. Application position of a low-frequency treatment device 20

[0039] The following describes the position on the user's body where the pad should be placed. 2 the low-frequency treatment device 20 The position where a low-frequency current is applied to the user's body is referred to as an "application position". The application position includes a position where a low-frequency current is applied from one pad of the set of pads. 2 is output and a position where the low-frequency current connects to the other pad of the set of pads. 2after passing through the user's body. That is, the application position can also be described as a position through which a low-frequency current flows. The application position can also be described as a position where one of the pads of the set of pads is located. 2 appropriate.

[0040] If the pulse width of the treatment current is kept at a relatively low value (for example, 60 µs) and the pads 2 the low-frequency treatment device 20 attached to the intended position specified by the manufacturer of the low-frequency treatment device 20As intended, this allows for the execution of a low-frequency treatment that does not contract the user's muscles and has a high therapeutic effect. However, if the application position differs from the intended position, the output of the treatment current by the low-frequency treatment device may be impaired. 20 This causes the application area to vibrate. This vibration is also referred to as fluttering. For example, if the application area is located on the skin over a muscle, it tends to vibrate.

[0041] If the application device vibrates, the user's actions are hindered. For example, if the application device is the user's foot or leg and it vibrates, the user will walk with the vibrating device, thus hindering their walking motion.

[0042] Thus, the low-frequency treatment device 20 A preventive processing mechanism is used to prevent vibrations at the application position. The preventive process of the present first embodiment is a process for notifying the user of a change in the application position of the pad. 2 Furthermore, the accelerometer detects 210 In the present embodiment, the acceleration due to vibrations of the user's application position and the acceleration of the application position due to the user's action (for example, user running).

[0043] Furthermore, when the application position vibrates, the pad is located 2 in contact with the application position, so that the vibration is also transmitted to the main body section 4 is transmitted. Accordingly, the accelerometer 210 , which is internal to the main body section 4The acceleration provided is due to the transmitted vibration (acceleration of the low-frequency treatment device). 20 ) than the acceleration due to the vibration of the application position. Processing of the treatment system 1

[0044] Fig. Figure 4 illustrates the processing flow of the treatment system. 1 If the user starts the operation of the low-frequency treatment using the low-frequency treatment device 20 Once the processing is complete, it begins. Fig. 4.

[0045] First, in step S1 , a treatment current is applied from the electrode. Subsequently recorded, in step S2 , the accelerometer 210 an acceleration α of a low-frequency treatment device 20 as the acceleration α of the application position. Then determined, in step S4 , the control unit 203The system detects whether the measured acceleration α is higher than a predefined threshold Th. If the acceleration α is higher than the threshold Th, this means that the application position is vibrating (fluttering). If the acceleration α is equal to or less than the threshold Th, this means that the application position is not vibrating.

[0046] If in step S4 NO is determined, i.e., it is determined that the application position does not vibrate, the processing of the low-frequency treatment device does not move. 20 Continue to step S7 In step S7 determines the control unit 203 Whether a predetermined time period has elapsed since the user initiated the low-frequency treatment. The "predetermined time period" refers to the duration from the execution of the start operation during which the application position does not flutter, for example, 10 seconds. In step S7The processing of the low-frequency treatment device 20 The process stops when the predetermined time period has elapsed. Similarly, it returns to step 1. S7 the processing of the low-frequency treatment device 20 to step S2 return if the predetermined time period has not been determined to have elapsed. If in step S4 YES, it is determined, i.e., it is determined that the application position vibrates, the processing of the low-frequency treatment device moves. 20 Continue to step S6 .

[0047] In step S6 The control unit generates 203 Vibration information indicating that the acceleration α is higher than the threshold Th, i.e., the application position is vibrating. In step S6 The control unit sends 203 the vibration information to the end device 10 .

[0048] In stepS8 The terminal device receives 10 the vibration information. In step S10 causes the end device 10 the ad 158 to display change information indicating that the application position where the pad is located 2 It is appropriate to change it.

[0049] Fig. Figure 5 illustrates an example of the change information displayed on the screen. 158 is displayed. In the example of Fig. 5, the change information includes the text "Adjust pad position". In this way, the low-frequency treatment device 20 a processing operation to cause the display 158 the end device 10 The text "Adjust pad position" is displayed, as well as the option to edit and notify about a change in the position where the pad is attached.

[0050] Accordingly, the low-frequency treatment device causes 20 of the first embodiment, that the display 158 the end device 10 The text "Adjust pad position" is displayed as a preventative measure when a vibration is detected from the pad's application position. 2 is detected. Thus, the control unit can 203 The user is prompted to adjust the position of the pad. The user can then adjust the position of the pad to prevent vibration (fluttering) of the application on the user's body.

[0051] The accelerometer 210 and the pad 2 , which can be attached to the user's body, are used in the same device (the low-frequency treatment device). 20 ) provided. Accordingly, the accelerometer can 210 the vibration of the pad's application position 2than the vibration of the low-frequency treatment device 20 This allows the accelerometer to detect the data. 210 the acceleration of the pad's application position 2 capture precisely.

[0052] The accelerometer 210 The present embodiment does not require a dedicated accelerometer to clearly detect the acceleration of the user's position due to vibrations, as opposed to the acceleration of the user's position due to the user's action (for example, the user walking). This means that the relatively inexpensive accelerometer 210 can be used. For example, consider the case where the user is walking while receiving a low-frequency treatment and the accelerometer 210An acceleration due to walking is detected, even though the application position is not vibrating. In this case, even if the application position is not vibrating, a false positive notification of change information may be issued. However, in the present embodiment, as described in step S7 from Fig. Step 4 illustrates the processing of step S2 , Step S4 and step S6 The operation is executed as long as the predetermined time period from the start of operation has not elapsed, and it is not executed after the predetermined time period has expired. The "predetermined time period" refers to the period from the execution of the start operation during which the application position does not flutter. In this way, the low-frequency treatment device can 20 by executing the processing of step S7 , prevent such false positive notifications.

[0053] Furthermore, the "processing to notify of a change in application position" can be a different type of processing. An example of such a different processing includes processing to display the change information on a display section (not illustrated) of the low-frequency treatment device. 20 One example of alternative processing includes processing to output a tone that conveys the change information from the end device. 10 and / or the low-frequency treatment device 20 indicates one. Second embodiment

[0054] A second embodiment is then described. Fig. 6A and Fig. Figure 6B shows diagrams illustrating the appearance of a low-frequency treatment device. 600 Illustrate according to the second embodiment. Fig. Figure 6A illustrates the side of the low-frequency treatment device.600 with electrodes. Fig. Figure 6B illustrates the side of the low-frequency treatment device. 600 opposite the in Fig. Page 6A illustrated.

[0055] Referring to Fig. 6A closes the low-frequency treatment device 600 a rectangular element 602 with a rectangular shape. The direction of extension (longitudinal direction) of the rectangular element. 602 The x-direction is the x-direction and the y-direction is the latitude direction. A number N (N is an integer of two or higher) of pairs of electrodes (positive electrode and negative electrode) is placed in the rectangular element. 602 arranged. In the following, a pair of electrodes will also be referred to as an "electrode pair".

[0056] In the example of Fig. 6A shows the two electrodes of the electrode pairs arranged in the Y-direction. The electrode pairs are arranged in the X-direction. It should be noted that the arrangement of the two electrodes of the electrode pairs and the arrangement of the electrode pairs are not limited to this arrangement and a different arrangement may be used in modified examples.

[0057] The low-frequency treatment device 600 includes a number N of electrode pairs 401 , 402 , ..., 40N one. Also, the one in Fig. 6A illustrated surface a mounting surface 602A , which can be attached to the user's body. Any technique can be used to attach the device. 602A to be attached to the user's body. For example, a section or the entire attachment surface can be 602AIt must be adhesive. Any technique can be used to impart adhesive strength. For example, a section or the entire fastening surface can be coated. 602A The section with adhesive properties can be the area. Alternatively, an adhesive element with adhesive properties can be applied to a section of the entire mounting surface. 602A be provided. The mounting surface 602A the low-frequency treatment device 600 can be attached to the user's body through adhesion.

[0058] Furthermore, a technique for attaching the mounting surface can be used. 602A The use of a fastening element on the user's body includes the use of a fastening element. The fastening element could, for example, be a suction cup attached to the user's body. The low-frequency treatment device 600It can include a pair of fasteners at both ends of the rectangular element. The pair of fasteners can be, for example, Magic Tape (trade name) or another type of hook and loop fastener. The user can then attach the low-frequency treatment device. 600 by, for example, wrapping it around his wrist or ankle and tying the pair of fasteners together at the ends.

[0059] The number N of electrodes also includes a first electrode pair. In the example of Fig. 6A is an electrode pair 401 the first pair of electrodes. The markings are also located there. 606 at positions where the electrode pair 401 is provided internally. The marking 606 It can be any marking, and in the example of Fig. 6A is a black dot. If the treatment is performed using the low-frequency treatment device... 600When the treatment begins, a current is delivered through the first pair of electrodes. The user can see the markings. 606 Align with the desired low-frequency treatment position and the low-frequency treatment device 600 attach to the body.

[0060] Also, as in Fig. 6B illustrates a main body section 604 on a parking space 602B on the side opposite the mounting surface 602A the low-frequency treatment device 600 arranged.

[0061] Fig. Figure 7 is a diagram that schematically shows an internal configuration of the low-frequency treatment device. 600 illustrated according to the second embodiment. The difference between the drawings Fig. 7 and Fig. 2 is that in Fig. 2 an electrode pair is present, while in Fig. 7. A number N of electrode pairs are present. Furthermore, by controlling the power generation unit 204 , the control unit 203 The electrode pairs used to deliver the treatment current are activated sequentially. In other words, by controlling the current generation unit, the treatment can be... 204 the control unit 203 sequentially activate the positive electrodes, which supply the treatment current of the N number of electrode pairs. 401 , 402 , ..., 40N spend.

[0062] Fig. Figure 8 is a diagram that schematically illustrates the processing flow of the low-frequency treatment device. 600 as illustrated in the second embodiment. When the user starts the operation of the low-frequency treatment using the low-frequency treatment device. 600 Once the processing is complete, it begins. Fig. 8.

[0063] First, in step S11, the low-frequency treatment device 600 a treatment current is applied using the first electrode pair. This is then recorded in step S12 , the accelerometer 210 an acceleration α of the low-frequency treatment device 600 than the acceleration α of the application position due to the first electrode pair.

[0064] In step S 14, the control unit determines 203 The system detects whether the measured acceleration α is higher than a predefined threshold Th. If the acceleration α is higher than the threshold Th, this means that the application position vibrates (flutters) due to the first electrode pair. If the acceleration α is equal to or less than the threshold Th, this means that the application position does not vibrate due to the first electrode pair.

[0065] If NO is determined in step S 14, i.e., if it is determined that the application position is determined to be non-vibrating due to the first electrode pair, the processing of the control unit moves 203 Continue to step S18 In step S18 determines the control unit 203 Whether a predetermined time period has elapsed since the user initiated the low-frequency treatment. The "predetermined time period" refers to the duration from the execution of the start operation during which the application position does not flutter, for example, 10 seconds. In step S18 Processing will be stopped if the control unit 203 determines that the predetermined time period has elapsed. Likewise, in step 1, the process returns to the previous step. S18 the processing of the control unit 203 to step S12 return when the control unit 203determines that a predetermined time period has not elapsed. If in step S14 YES, it is determined, i.e., it is determined that the application position vibrates due to the first electron pair, and the processing of the control unit moves. 203 to step S16 .

[0066] In step S16 The control unit changes 203 from the electrode pair used to deliver a treatment current to the next electrode pair. The electrode pair after the change is used to deliver a treatment current. That is, if in step S16 YES, step by step S14 The control unit is determined 203The output of a treatment current from the electrode pair delivering the treatment current stops, causing the next electrode pair to begin delivering a treatment current. Similarly, "next electrode pair" refers to the electrode pair with a reference number one higher than that of the electrode pair that delivered the treatment current. For example, if YES for step S14 The electrode pair that delivers the treatment current is determined, for example, by switching from the electrode pair 402 , which has delivered the treatment current, to the next pair of electrodes 403 If the processing of step S16 When the processing of the control unit ends, it returns to normal. 203 to step S12 back.

[0067] In step S12 The control unit detects 203 an acceleration α of the low-frequency treatment device 600as vibration of the application position because the electrode pair to step S16 changes. When the processing of step S12 ends, the control unit 203 the processing of step S14 and step S16 The processing loop of step S12 , Step S14 and step S16 ends when at step S14 NO is determined. If at step S14 If NO is determined, this means that the acceleration of the application position is due to the electrode pair to which in step S16 The value changed is equal to or less than the threshold.

[0068] In this way, when a vibration of the application position is detected due to the electrode pair, the low-frequency treatment device switches. 600In the second embodiment, the electrode pair used for the output of the low-frequency current serves as a preventative measure. Accordingly, vibration of the application position can be prevented without the user having to adjust the low-frequency treatment device. 600 It moves. This improves user comfort.

[0069] Likewise, in this step, the change changes S16 the low-frequency treatment device 600 from the electrode pair before switching to the electrode pair that is nearby. Accordingly, the low-frequency treatment device 600 Apply a treatment current to a position as close as possible to the desired position of the user. This allows the low-frequency treatment device to function even if the electrode pair delivering the treatment current is changed. 600 to minimize user dissatisfaction. Third embodiment

[0070] A third embodiment is then described. The appearance and internal configuration of the low-frequency treatment device of a treatment system of the third embodiment are similar to those described in the Fig. 1 and Fig. 2 are illustrated. Fig. 9 is a diagram that schematically shows an internal configuration of the low-frequency treatment device. 20 illustrated according to the third embodiment.

[0071] The processing of step S21 , Step S22 and step S24 is the same as the processing of step S1 , Step S2 and step S4 from Fig. 4. If YES in the processing of step S24 Once determined, the processing moves on to step S26 . At step S26The treatment current output is modified to eliminate vibration at the application position. In step S26 For example, processing is performed to control the application of the low-frequency current in order to reduce the intensity of the low-frequency treatment. For example, the waveform of the low-frequency current includes three parameters: amplitude, pulse width, and pulse frequency. By changing at least one of these three parameters, the intensity of the low-frequency treatment can be reduced. For example, reducing the amplitude decreases the intensity of the low-frequency treatment.

[0072] In this way, if a vibration of the application position is caused by the pad 2 The low-frequency treatment device is detected 20In the third embodiment, as a preventive processing function, processing is performed to control the application of the low-frequency current in order to reduce the intensity of the low-frequency treatment. This can prevent vibration (fluttering) of the application position on the user's body. Other embodiments

[0073] (1) The embodiments described above may include a first mode and a second mode selectable by the user. In the following description, prevention processing is any of the prevention processing operations described in the first to third embodiments. The first mode is a mode in which prevention processing is performed when a vibration is detected. The second mode is a mode in which prevention processing is not performed when a vibration is detected. For example, the mode selection of the operating section 156the end device 10 received by a second receiving unit.

[0074] Fig. Figure 10 illustrates an example of a mode selection screen in the case where prevention processing is used to notify about change information. In the example of Fig. In step 10, a notification mode is displayed as the first mode, and a notification-off mode is displayed as the second mode. The notification mode is a mode in which change information is notified when the application vibrates. The notification-off mode is a mode in which no change information is notified when the application vibrates.

[0075] By moving a cursor 158A The user can set the mode to notification mode or notification-off mode.

[0076] For example, a user who wants to be notified of change information when the application vibrates can set the mode to the first mode. A user who does not want to be notified of change information when the application vibrates can set the mode to the second mode if they find the change information notification annoying.

[0077] This allows the user to select the mode, further improving user comfort.

[0078] (2) In the embodiments described above, the threshold value Th a preset value. The threshold. Th However, this can be configured by the user. For example, the mode selection of the operating section can be changed. 156 the end device 10 can be received by a first receiving unit.

[0079] For example, a user who is not bothered by slight fluttering can set the threshold Th Set it to a high value. A user who is bothered by slight fluttering can lower the threshold. Th set to a low value. Fig. 11 is a diagram illustrating an example of an input screen where the threshold Th The input screen will appear on the display. 158 displayed. This setting can be, for example, from the operating section. 201 or the actuation section 156 be received. Such a configuration allows the user to set the threshold. Th to adjust. This will further improve user comfort. Modified example

[0080] (1) In the embodiments described above, vibration (flutter) of the application position is detected by the accelerometer. 210However, vibrations of the application position can be detected by a different device. For example, the vibration of the application position can be detected using a myoelectric sensor that captures the action potential when muscles contract. A configuration can be used in which, if the action potential of the application position is determined to be equal to or higher than a predetermined threshold, the application position is determined to be vibrating. In another possible configuration, an action potential pattern is obtained in advance as a vibration pattern for when muscles or the like are vibrating, and if the action potential pattern of the application position is similar to or equal to the vibration pattern, the application position is determined to be vibrating.Likewise, the myoelectric sensor can be provided integrally with the low-frequency treatment device (in the same case) or can be provided separately from the low-frequency treatment device (in a different case).

[0081] Furthermore, the control unit can detect vibration of the application position using both the myoelectric sensor and the accelerometer. For example, if vibration of the application position is detected by both the myoelectric sensor and the accelerometer, the control unit determines 203 that the application position vibrates. The control unit 203The device determines that the application position does not vibrate if vibration of the application position is detected by either the myoelectric sensor or the accelerometer, or if vibration of the application position is not detected by either the myoelectric sensor or the accelerometer. Furthermore, another device can be used in conjunction with the myoelectric sensor and the accelerometer to detect vibration of the application position.

[0082] In this way, the accuracy of detecting a vibration of the application position can be improved by using two or more devices that detect a vibration of the application position.

[0083] (2) The accelerometer described above detects the acceleration due to vibration of the user's application position and the acceleration of the application position due to the user's action (for example, the user walking). That is, the accelerometer described above detects the acceleration due to a small movement and the acceleration due to a large movement. However, an accelerometer of a modified example can detect the acceleration of a small movement (vibration of the user's application position) without detecting the acceleration due to a large movement (user action) through filtering or the like. Using such an accelerometer, the low-frequency treatment device described above can be used regardless of whether the user is walking or not.

[0084] (3) The low-frequency treatment device of the present embodiment, described above, is of the cordless type. However, the low-frequency treatment device can also be of the wired type. Furthermore, the accelerometer described above is integrated internally in the main body section. 4 provided. However, the accelerometer can be mounted externally on the main body section. 4 be provided. In such a configuration, the acceleration sensor's acquisition results are sent to the main body section. 4 sent via a wired or wireless connection.

The scope of protection of the present invention is not defined by the above descriptions, but by the claims, and it includes all meanings equivalent to the scope of protection and modifications within that scope.
