FIG. 3 is a block diagram showing a schematic configuration of the low frequency treatment device 1. As shown in FIG. 1 to FIG. 3, the low-frequency treatment device 1 integrally includes a main body 10, a connecting portion 20, and conductor pads 30 a to 30 h. As shown in FIG. 3, the main body 10 includes a control unit 110, a signal generation unit 120, an output switching unit 130, a storage unit 140, an operation unit 150, and a power supply unit 160. Moreover, as shown in FIG. 2, the conductor pads 30a to 30h are connected to the output switching unit 130 via the conductors 31a to 31h, respectively. In addition, the location shown with the broken line of conducting wire 31a-31h and the output switching part 130 shows that it is the inside of the main body 10. FIG.

  As shown in FIG. 1, the main body 10 is provided with an operation unit 150 including buttons and the like on the surface. The operation unit 150 receives an operation by the operator, and outputs information such as power on / off switching, treatment mode selection, load intensity and frequency adjustment, and various settings to the control unit 110. In addition, the main body 10 includes each component other than the operation unit 150 inside. The main body 10 preferably has a certain degree of rigidity in order to protect the internal components, and is formed of, for example, ABS resin.

  The connection part 20 connects the main body 10 and the conductor pads 30a to 30h. Moreover, the connection part 20 is shape | molded by flat form (sheet shape), and has high flexibility as a whole, for example, is formed with a silicone resin etc. The connection part 20 is formed in the shape suitable for the specific site | part of a human body. In this example, as shown in FIG. 1, the connecting portion 20 is adapted to the stomach and waist of the human body and is formed in a shape that can be easily worn by being wrapped around. You may form in the shape suitable for.

  The connection part 20 is provided so that some conductor pads 30a-30h may be exposed from the back surface. The back surface of the connection part 20 has adhesiveness, and is comprised so that it may stick to the specific site | part of a human body. For example, a gel-like material such as hydrogel is provided on the back surface of the connecting portion 20. In addition, although the back surface of the connection part 20 does not need to have adhesiveness as a whole, the circumference | surroundings of the conductor pads 30a-30h have adhesiveness at least. As a result, when the low frequency treatment device 1 is used while being worn on the human body (hereinafter referred to as “when used” as appropriate), the conductor pads 30a to 30h are often attached to specific parts of the human body. The frequency current can be passed efficiently.

  The conductor pads 30 a to 30 h are arranged so as to be exposed from the back surface of the connecting portion 20. The conductor pads 30a to 30h are arranged apart from each other, and in this example, each of the conductor pads 30a to 30h has a super-elliptical shape having a plurality of openings. In use, the conductor pads 30a to 30h are electrodes for contacting a specific part of the human body and allowing a low-frequency current to flow through the human body, and are made of, for example, a conductive member such as silver or carbon. The lead pads 30a to 30h are configured so as to abut on a place where the muscles of a specific part of the human body can be efficiently moved during use. In addition, although eight conductor pads 30a-30h were shown in FIGS. 1-3, the conductor pad 30 should just be three or more. In addition, the conductor pad 30 is preferably as flexible as the connecting portion 20.

  The conducting wires 31a to 31h are members that are arranged on the back surface of the connecting portion 20 and electrically connect the conducting pads 30a to 30h to the output switching unit 130, respectively. The conducting wires 31a to 31h are arranged so as not to contact each other. In addition, the surfaces of the conducting wires 31a to 31h are electrically insulated so as not to energize the human body even if they are in contact with the human skin. The conducting wires 31a to 31h are formed of, for example, conductive silver ink.

  The control unit 110 is a processor that controls and manages the entire main body 10 including each functional block in the main body 10. The control unit 110 includes a processor such as a CPU (Central Processing Unit) that executes a program that defines a control procedure, and the program is stored in, for example, the storage unit 140 or an external storage medium. Specifically, the control unit 110 outputs a signal to the signal generation unit 120 and the output switching unit 130 based on various information input from the operation unit 150, and controls the operation of these functional blocks.

  The signal generator 120 is a circuit that generates a low-frequency current. As the low frequency current, a pulse current may be used, an alternating current may be used, or a pulse current and an alternating current may be selectively used. The waveform, amplitude, and the like of the low frequency current are determined based on a signal input from the control unit 110.

  Here, the low frequency current used in the low frequency treatment device 1 will be described. The low frequency current referred to in this specification is specifically a current obtained by modulating a high frequency carrier wave of about 2 kHz to about 5 kHz with a low frequency of less than 100 Hz, for example, 0.5 Hz to 80 Hz. The human body tends to conduct a high-frequency current of about 2 kHz to about 5 kHz. Therefore, the low frequency treatment device 1 can generate a low frequency current that easily conducts to the human body by using a high frequency of about 2 kHz to about 5 kHz as a carrier wave.

  The output switching unit 130 switches conduction / disconnection with the signal generation unit 120 of each of the conductor pads 30a to 30h, and the signal generation unit 120 with respect to the conduction pad (any one of 30a to 30h) in the conduction state. This is a circuit having a function of outputting the low-frequency current generated by. Further, the output switching unit 130 has a function of switching between grounding / non-grounding of the conductor pads 30a to 30h. As the output switching unit 130, for example, a full bridge circuit can be used.

  For example, it is assumed that only the conductor pad 30a is electrically connected to the signal generator 120 and only the conductor pad 30b is grounded by the output switching unit 130. If the maximum voltage of the low frequency current output from the signal generator 120 is 20V, the potential of the conductor pad 30a is 20V and the potential of the conductor pad 30b is 0V. Therefore, a current flows from the conductor pad 30a to the conductor pad 30b through the contacted human body. Thus, the output switching unit 130 can generate a low-frequency current between any pair of conductor pads 30.

  The storage unit 140 can be configured by, for example, a semiconductor memory or a magnetic memory. The storage unit 140 stores, in addition to the control order information 141, a program used for processing executed by the control unit 110.

  The control order information 141 is information including a plurality of pieces of information of a predetermined pair of conductor pads 30 in a predetermined order. When the control unit 110 reads the control order information 141, the control unit 110 selects a predetermined pair of conductor pads 30 while sequentially switching them in a predetermined order based on the control order information 141, and selects between the pair of conductor pads 30. The signal generator 120 and the output switching unit 130 are controlled so that a low frequency current is generated. Note that the control order information 141 may be provided for each treatment mode. The control order information 141 is preferably stored in advance in the storage unit 140.

  The power supply unit 160 supplies power to each functional block of the main body 10. The power supply unit 160 may include a battery such as a dry battery, for example, or may be supplied with power from a power system by a power line or wireless power feeding.

  Here, an operation example of the low frequency treatment device 1 will be described.

  The control unit 110 controls the signal generation unit 120 and the output switching unit 130 such that a low-frequency current is generated between any pair of conductor pads 30 among the conductor pads 30a to 30h. In addition, the control unit 110 selects a predetermined pair of conductor pads 30 in a predetermined order according to the control order information 141, and controls the low frequency current to be generated between the pair of conductor pads 30. . Specifically, for example, the following control is performed according to the set treatment mode.

  The control order information 141 includes information on a predetermined pair of conductor pads 30, such as a conductor pad 30a and a conductor pad 30b, a conductor pad 30b and a conductor pad 30c, a conductor pad 30c and a conductor pad 30d,. It is assumed that the information includes the conductor pad 30h and the conductor pad 30a in this order. According to such control order information 141, the control unit 110 selects a pair of adjacent conductor pads 30 while sequentially switching them in the circumferential direction, as shown in FIG. Control is performed so that a low-frequency current is generated between the pads 30. Therefore, when the low frequency treatment device 1 is attached to a specific part of the human body, the part to be stimulated is repeatedly changed in the rotation direction while locally stimulating the muscle of the attachment part. It can be moved efficiently and a high massage effect can be obtained.

  In addition, the control order information 141 includes information on a predetermined pair of conductor pads 30, such as a conductor pad 30a and a conductor pad 30e, a conductor pad 30b and a conductor pad 30f, a conductor pad 30c and a conductor pad 30g, It is assumed that the information includes the conductor pad 30d, the conductor pad 30h, the conductor pad 30a, the conductor pad 30e,. According to such control order information 141, the controller 110 selects a pair of opposing conductor pads 30 while sequentially switching from the outside to the center and from the center to the outside, as shown in FIG. Control is performed so that a low-frequency current is generated between the pair of conductor pads 30. Therefore, when the low frequency treatment device 1 is attached to a specific part of the human body, a stimulus that repeatedly changes the place to which the stimulus is applied from the central direction to the outer side (inside and outside direction) while stimulating the whole muscle of the wearing part. Because it will give, you can move the muscles efficiently and high massage effect is obtained.

  Further, the control unit 110 may control the potential difference between the pair of conductor pads 30 to be higher as the distance between the pair of conductor pads 30 that generate the low-frequency current is longer. Thereby, even if the space | interval of a pair of conductor pad 30 is long, it can suppress that the low frequency current to generate | occur | produce becomes small.

  Thus, according to the low frequency treatment device 1 according to the present embodiment, it can be handled easily and various stimuli can be given to a plurality of muscles without being remounted.

  FIG. 4 is a diagram showing an example in which the low frequency treatment device 1 is worn on the waist as a specific part of the human body. As shown in FIG. 4, since the connection part 20 and the conductor pads 30a-30h have flexibility, the low frequency treatment device 1 is closely attached so that it may wind around the waist. At this time, the conductor pads 30a to 30h are respectively arranged at locations suitable for moving the muscles by the low frequency current.
