Description

Technical Field

[0001] The present invention relates to a technique for promoting the treatment of organs by passing a weak electric current through them.

Background Art

[0002] Conventionally, treatment devices that pass an electric current through organs have been widely used. For example, for the heart, there are defibrillators used for the treatment of ventricular fibrillation and ventricular tachycardia, and pacemakers used for the treatment of some abnormal heart rhythms. Also, although different from organs, low-frequency therapeutic devices that apply a low-frequency electric current to relieve various muscle pains, recover fatigue, and promote blood circulation may be used. The above-mentioned treatment devices pass an electric current that can contract myocardial and skeletal muscles. However, recently, the therapeutic effect of a weaker electric current has also been attracting attention. For example, Patent Document 1 discloses a method of directly attaching an electrode to the heart and a method of arranging an electrode on the skin at the heart site in order to "transmit a minute electric current to the heart that may be restored by the minute electric current". The minute electric current is supposed to use 0.001 to 10 mA.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Treatment using a weak electric current within a range that does not contract myocardial and skeletal muscles is very useful because it does not cause pain to the patient. However, when applying such a treatment method, taking an invasive method of directly attaching an electrode to the heart will undermine the advantage of being painless. Therefore, treatment using a weak electric current is preferably performed by a method of attaching an electrode outside the body. However, while research has been conducted on the therapeutic effects of microcurrents, methods for treating deep organs using external electrodes have not been considered. Similar challenges exist for organs other than the heart. In view of these challenges, the present invention aims to provide a technology that promotes the treatment of organs by applying a microcurrent. [Means for solving the problem]

[0005] The present invention A microcurrent therapy device that applies electric current to the organ to be treated via transcutaneous current to the user's body, A conductive patch to be attached to the skin of the human body, It has a main unit connected to the patch and for supplying power, The aforementioned main unit is An input unit for inputting predetermined information regarding the user's body composition, A microcurrent therapy device can be provided, comprising a current control unit that controls the current of the current supply according to the body composition, so as to supply a weak current to the aforementioned organ that does not affect the movement of the said organ.

[0006] When an electric current is passed through the human body from outside, the current is attenuated by the body composition, such as the skin and muscles. According to the present invention, information about body composition can be input and the current can be controlled accordingly, so that even if the current is attenuated by body composition, a desired weak electric current can be delivered transcutaneously to the organs.

[0007] Information regarding body composition can include any information that affects current attenuation, such as height, weight, and the size of each body part. In addition to information that directly affects current attenuation, information that can be statistically recognized as having an influence on current attenuation, such as gender and age, may also be used. Information regarding body composition may be entered each time the device of the present invention is used, or it may be pre-entered and saved, and the device of the present invention may read it as needed. Furthermore, the information may be entered by operating the device of the present invention, or it may be entered using an external device such as a computer, smartphone, or server and read from there. The method for controlling the current may involve calculating the attenuation rate of the current from the skin to the organs based on information about body composition, and controlling the current flow based on this. Alternatively, the correlation between information about body composition and the current flowing through the skin and the current flowing through the organs may be determined in advance through experiments or analysis, and the current flow may be controlled using these results. Furthermore, since the impedance of the skin, subcutaneous tissue, and target organs changes with the application of current, the amount of current may be adjusted to reflect these changes. In this invention, the organs can be, for example, the heart, lungs, liver, kidneys, pancreas, brain, intestines, etc. Any one of these organs may be targeted, or multiple organs may be targeted.

[0008] In the present invention, The input unit may also receive information about the organs.

[0009] Information regarding organs can include the type of organ, its location, and its size. For example, a user could obtain the necessary information in advance from a medical institution or similar facility and input it into the present invention. The information to be input may vary depending on the type of organ. Information about organs, like information about body composition, can be entered in various ways.

[0010] In the present invention, The main unit includes an impedance detection unit that detects impedance when power is supplied, The current control unit may control the current according to the impedance.

[0011] The state of electrical conduction to organs is affected by impedance. According to the above embodiment, appropriate electrical conduction to organs can be achieved by using the impedance detection results. In the above embodiment, since the impedance changes depending on the frequency of the current, it is preferable to detect it at multiple frequencies. When energizing an organ with a predetermined pulse, it is preferable to detect the impedance at the frequency included in that pulse. Impedance can be detected using various methods. For example, impedance can be calculated by using a patch used for energization and detecting the actual current flow when a predetermined current is passed through it.

[0012] In the present invention, The electrical current supplied by the main unit may be applied within a range that allows the weak current to reach the organ, and within a range that does not cause contraction of the skeletal muscles between the patch and the organ.

[0013] According to the above embodiment, since it does not cause skeletal muscle contraction, the user can use the device of the present invention without feeling pain or discomfort. The above control can be carried out in various ways. For example, an upper limit of the current that does not cause skeletal muscle contraction may be stored in advance in relation to body composition, and the current supply may be controlled within this range. This upper limit may be changed depending on the body part. Alternatively, the upper limit may be a value determined for a typical user, or it may be set through an electrical test or the like when a user uses the device of the present invention for the first time.

[0014] In the present invention, The aforementioned information regarding body composition may include body fat percentage.

[0015] Body fat percentage is an indicator that has a relatively large impact on the body's impedance. Therefore, inputting body fat percentage can improve the accuracy of estimating the attenuation of electrical current from the skin to the organs. However, as described above, the information regarding body composition can be arbitrarily determined, and the body fat percentage is not necessarily essential.

[0016] When using the body fat percentage, the main body device includes a body fat percentage measurement unit that measures the body fat percentage, the input unit may input the body fat percentage measured by the body fat percentage measurement unit.

[0017] By doing so, the body fat percentage can be accurately input. The body fat percentage can be measured by various methods. For example, a method of measuring the body fat percentage by measuring the current actually flowing through an energization patch may be adopted.

[0018] In the present invention, the energization control unit may control the current according to the organ.

[0019] According to the above aspect, even when targeting a plurality of organs, an appropriate current can be passed according to the type of organ.

[0020] In the present invention, when it is detected that the patch has reached a predetermined temperature or higher, the energization may be cut off.

[0021] In the present invention, in order to reach a desired weak current to the organ even when attenuated by body composition, the voltage and current when energizing from outside the body may be relatively high. According to the above aspect, since the current can be cut off when the patch reaches a predetermined temperature or higher, abnormal current flowing through the body can be avoided and safety can be enhanced. The reference temperature in this case can be arbitrarily set, and in addition to being a fixed value in advance, it may also be set by the user. As a method for detecting the temperature of the patch, for example, a temperature sensor may be provided on the patch. Also, the temperature may be calculated based on the change in current when a predetermined voltage is applied to the patch.

[0022] In the present invention, The organ used is the heart. The current supplied to the main unit may be 1 to 60 mA.

[0023] The current mentioned above refers to the current output by the main device, i.e., the current flowing through the skin. In the case of the heart, it is statistically expected that the current will be attenuated to approximately 1 / 10 of the original current. Therefore, a current of about 0.1 to 6 mA will flow through the heart. Within this current range, a weak current that is painless and can be expected to have a therapeutic effect can be applied to the heart. From the perspective of obtaining a more effective result, it is also preferable for the current supplied by the main device to be 30 to 60 mA. While the heart was used as an example, an appropriate current range can be determined for other organs as well.

[0024] In the present invention, The patch may be shaped to cover 80% or more of the projected area of ​​the organ on the body surface.

[0025] This allows for effective electrical current delivery to the entire organ. Since the sizes mentioned above vary depending on the type of organ and the user's physique, it is preferable to select the appropriate patch from several types. For example, users could have the appropriate patch selected for their target organ at a medical institution.

[0026] In the present invention, At least two of the aforementioned patches may be connected to the main device by cables of a length that allows them to be attached to the front and back surfaces of the human body, with the organs in between.

[0027] In this invention, the number of patches used and their placement during use can be determined arbitrarily. However, in order to effectively deliver electricity to an organ, it is preferable to attach the patches to the front and back surfaces of the human body, with the organ in between. According to the above embodiment, since the patch and the main device are connected by a cable of sufficient length, ideal application can be achieved, and effective electrical stimulation to the organs can be realized.

[0028] The present invention does not necessarily have to possess all of the above-described features; some may be omitted or combined as appropriate. Furthermore, in addition to being configured as a microcurrent therapy device, it can also be configured as a microcurrent therapy method. In other words, This is a microcurrent therapy method in which an electric current is passed through the skin to the organ to be treated in the user's body. (a) The step of preparing an electrically conductive patch to be attached to the skin of the human body, (b) A step of inputting predetermined information regarding the user's body composition, (c) A microcurrent therapy method may also be provided, comprising the step of applying a weak electric current to the organ from a main unit connected to the patch, in accordance with the body composition, such that it does not affect the movement of the organ. By doing so, it becomes possible to achieve therapeutic effects using weak electric currents. The various characteristics described for microcurrent therapy devices can also be applied to microcurrent therapy methods.

[0029] The present invention may further be configured as a control method for controlling the flow of electricity in a microcurrent therapy device, a computer program for implementing this method on a computer, and a computer-readable recording medium on which such computer program is stored. [Brief explanation of the drawing]

[0030] [Figure 1] This is an explanatory diagram showing the configuration of the microcurrent therapy device of the embodiment. [Figure 2] This is an explanatory diagram illustrating an example of the therapeutic effect of microcurrent therapy. [Figure 3] This is an explanatory diagram illustrating an example of the therapeutic effect of microcurrent therapy. [Figure 4] This is a flowchart of the power supply control process. [Modes for carrying out the invention]

[0031] The following describes embodiments of the present invention, using a microcurrent therapy device that treats or improves the health of organs by applying a weak electric current to them. The organs can be, for example, the heart, lungs, liver, kidneys, pancreas, brain, intestines, etc. One of these may be targeted, or multiple organs may be targeted.

[0032] Figure 1 is an explanatory diagram showing the configuration of a microcurrent therapy device according to an embodiment. In the microcurrent therapy device of this embodiment, a patch 1 attached to the human body is connected to the main unit 10 by a cable 3. The example in the figure illustrates the application of current to the heart, but the microcurrent therapy device can also be used to treat other organs.

[0033] Patch 1 is an electrode that adheres to the skin. It can be made of a conductive resin or the like. In this embodiment, two patches are used, one on the front and one on the back of the body, sandwiching the organ, but the number of patches can be determined arbitrarily. The shape and size of patch 1 can be determined arbitrarily, but in this embodiment, it was sized to cover at least 80% of the projected area of ​​the target organ on the body. For example, in the case of the heart, as shown in the figure, the approximate projected area on the front and back surfaces of the body can be determined, so it is sufficient to cover at least 80% of that area. Since the projected area of ​​an organ varies depending on the type of organ and the user's physique, it may be advisable to prepare multiple types of Patch 1 so that users can select the appropriate one as needed. Users can then have a medical institution or other facility select the appropriate size Patch 1 for each organ. When using the microcurrent therapy device of the embodiment on multiple organs, a different patch 1 will be used for each organ. In this case, to make it easy to distinguish between patches 1, for example, the name of the target organ may be written on patch 1. Alternatively, the shape of patch 1 may be the shape of the organ in question.

[0034] Patch 1 may be equipped with a temperature sensor so that the temperature can be detected by the main unit 10. By doing so, safety can be improved by controlling the power supply to be cut off when the temperature of Patch 1 exceeds a predetermined level, thereby preventing abnormal current from flowing.

[0035] Cable 3 is an electrical wire that conducts current between Patch 1 and the main unit 10. It is long enough to allow Patch 1 to be attached to both the front and back surfaces of the body, flanking the organs. For example, each cable 3 can be approximately 50cm to 1m long. Multiple lengths of cable 3 can be prepared and used depending on the organ.

[0036] The main unit 10 is a device that delivers electricity to the human body via patch 1. The main unit 10 is equipped with a display 11 used for inputting and outputting various information. Switch 13 is used for operations such as turning the power on / off and starting / stopping the power supply. Switch 14 is a menu switch for selecting the operation content of the main unit 10. Switch 12 is used to instruct the input and selection of various information according to the menu.

[0037] The information entered into the main unit 10 includes information about the user's body composition. For example, it includes the user's gender, age, height, weight, and body fat percentage. Depending on the organ being treated, the user may also be required to input the size of various body parts. The information to be entered includes information about organs. For example, this could include the type of organ, its location, and its size. For instance, the user could obtain the necessary information in advance from a medical institution or similar facility and input it into the present invention. The information to be entered may vary depending on the type of organ. This information can also be entered by operating the main unit 10. Furthermore, the main unit 10 can be connected to a computer PC wirelessly or via a wired connection, and this information can be transmitted from the computer PC to the main unit 10. In addition to a computer PC, information may also be transmitted to the main unit 10 via a smartphone, server, or other means.

[0038] The main unit 10 also has a body fat percentage measurement function. After selecting the body fat percentage measurement function from the menu using switch 14 and attaching patch 1 to the designated location, the main unit 10 sends an electric current to patch 1 to measure body fat percentage, and the body fat percentage is calculated based on the measurement result.

[0039] Furthermore, the main unit 10 can also be configured to set an upper limit for use. In this embodiment, it is desirable to apply a weak current that does not cause pain or discomfort to the user, so it is preferable to set an upper limit for the current that can be applied. Since the current value at which pain or discomfort is felt varies from user to user, it is preferable that the user be able to set the upper limit themselves. In this embodiment, the current applied from patch 1 is gradually increased, and when the user feels pain, they can input this information to the main unit 10 to set the upper limit. Alternatively, the upper limit may be set in advance to a predetermined value.

[0040] The main unit 10 is equipped with a control unit 20 that controls its operation. In this embodiment, the control unit 20 is constructed in software by installing computer programs that realize each of the illustrated functions on a microcomputer having a CPU and memory. It is also acceptable to construct each of the functions in hardware.

[0041] The input unit 21 provides various inputs to the main unit 10 as described earlier. The transmitting / receiving unit 22 transmits and receives information with external devices such as a computer PC. The power supply control unit 23 controls the supply of electricity from the main unit 10 to the human body through patch 1. The data storage unit 24 stores various information input to the main unit 10, and also stores the power supply history of the main unit 10. The body fat percentage measurement unit 25 detects the power supply from the main unit 10 to patch 1 and the resulting current value, and performs the function of measuring the user's body fat. The impedance detection unit 26 detects the impedance for each frequency by applying current from the main unit 10 to patch 1 at various frequencies and detecting the corresponding current values. The detected impedance is then used by the power supply control unit 23 for power supply control.

[0042] The microcurrent therapy device of the embodiment, with the configuration described above, can deliver a weak electric current to organs to treat them or improve their health. The configuration of the microcurrent therapy device is not limited to that shown in Figure 1, and various modifications are possible. For example, a smartphone or other device may be used as the main unit 10.

[0043] Next, I will explain the therapeutic effects of microcurrent therapy. Figure 2 is an explanatory diagram illustrating an example of the therapeutic effect of microcurrent therapy. Figure 2(a) shows the condition of SHR rats before the treatment experiment. The horizontal axis represents time, and the figure shows a specific cross-section of the heart. The white areas at the top and bottom represent the myocardium, and the black area between them represents the internal space of the heart. As shown in the figure, the heart is 7.65 mm in the expanded state and 2.57 mm in the contracted state, with a myocardial thickness of 4.52 mm, indicating a tendency toward myocardial hypertrophy and hypercontraction. Figure 2(b) shows the condition of SHR rats after treatment in which patches were applied to the back and belly and a weak electric current was delivered percutaneously to the heart. The weak electric current was delivered using the AT-Mini® low-frequency therapy device manufactured by Ito Chotampa Co., Ltd. This device can deliver a maximum current of approximately 340 μA in pulse patterns such as HEAL mode, CARE mode, and COMB mode. Figure 2(b) shows the condition after 6 weeks of weak electric current treatment. As shown in the diagram, the heart measures 8.84 mm when expanded and 5.54 mm when contracted, with a myocardial thickness of 4.15 mm, confirming that myocardial hypertrophy and hypercontraction have been alleviated.

[0044] Figure 3 is an explanatory diagram illustrating an example of the therapeutic effect of microcurrent therapy. It shows the results of an experiment using SHR rats similar to those in Figure 2. Cardiac output is shown for each of cases A to E. Case A is the state before treatment. Case B is the result after 3 weeks of electrical stimulation in care mode. Case C is the result after 6 weeks of electrical stimulation in care mode. In the case of electrical stimulation in care mode only, improvement was seen compared to before treatment, but no significant difference was observed between 3 weeks and 6 weeks. Case D shows the results after 3 weeks of electrical stimulation in combination mode. Case E shows the results after 6 weeks of electrical stimulation in combination mode. In both cases, improvement is observed compared to electrical stimulation in care mode only, and the improvement is even greater after 6 weeks than after 3 weeks.

[0045] The results shown in Figures 2 and 3 confirm that therapeutic effects can be obtained by applying a weak electric current. It was also confirmed that the effect is influenced by the pattern of the weak electric current and the duration of treatment. Therefore, the weak electric current therapy device of this embodiment makes it possible to treat organs or improve health by applying a weak electric current.

[0046] Figure 4 is a flowchart of the power supply control process. This process is executed by the control unit 20 of the main unit 10. When processing begins, the control unit 20 reads the target organ, the user's physical information, organ information, etc. (step S10). In specifying the target organ, the type of organ to be subjected to electrical stimulation is specified, such as the heart or liver. The user's physical information includes the user's gender, age, build, and other information directly or indirectly related to body composition. Organ information includes the location and size of the organs. This information may be read by operating the main unit 10, or it may be read from pre-stored data. It may also be read from a computer or the like.

[0047] Next, the main unit 10 determines whether the patch 1 being used is the appropriate patch (step S11), and if it is not appropriate, prompts the user to replace the patch (step S12). As already explained, it is desirable that the patch used for electrical stimulation covers at least 80% of the projected area of ​​the organ, so the appropriate patch is determined according to the organ. Therefore, if the patch is not appropriate, the user is prompted to replace it. Whether a patch is appropriate or not can be determined by various methods. For example, a barcode or similar identifier can be attached to the patch, and the main unit 10 can read it to recognize the patch and determine its appropriateness. Alternatively, a mechanism can be provided to recognize the type of patch by applying power to it.

[0048] If the correct patch is used (step S11), the control unit 20 measures the body fat percentage (step S13). A predetermined current is applied, and the body fat percentage is calculated according to the result.

[0049] Then, once the user's body composition, including body fat percentage, is obtained, the attenuation rate of the electrical current from the skin to the organs is calculated (step S14). The tissue conductivity of the human body is known for each tissue, including extracellular myocardium, intracellular myocardium, chest, internal tissue, skeletal muscle, lungs, arteries and veins, esophagus, stomach and intestines, spleen and liver, bone, and atrium. The control unit 20 stores these tissue conductivity values ​​and can estimate the thickness of each tissue in the pathway from the skin to the organs based on the user's body composition, and calculate the current attenuation rate. Alternatively, one could prepare a table or map containing pre-measured current attenuation rates from the skin to each organ, and then determine the attenuation rate by correcting this data according to body composition. Thus, the attenuation rate can be determined by various methods.

[0050] Once the attenuation rate is determined, the control unit 20 sets the target current and energization mode based on this (step S15). The value of the weak current to be flowed through the organs is set, and the current to be flowed through the skin is determined considering the attenuation rate. As for the value of the weak current, for example, in the case of the heart, 1 to 60 mA is preferred, and 30 to 60 mA is more preferred. Similar current values ​​are generally preferred for other organs as well. The mode of electrical stimulation refers to the pattern of the current frequency, waveform, etc. Multiple pre-configured patterns should be selected to achieve the desired therapeutic effect. The user may choose manually.

[0051] Thus, the control unit 20 starts supplying power (step S16). Then, it detects the impedance while power is supplied (step S17). The impedance can be determined by outputting a current of a predetermined frequency and detecting the actual current flowing in response.

[0052] If the current value exceeds a predetermined limit value Lim while power is supplied (step S18), the control unit 20 determines that power supply is dangerous, terminates the power supply, records the power supply result (step S21), and terminates the power supply control process. The limit value Lim may be a value that has been set in advance on the main unit 10 as a dangerous value, or it may be a value set as the limit value at which the user feels pain or discomfort. If patch 1 is equipped with a temperature sensor, in addition to the decision in step S18, or instead of step S18, the power supply may be terminated when the temperature detected by the temperature sensor exceeds a predetermined value. This allows for the detection of overheating in patch 1 during abnormal power supply and the termination of power supply, thereby improving safety. Furthermore, even if the instantaneous current value is within the normal range, there is the advantage that power supply can be terminated if the patch reaches a temperature that could affect the human body due to a long power supply duration.

[0053] If the current value is within the range of the limit value Lim (step S18), the control unit 20 repeatedly executes the processes from step S16 onward while adjusting the current value according to the impedance (step S20) until an instruction to terminate is given (step S19). Adjusting the current according to impedance is a type of feedback control to deliver a set target current. For example, when the impedance is high, it means the resistance is high, so the current value may be increased, and when the impedance is low, the current value may be decreased. Other control methods may also be employed. The end of power supply (step S19) can be indicated by the user using switch 13, or it can be set to automatically end after a predetermined period of power supply has been completed.

[0054] According to the microcurrent therapy device of the embodiment described above, by applying a weak electric current to an organ that does not affect its movement, it is possible to treat the organ or improve its health. Furthermore, since the weak electric current can be applied within a range that does not cause skeletal muscle contraction, pain or discomfort during use can be avoided.

[0055] The various features described in the examples do not necessarily need to be present in their entirety; some can be omitted or combined as appropriate. Furthermore, the present invention is not limited to the examples, and various modifications can be made. [Industrial applicability]
