Description

Electrical nerve treatment system and method using it

The present invention relates to an electrical nerve treatment system and a method using the same.

Electronic medicine is a compound word of electronics and pharmaceutical and refers to an electronic device that treats diseases by controlling electrical signals generated in the brain and nerve cells.

Today, electronic medicines are mainly used to improve disorders or problems that occur in nerves. The principle of electromedicine is the concept of improving or normalizing the pathophysiological environment by stimulating various cells, tissues, and organs, including nerves, with electrical signals generated artificially or through devices designed to be generated in response to body signals.

In the body, free ions, dipoles, and polarized molecules enable cells, tissues, and organs to generate and conduct electricity. Subtle bioelectricity regulates physiological phenomena and plays an important role in maintaining life. In the living body, homeostasis and harmony are controlled by electrical and chemical signals, and the electrical and chemical signals interact with each other. Changes in electrical signals can change chemical signals, and chemical signals can change electrical signals.

In the early days of electronic medicine development, simple implantable medical devices such as pacemakers were the mainstay. Recently, electronic devices that stimulate nervous tissue are evolving to treat chronic diseases such as epilepsy, diabetes, arthritis, and high blood pressure.

Traditional medicines used conventionally circulate through the blood vessels and have the potential to cause side effects in unwanted areas. On the other hand, electronic medicine is safe for the human body because it stimulates only the specific nerves that need treatment. Electronic medicine is used by being buried under the skin, so it can minimize side effects by stimulating only the specific area that needs treatment, and has the advantage of being able to immediately stop the drug's effectiveness in case of an emergency.

Figure 1 shows that electronic medicine is used to treat rheumatoid arthritis.

Rheumatoid arthritis, for which no treatment has yet been developed, is known to be a disease caused by an autoimmune reaction. Rheumatoid arthritis occurs when immune cells attack the joints and cause inflammation. In 2012, Dr. Kevin Tracy of the United States treated a patient with rheumatoid arthritis with electronic medicine. By inserting an electronic medicine into the patient's body and applying electrical signals to the nervous system that controls the spleen, the development of cells that control the immune system, such as T cells, was reduced.

Most of the currently developed electronic medicines use primary batteries. When the primary battery is completely discharged, it needs to be replaced with a new primary battery, so there is a problem that the battery is forced to be periodically taken out of the body.

As a prior art to solve this problem, Korean Patent No. 10-2284290, which is a registered patent by the present applicant, is disclosed. The prior art relates to 'electronic medicine for treating epilepsy capable of wireless charging and its control method'. The concept of electroweak capable of wireless charging is introduced, and a configuration that prevents electromagnetic interference generated by the wireless charger during the wireless charging process is disclosed. The composition of the prior art is significant in that it solves all the problems associated with using primary batteries at once.

Although secondary batteries can be repeatedly charged and discharged, they cannot be considered permanent.

Therefore, in order to maintain the permanent function of electromedicine, it is necessary to have a system that can properly collect bioenergy to enable true self-sufficiency of power, while also miniaturizing the size, and developing electromedicine that maintains stability is urgently needed.

Using the current information of the energy harvester module measured by the current sensing unit, when the current information is greater than a preset reference value; If at least one of the above applies, charging by the energy harvester module may be set to stop.

In addition, the control module includes a BMS unit connected to enable communication with the user terminal, and the BMS unit acquires charge/discharge information and remaining capacity information (State Of Charge, SOC) of the main power module and transmits it to the user terminal. It can be configured to do so.

In addition, the BMS unit detects the electrical connection status of the external wireless charging module and the main power module, and can provide the electrical connection status and real-time charging information to the user terminal.

Additionally, the BMS unit may provide an alarm to the user terminal to induce charging by the energy harvester module when the remaining capacity information of the main power module falls below a preset reference value.

In addition, the control module further includes a vibration sensor unit that detects vibration of the user's body, and when the vibration value sensed through the vibration sensor unit is greater than a preset reference value,

If the main power module is being charged by an external wireless charging module, the charging can be stopped and the main power module can be controlled to be charged by the energy harvester module.

Meanwhile, the present invention is a method of using the above-described electrical nerve treatment system, comprising the steps of: (a) applying a preset electrical stimulation from an electronic medicine to the user's nerves and performing a discharge mode of the main power module; (b) a step in which self-power generation is performed by applying vibration to the energy harvester module, in which a first charging mode for charging the main power module is performed; and (c) when the remaining capacity information of the main power module falls below a preset reference value, performing a second charging mode in which power is supplied wirelessly from an external wireless charging module; Provides a method including.

Electrical nerve treatment system equipped with energy harvester module

Below, with reference to FIGS. 2 to 7, the electrical nerve treatment system 100 will be described.

The electrical nerve treatment system 100 according to the present invention consists of an electromedicine 110, a main power module 120, an energy harvester module 130, and a control module 140. Since it is divided based on the function of the individual components, it can be physically composed into a single, integrated form.

In other words, the main power module 120 and the energy harvester module 130 of the present invention may be located not only inside the housing dividing the electroweak 110 but also outside the electroweak 110.

In this document, for convenience of understanding, the configurations are explained separately, and the control module 140 is explained separately in detail.

The electrical nerve treatment system 100 according to the present invention applies a secondary battery 122 capable of wireless charging and at the same time applies an energy harvester module 130 capable of real-time self-generation. That is, it is characterized by using the secondary battery 122 and the energy harvester module 130 in a hybrid method.

The electromedicine 110 is embedded under the skin and provides electrical stimulation to the nerves. For this purpose, a second channel line 101 is provided on one side of the electroweak 110. The electroweak 110 includes a housing that forms the exterior and an electrical stimulation generator 112. The second channel line 101 is configured to transmit the electrical signal generated by the electrical stimulation generator 112 to the nerve.

The electrical stimulation generator 112 may include a printed circuit board (PCB). In addition, since the PCB may be disturbed when charging by the wireless charging module 10, a structure and material that shields electromagnetic waves may be applied. The material may be at least one of metal such as non-toxic alumina ceramic (Al203) or titanium (Ti), non-toxic acrylic resin, synthetic resin such as nylon, Teflon, polyurethane, polyester, etc., and silicon.

The main power module 120 includes a secondary battery 122 and a wireless power receiver 124. As an example of the secondary battery 122, a capacity of 325 mAh (nominal 3.6 V) may be applied. Various types of secondary batteries can be applied. Depending on the designer's choice, the optimal shape can be applied, such as a cylindrical, square, or pouch-shaped battery.

As an example, a VNS (Vagus Nerve Stimulation) battery can consume 60 to 100 uWh of power in daily life. It is desirable that the secondary battery 122 be designed with a capacity that takes such power usage into consideration.

The main power module 120 includes a wireless power receiver 124. It is configured to receive power wirelessly from an external wireless charging module (10). At this time, the wireless charging module 10 may be used while connected to an external power source, but is not limited to this. If the wireless charging module 10 is an energy storage element, it can be configured to wirelessly supply the electric energy stored in the wireless charging module 10 without being connected to an external power source (plug).

Inside the electroweak 110 housing, the wireless power receiver 124 is preferably isolated from other elements by being provided inside a partition-shaped inner shield (not shown).

The energy harvester module 130 is configured to generate real-time self-generation using a friction element module. The energy harvester module 130 is a device inserted into the user's body, so when the user moves, a predetermined vibration (or external force) may be applied to the energy harvester module 130.

The principle of the energy harvester module 130 is as shown in FIG. 3.

The friction element module 132 may refer to the layer assembly form shown in FIG. 3. The friction element module 132 generates non-linear electrical energy using a friction element. This friction element may be a TENG (Triboelectric Nano-Generator).

The harvester unit 134 may be configured to sequentially store non-linear electrical energy generated through the friction element module 132 in a multi-stage energy storage (not shown) and supply the stored energy to the energy storage. At this time, the energy storage is a different structure from the battery and refers to an energy storage with a small energy storage space that is integrated with the electronic circuit.

Referring to FIG. 3, when different layers come into contact, the surface becomes charged due to frictional charging. The present invention can be performed through multiple layers. Below, for convenience of explanation, an example of double layered will be used, but this is a concept that can be applied to all multi-layers.

Specifically, when the two layers are separated, compensating charges are accumulated on the upper and lower electrodes due to electrostatic induction, and thus current flows through the external electrodes until the charge balance is achieved. When the two materials become closer again, the accumulated compensation charge disappears, causing a current in the opposite direction to the first to flow through the external electrode, and through repeated contact and separation processes, an alternating current continues to flow between the two electrodes. It is a principle.

The energy harvester module 130 is electrically connected to the main power module 120 and is configured to auxiliary charge the main power module 120. The secondary battery 122 of the main power module 120 may be charged in a hybrid manner by the wireless charging module 10 and the energy harvester module 130.

As an example, the energy harvester module 130 can be configured to generate 20uWh of energy (based on the harvester size of 100mm2), and is designed with a capacity to always compensate for 20 to 30% of the power consumption of the secondary battery 122. It can be. This means that it is designed to have a capacity of about 2% based on the capacity of the secondary battery 122.

The main power module 120 mainly receives power from the external wireless charging module 10, and the energy harvester module 130 serves to auxiliary charge the main power module 120. Although the power supply amount of the energy harvester module 130 is not a relatively large percentage, it is very effective in that it can continuously produce and supply electric energy in response to the user's movements.

Below, with reference to FIGS. 4 to 7, control of the main power module 120 and the energy harvester module 130 by the control module 140 will be described in detail.

The control module 140 controls charging of the main power module 120 and the energy harvester module 130.

The description will first be made with reference to FIG. 5 . Based on the main power module 120, the 'first charging mode' in which the main power module 120 receives power from the energy harvester module 130 and the main power module 120 receives power from the wireless charging module 10. It is classified into a ‘second charging mode’ that receives .

Here, it is preferable that the first and second charging modes are operated alternatively. That is, the main power module 120 may be configured not to be charged simultaneously by the energy harvester module 130 and the wireless charging module 10. Considering charging efficiency and capacity, charging by the wireless charging module 10 can generally receive more power, so the second charging mode can be set to take priority over the first charging mode.

The electrical stimulation generator 112 of the electroweak 110 may be in 'discharge mode' while generating an electrical stimulation signal. Discharge mode means that the electrical energy of the main power module 120 or the energy harvester module 130 is consumed.

Since it is efficient to configure the energy harvester module 130 to be capable of charging at all times, it is preferable to set it so that the discharge mode can be performed simultaneously when operating in the first charging mode. On the other hand, when operating the second charging mode, it is preferable to operate in a discharging stop mode, and when the second charging mode is terminated (meaning that wireless charging by the wireless charging module 10 is terminated), the discharge is automatically resumed. It can be set to run in mode.

This is to prevent electrical interference from occurring in the stable wireless charging and generation of the electrical stimulation signal from the electrical stimulation generator 112. This is because the second channel line 114 connected to the electrical stimulation generator 112 is directly connected to the nerves in the body, and even if minute electrical interference occurs, it may have a negative impact on the user.

However, the above charging mode operations may be designed to operate simultaneously depending on the designer's selection. That is, this means that even while the second charging mode is operated by the wireless charging module 10, the first charging mode can be operated simultaneously due to the user's movement. In this case, in order to maintain stable charging by the wireless charging module 10, a separate mounting means (or fixing means) may be used. The mounting means is configured in the form of a band having a predetermined elasticity, so that the wireless charging module 10 can be maintained in close contact with the body. Accordingly, even when there is movement of the user, the second charging mode can be performed continuously without interruption.

In other words, the present invention is a system that can safely and stably supply power even when the wireless charging module 10 and the energy harvester module 130 are connected together.

Detailed functions of the control module 140 will be described with reference to FIGS. 4 and 6.

The control module 140 includes a body temperature sensing unit 141, a battery temperature sensing unit 142, a current sensing unit 143, a BMS unit 144, and a vibration sensor unit 145. These are each configured to sense information subject to collection according to a preset cycle or condition.

That is, the user's body temperature information, temperature information of the main power module 120 (preferably the secondary battery 122), current information of the energy harvester module 130, and user's movement are quantified by the control module 140. It is configured to collect vibration information, which is one value. Each of these is configured to have a preset reference value, and when the collected value is greater than or equal to each reference value, the control module 140 instructs the energy harvester module 130 to stop charging. That is, the first charging mode is forcibly stopped.

If the above reference value is exceeded, there is a possibility of an error or malfunction of the energy harvester module 130, and the energy harvester module 130 is forced to stop to protect the user's body.

For example, if the body temperature information is higher than the standard value, there is a risk of damage to body tissue adjacent to the location where the energy harvester module 130 is installed. This is because it can cause deformation or destruction of body tissues made of protein. The temperature information of the main power module 120 and the current information of the energy harvester module 130 are also for the same reason.

The vibration sensor unit 145 is configured to detect vibration (or movement) of the user's body. This is linked to the user's physical activity. For example, when the user is sleeping, the vibration may be relatively low, but when the user is active outdoors, the vibration may be relatively high, and power generation by the energy harvester module 130 may be actively performed.

If the user is charging through the wireless charging module 10 and the vibration value is higher than the reference value, the user may be instructed to stop operating the second charging mode by the wireless charging module 10. This notification may be provided through the user terminal 20.

The wireless charging module 10 can be charged while wearing a separate body restraint device for stable charging (second charging mode), and even when the second charging mode is being performed, the user can exercise actively. can do.

Meanwhile, the control module 140 may include a BMS unit 144. The BMS unit 144 may be provided in each of the main power module 120 and the energy harvester module 130, but herein, for convenience of explanation, it is defined that the BMS unit 144 is included in the control module 140. did.

The BMS unit 144 monitors the status of the main power module 120 and the energy harvester module 130. In particular, it is configured to obtain charge/discharge information and remaining capacity information (State Of Charge, SOC) of the main power module 120 and transmit them to the user terminal 20.

Through the user terminal 20, the user can check the current status of the main power module 120, predict when wireless charging is needed, the remaining use time of the electronic medicine 110, etc.

Additionally, the BMS unit 144 may be configured to detect the electrical connection status of the external wireless charging module 10 and the main power module 120 and provide the electrical connection status and real-time charging information to the user terminal. This is because, due to the nature of wireless charging, it is necessary to position the wireless power supply unit (not shown) of the wireless charging module 10 and the wireless power receiving unit 124 of the main power module 120 to correspond to each other.

If they are not in place, it is necessary to notify the user and force the user to place them in place.

Additionally, the BMS unit 144 may induce charging by the energy harvester module 130 when the remaining capacity information of the main power module 120 falls below a reference value. When it is difficult to use the wireless charging module 10, charging by the energy harvester module 130 is induced by inducing the user's movement. Since the electrical nerve treatment system according to the present invention uses the main power module 120 and the energy harvester module 130 in a hybrid method, the above alarm can be very useful.

With reference to Figure 7, a method using the electrical nerve treatment system according to the present invention will be described. Descriptions that overlap with the above are omitted.

This method may consist of steps S110 to S130.

Step (S110) is a step in which the discharge mode of the main power module 120 is performed while a preset electrical stimulation from the electroweak 110 is applied to the user's nerves.

Step S120 is a step in which self-power generation is performed by applying vibration to the energy harvester module 130, and is a step in which a first charging mode for charging the main power module 120 is performed. As the user goes about his or her daily life, vibration is naturally applied to the friction element module 132, thereby producing non-linear electrical energy.

Of course, the first charging mode can be performed simultaneously with the discharging mode in step S110.

In step S130, when the remaining capacity information of the main power module 120 falls below a preset reference value, a second charging mode in which power is supplied wirelessly from an external wireless charging module is performed. Here, when the second charging mode is performed, it may be operated in a discharge stop mode in which power supply from the main power module 120 to the electroweak is stopped.

Energy harvester module connected to the outside of the electrochemical device

Below, with reference to FIGS. 8 to 15, the energy harvester module according to the present invention will be described. The energy harvester module 130 described below may be divided into different embodiments of the electrical nerve treatment system described above. The above-described embodiment was described on the premise that the energy harvester module 200 is located together in the electroweak 110 housing. However, in another embodiment described below, the energy harvester module 230 is located outside the electroweak 210. It is a structure that is located independently.

Redundant descriptions of the individual components described above will be omitted.

Referring to FIG. 8, the energy harvester module 230 may be distinguished from the above-described first embodiment in that it is located outside the electroweak 210. That is, when the lifespan of the energy harvester module 230 expires or replacement is required, only the energy harvester module 230 can be replaced and used separately from the electroweak 210.

For reference, a control module 240 and a main power module 220 are provided inside the electroweak 210 housing.

The energy harvester module 230 includes a generator 233, a harvester unit 235, and a case 231.

The case 231 forms the exterior of the energy harvester module 230 and protects the internal components. In order to protect the interior from strong external forces, it is preferably made of titanium. A feed-through 236 is formed on one side of the case 231, and a first channel line 237 is formed to extend in the direction of the electroweak 210 through the feed-through 236.

The generator 233 generates non-linear electrical energy using the friction element module 232. The principle of generating electric energy using the internal friction element module 232 is as explained in FIG. 3.

The friction element module 232 may be any known element capable of generating triboelectricity. Examples of devices applicable to the present invention are as follows. This is a simple example, and is not limited thereto.

1) Integrated system for energy conversion and storage through flexible triboelectricity, nanogenerator and supercapacitor based on ZnO nanorods@conductive carbon black nanocomposite;

2) Co/Zn bimetallic organic framework elliptical nanosheets in flexible conductive fabrics for energy harvesting and environmental monitoring through triboelectricity;

3) High-performance triboelectric nanogenerator based on double-layered electrode effect;

4) Hybrid nanogenerator (sliding) by combining triboelectricity and thermoelectricity, through frictional heat for advanced smart sensors;

The harvester unit 235 is configured to temporarily store electrical energy provided from the generator 233 in a preset manner. The non-linear electric energy generated through the friction element module 232 of the generator 233 is sequentially stored in the multi-stage multi-energy storage (235a, 235b, 235c), and the energy stored in the multi-energy storage (235a, 235b, 235c) Provides energy. At this time, the multi-energy storage 220 is a different configuration from a battery (or battery) and refers to an energy storage with a small energy storage space integrated with an electronic circuit. The harvester unit 235 shown in FIG. 9 is an exemplary structure, and the number of multiple energy storages 235a, 235b, and 235c can be optimally designed according to the designer's selection.

The harvester unit 235 is connected to the first channel line 237, and can provide real-time electrical energy to the electroweak 210 through the first channel line 237.

Referring to FIG. 10, the electromagnetic drug 210 is provided with a second channel line 202 that contacts the target nerve (illustratively referred to as the 'vagus nerve' in FIG. 3). Electrical energy provided from the energy harvester module 230 may be provided to the nerves in the user's body through the secondary battery 222 and the second channel line 202.

The first channel line 237 may be connected through the connector portion 226. Based on the connector portion 226, the part connected to the electroweak 210 is called a first channel line A (237a), and the part connected to the energy harvester module 230 is called a first channel line B (237b). .

The first channel line A (237a) and the first channel line B (237b) are connected to each other through the connector portion 226. In this way, by providing the connector portion 226, the energy harvester module 230 can be easily replaced.

Figure 10 shows a modified example of the energy harvester module 230. It shows a configuration in which electrical energy is not only supplied through the first channel line A (237a) and first channel line B (237b), but also a wireless charging method is possible.

For this purpose, the energy harvester module 230 may be provided with a wireless power transmission unit 238, and the electroweak 210 may be provided with a wireless power reception unit 224. Here, the wireless power receiver 224 on the electroweak 210 side is preferably used in conjunction with the external wireless charging module 10. Unlike charging using the wireless charging module 10, wireless charging using the energy harvester module 230 is distinguished in that it is constant charging. Of course, charging conditions, methods, and cycles can be set according to the administrator's selection.

The secondary battery 222 of the electroweak 210 may be connected to the capacitor unit 226. The capacitor unit 226 may not have a relatively large charging capacity compared to the secondary battery 222. Even though the capacitor unit 226 does not have a very large charge capacity, it can be stably used inside a living body without any structural change because it physically absorbs electrons. In addition, since electrons can be emitted in a very fast time and can be applied to high output, it can be used very effectively as an alternative or auxiliary power source for the electroweak 210.

Figure 11 schematically shows a generator 233 equipped with an amplification damper 233c.

The amplifying damper 233c is coupled to a pre-calculated position and is formed to sustain the fine movement of the friction element, taking into account the user's movement. As shown in FIG. 11, it can be formed on the outermost layer of the friction element module, and can be formed in plural numbers, with sizes corresponding to regular intervals.

People usually engage in activities through various movements, and due to these movements in daily life, the generator 233 to which the amplification damper 233c is attached generates power, and even during movement or at the moment when movement is stopped. The amplification damper 233c can maximize power generation characteristics by continuing the fine movement of the friction element within the spaced apart space.

As shown in FIG. 11, the generator 233 may be composed of multiple layers. This will be explained using the double layer, the most basic of multi-layers, as an example.

The multi-layer double layer of FIG. 11 is divided into a first layer 233a and a second layer 233b. Electrical energy is generated by friction when the first and second layers 233a and 233b come into contact.

Referring to Figure 12, it shows the arrangement of the generator considering the user's movement. The form shown in FIG. 12 takes into account the user's lifestyle pattern, and for people who frequently walk, it is desirable to provide a generator arrangement optimized for walking motion.

That is, by matching the direction in which the external force is mainly applied (meaning the direction of force) and the arrangement direction of the multi-layers 233a and 233b in the generator 233, the applied external force causes friction of the multi-layers 233a and 233b. Encourage it to be used as much as possible.

This inclination angle (θ) can be calculated based on the user's stride length. This is because in a situation where the user is walking, the user's stride length affects the inclination of the user's body. Since each user's physical condition is different and the stride length is also different, the administrator can set the inclination angle (θ) optimized for the user.

Additionally, the area of the multi-layer may be determined by considering the frequency and time of the user's movement. For users who move a lot, the desired charging capacity can be secured even if the area of the multi-layer is relatively small. For users with little movement, the friction area can be increased by forming a large area of the multi-layer. The area of the multi-layer can be achieved by adjusting the length (l) and width (d).

It is desirable that the inclination angle (θ) and the area of the layer are set to values optimized for the user by securing data on the user's walking characteristics and behavioral characteristics through a smart watch, etc.

Figure 13 is a schematic diagram of an electrical nerve treatment system to which the energy harvester module of the present invention is applied. It matches the conceptual diagram shown in FIG. 3.

The electroweak 210 is formed so that two channel lines are combined. It consists of a first channel line 237 connected to the energy harvester module 230, and a second channel line 202 connected to the nerve. The tip 202a of the second channel line 202 contacts the nerve area.

The form shown in FIG. 13 shows an exemplary form of the electroweak 210 as well as the energy harvester module 230 according to the present invention, and may be designed in different shapes and sizes. The shape of the energy harvester module 230 may also be circular with respect to a plane.

With reference to FIG. 14, a modified example of the multi-layer 230' will be described. The modified example shown in FIG. 14 is a structure in which directionality is given to the sides that face each other (meaning the sides that rub against each other). A plurality of unit friction elements 239a and 239b are formed on the facing surfaces, respectively.

Unit friction elements 239a and 239b formed on each of the upper first layer 233a and second layer 233b have shapes corresponding to each other. The unit friction elements 239a and 239b are formed to have a predetermined slope. This can be viewed as the same concept as the inclination angle (θ) described above. Considering the angle of the user's body, the inclination angle of the unit friction elements 239a and 239b is designed. The length (a), number, position, and spacing of the unit friction elements 239a and 239b can be configured in a form optimized for the user according to the designer's selection.

Here, the remaining distance (b) between the multi-layer 230' and the case 231 takes into account the hypotenuse length of the unit friction elements 239a and 239b. In other words, it is desirable that the remaining distance (b) is sufficiently formed to not interfere with sliding.

Electronic drug monitoring system

*In the following, the electroweak monitoring system 300 according to the present invention will be described with reference to FIGS. 16 to 22. Redundant description of the detailed configurations described above will be omitted.

The electroweak monitoring system 300 consists of an electroweak 310, a main power module 320, an energy harvester module 330, and a control module 340.

The control module 340 checks the status and controls the operation of the electroweak 310, the main power module 320, and the energy harvester module 330. In addition, a communication unit 341 capable of wireless communication with the user terminal 20 is provided. The communication unit 341 is wirelessly/wiredly connected to the network and is configured to transmit the obtained information to the user terminal 20.

In relation to wireless communication of the present invention, the present invention includes Personal Communication System (PCS), Global System for Mobile communications (GSM), Personal Digital Cellular (PDC), Personal Handyphone System (PHS), Personal Digital Assistant (PDA), and IMT ( International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal, smartphone, smartpad, tablet All types of handheld-based wireless communication devices such as PCs (Tablet PCs) and computing devices such as stationary PCs and laptops can be used, and the above distributed applications are implemented in the form of computer programs and can be read and written. It can be recorded on a possible recording medium and mounted on the terminal.

Additionally, the system according to the present invention is based on a network, and the network refers to a connection structure that allows information exchange between nodes such as terminals and servers. Examples of such networks include the 3rd Generation Partnership Project (3GPP) network, Long Term Evolution (LTE) network, World Interoperability for Microwave Access (WIMAX) network, Internet, Local Area Network (LAN), and Wireless LAN. (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), Bluetooth network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, WiFi, etc. It is not limited.

Referring to FIG. 16, the present invention is characterized by transmitting information obtained through the control module 340 to the user terminal 20. The communication unit 341 may be composed of a transceiver capable of two-way communication.

Referring to FIG. 17, the secondary battery 322 of the main power module 320 may be configured to receive power by being connected to the auxiliary power supply unit 324. The auxiliary power unit 324 includes a capacitor. As a modified example, the auxiliary power unit 324 may be connected to the communication unit 341. At this time, the communication unit 341 may be configured with a commercial Bluetooth Low Energy (BLE) board to perform short-distance communication with the user terminal 20.

With reference to FIG. 18, the control module 340 of the present invention will be described.

The control module 340 includes a first status management unit 342, a second status management unit 343, a normal operation determination unit 344, and a wireless charging operation unit 345, which are all connected to the communication unit 341 and interact with each other. It is designed to exchange information.

The first state management unit 342 manages the state of the main power module 320 and is configured to obtain and store charge/discharge information and remaining capacity information (State Of Charge, SOC) of the main power module 320. The state of the main power module 320 is a broad concept meaning all states of the secondary battery 322 included in the main power module 320.

As an example, the first state management unit 342 may control the main power module 320 to receive power from the auxiliary power unit 324 when the sensed remaining capacity information is below a preset reference value. To this end, it is desirable to design the remaining capacity information of the auxiliary power unit 324 so that it can also be checked in real time by the first status management unit 342.

The second status management unit 343 manages the status of the energy harvester module 330 and is configured to obtain and store power information generated by the energy harvester module 330. The energy harvester module 330 performs self-power generation by the user's movement, and the self-power generation performance history is automatically saved. Conversely, the user's movement can be reversely estimated through the second state management unit 343.

The normal operation determination unit 344 determines the normal operation of the main power module 320 and the energy harvester module 330. Information about the normal operation of the main power module 320 and the energy harvester module 330 is predefined in the control module 340.

The present invention includes an electromagnetic drug that applies electrical signals to the user's nerves, and determining normal operation is a very important function to protect the user's body and prevent accidents.

As an example of determining normal operation, the communication unit 341 and the user terminal 20 are connected in a preset manner using the remaining capacity information of the main power module 320 and the generated power information of the energy harvester module 330. There is a way to determine normal operation by calculating the maximum operating time of wireless communication.

Even though the remaining capacity information of the main power module 320 and the generated power information of the energy harvester module 330 are sufficient, the maximum wireless communication operation time between the communication unit 341 and the user terminal 20 is calculated to be a significantly low value. If this happens, it can be judged as ‘abnormal’. This may mean that a lot of power is consumed in other elements other than the main power module 320 and the energy harvester module 330, or it may be a wireless communication error that makes it impossible to transmit and receive accurate information.

It is important to immediately resolve these issues, but it is also very important to quickly provide users with information on whether the device is operating normally. In the case of 'abnormality', the user is forced to immediately stop the operation of the electronic medicine 310.

The control module 340 further includes a wireless charging operation unit 345 that calculates the wireless charging timing of the main power module 320 and provides the wireless charging time to the user terminal 20.

The remaining capacity information of the electronic drug 310 of the present invention is the most important information for protecting the user's body. This is because it is directly related to the normal operation of the electronic drug 310.

19, the wireless charging operation unit 345 receives corresponding information from the main power module 320 and the energy harvester module 330, respectively. It is desirable to receive real-time information, but certain cycles and conditions can be set.

The wireless charging time of the main power module 320 is determined using the power consumption of the main power module 320, the remaining capacity information of the main power module 320, and the generated power information of the energy harvester module 330.

19 shows an example method.

The wireless charging operation unit 345 calculates the ‘first expected use time’ based on the current remaining capacity information of the main power module 320. Afterwards, based on the 'first expected available time', the expected generated power information of the energy harvester module 330 is calculated, and the second expected available time is determined based on this.

If the secondary expected available time is less than a predetermined value, a re-determination is performed as to whether power saving mode is necessary. It is desirable that the power saving mode is set by the user's selection. This is because it is important for the user to recognize that power saving mode is currently in effect.

To this end, the first and second state management units 342 and 343 may be configured to store all acquired information in conjunction with time information.

At this time, the wireless charging operation unit 345 calculates the power consumption amount used for the electrical stimulation applied from the electromagnetic drug 310 and the power information generated by the energy harvester module 330 according to the user's movement based on time in a preset manner. By analyzing, it is possible to determine the wireless charging time of the main power module 320.

In other words, this means determining the wireless charging time of the main power module 320 based on past usage history. Based on 24 hours per day, predictions are made based on statistics on power consumption and generated power information used for electrical stimulation at a specific time. Forecasting methods may use statistical techniques such as regression analysis.

Referring to FIG. 20, you can see detailed information collected from the control module 410 of the present invention. These detailed information are configured to be confirmed on the user terminal 20. If the user terminal 20 is a smartphone/smart tablet, it can be checked through an installed application.

The control module 410 includes a body temperature sensing unit 340a, a battery temperature sensing unit 340b, a current sensing unit 340c, a tissue temperature sensing unit 340d, a blood flow sensing unit 340e, and a feedback signal sensing unit 340f. The information is provided from .

Specifically, the user's body temperature information measured by the body temperature sensing unit 340a, the temperature information of the main power module 320 measured by the battery temperature sensing unit 340b, and the energy measured by the current sensing unit 340c. Current information of the harvester module 330, temperature information of adjacent tissues where the electromedicine 310 is installed measured by the tissue temperature sensing unit 340d, and electromedicine 310 installed measured by the blood flow sensing unit 330e. It is configured to provide blood flow information of adjacent blood vessels to the user terminal 20.

Additionally, the control module 340 may be configured to analyze a feedback signal for the electrical signal applied to the electrical stimulation generator 312. Through analysis of these feedback signals, it is possible to check not only whether the nerve is damaged, but also the transmission status of the electrical signal.

As a modified example of the present invention, the control module 340 may further include an electrical stimulation setting unit 347. The electrical stimulation setting unit 347 is a component related to electronic prescriptions at medical institutions.

The electrical signal of the electroweak 310 may be composed of various elements such as intensity, pattern, and type. This can be named a ‘dataset’. These datasets can only be set up by administrators (experts) with prescribing authority. This is because the act of treating using electronic medicine 310 can be included within the scope of medical practice.

Medical treatment and electronic prescriptions can be performed remotely through the user terminal 20. When the user receives a new electronic prescription from the administrator, the operation content including the intensity, cycle, and pattern of the electrical stimulation is updated in response to the electronic prescription. That is, a new data set is created, and the electrical stimulation generator 312 is configured to apply an electrical signal according to the contents of the new data set.

Referring to FIG. 22, the present invention provides a configuration for communicating through a user terminal 20 and a server. As described above, it can be performed through an application installed on the user terminal 20.

Specifically, when a login request is received from the user terminal 20, a user interface is provided for each of the main power module 320, the energy harvester module 330, and the electronic drug 310. Users can select any one of these and can check status information for the selected item in real time.

First, when the user interface for the main power module 320 is selected by the user, charge/discharge information and current remaining capacity information of the main power module 320 obtained from the first status management unit 342 are provided.

When the user interface for the energy harvester module 330 is selected by the user, the generated power information and power generation efficiency information of the energy harvester module 330 obtained from the second state management unit 343 are provided.

When the user interface for the electromedicine 310 is selected by the user, the electrical stimulation information obtained from the third state management unit 344 is provided in chronological order, and a feedback signal of the electrical stimulation applied to the nerve is provided. In other words, it means providing history information about electrical stimulation.

In the present invention, the above embodiment is an example and the present invention is not limited thereto. Anything that has substantially the same structure and achieves the same effect as the technical idea described in the claims of the present invention is included in the technical scope of the present invention.
