Description

Technical Field

[0001] The present invention relates to a smart band-aid that allows an individual to use wired or wireless power from a personal or portable terminal to treat trauma and wounds without going to a hospital, and a smart band-aid control system containing the same, which accelerates wound healing by applying electrical stimulation to the wound site, applies the best wound treatment method according to the wound, and has the function of protecting the wound site from external influences. Background Art

[0002] Using electrical stimulation to treat wounds. Fine electrical stimulation accelerates the healing ability of wounds by accelerating the proliferation and differentiation of fibroblasts.

[0003] The problem with current treatments using electrical stimulation is that when wounds are treated by electrical stimulation to rapidly heal wounds, the external resistance of various infiltrate chemicals generated in the wound or the size and deviation of bioresistance based on fibrin are different, and since the infiltrate chemicals must be constantly absorbed and replaced, it is difficult to obtain a significant effect.

[0004] Therefore, the method of directly stimulating the inside of the wound area through electrodes is the most effective, but the method of directly electrically stimulating the inside of the wound requires surgery or a separate wearable or fixed device, thereby reducing the convenience and cost effectiveness of wound treatment for patients. Therefore, in wound treatment, miniaturized products and control solutions are needed that can effectively restore the wound while applying electrical stimulation directly to the inside of the wound.

[0020] Also, the electrode pattern may include molybdenum.

[0021] Furthermore, the molybdenum is composed of a thin film with a thickness of 0.1 μm to 10 μm, and a cross-sectional area is less than 10% of the target site.

[0022] Furthermore, it also includes a molybdenum detection unit, which is arranged in the communication module and is used to detect the molybdenum in the target area. The processor can be configured to control the communication module and the electrode module to form the electric field for removing the molybdenum in the target area when it is determined that the impregnant is in an unsaturated state.

[0023] Furthermore, the device further includes a triboelectric power generation device which is provided in the communication module and supplies triboelectricity generated by friction due to ultrasonic irradiation as electric power to the communication module.

[0025] Furthermore, when removing the smart bandage, the electrode bandage module and the communication module can be separated from the target part together, or only the communication module can be separated from the target part, and then the electrode module can be separated after being completely melted by the user's biological heat.

[0026] Furthermore, the nano-liposome may contain lipase.

[0061] Hereinafter, a smart bandage for treating trauma and wounds and a smart bandage control system including the same according to an embodiment of the present invention will be described.

[0062] Figure 1aThis is a three-dimensional diagram showing a self-healing intelligent bandage control system for treating trauma and wounds according to an embodiment of the present invention. Figure 1b This is a schematic diagram showing an example of using a self-healing smart bandage control system for treating trauma and wounds according to an embodiment of the present invention. Figure 1c It is a schematic diagram showing the bioimpedance according to electrical stimulation of a control system of a self-treatable smart bandage for treating trauma and wounds according to an embodiment of the present invention.

[0063] like Figure 1a to Figure 1b As shown, a smart band-aid control system for treating trauma and wounds according to an embodiment of the present invention includes an electronic device 100 and a smart band-aid 200 for treating trauma and wounds.

[0064] refer to Figure 1a to Figure 1b According to an embodiment of the present invention, the smart bandage control system is composed of an electronic device 100 and a smart bandage 200 for treating trauma and wounds. The smart bandage 200 for treating trauma and wounds can be connected to the electronic device 100 for communication.

[0065] The electronic device 100 includes all types of electronic devices that provide short-range communication (e.g., NFC, etc.) and wireless power transmission functions. For example, the electronic device 100 is a device that can provide power to, control, and communicate with the smart bandage via wired or wireless communication, including but not limited to smart phones, tablet computers, smart watches, smart bracelets, etc.

[0066] The electronic device 100 can not only use a wireless or wired communication device to power the smart bandage 200, but also collect the wound status of the user in the smart bandage 200 for wound and wound treatment and send the information to the individual, doctor or place where medical information, diagnosis and prescription are collected. Thus, the electronic device 100 receives information from a remote location or a nearby location through the application or program of the electronic device 100 itself, and controls the smart bandage 200 for wound and wound treatment based on the information. In addition, the electronic device 100 can send relevant information to a remote location or a nearby location through a linkage device such as a nearby IOT.

[0067] Furthermore, the electronic device 100 can provide the user with "usage information" or "product installation method" of the smart bandage 200 for wound and injury treatment, send the user's wound information to the hospital, and reflect the prescription information issued by the hospital, so as to control the electrical stimulation applied by the smart bandage 200 for wound and injury treatment to the user's wound to increase the treatment effect of the user's wound (see Figure 1b ).

[0068] The electronic device 100 can provide the user with control information and charging information of the smart bandage 200 for trauma and wound treatment. In addition, the electronic device 100 can use the user's actions to obtain information such as usage status, treatment status, product number, product installation method and usage time, and provide this information to the hospital through the smart terminal used by the user. Therefore, the electronic device 100 does not simply self-treat the user's wound, but reflects the real-time diagnosis provided by the hospital and the prescription results issued by the hospital based on the user's wound treatment situation, thereby providing the user with various information such as the user's wound treatment, the user's appointment for medical treatment and the replacement cycle of the smart bandage (see Figure 1b ).

[0069] The smart bandage 200 for wound and wound treatment may receive power from the electronic device 100. Also, the smart bandage 200 for wound and wound treatment is attached to the target part 10 of the user to evaporate the impregnation of the target part 10 of the user and apply electrical stimulation to the wound in the target part 10 of the user.

[0070] Generally speaking, when a wound in a living body heals, nerves and cells try to repair the original wound based on an electrical phenomenon called action current, and the main role is played by granulation tissue with fibroblasts, which plays a role in restoring tissue by synthesizing tissue components such as collagen in cells. In this case, fine electrical stimulation can accelerate tissue repair by accelerating the proliferation and differentiation ability of fibroblasts.

[0071] Among them, the problem is that when wound healing is accelerated by external stimulation (such as electrical stimulation), it is difficult to obtain a significant effect due to the uneven external resistance of various chemical substances generated in the wound or the size / deviation of the bioresistance according to fibrin. Therefore, although the method of directly stimulating the inside of the wound by electrodes is the most effective, its effectiveness is reduced because direct electrical stimulation of the inside of the wound with electrodes requires more portable surgical equipment and instruments. In response to this problem, a negative pressure device based on a wound dressing is currently being used to treat the wound by discharging exudate to reduce the deviation of bioresistance and unblocking blood flow to reduce bioresistance and promote blood flow. In addition to the characteristics of protecting and disinfecting the wound by creating a moist environment, it is close to natural treatment and is not as efficient as the electrical stimulation method. Therefore, the applicant continues to study how to use conductive biomaterials to accelerate the recovery of the dermis with electricity as a method to minimize wound stimulation due to external resistance to chemical substances without surgery, and has developed a smart bandage 200 for wound and wound treatment according to an embodiment of the present invention.

[0072] The smart bandage 200 for wound and wound treatment according to an embodiment of the present invention may include transient materials, wherein the transient materials may temporarily operate to apply electrical stimulation to the wound site and may be absorbed into the living body during the wound healing process.

[0073] As an example, if the smart bandage 200 for wound and injury treatment is attached to the user's target part 10, part of the transient material contained in the smart bandage 200 for wound and injury treatment is inserted into the user's target part 10 to apply electrical stimulation to the inside of the wound at the user's target part.

[0074] As an example, the transient material may be at least one of nano-molybdenum (Mo), molybdenum disulfide (MoS2), tungsten disulfide (WS2), zinc oxide (ZnO) and magnesium oxide (MgO), but the present invention is not limited thereto. The transient material is a conductive material that is harmless to the human body. When the transient material provides electricity to the wound site and applies electrical stimulation, fibroblasts rapidly proliferate and differentiate, allowing the dermis to recover quickly, and the wound site heals through this process.

[0075] However, although this method accelerates dermal recovery through electrical stimulation, there are the following problems: the recovery tension drops to 80% of the level before the wound, it is impossible to get rid of the existing wound scab (a scab formed when blood, pus, exudate, etc. dry), and the wound exudate evaporates quickly (Evaporation). In other words, the exudate contains macrophages that can remove foreign matter such as dead cells and bacteria, white blood cells and lysosomal enzymes that promote wound healing, and growth factors. When these components evaporate due to electrical stimulation, the recovery of the wound will slow down.

[0076] In particular, electrical stimulation is electrical stimulation using microcurrent and voltage, and bioresistance (R) varies depending on the extent and size of the user's wound and the degree of healing, so even if the same microcurrent and voltage are supplied to the wound, it may have the same characteristics as a variable resistor (see Figure 1c ). For example, when the user's wound size is large, the bioresistance (R) is relatively low and the R value is low, but when the treatment is completed, the bioskin resistance (R) value is 2.5~10MΩ. In particular, the extremities (such as the feet) have a higher bioresistance (R), while the upper body (such as the chest) has a lower bioresistance. The initial internal resistance of the area with a larger wound area will decrease to a maximum of 300 to 750Ω, and the internal resistance may increase depending on the distance from the heart.

[0077] According to an embodiment of the present invention, the smart bandage 200 for trauma and wound treatment provides electrical stimulation inside the wound through wound insertion material to restore the dermis, while creating a moist environment without evaporating exudate, etc., thereby providing an experience of improving the wound's recovery ability and wound healing speed.

[0078] Hereinafter, a self-treatable smart bandage 200 for treating trauma and wounds according to an embodiment of the present invention will be described in detail.

[0079] Figure 2 This is a three-dimensional diagram showing a self-healing smart bandage for treating trauma and wounds according to an embodiment of the present invention. Figure 3 To show the structural block diagram of a self-healing smart bandage for treating trauma and wounds according to an embodiment of the present invention, Figure 4 The present invention is a block diagram showing the structure of a communication module of a smart band-aid for self-healing trauma and wound treatment according to an embodiment of the present invention.

[0080] like Figures 2 to 4 As shown, the smart bandage 200 for trauma and wound treatment according to an embodiment of the present invention can be divided into an electrode bandage 290 directly attached to the wound and an auxiliary component 300 surrounding the smart module 280, and includes an electrode bandage module 210, a communication module 220, an electrode module 230 and a processor 240, a temperature sensor 227, a communication module electrode 228 and a detection unit electrode 229.

[0081] In the present invention, the target site 10 of the user may be a part of the user's body including a wound of the user.

[0082] The electrode bandage module 210 plays the role of attaching the electrode module 230 to the target part 10 of the user. To this end, an auxiliary component 300 for attaching the target part 10 of the user can be set on one side of the electrode bandage module 210. For example, the auxiliary component 300 can be a polyurethane film, but the present invention is not limited to this. As an example, the polyurethane film includes a porous polyethylene that is moisture-permeable and moisturizing, which can penetrate water vapor and air for heat exchange and prevent external pathogens (such as bacteria) and water droplets. As another example, the thickness of the polyurethane film is 10 to 100 μm. At this time, the polyurethane film that can be used as the auxiliary component 300 can be used to exchange and remove the smart bandage. Specifically, when the electrode bandage module 210 is completely fused to the wound, or the electrode module 230 is fused to the wound, the polyurethane film can be used to remove it. In particular, since the electrode bandage module 210 plays the role of maintaining the main humidity, during the wound treatment process, only the nano-liposome 231 and the electrode module 230 are sucked into the user, and the electrode bandage module 210 is separated and not melted. There are many cases. However, since the electrode bandage module 210 is made of a hydrocolloid substance, it can provide a cool feeling while forming a colloidal gel to reduce the temperature.

[0083] The communication module 220 is connected to the electrode wound patch module 210 and has a wireless power transmission function, wherein the wireless power transmission function can be that the communication module 220 provides power to the electrode module 230 described later.

[0084] As an example, the communication module 220 supplies the power supplied from the electronic device 100 to the electrode module 230. At this time, the communication module 220 receives the power from the electronic device 100 through the NFC function.

[0085] As another example, the communication module 220 supplies the electric power supplied from the friction electric power generating device 270 described later to the electrode module 230 .

[0086] The communication module 220 includes one or more circuit devices to realize the communication function and the wireless power transmission function. Such a communication module 220 can be realized by using NFC technology. In addition, the communication module 220 adjusts the time of supplying power to the electrode module 230 according to the control of the electronic device 100 or the processor 240. In this way, by adjusting the time when the communication module 220 supplies power to the electrode module 230, the time when the electrode module 230 forms an electric field to apply electrical stimulation to the user's target part 10 and evaporate the impregnation of the target part 10 is adjusted. For example, the communication module 220 is implemented by an active RFID that supports wireless power transmission and communication. Alternatively, the communication module 220 can also use various standard wireless communication technologies such as Bluetooth modules and Wi-Fi modules, and can also use various standard wireless power transmission technologies such as Qi, AirFuel, WiTricity, PMA (Power Matters Allicance), etc.

[0087] The communication module 220 includes an antenna 221, an NFC integrated circuit 222, a microcontroller unit MCU 223, a first LDO regulator 224, a second LDO regulator 225, a third LDO regulator 226, a temperature sensor 227, a communication module electrode 228 and a detection unit electrode 229 (see Figure 4 ).

[0088] The antenna 221 has the function of receiving radio waves from the electronic device 100 in a wireless manner. The antenna 221 is capable of receiving a signal of 13.56 MHz, which is a standard frequency of NFC, and can be manufactured in the form of a flexible printed circuit board (FPCB). The antenna 221 uses energy provided by an electric field or a magnetic field to induce power. For example, the antenna 221 receives a voltage of 1.4 V to 6 V and a current of up to 300 mA based on the power supplied from the electronic device 100.

[0089] The NFC integrated circuit 222 can supply power required for the operation of the micro control unit MCU 223 and power required for the operation of the first LDO regulator 224 , the second LDO regulator 225 , and the third LDO regulator 226 .

[0090] The microcontroller unit MCU 223 judges the resistance based on the value input to the ADC, determines whether to use one of the first LDO regulator 224 to the third LDO regulator 226 based on the value controlled in the smartphone, and provides the power required for the operation of the regulator determined to be used. To this end, the microcontroller unit MCU 223 receives temperature information of the wound site from the temperature sensor 227, and the detection electrode 229 sends the feedback value of the electrical stimulation value generated by the wound to one of the first LDO regulator 224 to the third LDO regulator 226 to the ADC of the microcontroller unit MCU 223, and compares it with the output voltage and current of the LDO, so that the resistance size can be inferred only by the change in voltage. The degree of wound treatment is inferred by the resistance value of the wound, and the initial wound treatment value (degree) is determined by Figure 2 The diagnostic results shown are defined by remote input and are not user defined.

[0091] The communication module electrode 228 is connected to the electrode pattern 232 of the transient material. The communication module electrode 228 is made of a non-transient metal with high electrical conductivity and can be removed together with the communication module 220 .

[0092] The detection portion electrode 229 is connected to the temperature sensor 227 , is made of a non-transient metal with high electrical conductivity, and can be removed together with the communication module 220 .

[0093] The temperature sensor 227 is driven by an analog method or a digital method, connected to the microcontroller unit MCU 223 in an analog I / O or digital I / O manner and provides temperature information, such as Figure 2 As shown, the electrode bandage module 210 is as close as possible to accurately monitor the temperature of the wound. The processor 240 is configured to verify that the impregnation of the user's target part 10 is in a supersaturated state when the temperature measurement value measured by the temperature sensor 227 is greater than or equal to the reference temperature, and to verify that the liquid of the user's target part 10 is in an unsaturated state when the temperature measurement value measured by the temperature sensor 227 is less than the reference temperature. The reference value of the temperature measurement value may be 40°C.

[0094] The first to third LDO regulators 224 to 226 supply power to the electrode wound dressing module 210 , and the electrode pattern 232 forms an electric field for transmitting electrical stimulation to the target site 10 of the user to induce wound treatment of the target site of the user.

[0095] The first LDO regulator 224 to the third LDO regulator 226 have different specifications. Specifically, the first LDO regulator 224, the second LDO regulator 225, and the third LDO regulator 226 are responsible for different loads. The microcontroller unit MCU 223 uses one of the first LDO regulator 224, the second LDO regulator 225, and the third LDO regulator 226, or two or more of the first LDO regulator 224, the second LDO regulator 225, and the third LDO regulator 226 to provide appropriate wound treatment to the target part 10 of the user.

[0096] As an example, the antenna 221 receives comprehensive treatment information from the electronic device 100, including wound information of the user's target part 10, user information, the operating time of the electrode module 230, and the treatment time of the electrode module 230. Afterwards, the microcontroller unit MCU 223 controls the electrode module 230 to form an electric field at the user's target part 10 to apply the operating time and treatment time of electrical stimulation based on the comprehensive treatment information received by the antenna 221 and based on the real-time clock (RTC) or external RTC, and controls the wound treatment time, voltage, and current through at least one of the first LDO regulator 224, the second LDO regulator 225, and the third LDO regulator 226 according to the electrical signal received from the electrode after the electrical stimulation, thereby adjusting the electrical stimulation degree and electrical stimulation time of the electrode pattern 232.

[0097] On the other hand, the smart bandage 200 for wound and wound treatment of the present invention is described as using three LDO regulators, but according to the design change of the smart bandage 200 for wound and wound treatment (for example, the size change of the smart bandage 200 for wound and wound treatment), different numbers of LDO regulators can be used in some embodiments. For example, the number of LDO regulators can be 1 to 5, but the present invention is not limited thereto.

[0098] The electrode module 230 may be provided at the electrode band-aid module 210 , made of a transient material, and form an electric field to apply electrical stimulation to the target site 10 and evaporate the impregnation substance of the target site 10 through the power supplied from the communication module 220 .

[0099] As an example, the electrode pattern 232 may be made of a transient material that may be decomposed over time and absorbed by the user over time. For example, materials that are conductive and harmless to the human body, such as nano-molybdenum (Mo), molybdenum disulfide (MoS2), tungsten disulfide (WS2), zinc oxide (ZnO), and magnesium oxide (MgO), may be used, but the present invention is not limited thereto.

[0100] Figure 5a and Figure 5b The figure is a cross-sectional view showing an electrode module of a smart bandage for treating trauma and wounds according to an embodiment of the present invention.

[0101] like Figure 5a and Figure 5b As shown, the electrode module 230 includes a nano-liposome 231 , an electrode pattern 232 and an electrode pad 233 .

[0102] The nanosome 231 may include poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [PHBV, Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)], polylactic acid (PLA, Poly lactic acid) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate)] composed of biodegradable biocontainers. acid], polycaprolactone (PCL), and at least one of the following: the triangle and the quadrilateral are composed of an enzyme, which produces a "living catalytic effect" through external vibration and electrical stimulation to accelerate the melting of the nano-liposome 231. The enzyme is characterized in that the material is decomposed by the electrode module 230 at a temperature above 38 degrees. The higher the density of the enzyme, the faster the catalytic effect and the faster the melting according to the external temperature, vibration, and electrical stimulation. In this case, the nano-liposome 231 is liquefied into a level of tens of μm with a wound treatment effect through electrical stimulation and hot temperature. The wound treatment agent liquefied by the enzyme has the advantage of allowing the drug with a therapeutic effect to penetrate the wound faster, and also plays a role in accelerating the rapid melting of the transient metal of the electrode module 230 to the user. The nano-liposome 231 can contain natural algae inflammation, polysaccharides as wound fillers, and at least one of polyurethane and lipase as artificial materials.

[0103] The nano-liposome 231 can receive power from the communication module 220 and connect the communication module 220 and the electrode pattern 232. As an example, the thickness of the nano-liposome 231 can be 50 μm to 75 μm.

[0104] As an example, the nano-liposome 231 is composed of two, and the electrode pattern 232 is between the two nano-liposomes 231 (see Figure 5b ).

[0105] The electrode pattern 232 forms an electric field by the power transmitted from the nano-liposome 231. This electric field applies electrical stimulation to the target site 10 of the user and evaporates the impregnation substance of the target site 10. By evaporating the impregnation substance of the target site 10 of the user, there is an effect of preventing the wound recovery of the target site 10 of the user from being delayed due to the impregnation substance of the target site 10 of the user.

[0106] As an example, the infiltrate evaporated by the electric field includes the user's exudate and the melt of the transient material melted by the user's heat.

[0107] As an example, the electrode pattern 232 has a thickness of 1 μm to 25 μm according to the size and extent of the wound. Preferably, the deeper and larger the wound is, the thicker the electrode pattern 232 is, and the shallower and smaller the wound is, close to 1 μm.

[0108] As an example, the electrode pattern 232 includes molybdenum (MO). In addition, the smart bandage according to an embodiment of the present invention further includes a molybdenum detection unit 266. The molybdenum detection unit 266 is provided in the communication module 220 and is used to detect the molybdenum of the target part 10 of the user. The processor 240 is configured to control the communication module 220 and the electrode module 230 to form an electric field for removing the molybdenum of the target part 10 of the user when it is determined that the impregnant is in an unsaturated state. At this time, the electric field of the target part 10 plays a role in promoting the removal of the molybdenum of the target part 10 of the user.

[0109] As an example, molybdenum is formed of a thin film with a thickness of 0.1 μm to 10 μm. In order to prevent excess or deficiency of molybdenum, the cross-sectional area of ​​the molybdenum is less than 10% of the target part of the user.

[0110] As an example, the electrode pattern 232 may include gelatin and hydrogel, and the melting speed is accelerated by the power and temperature transmitted from the nano-liposome 231. The gelatin and hydrogel accelerate the melting speed of fibroblasts of granulation tissue to quickly replace and cross-link collagen, thereby achieving rapid differentiation and growth.

[0111] As an example, the electrode pattern 232 has a two-dimensional structure. In this case, the electrode pattern 232 has a characteristic in the form of a magnetic field, and uses a pulsed induced current (Faradic current) to activate cells for effective treatment.

[0112] For example, the hydrogel may have a plurality of pores and be melted into a liquid by the body temperature of a living body after being attached to the living body.

[0113] As an example, if the biodegradable container used in the nano-liposome 231 is destroyed by external heat or electrode signals, the lipase meets the exudate with faster acceleration, and has the acceleration of complete liquefaction within one hour, which accelerates biological absorption and shortens the liquefaction of the hydrogel.

[0114] As an example, the electrode pattern 232 may have a three-dimensional structure. In this case, the electrode pattern 232 has electric field and magnetic field characteristics, and can exhibit more effective wound treatment characteristics compared to the case of using only the magnetic field.

[0115] As an example, an electrode pad 233 is attached to one side of the electrode pattern 232, and the other side of the electrode pad 233 contacts the user's target part 10. At this time, a rosin ester, a silicone layer, or a composite layer composed of a combination thereof is attached to the other side of the electrode pad 233 to improve the adhesion with the user's target part 10.

[0116] The electrode pad 233 is combined with the nano-liposome 231 and the electrode pattern 232, and is set on the attached surface of the electrode bandage module 210 in the target part 10 of the user, and contains at least one of a hydrogel and a hydrocolloid. The hydrogel and the hydrocolloid are melted by the user's body temperature of 30°C to 40°C. As an example, the thickness of the electrode pad 233 can be 30μm to 60μm. As another example, the electrode pad 233 receives power from the communication module 220 wirelessly.

[0117] As an example, the thickness and number of the electrode pads 233 can be differentiated and used according to the amount of exudate from the wound at the user's target site 10. Typically, the hydrophilic molecules in the hydrocolloid dressing absorb the exudate from the wound. However, the absorption of the exudate is limited, and when a large amount of exudate occurs, frequent replacement is required. However, the present invention evaporates the exudate by causing an infiltration phenomenon and exchange through the heat generated by the electrode pattern 232, thereby minimizing the replacement of the bandage due to saturation of the exudate. And, as described above, the heat generated by the electrode pattern 232 accelerates the melting rate of gelatin, hydrogel, etc. The present invention can compensate for the shortcomings of existing bandages by combining the electrode pattern 232 and the electrode pad 233.

[0118] As an example, the decomposition speed of the nano-liposome 231, the electrode pattern 232 and the electrode pad 233 may be different according to the user's body temperature. For example, the electrode pattern 232 is decomposed first, followed by the electrode pad 233, and finally the nano-liposome 231. For this reason, the thickness of the electrode pattern 232, the electrode pad 233, and the nano-liposome 231 may be increased in sequence. That is, the thickness may be electrode pattern 232 < electrode pad 233 < nano-liposome 231.

[0119] The processor 240 can detect the supersaturated state or unsaturated state of the impregnant of the user's target site 10, and control the communication module 220 and the electrode module 230. Specifically, the processor 240 can be configured to control the communication module 220 and the electrode module 230 to form an electric field at the user's target site 10 when it is determined that the impregnant is in a supersaturated state.

[0120] refer to Figure 1a and Figure 3 According to an embodiment of the present invention, the smart bandage further includes a ground connection portion 250, a feedback current measuring portion 261, a feedback voltage measuring portion 262, a humidity detection portion 264, a charge measurement portion 265, a molybdenum detection portion 266 and a friction electric generating device 270.

[0121] The ground connection part 250 is grounded to the user's target part 10. The ground connection part 250 becomes an electrical positive electrode and the user's target part 10 becomes an electrical negative electrode. Alternatively, the ground connection part 250 becomes an electrical negative electrode and the user's target part 10 becomes an electrical positive electrode.

[0122] The feedback current measuring unit 261 is electrically connected to the ground connection unit 250, and is used to measure the feedback current input to the ground connection unit 250 and fed back. At this time, the processor 240 can judge the supersaturated state or unsaturated state of the impregnation of the user's target part 10 based on the feedback current measured by the feedback current measuring unit 261. For example, the processor 240 is configured to judge that the impregnation of the user's target part 10 is in a supersaturated state when the feedback current value measured by the feedback current measuring unit 261 is 0 or less than or equal to the reference current. In addition, the processor 240 is configured to judge that the impregnation of the user's target part 10 is in an unsaturated state when the feedback current value measured by the feedback current measuring unit 261 is greater than or equal to the reference current. In addition, the reference current of the feedback current value may be 0.1 mA.

[0123] The feedback voltage measuring unit 262 is electrically connected to the ground connection unit 250, and is used to measure the feedback voltage input to the ground connection unit 250 and fed back. The processor 240 determines the supersaturated state or unsaturated state of the impregnation of the user's target part 10 based on the feedback voltage measured by the feedback voltage measuring unit 262. For example, the processor 240 is configured to determine that the impregnation of the user's target part 10 is in a supersaturated state when the feedback voltage value measured by the feedback voltage measuring unit 262 is 0 or less than or equal to the reference voltage. In addition, the processor 240 is configured to determine that the impregnation of the user's target part 10 is in an unsaturated state when the feedback voltage value measured by the feedback voltage measuring unit 262 is greater than or equal to the reference voltage. In addition, the reference voltage of the feedback current value may be 0.1V.

[0124] Only one of the feedback current measuring unit 261 and the feedback voltage measuring unit 262 may be provided, but the present invention is not limited thereto, and both the feedback current measuring unit 261 and the feedback voltage measuring unit 262 may be provided.

[0125] As an example, the processor 240 may be configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback current of the feedback current measuring unit 261 when the state of the impregnant determined by the feedback current measuring unit 261 is different from the state of the impregnant determined by the temperature sensor 227. Specifically, the processor 240 may be configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback current of the feedback current measuring unit 261 when the state of the impregnant determined by the feedback current measuring unit 261 is a supersaturated state and the state of the impregnant determined by the temperature sensor 227 is an unsaturated state. Furthermore, the processor 240 may be configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback current of the feedback current measuring unit 261 when the state of the impregnant determined by the feedback current measuring unit 261 is an unsaturated state and the state of the impregnant determined by the temperature sensor 227 is a supersaturated state.

[0126] As another example, the processor 240 may also be configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback voltage of the feedback voltage measuring unit 262 when the state of the impregnant determined by the feedback voltage measuring unit 262 is different from the state of the impregnant determined by the temperature sensor 227. Specifically, the processor 240 may be configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback voltage of the feedback voltage measuring unit 262 when the state of the impregnant determined by the feedback voltage measuring unit 262 is a supersaturated state and the state of the impregnant determined by the temperature sensor 227 is an unsaturated state. Furthermore, the processor 240 may be configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback voltage of the feedback voltage measuring unit 262 when the state of the impregnant determined by the feedback voltage measuring unit 262 is an unsaturated state and the state of the impregnant determined by the temperature sensor 227 is a supersaturated state.

[0127] The humidity detection unit 264 is provided in the communication module 220, and is used to detect the humidity of the target part 10. The processor 240 is configured to verify that the impregnation of the target part 10 of the user is in an unsaturated state when the humidity detected by the humidity detection unit 264 is less than the reference humidity, and to verify that the impregnation of the target part 10 of the user is in an oversaturated state when the humidity detected by the humidity detection unit 264 is greater than or equal to the reference humidity.

[0128] As an example, the humidity detection unit 264 is provided at one end connected to the nano-liposome 231 of the communication module 220 so as to be as close as possible to the user's target part 10. Therefore, the humidity detection unit 264 can measure the humidity of the user's target part 10 as accurately as possible.

[0129] As an example, the processor 240 is configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback current of the feedback current measuring unit 261 when the state of the impregnant determined by the feedback current measuring unit 261 is different from the state of the impregnant determined by the humidity detecting unit 264. Specifically, the processor 240 is configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback current of the feedback current measuring unit 261 when the state of the impregnant determined by the feedback current measuring unit 261 is a supersaturated state and the state of the impregnant determined by the humidity detecting unit 264 is an unsaturated state. Furthermore, the processor 240 is configured to re-determine the supersaturated state or unsaturated state of the impregnant by re-measuring the feedback current of the feedback current measuring unit 261 when the state of the impregnant determined by the feedback current measuring unit 261 is an unsaturated state and the state of the impregnant determined by the humidity detecting unit 264 is a supersaturated state.

[0130] The charge measuring unit 265 may be electrically connected to the ground connection unit 250, and measure the charge characteristics of the target site 10 through the ground connection unit 250. The processor 240 is configured to determine that the impregnant is in an oversaturated state when the charge characteristics of the target site 10 measured by the charge measuring unit 265 are negative charges, and to determine that the impregnant is in an unsaturated state when the charge characteristics of the target site 10 measured by the charge measuring unit 265 are positive charges.

[0131] The triboelectric generator 270 may be provided at the communication module 220 to supply triboelectricity generated by friction due to ultrasonic irradiation as electric power to the communication module 220 .

[0132] Figure 6 It is a schematic diagram showing the wound treatment process of the smart bandage 200 for wound and wound treatment according to an embodiment of the present invention.

[0133] First, the smart bandage 200 for wound and wound treatment is attached to the user's target part 10. At this time, the electrode pattern 232 can be inserted into the wound of the user's target part 10, and the electric field formed by the electrode pattern 232 provides a negative charge electrical stimulation signal to the epidermis and dermis for healing. The signal stimulates growth factors, and the growth factors stimulate granulation tissue with fibroblasts (see S10).

[0134] In this process, a substance capable of absorbing the exudate as the impregnation of the target part of the user and the transient material of the melted electrode module 230 is required, and the hydrogel or hydrocolloid contained in the electrode pad 233 can be used to absorb the impregnation. The hydrocolloid or hydrogel contained in the electrode pad 233 absorbs the impregnation and creates a moist environment. When the transient material applies electrical stimulation to the wound of the target part 10 of the user, the vaporization of the impregnation occurs while generating heat, and is sent to the external barrier with the help of porous polyethylene in contact with the hydrocolloid (or, hydrogel). This vaporization process plays a role in reducing excessive impregnation, and the heat generated in the process of accelerating wound recovery is generated by applying electrical stimulation using the transient material to quickly cool it.

[0135] On the other hand, the melting speed of the hydrocolloid of the electrode pad 233 melted by the user's body temperature is accelerated, and the collagen such as pectin and gelation contained in the electrode pad 233 meets the wound, and the fibroblasts become new capillaries. In addition, since the transient material is absorbed by the user, the electrical stimulation applied by the electrode pattern 232 to the user's target part 10 is significantly reduced from the intermediate stage. This ultimately produces an effect similar to that of sutures, and this feature improves resistance to healing complications (infection), and both functionality and aesthetics are improved (see S20).

[0136] Afterwards, the processor 240 detects the supersaturated state or unsaturated state of the impregnation substance of the user's target site 10, and determines whether to form an additional electric field at the user's target site 10. Specifically, when the processor 240 determines that the impregnation substance is in the supersaturated state, it controls the communication module 220 and the electrode module 230 to form an additional electric field. As a result, by evaporating the impregnation substance of the user's target site 10, the wound recovery of the user's target site 10 is prevented from being delayed due to the impregnation substance of the user's target site 10 (see S30).

[0137] As an example, when the processor 240 determines that the impregnant is in an oversaturated state, it can make a first judgment through one of the feedback current measuring unit 261, the feedback voltage measuring unit 262 and the charge measuring unit 265, and then verify it through one of the temperature sensor 227 and the humidity detection unit 264.

[0138] As another example, when the processor 240 determines that the impregnant is in an oversaturated state, it can make a first judgment through two of the feedback current measuring unit 261, the feedback voltage measuring unit 262 and the charge measuring unit 265, and then verify it through one of the temperature sensor 227 and the humidity detection unit 264.

[0139] Afterwards, the molybdenum detection unit 266 detects the molybdenum of the user's target site 10. This is to confirm whether the molybdenum component of the electrode pattern 232 remains in the user's target site 10. The processor 240 may be configured to control the communication module 220 and the electrode module 230 to form an electric field for removing the molybdenum from the user's target site 10 when it is determined that the impregnant is in an unsaturated state. The molybdenum can accelerate the melting speed by the user's body temperature (see S40).

[0140] As an example, when removing the smart band-aid, the electrode band-aid module 210 and the communication module 220 can be separated from the user's target part 10 together, or only the communication module 220 can be separated from the user's target part 10, and then the electrode band-aid module 210 can be separated from the user's target part 10 after the electrode module 230 is completely melted by the user's biological heat.

[0141] Specifically, the electrode bandage module 210 and the communication module 220 may be separated from the target part 10 of the user together in a state where the electrode module 230 located at the target part 10 of the user is completely melted by the biological heat of the user.

[0142] Furthermore, when the electrode module 230 located at the target part 10 of the user has not been completely melted by the biological heat of the user, only the communication module 220 is separated from the target part 10 of the user, and then the electrode band-aid module 210 is separated from the target part 10 of the user after the electrode module 230 is completely melted by the biological heat of the user.

[0143] On the other hand, if the hydrogel of the electrode module 230 is not completely melted for a long time, the processor can control the communication module 220 and the electrode module 230 to form an electric field for removing the hydrogel of the electrode module 230 of the target part 10 of the user.

[0144] Figure 7 The figure is used to illustrate the test results of the current transmission rate of the smart band-aid for treating wounds and injuries capable of self-healing according to one embodiment of the present invention.

[0145] As wound healing progresses, the current used for wound healing tends to decrease. This is simply because as the wound heals, the internal current of the living body increases, resulting in increased resistance to the externally supplied current, and the more the transient bionic material melts to heal the wound, the lower the current transmission efficiency. Finally, since the wound exudate has a high hydrophilicity, the current transmission rate is high. As the wound heals, the exudate decreases and the current transmission effect also decreases.

[0146] Figure 7The graph shows the results of testing the current transfer rate of the wound in two ways. The two ways are the method 710 using only electrodes and the method 720 using electrodes + hydrocolloids. Among them, the case of the method 720 using electrodes + hydrocolloids shows a faster treatment effect. In the early stage of wound treatment, there is no significant difference due to the small amount of exudate, but after 24 hours (1 day), the exudate of the wound increases rapidly. The smart bandage 200 for trauma and wound treatment of the present invention adopts the method 720 using electrodes + hydrocolloids. As the wound treatment proceeds, there is more exudate formed by liquefaction of hydrocolloids, thereby showing a higher current transfer rate.

[0147] Figure 8 The figure is used to illustrate the test results of the wound treatment effect of the smart bandage for self-healing trauma and wound treatment according to one embodiment of the present invention.

[0148] Figure 8 The graphs show the test results of wound healing in three ways, namely, a method using only electrodes 810, an electrode + hydrocolloid method 820, and a natural healing method 830.

[0149] Since the natural healing method 830 showed an effect of up to 75% of skin tension, the test was compared with 75% of the wound recovery ability of the natural healing method 830 as a benchmark. The proposed method (electrode + hydrocolloid method 820) showed an effect of up to 72~73% within 12 days, so it was compared with each other within the same range (12 days). Generally, even if the wound is treated with the electrode + hydrocolloid method, the wound recovery ability can only be improved to 85%. In the method 810 using only electrodes without hydrocolloids, although the verification reaction is minimized by reducing the infiltration of pathogens in the sterile cavity as much as possible, there is also the influence of wound crust caused by air in this case. Reflecting these factors, the excellent wound recovery ability of the electrode + hydrocolloid method 820 was verified through a 12-day test.

[0150] According to the present invention, the smart bandage 200 for trauma and wound treatment according to one embodiment of the present invention and the smart bandage control system containing the same accelerate the redox reaction of the wound by applying electrical stimulation to the wound, and evaporate the supersaturated impregnation material in the user's target part 10, thereby preventing the wound recovery of the user's target part 10 from being delayed due to the supersaturated impregnation material generated in the user's target part 10.
