[0001] This invention relates to an electrode patch for wound treatment and a wound treatment device using high-voltage pulsed current stimulation. Background Technology

[0002] Typically, wound treatment primarily utilizes negative pressure wound therapy, hyperbaric oxygen therapy, debridement, and electro- / electromagnetic therapy. Among these, negative pressure wound therapy is the most commonly used method. It applies negative pressure to the wound site to absorb exudates such as blood and pus, and promotes blood circulation to the wound, thereby inducing wound healing.

[0003] On the other hand, such as Figure 1 As shown, there is an electrotherapy method in which electrodes 30 and 40 are attached to the skin around the wound 20, and the device 50 applies an electric current to the electrodes 30 and 40 to make the current flow around the wound, thereby helping the wound to heal.

[0037] The terms or words used in this specification and claims should not be interpreted in a way that is conventional or dictionary-sounding, but rather should be interpreted in accordance with the meaning and concept of the invention, based on the principle that the inventors may appropriately define the terms to best illustrate their invention.

[0038] Therefore, the embodiments described in this specification and the structures shown in the accompanying drawings are only preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. It should be understood that at the time of this application, there may be various equivalents and modifications that can replace these embodiments.

[0039] The electrode patch and wound treatment device for wound treatment according to embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily implement the invention.

[0040] Figure 2 This is a schematic diagram illustrating an electrode patch according to an embodiment of the present invention. Figure 3 It is used to explain Figure 2 The diagram shows the electrode patch cut to size according to the wound.

[0041] like Figure 2 As shown, the electrode patch 100 involved in the embodiment of the present invention includes: a first electrode portion, a second electrode portion, and an exudate absorption component 140.

[0042] The first electrode section includes: a first connecting electrode 110, a first base electrode 111, a first-1 branch electrode 112, a first-2 branch electrode 113, a first-3 branch electrode 114, a first-4 branch electrode 115, and a first-5 branch electrode 116; the second electrode section includes: a second connecting electrode 120, a second base electrode 121, a second-1 branch electrode 122, a second-2 branch electrode 123, a second-3 branch electrode 124, a second-4 branch electrode 125, and a second-5 branch electrode 126.

[0043] The first connecting electrode 110 and the second connecting electrode 120 are arranged longitudinally and have a connection portion at the lower end that can receive voltage from the outside.

[0044] The first base electrode 111 extends horizontally to the left from the first connection electrode 110, and the first-1 to first-5 branch electrodes 112 to 116 branch out from the first base electrode 111 at regular intervals. The first-2 to first-5 branch electrodes 113 to 116 extend longitudinally from the first base electrode 111 and are formed in a substantially semicircular or "匚" shape. The first-1 branch electrode 112 extends longitudinally a short distance from the first connection electrode 110.

[0045] The second base electrode 121 extends horizontally to the right from the second connection electrode 120, and the second-1 to second-5 branch electrodes 122 to 126 branch out from the second base electrode 121 at regular intervals. The second-1 to second-5 branch electrodes 122 to 126 extend longitudinally from the second base electrode 121 and are formed in a substantially semicircular or "匚" shape.

[0046] The first-1 to first-5 branch electrodes 112 to 116 and the second-1 to second-5 branch electrodes 122 to 126 are arranged alternately. For example, the second-1 branch electrode 122 is disposed between the first-1 branch electrode 112 and the first-2 branch electrode 113, and the second-2 branch electrode 123 is disposed between the first-2 branch electrode 113 and the first-3 branch electrode 114. Similarly, from the perspective of the second electrode portion, the first-2 branch electrode 113 is disposed between the second-1 branch electrode 122 and the second-2 branch electrode 123. The remaining branch electrodes are also arranged in the same manner as Figure 2 shown.

[0047] By configuring in this way, when the first electrode portion and the second electrode portion are covered on the wound site, the wound site can be densely covered, so the treatment effect can be further enhanced. Different from the existing electrode patch that is placed around the wound site to apply electrical stimulation to the wound, the electrode patch 100 according to the embodiment of the present invention is directly placed above the wound site, so that electrical stimulation can be directly applied to the wound. Therefore, the electrical stimulation can directly act on the wound, and its effect is much greater than that of stimulating from the surrounding.

[0048] The first electrode portion and the second electrode portion are composed of a thin film made of a conductor such as gold, silver, platinum, etc., and are attached and fixed to the exudate absorption component 140. The widths of these electrodes are basically the same, and the distances between adjacent electrodes are also basically the same.

[0049] [[ID=!]]The exudate absorption component 140 absorbs the exudate flowing out from the wound site, can be formed of hydrogel, and can be made of a breathable material capable of transmitting negative pressure. In addition, the exudate absorption component 140 supports the first electrode portion and the second electrode portion, and enables the first electrode portion and the second electrode portion to closely adhere to the wound site by applying pressure from the rear.

[0050] This electrode patch 100 can be manufactured as follows.

[0051] First, to form electrodes that directly contact the wound, an electrode coating is formed on a polymer film such as PE or PET using materials such as platinum, gold, silver, or carbon. This electrode coating is created using vapor deposition or electroplating. After forming the electrode coating, to apply negative pressure between the electrodes, a perforated structure is created in the portion outside the electrodes, including the area between them. The electrode-coated film is then attached to the exudate absorption component using biocompatibility double-sided tape or adhesive, integrating them into the structure. Cutting lines are marked on the electrodes or the exudate absorption component as needed.

[0052] On the other hand, the size of the electrode patch can be adjusted by cutting the first base electrode 111, the second base electrodes 111, 121, and the branch electrodes according to the size of the wound. For ease of cutting, cutting lines 130 can be marked on the first and second base electrodes 111, 121 and the exudate absorption member 140. The size of the electrode patch 100 can be easily adjusted simply by cutting along the cutting lines 130 with scissors. According to the embodiment of the present invention, even when the electrode pattern of the electrode patch 100 is cut along the cutting lines 130 to fit the wound size, the electrodes remaining inside will not break, except for the cut-off outer electrodes.

[0053] Figure 3 (a) shows an electrode patch cut along the cutting line 130a between the first-second branch electrode 113 and the second-second branch electrode 123, corresponding to the size of wound 11. Figure 3 (b) shows an electrode patch cut along the cutting line 130b between the first-third branch electrode 114 and the second-third branch electrode 124, corresponding to the size of wound 12. Figure 3 (c) shows an electrode patch cut along the cutting line 130c between the first-fourth branch electrodes 115 and the second-fourth branch electrodes 125, corresponding to the size of wound 13. Figure 3 (d) shows an uncut electrode patch corresponding to the size of wound 14. The branched electrodes can completely cover the wound, allowing current to flow through the wound site by covering it in an appropriate size, which is more effective for wound treatment.

[0054] Thus, the electrode patch 100 according to the embodiments of the present invention can be appropriately cut and used according to the size of the wound, so even if there is only one electrode patch, it can cope with wounds of various sizes.

[0055] Below, refer to Figures 4 to 6This invention provides a detailed description of a wound treatment device according to embodiments thereof, which uses such an electrode patch 100 to apply electrical stimulation to a wound to aid in wound treatment.

[0056] Figure 4 This is a block diagram illustrating a wound treatment device according to an embodiment of the present invention. Figure 5 It is shown Figure 4 A diagram of the electrode patches used in the process. Figure 6 This is a diagram showing the electrical waveforms applied to the electrode patch according to an embodiment of the present invention.

[0057] like Figure 4 As shown, an embodiment of the wound treatment device 500 of the present invention includes: an electrode patch 100, a main body 170, and a vacuum section 180. The main body 170 includes: a control device 171, a current application device 175, a vacuum pump 172, a negative pressure sensor 174, and a negative pressure valve 173.

[0058] like Figure 5 As shown, the electrode patch 100 has connecting portions 111 and 121 at the ends of the connecting electrodes 110 and 120, and is connected to the wire 160 by means of rivets or the like. The end of the wire 160 is composed of a one-touch connector 165 and is connected to the main body 170.

[0059] The electrode patch 100 covers the wound 10, and the electrode is placed directly on the wound. An exudate absorption component 140 is disposed on the electrode. The fixing seal 150 is made of a film or the like and is used to fix the periphery of the wound 10 with an adhesive to seal it while the electrode patch 100 is covering the wound 10, so as to maintain negative pressure at the wound 10.

[0060] The vacuum section 180 transmits the vacuum pressure applied from the main body 170 to the interior of the fixed seal 150 to maintain a negative pressure inside the fixed seal 150.

[0061] Vacuum pump 172 is used to draw air from the wound site covered by vacuum section 180 and electrode patch 100, thereby generating negative pressure at the wound site. Negative pressure valve 173 is used to adjust the negative pressure generated at the wound site to a reference negative pressure. Negative pressure sensor 174 senses negative pressure at the negative pressure generation site and sends the pressure value to control device 171. Current application device 175 applies current to the electrodes within electrode patch 100. Figure 6The waveform shown is an electrical device. Control device 171 controls these components and adjusts negative pressure valve 173 using the pressure value received from negative pressure sensor 174 to maintain an appropriate reference negative pressure at the wound site covered by electrode patch 100. While maintaining the reference negative pressure at the wound site, it instructs current application device 175 to apply current, thus supplying direct current to electrode patch 100. The resulting negative pressure not only effectively absorbs exudate at the wound site 10 but also ensures that electrode patch 100 adheres tightly to the wound site 10, thereby enabling the electrical stimulation generated by the electrodes to be effectively transmitted to the wound site 10.

[0062] At this time, the electricity applied to wound 10 is direct current and is a high voltage pulsed current (HVPC). Figure 6 The electrical waveform shown is an example. The voltage ranges from 100 to 500V. The duration of a single pulse (A) is 1 μs to 100 μs, the pulse interval (B) is 100 ms to 10 sec, the duration of a single polarity pulse (C) is 2.5 min to 30 min, the electrode switching time (D) is 200 μs to 1 ms, the duration of a pulse train (i.e., the time for one treatment) is 5 min to 60 min, and the pulse train interval is 1 h to 12 h.

[0063] Electrical stimulation is known to aid in multiple stages of skin wound healing through various mechanisms, particularly when high voltage is used. High-voltage currents have strong skin penetration, and HVPC electrical stimulation is more effective for wound treatment due to the galvanotaxis phenomenon, where dermal fibroblasts migrate towards the cathode in proportion to the applied voltage.

[0064] By reversing the polarity of the electrodes, the current flows alternately from one direction (positive) to the opposite direction (negative) and then back again, thus achieving uniform stimulation. With alternating current or ultrasound stimulation, energy vibrations cause cells or intercellular substances in the skin tissue to vibrate, generating heat, making it difficult to stimulate infectious agents such as cells or bacteria in a specific direction. However, direct current can stimulate cells or infectious agents in a specific direction, and by changing the electrode direction, stimulation can also be achieved in the opposite direction. This polarity reversal is more effective for wound treatment.

[0065] Below, refer to Figure 7 and Figure 8 An electrode patch according to another embodiment of the present invention will be described. Figure 7 This is a schematic diagram illustrating an electrode patch according to another embodiment of the present invention. Figure 8 It is shown Figure 7The figure shows another method for cutting the electrode patch.

[0066] Figure 7 (a) is a small-sized electrode patch 200, which has a first connecting electrode 202 and a second connecting electrode 203, a first base electrode and a second base electrode, a branch electrode and an exudate absorption component 204, and is marked with cutting lines 201a and 201b.

[0067] Figure 7 (b) is a medium-sized electrode patch 210, which has a first connecting electrode 212 and a second connecting electrode 213, a first base electrode and a second base electrode, a branch electrode and an exudate absorption component 214, and is marked with cutting lines 211a and 211b.

[0068] Figure 7 (c) is a large-sized electrode patch 220, which has a first connecting electrode 222 and a second connecting electrode 223, a first base electrode and a second base electrode, a branch electrode and an exudate absorption component 224, and is marked with cutting lines 221a, 221b and 221c.

[0069] Electrode patch 200 has 4 branch electrodes, electrode patch 210 has 6 branch electrodes, and electrode patch 220 has 7 branch electrodes. Since the distance between the branch electrodes of electrode patches 200, 210, and 220 is constant, the more branch electrodes, the larger the size. Each electrode patch 200, 210, and 220 can be cut to size along cutting lines 201, 211, and 221 according to the wound size. Because electrode patches 200, 210, and 220 are available in large, medium, and small sizes, and each electrode patch can be cut to size according to the wound size, electrode patches of appropriate size can be made for use on wounds of any size.

[0070] The electrode patches 200, 210, and 220 are basically the same as the electrode patch 100 in the aforementioned embodiment, except that they are elliptical in shape and different in size. Therefore, detailed descriptions are omitted.

[0071] The cutting lines for electrode patches 200, 210, and 220 do not need to be limited to between branch electrodes; they can be adjusted according to wound size or patient condition. Figure 8 The electrode patches can be cut horizontally or vertically for use. However, in this case, not only the outer part of the cut branch electrode, but also its inner part may fail to supply power, so precise cutting is required according to the size of the wound.

[0072] Below, refer to Figure 9 and Figure 10 The electrode patch according to another embodiment of the present invention will be described in detail.

[0073] Another embodiment of the present invention relates to an electrode patch 300 comprising: a first electrode portion, a second electrode portion, an exudate absorption component 350, and an insulating component 340.

[0074] The first electrode section includes: a first connecting electrode 310, a first base electrode 311, a first-1 branch electrode 312, a first-2 branch electrode 313, a first-3 branch electrode 314, a first-4 branch electrode 315, a first-5 branch electrode 316, a first-6 branch electrode 317, and a first-7 branch electrode 318; the second electrode section includes: a second connecting electrode 320, a second base electrode 321, a second-1 branch electrode 322, a second-2 branch electrode 323, a second-3 branch electrode 324, a second-4 branch electrode 325, a second-5 branch electrode 326, a second-6 branch electrode 327, and a second-7 branch electrode 328.

[0075] The first connecting electrode 310 and the second connecting electrode 320 are arranged longitudinally and have a connection portion at the lower end that can receive voltage from the outside.

[0076] The first base electrode 311 extends laterally from the first connecting electrode 310 to the left and right, and the first-1 to the first-7 branch electrodes 312 to 318 branch out from the first base electrode 311 at certain intervals and extend longitudinally in a straight line shape.

[0077] The second base electrode 321 extends laterally from the second connecting electrode 320 to the left and right, and the second-1 to second-7 branch electrodes 322 to 328 branch out from the second base electrode 321 at certain intervals and extend longitudinally in a straight line shape.

[0078] At the first base electrode 311 and the second base electrode 321, and at the branch electrode portions from which they branch, the first electrode portions and the second electrode portions overlap, but an insulating member 340 is provided between them, so they are not electrically connected. The branch electrodes that do not overlap outside the insulating member 340 are arranged alternately with a certain interval between them, and become the part covering the wound site.

[0079] The first electrode portion, the second electrode portion, and the insulating component 340 are attached and fixed to the exudate absorption component 350.

[0080] The electrode patch 300 involved in the embodiments of the present invention, since the branch electrodes are linear, can be cut to an appropriate size along the horizontal and vertical directions according to the size of the wound, without the need to specifically mark the cutting lines 331, 332, 333, and 334. Furthermore, the electrode patch 300 can also be cut along a diagonal direction or in a circle, rather than along the horizontal and vertical directions.

[0081] like Figure 10 As shown, it can be appropriately cut in both the transverse and longitudinal directions according to the size of the wound 15, thus simplifying its use and allowing electrical stimulation to be applied to the entire area inside the cut.

[0082] Figure 11 This is a schematic diagram illustrating an electrode patch according to another embodiment of the present invention.

[0083] Figure 11 The electrode patch 400 shown in another embodiment of the present invention includes: a first electrode portion 410, a second electrode portion 420, an exudate absorption component 440, a first insulating component 430, and a second insulating component 450.

[0084] The first electrode portion 410 and the second electrode portion 420 are substantially the same as the electrode portions in the electrode patch 300 of the aforementioned embodiment, except that the number and size of the branch electrodes may be different, so their description is omitted.

[0085] The portion of the first electrode 410 bonded to the exudate absorption member 440 is positioned below, and the portion of the second electrode 420 bonded to the first insulating member 430 is positioned above, with the first insulating member 430 placed above the first electrode 410 for bonding. Then, the second insulating member 450 is bonded above the second electrode 420 after such bonding.

[0086] A plurality of holes 435 are drilled in the first insulating member 430, and these holes are located above the branch electrodes of the first electrode portion 410. Therefore, the branch electrodes of the first electrode portion are exposed through these holes 435.

[0087] Multiple holes 455 are also drilled in the second insulating member 450, overlapping with the holes 435 in the first insulating member 430. Through these holes 455, the branch electrodes of the first electrode portion 410 are exposed. Furthermore, these holes 455 are drilled above the branch electrodes of the second electrode portion 420, exposing the branch electrodes of the second electrode portion 420. Figure 11 As shown, the shape, size, number, and arrangement of holes 435 and 455 can be selected in various ways as needed.

[0088] Therefore, the branch electrodes of the first electrode portion 410 and the branch electrodes of the second electrode portion 420 are exposed through holes 435 and 455, covering the wound and allowing electrical stimulation to be applied through them. The unexposed portions are electrically isolated by the first insulating member 430 and the second insulating member 450.

[0089] The point electrodes generated by this electrode patch 400 can effectively generate an electric field while minimizing rejection reactions in electrically sensitive patients.

[0090] The electrode patch 400 involved in the embodiments of the present invention, like the electrode patch 300 in the aforementioned embodiments, can be cut and used relatively freely according to the size of the wound and the condition of the patient.

[0091] Below, refer to Figures 12 to 14 This describes the results of experiments conducted to demonstrate the therapeutic effect of the wound treatment device according to the embodiments of the present invention. Figure 12 These are photographs showing the experimental appearance of the mice used in this experiment. Figure 13 This is a comparison chart showing the application of electricity and the absence of electricity application, based on embodiments of the present invention. Figure 14 These are experimental photographs comparing the application of electricity and the absence of electricity application as described in the embodiments of the present invention.

[0092] <Experiment>

[0093] like Figure 12 As shown, two 8mm wounds were created on the experimental mice. The left wound was left untreated, while the right wound was subjected to electrical stimulation for 15 minutes each day for 5 working days, according to an embodiment of the present invention, for a total of 2 weeks. The electrical stimulation conditions were: voltage 130V, pulse duration 25μs, and pulse repetitions 1800 times × 2 times (1800 times for the positive electrode and 1800 times for the negative electrode).

[0094] The wound size was measured daily based on the wound healing progress. After 7 days, the wound was sampled, cultured in a culture medium, and the bacterial count (CFU) was observed.

[0095] As a result, Figure 13 As shown in the graph, which is a chart of wound area related to trauma recovery, the height of the right bar (black) with applied electricity in the embodiment of the present invention is lower than the height of the left bar (green) without applied electricity. This means that wound healing is faster and the wound size is smaller when electricity is applied.

[0096] In addition, such as Figure 14 As shown, it can be confirmed that the number of bacteria was significantly reduced in the case of electrical stimulation (+ES) compared with the case of no electrical stimulation (-ES).

[0097] Thus, through experiments on actual laboratory mice, it can be confirmed that the wound treatment device involved in the embodiments of the present invention not only has strong wound skin regeneration ability, but also significantly reduces bacterial proliferation.
