Specific details for implementing the invention

[0019] Terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0020] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0021] Hereinafter, with reference to the attached drawings, an electrode patch for wound treatment and a wound treatment device according to an embodiment of the present invention will be described in detail so that those skilled in the art can easily implement the present invention.

[0022] FIG. 2 is a schematic diagram illustrating an electrode patch according to one embodiment of the present invention, and FIG. 3 is a diagram for explaining the electrode patch illustrated in FIG. 2 cut according to the size of the wound.

[0023] As illustrated in FIG. 2, an electrode patch (100) according to an embodiment of the present invention includes a first electrode portion, a second electrode portion, and an exudate absorption member (140).

[0024] 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), and 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).

[0025] The first and second connecting electrodes (110, 120) are arranged in a vertical direction and are provided with a connection portion at the bottom that can receive voltage from an external source.

[0026] The first base electrode (111) extends horizontally to the left from the first connecting electrode (110), and at regular intervals, the first-1 to first-5 branch electrodes (112 to 116) branch off from the first base electrode (111). The first-2 to first-5 branch electrodes (113 to 116) extend vertically from the first base electrode (111) and form a roughly semicircular or U-shape. The first-1 branch electrode (112) extends briefly in a column direction from the first connecting electrode (110).

[0027] The second base electrode (121) extends horizontally to the right from the second connecting electrode (120), and at regular intervals, the 2-1 to 2-5 branch electrodes (122 to 126) branch off from the second base electrode (121). The 2-1 to 2-5 branch electrodes (122 to 126) extend from the second base electrode (121) in a linear direction and are formed in a roughly semicircular or U-shape.

[0028] The 1-1 to 1-5 branch electrodes (112 to 116) and the 2-1 to 2-5 branch electrodes (122 to 126) are arranged alternately. For example, the 2-1 branch electrode (122) is placed between the 1-1 branch electrode (112) and the 1-2 branch electrode (113), and the 2-2 branch electrode (123) is placed between the 1-2 branch electrode (113) and the 1-3 branch electrode (114). Likewise, from the perspective of the 2 electrode section, the 1-2 branch electrode (113) is placed between the 2-1 branch electrode (122) and the 2-2 branch electrode (123). The remaining branch electrodes are also arranged in the same manner as shown in FIG. 2.

[0029] By being arranged in this manner, the first electrode and the second electrode can densely cover the wound area when placed over it, thereby increasing the therapeutic effect. Unlike conventional electrode patches that are placed around the wound area to provide electrical stimulation to the wound, the electrode patch (100) according to the embodiment of the present invention can be placed directly over the wound area to provide electrical stimulation to the wound. Therefore, the electrical stimulation can be direct to the wound, and the effect is much greater than stimulation from the surrounding area.

[0030] The first electrode and the second electrode are made of thin films of conductors such as gold, silver, and platinum, and are attached to and fixed to the exudate absorption member (140). The widths of these electrodes are almost identical, and the distance between adjacent electrodes is also almost identical.

[0031] The exudate absorption member (140) absorbs exudate coming from the wound site and may be made of a hydrogel and may be made of an air-permeable material to transmit negative pressure. Additionally, the exudate absorption member (140) supports the first and second electrodes and applies pressure from the rear so that the first and second electrodes can adhere to the wound site.

[0032] These electrode patches (100) can be manufactured as follows.

[0033] First, to form an electrode that comes into direct contact with the wound, an electrode coating is formed using materials such as platinum, gold, silver, or carbon on a polymer film made of PE or PET. At this stage, deposition or plating methods are used to form the electrode coating. After forming the electrode coating, a perforated structure is created in the parts excluding the electrodes, including the spaces between them, so that negative pressure can be applied between the electrodes. The electrode-coated film is then attached to an exudate-absorbing member using biocompatible double-sided tape or adhesive to integrate them. If necessary, a perforation line is marked on the electrode or on the exudate-absorbing member.

[0034] Meanwhile, the size of the electrode patch can be adjusted by cutting between the first and second base electrodes (111, 121) and the branch electrode according to the size of the wound area. For convenience of cutting, a cutting line (130) can be marked on the first and second base electrodes (111, 121) and the exudate absorption member (140). Since it is only necessary to cut along the cutting line (130) with scissors, the size of the electrode patch (100) can be easily adjusted. According to the electrode pattern of the electrode patch (100) according to the embodiment of the present invention, even if it is cut along the cutting line (130) to fit the size of the wound, the electrodes remaining inside, excluding the cut-out external electrodes, are not severed.

[0035] FIG. 3(a) shows an electrode patch cut along a cut line (130a) between the first-2 branch electrode (113) and the second-2 branch electrode (123) corresponding to the size of the wound (11); FIG. 3(b) shows an electrode patch cut along a cut line (130b) between the first-3 branch electrode (114) and the second-3 branch electrode (124) corresponding to the size of the wound (12); FIG. 3(c) shows an electrode patch cut along a cut line (130c) between the first-4 branch electrode (115) and the second-4 branch electrode (125) corresponding to the size of the wound (13); and FIG. 3(d) shows an electrode patch that is not cut corresponding to the size of the wound (14). It is more effective for wound treatment if the branch electrodes can completely cover the wound, but cover the wound with an appropriate size and pass an electric current to the wound area.

[0036] As such, according to the electrode patch (100) according to the embodiment of the present invention, since it can be appropriately cut and used according to the size of the wound, it is possible to handle wounds of various sizes with only one electrode patch.

[0037] Then, a wound treatment device according to an embodiment of the present invention, which can help treat a wound by applying electrical stimulation to the wound using such an electrode patch (100), will be described in detail with reference to FIGS. 4 to 6.

[0038] FIG. 4 is a block diagram illustrating a wound treatment device according to one embodiment of the present invention, FIG. 5 is a diagram illustrating an electrode patch used in FIG. 4, and FIG. 6 is a diagram illustrating an electric waveform applied to an electrode patch according to an embodiment of the present invention.

[0039] As illustrated in FIG. 4, a wound treatment device (500) according to one embodiment of the present invention comprises an electrode patch (100), a main body (170), and a vacuum unit (180). The main body (170) comprises a control device (171), a current application device (175), a vacuum pump (172), a negative pressure sensor (174), and a negative pressure valve (173).

[0040] As shown in FIG. 5, the electrode patch (100) is provided with a connecting part (111, 121) at the end of the connecting electrode (110, 120) and is connected to a wire (160) using a rivet or the like, and the end of the wire (160) is made of a one-touch connector (165) and connected to the main body (170).

[0041] An electrode patch (100) is placed over a wound (10) area, with the electrode placed directly over the wound and an exudate-absorbing member (140) placed over the electrode. A fixing seal (150) is made of a film or the like to seal the area around the wound (10) with an adhesive while the electrode patch (100) is placed over the wound (10) area, and to maintain negative pressure on the wound (10) area.

[0042] The vacuum section (180) transmits the vacuum pressure applied from the main body (170) into the fixed seal (150) so that negative pressure is maintained inside the fixed seal (150).

[0043] The vacuum pump (172) is a pump used to generate negative pressure in the wound area by extracting air from the wound area covered by the vacuum section (180) and the electrode patch (100). The negative pressure valve (173) is a valve that regulates the negative pressure generated in the wound area to become a reference negative pressure. The negative pressure sensor (174) detects the negative pressure at the area where the negative pressure is generated and sends the pressure value to the control device (171). The current application device (175) is a device that applies electricity of the waveform shown in FIG. 6 to the electrode inside the electrode patch (100). The control section (171) controls these to regulate the negative pressure valve (173) using the pressure value received from the negative pressure sensor (174) so ​​that an appropriate reference negative pressure is maintained in the wound area covered by the electrode patch (100), and commands the current application device (175) to apply electricity so that direct current electricity flows through the electrode patch (100) while the reference negative pressure is maintained in the wound area. The negative pressure generated in this way not only effectively sucks up exudate from the wound (10) area, but also causes the electrode patch (100) to adhere closely to the wound (10) area, allowing electrical stimulation by the electrode to be effectively transmitted to the wound (10).

[0044] At this time, the electricity applied to the wound (10) is direct current and is a High Voltage Pulsed Current (HVPC). The electric waveform shown in FIG. 6 is an example with a voltage magnitude of 100 to 500 V, a pulse duration (A) of 1 μs to 100 μs, an interval between pulses (B) of 100 ms to 10 sec, a pulse duration (C) of 2.5 min to 30 min, an electrode switching time (D) of 200 μs to 1 ms, a pulse duration, that is, a time to perform one procedure, of 5 min to 60 min, and an interval between pulses of 1 h to 12 h.

[0045] Electrical stimulation is known to be helpful in the healing of skin wounds by acting in various ways at multiple stages, and is particularly more efficient when high voltage is used. High-voltage current has excellent skin penetration power, and electrical stimulation by HVPC is much more effective for wound healing due to the galvanotaxia phenomenon, in which fibroblasts in the dermis move toward the negative electrode in proportion to the voltage of the applied current.

[0046] By switching the polarity of the electrodes, current flows alternately from one direction (positive) to the opposite direction (negative) and vice versa, enabling uniform stimulation. In the case of alternating current or ultrasound, since energy vibrates, it only generates thermal energy by causing vibrations in cells or intercellular substances within skin tissues; it is difficult to stimulate cells or infectious agents, such as bacteria, in a consistent direction. However, direct current can stimulate cells or infectious agents in a consistent direction, and stimulation can also be applied in the opposite direction by changing the electrode orientation. This polarity switching makes wound healing more effective.

[0047] Then, an electrode patch according to another embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG. 7 is a schematic diagram illustrating an electrode patch according to another embodiment of the present invention, and FIG. 8 is a diagram showing another method of cutting the electrode patch illustrated in FIG. 7.

[0048] FIG. 7(a) is a small-sized electrode patch (200), the electrode patch (200) has first and second connecting electrodes (202, 203), first and second base electrodes, branch electrodes and an exudate absorbing member (204), and cut lines (201a, 201b) are indicated.

[0049] FIG. 7(b) is a medium-sized electrode patch (210), the electrode patch (210) has first and second connecting electrodes (212, 213), first and second base electrodes, branch electrodes and an exudate absorbing member (214), and cut lines (211a, 211b) are indicated.

[0050] FIG. 7(c) is a large-sized electrode patch (220), the electrode patch (220) has first and second connecting electrodes (222, 223), first and second base electrodes, branch electrodes and an exudate absorbing member (224), and cut lines (221a, 221b, 221c) are indicated.

[0051] The electrode patch (200) has 4 branch electrodes, the electrode patch (210) has 6 branch electrodes, and the electrode patch (220) has 7 branch electrodes. Since the distance between the branch electrodes of the electrode patches (200, 210, 220) is constant, the larger the number of branch electrodes, the larger the size. Each electrode patch (200, 210, 220) can be used by cutting along the perforation lines (201, 211, 221) according to the size of the wound. Since the electrode patches (200, 210, 220) are provided in large, medium, and small sizes, and each electrode patch can be used by cutting according to the size of the wound, any size of wound can be made into an appropriately sized electrode patch for use.

[0052] The electrode patches (200, 210, 220) have the same basic structure as the electrode patch (100) of the previous embodiment, except that their overall shape is elliptical and their size is different, so a detailed description is omitted.

[0053] The cutting line of the electrode patch (200, 210, 220) does not need to be limited to between the branch electrodes, and depending on the size of the wound or the patient's condition, the electrode patch can be cut horizontally or vertically as shown in FIG. 8. However, in this case, since electricity may not be supplied to the inner part as well as the outer part of the cut branch electrode, it is necessary to cut it to fit the size of the wound.

[0054] Then, with reference to FIGS. 9 and FIGS. 10, an electrode patch according to another embodiment of the present invention will be described in detail.

[0055] An electrode patch (300) according to another embodiment of the present invention includes a first electrode portion, a second electrode portion, an exudate absorption member (350), and an insulating member (340).

[0056] 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), and 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).

[0057] The first and second connecting electrodes (310, 320) are arranged in a vertical direction and have a connection portion at the bottom that can receive voltage from an external source.

[0058] The first base electrode (311) extends horizontally from the first connecting electrode (310) to the left and right, and at regular intervals, the first-1 to first-7 branch electrodes (312 to 318) branch off from the first base electrode (311) and extend vertically in a straight line.

[0059] The second base electrode (321) extends horizontally from the second connecting electrode (320) to the left and right, and at regular intervals, the 2-1 to 2-7 branch electrodes (322 to 328) branch off from the second base electrode (321) and extend vertically in a straight line.

[0060] In the first and second base electrodes (311, 321) and the branch electrode portions from which branching begins, the first electrode portion and the second electrode portion overlap, but an insulating member (340) is provided between them so that they are not electrically connected. The branch electrodes that are not overlapped outside the insulating member (340) are arranged alternately with a constant spacing from each other and become the portions placed over the wound area.

[0061] The first and second electrode parts and the insulating member (340) are attached to and fixed to the exudate absorption member (350).

[0062] Since the electrode patch (300) according to the embodiment of the present invention has a branch electrode in a straight line, it is sufficient to cut it in a straight line horizontally and vertically to a suitable size according to the size of the wound area, so there is no need to mark the cutting lines (331, 332, 333, 334). In addition, it does not matter if the electrode patch (300) is cut in a diagonal direction or a circular direction, even if it is not in the horizontal or vertical direction.

[0063] As shown in Fig. 10, it can be easily used by cutting it in the horizontal and vertical directions to fit the size of the wound (15), and electrical stimulation can be applied to the entire cut internal area.

[0064] FIG. 11 is a schematic diagram illustrating an electrode patch according to another embodiment of the present invention.

[0065] An electrode patch (400) according to another embodiment of the present invention illustrated in FIG. 11 includes a first electrode portion (410), a second electrode portion (420), an exudate absorption pad (440), a first insulating member (430), and a second insulating member (450).

[0066] The first and second electrode parts (410, 420) are substantially the same as those of the electrode patch (300) of the preceding embodiment, except that the number and size of the branch electrodes may differ, so a description thereof is omitted.

[0067] The first electrode part (410) is placed below the exudate absorption member (440), and the second electrode part (420) is placed above the first insulating member (430), so that the first insulating member (430) is positioned over the first electrode part (410). Then, the second insulating member (450) is attached over the second electrode part (420) of the combined assembly.

[0068] A plurality of holes (435) are drilled in the first insulating member (430), and the location of these holes is above the branch electrode of the first electrode part (410). Thus, the branch electrode of the first electrode part is exposed through these holes (435).

[0069] A plurality of holes (455) are also drilled in the second insulating member (450), and these holes (455) are drilled so as to overlap with the holes (435) of the first insulating member (430), so that the branch electrode of the first electrode part (410) is exposed through these holes (455). In addition, these holes (455) are drilled above the branch electrode of the second electrode part (420), so that the branch electrode of the second electrode part (420) is exposed through these holes (455). Unlike what is shown in FIG. 11, the shape, size, number, and arrangement relationship of the holes (435, 455) can be selected in various ways as needed.

[0070] Accordingly, the branch electrode of the first electrode part (410) and the branch electrode of the second electrode part (420) are exposed through the holes (435, 455) and cover the wound, and electrical stimulation can be applied through them. The unexposed parts are electrically blocked by the first and second insulating members (430, 450).

[0071] With the point electrode generated by such an electrode patch (400), an electric field can be efficiently generated while minimizing the aversion of patients sensitive to electricity.

[0072] The electrode patch (400) according to the embodiment of the present invention can also be cut relatively freely according to the size of the wound and the patient's condition, just like the electrode patch (300) of the previous embodiment.

[0073] Then, the results of an experiment conducted to demonstrate the therapeutic effect of the wound healing device according to an embodiment of the present invention will be explained with reference to FIGS. 12 to 14. FIG. 12 is a photograph of an experimental mouse for the present experiment, FIG. 13 is a table comparing the use of electric application and non-use according to an embodiment of the present invention, and FIG. 14 is an experimental photograph comparing the use of electric application and non-use according to an embodiment of the present invention.

[0074] Experiment

[0075] As shown in Fig. 12, two 8mm wounds were inflicted on experimental mice. The left wound was left as is, while the right wound was subjected to electrical stimulation according to an embodiment of the present invention for 15 minutes on weekdays for 5 days, for a total of 2 weeks. The electrical stimulation conditions were set as follows: voltage magnitude 130V, pulse duration 25μs, and pulse repetition count 1800 times * 2 times (Positive 1800 times, Negative 1800 times).

[0076] The size of the wound was measured daily as the wound healed, and after 7 days, the wound was sampled, cultured in a medium, and the number of bacteria (CFU) was observed.

[0077] As a result, as shown in Figure 13, the wound area is graphed in relation to wound recovery. The height of the right bar graph (black) with electric application according to the embodiment of the present invention is lower than the height of the left bar graph (green) with no electric application. This means that when electric application is applied, wound healing is faster and the size of the wound is reduced.

[0078] In addition, as shown in Figure 14, it was confirmed that the number of bacteria decreased significantly when electricity was applied (+ES) compared to when electricity was not applied (-ES).

[0079] As such, through experiments using actual laboratory mice, it can be confirmed that the wound healing device according to the embodiment of the present invention visibly reduces bacterial proliferation along with high skin regeneration of the wound.
