Description

Wound treatment electrode patch and wound treatment device using high-voltage pulse current electrical stimulation

[0001] The present invention relates to a wound treatment electrode patch and a wound treatment device using high voltage pulse current electrical stimulation.

[0002] Commonly used wound treatments include negative pressure wound therapy, hyperbaric oxygen therapy, debridement, and electrical / electromagnetic therapy. The most common method is negative pressure wound therapy, which applies negative pressure to a patient's wound, suctioning exudates such as blood and pus and promoting blood circulation to the wound site, thus promoting wound healing.

[0003] Meanwhile, as shown in Fig. 1, there is an electrical treatment method that helps wound healing by attaching electrodes (30, 40) to the skin around a wound (20) and allowing a device (50) to apply electricity to the electrodes (30, 40) to cause current to flow around the wound.

[0005] Republic of Korea Patent No. 10-1528401 (Published on June 5, 2015)

[0006] The problem to be solved by the present invention is to provide a wound treatment electrode patch and a wound treatment device that can improve the wound treatment effect by using high-voltage pulse current electrical stimulation.

[0007] According to one embodiment of the present invention for solving these problems, a wound treatment electrode patch comprises at least one first branch electrode, at least one second branch electrode, and an exudate absorbing member to which the first and second branch electrodes are attached and fixed, wherein the first branch electrode and the second branch electrode are arranged alternately and placed on a wound site.

[0008] There may be a penetration between the first branch electrode and the second branch electrode.

[0009] The size can be adjusted by cutting between the first branch electrode and the second branch electrode.

[0010] A cut line may be displayed to allow for resizing.

[0011] The shape of the first branch electrode and the second branch electrode may be any one of a circle, a semicircle, an oval, a semi-oval, a straight line, and a T-shape.

[0012] The first branch electrode may further include a first base electrode branched at regular intervals and a second base electrode branched at regular intervals, and an insulating member may be bonded between the first and second base electrodes.

[0013] According to another embodiment of the present invention, a wound treatment electrode patch comprises at least one first branch electrode, an exudate absorbing member coupled to the first branch electrode, at least one second branch electrode, a first insulating member positioned between the first branch electrode and the second branch electrode, and a second insulating member coupled to the second branch electrode, wherein the first branch electrode and the second branch electrode are arranged alternately, and a plurality of holes are formed in the first insulating member and the second insulating member.

[0014] According to another embodiment of the present invention, a wound treatment device includes at least one first branch electrode, at least one second branch electrode, and an exudate absorbing member to which the first and second branch electrodes are attached and fixed, wherein the first branch electrodes and the second branch electrodes are alternately arranged and include an electrode patch placed on a wound site, a vacuum pump that generates negative pressure to adhere the electrode patch to the wound site and suck up exudate from the wound, and a current applying device that causes current to flow through the first branch electrode and the second branch electrode.

[0015] The above current may be a high voltage pulsed current.

[0016] The direction of the current can be reversed by changing the polarity of the first branch electrode and the second branch electrode.

[0017] In this way, according to the wound treatment device according to the embodiment of the present invention, since the negative pressure treatment method and the electrical treatment method are combined, the efficiency of wound treatment is increased, and in particular, the wound treatment effect can be maximized by using a high-voltage pulse current.

[0018] In addition, according to the electrode patch for wound treatment according to an embodiment of the present invention, the electrode patch can be simply cut and used according to the size of the wound, so it can respond to wounds of any shape or size.

[0034] Therefore, it should be understood that 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, and that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0035] Hereinafter, with reference to the attached drawings, a wound treatment electrode patch and a wound treatment device according to an embodiment of the present invention will be described in detail so that a person having ordinary skill in the art to which the present invention pertains can easily practice the invention.

[0036] FIG. 2 is a schematic drawing of an electrode patch according to one embodiment of the present invention, and FIG. 3 is a drawing for explaining the electrode patch shown in FIG. 2 cut according to the size of a wound.

[0037] 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 absorbing member (140).

[0038] The first electrode section includes a first connection electrode (110), a first base electrode (111), a 1-1 branch electrode (112), a 1-2 branch electrode (113), a 1-3 branch electrode (114), a 1-4 branch electrode (115), and a 1-5 branch electrode (116), and the second electrode section includes a second connection electrode (120), a second base electrode (121), a 2-1 branch electrode (122), a 2-2 branch electrode (123), a 2-3 branch electrode (124), a 2-4 branch electrode (125), and a 2-5 branch electrode (126).

[0039] The first and second connecting electrodes (110, 120) are arranged vertically and have a connecting portion at the bottom that can receive voltage from the outside.

[0040] The first base electrode (111) extends horizontally to the left from the first connection electrode (110), and the 1-1 to 1-5 branch electrodes (112 to 116) branch off from the first base electrode (111) at regular intervals. The 1-2 to 1-5 branch electrodes (113 to 116) extend vertically from the first base electrode (111) and form an approximately semicircular or T-shaped shape. The 1-1 branch electrode (112) extends briefly in the column direction from the first connection electrode (110).

[0041] The second base electrode (121) extends horizontally to the right from the second connection electrode (120), and the 2-1 to 2-5 branch electrodes (122 to 126) branch from the second base electrode (121) at regular intervals. The 2-1 to 2-5 branch electrodes (122 to 126) extend in the column direction from the second base electrode (121) and form an approximately semicircular or T-shaped structure.

[0042] 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 arranged between the 1-1 branch electrode (112) and the 1-2 branch electrode (113), and the 2-2 branch electrode (123) is arranged between the 1-2 branch electrode (113) and the 1-3 branch electrode (114). Similarly, from the perspective of the second electrode section, the 1-2 branch electrode (113) is arranged between the 2-1 branch electrode (122) and the 2-2 branch electrode (123). The remaining branch electrodes are arranged in the same manner as illustrated in FIG. 2.

[0043] By being positioned in this manner, the first and second electrodes can densely cover the wound when placed over it, thereby enhancing the therapeutic effect. Unlike conventional electrode patches that are placed around the wound to provide electrical stimulation to the wound, the electrode patch (100) according to an embodiment of the present invention is placed directly over the wound to provide electrical stimulation to the wound. Therefore, the electrical stimulation can be directly applied to the wound, and is much more effective than stimulation provided from the surrounding area.

[0044] The first electrode portion and the second electrode portion are made of a thin film of a conductive material such as gold, silver, or platinum, and are attached and fixed to the exudate absorption member (140). The widths of these electrodes are almost the same, and the distance between adjacent electrodes is also almost the same.

[0045] The exudate absorbing member (140) absorbs exudate from the wound site, may be made of a hydrogel, and may be made of a breathable material to transmit negative pressure. In addition, the exudate absorbing member (140) supports the first and second electrode units and applies pressure from the rear to allow the first and second electrode units to adhere to the wound site.

[0046] Such electrode patches (100) can be manufactured as follows.

[0047] First, to form an electrode that directly contacts the wound, an electrode film is formed using materials such as platinum, gold, silver, or carbon on a polymer film such as PE or PET. At this time, the electrode film is formed using a deposition or plating method. After the electrode film is formed, the area outside the electrodes, including the area between the electrodes, is made into a through-hole structure so that negative pressure can be applied between the electrodes. The film with the electrode film is then attached to the exudate-absorbing material using a biocompatible double-sided tape or adhesive to form an integrated structure. If necessary, a cutting line is marked on the electrode or the exudate-absorbing material.

[0048] Meanwhile, the size of the electrode patch can be adjusted by cutting between the first and second base electrodes (111, 121) and the branch electrodes depending on the size of the wound area. For the convenience of cutting, a cutting line (130) can be marked on the first and second base electrodes (111, 121) and the exudate absorbing member (140). Since it is sufficient 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 cut along the cutting line (130) according to the wound size, the electrodes remaining inside, except for the cut outer electrodes, do not become disconnected.

[0049] FIG. 3(a) shows an electrode patch cut along a cutting line (130a) between a 1-2 branch electrode (113) and a 2-2 branch electrode (123) corresponding to the size of a wound (11), FIG. 3(b) shows an electrode patch cut along a cutting line (130b) between a 1-3 branch electrode (114) and a 2-3 branch electrode (124) corresponding to the size of a wound (12), FIG. 3(c) shows an electrode patch cut along a cutting line (130c) between a 1-4 branch electrode (115) and a 2-4 branch electrode (125) corresponding to the size of a wound (13), and FIG. 3(d) shows an electrode patch that is not cut corresponding to the size of a wound (14). Branch electrodes that can completely cover the wound but are of an appropriate size to apply current to the wound area are more effective in wound treatment.

[0050] In this way, according to the electrode patch (100) according to the embodiment of the present invention, it can be used by cutting it appropriately according to the size of the wound, so that it is possible to respond to wounds of various sizes with only one electrode patch.

[0051] Then, a wound treatment device according to an embodiment of the present invention that can help in wound treatment by providing electrical stimulation to a wound using such an electrode patch (100) will be described in detail with reference to FIGS. 4 to 6.

[0052] 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.

[0053] As illustrated in Fig. 4, a wound treatment device (500) according to one embodiment of the present invention includes an electrode patch (100), a main body (170), and a vacuum unit (180). The main body (170) includes a control device (171), a current applying device (175), a vacuum pump (172), a negative pressure sensor (174), and a negative pressure valve (173).

[0054] As shown in Fig. 5, the electrode patch (100) has a connecting portion (111, 121) at the end of the connecting electrode (110, 120) and is connected to a conductor (160) using a rivet or the like, and the end of the conductor (160) is connected to the main body (170) by a one-touch connector (165).

[0055] An electrode patch (100) is placed over a wound (10), with the electrode placed directly on the wound, and an exudate absorbing material (140) placed over the electrode. The fixing seal (150) is made of a film or the like that is used to fix the area around the wound (10) with an adhesive while the electrode patch (100) is placed over the wound (10) and to seal the area to maintain negative pressure on the wound (10).

[0056] The vacuum unit (180) transmits the vacuum pressure applied by the main body (170) to the inside of the fixed seal (150) so that negative pressure is maintained inside the fixed seal (150).

[0057] The vacuum pump (172) is a pump used to generate negative pressure in the wound area by extracting air from the wound area covered with the vacuum unit (180) and the electrode patch (100). The negative pressure valve (173) is a valve that adjusts the negative pressure generated in the wound area to become a reference negative pressure. The negative pressure sensor (174) detects negative pressure at the area where 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 in the waveform shown in FIG. 6 to the electrodes in the electrode patch (100). The control device (171) controls these to maintain an appropriate reference negative pressure in the wound area covered with the electrode patch (100) by using the pressure value received from the negative pressure sensor (174) to adjust the negative pressure valve (173), and instructs the current application device (175) to apply electricity so that direct current flows to 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 adheres the electrode patch (100) to the wound (10) area, so that electrical stimulation by the electrode can be effectively transmitted to the wound (10).

[0058] At this time, the electricity applied to the wound (10) is a high voltage pulsed current (HVPC) as a direct current. The electric waveform illustrated in Fig. 6 is an example, in which the voltage magnitude is 100 to 500 V, the time (A) for one pulse to last is 1 μs to 100 μs, the interval between pulses (B) is 100 ms to 10 sec, the time (C) for one polarity to last is 2.5 min to 30 min, the time (D) for the electrode to be changed is 200 μs to 1 ms, the time for one pulse bundle to last, that is, the time for performing one procedure, is 5 min to 60 min, and the interval between pulse bundles is 1 h to 12 h.

[0059] Electrical stimulation is known to aid in skin wound healing by acting in various ways at various stages, and is particularly effective when high voltages are used. High-voltage currents have excellent skin penetration, and due to the galvanotaxix phenomenon, in which fibroblasts in the dermis migrate toward the cathode in proportion to the applied current voltage, electrical stimulation using HVPC is significantly more effective in wound healing.

[0060] By reversing the polarity of the electrodes, the current can flow alternately from one direction (positive direction) to the opposite direction (negative direction) and vice versa, achieving a uniform stimulation. Since alternating current or ultrasound energy vibrates, it only generates heat energy by causing vibrations in cells or intercellular substances within the skin tissue, making it difficult to stimulate cells, bacteria, or other infectious agents in a consistent direction. However, direct current can stimulate cells or infectious agents in a consistent direction, and by reversing the electrode direction, it can also stimulate in the opposite direction. This polarity reversal makes wound healing more effective.

[0061] 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 drawing of an electrode patch according to another embodiment of the present invention, and FIG. 8 is a drawing showing another cutting method of the electrode patch illustrated in FIG. 7.

[0062] FIG. 7(a) shows a small-sized electrode patch (200), which has first and second connecting electrodes (202, 203), first and second base electrodes, branch electrodes, and an exudate absorbing member (204), and is indicated by cut lines (201a, 201b).

[0063] FIG. 7(b) shows a medium-sized electrode patch (210), which has first and second connecting electrodes (212, 213), first and second base electrodes, branch electrodes, and an exudate absorbing member (214), and is indicated by cut lines (211a, 211b).

[0064] FIG. 7(c) shows a large-sized electrode patch (220), which has first and second connecting electrodes (222, 223), first and second base electrodes, branch electrodes, and an exudate absorbing member (224), and has cut lines (221a, 221b, 221c) indicated thereon.

[0065] 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 cut along the cutting line (201, 211, 221) and used according to the wound size. Since the electrode patches (200, 210, 220) are provided in various sizes, large, medium, and small, and each electrode patch can be cut and used according to the wound size, an electrode patch of an appropriate size can be made and used for any wound.

[0066] 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 oval and their sizes are different, so a detailed description thereof is omitted.

[0067] The cutting line of the electrode patch (200, 210, 220) need not be limited to between the branch electrodes, and the electrode patch can be cut horizontally or vertically as shown in Fig. 8 depending on the size of the wound or the condition of the patient. However, in this case, electricity may not be supplied not only to the outer part of the cut branch electrode but also to the inner part, so it is necessary to cut it to fit the size of the wound.

[0068] Then, an electrode patch according to another embodiment of the present invention will be described in detail with reference to FIGS. 9 and 10.

[0069] An electrode patch (300) according to another embodiment of the present invention includes a first electrode portion, a second electrode portion, an exudate absorbing member (350), and an insulating member (340).

[0070] The first electrode section includes a first connection electrode (310), a first base electrode (311), a 1-1 branch electrode (312), a 1-2 branch electrode (313), a 1-3 branch electrode (314), a 1-4 branch electrode (315), a 1-5 branch electrode (316), a 1-6 branch electrode (317), and a 1-7 branch electrode (318), and the second electrode section includes a second connection electrode (320), a second base electrode (321), a 2-1 branch electrode (322), a 2-2 branch electrode (323), a 2-3 branch electrode (324), a 2-4 branch electrode (325), a 2-5 branch electrode (326), a 2-6 branch electrode (327), and a 2-7 branch electrode (328).

[0071] The first and second connecting electrodes (310, 320) are arranged vertically and have a connecting portion at the bottom that can receive voltage from the outside.

[0072] The first base electrode (311) extends horizontally from the first connection electrode (310) to the left and right, and the first-1 to first-7 branch electrodes (312 to 318) branch off from the first base electrode (311) at regular intervals and extend vertically in a straight line.

[0073] The second base electrode (321) extends horizontally from the second connection electrode (320) to the left and right, and the second-1 to second-7 branch electrodes (322 to 328) branch off from the second base electrode (321) at regular intervals and extend vertically in a straight line.

[0074] The first and second base electrodes (311, 321) and the branch electrode portions where the branches begin overlap each other, but an insulating member (340) is provided between them, so that they are not electrically connected. The branch electrodes that do not overlap outside the insulating member (340) are arranged alternately while maintaining a constant interval from each other, and become the portions placed over the wound area.

[0075] The first and second electrode parts and the insulating member (340) are attached and fixed to the exudate absorbing member (350).

[0076] The electrode patch (300) according to the embodiment of the present invention has a straight branch electrode, so it can be cut in a straight line horizontally and vertically to an appropriate size according to the size of the wound area, and therefore there is no need to mark cutting lines (331, 332, 333, 334). In addition, this electrode patch (300) may be cut diagonally or circularly, even if it is not in a horizontal or vertical direction.

[0077] As shown in Fig. 10, it can be conveniently used by cutting it in the horizontal and vertical directions appropriately to fit the size of the wound (15), and electrical stimulation can be provided to the entire cut internal area.

[0078] FIG. 11 is a schematic drawing of an electrode patch according to another embodiment of the present invention.

[0079] 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).

[0080] The first and second electrode portions (410, 420) are substantially the same as those of the electrode patch (300) of the previous embodiment, but the number and size of the branch electrodes may be different, so a description thereof is omitted.

[0081] The first electrode part (410) is coupled to the exudate absorbing member (440) and is placed below, and the second electrode part (420) is coupled to the first insulating member (430) and is placed above, with the first insulating member (430) being placed above the first electrode part (410). Then, the second insulating member (450) is coupled above the second electrode part (420) of the things coupled in this way.

[0082] The first insulating member (430) has a plurality of holes (435) formed therein, and the positions of these holes are 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).

[0083] A plurality of holes (455) are also formed in the second insulating member (450). These holes (455) overlap with the holes (435) of the first insulating member (430), so that the branch electrodes of the first electrode portion (410) are exposed through these holes (455). In addition, these holes (455) are formed above the branch electrodes of the second electrode portion (420), so that the branch electrodes of the second electrode portion (420) are exposed through these holes (455). Unlike what is illustrated in Fig. 11, the shape, size, number, and arrangement of the holes (435, 455) can be variously selected as needed.

[0084] 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 provided through them. The unexposed portion is electrically insulated by the first and second insulating members (430, 450).

[0085] By using point electrodes generated by electrode patches (400) like this, an electric field can be generated efficiently while minimizing the rejection of electrically sensitive patients.

[0086] The electrode patch (400) according to the embodiment of the present invention can also be cut and used relatively freely according to the size of the wound and the condition of the patient, like the electrode patch (300) of the previous embodiment.

[0087] Then, the results of an experiment conducted to prove the therapeutic effect of a wound treatment device according to an embodiment of the present invention will be described with reference to FIGS. 12 to 14. FIG. 12 is a photograph of an experimental mouse for this experiment, FIG. 13 is a table comparing the use and non-use of electrical application according to an embodiment of the present invention, and FIG. 14 is an experimental photograph comparing the use and non-use of electrical application according to an embodiment of the present invention.

[0088] Experiment

[0089] As shown in Fig. 12, two 8 mm wounds were applied to the experimental rat, and 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 each time for 5 weekdays, for a total of 2 weeks. The electrical stimulation conditions were as follows: voltage magnitude 130 V, pulse duration 25 μs, and pulse repetition number 1800 times x 2 times (Positive 1800 times, Negative 1800 times).

[0090] Wound size was measured daily according to wound healing, and after 7 days, the wounds were sampled, cultured on a medium, and the number of bacteria (CFU) was observed.

[0091] As a result, as shown in Fig. 13, the wound area is represented graphically in relation to wound recovery, and the height of the right bar graph (black) in which electricity was applied according to the embodiment of the present invention was lower than the height of the left bar graph (green) in which no electricity was applied, which means that when electricity was applied, wound healing was faster and the wound size was smaller.

[0092] Additionally, as shown in Figure 14, it was confirmed that the number of bacteria was significantly reduced in the case where electric power was applied (+ES) compared to the case where there was no electric power applied (-ES).

[0093] In this way, through experiments using actual laboratory mice, it can be confirmed that the wound treatment device according to the embodiment of the present invention not only achieves high skin regeneration of the wound but also visibly reduces bacterial proliferation.

[0094] The detailed description above is illustrative of the present invention. In addition, the above description merely illustrates and describes preferred embodiments of the present invention, and the present invention can be used in various other combinations, modifications, and environments.

Therefore, the detailed description of the invention above is not intended to limit the present invention to the disclosed embodiments. Furthermore, the appended claims should be construed to include other embodiments.
