Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a tumor electric field treatment device and an electrode patch. Background Art

[0002] Currently, the main treatments for tumors include surgery, radiotherapy, and chemotherapy, but all have corresponding disadvantages. For example, radiotherapy and chemotherapy can produce side effects and kill normal cells. Using electric fields to treat tumors is also one of the current research and development frontiers. Tumor electric field therapy is a tumor treatment method that uses a special electric field generator to generate a low-intensity, medium-high-frequency, alternating electric field to interfere with the mitotic process of tumor cells. Studies have shown that electric field therapy is effective in treating diseases such as glioblastoma, non-small cell lung cancer, and malignant pleural mesothelioma. The electric field applied by this treatment method can affect the aggregation of microtubules, prevent spindle formation, inhibit the mitotic process, and induce apoptosis in cancer cells.

[0003] The tumor electric field therapy device used to treat tumors mainly includes an electric field generator and an electrode sheet electrically connected to the electric field generator. The electrode sheet includes a transducer array capable of transmitting an alternating electric field. The transducer array includes a flexible circuit board, an insulating plate fixedly arranged on the side of the flexible circuit board facing away from the skin, and a dielectric element welded to the side of the flexible circuit board facing the skin. In order to better achieve the treatment effect, it is necessary to place the electrode sheet on the skin surface corresponding to the patient's tumor site for a long time to perform alternating electric field tumor treatment. When the alternating electric field is applied to the patient's tumor site through the electrode sheet for a long time for tumor treatment, heat will accumulate on the skin surface, causing sweating and producing water vapor. If the water vapor cannot be discharged in time, it will cause blockage of the sweat glands and hair follicles on the outside of the skin, thereby causing skin erythema, itching, inflammation of the hair follicles, pain, papules and other skin discomfort symptoms.

[0004] Therefore, it is necessary to provide an improved tumor electric field treatment device and electrode patch to overcome the problems existing in the prior art. Utility Model Content

[0049] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of devices, systems, apparatus, and methods consistent with certain aspects of the present application.

[0050] The present application provides embodiments of various electrode patches for a tumor electric field therapy device for tumor electric field therapy, wherein each electrode patch is provided with a flexible circuit board, multiple dielectric elements or dielectric layers arranged on the flexible circuit board, and a conductive gel covering the dielectric elements or dielectric layers. Each embodiment of the electrode patch is described below.

[0051] First embodiment of the electrode patch

[0052] Figures 1 to 10 Shown is the electrode patch 100 of this embodiment.

[0053] refer to Figures 1 to 5 As shown, electrode patch 100 includes an electrical component 11, a backing 12, several supporting members 13, wires 14 electrically connected to electrical component 11, and several adhesive members 15. Electrical component 11 is adhered to backing 12, and supporting members 13 are adhered to backing 12 in a manner that surrounds electrical component 11. Adhesive members 15 cover corresponding portions of electrical component 11 and supporting members 13. Electrode patch 100 is attached to the patient's body surface corresponding to the tumor site via backing 12. Electrical component 11 applies an alternating electric field to the tumor site to disrupt or prevent mitosis in the patient's tumor cells, thereby achieving the purpose of tumor treatment.

[0054] The electrical functional component 11 includes a plurality of electrode units 110 arranged in an array, a plurality of connecting portions 1112 connecting two adjacent electrode units 110, and a wiring portion 1113 extending laterally from a connecting portion 1112. The electrode units 110 are generally circular sheet-shaped. The connecting portion 1112 includes a first connecting portion 11120 connecting two adjacent electrode units 110 in the same column and a second connecting portion 11121 connecting two adjacent electrode units 110 in the same row. The length of the first connecting portion 11120 is less than the length of the second connecting portion 11121. The wiring portion 1113 is located between two adjacent columns of electrode units 110 and extends laterally from a second connecting portion 11121 away from the electrical functional component 11 to connect to the wire 14. The wiring portion 1113 is arranged perpendicular to the second connecting portion 11121 and is arranged approximately parallel to the first connecting portion 11120. The connection portion 1113 and the adjacent electrode unit 110 are arranged in an interval shape, which can provide a larger operating space for welding between the connection portion 1113 and the wire 14 .

[0055] The backing 12 is provided in a sheet shape and is mainly made of a flexible and breathable insulating material. The backing 12 is a mesh fabric. Specifically, the backing 12 is a mesh non-woven fabric, which has the characteristics of being soft, light, moisture-proof, and breathable. When applied to the patient's body surface for a long time, it can still keep the patient's skin surface dry. A biocompatible adhesive (not shown) is also coated on the side of the backing 12 facing the patient's body surface for closely adhering the backing 12 to the body surface corresponding to the patient's tumor site. In this embodiment, the backing 12 is generally provided in a rectangular sheet shape. The edge of the backing 12 is provided in a concave-convex shape. The backing 12 has two notches 121 recessed inward from the center of its long side. The notches 121 are aligned with the upper edge of the patient's external auditory meatus bone during application. The backing 12 also has a plurality of wings 122 extending outward from its peripheral side for an operator to hold to apply the electrode patch 100 to the body surface corresponding to the patient's tumor site. The backing 12 also has concave corners 123 recessed inward from its four corners to prevent wrinkles from forming when the backing 12 is applied to the body surface corresponding to the tumor site.

[0056] The support member 13 is adhered to the backing 12. A through hole 130 for accommodating the electrode unit 110 is provided through the middle of the support member 13. The dielectric elements 113 of the electrode units 110 in the same column can be surrounded by the same support member 13. The support member 13 can be made of a foam material to ensure the air permeability requirement of the electrode patch 100. In this embodiment, there are three support members 13, which are arranged in a side-by-side and spaced manner and respectively surround the dielectric elements 113 of the electrode units 110 in different columns. The support member 13 is flush with the surface of the electrode unit 110 on the side away from the backing 12. That is, the support member 13 is flush with the surface of the electrode unit 110 facing the adhesive member 15.

[0057] The adhesive member 15 has double-sided adhesiveness. One side of the adhesive member 15 is adhered to the surface of the support member 13 and the electrode unit 110 on the side away from the backing 12. The other side of the adhesive member 15 serves as an application layer, which is applied to the human body surface skin to keep the skin surface moist and relieve local pressure. The adhesive member 15 can preferably adopt a conductive adhesive member to act as a conductive medium. Under the support of the support member 13, the adhesive member 15 has better adhesiveness to the human skin.

[0058] In this embodiment, the electrical functional component 11 of the electrode patch 100 includes 9 electrode units arranged at intervals, which are arranged in a three-row and three-column matrix and form a roughly "king" shape through the connecting portion 1112. Figure 6As shown, the first connection portion 11120 of the connection portion 1112 connects all two adjacent electrode units 110 arranged in a column, and the second connection portion 11121 of the connection portion 1112 connects at least two adjacent electrode units 110 arranged in a row. There is at least one second connection portion 11121 between the electrode units 110 in adjacent columns to achieve electrical connection between the electrode units 110 arranged in each column. All second connection portions 11121 located between two electrode units 110 arranged in a row can be second connection portions 11121 that achieve electrical connection between the two adjacent electrode units 110, or can include second connection portions 11121 that partially achieve electrical connection between the two adjacent electrode units 110 and second connection portions 11121 that only achieve fixed connection but not electrical connection between the two electrode units 110.

[0059] In this embodiment, the wiring portion 1113 is welded to the wire 14 to achieve electrical connection between the electrical functional component 11 and the wire 14. A row of gold fingers 11130 welded to the wire 14 are staggered on the two side surfaces of the wiring portion 1113 away from one end of the second connection portion 11121. The welding point between the wire 14 and the gold fingers 11130 of the wiring portion 1113 is covered with a heat shrink tubing 141. The heat shrink tubing 141 insulates and protects the connection between the wire 14 and the wiring portion 1113 of the electrical functional component 11, and provides support to prevent the connection between the wire 14 and the wiring portion 1113 of the electrical functional component 11 from breaking, while also being dustproof and waterproof. The end of the wire 14 away from the second connection portion 11121 is provided with a plug 142 electrically connected to an electric field generator (not shown). One end of the wire 14 is electrically connected to the gold finger 11130 of the connection portion 1113 ; the other end is electrically connected to the electric field generator (not shown) through the plug 142 to provide the electrode patch 100 with an alternating current signal for tumor treatment during tumor electric field therapy.

[0060] refer to Figures 6 to 10 As shown, the specific structure of the electrode unit 110 is described in detail below. The electrode unit 110 includes a main body 1111 provided at two opposite ends of the connecting portion 1112, an insulating plate 112 provided on the side of the main body 1111 away from the human skin, a dielectric element 113 provided on the side of the main body 1111 facing the human skin, and a temperature sensor 114 optionally provided on the main body 1111 and located on the same side as the dielectric element 113. The main body 1111, the insulating plate 112, and the dielectric element 113 are all circular sheet-shaped structures. The insulating plate 112, the main body 1111, and the dielectric element 113 are provided in a one-to-one correspondence, and the centers of the three are located on the same straight line. In other embodiments, the main body 1111 can also be a strip-shaped structure extending from the end of the connecting portion 1112.

[0061] The main body 1111, insulating plate 112, and dielectric element 113 are all arranged in three rows and three columns. The main body 1111 of the electrode unit 110 arranged in three rows and three columns, the multiple connecting portions 1112 located between two adjacent electrode units 110, and the wiring portion 1113 extending outward from a connecting portion 1112 collectively constitute the flexible circuit board 111 of the electrical functional component 11. From the perspective of the formation of the electrode unit 110, the insulating plate 112 is arranged on the side of the main body 1111 of the flexible circuit board 111 away from the human skin, the dielectric element 113 is arranged on the side of the main body 1111 of the flexible circuit board 111 facing the human skin, and the temperature sensor 114 is optionally arranged on the side of the main body 1111 of the flexible circuit board 111 facing the human skin. The insulating plate 112 and the dielectric element 113 are respectively arranged on opposite sides of the main body 1111 of the flexible circuit board 111. The main body 1111 of the flexible printed circuit board 111 of the electrical functional component 11 is arranged in accordance with the arrangement of the electrode unit 110 of the electrical functional component 11 .

[0062] A conductive plate 1114 is provided on the side of the main body 1111 facing the dielectric element 113. The conductive plate 1114 of the main body 1111 can be completely covered by the dielectric element 113, so that the conductive plate 1114 and the dielectric element 113 can be soldered together by solder 115. The conductive plate 1114 of the main body 1111 includes a plurality of conductive cores 11140 arranged in a centrally symmetrical shape, which can effectively prevent the position of the dielectric element 113 from being shifted due to the stacking of solder 115 during the soldering process. The center of the conductive plate 1114 of the main body 1111 is located on the center line of the main body 1111. The top surfaces of the plurality of conductive cores 11140 of the conductive plate 1114 are located in the same plane, which can avoid the occurrence of cold solder joints with the dielectric element 113 during soldering. The center of the conductive plate 1114 is also located on the center line of the dielectric element 113.

[0063] In this embodiment, the conductive plate 1114 of the same main body 1111 includes four conductive cores 11140 spaced apart and arranged in a centrally symmetrical pattern. The multi-point spacing of the conductive cores 11140 in the conductive plate 1114 reduces the amount of copper foil used to manufacture the conductive cores 11140, thereby lowering material costs. It also reduces the amount of solder 115 used to bond the conductive cores 11140 to the dielectric element 113, further reducing material costs.

[0064] The four conductive cores 11140 of the same conductive disk 1114 all have a petal-shaped structure. Each conductive core 11140 includes an inner arc (unnumbered) and an outer arc (unnumbered) connected end to end. The inner arc (unnumbered) and outer arc (unnumbered) of the conductive core 11140 are arranged axially symmetrically. The inner arc (unnumbered) of each of the four conductive cores 11140 of the same conductive disk 1114 is concave toward the center of the conductive disk 1114. The outer arc (unnumbered) of each of the four conductive cores 11140 of the same conductive disk 1114 is convex away from the center of the conductive disk 1114. The multiple conductive cores 11140 that comprise the conductive disk 1114 are arranged both centrally and axially symmetrically, with each conductive core 11140 also arranged axially symmetrically. This ensures stress balance at each weld point when welding the multiple conductive cores 11140 of the conductive disk 1114 of the main body 1111 to the dielectric element 113, ensuring overall weld balance for the dielectric element 113 and improving weld quality. This prevents imbalanced welding stress from causing tilting of the dielectric element 113, which could weaken and easily break the weld on the side with a larger gap between the dielectric element 113 and the main body 1111. This also prevents impacting the fit of the electrode patch 100. The outer arcs (unnumbered) of the multiple conductive cores 11140 of the same conductive disk 1114 are generally located on the same circumference.

[0065] The insulating plate 112 is made of an insulating material. Preferably, the insulating plate 112 is an epoxy glass cloth laminate. The insulating plate 112 is adhered to the side of the main body 1111 away from the human skin through a sealant (not shown), which can enhance the strength of the main body 1111, provide a flat welding plane for the welding operation between the main body 1111 and the dielectric element 113, and improve the product yield. At the same time, the insulating plate 112 can also isolate the water vapor in the air on the side of the electrode patch 100 away from the skin from contacting the solder 115 located between the main body 1111 and the dielectric element 113, thereby preventing water vapor from corroding the solder 115 between the main body 1111 and the dielectric element 113 and affecting the electrical connection between the main body 1111 and the dielectric element 113.

[0066] The size of the insulating plate 112 is the same as that of the main body 1111 to prevent the sealant (not shown) from creeping to the side of the main body 1111 facing the human skin due to the capillary effect when the insulating plate 112 is adhered to the side of the main body 1111 away from the human skin through the sealant (not shown), thereby affecting the filling of the sealant 117 in the gap 116 formed by welding the dielectric element 113 and the main body 1111, resulting in voids in the sealant 117, thereby preventing the sealant 117 from rapidly expanding during high-temperature curing due to the large difference in thermal expansion coefficient between the water vapor in the void and the sealant 117, causing bursting and popcorn phenomenon, thereby damaging the product.

[0067] The dielectric element 113 is made of a high dielectric constant material or a high molecular polymer with dielectric properties. It has the conductive property of hindering the conduction of direct current and allowing alternating current to pass through, which can ensure the safety of the human body. Preferably, the dielectric element 113 is a dielectric ceramic sheet with a dielectric constant of at least greater than 1000. The dielectric element 113 has an annular structure, and a through-hole 1131 is provided in the middle thereof for accommodating the temperature sensor 114. A ring-shaped metal layer 1132 is attached to the side of the dielectric element 113 facing the main body 1111. A point-to-face welding is formed between the metal layer 1132 of the dielectric element 113 and the conductive core 11140 of the conductive disk 1114 of the main body 1111, which does not require high welding alignment accuracy and is more convenient. The gap 116 formed by welding the dielectric element 113 to the main body 1111 is filled with a sealant 117 to protect the solder 115 between the dielectric element 113 and the main body 1111, preventing the dielectric element 113 from being affected by external forces and causing the weld to break, thereby preventing the alternating electric field from being applied to the patient's tumor site through the dielectric element 113; at the same time, it can also prevent water vapor in the air from entering the gap 116 and corroding the solder 115 between the dielectric element 113 and the main body 1111, thereby affecting the electrical connection between the dielectric element 113 and the main body 1111.

[0068] The inner ring of the metal layer 1132 of the dielectric element 113 is spaced from the edge of the through-hole 1131 of the dielectric element 113. This prevents the solder 115 between the metal layer 1132 of the dielectric element 113 and the main body 1111 from spreading toward the through-hole 1131 of the dielectric element 113 when heated and melted, potentially shorting the temperature sensor 114. The outer ring of the metal layer 1132 of the dielectric element 113 is also spaced from the outer edge of the dielectric element 113. This prevents the solder 115 between the metal layer 1132 of the dielectric element 113 and the main body 1111 from overflowing outside the main body 1111 when heated and melted, potentially allowing direct current to pass through unimpeded by the dielectric element 113 and act on the patient's body surface when the electrode patch 100 is applied to the tumor site.

[0069] The outer diameter of dielectric element 113 is slightly smaller than the diameter of main body 1111. This allows sealant 117 to flow along the edge of main body 1111 outside dielectric element 113 and into gap 116 through a capillary effect when filling with sealant 117. This facilitates the filling of sealant 117 within gap 116 formed by welding dielectric element 113 to main body 1111. When sealant 117 is filled into gap 116 formed by welding dielectric element 113 to main body 1111, air within gap 116 can be discharged through perforations 1131 of dielectric element 113, preventing the formation of voids in sealant 117 within gap 116 and improving product quality. Sealant 117 is sealed twice. First, the sealant is filled from the edge of dielectric element 113 into gap 116 between dielectric element 13 and main body 1111. Solder 115 is applied in dots. Sealant 117 flows inward through the gap between solder 115 and covers solder 115. After high-temperature curing, a second sealing is performed. The second sealing is performed by filling sealant 117 into through-hole 1131 of dielectric element 13 to fully seal temperature sensor 114.

[0070] There are multiple temperature sensors 114, each housed within a corresponding through-hole 1131 of the dielectric element 113. In this embodiment, there are eight temperature sensors 114, located on each of the eight electrode units 110, excluding the electrode unit 110 in the middle of the middle row. The eight temperature sensors 114 are each located at the center of the main body 1111 of the corresponding electrode unit 110. The temperature sensors 114 are used to monitor the temperature of the adhesive member 15 on the side of the dielectric element 113 covering the electrical functional component 11 that faces the human skin, and further detect the temperature of the human skin to which the adhesive member 15 is attached. When the temperature detected by the temperature sensor 114 exceeds the upper limit of the human body's safe temperature, the tumor electric field therapy device can promptly reduce or shut off the alternating current transmitted to the electrode patch 100 to prevent low-temperature burns. The temperature sensor 114 is welded to the main body 1111 and then sealed with sealant 117 to prevent moisture from corroding the temperature sensor 114 and causing it to fail. The temperature sensor 114 has a signal terminal (not shown) and a ground terminal (not shown). In this embodiment, the temperature sensor 114 is preferably a thermistor. In other embodiments, the specific number of the temperature sensors 114 can be set as needed.

[0071] Please refer to Figure 9 and Figure 10As shown, the conductive traces L of the flexible printed circuit board 111 are layered and embedded within its insulating substrate B. These traces include a first conductive trace L1 that connects in series the conductive cores 11140 of all conductive pads 1114 located on the main body 1111; a second conductive trace L2 that connects in series the ground terminals (not shown) of all thermistors 114 located on the main body 1111; and a third conductive trace L3 that connects in parallel the signal terminals (not shown) of all thermistors 114 located on the main body 1111. In this embodiment, the first conductive trace L1 provides a single path connecting in series all the conductive cores 11140 of the conductive pads 1114 located on each main body 1111 and electrically connecting to corresponding gold fingers 11130 exposed from the insulating substrate B on the connection portion 1113. The second conductive trace L2 provides a single path connecting in series the ground terminals (not shown) of each thermistor 114 located on each main body 1111. The third conductive trace L3 has multiple paths, each connected to a signal terminal (not shown) of each thermistor 114 located on each main body portion 1111, and connects the signal terminals (not shown) of each thermistor 114 located on each main body portion 1111 in parallel. Specifically, the third conductive trace L3 has eight paths, the same number as the thermistors 14. The first conductive trace L1, the second conductive trace L2, and the third conductive trace L3 are each electrically connected to a corresponding gold finger 11130 of the connection portion 1113.

[0072] From the perspective of the wiring of the conductive traces L, they are arranged in two layers within the insulating substrate B of the flexible circuit board 11. The layer closest to the patient's skin is defined as the first layer, and the layer further from the patient's skin is defined as the second layer. The portion between the first and second layers, connecting the corresponding portions of the conductive traces on the first layer to the corresponding portions on the second layer, is defined as the conductive layer. The first conductive trace L1, which connects the conductive cores 11140 of all conductive plates 1114 in series, is located in the first layer and surrounds the second conductive trace L2. The portion of the second conductive trace L2 that connects to the ground terminal (not shown) of the thermistor 114 is located in the first layer. The portion of the second conductive trace L2 that connects to the corresponding gold fingers 11130 of the connection portion 1113 is also located in the first layer. The second conductive trace L2 first connects the portion connected to the ground terminal (not shown) of the thermistor 114 to the corresponding portion on the second layer through a corresponding conductive layer, and then connects the corresponding portion on the second layer to the portion on the first layer and connected to the corresponding gold finger 11130 of the wiring portion 1113 through another corresponding conductive layer, thereby bypassing the first conductive trace L1 surrounding the corresponding portion on the first layer to avoid crossing the first conductive trace L1.

[0073] Each third conductive trace L3 connected to the signal terminal (not shown) of the thermistor 114 includes a portion located on the second layer and electrically connected to the corresponding gold finger 11130 of the connection portion 1113, a portion located on the first layer and connected to the signal terminal (not shown) of the thermistor 114, and a conductive layer connecting the first-layer portion with the second-layer portion. The portion of the second conductive trace L2 located on the second layer is positioned between corresponding portions of multiple third conductive traces L3 on the same layer. The corresponding portion of the second conductive trace L2 located on the second layer is positioned near the connection portion 1113, with three third conductive traces L3 arranged on one side and five third conductive traces L3 arranged on the other side.

[0074] The following combination Figure 5 and Figure 9 The size parameters of the electrode patch 100 are introduced as shown.

[0075] In order to prevent the electrical functional components 11 from overlapping and affecting the treatment effect after the electrode patch 100 is applied to the head, the maximum size of the electrical functional component 11 is based on the average head size of the sampling statistics, which can be suitable for most patients. Ignoring the size of the wiring portion 1113 extending outside the array where the electrode unit 110 is located, all electrode units 110 of the electrical functional component 11 are spaced apart in an area with a maximum of 170mm×100mm and a minimum of 79mm×65mm. The diameter of the electrode unit 110 is at least 21mm. Preferably, the diameter of the electrode unit 110 is 21-22mm, which can take into account the effect of tumor electric field therapy and the adhesion between the electrode patch 100 and the patient's skin. The column spacing of the electrical functional component 11 is at least 1mm and a maximum of 53.5mm; the row spacing is at least 1mm and a maximum of 18.5mm.

[0076] In this embodiment, the row spacing of the electrical functional component 11 is 1.5 mm, and the column spacing is 24 mm. The diameter of the electrode unit 110 is 21 mm. Ignoring the dimension of the wiring portion 1113 extending outside the array where the electrode unit 110 is located, the length of the area where the electrical functional component 11 is located is 111 mm and the width is 66 mm. The length of the connecting portion 1112 is close to the spacing between the two electrode units 110 connected to it. There will be a certain amount of overlap in the length dimension of the connecting portion 1112 and the edge connection of the electrode unit 110, so the length dimension of the connecting portion 1112 is slightly larger than the spacing between the two electrode units 110 connected to it. The length of the first connecting portion 11120 is approximately 24.7 mm, and the length of the second connecting portion 11121 is approximately 2.1 mm.

[0077] The electrical functional component 11 has nine electrode units 110 arranged in a matrix of three rows and three columns, each of which has a first open space 118 between the electrode units 110. This allows the skin on the patient's tumor site, which is covered by the electrode patch 100, to breathe freely after the electrode patch 100 is placed on the patient's tumor site. In this embodiment, there are four first open spaces 118 in the electrical functional component 11, each located within an area enclosed by four electrode units 110 in adjacent columns and rows. The width of the connecting portion 1112 is 4.5-6 mm, which can be determined based on wiring requirements and manufacturing costs, such as ensuring sufficient first open spaces 118 between the electrode units 110 to facilitate heat and water vapor dissipation. Preferably, the width of the connecting portion 1112 is 4.5 mm, so that the wiring design is sufficient and there is a first open space 118 of sufficient area between the electrode units 110 to facilitate heat and water vapor dissipation.

[0078] The wiring portion 1113 is extended laterally from the connecting portion 1112 and is partially located in one of the first open spaces 118 to shorten the distance that the wiring portion 1113 exceeds the edge of the electrical functional component 11, so that the electrical functional component 11 is arranged more compactly, and the manufacturing cost is increased by increasing the overall size of the electrical functional component 11. The width of the wiring portion 1113 is at least 4 mm. Preferably, the width of the wiring portion 1113 is 4-8 mm. The width of the wiring portion 1113 is 8 mm, and the distance from the edge of the main body 111 on both sides thereof is 8 mm each, so as to provide sufficient wiring space and reduce the difficulty of manufacturing. The maximum available ventilation area of the first open space 118 for the wiring portion 1113 to pass through is approximately 2809 mm 2 , the minimum area is about 196mm 2 The maximum area of each of the remaining three first open spaces 118 is approximately 3000 mm 2 The minimum area is about 314mm 2 The distance between the connection portion 1113 and the adjacent electrode units 110 is at least 2 mm. That is, the distance between the two columns of electrode units 110 on both sides of the connection portion 1113 is at least 8 mm.

[0079] The support member 13 is a rectangular sheet with rounded corners and a through hole 130 in the middle. It is arranged around the three dielectric elements 113 in the same row. The side of the support member 13 facing away from the patient's skin is directly adhered to the backing 12, and the portion located between two adjacent rows of dielectric elements 113 extends into the first open space 118. The adhesive member 15 is a rectangular sheet with rounded corners and covers the support member 13 as a whole. The length and width of the adhesive member 15 are slightly larger than those of the support member 13. The portion of the adhesive member 15 that is larger than the support member 13 just covers the side of the support member 13. That is, the adhesive member 15 has a portion that corresponds to the through hole 130 of the support member 13 and directly covers the side of the dielectric element 113 facing the patient's skin, a portion that covers the side of the support member 13 facing the patient's skin, and a portion that covers the side of the support member 13 in the thickness direction. The adhesive member 15 covers the support member 13, and the portion thereof located between two adjacent rows of dielectric elements 113 also extends into the first open space 118. That is, the portion of the adhesive member 15 covering the side of the support member 13 facing the patient's skin and located between two adjacent rows of dielectric elements 113 will occupy a portion of the first open space 118. The portion of the first open space 118 occupied by the adhesive member 15 is the second open space 119. The size of the second open space 119 is slightly smaller than that of the first open space 118, and the portion thereof that is smaller than the corresponding first open space 118 is covered by the adhesive member 15. The second open space 119 is formed by enclosing two adjacent adhesive members 15 and the second connecting portion 11121 of the flexible circuit board 111, allowing the patient's skin to breathe freely and dissipate heat. Since the adhesive 15 has low air permeability, it will affect the efficient air permeability area of the first open space 118. Therefore, when designing the size, the adhesive 15 will be designed to be as narrow as possible under the premise that it can completely cover the part of the support 13 facing the patient's skin and the side of the support 13 along its thickness direction. Similarly, since the adhesive 15 needs to be larger than the length of the support 13, the support 13 also needs to be designed to be as narrow as possible under the premise of providing good support for the adhesive 15, so as to ensure that the area of the second open space 119 that allows the skin to penetrate moisture in the first open space 118 is as large as possible. The following dimensional design approach is recommended: the width of the support member 13 is 1-8 mm larger than the diameter of the dielectric element 113, preferably 5 mm larger. That is, the distance a single support member 13 extends into the first open space 118 along its width is 0.5-4 mm, and the distance two adjacent support members 13 extend into the first open space 118 along the width is 1-8 mm. The flat width of the adhesive member 15 is 2-14 mm larger than the width of the support member 13. Considering that the edge of the adhesive member 15 covers the side end surface of the support member 13 (with a thickness of 1 mm), the width of the adhesive member 15 after covering the support member 13 is 0-12 mm larger than the width of the support member 13. In other words, the distance that the adhesive member 15 extends into the first open space 118 along its width is 0.5-10 mm.

[0080] In this embodiment, the diameter of the dielectric element 113 is 20 mm, the width of the support member 13 is 25 mm, the thickness of the support member 13 is 1 mm, and the width of the adhesive member 15 is 27-29 mm. The length of the adhesive member 15 is slightly longer than the length of the support member 13, which is slightly longer than the total length of the plurality of dielectric elements 113 in a row, without specific limitations. While ensuring their respective functions, the support member 13 and the adhesive member 15 are designed to be as narrow as possible to maximize the area of the second open space 119 to be close to the area of the first open space 118, thereby maximizing the moisture permeability of the first open space 118. It can be understood that the plurality of adhesive members 15 spaced apart form a plurality of the aforementioned second open spaces 119, and the size of the second open spaces 119 is smaller than the size of the first open spaces 118. In this embodiment, the row spacing between two adjacent dielectric elements 113 is 25 mm, the spacing between two adjacent support members 13 is 20 mm, and the spacing between two adjacent adhesive members 15 is 18 mm.

[0081] When the electrode patch 100 is in use, the first open space 118 can conduct heat and evaporate moisture to the skin surface. The backing 12 is made of breathable material and has almost no effect on breathability. Most of the first open space 118 is ventilated and dissipated outward through the completely open second open space 119. The part of the first open space 118 covered by the support 13 and the adhesive 15 absorbs moisture through the support 13 and the adhesive 15. During the tumor electric field therapy process, the heat accumulated on the skin surface corresponding to the patient's electrode patch 100 and the water vapor generated by sweating can be discharged into the outside air through the second open space 119, avoiding skin erythema, itching, and follicular inflammation, pain, papules and other skin discomfort symptoms.

[0082] Second embodiment of the electrode patch

[0083] Figures 11 to 14 Shown is the electrode patch 200 of this embodiment.

[0084] refer to Figures 11 to 12 As shown, the electrode patch 200 includes a backing 22, an electrical component 21 adhered to the backing 22, a plurality of supports 23 adhered to the backing 22 in a manner surrounding the electrical component 21, a wire 24 electrically connected to the electrical component 21, and a plurality of adhesive members 25 covering corresponding portions of the electrical component 21 and the supports 23. The electrode patch 200 is attached to the patient's body surface corresponding to the tumor site via the backing 22. The electrical component 21 applies an alternating electric field to the patient's tumor site to disrupt or prevent mitosis of the patient's tumor cells, thereby achieving the purpose of tumor treatment.

[0085] The electrical functional assembly 21 includes a flexible printed circuit board 211 having several main bodies 2111, a plurality of insulating plates 212 and dielectric elements 213 disposed on opposite sides of the main bodies 2111, and a plurality of temperature sensors 214 optionally affixed to the main bodies 2111. The main bodies 2111, the corresponding insulating plates 212, the corresponding dielectric elements 213, and the optionally provided temperature sensors 214 form electrode units 210, which are arranged in an array. The flexible printed circuit board 211 also includes a plurality of connecting portions 2112 for connecting to the electrode units 210, and a wiring portion 2113 extending laterally from a connecting portion 2112 and electrically connected to the conductive wire 24. In this embodiment, the electrode patch 200 is provided with 13 electrode units, which increases the coverage area of the electrode patch 200, enhances the electric field strength applied to the tumor site for tumor electric field therapy, and increases the range of the alternating electric field covering the tumor site, thereby improving the therapeutic effect.

[0086] The structure of the electrode unit 210 is the same as that of the electrode unit 110 of the electrode patch 100 in the first embodiment. For related content, please refer to the relevant content of the electrode patch 100 in the first embodiment and will not be repeated here. The main difference between the electrode patch 200 in this embodiment and the electrode patch 100 in the first embodiment is the different number and arrangement of the electrode units 210, as well as some adjustments made due to the different number and arrangement of the electrode units 210, including the arrangement, row spacing, column spacing, the setting of the connection portion, the setting of the wiring portion, and various dimensions, etc. The following will focus on these differences. For other content, please refer to the relevant content of the electrode patch 100 in the first embodiment.

[0087] In this embodiment, the electrode units 210 are distributed in a matrix area of five rows and five columns, and the arrangement of the main body 2111 is consistent with the arrangement of the electrode units 210. The arrangement of the main body 2111 will be described below. From the perspective of row arrangement, the first and last rows are each provided with two main body 2111, and each of the three middle rows is provided with three main body 2111. In this embodiment, the main body 2111 is distributed in an array area of five rows and five columns. From the perspective of column arrangement, the first, third, and fifth columns are each provided with three main body 2111, and the second and fourth columns are each provided with two main body 2111. Specifically, the two main body 2111 of the first row are respectively located in the second and fourth columns, the three main body 2111 of each of the three middle rows are respectively located in the first, third, and fifth columns, and the two main body 2111 of the last row are respectively located in the second and fourth columns. The two adjacent main bodies 2111 in each row are arranged in alternate columns, and the main bodies 2111 in the second and fourth columns are arranged in alternate rows. The two adjacent main bodies 2111 in the first, third and fifth columns are arranged in adjacent rows. The spacing between the two adjacent main bodies 2111 in the same row is equal. The spacing between the two adjacent main bodies 2111 in the same column is equal. The two main bodies 2111 in the last row are arranged in a disconnected manner, forming a gap 2C between the two main bodies 2111. The wiring portion 2113 is extended laterally from the main body 2111 in the third column of the fourth row. The wiring portion 2113 passes through the gap 2C formed between the two main bodies 2111 in the last row.

[0088] All main bodies 2111 of the flexible circuit board 211 are arranged at intervals within an area with a minimum length of 109 mm and a minimum width of 109 mm. The diameter of the main body 2111 is 21 mm. The spacing between two adjacent main bodies 2111 in each row is the same, at least 23 mm. The spacing between two adjacent main bodies 2111 in the second column and each of the fourth columns is the same, at least 67 mm. The spacing between two adjacent main bodies 2111 in each of the first column, the third column, and the fifth column is the same, at least 1 mm. The aforementioned electrode patch 200 with the minimum-sized main body 2111 is suitable for use by children of smaller size.

[0089] To prevent overlap of the electrical components 21 after the electrode patch 200 is applied to the patient's tumor site, potentially affecting treatment effectiveness, all main bodies 2111 of the flexible circuit board 211 are spaced apart within an area measuring a maximum of 219 mm x 163 mm. The diameter of the main body 2111 is 21-22 mm. The maximum spacing between two adjacent main bodies 2111 in adjacent rows of the flexible circuit board 211 is approximately 28 mm, and the maximum spacing between two adjacent main bodies 2111 in adjacent columns of the flexible circuit board 211 is approximately 50 mm. In other words, the maximum spacing between two main bodies 2111 in adjacent rows of the same column is approximately 28 mm, and the maximum spacing between two main bodies 2111 in adjacent columns of the same column is 50 mm. The maximum dimensions of the flexible circuit board 211 are suitable for most adult patients. For patients with a larger waist, the two pairs of electrode patches 200 can be applied horizontally around the patient's waist. For patients with a smaller waist, the two pairs of electrode patches 200 can be applied vertically around the patient's waist. If the patient's waist circumference is appropriate, one pair of electrode patches 200 can be applied horizontally to the patient's waist, and another pair of electrode patches 200 can be applied vertically to the patient's waist. The two pairs of electrode patches 200 are applied around the patient's waist.

[0090] The connecting portion 2112 includes a first connecting portion 2112A connecting two adjacent main bodies 2111 located in alternate columns of the same row; a second connecting portion 2112B connecting two main bodies 2111 located in adjacent rows of the same column; and a third connecting portion 2112C connecting two diagonally arranged main bodies 2111 located in adjacent rows and columns. The first connecting portion 2112A is located between two adjacent main bodies 2111 in each alternate column of each row and has the same length. The length of the first connecting portion 2112A is approximately 23-50 mm. The second connecting portion 2112B is located between two adjacent main bodies 2111 in each of the first, third, and fifth columns and has the same length. The length of the second connecting portion 2112B is approximately 1-28 mm. The length of the third connecting portion 2112C is greater than half the length of the first connecting portion 2112A. The length of the third connecting portion 2112C is greater than the length of the second connecting portion 2112B. The first connection portion 2112A and the second connection portion 2112B are both roughly arranged in an "I" shape. The third connection portion 2112C is roughly arranged in an "L" shape or in an inclined "I" shape. There are 8 third connection portions 2112C, which are respectively located between the two main bodies 2111 of the second column of the first row and the second row of the first column, between the two main bodies 2111 of the second column of the first row and the third column of the second row, between the two main bodies 2111 of the third column of the second row and the fourth column of the first row, between the two main bodies 2111 of the fourth column of the first row and the fifth column of the second row, between the two main bodies 2111 of the second column of the last row and the fourth row of the first column, between the two main bodies 2111 of the second column of the last row and the third column of the fourth row, between the two main bodies 2111 of the third column of the fourth row and the fourth column of the last row, and between the two main bodies 2111 of the fourth column of the last row and the fifth column of the fourth row. Preferably, the length of the first connection portion 2112A is greater than the diameter of the main body 2111. The length of the second connection portion 2112B is smaller than the diameter of the main body 2111. The first connection portion 2112A and the second connection portion 2112B are arranged perpendicularly, the third connection portion 2112C and the adjacent first connection portion 2112A are arranged at an acute angle, and the second connection portion 2112B and the adjacent third connection portion 2112C are also arranged at an acute angle.

[0091] The main body sections 2111 can be divided into peripheral main body sections 2111A located at the periphery of the array, and central main body sections 2111B located within the array, surrounded by the peripheral main body sections 2111A. Specifically, there are ten peripheral main body sections 2111A and three central main body sections 2111B, located in the same row. The peripheral main body sections 2111A and central main body sections 2111B are connected in pairs via connectors 2112. Two adjacent peripheral main body sections 2111A are electrically connected via either a first connector 2112A, a second connector 2112B, or a third connector 2112C. Specifically, two adjacent peripheral main bodies 2111A in the same column are connected by a second connecting portion 2112B, two adjacent peripheral main bodies 2111A in the same row are connected by a first connecting portion 2112A, and two adjacent peripheral main bodies 2111A in adjacent rows and columns and arranged diagonally are connected by a third connecting portion 2112C. The peripheral main bodies 2111A and the first connecting portion 2112A, second connecting portion 2112B, and third connecting portion 2112C between two adjacent peripheral main bodies 2111A are arranged in a generally octagonal shape with one end open. The peripheral main bodies 2111A are arranged in an axisymmetric configuration, with their axis of symmetry coinciding with the line containing the three central main bodies 2111B.

[0092] The central body portions 2111B are located in the third row of three body portions 2111. Each central body portion 2111B is connected to its adjacent peripheral body portion 2111A via either a first connection portion 2112A or a third connection portion 2112C. Two adjacent central body portions 2111B are electrically connected via a second connection portion 2112B. Specifically, the central body portion 2111B is electrically connected to its adjacent peripheral body portion 2111A in the same row via a first connection portion 2112A, and is electrically connected to its diagonally arranged peripheral body portion 2111A in an adjacent row and column via a third connection portion 2112C. This ensures that both the central body portion 2111B and its adjacent peripheral body portion 2111A are connected via at least two connection portions 2112, ensuring a relatively fixed position between the peripheral body portions 2111A and the central body portion 2111B, providing a stable connection and facilitating soldering of the dielectric component 213 to the flexible circuit board 211. Specifically, the central body portion 2111B in the third row is connected only to its adjacent peripheral body portion 2111A in the same row via the first connection portion 2112A, and is disconnected from its diagonally arranged adjacent peripheral body portion 2111A in an adjacent row and column. Each of the other two central body parts 2111B is not only connected to the peripheral body parts 2111A in adjacent rows and columns and arranged diagonally therewith through the third connection parts 2112C, but is also connected to the peripheral body parts 2111A in the same row therewith through the first connection parts 2112A.

[0093] Preferably, the main bodies 2111 of the flexible circuit board 211 are spaced apart within an area measuring 165 mm x 109 mm. The diameter of the main body 2111 is 21 mm. The spacing between main bodies 2111 in adjacent rows is 15 mm, and the spacing between main bodies 2111 in alternate columns of the same row is 23 mm. That is, the spacing between two main bodies 2111 in adjacent rows of the same row is 15 mm, and the spacing between two main bodies 2111 in adjacent columns of the same row is 23 mm. In other words, the length of the second connecting portion 2112B is approximately 15 mm, and the length of the first connecting portion 2112A is approximately 23 mm. The width of the wiring portion 113 is 8 mm. The widths of the first connecting portion 2112A, the second connecting portion 2112B, and the third connecting portion 2112C are all 4.5 mm. The areas of the first open spaces 218 formed between the multiple main bodies 2111 of the flexible circuit board 211 are not identical. In this embodiment, among all the first open spaces 218, the first open space 218 formed by the nine main bodies 2111 located in the middle three rows, which are formed by the four main bodies 2111 in the same row and in adjacent rows, has the largest area, which is approximately 1065 mm. 2The area of the first open space 218 formed by the three main bodies 2111 in the first row and its adjacent row, and in the last row and its adjacent row of the flexible circuit board 211 is the smallest. Specifically, the first open space 218 formed by the two main bodies 2111 in the same alternate row and the main body 2111 in the alternate row and diagonally arranged with the two main bodies 2111 is the smallest, and its area is approximately 470mm. 2 .

[0094] The connection portion 2113 is partially located between the multiple main bodies 2111 and partially disposed within the first open space 218 enclosed by the multiple main bodies 2111. This prevents the overall size of the flexible circuit board 2111 from being excessively large, which would otherwise increase manufacturing costs. The connection portion 2113 extends laterally from one of the two main bodies 2111 located at the ends of the three main bodies 2111 in the third row. Specifically, the connection portion 2113 extends laterally from the main body 2111 in the fourth row and third column. The connection portion 2113 extends from the central main body 2111B located at the end toward an area away from the array of main bodies 2111. The connection portion 2113 is located between two third connecting portions 2112C and is connected to the central main body 2111B located at the end. The connection portion 2113 and the two third connecting portions 2112C connected to the same central main body 2111B are arranged in a generally arrow-shaped pattern. The wiring portion 2113 extends between the two outer main body portions 2111A that are in the same row and are arranged in a disconnected state. The wiring portion 2113 and the first connecting portion 2112A are arranged approximately perpendicularly. The wiring portion 2113 and the second connecting portion 2112B are arranged approximately in parallel. The wiring portion 2113 is arranged approximately in the shape of a "one". The width of the wiring portion 2113 is at least 4 mm. Preferably, the width of the wiring portion 2113 is 4-8 mm. The angle between the wiring portion 2113 and the third connecting portion 2112C that are simultaneously connected to the same main body portion 2111 is an acute angle. In other embodiments, the wiring portion 2113 can also be arranged to extend laterally from the main body portion 2111 or the central main body portion 2111B located in the second row and third column; and the two main bodies 2111 located in the first row are arranged in a disconnected state, and the wiring portion 2113 passes through the gap between the two main bodies 2111. In other embodiments, the wiring portion 2113 may also be laterally extended from a second connection portion 2112B located between two adjacent central main body portions 2111B, and the wiring portion 2113 and the second connection portion 2112B are arranged vertically; the wiring portion 2113 and the second connection portion 2112B extending the wiring portion 2113 are roughly arranged in a "T" shape.

[0095] The support member 23 is a rectangular sheet with rounded corners and a plurality of through holes 230 in the middle. It is directly adhered to the backing 22 in a ring-shaped manner around the sides of two or three dielectric elements 213 located in the same row. The portion of the support member 23 located around the dielectric element 213 along its width extends into the first open space 218. The adhesive member 25 is a rectangular sheet with rounded corners and covers the support member 23 as a whole. The length and width of the adhesive member 25 are slightly larger than the length and width of the support member 23. As described in the first embodiment, the adhesive member 25 also includes a portion covering the side of the dielectric element 213 facing the patient's skin, a portion covering the side of the support member 23 facing the patient's skin, and a portion covering the side of the support member 23 along its thickness direction. The portion of the adhesive member 25 covering the side of the support member 23 facing the patient's skin extends into the first open space 218 and covers a portion of the first open space 218. The portion of the first open space 218 not covered by the adhesive member 25 or the support member 23 is the second open space 219, which allows the patient's skin to breathe freely and dissipate heat through ventilation. Since the width of the adhesive member 25 and the support member 23 will affect the efficient ventilation area of the first open space 218, it is recommended to adopt the following sizing method for the adhesive member 25 and the support member 23: the width of the support member 23 is 1-8 mm larger than the diameter of the dielectric element 213; the flat width of the adhesive member 25 is 2-14 mm longer than the width of the support member 23; and considering that the edge of the adhesive member 25 covers the side end surface of the support member 23 (with a thickness of 1 mm), the width of the adhesive member 25 after covering the support member 23 is 0-12 mm larger than the width of the support member 23. That is, the distance that the adhesive member 25 extends into the first open space 218 along its width is 0.5-10 mm.

[0096] In this embodiment, the diameter of the dielectric element 213 is 20 mm, the width of the support member 23 is 25 mm, the thickness of the support member 23 is 1 mm, and the width of the adhesive member 25 is 27-29 mm. The length of the adhesive member 25 is slightly longer than the length of the support member 23, and the length of the support member 23 is slightly longer than the length of the entire row of dielectric elements 213, but there are no specific restrictions. While ensuring their respective functions, the support member 23 and the adhesive member 25 are designed to be as narrow as possible to maximize the role of the first open space 218. It can be understood that multiple second open spaces 219 are formed between the multiple adhesive members 25 arranged at intervals, and the size of the second open space 219 is smaller than the size of the first open space 218. In this embodiment, the column spacing between two adjacent dielectric elements 213 is 16 mm, the spacing between two adjacent support members 23 is 11 mm, and the spacing between two adjacent adhesive members 25 is 9 mm, that is, the width of the second open space 219 is 9 mm.

[0097] When the electrode patch 200 is in use, most of the first open space 218 is completely open to the outside through the second open space 219 to ventilate and dissipate heat. The part of the first open space 218 covered by the support member 23 and the adhesive member 25 absorbs moisture through the support member 23 and the adhesive member 25. During the tumor electric field therapy process, the heat accumulated on the skin surface corresponding to the patient's electrode patch 200 and the water vapor generated by sweating can be discharged into the outside air through the second open space 219, avoiding skin erythema, itching, follicular inflammation, pain, papules and other skin discomfort symptoms.

[0098] Variations of the second embodiment of the electrode patch

[0099] Figures 15 to 17 The electrode patch 200' shown in this embodiment is also applied to the surface of a patient's torso for tumor electric field therapy (TFET) of tumors located on the torso. It also includes a flexible backing 22', an electrical functional component 21' adhered to the backing 22', a support 23' adhered to the backing 22', a wire 24' electrically connected to the electrical functional component 21', and an adhesive 25' adhered to the support 23'. The electrical functional component 21' also includes a flexible printed circuit board 211', multiple insulating plates 212' and multiple dielectric elements 213' disposed on opposite sides of the flexible printed circuit board, and multiple temperature sensors 214' affixed to the flexible printed circuit board 211'. The main body 2111' of the flexible printed circuit board 211', the dielectric elements 213', and the insulating plates 212' are disposed in a one-to-one correspondence and constitute the electrode unit 210' of the electrical functional component 21'. Similar to the electrode patch 200 in the second embodiment, the electrode patch 200 ′ is provided with 13 electrode units 210 ′ arranged in five rows and five columns. The specific distribution positions are consistent with the arrangement of the electrode units 210 in the second embodiment.

[0100] The electrode patch 200' in this embodiment has a substantially identical structure to the electrode patch 200 in the second embodiment, differing in that the peripheral main body portions 2111A' of the flexible printed circuit board 211' of the electrical functional component 21' of the electrode patch 200' are all connected in pairs via connecting portions 2112', while the central main body portion 2111B' is only connected to its adjacent peripheral main body portion 2111A' located in the same row. Specifically, adjacent peripheral main body portions 2111A' are connected in pairs via first connecting portions 2112A', second connecting portions 2112B', or third connecting portions 2112C'. The peripheral main body portions 2111A' and the first connecting portions 2112A', second connecting portions 2112B', and third connecting portions 2112C' located between adjacent peripheral main body portions 2111A' generally form a racetrack-like structure. The central body portion 2111B' is connected to the peripheral body portion 2111A' in the same row via a first connecting portion 2112A'. The central body portion 2111B' is disconnected from the diagonally arranged peripheral body portions 2111A' in adjacent rows and columns. Two adjacent central body portions 2111B' of the three central body portions 2111B' are disconnected. No second connecting portion 2112B' is provided between two adjacent disconnected central body portions 2111B'. The third connecting portion 2112C' is arcuate. There are four third connecting parts 2112C', which are respectively located between the two peripheral main body parts 2111A' of the second column of the first row and the second row of the first column, between the two peripheral main body parts 2111A' of the fourth column of the first row and the fifth column of the second row, between the two peripheral main body parts 2111A' of the second column of the last row and the fourth row of the first column, and between the two peripheral main body parts 2111A' of the fourth column of the last row and the fifth column of the fourth row. The third connecting part 2112C' and the adjacent first connecting part 2112A' are both roughly arranged at an obtuse angle or an acute angle. The third connecting part 2112C' and the adjacent second connecting part 2112B' are both roughly arranged at an obtuse angle. The diameter of the peripheral main body part 2111A' is the same as that of the central main body part 2111B', and the length of the second connecting part 2112B' is slightly larger than the diameter of the peripheral main body part 2111A'.

[0101] The connection portion 2113' extends laterally from a second connection portion 2112B'. Specifically, the connection portion 2113' extends laterally from the second connection portion 2112B' located between two adjacent central body portions 2111B'. The connection portion 2113' and the second connection portion 2112B' extending from the connection portion 2113' are arranged in a roughly "T" shape. The connection portion 2113' and the second connection portion 2112B' are arranged perpendicularly. The connection portion 2113' and the first connection portion 2112A' are arranged roughly parallel.

[0102] The flexible circuit board 211' also has a reinforcing portion 2116' arranged opposite to the wiring portion 2113', which can provide traction for the wiring portion 2113' to prevent uneven force from affecting the application of the electrode patch 200' when the electrode patch 200' is applied to the surface of the patient's tumor area. Specifically, the reinforcing portion 2116' is extended from the second connecting portion 2112B' of the wiring portion 2113' that is extended laterally. The reinforcing portion 2116' and the wiring portion 2113' are respectively located on opposite sides of the second connecting portion 2112B' connected to the wiring portion 2113'. One end of the reinforcing portion 2116' is connected to the second connecting portion 2112B' connected to the wiring portion 2113', and the other end is connected to the second connecting portion 2112B' adjacent to the second connecting portion 2112B' and located between two adjacent peripheral main body portions 2111A'. The reinforcing portion 2116' is provided as a bridge between two adjacent and parallel second connecting portions 2112B'. The reinforcing portion 2116', the connecting portion 2113' and the second connecting portion 2112B' connected to the connecting portion 2113' are generally arranged in a cross shape.

[0103] The backing 22' is provided with a threading hole 221' corresponding to the connection portion 2113' of the flexible printed circuit board 211'. One end of a wire 24' passes through the threading hole 221' and is electrically connected to the connection portion 2113'. The wire 24' extends from one side of the backing 22' into the flexible printed circuit board 211' and connects to the connection portion 2113'. This prevents a large amount of wire 24' from being directly pressed against the patient's skin, which could reduce the comfort of the electrode patch 200' during application.

[0104] The main body portions 2111' are arranged in a spaced-apart pattern, forming a first open space 218' between adjacent main body portions 2111'. This allows the skin covering the patient's tumor site, covered by the electrode patch 200', to breathe freely after the electrode patch 200' is applied to the patient's body. The following details the dimensions of the main body portion 2111', connecting portion 2112', and wiring portion 2113' of the electrical functional component 21', as well as the dimensions of the first open space 218'.

[0105] All main bodies 2111' of the flexible circuit board 211' are spaced apart within an area with a minimum length of 193 mm and a minimum width of 109 mm. That is, the minimum dimensions of the flexible circuit board 211' are 193 mm x 109 mm. The spacing between main bodies 2111' in adjacent rows of the flexible circuit board 211' is greater than the diameter of the main body 2111', at least 22 mm. That is, the length of the second connecting portion 2112B' is greater than the diameter of the main body 2111', at least 22 mm. The third connecting portion 2112C' is arranged in an arc shape. The length of the third connecting portion 2112C' is at least 26.7 mm. The width of the reinforcing portion 2116' is 4.5-6 mm.

[0106] Among all the first open spaces 218', the first open space 218' formed by the five main bodies 2111' located between the first row and the second row has the largest area, and the first open space 218' located in the middle three rows and formed by the four main bodies 2111' located in adjacent rows of the interval column and accommodating the reinforcement portion 2116' has the smallest area.

[0107] As described in the first and second embodiments, the support member 23' is disposed around the dielectric member 213', with the dielectric member 213' passing through its through hole 230'. The support member 23' is directly adhered to the backing 22', and the adhesive member 25' is applied to the support member 23' to cover the support member 23'. Both the support member 23' and the adhesive member 25' extend into the first open space 218' in the width direction and partially cover the first open space 218'. The first open space 218' is covered by the support member 23' and the adhesive member 25' to form a second open space 219'. In order to allow the patient's skin to breathe freely and dissipate heat in the first open space 218' to the greatest extent, it is recommended to adopt the same size design method for the adhesive member 25' and the support member 23'. The width of the support member 23' is 1-8 mm larger than the diameter of the dielectric element 213', and the flat width of the adhesive member 25' is 2-14 mm longer than the width of the support member 23'. Considering that the edge of the adhesive member 25' covers the side end surface of the support member 23' (the thickness is 1 mm), the width of the adhesive member 25' after covering the support member 23' is 0-12 mm larger than the width of the support member 23', that is, the distance that the adhesive member 25' extends into the first open space 218' along its width is 0.5-10 mm. In this embodiment, the diameter of the dielectric element 213' is 20 mm, the width of the support member 23' is 25 mm, and the width of the adhesive member 25' is 27-29 mm. In this embodiment, the columnar spacing between two adjacent dielectric elements 213' is 25 mm, the spacing between two adjacent support members 23' is 20 mm, and the spacing between two adjacent adhesive members 25' is 18 mm.

[0108] Third embodiment of the electrode patch

[0109] Figures 18 to 20 The electrode patch 300 of the third embodiment is shown, which is also applied to the surface of the patient's torso and is used to perform tumor electric field therapy on the tumor site located on the torso. The electrode patch 300 also includes a flexible backing 32, an electrical functional component 31 adhered to the backing 32, a support member 33 adhered to the backing 32, a wire 34 electrically connected to the electrical functional component 31, and an adhesive member 35 adhered to the electrical functional component 31 and the support member 33.

[0110] The electrical functional components 31 of the electrode patch 300 include a flexible circuit board 311, multiple insulating plates (not shown), multiple dielectric elements 313, and multiple temperature sensors 314 disposed on the flexible circuit board 311. The insulating plates (not shown) and dielectric elements 313 are disposed on opposite sides of a main body 3111 on the flexible circuit board 311, forming a plurality of electrode units 310. The electrode patch 300 in this embodiment includes 13 electrode units and is substantially identical to the electrode patch 200 in the second embodiment. The difference between the two is that the 13 main bodies 3111 of the electrode patch 300 are arranged in an array of five rows and three columns, rather than five rows and five columns. From a column arrangement perspective, the first and third columns each have five main bodies 3111, while the second column has three main bodies 3111. Specifically, the two main bodies 3111 in the first row are located in the first and third columns, respectively. The two main bodies 3111 in the last row are also located in the first and third columns, respectively. The three main bodies 3111 in each of the three middle rows are located in the first column, the second column and the third column respectively. The main bodies 3111 located in the first row and the last row are arranged in alternate columns, and the main bodies 3111 located in the first row and the last row are arranged in a disconnected state. The spacing between two adjacent main bodies 3111 in the same row is not equal. The spacing between two adjacent main bodies 3111 in the same column is equal. The 13 main bodies 3111 are arranged in an axially symmetrical manner, one of which coincides with the straight line of the three main bodies 3111 located in the third row, and the other of which coincides with the straight line of the three main bodies 3111 located in the second column. The 13 main bodies 3111 are also arranged in a centrally symmetrical manner, and their center of symmetry coincides with the center of the main body 3111 located in the third row and the third column. The electrode units 310 are arranged in the same manner as the main bodies 3111, and are located in the array area of five rows and three columns.

[0111] Based on their distribution within the array, the main body portions 3111 can be divided into 12 peripheral main body portions 3111A located at the periphery of the array and one central main body portion 3111B surrounded by the peripheral main body portions 3111A and located within the array. Specifically, the central main body portion 3111B is the main body portion 3111 located in the third row, second column. The 12 peripheral main body portions 3111A are all the main body portions 3111 except the main body portion 3111 located in the third row, second column. The peripheral main body portions 3111A are connected either by a second connecting portion 3112B or a third connecting portion 3112C. Two adjacent peripheral main body portions 3111A in the same column are connected by a second connecting portion 3112B. Two diagonally arranged peripheral main body portions 3111A located in adjacent rows and columns are connected by a third connecting portion 3112C. Two adjacent peripheral main body portions 3111A located in alternate columns of the same row are disconnected. The peripheral main body portion 3111A and the central main body portion 3111B are connected via either the first connection portion 3112A or the second connection portion 3112B.

[0112] Specifically, the peripheral main body portions 3111A and the central main body portion 3111B located adjacent to each other in the same row are connected by a first connecting portion 3112A. The peripheral main body portions 3111A and the central main body portion 3111B located adjacent to each other in the same column are connected by a second connecting portion 3112B. The first connecting portion 3112A is located between two main body portions 3111 in adjacent columns in the same row and has the same length. The second connecting portion 3112B is located between two main body portions 3111 in adjacent rows in the same column and has the same length. The length of the third connecting portion 3112C is greater than the length of the first connecting portion 3112A. There are four third connecting portions 3112C, which are located respectively between the two peripheral main body portions 3111A in the first column of the first row and the second column of the second row, between the two peripheral main body portions 3111A in the second column of the second row and the third column of the first row, between the two peripheral main body portions 3111A in the first column of the fifth row and the second column of the fourth row, and between the two peripheral main body portions 3111A in the second column of the fourth row and the third column of the fifth row. The peripheral body portion 3111A is arranged in an axisymmetric pattern, with one axis of symmetry coinciding with the direction of extension of the row of the central body portion 3111B, and the other axis of symmetry coinciding with the direction of extension of the column of the central body portion 3111B. The connecting portion 3113 extends from the peripheral body portion 3111A located in the fourth row, second column. The connecting portion 3113 is located between two adjacent third connecting portions 3112C that are connected to the same peripheral body portion 3111A.

[0113] The backing 32 is provided with a threading hole 321 corresponding to the connection portion 3113 of the flexible printed circuit board 311. One end of the wire 34 passes through the threading hole 321 and is electrically connected to the connection portion 3113. The wire 34 extends from one side of the backing 32 into the flexible printed circuit board 311 and connects to the connection portion 3113. This prevents a large amount of wire 34 from being directly pressed against the patient's skin, which could reduce the comfort of the electrode patch 300 during application.

[0114] The electrode patch 300 forms a plurality of first open spaces 318 between the plurality of electrode units 310 and the respective connecting portions 3112. As described in the preceding embodiments, the support member 33 surrounds the periphery of the dielectric element 213 disposed in the same arrangement, with the dielectric element 313 passing through its through-holes 330, and is directly adhered to the backing 32. One side of the support member 33 extends into the first open spaces 318 in the width direction. The corresponding portion of the adhesive member 35 applied to the support member 33 also extends into the first open spaces 318 and partially covers the corresponding first open spaces 318. The space after the first open spaces 318 are partially covered by the support member 33 and / or the adhesive member 35 forms a second open space 319 that allows ventilation and heat dissipation from the patient's skin. The portion of the first open space 318 covered by the support member 33 and the adhesive member 35 absorbs moisture through the adhesive member 35 and the support member 33. To minimize the impact on the efficient ventilation area of the first open space 318, the following dimensional design is recommended for the adhesive member 35 and the support member 33: the width of the support member 33 is 1-8 mm larger than the diameter of the dielectric element 313, and the flat width of the adhesive member 35 is 2-14 mm longer than the width of the support member 33. Considering that the edge of the adhesive member 35 covers the side end surface of the support member 33 (with a thickness of 1 mm), the width of the adhesive member 35 after covering the support member 33 is 0-12 mm larger than the width of the support member 33. That is, the distance that the adhesive member 35 extends into the first open space 318 along its width is 0.5-10 mm. In this embodiment, the diameter of the dielectric element 313 is 20 mm, the width of the support member 33 is 25 mm, and the width of the adhesive member 35 is 27-29 mm. In this embodiment, the column spacing between two adjacent dielectric elements 313 is 25 mm, the spacing between two adjacent support members 33 is 20 mm, and the spacing between two adjacent adhesive members 35 is 18 mm. When the electrode patch 300 is in use, most of the first open space 318 is ventilated and dissipated outward through the second open space 319 which is completely open and formed by the gaps between adjacent adhesive members 35. The portion of the first open space 318 covered by the support member 33 and the adhesive member 35 absorbs moisture through the support member 33 and the adhesive member 35.

[0115] Fourth embodiment of the electrode patch

[0116] refer to Figures 21 to 23As shown, the electrode patch 400 of this embodiment includes a backing 42, an electrical component 41 adhered to the backing 42, several supports 43 adhered to the backing 42, wires 44 electrically connected to the electrical component 41, and several adhesive members 45 covering the corresponding portions of the supports 43 and the electrical component 41. The electrode patch 400 is attached to the patient's body surface corresponding to the tumor site via the backing 42, and the electrical component 41 applies an alternating electric field to the patient's tumor site to disrupt or prevent mitosis of the patient's tumor cells, thereby achieving the purpose of tumor treatment.

[0117] The electrical functional assembly 41 includes a flexible printed circuit board 411 having several main bodies 4111, a plurality of insulating plates 412 and dielectric elements 413 disposed on opposite sides of the main bodies 4111, and a plurality of temperature sensors 414 selectively secured to the main bodies 4111. The main bodies 4111, the corresponding insulating plates 412, the corresponding dielectric elements 413, and the temperature sensors 414 selectively disposed within through-holes 4132 extending through the dielectric elements 413 form electrode units 410. The electrode units 410 are arranged in an array. The flexible printed circuit board 411 also includes a plurality of connecting portions 4112 connecting to the electrode units 410, and a wiring portion 4113 extending laterally from a connecting portion 4112 and electrically connected to the wire 44. In this embodiment, the electrode patch 400 is provided with 20 electrode units, which increases the coverage area of the electrode patch 400, enhances the electric field strength applied to the tumor site for tumor electric field therapy, and increases the range of the alternating electric field covering the tumor site, thereby improving the therapeutic effect.

[0118] The structure of the electrode unit 410 is the same as the electrode unit 110 of the electrode patch 100 in the first embodiment. For related content, please refer to the relevant content of the electrode patch 100 in the first embodiment and will not be repeated here. The main difference between the electrode patch 400 in this embodiment and the electrode patch 100 in the first embodiment is the different number and arrangement of the electrode units 410, as well as some adjustments made due to the different number and arrangement of the electrode units 410, including the arrangement, row spacing, column spacing, the setting method of the connection part, the setting method of the wiring part, and various dimensions, etc. The following will focus on these differences. For other content, please refer to the relevant content of the electrode patch 100 in the first embodiment.

[0119] There are twenty electrode units 410, which are distributed in an array area of four rows and six columns. Each electrode unit 410 is connected to at least three adjacent electrode units 410 through a connecting portion 4112. Each electrode unit 410 is connected to at least three connecting portions 4112. The number of electrode units 410 in each column is not exactly the same. At least two adjacent electrode units 410 in the plurality of electrode units 410 are arranged in a disconnected state, and a gap 4C is formed between the two adjacent electrode units 410 arranged in a disconnected state and for the wiring portion 4113 to pass through. The wiring portion 4113 is extended laterally from the connecting portion 4112 opposite to the gap 4C. The connecting portion 4112 extending the wiring portion 4113 is arranged perpendicular to the wiring portion 4113, and the two are arranged roughly in a "T" shape. The wiring portion 4113 is arranged roughly in an "I" shape. Optionally, the connection portion 4113 is arranged in a "T" shape and is connected between two connecting portions 4112 that are respectively connected to two adjacent electrode units 410 arranged in a disconnected manner. The connection portion 4113 is located between the multiple electrode units 410 and is arranged in the space enclosed by the multiple electrode units 410. This can prevent the overall size of the electrical functional component 41 from being too large, which would lead to increased manufacturing costs.

[0120] The twenty electrode units 410 are arranged in an array area of four rows and six columns, with two columns each having two electrode units 410, and the remaining four columns each having four electrode units 410. Specifically, the twenty electrode units 410 are distributed in an array area of four rows and six columns, with four columns each having four electrode units 410 adjacent to each other. The spacing between two adjacent electrode units 410 arranged in a row is the same. The multiple connecting portions 4112 connecting two adjacent electrode units 410 arranged in a row have the same length. Specifically, the electrode units 410 in each of the two columns having only two electrode units 410 are arranged in adjacent rows, the spacing between two adjacent electrode units 410 arranged in a column is the same, and the multiple connecting portions 4112 connecting two adjacent electrode units 410 arranged in a column have the same length. The four electrode units 410 in the two columns can be arranged in a row-aligned manner; they can also be arranged in a row-staggered manner; or one can be arranged in a row-aligned manner and the other can be arranged in a row-staggered manner. Optionally, the two electrode units 410 in at least one of the two columns having only two electrode units 410 are arranged in alternating rows, the spacing between the electrode units 410 arranged in a column is different, and the multiple connecting portions 4112 connecting two adjacent electrode units 410 in a column have different lengths.

[0121] The connecting portion 4112 connects all two adjacent electrode units 410 located at the periphery of the array, and at least one of the two adjacent electrode units 410 located in the inner layer of the array is arranged in a disconnected state. Specifically, the connecting portion 4112 is provided between all two adjacent electrode units 410 except between the two electrode units 410 located between the second row and third column and the second row and fourth column, and between the two electrode units 410 located between the third row and third column and the third row and fourth column. The lengths of the connecting portions 4112 connecting two adjacent electrode units 410 arranged in a row are equal. The lengths of the connecting portions 4112 connecting two adjacent electrode units 410 arranged in a column are equal. The connecting portions 4112 are located between two adjacent electrode units 410 arranged in a row, between two electrode units 410 arranged in a column, and between two adjacent electrode units 410 located at the periphery of the array and diagonally arranged in adjacent rows and adjacent columns.

[0122] Based on the distribution of the electrode units 410 in the array, the multiple electrode units 410 can be divided into a plurality of peripheral electrode units 410A located at the periphery and a plurality of central electrode units 410B surrounded by the peripheral electrode units 410A. In this embodiment, there are 12 peripheral electrode units 410A and 8 central electrode units 410B. All peripheral electrode units 410A are connected in pairs by connecting portions 4112. That is, the connecting portions 4112 are provided between all adjacent peripheral electrode units 410A. At least two of the multiple central electrode units 410B are separated from each other in the same row or column, and a gap 4C is formed between the two to allow the wiring portion 4113 to pass through.

[0123] The gap 4C is provided between two adjacent electrode units 410 located in the second row, third column and the second row, fourth column, and between two adjacent electrode units 410 located in the third row, third column and the third row, fourth column. The wiring portion 4113 is located between the two columns of electrode units 410 in the third column and the fourth column. The wiring portion 4113 is generally T-shaped, passing through the gap 4C and bridging the connection portion 4112 between the two adjacent electrode units 410 in the middle of the third column and the connection portion 4112 between the two adjacent electrode units 410 in the middle of the fourth column. The wiring portion 4113 and the two adjacent connection portions 4112 connected thereto are arranged in an axially symmetrical manner. Optionally, the wiring portion 4113 is arranged in an I-shape and extends laterally from the connection portion 4112 corresponding to the gap 4C toward the gap 4C.

[0124] refer to Figure 23As shown, the main body 4111 of the electrode unit 410, arranged in four rows and six columns, the connecting portion 4112 connecting two adjacent electrode units 410, and the wiring portion 4113 extending between two adjacent connecting portions 4112, together constitute the flexible circuit board 411 of the electrical functional component 41. The flexible circuit board 411 is arranged in a grid pattern. The dielectric elements 413 are arranged at the grid points of the flexible circuit board 411. It can be understood that the main body 4111 is a grid point of the flexible circuit board 411. From the perspective of the formation of the electrode unit 410, the insulating plate 412 is arranged on the side of the main body 4111 of the flexible circuit board 411 away from the human skin, the dielectric element 413 is arranged on the side of the main body 4111 of the flexible circuit board 411 facing the human skin, and the temperature sensor 414 is optionally arranged on the side of the main body 4111 of the flexible circuit board 411 facing the human skin. The arrangement of the main body 4111 of the flexible circuit board 411 is consistent with the arrangement of the electrode units 410.

[0125] In this embodiment, the electrode patch 400 is provided with 10 support members 43, each support member 43 having two through-holes 430 extending therethrough, each for accommodating two adjacent electrode units 410 in the same column. Adhesive members 45 are provided corresponding to the number of support members 43 and are applied to the support members 43 and the electrode units 410. A plurality of adjacent electrode units 410 are arranged in a spaced-apart manner and a first open space 418 is formed between the plurality of adjacent electrode units 410. This allows the skin on the patient's tumor site covered by the electrode patch 400 to breathe freely after the electrode patch 400 is placed on the patient's tumor site. The following describes in detail the dimensions of the electrode units 410, the connecting portion 4112, the wiring portion 4113 of the electrical functional component 41, and the dimensions of the first open space 418.

[0126] The electrode units 410 are generally circular sheet-shaped, with a diameter of approximately 21-12 mm. The spacing between two adjacent electrode units 410 arranged in a row is the same. The spacing between two adjacent electrode units 410 in the same row is at least 8 mm. The spacing between two adjacent electrode units 410 arranged in a column is the same. The spacing between two adjacent electrode units 410 in the same column is at least 6.5 mm. The spacing between two adjacent electrode units 410 in adjacent rows and columns and arranged diagonally is the same. The spacing between two adjacent electrode units 410 in adjacent rows and columns and arranged diagonally is at least approximately 19 mm.

[0127] The electrical functional component 41 is generally octagonal, with a minimum length of 166 mm and a minimum width of 103.5 mm. That is, all electrode units 410 of the electrical functional component 41 are spaced apart within an area measuring at least 166 mm x 103.5 mm. This size of electrode patch is suitable for children with smaller waistlines.

[0128] To prevent overlap of the electrical functional components 41 after the electrode patch 400 is applied to the patient's tumor site, which could affect treatment effectiveness, the maximum spacing between adjacent electrode units 410 in the same row is 22 mm, the maximum spacing between adjacent electrode units 410 in the same column is 25 mm, and the spacing between adjacent electrode units 410 in adjacent rows and columns arranged diagonally is at least approximately 33.3 mm. Given the maximum diameter of the electrode units 410 of 22 mm, the electrical functional component 41 has a maximum length of 242 mm and a maximum width of 166 mm. In other words, all electrode units 410 of the electrical functional component 41 are spaced apart within an area of a maximum of 242 mm x 166 mm. The maximum dimensions of the electrical functional component 41 are suitable for most adult patients. For patients with a larger waist circumference, the two pairs of electrode patches 400 can be applied horizontally around the patient's waist. For patients with a smaller waist circumference, the two pairs of electrode patches 400 can be applied vertically around the patient's waist. If the patient's waist circumference is appropriate, one pair of electrode patches 400 can be applied horizontally to the patient's waist, and another pair of electrode patches 400 can be applied vertically to the patient's waist. The two pairs of electrode patches 400 are applied around the patient's waist.

[0129] The length of the multiple connecting portions 4112 connecting two adjacent electrode units 410 in the same row is approximately 8-22 mm, and the length of the multiple connecting portions 4112 connecting two adjacent electrode units 410 in the same column is approximately 6.5-25 mm.

The width of all connecting portions 4112 located between two adjacent electrode units 410 is 4.5-6 mm. Preferably, the width of the connecting portion 4112 is 4.5 mm.

[0130] The wiring portion 4113 is located between the plurality of electrode units 410 and is disposed within the first open space 418 enclosed by the plurality of electrode units 410. This prevents the overall size of the electrical functional component 41 from being too large, which would otherwise increase manufacturing costs. The wiring portion 4113 includes a bridging segment 4113A that bridges between two opposing connecting portions 4112 and a wiring segment 4113B that is connected to the wire 4. The wiring segment 4113B is arranged perpendicular to the bridging segment 4113A. The bridging segment 4113A of the wiring portion 4113 is arranged perpendicular to the two connecting portions 4112 it connects to, while the wiring segment 4113B of the wiring portion 4113 is arranged parallel to the two connecting portions 4112 it connects to. The bridging segment 4113A of the wiring portion 4113 bridges between two adjacent connecting portions 4112 located in the middle, and the wiring segment 4113B of the wiring portion 4113 extends laterally from the middle of the bridging segment 4113A. The width of the wiring segment 4113B of the wiring portion 4113 is at least 4 mm, and the spacing between the wiring segment 4113B of the wiring portion 4113 and the adjacent electrode unit 410 is at least 2 mm. Preferably, the width of the wiring segment 4113B of the wiring portion 4113 is 4-8 mm. The width of the bridging segment 4113A of the wiring portion 4113 is 4.5-6 mm, and the spacing between the bridging segment 4113A of the wiring portion 4113 and the adjacent electrode unit 410 is at least 1 mm. Preferably, the width of the bridging segment 4113A of the wiring portion 4113 is the same as the width of the connecting portion 4112. The gold finger 41130 soldered to the wire 44 is provided on the wiring segment 4113B.

[0131] Preferably, in this embodiment, reference Figure 21 and Figure 22As shown, the diameter of the electrode unit 410 is 21 mm. The spacing between two adjacent electrode units 410 arranged in a row is 23 mm. The spacing between two adjacent electrode units 410 arranged in a column is 15 mm. The length of multiple connecting portions 4112 connecting two adjacent electrode units 410 in the same row is 23 mm, the length of multiple connecting portions 4112 connecting two adjacent electrode units 410 in the same column is 15 mm, and the length of multiple connecting portions 4112 connecting two adjacent electrode units 410 located in adjacent rows and columns and arranged diagonally is approximately 27.5 mm. The width of the connecting portion 4112 is 4.5 mm. The width of the bridging section 4113A of the wiring portion 4113 is 4.5 mm, the width of the wiring segment 4113B of the wiring portion 4113 is 8 mm, and the length of the wiring segment 4113B of the wiring portion 4113 is 42 mm. The length of the electrical functional component 41 is 201 mm and the width is 153 mm. The areas of the first open spaces 418 formed between the plurality of electrode units 410 of the electrical functional component 41 are not uniform. In this embodiment, the first open spaces 418 located between the eight electrode units 410 in the two middle rows and through which the wiring portion 4113 passes are the largest, at approximately 4428 mm. 2 The first open spaces 418 located at the four corners of the electrical functional component 41 have the smallest area. The first open spaces 418 located at the corners of the electrical functional component 41 are formed by three electrode units 410 arranged diagonally, with two adjacent rows and columns, and two adjacent rows and columns. The area is approximately 452mm. 2 The area of the first open space 418 formed by the four electrode units 410 located in adjacent rows and columns is approximately 1066 mm. 2 .

[0132] As described in the previous embodiments, the support member 43 is placed around the dielectric element 413 on the circumferential side of two adjacent dielectric elements 413 in the same row and is directly adhered to the backing 42, with a portion thereof extending into the first open space 418. The adhesive member 45 completely covers the support member 43 and a portion thereof along the width direction also extends into the first open space 418 and covers a portion of the first open space 418. The portion of the first open space 418 covered by the adhesive 45 and support 43 forms a second open space 419 located between adjacent adhesives 45. The size of the second open space 419 affects the effective ventilation area of the first open space 418. The following dimensional design is recommended for the adhesive 45 and support 43: the width of the support 43 is 1-8 mm larger than the diameter of the dielectric element 413, and the flat width of the adhesive 45 is 2-14 mm longer than the width of the support 43. Considering that the edge of the adhesive 45 covers the side end surface of the support 43 (with a thickness of 1 mm), the width of the adhesive 45 after covering the support 43 is 0-12 mm larger than the width of the support 43. That is, the distance that the adhesive 45 extends into the first open space 418 along its width direction is 0.5-10 mm. In this embodiment, the diameter of the dielectric element 413 is 20 mm, the width of the support 43 is 25 mm, and the width of the adhesive 45 is 27-29 mm. In this embodiment, the row spacing between two adjacent dielectric elements 413 is 16 mm, the spacing between two adjacent support members 43 is 11 mm, and the spacing between two adjacent adhesive members 45 is 9 mm. The electrode units 410 in the middle column are covered by two adhesive members 45 spaced apart, and the column spacing between the two adhesive members 45 in the same column is 16 mm.

[0133] When electrode patch 400 is in use, most of first open space 418 is fully open to the outside through second open space 419, allowing ventilation and heat dissipation. The portion of first open space 418 covered by support member 43 and adhesive member 45 absorbs moisture through these two members. During tumor electric field therapy, heat accumulated on the patient's skin surface where electrode patch 400 is applied and moisture generated by sweat are discharged into the outside air through second open space 419, preventing skin discomfort such as erythema, itching, follicular inflammation, pain, and papules.

[0134] Fifth embodiment of the electrode patch

[0135] refer to Figures 24 to 26As shown, the electrode patch 500 of this embodiment includes a backing 52 having threading holes 521, an electrical functional component 51 adhered to the backing 52, a support member 53 adhered to the backing 52, an adhesive member 55 covering the support member 53 and the corresponding portion of the electrical functional component 51, and a wire 54 electrically connected to the electrical functional component 51. The electrical functional component 51 is arranged in a grid shape, and includes a plurality of electrode units 510 arranged in a rectangular array, a plurality of connecting portions 5112 connecting two adjacent electrode units 510, and a wiring portion 5113 electrically connected to the wire 54. Each electrode unit 510 is connected to at least two adjacent electrode units 510 via a connecting portion 5112. Each electrode unit 510 is connected to at least two connecting portions 5112. The plurality of electrode units 510 are distributed at intervals on the grid points of the electrical functional component 51. The electrode patch 500 in this embodiment is substantially the same as the electrode patch 400 in the fourth embodiment, with the only difference being the specific arrangement of the electrode units 510 on the electrical functional component 51 . Only the differences are described below, and for other details, reference may be made to the fourth embodiment.

[0136] In this embodiment, the plurality of electrode units 510 of the electrical functional component 51 are arranged in four rows and five columns. The number of electrode units 510 in the electrical functional component 51 is 20. The number of electrode units 510 in each row is the same, and the number of electrode units 510 in each column is also the same. The number of electrode units 510 in each row is 5, and the number of electrode units 510 in each column is 4.

[0137] The spacing between two adjacent electrode units 510 arranged in a row is equal, and the spacing between two adjacent electrode units 510 arranged in a column is also equal. Two adjacent electrode units 510 in the same row are arranged in adjacent columns, and two adjacent electrode units 510 in the same column are arranged in adjacent rows. The connecting portion 5112 is located between two adjacent electrode units 510 in the same row or in the same column. A plurality of connecting portions 5112 connecting two adjacent electrode units 510 arranged in a row have the same length. A plurality of connecting portions 5112 connecting two adjacent electrode units 510 arranged in a column have the same length. The spacing between two adjacent electrode units 510 arranged in a row is different from the spacing between two adjacent electrode units 510 arranged in a column. That is, the length of the connecting portion 5112 located between two adjacent electrode units 510 arranged in a row is different from the length of the connecting portion 5112 located between two adjacent electrode units 510 arranged in a column. Optionally, the spacing between two adjacent electrode units 510 arranged in a row is the same as the spacing between two adjacent electrode units 510 arranged in a column. That is, the length of the connecting portion 5112 between two adjacent electrode units 510 arranged in a row is the same as the length of the connecting portion 5112 between two adjacent electrode units 510 arranged in a column.

[0138] At least two adjacent electrode units 510 among the plurality of electrode units 510 are arranged in a disconnected manner. A gap 5C is formed between the two adjacent electrode units 510 arranged in a disconnected manner, through which the wiring portion 5113 passes. The wiring portion 5113 can be arranged in an "I" shape and extended laterally from a connecting portion 5112 opposite to the gap 5C, or it can be arranged in a "T" shape and spanned between the two connecting portions 5112 respectively connected to the two electrode units 510 arranged in a disconnected manner. The electrode units 510 arranged in a disconnected manner are located in the inner layer of the array area where the electrode units 510 are located. The electrode units 510 located on the periphery of the electrical functional component 51 are all connected in pairs through the connecting portions 5112. That is, all adjacent electrode units 510 located on the periphery of the electrical functional component 51 are connected in pairs through the connecting portions 5112. At least one of the plurality of electrode units 510 is arranged in a disconnected manner between two adjacent electrode units 510 located in adjacent rows and columns and arranged diagonally. The wiring portion 5113 is located between the plurality of electrode units 510 , which can prevent the overall size of the electrical functional component 51 from being too large, thereby increasing the manufacturing cost.

[0139] Based on the distribution of the electrode units 510 in the array, the multiple electrode units 510 can be divided into a plurality of peripheral electrode units 510A located at the periphery and a plurality of central electrode units 510B surrounded by the peripheral electrode units 510A. There are at least ten peripheral electrode units 510A and at least two central electrode units 510B. All peripheral electrode units 510A are connected to each other via connectors 5112. That is, connectors 5112 are provided between all adjacent pairs of peripheral electrode units 510A. At least one of the multiple central electrode units 510B is separated from an adjacent peripheral electrode unit 510A or central electrode unit 510B in the same row or column, with a gap 5C formed between the two for the wiring portion 5113 to pass through.

[0140] The connecting portion 5113 can be formed by extending laterally from a connecting portion 5112 opposite the gap 5C toward the gap 5C and having a generally "I"-shaped structure. The connecting portion 5112 of the laterally extending connecting portion 5113 is perpendicular to the connecting portion 5113, and the two are arranged in a generally "T" shape. The connecting portion 5112 of the laterally extending connecting portion 5113 is located between two adjacent peripheral electrode units 510A, or between a peripheral electrode unit 510A and an adjacent central electrode unit 510B, or between two adjacent central electrode units 510B. In other words, the connecting portion 5112 of the laterally extending connecting portion 5113 connects two adjacent peripheral electrode units 510A, or connects two adjacent central electrode units 510B, or connects a peripheral electrode unit 510A and an adjacent central electrode unit 510B. The connection portion 5113 can also be arranged in a "T" shape, and be arranged between two connection portions 5112 respectively connected to two central electrode units 510B arranged in a disconnected state, or be arranged between two connection portions 5112 respectively connected to a central electrode unit 510B arranged in a disconnected state and a peripheral electrode unit 510A adjacent to the central electrode unit 510B.

[0141] In other embodiments, at least two adjacent peripheral electrode units 510A among the plurality of peripheral electrode units 510A are arranged in a disconnected configuration, and at least one of the disconnected peripheral electrode units 510A is connected to a central electrode unit 510B located in an adjacent row and column and arranged diagonally therewith via a connecting portion 5112. That is, some adjacent peripheral electrode units 510A are connected via a connecting portion 5112; some adjacent peripheral electrode units 510A are arranged in a disconnected configuration without a connecting portion 5112 therebetween; and the connecting portion 5112 is provided between a peripheral electrode unit 510A and a central electrode unit 510B located in an adjacent row and column and arranged diagonally therewith, between two adjacent peripheral electrode units 510A, between two adjacent central electrode units 510B, or between a peripheral electrode unit 510A and an adjacent central electrode unit 510B located in the same row or column.

[0142] In this embodiment, the electrode unit 510 in the second row, third column is disconnected from the electrode unit 510 in the second row, fourth column, with a gap 5C formed between them. The electrode unit 510 in the third row, third column is disconnected from the electrode unit 510 in the third row, fourth column, with a gap 5C formed between them. The connecting portion 5113 is arranged in a "T" shape, spanning between the connecting portion 5112 in the middle of the third column and the connecting portion 5112 in the middle of the fourth column. The connecting portion 5112 in the middle of the third column is located between the two electrode units 510 in the second row of the third column and the fourth row of the third column. The connecting portion 5112 in the middle of the fourth column is located between the two electrode units 510 in the second row of the fourth column and the third row of the fourth column. The connecting portion 5112 is located between the two electrode units 510 in the second row of the fourth column and the third row of the fourth column. The connecting portion 5112 is located between all adjacent electrode units 510 in the same row or column, except for the two electrode units 510 in the second row, third column and the second row, fourth column, and the two electrode units 510 in the third row, third column and the third row, fourth column.

[0143] The electrode patch 500 forms multiple first open spaces 518 between multiple electrode units 510 and each connecting part 5112. The support member 53 and the adhesive member 55 extend into the corresponding first open spaces 518 and cover part of the corresponding first open spaces 518 to form a second open space 519. The second open space 519 allows the patient's skin to breathe freely and dissipate heat. As described in several previous embodiments, the spacing between adjacent adhesive members 55 affects the effective ventilation area of the first open space 518. Therefore, the following dimensional design approach is recommended for the adhesive members 55 and the support member 53: the width of the support member 53 is 1-8 mm larger than the diameter of the dielectric element 513, and the flat width of the adhesive member 55 is 2-14 mm longer than the width of the support member 53. Considering that the edge of the adhesive member 55 covers the side end surface of the support member 53 (with a thickness of 1 mm), the width of the adhesive member 55 after covering the support member 53 is 0-12 mm larger than the width of the support member 53. In other words, the adhesive member 55 partially extends into the first open space 518 by 0.5-10 mm along its width. In this embodiment, the diameter of the dielectric element 513 is 20 mm, the width of the support member 53 is 25 mm, and the width of the adhesive member 55 is 27-29 mm. In this embodiment, the row spacing between two adjacent dielectric elements 513 is 16 mm, the spacing between two adjacent support members 43 is 11 mm, the spacing between two adjacent adhesive members 55 is 9 mm, and the column spacing between two adhesive members 55 spaced apart in the same row is 16 mm.

[0144] When the electrode patch 500 is in use, most of the first open space 518 is ventilated and dissipated outward through the fully open second open space 519 located between adjacent adhesive members 55. The portion of the first open space 518 covered by the support member 53 and adhesive member 55 absorbs moisture through the support member 53 and adhesive member 55. During tumor electric field therapy, heat accumulated on the patient's skin surface where the electrode patch 500 is applied and moisture generated by sweat are discharged into the ambient air, preventing skin discomfort symptoms such as erythema, itching, follicular inflammation, pain, and papules.

[0145] Sixth embodiment of the electrode patch

[0146] refer to Figures 27 and 28 As shown, the electrode patch 600 of this embodiment includes a backing 62, an electrical functional component 61 adhered to the backing 62, two adhesive members 65 covering the electrical functional component 61, and a wire (not shown) electrically connected to the electrical functional component 61. The electrical functional component 61 includes a flexible circuit board 611 and a polymer dielectric layer 612 covering the flexible circuit board 611. The function of the polymer dielectric layer 612 is similar to the multiple dielectric elements in the previous embodiments. The polymer dielectric layer 612 includes a plurality of dielectric portions. In this embodiment, the polymer dielectric layer 612 is in the shape of a flower, and each petal is a dielectric portion 613. The plurality of dielectric portions 613 are arranged in a radially radiating shape. The multiple dielectric portions 613 are electrically connected through the flexible circuit board 611 to ensure that they can all receive AC signals. The two adhesive members 65 are arranged at intervals. As a simple transformation, the two adhesive members 65 can also be connected as one. The shape of the two adhesive members 65 is consistent with the shape of the polymer dielectric layer 612 and can completely cover the polymer dielectric layer 612. The adhesive members 65 are correspondingly provided with adhesive parts 651 covering each dielectric part 613.

[0147] A plurality of first open spaces 618 are formed between the multiple dielectric portions 613. The edges of the adhesive portions 651 extend into these first open spaces 618 and are directly adhered to the backing 62, increasing the stability of the adhesive member 65. However, the adhesive portions 651 occupy the highly effective ventilation area of the first open spaces 618. Therefore, a dimensional design approach is recommended for the adhesive member 65: the distance the edges of the adhesive portions 651 extend into the first open spaces 618 is 0.5-10 mm, preferably 0.5-6 mm, and more preferably 0.5-1 mm. Due to the lack of support, this dimension is slightly smaller than the corresponding dimensions in the previous embodiments. The adhesive portions 651 are slightly larger than the dielectric portions 613. After fully covering the dielectric portions 613, the excess portion extends into and partially covers the first open spaces 618. The portion of the first open spaces 618 not covered by the adhesive portions 651 forms a second open space 619 located between adjacent adhesive portions 651, allowing the patient's skin to breathe freely and dissipate heat. When the electrode patch 600 is in use, the second open space 619 allows the heat accumulated on the skin surface corresponding to the patient's electrode patch 600 and the water vapor generated by sweating to be discharged into the outside air. The part of the first open space 618 covered by the adhesive part 651 can absorb moisture through the adhesive part 651, thereby avoiding skin erythema, itching, follicle inflammation, pain, papules and other skin discomfort symptoms.

[0148] The above is only a preferred embodiment of the present application and is not intended to limit the present application.
