Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular, to an electrode patch and a tumor electrotherapy system. Background Art

[0002] The tumor electrotherapy system is a portable non-invasive device. By attaching an electrode patch to the human epidermis, a low-intensity, medium-frequency alternating electric field is applied to the human body for clinical treatment of various solid tumors. The alternating electric field with a specific frequency can interfere with and disrupt the mitosis of tumor cells, inhibit the proliferation of tumor cells, and achieve the tumor treatment effect. The electrode patch needs to be attached to the human body surface for a long time. A temperature chip is set in the center of the dielectric element that generates the electric field to monitor the temperature changes at these positions in real time during the treatment process. If there is an abnormal temperature, the treatment can be stopped immediately to avoid scalding the patient or treatment failure.

[0003] According to the location of the tumor, the size of the tumor, and the physical differences of the patient, the electrode patch needs to include multiple electrode units for combined use to meet the requirements of the treatment range and treatment intensity. The electrode patch needs to be attached to the human skin for a long time, and appropriate space for heat dissipation and ventilation needs to be left between the electrode units to avoid skin itching and allergic problems caused by excessive humidity and heat in the skin area covered by the electrode patch. The multiple electrode unit arrays of the existing electrode patches are all arranged in a horizontal (row) and vertical (column) grid pattern, as Figure 1 shown, resulting in an excessive density of electrode units that cannot adapt to the attachment positions of different body parts, and increasing the number of connection parts between the electrode units, with too small an open space, reducing the adhesion and air permeability of the electrode patch; and the lead-out rod is arranged on the connection part, and the flexible connection part has insufficient strength, which is easy to cause torsion, making the electrode patch not stick firmly; some even penetrate the mesh structure inside the electrode patch. This design not only makes the electrode patch not stick firmly, but also causes an obvious sense of compression on the skin. To solve the above problems, a design scheme of an electrode patch is proposed in the present invention. Summary of the Invention

[0004] The purpose of the present invention is to provide an electrode patch and a tumor electrotherapy system. By connecting multiple electrode units in series in space, the multiple electrode units after series connection form a large closed-loop structure with an irregular shape in space, and the closed-loop structure is in the shape of a wing that conforms to ergonomics, so that the electrode patch has better air permeability, is attached more firmly, can effectively transmit uniform electric field energy, and avoids energy loss.

[0005] To achieve the above object, in a first aspect, the present invention provides an electrode patch, including a patch portion for fitting with a patient's body to generate an alternating electric field; the patch portion includes a non-woven fabric with adhesiveness on one side, a plurality of electrode units fixed on the adhesive side of the non-woven fabric, the plurality of electrode units are connected in series through a connecting portion, and the plurality of electrode units after being connected in series form a closed-loop structure in space, and the closed-loop structure is a wing shape conforming to ergonomics; the patch portion further includes an outlet rod connected to an electrode unit, and the outlet rod extends outward from the edge of the wing-shaped structure.

[0006] Optionally, an electrode unit connected to the outlet rod is recessed at a position within the enclosed area formed by the plurality of electrode units. Such a design can, on the one hand, reduce the area of the flexible circuit board and save costs, and on the other hand, ensure that the wire led out by the outlet rod will not be attached to the human body, so it is more comfortable during application and provides a better user experience.

[0007] Optionally, the electrode patch further includes a wire portion, one end of the wire portion is connected to the outlet rod of the patch portion, and the other end of the wire portion is electrically connected to a signal generator through a connector.

[0008] Optionally, the arrangement of the plurality of electrode units is non-grid-shaped. Compared with the existing grid-shaped array arrangement, the electrode patch provided by the present invention has stronger air permeability, and the expandable wing-shaped structure is more in line with ergonomics. In this way, when the electrode patch is applied, it can adapt to different body parts and ensure a more secure application.

[0009] Optionally, the electrode patch further includes an expansion unit connected to the closed-loop structure, and the expansion unit includes a plurality of electrode units, which can be expanded according to the change of the tumor distribution area in the human body for treatment, and the design is simple and easy to implement to achieve full treatment of the patient's diseased part.

[0010] Optionally, the electrode unit includes a flexible circuit board, a temperature chip, and a circular dielectric element;

[0011] The flexible circuit board includes a circular reinforcing plate, the temperature chip is provided in the middle of the circular reinforcing plate, and pads surrounding the temperature chip are also provided on the circular reinforcing plate. Among them, the circular dielectric element is connected to the circular reinforcing plate through the pads, and the temperature chip is exposed in the through hole in the middle of the circular dielectric element.

[0012] In a second aspect, the present invention further provides an assembly method for an electrode patch, used for assembling the electrode patch as described above, including the following steps:

[0013] A flexible circuit board is manufactured, wherein the flexible circuit board is provided with a plurality of circular reinforcing plates and a plurality of connecting portions, wherein the circular reinforcing plates are connected in series to form a closed loop structure in space, and the closed loop structure is an ergonomic wing shape;

[0014] A temperature chip is welded in the middle of each circular reinforcement plate, and a circular dielectric element is welded through the welding pad on the circular reinforcement plate. The temperature chip is exposed in the through hole in the middle of the circular dielectric element. The circular reinforcement plate, temperature chip and circular dielectric element constitute an electrode unit; a flexible circuit board including multiple electrode units is adhered to a non-woven fabric; a positioning ring is set outside the circular dielectric element, and the positioning ring is adhered to the non-woven fabric together, and the outlet rod is pressed; gel is covered on one side surface of the circular dielectric element, and the gel is adhered to the positioning ring.

[0015] In a third aspect, the present invention provides a tumor electric field therapy system, comprising a signal generator, an adapter, and the electrode patch, wherein the electrode patch is electrically connected to the signal generator via the adapter.

[0016] The beneficial effects of the present invention are as follows:

[0017] In the present invention, after the multiple electrode units are connected in series, they form a closed-loop structure in space. The closed-loop structure is wing-shaped and conforms to ergonomics. This arrangement allows the electrode patch to be more firmly attached to the body surface, thereby being able to more effectively transmit uniform electric field energy and avoid energy loss. For example, the wing shape allows the electrode patch to be better attached to the upper chest, back, abdominal cavity, and triangular area on the upper edge of the abdominal cavity of the human body. In addition, the outlet rods in the present invention extend outward from the edge of the wing-shaped structure, and the outlet rods do not pass through the enclosed area. This arrangement can not only prevent the application process of the electrode patch from being affected by the outlet rods, but also make the enclosed area larger, making the application process more flexible, reducing the friction between the electrode patch and the body, and improving comfort. At the same time, the enclosed area can achieve better heat dissipation, ventilation, and application.

[0018] Furthermore, in the present invention, the lead-out rod is connected to the electrode unit rather than the connecting part. This arrangement can prevent the lead-out rod from twisting relative to the non-woven fabric, avoiding pulling on the electrode patch and making the electrode patch adhere more firmly. At the same time, it can reduce the possibility of damage to the lead-out rod. Moreover, in the present invention, adjacent electrode units are connected by connecting parts, and the connected multiple electrode units form an ergonomic wing-like structure in space. This enables the multiple electrode units to form a divergent non-grid array arrangement, reducing the number of connecting parts, saving the cost of the flexible circuit board. At the same time, the reduction of the connecting parts increases the application space, improves the air circulation ability, enhances the breathability, and improves the user experience. In addition, the non-grid array arrangement makes the overall structure more elastic and better able to adapt to the unevenness and stretching deformation of various parts of the human body.

[0040] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art in the field to which the present invention belongs. The words such as "including" used herein mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects.

[0041] In view of the problems existing in the prior art, the embodiments of the present invention provide an electrode patch, including a patch part 100 for fitting with a patient's body to generate an alternating electric field, as Figure 2 shown. The patch part 100 includes a non-woven fabric 5 with adhesiveness on one side, and a plurality of electrode units 1 fixed on the adhesive side of the non-woven fabric 5. Adjacent electrode units 1 are connected in series through a connection part 2. Among them, the plurality of electrode units 1 after being connected in series form a closed-loop structure in space, and this closed-loop structure is a wing shape that conforms to ergonomics. As Figure 2 shown, the geometric shape formed by three adjacent electrode units is a V shape. For example, Figure 2 the geometric shape formed by three electrode units in the elliptical dotted line frame is a V shape. From Figure 2It can be seen that multiple electrode units 1 are connected in series to form multiple V shapes. Since the spatial distances between all electrode units are basically the same, when the electrode patch is applied to the human body, a uniform electric field can be generated. Moreover, due to the relatively stable characteristics of the V-shaped geometry in space, the electrode patch can be more firmly attached during application, and thus can more effectively transfer the electric field energy and avoid energy loss.

[0042] It should be understood that during use, a pair of electrode patches are applied to the patient's body to form an electric field. The electric field passes through the diseased cancer cells, interferes with the division of cancer cells, and inhibits the proliferation of cancer cells, thereby achieving the purpose of treatment. The application method depends on the body part. Specifically, a pair of the electrode patches are arranged opposite to each other front and back on the human body. For example, when treating abdominal diseased cancer cells, one electrode patch can be applied to the abdomen and the other to the back respectively. Another example is that when treating brain diseased cancer cells, one electrode patch can be applied to the front and back parts of the brain respectively.

[0043] In this embodiment, the patch part 100 further includes an outgoing wire rod 3 connected to one electrode unit 1. The outgoing wire rod 3 extends outward from the edge of the wing-shaped structure, and one electrode unit 1 connected to the outgoing wire rod 3 is recessed at a position within the enclosed area 4 formed by the multiple electrode units 1. Such a design can, on the one hand, reduce the area of the flexible circuit board and save costs, and on the other hand, prevent the wire led out by the outgoing wire rod 3 from being applied to the human body, so it is more comfortable during application and the user experience is better. The outgoing wire rod 3 is connected to the electrode unit 1 rather than the connecting part 2. This setting can prevent the outgoing wire rod 3 from twisting relative to the non-woven fabric 5, causing pulling on the electrode patch and making the electrode patch more firmly attached.

[0044] In an optional embodiment, the closed-loop structure can be formed by 8 electrode units, as Figure 3A shown. The 8 electrode units form a symmetric wing shape, including a left wing M and a right wing N. Since the human body is symmetric, in this embodiment, the left wing and the right wing are symmetrically arranged, which can make the electrode patch more in line with the ergonomic structure and make the application process of the electrode patch more flexible and firm. In this configuration, one of the electrode units 1 is located at the midline of the left wing and the right wing and is recessed at a position within the enclosed area 4. The geometric shape formed by three adjacent electrode units in the closed-loop structure is V-shaped. The electrode unit 1 forms a V shape with the two adjacent electrode units 1, and the electrode unit 1 recessed at a position within the enclosed area 4 serves as the bottom of the V-shaped structure. The outgoing wire rod 3 is connected to the electrode unit 1 at the bottom of the V-shaped structure, and the outgoing wire rod 3 extends outward from the electrode unit 1 at the bottom of the V-shaped structure to the outside of the enclosed area 4, avoiding pulling on the connecting part 2 and not occupying the internal application and heat dissipation and ventilation space of the electrode patch.

[0045] Another optional embodiment is that eight electrode units form a wing shape as shown in Figure 3B shown, Figure 3B the configuration is as shown in Figure 3A In a consistent configuration, one of the electrode units 1 is recessed at the position of the enclosing region 4 and forms a V-shaped structure. However, in Figure 3B this configuration, the lead-out rod 3 is connected to one of the electrode units 1 at the opening edge of the V-shaped structure.

[0046] In an optional embodiment, the closed-loop structure may be formed by ten electrode units, as shown in Figure 4A shown. Ten electrode units form a symmetrical wing shape. In this configuration, ten electrode units 1 form an enclosing region 4. One of the electrode units 1 is recessed at the position of the enclosing region 4. This electrode unit 1 and two adjacent electrode units 1 form a V-shaped structure. The lead-out rod 3 is connected to the electrode unit 1 at the bottom of the V-shaped structure, and the lead-out rod 3 extends outward from the connected electrode unit 1 to the outside of the enclosing region 4.

[0047] Another optional embodiment is that ten electrode units form a wing shape as shown in Figure 4B shown. This configuration is derived from the configuration shown in Figure 3B by forming an expansion unit 9. As shown in Figure 4B the square dotted line frame in encloses the expansion unit 9. In the configuration shown in Figure 4B two expansion units 9 are derived. Each expansion unit 9 includes an electrode unit 1 connected through the connecting portion 2. The setting of this expansion unit 9 can be expanded according to the change of the tumor distribution area of the human body for treatment. Specifically, according to actual needs, multiple expansion units 9 can be expanded on the same wing-shaped structure, or multiple electrode units 1 can be expanded in each expansion unit 9 to cope with the application on various parts of the human body.

[0048] In an optional embodiment, the closed-loop structure may be formed by twelve electrode units, as shown in Figure 5 shown. This configuration is derived from the configuration shown in Figure 4A by forming an expansion unit 9. In the configuration of Figure 4, the number of expansion units 9 and the number of electrode units 1 in each expansion unit 9 can both be expanded to cope with the application on various parts of the human body, which will not be elaborated here.

[0049] In an optional embodiment, the closed-loop structure may be formed by twenty electrode units, as shown in Figure 6 shown. The configuration of the twenty-unit wing-shaped structure is based on the configuration shown in Figure 4BIt is formed by extending and expanding unit 9 based on the configuration, and in this configuration, the extending unit 9 is Figure 4B consistent with the configuration. In this configuration, the number of the outgoing wires 3 is set to one. Of course, in order to cope with the application on various parts of the human body, the number of the extending units 9 and the number of the electrode units 1 in each extending unit 9 can be expanded, which will not be elaborated here.

[0050] It should be noted that Figure 3A 、 3B 、4A, 4B, Figure 5 and Figure 6 in the configuration, the geometric shape formed by three adjacent electrode units in each configuration is V-shaped. Since the triangular structure is the most stable structure among all structures and has the best supportability, in the above several configurations, the connecting part 2 is not easily deformed and the electrode unit 1 is not easily displaced. The electrode unit 1 is in a local triangular layout. Compared with the determinant layout, there are fewer connecting parts 2, which increases the adhesive area, has a greater application force, reduces the probability of falling off, enables the patient to have a better treatment effect, and the reduction of the connecting part 2 increases the application space, has better air circulation ability, increases the air permeability, and reduces the adverse impact on the user's skin. The geometric shape formed by three adjacent electrode units is V-shaped, which makes the distance between the electrode units 1 more uniform, the electric field applied to the treatment area of the tumor can also be more uniform, and the applied range is larger. Compared with the existing determinant layout, for the same treatment area, only fewer electrode units 1 can achieve the same treatment effect. By reducing the number of the electrode units 1, the production cost can be effectively reduced. The geometric shape formed by three adjacent electrode units is V-shaped, which makes the electrode units on the entire electrode patch have more V-shaped structures. The outgoing wire 3 is led out from the electrode unit 1 at the bottom of the V-shaped structure, and the outgoing wire 3 is directly connected to the circular reinforcement plate 111 (to be described in detail later). In this way, the outgoing wire 3 has enough distance from the circular reinforcement plate 111 to the outer edge of the flexible circuit board, will not increase the maximum edge of the flexible circuit board, thereby reducing the production cost. At the same time, the outgoing wire 3 is directly connected to the circular reinforcement plate 111, so it has better strength, is not easily torn or twisted, and reduces the possibility of the outgoing wire 3 failing.

[0051] In an embodiment, the electrode patch further includes a wire part 6. As Figure 2 shown, one end of the wire part 6 is connected to the outgoing wire 3 of the patch part 100, and the other end of the wire part 6 is electrically connected to the signal generator 8 through a connector.

[0052] In one embodiment, the arrangement of multiple electrode units in the electrode patch is non-grid-shaped. Compared with the existing grid-shaped array arrangement, the electrode patch provided by the present invention has better air permeability and is more ergonomic. In this way, when the electrode patch is applied, it can be applied more firmly, and at the same time, it can ensure a more secure application.

[0053] In one embodiment, the electrode unit 1 includes a flexible circuit board 11, a temperature chip 12, and a circular dielectric element 13, as Figure 7 shown. The flexible circuit board 11 is provided with a circular reinforcing plate 111. The temperature chip 12 is provided in the middle of the circular reinforcing plate 111. The circular reinforcing plate 111 is also provided with pads surrounding the temperature chip 12. Among them, the circular dielectric element 13 is connected to the circular reinforcing plate 111 through the pads, and the temperature chip 12 is exposed in the through hole in the middle of the circular dielectric element 13.

[0054] In one embodiment, the circular reinforcing plate 111 is provided with a plurality of via pads 14, as Figure 8 shown. The via pads 14 are adjacent to the pins of the temperature chip 12. Preferably, an insulating paint 15 is covered outside the via pads 14 to prevent the via pads 14 from short-circuiting with the pins of the temperature chip 12.

[0055] Because in the prior art, when the circular dielectric element 13 and the circular reinforcing plate 111 are welded, it is difficult to accurately locate, and it is not easy to detect eccentricity, resulting in contact short-circuit failure between the through-hole wall of the circular dielectric element 13 and the pins of the temperature chip 12. In this embodiment, a welding indication ring (not labeled) is provided on the circular reinforcing plate 111, as Figure 9 shown. The welding indication ring surrounds the pins of the temperature chip 12 and is used to indicate the safe distance between the through-hole wall and the pins of the temperature chip 12. Among them, the welding indication ring is provided between the via pads 14 and the pins of the temperature chip 12, or outside the via pads 14 to enclose the via pads 14 and the pins of the temperature chip 12.

[0056] It should be understood that the setting of the welding indication ring can form a blocking structure outside the temperature chip 12. The setting of this blocking structure makes the through-hole wall have a safe distance from the pins of the temperature chip 12 when the circular dielectric element 13 is eccentric relative to the circular reinforcing plate 111 during the welding process, avoiding contact between the circular dielectric element 13 and the pins of the temperature chip 12, and thus effectively preventing the occurrence of short-circuit failure.

[0057] Exemplarily, the welding indication ring is disposed between the via pad 14 and the pin of the temperature chip 12. At this time, both the welding indication ring and the via pad 14 are exposed in the through hole. Such a setting allows for direct observation of the installation positions of the circular dielectric element 13 and the circular reinforcing plate 111 through the through hole. Of course, this example setting can also achieve an insulating effect, and cooperate with the insulating coating to make the insulation performance between the via pad 14 and the pin of the temperature chip 12 better.

[0058] In one embodiment, the electrode unit 1 further includes a positioning line 16 disposed on the circular reinforcing plate 111, as Figure 9 shown. Among them, the positioning line 16 includes a plurality of straight line segments arranged radially along the circular reinforcing plate 111 to indicate the installation positions of the circular reinforcing plate 111 and the circular dielectric element 13 through the plurality of straight line segments.

[0059] Specifically, the positioning line 16 draws an installation area on the circular reinforcing plate 111. Aligning the circular dielectric element 13 with the edge of the installation area can prevent the circular dielectric element 13 and the circular reinforcing plate 111 from being eccentric during installation.

[0060] In other embodiments, a plurality of scale lines are arranged radially along the circular reinforcing plate 111 on the straight line. Through the scale lines, the circular dielectric elements 13 of different sizes can be accurately positioned.

[0061] The present invention also provides an assembly method for the electrode patch, which is used for the assembly of the electrode patch as Figure 10 shown, and includes the following steps:

[0062] S01: Fabricate the flexible circuit board 11. The flexible circuit board 11 is provided with a plurality of circular reinforcing plates 111 and a plurality of connecting parts 2. The circular reinforcing plates after being connected in series form a closed-loop structure in space, and the closed-loop structure is a wing shape conforming to ergonomics.

[0063] In this step, the flexible circuit board 11 with a wing shape conforming to ergonomics in space is fabricated first. Based on this positioning, other components of the electrode patch are installed, and finally the arrangement of the electrode unit 1 on the electrode patch forms a wing shape conforming to ergonomics in space.

[0064] S02: Weld a temperature chip 12 in the middle of each circular reinforcing plate 111, and weld a circular dielectric element 13 through the pads on the circular reinforcing plate 111. The temperature chip 12 is exposed in the through hole in the middle of the circular dielectric element 13. The circular reinforcing plate 111, the temperature chip 12, and the circular dielectric element 13 form an electrode unit 1.

[0065] This step is for the installation of the electrode unit 1, and through this step, the installation process of the electrode unit 1 can be made more efficient and convenient.

[0066] S03: Paste the flexible circuit board 11 including a plurality of the electrode units 1 on the non-woven fabric 5.

[0067] In this step, one side of the non-woven fabric 5 has adhesiveness and the other side does not. The electrode unit 1 is fixed to the adhesive side of the non-woven fabric 5.

[0068] S04: Set the positioning ring 17 outside the circular dielectric element 13, paste the positioning ring 17 together with the non-woven fabric 5, and press down on the lead-out rod 3.

[0069] In this step, the positioning ring 17 is arranged outside the circular dielectric element 13. The positioning ring 17 can play a heat insulation role, achieving the effect of protecting the body and preventing the high-temperature circular dielectric element 13 from scalding the human body; one side of the positioning ring 17 has adhesiveness and the other side does not, and the adhesive side of the positioning ring 17 is connected to the non-woven fabric 5.

[0070] S05: Cover the surface of the circular dielectric element 13 with the gel 18, and the gel 18 is pasted to the positioning ring 17.

[0071] In this step, both sides of the gel 18 have adhesiveness. The gel 18 covers the circular dielectric element 13 and the positioning ring 17, thus completing the installation of the electrode patch.

[0072] The present invention also provides a tumor electric field treatment system, as Figure 11 shown, including a signal generator 8, the electrode patch described above, and a adapter 7 electrically connected to the signal generator 8. The electrode patch is electrically connected to the signal generator 8 through the adapter 7.

[0073] In summary, in the present invention, a plurality of the electrode units 1 are arranged in a wing-shaped structure that conforms to ergonomics. Such a setting enables the electrode patch to be more firmly attached to the body surface, thereby being able to more effectively transmit electric field energy and avoid energy loss. For example, the formation of the wing-shaped structure enables the electrode patch to better adhere to the head, upper chest, back, abdominal cavity, and the triangular area along the upper edge of the abdominal cavity of the human body, etc.

[0074] In the present invention, the lead-out rod 3 extends outward from the edge of the wing-shaped structure, and the lead-out rod 3 does not pass through the enclosed area. Such a setting can not only ensure that the application process of the electrode patch is not affected by the lead-out rod 3, but also make the enclosed area larger, making the fitting process more flexible, reducing the friction between the electrode patch and the body, improving the comfort. At the same time, the enclosed area can achieve better heat dissipation, ventilation and application.

[0075] In the present invention, the lead-out rod 3 is connected to the electrode unit 1 instead of the connecting part 2. Such a setting can prevent the lead-out rod 3 from twisting relative to the non-woven fabric 5, causing pulling on the electrode patch, making the electrode patch adhere more firmly, and at the same time reducing the possibility of damage to the lead-out rod.

[0076] In the present invention, the adjacent electrode units 1 are connected by the connecting part 2, and the connected multiple electrode units 1 form a wing-shaped structure that conforms to ergonomics in space. In this way, the multiple electrode units 1 form a divergent non-grid array arrangement, reducing the number of connecting parts, saving the cost of the flexible circuit board 11. At the same time, the reduction of the connecting parts increases the application space, has better air circulation ability, increases the breathability, improves the user experience, and the non-grid array arrangement makes the overall structure more elastic and more adaptable to the unevenness and stretching deformation of various parts of the human body.

[0077] Although the embodiments of the present invention have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present invention described in the claims. Moreover, the present invention described herein can have other embodiments and can be implemented or realized in various ways.
