Description

Technical Field

[0001] The present disclosure relates to the technical field of electric field therapy, and particularly to an electric field therapy system. Background Art

[0002] The principle of electric field therapy is to act on the tubulin of proliferating cancer cells through low-intensity, medium-frequency alternating electric fields, interfere with the mitosis of tumor cells, cause the affected cancer cells to apoptosis and inhibit tumor growth. With the local application mode and anti-mitotic effect, compared with traditional treatment methods such as surgery, radiotherapy and drug therapy, electric field therapy is widely used due to its advantages such as small side effects and good inhibition effect.

[0003] Currently, the device based on electric field therapy uses a relatively large number of electrodes to form a treatment current to inhibit tumors at the target site by using the treatment current. However, since the treatment areas of multiple electrodes are fixed, and they are uniformly controlled and energized and cannot operate independently, the direction of the treatment current is single, the quantity is limited, and the ineffective treatment area is large. This not only limits the treatment effect, but also causes a lot of electric field waste. At the same time, when the temperature of a certain electrode is too high, multiple electrodes need to stop discharging simultaneously, resulting in a shortened overall treatment time and it is difficult to ensure a good treatment effect.

[0028] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, an electric field therapy system is proposed in an embodiment of the present disclosure, which includes a plurality of electrodes 1, a power supply module 2, and a control module 3. The plurality of electrodes 1 are arranged at intervals in sequence on the target site. The power supply ends of the power supply module 2 are respectively connected to the power supply ends of the plurality of electrodes 1. The control module 3 is configured to control the power supply module 2 to send signals with opposite polarities to the electrodes 1 in the first arbitrary region 4 and the electrodes 1 in the second arbitrary region 5 on the target site, so as to generate a therapeutic current 6 between the electrodes 1 in the first arbitrary region 4 and the electrodes 1 in the second arbitrary region 5.

[0030] It can be understood that since the power supply ends of the power supply module 2 are respectively connected to the power supply ends of the plurality of electrodes 1, and under the control of the control module 3, the power supply module 2 can send signals with opposite polarities to the electrodes 1 in the first arbitrary region 4 and the electrodes 1 in the second arbitrary region 5 on the target site, thereby generating a therapeutic current 6 between the electrodes 1 in the first arbitrary region 4 and the electrodes 1 in the second arbitrary region 5, meeting the tumor treatment requirements.

[0031] Among them, since the power supply module 2 can send signals with opposite polarities to the electrodes 1 in two arbitrary regions, each electrode 1 in the electric field therapy system can be independently controlled and independently powered on. It can not only generate therapeutic currents 6 in any direction and any quantity on the target site to meet the tumor suppression requirements in different positions and different directions, but also can realize the concentrated arrangement of the electric field, avoiding the waste of the electric field, thereby effectively improving the tumor suppression effect. At the same time, when the temperature of a certain electrode 1 is too high, only the discharge of this electrode 1 can be stopped, and it does not affect the operation of other electrodes 1, thereby effectively increasing the overall treatment time and ensuring a better treatment effect of the electric field therapy system on the target site.

[0032] It should be noted that in related embodiments, the direction of the therapeutic current 6 is single and the treatment area is fixed. However, research shows that the direction of the therapeutic current 6 and the direction of tumor mitosis need to form a set angle to achieve the best treatment effect. Therefore, in the electric field therapy system of this embodiment, the arbitrarily set direction of the therapeutic current 6 and the treatment area can flexibly adapt to tumors in different positions and different directions of mitosis on the target site, thereby effectively improving the tumor suppression effect.

[0033] Moreover, the method of using the therapeutic current 6 to suppress tumors requires more than a certain period of time to ensure a better treatment effect, generally more than 18 hours. However, long-term operation will cause the electrodes 1 to overheat. When reaching the set threshold, the operation of the electrodes 1 needs to be stopped to avoid damaging the target site. In related embodiments, since the plurality of electrodes 1 are uniformly controlled and uniformly powered on, when the temperature of a certain electrode 1 is too high, the discharges of the plurality of electrodes 1 need to be stopped simultaneously. In the electric field therapy system of this embodiment, independent power-off of a single electrode 1 can be realized, thereby avoiding affecting the operation of other electrodes 1 and ensuring a long overall treatment time.

[0034] Meanwhile, in related embodiments, multiple electrodes 1 are controlled and powered uniformly, and the switching between the directions of multiple treatment currents 6 is also controlled orderly. However, research has shown that the disordered switching between the directions of multiple treatment currents 6 has a better treatment effect than the orderly switching. Therefore, in the electric field treatment system of the present embodiment, since each electrode 1 can operate independently, it is conducive to realizing the disordered switching between the directions of the treatment current 6 as a whole, thereby making the whole have a better tumor suppression effect.

[0035] The target site is a site with a tumor, which can be the head, limbs, abdomen, chest, etc. of the human body, and there is no limitation thereto.

[0036] The electrode 1 is used to generate a treatment current 6 on the target site. Among them, when the signal polarities of the electrodes 1 in the first arbitrary region 4 and the second arbitrary region 5 are opposite, a conductive loop can be formed between the electrodes 1 in the first arbitrary region 4 and the electrodes 1 in the second arbitrary region 5 by using the conductivity of the target site, and the part of the conductive loop in the target site forms a treatment current 6. The specific type of the electrode 1 can be set according to actual needs, and there is no limitation thereto.

[0037] Both the first arbitrary region 4 and the second arbitrary region 5 are arbitrary regions of the target site, which can be regular regions such as circular, rectangular, or rhombic, or other irregular regions, and there is no limitation thereto.

[0038] The number of electrodes 1 in the first arbitrary region 4 and the second arbitrary region 5 can be one or multiple, and there is no limitation thereto. For example, if there is one electrode 1 in the first arbitrary region 4 and one electrode 1 in the second arbitrary region 5, the treatment current 6 is generated by one electrode 1 in the first arbitrary region 4 and one electrode 1 in the second arbitrary region 5, and the current direction is from one electrode 1 in the first arbitrary region 4 to one electrode 1 in the second arbitrary region 5, or from one electrode 1 in the second arbitrary region 5 to one electrode 1 in the first arbitrary region 4; if there are multiple electrodes 1 in the first arbitrary region 4 and one electrode 1 in the second arbitrary region 5, the treatment current 6 is generated by multiple electrodes 1 in the first arbitrary region 4 and one electrode 1 in the second arbitrary region 5, and the current direction is from multiple electrodes 1 in the first arbitrary region 4 to one electrode 1 in the second arbitrary region 5, or from one electrode 1 in the second arbitrary region 5 to multiple electrodes 1 in the first arbitrary region 4; if there are multiple electrodes 1 in the first arbitrary region 4 and multiple electrodes 1 in the second arbitrary region 5, the treatment current 6 is generated by multiple electrodes 1 in the first arbitrary region 4 and multiple electrodes 1 in the second arbitrary region 5, and the current direction is from multiple electrodes 1 in the first arbitrary region 4 to multiple electrodes 1 in the second arbitrary region 5, or from multiple electrodes 1 in the second arbitrary region 5 to multiple electrodes 1 in the first arbitrary region 4.

[0039] The power supply module 2 is used to independently supply power to each electrode 1 under the control of the control module 3. The specific type of the power supply module 2 can be set according to actual needs, and there is no limitation on this. By way of example, the power supply module 2 can be an AC power supply.

[0040] The control module 3 is used to control the power supply path of each electrode 1 to realize the selection of any position of the electrode 1. The specific type of the control module 3 can be set according to actual needs, and there is no limitation on this.

[0041] As Figure 1 and Figure 2 shown, in some embodiments, the electric field therapy system further includes a plurality of first switches 7. The first switches 7 are connected in series between the first power supply terminal of the power supply module 2 and the power supply terminal of the electrode 1. The first end of the first switch 7 is connected to the first power supply terminal of the power supply module 2, the second end of the first switch 7 is connected to the power supply terminal of the electrode 1, and the input end of the first switch 7 is connected to the output end of the control module 3. Among them, the control module 3 is used to control the on / off of the plurality of first switches 7 so that the first power supply terminal of the power supply module 2 sends a positive signal or a negative signal to the electrode 1 in the first arbitrary area 4.

[0042] It can be understood that since the first end of the first switch 7 is connected to the first power supply terminal of the power supply module 2 and the second end of the first switch 7 is connected to the power supply terminal of the electrode 1, the first switch 7 can conduct or disconnect the path between the first power supply terminal of the power supply module 2 and the power supply terminal of the electrode 1 under the control of the control module 3. Thus, the independent control and independent power-on of each electrode 1 are realized by using the first switch 7. Not only can therapeutic currents 6 in any direction and any quantity be generated at the target site to meet the tumor suppression requirements in different positions and different directions, but also the centralized arrangement of the electric field can be realized to avoid the waste of the electric field, thereby effectively improving the tumor suppression effect. At the same time, when the temperature of a certain electrode 1 is too high, only the discharge of this electrode 1 can be stopped without affecting the operation of other electrodes 1, thereby effectively increasing the overall treatment time and ensuring a better treatment effect of the electric field therapy system on the target site.

[0043] It should be noted that the first switch 7 is used to control the on / off of the path between the first power supply terminal of the power supply module 2 and the power supply terminal of the electrode 1. The specific type of the first switch 7 can be set according to actual needs, and there is no limitation on this. By way of example, the first switch 7 can be an analog switch, such as: MOS (Metal - Oxide - Semiconductor Field - Effect Transistor, MOSFET, metal - oxide - semiconductor field - effect transistor) tube.

[0044] Under the condition that the power supply module 2 sends signals with opposite polarities to the electrode 1 in the first arbitrary region 4 and the electrode 1 in the second arbitrary region 5, the first power supply terminal of the power supply module 2 can send a positive signal to the electrode 1 in the first arbitrary region 4 by using the first switch 7, or can send a negative signal to the electrode 1 in the first arbitrary region 4 by using the first switch 7, and there is no limitation on this.

[0045] As Figure 1 and Figure 2 shown, in some embodiments, the electric field therapy system further includes a plurality of second switches 8. The second switches 8 are connected in series between the second power supply terminal of the power supply module 2 and the power supply terminal of the electrode 1. The first end of the second switch 8 is connected to the second power supply terminal of the power supply module 2, the second end of the second switch 8 is connected to the power supply terminal of the electrode 1, and the input end of the second switch 8 is connected to the output end of the control module 3. Among them, the control module 3 is used to control the on / off of the plurality of second switches 8, so that when the first power supply terminal of the power supply module 2 sends a positive signal to the electrode 1 in the first arbitrary region 4, the second power supply terminal of the power supply module 2 sends a negative signal to the electrode 1 in the second arbitrary region 5; when the first power supply terminal of the power supply module 2 sends a negative signal to the electrode 1 in the first arbitrary region 4, the second power supply terminal of the power supply module 2 sends a positive signal to the electrode 1 in the second arbitrary region 5.

[0046] It can be understood that since the first end of the second switch 8 is connected to the second power supply terminal of the power supply module 2 and the second end of the second switch 8 is connected to the power supply terminal of the electrode 1, the second switch 8 can conduct or disconnect the path between the second power supply terminal of the power supply module 2 and the power supply terminal of the electrode 1 under the control of the control module 3. Thus, by the cooperation of the first switch 7 and the second switch 8, independent control and independent power supply of each electrode 1 are realized. Not only can therapeutic currents 6 in any direction and any quantity be generated at the target site to meet the tumor suppression requirements in different positions and different directions, but also the concentrated arrangement of the electric field can be realized to avoid the waste of the electric field, thereby effectively improving the tumor suppression effect. At the same time, when the temperature of a certain electrode 1 is too high, only the discharge of this electrode 1 can be stopped without affecting the operation of other electrodes 1, thereby effectively increasing the overall treatment time and ensuring a better treatment effect of the electric field therapy system on the target site.

[0047] It should be noted that the second switch 8 is used to control the on / off of the path between the second power supply terminal of the power supply module 2 and the power supply terminal of the electrode 1. The specific type of the second switch 8 can be set according to actual needs, and there is no limitation on this. By way of example, the second switch 8 can be an analog switch, for example: a MOS transistor.

[0048] The numbers of the first switch 7 and the second switch 8 are the same as the number of the electrodes 1 respectively. Each first switch 7 and second switch 8 corresponds to each electrode 1. Thus, through the on-off cooperation of the first switch 7 and the second switch 8, the independent operation of each electrode 1 is realized. For example, when the first switch 7 of the electrode 1 in the first arbitrary region 4 is turned on and the second switch 8 is turned off, and the first switch 7 of the electrode 1 in the second arbitrary region 5 is turned off and the second switch 8 is turned on, the first power supply terminal of the power supply module 2 supplies power to the electrode 1 in the first arbitrary region 4, and the second power supply terminal of the power supply module 2 supplies power to the electrode 1 in the second arbitrary region 5. Thus, the signals of the electrode 1 in the first arbitrary region 4 and the signals of the electrode 1 in the second arbitrary region 5 have opposite polarities, and a therapeutic current 6 is generated between the electrode 1 in the first arbitrary region 4 and the electrode 1 in the second arbitrary region 5.

[0049] To meet the condition that the power supply module 2 sends signals with opposite polarities to the electrode 1 in the first arbitrary region 4 and the electrode 1 in the second arbitrary region 5, when the first power supply terminal of the power supply module 2 sends a positive signal to the electrode 1 in the first arbitrary region 4 by using the first switch 7, the second power supply terminal of the power supply module 2 sends a negative signal to the electrode 1 in the second arbitrary region 5 by using the second switch 8. On the contrary, when the first power supply terminal of the power supply module 2 sends a negative signal to the electrode 1 in the first arbitrary region 4 by using the first switch 7, the second power supply terminal of the power supply module 2 sends a positive signal to the electrode 1 in the second arbitrary region 5 by using the second switch 8.

[0050] As Figure 1 shown, in some embodiments, the electric field therapy system further includes a shift register 9. The shift register 9 is arranged between the output end of the control module 3 and the input ends of the first switch 7 and the second switch 8. The input end of the shift register 9 is connected to the output end of the control module 3, and the output ends of the shift register 9 are respectively connected to the input ends of the first switch 7 and the second switch 8.

[0051] It can be understood that since the input end of the shift register 9 is connected to the output end of the control module 3, and the output ends of the shift register 9 are respectively connected to the input ends of the first switch 7 and the second switch 8, the control module 3 can use the shift register 9 to send control signals to multiple first switches 7 and multiple second switches 8, so as to ensure that the electric field therapy system generates therapeutic currents 6 in any direction and any quantity at the target site. At the same time, the shift register 9 can convert the control signals sent by the control module 3 into parallel signals and uniformly assign them to all the first switches 7 and the second switches 8, so as to ensure that multiple electrodes 1 can act synchronously and stably generate therapeutic currents 6, and further ensure a better therapeutic effect of the electric field therapy system on the target site.

[0052] It should be noted that the shift register 9 is a flip-flop-based device that operates under several identical time pulses. The specific type of the shift register 9 can be set according to actual needs, and no restrictions are imposed on this.

[0053] In some embodiments, the control module 3 includes an MCU (Micro Controller Unit), the output end of the MCU is connected to the input end of the shift register 9, and the MCU is used to control the on / off states of multiple first switches 7 and multiple second switches 8, so that the power supply module 2 sends signals with opposite polarities to the electrodes 1 in the first arbitrary region 4 and the electrodes 1 in the second arbitrary region 5.

[0054] It can be understood that since the output end of the MCU is connected to the input end of the shift register 9, the MCU can use the shift register 9 to control the on / off states of multiple first switches 7 and multiple second switches 8, so that the power supply module 2 sends signals with opposite polarities to the electrodes 1 in the first arbitrary region 4 and the electrodes 1 in the second arbitrary region 5, thereby ensuring that the electric field therapy system generates therapeutic currents 6 in any direction and any number at the target site, meeting the tumor treatment requirements.

[0055] At the same time, the shift register 9 can convert the serial signal sent by the MCU into a parallel signal and uniformly assign it to all the first switches 7 and second switches 8, thereby ensuring that multiple electrodes 1 can act synchronously and stably generate therapeutic currents 6, and further ensuring a better therapeutic effect of the electric field therapy system on the target site.

[0056] It should be noted that the MCU appropriately reduces the frequency and specifications of the Central Process Unit (CPU), and integrates peripherals such as memory, Timer, USB (Universal Serial Bus), A (analog) / D (digital) conversion, and UART (Universal Asynchronous Receiver / Transmitter) on a single chip to form a chip-level computer for different combinations of control in different application scenarios. Among them, the specific type of the MCU can be set according to actual needs, and no restrictions are imposed on this.

[0057] Such as Figure 6As shown, in some embodiments, the electric field treatment system further includes a plurality of temperature sensors 10. The temperature sensors 10 are disposed close to the electrodes 1, and the output ends of the temperature sensors 10 are connected to the input end of the control module 3. Among them, the control module 3 is configured to disconnect the first switch 7 and the second switch 8 corresponding to the electrode 1 where the temperature sensor 10 is located when the temperature detected by the temperature sensor 10 is greater than the set threshold value.

[0058] It can be understood that since the temperature sensors 10 are disposed close to the electrodes 1 and the output ends of the temperature sensors 10 are connected to the input end of the control module 3, the temperature sensors 10 can detect the temperature of the electrodes 1 and send the detected temperature signals to the control module 3. Thus, when the temperature of the electrode 1 is greater than the set threshold value, the control module 3 can disconnect the first switch 7 and the second switch 8 corresponding to the electrode 1 where the temperature sensor 10 is located, thereby avoiding damage to the target site due to the too high temperature of the electrode 1.

[0059] At the same time, through the cooperation of the temperature sensors 10, the control module 3, the first switch 7 and the second switch 8, the path between the electrode 1 with too high temperature and the power supply module 2 can be accurately disconnected without affecting the operation of other electrodes 1, so as to ensure that the treatment time of the electric field treatment system for the target site can meet the treatment requirements, and further ensure a good treatment effect of the electric field treatment system on the target site.

[0060] It should be noted that the temperature sensors 10 are used to detect the temperature of the electrodes 1, and the specific type of the temperature sensors 10 can be set according to actual needs, and there is no limitation thereto. By way of example, the temperature sensors 10 can be thermistors.

[0061] The number of the temperature sensors 10 is the same as the number of the electrodes 1, and each electrode 1 corresponds to one temperature sensor 10.

[0062] The set threshold value can be set according to actual needs, and there is no limitation thereto. By way of example, the set threshold value can be 42 °C.

[0063] As Figure 6 shown, in some embodiments, the electrode 1 includes an FPC 101 (Flexible Printed Circuit) and a dielectric ceramic 102. The power supply end of the FPC 101 is connected to the power supply end of the power supply module 2, and the output end of the FPC 101 is connected to the input end of the control module 3. A plurality of FPCs 101 are connected in sequence to form a substrate. The dielectric ceramic 102 is disposed on the FPC 101, and the power supply end of the dielectric ceramic 102 is connected to the power supply end of the FPC 101. The side of the dielectric ceramic 102 away from the FPC 101 is arranged on the target site. The temperature sensor 10 is disposed close to the dielectric ceramic 102, and the output end of the temperature sensor 10 is connected to the input end of the FPC 101.

[0064] It can be understood that since the power supply terminal of the FPC 101 is connected to the power supply terminal of the power supply module 2, and the power supply terminal of the dielectric ceramic 102 is connected to the power supply terminal of the FPC 101, the power supply module 2 can supply power to the dielectric ceramic 102 by using the FPC 101, so as to ensure that a therapeutic current 6 can be generated between the dielectric ceramic 102 in the first arbitrary region 4 and the dielectric ceramic 102 in the second arbitrary region 5, and further ensure that the electric field therapy system can generate therapeutic currents 6 in any direction and any quantity at the target site.

[0065] Since the output terminal of the temperature sensor 10 is connected to the input terminal of the FPC 101, and the output terminal of the FPC 101 is connected to the input terminal of the control module 3, the temperature sensor 10 can send a temperature signal to the control module 3 by using the FPC 101, so as to ensure that the control module 3 can control the on / off of the first switch 7 and the second switch 8 according to the temperature of the electrode 1, avoid damaging the target site due to the too high temperature of the electrode 1, and at the same time ensure that the treatment time of the electric field therapy system for the target site can meet the treatment requirements.

[0066] Since multiple FPCs 101 are connected in sequence to form a substrate, multiple electrodes 1 form an integral structure, thus reducing the wiring of the electric field therapy system, which is not only beneficial to the carrying of the electric field therapy system, but also improves the use comfort of the electric field therapy system. At the same time, by using the flexibility of the FPC 101, the substrate can be bent, so that the electric field therapy system can adapt to target sites of different shapes, making the overall versatility stronger and the use more convenient.

[0067] It should be noted that the FPC 101 is a flexible printed circuit board made of polyimide or polyester film as the base material, with high reliability and excellent flexibility. The specific type of the FPC 101 can be set according to actual needs, and no limitation is made thereto.

[0068] The dielectric ceramic 102 is also called dielectric ceramic. The dielectric ceramic 102 has the polarization ability under the action of an electric field and can establish an electric field in the body for a long time. The specific type of the dielectric ceramic 102 can be set according to actual needs, and no limitation is made thereto. For example, the dielectric ceramic 102 can be in a ring structure, and the temperature sensor 10 is located in the middle of the dielectric ceramic 102.

[0069] In related embodiments, multiple electrodes 1 are separately arranged into multiple groups, each group having multiple electrodes. The structure of each group is rectangular, but in the structure of each group, the heating is most obvious at the edge corners, and this position is more likely to reach the set threshold of 42°C, resulting in a relatively high probability of power-off of the electrode 1 and making it difficult to ensure a long treatment time. However, in the electric field treatment system of the present embodiment, since multiple FPCs 101 are connected in sequence to form a substrate, the multiple electrodes 1 form an integral structure, thereby greatly reducing the probability of power-off of the electrode 1 and ensuring that the treatment time of the electric field treatment system for the target site can meet the treatment requirements.

[0070] As Figure 6 shown, in some embodiments, the electric field treatment system further includes a protective cover 11 and an air guiding member 12. The protective cover 11 is disposed on a side of the substrate away from the dielectric ceramic 102, and a cavity is formed between the protective cover 11 and the substrate. The air guiding member 12 is disposed on the protective cover 11 and is in communication with the cavity. The input end of the air guiding member 12 is connected to the output end of the control module 3.

[0071] It can be understood that since a cavity is formed between the protective cover 11 and the substrate and the air guiding member 12 is in communication with the cavity, the air guiding member 12 can realize the air flow inside and outside the cavity under the control of the control module 3, thereby accelerating the heat dissipation of the FPC 101, which can not only ensure the stable discharge of the electrode 1 but also reduce the problem of the electrode 1 having too high a temperature.

[0072] It should be noted that the protective cover 11 is used to protect the FPC 101, the dielectric ceramic 102, etc., and is used to carry the air guiding member 12 and form a cavity. The specific type of the protective cover 11 can be set according to actual needs and is not limited thereto. By way of example, the protective cover 11 can be a rigid cover structure. When the target site is the human head, the protective cover 11 can be a structure similar to a helmet. Among them, an opening opposite to the air guiding member 12 can also be provided on the protective cover 11 so that the air guiding member 12 cooperates with the opening to enable the stable flow of air between the air inside the cavity and the air outside the cavity.

[0073] The air guiding member 12 is used to form an air flow between the inside and the outside of the cavity. The specific type of the air guiding member 12 can be set according to actual needs and is not limited thereto. By way of example, the air guiding member 12 can be a fan, and the air guiding member 12 can adjust the rotation speed under the control of the control module 3, thereby adjusting the heat dissipation efficiency of the electrode 1.

[0074] As Figure 6 shown, in some embodiments, the electrode 1 further includes a welding ring 103. The welding ring 103 is disposed between the dielectric ceramic 102 and the FPC 101, and one end of the welding ring 103 is connected to the power supply end of the FPC 101, and the end of the welding ring 103 away from the FPC 101 is connected to the power supply end of the dielectric ceramic 102.

[0075] It can be understood that since the welding ring 103 is arranged between the dielectric ceramic 102 and the FPC 101, and one end of the welding ring 103 is connected to the power supply end of the FPC 101, and the end of the welding ring 103 far from the FPC 101 is connected to the power supply end of the dielectric ceramic 102, not only the stable arrangement between the dielectric ceramic 102 and the FPC 101 is realized, but also the FPC 101 can supply power to the dielectric ceramic 102 by using the welding ring 103, so as to ensure that a therapeutic current 6 can be generated between the dielectric ceramic 102 in the first arbitrary region 4 and the dielectric ceramic 102 in the second arbitrary region 5, and further ensure that the electric field treatment system can generate therapeutic currents 6 in any direction and any quantity at the target site.

[0076] It should be noted that the welding ring 103 is used to connect the dielectric ceramic 102 and the FPC 101. The specific type of the welding ring 103 can be set according to actual needs, and there is no limitation in this regard. The welding ring 103 can be a ring-shaped solder joint formed by a welding process. Among them, the welding ring 103 and the dielectric ceramic 102 can be concentrically arranged.

[0077] As Figure 6 shown, in some embodiments, the electrode 1 further includes an insulating glue 104 and / or an invisible glue 105 (Ultraviolet Rays, UV glue). The insulating glue 104 is arranged between the dielectric ceramic 102 and the FPC 101, and one end of the insulating glue 104 is connected to the FPC 101, and the end of the insulating glue 104 far from the FPC 101 is connected to the dielectric ceramic 102. The insulating glue 104 wraps the welding ring 103. The invisible glue 105 is arranged between the temperature sensor 10 and the FPC 101, and one end of the invisible glue 105 is connected to the FPC 101, and the end of the invisible glue 105 far from the FPC 101 is connected to the temperature sensor 10. The invisible glue 105 is located inside the welding ring 103.

[0078] It can be understood that since the insulating glue 104 is arranged between the dielectric ceramic 102 and the FPC 101 and the insulating glue 104 wraps the welding ring 103, not only the arrangement between the dielectric ceramic 102 and the FPC 101 is more stable and firm, ensuring that the dielectric ceramic 102 stably generates the therapeutic current 6 at the target site, but also the welding ring 103 can be insulated and protected to avoid failure problems such as electric leakage and short circuit.

[0079] Since the invisible glue 105 is arranged between the temperature sensor 10 and the FPC 101 and the invisible glue 105 is located inside the welding ring 103, the arrangement between the temperature sensor 10 and the FPC 101 is more stable and firm, ensuring that the temperature sensor 10 can stably detect the temperature of the dielectric ceramic 102.

[0080] It should be noted that the insulating adhesive 104 is a composite adhesive with good electrical insulation performance. The specific type of the insulating adhesive 104 can be set according to actual needs, and no limitation is imposed thereon.

[0081] The light-curing adhesive 105, also known as photosensitive adhesive and ultraviolet light-curing adhesive, is a type of adhesive that must be cured by ultraviolet light irradiation. The specific type of the light-curing adhesive 105 can be set according to actual needs, and no limitation is imposed thereon.

[0082] As Figure 6 shown, in some embodiments, the electrode 1 further includes a conductive gel 106, and the conductive gel 106 is disposed on a side of the dielectric ceramic 102 away from the FPC 101.

[0083] It can be understood that since the conductive gel 106 is disposed on a side of the dielectric ceramic 102 away from the FPC 101, the dielectric ceramic 102 can be attached to the target site by using the conductive gel 106, so as to ensure the stable generation of the treatment current 6 while making the setting of the electrode 1 on the target site more fitting and comfortable, and further making the use of the electric field treatment system more convenient.

[0084] It should be noted that the conductive gel 106 is an adhesive that has certain conductivity after curing or drying. The specific type of the conductive gel 106 can be set according to actual needs, and no limitation is imposed thereon.

[0085] As Figure 6 shown, in some embodiments, the electrode 1 further includes a heat sink 107, and the heat sink 107 is disposed on a side of the FPC 101 away from the dielectric ceramic 102.

[0086] It can be understood that since the heat sink 107 is disposed on a side of the FPC 101 away from the dielectric ceramic 102, the FPC 101 can be in contact with the external air by using the heat sink 107, thereby effectively improving the heat dissipation efficiency of the electrode 1 and reducing the occurrence of the problem of overheating of the electrode 1.

[0087] It should be noted that the heat sink 107 is used for heat dissipation of the electrode 1. The specific type of the heat sink 107 can be set according to actual needs, and no limitation is imposed thereon. For example, the heat sink 107 can be a metal with good heat dissipation such as copper or stainless steel, or a heat dissipation manifold with a flow channel, and an endothermic fluid is conducted in the flow channel.

[0088] As Figure 6 shown, in some embodiments, the electrode 1 further includes a reinforcing plate 108, and the reinforcing plate 108 is disposed on a side of the FPC 101 away from the dielectric ceramic 102.

[0089] It can be understood that since the reinforcing plate 108 is disposed on the side of the FPC 101 away from the dielectric ceramic 102, the FPC 101 can utilize the reinforcing plate 108 to increase the overall structural strength, thereby improving the stability of the electrode 1 and ensuring that the electric field therapy system generates therapeutic currents 6 in any direction and any number at the target site.

[0090] It should be noted that the reinforcing plate 108 is used to increase the thickness of the FPC 101 to improve the structural strength of the electrode 1. The specific type of the reinforcing plate 108 can be set according to actual needs and is not limited thereto. It should be noted that the reinforcing plate 108 itself is also flexible, and after the addition of the reinforcing plate 108, the substrate can still be bent.

[0091] Among the multiple electrodes 1 in the first arbitrary region 4 and among the multiple electrodes 1 in the second arbitrary region 5, synchronous energization or synchronous power-off can be achieved through software to ensure the stable generation of the therapeutic current 6. At the same time, a controllable on-off path can also be provided therebetween to ensure that the multiple electrodes 1 in the first arbitrary region 4 and the multiple electrodes 1 in the second arbitrary region 5 can be synchronously energized or synchronously powered off.

[0092] As Figure 2 shown, in some embodiments, the electric field therapy system further includes a plurality of third switches 13. A third switch 13 is disposed between any two electrodes 1. The input end of the third switch 13 is connected to the output end of the control module 3. The control module 3 is configured to control the on-off of the plurality of third switches 13 to connect the electrodes 1 in the first arbitrary region 4 in series and the electrodes 1 in the second arbitrary region 5 in series.

[0093] It can be understood that since a third switch 13 is disposed between any two electrodes 1, the third switch 13 can conduct or disconnect the path between any two electrodes 1 under the control of the control module 3. Thus, by controlling the on-off of the plurality of third switches 13, the electrodes 1 in the first arbitrary region 4 can be connected in series and the electrodes 1 in the second arbitrary region 5 can be connected in series, thereby realizing the synchronous energization of the electrodes 1 in the first arbitrary region 4 and the synchronous energization of the electrodes 1 in the second arbitrary region 5, and further ensuring the stable generation of the therapeutic current 6 and ensuring a good therapeutic effect of the electric field therapy system on the target site.

[0094] It should be noted that the third switch 13 is used to control the on-off of the path between two electrodes 1. The specific type of the third switch 13 can be set according to actual needs and is not limited thereto. By way of example, the third switch 13 can be an analog switch, such as a MOS transistor.

[0095] As Figure 2 、 Figure 3 and Figure 4As shown, in some embodiments, the electric field therapy system includes a first distribution area 14 and a second distribution area 15. The first distribution area 14 is arranged along a first direction, and a plurality of electrodes 1 arranged in an array are provided in the first distribution area 14. The second distribution area 15 is arranged along a second direction, and a plurality of electrodes 1 arranged in an array are provided in the second distribution area 15. Among them, the first direction and the second direction form a preset angle, and the middle parts of the first distribution area and the second distribution area overlap.

[0096] It can be understood that since the first distribution area 14 is arranged along the first direction, the second distribution area 15 is arranged along the second direction, the first direction and the second direction form a preset angle, and the middle parts of the first distribution area and the second distribution area overlap, the plurality of electrodes 1 of the electric field therapy system are distributed in an "X" shape, so that the electric field therapy system can adapt to the target part of the human head and ensure the stable treatment of tumors in the human head by the electric field therapy system.

[0097] It should be noted that the preset angle can be any angle and is not limited thereto. By way of example, the preset angle can be 90 degrees, that is, the plurality of electrodes 1 of the electric field therapy system are distributed in a "cross" shape.

[0098] Among them, the number and specific arrangement of the electrodes 1 in the first distribution area 14 and the second distribution area 15 can be set according to actual needs and are not limited thereto. By way of example, the plurality of electrodes 1 in the first distribution area 14 can be a 3-by-6 array, the plurality of electrodes 1 in the second distribution area 15 can be a 3-by-9 array, and the overlapping part of the plurality of electrodes 1 in the first distribution area 14 and the plurality of electrodes 1 in the second distribution area 15 is a 3-by-3 array. Thus, the electric field therapy system has thirty-six electrodes 1.
