Description

Technical Field

[0001] The present invention relates to the technical fields of medical equipment, power supply, etc., and in particular to a tumor electric field therapeutic apparatus and a power supply device and a power supply method thereof. Background Art

[0002] At present, the main treatments for tumors include surgery, radiotherapy, chemotherapy, etc., but they 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 Treating Fields (TTF) is a method of applying a low-intensity, medium-frequency alternating electric field to cancer cells, thereby interfering with the mitotic process of cancer cells, inhibiting the mitosis of cancer cells, and inducing apoptosis of cancer cells, thereby achieving a therapeutic effect. Studies have shown that electric field therapy is effective in the treatment of diseases such as glioblastoma, non-small cell lung cancer, and malignant pleural mesothelioma. The electric field applied by this method can affect the aggregation of tubulin in dividing cancer cells, prevent the formation of spindles in dividing cancer cells, inhibit the mitotic process of cancer cells, and induce apoptosis of cancer cells.

[0003] The electric field therapy device for treating tumors mainly includes a main unit of the tumor electric field therapy device and an electrode patch electrically connected to the main unit of the tumor electric field therapy device. The electrode patch is applied to the skin of the human body corresponding to the lesion so that an alternating electric signal is applied to the tissue area where the tumor is located to perform electric field tumor therapy.

[0004] In the related art, when the host of the tumor electric field therapy device needs to be used on the move, it only uses a battery of fixed capacity to power it, and has several spare replacement batteries of the same capacity for replacement. It needs to be charged through a wired power adapter, so its flexibility and convenience are poor. The tumor electric field therapy device is only powered by a battery or a wired power adapter, which results in poor flexibility and convenience during use.

[0044] Embodiments of the present invention 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Figure 3 Schematic diagram of a tumor electric field therapy device 300 provided in accordance with an embodiment of the present application.

[0046] like Figure 3 As shown, the tumor electric field therapy device 300 provided in the embodiment of the present application includes at least an electric field module 310 and a power supply control module 320 .

[0047] Exemplarily, the electric field module 310 is configured to generate an alternating electric signal. The power supply control module 320 is configured to control a target power supply device among the plurality of power supply devices to supply power to the electric field module 310 .

[0048] The multiple power supply devices include at least two. The embodiment of the present application is described by taking three power supply devices as an example, namely, power supply device 331, power supply device 332, and power supply device 333. The power supply device can be arranged in the tumor electric field therapy device 300, or it can be an external device independent of the tumor electric field therapy device 300. For example, power supply devices 331 and 332 are arranged in the tumor electric field therapy device 300, and power supply device 333 is an external device independent of the tumor electric field therapy device 300.

[0049] The power supply control module 320 has functions such as signal detection, control switching of power supply devices, and signal processing. For example, the power supply control module 320 may include a controller. When the power supply control module 320 determines that multiple power supply devices can be used to supply power to the electric field module 310, the target power supply device is determined from the multiple power supply devices based on the power supply priority information preset in the power supply control module 320, and then the target power supply device is controlled to supply power to the electric field module 310 based on the power supply mode corresponding to the target power supply device, so as to drive the electric field module 310 to generate an alternating electric signal.

[0050] For example, the power supply device 331 is a wireless power supply device, the power supply device 332 is a battery device, and the wireless power supply device and the battery device are arranged in the tumor electric field therapy device 300. The power supply device 333 is an external power supply device, and the external power supply device is an external device independent of the tumor electric field therapy device 300.

[0051] Exemplarily, the power supply priority information is used to indicate that the priority of the external power supply device is higher than the priority of the wireless power supply device, and the priority of the wireless power supply device is higher than the priority of the battery device.

[0052] Exemplarily, when the target power supply device is a wireless power supply device, the power supply control module 320 is also used to determine the power supply mode corresponding to the target power supply device. The power supply control module 320 is specifically used to: determine whether the wireless power supply device directly or indirectly supplies power to the electric field module 310 based on the power supply and demand relationship associated with the wireless power supply device and the electric field module 310. The power supply and demand relationship is specifically the relationship between the first power supply power provided by the wireless power supply device and the second power supply power required by the electric field module 310.

[0053] For example, the power supply control module 320 is configured to control the wireless power supply device to directly power the electric field module 310 when the first power supply power is greater than the second power supply power, and control the wireless power supply device to charge the battery device;

[0054] When the first power supply power is less than or equal to the second power supply power, the power supply control module 320 is configured to control the wireless power supply device to indirectly power the electric field module 320; that is, the power supply control module 320 controls the wireless power supply device to charge the battery device, and controls the battery device to power the electric field module 310.

[0055] Figure 4 A schematic diagram of a tumor electric field therapy device 40 provided in accordance with another embodiment of the present application.

[0056] like Figure 4 As shown, the tumor electric field therapy device 40 includes a therapy device host 400 and a wireless power supply device. The wireless power supply device includes an electromagnetic power supply device 500, and the electromagnetic power supply device 500 can be a wireless charging stand. The connection between each device or each module referred to in the embodiment of the present application includes an electrical connection.

[0057] The therapeutic apparatus host 400 includes an electric field module 410 that generates an alternating current signal, a power switching module 420 that is communicatively connected to the electric field module 410, a battery device 430 and a first power input module 440 that are both connected to the power switching module 420, a charging management module 450 that is connected to the battery device 430, a power conversion module 460 that simultaneously connects the charging management module 450 and the power switching module 420, and a receiving coil module 470 that is connected to the power conversion module 460. The battery device 430 can be replaced when the power is exhausted so as to power the therapeutic apparatus host 400 for a long time.

[0058] The electromagnetic power supply device 500 includes a second power input module 510 , a transmission driving module 520 connected to the second power input module 510 , and a transmission coil module 530 connected to the transmission driving module 520 and capable of transmitting a signal to the receiving coil module 470 .

[0059] The first power input module 440 is connected to the electric field module 410 through the power switching module 420. The first power input module 440 is used to receive an electrical signal from an external power supply device (not shown) to directly power the electric field module 410. For example, the external power supply device (not shown) includes an external AC power supply and a power adapter (not shown), and the first power input module 440 includes a power adapter input module (not shown) connected to the power adapter (not shown). The external power supply device (not shown) directly powers the electric field module 410 through the first power input module 440.

[0060] The electromagnetic power supply device 500 is used to convert an external AC power signal into an electromagnetic wave signal. The receiving coil module 470 is wirelessly connected to the electromagnetic power supply device 500, and the power conversion module 460 is connected to the receiving coil module 470. The receiving coil module 470 converts the received electromagnetic wave signal into an AC power signal and transmits the AC power signal to the power conversion module 460, and the power conversion module 460 converts the AC power signal into a DC power signal to directly or indirectly power the electric field module 410.

[0061] The power switching module 420 is directly or indirectly connected to multiple power supply devices (external power supply device, electromagnetic power supply device 500, battery device 430). Specifically, the power switching module 420 is electrically connected to the power conversion module 460, the battery device 430 and the first power input module 440. The power switching module 420 switches multiple power supply devices so that the target power supply device supplies power to the electric field module 410 based on the power supply mode corresponding to the target power supply device.

[0062] Specifically, the power supply control module includes a controller (not shown), a power switching module 420 and at least one power metering chip (not shown), wherein the controller (not shown) may be a device independent of the power switching module 420, or may be arranged in the power switching module 420. If the controller (not shown) is independent of the power switching module 420, the controller (not shown) may be used to monitor signals and control the power switching module 420 to switch the corresponding power supply device for power supply. If the controller (not shown) is arranged in the power switching module 420, the power switching module 420 may be used to monitor signals and switch the corresponding power supply device for power supply. The electric field module 410 needs to change its output voltage, current and other parameters in real time according to the user's body surface temperature, so the power supply power required by the electric field module 410 at different times is not constant, but changes all the time. A power metering chip (not shown) is arranged in the electric field module 410 for real-time monitoring of changes in the power supply power required by the electric field module 410. A power metering chip (not shown) is also arranged in the power switching module 420 for real-time monitoring of the power supply power transmitted by the electromagnetic power supply device 500.

[0063] The power switching module 420 or the controller (not shown) is used to monitor in real time whether the first power input module 440 is inserted into the power adapter (not shown). If the first power input module 440 is inserted into the power adapter and connected to the mains, the external power supply device is switched to supply power; if the power adapter (not shown) is not inserted, the power switching module 420 or the controller (not shown) is used to monitor in real time and determine whether wireless power supply is currently being performed. If wireless power supply is not being performed, the battery device 430 is switched to supply power. If the detection therapeutic instrument host 400 is performing wireless power supply, it is determined whether the wireless power supply power is greater than the power supply power required by the electric field module 410. If the wireless power supply power is greater than the power supply power required by the electric field module 410, the electromagnetic power supply device 500 is controlled to directly supply power to the electric field module 410 and charge the battery device 430 at the same time. If the wireless power supply power is less than or equal to the power supply power required by the electric field module 410, the battery device 430 is charged by the electromagnetic power supply device 500, and the electric field module 410 is powered by the battery device 430. If the electric field module 410 stops working and the therapeutic device host 400 is turned off, the power supply is terminated. If the electric field module 410 stops working and the therapeutic device host 400 is not turned off, a cycle of comparing the wireless power supply power and the power supply power of the electric field module 410 is entered.

[0064] The charging management module 450 is connected to the electromagnetic power supply device 500 and the battery device 430, and a voltage threshold is set therein. When the battery device 430 is charged by the electromagnetic power supply device 500, the charging management module 450 is used to execute:

[0065] When the voltage value of the battery device 430 is lower than the first voltage value, the battery device 430 is charged by the trickle charging mode. In this example, the first voltage value is 8.4V. When the voltage of the battery device 430 is lower than 8.4V, if the battery device 430 continues to be used, the voltage of the battery device 430 will drop rapidly, and may be damaged due to over-discharge, affecting the battery life. Therefore, when the voltage of the battery device 430 is lower than 8.4V, it is necessary to enter the trickle charging mode for small current charging to achieve pre-charging of the fully discharged battery device 430, that is, recovery charging. The trickle charging current can be set to 15% of the constant current charging current. For example, when the constant current charging current is 1A, the trickle charging current is 150mA. The battery device 430 includes a lithium-ion battery. Since the lithium-ion battery has a higher energy ratio, if the fast charging mode is directly entered, it will damage the battery, affect the battery life and may bring safety hazards. Therefore, it is necessary to enter the trickle charging mode for small current charging;

[0066] When the voltage value of the battery device 430 is greater than or equal to the first voltage value, and the difference between the voltage value and the second voltage value is greater than the preset voltage threshold, the battery device 430 is charged through the constant current charging mode. In this example, the second voltage value is 12.6V. The difference greater than the preset voltage threshold indicates that the voltage of the battery device 430 is not close to the constant voltage charging voltage. The second voltage value is the full-charge voltage of the battery device 430, and the first voltage value is less than the second voltage value. When the voltage of the battery device 430 is greater than or equal to 8.4V, the condition for fast charging of the battery is met, so it can enter the constant current charging mode with a fast charging speed, which will shorten the charging time and improve the charging efficiency;

[0067] When the difference between the voltage value of the battery device 430 and the second voltage value is less than or equal to the preset voltage threshold, it means that the voltage value of the battery device 430 continues to rise and approaches the constant voltage charging voltage, and the battery device 430 is charged in the constant voltage charging mode. In practical applications, the preset voltage threshold can be set according to the specific situation, for example, it can be set to 0V, 0.1V, 0.11V, 0.2V or 1V, etc.

[0068] Exemplarily, the second power input module 510 in the electromagnetic power supply device 500 is used to convert an external AC signal into a DC signal to obtain the required specific voltage and current. In this example, the external AC signal is a mains AC signal. The transmitting drive module 520 is connected to the second power input module 510, and the transmitting drive module 520 is used to resonate the input specific DC signal to obtain a high-frequency AC signal and transmit it to the transmitting coil module 530. The transmitting coil module 530 is connected to the transmitting drive module 520, and the transmitting coil module 530 is used to convert the high-frequency AC signal to obtain an electromagnetic wave signal and transmit it.

[0069] An example of a power supply process: The second power input module 510 in the electromagnetic power supply device 500 converts the input AC power into DC power, and the DC power is converted into high-frequency AC power through the resonance conversion of the transmitting drive module 520. The high-frequency AC current is converted into electromagnetic waves through the transmitting coil module 530, and the transmitting coil module 530 radiates electromagnetic waves into the air. According to the principle of electromagnetic induction, the receiving coil module 470 in the changing magnetic field at this time generates a corresponding induced electromotive force, thereby realizing the wireless transmission of electric energy. The receiving coil module 470 converts the electromagnetic waves into AC power, and the AC power is converted into DC power by the power conversion module 460. The charging management module 450 directly charges the battery device 430 based on the DC power, and the DC power can also be directly used to power the electric field module 410. The power switching module 420 is mainly used to switch the power supply device that powers the electric field module 410.

[0070] It can be seen that the tumor electric field therapy device 40 of the embodiment of the present application still has the function of battery power supply. On this basis, a wireless charging receiving module, such as a receiving coil module 470, is added to the host 400 of the therapy device, and an electromagnetic power supply device 500, such as a wireless charging stand, is added to the tumor electric field therapy device 40. The wireless power supply method powered by the electromagnetic power supply device 500 is based on the Faraday electromagnetic induction principle and belongs to "electromagnetic coupling wireless power supply". The operating frequency of this wireless power supply method is generally between 100kHz and 300kHz. The electromagnetic power supply device 500 has the ability to convert electrical energy into magnetic energy. The wireless charging receiving module inside the host 400 of the therapy device can convert the magnetic energy received by the receiving coil module 470 into electrical energy to charge the battery device 430 inside the host 400 of the therapy device, or directly power the electric field module 410 to directly drive the host 400 of the therapy device to work, and the power of the battery device 430 is not consumed at this time. The wireless power supply method of the embodiment of the present application does not need to transmit electric energy to the device through cables like a traditional charger or adapter. It only needs the therapeutic device host 400 and the electromagnetic power supply device 500 to be in contact or close to each other to achieve electrical connection, so as to transmit and supply electric energy, and achieve the effect of "take it and go, put it and charge it". It is suitable for users' activities at home and scenarios of replenishing electric energy. The power supply method is more flexible, which greatly improves the convenience of using the tumor electric field therapy device.

The wireless power supply device includes a microwave power supply device 700, and the microwave power supply device 700 can be a charging base station. The connection between each device or each module referred to in the embodiment of the present application includes an electrical connection.

[0073] The therapeutic apparatus host 600 includes an electric field module 610 for generating an alternating current signal, a power switching module 620 connected to the electric field module 610, a battery device 630 connected to the power switching module 620, a first power input module 640, a microwave rectifier module 660, a charging management module 650 connected to both the battery device 630 and the microwave rectifier module 660, and a receiving antenna module 670 connected to the microwave rectifier module 660. The battery device 630 can be replaced when the battery is exhausted so as to provide power to the therapeutic apparatus host 600 for a long time.

[0074] The microwave power supply device 700 includes a third power input module 710, a microwave signal source module 740 connected to the third power input module 710, a microwave power amplification module 720 connecting the third power input module 710 and the microwave signal source module 740, and a transmitting antenna module 730 connected to the microwave power amplification module 720.

[0075] The first power input module 640 is connected to the electric field module 610 through the power switching module 620. The first power input module 640 is used to receive an electrical signal from an external power supply device (not shown) to directly power the electric field module 610. For example, the external power supply device includes an external AC power supply and a power adapter (not shown), and the first power input module 640 includes a power adapter input module (not shown) connected to the power adapter (not shown). The external power supply device (not shown) directly powers the electric field module 610 through the first power input module 640.

[0076] Exemplarily, the microwave power supply device 700 is used to convert an external AC power signal into a microwave signal. The receiving antenna module 670 is wirelessly connected to the microwave power supply device 700, and the microwave rectifier module 660 is connected to the receiving antenna module 670. For example, the receiving antenna module 670 receives the microwave signal, and the microwave rectifier module 660 converts the microwave signal into a DC signal, and the DC signal is used to directly or indirectly power the electric field module 610.

[0077] Exemplarily, the power switching module 620 is directly or indirectly connected to multiple power supply modules (external power supply device, microwave power supply device 700, battery device 630). Specifically, the power switching module 620 is electrically connected to the microwave rectifier module 660, the battery device 630 and the first power input module 640 respectively. The power switching module 620 switches multiple power supply devices so that the target power supply device supplies power to the electric field module 610 based on the power supply mode corresponding to the target power supply device.

[0078] Specifically, the power supply control module includes a controller (not shown), a power switching module 620 and at least one power metering chip (not shown), wherein the controller may be a device independent of the power switching module 620, or may be arranged in the power switching module 620. If the controller (not shown) is independent of the power switching module 620, the controller (not shown) may be used to monitor signals and control the power switching module 620 to switch the corresponding power supply device for power supply. If the controller (not shown) is arranged in the power switching module 620, the power switching module 620 may be used to monitor signals and switch the corresponding power supply device for power supply. The electric field module 610 needs to change its output parameters such as voltage and current in real time according to the user's body surface temperature, so the power supply power required by the electric field module 610 at different times is not constant, but changes all the time. A power metering chip (not shown) is arranged in the electric field module 610 for real-time monitoring of changes in the power supply power required by the electric field module 610. A power metering chip (not shown) is also arranged in the power switching module 620 for real-time monitoring of the power supply power transmitted by the microwave power supply device 700.

[0079] The power switching module 620 or the controller (not shown) is used to monitor in real time whether the first power input module 640 is inserted into the power adapter (not shown). If the first power input module 640 is inserted into the power adapter (not shown) and connected to the mains, the external power supply device is switched to supply power; if the power adapter (not shown) is not inserted, the power switching module 620 or the controller (not shown) is used to monitor in real time and determine whether wireless power supply is currently being performed. If wireless power supply is not being performed, the battery device 630 is switched to supply power. If the detection therapeutic instrument host 600 is performing wireless power supply, it is determined whether the wireless power supply power is greater than the power supply power required by the electric field module 610. If the wireless power supply power is greater than the power supply power required by the electric field module 610, the microwave power supply device 700 is controlled to directly supply power to the electric field module 610 and charge the battery device 630 at the same time. If the wireless power supply power is less than or equal to the power supply power required by the electric field module 610, the battery device 630 is charged by the microwave power supply device 700, and the electric field module 610 is powered by the battery device 630. If the conditions that the electric field module 610 stops working and the therapeutic device host 600 is turned off are met, the power supply is terminated; if the conditions that the electric field module 610 stops working and the therapeutic device host 600 is turned off are not met, a cycle of comparing the wireless power supply power and the power supply power of the electric field module 610 is entered.

[0080] The charging management module 650 is connected to the microwave power supply device 700 and the battery device 630, and has a preset voltage threshold. When the battery device 630 is charged by the microwave power supply device 700, the charging management module 650 is used to execute:

[0081] When the voltage value of the battery device 630 is lower than the first voltage value, the battery device 630 is charged by the trickle charging mode. In this example, the first voltage value is 8.4V. When the voltage of the battery device 630 is lower than 8.4V, if the battery device 630 continues to be used, the voltage of the battery device 630 will drop rapidly, and may be damaged due to over-discharge, affecting the battery life. Therefore, when the voltage of the battery device 630 is lower than 8.4V, it is necessary to enter the trickle charging mode for small current charging to achieve pre-charging of the fully discharged battery device 630, that is, recovery charging. The trickle charging current can be set to 15% of the constant current charging current. For example, when the constant current charging current is 1A, the trickle charging current is 150mA. The battery device 630 includes a lithium-ion battery. Since the lithium-ion battery has a higher energy ratio, if the fast charging mode is directly entered, it will damage the battery, affect the battery life and may bring safety hazards. Therefore, it is necessary to enter the trickle charging mode for small current charging;

[0082] When the voltage value of the battery device 630 is greater than or equal to the first voltage value and the difference between the voltage value of the battery device 630 and the second voltage value is greater than a preset voltage threshold, the battery device 630 is charged in a constant current charging mode. In this example, the second voltage value is 12.6V. The difference being greater than the preset voltage threshold indicates that the voltage of the battery device 630 is not yet close to the constant voltage charging voltage. Among them, the second voltage value is the full-charge voltage of the battery device 630, and the first voltage value is less than the second voltage value. When the voltage value of the battery device 630 is greater than or equal to 8.4V, the condition for fast charging of the battery is met, so the constant current charging mode with a fast charging speed can be entered, which shortens the charging time and improves the charging efficiency;

[0083] When the difference between the voltage value of the battery device 630 and the second voltage value is less than or equal to the preset voltage threshold, it means that the voltage value of the battery device 630 continues to rise and approaches the constant voltage charging voltage, and the battery device 630 is charged in the constant voltage charging mode. In practical applications, the preset voltage threshold is less than 1% of the full-charge voltage value of the battery device 630, and can be set according to specific circumstances, for example, it can be set to 0V, 0.1V, 0.11V, 0.2V or 1V, etc.

[0084] Exemplarily, the third power input module 710 in the microwave power supply device 700 is used to convert an external AC signal (such as a mains AC signal) into a DC signal to obtain the required specific voltage and current. The third power input module 710 is connected to the microwave signal source module 740 and the microwave power amplifier module 720 to power both. The microwave signal source module 740 is connected to the third power input module 710, and the microwave signal source module 740 is used to generate a low-power (low power, such as milliwatt) microwave signal based on the DC signal. The microwave power amplifier module 720 is connected to the microwave signal source module 740, and the microwave power amplifier module 720 is used to amplify the low-power microwave signal to generate a high-power (high power, such as watt) microwave signal. The transmitting antenna module 730 is connected to the microwave power amplifier module 720, and the transmitting antenna module 730 is used to transmit the high-power microwave signal into space.

[0085] An example of a power supply process: The embodiment of the present application adopts microwave wireless energy transmission technology to transmit energy from the microwave power supply device 700 to the therapeutic instrument host 600 in the form of electromagnetic waves. The third power input module 710 in the microwave power supply device 700 converts the input alternating current into direct current to power the microwave signal source module 740 and the microwave power amplifier module 720. The microwave signal source module 740 generates a low-power (milliwatt) microwave signal, and amplifies the low-power microwave signal through the microwave power amplifier module 720, and finally outputs a high-power (watt) microwave signal. In general, the function of the microwave signal source module 740 and the microwave power amplifier module 720 is to convert direct current energy into microwave energy. The transmitting antenna module 730 radiates the high-power microwave signal from the microwave power amplifier module 720 into space. The receiving antenna module 670 in the therapeutic apparatus host 600 can receive microwave signals of the corresponding frequency band in the area, and send the microwave signals to the microwave rectifier module 660, which converts the received microwave signals into direct current signals to power the therapeutic apparatus host 600. The charging management module 650 directly charges the battery device 630 based on the direct current, and the direct current can also be directly used to power the electric field module 610. The power switching module 620 is mainly used to switch the power supply device that powers the electric field module 610.

[0086] In this embodiment, when the distance between the therapeutic instrument host 600 and the microwave power supply device 700 is large, the therapeutic instrument host 600 can also receive the signal transmitted by the microwave power supply device 700, thereby achieving the effect of "powering and charging in the air". "Powering and charging in the air" relies on microwave wireless energy transmission technology, and the frequency of microwaves is between 300MHz-300GHz. The power supply and charging system in the air includes a microwave power supply device 700 (such as a "charging base station" or "charging pile"), through which the microwave power supply device 700 transmits electromagnetic energy through a highly directional transmitting antenna. When the therapeutic instrument host 600 with a receiving antenna module 670 enters the working area of ​​the transmitting antenna module 730, the electric field energy can be collected and converted into usable electric energy through processing, which can be used to charge the battery device 630, or to drive the electric field module 610 to work and charge the battery device 630 at the same time. The wireless charging transmission method has a long transmission distance, which can normally reach the meter level or even farther. The wireless charging method uses microwave transmission to replace the original power cord for energy transfer, and its advantages are also obvious, and the power supply and charging process is more flexible. Users can wear the therapeutic device host 600 and move around freely in a certain area of ​​their home without having to worry about the power supply of the device, which greatly improves the convenience of the tumor electric field therapy device.

[0087] Figure 1 A schematic flow chart of a power supply method 100 suitable for a tumor electric field therapy device provided in an embodiment of the present application.

[0088] like Figure 1 As shown, the power supply method 100 provided in the embodiment of the present application is suitable for powering the electric field modules 310, 410, 610 of the aforementioned tumor electric field therapy devices 300, 40, 60, and the power supply method 100 at least includes steps S110 to S120.

[0089] Step S110, when multiple power supply devices 331, 332, 333 can be used to power the electric field modules 310, 410, 610, a target power supply device is determined from the multiple power supply devices 331, 332, 333 based on the power supply priority information preset in the tumor electric field therapy device 300, 40, 60.

[0090] Step S120 , controlling the target power supply device to supply power to the electric field modules 310 , 410 , 610 based on the power supply mode corresponding to the target power supply device, so as to drive the electric field modules 310 , 410 , 610 to generate alternating electric signals.

[0091] Exemplarily, the electric field modules 310, 410, 610 of the tumor electric field therapeutic apparatus 300, 40, 60 of the embodiments of the present application can be used to provide alternating electric signals. In order to drive the electric field modules 310, 410, 610 to generate alternating electric signals, it is necessary to power the electric field modules 310, 410, 610 through power supply devices 331, 332, 333. The power supply priorities of the multiple power supply devices 331, 332, 333 that can be used for power supply are different. When it is detected that only one power supply device can be used to power the electric field modules 310, 410, 610, the power supply device is used for power supply. When it is detected that there are multiple power supply devices that can be used to power the electric field modules 310, 410, 610, a target power supply device with a high priority can be determined from the multiple power supply devices based on the preset power supply priority information, and the electric field modules 310, 410, 610 are powered by the target power supply device.

[0092] The power supply mode corresponding to each of the multiple power supply devices 331, 332, and 333 may be different. After determining the target power supply device, the power supply mode corresponding to the target power supply device can be further determined, and then the target power supply device can be controlled to power the electric field modules 310, 410, and 610 based on the corresponding power supply mode.

[0093] It can be understood that the embodiments of the present application configure the tumor electric field therapy apparatus 300, 40, 60 with multiple power supply devices 331, 332, 333 that can be used to power the electric field modules 310, 410, 610, and configure different power supply priorities for each power supply device. When the electric field modules 310, 410, 610 are powered, a power supply device suitable for the current scene can be selected based on the power supply priority to provide power, thereby improving the flexibility of power supply, thereby improving the flexibility and convenience of use of the tumor electric field therapy apparatus 300, 40, 60.

[0094] In another example of the present application, the plurality of power supply devices 331 , 332 , 333 may include at least two of an external power supply device, a wireless power supply device, and a battery device 430 , 630 .

[0095] Exemplarily, the power supply priority information is used to indicate that the priority of the external power supply device is higher than the priority of the wireless power supply device, and the priority of the wireless power supply device is higher than the priority of the battery devices 430 and 630 .

[0096] When it is detected that multiple power supply devices available for powering the electric field modules 310, 410, 610 include external power supply devices and wireless power supply devices, it is determined based on preset power supply priority information that the electric field modules 310, 410, 610 are powered by the external power supply device.

[0097] When it is detected that multiple power supply devices available for powering the electric field modules 310, 410, 610 include an external power supply device and a battery device 430, 630, it is determined based on preset power supply priority information that the electric field modules 310, 410, 610 are powered by the external power supply device.

[0098] When it is detected that multiple power supply devices that can be used to power the electric field modules 310, 410, 610 include wireless power supply devices and battery devices 430, 630, it is determined based on preset power supply priority information that the electric field modules 310, 410, 610 are powered by the wireless power supply devices.

[0099] When it is detected that multiple power supply devices that can be used to power the electric field modules 310, 410, 610 include an external power supply device, a wireless power supply device, and a battery device 430, 630, it is determined based on preset power supply priority information that the electric field modules 310, 410, 610 are powered by the external power supply device.

[0100] If it is detected that only one of the external power supply device, the wireless power supply device, and the battery device 430 , 630 is available for power supply, the electric field module 310 , 410 , 610 is powered by the device.

[0101] Figure 2 A schematic flow chart of a power supply method 200 provided in accordance with another embodiment of the present application.

[0102] like Figure 2 As shown, the power supply method 200 provided in the embodiment of the present application is suitable for powering the electric field modules 310, 410, 610 of the tumor electric field therapy devices 300, 40, 60, and the power supply method 200 at least includes steps S201 to S210.

[0103] Step S201, determine whether the external power supply device is available for power supply. If yes, execute step S202; if not, execute step S203.

[0104] Step S202 , controlling the external power supply device to directly supply power to the electric field modules 310 , 410 , 610 .

[0105] Exemplarily, since the power supply priority of the external power supply device is the first priority (the highest priority), it is possible to first detect whether the external power supply device can be used to power the electric field modules 310, 410, 610. If it is detected that the external power supply device can be used to power the electric field modules 310, 410, 610, a power supply mode corresponding to the external power supply device is further determined, and the power supply mode includes the external power supply device directly powering the electric field modules 310, 410, 610.

[0106] In one example, the external power supply device includes an external AC power supply and a power adapter for converting the external AC power into DC power. When it is detected that the tumor electric field therapy device 300, 40, 60 is electrically connected to the power adapter, it is determined that the external power supply device can be used for power supply, and at this time, the external power supply device is controlled to directly power the electric field modules 310, 410, 610.

[0107] Step S203, determining whether the wireless power supply device can be used for power supply. If not, executing step S204; if yes, executing step S206.

[0108] Step S204 , controlling the battery devices 430 , 630 to directly supply power to the electric field modules 310 , 410 , 610 .

[0109] Exemplarily, the power supply priority of the wireless power supply device is the second priority, and the power supply priority of the battery device 430, 630 is the third priority, the second priority is lower than the first priority, and the third priority is lower than the second priority. In the case where the external power supply device of the first priority cannot be used to power the electric field module 310, 410, 610, it can be further detected whether the wireless power supply device of the second priority can be used to power the electric field module 310, 410, 610.

[0110] If the wireless power supply device is not available for powering the electric field module 310, 410, 610, the electric field module 310, 410, 610 needs to be powered by the battery device 430, 630 based on the third priority, and the battery device 430, 630 includes a battery module arranged in the tumor electric field therapeutic device 300, 40, 60. The battery device 430, 630 is used to power the electric field module 310, 410, 610 when no other power supply device is available for powering. When it is determined that the electric field module 310, 410, 610 is powered by the battery device 430, 630, a power supply mode corresponding to the battery device 430, 630 can be further determined, and the power supply mode includes that the battery device 430, 630 directly powers the electric field module 310, 410, 610, and controls the battery module to power the electric field module 310, 410, 610 based on the corresponding power supply mode.

[0111] Step S205, determining whether the electric field modules 310, 410, 610 have stopped working and whether the tumor electric field therapeutic apparatus host 400, 600 has been turned off. If yes, then the power supply is terminated; if not, then the process returns to step S201.

[0112] After step S202 and step S204, it is possible to detect in real time whether the electric field module 310, 410, 610 stops working and whether the tumor electric field therapy apparatus host 400, 600 is turned off. If it is determined that the electric field module 310, 410, 610 stops working and the tumor electric field therapy apparatus host 400, 600 is turned off, the power supply is terminated.

[0113] Step S206, determining whether the first power supply is greater than the second power supply. If yes, executing step S207; if no, executing step S208.

[0114] In the case where it is determined that the wireless power supply device of the second priority can be used to power the electric field modules 310, 410, 610, the electric field modules 310, 410, 610 can be powered directly or indirectly based on the wireless power supply device. For example, a power supply mode corresponding to the wireless power supply device can be further determined, and the wireless power supply device can be controlled to power the electric field modules 310, 410, 610 based on the corresponding power supply mode. Determining the power supply mode corresponding to the wireless power supply device includes: based on the power supply and demand relationship associated with the wireless power supply device and the electric field modules 310, 410, 610, determining that the electric field modules 310, 410, 610 are powered directly or indirectly by the wireless power supply device. In other words, the power supply mode corresponding to the wireless power supply device includes a direct power supply mode or an indirect power supply mode. The power supply and demand relationship includes the relationship between the first power supply provided by the wireless power supply device and the second power supply required by the electric field modules 310, 410, 610.

[0115] In step S207 , the wireless power supply device is controlled to directly supply power to the electric field modules 310 , 410 , 610 , and charge the battery devices 430 , 630 at the same time.

[0116] Exemplarily, the direct power supply mode includes directly powering the electric field modules 310, 410, and 610 through the wireless power supply device. Specifically, when the first power supply power is greater than the second power supply power, the first power supply power provided by the wireless power supply device is sufficient to power the electric field modules 310, 410, and 610. At this time, the power supply mode corresponding to the wireless power supply device includes controlling the wireless power supply device to directly power the electric field modules 310, 410, and 610. In addition, the first power supply power provided by the wireless power supply device has a remaining power supply in addition to powering the electric field modules 310, 410, and 610, so the wireless power supply device can be controlled to charge the battery devices 430 and 630 based on the remaining power supply power at the same time.

[0117] Step S208 , controlling the wireless power supply device to charge the battery devices 430 , 630 , and controlling the battery devices 430 , 630 to supply power to the electric field modules 310 , 410 , 610 .

[0118] Exemplarily, the indirect power supply mode includes indirectly powering the electric field modules 310, 410, 610 through a wireless power supply device. Specifically, when the first power supply power is less than or equal to the second power supply power, the first power supply power provided by the wireless power supply device is insufficient to directly power the electric field modules 310, 410, 610. At this time, it is necessary to control the wireless power supply device to indirectly power the electric field modules 310, 410, 610. For example, the wireless power supply device is controlled to charge the battery devices 430, 630, and the battery devices 430, 630 are controlled to power the electric field modules 310, 410, 610. It can be seen that when the first power supply power provided by the wireless power supply device is insufficient to directly power the electric field modules 310, 410, 610, the wireless power supply device can indirectly power the electric field modules 310, 410, 610 through the battery devices 430, 630.

[0119] Step S209, determining whether the electric field modules 310, 410, 610 have stopped working and whether the tumor electric field therapeutic apparatus host 400, 600 has been turned off. If yes, then the power supply is terminated; if not, then executing step S210.

[0120] After step S207 and step S208, it is possible to detect in real time whether the electric field modules 310, 410, 610 have stopped working and whether the tumor electric field therapy apparatus host 400, 600 is turned off. If it is determined that the electric field modules 310, 410, 610 have stopped working and the tumor electric field therapy apparatus host 400, 600 is turned off, the power supply is terminated. Among them, step S209 is the same as or similar to step S205.

[0121] Step S210: compare the first power supply power and the second power supply power to determine whether the first power supply power is greater than the second power supply power.

[0122] Depend on Figure 2 As can be seen from the example shown, when it is detected that the external power supply device can be used for power supply, the electric field modules 310, 410, 610 are powered by the external power supply device. If it is detected that the external power supply device is not available for power supply but the wireless power supply device is available for power supply, the electric field modules 310, 410, 610 are powered directly or indirectly by the wireless power supply device. If it is detected that both the external power supply device and the wireless power supply device are not available for power supply, the electric field modules 310, 410, 610 are powered by the battery devices 430, 630. It can be seen that when the electric field modules 310, 410, 610 are powered, the power supply priority of the external power supply device is higher than the power supply priority of the wireless power supply device, and the power supply priority of the wireless power supply device is higher than the power supply priority of the battery devices 430, 630.

[0123] It can be understood that the embodiments of the present application are configured with external power supply devices, radio power supply devices and battery devices 430, 630 with different power supply priorities for the tumor electric field therapy devices 300, 40, 60. In different usage scenarios, the power supply devices 331, 332, 333 that are more convenient or efficient are switched based on the power supply priority to power the electric field modules 310, 410, 610, thereby improving the flexibility of power supply and thus improving the flexibility and convenience of use of the tumor electric field therapy devices 300, 40, 60. The tumor electric field therapy devices 300, 40, 60 are not limited to a certain power supply method and can be applied to more usage scenarios.

[0124] In another example, the wireless power supply device includes multiple types of devices, and the signal processing functions or signal processing processes of different types of wireless power supply devices are different. When controlling the wireless power supply device to power the electric field modules 310, 410, and 610, it is necessary to process the electrical signal based on different signal processing methods according to the type of the wireless power supply device.

[0125] For example, some types of wireless power supply devices can be used to convert external AC power signals into electromagnetic wave signals. For this type of wireless power supply device, the tumor electric field therapy device 300, 40, 60 can convert the electromagnetic wave signal from the wireless power supply device into a DC signal, and directly or indirectly power the electric field module 310, 410, 610 based on the DC signal.

[0126] For example, other types of wireless power supply devices can be used to convert external AC power signals into microwave signals. For this type of wireless power supply device, the tumor electric field therapy device 300, 40, 60 can convert the microwave signal from the wireless power supply device into a DC signal, and directly or indirectly power the electric field module 310, 410, 610 based on the DC signal.

[0127] In actual use scenarios, the tumor electric field therapy apparatus 300, 40, 60 includes a therapy apparatus host 400, 600 and a wireless power supply device. The electric field module 310, 410, 610 and the battery device 430, 630 can be arranged in the therapy apparatus host 400, 600. The user can wear the therapy apparatus host 400, 600 on the body, and stick the electrode patch of the tumor electric field therapy apparatus 300, 40, 60 on a certain part of the body, and the alternating signal generated by the electric field module 310, 410, 610 acts on the corresponding body part through the electrode patch.

[0128] When the user is wearing the therapeutic device, if the user does not need to move long distances, the external power supply device can be inserted into the therapeutic device host through a wired power adapter to power the electric field modules 310, 410, and 610.

[0129] When the user is wearing the therapeutic apparatus host 400, 600, if the user needs to move a long distance, the electric field module 310, 410, 610 can be powered by the wireless power supply device or the battery device 430, 630. For example, when it is detected that the therapeutic apparatus host 400, 600 is in a wireless connection state with the wireless power supply device, it means that the wireless power supply device is in a power supply state, and the electric field module 310, 410, 610 can be powered directly or indirectly by the wireless power supply device. If it is detected that the therapeutic apparatus host 400, 600 is disconnected from the wireless power supply device, the electric field module 310, 410, 610 is powered by the battery device 430, 630.

[0130] Normally, the wireless connection between the therapeutic instrument host 400, 600 and the wireless power supply device requires a certain distance between the two, and different types of wireless power supply devices have different distance requirements. If the distance between the therapeutic instrument host 400, 600 and the wireless power supply device exceeds a certain distance threshold, the therapeutic instrument host 400, 600 and the wireless power supply device will be disconnected. Therefore, when the user wears the therapeutic instrument host 400, 600 and needs to move a long distance, if the therapeutic instrument host 400, 600 and the wireless power supply device are in a wireless connection state, the electric field module 310, 410, 610 can be powered directly or indirectly through the wireless power supply device. If the user walks and causes the distance between the therapeutic instrument host 400, 600 and the wireless power supply device to be far, resulting in the disconnection between the therapeutic instrument host 400, 600 and the wireless power supply device, the battery device 430, 630 can be switched to power the electric field module 310, 410, 610. When it is detected again that the therapeutic instrument host 400, 600 and the wireless power supply device are in a wireless connection state, the wireless power supply device is switched to supply power to the electric field modules 310, 410, 610.

[0131] It can be understood that by configuring power supply devices 331, 332, 333 with different power supply priorities for the tumor electric field therapy devices 300, 40, 60, and switching the power supply device suitable for the current scene based on the power supply priority to power the electric field modules 310, 410, 610, this power supply method is suitable for the power supply requirements of the tumor electric field therapy devices 300, 40, 60 in different scenes, thereby improving the applicability of the tumor electric field therapy devices 300, 40, 60 in different scenes.
