Description

Technical Field

[0001] This disclosure relates to tumor treating fields (TTF) technology, and in particular to a tumor treating field device and a control method. Background Technology

[0002] Tumor electric field therapy is a treatment method that uses a low-intensity, mid-frequency (e.g., 100-300 kHz) alternating electric field to prevent the formation of spindle microtubules during mitosis in certain tumor cells, inhibit the separation of intracellular organelles during cell division, and induce apoptosis in mitotic cells, thereby achieving the therapeutic effect on tumors.

[0003] Compared to traditional cancer treatments, TTF has an innovative mechanism of action. Certain physiological characteristics of tumor cells, such as their geometry and high-frequency mitosis, make them susceptible to TTF. TTF disrupts the normal aggregation of microtubules by applying directional forces to intracellular polar particles (such as macromolecules and organelles). These processes can lead to physical damage to the cell membrane and apoptosis. During the telophase of mitosis, the morphology of the cleavage groove leads to an uneven distribution of the electric field around it. Under the influence of TTF, the electric field strength at the cleavage groove is significantly enhanced, causing charged substances in the cell to move towards the cleavage groove, interfering with or even destroying cell structure formation, ultimately leading to cell division failure and apoptosis.

[0004] In related technologies, TTF is generated and delivered to the patient via a tumor electric field therapy device. However, there is a risk of equipment malfunction during the use of this device. If the delivery of AC signals to the patient cannot be stopped in time, it may lead to abnormal burns or other dangerous situations. Therefore, it is necessary to provide a stable and safe tumor electric field therapy device and a method for establishing a tumor therapeutic electric field. Summary of the Invention

[0023] These and other aspects of this disclosure will be apparent from the embodiments described below, and will be elucidated with reference to the embodiments described below. Attached Figure Description

[0029] Figure 5 This is a schematic flowchart of a control method for an adapter of a tumor electric field therapy device according to an exemplary embodiment. Detailed Implementation

[0030] Tumor electric field therapy is a non-invasive treatment method that inhibits mitosis by delivering low-intensity, mid-frequency alternating current signals to the lesion site, thereby interfering with the mitosis of tumor cells, inhibiting tumor cell proliferation, interfering with tumor cell migration, and reducing the tumor's ability to repair DNA.

[0031] The tumor electric field therapy device mainly includes a main unit, an adapter electrically connected to the main unit for signal transmission, and electrode patches electrically connected to the main unit via the adapter. The electrode patches are applied to the skin corresponding to the lesion, thereby applying the alternating current signal generated by the signal generator in the main unit to the area where the tumor is located to achieve tumor electric field therapy.

[0032] During tumor electric field therapy, there is a risk of equipment malfunction. If the delivery of AC signals to the patient cannot be stopped in time, it may lead to burns or other dangerous situations. Existing treatment equipment typically controls the signal generator to stop outputting AC signals solely through the host control unit. This single control method is susceptible to failure in the event of a host malfunction. Therefore, to improve safety, it is necessary to implement a redundant design for the control system of the tumor electric field therapy device.

[0033] Figure 1 This is a schematic block diagram of a tumor electric field therapy device 100 according to an exemplary embodiment. Figure 1 As shown, the tumor electric field therapy device 100 includes a main unit 110, an adapter 120 electrically connected to the main unit 110, and an electrode patch 130 electrically connected to the main unit 110 through the adapter 120.

[0034] Figure 2 yes Figure 1 A schematic block diagram of the internal structure of the tumor electric field therapy device 100 is shown. Figure 2 As shown, the host 110 includes a signal generator 111 and a first controller 113. The signal generator 111 is configured to generate an AC signal. The first controller 113 is electrically connected to the signal generator 111 and can control whether the signal generator 111 generates an AC signal. When the host 110 experiences a communication failure with the adapter 120, the first controller 113 controls the signal generator 111 to stop generating an AC signal.

[0035] The adapter 120 includes a switching unit 121 and a second controller 124. The switching unit 121 is configured to receive an AC signal from a signal generator 111. The second controller 124 is electrically connected to the switching unit 121 and can control the switching unit 121 to turn on and off. When the adapter 120 is abnormally connected to at least one of the host 110 and the electrode patch 130, the second controller 124 controls the switching unit 121 to disconnect, thereby cutting off the transmission of the AC signal to the electrode patch 130.

[0036] Electrode patch 130 is configured to receive AC signals via switching unit 121 to transmit AC signals.

[0037] In the tumor electric field therapy device 100, the main unit 110 and the adapter 120 are respectively equipped with a first controller 113 and a second controller 124. The first controller 113 and the second controller 124 are independent of each other and perform corresponding control according to different abnormal situations of the tumor electric field therapy device 100 during operation. In the event of an abnormality in the tumor electric field therapy device 100, the signal generator 111 can be shut down in time or the control switch unit 121 can be used to disconnect the transmission circuit of the AC signal, so that the AC signal will not be transmitted to the electrode patch 130, thereby improving the safety of the tumor electric field therapy device 100.

[0038] In some embodiments, the first controller 113 is further configured to determine that the host 110 and the adapter 120 are in communication abnormality, wherein the communication abnormality between the host 110 and the adapter 120 includes at least one of the following: abnormal temperature of the electrode patch 130, abnormal connection between the host 110 and the adapter 120, or the host 110 does not meet the startup conditions.

[0039] In some embodiments, the adapter 120 further includes a temperature detector 123 and a second transceiver 122. The second transceiver 122 is electrically connected to the temperature detector 123. The temperature detector 123 is also electrically connected to the electrode patch 130, and can detect the temperature of the electrode patch 130 and generate a temperature signal representing the temperature of the electrode patch 130. The host 110 also includes a first transceiver 112. The first transceiver 112 is electrically connected to the first controller 113 and the second transceiver 122, respectively. The temperature signal generated by the temperature detector 123 can be transmitted to the first transceiver 112 via the second transceiver 122, so that the first controller 113 can determine whether the temperature of the electrode patch 130 is abnormal.

[0040] In some embodiments, when the first controller 113 determines that the temperature signal of the electrode patch 130 is abnormal, it filters the temperature signal representing the temperature of the electrode patch 130 and determines whether the temperature of the electrode patch 130 is abnormal based on the filtered temperature signal. When the first controller 113 determines that the temperature of the electrode patch 130 is abnormal based on the filtered temperature signal, it controls the signal generator 111 to stop generating AC signals and puts the host 110 into a standby state. In this example, the first controller 113 has a preset temperature range for the electrode patch 130, which is 0℃-50℃.

[0041] In some embodiments, the first controller 113 also presets a first threshold time. When the first controller 113 determines that the initial connection between the host 110 and the adapter 120 is abnormal, it controls the host 110 and the adapter 120 to reconnect and triggers a timeout count. If the host 110 and the adapter 120 are still abnormally connected after the preset first threshold time, the first controller 113 determines that the connection between the host 110 and the adapter 120 is abnormal, thereby controlling the signal generator 111 not to generate an AC signal and putting the host 110 into a standby state. In this example, the first threshold time is 2 seconds.

[0042] In some embodiments, when the first controller 113 determines that the start signal has not been triggered or the first controller 113 has an abnormal self-test, the first controller 113 determines that the host 110 does not meet the start conditions, thereby controlling the signal generator 111 not to generate an AC signal and putting the host 110 into a standby state.

[0043] In some embodiments, the second controller 124 is further configured to determine at least one of the following: an abnormal connection between the adapter 120 and the host 110, or an abnormal connection between the adapter 120 and the electrode patch 130.

[0044] In some embodiments, the second controller 124 has a preset second threshold time. When the second controller 124 determines that the initial connection between the adapter 120 and the host 110 is abnormal, it controls the adapter 120 to reconnect with the host 110 and triggers a timeout count. If the connection between the adapter 120 and the host 110 is still abnormal after the preset second threshold time has elapsed, the second controller 124 determines that the connection between the adapter 120 and the host 110 is abnormal, and thus controls the switch unit 121 to disconnect, so that the AC signal generated by the signal generator 111 cannot be transmitted to the electrode patch 130. In this example, the second threshold time is also 2 seconds.

[0045] In some embodiments, when the second controller 124 determines that the initial connection between the adapter 120 and the electrode patch 130 is abnormal, it filters the temperature signal representing the temperature of the electrode patch 130 and determines whether the connection between the adapter 120 and the electrode patch 130 is abnormal based on the filtered temperature signal. When it is determined based on the filtered temperature signal that the connection between the adapter 120 and the electrode patch 130 is still abnormal, the second controller 124 determines that the connection between the adapter 120 and the electrode patch 130 is abnormal, thereby controlling the switch unit 121 to open, so that the AC signal generated by the signal generator 111 cannot be transmitted to the electrode patch 130. In this example, the second controller 124 has a preset temperature range for the electrode patch 130, which is 0℃-50℃.

[0046] In summary, a first controller 113 and a second controller 124 are respectively installed inside the host 110 and the adapter 120. The first controller 113 controls whether the signal generator 111 generates an AC signal based on whether there is a communication abnormality between the host 110 and the adapter 120. The second controller 124 controls whether the switch unit 121 is disconnected based on whether there is a connection abnormality between the adapter 120 and the host 110 and whether there is a connection abnormality between the adapter 120 and the electrode patch 130. This allows the host 110 and the adapter 120 to independently control the transmission circuit of the AC signal, improving the reliability of the tumor electric field therapy device 100 and reducing the possibility of dangerous situations.

[0047] Figure 3 yes Figure 1 A schematic flowchart illustrating the control method 300 of the tumor electric field therapy device 100 is shown. Figure 3 As shown, the control method 300 includes:

[0048] In step 320, in response to determining that the communication between the host 110 and the adapter 120 is abnormal, the first controller 113 controls the signal generator 111 not to generate an AC signal;

[0049] In step 340, in response to determining that the adapter 120 is abnormally connected to at least one of the host 110 and the electrode patch 130, the second controller 124 disconnects the switching unit 121, thereby disconnecting the transmission of AC signal to the electrode patch 130.

[0050] In the tumor electric field therapy device 100, the first controller 113 in the main unit 110 independently controls whether the signal generator 111 generates an AC signal, and the second controller 124 in the adapter 120 independently controls whether the switch unit 121 is disconnected. This enables both the main unit 110 and the adapter 120 to independently control the conduction or disconnection of the communication circuit that transmits the AC signal to the electrode patch 130, thereby improving the safety of the tumor electric field therapy device 100 during use.

[0051] In some embodiments, step 310 is included before step 320. Step 310 includes: a first controller 113 determines that the communication between the host 110 and the adapter 120 is abnormal, wherein the abnormal communication between the host 110 and the adapter 120 includes at least one of the following: abnormal temperature of the electrode patch 130, abnormal connection between the host 110 and the adapter 120, or the host 110 does not meet the start-up conditions.

[0052] In some embodiments, step 330 is included before step 340, and step 330 includes: the second controller 124 determining at least one of the following: the adapter 120 is not properly connected to the host 110, or the adapter 120 is not properly connected to the electrode patch 130.

[0053] Although the operations are depicted in the accompanying drawings in a specific order, this should not be construed as requiring that these operations be performed in the specific order shown or in chronological order, nor should it be construed as requiring that all the operations shown be performed to obtain the desired result. For example, step 340 may be performed before or concurrently with step 320, and step 330 may be performed before or concurrently with step 310.

[0054] Figure 4 This is a schematic flowchart illustrating the control method of the main unit 110 of the tumor electric field therapy device 100. In some embodiments, please refer to... Figure 4 After power is connected, the host 110 loads its operating environment (loading the operating system, file system, etc.), performs hardware initialization (e.g., ADC, serial port, PWM, DAC, etc.), and establishes connections with the adapter 120 and electrode patch 130. The first controller 113 determines whether the host 110 meets the startup conditions. When the host 110 does not meet the startup conditions, the first controller 113 controls the signal generator 111 not to generate an AC signal. The host 110 not meeting the startup conditions includes at least one of the following: the startup signal is not triggered or the first controller 113 fails a self-test. The first controller 113 determines whether to trigger the startup signal. If the startup signal is not triggered, the first controller 113 controls the signal generator 111 not to generate an AC signal, and the host 110 is in standby mode. If the startup signal is triggered, the first controller 113 performs a self-test. If the self-test fails, the first controller 113 controls the signal generator 111 not to generate an AC signal, and the host 110 remains in standby mode.

[0055] When the start signal is triggered and the first controller 113 performs a normal self-test, the host 110 is ready to start. The first controller 113 further determines whether the connection between the host 110 and the adapter 120 is abnormal. When the connection between the host 110 and the adapter 120 is abnormal, the first controller 113 controls the signal generator 111 not to generate an AC signal, and the host 110 is in standby mode.

[0056] In some embodiments, the first controller 113 also presets a first threshold time. When the connection between the host 110 and the adapter 120 is abnormal, the first controller 113 controls the host 110 to reconnect with the adapter 120 and triggers a timeout count. If the connection between the host 110 and the adapter 120 still fails after the preset first threshold time, the first controller 113 controls the signal generator 111 not to generate an AC signal, and the host 110 is in a standby state. When the host 110 and the adapter 120 successfully reconnect within the preset first threshold time, the first controller 113 re-determines whether the connection between the host 110 and the adapter 120 is abnormal. In this example, the first threshold time is 2 seconds.

[0057] When the host 110 and adapter 120 are properly connected, the first controller 113 controls the signal generator 111 to generate an AC signal and determines whether the temperature of the electrode patch 130 is abnormal. When the temperature of the electrode patch 130 is normal, the first controller 113 controls the signal generator 111 to continue generating an AC signal and re-determines whether to trigger the start signal. When the temperature of the electrode patch 130 is abnormal, the first controller 113 controls the signal generator 111 to stop generating an AC signal, and the host 110 enters standby mode.

[0058] In some embodiments, when the temperature of the electrode patch 130 is abnormal, the first controller 113 filters the temperature signal representing the temperature of the electrode patch 130 and determines whether the temperature of the electrode patch 130 is abnormal based on the filtered temperature signal. When the filtered temperature signal determines that the temperature of the electrode patch 130 is abnormal, the first controller 113 controls the signal generator 111 to stop generating AC signals, causing the host 110 to enter a standby state. When the filtered temperature signal determines that the temperature of the electrode patch 130 is normal, the first controller 113 re-determines whether the temperature of the electrode patch 130 is abnormal. In this example, the first controller 113 has a preset temperature range for the electrode patch 130, which is 0℃-50℃.

[0059] Figure 5 This is a schematic flowchart illustrating the control method of the adapter 120 of the tumor electric field therapy device 100. In some embodiments, please refer to... Figure 5 After power is connected, the adapter 120 loads its operating environment (operating system), performs hardware initialization (ADC, serial port, GPIO, etc.), and establishes connections with the host 110 and electrode patch 130. The second controller 124 determines whether the connection between the adapter 120 and the host 110 is abnormal. When the connection between the adapter 120 and the host 110 is abnormal, the second controller 124 controls the switch unit 121 to disconnect, preventing the AC signal generated by the signal generator 111 from being transmitted to the electrode patch 130.

[0060] In some embodiments, the second controller 124 has a preset second threshold time. When the connection between the adapter 120 and the host 110 is abnormal, the second controller 124 controls the adapter 120 to reconnect with the host 110 and triggers a timeout count. If the adapter 120 still fails to connect with the host 110 after the preset second threshold time, the second controller 124 controls the switch unit 121 to disconnect, preventing the AC signal generated by the signal generator 111 from being transmitted to the electrode patch 130. When the adapter 120 successfully reconnects with the host 110 within the preset second threshold time, the second controller 124 re-determines whether the connection between the adapter 120 and the host 110 is abnormal. In this example, the second threshold time is also 2 seconds.

[0061] When the adapter 120 is properly connected to the host 110, the second controller 124 determines whether the connection between the adapter 120 and the electrode patch 130 is abnormal. When the connection between the adapter 120 and the electrode patch 130 is normal, the second controller 124 controls the switch unit 121 to close, allowing the AC signal generated by the signal generator 111 to be transmitted to the electrode patch 130, and re-determines whether the connection between the adapter 120 and the host 110 is abnormal. When the connection between the adapter 120 and the electrode patch 130 is abnormal, the second controller 124 controls the switch unit 121 to open, preventing the AC signal generated by the signal generator 111 from being transmitted to the electrode patch 130.

[0062] In some embodiments, when the connection between the adapter 120 and the electrode patch 130 is abnormal, the second controller 124 filters the temperature signal representing the temperature of the electrode patch 130 and determines whether the connection between the adapter 120 and the electrode patch 130 is abnormal based on the filtered temperature signal. When the connection between the adapter 120 and the electrode patch 130 is determined to be abnormal based on the filtered temperature signal, the second controller 124 controls the switch unit 121 to open, preventing the AC signal generated by the signal generator 111 from being transmitted to the electrode patch 130. When the connection between the adapter 120 and the electrode patch 130 is determined to be normal based on the filtered temperature signal, the second controller 124 re-determines whether the connection between the adapter 120 and the electrode patch 130 is abnormal. In this example, the second controller 124 has a preset temperature range for the electrode patch 130, which is 0℃-50℃.
