[0068] Research has found that most vital signs of organisms are monitored in real time via electrical signals. Pulsed electric field therapy, as an emerging treatment method, has shown advantages in the field of life and health. However, strong pulsed electric fields can directly affect the accuracy of real-time monitoring equipment and even cause damage to the equipment. Existing methods all achieve anti-interference by switching circuits, isolating and grounding, or adding passive suppression devices, but these methods have the problems of introducing new strong field coupling loops and difficulty in bidirectional signal transmission.
[0069] Currently, most pulse generating devices and real-time monitoring devices are directly electrically connected to the target organism. This will create a strong field coupling interference loop between the pulse generating device, the real-time monitoring device, and the target organism during the pulse action, causing damage to the pulse generating device and / or the real-time monitoring device.
[0070] Further research revealed that adding a passive interference suppression device between the real-time monitoring device and the target organism, and another between the real-time monitoring device and the pulse generating device, can relatively suppress the formation of a strong field coupling interference loop between the pulse generating device, the real-time monitoring device, and the target organism. However, since passive interference suppression devices are typically high-frequency suppression coils, their suppression capability is limited, only effective against specific frequency bands and amplitudes, making it difficult to achieve effective suppression in strong field pulse environments.
[0071] Adding an active switching device between the real-time monitoring device and the target organism, and between the real-time monitoring device and the pulse generating device, can suppress most interference. However, since the active switching device is directly electrically connected to both the pulse generating device and the pulse generating device, coupling loops will be formed between the two active switching devices and the real-time monitoring device, and between the active switching device, the pulse generating device, and the target organism. This will cause severe electrical pulse interference under high current or instantaneous discharge conditions, leading to malfunction or crash of the monitoring device.
[0072] This application provides a signal processing apparatus, system, and method, aiming to solve the aforementioned technical problems of the prior art. To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.
[0073] This application provides a pulse generation system, see [link to relevant documentation]. Figure 1 As shown, the pulse generation system 1 includes at least two first electrodes 400, at least two second electrodes 500, and a signal processing system 10.
[0074] See Figure 1 As shown, the signal processing system 10 includes: a pulse generator 300, a monitoring device 200, and a signal processing device 100.
[0075] See Figure 1 As shown, the signal processing device 100 includes a control unit 110, a signal conversion unit 120, and a switching unit 130.
[0076] See Figure 1As shown, each first electrode 400 is electrically connected to the switching unit 130 of the signal processing device 100, and is used to electrically connect or disconnect each first electrode 400 from the monitoring device 200 when the switching unit 130 is turned on or off.

Each second electrode 500 can be an ablation needle that can be inserted into the target biological tissue to ablate the target biological tissue. Each second electrode 500 can also be an electrode patch for ablating the target biological tissue.

[0080] Optionally, the control unit 110 is used to control the pulse generator 300 to output a pulse signal based on the bioelectric signal output by the monitoring device 200.
[0081] Optionally, the bioelectrical signal includes electrocardiogram (ECG) waveform signals or electroencephalogram (EEG) signals. The target object can be the human body, and the target biological tissue can be tumor cells. The monitoring device 200 can correspond to an ECG signal acquisition device for monitoring ECG waveform signals, a pulse oximeter for monitoring bioelectrical signals such as blood oxygen, and an EEG monitor for monitoring EEG signals.
[0082] This application provides a signal processing device, see [link to relevant documentation]. Figure 1 As shown, the signal processing device 100 includes: a control unit 110, a signal conversion unit 120, and a switching unit 130.
[0083] The control unit 110 is configured to communicate with both the monitoring device 200 and the pulse generator 300.
[0084] The control unit 110 transmits signals to the switching unit 130 through the signal conversion unit 120.
[0085] The switching unit 130 is configured to be electrically connected to the monitoring device 200 and each of the first electrodes 400; each of the first electrodes 400 is used to be attached to the surface of the target object according to a first design.
[0086] The signal conversion unit 120 is used to convert the control signal output by the control unit 110 into an electrical signal and output it to the switching unit 130 to control the switching unit 130 to turn on and off. The control signal is one of the following: sound signal, light signal, and magnetic signal.
[0087] Alternatively, the control signal output by the control unit 110 can be converted into a first conversion signal, and the first conversion signal can be converted into an electrical signal and output to the switch unit 130 to control the switching unit 130 to turn on and off. The control signal is an electrical signal, and the first conversion signal is one of an acoustic signal, an optical signal, and a magnetic signal.
[0088] Optionally, the signal conversion unit 120 is located between the control unit 110 and the switching unit 130, so that there is no electrical connection between the control unit 110 and the switching unit 130 for signal transmission.
[0089] Optionally, when the control signal output by the control unit 110 is one of an acoustic signal, an optical signal, and a magnetic signal, the control unit 110 includes a first signal conversion module. The first signal conversion module is used to convert the electrical signal to be output by the control unit into one of the acoustic signal, optical signal, and magnetic signal. In this case, the signal conversion unit 120 needs to convert the control signal into an electrical signal that can control the switching unit 130 to be turned on and off, that is, to convert the acoustic signal, optical signal, or magnetic signal into an electrical signal.
[0090] Optionally, the control signal output by the control unit 110 is an electrical signal, and the signal conversion unit 120 needs to convert the control signal into an acoustic signal, an optical signal, or a magnetic signal, and then convert the acoustic signal, optical signal, or magnetic signal into an electrical signal accordingly.
[0091] In this embodiment, the control unit 110 transmits signals through the signal conversion unit 120 and the switching unit 130. The signal conversion unit 120 can convert acoustic, optical, and magnetic signals into electrical signals, or convert electrical signals into acoustic, optical, and magnetic signals, and then convert the acoustic, optical, and magnetic signals back into electrical signals. This avoids the monitoring device 200 and the pulse generator 300 from being directly electrically connected to the target object, thus preventing the formation of a strong field coupling loop. In this embodiment, a signal processing device 100 is added to the pulse generator system 1. Through signal conversion between the control unit 110, the signal conversion unit 120, and the switching unit 130, the control unit 110 and the switching unit 130 are not directly electrically connected to transmit signals. This is equivalent to disconnecting the electrical connection between the control unit 110 and the switching unit 130 through the signal conversion unit 120, thereby preventing a strong field coupling loop, protecting the monitoring device 200, and preventing damage to the monitoring device.
[0092] In some embodiments, see Figure 1As shown, the control unit 110 is used to output a control signal to the signal conversion unit 120 according to whether the pulse generator 300 outputs a pulse signal, so as to control the switching unit 130 to turn on and off, and control the monitoring device 200 to turn on and off with each first electrode 400.
[0093] Optionally, in this embodiment of the application, the switching unit 130 can be turned on and off according to whether the pulse generator 300 outputs a pulse signal, so as to avoid the pulse signal output by the pulse generator 300 affecting the bioelectric signal collected by the monitoring device 200.
[0094] In some embodiments, see Figure 1 As shown, the control unit 110 is used to output a first control signal to the signal conversion unit 120 when the pulse generator 300 outputs a pulse signal, so that the signal conversion unit 120 outputs a first level signal to the switch unit 130 based on the first control signal, and controls the switch unit 130 to open; when the pulse generator 300 stops outputting a pulse signal, it outputs a second control signal to the signal conversion unit 120, so that the signal conversion unit 120 outputs a second level signal to the switch unit 130 based on the second control signal, and controls the switch unit 130 to turn on, and the monitoring device 200 collects the bioelectric signals output by each first electrode 400.
[0095] Optionally, the first level signal and the second level signal are two opposite level signals.
[0096] In this embodiment, when the pulse generator 300 outputs a pulse signal, the switching unit 130 is disconnected, and the electrical connection between each first electrode 400 and the monitoring device 200 is broken. The pulse generator 300 can then normally output pulse signals to the target biological tissue for ablation. Simultaneously, when the pulse generator 300 stops outputting pulse signals, the switching unit 130 is turned on, and each first electrode 400 outputs bioelectrical signals to the monitoring device 200. This achieves the goal of shielding the pulse signal during bioelectrical signal acquisition, thus preventing interference from the pulse signal and making the acquired bioelectrical signals more accurate.
[0097] In some embodiments, see Figure 3 and Figure 4 As shown, the signal processing device 100 further includes a first signal transceiver unit 140.
[0098] The first signal transceiver unit 140 is used to convert the first signal output by the monitoring device 200 into a second signal and output it to the control unit 110; or, convert the third signal output by the control unit 110 into a fourth signal and output it to the monitoring device 200.

[0104] The second and third conversion signals are both optical or acoustic signals, while the fifth, sixth, seventh, and eighth signals are all electrical signals.
[0105] Optionally, both the monitoring device 200 and the control unit 110 output and receive electrical signals.

[0128] Alternatively, the NOT gate 1311 can also be an inverter or a reverse circuit, which works on the same principle and is also within the scope of protection of this application.
[0129] As an example, see Figure 5 As shown, IN+ is the control signal, IN- is grounded by default, NET2_IN is the signal input terminal electrically connected to each first electrode 400, and NET2_OUT is the signal output terminal electrically connected to the monitoring device 200. The NOT gate circuit 1311 represents the NOT gate chip M1, the first switch submodule 1312 includes the switch device T1, and the second switch submodule 1313 includes the switch device T2.
