[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0033] This invention provides an ultrasonic generator that can be used to stimulate cells in cell experiments, i.e., to stimulate cells by emitting ultrasonic signals to a cell culture plate. Figure 1 This is a structural schematic diagram of an ultrasonic generator provided in an embodiment of this utility model, for reference. Figure 1 The ultrasonic generator includes an ultrasonic controller 100 and an ultrasonic generator 200; the ultrasonic generator 200 includes at least two transducers 210 of different frequencies, and the ultrasonic generator includes multiple output zones A1, each output zone A1 being provided with at least one transducer 210; during the same ultrasonic generation process, the transducers 210 corresponding to all output zones A1 have the same frequency.
[0034] The ultrasonic controller 100 is connected to the ultrasonic generator 200. The ultrasonic controller 100 is configured to acquire the current frequency of the transducer 210 and receive input commands. Based on the input commands, it determines the target output area and the target parameters of the ultrasonic signal output by the ultrasonic generator. It then controls the ultrasonic generator 200 to output the ultrasonic signal to the target output area according to the current frequency and the target parameters. The target parameters include at least one of the target duty cycle, target frequency, and target intensity of the ultrasonic signal.
[0035] The transducer 210 is an electronic component capable of energy conversion. The ultrasonic generator 200 can output ultrasonic signals through the transducer 210. The output area A1 of the ultrasonic generator is equipped with at least one transducer 210. A cell culture plate can be placed on the transducer 210 in each output area A1, so that the ultrasonic signals output by the transducer 210 stimulate the cells on the cell culture plate, thereby conducting cell experiments. One well of the cell culture plate corresponds to one output area A1, and each well of the cell culture plate can contain cells. For example, the ultrasonic generator includes six output areas A1, which can be adapted to a six-well bidirectional stress cell culture plate. Alternatively, the output area A1 of the ultrasonic generator may have four transducers 210, so that each position in the well area of the cell culture plate can be stimulated by ultrasonic signals, which helps improve the accuracy and reliability of cell experiments. The ultrasonic controller 100 can be connected to the transducer 210, thereby outputting a pulse width modulation signal to the transducer 210. When the transducer 210 is excited by the electrical signal (pulse width modulation signal), the material of the transducer 210 undergoes periodic mechanical deformation. This mechanical vibration propagates in the medium, forming an ultrasonic signal. Therefore, by outputting the pulse width modulation signal to the transducer 210, the ultrasonic controller 100 can control whether each transducer 210 outputs an ultrasonic signal, and control the parameters of the ultrasonic signal output by each transducer 210 (including at least one of duty cycle, frequency, and intensity).
[0036] Specifically, by configuring the ultrasound generator 200 to include at least two different frequency transducers 210, and ensuring that the frequency of the transducers 210 corresponding to all output areas A1 is the same during the same ultrasound generation process, different frequency transducers 210 can be replaced as needed during cell experiments. This adapts to different experimental requirements, enhances the flexibility and applicability of the ultrasound generator, facilitates repeatability, and improves the reliability and accuracy of the experiments. For example, different types of transducers 210 may include transducers with a working frequency of 1MHz, 1.5MHz, and 2MHz, or other frequencies, depending on the specific requirements. This embodiment does not impose limitations. Thus, the ultrasound generator of this embodiment can meet the needs of different experimental conditions, improving the flexibility and accuracy of the experiments.
[0037] It should be noted that when replacing transducers 210 of different frequencies, they can be replaced manually or by connecting different frequency transducers 210 via switches. The connection of the corresponding transducer 210 to the ultrasonic controller 100 is controlled by turning the switches corresponding to different frequency transducers 210 on or off, thus selecting the transducer 210 connected to the ultrasonic generator 200 and achieving automatic replacement of the transducer 210. The control of turning the switches corresponding to different frequency transducers 210 on or off can be manual or controlled by the ultrasonic controller 100.
[0038] Furthermore, the ultrasonic controller 100 can acquire the current frequency of the transducer 210 and control the target pulse width modulation signal output to the transducer 210 according to the current frequency, thereby matching the frequency of the target pulse width modulation signal output to the transducer 210 with the current frequency of the transducer 210, so that the transducer 210 works in the best state, achieving efficient energy conversion and optimized signal transmission path, ensuring that ultrasonic energy is efficiently transferred to the experimental sample and improving the experimental effect.
[0039] The device may include a detection module, which includes a detection circuit. The detection circuit can detect the current frequency of the transducer 210 and send it to the ultrasonic controller 100, so that the ultrasonic controller 100 can obtain the current frequency of the transducer 210.
[0040] The ultrasonic controller 100 may include a processing chip. The ultrasonic controller 100 may also include analog circuitry, such as a pulse signal generation circuit and a frequency adjustment module. The pulse signal generation circuit may include a comparator, whose input terminals can receive a triangular wave signal and a DC voltage. By comparing the triangular wave signal and the DC voltage, a pulse width modulation (PWM) signal is output. The triangular wave signal can be generated by a counter. The frequency adjustment module may be a voltage conversion module. The frequency adjustment module can adjust the output voltage based on the current frequency of the transducer 210 detected by the detection circuit. That is, it can adjust the DC voltage input to the comparator, thereby adjusting the PWM signal output by the pulse signal generation circuit, and ultimately outputting the target PWM signal. Furthermore, adjusting the DC voltage input to the comparator can adjust the duty cycle of the PWM signal output by the comparator. The ultrasonic controller 100 may also include a power amplifier circuit. By adjusting the amplification factor of the power amplifier circuit, the intensity of the PWM signal can be adjusted. This embodiment is not limited to any particular model.
[0041] Furthermore, the input command can include target parameters and a target output area. The ultrasonic controller 100 can receive the input command, determine the target parameters of the target output area and the ultrasonic signal output by the ultrasonic generator based on the input command, and control the ultrasonic generator 200 to output the ultrasonic signal with the target parameters to the target output area according to the current frequency and target parameters. This allows control over whether each output area A1 outputs an ultrasonic signal, and over at least one of the intensity, duty cycle, and frequency of the ultrasonic signal output by each output area A1. This satisfies the needs of different experimental conditions, improving the flexibility and accuracy of the experiment. Each output area A1 can be independently adjusted according to different experimental requirements, ensuring the reliability and repeatability of the experimental results.
[0042] The technical solution of this embodiment, by setting the ultrasound generator to include at least two transducers of different frequencies, ensures that the frequency of the transducers corresponding to all output areas is the same during the same ultrasound generation process. Therefore, during cell experiments, transducers of different frequencies can be replaced as needed to adapt to different experimental requirements, thereby improving the flexibility and applicability of the ultrasound generator, facilitating repeatability, and enhancing the reliability and accuracy of the experiments. Thus, the ultrasound generator of this embodiment can meet the needs of different experimental conditions, improving the flexibility and precision of experiments.
[0043] Optionally, refer to Figure 1 The ultrasonic generator 200 also includes a flexible circuit board 201;
[0044] The transducer 210 is located on the flexible circuit board 201 and is electrically connected to the flexible circuit board 201. The flexible circuit board 201 is connected to the ultrasonic controller 100 through the pluggable interface 202.
[0045] Specifically, the transducer 210 can be soldered onto the flexible circuit board 201, making the transducer 210 electrically connected to the flexible circuit board 201. Furthermore, the flexible circuit board 201 is connected to the ultrasonic controller 100 via a pluggable interface 202. When replacing the transducer 210 with different frequencies, replacement can be achieved directly by plugging and unplugging through the pluggable interface 202, facilitating the replacement of transducers 210 with different frequencies to adapt to different experimental needs. The flexible circuit board 201 and the pluggable interface 202 can be connected via a connecting wire or other circuitry; no limitation is made here.
[0046] Based on the above technical solutions, Figure 2 This is a circuit structure diagram of an ultrasonic generator provided by an embodiment of the present invention. Optionally, refer to... Figure 2 The ultrasound controller 100 includes a first processing chip 110 and multiple processing modules 120; each processing module 120 corresponds to an output area A1.
[0047] The first processing chip 110 is connected to each processing module 120. The first processing chip 110 is configured to acquire the current frequency of the transducer 210, receive input instructions, and send the current frequency and input instructions to the processing module 120. The processing module 120 is configured to determine the target parameters of the target output area and the ultrasonic signal output by the ultrasonic generator based on the input instructions, and output the target pulse width modulation signal to the transducer 210 of the corresponding output area according to the current frequency and target parameters.
[0048] The first processing chip 110 is the main control chip. The first processing chip 110 may include a microcontroller chip, an ARM chip (such as an STM32 series chip), a digital signal processing (DSP) chip, or a field programmable gate array (FPGA).
[0049] Specifically, the processing module 120 can determine the target parameters of the ultrasonic signal output by the ultrasonic generator and the target output area based on the input command, and output the target pulse width modulation signal to the transducer 210 of the corresponding output area according to the current frequency and target parameters. The processing module 120 corresponds one-to-one with the output area A1, so the ultrasonic signal corresponding to each output area A1 can be controlled individually. That is, each output area A1 can be independently adjusted according to different experimental requirements to ensure the reliability and repeatability of the experimental results.
[0050] Each processing module 120 corresponds to one output area A1, meaning that one processing module 120 corresponds to one output channel. Thus, each output area A1 can be connected through an independent channel, and the parameters of the ultrasonic signal in each output area A1 can be adjusted independently.
[0051] Based on the above technical solutions, optionally, refer to Figure 2 The processing module 120 includes a second processing chip 121, an amplification control unit 122, and an amplifier 123;
[0052] The second processing chip 121 is connected to the first processing chip 110 and to the amplification control unit 122; the second processing chip 121 is configured to adjust the amplification factor output by the amplification control unit 122 according to the target parameters.
[0053] Amplifier 123 is connected to the second processing chip 121 and the amplification control unit 122 respectively. The second processing chip 121 is configured to output an initial pulse width modulation signal to amplifier 123 according to the current frequency and target parameters. The amplifier is configured to amplify the electrical parameters of the initial pulse width modulation signal according to the amplification factor output by the amplification control unit 122, and output the target pulse width modulation signal to the transducer 210 of the corresponding output area A1.
[0054] The second processing chip 121 is a slave control chip, which may include a microcontroller chip, an ARM chip (such as an STM32 series chip), a digital signal processing (DSP) chip, or a field-programmable gate array (FPGA). The input terminal of the amplification control unit 122 can be connected to an input power supply and convert the input power supply, such as by stepping down or stepping up. The voltage output by the amplification control unit 122 is transmitted to the amplifier 123 as the amplification factor, which can control the amplification factor of the amplifier 123. The second processing chip 121 can adjust the amplification factor output by the amplification control unit 122 according to the target parameters. The amplifier 123 can amplify the electrical parameters of the initial pulse width modulation signal, such as the voltage amplitude or power of the initial pulse width modulation signal.
[0055] Specifically, the second processing chip 121 can output an initial pulse width modulation (PWM) signal based on the current frequency and target parameters. For example, it can determine the frequency and / or duty cycle of the output initial PWM signal based on the current frequency and target parameters. Furthermore, it can adjust the amplification factor output by the amplification control unit 122 according to the target parameters, so that the amplifier 123 amplifies the electrical parameters of the initial PWM signal according to the amplification factor output by the amplification control unit 122. This ensures that the frequency of the target PWM signal ultimately output by the ultrasonic controller 100 matches the current frequency of the transducer 210, the intensity of the target PWM signal matches the target intensity in the target parameters, and the duty cycle of the target PWM signal matches the target duty cycle in the target parameters. This improves the efficiency of the ultrasonic signal output by the transducer 210, and the output ultrasonic signal meets the requirements. Thus, the parameters of the ultrasonic signal output by the transducer 210 based on the target PWM chip are the target parameters, allowing the transducer 210 to control the ultrasonic signal output according to requirements.
[0056] In some implementations, the input command may include a target output region and corresponding target parameters. The target parameters include target intensity (or target voltage amplitude) and target duty cycle. Based on the target parameters in the input command, the duty cycle and intensity of the target pulse width modulation signal can be adjusted, thereby achieving adjustment of the duty cycle and intensity of the ultrasonic signal. The frequency of the target pulse width modulation signal can be adjusted based on the current frequency of the transducer 210, so that the frequency of the target pulse width modulation signal matches the current frequency of the transducer 210.
[0057] Optionally, the first processing chip 110 and the second processing chip 121 can transmit signals via SPI (Serial Peripheral Interface) communication.
[0058] The second processing chip 121 and the amplification control unit 122 can transmit signals via I2C communication.
[0059] Optionally, the amplification control unit 122 includes a buck-boost chip 1221;
[0060] The input terminal of the buck-boost chip is connected to the input power supply V1, the control terminal of the buck-boost chip 1221 is connected to the second processing chip 121, and the output terminal of the buck-boost chip 1221 is connected to the amplifier 123.
[0061] Specifically, since the buck-boost chip 1221 is a controllable buck-boost chip, the output voltage of the buck-boost chip 1221 can be controlled by the second processing chip 121, that is, the amplification factor of the buck-boost chip 1221. Thus, the amplification factor of the buck-boost chip 1221 can be controlled according to the target parameters, thereby controlling the target pulse width modulation signal output by the ultrasonic controller 100, and then controlling the ultrasonic signal output by the transducer 210.
[0062] Based on the above technical solutions, optionally, refer to Figure 2 The ultrasonic controller 100 also includes a display screen 130;
[0063] The display screen 130 is connected to the first processing chip 110. The display screen 130 is configured to receive input commands and transmit the input commands to the first processing chip 110. The first processing chip 110 is also configured to acquire the output status of each output area A1 and the actual parameters of the ultrasonic signal generated by the transducer 210, and send the output status and actual parameters to the display screen 130. The display screen 130 is also configured to display the output status and actual parameters.
[0064] The display screen 130 can be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen; this embodiment is not limited to either. The output status of each output area A1 can include whether the transducer 210 in output area A1 is outputting ultrasonic signals normally, i.e., whether output area A1 is outputting ultrasonic signals normally. The display screen 130 can be connected to the first processing chip 110 via a serial port connection.
[0065] Specifically, by setting up a display screen 130, which displays the output status of each output zone A1 and the actual parameters of the ultrasonic signal generated by the transducer 210, real-time monitoring can be performed to ensure the transparency and controllability of the experimental process. Furthermore, it allows experimenters to adjust experimental parameters in real time based on the output status of each output zone A1 and the actual parameters of the ultrasonic signal generated by the transducer 210, ensuring the accuracy and reliability of the experiment. For example, input commands can be entered through the display screen 130, which transmits the input commands to the first processing chip 110. The first processing chip 110 then transmits the input commands to the processing module 120, enabling the processing module to determine the target output zone and the target parameters of the ultrasonic signal based on the input commands, thereby achieving control over each output zone A1.
[0066] Table 1 is a schematic table of the display content of the display screen. Table 1 shows the display content of the display screen 130. When the display screen 130 actually displays, it can be displayed in the form of an interface or in the form of a table. This embodiment does not limit it.
[0067] Table 1. Illustration of Display Contents on the Screen
[0068] Voltage (V) 12.0 12.0 12.0 <![CDATA[Intensity (mW / cm 2 )]]> 576.0 576.0 576.0 Duty cycle (%) 100 100 100 CH4 CH5 CH6 Voltage (V) 12.0 12.0 12.0 <![CDATA[Intensity (mW / cm 2 )]]> 576.0 576.0 576.0 Duty cycle (%) 100 100 100
[0069] For example, an ultrasonic generator includes six output zones: the first, second, third, fourth, fifth, and sixth output zones. As shown in Table 1, CH1 represents the first channel, which is the output channel of the transducer 210 in the first output zone; CH2 represents the second channel, which is the output channel of the transducer 210 in the second output zone; CH3 represents the third channel, which is the output channel of the transducer 210 in the third output zone; CH4 represents the fourth channel, which is the output channel of the transducer 210 in the fourth output zone; CH5 represents the fifth channel, which is the output channel of the transducer 210 in the fifth output zone; and CH6 represents the sixth channel, which is the output channel of the transducer 210 in the sixth output zone. Voltage refers to the actual voltage value of the ultrasonic signal, intensity refers to the actual intensity of the ultrasonic signal, and duty cycle refers to the actual duty cycle of the ultrasonic signal.
[0070] The display screen 130 can also display the output status of each channel (i.e., each output area A1) via indicator lights, and can also display the duration of the output ultrasonic signal (i.e., running time), thus enabling timing of the experiment. The display screen 130 can also display the current time. Furthermore, the display screen 130 can indicate whether the first processing chip 110 is connected to the display screen 130, or whether the first processing chip 110 is connected to the terminal device, etc.
[0071] For example, the display screen 130 can be equipped with multiple duty cycle adjustment bars and multiple voltage amplitude adjustment bars. For instance, each output area A1 corresponds to one duty cycle adjustment bar and one voltage amplitude adjustment bar. By sliding the duty cycle adjustment bar, the target duty cycle can be input, and by sliding the voltage amplitude adjustment bar, the target voltage amplitude can be input, i.e., the target intensity can be input, thereby inputting the target parameters.
[0072] Based on the above technical solutions, Figure 3 This is a circuit structure diagram of another ultrasonic generator provided in an embodiment of the present invention. Optionally, refer to... Figure 3 The ultrasound controller 100 also includes a Bluetooth module 140;
[0073] The first processing chip 110 is connected to the Bluetooth module 140. The first processing chip 110 is configured to communicate with the terminal device through the Bluetooth module 140 and obtain update instructions through the Bluetooth module 140.
[0074] The Bluetooth module 140 may include a Bluetooth communication chip. The terminal device may include a mobile phone, computer, or host computer, etc.
[0075] Specifically, by setting up a Bluetooth module 140, the first processing chip 110 can communicate with the terminal device through the Bluetooth module 140. Thus, the first processing chip 110 can receive input commands through the Bluetooth module 140, and the terminal device can also obtain the status of each output area A1 and the actual parameters of the corresponding output ultrasonic chip from the first processing chip 110 through the Bluetooth module 140, thereby realizing real-time monitoring.
[0076] Furthermore, the first processing chip 110 can obtain update commands via the Bluetooth module 140, and the software inside the first processing chip 110 can be updated and upgraded according to the update commands. It supports remote Bluetooth upgrades, allowing for the acquisition of the latest software updates and functional improvements at any time. This not only simplifies the device maintenance and upgrade process but also ensures that the first processing chip 110 can obtain the latest technical support and functional optimizations in a timely manner. This avoids the problem in related technologies where device function upgrades typically require returning to the manufacturer for hardware updates, which is inconvenient for users, wastes time and money, and affects the long-term use of the device.
[0077] Optionally, refer to Figure 3 The ultrasonic controller 100 also includes a storage module 150;
[0078] The first processing chip 110 is connected to the storage module 150. The first processing chip 110 is configured to transmit the current frequency, target parameters, and the time corresponding to the target parameters to the storage module 150.
[0079] Specifically, the storage module 150 includes a memory. The first processing chip 110 is configured to transmit the current frequency, target parameters, and the corresponding time to the storage module 150, enabling the storage module 150 to record detailed information for each operation, facilitating review and management. This allows for the automatic recording of specific parameters and time for each operation, aiding in subsequent data analysis and experimental result verification.

[0081] The matching module 220 is connected between the pluggable interface 202 and the flexible circuit board 201.
[0082] Specifically, the matching module 220 includes an impedance matching circuit for impedance matching. The impedance matching circuit may include capacitors and inductors, and a suitable matching circuit type can be selected based on factors such as the operating frequency and power requirements of the transducer 210. By configuring the matching module 220, the transducer 210 can obtain maximum power from the control signal output by the ultrasonic controller 100, thereby improving circuit efficiency.
[0083] Optionally, refer to Figure 3 The ultrasonic generator 200 also includes a detection module 230;
[0084] The detection module 230 is connected to the ultrasonic controller 100. The detection module 230 is configured to detect the current frequency of the transducer 210 and transmit the current frequency to the ultrasonic controller 100.
[0085] The detection module 230 can be connected to the ultrasonic controller 100 via the pluggable interface 202.
[0086] Specifically, the detection module 230 may include a detection resistor, for example, one detection resistor for each transducer 210. By obtaining the resistance value of the detection resistor, the current frequency of the transducer 210 can be determined, thereby knowing the frequency operating range of the transducer 210. The current frequency is transmitted to the ultrasonic controller 100, which outputs a control signal based on the current frequency, thereby matching the frequency of the control signal (target pulse width modulation signal) output by the ultrasonic controller 100 with the current frequency of the transducer 210, thus ensuring optimal experimental results.
[0087] For example, the operation procedure of an ultrasonic generator may include the following steps:
[0088] Step a1: Start the ultrasonic generator. Specifically, connect the power supply, start the ultrasonic generator, and the ultrasonic controller 100 and ultrasonic generator 200 will begin self-testing.
[0089] Step a2: Select the target output area and target parameters. Specifically, according to the experimental requirements, input commands are entered through the display screen 130. The input commands include the target input area and target parameters.
[0090] Step a3: Intelligent frequency identification. Specifically, after connecting the ultrasonic controller 100 to the ultrasonic generator 200, the ultrasonic controller 100 automatically identifies the current frequency of the transducer, so that the ultrasonic controller 100 outputs a target pulse width modulation signal to the transducer 210 according to the current frequency and target parameters.
[0091] Step a4: Real-time monitoring. Specifically, during the experiment, the status of each output zone A1 and the current parameters of the corresponding ultrasonic signal can be monitored in real time through the display screen 130, ensuring the transparency and controllability of the experimental process.
[0092] Step a5: Record experimental data. Specifically, the storage module 150 can record the target parameters and time of the ultrasonic signal for each operation, facilitating subsequent data analysis and verification of experimental results.
[0093] Step a6: Complete the experiment. Specifically, after the experiment, the target parameters and time of the ultrasound signal for each operation can be obtained from the storage module 150, the experimental data of the cells can be acquired, the experimental data can be saved, and the ultrasound generator can be turned off.
[0094] During the experiment, steps a2-a5 can be repeated to complete experiments with various parameters.
[0095] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
