[0038] An embodiment of the present invention provides an ultrasonic generator, which can be applied to the stimulation of cells in cell experiments, that is, by emitting ultrasonic signals to a cell culture plate to achieve the stimulation of cells. Figure 1 is a schematic structural diagram of an ultrasonic generator provided by an embodiment of the present invention. Refer to Figure 1 , the ultrasonic generator includes: an ultrasonic controller 100 and an ultrasonic generator 200; the ultrasonic generator 200 includes at least two different frequency transducer chips 210, the ultrasonic generator includes a plurality of output areas A1, and at least one transducer chip 210 is provided in each output area A1; during the same ultrasonic generation process, the frequencies of the transducer chips 210 corresponding to all output areas A1 are the same;

[0039] The ultrasonic controller 100 is connected to the ultrasonic generator 200. The ultrasonic controller 100 is used to obtain the current frequency of the transducer chip 210, receive an input instruction, determine a target output area and target parameters of the ultrasonic signal output by the ultrasonic generator based on the input instruction, and control the ultrasonic generator 200 to output an ultrasonic signal to the target output area according to the current frequency and the target parameters; wherein, the target parameters include at least one of the target duty cycle, target frequency and target intensity of the ultrasonic signal.

[0040] Among them, the transducer chip 210 is an electronic component capable of realizing energy conversion. The ultrasonic generator 200 can output ultrasonic signals through the transducer chip 210. At least one transducer chip 210 is provided in the output area A1 of the ultrasonic generator. A cell culture plate can be arranged on the transducer chip 210 of each output area A1, so that the ultrasonic signals output by the transducer chip 210 stimulate the cells on the cell culture plate, thereby conducting cell experiments. Among them, one well area of the cell culture plate corresponds to one output area A1, and cells can be arranged in each well area of the cell culture plate. For example, the ultrasonic generator includes 6 output areas A1, which can be adapted to a 6-well bidirectional stress cell culture plate. For example, four transducer chips 210 are provided in the output area A1 of the sound generator, so that each position in the well area of the cell culture plate can be stimulated by ultrasonic signals, which is beneficial to improving the accuracy and reliability of cell experiments. The ultrasonic controller 100 can be connected to the transducer chip 210, so as to output a pulse width modulation signal to the transducer chip 210. The transducer chip 210 is excited by an electrical signal (pulse width modulation signal), and the material of the transducer chip 210 will undergo periodic mechanical deformation. This mechanical vibration propagates in the medium to form ultrasonic signals. Therefore, by outputting a pulse width modulation signal to the transducer chip 210, the ultrasonic controller 100 can control whether each transducer chip 210 outputs ultrasonic signals, and control the parameters of the ultrasonic signals output by each transducer chip 210 (including at least one of duty cycle, frequency and intensity).

[0041] Specifically, by setting the ultrasonic generator 200 to include at least two different frequencies of transducer chips 210, and during the same ultrasonic generation process, the frequencies of the transducer chips 210 corresponding to all output areas A1 are the same. Then, during the cell experiment, different frequencies of transducer chips 210 can be replaced according to needs, so as to adapt to different experimental requirements, improve the flexibility and application range of the ultrasonic generator, facilitate repeated implementation, and improve the reliability and accuracy of the experiment. Among them, for example, different types of transducer chips 210 can include a transducer chip with an operating frequency of 1 MHz, a transducer chip with an operating frequency of 1.5 MHz, and a transducer chip with an operating frequency of 2 MHz, or can also include transducer chips with other frequencies, which can be specifically determined according to needs, and this embodiment does not make any limitations.

[0042] It should be noted that when replacing the transducer chips 210 with different frequencies, it can be replaced manually, or different frequencies of transducer chips 210 can be connected through switches. By controlling the conduction or cut-off of the switches corresponding to different frequencies of transducer chips 210, it can be controlled whether the corresponding transducer chips 210 are connected to the ultrasonic controller 100, that is, the transducer chips 210 connected to the ultrasonic generator 200 are selected to realize automatic replacement of the transducer chips 210.

[0043] Moreover, the ultrasonic controller 100 can obtain the current frequency of the transducer 210, control the target pulse width modulation signal output to the transducer 210 according to the current frequency, so that the frequency of the target pulse width modulation signal output to the transducer 210 matches the current frequency of the transducer 210, enabling the transducer 210 to work in an optimal state, achieving efficient energy conversion, optimizing the signal transmission path, ensuring efficient transmission of ultrasonic energy to the experimental sample, and improving the experimental effect. In this way, intelligent identification and automatic adjustment of the frequency are realized.

[0044] In addition, the input instruction may include a target parameter and a target output area. The ultrasonic controller 100 can receive the input instruction, determine the target output area and the target parameters of the ultrasonic signal output by the ultrasonic generator based on the input instruction, 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 the target parameters, so as to control whether each output area A1 outputs an ultrasonic signal, and control at least one of the intensity, duty cycle, and frequency of the ultrasonic signal output by each output area A1. In this way, the requirements of different experimental conditions can be met, and the flexibility and accuracy of the experiment can be improved. Each output area A1 can be independently adjusted according to different experimental requirements to ensure the reliability and repeatability of the experimental results.

[0045] In the technical solution of this embodiment, by setting that the ultrasonic generator includes at least two transducers with different frequencies, and during the same ultrasonic generation process, the frequencies of the transducers corresponding to all output areas are the same, then during the cell experiment, different transducers with different frequencies can be replaced according to requirements, so as to adapt to different experimental requirements, improve the flexibility and application range of the ultrasonic generator, facilitate repeatability, and improve the reliability and accuracy of the experiment. The ultrasonic controller can obtain the current frequency of the transducer, control the pulse width modulation signal output to the transducer according to the current frequency, so that the frequency of the pulse width modulation signal output to the transducer matches the current frequency of the transducer, enabling the transducer to work in an optimal state and achieving efficient energy conversion. In addition, the ultrasonic controller can receive the input instruction, determine the target output area and the target parameters of the ultrasonic signal output by the ultrasonic generator based on the input instruction, and control the ultrasonic generator to output the ultrasonic signal to the target output area according to the current frequency and the target parameters, so as to control whether each output area outputs an ultrasonic signal, and control at least one of the intensity, duty cycle, and frequency of the ultrasonic signal output by each output area. In this way, the requirements of different experimental conditions can be met, and the flexibility and accuracy of the experiment can be improved. Each output area can be independently adjusted according to different experimental requirements to ensure the reliability and repeatability of the experimental results.

[0046] Optionally, referring to Figure 1 , the ultrasonic generator 200 further includes a flexible circuit board 201;

[0047] The transducer chip 210 is located on the flexible circuit board 201. The transducer chip 210 is electrically connected to the flexible circuit board 201, and the flexible circuit board 201 is connected to the ultrasonic controller 100 through a pluggable interface 202.

[0048] Specifically, the transducer chip 210 can be soldered to the flexible circuit board 201, so that the transducer chip 210 is electrically connected to the flexible circuit board 201. And the flexible circuit board 201 is connected to the ultrasonic controller 100 through the pluggable interface 202. When replacing the transducer chip 210 with different frequencies, the replacement can be directly realized by plugging and unplugging through the pluggable interface 202, which is convenient for replacing the transducer chip 210 with different frequencies. The flexible circuit board 201 and the pluggable interface 202 can be connected through a connecting wire or other circuits, which is not limited here.

[0049] Based on the above technical solution, Figure 2 is a schematic diagram of the circuit structure of an ultrasonic generator provided by an embodiment of the present invention. Optionally, referring to Figure 2 , the ultrasonic controller 100 includes a first processing chip 110 and a plurality of processing modules 120; the processing modules 120 correspond to the output areas A1 one by one;

[0050] The first processing chip 110 is respectively connected to each processing module 120. The first processing chip 110 is used to obtain the current frequency of the transducer chip 210, receive an input instruction, and send the current frequency and the input instruction to the processing module 120. The processing module 120 is used to determine a target output area and target parameters of the ultrasonic signal output by the ultrasonic generator based on the input instruction, and output a target pulse width modulation signal to the transducer chip 210 in the corresponding output area according to the current frequency and the target parameters.

[0051] Among them, the first processing chip 110 is the main control chip. The first processing chip 110 may include a single-chip microcomputer chip, an ARM chip (such as a chip of the STM32 series), a digital signal processing (DSP) chip, or a field programmable gate array (FPGA).

[0052] Specifically, the processing module 120 can determine the target output area and the target parameters of the ultrasonic signal output by the ultrasonic generator based on the input instruction, and output a target pulse width modulation signal to the transducer chip 210 in the corresponding output area according to the current frequency and the target parameters. The processing modules 120 correspond to the output areas A1 one by one, so that the ultrasonic signals corresponding to each output area A1 can be controlled separately, 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.

[0053] The processing module 120 corresponds one-to-one with the output area A1, that is, one processing module 120 corresponds to one output channel, so that it can be connected to each output area A1 through an independent channel, and the parameters of the ultrasonic signal in each output area A1 can be independently adjusted.

[0054] Based on the above technical solution, optionally, referring to Figure 2 , the processing module 120 includes a second processing chip 121, an amplification control unit 122, and an amplifier 123;

[0055] The second processing chip 121 is connected to the first processing chip 110, and the second processing chip 121 is connected to the amplification control unit 122; the second processing chip 121 is used to adjust the amplification factor output by the amplification control unit 122 according to the target parameters;

[0056] The amplifier 123 is respectively connected to the second processing chip 121 and the amplification control unit 122; the second processing chip 121 is used to output an initial pulse width modulation signal to the amplifier 123 according to the current frequency and target parameters, and the amplifier is used 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 a target pulse width modulation signal to the transducer 210 in the corresponding output area A1.

[0057] Among them, the second processing chip 121 is a slave chip, and the second processing chip 121 may include a single-chip microcomputer chip, an ARM chip (such as a chip in the STM32 series), a digital signal processing (DSP) chip, or a field programmable gate array (FPGA). The input end of the amplification control unit 122 can be connected to the input power supply and convert the input power supply, such as step-down or step-up. The voltage output by the amplification control unit 122 is transmitted to the amplifier 123 as the amplification factor, and the amplification factor of the amplifier 123 can be controlled. 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 amplifying the voltage amplitude or power of the initial pulse width modulation signal.

[0058] Specifically, the second processing chip 121 can output an initial pulse width modulation signal according to the current frequency and target parameters. For example, it can determine the frequency and / or duty cycle of the output initial pulse width modulation signal according to the current frequency and target parameters, and 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 pulse width modulation signal according to the amplification factor output by the amplification control unit 122. As a result, the frequency of the target pulse width modulation signal finally output by the ultrasonic controller 100 matches the current frequency of the transducer 210, the intensity of the target pulse width modulation signal conforms to the target intensity in the target parameters, and the duty cycle of the target pulse width modulation signal conforms to the target duty cycle in the target parameters, thereby improving the efficiency of the ultrasonic signal output by the transducer 210 and the output ultrasonic signal meeting the requirements. In this way, the parameters of the ultrasonic signal output by the transducer 210 according to the target pulse width modulation chip are the target parameters, so that the ultrasonic signal output by the transducer 210 can be controlled according to the requirements.

[0059] In some embodiments, the input instruction may include a target output area and target parameters corresponding to the target output area. The target parameters include a target intensity (or target voltage amplitude) and a target duty cycle. According to the target parameters in the input instruction, the duty cycle and intensity of the target pulse width modulation signal can be adjusted, so as to realize the adjustment of the duty cycle and intensity of the ultrasonic signal. According to the current frequency of the transducer 210, the frequency of the target pulse width modulation signal can be adjusted so that the frequency of the target pulse width modulation signal matches the current frequency of the transducer 210.

[0060] Optionally, the first processing chip 110 and the second processing chip 121 can transmit signals through SPI (Serial Peripheral Interface) communication.

[0061] The second processing chip 121 and the amplification control unit 122 can transmit signals through I2C communication.

[0062] Optionally, the amplification control unit 122 includes a buck-boost chip 1221;

[0063] 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.

[0064] Specifically, the buck-boost chip 1221 is a controllable buck-boost chip. Then, the second processing chip 121 can control the output voltage of the buck-boost chip 1221, that is, control the amplification factor output by the buck-boost chip 1221. Thus, the amplification factor output by the buck-boost chip 1221 can be controlled according to the target parameter, and further, the target pulse width modulation signal output by the ultrasonic controller 100 can be controlled, and further, the ultrasonic signal output by the transducer 210 can be controlled.

[0065] Based on the above technical solutions, optionally, referring to Figure 2 , the ultrasonic controller 100 further includes a display screen 130;

[0066] The display screen 130 is connected to the first processing chip 110. The display screen 130 is configured to receive an input instruction and transmit the input instruction to the first processing chip 110. The first processing chip 110 is further configured to obtain 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 the actual parameters to the display screen 130. The display screen 130 is further configured to display the output status and the actual parameters.

[0067] Among them, the display screen 130 can be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen, which is not limited in this embodiment. The output status of each output area A1 may include whether the transducer 210 in the output area A1 normally outputs an ultrasonic signal, that is, whether the output area A1 normally outputs an ultrasonic signal. The display screen 130 can be connected to the first processing chip 110 in a serial connection manner.

[0068] Specifically, by setting the display screen 130 to display the output status of each output area 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. Moreover, it enables the experimenter to immediately adjust the experimental parameters according to the output status of each output area A1 and the actual parameters of the ultrasonic signal generated by the transducer 210, ensuring the accuracy and reliability of the experiment. For example, an input instruction can be input through the display screen 130. The display screen 130 transmits the input instruction to the first processing chip 110, and the first processing chip 110 transmits the input instruction to the processing module 120, so that the processing module determines the target output area and the target parameters of the ultrasonic signal according to the input instruction, and further realizes the control of each output area A1.

[0069] Table 1 is a schematic table of the display content of the display screen. The display content of the display screen 130 is shown in Table 1. When the display screen 130 is actually displayed, it can be displayed in the form of an interface or in the form of a table. This embodiment does not make any limitations.

[0072] For example, the ultrasonic generator includes six output areas, namely the first output area, the second output area, the third output area, the fourth output area, the fifth output area, and the sixth output area. As shown in Table 1, CH1 represents the first channel, which is the output channel of the transducer 210 in the first output area; CH2 represents the second channel, which is the output channel of the transducer 210 in the second output area; CH3 represents the third channel, which is the output channel of the transducer 210 in the third output area; CH4 represents the fourth channel, which is the output channel of the transducer 210 in the fourth output area; CH5 represents the fifth channel, which is the output channel of the transducer 210 in the fifth output area; CH6 represents the sixth channel, which is the output channel of the transducer 210 in the sixth output area. The voltage is the actual voltage value of the ultrasonic signal, the intensity is the actual intensity of the ultrasonic signal, and the duty cycle is the actual duty cycle of the ultrasonic signal.

[0073] In the display screen 130, the output status of each channel (i.e., each output area A1) can also be displayed in the form of an indicator light, and the duration of the output ultrasonic signal (i.e., the running time) can also be displayed, so as to time the experiment. The display screen 130 can also display the current time. The display screen 130 can also display 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.

[0074] Exemplarily, a plurality of duty cycle adjustment bars and a plurality of voltage amplitude adjustment bars can be set in the display screen 130.

[0081] The first processing chip 110 is connected to the storage module 150. The first processing chip 110 is used to transmit the current frequency, target parameters, and the time corresponding to the target parameters to the storage module 150.

[0082] Specifically, the storage module 150 includes a memory. The first processing chip 110 is used to transmit the current frequency, target parameters, and the time corresponding to the target parameters to the storage module 150, so that the storage module 150 can record the detailed information of each operation, which is convenient for review and management. Thus, the specific parameters and time of each operation can be automatically recorded, which is convenient for subsequent data analysis and experimental result verification.

[0083] Optionally, referring to Figure 2 or Figure 3 , the ultrasonic generator 200 further includes a matching module 220;

[0084] The matching module 220 is connected between the pluggable interface 202 and the flexible circuit board 201.

[0085] Specifically, the matching module 220 includes an impedance matching circuit that can perform impedance matching. The impedance matching circuit can include capacitors and inductors, and an appropriate type of matching circuit can be selected according to factors such as the operating frequency and power requirements of the transducer 210. By setting the matching module 220, the transducer 210 can obtain the maximum power from the control signal output by the ultrasonic controller 100, improving the circuit efficiency.

[0086] Optionally, referring to Figure 3 , the ultrasonic generator 200 further includes a detection module 230;

[0087] The detection module 230 is connected to the ultrasonic controller 100 and is used to detect the current frequency of the transducer 210 and transmit the current frequency to the ultrasonic controller 100.

[0088] Among them, the detection module 230 can be connected to the ultrasonic controller 100 through a pluggable interface 202.

[0089] Specifically, the detection module 230 can include a detection resistor. For example, each transducer 210 corresponds to a detection resistor. By obtaining the resistance value of the detection resistor, the current frequency of the transducer 210 can be determined according to the resistance value of the detection resistor, thereby knowing the frequency operating range of the transducer 210. Transmitting the current frequency to the ultrasonic controller 100, the ultrasonic controller 100 outputs a control signal according to the current frequency, so that the frequency of the control signal (target pulse width modulation signal) output by the ultrasonic controller 100 matches the current frequency of the transducer 210, thereby ensuring the best experimental effect.

[0090] Exemplarily, the operation process of the ultrasonic generator can include the following steps:

[0091] Step a1: Start the ultrasonic generator. Specifically, connect the power supply and start the ultrasonic generator, and the ultrasonic controller 100 and the ultrasonic generator 200 start self-checking.

[0092] Step a2: Select the target output area and target parameters. Specifically, according to the experimental requirements, input an input command through the display screen 130, and the input command includes the target input area and target parameters.

[0093] 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.

[0094] Step a4: Real-time monitoring. Specifically, during the experiment, the status of each output area A1 and the current parameters of the corresponding ultrasonic signal can be monitored in real time through the display screen 130 to ensure the transparency and controllability of the experimental process.

[0095] 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.

[0096] Step a6: Complete the experiment. Specifically, after the experiment ends, the target parameters and time of the ultrasonic signal for each operation can be obtained from the storage module 150, and the experimental data of the cells can be obtained, and the experimental data is saved and the ultrasonic generator is turned off.

[0097] During the experiment, steps a2 - a5 can be repeatedly executed to complete experiments with various different parameters.

[0100] Specifically, the ultrasonic controller 100 can obtain the current frequency of the transducer 210, control the pulse width modulation signal output to the transducer 210 according to the current frequency, so that the frequency of the pulse width modulation signal output to the transducer 210 matches the current frequency of the transducer 210, enabling the transducer 210 to work in an optimal state and realizing efficient energy conversion.

[0101] S102: The ultrasonic controller receives an input instruction and determines the target output area and the target parameters of the ultrasonic signal output by the ultrasonic generator based on the input instruction.

[0102] Specifically, the input instruction may include the target parameters and the target output area. The ultrasonic controller 100 can receive the input instruction and determine the target output area and the target parameters of the ultrasonic signal output by the ultrasonic generator based on the input instruction.

[0104] Specifically, the ultrasonic controller 100 controls the ultrasonic generator 200 to output an ultrasonic signal with target parameters to the target output area according to the current frequency and the target parameters, so that it is possible to control whether each output area A1 outputs an ultrasonic signal, and to control at least one of the intensity, duty cycle, and frequency of the ultrasonic signal output by each output area A1. In this way, the requirements of different experimental conditions can be met, and the flexibility and precision of the experiment can be improved. Each output area A1 can be independently adjusted according to different experimental requirements to ensure the reliability and repeatability of the experimental results.
