Description

Technical Field

[0001] The present disclosure relates to the field of electroencephalogram technology, and particularly to an electroencephalogram processing device, a marking system, and a marking method based on optoelectronic signals. Background Art

[0002] Epilepsy is one of the common neurological diseases. Clinically, a specific stimulation signal is given to the patient to induce an epileptic seizure and collect electroencephalogram signals, so as to formulate a treatment plan for the patient. The common digital video electroencephalogram system is a combination of an electroencephalogram collector and a video collector, and is widely used in epilepsy. Its working principle is to start the video recording function while collecting electroencephalogram signals, establish a one-to-one correspondence between the electroencephalogram signals and video images at each moment, so that the epileptic seizure situation of the patient can be viewed while viewing the electroencephalogram data in the later stage and assist in diagnosis.

[0003] Since the electroencephalogram signals are in a state of continuous real-time collection, the collector cannot determine the time when the patient receives the event stimulus, and thus cannot perform specific and accurate marking on the electroencephalogram data. Currently, the common method is based on the video time recorded on site, and the event-related potentials of the collected electroencephalogram signals are marked manually later, but manual operation is required, there is a certain time error, and accurate marking cannot be achieved.

[0036] In order to more clearly understand the above objects, features and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0037] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0038] Figure 1 Schematic diagram of a brain electrical signal marking system based on optoelectronic signals provided by an embodiment of the present disclosure, Figure 2The figure is a schematic structural diagram of an electroencephalogram processing device provided by an embodiment of the present disclosure. In combination with Figure 1 and Figure 2 , the electroencephalogram marking system 10 includes an electroencephalogram processing device 11 and an electroencephalogram acquisition device 12. The electroencephalogram processing device 11 includes a photoelectric conversion module 13, and the photoelectric conversion module 13 is configured to convert an optical signal corresponding to the patient image information into an electrical signal and output the converted electrical signal to the electroencephalogram acquisition device 12.

[0039] Specifically, the photoelectric conversion module 13 obtains the optical signal of the patient's optical image, and then converts the optical signal corresponding to the patient image into an electrical signal. The converted electrical signal is output to the electroencephalogram acquisition device 12, so that the electrical signal converted from the optical signal corresponding to the patient image information can be obtained. The optical signal of the patient image is obtained by taking pictures or videos of the patient, which can reflect the epileptic seizure condition of the patient. Converting the optical signal of the patient image into an electrical signal can reflect the epileptic seizure condition of the patient through the voltage and current states of the electrical signal, such as the seizure time and seizure degree.

[0040] Among them, the electroencephalogram acquisition device 12 can collect the electroencephalogram information of the patient. Thus, while the electroencephalogram acquisition device 12 obtains the electrical signal converted from the optical signal corresponding to the patient image information, it can also obtain the electroencephalogram information of the corresponding patient, so as to establish a time correspondence relationship between the electroencephalogram signal of the patient and the electrical signal converted from the optical signal corresponding to the patient image information. The electrical signal contains the epileptic seizure information of the patient. Therefore, analyzing the electrical signal can obtain the epileptic seizure condition of the patient, and then perform event marking on the electroencephalogram signal according to the time nodes of the seizure time and seizure degree. And the electrical signal is converted from the optical signal corresponding to the patient image information, and the optical signal of the patient image is obtained by taking pictures or videos of the patient, that is, the electroencephalogram signal is marked with events by using the real-scene shooting information. Thus, it can be realized to view the electroencephalogram signal of the patient based on the electrical signal in the patient's seizure state, that is, mark the electroencephalogram signal of the patient with events by the electrical signal in the patient's seizure state, which is beneficial for doctors to diagnose the patient and formulate a treatment plan based on the electroencephalogram signal collected during the patient's seizure, improving the accuracy of the patient diagnosis and the accuracy of formulating the treatment plan.

[0041] The electroencephalogram (EEG) processing device based on optoelectronic signals provided by the embodiments of the present disclosure is provided with an optoelectronic conversion module. The optoelectronic conversion module is used to convert the optical signal corresponding to the patient image information into an electrical signal and output the converted electrical signal to the EEG acquisition device. Thus, the EEG processing device can convert the optical signal corresponding to the patient image information into an electrical signal and output the converted electrical signal to the EEG acquisition device. In addition, the EEG acquisition device can acquire the EEG signal of the patient, and further can synchronously display the electrical signal converted from the optical signal of the patient image information and the EEG signal of the patient. Thus, it is possible to view the EEG signal of the patient based on the electrical signal in the patient's onset state, that is, to perform event marking on the EEG signal of the patient through the electrical signal in the patient's onset state, improving the accuracy of event marking, which is beneficial for doctors to diagnose the patient and formulate a treatment plan based on the EEG signal collected during the patient's onset, improving the accuracy of diagnosing the patient and the accuracy of formulating a treatment plan.

[0042] In some embodiments, Figure 3 is a schematic structural diagram of another EEG processing device based on optoelectronic signals provided by the embodiments of the present disclosure. As Figure 3 shown, the signal output terminal OUT of the optoelectronic conversion module 13 is electrically connected to the signal input terminal A10 of the EEG acquisition device 12 through the first connection terminal A1, and the ground terminal GND of the optoelectronic conversion module 13 is electrically connected to the ground terminal GND of the EEG acquisition device 12 through the second connection terminal A2.

[0043] Specifically, the optoelectronic conversion module 13 obtains the optical signal of the patient's optical image, and then converts the optical signal corresponding to the patient image into an electrical signal, which is output through the signal output terminal OUT of the optoelectronic conversion module 13. Further, it is input into the EEG acquisition device 12 through the first connection terminal A1. Among them, the ground terminal GND of the optoelectronic conversion module 13 is electrically connected to the ground terminal GND of the EEG acquisition device 12 through the second connection terminal A2. Thus, the optoelectronic conversion module 13 and the EEG acquisition device 12 can be electrically connected through the first connection terminal A1 and the second connection terminal A2, which is beneficial for the optoelectronic conversion module 13 to transmit the electrical signal converted from the optical signal of the corresponding patient image to the EEG acquisition device 12.

[0044] In some embodiments, Figure 4 is a schematic structural diagram of an optoelectronic conversion module provided by the embodiments of the present disclosure. Combining Figure 3 and Figure 4, the photoelectric conversion module 13 includes a first power supply U1, a photoelectric conversion element 41, and a first impedance-adjustable current-limiting element 42; the first power output terminal of the first power supply U1 is electrically connected to the first terminal D1 of the photoelectric conversion element 41, the second power output terminal of the first power supply U1 is grounded, and the photoelectric conversion element 41 is used to convert an optical signal into an electrical signal; the first terminal D3 of the first impedance-adjustable current-limiting element 42 is electrically connected to the second terminal D2 of the photoelectric conversion element 41, the second terminal D4 of the first impedance-adjustable current-limiting element 42 is grounded, and the impedance-adjustable terminal B of the first impedance-adjustable current-limiting element 42 is used to output the converted electrical signal.

[0045] Specifically, the positive electrode of the first power supply U1, that is, the first output terminal of the first power supply, is electrically connected to the first terminal D1 of the photoelectric conversion element 41, the negative electrode of the first power supply U1, that is, the second output terminal of the second power supply, is grounded, and the first power supply U1 is used to supply power to the photoelectric conversion element 41. Among them, the photoelectric conversion element 41 is used to receive the optical signal of the image information of the corresponding patient and convert the optical signal into an electrical signal. The converted electrical signal is output from the second terminal D2 of the photoelectric conversion element 41 to one end D3 of the first impedance-adjustable current-limiting element 42 and output through the impedance-adjustable terminal B of the first impedance-adjustable current-limiting element 42. In addition, the other end D4 of the first impedance-adjustable current-limiting element 42 is grounded. The first impedance-adjustable current-limiting element 42 can be set as a sliding rheostat, and the resistance value of the sliding rheostat is 1-10KΩ. While realizing the output of the converted electrical signal, the circuit voltage division can be realized by adjusting its own impedance value, and then the voltage amplitude of the electrical signal corresponding to the analog signal output or the voltage amplitude of the electrical signal corresponding to the digital signal output can be adjusted to adapt to the voltage range of the signals that the electroencephalogram acquisition device 12 can receive.

[0046] It should be noted that the output electrical signal is displayed in real time in the electroencephalogram acquisition device in the form of a waveform diagram, and the amplitude of the waveform diagram can be adjusted based on the first impedance-adjustable current-limiting element 42. Whether the light source of the optical signal corresponding to the patient's image information changes and the rate of change are reflected in the waveform diagram in the form of a slope, and the intensity of the light source change is reflected in the waveform diagram in the form of an amplitude.

[0047] In some embodiments, continuing to combine Figure 3 and Figure 4 , the photoelectric conversion module 13 further includes an analog signal converter 43, a digital signal converter 44, and a sorter 45; the first terminal D5 of the analog signal converter 43 and the first terminal D6 of the digital signal converter 44 are both electrically connected to the impedance-adjustable terminal B of the first impedance-adjustable current-limiting element 42, and the sorter 45 is used to select the second terminal D7 of the analog signal converter 43 or the second terminal D8 of the digital signal converter 44 and output the converted electrical signal.

[0048] Specifically, when the sorter 45 selects to connect the analog signal converter 43 to the signal output terminal OUT, the electrical signal output from the impedance-adjustable terminal B of the first impedance-adjustable current-limiting element 42 is output as an electrical signal in the form of an analog signal by the analog signal converter 43. Further, the electrical signal in the form of an analog signal is output to the electroencephalogram acquisition device 12 through the signal output terminal OUT of the photoelectric conversion module 11.

[0049] When the sorter 45 selects to connect the digital signal converter 44 to the signal output terminal OUT, the electrical signal output from the impedance-adjustable terminal B of the first impedance-adjustable current-limiting element 42 is output as an electrical signal in the form of a digital signal by the digital signal converter 44. Further, the electrical signal in the form of a digital signal is output to the electroencephalogram acquisition device 12 through the signal output terminal OUT of the photoelectric conversion module 11.

[0050] In some embodiments, with continued reference to Figure 4 , the photoelectric conversion module 11 further includes a first indicating component 46 and a second indicating component 47; the first end D9 of the first indicating component 46 and the first end D11 of the second indicating component 47 are both electrically connected to the impedance-adjustable terminal B of the first impedance-adjustable current-limiting element 42, the second end D10 of the first indicating component 46 is electrically connected to the first end D5 of the analog signal converter 43, and the second end D12 of the second indicating component 47 is electrically connected to the first end D6 of the digital signal converter 44.

[0051] Specifically, when the sorter 45 selects to connect the analog signal converter 43 to the signal output terminal OUT, the first indicating component 46 electrically connected to the analog signal converter 43 displays, for example but not limited to, the indicator light flashing or being always on. At this time, it can visually prompt the operator that the selected signal output mode is an analog electrical signal. When the sorter 45 selects to connect the digital signal converter 44 to the signal output terminal OUT, the second indicating component 47 electrically connected to the digital signal converter 44 displays, for example but not limited to, the indicator light flashing or being always on. At this time, it can visually prompt the operator that the selected signal output mode is a digital electrical signal.

[0052] Thus, when the operator selects the signal output mode to be in the form of an analog signal or a digital signal, the corresponding indicator light displays, which is beneficial for the operator to visually obtain the signal output mode.

[0053] In some embodiments, as Figure 3 shown, the electroencephalogram processing device 10 further includes a second impedance-adjustable current-limiting element 48. The first end H1 of the second impedance-adjustable current-limiting element 48 is electrically connected to the signal output terminal OUT of the photoelectric conversion module 13, the second end H2 of the second impedance-adjustable current-limiting element 48 is electrically connected to the second connection terminal A2, and the impedance-adjustable terminal C of the second impedance-adjustable current-limiting element 48 is electrically connected to the first connection terminal A1.

[0054] Specifically, in combination with Figure 3 and Figure 4 , when the sorter 45 selects to connect the analog signal converter 43 and the signal output terminal OUT, the signal output terminal OUT of the photoelectric conversion module 13 outputs an electrical signal in the form of an analog signal. The electrical signal in the form of an analog signal is input from the first terminal H1 of the second impedance adjustable current limiting element 48, output through the impedance adjustable terminal C of the second impedance adjustable current limiting element 48, and input to the electroencephalogram acquisition device 12 through the first connection terminal A1. Similarly, when the sorter 45 selects to connect the digital signal converter 44 and the signal output terminal OUT, the signal output terminal OUT of the photoelectric conversion module outputs an electrical signal in the form of a digital signal. The electrical signal in the form of a digital signal is input from the first terminal H1 of the second impedance adjustable current limiting element 48, output through the impedance adjustable terminal C of the second impedance adjustable current limiting element 48, and input to the electroencephalogram acquisition device 12 through the first connection terminal A1.

[0055] Among them, the second impedance adjustable current limiting element 48 can be set as a sliding rheostat, and the resistance value of the sliding rheostat is 0.5 - 10 KΩ. While realizing the output of the converted electrical signal, the voltage division of the circuit can be adjusted by adjusting its own impedance value according to the display requirements of the display module in the electroencephalogram acquisition device 12, such as a display, so as to adjust the voltage amplitude of the electrical signal output to the electroencephalogram acquisition device 12, ensuring that the display module in the electroencephalogram acquisition device 12 can completely display the received electrical signal.

[0056] In some embodiments, still referring to Figure 3 , the electroencephalogram processing device further includes a current limiting element 49. The first terminal H3 of the current limiting element 49 is electrically connected to the signal output terminal OUT of the photoelectric conversion module 13, and the second terminal H4 of the current limiting element 49 is electrically connected to the first terminal H1 of the second impedance adjustable current limiting element 48.

[0057] Specifically, the photoelectric conversion module 13 obtains the optical signal of the patient's optical image, and then converts the optical signal corresponding to the patient's image into an electrical signal. The electrical signal converted by the photoelectric conversion module 13 is output from the signal output terminal OUT to the first terminal H3 of the current limiting element 49, and output to the second impedance adjustable current limiting element 48 through the second terminal H4 of the current limiting element 49. Thus, by setting the current limiting element 49, when the impedance adjustable terminal C of the second impedance adjustable current limiting element 48 is at the first terminal H1, it can avoid the short circuit caused by the connection between the signal output terminal OUT and the ground terminal.

[0058] Thus, the electroencephalogram (EEG) processing device based on optoelectronic signals provided by the embodiments of the present disclosure can be connected and compatible with existing EEG machine products through the first terminal A1 and the second terminal A2. In addition, by setting the second impedance-adjustable current-limiting element 48, the voltage amplitude of the output electrical signal can be adjusted to adapt to the waveform display range of different EEG machines. Therefore, the embodiments of the present disclosure are not limited by the model of the EEG acquisition device 12 and have universality and generality.

[0059] Based on the above embodiments, the embodiments of the present disclosure further provide an EEG marking system based on optoelectronic signals. As Figure 1 shown, the EEG marking system 10 includes any one of the EEG processing devices 11 based on optoelectronic signals provided in the above embodiments, and further includes an EEG acquisition device 12, and the EEG acquisition device 12 is communicatively connected to the EEG processing device 11. Among them, the EEG acquisition device 12 is used to acquire the EEG signals of the patient.

[0060] Exemplarily, the connection between the EEG acquisition device 12 and the EEG processing device 11 can be a wireless communication connection method or a wired communication connection method, and the embodiments of the present disclosure do not make specific limitations thereto.

[0061] The EEG marking system based on optoelectronic signals provided in the above embodiments includes the EEG processing device based on optoelectronic signals provided in the above embodiments, and has the same or similar beneficial effects, which will not be elaborated herein.

[0062] In some embodiments, Figure 5 is a schematic structural diagram of another EEG marking system based on optoelectronic signals provided by the embodiments of the present disclosure. As Figure 5 shown, the EEG acquisition device 12 includes a display module 14, and the display module 14 is used to display the converted electrical signal and the EEG signal acquired by the EEG acquisition device 12.

[0063] Thus, the electrical signal converted from the optical signal of the patient image information and the acquired EEG signal of the patient are synchronously displayed, and then the EEG signal is event-marked according to the change of the electrical signal, avoiding the manual marking work of the operator in the later stage, and thus improving the work efficiency.

[0064] Exemplarily, the display module 14 of the EEG acquisition device 12 simultaneously displays the converted electrical signal of the corresponding patient and the acquired EEG signal of the patient. When the electrical signal suddenly changes, at this moment, the EEG acquisition device 12 can automatically mark the EEG signal of the patient.

[0065] Based on the above embodiments, the embodiments of the present disclosure further provide an electroencephalogram (EEG) marking method based on optoelectronic signals, which is implemented based on any one of the EEG marking systems based on optoelectronic signals provided in the above embodiments and has the same or similar beneficial effects, which will not be elaborated here.

[0066] Figure 6 FIG. is a schematic flowchart of an EEG marking method based on optoelectronic signals provided by an embodiment of the present disclosure. As Figure 6 shown, the EEG marking method includes:

[0067] S601. Obtain an electrical signal converted from an optical signal corresponding to patient image information.

[0068] S602. Obtain the EEG signal of the patient;

[0069] S603. Perform event marking on the EEG signal according to the electrical signal.

[0070] Specifically, an electrical signal converted from an optical signal corresponding to patient image information and the EEG signal of the patient are obtained simultaneously to realize synchronous display of the electrical signal and the EEG signal. Then, event marking is performed on the EEG signal according to the waveform change of the waveform diagram, that is, the waveform change of the waveform diagram in the patient's disease state, without manual event marking, which is beneficial to improving work efficiency.

[0071] Exemplarily, the display device of the EEG acquisition device always displays the electrical signal converted from the optical signal of the patient image information and the EEG signal of the patient. When a sudden change occurs in the electrical signal, such as too high voltage, at a certain moment, for example, at time t1, it can be determined that time t1 is the time when the patient has a disease. At this time, event marking is performed on the node of the EEG signal corresponding to time t1.

[0072] Based on the same inventive concept, the embodiments of the present disclosure further provide an EEG marking device based on optoelectronic signals. Figure 7 FIG. is a schematic structural diagram of an EEG marking device based on optoelectronic signals provided by an embodiment of the present disclosure.
