Description

Technical Field

[0001] The present invention relates to the field of brain detection technology, and in particular to a test auxiliary system and method for brain diseases. Background Art

[0002] Through magnetic resonance imaging (MRI) examinations, doctors can detect some patients with brain problems. These patients usually need to continue with tests such as brain waves to accurately assess their condition.

[0003] However, these patients may have cognitive impairment, low cooperation or poor comprehension due to brain diseases, which may cause them to be unable to follow the doctor's instructions during the EEG test, resulting in certain difficulties in the test. In particular, the open-closed eyes test in the EEG test is designed to help doctors make relevant diagnoses based on the changes in the patient's brain waves when their eyes are open and closed. Since patients with brain problems may not be able to accurately execute the "open eyes" or "close eyes" instructions, the test may not accurately reflect the changes in brain waves as expected, thus affecting the accuracy of the diagnosis.

[0004] Therefore, there is a need for a test auxiliary system and method for brain diseases that can effectively solve the problem of non-cooperation of patients with brain diseases in an open-closed eyes test and improve the accuracy of the test. Summary of the invention

[0005] One of the purposes of the present invention is to provide a test auxiliary system for brain diseases, which can effectively solve the problem of non-cooperation of patients with brain diseases in open-closed eyes tests and improve the accuracy of the test.

[0006] In order to solve the above technical problems, this application provides the following technical solutions:

[0007] Test assistance systems for brain disorders, including:

[0008] An automatic control module, used for inputting an open-closed eye test rule, converting the open-closed eye test rule into a light cycle control rule, and generating a light on or light off instruction according to the light cycle control rule;

[0009] A light source control module is used to control the switch state of the connected light source according to the instruction of turning on or off the light, so as to simulate the state of opening and closing eyes;

[0010] The brightness monitoring module is used to monitor the ambient brightness and determine whether the ambient brightness is consistent with the target brightness of the current lighting state. If not, a prompt message is generated;

[0011] The data synchronization module is used to obtain environmental brightness data and light source switch status data. It is also used to obtain the electroencephalogram from the brain wave testing equipment, mark the changes of environmental brightness data and light source switch status data over time on the horizontal axis of the electroencephalogram, and generate a visual report of the open-closed eyes test.

[0012] Furthermore, it also includes a manual adjustment module for obtaining a user input for turning on or off the light or adjusting the brightness; the light source control module is also used to adjust the light source brightness according to the brightness adjustment instruction.

[0013] Furthermore, it also includes a status monitoring module, which is used to obtain the patient's test image data in real time, and then identify the patient's eye status based on the test image data; it is also used to identify that the patient's eyes are closed when the test is in progress and the light source is on, and generate a reminder message.

[0014] Furthermore, the state monitoring module is also used to analyze whether the patient has uncomfortable behavior according to the test image data during the test, and the uncomfortable behavior refers to the patient opening eyes, closing eyes, and then opening eyes within a preset time when the light source is turned on;

[0015] If there is any inappropriate behavior, a brightness reduction instruction is generated; the light source control module is also used to control the connected intelligent light source to reduce the brightness according to the brightness reduction instruction.

[0016] Furthermore, the state monitoring module is also used to analyze the average blinking interval of the patient according to the patient's eye state before the test, and record the time of each blink;

[0017] During the test, if there is any uncomfortable behavior, it is judged whether it is a normal blink based on the time interval between the uncomfortable behavior and the last blink, as well as the average blink interval. If it is a normal blink, it is judged as a false alarm. If it is an abnormal blink, it is confirmed as uncomfortable behavior and a brightness reduction instruction is generated.

[0018] Furthermore, the state monitoring module is also used to send a start test instruction to the automatic control module after completing the analysis of the patient's average blink interval and after the patient blinks again.

[0019] A second object of the present invention is to provide a test assistance method for brain diseases, using the above system, including the following contents:

[0020] S0. Build a completely dark test environment for shading to ensure that there is no external light interference during the test, install switches and light sources with adjustable brightness; attach detection electrodes to the head of the patient being tested and connect the EEG test equipment;

[0021] S1. Rules for inputting open-closed eyes test;

[0022] S2, converting the open-closed eyes test rule to the light cycle control rule;

[0023] S3, according to the converted light cycle control rule, controlling the light source to turn on and off the light to simulate the state of opening and closing eyes;

[0024] S4. Continuously monitor the ambient brightness, and if the ambient brightness is found to not meet the target brightness requirement, generate a prompt message;

[0025] S5. Obtain environmental brightness data, light source switch status data, and electroencephalogram data from the brain wave testing equipment, mark the changes of environmental brightness data and light source switch status data over time on the horizontal axis of the electroencephalogram, and generate a visual report of the open-closed eyes test.

[0026] This solution uses an automatic control module to automatically control the switch of the light source within a preset time interval, thereby simulating the "eyes open" and "eyes closed" states, avoiding the trouble of patients' inability to cooperate and improving the operability and accuracy of the test. Through the brightness monitoring module, the brightness changes in the test environment can be monitored in real time to ensure that the ambient brightness meets the current light source status requirements. Through the data synchronization module, the light source switch status, ambient brightness, and EEG data in the brain wave testing equipment can be obtained in real time, and these data can be time-synchronized and marked to generate a visual report. It provides doctors with a comprehensive and intuitive record of the open-closed eyes test process, helping doctors to more accurately analyze patients' brain wave changes and evaluate patients' brain functions.

[0027] In summary, this solution successfully solves the problem of non-cooperation of patients with brain diseases in the open-closed eyes test through automated control, real-time monitoring and data synchronization, improves the accuracy of the test, and provides strong technical support for the early detection and diagnosis of brain diseases. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 A flow chart of embodiment 1 of a test assistance method for brain disorders;

[0029] Figure 2 The figure is a logic block diagram of the second embodiment of the test assistance system for brain diseases. DETAILED DESCRIPTION

[0030] The following is further described in detail through specific implementation methods:

[0031] Embodiment 1

[0032] The open-close eyes test of this embodiment is also called visual response, which is a normal response in the process of brain development. When the visual pathway is intact, there is no visual stimulation when the eyes are closed, and the visual cortex of the occipital region of a normal person shows an inherent α rhythm; when the eyes are open, the input of visual stimulation enhances the activity of the occipital cortex, and the α rhythm is blocked, replaced by a desynchronized low-amplitude fast wave.

[0033] The test auxiliary system for brain diseases of this embodiment includes an automatic control module, a light source control module, a brightness monitoring module, and a data synchronization module.

[0034] The automatic control module is used to input the open-closed eye test rule, convert the open-closed eye test rule into the light cycle control rule, and generate the light on or light off instruction according to the light cycle control rule. In this embodiment, the open-closed eye test rule is: the patient opens his eyes for 5 seconds every 10 seconds, and repeats this 3 times. The converted light cycle control rule is: turn off the light for 10 seconds, then turn on the light for 5 seconds, and repeat this 3 times.

[0035] The light source control module is used to control the on / off state of the connected intelligent light source (such as LED light) according to the instructions to turn on or off the light to simulate the open and closed eyes state; it also supports multi-level brightness adjustment to adapt to the light sensitivity of different patients.

[0036] The brightness monitoring module is used to monitor the ambient brightness and determine whether the ambient brightness is consistent with the target brightness of the current lighting state. If not, a prompt message is generated; for example, when the lights are off, the ambient brightness must be lower than 0.0001lux.

[0037] The data synchronization module is used to obtain environmental brightness data and light source switch status data. It is also used to obtain an electroencephalogram from an electroencephalogram testing device, mark the changes in environmental brightness data and light source switch status data over time on the horizontal axis of the electroencephalogram, and generate a visual report of the open-closed eyes test.

[0038] like Figure 1 As shown, based on the above system, this embodiment also provides a test auxiliary method for brain diseases, including the following contents:

[0039] S0. Build a completely dark test environment for shading to ensure that there is no external light interference during the test, and install a switch and an intelligent light source with adjustable brightness. In this embodiment, the test environment is also soundproofed to control environmental noise and further reduce interference with brain wave signals. Attach detection electrodes to the head of the patient being tested and connect the brain wave test equipment.

[0040] S1. Enter the rules for the open-closed eyes test and define the time interval and state transition of each trial.

[0041] S2. Convert the open-closed eye test rule to a light cycle control rule; specifically, the "open eyes" and "closed eyes" states in the rule will correspond to the "light on" and "light off" states. In this embodiment, every 10 seconds, the light source will perform a cycle of turning off the light for 10 seconds and turning on the light for 5 seconds in sequence according to the rule.

[0042] S3. Using the light source control module, according to the converted light cycle control rules, the light source is controlled to turn on and off to simulate the state of opening and closing eyes. When the patient "opens his eyes", the light source is turned on; when the patient "closes his eyes", the light source is turned off.

[0043] S4. The brightness monitoring module continuously monitors the ambient brightness to ensure that it meets the current lighting status. For example, when the light source is turned off, the ambient brightness should be lower than 0.0001lux to ensure that the patient has no additional visual stimulation when simulating the closed-eye state. If the ambient brightness is not in line with the target brightness requirement, a prompt message is generated to remind the operator to make adjustments.

[0044] S5. The data synchronization module obtains the ambient brightness data, the light source switch status data, and the EEG data from the EEG test equipment, and synchronizes the changes of these data over time: the changes of the ambient brightness data and the light source switch status data over time are marked on the horizontal axis of the EEG, and a visual report of the open-closed eyes test is generated. This report will provide doctors with a complete record of the open-closed eyes test, helping doctors to evaluate the patient's brain function and possible symptoms based on the changes in EEG during the test.

[0045] The traditional open-closed eye test relies on the patient's conscious execution of the "open eyes" and "closed eyes" instructions, but because patients with brain diseases may have cognitive impairments or insufficient comprehension, they cannot accurately execute these instructions, resulting in inaccurate test results. Through the automatic control module of this system, the light source can be automatically controlled to switch on and off within a preset time interval, thereby simulating the "open eyes" and "closed eyes" states, avoiding the trouble of patients' inability to cooperate and improving the operability and accuracy of the test.

[0046] In addition, the brightness monitoring module can monitor the brightness changes in the test environment in real time to ensure that the ambient brightness meets the current light source status requirements. For example, when the lights are off, the ambient brightness needs to be kept below a certain threshold to simulate a non-visual stimulation environment when the eyes are closed. If the ambient brightness is detected to be inconsistent with the target requirements, the system will automatically generate a prompt message to remind the operator to make adjustments, thereby ensuring the standardization and consistency of the test environment and further improving the reliability of the test results.

[0047] Through the data synchronization module, the switch status of the light source, the ambient brightness, and the EEG data in the EEG test equipment can be obtained in real time, and these data can be time-synchronized and marked to generate a visual report. It provides doctors with a comprehensive and intuitive record of the open-closed eyes test process, helping them to more accurately analyze the patient's EEG changes and evaluate the patient's brain function.

[0048] In summary, this solution successfully solves the problem of non-cooperation of patients with brain diseases in the open-closed eyes test through automated control, real-time monitoring and data synchronization, improves the accuracy of the test, and provides strong technical support for the early detection and diagnosis of brain diseases.

[0049] Embodiment 2

[0050] like Figure 2 As shown, the difference between this embodiment and the first embodiment is that it also includes:

[0051] The manual adjustment module is used to obtain the user input of the light on, light off or brightness adjustment instruction.

[0052] The status monitoring module is used to obtain the patient's test image data in real time, and then identify the patient's eye status based on the test image data; it is also used to identify that the patient's eyes are closed when the test is in progress and the light source is on, and generate a reminder message.

[0053] In this solution, the manual adjustment module allows the operator to adjust the switch and brightness of the light source in real time according to actual needs, providing a more personalized adjustment space for individual differences in patients, especially for patients with strong light sensitivity or who require special lighting environments. The state monitoring module can accurately determine whether the patient has eyes open or closed. If the system detects that the patient is still in the eyes-closed state when the light source is turned on, it can generate a reminder message in time to remind the operator to intervene or adjust the patient appropriately, avoiding inaccurate test results due to the patient's failure to open his eyes correctly, and ensuring the reliability of the test process.

[0054] Embodiment 3

[0055] The difference between this embodiment and the second embodiment is that in this embodiment, the state monitoring module is also used to analyze whether the patient has uncomfortable behavior according to the test image data during the test, and the uncomfortable behavior refers to the patient opening eyes, closing eyes, and then opening eyes within a preset time when the light source is turned on; the preset time is 0.2-0.5 seconds;

[0056] If there is inappropriate behavior, a brightness reduction instruction is generated; the light source control module is also used to control the connected intelligent light source to reduce the brightness according to the brightness reduction instruction. In this embodiment, the brightness is reduced by 10%.

[0057] In this solution, the status monitoring module can analyze the patient's test image data in real time and identify whether the patient shows uncomfortable behavior, such as when the light source is turned on, the patient opens, closes, and then opens his eyes again in a short period of time. This behavior is usually caused by the light source being too strong or the stimulation being too great, resulting in the patient's uncomfortable reaction. By accurately detecting this uncomfortable behavior, a response is made in the first place, a brightness reduction instruction is generated, and the brightness of the light source is adjusted, thereby alleviating the patient's discomfort.

[0058] Embodiment 4

[0059] The difference between this embodiment and the third embodiment is that in this embodiment, the state monitoring module is also used to analyze the average blinking interval of the patient according to the patient's eye state before the test, and record the time of each blink.

[0060] During the test, if there is an uncomfortable behavior, it is also determined whether it is a normal blink based on the time interval between the uncomfortable behavior and the last blink and the average blink interval. If it is a normal blink, it is determined to be a false alarm. If it is an abnormal blink, it is confirmed to be an uncomfortable behavior and a brightness reduction instruction is generated. In this embodiment, the time interval between the uncomfortable behavior and the last blink is close to the average blink interval, and it is determined to be a normal blink, for example, the difference does not exceed 2 seconds.

[0061] During the testing process of this solution, if the system detects uncomfortable behavior, it will not only analyze whether there is an open-close-open behavior based on the eye state, but also make further judgments based on the patient's blink interval. If the behavior is close to the time interval of the last blink and is consistent with the patient's average blink interval, the system will judge it as a normal blink response, thereby avoiding false alarms and ensuring that only true abnormalities are identified as uncomfortable behavior.

[0062] Embodiment 5

[0063] The difference between this embodiment and the fourth embodiment is that in this embodiment, the state monitoring module is also used to send a start test instruction to the automatic control module after the patient blinks again after completing the analysis of the patient's average blink interval time.

[0064] In this solution, the state monitoring module recognizes the patient's new blinking behavior and triggers the automatic control module to start the open-closed eyes test, so that the patient is less likely to blink during the initial test process, and baseline data is obtained to help doctors make more accurate diagnoses.
