TECHNICAL FIELD

[0001] The present application relates to the technical field of brain detection, in particular to a test auxiliary system and method for brain disorders. BACKGROUND

[0002] Through a magnetic resonance imaging (MRI) examination, a doctor can find some patients with brain problems, and these patients usually need to continue to take a brain wave test to accurately assess the condition.

[0003] However, these patients may have cognitive impairment, low cooperation or poor understanding due to brain diseases, which may cause them to be unable to follow the doctor's instructions when taking the brain wave test, resulting in certain difficulties in the test. Especially in the open-closed eye test in the brain wave test, the purpose is to help the doctor make relevant diagnosis through the change of brain waves of the patient in the open eye and closed eye state. Since patients with brain problems may not be able to accurately execute the "open eye" or "closed eye" instructions, the test may not accurately reflect the change of brain waves as expected, thereby affecting the accuracy of diagnosis.

[0004] Therefore, there is a need for a test auxiliary system and method for brain disorders that can effectively solve the possible non-cooperation of patients with brain disorders in the open-closed eye test and improve the accuracy of the test. SUMMARY

[0005] One of the purposes of the present application is to provide a test auxiliary system for brain disorders, which can effectively solve the possible non-cooperation of patients with brain disorders in the open-closed eye test and improve the accuracy of the test.

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

[0007] The test auxiliary system for brain disorders comprises:

[0008] An automatic control module is configured to input open-closed eye test rules, convert the open-closed eye test rules into light period control rules, and generate an open or off light instruction according to the light period control rules;

[0009] A light source control module is configured to control the on-off state of the access light source according to the open or off light instruction to simulate the open eye and closed eye state;

[0010] A brightness monitoring module is configured to monitor the ambient brightness, determine whether the ambient brightness is consistent with the target brightness of the current light state, and generate a prompt if the ambient brightness is not consistent with the target brightness of the current light state;

[0011] The data synchronization module is configured to acquire environmental brightness data and light source switch state data, and is further configured to acquire an electroencephalogram from the electroencephalogram testing device, mark the environmental brightness data and the light source switch state data changing over time on the abscissa of the electroencephalogram, and generate a visual report of the open-eye-closed-eye test.

[0012] Further, the system further comprises a manual adjustment module configured to acquire a user inputted light-on, light-off or brightness adjustment instruction, and the light source control module is further configured to adjust the brightness of the light source according to the brightness adjustment instruction.

[0013] Further, the system further comprises a state monitoring module configured to acquire testing image data of the patient in real time, and identify the eye state of the patient according to the testing image data, and is further configured to generate a reminding information when the eye state of the patient is identified as the closed-eye state in the open-eye-closed-eye test.

[0014] Further, the state monitoring module is further configured to analyze whether the patient has an uncomfortable behavior in the open-eye-closed-eye test according to the testing image data, and the uncomfortable behavior refers to the behavior of the patient opening the eyes, closing the eyes and opening the eyes again within a preset time when the light source is turned on.

[0015] If the uncomfortable behavior exists, a brightness reduction instruction is generated, and the light source control module is further configured to control the connected intelligent light source to reduce the brightness according to the brightness reduction instruction.

[0016] Further, the state monitoring module is further configured to analyze the average blink interval time of the patient according to the eye state of the patient before the open-eye-closed-eye test, and record the blink time each time.

[0017] In the open-eye-closed-eye test, if the uncomfortable behavior exists, it is further judged whether the uncomfortable behavior is a normal blink according to the time interval between the uncomfortable behavior and the last blink and the average blink interval time, if the uncomfortable behavior is the normal blink, it is judged as a false alarm, if the uncomfortable behavior is not the normal blink, it is confirmed as the uncomfortable behavior, and a brightness reduction instruction is generated.

[0018] Further, the state monitoring module is further configured to send a test starting instruction to the automatic control module after the average blink interval time of the patient is analyzed, and after the patient blinks again.

[0019] The second object of the present application is to provide a test assisting method for brain disorders, using the above system, comprising the following contents.

BRIEF DESCRIPTION OF DRAWINGS

[0028] Figure 1 Flowchart for Test Auxiliary Method Embodiment One for Brain Disorders;

[0029] Figure 2 Logic block diagram of Test Auxiliary System Embodiment Two for Brain Disorders. DETAILED DESCRIPTION

[0030] The following will be further described in detail through specific embodiments:

[0031] Embodiment One

[0032] The open-close eyes test of the embodiment, also known as visual response, is a normal response in the brain development process. In the case of complete visual pathway, there is no visual stimulus input when the eyes are closed, and the occipital visual cortex of normal people shows inherent alpha rhythm; when the eyes are open, the input of visual stimulus makes the occipital cortex activity enhanced, and the alpha rhythm is blocked, and is replaced by desynchronized low-amplitude fast wave.

[0033] The test auxiliary system for brain disorders of the embodiment comprises 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 for inputting the open-close eyes test rule, converting the open-close eyes test rule into a light period control rule, and generating an open or off light instruction according to the light period control rule. In the embodiment, the open-close eyes test rule is that the patient opens eyes for 5 seconds every 10 seconds, and this is repeated for 3 times. The converted light period control rule is that the light is off for 10 seconds, then the light is on for 5 seconds, and this is repeated for 3 times.

[0035] The light source control module is used for controlling the on-off state of the accessed intelligent light source (such as LED light) according to the open or off light instruction, so as to simulate the open eye and closed eye states; and supports multi-level brightness adjustment to adapt to the light sensitivity of different patients.

[0036] The brightness monitoring module is used for monitoring the ambient brightness, judging whether the ambient brightness is consistent with the target brightness of the current light state, and generating a prompt information if not consistent; for example, in the off light state, the ambient brightness needs to be lower than 0.0001 lux.

[0037] The data synchronization module is used for acquiring the ambient brightness data and the light source on-off state data, and is also used for acquiring the electroencephalogram from the brain wave test device, marking the ambient brightness data and the light source on-off state data with time changes on the horizontal coordinate of the electroencephalogram, and generating a visual report of the open-close eyes test.

[0038] As shown in Figure 1 Based on the above system, the embodiment further provides a test auxiliary method for brain disorders, comprising the following contents:

[0039] S0, a full black test environment for shading is built to ensure that there is no external light interference in the test process, and a switch and a brightness adjustable intelligent light source are installed. In the embodiment, the test environment is also provided with sound insulation to control the environmental noise and further reduce the interference on the brain wave signal. The detection electrode is pasted on the head of the patient to be tested, and the brain wave test device is connected.

[0040] S1, input the rule of the open-close eyes test, and define the time interval and state conversion of each test.

[0041] S2. Convert the open-closed eyes test rule to a light cycle control rule. Specifically, the "eyes open" and "eyes closed" states in the rule will correspond to the "lights on" and "lights off" states. In this embodiment, every 10 seconds, the light source will cycle from 10 seconds off to 5 seconds on, 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 eyes opening and closing. When the patient's eyes are "open", the light source is turned on; when the patient's eyes are "closed", the light source is turned off.

[0043] S4. The brightness monitoring module continuously monitors ambient brightness to ensure it meets the current lighting conditions. For example, when the light source is off, the ambient brightness should be below 0.0001 lux to ensure that the patient does not experience any additional visual stimulation when simulating a closed-eye state. If the monitored ambient brightness does not meet the target brightness requirement, a prompt message is generated to remind the operator to make adjustments.

[0044] S5. The data synchronization module acquires ambient brightness data, light source on / off status data, and EEG data from the EEG testing device. It synchronizes these data over time, plotting the changes in ambient brightness and light source on / off status data on the EEG's horizontal axis to generate a visual report of the eyes-open-closed test. This report provides doctors with a complete record of the eyes-open-closed test, helping them assess the patient's brain function and potential medical conditions based on EEG changes during the test.

[0045] Traditional open-closed eyes tests rely on patients consciously following commands to "open" and "close." However, patients with brain disorders may have cognitive impairments or limited comprehension, making it difficult to accurately follow these commands, resulting in inaccurate test results. This system's automatic control module automatically switches the light source on and off at preset intervals, simulating the "eyes open" and "eyes closed" states. This eliminates the problem of patients failing to cooperate and improves the test's operability and accuracy.

[0046] Furthermore, the brightness monitoring module monitors changes in the test environment's brightness in real time, ensuring it meets current light source requirements. For example, when the lights are off, the ambient brightness must remain below a certain threshold to simulate the visually neutral state of a closed-eye state. If the system detects that the ambient brightness does not meet the target, it automatically generates a prompt to alert the operator to make adjustments, ensuring a standardized and consistent test environment and further improving the reliability of test results.

[0047] Through the data synchronization module, the light source switch state, the environmental brightness and the electroencephalogram data in the brain wave testing device can be acquired in real time, and these data are time-synchronized and marked to generate a visual report. The doctor is provided with a comprehensive and intuitive open-eye-closed-eye test process record, which helps the doctor to more accurately analyze the brain wave changes of the patient and evaluate the brain function of the patient.

[0048] In summary, the present scheme successfully solves the possible non-cooperation of the patient with brain disorders in the open-eye-closed-eye test through automatic 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 disorders.

[0049] Embodiment Two

[0050] As shown in Figure 2 , the difference between the present embodiment and Embodiment One is that the present embodiment further comprises:

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

[0052] The state monitoring module is used to acquire the test image data of the patient in real time, and then identify the eye state of the patient according to the test image data; and is further used to generate a reminder information when the eye state of the patient is identified as the closed-eye state under the condition that the light source is turned on during the test.

[0053] In the present scheme, the manual adjustment module allows the operator to adjust the switch and brightness of the light source in real time according to the actual needs, and provides more personalized adjustment space for the individual differences of the patient, especially for the patient who is more sensitive to light or needs a special light environment. The state monitoring module can accurately determine whether the patient is in the open-eye or closed-eye state. If the system detects that the patient is still in the closed-eye state under the condition that the light source is turned on, it can generate a reminder information in time to remind the operator to intervene or adjust the patient appropriately, so as to avoid the inaccuracy of the test result caused by the patient not opening his eyes correctly, and ensure the reliability of the test process.

[0054] Embodiment Three

[0055] The difference between the present embodiment and Embodiment Two is that, in the present embodiment, the state monitoring module is further used to analyze whether the patient has an uncomfortable behavior during the test according to the test image data, and the uncomfortable behavior refers to the behavior of the patient opening his eyes-closing his eyes-opening his eyes again within a preset time when the light source is turned on; the preset time is 0.2-0.5 seconds.

[0056] If the uncomfortable behavior exists, a brightness reduction instruction is generated; and the light source control module is further used to control the reduction of the brightness of the connected intelligent light source according to the brightness reduction instruction. In the present embodiment, the brightness is reduced by 10%.

[0057] In this scheme, the state monitoring module can analyze the test image data of the patient in real time, identify whether the patient exhibits an uncomfortable behavior, for example, the patient exhibits the behavior of opening eyes-closing eyes-opening eyes again in a short time when the light source is turned on. This behavior is usually due to the light source being too strong or too stimulating, causing the patient to react uncomfortably. By accurately detecting this uncomfortable behavior, a response is made in the first time to generate a brightness reduction instruction to adjust the brightness of the light source, thereby relieving the discomfort of the patient.

[0058] Embodiment Four

[0059] The difference between this embodiment and Embodiment Three is that in this embodiment, the state monitoring module is further configured to analyze the average blink interval time of the patient and record the blink time of each blink according to the eye state of the patient before the test.

[0060] During the test, if the uncomfortable behavior exists, it is further determined whether it is a normal blink according to the time interval between the uncomfortable behavior and the last blink and the average blink interval time. If it is a normal blink, it is determined as a false alarm, and if it is an abnormal blink, it is confirmed as an uncomfortable behavior to generate a brightness reduction instruction. In this embodiment, the time interval between the uncomfortable behavior and the last blink is close to the average blink interval time, which is determined as a normal blink, for example, the difference is not more than 2 seconds.

[0061] In this scheme, if the system detects an uncomfortable behavior during the test, it not only analyzes whether the behavior of opening eyes-closing eyes-opening eyes again exists according to the eye state, but also further judges in combination with the blink interval time of the patient. If the behavior is close to the time interval of the last blink and is consistent with the average blink interval time of the patient, the system will judge it as a normal blink reaction, thereby avoiding false alarms and ensuring that only the real abnormal situation is identified as an uncomfortable behavior.

[0062] Embodiment Five

[0063] The difference between this embodiment and Embodiment Four is that in this embodiment, the state monitoring module is further configured to send a start test instruction to the automatic control module after completing the analysis of the average blink interval time of the patient.

[0064] In this scheme, the state monitoring module identifies the new blink behavior of the patient, triggers the automatic control module to start the open-closed eye test, so that the patient is less likely to exhibit a blink behavior in the first part of the test process, and the baseline data is obtained to help the doctor make a more accurate diagnosis.

[0065] The above is only an embodiment of the present application, the present application is not limited to this embodiment The field to which the embodiment relates, common knowledge of specific structures and characteristics in the scheme, etc. is not described in detail here The ordinary skilled person in the art knows all the ordinary technical knowledge in the field to which the present application belongs before the filing date or the priority date, can know all the prior art in the field, and has the ability to apply conventional experimental means before that date The ordinary skilled person in the art can perfect and implement the present scheme under the guidance of the present application, in combination with their own ability Some typical known structures or known methods should not be an obstacle to the implementation of the present application by the ordinary skilled person in the art It should be noted that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can also be made, which should also be considered as the protection scope of the present application, which will not affect the effect and practicality of the patent The scope of protection claimed in the present application should be subject to the content of its claims The specific implementation in the specification can be used to explain the content of the claims
