[0002] Alzheimer's disease is a chronic and progressive neurodegenerative disease, mainly manifested by the gradual decline of functions such as memory, thinking, and behavior. As the disease progresses, the quality of life of patients will be severely affected, and it will also bring a heavy burden to families and society. Therefore, the early recognition and intervention of Alzheimer's disease are particularly important. Electroencephalogram, as a non-invasive neuroelectrophysiological detection technology, can record the electrical activities of brain neurons and provide an important means for the cognitive assessment and acquisition of Alzheimer's disease.

[0003] After retrieval, for example, the utility model patent with the Chinese patent publication number CN220193037U discloses an electroencephalogram monitor. Through the settings of a servo motor, a transmission rod, and a gear, it is connected to an external power supply. When the servo motor is turned on, the rotation of the transmission rod drives the rotation of the gear, thereby driving the slide rod to move up and down, which is beneficial to adjusting the height of the device and facilitating meeting the use height of the electroencephalogram detector body by the user and facilitating the user to monitor patients.

[0004] However, the electroencephalogram examination instrument body in this utility model patent is directly exposed. Since the examination instrument is a precision instrument, the exposed examination instrument may be damaged due to external collisions and other factors, reducing its service life. Therefore, an electroencephalogram acquisition device applied to the cognitive assessment of Alzheimer's disease patients is proposed. Summary of the Invention

Specific implementation manner

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-5 , a brain electrical signal acquisition device applied to the cognitive assessment of Alzheimer's disease patients in this embodiment, includes an EEG host 1, a display 2, and a protective shell 4. The left side of the EEG host 1 is electrically connected with an electrode wire 3, and a support mechanism 5 is arranged at the bottom of the EEG host 1 and the display 2.

[0018] Set appropriate parameters on the EEG host 1 and start the recording function. At this time, the EEG host 1 will collect weak electrical signals on the patient's scalp through the electrode wire 3. During the collection process, a series of cognitive tasks, such as memory tests, attention tests, language understanding, etc., are presented to the patient. These tasks are designed to stimulate the brain to generate specific electrical activity patterns, thereby reflecting the patient's cognitive ability. The collected EEG data will be displayed on the display 2 in real time, and these data will be used for subsequent cognitive assessment analysis. The above is the process of the device realizing the cognitive assessment and collection of Alzheimer's disease patients.

[0019] The wire winding column 12 includes a column body 101 and a pressing ring 102. By setting the wire winding column 12, it is convenient to wind the electrode wire 3 and the wire of the display 2 around the column body 101, and the pressing ring 102 is sleeved on the column body 101 to prevent the wire from loosening.

[0020] The support mechanism 5 includes a bottom plate 501 and a top plate 502. A bottom plate 501 and a top plate 502 are arranged inside the protective shell 4. A connecting seat 503 is arranged on the top of the bottom plate 501. Two shock absorbers 504 are hinged on the top of the connecting seat 503. The tops of the two shock absorbers 504 are both hinged to the top plate 502. Two springs 505 are fixedly installed between the bottom plate 501 and the top plate 502.

[0021] By setting up the protective shell 4, it is possible to prevent the EEG host 1 and the display 2 from being exposed when not in use, and to prevent adverse effects on precision instruments caused by factors such as collisions. By setting up the support mechanism 5, the top plate 502 plays a role in supporting the EEG host 1 and the display 2. Under the action of the connecting seat 503, the shock absorber 504, the spring 505 and the guide block 506, the shock absorption function is achieved, and the vibration generated when the protective shell 4 moves is reduced, further protecting the EEG host 1 and the display 2.

[0022] The positioning mechanism 6 includes a positioning frame 601, a box body 602, a lead screw 603, a slide bar 604 and a lifting block 605. The lifting block 605 is threadedly connected to the lead screw 603 and slidably connected to the slide bar 604. When the lead screw 603 is rotated, the positioning frame 601 can be driven to move up and down, so as to achieve the effect of fixing and releasing the fixation of the EEG host 1 and the display 2. According to the different requirements of the use scenario, the EEG host 1 and the display 2 can be fixed in the protective shell 4 or taken out and placed in other positions, improving the flexibility of use.

[0023] By setting up the electric push rod 7, the EEG host 1 and the display 2 can be moved up or retracted from the open end of the protective shell 4, which facilitates the operation and ensures the protection function when not in use. The power supply provides power to the electric push rod 7.

[0024] During implementation, the following steps are carried out for operation: 1) First, place the EEG host 1 and the display 2 on the top plate 502 and fix them through the positioning mechanism 6, so that the two positioning frames 601 are respectively pressed on the EEG host 1 and the display 2. When not in use, both the EEG host 1 and the display 2 are stored inside the protective shell 4 2) Then, move the device to the use position through the hand push rod and the moving wheels at the bottom of the protective shell 4; 3) When in use, start the two electric push rods 7 to drive the support mechanism 5 to move upward, so that the EEG host 1 and the display 2 are moved out of the protective shell 4; 4) Finally, after use, retract the EEG host 1 and the display 2 back into the protective shell 4.

[0025] In summary, for the EEG acquisition device applied to the cognitive assessment of Alzheimer's patients, by setting the protective shell 4, the support mechanism 5 and the positioning mechanism 6, when not in use, the EEG mainframe 1 and the display 2 can be stored inside the protective shell 4, avoiding damage caused by external collisions and other factors, thereby extending the service life of the device. By setting the support mechanism 5, when moving the protective shell 4, the vibration can be effectively reduced, further protecting the EEG mainframe 1 and the display 2 from damage. At the same time, through the positioning mechanism 6, the EEG mainframe 1 and the display 2 can be fixed inside the protective shell 4 or taken out and placed in other positions according to the different requirements of the usage scenario, improving the flexibility of use.
