Description

Technical Field

[0001] This application relates to the field of rehabilitation training equipment technology, and in particular to a hand rehabilitation training system. Background Technology

[0002] Brain-computer interface (BCI)-based active rehabilitation technology works by analyzing a patient's electroencephalogram (EEG) data to determine their motor intentions. This is then assisted by a movement device to perform active training, creating a closed-loop neurofeedback mechanism that promotes the remodeling of the patient's brain function. This technology primarily involves three hardware modules: signal acquisition, intention decoding, and motor feedback. In traditional BCI systems, users typically use a multi-channel EEG device to acquire EEG data, which is then sent to a computer for online analysis. Finally, an exoskeleton system is used to provide motor feedback.

[0003] Existing brainwave-based hand rehabilitation training devices use a brain computer acquisition device similar to a helmet, which is equipped with multiple brain electrodes to collect the patient's brainwaves. The exoskeleton robotic hand can then perform corresponding actions based on the analyzed signals. However, current brain computer acquisition devices are basically fixed structures, which are difficult to adapt to patients with different head sizes. This results in some brain electrodes not being able to fit closely to the patient's head, affecting the full collection of brainwaves, and thus causing the exoskeleton robotic hand to be unable to accurately perform the corresponding actions. Utility Model Content

[0004] The main purpose of this application is to provide a hand rehabilitation training system that aims to solve the technical problem that existing brainwave-based hand rehabilitation training instruments are difficult to adapt to patients with different head circumferences, which can easily lead to insufficient brainwave acquisition.

[0005] To achieve the above objectives, this application provides a hand rehabilitation training system, including an electroencephalogram (EEG) acquisition component and a motion execution component. The motion execution component is used to control the hand to perform corresponding actions. The EEG acquisition component includes an airbag headgear with a first air nozzle. Multiple EEG electrodes are disposed on the inner wall of the airbag headgear. The EEG electrodes are electrically connected to an EEG decoding module disposed on the airbag headgear. The EEG decoding module is electrically connected to the motion execution component.

[0006] Optionally, the inner wall of the airbag headgear is provided with a flexible connection layer, and the brain electrodes are all located on the other side of the flexible connection layer.

[0007] Optionally, the bottom of the airbag headgear is connected to two elastic bands, which are detachably connected.

[0008] Optionally, the motion execution component includes an airbag glove, which has a receiving cavity that mates with the hand and an air cavity that is independent of the receiving cavity. The air cavity surrounds the receiving cavity. The airbag glove has a second air nozzle that can communicate with the air cavity. The airbag glove has an exoskeleton manipulator. The exoskeleton manipulator is electrically connected to a controller located on the airbag glove. The controller is electrically connected to an EEG decoding module.

[0009] Optionally, the opening of the airbag glove is provided with a soft wrist sleeve, which is used to cover the wrist.

[0010] Optionally, the soft wristband is equipped with a hook.

[0011] Optionally, it also includes an inflation assembly for inflating the airbag headgear and airbag gloves.

[0012] Optionally, the inflation assembly includes an air pump connected to a first air tube, and the first air tube connected to a first air needle that mates with a first air nozzle and a second air nozzle.

[0013] Optionally, the inflation assembly includes a push-button valve connected to a second air tube, which is connected to a second air needle that mates with a first air nozzle and a second air nozzle.

[0014] Optionally, a push-button valve is provided on the airbag head cover.

[0015] The beneficial effects that this application can achieve are as follows:

[0016] This application includes an electroencephalogram (EEG) acquisition component and a motion execution component. The motion execution component controls the hand to perform corresponding movements. The EEG acquisition component includes an air-filled headgear with a first air nozzle. Multiple EEG electrodes are disposed on the inner wall of the air-filled headgear. The EEG electrodes are electrically connected to an EEG decoding module disposed on the air-filled headgear, and the EEG decoding module is electrically connected to the motion execution component. The EEG acquisition component in this application uses an air-filled headgear to be placed on the patient's head. The air-filled headgear can be inflated through the first air nozzle, and the air-filled headgear can expand to different degrees depending on the amount of inflation, thus flexibly controlling the internal space of the air-filled headgear. This allows the multiple EEG electrodes inside to fit snugly against the patient's head, making it suitable for patients with different head circumferences and ensuring secure wear. During EEG acquisition, this effectively prevents the EEG acquisition component from loosening, ensuring sufficient EEG acquisition by the EEG electrodes. Then, the EEG decoding module decodes the signals to form control signals, which accurately and effectively control the motion execution component to perform corresponding movements, ensuring the effectiveness of hand rehabilitation training for the patient.

[0029] Example

[0030] Reference Figures 1-4 This embodiment provides a hand rehabilitation training system, including an electroencephalogram (EEG) acquisition component 100 and an action execution component 200. The action execution component 200 is used to control the hand to perform corresponding actions. The EEG acquisition component 100 includes an airbag headgear 110, a first air nozzle 120 is provided on the airbag headgear 110, and a plurality of brain electrodes 130 are provided on the inner wall of the airbag headgear 110. The brain electrodes 130 (which can be connected by wires) are electrically connected to an EEG decoding module 140 provided on the airbag headgear 110. The EEG decoding module 140 is electrically connected to the action execution component 200.

[0031] In this embodiment, the EEG acquisition component 100 is fitted onto the patient's head using an airbag headgear 110. The airbag headgear 110 can be inflated through a first air nozzle 120, and the airbag headgear 110 can expand to different degrees depending on the amount of inflation. This allows for flexible control of the internal space of the airbag headgear 110, ensuring that the multiple EEG electrodes 130 inside can fit snugly against the patient's head. This makes it suitable for patients with different head circumferences and ensures secure wear. During EEG acquisition, this effectively prevents the EEG acquisition component 100 from loosening, ensuring sufficient EEG acquisition by the EEG electrodes 130. Then, the EEG decoding module 140 decodes the signals to form control signals, which can accurately and effectively control the action execution component 200 to perform corresponding actions, ensuring the effectiveness of the patient's hand rehabilitation training.

[0032] It should be noted that the layout of the multiple brain electrodes 130 and the specific structural composition of the EEG decoding module 140 are existing technologies. For example, the layout of the brain electrodes and the structural composition of the EEG decoding module can be found in the patent with patent number "CN211634174U" and patent name "A Brainwave Controlled Hand Function Rehabilitation Training System".

[0033] As an optional implementation, the inner wall of the airbag headgear 110 is provided with a flexible connection layer 150, and the brain electrodes 130 are all disposed on the other side of the flexible connection layer 150.

[0034] In this embodiment, the brain electrode 130 is mounted via a flexible connecting layer 150. The flexible connecting layer 150 can adapt to changes in the internal space of the airbag headgear 110, thereby improving the fit between the brain electrode 130 and the patient's head. Here, the flexible connecting layer 150 can be made of flexible materials such as medical-grade silicone, as long as it meets the usage requirements.

[0035] As an alternative implementation, the bottom of the airbag headgear 110 is connected to two elastic bands 160, which are detachably connected.

[0036] In this embodiment, two elastic bands 160 can be tied around the patient's chin to further improve the fixation of the airbag headgear 110. The two elastic bands 160 can be connected by Velcro or by buckle to achieve a detachable connection. Other detachable connection structures can also be used, and there should be no limitation on this.

[0037] As an optional implementation, the motion execution component 200 includes an airbag glove 210, which has a receiving cavity 211 that cooperates with the hand and an air cavity 212 that is independent of the receiving cavity 211. The air cavity 212 surrounds the receiving cavity 211. The airbag glove 210 is provided with a second air nozzle 220 that can communicate with the air cavity 212. The airbag glove 210 is provided with an exoskeleton manipulator 230. The exoskeleton manipulator 230 is electrically connected to a controller 240 provided on the airbag glove 210. The controller 240 is electrically connected to the EEG decoding module 140.

[0038] In this embodiment, the controller 240 can receive electrical signals sent by the EEG decoding module 140, and then control the exoskeleton robotic hand 230 to perform corresponding actions. The airbag glove 210 is a flexible part that can synchronously drive the patient's hand to perform corresponding actions for rehabilitation training. Here, the airbag glove 210 can be inflated into the air chamber 212 through the second air nozzle 220 to expand to different degrees, so that the receiving cavity 211 can be adapted to match the patient's hand. It has strong versatility. Therefore, the airbag glove 210 is worn on the patient's hand here, and the fit is good. Compared with the existing finger sleeve wearing structure, the airbag glove 210 is more secure and stable after wearing and is less likely to slip off. It is also more convenient and quick to wear.

[0039] It should be noted that both the controller 240 and the exoskeleton robotic hand 230 are existing technologies. For example, the control box and the structure of the exoskeleton robotic hand in patent number "CN211634174U" entitled "A Brainwave-Controlled Hand Function Rehabilitation Training System" can be referenced. The difference between the two exoskeleton robotic hands lies in their wearing structures. The aforementioned existing patent uses a finger-glove type, while this embodiment uses an airbag glove 210. Other structural forms of the exoskeleton robotic hand can also be used. For example, the corresponding structure in patent number "CN106264983B" entitled "Wearable Rehabilitation Training Exoskeleton Robotic Hand" can be referenced, simply replacing the wearing part with the airbag glove 210. There are many structural forms for the exoskeleton robotic hand 230, and this should not be limited to any particular form. The controller 240 and the EEG decoding module 140 can be connected via wires or wirelessly via a wireless communication module.

[0040] As an optional implementation, the opening of the airbag glove 210 is provided with a soft wrist sleeve 250, which is used to cover the wrist. When wearing it, the soft wrist sleeve 250 is first passed through, and then the airbag glove 210 is put on. The soft wrist sleeve 250 is deformable, and after being properly worn, it can fit snugly on the patient's wrist, thereby further improving the wearing security. The soft wrist sleeve 250 can also be made of materials such as medical-grade silicone.

[0041] As an optional implementation, the soft wrist sleeve 250 is provided with a hook 260. When not in use, the entire exoskeleton robotic hand 230 can be hung on the corresponding hanger through the hook 260 for easy retrieval.

[0042] As an optional implementation, it also includes an inflation assembly 300, which is used to inflate the airbag headgear 110 and the airbag glove 210. During inflation, the inflation assembly 300 can be used in conjunction with the first air nozzle 120 and the second air nozzle 220.

[0043] As an optional implementation, the inflation assembly 300 includes an air pump 310, which is connected to a first air tube 320. The first air tube 320 is connected to a first air needle 330 that cooperates with a first air nozzle 120 and a second air nozzle 220.

[0044] In this embodiment, inserting the first air needle 330 into the first air nozzle 120 or the second air nozzle 220 and pressing the air pump 310 inflates the airbag headgear 110 and the airbag glove 210 respectively. The air pump 310 can be handheld for easy operation. It should be noted that both the first air nozzle 120 and the second air nozzle 220 can adopt the inflation hole structure of a basketball, with a rubber pad inside. When the air needle is used to inflate, the rubber pad is pushed open by the immense pressure of the air pump. When the air needle is pulled out, the air inside the ball exerts an outward force on the rubber pad, causing it to return to a tightly closed state, thus preventing leakage. Similarly, when deflation is needed, the corresponding air needle can be inserted into the first air nozzle 120 or the second air nozzle 220.

[0045] As another alternative implementation, the inflation assembly 300 includes a press-type air valve 340, which is connected to a second air tube 350, and the second air tube 350 is connected to a second air needle 360 ​​that cooperates with the first air nozzle 120 and the second air nozzle 220.

[0046] In this embodiment, during inflation, the second air needle 360 ​​is inserted into the first air nozzle 120 or the second air nozzle 220, and then the press-type air valve 340 is pressed repeatedly to force external gas into the second air tube 350, thereby performing the corresponding inflation operation. Here, the press-type air valve 340 can adopt an ellipsoidal structure for easy operation.

[0047] As an optional implementation, the press-type air valve 340 is disposed on the airbag head cover 110, thereby forming an integrated structure to prevent the inflation component 300 from being lost and to allow for inflation as needed.

[0048] In other embodiments, the inflation assembly 300 may also employ an automatic inflation device, such as an air pump, to facilitate rapid inflation.

[0049] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
