Technical Field

[0001] The invention relates to the technical field of rehabilitation training, and in particular to a hand function auxiliary rehabilitation training device for stroke patients. Background Art

[0002] "Stroke", also known as "cerebrovascular accident", is an acute cerebrovascular disease. It is a group of diseases caused by sudden rupture of brain blood vessels or blockage of blood vessels that prevent blood from flowing into the brain, causing brain tissue damage. It is a disorder of brain nerve function caused by cerebral hemorrhage. Stroke patients will have abnormal postures in the recovery period after the acute period. Stroke patients have problems such as wrist flexion, finger flexion, thumb adduction, etc.

[0003] Patients need to receive targeted training during the rehabilitation stage. Generally, doctors use their professional knowledge and rich experience to massage the patient's muscle groups for recovery. After the patient has passed the acute period in the hospital, most patients are discharged and go home to continue rehabilitation. Some simple training tasks need to be completed with the assistance of family members, but most family members know little about stroke and cannot adopt the correct posture during targeted training, resulting in unsatisfactory training results, and even incorrect training aggravates the condition. Therefore, it is necessary to propose a professional training device for stroke patients that is suitable for family use. To this end, we propose a hand function-assisted rehabilitation training device for stroke patients. Summary of the invention

[0025] Reference Figures 1 to 3As shown, a hand function auxiliary rehabilitation training device for stroke patients includes a fixing module 100, a training module 200, a collection module 300 and a control module 400; the training module 200 is placed on the fixing module 100, and the collection module 300 is connected to the control module 400; the collection module 300 and the control module 400 are both connected to a computer 500; the fixing module 100 includes a bottom plate 1, the surface of the bottom plate 1 is concave to form a hand-shaped groove 3 adapted to the shape of a human hand, and the hand-shaped groove 3 includes a palm groove 31 and five divergent finger grooves 32; the hand-shaped groove 3 is convenient for patients to imitate operations, and the columns 2 are mainly used for training fingers, and several fingers can be held together for finger flexion exercises, or two fingers can be placed between two columns to practice finger abduction, or two fingers can be placed beside two columns 2 to practice finger adduction; the elastic band 4 can not only fix the fingers, but also can induce the patient's fingers to extend upward and forward.

[0026] Among them, the training module 200 includes a plurality of columns 2, and the plurality of columns 2 are vertically arranged on the base plate 1; each column 2 is arranged on one side of each finger groove 32; the number of columns 2 is preferably six, and the finger groove 32 is located between two adjacent columns; the finger groove 32 is divergent, that is, simulating the state of the fingers being opened and extended outward; the training content is rich, and can provide all-round and particularly effective finger function training, ensuring the early recovery of the trainees.

[0027] An elastic band 4 for fixing the finger is provided at the fingertip position of the finger groove 32. The base plate 1, the column 2 and the elastic band 4 are made of a flexible material, and the flexible material is vulcanized rubber. The vulcanized rubber has high elasticity, heat resistance, tensile strength and insolubility in organic solvents.

[0028] The fixing module 100 also includes a top plate 5 that is mirror-symmetrical to the bottom plate 1, and the columns 2 are arranged between the bottom plate 1 and the top plate 5; each column 2 is connected to the bottom plate 1 in a detachable manner, and column grooves 6 are provided on both sides of each finger groove 32, and the columns 2 are inserted into the column grooves 6 and fixedly connected; the columns 2 can be fixed to the column grooves 6 by threaded connection or interference fit, which is convenient for assembly and storage of the present trainer.

[0029] The training device also includes a finger sleeve 7, which is mounted on each training finger of the trainee; the control module 400 includes a controller, which is connected to the finger sleeve 7; the acquisition module 300 includes an EEG collector and a plurality of electrode caps, which are connected to the EEG collector, which is connected to the computer 500; the patient wears the electrode cap 302, which is connected to the computer 500, the EEG collector 301, and the controller; the electrode cap 302 is connected to the EEG collector 301, which is connected to the computer 500; the computer 500 is connected to the controller; the EEG collector 301 collects the patient's EEG signals, and transmits them to the computer 500 for analysis, and decodes the patient's movement intention; according to the decoded movement intention, the movement instructions are divided, processed in real time and converted into control signals and the control signals are transmitted to the controller, and after the training is completed, the device stores the usage parameters.

[0030] First, the patient wears the electrode cap 302 and imagines opening and then clenching his hands, with a frequency of 1 second to complete one action combination. Then the EEG collector 301 collects the EEG signals of the rehabilitation patient through the electrode cap 302, and transmits the EEG signals to the computer 500 in real time through the transmission line. The computer 500 pre-processes, calculates features, and determines tasks for the acquired EEG signals, decodes the patient's motor imagination intention in real time, and converts the patient's motor intention into a control signal and transmits it to the controller; finally, the controller receives the control instruction in real time and controls the finger sleeve 7 to work.

[0031] The present invention is applicable to stroke patients with severe motor dysfunction, and helps patients to carry out active rehabilitation training; the EEG collector 301 collects the patient's EEG signals, determines the patient's movement intention, and the computer 500 transmits the movement instruction to the controller in real time; the real-time processing is converted into a control signal and sent to the controller, and the EEG signal is decoded in real time to obtain the patient's movement intention. The focus of the rehabilitation effect is to give movement feedback in time, enhance the patient's feedback effect, and improve the rehabilitation effect. The human body has a wealth of sensory sensors that can better sense external stimuli. Common receptors related to movement include proprioceptors, including muscles, joints and tendons, and also receptors about the skin, including various receptor cells on the skin. Among them, thermal stimulation causes nerve impulses from thermal receptors, and the corresponding receptors are different for different stimulation forms. The rehabilitation process of stroke can be defined as the surviving neurons performing the functions generated by the lost neuronal connections. The recovery of physical or cognitive functions after stroke is largely attributed to the reorganization of neurons to compensate for the lost connections. Studies have shown that tactile stimulation can increase the activation level of the sensory motor brain area. Combined with motor feedback, it can fully mobilize the nerve cells in the patient's sensory motor brain area, promote the recombination of nerve cell connections, and re-form efficient neural connection pathways, thereby replacing the motor functions lost by stroke patients.
