Description

Technical Field

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

[0002] Stroke is a disease that causes motor and language dysfunction due to damage to the central nervous system. Patients are very likely to suffer from motor dysfunction due to damage to the brain's nerve center, and movement dysfunction is the most common functional disorder caused by stroke. About half of stroke patients still have varying degrees of limb motor dysfunction, especially hand dysfunction, after entering the chronic stage, and are unable to take care of themselves, which places a heavy burden on their families and society.

[0003] At present, most of the hand function rehabilitation devices on the market belong to peripheral intervention therapy, which is mostly "passive" rehabilitation. Patients or therapists need to operate the repeated buttons on the device to achieve "passive" hand movements. Such devices cannot read the patient's intentions, which is not conducive to the active remodeling of the patient's brain nerves. Moreover, the operation interface is single and expensive, which cannot meet the personalized rehabilitation needs of patients. Compared with traditional passive rehabilitation methods, motor imagery brain-computer interface recognizes the electroencephalogram (EEG) signals generated by the patient's active motor imagery, converts the motor imagery intention into control instructions for rehabilitation peripherals, and realizes "central-peripheral-central" closed-loop rehabilitation with active brain participation. It has a good effect on rebuilding the neural connection between the patient's hand and brain, and is a potential effective rehabilitation method.

[0004] Therefore, how to design a device system that is fully functional, easy to operate, and convenient for hand function rehabilitation training is an urgent problem to be solved by technical personnel in this field.

The technical solution of the present invention designs a fully functional, easy-to-operate and convenient pneumatic control box for hand function rehabilitation training in combination with a brain-computer interface.

[0027] The signal processing device is used to receive the signal received by the brain wave sensor and control the hand control device after processing;

[0028] The hand control device comprises a glove 1, such as Figure 1 As shown, a control shell 2 is fixedly connected to the surface of the glove 1, and a bending control mechanism 3 is fixedly connected to the outer surface of the glove 1 corresponding to the fingers, and the bending control mechanism 3 can control the bending and extension of the fingers at the glove;

[0029] Specifically, the bending control mechanism 3 includes a bending plate 301, and the bending plate 301 is fixedly connected to the outer surface of the glove 1. Figure 3 As shown, a plurality of transmission rings 302 are fixedly connected to the surface of the bending plate 301, and flexible connection rings 303 are fixedly connected between the transmission rings 302. The transmission rings 302 at both ends are fixedly connected to sealing covers 304. The sealing covers 304, the transmission rings 302 and the flexible connection rings 303 constitute a closed cavity. The closed cavity is respectively connected to one end of a connecting pipe 4, and the other end of the connecting pipe 4 penetrates the side wall of the control housing 2. A pump mechanism for forming positive and negative pressures in the closed cavity is arranged inside the control housing 2. When the closed cavity is inflated, a positive pressure can be formed inside the closed cavity, which can drive the bending plate 301 to bend, thereby controlling the bending of the finger, and vacuuming can form a negative pressure inside the closed cavity, so that the bending plate 301 straightens and controls the finger to extend.

[0030] Specifically, the pump body mechanism includes an air chamber 5 disposed inside the control housing 2, such as Figure 2As shown, the air chamber 5 includes a positive pressure air chamber 501 and a negative pressure air chamber 502, the positive pressure air chamber 501 is connected to a positive pressure air pump 6, the negative pressure air chamber 502 is connected to a negative pressure air pump 7, the positive pressure air chamber 501 and the negative pressure air chamber 502 are respectively connected to the connecting pipe 4 through a pneumatic valve 8, the positive pressure air pump 6 is used to form a positive pressure in the positive pressure air chamber 501, and the negative pressure air pump 7 is used to form a negative pressure inside the negative pressure air chamber 502, the positive pressure and the negative pressure can be maintained for a long time, so when the bending control mechanism 3 is driven, the control time is short;

[0031] Specifically, the number of the pneumatic valves 8 is multiple, and the pneumatic valves 8 are grouped in pairs. The pneumatic valves 8 in the same group are respectively connected to the positive pressure air chamber 501 and the negative pressure air chamber 502 through the conduit 9. A connector 10 is connected between the pneumatic valves 8 in the same group, and the connector 10 is connected to the connecting pipe 4.
