When the upper limb rehabilitation training device works, firstly, a patient needs to sit on the upper limb rehabilitation training device directly, the back of the patient leans against the backrest 2, the first driving motor 8a drives the first gear 7a to rotate, and the first gear 7a drives the first rack 701 to adjust the height of the backrest 2, so that the patient can wear the arm recovery mechanism 3 more comfortably; the sliding block 17 is driven to move on the sliding rail 16 by the extension and contraction of the fourth electric push rod 9a, so that the shoulder width is adjusted according to the self condition of the patient; after the position of the slide block 16 is adjusted according to the shoulder width of the patient, the patient puts the arm part into the arm recovery mechanism 3, fixes the upper arm in the third placing plate 13a by the first fixing strap 26d, fixes the lower arm in the fourth placing plate 12 and the fifth placing plate 11 by the second fixing strap 26c and the third fixing strap 26b, fixes the hand in the sixth placing plate 10 by the fourth fixing strap 26a, and then adjusts the distance between the second placing plate 13 and the third placing plate 13a by controlling the fourth driving motor 8d and the distance between the fourth placing plate 12 and the fifth placing plate 11 by the fifth driving motor 8c according to the self condition, so that the patient feels more comfortable when training by using the upper limb recovery training device; the arm recovery mechanism 3 can realize shoulder joint movement training, elbow joint movement training, and wrist joint movement training.
When carrying out shoulder joint activity training, second driving motor 8f drives first board 14 of placing and keeps the horizontality, second electric putter 9b and third electric putter 9c control third place board 13a and fourth place board 12 and keep straightening and then make patient's forearm also be in the state of straightening, sixth driving motor 8b control patient's hand also keeps straightening, first electric putter 9d shrink drives connecting plate 15 and slides along arc spout 1702, thereby drive patient's arm through whole arm recovery mechanism 3 and expand, the patient is done and is opened the chest motion, activity patient shoulder muscle crowd. After the training of the activity of opening the chest, first electric putter 9d stretches out and drives connecting plate 15 and slide along arc spout 1702, control arm recovery mechanism 3 stretches forward, place board 13a and fourth through second electric putter 9b and third electric putter 9c control third and place board 12 and drive the big arm and the forearm that the patient keeps straightening the state with the fourth, sixth driving motor 8b control patient hand also keeps straightening, second driving motor 8f drives first board 14 of placing and just reverses to move, just so drive patient's arm and lift up the back pendulum of lifting and whereabouts, thereby make patient's big arm swing round the shoulder. After the arm swing activity training is finished, first electric putter 9d stretches out, and control arm recovery mechanism 3 straightens forward, and third driving motor 8e drives second gear 7d and rotates, because the cooperation of second gear 7d and second place board 13 and go up transmission dogtooth 1301 drives the whole arm portion of patient and uses the forearm to rotate as the axle, reaches the effect of activity forearm root muscle crowd. When the shoulder joint movement is trained, the patient can be driven to train without exerting force by the patient, and the effects of relaxing the muscles and stimulating the blood circulation are achieved by training partial muscle groups of the shoulder and the large arm of the movable patient.
When elbow joint movement training is carried out, the second electric push rod 9b extends out and the third electric push rod 9c contracts, so as to push the fourth placing plate 12 to rotate around the hinging shafts of the first supporting arm 13a2 and the second supporting arm 1201, so that the forearm part of a patient can be driven to bend around the elbow joint, when the second electric push rod 9b extends out completely, the third electric push rod 9c continues to contract to drive the fourth placing plate 12 to rotate towards a larger angle, so as to drive the elbow of the patient to bend more, when the arm part of the patient bends to a certain degree, the third electric push rod 9c extends out, and the second electric push rod 9b contracts to push the arm of the patient to straighten, when the dead point of the second electric push rod 9b is passed, the second electric push rod 9b continues to contract to drive the forearm of the patient to straighten, so as to finish the bending and straightening of the elbow joint, so that the patient can be driven to carry out elbow joint movement training, the training is completed without exerting force by itself, and the effects of relaxing muscles and stimulating blood circulation are achieved by training partial muscle groups of the big arm and the small arm of the movable patient.
When carrying out wrist joint activity training, sixth driving motor 8b rotates, makes the sixth place board 10 and rotates round the articulated shaft, drives the patient hand and rotates round the wrist joint, because sixth driving motor 8 b's positive and negative rotation, can the inside and outside upset of hand to reach the effect of tempering forearm and wrist joint muscle crowd, can carry out the activity training of no power to whole wrist muscle through above training.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
