Description

Technical Field

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

[0002] Neurorehabilitation hand training is a very important field of rehabilitation, which aims to restore the flexibility, coordination and strength of the hands of people whose hand functions are impaired due to neurological problems (such as stroke, cerebral palsy, multiple sclerosis, etc.). Common neurorehabilitation hand training methods include simple movements such as clenching a fist, extending fingers, and bending wrists, which can help improve the flexibility and strength of hand muscles.

[0003] Active training and passive training are both important methods in neurorehabilitation hand training. The difference between them lies mainly in the degree of patient participation in the training process. Active training emphasizes that patients actively participate in hand movements and complete various movements through their own efforts. For example, exercises such as clenching fists, stretching fingers, and grasping objects. This training method can better stimulate the patient's neuromuscular adaptability and improve the autonomous control ability of the hand. Passive training uses external forces (such as therapists or equipment) to drive the hand to move. For example, using a hand rehabilitation robot or performing a hand massage. Passive training can help relieve tension in the hand muscles, increase blood circulation in the hand, and also provide a certain amount of exercise stimulation for the hand.

[0004] Chinese utility model patent CN214806505U discloses a pneumatic rehabilitation assistive glove, which drives each finger cuff of the glove to bend and straighten through a pneumatic flexible drive belt, thereby realizing the training of the patient's finger joints. The pneumatic rehabilitation assistive glove can only be used for passive hand training of the patient's neurological rehabilitation, and cannot be used for active hand training of the patient's neurological rehabilitation, nor can it be used for wrist flexion training of the patient's neurological rehabilitation.

[0030] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a hand training device for neurological rehabilitation, including a hand support plate 100 , a support plate 200 , a plurality of groups of finger training components 300 and a finger training driver 400 .

[0031] A palm area 110 and a finger area 120 are respectively provided on the upper side of the hand support plate 100 .

[0032] The support plate 200 is disposed above the palm area 110 of the hand support plate 100 , and a palm positioning space is formed between the support plate 200 and the hand support plate 100 .

[0033] Each set of finger training components 300 includes an elastic sheet 310 and a finger sleeve 320 .

[0034] Reference Figure 2 In order to facilitate fixing the elastic sheet 310 on the hand support plate 100 , a plurality of insertion holes 130 are provided at the front end of the palm area 110 of the hand support plate 100 , and the rear ends of the elastic sheets 310 are plugged into the insertion holes 130 one by one.

[0035] The finger training driver 400 includes two side plates 410 relatively fixed on the support plate 200, a rotating shaft 420 rotatably installed between the two side plates 410, a motor 430 for driving the rotating shaft 420 to rotate, a plurality of winding wheels 440 spaced apart and corresponding to each finger sleeve 320, and a traction line 450 correspondingly connected between each winding wheel 440 and the finger sleeve 320. In order to facilitate fixing the traction line 450 on the upper side of the finger sleeve 320, a connecting piece 321 is provided on the upper side of the finger sleeve 320, and a connecting hole is provided on the connecting piece 321, and one end of the traction line 450 passes through the connecting hole and is sleeved on the connecting piece 321.

[0036] In order to guide the traction wire 450 connected to the finger sleeve 320 of each finger training component 300 into each winding wheel 440 from the front, a plurality of wire guides 500 are provided above the hand support plate 100 near the front side of each winding wheel 440. The wire guides 500 are provided with wire holes 510. Each traction wire 450 passes through the wire holes 510 on each wire guide 500 one by one. Specifically, the middle of the wire hole 510 is a small hole just for the traction wire 450 to pass through, and the two ends of the wire hole 510 are respectively tapered openings that gradually expand from the small hole in the middle to the two ends. In order to facilitate the fixing of the wire guide 500 to the front side of the winding wheel 440, a crossbeam 520 is fixed between the two side plates 410 and located at the front side of the winding wheel 440, and each wire guide 500 is fixed to the crossbeam 520.

When the patient's nerve rehabilitation is performed on passive finger training, the motor 430 drives the rotating shaft 420 to rotate to drive each winding wheel 440 to reel in and release each traction line 450. When reeling in, the traction line 450 pulls each elastic sheet 310 to bend upward, thereby driving the patient's fingers to bend (such as Figure 3 As shown in the figure, when the line is released, each elastic sheet 310 straightens under the action of its own elastic force, thereby driving the patient's fingers to straighten. In this way, by controlling the retraction and release of the traction line 450, the patient's fingers can be driven to bend and extend, realizing passive training of the hand fingers. When the patient's nerve rehabilitation fingers are actively trained, the patient can actively bend and extend the fingers, and the elastic sheet 310 can provide resistance for the bending and extension of the patient's fingers, meeting the requirements of active training of the patient's nerve rehabilitation hand fingers. In summary, the present application can be used not only for passive training of the hands of patients for nerve rehabilitation, but also for active training of the hands of patients for nerve rehabilitation, with diverse functions.

The upper end of each guide column 140 is threadedly connected with a locking nut 142 locked on the upper side of the support plate 200.

[0039] In this embodiment, the support plate 200 can not only support and install the finger training driver 400, but also press the patient's palm against the hand support plate 100 during the training process. When fixing the patient's palm, the support plate 200 can be raised by rotating each locking nut 142, so that it is convenient to insert the patient's palm between the hand support plate 100 and the support plate 200. After the patient's palm is inserted between the hand support plate 100 and the support plate 200, the support plate 200 can be lowered by rotating each locking nut 142, so that the support plate 200 is pressed on the patient's palm, thereby fixing the patient's palm.

[0040] In order to improve the comfort of the hand support plate 100 and the support plate 200 in clamping and fixing the patient's palm, soft pads 210 are provided on the upper side of the palm area 110 of the hand support plate 100 and the lower side of the support plate 200.

[0041] In some embodiments, referring to Figure 1 and Figure 2 The device also includes a base 600, an arm support plate 700 and a wrist training driver. The arm support plate 700 is fixed on the base 600. The arm support plate 700 is provided with an arm fixer 710. The arm fixer 710 can be a strap.
