Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices for finger rehabilitation training, in particular to a wearable finger rehabilitation training device. Background Art

[0002] The wearable finger rehabilitation training device is a device that combines rehabilitation medical theory and robotic technology. It is designed to help patients with hand trauma or hemiplegia gradually restore finger movement function. This device usually uses pneumatic muscle drive and can assist patients in completing finger multi-joint compound movement function training. It is simple to operate. After adjusting the patient's training parameters, the patient can wear rehabilitation gloves to perform a variety of rehabilitation training modes, such as passive activities, active games, assisted training, two-hand mirror training, etc. The wearable finger rehabilitation training device is suitable for the elderly, young and middle-aged people and children with movement disorders in their hands, especially those with limited hand movement, muscle atrophy, movement disorders and hand sensory disorders caused by nerve or muscle problems. By cooperating with rehabilitation therapists to conduct training in picking up objects, pouring water, brushing teeth, eating, etc., the patient's daily living ability can be effectively improved. In addition, this device can also be used for rehabilitation training at home or in the community anytime and anywhere, saving time and effort and reducing the workload of medical staff.

[0003] A Chinese patent discloses a finger rehabilitation training device (authorization announcement number CN118236247A), which includes a back-of-hand attachment seat, a finger attachment seat, a first flexible driving unit and a second flexible driving unit; one end of the finger attachment seat is hinged to the back-of-hand attachment seat, including a plurality of rigid knuckle fixing seats hinged in sequence; the body length direction of the first flexible driving unit is parallel to the body length direction of the finger attachment seat, and is respectively connected to each rigid knuckle fixing seat.

[0004] The above patent adopts a design that combines an airbag and a glove. Through the action of air pressure, the airbag can squeeze the glove, thereby achieving the bending and straightening of the fingers and achieving an effective rehabilitation training effect. However, since the palm size of each patient is different, this may cause the palm and the glove to not fit tightly enough, thereby affecting the squeezing effect of the airbag on the glove. This lack of fit may reduce the effect of the patient's finger training. In addition, the existing training intensity is controlled by an air pump, but under the same air pressure, the intensity of hand training is different for patients with palms of different sizes. Therefore, it is difficult for medical staff to adjust the appropriate training intensity for patients by simply adjusting the air pump gear. For this reason, we propose a wearable finger rehabilitation training device. Summary of the invention

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1 to 5 In an embodiment of the present invention, a wearable finger rehabilitation training device includes a driving component 1, the driving component 1 includes a glove 101, and a plurality of adjustment components 2 are fixedly connected to the glove 101;

[0038] The adjustment component 2 includes a plurality of flexible slides 201 fixedly connected to the glove 101, a sliding frame 202 is slidably connected to the flexible slide 201, a gear cylinder 203 is rotatably connected inside the sliding frame 202, and the gear cylinder 203 is meshed with the flexible slide 201, a rotating disk 204 is rotatably connected inside the gear cylinder 203, two friction disks 207 are slidably connected inside the gear cylinder 203, and the two friction disks 207 are respectively located on the left and right sides of the rotating disk 204, a thrust spring 205 is fixedly connected between the friction disk 207 and the rotating disk 204, both left and right ends of the gear cylinder 203 are rotatably connected to push rods 206, and the push rods 206 are fixedly connected to the friction disk 207, and the two push rods 206 are opposite to each other. The ends are fixedly connected with a disc 208, the sliding frame 202 is fixedly connected with a hook component 3, the glove 101 is fixedly connected with a pneumatic component 4 and a detection component 5. In the initial state, the friction disc 207 is pushed by the thrust spring 205, and the friction disc 207 fully contacts the inner wall of the gear cylinder 203. At this time, the gear cylinder 203 cannot rotate under the friction force of the friction disc 207. At this time, the adjustment component 2 is in a locked state. When adjustment is needed, the disc 208 needs to be pressed by hand first, so that the disc 208 drives the friction disc 207 to move toward the inside of the gear cylinder 203 through the push rod 206. At this time, the gear cylinder 203 is released from the limit, and the push rod 206 can also open the hook component 3 when moving.

[0039] The driving assembly 1 also includes a plurality of fixed blocks 102 and movable blocks 103 fixedly connected to the glove 101, a first airbag 104 is connected between the fixed block 102 and the movable block 103, a finger sleeve 105 is provided on one side of the movable block 103, a top block 106 is fixedly connected to the finger sleeve 105, a second airbag 107 is connected between the top block 106 and the movable block 103, when gas passes through the fixed block 102 to the first airbag 104 and the second airbag 107, the first airbag 104 and the second airbag 107 expand and bend, thereby being able to drive the patient's fingers to bend.

[0040] The hook assembly 3 includes two rotating plates 301 fixedly connected to the sliding frame 202, a hinge rod 302 is rotatably connected between the two rotating plates 301, a sliding rod 303 is fixedly connected to the front and rear side walls of the push rod 206, and the sliding rod 303 is slidably connected to the hinge rod 302, and a ring block 304 is fixedly connected to the upper ends of the two hinge rods 302, and a plurality of evenly distributed two-way hooks 305 are fixedly connected to the lower side wall of the second airbag 107. In the initial state, the ring block 304 can hook the plurality of two-way hooks 305, so that when the second airbag 107 is inflated, the ring block 304 connects the plurality of two-way hooks 305, thereby causing the second airbag 107 to bend. This state is as shown in FIG. Figure 6As shown, this bending phenomenon can drive the patient's fingers to bend, thereby achieving the purpose of rehabilitation training. When adjusting the position of the sliding frame 202, it is necessary to press the disc 208 first, and the disc 208 drives the push rod 206 to move. During the movement of the push rod 206, the hinge rod 302 is driven to rotate through the sliding rod 303, thereby disengaging the ring block 304 from the multiple two-way hooks 305. At this time, the sliding frame 202 is moved to the joint position of the finger, so that when the second airbag 107 is inflated next time, the bending position can correspond to the joint of the finger, thereby improving the training effect and comfort of the training.

[0041] The pneumatic assembly 4 includes a pneumatic cylinder 401 fixedly connected to the glove 101, the pneumatic cylinder 401 is connected to a moving cylinder 402, a square block 403 is slidably connected inside the moving cylinder 402, a screw rod 404 is rotatably connected inside the moving cylinder 402, and the screw rod 404 is threadedly connected to the square block 403, a motor 405 is fixedly connected to the moving cylinder 402, and the output end of the motor 405 is fixedly connected to the screw rod 404, and a piston 406 is slidably connected inside the pneumatic cylinder 401. The piston 406 is fixedly connected to the square block 403, and an air pipe 407 is connected to the air pressure cylinder 401, and the air pipe 407 is connected to multiple fixed blocks 102. When gas needs to be filled, the motor 405 needs to be started, so that the motor 405 drives the square block 403 to move through the screw 404, and then the square block 403 drives the piston 406 to move, so as to realize the transmission of gas. When the second airbag 107 and the first airbag 104 need to restore their deformation, it is only necessary to reverse the motor 405.

[0042] Example 2: Please refer to Figures 5 to 8Based on Example 1, the detection component 5 includes a connecting tube 501 fixedly connected to the sliding frame 202, the lower end of the connecting tube 501 is connected to an elastic tube 502, and the elastic tube 502 is filled with transmission fluid. The end of the elastic tube 502 away from the connecting tube 501 is fixedly connected to a Velcro 503, and the Velcro 503 is wrapped around the side wall of the sliding frame 202, and a detection cylinder 504 is fixedly connected to the glove 101, and a movable plug 505 is slidably connected inside the detection cylinder 504. An air passage 506 is connected between the connecting tube 501 and the detection cylinder 504, and the end of the detection cylinder 504 away from the movable plug 505 is fixedly connected to a photoelectric sensor 507, and the second airbag 107 and the first airbag 104 expand to drive the patient's finger When bending, the two sides of the finger joint will squeeze the elastic tube 502, causing the transmission fluid inside the elastic tube 502 to flow to the inside of the detection tube 504 through the air passage 506, thereby driving the movable plug 505 to move. The greater the bending amplitude of the finger, the greater the squeezing force on the elastic tube 502, and the closer the distance of the movable plug 505 measured by the photoelectric sensor 507 will be. When the hand is in a straight state, the elastic tube 502 is no longer compressed and recovers its deformation. At this time, the movable plug 505 will also reset. The value measured by the photoelectric sensor 507 will be directly displayed on the display through the microcomputer. Medical personnel can observe this value and set the maximum range of movement of the motor 405 to adjust the appropriate training intensity.

[0043] The working principle of the present invention is:

[0044] When the present invention is used, first, the patient puts the glove 101 on the hand, and then adjusts the position of the sliding frame 202. When adjusting, the two discs 208 need to be pressed by hand, so that the disc 208 drives the friction disc 207 to move toward the inside of the gear cylinder 203 through the push rod 206. At this time, the gear cylinder 203 is released from the limit. At the same time, during the movement of the push rod 206, the hinge rod 302 is driven to rotate through the slide rod 303, thereby disengaging the collar block 304 from the multiple bidirectional hooks 305, and then the sliding frame 202 can be moved to the joint position of the finger;

[0045] Then, the motor 405 is started, and the motor 405 drives the screw rod 404 to rotate forward and reverse, so that the screw rod 404 drives the square block 403 to move back and forth, and the square block 403 drives the piston 406 to move back and forth, so that the gas inside the air cylinder 401 can be transmitted to the first airbag 104 and the second airbag 107 through the air pipe 407. When the gas passes through the fixed block 102 to the first airbag 104 and the second airbag 107, the first airbag 104 and the second airbag 107 expand and bend. When the gas is discharged from the first airbag 104 and the second airbag 107, the first airbag 104 and the second airbag 107 contract and straighten. Through this process, the patient's fingers can be driven to bend and straighten, thereby achieving the purpose of rehabilitation training;

[0046] When the patient's finger is bent, the two sides of the finger joint will squeeze the elastic tube 502, causing the transmission fluid inside the elastic tube 502 to flow to the inside of the detection tube 504 through the air passage 506, thereby driving the movable plug 505 to move. The amplitude of the finger bending will be proportional to the distance moved by the movable plug 505. When the hand is in a straight state, the elastic tube 502 is no longer compressed and recovers its deformation. At this time, the movable plug 505 will also reset. The value measured by the photoelectric sensor 507 will be directly displayed on the display through the microcomputer. Medical staff can observe this value and set the maximum range of movement of the motor 405 to adjust the appropriate training intensity.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
