Description

Technical Field

[0001] This utility model relates to the field of hand rehabilitation training technology, and specifically to a hand rehabilitation training device. Background Technology

[0002] Currently, hand rehabilitation training devices generally use pneumatically driven devices to assist patients in grasping exercises. Traditional devices mostly use a single air pump with an airbag structure, which suffers from poor air pressure stability and slow movement response, and cannot achieve independent control of multiple fingers. In addition, conventional airbag structures rely on the natural rebound of the elastomer during contraction and reset, making it impossible to achieve precise control of the opening angle. For stroke patients with finger spasticity, they lack finger separation training functions, making it difficult to achieve selective finger rehabilitation treatment. Therefore, there is an urgent need for a hand rehabilitation training device with finger separation control capabilities, stable and adjustable air pressure, and active contraction function.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figures 1 to 10 As shown, the structure of this utility model is as follows: a hand rehabilitation training device, including a housing 1, a control panel 3 and a drive assembly 4 are disposed inside the housing 1; the drive assembly 4 includes a first air pump 401, a second air pump 402 and a third air pump 403 connected in series, the air inlet end of the first air pump 401 is provided with a pressure relief port 404; a first solenoid valve 5, including three interfaces A, B and C, wherein interface A 501 is connected to the air outlet of the first air pump 401, and interface B 502 is connected to the air inlet of the third air pump 403; a diversion assembly 6, through the first Pipe 7 is connected to interface C 503. At least two second solenoid valves 8 are provided on the diversion assembly 6. The training glove 9 has an execution unit 10 on its back corresponding to each finger. The execution unit 10 is connected to the output end of the second solenoid valve 8 via the second pipe 11. The first air pump 401, second air pump 402, third air pump 403, first solenoid valve 5, and second solenoid valve 8 are all electrically connected to the control panel 3. During gripping training, the control panel 3 activates the first air pump 401 and switches the first solenoid valve 5 to connect interface A 501 to interface C 503. 03 Connected, B interface 502 closed. Since the first air pump 401, the second air pump 402, and the third air pump 403 are connected in series, and the second air pump 402 and the third air pump 403 are currently closed, the air intake of the first air pump 401 cannot draw air, forcing the first air pump 401 to draw air in through the pressure relief port 404. The air then enters the diversion assembly 6, and through the selective opening of the second solenoid valve 8, the airflow is delivered to the execution unit 10 on the back of the training glove 9 corresponding to the fingers, driving single or multiple fingers to bend; when performing finger... During the opening training, the first solenoid valve 5 switches to connect interfaces B 502 and C 503, while closing interface A 501. The first air pump 401 stops working, and the second air pump 402 and the third air pump 403 start. By selectively opening the second solenoid valve 8, air is drawn out of the execution unit 10 corresponding to the finger. The air flows through the diversion component 6 and is then discharged from the pressure relief port 404, thereby driving the finger to extend and reset. By precisely controlling the on / off state of the solenoid valve and the combined operation of the air pumps, independent or coordinated rehabilitation training modes for each finger can be flexibly realized.

[0030] like Figure 7 , Figure 8As shown, the execution unit 10 includes a silicone base 1001 fixedly mounted on the back of the training glove 9. Buckles 1002 are spaced apart on the silicone base 1001, and bellows 1003 are snapped onto the buckles 1002. The bellows 1003 communicates with the second pipe 11. Specifically, the bellows 1003 is snapped onto the spaced buckles 1002 on the silicone base 1001 and communicates with the second pipe 11. When inflated, the bellows 1003 expands longitudinally under air pressure, extending through the buckles 1002 onto the silicone base 1001. 01 Apply segmented traction force to cause the back of the training glove 9 to bend towards the palm, thereby pulling the corresponding fingers to complete the grasping action; when degassing, the second air pump 402 and the third air pump 403 work together to draw air into the bellows 1003 to make it contract, and apply segmented pulling force to the silicone base 1001 through the buckle 1002 to cause the fingers to extend naturally. By controlling the airflow path through the second solenoid valve 8, the inflation and deflation state of one or more bellows 1003 can be precisely adjusted to achieve flexion and extension training of single finger independently or in coordination.

[0031] like Figure 8 As shown, the bellows 1003 includes alternating telescopic joints 1004 and fixed joints 1005. The fixed joints 1005 are engaged with the snap fasteners 1002. The telescopic joints 1004 are located between two adjacent snap fasteners 1002. Specifically, when inflated, the telescopic joints 1004 expand and elongate axially under the action of air pressure, while the fixed joints 1005 remain relatively fixed due to the constraint of the snap fasteners 1002. The linear deformation of the telescopic joints 1004 generates segmented thrust on the silicone base 1001 through each snap fastener 1002, thereby causing the training glove 9 to bend. When deflating, the air pressure is released, causing the telescopic joints 1004 to retract. Through the tension generated by each snap fastener 1002 on the silicone base 1001, combined with the elastic restoring characteristics of the silicone base 1001, the fingers are pushed to extend naturally.

[0032] The housing 1 contains a battery 2 that is electrically connected to the control panel 3. Specifically, the battery 2 is integrated inside the housing 1, which reduces the size of the device through a compact layout and provides power to the entire device through its electrical connection with the control panel 3.

[0033] like Figure 2 As shown, a speaker 15 is provided inside the housing 1. The speaker 15 is electrically connected to the control panel 3. The speaker 15 provides sound feedback when the button is pressed, which, combined with the action prompt sound, forms a dual guidance of touch and hearing, improving the accuracy and safety of rehabilitation training.

[0034] like Figure 4 , Figure 6As shown, the flow splitting assembly 6 includes a flow splitter body 601. The flow splitter body 601 has a flow splitting chamber 602 for gas distribution inside. One end of the flow splitting chamber 602 is provided with a first connector 603 that communicates with the first pipe 7. The flow splitter body 601 has at least two flow splitting channels 604 that communicate with the flow splitting chamber 602. Specifically, after air enters the flow splitting chamber 602 through the first connector 603 via the first pipe 7, it diffuses evenly inside the flow splitting chamber 602 and is output to the corresponding second solenoid valves 8 through the flow splitting channels 604 respectively. Each flow splitting channel 604 independently controls the gas through the corresponding second solenoid valve 8, and can flexibly switch between single-channel or multi-channel synchronous gas supply states.

[0035] like Figure 4 As shown, one end of the second solenoid valve 8 is connected to the diversion channel 604, and the other end is provided with a fixing block 605. The fixing block 605 is provided with a second connector 606 that communicates with the second solenoid valve 8. Bolts 607 that are threadedly connected to the diverter body 601 are passed through both sides of the fixing block 605. Specifically, the fixing block 605 is threadedly locked to the diverter body 601 by the bolts 607 on both sides, clamping and fixing the second solenoid valve 8 between the diverter body 601 and the fixing block 605. The second solenoid valve 8 achieves a stable connection and air passage through the fixing block 605 and the diverter body 601, ensuring the air passage is sealed. When the second solenoid valve 8 is energized and opened, the gas in the diversion chamber 602 enters the second solenoid valve 8 through the diversion channel 604, and is delivered to the execution unit 10 of the training glove 9 through the second connector 606 and the second pipe 11.

[0036] like Figure 9 As shown, a mirror glove 12 is provided on one side of the training glove 9. Each finger of the mirror glove 12 has a corresponding magnetron 13 on its back. Each magnetron 13 is used to control the opening and closing of the corresponding second solenoid valve 8. Specifically, the magnetron 13 is connected to the control panel 3 wirelessly or via wire. When the patient moves a finger of the mirror glove 12, the corresponding magnetron 13 on its back generates a magnetic signal according to the change in the finger's bending angle, triggering the control panel 3 to adjust the opening and closing state of the corresponding second solenoid valve 8. For example, when a single finger of the mirror glove 12 is bent, the first air pump 401 is activated, and the air is released through the corresponding magnetron. Signal 13 activates the second solenoid valve 8 at the same position as the training glove 9, allowing the airflow from the diversion component 6 to enter the execution unit 10 through the second pipe 11, driving the finger to bend accordingly. Conversely, when the finger of the mirror glove 12 extends, the first solenoid valve 5 switches to the air extraction circuit, and the magnetron 13 signals the second solenoid valve 8 to open. This, in conjunction with the second air pump 402 and the third air pump 403, draws air out of the execution unit 10, causing the finger of the training glove 9 to return to its original position. Through the real-time linkage between the magnetron 13 and the solenoid valve, precise feedback of the mirror movement to the air path of the training glove 9 is achieved, enhancing the synchronicity and coordination of rehabilitation training.

[0037] likeFigure 10 As shown, a heat dissipation hole 14 is provided on the housing 1 at the position corresponding to the drive component 4, for dissipating heat from the drive component 4.

[0038] In practical use, the first air pump 401, the second air pump 402, and the third air pump 403 are connected in series and work in conjunction with the first solenoid valve 5 and the second solenoid valve 8 to achieve precise control of finger grasping and extension: During grasping training, the control panel 3 starts the first air pump 401, switches the first solenoid valve 5 to connect interface A 501 and interface C 503, and closes interface B 502. At this time, the second air pump 402 and the third air pump 403 are in the off state, and the first air pump 401 draws in air from the pressure relief port 404. The airflow enters the diversion assembly 6 through the first pipe 7. The air is selectively opened by the second solenoid valve 8 and delivered via the second pipe 11 to the corresponding pneumatic actuator 10 on the back of the training glove 9, driving single or multiple finger flexion. During finger opening training, the first solenoid valve 5 switches to connect interface B 502 and interface C 503, and closes interface A 501. The first air pump 401 stops, and the second air pump 402 and the third air pump 403 start. The air in the actuator 10 is drawn back by the control of the second solenoid valve 8, and the airflow is discharged from the pressure relief port 404 through the diversion component 6 and the first pipe 7, causing the fingers to extend and return to their original position. The control panel 3 can dynamically adjust the start / stop of the air pumps and the on / off state of the solenoid valve interfaces to achieve independent or coordinated rehabilitation training modes for each finger.

[0039] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
