Description

Technical Field

[0001] This invention relates to the field of motor training technology for cerebral palsy, specifically to a fine motor training device for children with cerebral palsy based on game interaction. Background Technology

[0002] Cerebral palsy is one of the most common physical disabilities in children, with its core manifestations being abnormal motor development and postural control disorders. Fine motor skills of the hands are the basic functions for children's daily life self-care, cognitive development, and social participation. Therefore, fine motor rehabilitation training for children with cerebral palsy has important clinical significance and social value. For example, the patent with announcement number CN209236754U discloses an interactive rehabilitation training device for children with cerebral palsy, which includes a horizontal support rod, a panel, and a flat plate. The left end of the horizontal support rod is equipped with a handle, and a storage compartment is provided below the horizontal support rod. The panel is fixed to the upper end of the movable rod, and a U-shaped groove is provided at the rear of the panel. The flat plate is installed at the lower left corner of the panel, and a hinge is connected to the left end of the flat plate. It can assist children with cerebral palsy in simple walking training. The second support column and the movable rod can extend and retract to adjust the height of the panel above the movable rod relative to the ground, so as to adapt to the standing height of children with cerebral palsy of different heights. The hands can be supported on the panel, which can reduce the weight borne by the feet of children with cerebral palsy during walking training. For example, the patent CN119185016A describes a tactile enhancement rehabilitation training system based on virtual-real interaction, which includes a hand exoskeleton module, a hand exoskeleton target detection module, a tactile feedback control module, and a virtual-real interactive rehabilitation training game module. The hand exoskeleton module includes a hand fixation unit, a power transmission unit, a Hall encoder, and a finger execution unit. The hand fixation unit is equipped with finger execution units that match each of the patient's fingers. The tactile feedback control module includes a controller and an electrical stimulation device. The virtual-real interactive rehabilitation training game module is configured with a specific control strategy. For example, the patent with publication number CN120636685A, "Multimodal Rehabilitation Training System for Children with Cerebral Palsy Based on Artificial Intelligence," includes a data acquisition and preprocessing module, a multimodal information fusion module, a personalized rehabilitation training suggestion generation module, an interaction and incentive module, a progress tracking and abnormal warning module, a doctor and parent-side APP management module, and a system control and management module. This invention, by combining the interaction and incentive module with the multimodal information fusion module in the rehabilitation training of children with cerebral palsy, can significantly improve training effectiveness and achieve accurate assessment and personalized training. Most of the existing technologies mentioned above improve the overall structure. However, existing fine motor training devices for children with cerebral palsy can only train single actions such as grasping or pinching during operation. They cannot simulate the fine operations in daily life, such as single-finger clicking or alternating pressing. Children cannot know whether their pressing pressure is up to standard or whether their actions are correct. The training effect depends on the therapist's subjective observation, which leads to certain limitations in use. Summary of the Invention

[0003] The purpose of this invention is to provide a fine motor training device for children with cerebral palsy based on game interaction, in order to solve the problems mentioned in the background art, which can only train single actions such as grasping or pinching, and cannot simulate the fine operations in daily life, such as single-finger clicking, alternating pressing, etc. The children cannot know whether their pressing pressure is up to standard or whether their actions are correct. The training effect depends on the therapist's subjective observation, thus having certain limitations in use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fine motor training device for children with cerebral palsy based on game interaction, comprising a preset base, wherein an audio-visual interactive button is nested on the inner side of the preset base, and a first return spring is fixedly connected to the lower end of the audio-visual interactive button, and the first return spring is mutually connected to the inner side of the preset base; a fixed top rod is fixedly connected to the inner side of the preset base, and the fixed top rod passes through the inner side of the audio-visual interactive button; an insulating flexible layer is provided on the inner side of the upper end of the audio-visual interactive button, and the lower end of the insulating flexible layer corresponds to the upper end of the fixed top rod; a guide bearing structure is provided on the inner side of the audio-visual interactive button, which prompts the user whether the pressing pressure is appropriate.

[0005] Furthermore, the guiding bearing structure is provided with a docking reserved part, and the docking reserved part is fixedly docked to the outside of the fixed top rod. The docking reserved part is nested and docked along the inner side of the sound and light interactive button. A limiting docking part is nested and installed on the upper outer side of the sound and light interactive button, and a second reset spring is fixedly connected to the inner side of the limiting docking part. The second reset spring and the sound and light interactive button are docked with each other.

[0006] Furthermore, the lower end of the limiting docking component is fixedly connected to a built-in guide steel wire rope component, which runs through the inner side of the sound and light interactive button, and the end of the built-in guide steel wire rope component is docked with the lower outer end of the docking reserved component.

[0007] Furthermore, the sound and light interactive buttons are evenly distributed about the center point of the preset base, and the sound and light interactive buttons form an elastic support structure along the inner side of the preset base through the first reset spring. The inner side of the sound and light interactive buttons slides nested along the fixed top rod and the outer side of the docking reserved part.

[0008] Furthermore, the fixed top rod and the docking reserved part, which are fixed in relative position, drive the limiting docking part to form a traction structure through the built-in guide steel wire rope component. The limiting docking part forms a sliding structure along the inner side of the sound and light interactive button through the second reset spring.

[0009] Furthermore, an adaptive adjustment structure is provided between the preset substrate and the sound and light interactive button, which controls the button triggering force of the sound and light interactive button. The adaptive adjustment structure is provided with a built-in vertical corrugated liquid bladder component, which is bonded to the inner side of the preset substrate. The upper end of the built-in vertical corrugated liquid bladder component corresponds to the lower end of the sound and light interactive button. A fitting and connecting piece is nested on the inner side of the lower end of the preset substrate.

[0010] Furthermore, the lower end of the fitting and docking component is connected to a threaded fitting component, and the upper end of the fitting and docking component is connected to a pre-drilled liquid bladder. The pre-drilled liquid bladder is located on the inner side of the preset base, and a supply hose is provided on the outer side of the pre-drilled liquid bladder. The supply hose passes through the inner side of the preset base and is connected to the built-in vertical corrugated liquid bladder component.

[0011] Furthermore, the threaded docking component drives the fitting docking component to form a threaded rotation structure along the inner side of the lower end of the preset substrate, and the fitting docking component applies pressure to the contacting docking reserved liquid bladder.

[0012] Furthermore, the reserved liquid bladder is supplied to the interior of the built-in vertical corrugated liquid bladder component through the supply hose, and the built-in vertical corrugated liquid bladder component expands vertically to apply pressure to the lower end of the sound and light interactive button.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This game-based interactive fine motor training device for children with cerebral palsy features a guiding support structure. This structure prompts the user to check if the pressure applied is appropriate. Users can press corresponding audio-visual interactive buttons based on their illuminated status. The pressed buttons move along the inner side of a pre-set base. When the fixed rod nested inside the button contacts the flexible insulating layer, the deformed layer, in conjunction with the fixed rod, contacts the user's finger, indicating that the pressure applied is sufficient. The user can then release the button, simulating fine motor operations in daily life, such as single-finger clicking or alternating pressing. This allows the child to determine if their pressure applied is adequate. Furthermore, as the sound and light interactive button moves downward along the outside of the fixed top rod under force, the fixed top rod and the docking reserved part, which are fixed in relative position, will drive the limiting docking part to form a traction force state through the built-in guide steel wire rope component. As the sound and light interactive button moves downward, the limiting docking part can slide inward along the inside of the sound and light interactive button, thereby correcting the patient's finger pressing method and achieving the effect of controlling and adjusting the patient's pressing action to provide standardized prompts. Furthermore, an adaptive adjustment structure is incorporated to control the trigger force of the audio-visual interactive buttons. Users can hold the threaded connector and rotate it along the inner lower end of the preset substrate, creating a threaded rotation. This causes the connector to apply pressure to the pre-drilled liquid bladder, which then supplies liquid through a supply hose to the internal vertical corrugated liquid bladder component. The vertical expansion of the internal vertical corrugated liquid bladder component applies pressure to the lower end of the audio-visual interactive buttons, increasing the subsequent pressing force required. This allows for graded adjustable button trigger force, covering needs ranging from passive assisted training for severely disabled children to active resistance training for mildly disabled children, thus improving the device's practicality.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1-8 This invention provides the following technical solution: a fine motor training device for children with cerebral palsy based on game interaction. To address the problem that training can only focus on single actions such as grasping or pinching, and cannot simulate the finer operations required in daily life, such as single-finger clicking or alternating pressing, and that children cannot know whether their pressing pressure is adequate or their movements are standardized, with training effectiveness dependent on the therapist's subjective observation, the device discloses the following: a sound-light interactive button 2 is nested inside a preset base 1, and a first return spring 3 is fixedly connected to the lower end of the sound-light interactive button 2, with the first return spring 3 engaging with the inner side of the preset base 1; a fixed top rod 5 is fixedly connected to the inner side of the preset base 1, and the fixed top rod 5 extends along the inner side of the sound-light interactive button 2; an insulating flexible layer 6 is provided on the inner side of the upper end of the sound-light interactive button 2, with the lower end of the insulating flexible layer 6 corresponding to the upper end of the fixed top rod 5; and a guide bearing structure is provided on the inner side of the sound-light interactive button 2, which prompts the user whether the pressing pressure is appropriate.

[0018] The guiding support structure is equipped with a docking pre-reserved part 7, which is fixedly docked to the outside of the fixed top rod 5. The docking pre-reserved part 7 is nested along the inner side of the sound-light interactive button 2. A limiting docking part 9 is nested on the outer side of the upper end of the sound-light interactive button 2, and a second return spring 10 is fixedly connected to the inner side of the limiting docking part 9. The second return spring 10 and the sound-light interactive button 2 are docked with each other. A built-in guide steel wire rope component 8 is fixedly connected to the lower end of the limiting docking part 9, and the built-in guide steel wire rope component 8 passes through the inner side of the sound-light interactive button 2. The end of component 8 is connected to the lower outer side of the docking pre-reserved part 7. The sound and light interactive buttons 2 are evenly distributed about the center point of the preset base 1, and the sound and light interactive buttons 2 form an elastic support structure along the inner side of the preset base 1 through the first reset spring 3. The inner side of the sound and light interactive buttons 2 slides nested with the outer side of the fixed top rod 5 and the docking pre-reserved part 7. The fixed top rod 5 and the docking pre-reserved part 7, which are fixed in relative position, drive the limiting docking part 9 to form a traction structure through the built-in guide wire rope component 8. The limiting docking part 9 forms a sliding structure along the inner side of the sound and light interactive buttons 2 through the second reset spring 10. The sound and light interactive button 2, equipped with a built-in battery, is controlled by a microcontroller program to illuminate in a specific sequence. Users can press the corresponding button 2 with their finger according to the illuminated state. The pressed button 2 will move along the inner side of the preset base 1. When the fixed top rod 5 nested inside the button 2 contacts the flexible insulating layer 6, the deformed flexible insulating layer 6 will cooperate with the fixed top rod 5 to contact the user's finger, indicating that the pressing pressure has reached the required level, and the user can release the button 2, simulating everyday use. In daily life, for tasks requiring fine motor skills such as single-finger clicking or alternating pressing, children can be informed whether their pressing pressure is adequate. As the interactive sound and light button 2 moves downward along the outside of the fixed top rod 5 under pressure, the fixed top rod 5 and the docking pre-reserved part 7, which are in a relatively fixed position, will drive the limiting docking part 9 to form a traction force state through the built-in guide steel wire rope component 8. As the interactive sound and light button 2 moves downward, the limiting docking part 9 can slide inward along the inside of the interactive sound and light button 2, thereby correcting the patient's finger pressing method and achieving the effect of controlling and adjusting the patient's pressing action to ensure standardization.

[0019] Example 2: Based on Example 1, an adaptive adjustment structure is also disclosed, the specific structure of which is as follows: An adaptive adjustment structure is provided between the preset base 1 and the sound and light interactive button 2, and the button triggering force of the sound and light interactive button 2 is controlled by the adaptive adjustment structure. The adaptive adjustment structure is equipped with a built-in vertical corrugated liquid bladder component 4, which is bonded to the inner side of the preset base 1. The upper end of the built-in vertical corrugated liquid bladder component 4 corresponds to the lower end of the sound and light interactive button 2. A fitting docking component 12 is nested inside the lower end of the preset base 1. The lower end of the fitting docking component 12 is connected to a threaded docking component 11, and the upper end of the fitting docking component 12 is connected to a docking reserved liquid bladder 13, which is located inside the preset base 1. A supply hose 14 is provided on the outer side of the docking reserved liquid bladder 13, and the supply hose 14 passes through the inner side of the preset base 1. The supply hose 14 and the built-in vertical corrugated liquid bladder component 4 are connected to each other. The threaded docking component 11 drives the fitting docking component 12 to move along the inner side of the preset base 1. A threaded rotation structure is formed on the inner side of the lower end of the preset base 1, and the mating docking part 12 applies pressure to the contacting docking reserved liquid bladder 13. According to training needs, the threaded docking part 11 can be held and the mating docking part 12 can be rotated along the inner side of the lower end of the preset base 1, so that the mating docking part 12 applies pressure to the contacting docking reserved liquid bladder 13, thereby allowing the docking reserved liquid bladder 13 to be supplied to the interior of the built-in vertical corrugated liquid bladder component 4 through the supply hose 14. The built-in vertical corrugated liquid bladder component 4 expands vertically and applies pressure to the lower end of the sound and light interactive button 2, increasing the force required for subsequent pressing of the sound and light interactive button 2. The button trigger force is set to a graded adjustable state, covering the needs of passive assistance training for children with severe disabilities to active resistance training for children with mild disabilities.
