[0006] Preferably, the inflatable hard balancing pad includes a concave wear-resistant protective layer, the bottom of the wear-resistant protective layer is connected to the base layer, an inflatable hardened cavity layer is arranged on the base layer, and a surface layer is arranged on the inflatable hardened cavity layer; the inflatable hardened cavity layer is provided with five honeycomb inflatable units, one end of the honeycomb inflatable unit is connected to an electronic inflation valve, and the other end is connected to an electronic deflation valve, and the honeycomb inflatable unit is provided with an air pressure detector.

[0007] Preferably, the balance training device is provided with two pedal units, and two lifting platform devices are provided on the left and right of the pedal units; a basic base is provided at the bottom of the lifting platform device, and a cylinder lifting device is provided on the basic base. The support rod of the cylinder lifting device is connected to the support platform, and a contact layer is provided on the support platform. A positioning ring figure is marked in the middle of the pedal unit, and a pressure sensor is provided inside the ring.

[0008] Preferably, a pushing interference device is provided at the lower part of the left and right sides of the enclosure device, and the pushing interference device includes a pushing motor, and the pushing motor is connected to the pushing platform through a pushing rod. A rotating motor is provided inside the pushing platform, and the rotating motor is connected to the cam block through a rotating shaft. A pushing block is provided at the corresponding position of the cam block, and the pushing block is connected to the pushing platform through a spring.

[0009] Preferably, the base supports the ceiling through pillars, the ceiling is covered with an opaque tarpaulin, a lighting lamp is arranged in the middle of the ceiling, a laser projector is arranged at the rear, a tracking camera is arranged on one side of the laser projector, and a control host is arranged on one side of the base; a door is arranged at the rear of the enclosure, and a training ball is suspended from the ceiling by a rope.

[0010] Preferably, the control host is respectively connected to the lifting motor, light, audio, electronic inflation valve, electronic deflation valve, air pressure detector, cylinder controller, push motor, rotating motor, lighting, laser projector, tracking camera, infrared sensor, and control screen.

[0011] Preferably, a cylindrical handle is provided on the other side of the pulling block, and lights of different colors are provided inside.

[0012] The technical solution of the embodiment of the present invention has the following beneficial effects: The interactive device of the present invention mainly trains patients to maintain balance in the process of pulling the pulling block; in addition, the audio voice prompts the patient to pull the pulling block of specified color and number. The patient needs to judge the position of the pulling block and actively adjust the balance posture to pull the pulling block, which can encourage the patient to actively judge and think, that is, to exercise balance and prevent Alzheimer's disease; only after pulling the specified pulling block will the opposite rotating rod be pulled, which increases interference to the opponent and makes it easier to win; adding the interactive device can make the training process interesting, which is a kind of positive feedback for the patient.

[0013] The balance training device of the present invention can simulate scenes that are often encountered in daily life. The four cylinder lifting devices of the pedal unit rise and fall according to the program. The four can be lowered at the same time to simulate the scene of stepping on air. The two front ones are lifted for tiptoe training, and the left and right ones are lowered to simulate the state of not stepping firmly. After the sense of balance is improved, the lighting can be suddenly turned off during training or a pushing interference device can be added for pushing interference exercises.

[0014] The pushing interference device of the present invention can interfere with the patient's balance, and because the pushing platform is provided with a rotating motor and a cam block structure, the part of the patient pushed by the pushing block is random, which requires the patient to adjust through proprioception and can better exercise the patient's proprioception.

[0015] Typically, patients' vision is shielded by wearing eye masks or smart glasses with a shading function, but neither is as effective as this device. First, each patient's eye physiological conditions are different, and wearing smart glasses can cause discomfort. Eye masks require reminders to the patient to put them on or take them off, which is cumbersome to operate. Moreover, the patient is likely to guess that the interference device will be activated when it is pushed, which reduces the suddenness and consistency of the operation. This device uses a different method from the previous ones. It creates a dark environment with an opaque tarpaulin and then provides light through a lamp. When it is necessary to interfere with the patient's vision, the brightness is gradually reduced, and the patient does not need to operate or carry the device. Moreover, when the patient needs to restore vision, the brightness can be gradually increased, so that the patient will not experience rapid pupil constriction, causing temporary discomfort or dizziness.

[0016] This invention disrupts vision through light switches, proprioception through the balance training device, the push-disruption device, and the softness and hardness of the inflatable hard balance pad, and vestibular sense by pushing a training ball to designated positions on either side, causing the patient's head to twist and rotate. Patients can then perform targeted exercises based on their balance abilities. Incorporating distractions into balance training doesn't simply increase difficulty; it essentially activates the body's adaptive potential and compensatory mechanisms through sensory-motor stimulation, enabling patients to cope with more complex, real-life environments.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0028] A balance training device for a rehabilitation department comprises a base 1, an inflatable hard balance cushion 2 is arranged in the middle of the base 1, a protective device 3 is arranged at a corresponding position, and a balance training device 7 is arranged in the middle of the front of the inflatable hard balance cushion 2; an interactive device 4 is arranged at the front of the base 1, and the interactive device 4 comprises an interactive device body 41, rotating rods 42 are arranged at both ends of the interactive device body 41, and placement grooves 43 are arranged on both sides of the interactive device body 41; a pulling block 44 is arranged in the placement groove 43, and one end of the pulling block 44 is connected to a steel wire 45, and the steel wire 45 passes through a first pulley 416, a locking device 46, and a second pulley 47 in sequence to be connected to the rotating rod 42 on the opposite side; the rotating rod 42 is rotatably connected to the interactive device body 41 through a rotating shaft 48, and a torsion spring is arranged at the rotating shaft 48 for returning the rotating rod 42.

[0029] Pulling the pulling block 44 can cause the rotating rod 42 to rotate, causing balance disturbance to the patient opposite. In addition, four pulling blocks 44 are provided in this embodiment, the two on the left can control the rotating rod 42 on the left side of the opposite side, and the two on the right can control the rotating rod 42 on the right side of the opposite side.

[0030] The locking device 46 is fixed inside the interactive device body 41 through a fixed bracket 49. The bottom of the fixed bracket 49 is connected to the steel wire support platform 410. A lifting motor 411 is set on the upper part of the fixed bracket 49. The lifting platform 412 of the lifting motor 411 has a protrusion on the side. The protrusion is embedded in the groove 413 of the fixed bracket 49. A rubber pressing block 414 is provided at the bottom of the lifting platform 412. A groove is provided on the steel wire support platform 410 to facilitate the passage of the steel wire 45 and play a limiting role; the rubber pressing block 414 is arranged corresponding to the groove, so that the locking effect of the steel wire 45 is better.

[0031] A cylindrical handle is provided on the other side of the pulling block 44, and lights 415 of different colors are provided inside. In this embodiment, lights of four colors, red, yellow, blue and green, are provided. In addition, numbers are marked in sequence on the pulling block 44 to facilitate use by color-blind patients.

[0032] A speaker is provided on the side of the interactive device body 41 , and the speaker is connected to the laser projector 12 via Bluetooth to form a stereo sound.

[0033] The inflatable hard balancing pad 2 includes a concave wear-resistant protective layer 21, the bottom of the wear-resistant protective layer 21 is connected to a base layer 24, an inflatable hardened cavity layer 22 is provided on the base layer 24, and a surface layer 23 is provided on the inflatable hardened cavity layer 22, and the surface of the surface layer 23 is embossed with diamond-shaped convex dots; the inflatable hardened cavity layer 22 is provided with five honeycomb inflatable units, one end of each honeycomb inflatable unit is connected to an electronic inflation valve, and the other end is connected to an electronic deflation valve, and the honeycomb inflatable unit is provided with an air pressure detector; Wear-Resistant Protective Layer 21 is made of highly elastic TPU (thermoplastic polyurethane) or nylon fabric. It consists of multiple independent honeycomb-shaped inflatable cells, separated by heat sealing. The material is a composite film of polyester fiber and thermoplastic elastomer (TPE). In low-pressure mode, it acts like an elastic airbag, and in high-pressure mode, it acts like a solid rubber pad. The surface layer 23 is made of nylon and spandex, providing a soft, skin-friendly feel. The surface of the surface layer 23 is embossed with 0.2-0.4mm diamond-shaped bumps spaced 2-6mm apart to increase the coefficient of friction. Silver-ion-loaded zeolite is added to the surface layer 23 to enhance antimicrobial properties and reduce the risk of cross-infection.

[0034] The balance training device 7 is provided with two foot pedal units 77. Each of the left and right sides of the foot pedal unit 77 is provided with two lifting platform devices 74, forming a cross shape. The bottom of the lifting platform device 74 is provided with a base pedestal 75. A cylinder lifting device 73 is provided on the base pedestal 75. The support rod of the cylinder lifting device 73 is connected to a support platform 72. A contact layer 71 is arranged on the support platform 72, and the contact layer 71 only needs to be skin-friendly and soft. A positioning ring pattern is marked in the middle of the foot pedal unit 77, and a pressure sensor 76 is arranged inside the ring. The structure of the cylinder lifting device 73 is a conventional device, but the four cylinder lifting devices 73 are connected to a cylinder controller so that they can work in coordination, that is, they are connected to the control host 15.

[0035] On the lower parts of the left and right sides of the enclosure device 3, a pushing interference device 5 is arranged. The pushing interference device 5 includes a pushing motor 51. The pushing motor 51 is connected to a pushing platform 57 through a pushing rod. A rotating motor 53 is arranged inside the pushing platform 57. The rotating motor 53 is connected to a cam block 55 through a rotating shaft 54. A pushing block 56 is arranged at the corresponding position of the cam block 55. The pushing block 56 is connected to the pushing platform 57 through a spring. That is, the position and strength of pushing the patient are random, and the patient needs to rely on instinctive reactions to maintain balance. An infrared sensor 52 is arranged on the top of the pushing platform 57. The infrared sensor 52 mainly checks whether the patient has entered the designated position.

[0036] The base 1 supports the ceiling 9 through four columns 8. The ceiling 9 is covered with an opaque tarpaulin 10. A lighting lamp 11 is arranged in the middle of the ceiling 9, and a laser projector 12 is arranged at the rear. A tracking camera 13 is arranged on one side of the laser projector 12. Usually, to shield the patient's vision, wearing an eye mask or smart glasses with a light-shielding function is adopted, but neither is as good as this device. First, the eye physiological conditions of each patient are different, and wearing smart glasses will cause discomfort. And the eye mask needs to remind the patient to put it on or take it off, which is very cumbersome during operation. Moreover, the patient will probably guess that the pushing interference device 5 is about to operate, reducing the suddenness and coherence. And this device adopts a method different from the past. It creates a dark environment through the opaque tarpaulin 10 and then provides light through the lighting lamp 11. When it is necessary to interfere with the patient's vision, the brightness is gradually reduced without the need for the patient to operate or carry a device. And when it is necessary for the patient to restore vision, the brightness can be gradually increased so that the patient will not have rapid pupil contraction, causing transient discomfort or dizziness.

[0037] The ceiling 9 is suspended with a fresh air conditioner 14, and a control host 15 is arranged on one side of the base 1. A door 6 is arranged at the rear of the enclosure device 3. The ceiling 9 suspends a training ball 16 through a rope.

[0038] The control host 15 is connected to the lifting motor 411, light 415, audio system, electronic inflation valve, electronic deflation valve, air pressure gauge, cylinder controller, push motor 51, rotation motor 53, lighting 11, laser projector 12, tracking camera 13, infrared sensor 52, and a control screen. The control screen is used to control the difficulty level of the device and monitor the patient to ensure their safety. Another type of balance training device for rehabilitation uses a soft surface material to protect the patient from bumps and scratches.

[0039] The lifting motor 411 and the pushing motor 51 both adopt a screw rod lifting structure.

[0040] The device is used as follows: The patient enters a balance training device of the rehabilitation department and enters the inflatable hard balance cushion 2 through the door 6; during the initial recovery period of the patient, the ability to stand and balance in the inflatable hard balance cushion 2 can be improved. The inflation amount of the inflatable hard balance cushion 2 can be adjusted according to the patient's rehabilitation condition, and the hardness of the inflatable hard balance cushion 2 can be controlled to adjust the strength of the balance. Of course, you can also try to use a single leg for balance exercises, and you can also increase the movement of the push training ball 16 to maintain the balance of the body in a dynamic situation; the pushing interference device 5 is randomly opened from the left and right sides to interfere with the patient's balance, and because the pushing platform 57 is provided with a rotating motor 53 and a cam block 55 structure, the part of the patient pushed by the pushing block 56 is random, which requires the patient to make adjustments through proprioception, and can better exercise the patient's proprioception.

[0041] During the mid-stage of rehabilitation, the difficulty can be increased appropriately. For example, while standing on one foot on a relatively hard, inflatable balance mat 2, the light 11 can be suddenly turned off to train the patient's proprioception and vestibular sense. The time for the light 11 to be turned off can be dynamically set according to the patient's ability. A push-interference device 5 can also be added to the training to increase the intensity. Following the prompts from the laser projector 12, the patient can push the training ball 16 to designated positions on both sides, forcing the patient to twist and rotate their head, which in turn stimulates the patient's vestibular sense. The patient uses proprioception and vision to balance, training their ability to work together.

[0042] When entering the middle and late stages of rehabilitation, you can stand on the balance training device 7 to practice. The four cylinder lifting devices 73 of the pedal unit 77 rise and fall according to the program. The four can be lowered at the same time to simulate the scene of stepping on air. The two front ones are lifted for tiptoe training, and the left and right ones are lowered to simulate the state of not stepping firmly. After the sense of balance is improved, you can suddenly turn off the lighting 11 during training or add the push interference device 5 to push interference exercises.

[0043] The rehabilitation process is very boring, so the training process becomes interesting. The tarpaulin at the interactive device 44 is rolled up so that both parties can see each other; the patient maintains balance while the balance training device 7 is working, and the audio prompts the patient to pull the pull block 44 of the specified color and number. Only by pulling the pull block 44 that meets the requirements will the opposite rotating rod 42 be pulled. The other pull blocks 44 will be locked by their respective locking devices 46, and the wrong pull block 44 cannot be pulled. This increases the rigor of the game and can prevent Alzheimer's disease. Four pressure sensors 76 form a group, and two groups determine the status of the two feet. That is, if the pressure of all pressure sensors 76 in any group reaches zero, it is considered a failure.

[0044] The laser projector 12 guides the patient to move, and uses the tracking camera 13 to determine whether the patient has reached the designated position, whether the training ball 16 has been thrown in the designated direction, whether the patient has fallen, etc.

[0045] In addition, the laser projector 12 can project dynamic images, and the images are opposite to the rising and falling states of the balance training device 7. For example, when the image plays a falling scene, the balance training device 7 rises instead. This can force the brain to strengthen the neural adaptability through "error correction", which is similar to the "mirror therapy" in sports rehabilitation.

[0046] This device can help patients with nerve damage, orthopedic surgery, etc. to exercise their balance ability, covering almost the entire recovery cycle.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form or substance. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the method of the present invention. These improvements and supplements should also be regarded as the scope of protection of the present invention. Any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the spirit and scope of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of the technical solution of the present invention.
