Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training equipment technology, and in particular to a balance training auxiliary device for rehabilitation. Background Technology

[0002] In the rehabilitation process of long-term bedridden patients, early rehabilitation measures are of great significance in reducing the harm caused by immobilization and improving the patient's quality of life. Among them, bedside sitting balance training, as an effective postural care and early rehabilitation method, is widely used in clinical practice. This training method, by placing the patient in a sitting position, can specifically exercise their core muscle groups, especially the abdominal core muscles, thereby effectively reducing the occurrence of disuse syndrome and promoting the recovery of the patient's physical functions.

[0003] However, in practice, bedside sitting balance training faces a series of challenges. Especially for patients with poor sitting balance, they often struggle to maintain a stable posture and are prone to losing their balance during training. To ensure patient safety, multiple caregivers are usually needed to assist in stabilizing the patient's body and ensure the training proceeds smoothly. This training method, reliant on caregiver support, not only increases labor costs but may also lead to patients becoming overly dependent on external support during training, preventing them from effectively perceiving and exercising their own muscle strength.

[0004] In addition, caregivers often find it difficult to accurately judge whether patients are actually exerting force when assisting them with training, which further affects the training effect and the patient's rehabilitation process. Utility Model Content

[0005] To overcome at least one of the defects described in the prior art, this invention provides a balance training aid for rehabilitation. It allows for observation of whether the patient is exerting force independently without requiring numerous caregivers to stabilize the patient's body, enabling doctors to accurately determine whether the patient is using force.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A balance training assistive device for rehabilitation includes: a seat frame, the seat frame including a backrest, armrests and a seat cushion, the armrests being connected between the backrest and the seat cushion; a flexible pad, the flexible pad being wrapped around the backrest and / or the seat cushion and / or the armrests; a shoulder limiting frame, the shoulder limiting frame including an adjusting rod and an auxiliary component, one end of the adjusting rod being fixed to the seat frame and the other end being connected to the auxiliary component, the auxiliary component facing the backrest being used to abut against the front of the user's shoulder to provide frontal auxiliary support for the user; a gravity sensor, the gravity sensor being disposed on the auxiliary component facing the backrest and on the backrest; a response unit, the response unit being connected to a controller, the controller being electrically connected to the gravity sensor, the controller controlling the response unit to operate when the gravity signal received by the gravity sensor exceeds a threshold.

[0008] By adopting the above solution, the backrest, armrests, seat cushion, and shoulder restraint frame can provide users with multi-directional auxiliary support, reducing reliance on caregivers. The design of the adjustable linkage and auxiliary components allows the shoulder restraint frame to be adjusted according to the patient's height and body shape, thus providing personalized support. When the gravity signal received by the gravity sensor exceeds the preset threshold, the controller will control the response unit to work, such as issuing an audible prompt or visual signal, thereby reminding the patient and doctor whether the patient is exerting force, helping to improve the training effect, promote the recovery of the patient's physical functions, and thus improve the quality of the patient's rehabilitation.

[0009] Furthermore, the adjusting linkage includes: a first support rod having a slot; a second support rod inserted into the slot; and a rotating adjusting member rotatably connected between the first support rod and the second support rod, for providing a locking force to the first support rod and the second support rod.

[0010] By adopting the above solution, the rotating adjustment component is a key part connecting the first support rod and the second support rod. It is usually a threaded knob or similar fastener. This locking mechanism ensures the stability and safety of the shoulder limiting frame and provides reliable support for the patient.

[0011] Furthermore, a hinge mechanism is provided between the auxiliary component and the adjusting rod to adjust the included angle between the auxiliary component and the adjusting rod.

[0012] By adopting the above scheme, the angle of the auxiliary component relative to the adjusting linkage can be adjusted, thereby further increasing the flexibility and adaptability of the device. By adjusting the included angle, it can be ensured that the shoulder limiting frame always fits the patient's shoulder, reducing discomfort and improving training comfort.

[0013] Furthermore, the hinge mechanism includes: a hinge rod, one end of which is provided with a hinge groove, and the end of the adjusting link is provided with a hinge joint hinged to the hinge groove; and a locking member, which is used to lock the hinge groove and the hinge joint.

[0014] By adopting the above solution, the combined use of the hinge rod and the locking component can ensure the stability of the device during training and prevent safety hazards caused by changes in the included angle.

[0015] Furthermore, the locking member includes: a first locking member having an outwardly protruding threaded rod; and a second locking member having an inwardly recessed threaded groove, wherein the threaded rod is threadedly connected to the threaded groove.

[0016] By adopting the above scheme, as the threaded rod and the threaded groove are gradually tightened, the gap between the hinge groove and the hinge joint is gradually eliminated, thereby achieving a stable locking effect.

[0017] Furthermore, the armrest is provided with a rotatably connected tabletop unit, which is used to provide auxiliary support for the user.

[0018] By adopting the above solution, the main function of the tabletop unit is to provide auxiliary support for the user, reduce the burden on the arms and shoulders, and improve training comfort. In addition, the tabletop unit can also serve as a temporary desktop for writing, reading, or eating, increasing the practicality and convenience of the device.

[0019] Furthermore, the tabletop unit includes: a first tabletop; a second tabletop; a pivot rod passing through the first tabletop and the second tabletop to enable the first tabletop and the second tabletop to rotate about the pivot rod as an axis; and a fixing member for fixing the pivot rod to the armrest portion.

[0020] By adopting the above solution, the tabletop unit can be flexibly adjusted according to the user's actual needs, such as changing the angle or direction of the desktop to adapt to different usage scenarios.

[0021] Furthermore, the seat frame also includes a support portion located below the seat cushion portion.

[0022] By adopting the above solution, the support part is located below the seat cushion, which plays a role in supporting and stabilizing the seat cushion, ensuring the stability and durability of the seat.

[0023] Furthermore, a brake caster is provided below the support portion.

[0024] By adopting the above design, the brake casters allow the entire assistive device to be easily moved between different locations. Whether for indoor rehabilitation training or when the device needs to be moved outdoors for activities, the brake casters provide sufficient flexibility.

[0025] Furthermore, the response unit includes a flashing light and / or an alarm.

[0026] By employing the above scheme, the flashing light, emitting bright and eye-catching light, can immediately attract the user's visual attention. When the user becomes unbalanced or has an incorrect posture during training, the flashing light can quickly illuminate to remind the user to make adjustments; the alarm, emitting a loud sound, can immediately attract the user's auditory attention. When the user encounters a dangerous situation or needs to stop urgently during training, the alarm can quickly sound to remind the user to take action.

[0027] In summary, the balance training assistive device for rehabilitation provided by this utility model has the following technical effects:

[0028] 1. This assistive device significantly reduces reliance on caregivers by providing comprehensive support, including backrest, armrests, seat cushion, and shoulder restraint frame. This means that during training, multiple caregivers are not required to stabilize the patient's body, thereby reducing labor costs and alleviating the burden on caregivers.

[0029] 2. The shoulder support frame is designed with adjustable links and auxiliary components, allowing the device to be adjusted according to the patient's height and body type, providing personalized support. This personalized support ensures the patient maintains a stable sitting posture during training, reducing the risk of loss of balance and thus improving training effectiveness.

[0030] 3. The device is equipped with a gravity sensor and a response unit.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] See Embodiment 1 of this utility model. Figures 1-4 As shown, a balance training assistive device for rehabilitation is disclosed, including a seat frame 1, a flexible pad 2, a shoulder limiting frame 3, a gravity sensor 4, and a response unit 5. The seat frame 1 includes a backrest 11, an armrest 12, and a seat cushion 13. The armrest 12 is connected between the backrest 11 and the seat cushion 13. The flexible pad 2 is wrapped around the backrest 11 and / or the seat cushion 13 and / or the armrest 12. Specifically, in this embodiment 1, the backrest 11, armrest 12, and seat cushion 13 are all spliced ​​from square steel or steel pipes. The flexible pad 2 is preferably a leather pad with a foam layer. In other embodiments, the specific structure of the backrest 11, armrest 12, and seat cushion 13 is not limited, and the material of the flexible pad 2 is not specifically limited. The shoulder limiting frame 3 includes an adjusting link 31 and an auxiliary component 32. One end of the adjusting link 31 is fixed to the seat frame 1, and the other end is connected to the auxiliary component 32. The auxiliary component 32 is positioned on the side facing the backrest 11 to abut against the front of the user's shoulder, providing frontal support. The gravity sensor 4 is located on the side of the auxiliary component 32 facing the backrest 11 and on the backrest 11. The response unit 5 is connected to a controller 53, which is electrically connected to the gravity sensor 4. When the gravity signal received by the gravity sensor 4 exceeds a threshold, the controller 53 controls the response unit 5 to operate, such as issuing an audible prompt or visual signal, thereby reminding the patient and doctor whether the patient is exerting force, helping to improve training effectiveness, promoting the recovery of the patient's physical functions, and thus improving the quality of the patient's rehabilitation.

[0042] To facilitate adjustment of the position and state of the shoulder limiting frame 3, in some embodiments, the adjusting linkage 31 includes a first support rod 311, a second support rod 312, and a rotating adjusting member 313. The first support rod 311 has a slot 3111, and the second support rod 312 is inserted into the slot 3111. The rotating adjusting member 313 is rotatably connected between the first support rod 311 and the second support rod 312, providing a locking force for the first support rod 311 and the second support rod 312. The rotating adjusting member 313 is a key component connecting the first support rod 311 and the second support rod 312. Preferably, the rotating adjusting member 313 is a threaded knob or similar fastener. This locking mechanism ensures the stability and safety of the shoulder limiting frame 3, providing reliable support for the patient. In this embodiment 1, the shoulder limiting frame 3 is provided in two sets, located at the top ends of the backrest 11, respectively.

[0043] In use, the control adjustment component 313 is rotated to unlock, allowing the first support rod 311 and the second support rod 312 to rotate relative to each other. This opens the two sets of shoulder limiting frames 3 by rotating the second support rods 312 away from each other, allowing the patient to sit directly on the seat cushion 13. Then, the two sets of shoulder limiting frames 3 are brought closer together to close, causing the auxiliary component 32 to rotate to the front of the patient's shoulder. The relative height between the first support rod 311 and the second support rod 312 is then adjusted according to the patient's upper body length. The control adjustment component 313 is then rotated to tighten, completing the auxiliary fixation of the patient. At this point, the gravity sensor 4 can detect whether the patient is fully leaning. When fully leaning, the response unit 5 provides a corresponding prompt to the user or physician, encouraging the patient to engage in strength training.

[0044] In some embodiments, a hinge mechanism 33 is provided between the auxiliary member 32 and the adjusting link 31 to adjust the included angle between the auxiliary member 32 and the adjusting link 31. This configuration allows the auxiliary member 32 to be adjusted relative to the adjusting link 31, thereby further increasing the flexibility and adaptability of the device. By adjusting the included angle, it can be ensured that the shoulder limiting frame 3 always fits the patient's shoulder, reducing discomfort and improving training comfort.

[0045] In this embodiment 1, the hinge mechanism 33 includes a hinge rod 331 and a locking member 332. One end of the hinge rod 331 is provided with a hinge groove 3311, and the end of the adjusting rod 31 is provided with a hinge joint 3121 that is hinged to the hinge groove 3311. The locking member 332 is used to lock the hinge groove 3311 and the hinge joint 3121. The combined use of the hinge rod 331 and the locking member 332 can ensure the stability of the device during training and prevent safety hazards caused by changes in the included angle. Preferably, the locking member 332 includes a first locking member 3321 and a second locking member 3323. The first locking member 3321 has an outwardly protruding threaded rod 3322, and the second locking member 3323 has an inwardly recessed threaded groove 3324. The threaded rod 3322 is threadedly connected to the threaded groove 3324. As the threaded rod 3322 and the threaded groove 3324 are gradually tightened, the gap between the hinge groove 3311 and the hinge joint 3121 is gradually eliminated, thereby achieving a stable locking effect. In other embodiments, the locking member 332 can be other structures, which are not specifically limited in this embodiment.

[0046] When users train, they typically can only use their hands to hold onto the armrests 12 for assisted posture adjustment and balance, which places high demands on the patient's force control. Therefore, in some embodiments, a rotatably connected tabletop unit 6 is provided on the armrests 12. The tabletop unit 6 provides auxiliary support for the user; the patient can lean on the tabletop unit 6 with their elbows or arms to reduce the burden on their arms and shoulders. Compared to gripping the armrests 12, it is easier to maintain a sitting posture, thereby improving training comfort. Furthermore, the tabletop unit 6 can also serve as a temporary table for writing, reading, or eating, increasing the practicality and convenience of the device.

[0047] In some embodiments, the tabletop unit 6 includes a first tabletop 61, a second tabletop 62, a pivot rod 63, and a fixing member 64. The pivot rod 63 passes through the first tabletop 61 and the second tabletop 62, allowing the first tabletop 61 and the second tabletop 62 to rotate about the pivot rod 63. The fixing member 64 is used to fix the pivot rod to the armrest portion 12, so that the tabletop unit 6 can be flexibly adjusted according to the user's actual needs, such as changing the angle or direction of the desktop to adapt to different usage scenarios. Preferably, the fixing member 64 is a nut. By setting the first tabletop 61 and the second tabletop 62, two desktop heights can be provided for the user to choose from. In other embodiments, one or more tabletops can be set, which is not specifically limited in this embodiment.

[0048] In this embodiment 1, the tabletop unit 6 is provided on both armrests 12, allowing each tabletop unit 6 to be rotated and opened independently, reducing the space occupied by a single tabletop unit 6 and facilitating overall storage. In other embodiments, the tabletop unit 6 may include, but is not limited to, a folding tabletop or an electrically adjustable tabletop, as long as it provides support and multiple functions for the user.

[0049] In this embodiment 1, the seat frame 1 further includes a support portion 14, which is located below the seat cushion portion 13. The support portion 14 is also constructed from square steel or steel tubing, and its location below the seat cushion portion 13 serves to support and stabilize it, ensuring the stability and durability of the seat. Optionally, a brake caster 15 is provided below the support portion 14. The design of the brake caster 15 allows the entire auxiliary device to be easily moved between different locations. Whether for indoor rehabilitation training or when the device needs to be moved outdoors for activities, the brake caster 15 provides sufficient flexibility.

[0050] It should be noted that the materials of the support part 14, the backrest 11, and the armrest part 12 are not fixed and can be replaced with other materials.

[0051] In some embodiments, the response unit 5 optionally includes a flashing light 51 and / or an alarm 52. The flashing light 51, by emitting a bright and eye-catching light, can immediately attract the user's attention visually. When the user becomes unbalanced or has an incorrect posture during training, the flashing light 51 can quickly illuminate to remind the user to make adjustments. The alarm 52, by emitting a loud sound, can immediately attract the user's attention audibly. When the user encounters a dangerous situation or needs to stop urgently during training, the alarm 52 can quickly sound to remind the user to take action.

[0052] In this embodiment 1, the response unit 5 is disposed on the auxiliary component 32. The auxiliary component 32, from one side to the other, includes a lampshade 56, a flashing light 51, an alarm, a circuit board 54 with a controller 53, a gravity sensor 4, and a housing 57. The circuit board 54 is also connected to a power supply 55, which can be an external power supply, a rechargeable battery, or a dry cell battery. Preferably, the flashing light 51 includes a yellow light, a red light, and a green light. The working principle of the response unit 5 is as follows: First, the gravity sensor 4 detects the weight the user is leaning against. When the gravity sensor 4 shifts or deforms, the electrical signal is amplified by the amplification circuit 541 on the circuit board 54, and noise is removed by the filtering circuit 542. Then, the analog signal is converted into a digital signal by the A / D conversion circuit 543. The input terminal of the controller 53 receives the digital signal output by the A / D converter and makes a judgment on whether it is the maximum threshold. The maximum threshold is the gravity value that the doctor adds when the user is fully leaning against. When the digital signal is between 0 and the maximum threshold, it proves that the patient has partial support. It can provide some auxiliary practice effect. At this time, the controller 53 outputs a control signal to make the yellow light inside the lampshade 56 light up. When the digital signal is 0, it proves that the patient is completely independent and can achieve the practice effect. At this time, the controller 53 outputs a control signal to make the green light inside the lampshade 56 light up. When the digital signal is greater than the maximum threshold, it proves that the patient is completely leaning and not exerting force, and cannot achieve the practice effect. At this time, the controller 53 outputs a control signal to make the red light inside the lampshade 56 light up and activate the generation module in the alarm 52. The sound is including but not limited to the phoenix sound or the preset sound or voice information of the sound broadcast module.

[0053] In other embodiments, only two lights may be provided, for example, a red light when the patient is completely dependent on the device, and a green light when the patient uses their own strength to maintain balance.

[0055] 1. This assistive device, by providing comprehensive support including a backrest 11, armrests 12, seat cushion 13, and shoulder restraint frame 3, can significantly reduce reliance on caregivers.
