Description

Technical Field

[0001] This utility model belongs to the field of assistive devices for patients with functional impairments, and specifically relates to a rehabilitation training wheelchair. Background Technology

[0002] Stroke, also known as apoplexy, is an acute cerebrovascular disease. Stroke patients experience unilateral limb and behavioral cognitive dysfunction, including decreased balance and coordination, leading to an inability to walk normally on their own. Unilateral neglect is one of the most common behavioral and cognitive impairments that immediately follows a stroke. It is characterized by loss of sensation on the affected side, failure to notice visual, auditory, and tactile sensations on the opposite side, accompanied by abnormalities in spatial orientation and other behavioral abilities. Current rehabilitation for stroke patients requires not only muscle-strengthening exercises but also intervention on the neglected side. Specifically, this involves training the neglected side's vision, touch, and spatial senses, mobilizing the neglected limbs, and increasing the patient's conscious attention to the neglected side. Because stroke patients have limited daily mobility and often use wheelchairs, their assisted training and interventions often require caregivers to assist them using appropriate equipment. However, rehabilitation for unilateral neglect is a long-term task. If the entire training process relies on real-time intervention and assistance from caregivers, the labor costs of care will increase significantly, and it will not meet the patient's need for continuous daily training. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rehabilitation training wheelchair that can be used as a daily mobility wheelchair and can better meet the needs of patients to perform limb training at any time and unilateral rehabilitation training that is neglected.

[0004] The present invention includes a wheelchair body, an elastic band, and an audio-visual mechanism. There are two elastic bands, which are located on opposite sides of the wheelchair body. One end of the elastic band is fixedly connected to one side of the wheelchair body, and the other end is detachably connected to the same side. The detachably connected end is used for the patient to hold and / or for fixing to the patient's limbs. The audio-visual mechanism is located on the side of the wheelchair body that is neglected by the patient and is used to emit sound and light.

[0005] Furthermore, the wheelchair body includes a frame, a seat cushion mounted on the frame, a backrest mounted on the frame, and armrests mounted on both sides of the frame. Two elastic bands are located on opposite sides of the frame, with one end of each elastic band fixedly connected to one side of the frame. The frame is fixedly connected to the two elastic bands at a position below the seat cushion.

[0006] Furthermore, the other end of the elastic band is detachably connected to one side of the frame, and the frame is detachably connected to the two elastic bands at the position below the seat.

[0007] Furthermore, one end of the elastic band that is detachably connected to the frame is looped, allowing the patient's hand to pass through.

[0008] Furthermore, the frame has hooks facing upwards, and one end of the elastic band is looped and can be hooked onto the hooks.

[0009] Furthermore, the sound and light mechanism includes a sound-emitting module and a light strip. The sound-emitting module is mounted on the frame and located on one side of the backrest, and the light strip is mounted on the armrest.

[0010] Furthermore, a flexible clip is provided on one side of the sound-generating module, allowing the sound-generating module to be detachably connected to the vehicle frame via the flexible clip.

[0011] Furthermore, the handrail includes a handrail body and a cover plate. The handrail body is provided with a storage cavity, the cover plate is detachably mounted on the top of the handrail body, and the light strip is detachably mounted on the cover plate.

[0012] Furthermore, it also includes connecting rods and elastic bands. There are two connecting rods, one end of which is rotatably connected to the two front sides of the frame, and the axis of rotation is set along the width direction of the frame. Each of the other ends of the two connecting rods is provided with a pedal for supporting the patient's feet. There are two elastic bands, one of which is connected between the frame and one of the connecting rods, and the other is connected between the frame and the other connecting rod.

[0013] Furthermore, the two pedals are provided with limiting elements to restrict the position of the patient's foot on the pedals.

[0014] The beneficial effects of this invention are that, after removing one detachable end of the two elastic bands, the other end remains fixedly connected to the wheelchair body. The patient can then hold and pull the two elastic bands with both hands to train the muscles and joints of their hands and arms. Alternatively, the detachable ends of the two elastic bands can be fixed to the patient's legs, allowing for leg muscle and joint training through leg-raising movements, thus accelerating rehabilitation. Since the elastic bands are located on both sides of the wheelchair body, compared to placing them on the backrest, this invention... The new elastic band, with its detachable connection at one end, not only makes it easier for patients to hold the band for hand and arm training, but also allows for leg training by using it in conjunction with leg-raising movements after it is fixed to the legs. This provides a wider training range and effectively utilizes the weight of the patient and the wheelchair to improve the overall stability of the wheelchair when using the elastic band for training. When not in use, the elastic band can be attached to the side of the wheelchair and move with it, making it easy to store and less likely to be lost. It allows patients to train anytime while in the wheelchair.

[0015] By installing a sound and light mechanism on one side of the wheelchair, sound and light can be emitted on the neglected side of the patient without real-time intervention from caregivers. This provides auxiliary stimulation and reminders to the neglected side, enhances the patient's conscious attention to the neglected side, achieves the effect of rehabilitation training, and reduces the labor cost of nursing care. Since wheelchairs are a device that stroke patients use for a long time and rely on daily, the above-mentioned setting allows this utility model to be used as a wheelchair for daily travel and to better meet the needs of patients to carry out limb training and unilateral neglect rehabilitation training at any time.

[0020] like Figures 1-3 As shown, this utility model includes a wheelchair body, elastic bands 5, and an audio-visual mechanism. There are two elastic bands 5, located on opposite sides of the wheelchair body. One end of each elastic band 5 is fixedly connected to one side of the wheelchair body, while the other end is detachably connected. The detachably connected ends of the two elastic bands 5 are used for patient gripping and / or for securing to the patient's limbs via binding. The audio-visual mechanism is located on the side of the wheelchair body that is neglected by the patient and is used to emit sound and light. For example, if the neglected side is the left side, the audio-visual mechanism is located on the left side of the wheelchair body.

[0021] The wheelchair provided by this utility model allows the detachable ends of the two elastic bands 5 to be removed, while the other ends remain fixedly connected to the wheelchair body. The patient can then hold and pull the two elastic bands 5 with both hands to train the muscles and joints of their hands and arms. Alternatively, the detachable ends of the two elastic bands 5 can be fixed to the patient's legs, allowing for leg muscle and joint training through leg-raising movements, thus accelerating rehabilitation. Since the elastic bands 5 are located on both sides of the wheelchair body, compared to placing them on the backrest 3, this utility model... The new elastic band 5, with its detachable connection at one end, not only makes it easier for patients to hold the elastic band 5 for hand and arm training, but also allows for leg training by using the elastic band 5 in conjunction with leg-raising movements after it is fixed to the legs. This provides a wider training range and effectively utilizes the weight of the patient and the wheelchair to improve the overall stability of the wheelchair when using the elastic band 5 for training. When not in use, the elastic band 5 can be attached to the side of the wheelchair and move with the wheelchair, making it easy to store and less likely to be lost. It allows patients to train anytime while in the wheelchair.

[0022] By installing a sound and light mechanism on one side of the wheelchair, sound and light can be emitted on the neglected side of the patient without real-time intervention from caregivers. This provides auxiliary stimulation and reminders to the neglected side, enhances the patient's conscious attention to the neglected side, achieves the effect of rehabilitation training, and reduces the labor cost of nursing care. Since wheelchairs are a device that stroke patients use for a long time and rely on daily, the above-mentioned setting allows this utility model to be used as a wheelchair for daily travel and to better meet the needs of patients to carry out limb training and unilateral neglect rehabilitation training at any time.

[0023] The wheelchair body includes a frame 1, a seat cushion 2 mounted on the frame 1, a backrest 3 mounted on the frame 1, and armrests 4 mounted on both sides of the frame 1. Two elastic bands 5 are specifically located on both sides of the frame 1, and one end of each elastic band 5 is fixedly connected to one side of the frame 1. That is, one end of each elastic band 5 is fixedly connected to both sides of the frame 1, and the position where the frame 1 is fixedly connected to the two elastic bands 5 is located below the seat cushion 2. Since the frame 1 is generally made of a strong, rigid material, this arrangement makes the fixed connection of the elastic band 5 more stable. At the same time, since the fixed connection is located below the seat cushion 2, compared with the method of setting the elastic band 5 on the armrest 4, in this utility model, on the one hand, when the patient pulls the elastic band 5, both hands can be in a completely hanging state, which is more in line with the natural position of the patient's arms in a sitting posture, which is conducive to the training of the arm muscles of the patient holding the elastic band 5. On the other hand, when using the elastic band 5 for leg training, this arrangement of the elastic band 5 ensures that its position is not higher than the leg position and is closer to the leg, which is convenient for fixing to the leg and also convenient for stretching the elastic band 5 when lifting the leg.

[0024] The other end of the elastic band 5 is detachably connected to one side of the frame 1 on which it is located. That is, the other ends of the two elastic bands 5 are fixedly connected to the two sides of the frame 1, and the position where the frame 1 and the two elastic bands 5 are detachably connected is located under the seat cushion 2. With this arrangement, when both ends of the elastic band 5 are connected to the frame 1, the entire elastic band 5 is located under the seat cushion 2. This can prevent the patient's clothing from getting caught on the elastic band 5, and can also prevent the detachable end of the elastic band 5 from coming loose due to the patient's body movement during wheelchair movement. This avoids the elastic band 5 coming loose during wheelchair movement and getting tangled or interfering with the wheels, thus making it more reliable in use.

[0025] The elastic band 5 is detachably connected to the frame 1 at one end, which is a ring that allows the patient's hand to pass through, making it easier for the patient to hold. For patients with weak hand gripping ability, the hand can be put inside the ring end for training.

[0026] The frame 1 has a hook 11 located in the area below the seat cushion 2. One end of the elastic band 5, which is looped, can be hooked onto the hook 11. This arrangement allows for a detachable connection at that end using the looped end of the elastic band 5 in conjunction with the hook 11, simplifying the detachable connection structure. Preferably, the hook 11 faces upwards. When the looped end of the elastic band 5 is hooked onto the hook 11, it can be stably hooked onto the hook 11 under the action of gravity. This reduces the complexity of the detachable structure and ensures that the end of the elastic band 5 is less likely to loosen naturally during wheelchair movement, preventing it from becoming entangled and interfering with the wheels.

[0027] The sound and light mechanism specifically includes a sound-emitting module 9 and a light strip 10. The sound-emitting module 9 is mounted on the frame 1 and located on one side of the backrest 3, closer to the ear on the side neglected by the patient. The light strip 10 is mounted on the armrest 4 on one side of the wheelchair body, specifically on the armrest 4 corresponding to the side neglected by the patient on one side. This arrangement ensures that the light emitted by the light strip 10 is within the patient's line of sight on the neglected side, providing effective unilateral stimulation and reminder.

[0028] like Figure 3As shown, an elastic clip 91 is provided on one side of the sound-generating module 9. The sound-generating module 9 is detachably connected to the frame 1 through the elastic clip 91, which facilitates changing the position of the sound-generating module 9 on the frame 1 according to the patient's neglected side, adapting to patients with different neglected sides. Specifically, the elastic clip 91 includes two clamping arms, both of which are arc-shaped and symmetrically arranged on one side of the sound-generating module 9. The two clamping arms are made of metal. Since the frame 1 is generally made of hollow metal tubes, in its natural state, the maximum distance between the two clamping arms in a single elastic clip 9 is less than the diameter of the hollow metal tube that makes the frame 1. When installing the sound-generating module 9, the two clamping arms in the elastic clip 91 are clamped on the frame 1 at the position on the side of the backrest 3. That is, the sound-generating module 9 is installed by clamping the hollow metal tube on the side of the backrest 3 in the frame 1 with the elastic clip 91. When it is necessary to remove the sound-generating module 9, at least one clamping arm of the elastic clip 91 is pried outward to loosen the clamping arm from the hollow metal tube, thereby removing the sound-generating module 9. The elastic clip 91 can be configured in two sets to improve stability during installation. The sound-emitting module 9 can be a speaker or audio device capable of playing audio, and the sound-emitting module 9 is either rechargeable or equipped with a battery for power supply.

[0029] In this invention, the armrest 4 includes an armrest body 41 and a cover plate 42. The armrest body 41 has a storage cavity, and the cover plate 42 is detachably mounted on the top of the armrest body 41, giving the armrest 4 an overall strip-shaped box structure. The detachable connection between the armrest body 41 and the cover plate 42 is similar to the fit between a conventional box and its lid. The cover plate 42 is pressed against the armrest body 41, and the storage cavity can be opened by applying a certain amount of force to lift the cover plate 42. In this configuration, the armrest 4 performs its original function while also utilizing its internal space as a storage space, serving a storage purpose. It can be used to place small hand gripping balls, hand grippers, and other training equipment for single-handed use, allowing patients to directly access these small devices for further training while in their wheelchairs. The light strip 10 is mounted on the cover plate 42 of one of the armrests 4, specifically along the length of the cover plate 42, ensuring that the light strip 10 is of sufficient size to provide sufficient brightness for stimulation. The light strip 10 is specifically an LED light strip assembled using FPC or PCB as the circuit board. A battery is also installed on the cover plate 42 where the light strip 10 is located to power the light strip 10. Since the cover plate 42 is detachably connected to the armrest body 41, the cover plate 42 with the light strip 10 can be swapped with another cover plate 42, that is, the cover plates 42 can be swapped on the two armrest bodies 41. This allows the light strip 10 to be adjusted to be on the left or right side of the wheelchair body to accommodate patients on different neglected sides.

[0030] In one embodiment of this utility model, the elastic band 5 simultaneously meets the training needs of both the upper and lower limbs, that is, both arm and leg training are carried out using the elastic band 5.

[0031] In another embodiment of this utility model, the utility model further includes a connecting rod 6 and an elastic band 8. There are two connecting rods 6, one end of which is rotatably connected to the two front sides of the frame 1, and the axis of rotation is set along the width direction of the frame 1. Each of the other ends of the two connecting rods 6 is provided with a pedal 7 for supporting the patient's feet. There are two elastic bands 8, one of which is connected between the frame 1 and one of the connecting rods 6, and the other is connected between the frame 1 and the other connecting rod 6. In this configuration, since the connecting rod 6 is rotatable, it has an upward swing stroke. The elastic band 8 provides resistance to the upward swing of the connecting rod 6. For patients with weak leg mobility and muscle strength in the early stages, when the patient sits on the wheelchair with both feet on the two footrests 7, the connecting rod 6 will swing downwards due to gravity. Limited by the frame 1 and seat 2, the connecting rod 6 will not swing excessively backward, thus not affecting the normal use of the footrests 7. By stepping on the footrests 7 and moving upwards, the elasticity generated by the stretching of the elastic band 8 can train the leg muscles, meeting the patient's training needs. In this embodiment, the elastic element 5 is only for upper limb training. The patient can directly step on the footrest 7 to extend their leg for training, without needing to fix the elastic element 5 to the patient's leg, reducing the difficulty of self-training. The elastic band 8 can be connected to the connecting rod 6 and the frame 1 by binding, facilitating assembly and disassembly. By using elastic bands 8 with different elasticities, the lower limb strength training needs at different rehabilitation stages can be met.

[0032] Limiting elements are provided on the two pedals 7 to restrict the position of the patient's foot on the pedals 7 and prevent the patient's foot from slipping on the pedals 7 when training with the help of the elastic band 8. The limiting elements can be side guard structures provided on the pedals 7, such as side guards provided at the front and rear ends and sides of the pedals 7 to prevent the foot from slipping off; in other configurations, the limiting elements can be straps provided on both sides of the pedals 7.

[0033] In one embodiment of the present invention, based on the above-described embodiment with pedals 7, two pedals 7 are fixedly mounted on two connecting rods 6.

[0034] In another configuration of this invention, two pedals 7 are rotatably mounted on two connecting rods 6. The rotation axes of the two pedals 7 are arranged along the width direction of the wheelchair body, meaning that the pedals 7 have a downward tilting stroke, allowing the patient to move their feet downwards when their feet are placed on the pedals 7, thus exercising the ankle joint. Preferably, this rotation stroke has a certain resistance, meaning that a certain force is required to drive the pedals 7 to rotate. For example, the rotational clearance is set to be small to prevent it from swinging naturally. When the patient sits on the wheelchair body with both feet on the two pedals 7, the pedals 7 adjust to the posture of the feet due to gravity. For patients with limited leg mobility or weak leg muscles who have difficulty actively lifting their legs, this invention allows them to tilt their feet downwards without lifting their feet off the pedals 7, thus exercising their ankle joints. For patients with some leg mobility but unable to actively lift their legs for extended periods, this invention allows them to train their ankle joints at any time. The pedals 7 not only satisfy the patient's need for active ankle training but also serve as a foot support structure.
