Description

Technical Field

[0001] This invention relates to the field of walking aids, specifically to a walking aid for patients undergoing exercise in neurology nursing. Background Technology

[0002] Patients with neurological conditions such as stroke and Parkinson's disease often experience limb motor dysfunction, especially impaired walking ability. Scientific walking exercises are crucial for promoting neurological function recovery, maintaining muscle strength, improving limb coordination, and enhancing self-care abilities. Assistive devices are essential aids during these exercises, providing stable support, helping patients maintain balance, and reducing the risk of falls. The most widely used assistive device is the walking frame, which typically employs a gate-like support structure with a stable overall frame. Wheels are usually mounted at the bottom of the frame for easy movement. When using this type of walking frame, patients support themselves with their hands on the handrails on either side, using their arms to maintain stability. They can then push the frame slowly, coordinating with their lower limbs to complete stepping movements, thus achieving walking training.

[0003] However, the existing technology has the following problems: When patients use a walking frame for walking exercises, the walking frame is prone to shaking when the ground in the walking area is uneven or there are debris. Because patients have relatively weak lower limb strength and poor balance, the shaking of the walking frame can easily cause patients to lose their balance and thus risk falling. Summary of the Invention

[0004] The purpose of this invention is to provide a patient exercise assistive device for neurological nursing in order to solve the above-mentioned problems, so as to overcome the defects of existing walking frames that are prone to shaking. Because patients have relatively weak lower limb strength and poor body balance, when the walking frame shakes, the patient's body is easily affected by the shaking and loses balance. Details are described below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a patient exercise assistance device for neurological nursing, comprising a support frame; a movement component is provided at the bottom of the support frame, the movement component including a set of first damping shock absorbers, one end of the first damping shock absorbers being fixedly connected to the bottom of the support frame, and the other end of the first damping shock absorbers being fixedly connected to a frame, the bottom of the frame being equipped with four first omnidirectional wheels; a balance component is provided on the inner side of the support frame, the balance component including two rocker arms, the top of the rocker arms being equipped with a support plate, the support plate being able to move towards the patient and provide support when the patient's body is tilted to the side; a seat assembly is provided on the support frame, the seat assembly including two rotating frames, the two rotating frames being respectively fixedly connected with a half-seat cushion and a half-lumbar support, the two rotating frames being able to open and close by the patient's manual operation, the two rotating frames being able to form a complete seat cushion and lumbar support when closed.

[0006] Preferably, the top of the support frame is connected to a top frame, the top frame is provided with two sponge hand rests, the height of the top frame can be adjusted by extending and retracting on the support frame, and a limiting mechanism for fixing the height of the top frame is provided between the top frame and the support frame.

[0007] Preferably, the frame has two slides fixedly connected in a mirror image, each slide has a strut hinged to it, and a support block is fixedly connected to the end of the strut away from the slide. A contact block is horizontally slidably connected to the slide, and a first connecting rod is hinged between the contact block and the bottom of the support frame. A first leaf spring is provided between the strut and the slide. When the distance between the bottom of the support frame and the frame is shortened, the strut can be driven to swing downward through the first connecting rod and the contact block.

[0008] Preferably, the two rocker arms are hinged to the inside of the support frame, and two portal frames are fixedly installed on the support frame. Two pairs of second connecting rods are hinged to the portal frames, and a flat plate is hinged to the end of the two pairs of second connecting rods away from the portal frames. Multiple first springs are provided between the flat plate and the portal frames, and a coil spring is provided at the hinge point between the rocker arms and the support frame. The ends of the two rocker arms away from the support plates respectively abut against the two flat plates. The two flat plates and the two support plates are mirror images of each other.

[0009] Preferably, the support plate can be adjusted in height by extending and retracting the top of the rocker arm, and a limiting mechanism for fixing the height of the support plate is provided between the support plate and the rocker arm.

[0010] Preferably, both rotating frames are hinged to a support frame. Two sliding sleeves are horizontally slidably connected to the support frame. A third connecting rod is hinged between the two sliding sleeves and the two rotating frames. A telescopic rod is hinged to the sliding sleeve. A handle is fixedly connected to the top of the telescopic rod. Two slotted plates are fixedly connected to the outer wall of the top frame. Movable slots are formed on the slotted plates. The two telescopic rods are respectively located in the movable slots of the two slotted plates. The telescopic rods can extend and retract. The handle is located above the slotted plates. During the sliding process of the telescopic rods in the movable slots of the slotted plates, they can drive the sliding sleeves to move closer to the rotating frames. When the two sliding sleeves move closer to the rotating frames, they drive the two rotating frames to merge through the two third connecting rods.

[0011] Preferably, the movable groove of the slot plate is divided into a sliding groove and two limiting grooves. The sliding groove is located between the two limiting grooves. A limiting rod is horizontally slidably connected to the slot plate. A lever is provided at the top of the limiting rod. The limiting rod can block one of the limiting grooves of the slot plate by sliding. When the limiting rod blocks the limiting groove, it can lock the telescopic rod in the limiting groove.

[0012] Preferably, a right-angle rod is fixedly installed at the bottom of the rotating frame, and a second damping shock absorber rod is fixedly connected to the bottom end of the right-angle rod. A second omnidirectional wheel is installed at the bottom end of the second damping shock absorber rod.

[0013] Preferably, the right-angle rod is provided with an anti-reverse mechanism, which includes a slider, a sliding rod, and a wheel frame. The slider is horizontally slidably connected to the top of the right-angle rod, and a second spring is provided between the slider and the top of the right-angle rod. The sliding rod is vertically slidably connected to the side wall of the right-angle rod, and a fourth connecting rod is hinged between the sliding rod and the slider. The wheel frame is hinged to the top of the second damping shock absorber rod, and a one-way roller is rotatably mounted on the wheel frame. A deflector is connected to the sliding rod, and a slot is provided on the wheel frame. The deflector is slidably connected to the slot of the wheel frame. The slider protrudes from the top of the right-angle rod. When the two right-angle rods are combined, the two sliders can contact and press against each other. When the two sliders press against each other, they respectively drive the sliding rod to move downward through the fourth connecting rod. The downward movement of the deflector can drive the wheel frame to swing downward through the slot.

[0014] The beneficial effects are: 1. This neurological nursing patient exercise assistive device, through the setting of the movement components, enables multiple first damping shock absorbers to effectively reduce the transmission of vibration to the support frame and the patient's body, avoiding vibration causing the patient's body to lose balance. When the patient's center of gravity is unstable or the legs are weak during the assistive walking process, causing the body to press down, two support blocks automatically contact the ground and form a support point, effectively dispersing the force on the bottom of the frame, preventing the support frame from tipping over or sliding, and making it easier for the patient to adjust the center of gravity and restore leg strength.

[0015] 2. This neurological nursing patient exercise assistive device, through the setting of the balance component, enables the support board in the direction of the patient's tilt to automatically approach the patient's torso and support the patient when the patient's body tilts to the side due to lateral bending of the legs during the assistive walking process, preventing the patient's body from tilting further to the side. The patient can easily restore upright posture by using the support force of the support board and the support of both arms. After the patient restores upright posture, the support board returns to its original position without affecting the patient's walking.

[0016] 3. This patient exercise assistive device for neurological nursing uses a seat assembly that allows patients to pull two handles to drive two rotating frames to merge into a complete seat and lumbar support when they need to rest during walking. The seat and lumbar support are positioned behind the patient, providing support for rest at any time, allowing the patient to simply sit back on the seat when they need to rest.

[0017] 4. This patient exercise assistive device for neurology nursing uses an anti-reverse mechanism that allows the two one-way rollers to automatically move downwards after the two rotating frames are combined, forming a friction surface with the ground to achieve a parking effect. In this state, the support frame can only move forward and not backward, preventing the support frame from moving backward while the patient is resting or moving, which could cause the patient to lose balance and fall backward.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] One embodiment of the present invention is as follows: Please see Figure 1 - Figure 3A patient exercise assistive device for neurological nursing includes a support frame 1. A movement component 2 is located at the bottom of the support frame 1. The movement component 2 includes a set of first damping shock absorbers 21. One end of each set of first damping shock absorbers 21 is fixedly connected to the bottom of the support frame 1, and the other end is fixedly connected to a frame 22. Four first omnidirectional wheels 23 are mounted on the bottom of the frame 22. A top frame 11 is connected to the top of the support frame 1, and two sponge hand rests are provided on the top frame 11. The support frame 1 provides a stable support frame for the patient. The first damping shock absorbers 21 employ a damping buffer structure. When the patient pushes the device... When moving on uneven ground, the vibration transmitted from the ground is transmitted to the frame 22 through the first universal wheel 23, and then acts on the first damping shock absorber 21. The damping medium inside the rod consumes the vibration energy through friction and viscosity, effectively slowing down the transmission of vibration to the support frame 1 and the patient's body, and preventing the vibration from causing the patient to lose balance. The patient stands inside the support frame 1 and supports his two forearms on the two sponge hand rests of the top frame 11. He supports his body with his arms and applies force to the top frame 11, thereby pushing the support frame 1 to move. The four first universal wheels 23 can turn freely, which facilitates the patient's turning operation.

[0023] Furthermore, please refer to Figure 3 The top frame 11 can be height-adjusted by telescopic extension on the support frame 1. A limiting mechanism for fixing the height of the top frame 11 is provided between the top frame 11 and the support frame 1. The top frame 11 adopts a nested design, with the lower part of the top frame 11 embedded in the internal cavity of the support frame 1. Medical staff can adjust the height of the top frame 11 in advance according to the patient's height, so that the patient can maintain a more comfortable standing and holding position. The limiting mechanism on the top frame 11 adopts a pin-type structure. When the top frame 11 is adjusted to the target height, the pin is inserted to form a rigid fixation between the top frame 11 and the support frame 1, preventing the top frame 11 from telescopically extending or retracting during use and ensuring the safety of assisted walking exercises. The pin-type limiting structure is a commonly used limiting structure in existing technology, and its specific structure and working principle will not be described in detail.

[0024] In addition, please see Figure 2 , Figure 4Two slides 24 are fixedly connected to the frame 22 in a mirror image. A support rod 25 is hinged to each slide 24. A support block 26 is fixedly connected to the end of the support rod 25 away from the slide 24. A contact block 28 is horizontally slidably connected to each slide 24. A first connecting rod 27 is hinged between the contact block 28 and the bottom of the support frame 1. A first leaf spring is provided between the support rod 25 and the slide 24. When the distance between the bottom of the support frame 1 and the frame 22 shortens, the support rod 25 can be swung downwards via the first connecting rod 27 and the contact block 28. Under normal circumstances, the force exerted by the patient's hands on the top frame 11 is mainly a pushing motion, and the patient's body weight is mainly supported by the legs. Therefore, the downward pressure exerted by the patient on the top frame 11 and the support frame 1 is relatively small, keeping the multiple first damping shock absorbers 21 in an extended state. When the patient experiences instability or leg weakness during assisted walking, causing the body to sag, the patient will use their arms to support their body, causing part of their body weight to press down on the top frame 11. The support frame 1 is subjected to pressure and moves towards the frame 22. Multiple first damping shock absorber rods 21 are compressed, causing the distance between the bottom of the support frame 1 and the frame 22 to shorten. This causes the bottom of the support frame 1 to pull the abutment block 28 to slide horizontally along the slide 24 via the first connecting rod 27. The sliding abutment block 28 will generate a thrust on the support rod 25, causing the support rod 25 to swing downward around its hinge point with the slide 24. Finally, the support block 26 contacts the ground and forms a support point. The support block 26 is made of non-slip material, which can provide additional friction and support after contacting the ground, effectively dispersing the force on the bottom of the frame 22, preventing the support frame 1 from tipping over or sliding, and facilitating the patient to adjust their center of gravity and recover leg strength. The first leaf spring is in a deformed state during the swing of the support rod 25. When the patient's center of gravity returns to stability and the distance between the support frame 1 and the frame 22 increases, the elastic restoring force of the first leaf spring will pull the support rod 25 to swing upward and reset, causing the support block 26 to leave the ground without affecting the normal movement of the device.

[0025] In addition, please see Figure 1 , Figure 5 , Figure 6A balancing assembly 3 is provided on the inner side of the support frame 1. The balancing assembly 3 includes two rocker arms 31. A support plate 32 is installed on the top of the rocker arms 31. The support plate 32 can move towards the patient and provide support when the patient's body tilts to the side. The two rocker arms 31 are hinged to the inner side of the support frame 1. Two portal frames 33 are fixedly installed on the support frame 1. Two pairs of second connecting rods 34 are hinged to the portal frames 33. The ends of the two pairs of second connecting rods 34 away from the portal frames 33 are hinged to a plate 35. Multiple first springs are provided between the plate 35 and the portal frames 33. A coil spring is provided at the hinge point between the rocker arms 31 and the support frame 1. The ends of the two rocker arms 31 away from the support plate 32 respectively abut against the two plates 35. The two plates 35 and the two support plates 32 are mirror images of each other. The rocker arms 31 always keep their bottom ends against the plate 35 by utilizing the elastic force of the coil springs. The portal frames 33 provide a stable mounting base for the second connecting rods 34 and the plate 35. The two pairs of second connecting rods 34 form a parallelogram structure. To ensure the plate 35 remains horizontal during movement, the force of the plate 35 is evenly transmitted to the lever 31. When the patient is walking with assistance, the two plates 35 are located on either side of the patient's legs, and the two support plates 32 are located under the patient's armpits. When the patient's legs weaken and the body shows signs of tilting, the patient's legs will exert pressure on the plate 35 in the tilting direction. Therefore, when the plate 35 is pushed by the patient's legs, the plate 35 can push the bottom of the lever 31 to move away from the patient, thereby causing the lever 31 to rotate around its hinge point with the support frame 1. The lever 31 has a lever structure, so the top of the lever 31 can drive the support plate 32 to move closer to the patient. After the support plate 32 moves towards the patient, it can support the patient's torso under the armpits and prevent the body from tilting further. After the patient's body returns to an upright position, the coil spring drives the lever 31 to reset, so that the support plate 32 returns to its initial position, and multiple first springs drive the plate 35 to reset.

[0026] It is worth noting that, please refer to Figure 6 The support plate 32 can be adjusted in height by telescoping the top of the rocker arm 31. A limiting mechanism for fixing the height of the support plate 32 is provided between the support plate 32 and the rocker arm 31. Through the telescoping structure of the support plate 32 at the top of the rocker arm 31, the support plate 32 can be adjusted to a height that is flush with the part of the patient that needs support, so that the supporting force can be accurately applied to the key position to achieve the best balance assistance effect. The limiting mechanism of the support plate 32 and the rocker arm 31 is similar in principle to the limiting mechanism of the top frame 11 and is implemented by a pin-type structure. When the support plate 32 is adjusted to the target height, the limiting mechanism can firmly lock the relative position of the support plate 32 and the rocker arm 31 to prevent the support plate 32 from sliding down or shifting during the support process, ensuring the stability and reliability of the support, and further improving the applicability and safety of the device.

[0027] Based on the above embodiments, another embodiment of the present invention is as follows: Please see Figure 1 , Figure 7 , Figure 8 The support frame 1 is equipped with a seat assembly 4, which includes two rotating frames 41. A half-seat cushion 42 and a half-lumbar support 43 are fixedly connected to each of the two rotating frames 41. The two rotating frames 41 can be opened and closed manually by the patient. When closed, they form a complete seat cushion and lumbar support. Both rotating frames 41 are hinged to the support frame 1. Two sliding sleeves 48 are horizontally slidably connected to the support frame 1. A third connecting rod 47 is hinged between the two sliding sleeves 48 and the two rotating frames 41. A telescopic rod 49 is hinged to the sliding sleeve 48, and a handle 410 is fixedly connected to the top of the telescopic rod 49. Two slotted plates 411 are fixedly connected to the outer wall of the top frame 11. Movable slots are formed on the slotted plates 411. The two telescopic rods 49 are located within the movable slots of the two slotted plates 411, and can extend and retract. The handle 410 is located above the slotted plates 411. During the sliding process of the telescopic rods 49 within the movable slots of the slotted plates 411, they can drive the sliding sleeves 48 towards the rotating frames 41. When the two sliding sleeves 48 move towards the rotating frame 41, they are driven to merge via the two third links 47. Normally, the two rotating frames 41 remain open and located on both sides of the support frame 1, not affecting the patient's entry and exit from the inside of the support frame 1. When the patient needs to rest, they can hold the handles 410 located on the outside of the top frame 11 with both hands. The telescopic rod 49 can adaptively extend and retract with the height of the top frame 11, keeping the handles 410 on the telescopic rod 49 always resting on the groove plate 411. The patient pulls the two handles 410 to move the telescopic rod 49 towards the rotating frame 41 within the movable groove of the groove plate 411. Simultaneously, the telescopic rod 49 drives the sliding sleeves 48 to move along the support frame 1 towards the rotating frame 41. As the sliding sleeves 48 move, they push the rotating frame 41 to rotate via the third link 47, causing the two rotating frames 41 to move closer to each other. Ultimately, the half-seat cushions 42 on the two rotating frames 41 merge to form a complete seat cushion, and the half-lumbar support 43 merges to form a complete lumbar support (e.g., Figure 11As shown, the support frame 4 provides dual support for the patient's hips and lower back, facilitating rest. Even after standing, the patient can continue moving. The two rotating frames 41 enclose the patient's back, providing some protection without hindering movement within the support frame 1. Similarly, pushing the two handles 410 in the opposite direction will cause the two sliding sleeves 48 to pull the two third connecting rods 47, opening the two rotating frames 41. When the patient needs to rest during assisted walking, they must first move to the seat, then exit the support frame 1, and then move to the seat. To stand up, they must re-enter the support frame 1. For patients with mobility issues, moving to the seat for rest is difficult and carries a risk of falling. However, the seat assembly 4 allows the patient to pull the two handles 410 to merge the two rotating frames 41, forming a complete seat and lumbar support behind them, providing support for rest at any time. The patient can simply sit back on the seat when needed.

[0028] It is worth noting that, please refer to Figure 9 , Figure 10 The movable groove of the slot plate 411 is divided into a sliding groove and two limiting grooves. The sliding groove is located between the two limiting grooves. A limiting rod 412 is horizontally slidably connected to the slot plate 411. A lever is provided at the top of the limiting rod 412. The limiting rod 412 can block one of the limiting grooves of the slot plate 411 by sliding. When the limiting rod 412 blocks the limiting groove, it can lock the telescopic rod 49 in the limiting groove. When the two rotating frames 41 are open, the telescopic rod 49 is located in the limiting groove of the rotating frame 41. When pulling the telescopic rod 49, it is necessary to first laterally push the telescopic rod 49 to slide it from the limiting groove to the limiting groove. In the sliding groove, the telescopic rod 49 is then pulled towards the rotating frame 41. After being pulled into place, the telescopic rod 49 is moved laterally so that it is embedded in the limiting groove near the rotating frame 41. The limiting groove limits the telescopic rod 49, thereby limiting the sliding sleeve 48, the third connecting rod 47, and the rotating frame 41, preventing the two rotating frames 41 from shaking when the patient is resting or walking, thus ensuring the stability of the seat assembly 4. When the telescopic rod 49 is in one of the limiting grooves, the limiting rod 412 is moved by the lever so that the limiting rod 412 locks the telescopic rod 49 in the limiting groove (e.g., Figure 9 As shown), the telescopic rod 49 is locked, thereby ensuring the stability of the two rotating frames 41. When the two rotating frames 41 are combined, the telescopic rod 49 is limited by the limiting rod 412. At this time, the two rotating frames 41 and the seat cushion and lumbar support above them are also kept in the combined state. At this time, the patient can still maintain the combined state of the seat cushion and lumbar support by releasing the two handles 410. At the same time, the patient can hold the two handles 410 to facilitate pushing the support frame 1 to move.

[0029] It is worth mentioning that you should refer to Figure 7 , Figure 8 A right-angle rod 44 is fixedly installed at the bottom of the rotating frame 41. A second damping shock absorber rod 45 is fixedly connected to the bottom end of the right-angle rod 44. A second universal wheel 46 is installed at the bottom end of the second damping shock absorber rod 45. The right-angle rod 44, the second damping shock absorber rod 45, and the second universal wheel 46 form a support structure to ensure the stability of the support frame 1 after the patient sits down and prevent it from tipping over. The pressure generated by the patient sitting down will be transmitted to the right-angle rod 44 at the bottom through the rotating frame 41. The function of the second damping shock absorber rod 45 is the same as the first damping in the action component 2. Similar to the shock absorber 21, its internal damping structure can buffer the impact force when the patient sits down, reducing the stimulation of vibration on the patient's waist and buttocks. After the patient sits down, the patient's body weight is transmitted to the support frame 1 and the frame 22 through the two rotating frames 41, triggering the two support blocks 26 to move down, thereby maintaining the stability of the frame 22 when the patient is resting. The second universal wheel 46 has a steering function. The two second universal wheels 46 and the four first universal wheels 23 together form six support points, which greatly improves the stability of the support frame 1.

[0030] Based on the above embodiments, another embodiment of the present invention is as follows: Please see Figure 1 , Figure 7 , Figure 11 - Figure 13The right-angle rod 44 is equipped with an anti-recoil mechanism 5, which includes a slider 51, a slide rod 53, and a wheel frame 55. The slider 51 is horizontally slidably connected to the top of the right-angle rod 44, and a second spring is provided between the slider 51 and the top of the right-angle rod 44. The slide rod 53 is vertically slidably connected to the side wall of the right-angle rod 44, and a fourth connecting rod 52 is hinged between the slide rod 53 and the slider 51. The wheel frame 55 is hinged to the top of the second damping shock absorber rod 45, and the top of the second damping shock absorber rod 45 is a fixed area that will not displace relative to the right-angle rod 44. A one-way roller 56 is rotatably mounted on the wheel frame 55. A lever 54 is connected to the slide rod 53, and a slot is provided on the wheel frame 55. The lever 54 is slidably connected to the slot of the wheel frame 55. The slider 51 protrudes from the top of the right-angle rod 44, and the two sliders 51 can... When the two sliders 51 come into contact and press against each other, they drive the slide bar 53 downward through the fourth link 52. The downward movement of the pivot shaft 54 ​​can drive the wheel frame 55 to swing downward through the slot. During the process of the rotating frame 41 merging and driving the right-angle rods 44 to approach each other, the sliders 51 protruding from the top of the two right-angle rods 44 will first come into contact and press against each other. The second spring between the slider 51 and the right-angle rod 44 is compressed. The horizontal movement of the slider 51 will be converted into an angle change of the fourth link 52, so that the fourth link 52 pushes the slide bar 53 downward along the side wall of the right-angle rod 44. When the slide bar 53 moves downward, it drives the pivot shaft 54 ​​to move downward. When the pivot shaft 54 ​​moves downward, it applies downward pressure to the inner wall of the slot of the wheel frame 55, thereby driving the wheel frame 55 to swing downward. Finally, the one-way roller 56 on the wheel frame 55 contacts the ground and forms a support (such as...). Figure 11 As shown), the surface of the one-way roller 56 is equipped with anti-slip strips, and its internal structure adopts a ratchet and pawl one-way braking structure, which only allows the one-way roller 56 to roll forward. When the support frame 1 moves forward, the two one-way rollers 56 roll along the ground. When the wheel frame 55 is pushed backward, the internal braking structure of the one-way roller 56 will lock immediately, so that the one-way roller 56 forms a friction surface with the ground through the anti-slip strips on its surface, achieving a parking effect. In this state, the support frame 1 can only move forward and cannot move backward, to prevent the support frame 1 from moving backward when the patient is resting or moving, which could cause the patient to lose balance and fall backward. When the two rotating frames 41 open, the opening of the rotating frames 41 drives the right-angle rod 44 to separate, the slider 51 loses the squeezing force, and the elastic force of the second spring pushes the slider 51 to reset, so that the slider 51 pulls the slide rod 53 upward through the fourth connecting rod 52, and the pivot 54 drives the wheel frame 55 to swing upward, so that the one-way roller 56 is lifted off the ground (as shown). Figure 7 As shown), the anti-reverse function is automatically deactivated, without affecting the normal steering and movement of the device.
