Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a walking suspension device for rehabilitation. Background Technology

[0002] Injuries to the feet, legs, or nerves can restrict mobility, requiring rehabilitation and exercise after treatment to restore mobility. This necessitates a rehabilitation walking suspension device, typically consisting of a support frame, slide rails, sliders, and a suspension unit. Before use, the patient wears a suspension garment with hooks connecting to the suspension unit. During walking, the suspension unit bears most of the patient's weight, reducing the load on the feet and legs. While this type of rehabilitation walking suspension device is simple and stable, it has limitations in practical use. The single-slide rail structure places the entire weight of the patient and the device on the rail, potentially causing metal fatigue and reducing its lifespan. This application proposes a rehabilitation walking suspension device to address these issues. Summary of the Invention

[0003] This application proposes a walking suspension device for rehabilitation, which has the advantage of more convenient suspension height adjustment, in order to solve the problem of difficulty in adjustment after the patient wears a suspension garment.

[0004] To achieve the above objectives, this application adopts the following technical solution: a rehabilitation walking suspension device, including two footboards respectively arranged on the left and right sides, a pad fixedly installed at the bottom of the footboard, and a cross-shaped support steel structure fixedly installed at the top of the footboard near both ends, in order to improve the support strength.

[0005] Specifically, the top is fixedly installed with a mounting base, a limiting crossbar is fixedly installed on one side of the mounting base, an adjustment device is movably installed inside, a support device is movably installed at one end of the adjustment device, a sliding device is movably installed inside the support device, and the limiting crossbar cooperates with the sliding device to limit the sliding posture of the sliding device.

[0006] Furthermore, the device includes a limiting slide, and the top and bottom of the inner side of the limiting slide are provided with limiting protrusions. The limiting protrusions cooperate with the mounting base, and the mounting base is limited by the limiting protrusions during movement.

[0007] Specifically, a servo motor is fixedly installed at the middle position of the bottom inner side of the limiting slide. An adjusting screw is fixedly installed at one end of the output shaft of the servo motor. The adjusting screw extends through the limiting slide to the outside. The outer surface of the adjusting screw is threaded onto the mounting base. When the servo motor drives the adjusting screw to rotate, it will drive the mounting base to move along the axis of the adjusting screw.

[0008] Specifically, the bottom inner side of the limiting slide is provided with strip-shaped holes located on both sides of the servo motor.

[0009] Furthermore, the adjusting device includes an adjusting plate with a threaded hole on one side that engages with an adjusting screw. Push plates are movably fitted at both ends of the adjusting plate, passing through a strip-shaped hole and entering the interior of a limiting slide. A first slider is movably fitted at one end of the push plate, with mating grooves at its top and bottom. The first slider is movably installed inside the limiting slide, with the mating grooves engaging with a limiting protrusion. During the rotation of the adjusting screw, the adjusting plate is driven to move along the axis of the adjusting screw via the thread, thereby causing the first slider to move along the extension direction of the limiting protrusion under the pushing action of the push plate.

[0010] Specifically, a rotating rod is movably sleeved on the front of the first slider, and a matching rod is fixedly installed on the outer surface of the rotating rod near the middle position. The matching rod is movably installed with the support device, and the angle of the support device will be adjusted during the movement of the first slider.

[0011] Furthermore, the support device includes a main beam, with side plates fixedly installed on the front of the main beam near both ends. A mating seat is fixedly installed on the top of the side plate near one end. A mating hole is opened on the front of the mating seat, and the mating hole is fitted with a mating rod. An upper support plate and a lower support plate are fixedly installed on the top and bottom of the back of the main beam, respectively. The upper support plate and the lower support plate support the sliding device.

[0012] Specifically, anti-detachment protrusions are fixedly installed on the bottom of the upper support plate and the top of the lower support plate near the outer side. The anti-detachment protrusions limit the sliding device and prevent it from falling off.

[0013] Specifically, the top of the upper support plate is provided with a sliding groove, which works in conjunction with the sliding device to limit movement.

[0014] Furthermore, the sliding device includes a sliding seat, with guide wheels provided on the top and bottom near both sides of the sliding seat. A limiting seat is fixedly installed on the top of the sliding seat near the center, and the limiting seat cooperates with the sliding groove. A connecting shaft is sleeved on the top of the limiting seat near the center, and a rotating connecting plate is fixedly installed on the top of the connecting shaft. A telescopic rod is fixedly installed on one side of the rotating connecting plate. A telescopic bushing is movably sleeved on the outer surface of the telescopic rod. A second slider is fixedly installed on the top of the outer surface of the telescopic bushing. A sliding hole is opened on the front of the second slider, and the sliding hole is movably sleeved with the limiting crossbar. A lifting lug is fixedly installed on the front of the sliding seat, and a lifting strap is sleeved on the outer surface of the lifting lug. A lifting strap is fixedly sleeved at the bottom of the lifting strap.

[0015] This application has the following beneficial effects.

[0016] This device offers better load-bearing capacity, a longer lifespan, and adjustable height to suit different patient heights. The adjustment process is convenient and does not require the patient to put on or take off the suspension garment. Furthermore, the device can be set to continuously increase the load on the patient's feet and legs as they walk, allowing for more targeted rehabilitation methods tailored to each patient's specific needs.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Please refer to a rehabilitation walking suspension device. Figure 1 It includes a tripod 1, there are two tripods 1 and they are respectively set on the left and right sides. A pad 2 is fixedly installed at the bottom of the tripod 1. A support frame 3 is fixedly installed at the top of the tripod 1 near both ends. A cross-shaped support steel structure is fixed between the support frames 3 to improve the support strength of the support frames 3.

[0022] Please see Figure 1 A limiting device 4 is fixedly installed on the top of the support frame 3. A mounting base 5 is fixedly installed on the top of the limiting device 4. A limiting crossbar 6 is fixedly installed on one side of the mounting base 5. An adjusting device 7 is movably installed inside the limiting device 4. A supporting device 8 is movably installed at one end of the adjusting device 7. A sliding device 9 is movably installed inside the supporting device 8. The limiting crossbar 6 cooperates with the sliding device 9 and restricts the posture of the sliding device 9 during sliding.

[0023] During use, the patient's weight is borne by two support devices 8 and a limiting crossbar 6, which reduces the load on each individual support device 8 and limiting crossbar 6, thereby extending the device's service life. In contrast, traditional devices are composed of a single slide rail that bears the patient's weight, making them more prone to metal fatigue and reducing their service life. This application effectively avoids this problem and improves the device's reliability.

[0024] Please seeFigures 1-3 The limiting device 4 includes a limiting slide 41. The top and bottom of the inner side of the limiting slide 41 are provided with limiting protrusions 42. The limiting protrusions 42 cooperate with the mounting base 5. The mounting base 5 is limited by the limiting protrusions 42 during movement.

[0025] Please see Figures 1-3 A servo motor 43 is fixedly installed at the middle position of the bottom inner side of the limiting slide 41. An adjusting screw 44 is fixedly installed at one end of the output shaft of the servo motor 43. The adjusting screw 44 extends through the limiting slide 41 to the outside. The outer surface of the adjusting screw 44 is threaded to the mounting seat 5. When the servo motor 43 drives the adjusting screw 44 to rotate, it will drive the mounting seat 5 to move along the axis of the adjusting screw 44.

[0026] Please see Figure 3 A strip hole 45 is provided on the bottom inner side of the limiting slide 41, located on both sides of the servo motor 43.

[0027] Patients or medical personnel can adjust the two servo motors 43 to different degrees, so that the two support devices 8 are not parallel and have an angle. At this time, the patient can start walking from the end with the larger gap between the support devices 8. During this process, the gap between the support devices 8 continuously decreases and the height of 903 continuously decreases, so that the traction force of the device on the suspension garment worn by the patient continuously decreases and the load on the patient's feet and legs continuously increases. The patient needs to exert more effort to complete the walking movement, so that the device can carry out more targeted rehabilitation according to the patient's specific condition, further improving the practicality of the device.

[0028] Please see Figures 2-4 The adjusting device 7 includes an adjusting plate 71. A threaded hole is provided on one side of the adjusting plate 71, and the threaded hole cooperates with the adjusting screw 44. Push plates 72 are movably sleeved at both ends of the adjusting plate 71. The push plates 72 pass through the strip hole 45 and enter the interior of the limiting slide 41. A first slider 73 is movably sleeved at one end of the push plate 72. The top and bottom of the first slider 73 are provided with mating grooves 74. The first slider 73 is movably installed inside the limiting slide 41, and the mating grooves 74 cooperate with the limiting protrusion 42. During the rotation of the adjusting screw 44, the adjusting plate 71 is driven to move along the axis of the adjusting screw 44 through the thread. Thus, under the pushing action of the push plates 72, the first slider 73 is driven to move along the extension direction of the limiting protrusion 42.

[0029] Please see Figure 1 and Figure 4The first slider 73 is movably fitted with a rotating rod 75 on its front side. A matching rod 76 is fixedly installed on the outer surface of the rotating rod 75 near the middle position. The matching rod 76 is movably installed with the support device 8. During the movement of the first slider 73, the angle of the support device 8 will be adjusted.

[0030] Please see Figure 1 and Figures 4-6 The support device 8 includes a main beam 81. Side plates 82 are fixedly installed on the front of the main beam 81 near both ends. A mating seat 83 is fixedly installed on the top of the side plate 82 near one end. A mating hole 84 is opened on the front of the mating seat 83. The mating hole 84 is sleeved with the mating rod 76. An upper support plate 85 and a lower support plate 86 are fixedly installed on the top and bottom of the back of the main beam 81, respectively. The upper support plate 85 and the lower support plate 86 provide support for the sliding device 9.

[0031] Please see Figure 1 and Figures 5-6 Anti-detachment protrusions 87 are fixedly installed on the bottom of the upper support plate 85 and the top of the lower support plate 86 near the outer side. The anti-detachment protrusions 87 limit the sliding device 9 to prevent it from falling off.

[0032] Please see Figure 1 and Figures 5-6 The top of the upper support plate 85 is provided with a sliding groove 88, which works in conjunction with the sliding device 9 to limit movement.

[0033] When the hook on the patient's outer suspension garment is fixedly connected to the bottom of 903, if the height is not suitable, the patient can directly adjust the distance between the main beams 81 by controlling the adjusting screw 44 and the servo motor 43, thereby adjusting the height. There is no need to take off the suspension garment for adjustment, which reduces the difficulty of using the device and improves its practicality.

[0034] Please see Figure 1 and Figures 5-8The sliding device 9 includes a sliding seat 91. Guide wheels 92 are provided on the top and bottom of the sliding seat 91 near both sides. A limiting seat 93 is fixedly installed on the top of the sliding seat 91 near the middle. The limiting seat 93 cooperates with the sliding groove 88. A connecting shaft 94 is sleeved on the top of the limiting seat 93 near the middle. A rotating connecting plate 95 is fixedly installed on the top of the connecting shaft 94. A telescopic rod 96 is fixedly installed on one side of the rotating connecting plate 95. A telescopic bushing 97 is movably sleeved on the outer surface of the telescopic rod 96. A second slider 98 is fixedly installed on the top of the outer surface of the telescopic bushing 97. A sliding hole 99 is opened on the front of the second slider 98. The sliding hole 99 is movably sleeved with the limiting crossbar 6. A lifting lug 901 is fixedly installed on the front of the sliding seat 91. A sling 902 is sleeved on the outer surface of the lifting lug 901. A 903 is fixedly sleeved on the bottom of the sling 902. The 903 is connected to a suspension garment worn by the patient with hooks.

[0035] The user can control the servo motor 43 to drive the adjusting screw 44 to rotate. Under the action of the threaded engagement, the adjusting screw 44 drives the adjusting plate 71 to move along the axis of the adjusting screw 44. Driven by the push plate 72, the first slider 73 moves laterally inside the limiting slide 41. When the patient is tall, the adjusting plate 71 can be controlled to move closer to the limiting device 4. At this time, the first sliders 73 move away from each other, which increases the distance between the supporting devices 8. During this process, the top of the sling 902 moves to both sides and drives 903 to move upward, making... The sling 903 can be adapted to the patient's height. Similarly, when the patient is shorter, the height of 903 can be lowered by performing the opposite operation, ensuring that the device can be adapted to patients of different heights. In addition, the patient can adjust the weight borne by the feet and legs through the above operation, thereby adjusting the height of the sling 902 according to the rehabilitation needs. The higher the height of the sling 902, the greater the weight borne by the patient's feet and legs, and the lower the height of the sling 902, the less the weight borne by the patient's feet and legs, thus improving the practicality of the device.

[0036] By using the limiting crossbar 6 in conjunction with the sliding hole 99, the sliding device 9 can keep the telescopic sleeve 97 parallel to the limiting device 4 as it moves with the patient. This ensures that the two sliding seats 91 remain in the same lateral position as the sliding device 9 moves with the patient, preventing excessive movement of one side of the sliding seat 91 that could cause the 903 to deflect and potentially lead to the patient falling. This improves the safety performance of the device.

[0037] The method of using this invention is as follows: Before use, the user can control the servo motor 43 to drive the adjusting screw 44 to rotate. Under the action of the threaded engagement, the adjusting screw 44 drives the adjusting plate 71 to move along the axis of the adjusting screw 44. Driven by the push plate 72, the first slider 73 moves laterally inside the limiting slide 41. When the patient is tall, the adjusting plate 71 can be controlled to move closer to the limiting device 4. At this time, the first sliders 73 move away from each other, which increases the distance between the supporting devices 8. During this process, the top of the sling 902 moves to both sides and drives 903 to move upward, so that 903 can be adapted to the patient's height. Similarly, when the patient is short, the opposite operation can be used to lower 903. The height is designed to ensure the device can be adapted to patients of different heights. In addition, patients can adjust the weight borne by their feet and legs through the above operation, thereby adjusting the height of the sling 902 according to rehabilitation needs. The higher the height of the sling 902, the greater the weight borne by the patient's feet and legs; the lower the height of the sling 902, the less the weight borne by the patient's feet and legs. When the hook on the suspension garment worn by the patient is fixedly connected to the bottom of 903, if the height is not suitable, the patient can directly adjust the distance between the main beams 81 by controlling the adjusting screw 44 and the servo motor 43, thereby adjusting the height without having to remove the suspension garment for adjustment.

[0038] Patients or medical personnel can adjust the two servo motors 43 to different degrees, so that the two support devices 8 are not parallel and have an angle. At this time, the patient can start walking from the end with the larger gap between the support devices 8. During this process, the gap between the support devices 8 continuously decreases and the height of 903 continuously decreases, so that the traction force of the device on the suspension garment worn by the patient continuously decreases and the load on the patient's feet and legs continuously increases. The patient needs to exert more effort to complete the walking movement, so that the device can provide more targeted rehabilitation according to the patient's specific situation. Through the cooperation of the limiting crossbar 6 and the sliding hole 99, the sliding device 9 can always keep the telescopic sleeve 97 parallel to the limiting device 4 during the movement of the patient. Thus, during the movement of the sliding device 9 with the patient, the two sliding seats 91 can always remain in the corresponding lateral positions.
