Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable standing training aid for patients with spinal cord injury. Background Technology

[0002] Spinal cord injuries are mostly caused by external trauma to the spine, resulting in sensory and motor dysfunction in the lower body and legs. Active and effective training to promote rehabilitation and help patients regain normal limb sensation and motor function is essential. Clinical treatment methods generally involve exercise training combined with medication and electrical stimulation.

[0003] Chinese patent document CN118001098A discloses a standing bed training device for the rehabilitation of patients with spinal cord injury. The bed frame is connected to a base via a horizontal pivot. The bed frame accommodates the patient lying flat and is equipped with an auxiliary training mechanism. The base is equipped with an angle adjustment mechanism that is driven and connected to the bed frame. A controller is connected to both the auxiliary training mechanism and the angle adjustment mechanism. The controller is configured to control the auxiliary training mechanism to perform spinal and leg movement training for the patient, and to control the angle adjustment mechanism during the training process to achieve dynamic angle adjustment of the bed frame from the horizontal to the vertical direction, thereby dynamically adjusting the load on the spine. During the patient's rehabilitation training, spinal and leg movement training are performed simultaneously, and the spinal load is gradually increased or decreased during the training process, avoiding secondary injury caused by a sudden increase in spinal load and improving the rehabilitation effect of the patient with spinal cord injury.

[0004] The existing technology has the following problems:

[0005] The training device directly fixes the patient to the upper side of the entire bed, and then rotates the rotating mechanism to make the patient stand upright. However, this form causes the patient to stand passively, making it difficult for various parts of their body to move, resulting in a low training effect. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, an adjustable standing training assistive device for patients with spinal cord injury includes a platform 1. A first rotating plate 2 is rotatably connected to the inner front and rear sides of the platform 1 near the upper left side. A second rotating plate 3 is slidably connected to the upper side of the first rotating plate 2. A lifting mechanism 4 is movably installed on the lower side of the first rotating plate 2 and the second rotating plate 3. A buffer mechanism 5 is fixedly connected to the front and rear sides of the platform 1 near the left side. A support mechanism 6 is fixedly connected to the front and rear sides of the platform 1 near the left side.

[0028] The support mechanism 6 includes a first electric cylinder 61. The outer side of the first electric cylinder 61 is fixedly connected to the front and rear sides of the mechanism platform 1 near the left side. There are two first electric cylinders 61 distributed in the front and rear. The lower ends of the two first electric cylinders 61 are fixedly connected to a movable frame 62. The middle left side of the two movable frames 62 is fixedly connected to a rotating shaft 63. The outer side of the rotating shaft 63 is rotatably connected to a first support assembly 64. A second support assembly 65 is movably installed on the upper side of the movable frame 62.

[0029] It should be noted that the patient lies on the first rotating platform 2 and the second rotating platform 3. Both the first rotating platform 2 and the second rotating platform 3 can be secured with straps to keep the patient in close contact with the first rotating platform 2 and the second rotating platform 3. The patient's buttocks are placed on the first rotating platform 2. The lifting mechanism 4 first drives the second rotating platform 3 to rotate, so that the patient is in a sitting position. Then it drives the first rotating platform 2 and the second rotating platform 3 to rotate, so that the patient slowly stands up. During this process, the patient is stabilized by the second support component 65. The first electric cylinder 61 drives the moving frame 62 to move up and down, thereby adjusting the position of the second support component 65.

[0030] like Figure 3 , Figure 4 As shown, the buffer mechanism 5 includes a mechanism frame 51. The front and rear sides of the mechanism frame 51 are fixedly connected to the inner front and rear sides of the mechanism platform 1 near the left side. Two sliding frames 52 distributed in the front and rear are slidably connected to the outer side of the mechanism frame 51. Support components 55 are slidably connected to the outer side of each of the two sliding frames 52. Several first adjustment holes 53 distributed in the front and rear are opened on the left side of the mechanism frame 51. Several second adjustment holes 54 distributed in the upper and lower are opened on the front and rear sides of each of the two sliding frames 52.

[0031] It should be noted that the first adjustment hole 53 and the second adjustment hole 54 are fixed to the sliding frame 52 and the support component 55 respectively by screws, so that the position of the support component 55 can be adjusted to adapt to different leg spacing and different foot heights of different patients.

[0032] like Figure 4 As shown, the support assembly 55 includes a base 551. The right side of the base 551 is slidably connected to the outside of the sliding frame 52. Four rectangularly distributed limiting rods 552 are movably sleeved on the inner side of the base 551 near the four corners. A pedal 553 is fixedly connected to the upper side of the limiting rods 552. Springs 554 are movably sleeved on the outer side of each of the four limiting rods 552, and the springs 554 are located on the upper side of the base 551.

[0033] It should be noted that the patient's feet are fixed to the footplate 553 with straps. When the patient is assisted to stand, the footplate 553 supports the patient's feet. When the patient's feet are unstable, the spring 554 cushions the impact to prevent the patient's feet from being subjected to a sudden downward impact from the upper side due to instability when they are on the fixed surface.

[0034] like Figure 4 As shown, a threaded sleeve 555 is rotatably connected to the upper middle part of the base 551, an adjusting plate 558 is threadedly connected to the outer side of the threaded sleeve 555, and a spring 554 is located on the upper side of the adjusting plate 558. A transmission rod 556 is rotatably connected to the inner side of the pedal 553, and the outer side of the transmission rod 556 is movably sleeved on the inner side of the threaded sleeve 555.

[0035] It should be noted that rotating the transmission rod 556 causes the threaded sleeve 555 to rotate. When the threaded sleeve 555 rotates, the adjusting plate 558 moves up and down. When the adjusting plate 558 moves up and down, the initial compression of the spring 554 is adjusted.

[0036] like Figure 4 As shown, a rubber sheet 557 is fixedly connected to the inner side of the upper groove of the pedal 553 near the left side, and the rubber sheet 557 is located on the upper side of the transmission rod 556.

[0037] It should be noted that the rubber sheet 557 is used to seal the upper side of the transmission rod 556 to prevent the holes on the upper side of the transmission rod 556 used for connecting handles and other transmission components from being exposed.

[0038] like Figure 5 , Figure 6 As shown, the first support assembly 64 includes a rotating plate 641. The rear side of the rotating plate 641 is rotatably connected to the outside of the rotating shaft 63 located at the rear side. A retaining sleeve 642 is fixedly connected to the front side of the rotating plate 641. The inner side of the retaining sleeve 642 is movably sleeved on the outside of the rotating shaft 63 located at the front side. A limiting plate 643 is rotatably connected to the upper side of the rotating shaft 63 near the right side, and the limiting plate 643 is located on the upper side of the retaining sleeve 642. A retaining seat 644 is fixedly connected to the upper side of the rotating shaft 63 near the right side, and the limiting plate 643 is located on the inner side of the retaining seat 644.

[0039] It should be noted that a torsion spring is provided between the limiting plate 643 and the rotating shaft 63 to stabilize the state of the limiting plate 643, so that the limiting plate 643 fixes the sleeve 642. Rotating the limiting plate 643 will cause the limiting plate 643 to no longer restrict the sleeve 642, thereby preventing the first support component 64 from obstructing the patient from lying on the first rotating plate 2. The second support component 65 contains the same parts and structure as the first support component 64. The difference is that the rotating plate 641 on the second support component 65 is replaced with a round rod, and it also does not contain the second electric cylinder 645 and the push plate 646.

[0040] like Figure 5 , Figure 6 As shown, two second electric cylinders 645 are fixedly connected to the left side of the rotating plate 641, and a push plate 646 is fixedly connected to the right side of the second electric cylinders 645, with the push plate 646 located on the right side of the rotating plate 641.

[0041] It should be noted that the second electric cylinder 645 can push the push plate 646 to move, thereby pushing the patient's legs to help the patient stand up.

[0042] The working principle of this utility model is as follows: First, the patient lies on the first rotating plate 2 and the second rotating plate 3. Both the first and second rotating plates 2 and 3 can be secured with straps to keep the patient in close contact with them. The patient's buttocks are placed on the first rotating plate 2. The lifting mechanism 4 first rotates the second rotating plate 3, putting the patient in a sitting position. Then, it rotates the first and second rotating plates 2 and 3, allowing the patient to slowly stand up. During this process, the patient is stabilized by the second support component 65. The first electric cylinder 61 moves the moving frame 62 up and down, thereby adjusting the position of the second support component 65. A torsion spring is provided between the limiting plate 643 and the rotating shaft 63 to stabilize the state of the limiting plate 643. The limiting plate 643 fixes the sleeve 642. Rotating the limiting plate 643 removes the sleeve 642 from the limiting plate, thus preventing the first support assembly 64 from obstructing the patient from lying on the first rotating plate 2. The second support assembly 65 contains the same parts and structure as the first support assembly 64, except that the rotating plate 641 on the second support assembly 65 is replaced by a round rod. It also does not contain the second electric cylinder 645 and the push plate 646. The second electric cylinder 645 can push the push plate 646 to move, thereby pushing the patient's legs and assisting the patient to stand. The lifting mechanism 4 drives one side of the first rotating plate 2 and the second rotating plate 3 to rise and fall, causing them to rotate, thereby pushing the patient to stand. In a standing position, the patient stands using the first support component 64 and the second support component 65. Since the patient's body is not restricted, they can stabilize themselves using their own strength, achieving the purpose of exercise. Finally, the first adjustment hole 53 and the second adjustment hole 54 are fixed to the sliding frame 52 and the support component 55 respectively using screws, thereby allowing the position of the support component 55 to be adjusted to accommodate different leg spacing and foot heights of different patients. The patient's feet are fixed to the footrest 553 with straps. When the patient is assisted in standing, the footrest 553 supports the patient's feet. When the patient's feet are unstable, the spring 554 cushions the impact, preventing the patient from becoming unstable. When the foot is on the fixed surface, it is subjected to a momentary downward impact from the upper side due to instability. The transmission rod 556 is rotated, which in turn causes the threaded sleeve 555 to rotate. When the threaded sleeve 555 rotates, the adjusting plate 558 moves up and down. When the adjusting plate 558 moves up and down, the initial compression of the spring 554 is adjusted. The position of the support component 55 is adjusted through the second adjusting hole 54 and the first adjusting hole 53. Then, the patient steps on the pedal 553, so that when the device assists the patient to stand, it will not cause the patient's feet to be unstable due to not being in a restricted state, and the fixed foot placement surface will not cause impact to the patient. At the same time, the patient can lift his feet slightly for exercise.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
