Description

Technical Field

[0001] The invention relates to the technical field of human rehabilitation training, and in particular to a human pre-adaptation anti-fall rehabilitation training device. Background Art

[0002] Rehabilitation training stairs are a type of equipment designed specifically for lower limb rehabilitation training and are commonly used in physical therapy and rehabilitation centers.

[0003] When patients use rehabilitation training stairs for rehabilitation training, the patients' strides vary greatly due to different degrees of recovery of their lower limb injuries. In the case of a small stride, if the steps of the rehabilitation training stairs are too wide, the patients cannot directly step onto the next step, but need to move forward a distance on the standing step before stepping onto the next step, which makes the rehabilitation training stairs inconvenient to use.

[0004] At the same time, if the patient falls forward on the steps, the patient's knees are very likely to hit the positive corner of the steps. The existing technology usually achieves cushioning for the patient's knees by installing sponge pads on the positive corners. However, the sponge pads are used for too long and harden. The cushioning effect of the sponge pads on the patient's knees will be reduced, resulting in the patient's knees being injured due to insufficient cushioning, affecting the patient's life safety. Summary of the invention

[0005] In order to overcome the disadvantages that when the patient has a small stride, the patient cannot directly step onto the next step, resulting in inconvenience in using the rehabilitation training stairs; at the same time, if the patient's knee hits the positive corner of the step and the sponge pad is used for too long, it will harden and the patient's knee will be injured due to insufficient cushioning, affecting the patient's life safety, the present invention provides a human body pre-adaptive anti-fall rehabilitation training device.

[0032] The power unit includes a slide rail 102 and an electric slider 103 ; each of the two supporting plates 101 is fixedly connected to a slide rail 102 on the opposite sides; each slide rail 102 is slidably connected to a plurality of electric sliders 103 ; each electric slider 103 is fixedly connected to an adjacent connecting frame 104 .

[0033] The buffer assembly includes a connecting plate 105, an elastic member 106, an extrusion plate 107 and a visual buffer unit; a connecting plate 105 is connected to the upper side of each connecting frame 104; each connecting plate 105 is rotatably connected to the adjacent limit plate 4 through a torsion spring; an engaging groove is provided on each connecting plate 105; a plurality of elastic members 106 are fixedly connected in the engaging groove on each connecting plate 105, and the elastic member 106 is a spring; the other end of the elastic member 106 located in the same engaging groove is commonly fixedly connected to an extrusion plate 107; a visual buffer unit is connected to the rehabilitation training staircase 1.

[0034] The visual buffer unit includes a sponge pad 108 and a visual sensor 110; each extrusion plate 107 is rotationally connected to the adjacent pedal 3 through a torsion spring; a sponge pad 108 is fixedly connected to the front side of each pedal 3; and a visual sensor 110 is fixedly connected to the armrest 2.

[0035] The support assembly includes a servo motor 201 and a support plate 202; a servo motor 201 is fixedly connected to the rear side of each connecting plate 105; a support plate 202 is fixedly connected to the output end of each servo motor 201; and the other end of each support plate 202 contacts the adjacent pedal 3.

[0036] The present invention enables the pedal 3 to slide forward and backward on the limit plate 4 to change the relative position between the pedal 3 and the limit plate 4, so that when the patient uses the rehabilitation training staircase 1 and steps on the pedal 3 and the limit plate 4, the distance between the patient stepping on the next pedal 3 and the limit plate 4 is increased or shortened, so that the patient's stride length is matched with the pedal 3 and the limit plate 4, and the problem of inconvenience in using the rehabilitation training staircase 1 is solved, that when the patient's stride length is small, the patient cannot directly step on the next pedal 3 and the limit plate 4, but needs to move forward a distance before stepping on the next pedal 3 and the limit plate 4. The specific working content is as follows:

[0037] The following is an explanation of the pedal 3 and the limit plate 4 located at the front side. First, before the patient uses the rehabilitation training staircase 1, the medical staff first tests the patient's stride. After the test, the medical staff controls the electric slider 103 to slide forward or backward along the slide rail 102 through the remote control, thereby driving the connecting frame 104, the connecting plate 105 and the elastic member 106 to move forward or backward, and then drives the extrusion plate 107, the sponge pad 108 and the pedal 3 to move, so that the pedal 3 slides on the limit plate 4, thereby adjusting the relative position between the pedal 3 and the limit plate 4 until it matches the patient's stride, stops the electric slider 103 from sliding, so that the pedal 3 stops sliding on the limit plate 4, and then controls the remaining electric sliders 103 to slide along the slide rail 102 through the remote control, thereby driving the remaining pedals 3 to move. The pedals 3 and the limit plates 4 are moved to the next step, and the relative positions of the remaining pedals 3 and the limit plates 4 are adjusted until the relative positions of all the pedals 3 and the limit plates 4 are adjusted. At this time, when the patient steps on the pedals 3 and the limit plates 4, the patient's feet are supported by the pedals 3 and the limit plates 4. When the patient's stride is small, it is prevented that the patient cannot directly step on the pedals 3 and the limit plates 4, but needs to move forward a certain distance before stepping on the pedals 3 and the limit plates 4, resulting in inconvenience in the use of the rehabilitation training stairs 1. When the patient's stride is large, it is prevented that the patient crosses the pedals 3 and the limit plates 4 and steps on the pedals 3 and the limit plates 4 of the next level, which makes the patient's movement change too drastic, which is not conducive to the patient's physical rehabilitation. Compared with the prior art, the convenience of using the rehabilitation training stairs 1 is improved, and the safety of patients using the rehabilitation training stairs 1 is improved.

[0038] Subsequently, when the patient uses the rehabilitation training stairs 1 for rehabilitation training, if the patient's legs cannot support the patient and the patient falls forward, the patient's knees are very likely to collide with the front end of the pedal 3, causing the patient's knees to be injured. At this time, the sponge pad 108 is used to initially cushion the patient's knees. At the same time, when the visual sensor 110 on the handrail 2 detects that the patient's body is falling forward quickly and significantly, the visual sensor 110 transmits a signal to control the servo motor 201 on the next-level connecting plate 105 where the patient is standing to start. Based on the view from right to left, the servo motor 201 drives the support plate 202 to rotate clockwise, so that the support plate 202 is separated from the pedal 3, so that the pedal 3 loses the support of the support plate 202, and then when the patient's knee hits the sponge pad 108, the impact force of the patient's knee hitting the sponge pad 108 will be transmitted to the squeezing plate 107, as shown in FIG. Figure 5 As shown, the elastic member 106 is compressed and the extrusion plate 107 moves downward. Looking from right to left, the torsion spring between the extrusion plate 107 and the pedal 3 is compressed, and the torsion spring between the limit plate 4 and the connecting plate 105 is compressed, so that the pedal 3 and the limit plate 4 rotate counterclockwise, so that the impact force of the patient's knee hitting the sponge pad 108 is absorbed by the elastic member 106, so that the elastic member 106 achieves secondary cushioning of the patient's knee, avoiding the patient's knee from being bumped and injured, thereby further improving the protection effect of the patient's knee.

[0039] Afterwards, the medical staff helps the patient up, and the patient's knees are separated from the sponge pad 108, so that the elastic member 106 returns to its original state, thereby moving the extrusion plate 107 upward, and the torsion spring between the extrusion plate 107 and the pedal 3 returns to its original state, and the torsion spring between the limit plate 4 and the connecting plate 105 returns to its original state, thereby driving the pedal 3 and restoring the limit plate 4 to their initial state. Then, depending on the patient's physical condition, the patient is selectively allowed to continue training or rest.

[0040] A protective cover made of sponge material is provided on the armrest 2, which is used to absorb the sweat on the palms of the patient during training, to prevent the sweat from causing the patient's hands to slip on the armrest 2, causing the patient to fall, and affecting the patient's personal safety.

[0041] It also includes sponge strips 109; a plurality of sponge strips 109 are fixedly connected to the upper surface of each pedal 3; when the patient steps on the pedal 3 and the limit plate 4, the sponge strips 109 increase the roughness of the surface of the pedal 3, thereby increasing the surface friction of the pedal 3, reducing the probability of the patient slipping on the pedal 3, thereby improving the safety of rehabilitation training.

[0042] Example 2

[0043] On the basis of Example 1, Figure 1 and Figure 6As shown, each pedal 3 is provided with a pressure sensor.

[0044] When the patient's two feet step on different pedals 3 and limit plates 4 respectively, the pressure sensor on the pedal 3 detects the pressure of the patient's two feet on the pedal 3. Subsequently, when the patient steps the back foot onto the pedal 3 and limit plate 4 where the front foot stands, the patient's back foot is lifted, and before stepping on the next pedal 3 and limit plate 4, the patient's back foot is in a suspended state, so that the patient's whole body weight is supported by the front foot. If the patient's front foot is not enough to support the whole body weight at this time, the patient's back foot must be withdrawn, so that the patient's back foot is placed back on the pedal 3 and limit plate 4 where the patient originally stood. Because the patient's front foot is unstable at this time, after the patient's back foot is put back to the above position, the patient is likely to fall backwards. Therefore, when the patient's back foot is lifted upward, the pressure sensor on the pedal 3 detects that the pressure on the pedal 3 disappears, and the pressure sensor on the pedal 3 transmits a signal to the servo motor 201, so that the servo motor 201 on the lower side of the pedal 3 and the limit plate 4 that controls the patient's standing when the back foot is lifted is started, and the servo motor 201 is used to rotate the support plate 202 counterclockwise to the position as shown in the figure. Figure 6 In the state shown in FIG. 1 , the support plate 202 squeezes the pedal 3 during the rotation process, stretching the elastic member 106, and the pedal 3 and the limit plate 4 rotate clockwise to the position shown in FIG. 1 . Figure 6 In the state shown, when the patient's back foot steps on the original pedal 3 and the limit plate 4 again (hereinafter referred to as "the original pedal 3 and the limit plate 4" as the original step), since the original step is inclined upward, therefore, when the patient's back foot contacts the original step, the support of the original step for the patient's back foot changes from the original vertical direction to the current inclined direction, thereby giving the patient's back foot a supporting force toward the front of the body, and when the patient's back foot steps on the original step, the patient is prevented from falling backwards, causing injury to the patient and affecting the patient's personal safety.

[0045] Example 3

[0046] On the basis of Examples 1 and 2, Figure 1-Figure 4 and Figure 7 As shown, the locking assembly includes an electric lock 301 and a fixed block 302; two electric locks 301 are fixedly connected to the rear side of each connecting frame 104; a fixed block 302 is fixedly connected to the rear side of each connecting plate 105; the lock core of each electric lock 301 cooperates with the adjacent fixed block 302; the connection between the connecting frame 104 and the connecting plate 105 is realized by the electric lock 301 and the fixed block 302.

[0047] The following is an explanation of the electric slider 103 at the front. When the patient needs to perform hill climbing rehabilitation training, the medical staff uses the remote control to pull out the lock cores of all the electric locks 301 from the fixed block 302, so that the electric lock 301 and the fixed block 302 are disengaged from each other, and then the connecting frame 104 and the connecting plate 105 are disengaged from each other. At the same time, based on the view from right to left, the servo motor 201 is controlled to drive the support plate 202 to rotate clockwise, so that the support plate 202 and the pedal 3 are disengaged from each other. Subsequently, the medical staff controls the electric slider 103 to slide forward along the slide rail 102 through the remote control, thereby driving the connecting plate 105, the elastic member 106 and the extrusion plate 107 to move forward. Since all the connecting frames 104 and the connecting plates 105 are disengaged from each other, therefore, driven by the electric slider 103, as shown in FIG. Figure 7 As shown, the torsion spring between the extrusion plate 107 and the pedal 3 will be compressed, and the extrusion plate 107 will rotate clockwise and the pedal 3 will rotate counterclockwise, so that the connection angle between the extrusion plate 107 and the pedal 3 changes from a right angle to a flat angle. When the electric slider 103 continues to slide forward, the angles between all the extrusion plates 107 and the pedal 3 will change to Figure 7 In the state shown, the rehabilitation training stairs 1 is changed from a step shape to a slope shape, thereby realizing the conversion between stairs and slopes, so that patients can perform rehabilitation training not only on stairs, but also on slopes, increasing the adaptability of the rehabilitation training stairs 1, improving the usability of the rehabilitation training stairs 1, and thus improving the training effect of patients.

[0048] In addition, after the rehabilitation training stairs 1 changes from a step shape to a slope shape, the sponge pad 108 is used to mark the patient's moving distance on the rehabilitation training stairs 1, so that medical staff can intuitively see the patient's climbing distance and assess the patient's rehabilitation degree.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the appended claims of the application.
