Abstract

This invention provides an assistive walking device for medical rehabilitation training. A transition frame is rotatably connected to the inner side of the upper end of a support column, and a crossbar is rotatably connected to the lower end of the support column. A slider is slidably connected to the lower end of one side of the crossbar, and a telescopic rod is slidably connected to the inner side of the lower end of the slider. A suction cup is slidably connected to the lower end of the telescopic rod. The transition frame is concave and consists of five cylinders, all rotatably connected. The upper end of the support column and the retaining ring rotate 360° via the transition frame. Due to the shape of the track, after the slider slides upwards, it drives the push rod to slide downwards back to its original position via a rotating ball. This allows the concave surface of the retaining ring on one side of the push rod to return to its original position, achieving a cushioning effect for the patient's waist. When the patient leans forward, the retaining ring further cushions the patient's waist.

Description

Technical Field

[0001] This invention relates to the field of physiotherapy devices, and more particularly to an assistive walking device for medical rehabilitation training. Background Technology

[0002] When patients have difficulty walking in their lower limbs, they need to use assistive walking devices for medical rehabilitation. The main method for treating lower limb movement disorders is to passively flex the patient's hip and knee joints with the help of family members. This method is labor-intensive and cannot be sustained. Once the external force is reduced, the limbs are in an external rotation position, which cannot keep the patient in a functional position for a long time. Assistive walking devices can help to achieve this. This article provides technical insights into assistive walking devices.

[0003] The research on assistive walking devices has revealed the following problems:

[0004] When assisting patients with walking, since patients usually have lower limb motor disorders, when the patient leans forward due to weakness in the lower limbs, the assistive walking device is easily pulled forward by the patient as a whole. This means that the assistive walking device cannot further cushion the patient or slow down the forward leaning time when the patient leans forward. As a result, it cannot prevent the patient from leaning forward quickly, resulting in the patient's upper limbs not being able to provide support and protection.

[0005] Currently, the prior art CN202311422211.X discloses an auxiliary walking device for post-orthopedic rehabilitation training. This invention features an instrument plate mounted on the top surface of a supporting base plate. Two first threaded circular grooves are formed on the top surface of the instrument plate. Two handrails are provided on the top surface of the instrument plate. A first connecting hole is formed on the outer circular wall of each handrail. A first bolt is movably sleeved on the inner circular wall of the first connecting hole. The first bolt is threadedly connected to the first threaded circular groove. Several sliding grooves are formed on the outer circular wall of each handrail. A connecting ring is movably sleeved on the outer circular wall of each handrail. This device provides auxiliary support for relatively healthy patients, facilitating further rehabilitation training. For patients just beginning rehabilitation training, it provides assisted walking, increasing the user base of the device. Simultaneously, it improves patient comfort during rehabilitation training.

[0006] The present invention mainly solves the problem that the assistive walking device cannot further cushion the patient and slow down the forward tilting time when the patient is tilting forward. Summary of the Invention

[0007] To address the aforementioned technical problems, the present invention provides an assistive walking device for medical rehabilitation training, thereby resolving the issues described in the background section.

[0008] The purpose and effect of the present invention for an auxiliary walking device for medical rehabilitation training are achieved by the following specific technical means: an auxiliary walking device for medical rehabilitation training includes a main frame, a horizontal plate passing through the upper end of the main frame, rollers rotatably connected to the four corners of the main frame, a base provided at the upper end of the horizontal plate, and a support column oscillatingly connected to the inner side of the base.

[0009] Furthermore, handrails are installed on both sides of the upper end of the main frame, and the main frame as a whole moves by rollers.

[0010] Furthermore, the base is hollow inside, and a groove is provided at the lower end of the base. The groove is circular, and a pad is surrounded on the inner side of the upper end of the base. The pad is inclined upward and is made of iron. The pad is surrounded on the outside of the support column.

[0011] Furthermore, the lower end of the support extends into the interior of the base, and the upper end of the support is provided with a retaining ring.

[0012] Furthermore, the retaining ring is arc-shaped, with a thickness of 5-10cm, and is made of a deformable and flexible material, such as rubber.

[0013] Furthermore, the lower end of the retaining ring is provided with a track, and a slide rod is slidably connected to the inner side of the upper end of the track. A rotating ball is rotatably connected to the upper end of the slide rod, and a push rod is fitted onto the upper end of the rotating ball. The end of the push rod away from the rotating ball is installed on the inner wall of the retaining ring.

[0014] Furthermore, the track is arc-shaped with an arc angle of 180°, the track is arranged vertically, and the slide rod slides in an arc shape inside the track.

[0015] Furthermore, the slide bar is in an inverted "T" shape, and multiple sets of slide bars, tracks, push rods and rotating balls are provided in combination, with the slide bars, tracks, push rods and rotating balls evenly arranged inside the retaining ring.

[0016] Furthermore, the push rod is located on the concave surface of the retaining ring, the push rod is arranged at an inclination of 5-25°, the end of the push rod near the rotating ball is inclined downward, and the push rod is connected to the slide rod through the rotating ball.

[0017] Furthermore, an adapter frame is rotatably connected to the inner side of the upper end of the support column, a crossbar is rotatably connected to the lower end of the support column, a slider is slidably connected to the lower end of one side of the crossbar, a telescopic rod is slidably connected to the inner side of the lower end of the slider, and a suction cup is slidably connected to the lower end of the telescopic rod.

[0018] Furthermore, the adapter frame is concave and consists of 5 cylinders, which are rotatably connected to each other. The upper end of the support column and the retaining ring can rotate 360° through the adapter frame.

[0019] Furthermore, the slider slides inside the groove of the base, and a groove is provided at the lower end of the slider. The telescopic rod is slidably connected to the top of the groove, and the suction cup is slidably nested and connected to the groove in a perpendicular direction.

[0020] Furthermore, the telescopic rod is configured in two segments, and the telescopic rod is matched with the suction cup. When the slider is perpendicularly attached to the inside of the groove of the base, the distance between the suction cup and the inner wall of the groove of the base is 0.2-0.4cm.

[0021] Beneficial effects:

[0022] 1. When one side of the retaining ring is compressed by the patient's waist, the concave side of the retaining ring deforms. Since the push rods are arranged at an angle of 5-25°, the end of the push rod near the rotating ball is inclined downward. Therefore, when one side of the retaining ring is compressed and deformed, the push rod can slide towards the end of the rotating ball, while the slide rod slides in an arc shape inside the track. The push rod drives the slide rod to slide through the rotating ball, and the slide rod slides from bottom to top inside the track.

[0023] 2. Due to the shape of the track, after the slide bar slides upward, it drives the push bar to slide downward back to its original position through the rotating ball. This allows the concave surface of the retaining ring on one side of the push bar to return to its original position, thus achieving the effect of the retaining ring cushioning the patient's waist. When the patient leans forward, the retaining ring can further cushion the patient's waist.

[0024] 3. The upper end of the support and the retaining ring rotate 360° through the adapter frame. When the retaining ring is squeezed due to the patient falling forward, the retaining ring drives the upper end of the support to rotate horizontally through the adapter frame at a rotation angle of 360°. The rotation of the retaining ring can form a buffer during the patient's forward fall.

[0025] 4. When the support column continues to tilt due to the patient falling forward, the crossbar at the lower end of the support column simultaneously drives the slider to tilt. At this time, the slider is tilted inside the groove of the base, and the telescopic rod at the lower end of the slider slides downward. The suction cup extends into the groove of the base. The suction cup can further increase the overall stability of the connection between the slider and the base when the slider is tilted, thereby increasing the stability of the connection between the support column and the base, further slowing down the forward tilting speed of the support column and the retaining ring, and achieving a buffering effect when the patient falls forward.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0037] As attached Figure 1 To be continued Figure 8 As shown:

[0038] Example 1: An assistive walking device for medical rehabilitation training includes a main frame 1, a horizontal plate 101 passing through the upper end of the main frame 1, rollers 102 rotatably connected to the four corners of the main frame 1, a base 2 provided at the upper end of the horizontal plate 101, and a support column 3 oscillatingly connected to the inner side of the base 2.

[0039] Among them: main frame 1, handrails are installed on both sides of the upper end of main frame 1, and the main frame 1 as a whole is moved by rollers 102;

[0040] The base 2 is hollow inside. A groove is provided at the lower end of the base 2. The groove is circular. A pad 201 is surrounded on the inner side of the upper end of the base 2. The pad 201 is inclined upward and is made of iron. The pad 201 is surrounded on the outside of the support column 3.

[0041] The gasket 201 is tilted upwards. The gasket 201 is an iron sheet. The gasket 201 is wrapped around the outside of the support column 3. Therefore, when the support column 3 is tilted, the support column 3 is squeezed to one side of the gasket 201, and the gasket 201 is deformed.

[0042] When the support column 3 is not tilted, the pad 201 can provide support for the outer side of the support column 3;

[0043] The lower part of the interior of base 2 has a sliding groove, which is circular in shape. Please refer to the instruction manual for details. Figure 4 As shown;

[0044] The support column 3 extends into the interior of the base 2 at its lower end, and a retaining ring 4 is provided at the upper end of the support column 3.

[0045] The retaining ring 4 is arc-shaped and 5-10cm thick. It is made of a deformable and flexible material, such as rubber.

[0046] The retaining ring 4 is arc-shaped, with its concave surface close to the handrail end of the main frame 1. The retaining ring 4 is 5-10cm thick. When the retaining ring 4 engages with the patient's waist, it can increase the comfort of the patient's waist.

[0047] Wherein: the patient holds the handrail of the main frame 1 with his / her hand, and then the patient walks. The main frame 1 moves as a whole through the roller 102. When the patient leans forward, the patient's waist is locked in the inner side of the locking ring 4. The locking ring 4 causes the support column 3 to tilt at the upper end of the base 2.

[0048] Example 2: Refer to the attached instruction manual Figure 2 , 7 As can be seen from Figure 8, the difference between Embodiment 2 and Embodiment 1 is that the lower end of the retaining ring 4 is provided with a track 401, the inner side of the upper end of the track 401 is slidably connected with a slide rod 402, the upper end of the slide rod 402 is rotatably connected with a rotating ball 403, the upper end of the rotating ball 403 is fitted with a push rod 404, and the end of the push rod 404 away from the rotating ball 403 is installed on the inner wall of the retaining ring 4.

[0049] Among them: track 401, track 401 is set in an arc shape with an arc angle of 180°, track 401 is arranged vertically, and slide rod 402 slides in an arc shape inside track 401;

[0050] The slide bar 402 slides in an arc shape inside the track 401. Please refer to the instruction manual for details. Figure 8 As shown;

[0051] The slide bar 402 is in the shape of an inverted "T". Multiple sets of slide bar 402, track 401, push rod 404 and rotating ball 403 are provided. The slide bar 402, track 401, push rod 404 and rotating ball 403 are evenly arranged inside the retaining ring 4.

[0052] When the slide bar 402 is not sliding, it is located in the middle of the track 401. At this time, the slide bar 402 is at the bottom of the track 401. Please refer to the instruction manual appendix. Figure 8 As shown;

[0053] Push rod 404 is located on the concave surface of retaining ring 4. Push rod 404 is arranged at an angle of 5-25°. The end of push rod 404 near the rotating ball 403 is inclined downward. Push rod 404 is connected to slide rod 402 through rotating ball 403.

[0054] The push rods 404 are arranged at an angle of 5-25°. The end of the push rod 404 near the rotating ball 403 is inclined downward. Therefore, when one side of the retaining ring 4 is squeezed and deformed, the push rod 404 can slide towards one end of the rotating ball 403.

[0055] When one side of the retaining ring 4 is compressed by the patient's waist, the concave side of the retaining ring 4 deforms. Since the push rod 404 is arranged at an angle of 5-25°, the end of the push rod 404 near the rotating ball 403 is inclined downward. Therefore, when one side of the retaining ring 4 is compressed and deformed, the push rod 404 can slide towards the end of the rotating ball 403, while the slide rod 402 slides in an arc shape inside the track 401. The push rod 404 drives the slide rod 402 to slide through the rotating ball 403. The slide rod 402 slides from bottom to top inside the track 401.

[0056] Due to the shape of the track 401, after the slide bar 402 slides upward, the slide bar 402 drives the push bar 404 to slide downward back to its original position through the rotating ball 403. As a result, the concave surface of the retaining ring 4 on one side of the push bar 404 can return to its original position, so as to achieve the effect of the retaining ring 4 in cushioning the patient's waist. When the patient leans forward, the retaining ring 4 can further cushion the patient's waist.

[0057] Example 3: Refer to the appendix of the instruction manual Figure 2-6 It can be seen that the difference between Embodiment 3 and Embodiments 1-2 is that the inner side of the upper end of the support column 3 is rotatably connected to the adapter 302, the lower end of the support column 3 is rotatably connected to the crossbar 301, the lower end of one side of the crossbar 301 is slidably connected to the slider 303, the inner side of the lower end of the slider 303 is slidably connected to the telescopic rod 304, and the lower end of the telescopic rod 304 is slidably connected to the suction cup 305.

[0058] Among them: the adapter frame 302 is concave and consists of 5 cylinders. The cylinders are rotatably connected to each other. The upper end of the support column 3 and the retaining ring 4 can rotate 360° through the adapter frame 302.

[0059] The upper end of the support column 3 and the retaining ring 4 rotate 360° through the adapter frame 302. When the retaining ring 4 is squeezed due to the patient leaning forward, the retaining ring 4 drives the upper end of the support column 3 to rotate horizontally through the adapter frame 302.

[0060] The slider 303 and the crossbar 301 slide inside the groove of the base 2. The lower end of the slider 303 is provided with a groove. The telescopic rod 304 is slidably connected to the top of the groove. The suction cup 305 is slidably nested and connected to the groove in a perpendicular direction.

[0061] The telescopic rod 304 is configured in two segments. The telescopic rod 304 is matched with the suction cup 305. When the slider 303 is perpendicularly attached to the inside of the groove of the base 2, the suction cup 305 is 0.2-0.4cm away from the inner wall of the groove of the base 2.

[0062] When the slider 303 is perpendicularly attached to the inside of the groove of the base 2, the suction cup 305 is 0.2-0.4cm away from the inner wall of the groove of the base 2. At this time, the suction cup 305 cannot adhere to the inside of the groove of the base 2.

[0063] Wherein: the upper end of the support column 3 and the retaining ring 4 rotate 360° through the adapter frame 302. When the retaining ring 4 is squeezed due to the patient leaning forward, the retaining ring 4 drives the upper end of the support column 3 to rotate horizontally through the adapter frame 302. The rotation angle is 360°. The rotation of the retaining ring 4 can form a buffer during the patient's forward leaning process.

[0064] When the support column 3 continues to tilt due to the patient falling forward, the lower end crossbar 301 of the support column 3 simultaneously drives the slider 303 to tilt. At this time, the slider 303 is tilted inside the groove of the base 2, and the lower end telescopic rod 304 of the slider 303 slides downward. The suction cup 305 extends into the groove of the base 2. The suction cup 305 can further increase the overall stability of the connection between the slider 303 and the base 2 when the slider 303 is in a tilted state, thereby increasing the stability of the connection between the support column 3 and the base 2, further slowing down the forward tilting speed of the support column 3 and the retaining ring 4, and achieving the effect of buffering the patient when falling forward.
