Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a multi-mode rehabilitation training crutch. Background Art

[0002] As a seemingly simple yet crucial walking aid, crutches have always accompanied every patient with leg injuries. They are not only an indispensable part of the daily operation of hospitals but also an important support in the patient's rehabilitation journey. However, when we delve into the actual utility and functions of these crutches, we find that they may not fully meet the expectations of patients and medical staff.

[0003] Most of the current medical crutches on the market have relatively single functions and mainly serve as a support tool for patients when walking. Although their original design intention is to reduce the physical burden on patients, in actual applications, many limitations have emerged. For example, when walking on a flat ground, the crutches can provide stable support for patients; however, when patients face complex environments such as climbing stairs, the crutches seem inadequate. This is mainly because the existing crutches lack the ability to be flexibly adjusted according to the usage environment and are unable to connect with structures such as stair railings skillfully, thus increasing the risk of patients falling.

[0004] In addition, the fracture conditions and rehabilitation needs of different patients also vary greatly. Some patients have a single leg injury and need the crutches to provide stable support on one side; while some patients have both legs injured, and at this time, the single support function of the crutches seems unable to meet the personalized needs of patients. Facing these complex and changeable situations, the existing medical crutches seem inadequate and unable to provide precise and effective assistance to patients. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art and provide a multi-mode rehabilitation training crutch.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A multi-mode rehabilitation training crutch, including a support part, a telescopic part, an armrest part, and a support crossbar. The telescopic part is used to connect the support part and the armrest part. The telescopic part includes a first telescopic component and a second telescopic component. A connection component is provided between the first telescopic component and the second telescopic component, and the connection component is used to fix the first telescopic component and the second telescopic component. A grasping device is slidably connected to the first telescopic component and the second telescopic component, and the grasping device is used to grasp the railing and fix the first telescopic component and the second telescopic component. A control component for controlling the grasping device is provided on the armrest part. The support crossbar is arranged above the armrest part, and the support crossbar is used to support the patient's armpit.

[0007] The working principle of the present invention is as follows: before use, the corresponding mode is selected according to the needs of the patient. For example, if the patient only needs to be supported on one side, the first telescopic component and the second telescopic component are combined together and fixed by the connecting component. When the patient needs to be supported on both sides, the first telescopic component and the second telescopic component are separated to become two crutches. This solution can meet the needs of different patients. When the patient needs to exercise by climbing stairs during rehabilitation or climb stairs after discharge, whether it is two crutches or one crutch, the method is the same, that is, first adjust the height of the gripping device so that the gripping device Located at the same height as the horizontal bar of the fence, the gripping device is first inserted into the horizontal bar. When it is necessary to climb the stairs, the patient first places the supporting horizontal bar under the armpit and holds it at the control component. The gripping device is gripped on the horizontal bar through the control component to fix the crutch. At this time, if the patient falls backwards, he can also fix on the crutch by hand strength, seek help from others or get up slowly by himself. When the crutch needs to be moved, release the control component, release the gripping device from the horizontal bar, move the crutch until it is suitable, and fix the crutch on the horizontal bar again through the control component. Repeat the above steps until the stairs are completed.

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figures 1-9As shown, the multi-modal rehabilitation training crutch includes a support portion 1, a telescopic portion 2, an armrest portion 3 and a support cross bar 38. The telescopic portion 2 is used to connect the support portion 1 and the armrest portion 3. The telescopic portion 352 includes a first telescopic component 4 and a second telescopic component 5. A connecting component 6 is arranged between the first telescopic component 4 and the second telescopic component 5. The connecting component 6 is used to fix the first telescopic component 4 and the second telescopic component 5. A gripping device 7 is slidably connected to the first telescopic component 4 and the second telescopic component 5. The gripping device 7 is used to grip the fence and fix the first telescopic component 4 and the second telescopic component 5. A control component 8 for controlling the gripping device 7 is arranged on the armrest portion 3. The support cross bar 38 is arranged above the armrest portion 3. The support cross bar 38 is used to support the patient's armpits.

[0030] To further explain, the grasping device 7 includes a connecting arc plate 9, a rotating connecting member 10, a supporting arc plate 11 and a movable clamping block 12. The connecting arc plate 9 is used to connect the first telescopic component 4 or the second telescopic component 5. The rotating connecting member 10 is used to connect the connecting arc plate 9 and the supporting arc plate 11. The movable clamping block 12 is arranged on the supporting arc plate 11, and the movable clamping block 12 can be close to or away from the supporting arc plate 11. Through the design of the rotating connecting member 10, the grasping device 7 can be folded and stored when not in use, so that the grasping device 7 does not affect the use of the crutch.

[0031] In further detail, the rotating connecting member 10 includes a rotating support rod 13 and a connecting block 14, and a connecting rod 15 is arranged at one end of the rotating support rod 13 close to the connecting arc plate 9, and a clearance hole 16 for the connecting rod 15 to pass through is arranged on the connecting arc plate 9, and a first clearance groove 17 and a second clearance groove 18 are arranged on both sides of the clearance hole 16, respectively, and the first clearance groove 17 and the second clearance groove 18 are arranged on the top surface and the bottom surface of the connecting arc plate 9, respectively, and the first clearance groove 17 and the second clearance groove 18 are used to accommodate the connecting rod 15, and a rubber layer 19 is arranged at one end of the connecting rod 15 close to the telescopic part 2, which is arranged to enable the rotating support rod 13 to be positioned vertically to the telescopic part 2 or in a manner approximately parallel to it. On one side of the telescopic part 2, the supporting arc plate 11 can also be clipped onto the telescopic part 2 for fixation. When the connecting rod 15 is perpendicular to the telescopic part 2, the connecting arc part can be fixed at this position. A first clearance groove 17 and a second clearance groove 18 are provided so that they can be located on one side of the telescopic part 2 in a nearly parallel manner. A rubber layer 19 is provided so that the connecting rod 15 and the telescopic part 352 will not be damaged by friction. The connecting block 14 is used to rotate the connecting supporting arc plate 11. At the same time, when the patient needs to rest after walking for a long time, the connecting arc plate 9 can be adjusted to the lowest point so that the rotating support rod 13 is located near the height of the patient's knees. The patient can place his legs above the rotating support rod 13 to rest.

[0032] Specifically, buckles 20 are provided at both ends of the connecting arc plate 9, and sliding grooves 21 for the buckles 20 to slide are provided on both the first telescopic component 4 and the second telescopic component 5. This setting is used to adjust the height of the grasping device 7 so that it can conform to handrails in different places.

[0033] Specifically, the control component 8 includes an output handle 22, a first input cylinder 23, a first output cylinder 24, and a connecting oil pressure pipe 25. The output handle 22 is rotatably connected to the handrail portion 3. The output handle 22 is used to squeeze the piston of the first input cylinder 23. The connecting oil pressure pipe 25 is used to connect the first input cylinder 23 and the first output cylinder 24. The first output cylinder 24 is provided on the supporting arc plate 11, and the piston of the first output cylinder 24 is connected to the moving clamp 12. When in use, only by rotating the output handle 22, the pressure can be transmitted to the first output cylinder 24 to push the moving clamp 12 away from the supporting arc plate 11, so that the moving clamp 12 approaches the cross bar of the guardrail and clamps on the cross bar of the guardrail, thereby fixing the crutch.

[0034] Specifically, the moving clamp 12 is U-shaped. A ball 26 is provided at one end of the supporting arc plate 11 close to the moving clamp 12. The position of the ball 26 is inside the U-shape of the moving clamp 12. When there is no external force, the height of the ball 26 is higher than that of the moving clamp 12, so that when the grasping device 7 moves on the cross bar, it is rolling friction, which is convenient for movement. When the output handle 22 is pressed, the moving clamp 12 moves, so that the height of the moving clamp 12 is higher than that of the ball 26, and the rolling friction is adjusted to fixed friction to increase the friction force.

[0035] Specifically, the control component 8 further includes a second input cylinder 27, a second output cylinder 28, a top block 29, and a connecting oil pressure pipe 25. The piston of the second input cylinder 27 is connected to the output handle 22. The second output cylinder 28 is provided on the support portion 1. The top block 29 is connected to the piston of the second output cylinder 28. The connecting oil pressure pipe 25 is used to connect the second output cylinder 28 and the second input cylinder 27. This setting is used to finely adjust the length of the crutch. Since the crutch needs to be connected to the cross bar when climbing stairs and needs to be shortened by a certain distance when crossing stairs, this design is adopted so that when the crutch is fixed, the top block 29 protrudes and contacts the ground. When the turning handle is released, the top block 29 contracts so that the crutch does not contact the ground, which is convenient for moving to the next step.

[0036] Specifically, the connecting component 6 includes a first arc-shaped clamping block 30 and a second arc-shaped clamping block 31. A first clamping groove 32 for the second arc-shaped clamping block 31 to snap into is provided on the first telescopic component 4, and a second clamping groove 33 for the first arc-shaped clamping block 30 to insert into is provided on the second telescopic component 5. The first arc-shaped clamping block 30 is rotatably connected to the first telescopic component 4, and the second arc-shaped clamping block 31 is rotatably connected to the second telescopic component 5. This setting is used for quickly installing or disassembling the first telescopic component 4 and the second telescopic component 5, facilitating use by different patients or in different road conditions.

[0037] Specifically, both the first telescopic component 4 and the second telescopic component 5 include a fixed part 34 and a sliding part 35. The first arc-shaped clamping block 30, the second arc-shaped clamping block 31, the first clamping groove 32, and the second clamping groove 33 are all provided on the fixed part 34. The grasping device 7 is arranged on the sliding part 35, and the height of the sliding part 35 is adjustable, which can be achieved in different ways, such as spring buckles 20, friction fixation, etc. The first arc-shaped clamping block 30 and the second arc-shaped clamping block 31 are both slidably connected to the sliding part. The arc degrees of both the first arc-shaped clamping block 30 and the second arc-shaped clamping block 31 are greater than 180 degrees and have a certain elasticity. One end of both the first arc-shaped clamping block 30 and the second arc-shaped clamping block 31 is provided with a fixing hook for inserting into the first clamping groove 32 or the second clamping groove after rotating one circle for fixation.

[0038] Specifically, a display screen 36 is provided on the armrest part 3, and a pressure sensor 37 is provided on the bottom surface of the support part 1. The display screen 36 is used to display the data of the pressure sensor 37. This setting is used to detect the force-bearing situation of the patient when using the crutch and adjust the patient's usage method according to the data.

[0039] Specifically, anti-slip patterns are provided at the bottom of the support part 1.
