Description

Technical Field

[0001] This utility model relates to the field of rehabilitation assistive device technology, and in particular to a walking aid for paralyzed patients due to stroke, injury, etc. Background Technology

[0002] Walking aids used in rehabilitation training are medical devices used to assist the lower limbs when they cannot move effectively. For example, patients who have undergone surgery for avascular necrosis of the femoral head need to get out of bed and exercise after the surgery. Some patients with fractures, strokes and other diseases need to exercise their limbs and practice walking during their rehabilitation phase. If they cannot undergo effective rehabilitation training, they will have some muscle atrophy problems and need to carry out long-term training to ensure their recovery.

[0003] There are currently various types of walking aids, such as the commonly used single-leg walking aids (canes) and four-wheel walking aids. Four-wheel walking aids have good stability and are suitable for patients who are just starting rehabilitation training and have poor standing balance. Single-leg walking aids are suitable for elderly people or patients who are in a better state of rehabilitation, have a certain amount of upper limb support, and can also move their lower limbs on their own.

[0004] Most walking aids are fixed in design, but many patients undergo a gradual recovery process over time. Initially, they need a four-wheeled walking aid. As their condition improves and their lower limbs gain some weight-bearing capacity, they can move independently. Later, they may only need a single-leg walking aid on both sides, and eventually, they may only need a walking aid on one side. Therefore, purchasing multiple walking aids for a single recovery cycle is a heavy burden for patients and a waste of resources. Summary of the Invention

[0005] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a single-leg walking aid for rehabilitation training.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a single-leg walking aid for rehabilitation training, including a vertical support and a handrail above the vertical support.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1 like Figure 1 The single-leg walking aid for rehabilitation training shown includes a vertical support 1 and a handrail 101 located above the vertical support. The middle part of the vertical support 1 is provided with a folding connecting sleeve 103, which is sleeved on the vertical support 1. The lower end of the vertical support 1 is provided with a connector 2, and the connector 2 is provided with a connecting rod 3. The connecting rod 3 is covered with two foot connecting sleeves 4, which are located on both sides of the vertical support 1. The foot body 5 is provided below the foot connecting sleeves 4. When the patient needs the single-leg walking aid, it can be used directly.

[0025] Specifically, the outrigger connecting sleeve 4 is detachably connected to the outrigger body 5. The outrigger connecting sleeve 4 has connecting ears 401 on both sides, and a first through hole 402 is opened on the connecting ears 401. The outrigger body 5 is provided with a connecting bolt, which passes through the first through hole 402 and is fixed with a first nut. In this way, the outrigger body 5 can be replaced as needed. Alternatively, the outrigger body 5 can be removed to reduce weight when using the four-wheel walking aid, making it more flexible to use.

[0026] Specifically, the support body 5 is an integral structure, or the support body 5 includes a connecting plate with multiple supporting feet below the connecting plate, which can be selected according to existing technology and cost.

[0027] Example 2 A four-wheeled walking aid for rehabilitation training includes a front wheel assembly 6, a rear wheel assembly 7, and a hinge frame 8. It also includes two sets of the aforementioned single-leg walking aids, which are connected together by the hinge frame 8. The front wheel assembly 6 is mounted on the front end of the connecting rod 3 via a front mounting rod 603, and the rear wheel assembly 7 is mounted on the rear end of the connecting rod 3 via a rear mounting rod 701. In this way, the two single-leg walking aids can be connected together by the hinge frame 8. By installing the front wheel assembly 6 in front of each single-leg walking aid and the rear wheel assembly 7 in the rear, a four-wheeled walking aid can be assembled. This aid is used when the patient is in the early stage of recovery, has poor self-control, and needs to bear a relatively large load.

[0028] Specifically, the hinge frame includes two folding rods 8, which are hinged together by a hinge shaft 801. A fixing frame is provided between the two folding rods 8 to open the two folding rods 8. The fixing frame is a horizontal plate 9 or a horizontal bar. When a horizontal plate 9 is used, the patient can sit down and rest when tired during rehabilitation training, which can be used as a seat. If a horizontal bar is used, the weight of the walker can be reduced, making the walker lighter.

[0029] Specifically, the vertical support 1 is provided with a folding connecting sleeve 103, which is sleeved on the vertical support 1. The folding connecting sleeve 103 is provided with a folding connecting frame 104, which can be connected by interference fit, glue, or bolts. The upper end of the folding rod 8 is provided with a folding mounting rod 802, which is detachably assembled on the folding connecting frame 104. The folding connecting frame 104 is designed with a C-shaped structure and the opening faces upward. The folding mounting rod 802 is snapped into the folding connecting frame 104. It can also be further fixed by bolts passing through the folding mounting rod 802 and the folding connecting frame 104. Alternatively, the horizontal plate 9 can be installed on the folding mounting rod 802 with bolts.

[0030] Specifically, the lower end of the folding rod 103 is provided with a folding mounting sleeve 803, and one side of the connector 2 is provided with a mounting ear 201. The folding mounting sleeve 803 is assembled on the mounting ear 201 by a pin. Both ends of the pin are provided with external thread sections, and nuts are fitted on the external thread sections to facilitate the disassembly of the shaft. When a single-leg walking aid is needed, the folding rod 8 can be disassembled.

[0031] Specifically, the front wheel assembly 6 adopts a caster assembly, including a roller 601, a caster frame 602, and a support frame 603. The caster frame 602 is mounted on the support frame 603, and the caster frame 602 and the support frame 602 can rotate relative to each other in the horizontal direction. The roller 601 is mounted on the caster frame 602 through a pivot and bearing. Alternatively, casters with directional positioning and braking functions can be used. This is existing technology, and suitable casters can be selected directly according to needs.

[0032] Specifically, the connecting rod 2 is inclined relative to the vertical support 1, with the front end pointing upwards and the rear end pointing downwards, which facilitates the installation of the universal wheel assembly. At this time, the lower surface of the support body 5 is perpendicular to the vertical support 1, and when it is a single-leg walking aid, it can level the ground.

[0033] When the articulation frame needs to be removed, first remove the fixing frame, then remove the folding mounting rod 802, and then remove the pin between the folding mounting sleeve 803 and the mounting ear 201. In this way, the articulation frame can be separated from the single-leg walking aid.
