Description

Technical Field

[0001] This utility model relates to the field of orthopedic rehabilitation equipment technology, and in particular to an orthopedic rehabilitation walking aid. Background Technology

[0002] Orthopedic rehabilitation walkers are specially designed assistive devices to support patients who have experienced mobility impairments after orthopedic surgery or due to musculoskeletal disorders. These devices not only aid in daily mobility but also play a crucial role in helping patients gradually regain walking ability and physical function during rehabilitation training.

[0003] According to the patent with patent authorization announcement number CN208573977U, an assistive device for orthopedic rehabilitation treatment is disclosed, including a support leg assembly, a horizontal tie rod assembly, a fixing rod assembly, and a horizontal bandage reel. The support leg assembly includes two sets of support legs, which are connected and fixed by the horizontal tie rod assembly. A fixing rod assembly is provided in the middle of one set of support legs, and a horizontal bandage reel is provided on the fixing rod assembly.

[0004] Although the walker designed in this patent can help orthopedic patients gradually regain their walking ability during rehabilitation training, its supporting leg adopts a one-piece construction. This design, due to the lack of an effective cushioning mechanism, cannot adequately absorb and reduce the impact force from the ground when the patient moves the walker, resulting in greater vibrations being directly transmitted to the patient's joints, which may cause or aggravate joint discomfort in orthopedic patients. Summary of the Invention

[0005] In order to overcome the shortcomings of the walking aids in the above-mentioned patents, which lack cushioning design and may easily cause joint discomfort in orthopedic patients, the purpose of this utility model is to provide an orthopedic rehabilitation walking aid.

[0006] The present invention provides a rehabilitation walking aid for orthopedics, comprising a support leg assembly, a buffer mechanism, and telescopic rods. The support leg assembly includes two support legs, with two telescopic rods connected to the upper and lower sides of each support leg. Buffer mechanisms are symmetrically arranged on each support leg. Each buffer mechanism includes a lower connecting rod, an upper connecting cylinder, and an elastic element. An elastic element is fitted around the outer side of the lower connecting rod, with its bottom end connected to the lower connecting rod. The bottom end of the lower connecting rod is connected to the support leg. The top end of the elastic element is connected to the upper connecting cylinder, which in turn connects to the inner top end of the upper connecting cylinder. The top end of the upper connecting cylinder is connected to the support leg. The upper part of the lower connecting rod does not directly contact the upper connecting cylinder.

[0007] In one embodiment, the upper part of the support leg is a U-shaped round tube, the lower part is a round tube symmetrically arranged on the left and right sides, and the telescopic rod is a three-section telescopic round tube.

[0008] In one embodiment, the system further includes a rotating plate, a control switch, and a sliding wheel. Each of the two support legs has a notch on the lower part of the circular tube on the side where they are close to each other. A rotating plate is rotatably connected to each notch. A control switch is provided on the upper part of each rotating plate, and a sliding wheel is rotatably connected to the lower part of each rotating plate.

[0009] In one embodiment, a buffer pad is also included, with each lower connecting rod covered with a buffer pad, the bottom end of which contacts the lower end face of the lower connecting rod.

[0010] In one embodiment, a sponge sleeve is also included, with the top of each of the two support legs covered with a sponge sleeve.

[0011] In one embodiment, the sponge sleeve has spaced friction grooves.

[0012] The present invention has the following advantages: 1. By designing a buffer mechanism on the support leg, a flexible connection between the lower connecting rod and the upper connecting cylinder is achieved through an elastic element, so that during the patient's movement, the elastic element can effectively absorb and reduce the impact force from the ground, reduce the possibility of vibration being transmitted to the patient's joints, and improve the comfort of orthopedic patients.

[0013] 2. The combination of a rotating plate, control switch, and sliding wheels enables convenient movement of the walker. When it is necessary to move the walker, simply rotate the sliding wheels to the bottom of the support legs to push the walker forward, greatly facilitating its daily use.

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] An orthopedic rehabilitation walking aid, such as Figures 1-4 As shown, the walker includes a support leg assembly 1, a buffer mechanism 2, and telescopic rods 3. The support leg assembly 1 includes two support legs, with the upper part of each support leg being a U-shaped round tube and the lower part being round tubes symmetrically arranged on both sides. Two telescopic rods 3 are connected to the upper and lower sides of the two support legs. The telescopic rods 3 are three-section telescopic round tubes. When the telescopic rods 3 are fully retracted, they are one-third of their total length, bringing the distance between the two support legs closer together. This reduces the space required for the walker and makes it easier for people to store it. Buffer mechanisms 2 are symmetrically arranged on both support legs. The buffer mechanisms 2 are used to absorb vibrations generated during the movement of the walker. The buffer mechanism 2 includes a lower connecting rod 201, an upper connecting rod 202, and a lower connecting rod 203. The lower connecting rod 201 is fitted with an elastic element 203, and the bottom end of the elastic element 203 is connected to the lower connecting rod 201. The bottom end of the lower connecting rod 201 is connected to the support leg. The top end of the elastic element 203 is connected to the upper connecting rod 202, and the top end of the elastic element 203 is connected to the inner top end of the upper connecting rod 202. The top end of the upper connecting rod 202 is connected to the support leg. The upper part of the lower connecting rod 201 is not in direct contact with the upper connecting rod 202. The elastic element achieves a flexible connection between the lower connecting rod 201 and the upper connecting rod 202, so that the elastic element 203 can effectively absorb and reduce the impact force from the ground during the patient's movement.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a rotating plate 4, a control switch 5, and a sliding wheel 6. Each of the lower circular tubes on the side where the two support legs are close together has a notch 101, and a rotating plate 4 is rotatably connected to each notch 101. A control switch 5 is located on the upper part of each rotating plate 4, and a sliding wheel 6 is rotatably connected to the lower part of each rotating plate 4. When it is necessary to move the walker, the control switch 5 can be rotated to allow the rotating plate 4 to rotate. Rotating the rotating plate 4 causes the sliding wheel 6 to rotate to the bottom end of the support leg (e.g., ...). Figure 1 (As shown), then rotate the control switch 5 to fix the rotating plate 4, which will push the walker to move, making it convenient for people to carry the walker.

[0022] like Figures 1-4As shown, it also includes a cushioning pad 204 and a sponge sleeve 7. The lower connecting rod 201 is covered with a cushioning pad 204, which further absorbs vibration. The bottom end of the cushioning pad 204 contacts the lower end face of the lower connecting rod 201. The top of both support legs is covered with a sponge sleeve 7. The sponge sleeve 7 has friction grooves 701 spaced apart. The sponge sleeve 7 increases the comfort of hand grip. The sponge material is soft and has good shock absorption performance, which can relieve hand fatigue that may be caused by prolonged use. The friction grooves 701 increase the friction between the fingers and the sponge sleeve 7, ensuring that orthopedic patients can firmly grip the walker even when sweating, and avoid slipping.

[0023] Before orthopedic patients use this walking aid for rehabilitation training, they pull the front supporting leg to fully extend the telescopic rod 3, opening the walking aid. The orthopedic patient stands between the two supporting legs, holding the front and rear foam sleeves 7 with both hands. When the orthopedic patient lifts the walking aid forward and lowers it to the ground, the impact force from the ground first acts on the lower circular tube of the supporting leg. At this time, the lower circular tube of the supporting leg will vibrate. This vibration is transmitted through the supporting leg to the lower connecting rod 201. As the lower connecting rod 201 moves upward along the inner wall of the upper connecting cylinder 202, the vibration is further transmitted to the elastic element 203. The elastic element 203 changes from the initial state to a compressed state, effectively absorbing and reducing the impact energy from the ground. This process... This greatly reduces the upward transmission of vibration to the upper part of the support leg, thus ensuring that the walker can move smoothly and significantly reducing the possibility of vibration being transmitted to the patient. When the user applies downward pressure to the foam sleeve 7, the pressure is transmitted to the support leg through the foam sleeve 7, and then to the upper connecting cylinder 202. The upper connecting cylinder 202 transmits the pressure to the elastic element 203, which changes from its initial state to a compressed state. The elastic element 203 converts the pressure into elastic potential energy. When the pressure exerted on the support leg by the orthopedic patient is reduced, the elastic element 203 changes from a compressed state to its initial state, releasing the stored energy and providing a certain supporting force to the orthopedic patient, which helps the orthopedic patient lift the walker and move forward.
