Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, and in particular to a wheelchair bending support assistive device. Background Technology

[0002] As people with disabilities increase their demand for greater autonomy in mobility, the functionality of wheelchairs, as an important mobility aid, is receiving increasing attention. Currently, wheelchairs on the market mainly focus on mobility and seating comfort. However, they lack effective support structures when users need to bend over, resulting in at least the following drawbacks in the use of existing wheelchairs: 1. When bending over, the center of gravity of existing wheelchair users shifts forward, making it difficult to maintain balance by relying solely on the wheelchair armrests or seat back, which can easily lead to excessive forward leaning, causing the wheelchair to tip over or the user to fall; 2. Some existing users have insufficient limb strength, and bending over requires a lot of physical effort, and it is difficult to return to a sitting position smoothly after completing the movement, increasing the difficulty of use. Therefore, we have launched a new wheelchair bending support assistive device. Utility Model Content

The upper ends of the two primary support rods 1 are fixedly connected to a connecting component 2. The opposite ends of the two primary support rods 1 are movably connected to a rear wheel 3 via a connecting shaft. The front and rear right ends of the connecting component 2 are fixedly connected to a reinforcing rod 4. The lower ends of the two reinforcing rods 4 are fixedly connected to a front wheel 6. The right ends of the two reinforcing rods 4 are fixedly connected to a support component 5. The right ends of the two connecting components 2 and the left ends of the two reinforcing rods 4 are fixedly connected to a seat cushion structure 7. In this embodiment, the connecting component 2 includes a first round rod 21, and two first round rods 21 are provided. A fixing ring 22 is sleeved on the upper part of the outer surface of each of the two first round rods 21. A connecting strip 23 is adhered to the outer surface of each of the two fixing rings 22. A limit strip 24 is fixedly connected to the opposite end of each of the two connecting strips 23. A first connecting ring 25 is fixedly sleeved on the middle part of the outer surface of each of the two first round rods 21. Both first connecting rings 25 are fixedly connected to the seat cushion structure 7. The two first connecting rings 25 are respectively located between the two longitudinal fixing rings 22.

[0018] The above scheme involves fixing the two No. 1 connecting rings 25 to the seat cushion structure 7 to reinforce the seat cushion structure 7, and wrapping and adhering the two sets of transverse connecting straps 23 to the two sets of fixing rings 22 to connect the two limiting straps 24 to the two sets of transverse fixing rings 22, thereby fixing the patient's upper limb and improving stability.

[0019] In this embodiment, the support component 5 includes two second support rods 51. Each second support rod 51 has a fixedly connected upper frame 52. A support structure 53 is interlocked through the upper ends of both frames 52. A first strap 54 is fixedly connected to the outer surface of each frame 52. A limit frame 55 is fixedly fitted onto the outer surface of each strap 54. Each second support rod 51 is fixedly connected to two reinforcing rods 4. A support rod 56 is fixedly connected to the lower right side of each second support rod 51. A support plate 58 is fixedly connected to the lower end of each support rod 56. The outer surface is fitted with a No. 2 strap 57 in the middle; the support structure 53 includes a fixing rod 531, there are two fixing rods 531, the upper part of the opposite ends of the two fixing rods 531 is fitted with an extension rod 533, the upper part of the outer surface of the two fixing rods 531 is fitted with a rubber handle 532, the upper right side of the outer surface of the two fixing rods 531 is fixedly connected with a handrail 535, the outer surface of the two fixing rods 531 is fitted with a breathable cotton cover 534, the lower part of the outer surface of the two fixing rods 531 is fitted with a No. 2 connecting ring 536, and the two No. 2 connecting rings 536 are fixedly connected to the two reinforcing rods 4 respectively.

[0020] The above scheme involves using two No. 1 straps 54 to limit and bind the patient's legs, and using two No. 2 straps 57 to fix the ankles to the wheelchair, preventing lower limb displacement and improving stability. Two support plates 58 support the patient's feet respectively. By adjusting the connection length between the two fixing rods 531 and the extension rod 533, the support component 5 can be easily installed on wheelchairs of different sizes and widths. The breathable cotton cover 534 can be used for easy bending support, improving stability.

[0021] It should be noted that this utility model is a wheelchair leaning support assist device. During use, after the patient sits in the wheelchair, two No. 1 straps 54 are used to limit and bind the patient's legs. This binding method can effectively restrict the range of motion of the legs and prevent the legs from moving freely during wheelchair use, providing a foundation for overall stability. Two No. 2 straps 57 are used to firmly fix the patient's ankles to the wheelchair. This operation avoids lower limb displacement caused by natural swinging of the lower limbs or slight external interference, further enhancing the stability of the lower limbs in the wheelchair and ensuring the patient's comfort during use. During wheelchair use, the lower limbs remain relatively fixed. Two support plates 58 support the patient's feet, bearing their weight and providing comfortable support. This reduces discomfort caused by prolonged dangling or improper foot placement and also helps maintain balance from a biomechanical perspective. Two restraint straps 24 are wrapped around and connected to the patient's upper limbs. These straps restrict excessive movement of the upper limbs and provide restraint for the overall fixation. Two sets of transverse connecting straps 23 are wrapped around and bonded to two sets of transverse fixing rings 22. The attachment connection secures the patient's armpit area, tightly connecting the patient's body to the wheelchair. This fixation effectively prevents the patient from leaning forward at an angle greater than 45°. When the patient's body tends to lean forward, the connection structure of the connecting strap 23 and the fixing ring 22 provides a counter-pulling force to prevent excessive forward leaning, thereby improving the overall stability of the patient sitting in the wheelchair. By adjusting the connection length between the two fixing rods 531 and the extension rod 533, the overall width of the support component 5 can be changed. Wheelchairs of different widths have different internal spaces and structures. By adjusting the connection length between the fixing rods 531 and the extension rod 533, the support component 5 can be adapted to wheelchairs of various sizes, ensuring that the assistive device can be installed on different models of wheelchairs and function properly. The breathable cotton cover 534 is fitted over the relevant components. When the patient bends over, the breathable cotton cover 534 provides a soft and comfortable contact surface, reducing friction between the components and the body, making the patient's movements such as bending over smoother and preventing discomfort due to overly hard components or excessive friction. This facilitates the patient's bending support movements and improves the flexibility of use.
