Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, and in particular to an orthopedic nursing walking aid device. Background Technology

[0002] In the early stages after a fracture, patients need to avoid or minimize weight-bearing on the injured area. At this time, crutches or walking aids can be helpful, allowing patients to shift some of their body weight to the upper limbs, thus reducing the burden on the lower limbs and enabling necessary activities such as moving from bed to the bathroom or walking short distances within the ward. In the middle and later stages of fracture recovery, as patients gradually increase weight-bearing training, walking aids can provide stable support, helping patients relearn to walk and strengthening leg muscles and balance.

[0003] In some existing walking aids, the legs or uprights utilize a threaded structure. By rotating an adjustment component, the upright can be raised or lowered due to the threaded action, thereby changing the overall height of the walking aid. For example, some walking aids have rotatable knobs on their legs; rotating the knob extends or shortens the legs to meet the needs of patients of different heights.

[0004] However, in actual use, the height of the fixed bar cannot be adjusted, making it difficult to adapt to users of different heights. For taller people, a fixed bar that is too low will force them to bend over or kneel, increasing physical fatigue and potentially causing pain in the lower back, knees, and other areas with prolonged use. For shorter people, a fixed bar that is too high will require them to strain to raise their arms to grip it, easily causing soreness in their arm and shoulder muscles and resulting in a poor user experience. To address the above issues, an orthopedic nursing walking aid device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an orthopedic nursing walking aid device, which aims to improve the problem that some existing devices cannot adjust the position of the fixing rod.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An orthopedic nursing walking aid includes a transverse support rod, with a support frame fixedly connected to the left and right sides of the transverse support rod. A limit plate is slidably connected to the front and rear sides of the inner side of the support frame. A fixing rod is fixedly connected to the bottom of the limit plate. A position adjustment mechanism is fixedly connected to the front and rear sides of the outer side of the support frame. A tension adjustment mechanism is fixedly connected to the rear side of the outer side of the support frame. The position adjustment mechanism includes a mounting frame, a connecting shaft is fixedly connected inside the mounting frame, a rotating plate is rotatably connected to the outside of the connecting shaft, an elastic component is provided on the outside of the rotating plate, a locking rod is fixedly connected to the other end of the rotating plate, and the mounting frame is fixedly connected to the front and rear sides of the outside of the support frame. As a further description of the above technical solution: The elastic component includes a telescopic rod, a spring is sleeved on the outside of the telescopic rod, and the outside of the telescopic rod is fixedly connected to the outside of the rotating plate; As a further description of the above technical solution: The tension adjustment mechanism includes a frame, a fixed shaft is fixedly connected inside the frame, a strap is fixedly connected outside the fixed shaft, an adjustment frame is fixedly connected to the other end of the strap, rotating rods are rotatably connected to the left and right sides inside the adjustment frame, an extension band is slidably connected to the outside of the rotating rods, and a locking rod is fixedly connected to the outside of the extension band. As a further description of the above technical solution: The bottom of the support frame is fixedly connected to a longitudinal support rod, and a placement box is fixedly connected to one of the two longitudinal support rods on the adjacent side. As a further description of the above technical solution: The support frame is fixedly connected to the outside with a rubber sleeve, and the fixing rod is slidably connected to the inside of the support frame. As a further description of the above technical solution: The fixed rod has multiple slots on its outside, and the outside of the fixed rod engages with the outside of the slots. As a further description of the above technical solution: The external rotating plate is rotatably connected to the inside of the mounting frame, and the external rotating rod is rotatably connected to the inside of the mounting frame; As a further description of the above technical solution: One end of the spring is fixedly connected to the outside of the support frame, and the other end of the spring is fixedly connected to the outside of the rotating plate.

[0007] This utility model has the following beneficial effects: 1. In this utility model, pressing the rotating plate compresses the telescopic rod, causing the spring to deform. This causes the rotating plate to separate the rod from the slot on the outside of the fixed rod. When adjusted to the appropriate position, releasing the rotating plate allows the spring to rebound, engaging the rod with the slot on the outside of the fixed rod. This allows for adjustment of the fixed rod's position. By adjusting the height of the fixed rod, patients of different heights can find the most suitable grip position. For example, tall patients can raise the fixed rod, while shorter patients can lower it, allowing them to maintain a natural and comfortable posture when using the walking aid.

[0008] 2. In this utility model, when adjusting the tightness of the strap, the locking rod is pulled out. By pulling out the locking rod, the extension strap can be tightened or loosened. When the extension strap is adjusted to a comfortable position, the locking rod is inserted to fix the extension strap inside the strap, thereby realizing the adjustment of the tightness of the strap. The adjustable strap allows the patient to adjust the strap to a suitable tightness according to their own feelings, so that the pressure is evenly distributed on the body, effectively relieving local pressure and improving the comfort of wearing it.
