Abstract
Description
Technical Field
[0001] This utility model relates to the field of orthopedic nursing technology, specifically to an orthopedic nursing walking aid. Background Technology
[0002] A walking aid, also known as a lower limb orthosis, is a walking support tool used by elderly people with mobility difficulties, certain injured patients, hemiplegic patients, and disabled people. It helps the body support weight, maintain balance, and practice walking. Instructions for using a walking aid: Before using the walking aid, first check that all the foot pads are in stable contact with the ground and that the positioning pins are fixed. When using the walking aid, avoid leaning too far forward or backward, and pay attention to maintaining balance. When moving forward or pushing the walking aid, the walking aid should not be too far from the user. When taking a step, the legs should not be too close to the walking aid. When using a wheeled walking aid, pay attention to the walking speed; do not go too fast. Avoid wearing slippers that are easy to slip off or shoes with heels. Do not use it on slopes, stairs, or uneven ground.
[0003] In the current technology, after orthopedic surgery, patients need rehabilitation care and use orthopedic nursing walkers to assist walking, reduce the occurrence of complications, and promote physical recovery. However, when adjusting the height of the existing nursing walkers, it is necessary to adjust each of the four legs of the nursing walker to the same height one by one, which is relatively troublesome. If no one is present, it is inconvenient for the patient to adjust it by himself.
[0004] Therefore, an orthopedic nursing walking aid is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide an orthopedic nursing walking aid in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] An orthopedic nursing walking aid includes four vertical bars, two horizontal bars on each of the four vertical bars, a fixed plate on each of the four vertical bars, two U-shaped plates on each of the four vertical bars, and a height-adjusting lifting mechanism on each of the four vertical bars, which is mounted on the fixed plate and inside the U-shaped plate. The bottom of the lifting mechanism has a buffer mechanism to reduce the impact caused by rigid contact with the ground. A storage box is provided on the fixed plate. The lifting mechanism includes two limiting bidirectional lead screws, which are rotatably mounted on the four vertical bars and are located inside the U-shaped plate. Two connecting rods are threaded onto the outer wall of each of the two limiting bidirectional lead screws. The system comprises four connecting plates that are slidably mounted on the inner walls of two U-shaped plates. Each of the four connecting plates is rotatably mounted with a double-ring rod. Each of the four vertical rods has a rectangular hole on its side. Each of the four vertical rods has a hollow column slidably mounted on its inner wall. Two sliding plates are mounted on the four hollow columns, slidably mounted on the inner walls of the rectangular holes. The four double-ring rods are rotatably mounted on the two sliding plates. The rear ends of the two limiting bidirectional lead screws extend beyond the rear vertical rods. Gear 1 is mounted on the surface of each of the two extended ends of the limiting bidirectional lead screws. A cross cylinder is rotatably mounted on the fixed plate. Gear 2 is mounted on the rear side of the cross cylinder. Gear 2 and the two gears 1 have meshing toothed belts on their outer walls. A torsion handle is mounted on the front side of the cross cylinder.
[0008] Furthermore, a protective shell is installed on the rear side of the fixing plate, and the protective shell is installed on the surface of the two rear vertical rods. Gear 1, Gear 2 and the toothed belt are arranged inside the protective shell.
[0009] Furthermore, the buffer mechanism includes four limiting plates, which are installed on the inner wall of the hollow columns. Each of the four hollow columns has a sliding hole through its bottom. Each of the four limiting plates has a buffer spring at its bottom. Each of the four sliding holes has a sliding post slidably installed on its inner wall. The sliding post is slidably installed between the limiting plate and the hollow column and is in contact with the buffer spring. Each of the four sliding posts has a base installed at its bottom.
[0010] Furthermore, each of the four bases is equipped with an anti-slip pad, and the anti-slip pad is made of rubber.
[0011] The beneficial effects of this utility model are as follows:
[0012] This invention utilizes a combination of limiting bidirectional lead screws, double ring rods, and hollow columns. By rotating a torsion handle, the cross cylinder rotates, causing gear two to rotate as well. The toothed belt serves as the linkage hub between gear one and gear two, ensuring their synchronous rotation. The two limiting bidirectional lead screws rotate accordingly, causing four connecting plates to slide closer to each other within two U-shaped plates, with two plates corresponding to each other. The four double ring rods change angles, pushing two sliding plates downwards within four rectangular holes. The hollow column, connected to the four sliding plates, slides downwards within four vertical rods. This allows for adjustment based on the height of different patients and their comfort level, making the operation convenient and simple to use.
[0013] This invention, through the setting of buffer springs, sliding columns, and bases, allows the patient to lift the entire unit by holding the two horizontal bars with both hands and then lower it forward. When lowering, the base makes rigid contact with the ground, causing the sliding column to slide between the sliding hole, the limiting plate, and the hollow column, compressing the buffer spring. The buffer spring reduces and absorbs the impact force, thereby enhancing the patient's comfort. Attached Figure Description

[0024] like Figure 1-3As shown, an orthopedic nursing walking aid includes four vertical rods 1, two horizontal rods 2 on each of the four vertical rods 1, a fixed plate 3 on each of the four vertical rods 1, two U-shaped plates 5 on each of the four vertical rods 1, and a height adjustment mechanism 6 on each of the four vertical rods 1. The height adjustment mechanism 6 is mounted on the fixed plate 3 and is located inside the U-shaped plate 5. A buffer mechanism 7 is provided at the bottom of the height adjustment mechanism 6 to reduce the impact caused by rigid contact with the ground. A storage box 4 is provided on the fixed plate 3. The height adjustment mechanism 6 includes two limiting bidirectional screw rods 601, which are rotatably mounted on the four vertical rods 1 and are located inside the U-shaped plate 5. Two connecting plates 602 are threadedly installed on the outer wall of each of the four vertical rods 1. The four connecting plates 602 are slidably installed on the inner walls of the two U-shaped plates 5. Double ring rods 603 are rotatably installed on each of the four connecting plates 602. Rectangular holes 605 are opened on the sides of each of the four vertical rods 1. Hollow columns 606 are slidably installed on the inner walls of the four vertical rods 1. Two sliding plates 604 are installed on the four hollow columns 606. The sliding plates 604 are slidably installed on the inner walls of the rectangular holes 605. The four double ring rods 603 are rotatably installed on the two sliding plates 604. The rear ends of the two limiting bidirectional screw rods 601 extend to the outside of the rear vertical rod 1. Gears 607 are installed on the surface of the two extended ends of the limiting bidirectional screw rods 601. A cross cylinder 609 is rotatably installed on the fixing plate 3. A gear 608 is installed on the rear side of column 609. Gear 608 and two gears 607 are meshed with toothed belts 611 on their outer walls. A torsion handle 610 is installed on the front side of the cross-shaped column 609. In this embodiment, during use, the overall height is first adjusted according to the patient's height using the lifting mechanism 6 to suit the patient's height. The patient holds the two horizontal bars 2 with both hands, lifts the entire structure, and then lowers it forward. When lowering, the buffer mechanism 7 reduces the impact force generated by rigid contact with the ground, enhancing the patient's comfort. Then, the patient walks forward according to their position to perform rehabilitation training. During training, items such as mobile phones and water cups can be placed in the storage box 4 for easy access, thus allowing for adjustments based on the patient's height. The height is adjustable for comfort, making operation convenient and simple. This reduces the impact of rigid contact with the ground, enhancing user comfort. Two rotating limit screws 601 drive four connecting plates 602 to slide closer together within two U-shaped plates 5, with two plates corresponding to each other. The four double-ring rods 603 change angle, pushing two sliding plates 604 downwards within four rectangular holes 605. The hollow column 606 connected to the four sliding plates 604 slides downwards within four vertical rods 1, thus adjusting the height of the vertical rods 1. Rotating the torsion handle 610 drives the cross cylinder 609 to rotate, causing gear two 608 to rotate accordingly. The toothed belt 611 serves as the linkage center for gear one 607 and gear two 608, ensuring their synchronous rotation.The two limiting bidirectional lead screws 601 rotate accordingly, thus providing convenient rotation for the two limiting bidirectional lead screws 601.
[0025] like Figure 2 As shown, a protective shell 612 is installed on the rear side of the fixing plate 3. The protective shell 612 is installed on the surface of the two rear vertical rods 1. Gear 1 607, gear 2 608 and toothed belt 611 are arranged inside the protective shell 612. In this embodiment, the protective shell 612 covers gear 1 607, gear 2 608 and toothed belt 611, which enhances safety and improves aesthetics.
[0026] like Figure 1 , Figure 4 As shown, the buffer mechanism 7 includes four limiting plates 701, which are installed on the inner wall of the hollow column 606. Each of the four hollow columns 606 has a sliding hole at its bottom, and each of the four limiting plates 701 has a buffer spring 702 at its bottom. Each of the four sliding holes has a sliding column 703 slidably installed on its inner wall. The sliding column 703 is slidably installed between the limiting plate 701 and the hollow column 606, and it contacts the buffer spring 702. Each of the four sliding columns 703 has a base 704 installed at its bottom. In this embodiment, when the base 704 is in rigid contact with the ground, the sliding column 703 will slide between the sliding hole and the limiting plate 701 and the hollow column 606, compressing the buffer spring 702. The buffer spring 702 reduces and absorbs the impact force, thereby enhancing the patient's comfort.
[0027] like Figure 4 As shown, the bottom of each of the four bases 704 is equipped with an anti-slip pad 705, and the anti-slip pad 705 is made of rubber. In this embodiment, the rubber anti-slip pad 705 can enhance the frictional resistance with the ground and improve stability.
[0028] In summary, during use, the overall height is first adjusted according to the patient's height using the lifting mechanism 6 to suit their needs. The patient holds the two horizontal bars 2 with both hands, lifts the entire unit, and then lowers it forward. During this lowering, the buffer mechanism 7 reduces the impact force generated by the rigid contact with the ground, enhancing the patient's comfort. The patient then moves forward to perform rehabilitation training. Items such as mobile phones and water cups can be placed in the storage box 4 for easy access. This allows for adjustment based on different patients' heights and comfort levels, making operation convenient and simple. The two rotating limit bidirectional screws 601 drive the four connecting plates 602 to slide closer together within the two U-shaped plates 5, with two plates corresponding to each other. The four double-ring rods 603 change angles, pushing the two sliding plates 604 downward within the four rectangular holes 605. The hollow column 606 connected to plate 604 slides downward within the four vertical rods 1, thereby adjusting the height of the vertical rods 1. By rotating the torsion handle 610, the cross cylinder 609 rotates, and the second gear 608 rotates accordingly. The toothed belt 611 is the linkage center of the two gears 607 and 608, making them rotate synchronously. The two limiting bidirectional lead screws 601 rotate accordingly, thus providing convenient rotation for the two limiting bidirectional lead screws 601. The protective shell 612 covers the gears 607, 608, and toothed belt 611, enhancing safety and improving aesthetics. When the base 704 is in rigid contact with the ground, the sliding column 703 slides between the sliding hole and the limiting plate 701 and the hollow column 606, compressing the buffer spring 702. The buffer spring 702 reduces and absorbs the impact force, thereby enhancing the patient's comfort. The rubber anti-slip pad 705 enhances the frictional resistance with the ground and improves stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
