Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional rehabilitation walking aid. Background Technology

[0002] In the field of medical rehabilitation, rehabilitation walking aids are crucial assistive tools for patients whose walking ability is limited due to leg or lumbar fractures or other surgeries. Rehabilitation walking aids are medical assistive devices primarily used to help patients with lower limb dysfunction undergo rehabilitation training and improve their walking ability. They provide additional support and balance, helping patients reduce the burden on their legs and improve their walking capacity. Patients with limited mobility generally need to undergo a long-term rehabilitation process, which may last for days, months, or even years. During the rehabilitation process, a well-designed, easy-to-use, fully functional, and comfortable walking aid has a significant impact on improving the user's quality of life and rehabilitation outcomes. In addition, rehabilitation walking aids are also indispensable assistive tools for older adults with unstable walking habits. For example, elderly people can use rehabilitation walking aids for daily activities such as walking and toileting, assisting them in walking safely and preventing falls and other accidents.

[0003] However, current rehabilitation or mobility aids have some shortcomings. For example, common underarm rehabilitation canes lack a self-supporting frame design, requiring them to lean against a wall or other support when not in use, which is inconvenient for users when they need to stop walking or sit down temporarily. Furthermore, the canes are bulky, making them inconvenient to store and carry when users are out. At night or in low-light conditions, users need to hold the canes with both hands, preventing them from using flashlights or other lighting devices, increasing the risk of falls.

[0004] In summary, although underarm rehabilitation crutches offer strong support and stability, with features such as triangular stabilizing support, adjustable height, and anti-slip cushioning, several issues remain to be addressed, including reliance on temporary placement, inconvenience in carrying, and safety concerns during nighttime walking. Therefore, designing and developing a more comfortable and functional rehabilitation walking aid is particularly important.

[0005] CN218853055U discloses a walking aid with an adjustable cane, including a support rod, anti-slip sleeves on the bottom of the feet, slots on the upper surface of the support rod, a fixing seat at the bottom of the vertical rod, a rod inserted at the bottom of the fixing seat corresponding to the slot, a battery box in the mounting slot, lamp holders in the slots, and lights on the lamp holders, a handle on the vertical rod, and a bracket device at the end of the handle. A threaded groove communicating with the slot is formed near the top of the outer wall of the support rod, and a fastening bolt is installed in the threaded groove. This walking aid with an adjustable cane increases the friction with the ground by setting multiple feet and using anti-slip sleeves, thereby improving the overall stability of the support. The lamp holder and lights installed on the fixing seat provide continuous illumination around the support rod with the help of the battery box and dry batteries. The rubber sleeves on the handles increase the friction with the user's hand, making it easier to hold and use.

[0006] The walking aid in this technical solution increases friction between the walker and the ground by configuring multiple paws and incorporating anti-slip sleeves, thereby improving overall stability. However, the fixed four paws in this design may present some potential problems in actual use, especially when walking on uneven surfaces. Because the grip is relatively fixed, it's difficult for the user to adjust the support points according to road conditions, resulting in one or more paws bearing greater pressure and experiencing higher wear. This uneven wear not only affects the overall stability and lifespan of the walking aid but may also prevent it from standing stably on its own using only the four paws when idle. Therefore, users may need to lean the walking aid against a wall or lay it flat on the ground, which not only increases space usage but can also cause inconvenience.

[0007] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

[0008] In view of the shortcomings of the prior art, this application proposes a multifunctional rehabilitation walking aid, which aims to solve one or more technical problems in the prior art.

[0009] This utility model relates to a multifunctional rehabilitation walking aid, including an upper support part for supporting the body and a lower support part for supporting the ground. The upper support part includes a first rod and a second rod that are nested together. The rehabilitation walking aid can switch between underarm support and hand support modes by selectively installing the first rod onto or removing it from the second rod. The lower support part includes a third rod and a fourth rod that are nested together. The periphery of the fourth rod is designed with several uprights that can be unfolded and retracted. Under mechanical or manual drive, the upper end of the uprights is connected to the top of the fourth rod and can rotate. The lower end of the uprights supports the ground in a way that assists the bottom end of the fourth rod.

[0010] This utility model of a rehabilitation walking aid features an interlocking design between the first and second rods of the upper support section, allowing different users to easily switch between underarm and hand support according to their support needs and usage requirements. The detachable design of the upper support section allows users to adjust it according to their height and comfort, ensuring personalized use and improving user comfort. The interlocking structure of the third and fourth rods of the lower support section ensures stable bottom support, enhancing the stability of the walking aid during use. The fourth rod has several extendable and retractable supports on its circumference, enabling the walking aid to adapt to different ground conditions and usage scenarios. For example, when temporary placement of the walking aid is needed, the supports can be extended to ensure stable support. Furthermore, the mechanical or manual drive design of the supports makes the extension and retraction of the supports simple and convenient, allowing users to easily master the operation, even those who are physically weak, have limited strength, or have mobility issues.

[0011] According to a preferred embodiment, the upper support and lower support are connected by a connecting rod, wherein a second rod is fixedly connected to the top surface of the connecting rod, and a third rod is detachably connected to the bottom surface of the connecting rod. The fixed connection of the second rod to the top surface of the connecting rod provides a stable upper structure, ensuring the stability of the upper support during use. The detachable connection of the third rod allows the user to quickly adjust the height of the lower support as needed to accommodate different user heights or usage scenarios. Because the third rod is detachable, the user can easily remove the lower support when maintenance or storage is required, reducing maintenance costs and improving ease of use. When the third rod is removed, the overall size of the walker is reduced, making it easier to store or carry, thus improving the walker's portability.

[0012] According to a preferred embodiment, the upper support includes an underarm support end and a hand grip support end.

The design of the underarm support end and the hand grip support end takes ergonomic principles into account, providing a shape and curvature adapted to the user's underarms and hands, ensuring comfort and effective support. The underarm support end, located at the top of the first bars, provides a high-position support design that helps distribute the user's weight, reduces pressure on the underarms, and provides a stable support point. The hand grip support end, located on the inner surface of the second bars, facilitates a natural grip and provides an easy-to-hold handle, making the walker more convenient and comfortable to use. The paired first and second bars provide a wider support area, increasing the stability of the walker and reducing the risk of falls due to instability while walking.

[0013] According to a preferred embodiment, the surface of the handgrip support end is equipped with several buttons, which are connected via electrical wires to a heater built into the handgrip support end, a light source located on the side of the connecting rod, and an alarm located within the connecting rod. The heater built into the handgrip support end can keep the user's hands warm when the outside temperature is low, increasing comfort when holding the handgrip, especially in winter or cold environments. The light source located on the side of the connecting rod can provide illumination in low-light environments, increasing visibility while walking at night and reducing the risk of falls. Furthermore, in the event of a fall or other accident, the user can use the alarm to sound an alarm, attracting the attention of those nearby. The buttons are located on the surface of the handgrip support end; the user can activate the corresponding function by pressing and holding the button (to avoid accidental activation), making operation convenient.

[0014] According to a preferred embodiment, the bottom end of the fourth pole is equipped with a detachable base. The bottom surface of the base in contact with the ground has a threaded design, and a shock-absorbing spring is disposed between the base and the fourth pole. The detachable base design allows the user to quickly replace the worn base without replacing the entire fourth pole, reducing maintenance costs and time. The threaded design of the base increases friction with the ground, improving stability and maintaining stability on both smooth and rough surfaces. The shock-absorbing spring between the base and the fourth pole effectively reduces the impact and vibration generated during walking, alleviating pressure on the user's joints and muscles and improving user comfort.

[0015] According to a preferred embodiment, the surfaces of the second and third rods are provided with a plurality of adjustment holes along their respective extension directions, and the surfaces of the first and fourth rods are provided with positioning elements that correspond to the adjustment holes. The positioning elements can change the height of the upper and lower support sections by corresponding to different adjustment holes. Users can adjust the height of the upper and lower support sections of the walker according to their individual height or usage needs by selecting different adjustment holes, achieving a personalized user experience. The matching design of the positioning elements and adjustment holes allows users to adjust the height without tools, providing a simple and quick adjustment method. By adjusting the height of the upper and lower support sections, the walker can meet the body proportions and usage needs of different users, increasing its versatility.

[0016] According to a preferred embodiment, the bottom surface of the connecting rod is designed with a mounting groove with internal threads. The third rod can be detachably connected to the connecting rod by screwing in and out of the external thread at its top through the internal thread of the mounting groove. The pre-designed internal thread mounting groove allows the third rod to be quickly screwed in or out via the external thread, facilitating the user's assembly and disassembly of the walking aid and improving ease of use. The tight engagement of the internal and external threads provides a robust connection, ensuring the structural stability of the walking aid during use. Furthermore, when the third rod is removed, the overall size of the walking aid is reduced, making it easier to store or carry.

[0017] According to a preferred embodiment, the handgrip support end is designed with a battery compartment to house the power supply connected to the heater, light, and alarm via electrical wires. The integrated design of the battery compartment allows the power unit to be placed within the handgrip support end for easy management and maintenance. The battery compartment is designed to be concealed, not affecting the walker's appearance, while ensuring both functionality and aesthetics.

[0018] According to a preferred embodiment, the outer layer of the underarm support end is covered with a silicone protective pad to relieve pressure on the underarm skin. The silicone protective pad, due to its softness, reduces pressure on the underarm skin, nerves, and blood vessels, providing more comfortable support and reducing discomfort that may occur with prolonged use. The smooth surface of the silicone material reduces friction between the walker and the user's underarm skin, lowering the risk of skin damage. Furthermore, silicone has some water-absorbing properties, helping to absorb sweat generated during use, keeping the skin dry and improving user comfort. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] Preferably, such as Figure 1 As shown, this utility model relates to a multifunctional rehabilitation walking aid, including an upper support part 100 for supporting the body and a lower support part 200 for supporting the ground. The upper support part 100 includes a first rod 110 and a second rod 120 that are nested together, and the lower support part 200 includes a third rod 210 and a fourth rod 220 that are nested together. The first rod 110 and the fourth rod 220 can be adjusted to insert into the second rod 120 and the third rod 210 respectively, so that the rehabilitation walking aid can adapt to the arm length and height of different users.

[0029] Preferably, such as Figure 1As shown, the outer diameter of the first rod 110 is slightly smaller than the inner diameter of the second rod 120, so that the first rod 110 can be inserted into the interior of the second rod 120, and the insertion depth can be flexibly adjusted. The first rod 110 and the second rod 120 are arranged in pairs, that is, the upper support portion 100 includes two parallel first rods 110 and two parallel second rods 120. The outer diameter of the fourth rod 220 is slightly smaller than the inner diameter of the second rod 120, so that the fourth rod 220 can be inserted into the interior of the third rod 210, and the insertion depth can be flexibly adjusted. Preferably, the surfaces of the second rod 120 and the third rod 210 are provided with a plurality of equidistantly distributed adjustment holes along their respective rod extension directions, and the surfaces of the first rod 110 and the fourth rod 220 are provided with positioning members that correspond to the adjustment holes. The positioning members can adjust the height of the upper support portion 100 and the lower support portion 200 by corresponding to different adjustment holes. For easy and quick adjustment, the positioning element can be designed with a spring clip or a quick-release button. The user simply presses the release button to quickly release the positioning element, adjusts it to the appropriate height, and then releases the release button again, causing the positioning element to spring up and enter the corresponding adjustment hole and lock in place.

[0030] Preferably, such as Figure 1 , Figure 2 As shown, a connecting rod 150 is disposed between the upper support portion 100 and the lower support portion 200. The connecting rod 150 serves as the connecting part between the upper support portion 100 and the lower support portion 200. Its top surface is fixedly connected to the second rod body 120, while its bottom surface is detachably connected to the third rod body 210, ensuring the stability and adjustability of the walking aid. When the walking aid needs to be stored, the user can quickly remove the third rod body 210, reducing the overall height of the walking aid and making it easier to carry and store. In situations with limited space, the detachable third rod body 210 allows the walking aid to occupy less space when not in use, thereby improving space utilization efficiency. Furthermore, removing the third rod body 210 makes it easier to clean various parts of the walking aid, especially the lower support portion 200, which helps with cleaning and extends the lifespan of the walking aid.

[0031] Preferably, such as Figure 1As shown, the upper support portion 100 is equipped with an underarm support end 130 and a hand grip support end 140. The underarm support end 130 is located at the top of two paired first rods 110, and its shape can be designed according to the curve of the human underarm to ensure sufficient support for the user's underarm while minimizing pressure on the underarm skin, nerves, and blood vessels. Simultaneously, the outer layer of the underarm support end 130 is covered with a silicone protective pad, which has good elasticity and breathability. This protective pad not only reduces pressure under the armpit but also provides comfort and protects the skin. The hand grip support end 140 is located on the opposing inner surfaces of two paired second rods 120, and its design features an ergonomic handle shape to adapt to different users' hand shapes and grip needs, ensuring a stable and comfortable grip experience. The handle surface can be made of non-slip material or texture to increase friction and maintain a good grip even when hands are sweaty or slippery.

[0032] Preferably, such as Figure 2 , Figure 3 As shown, the rehabilitation walking aid of this invention can switch between an underarm support mode and a hand support mode by attaching or removing the first rod 110 from the second rod 120. In the underarm support mode, the first rod 110 and the second rod 120 are simultaneously mounted on the upper support part 100. In this mode, the user supports their entire body weight using the underarm support end 130, suitable for users with leg or lower back injuries who require prolonged use. In the hand support mode, the first rod 110 in the upper support part 100 is removed, leaving only the second rod 120. In this mode, the rehabilitation walking aid transforms into a handheld cane, with the user supporting their body by gripping the support end 140. This mode is suitable for users with minor leg injuries or the elderly and frail who need short-distance walking.

[0033] Preferably, such as Figure 4As shown, the surface of the grip support end 140, which takes the form of a handle, is equipped with several buttons to control the heater built into the grip support end 140, the light 151 located on the side of the connecting rod 150, and the alarm built into the connecting rod 150, respectively. The buttons are arranged in easily accessible locations on the grip support end 140, such as the side of the grip portion, so that the user can easily operate them while using the walker. Each button has a clear label, such as using a diagram, symbol, or text, to indicate its corresponding function (heater, alarm, or light). The user activates the corresponding function by pressing and holding the button (to avoid accidental activation). In particular, the labels on the buttons can also have a backlight or luminous function for easy identification in low-light or nighttime use. The alarm can be a buzzer, which sounds when the user presses the corresponding button. The buzzer's horn is positioned on the top surface of the connecting rod 150. This design prevents the horn from being blocked by the ground when the walker falls, ensuring a timely alarm in emergencies to attract the attention of those nearby. The lighting 151 is positioned on the side of the connecting rod 150, rather than the side of the handgrip support 140, to ensure its illumination covers the area in front of the user, preventing the light from being blocked by the user's hand or the walker's body, thus expanding the illumination range. Considering the walker may be used in humid environments, the buttons and surrounding area are waterproof to prevent moisture from seeping into the walker and affecting its normal function.

[0034] Preferably, to ensure the functionality of the walker, a battery compartment is designed inside the hand grip support end 140 to house the power supply for the heater, alarm and light 151, ensuring the continuous operation of the walker.

[0035] Preferably, such as Figure 5As shown, the fourth rod 220 has several extendable and retractable supports 240 arranged on its circumference. Driven mechanically or manually, the upper end of each support 240 is connected to the top of the fourth rod 220 and can rotate. The lower end of each support 240 assists the bottom of the fourth rod 220 in supporting the ground. The extended supports 240 provide a stable support structure at the bottom of the rehabilitation walker, ensuring that the walker can stand upright on the ground independently when not in use, without needing to lean against a wall or object. The supports 240 can be designed as a flip-up structure, with the top of each support 240 connected to the fourth rod 220 via a hinge. The hinges should have sufficient strength and durability to support the repetitive movement of the supports 240 during extension and retraction. The materials used for the supports 240 should be lightweight and have high rigidity to reduce overall weight and improve stability. To ensure that the stand 240 can stably support the walker after unfolding, the unfolding angles of multiple stands 240 can be kept consistent. The hinges can limit the unfolding angle of the stands 240 by using built-in locking pins. When the stand 240 rotates to the desired angle, the locking pins automatically slide into specific grooves in the hinges, locking the stand 240 and preventing further rotation. At this point, the bottom ends of each stand 240 are on the same plane for contact with the ground. Specifically, in addition to the stand 240 being manually unfolded and retracted by the user, the support end 140 can also be held (e.g., ...). Figure 4 The unit (as shown) can also be equipped with a miniature motor. The output of this motor is connected to the stand 240. By pressing a button on the handgrip support end 140, the user can use electricity to drive the hinge structure at the top of the stand 240 to rotate, thus easily and quickly controlling the unfolding and retraction of the stand 240 (as shown). Figure 5 and Figure 6 (As shown).

[0036] Preferably, such as Figure 5As shown, the bottom end of the fourth rod 220 is equipped with a detachable base 230. The bottom surface of the base 230 in contact with the ground is threaded, and a shock-absorbing spring is installed between the base 230 and the fourth rod 220. The base 230 is connected to the fourth rod 220 via a quick-release mechanism, such as a screw thread, snap-fit, or quick-release button. This design allows the user to quickly replace a worn base 230 or perform cleaning when needed, without replacing the entire fourth rod 220. The threaded design of the base 230 in contact with the ground increases friction and provides good anti-slip properties. The shock-absorbing spring between the base 230 and the fourth rod 220 acts as a buffer, cushioning the impact of walking, reducing vibration to the user's joints, and improving walking comfort. The base 230 should be made of a material with good wear resistance and impact resistance; high-strength plastic or metal is typically chosen, and wear-resistant rubber or silicone pads are added to the surface in contact with the ground to improve durability and anti-slip properties. Furthermore, the detachable connection between the base 230 and the fourth pole 220 facilitates replacement when the base 230 is severely worn. Specifically, when the stand 240 is folded up, the walker contacts the ground via the base 230, and when the stand 240 is unfolded, the bottom of the stand 240 extends beyond the bottom of the fourth pole 220 to assist the base 230 in supporting the ground.

[0037] Preferably, the bottom surface of the connecting rod 150 is designed with an internally threaded mounting groove, which can be screwed into the external thread at the top of the third rod 210. This design not only ensures the stability and reliability of the connection, but also provides a simple assembly and disassembly process through precise thread engagement. When the walker needs to be used, assembly can be quickly completed by simply screwing the third rod 210 into the internally threaded mounting groove of the connecting rod 150. To ensure the sealing stability of the connection under stress, the threaded connection is equipped with an efficient locking mechanism, such as a spring washer or a lock nut, to prevent accidental loosening during walking. When the walker is not in use, the third rod 210 can be easily unscrewed from the connecting rod 150, thereby reducing the overall size of the walker and making it easy to store and carry. This design is particularly suitable for homes, hospitals, or other places where the walker needs to be temporarily placed, ensuring that the walker does not occupy too much space when not in use, while also being easy to carry.
