Abstract
Description
Technical Field
[0001] This application falls under the field of medical care, specifically relating to adjustable ergonomic lower limb pads. Background Technology
[0002] Lower limb pads are ergonomically designed assistive devices that typically feature an adjustable structure that conforms to the curves of the lower limbs. By elevating and supporting the lower limbs, they help patients during postoperative recovery, prolonged bed rest, or treatment by promoting venous return, reducing swelling, and preventing problems such as foot drop, pressure injuries, and lower limb venous thrombosis. They combine medical care and ergonomic features to provide comfortable and functional support for the lower limbs.
[0003] Most lower limb pads on the market are fixed, non-adjustable support pads. The height and length are adjusted by replacing different models of lower limb pads. This results in a large space required for storage and makes the replacement process inconvenient. Some self-adjustable lower limb pads are electrically adjusted via internal threaded rods, but this method increases the manufacturing cost of the lower limb pads, thereby increasing the usage cost for medical units. Utility Model Content
[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.
[0005] To address this, this application provides an adjustable ergonomic lower limb pad. The length is adjusted by sliding an adjusting block inside the outer shell, which in turn moves a telescopic square tube. Support legs are slidably connected to the bottom of the adjusting block and the sealing block, changing their support position as the adjusting block moves. A push-pull hole on the outer side of the sealing block assists in the sliding of the adjusting block. The outer shell and the sealing block are secured by a male-female snap fastener for easy storage. Grooves on both sides of the adjusting block accommodate internal components, and a top reinforcing strip enhances structural strength. A limiting strip and support fabric form a flexible support structure, with the limiting strip restricting the deformation range of the support fabric. When stored, the support fabric retracts into the groove; when in use, it is extended. A limiting hole at the bottom of the adjusting block engages with an elliptical limiting rod; rotating the limiting rod increases the friction with the limiting hole to lock it in place. The adjusting block can be slidably stored when rotated in the opposite direction. The limit buckle limits the connecting rod and ensures the rotation of the limit rod. The inner side of the shell has a height-increasing frame and a height-increasing support block to form a vertical adjustment structure. The toggle block and the scale groove cooperate to read the height. The bottom slide bar of the height-increasing frame is embedded in the slide groove of the height-increasing support block to ensure smooth sliding. The magnet on the outside of the inner slide bolt of the height-increasing frame attracts the iron piece of the height-increasing support block to form a magnetic lock. After adjusting the height, push the slide bolt, and the height-increasing support block is pushed to the position corresponding to the surface of the shell through the sliding connection of the slide bar and the slide groove. The outer tube end of the telescopic square tube is slidably connected to the adjusting block, and the other end is fixed to the outside of the adjusting block on the opposite side. When the two adjusting blocks slide towards each other or in opposite directions, the telescopic square tube drives the adjusting block to adjust the length through the relative sliding of the inner and outer tubes.

[0056] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0057] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.
[0058] In some embodiments, please refer to Figures 1 to 3 The adjustable ergonomic lower limb pad provided in this application includes: a shell 1; an adjustment mechanism 2, which is disposed inside the shell 1; a telescopic square tube 204, which is disposed inside the shell 1; an adjustment block 201, which is slidably connected to the inside of the shell 1; a closing block 202, which is disposed outside the adjustment block 201; and a support leg 225, which is slidably connected to the bottom inner side of the adjustment block 201 and the closing block 202.
[0059] In this embodiment, the adjusting block 201 slides inside the outer shell 1, thereby driving the telescopic square tube 204 to change its length and achieve length adjustment. The support leg 225 is slidably connected to the bottom of the adjusting block 201 and the closing block 202, which not only supports the overall structure, but also changes the support position as the adjusting block 201 moves, ensuring stability during adjustment. The push-pull hole 215 on the outside of the closing block 202 can assist in operating the sliding of the adjusting block 201. The outer shell 1 and the closing block 202 are fixed by the male buckle 214 and the female buckle 213, so that the closing block 202 and the adjusting block 201 can be easily folded up when no adjustment is needed.
[0060] In some embodiments, the adjusting block 201; the mounting groove 203 is formed on both sides of the adjusting block 201; the reinforcing strip 205 is disposed on the inner top of the mounting groove 203; and the limiting strip 206 is disposed inside the mounting groove 203 and is located at the bottom of the reinforcing strip 205.
[0061] Support cloth 207 is installed on the outside of the limiting strip 206 and is located inside the mounting groove 203; limiting hole 208 is opened at the bottom of the adjusting block 201.
[0062] In this embodiment, the placement grooves 203 on both sides of the adjusting block 201 are used to accommodate the internal components. The reinforcing strip 205 on the top enhances the structural strength and prevents deformation during adjustment. The limiting strip 206 and the support cloth 207 are combined to form a flexible support structure. The limiting strip 206 guides and limits the deformation range of the support cloth 207 with its own curvature. When the lower limb pad is stored, the support cloth 207 is retracted into the placement groove 203 when the adjusting blocks 201 are pressed together, preventing it from being trapped between the adjusting blocks 201. When in use, the adjusting blocks 201 are spread apart, and the support cloth 207 is spread apart by the limiting strip 206, so that the support cloth 207 is flattened and conforms to the curve of the patient's lower limb through deformation, providing support and comfort.
[0063] In some embodiments, a limiting hole 208 and a limiting rod 209 are provided inside the limiting hole 208.
[0064] In this embodiment, the bottom limiting hole 208 cooperates with the limiting rod 209 to lock the position of the adjusting block 201. When the limiting rod 209 is rotated within the limiting hole 208, the elliptical limiting rod 209 will hold the limiting hole 208 in place. By increasing the friction between the limiting rod 209 and the limiting hole 208, the adjusting block 201 is fixed, preventing the adjusting block 201 from accidentally sliding due to external force after adjustment. Conversely, when the limiting rod 209 is rotated back to its original position, the adjusting block 201 can slide freely into the outer shell 1 for storage.
[0065] In some embodiments, a limiting rod 209; a connecting rotating rod 211, the connecting rotating rod 211 being installed at one end of the limiting rod 209; a limiting buckle 210, the limiting buckle 210 being rotatably connected to the outside of one end of the connecting rotating rod 211, the limiting buckle 210 being installed on the outside of the closing block 202; and a toggle rod 212, the toggle rod 212 being installed at the top of the limiting rod 209.
[0066] In this embodiment, the limiting buckle 210 limits the connecting rotating rod 211 to prevent it from dislodging. The limiting buckle 210 ensures the normal operation of the limiting rod 209 by rotating with the connecting rotating rod 211.
[0067] In some embodiments, the enclosure block 202 includes a push-pull hole 215, which is located on the outside of the enclosure block 202; and a female buckle 213, which is installed on the outside of the enclosure block 202.
[0068] In this embodiment, a tool can be inserted into the push-pull hole 215 on the outside of the sealing block 202 to directly push the adjusting block 201 to slide inside the outer shell 1, facilitating precise control of the adjustment range. When the female buckle 213 engages with the male buckle 214 on the outside of the outer shell 1, a tight connection is achieved through elastic deformation—after the male buckle 214 is inserted into the female buckle 213, its flange engages with the groove of the female buckle 213, preventing the outer shell 1 from separating from the sealing block 202, while allowing for quick assembly and disassembly.
[0069] In some embodiments, please refer to Figures 3 to 6 The outer shell 1; the heightening frame 216, which is slidably connected to the inner side of the outer shell 1; the heightening support block 224, which is slidably connected to the inner front side of the outer shell 1; and the scale groove 221, which is opened on the outer side of the outer shell 1.
[0070] In this embodiment, the height-increasing frame 216 and the height-increasing support block 224 on the inner side of the outer shell 1 constitute the vertical adjustment of the entire lower limb pad. The toggle block 220 slides in conjunction with the scale groove 221 on the outer side of the outer shell 1. The height position of the height-increasing frame 216 can be read intuitively through the scale of the scale groove 221. The slider 222 at the bottom of the height-increasing frame 216 is embedded in the slide groove 223 at the top of the height-increasing support block 224 to ensure the stability of horizontal sliding and avoid shaking.
[0071] In some embodiments, the heightening frame 216; the toggle block 220 is installed on the outside of the heightening frame 216; the slide 217 is opened on the inside of the heightening frame 216; and the slide bar 222 is installed at the bottom of the heightening frame 216.
[0072] In this embodiment, a sliding bolt 218 is provided in the slide 217 inside the height-increasing frame 216. The magnet 219 fixed on its outer side attracts the iron piece at the corresponding position of the height-increasing support block 224 to form a magnetic lock. When the lower limb pad is adjusting its height, the height-increasing support block 224 and the height-increasing frame 216 move downwards at the same time. When the height adjustment is completed, the sliding bolt 218 is pushed until the sliding bolt 218 contacts the iron piece.
[0073] In some embodiments, a slide rail 217; a sliding bolt 218, the sliding bolt 218 being slidably connected to the inner side of the slide rail 217; and a magnet 219, the magnet 219 being fixedly connected to the outer side of the sliding bolt 218.
[0074] In this embodiment, due to magnetic locking, the sliding bolt 218 and the height-increasing support block 224 are temporarily fixed together. At this time, if the sliding bolt 218 is pushed, the height-increasing support block 224 will be pushed outward through the sliding connection between the sliding strip 222 and the sliding groove 223 until the height-increasing support block 224 corresponds to the position of the outer shell 1, so as to achieve close support for the patient's thigh area and avoid gaps that affect the experience after the height of the lower limb pad is adjusted.
[0075] In some embodiments, the heightening support block 224; the slide 223 is mounted on the top of the heightening support block 224.
[0076] In this embodiment, the outer end of the square tube is slidably connected to the inside of the adjusting block 201, and the other end is fixed to the outside of the adjusting block 201 on the opposite side. When the two adjusting blocks 201 slide towards or away from each other in the outer shell 1, the telescopic square tube 204 changes its total length through the relative sliding of the inner and outer tubes, thereby driving the adjusting block 201 to adjust its length.
[0077] In some embodiments, the actuating block 220 is slidably connected to the scale groove 221, the heightening support block 224 is provided with iron plates at the corresponding positions of the magnet 219, the sliding groove 223 is slidably connected to the sliding strip 222, the outer tube end of the telescopic square tube 204 is slidably connected to the inside of the adjusting block 201, the other end of the telescopic square tube 204 is fixedly connected to another corresponding adjusting block 201, the outer side of the outer shell 1 is provided with a male buckle 214, the male buckle 214 is engaged with the female buckle 213, and the top surfaces of the adjusting block 201, the outer shell 1, the heightening support block 224, and the sealing block 202 that come into contact with the human body are made of breathable sponge material.
[0078] In this embodiment, the lower limb pad integrates functions such as telescopic adjustment, magnetic locking, and flexible support through a modular design of the mechanical structure. It not only meets the needs of lower limb elevation and body position fixation in clinical nursing, but also improves patient comfort through ergonomic optimization. Its multiple components work together to achieve and comply with the unity of functionality and safety of medical devices. The top part of the adjustment block 201, the outer shell 1, the heightening support block 224, and the sealing block 202 is made of breathable sponge material, which can adapt to the area that the patient touches and deform to increase the patient's comfort.
