Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a combined lower limb pad. Background Technology

[0002] Currently, in orthopedic clinical nursing, many patients who have suffered trauma, fractures, or lower limb surgery often require the use of lower limb pads to elevate their affected limbs during postoperative rehabilitation. As a basic and important assistive device, the main function of lower limb pads is to place the affected limb at a specific elevated angle and position. This measure is a crucial nursing technique for reducing limb tissue edema, preventing deep vein thrombosis, improving local blood circulation, and preventing complications such as foot drop. Elevating the affected limb effectively promotes venous and lymphatic return, playing a key role in controlling swelling, relieving pain, and accelerating fracture healing and wound recovery. Its application directly affects the patient's rehabilitation process and quality of life, thus having an undeniable positive impact on the overall rehabilitation process.

[0003] However, existing lower limb cushions have some significant design flaws that directly impact patient comfort and treatment outcomes. First, when placed on the bed, they tend to slide towards the foot of the bed due to changes in patient position or their own weight, deviating from the intended ideal support position. This not only reduces effectiveness but also increases the workload for caregivers who need repeated adjustments. Second, patients vary in body shape and required elevation, while most commercially available lower limb cushions are fixed sizes and lack adjustability, making them unsuitable for different body types and limiting their clinical applicability. Finally, during prolonged bed rest, patients' lower limbs often remain relatively still, lacking effective pressure relief and positional changes. This results in continuous pressure on the heels, obstructing local blood circulation and easily leading to pressure sores. This not only exacerbates patient suffering but also presents greater difficulties and challenges for subsequent care and rehabilitation. Utility Model Content

[0004] This invention aims to solve the problems existing in the prior art by providing a combined lower limb pad that can adjust the size of the pad according to the patient's needs. The pad is equipped with an inflatable or water-filled bladder corresponding to the area on the patient's heel where pressure sores are prone to occur, and an anti-slip layer is provided at the bottom of the pad to prevent overall displacement.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This combined lower limb pad includes a front pad that fits into the popliteal fossa of the patient's leg, a rear pad for supporting and elevating the patient's foot, a lateral adjustment part located between the front and rear pads and capable of adjusting the distance between the front and rear pads, a decompression part installed on the rear pad and corresponding to the calcaneus position of the patient's foot, and a longitudinal adjustment part that uses the lateral adjustment part to elevate the rear pad separately.

[0006] To further improve the design, the lateral adjustment section includes several detachably connected adjustment pads. The adjustment pads are detachably fixed to the front pad and the rear pad. The front pad and the rear pad have a horizontally oriented storage groove at one end near the adjustment pad. The adjustment pads can be inserted into the storage groove for storage along the horizontal direction.

[0007] In a further improvement, the adjusting pads are configured in multiple units and are detachably connected by snap fasteners. The adjusting pads are detachably connected to the front pad and the rear pad by Velcro.

[0008] As a further improvement, the longitudinal adjustment part includes a first heightening groove formed at the bottom of the rear pad block and capable of horizontally placing the adjustment pad, wherein the depth of the first heightening groove is less than the thickness of the adjustment pad.

[0009] Further improvements include a second heightening groove located at the bottom of the first heightening groove and capable of vertically placing the adjusting pad; the second heightening groove is perpendicular to the first heightening groove.

[0010] Further improvements include a pressure-reducing section comprising a soft bag that can be filled with gas or liquid, and a mounting groove located on the top of the rear pad for placing and positioning the soft bag.

[0011] Further improvements include a front pad with an inclined surface that supports the patient's thigh, and an arc surface on the inclined surface that matches the popliteal fossa of the patient's leg.

[0012] To further improve the design, the bottom of the front and rear pads is provided with an anti-slip layer to prevent slippage.

[0013] The beneficial effects of this invention are: it allows patients to be in a more natural and comfortable position, reduces muscle tension and joint discomfort caused by improper posture, effectively prevents pressure sores, reduces patient pain, and also reduces the pressure on medical staff to frequently turn over and examine the skin, as well as the cost of subsequent dressing changes. It ensures that the elevated lower limbs are always in the preset correct position, thus guaranteeing the effectiveness of treatment and nursing care. Attached Figure Description

Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] See attached document Figures 1-4 This embodiment of the combined lower limb pad mainly consists of two parts: a front pad 1 and a rear pad 2. The front pad 1 is designed to fit and support the patient's thigh and popliteal fossa area. Its upper part has an inclined plane 1-1, which effectively supports the thigh and reduces local pressure. Further on this inclined plane is an arc surface 1-2 adapted to the physiological curvature of the popliteal fossa, which avoids compression of nerves and blood vessels in the popliteal fossa, improving comfort and safety. The rear pad 2 is specifically designed to support and elevate the patient's foot, helping to promote blood flow back to the lower limbs and reduce pressure on the heel. To accommodate different limb lengths and body positions, a lateral adjustment section 3 is provided between the front pad 1 and the rear pad 2. This structure allows for flexible adjustment of the distance between the front and rear pads, thus better matching individual differences. In addition, the rear pad 2 also has a pressure-reducing section 4, which corresponds to the patient's calcaneal region. This section uses a cushioning or hollow design to effectively distribute force on the calcaneus and reduce the risk of pressure sores. To further enhance functional adaptability, this structure also includes a longitudinal adjustment part 5, which can be combined with the lateral adjustment part 3 to independently adjust the height of the rear pad 2 without moving the front pad, thereby achieving precise control of the foot elevation angle and adjusting to the most suitable pad height position. Finally, both the bottom of the front pad 1 and the rear pad 2 are covered with an anti-slip layer 6, which is made of a high friction coefficient material and can effectively prevent the pad from shifting during use, ensuring patient safety and stability.

[0018] See attached document Figures 1-4To meet the precise needs of different patients' leg lengths and clinical positioning, the lateral adjustment section 3 adopts a modular design. Specifically, the lateral adjustment section 3 includes several independent adjustment pads 3-1 of uniform thickness. These pads are detachably connected end-to-end via snap fasteners on the sides of the adjustment pads 3-1, allowing them to be assembled like building blocks into connection modules of different lengths. For easy storage, horizontally extending storage slots 3-2 are provided at the opposite ends of the front pad 1 and the rear pad 2. The size of the storage slots 3-2 allows a single adjustment pad 3-1 to be smoothly inserted or removed horizontally, achieving built-in storage of unused components and effectively preventing the loss of parts. In terms of fixing, the assembled adjustment pads 3-1 are glued to the front pad 1 and the rear pad 2 respectively using Velcro fasteners. In practice, medical staff can take out an appropriate number of adjustment pads 3-1 according to the patient's specific leg length, first splice them together into a whole using snap fasteners, and then firmly attach this assembly to the front pad 1 and the rear pad 2 using Velcro. By increasing or decreasing the number of adjustment pads 3-1, the distance between the front pad 1 and the rear pad 2 can be controlled, thereby providing the most suitable leg support for patients of different body types.

[0019] See attached document Figures 1-4 The longitudinal adjustment part 5 includes a first heightening groove 5-1 located at the bottom of the rear pad 2 and capable of horizontally placing an adjustment pad 3-1. The depth of the first heightening groove 5-1 is less than the thickness of the adjustment pad 3-1. When the adjustment pad 3-1 is horizontally placed into the first heightening groove 5-1, the first heightening groove 5-1 will raise the rear pad 2 by a certain distance to meet the height requirements of different patients. A second heightening groove 5-2 is also provided at the bottom of the first heightening groove 5-1. The second heightening groove 5-2 is perpendicular to the first heightening groove 5-1. The adjustment pad 3-1 can be vertically placed into the second heightening groove 5-2, which can also raise the rear pad 2. When the adjustment pad 3-1 is vertically placed into the second heightening groove 5-2, the distance that the rear pad 2 is raised is greater than when the adjustment pad 3-1 is horizontally placed into the first heightening groove 5-1. In this way, the height of the rear pad 2 can be adjusted by a single adjustment pad 3-1.

[0020] See attached document Figures 1-4 A mounting groove 4-2 is provided on the top of the rear pad 2. A soft pouch 4-1 is fixedly installed in the mounting groove 4-2. The soft pouch 4-1 can be filled with gas or liquid to adjust the degree of expansion and the degree of softness and hardness. The patient can adjust it to the most comfortable softness and hardness according to their own body feeling. The patient's heel bone area is placed on the soft pouch 4-1. Compared with ordinary hard pads, the soft pouch 4-1 has a much larger contact area with the patient's heel, which effectively disperses the pressure on this area, thereby avoiding the formation of pressure sores when the foot is elevated for a long time.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
