Description

Technical Field

[0001] This utility model relates to the field of medical devices and rehabilitation aids, specifically to a novel adjustable support footrest sponge pad. Background Technology

[0002] For patients who are bedridden for extended periods or require a sitting posture, especially those with neurological impairment, muscle weakness, or impaired consciousness, their feet are highly susceptible to deformities such as foot drop, inversion, and eversion due to their own weight, the pressure of bedding, or gravitational pull. Furthermore, continuous pressure on bony prominences like the heel can lead to pressure sores. These complications not only increase patient suffering and prolong recovery but also significantly increase the burden of medical care on families and society.

[0003] In existing technologies, simple pillows, blankets, or fixed foam pads are often placed under the patient's calves to elevate the feet. However, these methods have significant drawbacks: First, the shape of the support is not fixed, making it prone to displacement and unable to effectively and stably position the foot, making it difficult to maintain the foot in a functional position, i.e., a neutral position of approximately 90 degrees at the ankle joint; second, the height and angle of the support are not adjustable, failing to adapt to patients of different heights and body types or different lying / sitting angles, resulting in poor versatility; third, the support has poor breathability, and the fabric in contact with the foot may cause friction, increasing the risk of foot skin damage; finally, most simple supports lack targeted support for the arch of the foot, failing to effectively prevent foot deformities. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems by providing a novel adjustable support footrest sponge pad.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a novel adjustable support footrest sponge pad, comprising: The base plate has a rectangular plate-like structure; At least one support frame is fixedly mounted on one side of the base plate. The support frame is a telescopic structure, and one end of the support frame on the base plate is provided with a support foot. A foot support pad is fixedly installed on the side of the base plate away from the support frame. The side surface of the foot support pad facing away from the base plate has two U-shaped grooves for accommodating feet. The bottom surface of the U-shaped grooves is coplanar with the bottom surface of the foot support pad.

[0006] Furthermore, the base plate is made of wood, plastic, or rubber, and the perimeter of the base plate is provided with flexible edging.

[0007] Furthermore, the support feet support the support frame to other mechanisms.

[0008] Furthermore, the base plate has the same shape and projected area as the footrest pad.

[0009] Furthermore, it also includes a protective sleeve, which is fitted over the outside of the base plate, foot pad, and U-shaped groove.

[0010] The advantages of this invention compared to existing technologies are as follows: the front-to-back telescopic support frame allows for flexible adjustment of the support position, adapting to patients of different body types and ensuring the foot is always accurately supported; the unique U-shaped groove design stably fixes the foot in a functional position, effectively preventing foot drop and pressure sores; the protective sleeve and flexible edging enhance safety and comfort. The overall structure is simple and inexpensive, solving the core defects of existing support methods, such as inconvenient fixation, lack of fine-tuning, and susceptibility to complications. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] Figure 2 This is an exploded view of the structure of this utility model. Detailed Implementation

[0013] I. Working principle of this utility model: This invention utilizes a foot support pad 40 with specific U-shaped grooves 41 to achieve scientific support and pressure distribution for the human foot. When the patient's foot is placed on the foot support pad 40, the heels are respectively embedded in the corresponding U-shaped grooves 41, removing the heel, a bony prominence, from direct weight-bearing. Instead, the curved sidewalls of the U-shaped grooves 41 provide inclusive support, thereby dispersing the high pressure originally concentrated on the heel to areas with larger soft tissue areas such as the arch and the back of the calf, effectively reducing the risk of pressure sores. The structure of the U-shaped grooves 41 also serves as a natural restraint, preventing inversion or eversion of the foot and maintaining the ankle joint in a functionally neutral position.

[0014] To accommodate patients of different heights, the support frame 20 is designed to be adjustable in length and direction along the base plate 10. For patients with longer calves, the support frame 20 can be stretched outwards, causing the foot support pad 40 to move backwards accordingly, ensuring the heel accurately falls into the support area of ​​the U-shaped groove 41. For patients with shorter calves, the support frame 20 can be pushed inwards, bringing the foot support pad 40 closer to the body, achieving the same precise positioning effect. This adjustment mechanism, combined with the anti-slip design of the supporting foot 30, ensures the stability of the device in various body positions, keeping the ankle joint in the ideal 90° functional position and effectively counteracting gravity-induced foot drop.

[0015] The base plate 10 serves as a rigid base, providing even support for the upper flexible footrest pad 40 and preventing concentrated local pressure. The flexible edging 50 around the base plate 10 eliminates potential damage to the patient's skin and bedding from hard edges, enhancing safety. The outermost protective cover 60 is made of breathable, moisture-wicking, and washable fabric, enhancing foot comfort and facilitating daily cleaning and maintenance, meeting the hygiene needs of long-term bedridden patients.

[0016] The support foot 30 and the adjustable support frame 20 together form a stable chassis system; the base plate 10 and the flexible edging 50 form a safe load-bearing platform; the foot pad 40 and its U-shaped groove 41 are the core functional components, combined with the hygienic protection function of the protective sleeve 60. The components work together to maintain the functional position of the ankle joint while relieving pressure and managing body position, thus achieving the dual effect of preventing foot drop and heel pressure sores.

[0017] II. Implementation Method: A novel adjustable support footrest sponge pad includes a base plate 10. The base plate 10 is made of rectangular medium-density fiberboard, with a thickness of approximately 1 cm, a length of approximately 40 cm, and a width of approximately 30 cm. The base plate 10 is surrounded by a flexible edging 50, which is composed of high-elastic sponge covered with artificial leather.

[0018] A support frame 20 is provided at the center of the long side of the lower surface of the base plate 10. In this embodiment, the support frame 20 is a metal telescopic tube structure with a series of equally spaced positioning holes on the tube wall, and a spring locking pin mechanism is installed on the matching fixing seat. The support frame 20 can be adjusted back and forth by pressing the locking pin, with an adjustment stroke of about 15 cm. Releasing the locking pin will automatically lock the position. A support foot 30 is connected to the end of the support frame 20. In this embodiment, the support foot 30 is a rubber anti-slip pad, which is fixed to the bottom of the bracket by screws to enhance the anti-slip stability of the device on the bed surface.

[0019] A foot support pad 40 is glued to the upper surface of the base plate 10 with medical adhesive. The pad 40 is made of slow rebound memory foam. Two symmetrically distributed U-shaped grooves 41 are molded on the upper surface of the foot support pad 40 to support the patient's heel.

[0020] The entire set of components is covered by a protective cover 60, which is made of elastic cotton fabric and can be easily removed and washed.

[0021] In use, place the device under the patient's feet. Adjust the front and back position of the support frame 20 so that the patient's heels are accurately inserted into the U-shaped groove 41. After locking the support frame 20, it can be used stably. Regularly remove the protective cover 60 for cleaning to maintain hygiene.
