Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leg support technology, specifically referring to a leg support for nursing care. Background Technology
[0002] In the field of medical care, leg elevation is a common nursing technique aimed at promoting blood circulation in the lower limbs, reducing edema, and alleviating symptoms of certain diseases.
[0003] Early elevation pads mostly used fixed angles and shapes. For patients with varying degrees of swelling due to leg trauma, fixed-angle elevation pads could not adjust the elevation angle according to the degree of swelling to achieve the best blood return effect. This not only affected the nursing effect, but may also aggravate the patient's discomfort due to unreasonable elevation angles.
[0004] Some attempts have been made to include leg-raising mats with adjustable elevation angles, which have improved the situation to some extent. However, these mats can only change the overall leg elevation angle, neglecting the importance of adjusting the angle between the thigh and calf. The optimal bending angle between the thigh and calf varies depending on the patient's physiological state and condition. Existing leg-raising mats cannot meet this need, forcing patients to maintain a single, potentially uncomfortable leg posture for extended periods during care, thus failing to fully meet the diverse care needs of patients. Utility Model Content
[0005] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a leg support for nursing care, which effectively solves the problem that existing leg braces cannot meet the needs of use.
[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows: A leg support for nursing includes a support base and a thigh support plate. The thigh support plate is hinged to one end of the support base via a rotating shaft. The base has mounting grooves on both sides. A threaded rod is horizontally rotatably mounted in the mounting groove. A rotating block is fixed to one end of the threaded rod. A moving block that moves horizontally relative to the mounting groove is threadedly connected to the threaded rod. A connecting plate is fixed to the outer side of the thigh support plate along its axial direction. A calf support plate is hinged to one end of the connecting plate. A limit structure is provided between the ends of the calf support plate and the connecting plate. A connecting rod is hinged to the connecting plate. One end of the connecting rod is hinged to the moving block.
[0007] Preferably, the limiting structure includes an annular rack, which is located at the end of the connecting plate. A limiting groove is embedded on the outer side of the lower leg support plate. A limiting rod is fixed in the limiting groove. A movable plate is slidably mounted on the limiting rod. The outer side of the movable plate is in close contact with the inner wall of the limiting groove. A fan-shaped toothed plate that meshes with the annular rack is fixed on the movable plate. A spring is fitted over the limiting rod and fixed to the inner wall of the limiting groove and the outer side of the movable plate.
[0008] Preferably, one end of the movable plate extends to the outer side of the fan-shaped toothed plate, making it easy to push and convenient to use.
[0009] Preferably, a support guide plate is fixed to one end of the support base near the thigh support plate, and the upper surface of the support guide plate is inclined and maintains a smooth transition with the thigh support plate.
[0010] Preferably, both the calf support plate and the thigh support plate have Velcro fastening straps on one side and buckles on the other side.
[0011] Preferably, the middle part of both the calf support plate and the thigh support plate is concave to form an arc-shaped receiving space.
[0012] The beneficial effects achieved by adopting the above-described structure are as follows:
[0013] 1. By rotating the thigh support plate, the overall leg elevation angle can be easily adjusted. Nursing staff can adjust the elevation angle to the most suitable position at any time based on changes in the patient's condition and feedback on physical comfort, which greatly improves the pertinence and effectiveness of nursing care.
[0014] 2. A connecting plate is installed between the calf support plate and the thigh support plate, and the calf support plate rotates relative to the connecting plate. The angle is fixed by a limiting structure, which can adaptively adjust the angle between the thigh and the calf to meet the diverse nursing needs of patients. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.
[0022] like Figure 1-4 As shown, the present invention proposes a leg support for nursing care, including a support base 1 and a thigh support plate 2. The thigh support plate 2 is hinged to one end of the support base 1 via a pivot. The base has mounting grooves 3 on both sides. A threaded rod 4 is horizontally rotatable in the mounting groove 3. A rotating block 5 is fixed to one end of the threaded rod 4. A moving block 6 that moves horizontally relative to the mounting groove 3 is threadedly connected to the threaded rod 4. A connecting plate 7 is fixed to the outer side of the thigh support plate 2 along its axial direction. A lower leg support plate 8 is hinged to one end of the connecting plate 7. A limit structure 9 is provided between the ends of the lower leg support plate 8 and the connecting plate 7 to fix the angle of the lower leg support plate 8. A connecting rod 10 is hinged to the connecting plate 7. One end of the connecting rod 10 is hinged to the moving block 6. When the moving block 6 is pushed to move on the mounting groove 3, the moving block 6 drives the connecting rod 10 to rotate, thereby causing the thigh support plate 2 to rotate around the connection point with the support base 1, thereby adjusting the overall leg elevation angle.
[0023] like Figure 4As shown, the limiting structure 9 includes an annular rack 11, which is located at the end of the connecting plate 7. A limiting groove 12 is embedded on the outer surface of the lower leg support plate 8. A limiting rod 13 is fixed in the limiting groove 12. A movable plate 14 is slidably mounted on the limiting rod 13. The outer side of the movable plate 14 is in close contact with the inner wall of the limiting groove 12. A fan-shaped toothed plate 15 that meshes with the annular rack 11 is fixed on the movable plate 14. A spring is sleeved on the limiting rod 13 and fixed to the inner wall of the limiting groove 12 and the outer surface of the movable plate 14. Spring 16, one end of the movable plate 14 extends to the outer side of the fan-shaped toothed plate 15 for easy pushing and convenient use. Pushing the movable plate 14 away from the annular rack 11 causes the fan-shaped toothed plate 15 to move, disengaging it from the annular rack 11. After pushing the lower leg support plate 8 to the required angle, the movable plate 14 is released. Under the action of the spring 16's own restoring force, the movable plate 14 is pushed to drive the fan-shaped toothed plate 15 to engage with the annular rack 11, thereby fixing the angle of the lower leg support plate 8.
[0024] like Figure 1 , 3 As shown, a support guide plate 17 is fixed to one end of the support base 1 near the thigh support plate 2. The upper surface of the support guide plate 17 is inclined and smoothly transitions with the thigh support plate 2. The root of the thigh can be naturally placed on the support guide plate 17. With the help of the inclined angle and stable support of the support guide plate 17, the support and comfort of the thigh area are improved.
[0025] like Figure 1 , 2 As shown, the middle part of the calf support plate 8 and the thigh support plate 2 is concave to form an arc-shaped receiving space. One side of the calf support plate 8 and the thigh support plate 2 is fixed with a Velcro fastening strap 19, and the other side is fixed with a buckle 18. The Velcro fastening strap 19 is passed through the buckle 18 to fix the calf and thigh parts respectively.
[0026] In practical use, the nursing staff first rotates the rotating block 5 to drive the threaded rod 4 to rotate, which in turn drives the moving block 6 to move. The moving block 6 then drives the connecting rod 10 to rotate, which in turn drives the connecting plate 7 and the thigh support plate 2 to rotate, thus adjusting the overall leg elevation angle. Next, based on the specific condition of the patient's leg, the moving plate 14 is pushed to the end away from the annular rack 11 to move the fan-shaped toothed plate 15, disengaging it from the annular rack 11. After pushing the lower leg support plate 8 to the required angle, the moving plate 14 is released. Under the action of the spring 16's own restoring force, the moving plate 14 is pushed to drive the fan-shaped toothed plate 15 to engage with the annular rack 11, thereby fixing the angle of the lower leg support plate 8. The patient places their leg on the support, with the thigh root on the support guide plate 17 and the lower leg on the lower leg support plate 8. The lower leg and thigh can be fixed separately by passing the Velcro strap 19 through the buckle 18.
[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
