Description

Technical Field

[0001] This utility model belongs to the field of turning over assistance technology, specifically relating to a tilt-adjustable turning over assistance device. Background Technology

[0002] Pressure ulcers are injuries to the skin and / or tissues confined to a positional area. Common causes include ischemia, hypoxia, and nutrient deficiency resulting from prolonged vertical pressure, leading to skin tissue deformation and necrosis. They frequently occur in patients who do not change position for extended periods. Over 10% of people who are bedridden or in wheelchairs develop pressure ulcers, and elderly individuals with pressure ulcers have a four times higher mortality rate than those without. Pressure ulcer treatment is difficult, requires a long nursing period, and has a high recurrence rate in bedridden patients. Current methods for preventing pressure ulcers include elevating pressure-prone areas (tailbone, lumbar region) and frequent turning. However, the weight of the human body makes bedside care difficult, and bedridden patients often lack the strength to cooperate, making turning difficult. Conventional turning aids have a large inclination angle, making them difficult to insert under the patient; therefore, there is a need to design a more user-friendly turning aid that can elevate the affected area at a specific angle. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary device that reduces the difficulty of turning over for bedridden patients and elevates the affected area to prevent pressure sores.

[0004] This utility model provides a tilt-adjustable turning assist device, including a bottom support plate and a top support plate; its characteristic is that it further includes a support adjustment mechanism disposed between the bottom support plate and the top support plate. One side edge of the bottom support plate and the top support plate is rotatably connected. The support adjustment mechanism provides support to the top support plate and adjusts its own height, changing the included angle between the bottom support plate and the top support plate.

[0005] Preferably, the support adjustment mechanism includes two support blocks, two adjusting blocks, a support rod assembly, and an adjusting screw. The two support blocks are fixed to opposite sides of the bottom and top support plates, respectively. The support rod assembly includes four support rods rotatably connected in a quadrilateral shape. The rotation center between every two connected support rods is connected to the two support blocks and the two adjusting blocks, respectively.

[0022] The present invention will be further described below.

[0023] like Figure 1 As shown, an inclined adjustable turning assist device includes a bottom support plate 1, a top support plate 2, a connecting structure 3, and a support adjustment mechanism 4. One edge of the bottom support plate 1 and the top support plate 2 is referred to as the insertion side, and the opposite edge is referred to as the support side.

[0024] The insertion side of the bottom support plate 1 and the insertion side of the top support plate 2 are rotatably connected by a connecting structure 3. The connecting structure 3 comprises a flexible sheet material that can be bent arbitrarily; in this embodiment, a textile fabric is preferred. In this embodiment, the connection method between the connecting structure 3 and the bottom support plate 1 and the top support plate 2 is as follows: a connecting gap is provided on the insertion side of the bottom support plate 1 and the top support plate 2. The connecting structure 3 has a ring-shaped structure and passes around and through the connecting gap on the bottom support plate 1 and the top support plate 2, so that the bottom support plate 1 and the top support plate 2 are connected together and can rotate relative to each other.

[0025] The top support plate 2 has a central hole; the outer edges of the top support plate 2, the edge of the central hole, and the outer edges of the bottom support plate 1 are all covered with cushioning strips. The cushioning strips are made of elastic material, preferably rubber and sponge in this embodiment. The cushioning strips help protect the user from impact injuries. The central hole on the top support plate 2 is used to avoid the user's affected area, thereby preventing squeezing injuries to the user's affected area during assisted turning.

[0026] like Figure 2 As shown, the support adjustment mechanism 4 is disposed between the support sides of the bottom support plate 1 and the top support plate 2. The support adjustment mechanism 4 includes two support blocks 4-1, two adjustment blocks 4-2, two support rod assemblies, an adjustment screw 4-3, and an adjustment handle 4-4. The two support blocks 4-1 are respectively fixed to the opposite sides of the bottom support plate 1 and the top support plate 2. Both the two support blocks 4-1 and the two adjustment blocks 4-2 are located between two mutually aligned support rod assemblies.

[0027] The support rod assembly includes a first support rod 4-5, a second support rod 4-6, a third support rod 4-7, and a fourth support rod 4-8, which are rotatably connected end-to-end to form a quadrilateral. The hinge shaft between the first support rod 4-5 and the second support rod 4-6 is fixedly or rotatably connected to a support block 4-1 on the bottom support plate 1. The hinge shaft between the third support rod 4-7 and the fourth support rod 4-8 is fixedly or rotatably connected to a support block 4-1 on the top support plate 2. The hinge shaft between the second support rod 4-6 and the third support rod 4-7 is fixedly or rotatably connected to one of the adjusting blocks 4-2. The hinge shaft between the fourth support rod 4-8 and the first support rod 4-5 is fixedly or rotatably connected to the other adjusting block 4-2.

[0028] In this embodiment, the first support rod 4-5, the second support rod 4-6, the third support rod 4-7, and the fourth support rod 4-8 are of the same length. The adjusting screw 4-3 and the through hole on one of the adjusting blocks 4-2 form a rotating pair. The adjusting screw 4-3 and the threaded hole on one of the adjusting blocks 4-2 form a helical pair.

[0029] An adjusting handle 4-4 is fixed to the end of the adjusting screw 4-3 away from the connecting structure 3; by manually rotating the adjusting handle 4-4, the distance between the two support blocks 4-1 can be easily adjusted, thereby changing the relative angle between the bottom support plate 1 and the top support plate 2.

[0030] When the bottom support plate 1 and the top support plate 2 are adjusted to their minimum angle, the overall thickness is small, making it easy to insert between the user's back and the bed surface. When the bottom support plate 1 and the top support plate 2 are adjusted to their maximum angle, they can push the user into a tilted position, thereby assisting the user in turning over.

[0031] In some other embodiments, a wedge-shaped guide block is connected to the insertion side of the bottom support plate 1. The wedge-shaped guide block is made of an elastic material such as sponge; the thickness of the wedge-shaped guide block gradually decreases in the direction away from the bottom support plate 1. The wedge-shaped guide block helps to further reduce the thickness of the entire turning aid device on the insertion side, thereby facilitating the insertion of the turning aid device between the user's back and the bed surface.

[0032] like Figure 3 As shown, the working principle of this utility model is as follows:

[0033] First, rotate the adjustment handle 4-4 in the first direction to minimize the relative angle between the bottom support plate 1 and the top support plate 2; then insert the insertion sides of the bottom support plate 1 and the top support plate 2 between the bed surface and the user's waist or back.

[0034] Next, rotate the adjustment handle 4-4 in the second direction to gradually open the support rod assembly, push the top support plate 2 to flip upward, and push the user to perform a turning motion.
