The lateral positioning device for preventing pressure injuries described in this invention, through its bed frame, allows for free adjustment of the bed's tilt angle according to different nursing lateral positioning needs, thereby improving the prevention and treatment of pressure injuries. By setting up a lateral positioning nursing bed that can tilt left and right, it not only adaptively adjusts the bed's tilt angle according to the patient's required lateral positioning angle, but also meets the needs of patients getting out of bed frequently for care and changing bedding, greatly reducing the workload of nursing staff. The ingenious design of this device is reflected in its flexible rotating connection mechanism, which allows the bed frame to achieve stable and precise angle adjustment with the assistance of two supporting arm rotating columns.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown in the embodiment of the present invention, a lateral positioning device for preventing pressure injuries includes a main support 1; multiple support legs 11 are fixedly connected to the bottom end of the main support 1; wheel disks 12 are fixedly connected to both ends of the main support 1; a rotating column 13 is rotatably connected to the inner wall of the center of the wheel disk 12; a bed frame 14 is fixedly connected to the outer wall of the rotating column 13, and the bed frame 14 is located between two rotating columns 13; when providing long-term bed rest for patients who have lost their mobility to prevent pressure injuries, the main support 1, in conjunction with the multiple support legs 11, serves as the main support for the bed frame 14. For support, the bed frame 14 is rotatably connected to two wheel disks 12 via rotating columns 13 at both ends. A bed board is then attached to the bed frame 14 to form a nursing bed. When the patient is bedridden for extended periods, the bed frame 14 is balanced and its angle fixed to ensure parallelism on both sides, accommodating the patient's prolonged lying position. When the patient requires slight side-lying care, the caregiver holds the bed frame 14 and rotates it slightly to one side using the rotating columns 13. After rotation, the tilt angle of the bed frame 14 is fixed, redistributing the patient's weight and reducing pressure on previously compressed areas. This reduces pressure by transferring it to other areas, effectively shifting the burden. Caregivers can then assist the patient in turning to their side from the higher side of the bed frame 14. With the bed frame 14 tilted to the left, the patient's upper body and pelvis will naturally tilt slightly to the left under gravity. Caregivers only need to gently push the shoulder or hip to allow the patient to turn to their side, significantly reducing physical exertion and converting the patient's body from a supine to a side-lying position. This is particularly suitable for heavier patients, facilitating their need to turn to their side. When the patient needs to get out of bed for care or to change positions... When changing bedding, rotate the bed frame 14 to one side significantly with the rotating column 13. Note that the patient's body must be secured to the bed board before rotation. After rotation, fix the tilt angle of the bed frame 14. The caregiver can then help the patient get out of bed and change bedding from the lower side of the bed frame 14. After care and bedding changes are completed, the patient can be returned to the nursing bed from the lower side of the bed frame 14. This facilitates the patient's need to get out of bed and allows for free adjustment of the tilt angle of the nursing bed according to different care needs, thereby improving the prevention and treatment of pressure injuries. By setting up a side-lying nursing bed that can tilt left and right, the tilt angle of the bed can be adjusted adaptively according to the patient's required side-lying angle. It can also meet the needs of patients to get out of bed for care and change bedding from time to time, greatly reducing the workload of nursing staff. The ingenious design of this device is reflected in its flexible rotating connection mechanism, which allows the bed frame 14 to achieve smooth and precise angle adjustment with the assistance of the two support arm rotating columns 13. In addition, the device has a simple structure, is easy to assemble and maintain, and reduces the cost of use. At the same time, the key components are made of high-strength materials, which ensures the stability and durability of the device, allowing it to maintain a good working condition during long-term use. By periodically adjusting the tilt angle, the contact point between the body and the bed surface can be changed, reducing the risk of pressure sores caused by prolonged pressure on the same area. By manually tilting left and right alternately, the effect of manual turning can be simulated in a short time, avoiding continuous pressure on the same area for more than two hours. It should be noted that simulated turning cannot replace manual turning.

[0024] A ring plate 2 is fixedly connected to the wheel 12; a sliding block 21 is slidably connected to the inner wall of the ring plate 2, and one end of the sliding block 21 is fixedly connected to the outer wall of the bed frame 14; multiple angle holes are opened on the wheel 12; a No. 1 bolt 22 is threadedly connected to both the sliding block 21 and the wheel 12, and the No. 1 bolt 22 is threaded into the angle hole; when the side-lying care bed is tilted, the caregiver holds the bed frame 14 and rotates it on the wheel 12 in conjunction with the rotating column 13, and the sliding block 21 slides synchronously on the inner wall of the ring plate 2 along with the bed frame 14. After the tilt angle of the side-lying care bed is adjusted, the No. 1 bolt 22 is threaded into the angle hole of the sliding block 21 and the wheel 12 to realize the angle adjustment of the side-lying care bed, thereby facilitating the adjustment of the side-lying care bed. This device addresses the needs of patients requiring lateral repositioning care, bed ambulation, and bedding changes. By incorporating a ring plate 2, sliding block 21, and bolt 22, the angle of the lateral repositioning bed can be fixed, ensuring the bed frame 14 remains stable when tilted and preventing swaying during care, thus improving safety. The sliding block 21 slides on the inner wall of the ring plate 2, and the bolt 22 is threaded into the angle holes of the sliding block 21 and the wheel 12, fixing the tilt angle of the lateral repositioning bed. This simple and quick operation improves care efficiency. Furthermore, the multiple angle holes allow for fixing the lateral repositioning bed at different tilt angles, meeting the care needs of different patients and further enhancing the practicality and flexibility of the device.

[0025] like Figures 1 to 5As shown, the bed frame 14 is hinged with multiple support plates 31, 32, and 33. Support plate 31 is located at the center of the bed frame 14. One side of support plate 32 is attached to support plate 31, and the other side of support plate 32 is attached to support plate 33. During the use of the side-care bed, the multiple support plates 31, 32, and 33 hinged to the bed frame 14 are combined to form a bed board. Two opposing support plates 31 are located at the center, two opposing support plates 32 are attached to one side of the two support plates 31, and two opposing support plates 33 are attached to one side of the two support plates 32. The width of support plate 31 is greater than the width of support plates 32 and 33. The bed board is segmented, and when adjusting the segmented bed board, a manual lift can be used individually according to different side-care needs. The adjustable support plates 31, 32, and 33, along with lifting devices such as jacks, allow for adjustment of the side-lying angle of different areas of the bed, making it more comfortable for patients when lying on their side. The segmented bed design also facilitates localized care by nursing staff, improving the precision and flexibility of care. Furthermore, the relatively hinged support plates 31, 32, and 33 allow the bed to flexibly adapt to different tilt angles of the side-lying care bed, ensuring stability and fit between the bed and the bed, further enhancing safety and comfort. All support plates 31, 32, and 33 are made of high-strength and lightweight materials, ensuring load-bearing capacity while facilitating handling and assembly by nursing staff, reducing physical exertion during care and improving efficiency.

[0026] Multiple electric push rods 4 are fixedly connected to the inner wall of the bed frame 14, and the multiple electric push rods 4 are arranged in pairs opposite each other; the output end of each electric push rod 4 is fixedly connected to a rotating shaft 41, and the multiple rotating shafts 41 are respectively rotatably connected to the bottom ends of the first support plate 31, the second support plate 32, and the third support plate 33; when adjusting the angle of the segmented bed board, the multiple electric push rods 4 are fixed on the bed frame 14, and the rotating shafts 41 connected to the electric push rods 4 are supported at the bottom of the multiple segmented bed boards. According to the side-lying needs of different parts of the patient's body, the electric push rods 4 can be freely controlled in conjunction with the rotating shafts 41 to lift or lower the supported bed board, thereby realizing the angle adjustment of different areas of the segmented bed board, so that the patient can better fit the curve of their body when lying on their side, improving the side-lying comfort. The design enhances comfort and care effectiveness. Multiple electric push rods 4 are positioned in pairs on the inner wall of the bed frame 14, and multiple rotating shafts 41 are connected to the bottom ends of the first support plate 31, the second support plate 32, and the third support plate 33. This design ensures the stability and balance of the bed board during adjustment, preventing tilting and wobbling due to uneven force, thus further improving the safety of care. Furthermore, the electric push rods 4 and rotating shafts 41 are made of high-precision and durable materials, ensuring stability and reliability during long-term use and reducing maintenance costs. Additionally, the electric lifting structure at the electric push rods 4 can be replaced with a manual lifting structure according to cost requirements, making the segmented bed board highly adaptable to assembly.

[0027] like Figure 1 , Figure 2 and Figure 5 As shown, a first anti-slip pad 5 is fixedly attached to the first support plate 31; a second anti-slip pad 51 is fixedly attached to the second support plate 32; and a third anti-slip pad 52 is fixedly attached to the third support plate 33. When the bedding is placed on the segmented bed board, the first anti-slip pad 5, the second anti-slip pad 51, and the third anti-slip pad 52 are respectively fixed to multiple segmented bed boards. This increases the friction on the bedding after the bed board is tilted, preventing it from slipping and falling off, reducing the chance of the bedding slipping off due to the tilt of the bed board, and ensuring the patient's comfort during side-lying care and getting out of bed. In addition, the design of the first anti-slip pad 5, the second anti-slip pad 51, and the third anti-slip pad 52 makes them easy to disassemble and clean, facilitating regular cleaning and maintenance by nursing staff, maintaining the hygiene of the bed board, and further improving the quality of care.

[0028] like Figures 1 to 4As shown, both sides of the support leg 11 are slidably connected to top rods 6, and the top end of the top rod 6 is set as a semi-circle; the outer wall of the top rod 6 is sleeved with an elastic element 61; when the bed frame 14 is balanced, the elastic elements 61 on both sides of the support leg 11 elastically support the top rod 6, so that the semi-circular top end of the top rod 6 rests on the bottom edge of the bed frame 14. The support of multiple top rods 6 and elastic elements 61 can improve the stability of the bed frame 14 assembly. When the bed frame 14 is tilted, the auxiliary support of multiple top rods 6 and elastic elements 61 can keep the bed frame 14 stable during the tilting process, reduce the amplitude of swaying, and improve the safety of the side-lying nursing bed during the adjustment process; the semi-circular top end design of the top rod 6 can better fit the bottom edge of the bed frame 14, adapt to the compression when the bed frame 14 is tilted, and further improve the stability of the support.

[0029] Side guards 7 are provided on both sides of the bed frame 14; multiple No. 2 bolts 71 are threaded onto the bed frame 14, and the No. 2 bolts 71 penetrate the side guards 7; when the patient is placed on the side-lying care bed, the two side guards 7 are respectively fixed to the two sides of the bed frame 14 by multiple No. 2 bolts 71. The two side guards 7 protect the two sides of the bed frame 14, reducing the possibility of the patient falling out of the bed due to body swaying during side-lying and getting out of bed, thus improving the safety of nursing care. The side guards 7 are designed to be detachable, which makes it easy for nursing staff to quickly assemble or disassemble the side-lying care bed as needed.

[0030] Inflatable pads 8 are fixed to the upper surfaces of both sides of the bed frame 14. The inflatable pads 8 are attached to the outer wall of the side guards 7. When the two side guards 7 cover the two sides of the bed frame 14, the two inflatable pads 8 are fixed to the side of the two side guards 7 near the bed board. After the two inflatable pads 8 are inflated, they can protect the patient and reduce the squeezing force formed by the patient contacting the inflatable pads 8 when the bed frame 14 is tilted. At the same time, after the side guards 7 are removed, the inflatable pads 8 are deflated to be level with the bed board. The inflatable pads 8 can reduce the edge friction when the patient gets out of bed and improve the comfort of the side-lying nursing bed during use.

[0031] Multiple rotating rods 9 are rotatably connected to both ends of the bed frame 14; a connecting plate 91 is fixedly connected to the rotating rod 9; when the patient is receiving side-lying care, the connecting plate 91 facing one side is rotated and lowered in conjunction with the rotating rod 9. The rotating rod 9 has an angle self-locking function. After the connecting plate 91 is rotated to be parallel to the bed board with the angle not adjusted, the patient's arms and legs can be supported by the two connecting plates 91 at the head and foot of the bed, which enhances the patient's comfort experience when receiving side-lying care and reduces the stress on the same part of the patient when turning to the side.

[0032] The connecting plate 91 has multiple threaded holes; a threaded rod 92 is threadedly connected to the threaded holes of the connecting plate 91; when the connecting plate 91 is horizontal on the bed, the threaded rod 92 can be adjusted by rotating it in the threaded hole, supporting the end of the connecting plate 91 away from the rotating rod 9 on the bed, ensuring stability when the patient's arms and legs are supported. When the connecting plate 91 is vertical on the bed, multiple medical devices can be threadedly connected to the threaded holes, such as installing an IV drip holder on the rotating rod 9, using the rotating rod 9 as a support frame for IV drips, enhancing the practicality of the side-lying care bed, making the device not only suitable for side-lying care of patients, but also able to meet other medical needs, further improving the utilization rate of the device.

[0033] Working Process: When providing long-term bed rest to prevent pressure injuries in patients who have lost mobility, the main support 1, along with multiple support legs 11, serves as the primary support for the bed frame 14. The bed frame 14 is rotatably connected to two wheel disks 12 via rotating columns 13 at both ends. A bed board is then attached to the bed frame 14 to form a nursing bed. When the patient is bedridden for extended periods, the bed frame 14 is balanced and its angle fixed to ensure parallelism on both sides, accommodating the patient's prolonged lying position. When the patient requires slight side-lying care, the caregiver holds the bed frame 14 and, with the help of the rotating columns 13, slightly rotates it to one side. After rotation, the tilt angle of the bed frame 14 is fixed. This redistributes the patient's weight, reducing pressure on previously compressed areas and transferring pressure to other parts of the body, thus achieving pressure relief. The effect of the tilting mechanism allows caregivers to assist the patient in turning to their side from the higher side of the bed frame 14. With the bed frame 14 tilted to the left, the patient's upper body and pelvis will naturally tilt slightly to the left under gravity. Caregivers only need to gently push the patient's shoulders or hips to allow them to turn to their side, significantly reducing physical exertion and converting the patient's body from a supine to a side-lying position. This is particularly suitable for heavier patients, facilitating their need to turn to their side. When the patient needs to get out of bed for care or to change bedding, the bed frame 14, along with the rotating column 13, can be rotated significantly to one side. It is important to note that the patient's body must be secured to the bed board before rotation. After rotation, the tilt angle of the bed frame 14 should be fixed, and caregivers can then assist the patient in getting out of bed for care or to change bedding from the lower side of the bed frame 14. After nursing care and changes are completed, the patient can be returned to the nursing bed from the lower side of the bed frame 14, facilitating the patient's ability to get out of bed. The bed's tilt angle can be freely adjusted according to different nursing needs, thereby improving the prevention and treatment of pressure injuries. Manual left and right tilting can simulate the effect of manual turning over for a short time, avoiding continuous pressure on the same area for more than two hours. It should be noted that simulated turning over cannot replace manual turning. When adjusting the side-lying nursing bed, the caregiver holds the bed frame 14 and rotates it on the wheel 12 with the rotating column 13. The sliding block 21 slides synchronously on the inner wall of the ring plate 2 along with the bed frame 14. After adjusting the side-lying nursing bed's tilt angle, the first bolt 22 is threaded into the angle hole of the sliding block 21 and the wheel 12 to achieve the desired side-lying position. The adjustable angle of the bed facilitates side-lying care, as well as care for patients getting out of bed and changing bedding. The ring plate 2, sliding block 21, and bolt 22 allow for angle fixation of the side-lying care bed, ensuring stability of the bed frame 14 when tilted and preventing swaying during care, thus improving safety. The sliding block 21 slides on the inner wall of the ring plate 2, and the bolt 22 is threaded into the angle holes of the sliding block 21 and the wheel 12, fixing the tilt angle of the side-lying care bed. This simple and quick operation improves care efficiency. Furthermore, the multiple angle holes allow for fixing the side-lying care bed at different tilt angles, meeting the care needs of different patients and further enhancing the practicality and flexibility of the device. When the side-care bed is in use, the bed board is composed of multiple support plates 31, 32, and 33 hinged to the bed frame 14. Two opposing support plates 31 are located in the center, two opposing support plates 32 are close to one side of the two support plates 31, and two opposing support plates 33 are close to one side of the two support plates 32. The width of the support plate 31 is greater than the width of the support plates 32 and 33. The bed board is segmented. When adjusting the segmented bed board, different areas can be adjusted individually using manual lifters and jacks according to different side-care needs. The angles of support plates 31, 32, and 33 allow for adjustment of the side-lying angle in specific areas of the bed, making it more comfortable for the patient when lying on their side. The segmented bed design also facilitates localized care by nursing staff, improving the precision and flexibility of care. Furthermore, the relatively hinged joints of support plates 31, 32, and 33 allow the bed to flexibly adapt to different tilt angles of the side-lying care bed, ensuring stability and fit between the bed and the bed, further enhancing safety and comfort. When adjusting the angle of the segmented bed, multiple electric push rods 4 are fixed to the bed. On frame 14, the rotating shaft 41 connected to the electric push rod 4 is supported at the bottom of multiple segmented bed boards. According to the patient's side-lying needs for different parts of their body, the electric push rod 4, in conjunction with the rotating shaft 41, can freely control the electric push rod 4 to lift or lower the supported bed board, achieving angle adjustment for different areas of the segmented bed board. This allows the patient to better conform to their body curves when lying on their side, improving comfort and nursing effectiveness. With multiple electric push rods 4 arranged in pairs on the inner wall of bed frame 14, and multiple rotating shafts 41 connected to the bottom of support plate 31, support plate 32, and support plate 33, this design ensures the stability and balance of the bed board during adjustment, preventing the bed board from shifting. The uneven force distribution causes tilting and swaying, further enhancing the safety of nursing care. When bedding is placed on the segmented bed board, anti-slip mats 51, 51, and 52 are used to fix the bedding to multiple segments, increasing friction after the bed board tilts, preventing slippage and detachment, and reducing the likelihood of bedding slipping off due to the tilt. This ensures patient comfort during side-lying care and when getting out of bed. In addition, the design of anti-slip mats 51, 51, and 52 makes them easy to disassemble and wash, facilitating regular cleaning and maintenance by nursing staff, keeping the bed board hygienic, and further improving the quality of nursing care. When the bed frame 14 is balanced, the elastic elements 61 on both sides of the support legs 11 elastically support the top rods 6, so that the semi-circular tops of the top rods 6 rest against the bottom edge of the bed frame 14. The support of multiple top rods 6 and elastic elements 61 can improve the stability of the bed frame 14 assembly. When the bed frame 14 is tilted, the auxiliary support of multiple top rods 6 and elastic elements 61 can keep the bed frame 14 stable during tilting, reduce the amplitude of swaying, and improve the safety of the side-lying nursing bed during adjustment. The semi-circular top design of the top rods 6 can better fit the bottom edge of the bed frame 14, adapt to the compression when the bed frame 14 is tilted, and further improve the stability of the support. When a patient is placed on the side-lying care bed, two side panels 7 are threadedly fixed to both sides of the bed frame 14 using multiple No. 2 bolts 71. The two side panels 7 provide protection to both sides of the bed frame 14, reducing the risk of the patient falling out of bed due to body swaying during side-lying and getting out of bed, thus improving the safety of care. The side panels 7 are designed to be detachable, allowing caregivers to quickly assemble or disassemble the side-lying care bed as needed. When the two side panels 7 are protecting both sides of the bed frame 14, two inflatable cushions 8 are fixed to the side of the two side panels 7 closest to the bed board. When the two inflatable cushions 8 are inflated, they can protect the patient and reduce the squeezing force formed by the patient contacting the inflatable cushions 8 when the bed frame 14 is tilted. At the same time, after the side panels 7 are removed, the inflatable cushions 8 are deflated to be level with the bed board. The inflatable cushions 8 can reduce edge friction when the patient gets out of bed, improving the comfort of using the side-lying care bed. When a patient is being cared for in a side-lying position, the connecting plate 91 facing one side is lowered in conjunction with the rotating rod 9. The rotating rod 9 has an angle self-locking function. After the connecting plate 91 is rotated to be parallel to the bed board without adjustment, the patient's arms and legs can be supported by the two connecting plates 91 at the head and foot of the bed, enhancing the patient's comfort during side-lying care and reducing the stress on the same part of the patient's body when lying on their side. When the connecting plate 91 is horizontal on the bed, the threaded rod 92 can be adjusted by rotating it in the threaded hole, supporting the end of the connecting plate 91 away from the rotating rod 9 on the bed, ensuring stability when the patient's arms and legs are supported. When the connecting plate 91 is vertical on the bed, multiple medical devices can be threaded into the threaded hole, such as installing an IV drip holder on the rotating rod 9, using the rotating rod 9 as a support frame for IV drips, enhancing the practicality of the side-lying care bed. This makes the device not only suitable for side-lying care of patients but also able to meet other medical needs, further improving the utilization rate of the device.
