Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically a wearable turning aid and posture maintenance device. Background Technology

[0002] Against the backdrop of an aging population and increasing demands for postoperative rehabilitation and disability care, the nursing care of long-term bedridden individuals (such as disabled elderly, patients after spinal surgery, and those with lower limb paralysis) is becoming increasingly prominent. These individuals, due to loss or limitation of independent movement, rely on caregivers to assist with turning over in order to prevent complications such as pressure sores, lung infections, and muscle atrophy caused by prolonged bed rest. Clinical data shows that if elderly bedridden patients are not effectively turned over every 4 hours, the incidence of pressure sores can reach over 32%, with grade III and above pressure sores requiring treatment periods of 4-8 weeks. This not only increases patient suffering but also significantly raises the cost of home care and the burden on healthcare providers.

[0003] Currently, there are three main types of methods for assisting bedridden individuals to turn over, but all of them have significant limitations:

[0004] Firstly, manual turning relies on nurses' manual operation, which is not only labor-intensive (one or two nurses are needed to turn the patient each time, with a total daily operation time of more than 2 hours), but also affected by the differences in nurses' physical strength and experience. It is difficult to accurately control the turning angle (the ideal side-lying angle is 30°-45°) and frequency. In some operations, dragging movements may also cause skin abrasions or joint damage to the patient. Especially in nighttime nursing scenarios, nurses are prone to prolonged turning intervals when they are fatigued, which further increases the risk of complications.

[0005] Secondly, traditional assistive devices such as turning pillows and wedge-shaped cushions can only maintain a specific posture through passive support and cannot actively drive the patient to complete the turning action; moreover, such devices have poor adaptability (it is difficult to adjust the support position according to the patient's body shape), and they are prone to displacement due to slight movements of the patient during use, resulting in support failure. At the same time, they also restrict the patient's limb movement space and affect comfort. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a wearable turning-over assistance and posture maintenance device, which solves the problems of heavy physical burden during manual turning-over and discomfort caused by traditional rigid mechanisms.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A wearable turning aid and posture maintenance device includes a mounting plate. A rotating plate is rotatably connected to one side of the upper surface of the mounting plate, and a fixed plate is fixedly connected to the other side of the upper surface of the mounting plate. A mounting frame is fixedly connected to the rear end of the upper surface of the mounting plate. A sliding groove is formed in the middle of the upper surface of the mounting frame. A slide frame is slidably connected to the inner wall of the sliding groove. A rotary motor is fixedly connected to the upper end of the slide frame. A flipping frame is fixedly connected to the output end of the rotary motor. A slider is fixedly connected to the outer wall of the rear end of the rotating plate. The slider is slidably connected to the inner wall of the flipping frame. A protective pad is fixedly connected to the upper end of the rotating plate and the fixed plate. The front end and rear end of the upper surface of the protective pad are respectively fixedly connected to an upper restraint strap and a lower restraint strap by a protective rope.

[0009] The mounting plate has a base frame at both the front and rear ends. A storage slot is opened in the middle of the upper surface of the base frame. A double-acting screw is rotatably connected to both sides of the inner wall of the storage slot. A threaded sleeve is threaded to both sides of the outer wall of the double-acting screw. A hinge rod is hinged to the upper end of the threaded sleeve. A protective shell is fixedly connected to one side of the outer wall of the base frame. A synchronous motor is fixedly connected to the inner wall of the protective shell. The output end of the synchronous motor passes through the base frame into the storage slot and is fixedly connected to one side of the outer wall of the double-acting screw.

[0010] Through the above technical solution, the rotating frame, slider and rotating plate driven by the rotary motor can be used to help the patient complete the turning action smoothly, avoiding the impact of traditional rigid turning mechanism and reducing the physical burden of nursing staff to turn the patient manually; the upper and lower restraint straps can be adjusted with Velcro, and the cuff design ensures wearing comfort and fixation stability, avoiding pressure and discomfort, and the pad further avoids pressure on the patient when turning.

[0011] Furthermore, a medical bed is provided at the lower end of the mounting plate, and casters are fixedly connected to the four corners of the lower surface of the medical bed;

[0012] With the above technical solution, the use of casters allows caregivers to move the medical bed and adjust its position without having to physically move it, greatly reducing physical exertion.

[0013] Furthermore, the front and rear ends of one side of the upper surface of the mounting plate are provided with abutment grooves, and one side of the outer wall of the rotating plate abuts against the abutment grooves;

[0014] Through the above technical solution, when the device is not in a flipping state, the groove can provide precise support and limit the rotation plate.

[0015] Furthermore, limit grooves are provided on both sides of the inner wall of the flipping frame, and limit blocks are fixedly connected to both sides of the upper end of the outer wall of the slider. The limit blocks are slidably connected to the inner wall of the limit groove.

[0016] The above technical solution, with its features of a limiting groove for the flipping frame, a slider with a limiting block, and adaptability to sliding, has the advantage of ensuring structural safety and motion accuracy during the flipping process: the cooperation between the limiting groove and the limiting block can strictly limit the sliding trajectory of the slider in the flipping frame, preventing the slider from detaching from the flipping frame due to force or vibration during flipping, and avoiding interruption or deviation of the flipping action due to structural detachment.

[0017] Furthermore, a PLC control panel is provided on one side of the outer wall of the rear end of the mounting plate, and the PLC control panel is electrically connected to the rotary motor and the synchronous motor respectively;

[0018] With the above technical solution, the operations of turning over and adjusting height can be completed through the PLC control panel. The PLC control system can precisely control the speed and running time of the motor. For example, it can control the rotary motor to slowly drive the turning over (to avoid dizziness) and the synchronous motor to precisely adjust the height of the mounting plate, ensuring the accuracy and safety of the operation and reducing the nursing risks caused by human operation errors.

[0019] Furthermore, the upper part of the inner wall and the upper part of the outer wall of the upper and lower binding straps are respectively provided with hook and loop fasteners and hook and loop fasteners, the hook and loop fasteners are attached to each other, and cuffs are connected through the two sides of the outer wall of the upper binding strap.

[0020] Through the above technical solutions, the Velcro's adhesive structure can flexibly adjust the tightness of the restraint strap to suit patients of different body types, avoiding excessive tightness that compresses the skin and affects blood circulation, or excessive looseness that leads to fixation failure. The cuff design of the upper restraint strap allows the patient's arm to extend naturally, avoiding the tightness and restriction of movement caused by the restraint strap wrapping around the arm. At the same time, the cuff can further fix the position of the restraint strap, preventing it from slipping upwards during use, thus ensuring both wearing comfort and enhanced fixation effect.

[0021] Furthermore, the upper ends of the hinge rods are respectively hinged to the front and rear sides of the lower surface of the mounting plate;

[0022] Through the above technical solution, the hinged connection method allows the hinge rod to rotate flexibly with the lifting and lowering of the mounting plate, adapting to the angle changes of the mounting plate during height adjustment, avoiding structural jamming or uneven force due to rigid connection; at the same time, the symmetrical design of the hinges on both sides can make the mounting plate bear force evenly during lifting and lowering, preventing excessive force on one side from causing the mounting plate to tilt or deform, ensuring the overall structural stability of the device and extending its service life.

[0023] Furthermore, both sides of the lower surface of the base frame are fixedly connected with casters;

[0024] With the above technical solution, nursing staff do not need to carry heavy base frames and mounting plates. They can simply push the base frame to transfer the device from one medical bed to another, greatly reducing physical exertion.

[0025] This invention provides a wearable rolling-over aid and posture maintenance device. It has the following beneficial effects:

[0026] 1. This invention provides a wearable turning assist and posture maintenance device. With the help of a rotary motor to drive the turning frame, slider and rotating plate, it can help the patient complete the turning action smoothly, avoiding the impact of traditional rigid turning mechanisms and reducing the physical burden of manual turning by caregivers. With the upper and lower restraint straps, the tightness can be adjusted by Velcro. The cuff design ensures wearing comfort and fixation stability, avoiding pressure and discomfort. The pad further avoids pressure on the patient during turning.

[0027] 2. This invention provides a wearable turning aid and posture maintenance device. A synchronous motor drives a bidirectional screw to move the threaded sleeve block in opposite directions, so that the hinge rod moves while pushing the mounting plate to adjust its height. The overall height of the device can be adjusted according to the height of different medical beds, thus improving the adaptability of the device. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] like Figures 1-6 , Figure 9 As shown, this embodiment of the invention provides a wearable turning assistance and posture maintenance device, including a mounting plate 2. A rotating plate 21 is rotatably connected to one side of the upper surface of the mounting plate 2, and a fixed plate 23 is fixedly connected to the other side of the upper surface of the mounting plate 2. A mounting frame 24 is fixedly connected to the rear end of the upper surface of the mounting plate 2. A sliding groove 25 is provided in the middle of the upper surface of the mounting frame 24. A slide frame 26 is slidably connected to the inner wall of the sliding groove 25. A rotary motor 27 is fixedly connected to the upper end of the slide frame 26. A flipping frame 28 is fixedly connected to the output end of the rotary motor 27. A slider 210 is fixedly connected to the outer wall of the rear end of the rotating plate 21. The slider 210 is slidably connected to the inner wall of the flipping frame 28. A protective pad 3 is fixedly connected to the upper end of the rotating plate 21 and the fixed plate 23. An upper restraint strap 32 and a lower restraint strap 33 are respectively fixedly connected to the front end and the rear end of the upper surface of the protective pad 3 by a protective rope 31.

[0042] With the help of the rotary motor 27 driving the turning frame 28, the slider 210 and the rotating plate 21 to work together, the patient can be turned over smoothly, avoiding the impact of traditional rigid turning mechanisms and reducing the physical burden on nurses when turning over manually. With the upper restraint strap 32 and the lower restraint strap 33, the tightness can be adjusted by Velcro. The cuff design 34 ensures wearing comfort and fixation stability, avoiding pressure and discomfort. The pad 3 further avoids pressure on the patient when turning over.

[0043] A medical bed 1 is provided at the lower end of the mounting plate 2, and casters 11 are fixedly connected to the four corners of the lower surface of the medical bed 1.

[0044] With the universal wheels 11, nurses can easily move the medical bed 1 closer to the bedside for convenient care, or move it to a sunny area to improve the patient's living environment, greatly reducing physical exertion.

[0045] The front and rear ends of one side of the upper surface of the mounting plate 2 are provided with abutment grooves 22, and one side of the outer wall of the rotating plate 21 abuts against the abutment grooves 22.

[0046] When the device is in a non-turning state, i.e., when the patient is lying flat, the groove 22 can provide precise support and limit the rotation plate 21.

[0047] Limiting grooves 29 are provided on both sides of the inner wall of the flipping frame 28, and limiting blocks 211 are fixedly connected to both sides of the upper end of the outer wall of the slider 210. The limiting blocks 211 are slidably connected to the inner wall of the limiting grooves 29 respectively.

[0048] The flipping frame 28 is equipped with a limiting groove, and the slider 210 has a limiting block 211 and is adapted to sliding. The advantage is that it ensures the structural safety and movement accuracy of the flipping process: the cooperation between the limiting groove 29 and the limiting block 211 can strictly limit the sliding trajectory of the slider 210 in the flipping frame 28, prevent the slider 210 from detaching from the flipping frame 28 due to the force or vibration during flipping, and avoid the interruption or deviation of the flipping action due to structural detachment.

[0049] A PLC control panel 212 is provided on one side of the outer wall of the rear end of the mounting plate 2. The PLC control panel 212 is electrically connected to the rotary motor 27 and the synchronous motor 45 respectively.

[0050] The operation of the turning rotary motor 27 and the height adjustment synchronous motor 45 can be completed through the PLC control panel 212. The PLC control system can precisely control the speed and running time of the motors. For example, the rotary motor can be controlled to drive the turning slowly to avoid dizziness, and the synchronous motor can be precisely adjusted to adjust the height of the mounting plate to ensure the accuracy and safety of the action and reduce the nursing risks caused by human operation errors.

[0051] The upper part of the inner wall and the upper part of the outer wall of the upper binding strap 32 and the lower binding strap 33 are respectively provided with hook and loop fasteners and hook and loop fasteners. The hook and loop fasteners are attached to each other. The cuffs 34 are connected through the two sides of the outer wall of the upper binding strap 32.

[0052] The Velcro fastening structure allows for flexible adjustment of the tightness of the restraint straps, making them suitable for patients of different body types, such as obese or thin patients. This avoids excessive tightness that compresses the skin and affects blood circulation, or excessive looseness that causes the restraint to fail and shift when the patient turns over. The cuff design of the upper restraint strap 32 allows the patient's arm to extend naturally, avoiding the tightness and restriction of movement caused by the restraint strap wrapping around the arm, such as when the patient raises their hand or grasps objects. At the same time, the cuff 34 can further secure the position of the restraint straps, preventing them from slipping upwards during use, thus ensuring both wearing comfort and enhanced fixation.

[0053] Example 2:

[0054] like Figures 7-8 As shown, this embodiment of the invention provides a wearable turning-over assistance and posture maintenance device. A base frame 4 is provided at both the front and rear ends of the upper surface of the mounting plate 2. A storage slot 41 is provided in the middle of the upper surface of the base frame 4. Bidirectional screws 42 are rotatably connected to both sides of the inner wall of the storage slot 41. Threaded sleeves 43 are threadedly connected to both sides of the outer wall of the bidirectional screws 42. A hinge rod 44 is hinged to the upper end of each threaded sleeve 43. A protective shell 46 is fixedly connected to one side of the outer wall of the base frame 4. A synchronous motor 45 is fixedly connected to the inner wall of the protective shell 46. The output end of the synchronous motor 45 passes through the base frame 4 to the interior of the storage slot 41 and is fixedly connected to one side of the outer wall of the bidirectional screw 42.

[0055] The synchronous motor 45 drives the bidirectional screw 42 to move the threaded sleeve 43 in opposite directions, so that the hinge rod 44 moves and pushes the mounting plate 2 to adjust its height. This allows the overall height of the device to be adjusted according to the height of different medical beds 1, thus improving the adaptability of the device.

[0056] The upper ends of the hinge rods 44 are respectively hinged to the front and rear sides of the lower surface of the mounting plate 2.

[0057] The hinged connection allows the hinge rod 44 to rotate flexibly with the lifting and lowering of the mounting plate 2, adapting to the angle changes of the mounting plate 2 during height adjustment, avoiding structural jamming or uneven force due to rigid connection; at the same time, the symmetrical design of the hinges on both sides allows the mounting plate 2 to be subjected to uniform force during lifting and lowering, preventing excessive force on one side from causing the mounting plate 2 to tilt or deform, ensuring the overall structural stability of the device and extending its service life.

[0058] Both sides of the lower surface of the base frame 4 are fixedly connected with movable wheels 47;

[0059] Nurses do not need to carry the heavy base frame 4 and mounting plate 2. They can simply push the base frame 4 to transfer the device from one medical bed 1 to another, such as when a patient is transferred from a treatment bed to a rehabilitation bed, which greatly reduces physical exertion.

[0060] Working principle: During daily use, the synchronous motor 45 drives the bidirectional screw 42 in the storage slot 41 to rotate, causing the threaded sleeve 43 on the outer wall of the bidirectional screw 42 to move relative to each other, which in turn drives the hinge rod 44, which is hinged to the threaded sleeve 43, to rotate. Since the upper end of the hinge rod 44 is hinged to both sides of the lower surface of the mounting plate 2, the rotation of the hinge rod 44 can push the mounting plate 2 to rise and fall smoothly to meet different height requirements. The whole unit is placed above the medical bed 1, and the patient lies on the surface of the pad 3 on the mounting plate 2. The body is fixed by the Velcro fasteners on the upper restraint strap 32 and the lower restraint strap 33. The cuffs 34 allow the arms to extend naturally to ensure comfort. At this time, the groove 22 on the mounting plate 2 abuts against the rotating plate 21, providing stable support for the lying position. When it is necessary to turn over, the nursing staff starts the rotary motor 27 through the PLC control panel 212. The rotary motor 27 drives the turning frame 28 to rotate. The limiting groove 29 of the wall cooperates with the limiting blocks 211 on both sides of the slider 210 to guide the slider 210 to slide along a fixed trajectory, thereby driving the rotating plate 21 to rotate smoothly around the rotating connection of the mounting plate 2, realizing the patient's turning left or right. The limiting structure can prevent the slider 210 from disengaging and causing the turning to be interrupted. If it is necessary to adapt to different usage scenarios or adjust the patient's body position height, the synchronous motor 45 on the base frame 4 can be started through the PLC control panel 212. In addition, the universal wheels 11 on the lower surface of the medical bed 1 make it easy to push the bed to adjust its position as a whole (such as moving it closer to the nursing area or to the lighting area), and the moving wheels 47 on the lower surface of the base frame 4 make it easy to move the device between different medical beds 1 without carrying heavy parts. The whole process is centrally controlled through the PLC control panel 212 to realize the precise and convenient operation of each function, taking into account the stability of turning, the comfort of fixation and the flexibility of use.
