Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to a patient turning-over assistive device. Background Technology

[0002] In clinical treatment, some fracture patients suffer from severe traumatic injuries and often require prolonged bed rest. To prevent bedsores, lung infections, and circulatory disorders caused by prolonged bed rest, regular turning is necessary. However, routine manual turning or turning with simple assistive tools can easily apply uneven force to the fracture site, leading to fracture displacement, increased pain, and even hindering fracture healing. In severe cases, it may even cause secondary injury.

[0003] Some existing turning assist devices use air cushions or lifting structures to provide overall support and turning of patients, but they have the following shortcomings: First, most devices lack specialized support structures for relevant areas, making it impossible to achieve precise support and assistance; second, the turning angle adjustment method is relatively crude and lacks a stable control mechanism, which can easily lead to instability in the patient's posture; third, they lack height adjustment function, making it difficult to flexibly adjust the lifting height according to the patient's condition; and fourth, the devices are prone to problems such as tilting instability, air cushion displacement, or limited turning range during the turning process, affecting the actual use effect. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a patient-assisted turning device that can accurately adjust the angle and height, provide stable support, have good buffering and ventilation performance, and has a stable structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a patient-assisted turning device, including a hospital bed, wherein an installation groove is provided on the surface of the hospital bed corresponding to the pelvic bone position, a frame is fixed at the bottom of the hospital bed, the frame corresponds to the installation groove, and a lifting block is vertically slidably installed on the inner side of the frame;

[0006] The upper surface of the lifting block is provided with an arc-shaped groove, and the lower part of the lifting block is provided with a horizontal sliding groove. The sliding groove is connected to the bottom of the arc-shaped groove, and a toothed plate is slidably installed inside the sliding groove.

[0007] A support plate is installed inside the mounting groove, and an arc-shaped seat is provided at the bottom of the support plate. The arc-shaped seat is rotated and placed inside the arc-shaped groove, and the tilt angle of the support plate is controlled by rotating the arc-shaped seat.

[0008] Furthermore, sealing end caps are installed at both ends of the slide, and a threaded rod is rotatably installed between the two sealing end caps, with the toothed plate screwed onto the threaded rod.

[0009] Furthermore, the surface of the arc-shaped seat is uniformly provided with toothed grooves, which mesh with the toothed plate, and the upper surface of the support plate is uniformly provided with air cushions.

[0010] Furthermore, the upper surface of the lifting block is symmetrically provided with limiting blocks, and the two limiting blocks are respectively placed on both sides of the arc-shaped groove, and the two limiting blocks respectively limit the two sides of the arc-shaped seat.

[0011] Furthermore, a double screw is rotatably installed on the lower inner side of the frame, and sliders are symmetrically slidably installed inside the frame. The two sliders are respectively screwed onto different threaded surfaces of the double screw, and a knob is provided at the end of the double screw.

[0012] Furthermore, the top of the slider is hinged to a connecting rod, and the tops of both connecting rods are hinged to the bottom of the lifting block.

[0013] Furthermore, a hollow groove is provided on one side of the frame, and the ends of the double screws pass through the hollow groove and are equipped with knobs.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting mounting grooves on the surface of the hospital bed and combining them with a frame and lifting block structure, it is possible to locally lift and support the patient without moving the patient's overall position. This effectively reduces the direct traction and displacement force on the fracture site during traditional manual turning operations, reduces the risk of secondary injury, and improves the safety of the turning process.

[0016] By setting a groove in the lifting block and sliding a toothed plate therein, the toothed plate meshes with the toothed groove on the surface of the arc-shaped seat. In conjunction with the rotation control threaded rod, the angle of the support plate can be precisely adjusted, which effectively overcomes the problems of rough angle adjustment and unstable control of existing turning assist devices, and improves the stability of adjustment and the accuracy of patient position control.

[0017] By setting the arc-shaped seat at the bottom of the support plate to cooperate with the arc-shaped groove on the upper part of the lifting block, and setting limit blocks on both sides of the arc-shaped groove, the tilt angle of the support plate can be effectively limited, avoiding patient discomfort or equipment imbalance caused by excessive rotation during the turning process, and improving the stability of the equipment structure in dynamic adjustment.

[0018] By evenly distributing air cushion structures on the support plate, the cushioning properties of the air cushions are used to provide flexible support, and ventilation gaps are left between the air cushions to achieve local ventilation of the bed surface. This effectively solves the risk of bedsores and skin pressure problems caused by long-term bed rest for fracture patients, and enhances support comfort and breathability.

[0019] By setting up a twin screw and matching slider and linkage mechanism, the height of the lifting block can be adjusted, thereby achieving precise control of the overall height of the support plate. This solves the problem that existing devices lack vertical adjustment capability and cannot meet the needs of different patients. At the same time, the self-locking property of the threaded structure improves the reliability of the position after adjustment.

[0020] By incorporating a perforated groove and exposed knobs, operators can directly adjust the rotation of the threaded rod or twin screws without bending over or disassembling the structure, improving the ease of operation and nursing efficiency. This makes the equipment suitable for the high-frequency turning needs in clinical wards. Attached Figure Description

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] refer to Figures 1-5As shown, a patient-assisted turning device includes a hospital bed 1. A mounting groove 11 is formed on the surface of the hospital bed 1 corresponding to the pelvic bone position. The mounting groove 11 is used to embed structural components for assisting turning. A frame 12 is fixed to the bottom of the hospital bed 1. The frame 12 is an integral frame structure used to support the lifting and turning components. The frame 12 corresponds to the mounting groove 11, and a lifting block 4 is vertically slidably installed on the inner side of the frame 12. The lifting block 4 can move up and down vertically to adjust the overall height of the support plate 6, thereby allowing for fine-tuning operations to meet the patient's positional needs and improving nursing flexibility and comfort.

[0029] The upper surface of the lifting block 4 is provided with an arc-shaped groove 42, which cooperates with the bottom structure of the support plate 6 to limit the axial displacement of the support plate 6 during tilting. The lower interior of the lifting block 4 is provided with a horizontal sliding groove 41, which runs through both ends of the lifting block 4 and is used to embed the toothed plate 5 structure to realize the power transmission for angle adjustment. The bottom of the sliding groove 41 and the arc-shaped groove 42 are connected to facilitate the maintenance of structural integrity and spatial connectivity when the toothed plate 5 and the arc-shaped seat 61 are engaged. The toothed plate 5 is slidably installed inside the sliding groove 41. The toothed plate 5 moves horizontally in the sliding groove 41, thereby driving the arc-shaped seat 61 to rotate and realize the function of adjusting the flip angle of the support plate 6.

[0030] A support plate 6 is installed inside the mounting groove 11. The support plate 6 has an arc-shaped structure and fits against the pelvic area to provide specialized support for the patient. An arc-shaped seat 61 is provided at the bottom of the support plate 6. The arc of the arc-shaped seat 61 matches the groove 42 and is nested and rotated inside the arc-shaped groove 42 to provide a reliable guide fulcrum during turning. The tilt angle of the support plate 6 can be controlled by rotating the arc-shaped seat 61. Combined with the air cushion 63, it can play a role in cushioning, preventing pressure sores and ventilation, while improving the stability of turning.

[0031] refer to Figures 3-5 As shown, sealing end caps 44 are installed at both ends of the slide groove 41. The sealing end caps 44 close the slide groove opening to prevent external impurities from entering and affecting the sliding of the toothed plate 5. A threaded rod 45 is rotatably installed between the two sealing end caps 44. The threaded rod 45 passes through the interior of the slide groove 41 and drives the toothed plate 5 to move horizontally by rotation. The toothed plate 5 is screwed onto the threaded rod 45. By adjusting the threaded rod 45, the toothed plate 5 can be linearly driven, thereby indirectly realizing the rotation of the arc-shaped seat 61 and achieving the purpose of adjusting the angle of the support plate 6.

[0032] refer to Figures 3-5As shown, the surface of the arc-shaped seat 61 is uniformly provided with toothed grooves 62, which are used to mesh with the toothed plate 5. The meshing structure allows the translation of the toothed plate 5 to be converted into the rotation of the arc-shaped seat 61. The toothed grooves 62 are evenly distributed to ensure stable meshing during rotation, thereby improving the control accuracy and safety during the turning process. The upper surface of the support plate 6 is uniformly provided with air cushions 63. The air cushions 63 are arranged side by side. After each air cushion is inflated independently, it can provide uniform support. There are ventilation gaps between them to enhance ventilation and pressure relief, which helps to reduce the risk of bedsores caused by long-term bed rest.

[0033] refer to Figure 4 As shown, limit blocks 43 are symmetrically arranged on the upper surface of the lifting block 4. The limit blocks 43 are located on both sides of the arc-shaped groove 42, serving as the limiting boundary for the rotation of the arc-shaped seat 61 and restricting its rotation range. The two limit blocks 43 are respectively placed on both sides of the arc-shaped groove 42, and the two limit blocks 43 limit the arc-shaped seat 61 on both sides. During the turning process, they play a role in stabilizing the structure and preventing excessive rotation, thereby ensuring operational safety and precise angle control.

[0034] refer to Figure 3 As shown, a double screw 13 is rotatably mounted on the lower inner side of the frame 12. The outer surface of the double screw 13 is provided with left-hand and right-hand threads, which cooperate with the two sliders 2 to form a relative driving structure. Slider 2 is symmetrically slidably mounted inside the frame 12. The sliders 2 are respectively mounted on the two threaded surfaces of the double screw 13, so that the two sliders 2 can move symmetrically away from or towards each other by rotating the double screw 13. A knob is provided at the end of the double screw 13. The knob is used to control the rotation of the double screw 13. The mechanical self-locking characteristic keeps the tilting support height stable and unchanged, improving the safety and reliability of the device.

[0035] refer to Figure 3 As shown, a connecting rod 3 is hinged to the top of the slider 2. The connecting rod 3 is a rigid connecting part. One end of the connecting rod is movably connected to the slider 2, and the other end is connected to the lifting block 4 to form a height transmission structure. The tops of the two connecting rods 3 are both hinged to the bottom of the lifting block 4. Rotating the double screw 13 can drive the two sliders 2 to move simultaneously. The lifting block 4 is driven to rise and fall as a whole through the linkage of the connecting rods 3, so as to realize the vertical lifting assistance function for the patient.

[0036] refer to Figure 3 As shown, a perforated groove 121 is provided on one side of the frame 12. The perforated groove 121 is used to provide operating space so that the knob at the end of the double screw 13 can be easily adjusted from the outside. The end of the double screw 13 passes through the perforated groove 121 and is equipped with a knob. The operator can directly control the overall height of the support plate 6 through the knob, thereby realizing the adjustment of the patient's position and optimization of comfort, effectively meeting the needs of clinical nursing and turning assistance.

[0037] The working principle of this utility model is as follows: The patient lies flat on the upper surface of the bed 1, with the pelvic bone positioned on the surface of the support plate 6, supported by multiple air cushions 63. The air cushions 63 can act as a buffer, and the gaps between the multiple air cushions 63 can provide ventilation. In the initial state, the upper surface of the support plate 6 is flush with the bed 1. When it is necessary to turn over, the support plate 6 can be adjusted to tilt, thereby assisting in turning over. During adjustment, the knob at the end of the threaded rod 45 can be rotated to control the rotation of the threaded rod 45, which in turn controls the toothed plate 5 to move laterally inside the slide groove 41. Through the meshing of the toothed plate 5 and the toothed groove 62, the arc-shaped seat 61 is rotated, thereby tilting the support plate 6. The limiting block 43 can effectively limit the two sides of the arc-shaped seat 61 to ensure its stability during rotation, thereby achieving the purpose of assisting the patient to turn over.

[0038] Rotating the knob at the end of the twin screw 13 allows the two sliders 2 to move relative to each other using the different bolt surfaces. This, in turn, controls the height of the lifting block 4 via the connecting rod 3, thereby controlling the height of the support plate 6. This lifts the patient's pelvis and lumbar spine. Both the angle and height of the support plate 6 are adjusted using the self-locking property of the threads, which improves the stability of the equipment during use.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
