DETAILED DESCRIPTION

[0019] It is easy to understand that, according to the technical solutions of the present application, those skilled in the art can propose various structures and implementation modes that can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solutions of the present application, and should not be regarded as the whole or as a limitation or restriction on the technical solutions of the present application.

[0020] Referring to Figures 1 to 7 As shown in the drawings, the present application provides a technical solution: a femoral neck fracture patient turning over aid, comprising a base 1, the upper part of the base 1 is provided with two flat plate air bags 2, the inside of the base 1 is provided with a lifting assembly 3, the side of the lifting assembly 3 is provided with a mounting assembly 4, the upper part of the flat plate air bag 2 is provided with a protection assembly 5, the outer surface of the flat plate air bag 2 is fixedly connected with a catheter 6.

[0021] After the device is exhausted, it is placed on the sickbed, the patient lies on the upper part of the flat plate air bag 2, the device can be fixed on the guardrails on both sides of the sickbed through the mounting assembly 4, when turning over is needed, inflation is carried out through the catheter 6, the protection assembly 5 can wrap and protect the two sides of the patient, and the lifting assembly 3 can be used to assist the patient to turn over.

[0022] Referring to Figure 2 and Figure 3 As shown in the drawings, the lifting assembly 3 comprises a push plate 31 rotatably connected in the inside of the base 1, the inner wall of the base 1 is provided with a support 32, the middle part of the support 32 is rotatably connected with a warped plate 33, the end of the warped plate 33 extending out of the base 1 is movably provided with a bolt rod 35, the outer surface of the bolt rod 35 is threadedly sleeved with a threaded seat 36, the middle part of the base 1 is fixedly connected with a partition belt 7, the two flat plate air bags 2 are symmetrically distributed on both sides of the partition belt 7, the push plate 31 is fixedly connected to the lower surface of the flat plate air bag 2, the lower surface of the push plate 31 is provided with a movable groove 34, the end of the warped plate 33 extending into the base 1 is movably clamped in the inside of the movable groove 34, the end of the warped plate 33 extending out of the base 1 is provided with an opening, the inner wall of the opening is provided with a limiting groove 37, the bottom end of the bolt rod 35 is rotatably connected with a limiting seat 38, the two sides of the limiting seat 38 are slidably connected in the limiting groove 37.

[0023] The operator rotates the bolt rod 35, causing it to move vertically downwards along the axis of the threaded seat 36. Simultaneously, the limiting seat 38 moves downwards as well. Because the limiting seat 38 and the bolt rod 35 are rotatably connected, and the two sides of the limiting seat 38 are slidably engaged in the limiting groove 37, this structural design can effectively avoid motion interference between components, ensuring the stability and smoothness of the transmission process. The downward force of the bolt rod 35 will push the rocker plate 33 to rotate smoothly around the support 32. The other end of the rocker plate 33 will then tilt upwards and slide smoothly in the movable groove 34, pushing the push plate 31 to flip upwards. The push plate 31 then applies force smoothly to the patient's body, thereby pushing the patient to complete the lateral roll, achieving the effect of mechanically assisted turning. The entire process is characterized by uniform force and controllable movement, requiring no effort from the patient. This reduces the physical exertion of caregivers and allows for control of the turning angle, avoiding sudden swaying. It is suitable for the rehabilitation needs of patients with femoral neck fractures who are bedridden and immobilized, significantly improving the safety and convenience of assisted turning operations.

[0024] Reference Figures 3 to 5 As shown, the mounting assembly 4 includes a first hoop plate 41 fixedly connected to the outer surface of the threaded seat 36. A pin 43 is fixedly connected to the outer surface of the first hoop plate 41. A second hoop plate 42 is sleeved on the outer surface of the pin 43. A sleeve plate 44 is movably sleeved on the outer surface of the pin 43. Two retaining plates 46 are slidably connected to the middle of the sleeve plate 44. A first spring 47 is provided inside the sleeve plate 44. Both ends of the first spring 47 are fixedly connected to the outer surface of the retaining plate 46. A retaining groove 45 is opened on the outer surface of the pin 43. The retaining plate 46 is engaged inside the retaining groove 45.

[0025] The first hoop plates 41 on both sides of the device are attached to the outside of the guardrail on the side of the hospital bed. Then, the second hoop plate 42 is aligned with the pin 43 and attached to the outside of the first hoop plate 41 to achieve double-layer wrapping and positioning of the bed guardrail. Next, the sleeve plate 44 is aligned with the pin 43 and slowly fitted onto its outer surface. The two locking plates 46 are pressed towards the middle of the sleeve plate 44, so that the locking plates 46 are close to each other and squeeze the internal first spring 47. After the limiting obstruction of the locking plates 46 is released, the sleeve plate 44 can be completely fitted into the pin 43. After the sleeve plate 44 and the second hoop plate 42 are tightly fitted, the locking plates 46 are released. The first spring 47 pushes the locking plates 46 precisely into the slot 45 by the rebound force, completing the double hoop plate's firm locking of the guardrail. This structure is simple in design, requires no special tools throughout the process, and the operation steps are intuitive and easy to understand. It simplifies the disassembly and assembly process of the device and the hospital bed, effectively improves the efficiency of disassembly and assembly, and achieves a stable locking of the guardrail, preventing displacement of the device during use and ensuring the stability of subsequent auxiliary operations.

[0026] Reference Figure 2 , Figure 6 and Figure 7As shown, the protective component 5 includes a side airbag 51 fixedly connected to the upper surface of the flat airbag 2. A ventilation adjustment mechanism 52 is fixedly connected to the outer surface of the side airbag 51. An arc-shaped airbag 53 is fixedly connected to the end of the ventilation adjustment mechanism 52 away from the side airbag 51. The ventilation adjustment mechanism 52 includes a sleeve 521 fixedly connected to the outer surface of the side airbag 51. An inner tube 522 is movably inserted into the end of the sleeve 521 away from the side airbag 51. The end of the inner tube 522 extending out of the sleeve 521 is fixedly connected to the side of the arc-shaped airbag 53. A sealing piston 523 is fixedly fitted at the end of the inner tube 522 that extends into the sleeve 521. A second spring 524 is fitted on the outer surface of the inner tube 522.

[0027] When a patient needs to be turned over, the air tube at the end of one of the flat airbags 2 is inflated, causing that side of the flat airbag 2 to expand and generate the driving force for turning over. The other side of the flat airbag 2 is only slightly inflated, creating a flexible buffer support surface to prevent the patient's body from suddenly shaking due to excessive force on one side, ensuring a smooth and gentle turning process. After inflation, the gas flows into the side airbag 51 simultaneously, and then through the ventilation adjustment mechanism 52 to inflate the arc-shaped airbag 53, forming a three-dimensional wrap-around protection for both sides of the patient's body. For patients of different body types, after the arc-shaped airbag 53 wraps around the side, the inner tube 522 can flexibly extend and retract under the elastic force of the second spring 524 to precisely fit the body contour, which not only prevents the affected limb from shifting and causing secondary injury during turning over, but also improves the fit and comfort of the patient's limb, adapting to diverse nursing needs.

[0028] Working principle: After the device is depressurized, it is placed on the hospital bed. The patient lies on the upper part of the flat airbag 2. The first hoop plates 41 on both sides are attached to the side rails of the hospital bed. Then, the second hoop plate 42 is aligned with the pin 43 and attached to the outside of the first hoop plate 41, wrapping the rails inside. Then, the sleeve plate 44 is aligned and fitted onto the outer surface of the pin 43. The two locking plates 46 are pressed towards the middle of the sleeve plate 44, so that the two locking plates 46 come closer to each other and squeeze the first spring 47. After the locking plates 46 are removed, the sleeve plate 44 is completely fitted onto the outer surface of the pin 43. After the sleeve plate 44 and the second hoop plate 42 are attached, the locking plates 46 are released. Under the action of the rebound force of the first spring 47, the locking plates 46 are pushed into the slot 45, realizing the locking of the rails by the first hoop plate 41 and the second hoop plate 42. The structure is simple and easy to operate, improving the efficiency of disassembly and assembly. When the patient needs to turn over, the air tube at the end of one of the flat airbags 2 is inflated, causing one side of the flat airbag 2 to inflate, while the other side of the flat airbag 2 can be inflated only slightly to provide a cushioning effect. After inflation, the airbag 2 flows synchronously into the side airbag 51, and then enters the arc-shaped airbag 53 through the ventilation adjustment mechanism 52 to wrap and protect the patient's sides. In addition, for patients of different body types, after the arc-shaped airbag 53 wraps around the patient's sides, the inner tube 522 can be extended and retracted under the elastic force of the second spring 524 to ensure that patients of different body types are wrapped and protected. The operator rotates the bolt rod 35, causing it to move downwards along the axis of the threaded seat 36. Simultaneously, this pushes the limiting seat 38 downwards. Since the limiting seat 38 and the bolt rod 35 are rotatably connected, and both sides of the limiting seat 38 are slidably engaged in the limiting groove 37 to avoid movement interference, rotating the bolt rod 35 will push the rocker plate 33 to rotate around the support 32. The other end of the rocker plate 33 tilts upwards and slides in the movable groove 34, while also pushing the push plate 31 to flip upwards, thereby pushing the patient to turn sideways, thus achieving the effect of assisting in turning over.

[0029] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
