Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an assistive device for turning over in bed after spinal surgery. Background Technology

[0002] Post-spinal surgery patients require prolonged bed rest for rehabilitation. Due to limited post-operative mobility, turning over is difficult, easily leading to complications such as bedsores and muscle atrophy. Therefore, designing a bed device that can assist patients in turning over, expose wounds, and provide good ventilation is of great significance for improving patient rehabilitation outcomes and nursing efficiency.

[0003] However, traditional turning devices often employ electric drives or complex mechanical structures, resulting in high costs and complicated operation, making them unsuitable for home use or small to medium-sized medical institutions. While some devices can achieve basic turning functions, they lack effective design in terms of wound exposure and ventilation, leading to inconvenient nursing operations and affecting patient comfort and recovery outcomes. Furthermore, the length adjustment function of existing devices is generally not flexible enough to fully accommodate the needs of patients of different heights, and some operating parts of these devices pose safety hazards to patients or medical staff. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bed-turning assistance device for spinal surgery. The device uses a moving block to drive a second moving rod to the left, which in turn drives a first moving rod to the right via gear transmission, rotating the second bed board to expose the patient's wound for easier cleaning and ventilation. The bed frame length can be adjusted by rotating a handle to accommodate patients of different heights, and the handle can be retracted to prevent tripping, thus improving safety and convenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bed-turning assistance device for spinal surgery, comprising a bed frame, a first bed board at the upper end of the bed frame, a fixed block fixedly connected to the lower end of the bed frame, a fixed rod fixedly connected to the lower end of the fixed block, a hydraulic rod rotatably connected to the outer wall of the fixed rod, a driving end of the hydraulic rod rotatably connected to the lower end of the first bed board, a second bed board on the inner side of the first bed board, a first moving rod slidably connected to the left end of the inner wall of the second bed board, a first spring provided at the right end of the first moving rod, a second moving rod connected to the lower end of the first moving rod via a meshing assembly, a second spring provided to the left end of the second moving rod, a moving block fixedly connected to the lower end of the second moving rod, a threaded rod threadedly connected to the middle of the bed frame, a handle connected to the right end of the threaded rod via a sliding assembly, an extension rod slidably connected to the inner wall of the right end of the bed frame, and casters provided at the lower end of the bed frame.

[0006] Furthermore, the meshing assembly includes a first rack fixedly connected to the lower side of the right end of the first moving rod, a gear meshing with the lower end of the first rack, a second rack meshing with the lower end of the gear, and the second rack fixedly connected to the upper side of the left end of the second moving rod.

[0007] Furthermore, the sliding assembly includes a fixed disc fixedly connected to the right end of the threaded rod, a pin fixedly connected to the left end of the fixed disc, a collar slidably connected to the outer wall of the pin, and a handle fixedly connected to the lower end of the collar.

[0008] Furthermore, the right end of the first spring is connected to the inner wall of the second bed plate, the left end of the second spring is connected to the inner wall of the second bed plate, and the second bed plate and the gear are rotatably connected.

[0009] Furthermore, the first movable rod and the first bed board are slidably connected, and the second movable rod and the first bed board are also slidably connected.

[0010] Furthermore, the collar is fitted onto the outer wall of the right end of the threaded rod.

[0011] Furthermore, the left end of the threaded rod is threadedly connected to the bed frame, while the right end of the threaded rod is rotatably connected to the bed frame.

[0012] Furthermore, a first mattress is provided on the upper end of the first bed board, and a second mattress is provided on the upper end of the second bed board.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this invention, by sliding the moving block to the left, the second moving rod moves synchronously to the left, thereby compressing the second spring. The movement of the second moving rod then causes the second rack connected to it to move to the left. Through gear transmission, this causes the first rack meshing with it to move to the right, so that the first moving rod slides to the right while compressing the first spring. Since the rear end of the second bed board is also hinged to the first bed board, the second bed board can rotate downwards after the first and second moving rods slide out of the first bed board. At this time, the second mattress can be removed, and the patient's wound can be fully exposed, facilitating cleaning and examination by medical staff, and also promoting ventilation and perspiration for the patient.

[0015] 2. In this invention, rotating the handle drives the collar and pin to rotate, which in turn rotates the fixed plate, thereby driving the threaded rod to rotate. Under the action of the threaded connection, the right end of the bed frame will move to the right, and the extension rod will slide out simultaneously, thus meeting the usage needs of patients of different heights. When there is no need to adjust the length of the bed frame, push the handle to the left to disengage the collar from the pin, then turn the handle to the bottom and move it to the left to store the handle under the bed frame, preventing people from tripping while walking and improving the safety and convenience of use.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a bed-turning assistance device for spinal surgery, comprising a bed frame 1, a first bed board 2 at the upper end of the bed frame 1, a fixing block 5 fixedly connected to the lower end of the bed frame 1, a fixing rod 6 fixedly connected to the lower end of the fixing block 5, a hydraulic rod 7 rotatably connected to the outer wall of the fixing rod 6, the driving end of the hydraulic rod 7 rotatably connected to the lower end of the first bed board 2, a second bed board 8 on the inner side of the first bed board 2, a first mattress 3 at the upper end of the first bed board 2, a second mattress 4 at the upper end of the second bed board 8, a first moving rod 9 slidably connected to the left end of the inner wall of the second bed board 8, and a first spring 10 fixedly connected to the right end of the first moving rod 9. The first moving rod 9 has a first rack 11 on the lower right side. The lower end of the first rack 11 is meshed with a gear 12. The lower end of the gear 12 is meshed with a second rack 14. The second rack 14 is fixedly connected to the upper left side of the second moving rod 15. The left end of the second moving rod 15 is provided with a second spring 13. The right end of the first spring 10 is connected to the inner wall of the second bed board 8. The left end of the second spring 13 is connected to the inner wall of the second bed board 8. The second bed board 8 and the gear 12 are rotatably connected. The first moving rod 9 and the first bed board 2 are slidably connected. The second moving rod 15 and the first bed board 2 are slidably connected. The lower end of the second moving rod 15 is fixedly connected to a moving block 16.

[0025] The specific bed frame 1 is equipped with two first bed boards 2 connected by hinges. When the hydraulic rod 7 is activated, its drive end pushes the first bed board 2 to rotate upward around the hinge, thereby enabling the patient to turn over. At this time, the sliding block 16 moves to the left, causing the second moving rod 15 to move to the left simultaneously, thereby compressing the second spring 13. The movement of the second moving rod 15 causes the second rack 14 connected to it to move to the left. Through the transmission of the gear 12, it drives the first rack 11 meshing with it to move to the right, so that the first moving rod 9 slides to the right while compressing the first spring 10. Since the rear end of the second bed board 8 is also connected to the first bed board 2 by hinges, when the first moving rod 9 and the second moving rod 15 slide out of the first bed board 2, the second bed board 8 can rotate downward. At this time, the second mattress 4 can be removed, and the patient's wound can be fully exposed, which is convenient for medical staff to clean and examine, and also facilitates ventilation and perspiration for the patient.

[0026] Reference Figure 4 and Figure 5 A threaded rod 17 is threadedly connected to the middle of the bed frame 1. The left end of the threaded rod 17 is threadedly connected to the bed frame 1, and the right end of the threaded rod 17 is rotatably connected to the bed frame 1. A fixed plate 21 is fixedly connected to the right end of the threaded rod 17. A pin 20 is fixedly connected to the left end of the fixed plate 21. A collar 18 is slidably connected to the outer wall of the pin 20. The collar 18 is sleeved on the outer wall of the right end of the threaded rod 17. A handle 19 is fixedly connected to the lower end of the collar 18. An extension rod 22 is slidably connected to the inner wall of the right end of the bed frame 1. A caster wheel 23 is provided at the lower end of the bed frame 1.

[0027] Specifically, the bed frame 1 also features a length adjustment function. Turning the handle 19 rotates the collar 18 and pin 20, causing the fixing plate 21 to rotate, which in turn drives the threaded rod 17 to rotate. Under the action of the threaded connection, the right end of the bed frame 1 moves to the right, and the extension rod 22 slides out simultaneously, thus meeting the needs of patients of different heights. When there is no need to adjust the length of the bed frame 1, push the handle 19 to the left to disengage the collar 18 from the pin 20. Then turn the handle 19 to its lowest position and move it to the left to retract the handle 19 under the bed frame 1, preventing tripping and improving safety and convenience.

[0028] Working principle: In use, the hydraulic rod 7 is activated, and its drive end pushes the first bed board 2 to rotate upward around the hinge, thus enabling the patient to turn over. Subsequently, the sliding block 16 slides to the left, causing the second sliding rod 15 to move to the left and compress the second spring 13. The movement of the second sliding rod 15 further drives the second rack 14 to move to the left, and the gear 12 meshing with it rotates clockwise, thereby driving the first rack 11 to move to the right. The rightward movement of the first rack 11 drives the first sliding rod 9 to move to the right and compresses the first spring 10. Since the rear end of the second bed board 8 is also connected to the first bed board 2 via a hinge, when the first sliding rod 9 and the second sliding rod 15 slide out of the first bed board 2, the second bed board 8 can rotate downward. At this time, the second mattress 4 can be removed, and the patient's wound can be fully exposed. In addition, the bed frame 1 is also designed with a length adjustment function. By rotating handle 19, the handle 19 drives the collar 18 to rotate, which in turn drives the pin 20 to rotate. The fixed plate 21 rotates accordingly, thereby driving the threaded rod 17 to rotate. Under the action of the threaded connection, the right end of the bed frame 1 moves to the right, and the extension rod 22 slides out, thus extending the bed frame 1. This design is suitable for patients of different heights and provides better adaptability. When it is not necessary to adjust the length of the bed frame 1, move handle 19 to the left to disengage the collar 18 from the pin 20, so that handle 19 can be turned to the bottom. Then move handle 19 to the left again to store it at the bottom of the bed frame 1.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
