Description

Technical Field

[0001] This utility model relates to the field of turning beds, and more specifically, to a turning drive structure for a neurological nursing turning bed. Background Technology

[0002] In neurological nursing, patients often require prolonged bed rest due to limited physical function. Regular turning and appropriate getting up are crucial for preventing complications and promoting recovery. Currently, there are many shortcomings in the clinical nursing equipment for bedridden patients.

[0003] Existing nursing turning beds are often bulky and lack flexible movement mechanisms. Adjusting patient positions or transferring patients often requires multiple nurses to work together, which is not only physically and time-consuming but also increases the risk of secondary injury due to shaking during transport. Furthermore, traditional moving parts are often unstable, potentially loosening or separating during movement, posing safety hazards. Traditional turning and lifting operations rely heavily on manual labor, which is not only physically demanding but also makes it difficult to precisely control the angle and force of the turn. Prolonged manual operation can lead to nurse fatigue, affecting the effectiveness of turning and lifting, and increasing the risk of pressure sores and lung infections in patients. While some electric turning devices reduce the workload to some extent, they still lack precision and flexibility, failing to meet the personalized care needs of patients. Therefore, we propose an improvement: a turning drive structure for a neurology nursing turning bed. Utility Model Content

[0004] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: a turning drive structure for a neurology nursing turning bed, including a drive structure base plate. Each of the four corners of the bottom of the drive structure base plate is provided with a movable wheel frame. An L-shaped connecting plate is installed between the drive structure base plate and the movable wheel frames. A circular hole is provided on the outer plate of the L-shaped connecting plate, and a fixed shaft is inserted into the circular hole. The bottom of the fixed shaft is embedded in a groove at the bottom of the movable wheel frame. A rotatable caster wheel is rotatably connected inside the movable wheel frame.

[0005] As a preferred technical solution of this utility model, the movable wheel frame has a rotating shaft running through it laterally, and the movable universal wheel is installed in the movable wheel frame through the rotating shaft.

[0006] As a preferred technical solution of this utility model, support rods are provided on both sides above the base plate of the drive structure, and a drive structure turning bed is welded to the top of the support rods.

[0007] As a preferred technical solution of this utility model, the drive structure turning bed is provided with a turning bed board, and the turning left bed board and the turning right bed board are installed on the two rotating shafts of the drive structure turning bed.

[0008] As a preferred technical solution of this utility model, a lifting driving hydraulic cylinder is linked to the bottom of the turning bed of the driving structure, and a lifting driving hydraulic rod is slidably connected inside the lifting driving hydraulic cylinder. The turning bed board and the lifting driving hydraulic rod are connected by a linkage rod.

[0009] As a preferred technical solution of this utility model, linkage blocks are installed on both sides of the drive structure base plate. There are two linkage blocks, and a left turning drive hydraulic cylinder and a right turning drive hydraulic cylinder are respectively connected above the linkage blocks.

[0010] As a preferred technical solution of this utility model, the left turning driving hydraulic cylinder is internally slidably connected to a left turning driving hydraulic rod, and the left turning bed plate is linked to the left turning driving hydraulic rod.

[0011] As a preferred technical solution of this utility model, the right turning drive hydraulic cylinder is internally slidably connected with a right turning drive hydraulic rod, and the right turning bed plate is linked to the right turning drive hydraulic rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The bottom four corners of the drive structure base plate of this utility model are equipped with omnidirectional casters. With the characteristic of being able to rotate in all directions, nursing staff can easily move the turning bed to any position in the ward without having to spend a lot of physical effort to move and adjust it, thus improving the efficiency of nursing work. It is especially suitable for situations where the patient's position needs to be frequently adjusted or the patient needs to be transferred.

[0013] Stable connection ensures safe movement: The L-shaped connecting plate and fixed shaft design guarantee the stability of the connection between the drive structure base plate and the moving wheel frame. During movement, even if the ground is uneven or there is a slight collision, it can effectively prevent the moving wheel frame from separating from the drive structure base plate or from shaking, ensuring the safety of the patient during movement and avoiding accidents caused by unstable connection.

[0014] This utility model of a turning bed board achieves the function of turning over by using a hydraulic cylinder and a hydraulic rod to drive the patient's movement. For neurological patients, especially those who are bedridden for extended periods, an appropriate sitting-up posture helps promote blood circulation, improve respiratory function, and prevent pulmonary infection complications. Nursing staff can precisely control the turning angle of the bed board according to the patient's rehabilitation needs and physical condition, providing a comfortable sitting-up experience and benefiting the patient's rehabilitation treatment.

[0015] This invention utilizes a left-turning drive hydraulic cylinder and a right-turning drive hydraulic rod to control the rotation of the left and right bed boards, respectively. Regularly turning patients is crucial for preventing pressure ulcers. This turning drive structure easily enables patients to turn left and right smoothly and at controllable angles. Compared to traditional manual turning, it not only reduces the workload of caregivers but also allows for more precise control of turning force and angle, effectively reducing friction and pressure on the patient's skin and lowering the risk of pressure ulcers.

[0016] This utility model's turning drive structure adopts a modular design concept. Various components, such as the drive structure base plate, support rods, and drive hydraulic cylinders, are connected through inlay, welding, and linkage plates, facilitating installation and disassembly. When the equipment malfunctions or requires regular maintenance, caregivers or repair personnel can quickly locate and replace damaged parts, reducing maintenance time and costs and improving equipment efficiency.

[0017] The design of this utility model features a compact overall turning and lifting mechanism with a rational layout of components. While fulfilling the functions of turning and getting up, it minimizes the space occupied in the ward. This is particularly important for neurology wards with limited space, providing patients and nursing staff with more spacious activity areas and improving ward utilization efficiency.

[0018] This invention utilizes a hydraulic drive system, allowing caregivers to precisely control the raising and turning movements of the bed board, adjusting the speed, force, and angle of the movements according to the patient's specific condition. This precise control better meets the individualized needs of patients, improves the targetedness and effectiveness of nursing care, and provides patients with higher-quality nursing services.

[0019] Traditional patient turning and sitting operations often require multiple nurses working together, which is labor-intensive and can easily cause physical injury to nurses. The application of this turning-over drive structure allows nurses to simply operate a control switch to turn and sit patients, greatly reducing their workload and allowing them to devote more energy to patient observation and other nursing care.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1: A turning drive structure for a neurology nursing turning bed includes a drive structure base plate 1. Four movable wheel frames 2 are respectively provided at the four corners of the bottom of the drive structure base plate 1. An L-shaped connecting plate 3 is installed between the drive structure base plate 1 and the movable wheel frames 2. A circular hole is provided on the outer plate of the L-shaped connecting plate 3, and a fixed shaft 4 is inserted into the circular hole. The bottom of the fixed shaft 4 is embedded in a groove at the bottom of the movable wheel frame 2. A movable universal wheel 5 is rotatably connected inside the movable wheel frame 2. A rotating shaft 6 extends laterally through the movable wheel frame 2, and the movable universal wheel 5 is installed inside the movable wheel frame 2 through the rotating shaft 6. Support rods 7 are provided on both sides above the drive structure base plate 1, and a drive structure turning bed 8 is welded to the top of the support rods 7.

[0031] The drive structure turning bed 8 is equipped with a turning bed board 9, and a turning left bed board 10 and a turning right bed board 11 are mounted on the two side pivots of the drive structure turning bed 8. A lifting drive hydraulic cylinder 12 is linked to the bottom of the drive structure turning bed 8, and a lifting drive hydraulic rod 13 is slidably connected inside the lifting drive hydraulic cylinder 12. The turning bed board 9 and the lifting drive hydraulic rod 13 are connected by a linkage rod. Linkage blocks 14 are installed on both sides of the drive structure base plate 1. There are two linkage blocks 14, and the left turning drive hydraulic cylinder 15 and the right turning drive hydraulic cylinder 17 are respectively connected above the linkage blocks 14.

[0032] The left turning drive hydraulic cylinder 15 is internally slidably connected to the left turning drive hydraulic rod 16, and the left turning bed plate 10 is linked to the left turning drive hydraulic rod 16. The right turning drive hydraulic cylinder 17 is internally slidably connected to the right turning drive hydraulic rod 18, and the right turning bed plate 11 is linked to the right turning drive hydraulic rod 18.

[0033] The working principle of the neurology nursing turning bed: The bottom of the drive structure base plate 1 has four corners equipped with movable wheel frames 2, which are connected to the drive structure base plate 1 and the movable wheel frames 2 via L-shaped connecting plates 3 and fixed shafts 4. Movable casters 5 are installed inside the movable wheel frames 2 via rotating shafts 6, enabling flexible movement and directional adjustment of the bed. Support rods 7 are installed on both sides above the drive structure base plate 1, and the drive structure turning bed 8 is welded to the top of the support rods 7, forming a stable support frame. The drive structure turning bed 8 has a turning bed board 9, and a left turning bed board 10 and a right turning bed board 11 are installed on both sides via rotating shafts.

[0034] The left-turning drive hydraulic cylinder 15 has a left-turning drive hydraulic rod 16 internally connected and connected to the left turning bed board 10 via a linkage plate. When the left-turning drive hydraulic rod 16 extends or retracts, it causes the left turning bed board 10 to flip, thus achieving the left-side turning function. The right-turning drive hydraulic cylinder 17 has a right-turning drive hydraulic rod 18 internally connected and connected to the right turning bed board 11 via a linkage plate. When the right-turning drive hydraulic rod 18 extends or retracts, it causes the right turning bed board 11 to flip, thus achieving the right-side turning function.

[0035] A lifting-drive hydraulic cylinder 12 is connected to the underside of the turning bed 8, and a lifting-drive hydraulic rod 13 is slidably connected inside the cylinder. The lifting-drive hydraulic rod 13 is connected to the turning bed board 9 via a linkage rod. When the lifting-drive hydraulic rod 13 extends or retracts, it pushes the turning bed board 9 to tilt, assisting the patient in completing the lifting action.

[0036] Linkage blocks 14 are installed on both sides of the drive structure base plate 1 to fix the left turning drive hydraulic cylinder 15 and the right turning drive hydraulic cylinder 17, ensuring the stability of the turning drive system. Through precise control of the hydraulic system, the components work together to realize automatic turning and getting up of patients, reducing the workload of nursing staff and improving patient comfort.

[0037] The working process of the turning drive structure of the neurology nursing turning bed: using casters for movement: the nurse pushes the base plate 1 of the drive structure. Since the casters 5 are installed in the caster frame 2 at the four corners of the bottom of the base plate 1 through the rotating shaft 6, the casters 5 can rotate flexibly, so that the entire turning drive structure can move easily in all directions.

[0038] Stable connection ensures safe movement: During movement, the fixed shaft 4 inserted into the round hole of the outer plate of the L-shaped connecting plate 3 is embedded in the bottom groove of the moving wheel frame 2, which ensures the stability of the connection between the drive structure base plate 1 and the moving wheel frame 2, avoids shaking or separation during movement, and ensures safe movement.

[0039] Activate the standing-up drive device: When it is necessary for the patient to get up from the turning bed, the nursing staff operates the control switch of the standing-up drive hydraulic cylinder 12 to start it working.

[0040] The sliding of the hydraulic rod drives the movement of the bed board: The lifting driving hydraulic rod 13 inside the lifting driving hydraulic cylinder 12 begins to slide. Since the turning bed board 9 and the lifting driving hydraulic rod 13 are connected by a linkage rod, the sliding of the lifting driving hydraulic rod 13 is transmitted to the turning bed board 9 through the linkage rod, thereby driving the turning bed board 9 to gradually rise, allowing the patient to reach a suitable sitting angle.

[0041] The process of falling back down: When the patient needs to lie down to rest, the control switch of the hydraulic cylinder 12 for rising is operated in the opposite direction, the hydraulic rod 13 for rising slides in the opposite direction, and the turning bed board 9 is driven back to the initial lying position through the linkage rod.

[0042] Start the left turning drive device: The caregiver operates the control switch of the left turning drive hydraulic cylinder 15 to start it working.

[0043] The left turning hydraulic rod drives the left bed board to turn: The left turning driving hydraulic rod 16 inside the left turning driving hydraulic cylinder 15 begins to slide. Since the left turning bed board 10 and the left turning driving hydraulic rod 16 are linked, the sliding of the left turning driving hydraulic rod 16 will cause the left turning bed board 10 to turn upwards at a certain angle.

[0044] To complete the leftward roll: As the left bed board 10 is rotated, the patient's body will tilt to the left, thus achieving the leftward roll.

[0045] Start the right-turning drive device: The nursing staff operates the control switch of the right-turning drive hydraulic cylinder 17 to start it working.

[0046] The right-turning hydraulic rod drives the right bed board to turn: The right-turning driving hydraulic rod 18 inside the right-turning driving hydraulic cylinder 17 begins to slide. Since the right bed board 11 and the right-turning driving hydraulic rod 18 are linked, the sliding of the right-turning driving hydraulic rod 18 will cause the right bed board 11 to turn upwards at a certain angle.

[0047] To complete the rightward roll: As the right bed board 11 is rotated, the patient's body will tilt to the right, thus achieving the rightward roll.

[0048] Through the coordinated operation of the above processes, the turning drive structure of this neurology nursing turning bed can meet the patient's needs for movement, getting up, and turning over during the nursing process.

[0049] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
