Description

Technical Field

[0001] This application relates to the field of medical care, and in particular to a nursing bed. Background Technology

[0002] Nursing beds are generally powered beds, which can be electric or manual. They are designed according to the patient's bedridden lifestyle and treatment needs. They are designed to allow family members to accompany the patient and have multiple nursing functions and operation buttons. They are insulated and safe beds. Patients who are bedridden for a long time are prone to poor blood circulation and need to be turned over by medical staff regularly. In order to facilitate the turning of patients, most nursing beds have a rotating bed board function.

[0003] Currently, the prone-head-lower-feet-high and supine-head-high-feet-lower positions of nursing beds are achieved by changing the height of the headboard or footboard. However, in this tilting position, the patient's body will bend, which is not suitable for patients with spinal fractures (cervical, thoracic, lumbar), pelvic fractures, and severe lower limb injuries, because it can easily cause secondary skeletal displacement and further injury. Utility Model Content

[0004] To reduce the injury to patients when turning over, this application provides a nursing bed.

[0005] The nursing bed provided in this application adopts the following technical solution: A nursing bed includes a bed board, a frame assembly, a first frame rotation assembly for driving the bed board to rotate in a first direction, and a second frame rotation assembly for driving the bed board to rotate in a second direction. The frame assembly includes a first frame, a second frame, and a third frame, which are connected sequentially from the inside to the outside. The second frame drives the first frame to rotate through the first frame rotation assembly, and the third frame drives the second frame to rotate through the second frame rotation assembly. The first direction and the second direction are different. The bed board is fixedly connected to the first frame.

[0006] By adopting the above technical solution, when it is necessary to adjust the patient's rotation in the first direction, the first rotating component drives the first frame to rotate in the first direction, and the first frame drives the bed board to rotate. When it is necessary to adjust the patient's rotation in the second direction, the second rotating component drives the frame to rotate in the second direction, and the second frame drives the bed board to rotate, thereby realizing multi-angle rotation of the patient. Since this structure directly drives the entire bed board to rotate, the patient remains in a straight position when being turned over, thereby reducing the bending of the patient's body and reducing the damage.

[0007] Optionally, the first rotating assembly includes a first push rod motor, the two ends of which are rotatably connected to the first frame and the second frame, respectively.

[0008] By adopting the above technical solution, the first frame is driven to rotate by the first push rod motor. Since the push rod motor has a large load capacity, it can fix the first frame when the push rod motor is not working.

[0009] Optionally, the upper end of the first frame is connected to a plurality of support rods, the upper ends of the plurality of support rods are all connected to the frame structure, and the bed board is fixedly connected to the upper end of the frame structure.

[0010] By adopting the above technical solution, the support rod is used to raise the height of the bed board, making the use of the nursing bed more convenient.

[0011] Optionally, the bed board includes a headboard, a footboard, and a support plate. The support plate is fixedly connected to the frame structure. The headboard and footboard are rotatably connected to both ends of the frame structure. The frame structure is equipped with a headboard motor for driving the headboard to rotate and a footboard motor for driving the footboard to rotate.

[0012] By adopting the above technical solution, both the headboard motor and the footboard motor are installed on the frame structure, so that the position of the headboard or footboard can still be changed individually when the bed board rotates as a whole.

[0013] Optionally, the second frame is covered by a third frame, with both ends of the second frame rotatably connected to the third frame along its length. The third frame is equipped with a second rotating component for driving the second frame to rotate.

[0014] By adopting the above technical solution, the second transmission component drives the second frame to rotate. Since both ends of the second frame in the length direction are rotatably connected to the third frame, the second frame changes the height of both ends in the width direction of the bed board when rotating, thereby enabling the patient to turn left to the left or right to the right, making the function more comprehensive.

[0015] Optionally, the second rotating assembly includes a first connecting rod, a second connecting rod, and a second push rod motor. The first connecting rod is disposed at the upper end of the third frame in a vertically upward direction, and the second connecting rod is disposed at the upper end of the second frame in a vertically upward direction. The upper end of the first connecting rod is connected to the upper end of the second connecting rod through the second push rod motor, and the two ends of the second push rod motor are rotatably connected to the first connecting rod and the second connecting rod, respectively.

[0016] By adopting the above technical solution, when the second push rod motor is working, the distance between the first connecting rod and the second connecting rod is changed by the movement of the push rod. Since the first connecting rod is fixed, the second connecting rod is displaced. When the second connecting rod moves, it drives the second frame to rotate. Since the push rod motor has a large load capacity, it can fix the second frame when the second push rod motor is not working.

[0017] Optionally, the first connecting rod and the second connecting rod are of equal length, and when the second frame is in a horizontal state, the first push rod motor is in a horizontal state.

[0018] By adopting the above technical solution, this structure makes it easy to observe whether the bed board is in a horizontal state.

[0019] Optionally, the third frame is equipped with a controller, which is electrically connected to the first push rod motor, the second push rod motor, the headstock motor, and the tailstock motor and is used to control the opening and closing of the first push rod motor, the second push rod motor, the headstock motor, and the tailstock motor.

[0020] By adopting the above technical solution, the working status of multiple motors can be controlled by the controller, and automatic turning can be set, reducing the workload of operators.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This structure directly drives the entire bed board to rotate, so that the patient remains in a straight position when being turned over, thereby reducing the bending of the patient's body and reducing the risk of injury.

[0023] Both the headboard motor and the footboard motor are mounted on the frame structure, allowing the headboard or footboard to be moved individually even when the bed board is rotated as a whole.

[0024] The second transmission component drives the second frame to rotate. Since both ends of the second frame are rotatably connected to the third frame in the length direction, the second frame changes the height of both ends in the width direction of the bed board when it rotates, thereby enabling the patient to turn left to the left or right to the right, making the function more versatile.

[0028] The following is in conjunction with the appendix Figure 1-2This application will be described in further detail.

[0029] This application discloses a nursing bed. (Refer to...) Figure 1 as well as Figure 2 A nursing bed includes a bed board 1, a frame assembly 2, a first frame rotation assembly 3 for rotating the bed board 1 in a first direction, and a second frame rotation assembly 4 for rotating the bed board 1 in a second direction. The first rotation direction is to rotate the patient to a prone position with the head lower than the feet or a supine position with the head higher than the feet. The second rotation direction is to rotate the patient to a left-turning position with the patient tilting to the left or a right-turning position with the patient tilting to the right. The first and second directions are perpendicular to each other. The frame assembly 2 includes a first frame 21, a second frame 22, and a third frame 23 that are sequentially rotated and sleeved together from the inside out. The second frame 22 drives the first frame 21 to rotate through the first frame rotation assembly 3, and the third frame 23 is rotated through the second frame. Component 4 drives the second frame 22 to rotate. Multiple support rods 5 are fixedly connected to the upper end of the first frame 21. The upper ends of the multiple support rods 5 are all fixedly connected to the frame structure 51. The bed board 1 is fixedly connected to the upper end of the frame structure 51. The bed board 1 includes a headboard 11, a footboard 12, and a support plate 13. The support plate 13 is fixedly connected to the frame structure 51. The headboard 11 and the footboard 12 are rotatably connected to both ends of the frame structure 51, respectively. The frame structure 51 is equipped with a headboard motor 14 for driving the headboard 11 to rotate and a footboard motor 15 for driving the footboard 12 to rotate. Through this structure, the headboard 11 or the footboard 12 can be rotated independently, thereby facilitating the adjustment of the patient's posture.

[0030] Reference Figure 1 as well as Figure 2 The first frame rotating assembly 3 includes a first push rod motor 31. The two ends of the first push rod motor 31 are rotatably connected to the first frame 21 and the second frame 22, respectively. When the first push rod motor 31 is working, since the second frame 22 is fixed, the first push rod motor 31 drives the first frame 21 to rotate, thereby driving the bed board 1 to rotate in the first direction.

[0031] Reference Figure 1 as well as Figure 2The second frame rotating assembly 4 includes a first connecting rod 41, a second connecting rod 42, and a second push rod motor 43. The first connecting rod 41 is fixed to the upper end of the third frame 23 in a vertically upward direction, and the second connecting rod 42 is fixed to the upper end of the second frame 22 in a vertically upward direction. The two ends of the second push rod motor 43 are rotatably connected to the upper ends of the first connecting rod 41 and the second connecting rod 42, respectively. The first connecting rod 41 and the second connecting rod 42 are of equal length. When the second frame 22 is in a horizontal state, the second push rod motor 43 is also in a horizontal state, which makes it easy to determine whether the bed board 1 is in a horizontal state. When the second push rod motor 43 is working, since the third frame 23 is fixed, the second push rod motor 43 drives the second frame 22 to rotate, thereby driving the bed board 1 to rotate in the second direction.

[0032] Reference Figure 1 as well as Figure 2 The third frame 23 is equipped with a controller 6. The controller 6 is electrically connected to the first push rod motor 31, the second push rod motor 43, the headstock motor 14, and the tailstock motor 15 and is used to control the opening and closing of the first push rod motor 31, the second push rod motor 43, the headstock motor 14, and the tailstock motor 15. By controlling the working status of multiple motors through the controller 6, automatic turning can be set to reduce the workload of the operator.

[0033] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
