Description

Technical Field

[0001] This invention relates to the field of medical assistive devices, and more particularly to an electric nursing bed with rotation and lifting functions. Background Technology

[0002] Rotating nursing beds can switch between lying, sitting, and getting out of bed positions, which is especially convenient for patients who have difficulty getting up and down, and can greatly reduce the workload of nursing staff.

[0003] For example, patent document CN116687684A discloses a rotating gastroenterology patient care bed, including a bed frame assembly and a bed board assembly rotatably mounted on the bed frame assembly; the bed board assembly includes a back support plate, a hip support plate, a thigh support plate, and a calf support plate that are hinged together in sequence, and a linear drive unit is provided between the hip support plate and the back support plate, and between the hip support plate and the thigh support plate; a rotary drive unit is installed on the bed frame assembly, and the hip support plate is fixedly installed on the output end of the rotary drive unit to realize angle adjustment.

[0004] This nursing bed allows for reclining, sitting, and rotation for easy ambulation. However, it also has some drawbacks: 1. It lacks an assistive lifting function, merely rotating the user towards the ambulation position. This can be difficult for users with weak leg muscles, and also requires assistance from caregivers or other personnel. 2. It lacks an anti-slip function. Towards the end of the rotation, the user's body can slide downwards due to gravity and inertia. Users often rely on their hands to hold on, causing inconvenience and posing a safety hazard. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides an electric nursing bed with rotation and assisted lifting functions, which can significantly improve the convenience and safety of users getting out of bed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An electric nursing bed with rotation and assisted lifting functions is characterized by comprising a bed frame assembly, a mounting frame, a rotation drive unit, a rotating rod, a mattress frame, an anti-slip frame, a first linear push rod, and a second linear push rod. The mattress frame includes a back support, a hip support, a thigh support, and a calf support that are hinged together in sequence. The head of the anti-slip frame is rotatably connected to the head of the thigh frame, and the tail can rotate up and down. The mounting frame is mounted on the bed frame assembly via a rotary drive unit to support the mattress frame. The head of the rotating rod is fixed to the tail of the hip frame, and the tail of the rotating rod extends to the bottom of the thigh frame and is hinged to the mounting frame. The hip frame has a limiting frame at the head and a connecting seat passing through the limiting frame at the tail of the back frame. The first linear push rod is located between the mounting frame and the connecting seat and has a first extension and a second extension. When the first linear push rod extends to the first extension, the connecting seat swings in the limiting frame and drives the back frame to rotate upward relative to the hip frame. When the first linear push rod extends to the second extension, the connecting seat lifts upward against the limiting frame and drives the hip frame and thigh frame to tilt forward. A pivot structure is provided at the head of the mounting frame. A swing arm and a top wheel are connected to the pivot structure. The end of the swing arm away from the pivot structure extends towards the foot of the bed and slides in the groove of the lower leg frame. The second linear push rod is located between the mounting frame and the pivot structure. As the second linear push rod retracts, it drives the pivot structure to rotate, causing the swing arm to swing downward, driving the tail of the lower leg frame to rotate downward, and at the same time driving the top wheel to rotate upward, lifting the tail of the anti-slip frame upward.

[0007] Preferably, the bed frame assembly includes a bed beam, a headboard assembly and a footboard assembly disposed at both ends of the bed beam.

[0008] Preferably, the rotary drive unit includes a fixed sleeve, a rotating sleeve, a rotating disk, and a third linear push rod; The fixing sleeve is fixed to the bed frame assembly in a vertical position; The rotating sleeve is fitted into the fixed sleeve. The top of the rotating sleeve is connected to the mounting frame, and the lower end is connected to a rotating disk. A drive frame is connected to the rotating disk. The base of the third linear push rod is hinged to the bed frame assembly, and the piston rod of the third linear push rod is hinged to the drive frame.

[0009] Preferably, the tail ends of the hip frame and back frame, and the head ends of the thigh frame are supported on the mounting frame, and the bed frame assembly has a support beam for supporting the head end of the back frame and the tail end of the leg frame.

[0010] Preferably, the limiting frame is a U-shaped frame, with one side of the U-shaped opening of the limiting frame fixed to the head position of the hip frame. The connecting seat consists of two parallel plates, with the heads of the two plates fixed to the tail of the back frame. The tail ends of the plates pass through the limiting frame and are hinged to the piston rod of the first linear push rod. The motor seat of the first linear push rod is hinged to the tail position of the mounting frame.

[0011] Preferably, the rotating shaft structure includes a first shaft and a second shaft arranged axially, with a hinge plate at one end of the first shaft and the second shaft facing each other, the piston rod of the second linear push rod being connected to the two hinge plates, and the motor seat of the second linear push rod being hinged to the head of the mounting frame.

[0012] Preferably, a roller is connected to the end of the swing arm away from the pivot structure, and a connecting plate is provided below the lower leg frame, with the slide groove formed on the connecting plate.

[0013] Preferably, armrests are provided on both sides of the hip support.

[0014] The advantages of this invention are: the rotary drive unit drives the mattress frame to rotate in a direction that makes it easier for the user to get out of bed; the second linear push rod drives the lower leg frame to swing downward and retract to below the thigh and hip frames; at the same time, the top wheel pushes against the tail of the anti-slip frame and rotates upward, which can support the user's legs and play an anti-slip role; the first linear push rod drives the hip frame and lower leg frame to tilt forward, making it easier for the user to get out of bed.

[0016] Combination Figures 1 to 6 The electric nursing bed with rotation and lifting functions of the present invention will be further described.

[0017] An electric nursing bed with rotation and assisted lifting functions is characterized by comprising a bed frame assembly 1, a mounting frame 10, a rotation drive unit 8, a rotating rod 5, a mattress frame 2, an anti-slip frame 3, a first linear push rod 6, and a second linear push rod 7.

[0018] The mattress frame 2 includes a backrest frame 21, a hip frame 22, a thigh frame 23, and a calf frame 24, which are sequentially hinged together by a U-shaped plate. The head of the anti-slip frame 3 is rotatably connected to the head position of the thigh frame 23, and the tail of the anti-slip frame 3 can swing up and down. The head and tail refer to the sides corresponding to the head and foot of the nursing bed, respectively. The mounting frame 10 is mounted on the bed frame assembly 1 via a rotary drive unit 8 to support the mattress frame 2. There are two rotating rods 5. The heads of the two rotating rods 5 are fixed to the tail of the hip frame 22, and the tails of the two rotating rods 5 extend to the bottom of the thigh frame 23 and are then hinged to the left and right side walls of the mounting frame 10 by pins.

[0019] A limiting frame 221 is provided at the head of the hip frame 22, corresponding to the head of the bed. A connecting seat 211 passing through the limiting frame 221 is provided at the tail of the back frame 21, corresponding to the foot of the bed. The first linear push rod 6 is located between the mounting frame 10 and the connecting seat 211, and has a first extension and a second extension. When the first linear push rod 6 extends to the first extension, the connecting seat 211 swings in the limiting frame 221 and drives the back frame 21 to rotate upward relative to the hip frame 22. When the first linear push rod 6 extends to the second extension, the connecting seat 211 lifts upward against the limiting frame 221, causing the hip frame 22 and thigh frame 23 to tilt forward, making it easier for the user to get out of bed.

[0020] A pivot structure 9 is provided at the tail of the mounting frame 10. A swing arm 93 and a top wheel 94 are connected to the pivot structure 9. The end of the swing arm 93 away from the pivot structure 9 extends towards the foot of the bed and slides in the groove 242 of the leg support 24. The second linear push rod 7 is located between the mounting frame 10 and the pivot structure 9. As the second linear push rod 7 retracts, it drives the pivot structure 9 to rotate, causing the swing arm 93 to swing downward and drive the tail of the leg support 24 to rotate downward, allowing the user's lower legs to be lowered. At the same time, it drives the top wheel 94 to rotate upward, lifting the tail of the anti-slip frame 3 to provide anti-slip support for the user's legs.

[0021] The bed frame assembly 1 includes a front and rear extending bed beam 11, a headboard assembly 12 and a footboard assembly 13 located at both ends of the bed beam 11, which serve as the overall support.

[0022] The rotary drive unit 8 includes a fixed sleeve 82, a rotating sleeve, and a third linear push rod 81.

[0023] The fixed sleeve 82 is vertically fixed to the middle position of the bed beam 11 by bolts. The rotating sleeve is fitted in the fixed sleeve 82 by two bearings, the lower bearing being a plane bearing. A fixed plate 85 is connected to the top of the rotating sleeve, which is welded to the mounting frame 10 or fixed by bolts. The lower end of the rotating sleeve is connected to a rotating disk 83 by bolts. The rotating disk 83 is located on the lower outer side of the fixed sleeve 82, and a drive frame 84 is connected to the edge of the rotating disk 83. The tail of the motor seat of the third linear push rod 81 is hinged to the lower surface of the bed beam 11 by a U-shaped hinge seat, and the piston rod of the third linear push rod 81 is hinged to the drive frame 84. By extending and retracting the third linear push rod 81, the rotating sleeve and the mattress frame 2 can be driven to rotate back and forth by 90°.

[0024] The drive frame 84 includes a sleeve fixed vertically on the rotating disk 83 and two hinged plates fitted on the sleeve. The piston rod of the third linear push rod 81 is hinged between the two hinged plates.

[0025] In this embodiment, the rotary drive unit 8 can also be a rotary drive structure in the prior art, such as a rotary table that can be purchased directly.

[0026] When the electric bed is in a flat position, the tail of the hip frame 22, the back frame 21, and the head of the thigh frame 23 are supported on the mounting frame 10. The bed beam 11 of the bed frame assembly 1 has a support beam 14 for supporting the head of the back frame 21 and the tail of the leg frame 24, so that the back frame 21, hip frame 22, thigh frame 23 and leg frame 24 are stably supported as a whole.

[0027] The limiting frame 221 is a U-shaped frame. One side of the U-shaped opening of the limiting frame 221 is fixed to the head side of the hip frame 22 by welding, and the closed side extends towards the head of the bed. The connecting seat 211 consists of two parallel plates. The heads of the two plates are welded to the tail side of the back frame 21. The tail ends of the two plates pass through the limiting frame 221 and are hinged to the piston rod of the first linear push rod 6. The motor seat of the first linear push rod 6 is hinged to the tail of the mounting frame 10. Within a certain extension range of the first linear push rod 6, the rotation of the plate will not interfere with the limiting frame 221. When the extension of the first linear push rod 6 exceeds a certain extension range, the plate abuts against the closed end 2211 of the limiting frame 221, which can drive the limiting frame 221 and the hip frame to move synchronously.

[0028] The rotating shaft structure 9 includes a first shaft 91 and a second shaft 92 arranged axially. The ends of the first shaft 91 and the second shaft 92 opposite to each other are connected to the left and right sides of the mounting frame 10 by pins. The ends of the first shaft 91 and the second shaft 92 facing each other have hinge plates 96. The piston rod of the second linear push rod is connected between the two hinge plates by pins. The motor seat of the second linear push rod 7 is hinged to the head of the mounting frame 10. Under this structure, when the second linear push rod 7 drives the rotating shaft structure 9 to rotate, the piston rod will not interfere with the first shaft 91 and the second shaft 92.

[0029] Two swing arms 93 are fixed to the first shaft 91 and the second shaft 92, respectively. The end of the swing arm 93 away from the rotating shaft structure 9 extends towards the lower leg bracket 24 and is connected to a roller. Two connecting plates 241 are provided below the lower leg bracket 24, and a sliding groove 242 is formed on the connecting plates for the roller to engage. When the second linear push rod 7 retracts, it drives the swing arm 93 to swing downward, and at the same time, it causes the roller to slide adaptively in the sliding groove 242, causing the tail of the lower leg bracket 24 to rotate downward.

[0030] A top plate 97 is fixed to both the first shaft 91 and the second shaft 92, and a top wheel 94 is fixed to the top plate 97. The angle between the top plate and the swing arm 93 is approximately 90°. When the second linear push rod 7 drives the lower leg frame 24 to swing down 90°, the top wheel 94 begins to contact the front and rear extending rods 31 on the anti-slip frame 3. As the second linear push rod 7 continues to retract, the lower leg frame 24 will continue to retract, and at the same time, the top wheel 94 will gradually lift the tail of the anti-slip frame 3, making the anti-slip frame 3 higher than the upper surface of the thigh frame 23. It should be noted that when the top wheel 94 is not in contact with the anti-slip frame 3, the anti-slip frame 3 is supported on the support rod 232 in the thigh frame 23, and the upper surface of the anti-slip frame 3 is flush with the frame surface of the thigh frame 23.

[0031] Handrails 4 are installed on both sides of the hip support 22 for easy support by the user.

[0032] When in use, when the nursing bed is in a lying position, the first linear push rod 6 is in a retracted state, the second linear push rod 7 is in an extended state, the back frame 21, hip frame 22, thigh frame 23 and calf frame 24 are all in a flat state and are supported and positioned by the mounting frame and support beam, and the third linear push rod 81 is in a retracted state, so that the mattress frame 2 is in a forward and backward extended state, allowing the user to lie flat normally. When the user needs to be in a seated position, the first linear actuator 6 extends to a certain extent. Figure 4 As shown, the connecting seat 211 rotates within the limiting frame 221, and the connecting seat 211 synchronously drives the tail side of the back frame 21 to rotate, so that the head side of the back frame 21 is raised upward for the user to lean against. When the user needs to get out of bed, the third linear push rod 81 extends, driving the rotating sleeve to rotate via the drive frame 84 and the rotating disk 83, causing the mattress frame 2 in the sitting position to gradually rotate 90°. Then, the second linear push rod 7 retracts, driving the rotating shaft structure 9 to rotate, causing the tail of the swing arm 93 to swing downward, thereby causing the tail of the leg support 24 to gradually retract downward. At the same time, the top wheel 94 on the rotating shaft structure 9 gradually rotates upward, pushing against the tail of the anti-slip frame 3 to gradually lift, supporting the user's legs and providing an anti-slip effect. Next, the first linear push rod 6 extends a second time after the first extension, causing the connecting seat 211 to push against the closed end 2211 of the limiting frame 221, and simultaneously lifting the hip support 22 and the rotating rod 5. The rotating rod 5 will also lift the thigh support 23 simultaneously, thus allowing the thigh support 23 and the hip support 22 to form a forward-leaning state, making it easier for the user to get out of bed. When the thigh support 23 and the hip support 22 are in a forward-leaning state, the anti-slip frame 3 can effectively prevent slipping due to the raised tail end.
