Description

[Technical Field]

[0001] The present invention relates to the technical field of medical assistive devices, and in particular to an electric nursing bed with a rotating function and a standing-up assist function. [Background technology]

[0002] The rotating nursing bed can be switched between lying, sitting and out of bed positions, which is particularly convenient for patients who have difficulty getting up, lying down or getting out of bed, and can significantly reduce the workload of nursing staff.

[0003] For example, patent document publication number CN116687684A discloses a rotating gastroenterological patient-care bed, which includes a bed frame assembly and a bed board assembly rotatably attached to the bed frame assembly, and the bed board assembly includes a back support board, a buttocks support board, a thigh support board, and a lower leg support board that are hingedly connected in order, with linear drive units provided between the buttocks support board and the back support board, and between the buttocks support board and the thigh support board, and a rotary drive unit attached to the bed frame assembly, and the buttocks support board is fixedly attached to the output end of the rotary drive unit to achieve angle adjustment.

[0004] This nursing bed can be used in both lying and sitting positions, and after rotation, it makes it easy to get out of bed. However, this nursing bed has the following defects during use: 1. It does not have a function to assist standing up, so it only rotates users who have difficulty moving to the bed-getting direction. Users with weak thigh muscles will have difficulty getting out of bed, and it is also difficult for caregivers and others to help the user get up. 2. It does not have a non-slip function, so by the time the rotation is finished, the user's body will slide downward due to gravity and inertia, and the user often has to hold on tightly with both hands to prevent slipping off, which is inconvenient for the user and poses a safety risk.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The electric nursing bed with a rotation function and a standing-up assist function of the present invention will be further described with reference to FIGS.

[0018] The electric nursing bed has a rotation function and a standing-up assist function, and includes a bed frame assembly 1, a mounting frame 10, a rotation drive unit 8, a rotation rod 5, a mattress frame 2, an anti-slip frame 3, a first linear push rod 6, and a second linear push rod 7.

[0019] The mattress frame 2 includes a back frame 21, a hip frame 22, a thigh frame 23, and a lower leg frame 24, which are sequentially hinged via a U-shaped plate. The head portion of the anti-slip frame 3 is rotatably connected to the head portion of the thigh frame 23, and the rear portion of the anti-slip frame 3 can swing up and down. The head portion and rear portion refer to the head and foot portions of the nursing bed, respectively. The mounting frame 10 is attached to the bed frame assembly 1 via a rotation drive unit 8 to support the mattress frame 2. There are two rotation rods 5, the head portions of which are fixed to the rear portions of the hip frame 22 and the rear portions of which extend below the thigh frame 23 and are connected to the left and right side walls of the mounting frame 10 via pin shafts.

[0020] A position limiting frame 221 is provided at the head portion of the buttocks frame 22, i.e., the side corresponding to the head side of the bed, and a connecting sheet 211 that passes through the position limiting frame 221 is provided at the rear portion of the back frame 21, i.e., the side corresponding to the foot side of the bed. The first straight push rod 6 is disposed between the mounting frame 10 and the connecting sheet 211 and has a first extension portion and a second extension portion. When the first straight push rod 6 extends at the first extension portion, the connecting sheet 211 swings within the position limiting frame 221 and drives the back frame 21 to rotate upward relative to the buttocks frame 22. When the first straight push rod 6 extends at the second extension portion, the connecting sheet 211 is pressed against the position limiting frame 221 and lifted upward, tilting the buttocks frame 22 and thigh frame 23 forward and making it easier for the user to get out of bed.

[0021] A rotary shaft structure 9 is provided at the rear of the mounting frame 10, and a swing arm 93 and a top wheel 94 are connected to the rotary shaft structure 9. One end of the swing arm 93 away from the rotary shaft structure 9 extends toward the rear of the bed and slides into and fits within the slide groove 242 of the lower leg frame 24. The second linear push rod 7 is provided between the mounting frame 10 and the rotary shaft structure 9. When the second linear push rod 7 contracts, it rotates the rotary shaft structure 9, swinging the swing arm 93 downward and rotating the rear of the lower leg frame 24 downward, lowering the user's lower leg. At the same time, it rotates the top wheel 94 upward, lifting the rear of the anti-slip frame 3 upward and supporting the user's thigh to prevent slipping.

[0022] The structure of the bed frame assembly 1 includes a bed beam 11 extending from front to back, and a headboard assembly 12 and a footboard assembly 13 disposed at both ends of the bed beam 11, thereby serving to support the entire structure.

[0023] The structure of the rotary drive unit 8 includes a fixed sleeve 82 , a rotary sleeve and a third linear push rod 81 .

[0024] The fixed sleeve 82 is fixed vertically to the bed beam 11 at its midpoint with bolts. The rotating sleeve is fitted to the fixed sleeve 82 via upper and lower bearings, the lower bearing being a flat bearing. A fixed plate 85 is connected to the top of the rotating sleeve, which is fixed to the mounting frame 10 by welding or bolts. A rotating disk 83 is connected to the lower end of the rotating sleeve with bolts. The rotating disk 83 is located below and outside the fixed sleeve 82, and a drive frame 84 is connected to the edge of the rotating disk 83. The rear of the motor base of the third linear push rod 81 is hinged to the underside of the bed beam 11 via a U-shaped hinge seat, and the piston rod of the third linear push rod 81 is hinged to the drive frame 84. The extension and contraction of the third linear push rod 81 allows the rotating sleeve and mattress frame 2 to rotate 90 degrees back and forth.

[0025] The drive frame 84 includes a sleeve fixed vertically to the rotary disc 83 and two hinge plates fitted into the sleeve, and the piston rod of the third linear push rod 81 is hingedly connected between the two hinge plates.

[0026] In this embodiment, the rotary drive unit 8 may be a rotary drive structure in the prior art, such as a directly available rotary table.

[0027] When the electric bed is in a recumbent position, the buttocks frame 22, the rear of the back frame 21, and the head portion of the thigh frame 23 are supported by the mounting frame 10. The bed beam 11 of the bed frame assembly 1 is provided with a support beam 14 for supporting the head portion of the back frame 21 and the rear portion of the lower leg frame 24, thereby stably supporting the back frame 21, buttocks frame 22, thigh frame 23, and lower leg frame 24 as a whole.

[0028] The position limiting frame 221 is a U-shaped frame, with the open side of the U-shape of the position limiting frame 221 welded to the head side of the hip frame 22 and the closed side extending toward the head side of the bed. The connecting sheet 211 is made of two parallel plates, with the heads of the two plates welded to the rear of the back frame 21, the rear ends of the plates passing through the position limiting frame 221 to hinge-connect the piston rod of the first linear push rod 6, and the motor base of the first linear push rod 6 is hinge-connected to the rear of the mounting frame 10. Within the extension range of the first extension section of the first linear push rod 6, the rotation of the plate does not interfere with the position limiting frame 221. When the extension amount of the first linear push rod 6 exceeds the extension range of the first extension section, the plate abuts against the closed side 2211 of the position limiting frame 221, allowing the position limiting frame 221 and the hip frame to move synchronously.

[0029] The rotary shaft structure 9 includes a first shaft 91 and a second shaft 92 arranged in the axial direction, with opposite ends of the first shaft 91 and the second shaft 92 connected to the left and right sides of the mounting frame 10 via pin shafts, hinge plates 96 are provided at the opposing ends of the first shaft 91 and the second shaft 92, and the piston rod of the second linear push rod 7 is connected between the two hinge plates via a pin shaft, with the motor base of the second linear push rod 7 hingedly connected to the head portion of the mounting frame 10. With this structure, when the second linear push rod 7 rotates the rotary shaft structure 9, the piston rod does not interfere with the first shaft 91 and the second shaft 92.

[0030] There are two swing arms 93, each fixed to a first shaft body 91 and a second shaft body 92. One end of the swing arms 93 remote from the rotary shaft structure 9 extends toward the lower leg frame 24 and is connected to a roller, and two connecting plates 241 are provided on the underside of the lower leg frame 24, with slide grooves 242 in which the rollers interlock. When the second linear push rod 7 contracts, the swing arm 93 is swung downward and the rollers slide adaptively within the slide grooves 242, rotating the rear of the lower leg frame 24 downward.

[0031] A top plate 97 is fixed to each of the first shaft body 91 and the second shaft body 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 swings the lower leg frame 24 downward by 90°, the top wheel 94 begins to contact the rod body 31 extending forward and backward on the anti-slip frame 3. As the second linear push rod 7 continues to contract, the lower leg frame 24 continues to retract. At the same time, the top wheel 94 gradually lifts the rear of the anti-slip frame 3, causing the anti-slip frame 3 to rise higher than the upper surface of the thigh frame 23. When the top wheel 94 is not in contact with the anti-slip frame 3, the anti-slip frame 3 is supported by the support rod 232 inside 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.

[0032] Armrests 4 are attached to both sides of the hip frame 22 to facilitate support of the user.

[0033] When the nursing bed is in a recumbent position, the first linear push rod 6 is in a contracted position, the second linear push rod 7 is in an extended position, the back frame 21, the buttocks frame 22, the thigh frame 23 and the lower leg frame 24 are all in a flat position and are supported and positioned by the mounting frame and the support beam, and the third linear push rod 81 is in a contracted position, so that the mattress frame 2 is extended forward and backward, allowing the user to take a recumbent position.

[0034] When the user wants to sit down, as shown in FIG. 4, the first straight push rod 6 is extended at the first extension portion, causing the connecting seat 211 to rotate within the position limiting frame 221, and the connecting seat 211 simultaneously drives the rear side of the back frame 21 to rotate, lifting the head side of the back frame 21 upward so that the user can lean against the backrest.

[0035] When the user wants to stand up from the bed, the third linear push rod 81 extends, and the drive frame 84 and the rotary disc 83 rotate the rotary sleeve, gradually rotating the mattress frame 2 in the sitting position by 90°. Then, the second linear push rod 7 retracts, and the rotary shaft structure 9 rotates, causing the rear of the swing arm 93 to swing downward, gradually pulling the rear of the lower leg frame 24 downward. At the same time, the top wheel 94 of the rotary shaft structure 9 gradually rotates upward, and the anti-slip frame 3 The rear part is gradually lifted to support the user's thighs and provide an anti-slip effect, and then, as the first extension part of the first linear push rod 6 extends, the second extension part also extends, causing the connecting sheet 211 to press against the closed side 2211 of the position limiting frame 221, synchronously lifting the buttocks frame 22 and the rotating rod 5, and at the same time, the rotating rod 5 lifts the thigh frame 23, causing the thigh frame 23 and buttocks frame 22 to lean forward, making it easier for the user to stand up from the bed. When the thigh frame 23 and buttocks frame 22 are leaning forward, the rear part of the anti-slip frame 3 rises, effectively preventing slipping.
