Description

Technical Field

[0001] This utility model relates to the field of nursing bed technology, specifically to a nursing bed with a turning and shifting function. Background Technology

[0002] A disabled person is someone who has lost the ability to care for themselves. According to internationally accepted standards, this is defined as an inability to perform one or two of the following six tasks: eating, dressing, getting in and out of bed, using the toilet, walking indoors, and bathing. Those unable to perform these tasks are defined as "mildly disabled," those unable to perform three or four are "moderately disabled," and those unable to perform five or six are "severely disabled." Caring for a disabled person is a physically demanding task. For example, moving the disabled person to change bed linens or turning them over requires considerable physical strength and endurance from the caregiver. It is difficult for a single caregiver to complete these tasks; usually, multiple caregivers are needed. Furthermore, the experience for the disabled person is often unpleasant.

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] As attached Figure 1 To be continued Figure 3 ,

[0019] Example 1:

[0020] A nursing bed with a turning and shifting function includes a bed body 1 and two movable frames 2. The two movable frames 2 are symmetrically arranged at the head and tail ends of the bed body 1. The two movable frames 2 are connected to a linear drive mechanism, which can drive the two movable frames 2 to move synchronously in a straight line along the width of the bed. Each of the two movable frames 2 has two vertical sliding grooves 3 on the side closest to each other. A horizontal lifting rod 5 is slidably connected between the two symmetrical sliding grooves 3 of the two movable frames 2 through a slider 4. The top of each end of the lifting rod 5 is provided with a traction rope 6. The traction rope 6 is guided by a pulley group and then connected to the movable end of a lifting cylinder 7. The lifting cylinder 7 is fixed on the front and rear sides of the movable frame 2. The lifting rod 5 is provided with three sliding rings 8. Each sliding ring 8 is connected to a spring buckle 10 through a fixing rope 9. The bed also includes a neck restraint strap 11, a waist restraint strap 12 and a knee restraint strap 13. Both sides of the neck restraint strap 11, waist restraint strap 12 and knee restraint strap 13 are provided with locking holes 14 for connecting elastic buckles.

[0021] The nursing bed in this embodiment has the functions of turning over and moving. When it is necessary to move the patient and change the bedding, the symmetrical center line of the two lifting rods 5 is first moved to coincide with the symmetrical center line of the patient's body when lying flat through the linear drive mechanism. First, the neck restraint strap 11, waist restraint strap 12 and knee restraint strap 13 are tied to the patient's neck, waist and knee respectively to ensure that these joints of the patient will not sag naturally during the lifting process. The spring buckles 10 on both sides are fastened into the buckle holes 14 of the straps closest to them. The two lifting cylinders 7 work at the same time, and the lifting rods 5 are pulled upward through the pulley group guide. The lifting rods 5 lift the patient to a certain height. After the bedding is changed, the patient is put down. When it is necessary to turn the patient over, only the spring buckle 10 on one side of the lifting rod 5 is used. The spring buckle 10 is fastened into the buckle hole 14 on the side of the corresponding strap that is far away from it. During the lifting process, the lifting rod 5 will pull up one side of the patient's body through the unilateral inclined fixing rope 9, thereby realizing the turning of the patient.

[0022] Example 2:

[0023] The linear drive mechanism includes a crossbar 15 connecting two movable frames 2. The crossbar 15 is located below the bed body 1 and passes through the support frames 19 on both sides of the bed body 1. A guide block 16 is fixed on the crossbar 15, and the guide block 16 is slidably connected to a guide groove 17. The guide groove 17 is fixed on a support plate 18, and the two ends of the support plate 18 are fixedly connected to the two support frames 19. A drive block 20 is also provided on the crossbar 15. The drive block 20 is threadedly connected to a drive screw 21, which is rotatably connected to the support plate 18 and connected to a drive motor. The drive block 20 is driven to move horizontally through the screw transmission structure, and the movable frames 2 on both sides are driven to move synchronously through the connected crossbar 15. When the movable frames 2 move, their position relative to the patient can be adjusted. When lifting the patient or turning the patient over, the movable frames 2 need to be at a certain distance from the patient, so as to control the angle of the fixing rope 9 when lifting or turning over.

[0024] Example 3:

[0025] The movable frame 2 has at least two rectangular mounting holes on both sides along the width of the bed frame 1. The back of the sliding groove 3 is fixed to any length position of the mounting holes by bolts. The rectangular mounting holes ensure that the distance between the two sliding grooves 3 can be adjusted within a certain range after they are fixed to accommodate patients of different body types.

[0026] Example 4:

[0027] The pulley block includes a first fixed pulley 22 and a second fixed pulley 23. The first fixed pulley 22 is located inside the movable frame 2, and the second fixed pulley 23 is located outside the movable frame 2. The traction rope 6 is guided by the first fixed pulley 22 and the second fixed pulley 23 and then connected to the lifting cylinder 7.

[0028] Example 5:

[0029] The length of the fixing rope 9 is adjustable. Specifically, it can be adjusted using a U-shaped clip. Bend one end of the fixing rope 9 into a U-shape and then secure it with the U-shaped clip to adjust the length of the fixing rope 9.
