Description

Technical Field

[0001] The utility model relates to the technical field of nursing devices, in particular to a bed-turning auxiliary device for elderly people. Background Art

[0002] Elderly people are unable to move due to illness or trauma, which leads to long-term bed rest. Due to long-term bed rest, ventilation of the bed is inconvenient. If bedridden patients are not cared for regularly, they are very likely to develop bedsores, which brings great pain. At present, elderly people who are bedridden for a long time generally need long-term caregivers to turn the bedridden patients over and then provide care to avoid the occurrence of secondary diseases such as bedsores.

[0003] In order to help the elderly turn over in bed, caregivers need to frequently help the elderly turn over. Under the high frequency of turning over, the caregivers' labor intensity is also very high. In the prior art, there are also some devices to assist the elderly to turn over in bed. The structure of this auxiliary device is generally to set a flippable bed board on both sides of the patient to assist turning over. However, under this structure, the unilaterally flipped bed board is only on one side of the body, and the bed board needs to be driven to flip with a large amplitude to completely push the body to turn over to the side. Therefore, the turning assistance effect is not ideal, and the driving structure is not easy to design and the structure is relatively complicated.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a device to assist the elderly in turning over in bed. Utility Model Content

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] See also Figures 1 to 5 As shown;

[0040] This embodiment discloses a device for assisting elderly people in turning over in bed, comprising:

[0041] A bed board 1, two sets of support boards 2 are symmetrically arranged on both sides of the bottom of the bed board 1, and the two sets of support boards 2 are used as bed legs, and together with the bed board 1, form a conventional bed structure for use by the elderly in bed. The middle of the bed board 1 is hollowed out to form an assembly opening 3, so that the turning over assisting device can be assembled inside the assembly opening 3;

[0042] A primary pushing mechanism, which is arranged on the inner side of the assembly opening 3 on the bed board 1, is used to push one side of the body to make the body tilt. This tilt is to make the body tilt to one side, and it does not completely turn over to the side-lying state, but only prepares for the next action. The primary pushing mechanism includes two groups of flip plates 4 symmetrically arranged on the inner side of the assembly opening 3 and two groups of flip driving mechanisms symmetrically arranged under the bed board 1. The two groups of flip plates 4 respectively correspond to the two sides of the body, so that when one group of flip plates 4 is flipped, it pushes one side of the body to tilt the body. The flip driving mechanism is used to drive the flip plate 4 on the corresponding side to flip; and a secondary pushing mechanism, which is arranged on the flip plate 4 to push the tilted body to the side-lying state. The secondary pushing mechanism includes a pushing head structure that applies force on the body and a uniform speed driving mechanism for driving the pushing head structure to apply force to push the body. That is, after the body is tilted by the primary pushing mechanism, the secondary pushing mechanism continues to push the body to the side-lying position in a local position manner, and the uniform speed driving mechanism as the driving structure can drive the pushing head structure gently to the side-lying position at a uniform and gentle speed. The two pushing actions are performed separately to reduce the driving stroke of each turning action, and the uniform speed driving mechanism makes the pushing action uniform and gentle, so that the entire pushing action of assisted turning is relatively gentle, which meets the care needs of the elderly and makes the assisted turning effect better.

[0043] Preferably, a central support shaft 5 is arranged inside the assembly port 3 of the present embodiment, and the central support shaft 5 is arranged horizontally along the central axis of the bed board 1. Two groups of flip plates 4 are symmetrically arranged on both sides of the central support shaft 5. The flip plates 4 are rotatably connected to the central support shaft 5 through bearings, and the flip plates 4 on both sides are supported by the central support shaft 5 for flipping.

[0044] Secondly, this embodiment further defines the structure of the flip driving mechanism, specifically: the flip driving mechanism includes:

[0045] and a telescopic cylinder 7, one end of which is rotatably disposed on the inclined plate 6 and the other end of which is rotatably disposed on the flip plate 4 opposite to one end of the central support shaft 5.

[0046] The device of this embodiment, under the push of the telescopic cylinder 7, causes the flip plate 4 to flip over, so as to push one side of the body to a tilted state.

[0047] In addition, secondary pushing mechanisms are provided on the turning plate 4 of the present embodiment corresponding to the back and buttocks of the human body, so that force can be applied to the two main supporting positions on one side of the back of the body, thereby achieving the effect of local force application to push the body to turn over.

[0048] Preferably, the push head structure of this embodiment includes:

[0049] A bottom plate 8, a column 9 is arranged on the upper surface of the bottom plate 8;

[0050] The arc-shaped plate 10, the center position of the lower surface of the arc-shaped plate 10 is connected to the upper end of the column 9; and

[0051] The elastic wrapping layer 11 is coated on the upper surface of the arc plate 10 to contact the body to avoid damaging the body, wherein the elastic wrapping layer 11 is a soft cotton layer, or an elastic rubber layer or a silicone layer to gently contact the body.

[0052] Preferably, the center position of the lower surface of the arc plate 10 of this embodiment is rotatably connected to the upper end of the column 9, so that when the column 9 on the base plate 8 and the arc plate 10 support the body during flipping, the body angle changes. At this time, the arc plate 10 can flip with the body, and the force state on the body parts can be maintained at all times to better promote the body flipping.

[0053] The flip plate 4 is provided with an escape opening 12 for the bottom plate 8 and the arc plate 10 to extend out, so that the arc plate 10 can extend out to push the body to turn over.

[0054] Preferably, the uniform speed driving mechanism of this embodiment includes:

[0055] A cylindrical assembly housing 13, which is disposed on the lower surface of the flip plate 4 and communicates with the avoidance opening 12;

[0056] A lead screw 14 is axially rotatably disposed inside the cylindrical assembly housing 13 via a bearing;

[0057] A nut pair 15, which is coaxially arranged on the lead screw 14 and threadably engaged with the lead screw 14;

[0058] Push rods 16, which are multiple groups connected between the nut pair 15 and the base plate 8; and

[0059] The driving motor 17 is arranged at the bottom of the cylindrical assembly housing 13 to drive the lead screw 14 to rotate axially.

[0060] Specifically, the lead screw 14 is driven by the driving motor 17 to rotate, and is threadedly matched with the nut pair 15, and multiple sets of push rods 16 are arranged between the nut pair 15 and the base plate 8 so that the lead screw 14 cannot rotate relative to the lead screw 14. Therefore, the lead screw 14 moves axially along the lead screw 14, and then drives the base plate 8 to move through the push rod 16, and then drives the arc plate 10 to extend out of the avoidance opening 12 to push the elderly person to turn over.

[0061] Among them, the electrical connection and use control of electrical components such as the telescopic cylinder 7 and the drive motor 17 involved in this device are common knowledge known to technical personnel in this field and will not be repeated here.

[0062] To summarize, the device divides the assisted turning action into two steps through the primary pushing mechanism and the secondary pushing mechanism respectively. After the primary pushing mechanism tilts the body, the secondary pushing mechanism directly pushes the body to the side-lying state in different ways. The turning angle and action of this device are small, and the driving stroke is small, so that the turning pushing action is relatively gentle and precise, making the assisted turning action more reasonable and precise, and better replacing manual assistance for elderly people to turn over in bed.

[0063] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
