Description

Technical Field

[0001] This utility model relates to the field of nursing technology, specifically to an adjustable nursing turning aid. Background Technology

[0002] Long-term bedridden patients (such as postoperative patients, the elderly, paralyzed patients, etc.) need to be turned regularly (usually every 2 hours) to prevent pressure sores, promote blood circulation and improve respiratory function. According to clinical data, if patients who have been bedridden for more than 24 hours are not turned in time, the incidence of pressure sores can be as high as 60%.

[0003] Existing devices have separate turning and backrest adjustment functions, requiring different devices to be used, which is cumbersome and takes up space. Therefore, we propose an adjustable nursing turning aid. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable nursing turning aid.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable nursing turning aid, including a support frame, wherein the support frame is internally provided with a turning component and an adjustment component;

[0006] The turning assembly includes a first threaded sleeve, a first slider, a rotating block, a support rod, a turning frame, a connecting frame, and a limiting rotating shaft. The side of the turning frame is rotatably connected to the inner wall of the support frame, the side of the rotating block is rotatably connected to the upper end face of the first slider, one end of the support rod is rotatably connected to the side of the rotating block, the other end of the support rod is slidably connected to the inner wall of the connecting frame, and the surface of the limiting rotating shaft is slidably connected to the inner wall of the first threaded sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0015] 1. This utility model converts rotational motion into linear motion through a threaded transmission mechanism, driving the turning frame to turn the patient over without the need for nursing staff to manually move the patient. It is especially suitable for patients with heavy weight or limb movement impairment. By controlling the direction of the first threaded sleeve, the left or right turning frame can be driven to turn over, realizing bidirectional switching between supine and left or right lateral positions.

[0016] 2. The turning component of this utility model uses the sliding linkage between the support rod and the connecting frame to make the turning frame tilt slowly, avoiding the sudden pulling during traditional manual turning, reducing discomfort such as dizziness and muscle strain caused by changes in body position. The rolling contact between the roller and the triangular block in the adjustment component realizes stepless smooth adjustment of the backrest angle. The patient can control the adjustment speed independently, avoiding the loss of security caused by the sudden tilting of the backrest.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 -Appendix Figure 4 The present invention is an adjustable nursing turning aid, including a support frame 1, and a turning component 2 and an adjustment component 3 are provided inside the support frame 1;

[0026] In Embodiment 1, the turning assembly 2 includes a first threaded sleeve 21, a first slider 23, a rotating block 24, a support rod 25, a turning frame 26, a connecting frame 27, and a limiting rotating shaft 28. The side of the turning frame 26 is rotatably connected to the inner wall of the support frame 1. The side of the rotating block 24 is rotatably connected to the upper end face of the first slider 23. One end of the support rod 25 is rotatably connected to the side of the rotating block 24, and the other end of the support rod 25 is slidably connected to the inner wall of the connecting frame 27. The surface of the limiting rotating shaft 28 is slidably connected to the inner wall of the first threaded sleeve 21. A first limiting rod 22 is connected to the inner wall of the support frame 1. The inner wall of the first slider 23 is slidably connected to the surface of the first limiting rod 22. The first threaded sleeve 21 is rotatably connected to the inner wall of the support frame 1. The inner wall of the first slider 23 is threadedly connected to the surface of the first threaded sleeve 21. The side of the connecting frame 27 is rotatably connected to the inner wall of the turning frame 26.

[0027] Specifically, by manually driving the first threaded sleeve 21 to rotate clockwise, the first slider 23 engages with the thread on the sleeve surface, and the slider slides to the right along the first limit rod 22. The rightward movement of the first slider 23 pushes the rotating block 24 to swing upward around the pin axis, causing the support rod 25 to tilt. The end of the support rod 25 slides downward in the groove of the connecting frame 27, while pushing the connecting frame 27 to rotate around its hinge axis with the flipping frame 26. The rotation of the connecting frame 27 is transmitted to the flipping frame 26 through the rotating shaft, causing it to slowly flip around the connecting axis with the support frame 1. When the first threaded sleeve 21 is rotated counterclockwise, the first slider 23 moves to the left, and the above-mentioned components move in the opposite direction, and the flipping frame 26 returns to the supine position.

[0028] In embodiment 2, the adjustment component 3 includes a backrest 31, a triangular block 32, a second threaded sleeve 34, a second slider 35, and a roller 36. The side of the triangular block 32 is connected to the lower end face of the backrest 31. The side of the limiting pivot 28 is slidably connected to the inner wall of the second threaded sleeve 34. The side of the roller 36 is rotatably connected to the upper end face of the second slider 35. The side of the roller 36 is rollingly connected to the side of the triangular block 32. The inner wall of the support frame 1 is connected to a second limiting rod 33. The inner wall of the second slider 35 is slidably connected to the surface of the second limiting rod 33. The second threaded sleeve 34 is rotatably connected to the inner wall of the support frame 1. The inner wall of the second slider 35 is threadedly connected to the surface of the second threaded sleeve 34. The side of the backrest 31 is rotatably connected to the inner wall of the flip frame 26.

[0029] Specifically, when the second threaded sleeve 34 is manually rotated clockwise, the second slider 35 slides along the surface of the second limit rod 33. The second slider 35 moves upward, causing the roller 36 to roll upward. When the roller 36 rolls on the inclined surface of the triangular block 32, it pushes the triangular block 32 to rotate around the hinge axis between the backrest 31 and the flip frame 26. The tilt angle of the triangular block 32 changes linearly with the displacement of the slider. The rotation of the triangular block 32 causes the backrest 31 to rotate synchronously, realizing stepless adjustment of the backrest 31 angle from 0° (lying flat) to 45° (half-sitting). During the adjustment process, the roller 36 always keeps in contact with the surface of the triangular block 32 to ensure smooth movement. When the second threaded sleeve 34 is rotated counterclockwise, the second slider 35 moves downward, and the roller 36 slides down along the inclined surface of the triangular block 32. The backrest 31 slowly returns to the lying position to avoid sudden tilting.

[0030] Working principle:

[0031] First, the first threaded sleeve 21 is driven to rotate by the limiting shaft 28. Due to the threaded transmission, the first slider 23 slides along the surface of the first limiting rod 22. The movement of the first slider 23 causes the rotating block 24 to swing, which in turn pushes the support rod 25 to tilt. The tilting motion of the support rod 25 is transmitted to the flipping frame 26 through the connecting frame 27, so that it flips around the rotation axis of the support frame 1, thereby turning the patient over. By controlling the direction of the first threaded sleeve 21, the two flipping frames 26 can be controlled to flip. When rotating forward, the left flipping frame 26 can be adjusted to flip, and when rotating backward, the right flipping frame 26 can be adjusted to flip. The limiting shaft 28 ensures the axial positioning of the first threaded sleeve 21 when it rotates, and prevents the slider from deviating.

[0032] The second threaded sleeve 34 is driven to rotate, and the second slider 35 slides back and forth along the second limit rod 33. When the slider moves, the roller 36 rolls on the side of the triangular block 32, pushing the triangular block 32 to tilt. The tilting of the triangular block 32 causes the backrest 31 to rotate around its rotation axis with the flip frame 26, thereby adjusting the angle of the backrest 31. The limit rotating shaft 28 is slidably connected to the inner wall of the second threaded sleeve 34 to ensure structural stability during the adjustment process. By engaging the limit rotating shaft 28 with the first threaded sleeve 21 and the second threaded sleeve 34 respectively, the angles of the backrest 31 and the flip frame 26 can be adjusted respectively. Thus, the entire workflow is completed.
