Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to a body positioning fixation device for the prevention of pressure injuries. Background Technology

[0002] Pressure injuries, also known as pressure ulcers or bedsores, are caused by prolonged pressure on local tissues, leading to impaired blood circulation, persistent ischemia, hypoxia, and malnutrition, which in turn results in soft tissue ulceration and necrosis. This condition is common among patients who are bedridden for extended periods, have limited mobility, or require maintaining a fixed position for long periods due to illness. Pressure injuries not only cause severe pain but also increase the risk of infection and prolong the recovery period.

[0003] In clinical nursing, many patients require prolonged bed rest due to their condition, resulting in continuous pressure on the areas of their body in contact with the bed, especially bony prominences such as the sacrum, coccyx, heels, and scapulae, making these areas prone to pressure injuries. To effectively prevent pressure injuries, reducing the pressure, shear force, and friction on local tissues is crucial. However, traditional nursing methods struggle to precisely control patient positioning, making it difficult to achieve even pressure distribution and effective relief.

[0004] Therefore, we have made improvements to this and proposed a body positioning device for the prevention of pressure injuries. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, this utility model provides a body positioning fixation device for the prevention of pressure injuries, so as to improve the above-mentioned problems.

[0006] The application is as follows:

[0007] Including bed frames;

[0008] The main shaft rotates symmetrically on both sides of the long side of the bed frame and extends to the outside of the bed frame;

[0009] A rotating plate is fixedly connected to the main shaft near the long side of the bed frame and extends symmetrically to both parallel sides with the main shaft as the center.

[0010] Sliding grooves are formed at both ends of the rotating plate;

[0011] A sliding block is slidably connected in the sliding groove, and the sliding direction is consistent with the long side direction of the rotating plate;

[0012] The first spring is fixedly connected between the sliding groove and the sliding block, and restricts the sliding block from moving in the direction of the main shaft;

[0013] The secondary shaft is rotatably connected between the two sliding blocks and is parallel to the main shaft;

[0014] The second spring is connected to the ends of the two adjacent main shafts that extend to the outside of the bed frame;

[0015] When the patient is positioned above the bed frame and in contact with the main shaft and the secondary shaft, the adjacent secondary shaft rotates around the body pressing part under the constraint of the second spring, forming a local depression.

[0016] Preferably, when a downward pressure is applied to the sub-shaft that is furthest apart, the adjacent sub-shafts are pushed upward around the main shaft as a rotation point.

[0017] Preferably, the stiffness coefficient of the second spring is within a first range, the stiffness coefficient of the first spring is within a second range, and the minimum value within the first range is greater than the maximum value within the second range.

[0018] Preferably, there is a gap between two adjacent secondary shafts.

[0019] Preferably, a protective box covering the second spring and the main shaft extending out of the exposed section of the bed frame is fixedly connected to the bed frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the scheme of this application:

[0022] To address the problem that many patients require prolonged bed rest due to their condition, resulting in continuous pressure on the areas where their bodies contact the bed surface, especially bony prominences such as the sacrum, coccyx, heels, and scapulae, which are prone to pressure injuries, this application utilizes the rotational characteristics of the main and secondary shafts of the support that rotate on the bed frame. This allows for localized depressions under the constraint of spring force, preventing pressure injuries caused by high-intensity pressure on specific areas of the body. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] For an example, please refer to... Figure 1 , Figure 2 and Figure 3 A posture fixation device for the prevention of pressure injuries, bed frame 1;

[0030] Main shaft 2 rotates symmetrically on both sides of the long side of bed frame 1 and extends to the outside of bed frame 1;

[0031] The rotating plate 3 is fixedly connected to the long side of the main shaft 2 near the bed frame 1, and extends symmetrically to both parallel sides with the main shaft 2 as the center.

[0032] Sliding grooves 31 are formed at both ends of the rotating plate 3;

[0033] The sliding block 4 is slidably connected in the sliding groove 31, and the sliding direction is consistent with the long side direction of the rotating plate 3;

[0034] The first spring 5 is fixedly connected between the sliding groove 31 and the sliding block 4, and restricts the sliding block 4 from moving in the direction of the main shaft 2;

[0035] The secondary shaft 6 is rotatably connected between two sliding blocks 4 and is parallel to the main shaft 2;

[0036] The second spring 7 is connected to the ends of two adjacent main shafts 2 extending to the outside of the bed frame 1;

[0037] When the patient is above the bed frame 1 and in contact with the main shaft 2 and the secondary shaft 6, the adjacent secondary shaft 6 rotates around the human body pressing part under the restriction of the second spring 7 to form a local depression;

[0038] When the patient's local pressure is concentrated in the buttocks or a certain area, the two adjacent secondary axes 6 are subjected to downward pressure, causing the secondary axes 6 to bend downward and rotate around the main axis 2 as the rotation point, while moving downward. At this time, the supporting force of the secondary axes 6 on the patient above is reduced, achieving an adaptive pressure effect.

[0039] At the same time, the increased spacing between the secondary shafts 6 creates a more comfortable fit for protrusions in the human body, such as the buttocks.

[0040] When downward pressure is applied to the farthest secondary shaft 6, the adjacent secondary shaft 6 is pushed upward around the main shaft 2 as the rotation point;

[0041] The longitudinal transmission and lateral compensation of pressure are achieved through the lever-type force transmission structure, which causes the secondary shaft 6 at the far end of the force application point to produce a reverse displacement, forming multi-point coordinated support under the patient. Under repeated pressing, the patient's pressure-bearing part can be effectively squeezed in different ways. At this time, the secondary shaft 6 forms a lateral displacement under the action of the first spring 5, which increases the range of massage and blood circulation, effectively disperses local pressure load, and enhances the overall pressure bearing capacity of the bed.

[0042] Furthermore, since the secondary shaft 6 needs to overcome lateral pressure, the rotating plate 3 can move along the direction of the sliding groove 31 when tilted, so that the pressure of the secondary shaft 6 is transferred to the user's back and legs, thus better completing the function of pressing and activating blood circulation.

[0043] The spring constant of the second spring 7 is within the first range, and the spring constant of the first spring 5 is within the second range, with the minimum value within the first range being greater than the maximum value within the second range.

[0044] The second spring 7 acts as a suppressor to prevent the rotating plate 3 from flipping over, and has a high rigidity and strength. Similar to the elastic thread structure of an arm strength device, it keeps the rotation amplitude of the rotating plate 3 stable.

[0045] There is a gap between two adjacent secondary shafts 6;

[0046] By setting the inter-axis clearance to form a discontinuous support structure, while ensuring the overall rigidity of the bed surface, each secondary shaft 6 is allowed to produce independent micro-deformation, which reduces frictional loss between adjacent components and provides compensation space for thermal expansion deformation, significantly improving the service life of the bed.

[0047] A protective box 8 is fixedly connected to the bed frame 1, covering the second spring 7 and the main shaft 2 extending out of the exposed section of the bed frame 1;

[0048] The fully enclosed protective structure physically isolates the core transmission components, preventing mechanical jamming caused by foreign object intrusion. It also avoids direct human contact with rotating parts, thus improving safety while ensuring the reliability of equipment operation.

[0049] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
