Description

Technical Field

[0001] This utility model relates to the field of turning pad technology, and in particular to an adjustable anti-pressure sore turning pad. Background Technology

[0002] The research focuses on the need for pressure ulcer prevention in long-term bedridden patients in the medical and nursing field. Pressure ulcers are caused by prolonged pressure on local tissues, leading to impaired blood circulation and damage to the skin and subcutaneous tissues. They are particularly prevalent among the elderly, paralyzed, and critically ill individuals with limited mobility. Traditional pressure ulcer prevention measures, such as regular manual turning and the use of static air mattresses, have significant limitations, prompting researchers to improve the functionality and applicability of products through structural innovation and material optimization.

[0003] For patients who are comatose, have fractures, or are paralyzed and need to stay in bed for a long time, the pressure on the skin due to prolonged pressure in the same position can lead to ischemia and hypoxia in the local pressure area, resulting in blisters, epidermal shedding, and skin necrosis, thus forming pressure sores. Therefore, it is necessary to turn the patient over regularly. Currently, the turning of patients is mainly done by using pillows on the bed for fixation. However, because the pillows are relatively soft, they can quickly cause misalignment after turning over, affecting the effectiveness of the turning.

[0004] Therefore, there is an urgent need to provide an adjustable pressure ulcer prevention turning mat to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adjustable pressure ulcer prevention turning pad.

[0006] To solve the above-mentioned technical problems, the present invention provides an adjustable pressure ulcer prevention turning pad, including a mounting frame, two reinforcing rods fixedly connected to the inner sides of the two mounting frames, and multiple fan-shaped air cushions installed on the upper ends of the two mounting frames. Multiple cushioning sponges are provided on the top of each of the multiple fan-shaped air cushions, and a breathable pad is fixedly connected between the upper ends of the multiple cushioning sponges. The mounting bracket and the cushioning sponges are fixedly connected to the fan-shaped air cushions with Velcro. An inflation assembly is installed between the plurality of the fan-shaped air cushions, and the inflation assembly is capable of inflating the plurality of fan-shaped air cushions.

[0007] The present invention is further configured such that each of the plurality of said fan-shaped air cushions, mounting brackets, cushioning sponges and breathable cushions forms a rectangle, all of the same size.

[0008] The above technical solution ensures precise alignment of the overall structure, avoids interlayer misalignment and local collapse caused by size differences, and can be evenly distributed to the fan-shaped air cushion and buffer sponge through the mounting frame, and finally dispersed on the patient contact surface.

[0009] The present invention is further configured such that: the inflation component includes ventilation holes opened on multiple fan-shaped air cushions, a first inflation tube is fixedly connected to each pair of ventilation holes opposite each other, a second inflation tube is fixedly connected to one side of each pair of ventilation holes, an air pump is installed between one side of each pair of second inflation tubes, a shut-off valve is provided on the outer surface of each pair of first inflation tubes, multiple mounting blocks are fixedly connected to the inner side of each pair of fan-shaped air cushions, a guide rod is fixedly connected between each pair of mounting blocks, and a rotating block is rotatably connected to the body of each pair of guide rods.

[0010] Using the above technical solution, the air pump is started, and the compressed gas generated by the air pump is delivered to the connected vent through the second inflation tube and enters the corresponding fan-shaped air cushion, causing the fan-shaped air cushion to begin to expand. The gas inside the expanded fan-shaped air cushion enters the first inflation tube through the opposite vent. The gas is then transported along the first inflation tube to the vents of other fan-shaped air cushions, causing more fan-shaped air cushions to inflate. If zoned control is required, the corresponding air path can be closed by a shut-off valve to restrict the gas flow to a specific fan-shaped air cushion. However, when turning over is required, only one side of the fan-shaped air cushion needs to be inflated, causing the corresponding fan-shaped air cushion to begin to expand until it reaches its maximum value. At this time, the patient's side will tilt, thereby assisting the patient in turning over.

[0011] The present invention is further configured such that: the two interfaces of the air pump are respectively fixedly connected to one end of the two second inflation tubes, and the air pump can deliver gas to the vent through the second inflation tubes.

[0012] With the above technical solution, the two second inflation tubes can correspond to the fan-shaped air cushions in different areas. When it is necessary to assist the patient in turning over, the air pump can be controlled to supply air to one of the second inflation tubes separately, so that only the corresponding fan-shaped air cushion on one side is inflated and expanded, while the other side remains uninflated or deflated. There is no need to adjust all the fan-shaped air cushions as a whole, making the operation more efficient and more targeted.

[0013] The present invention is further configured such that: the mounting block is fixedly disposed on the surface of the fan-shaped air cushion facing its inner side, and the mounting blocks are spaced apart on the inner side of the fan-shaped air cushion.

[0014] With the above technical solution, the fan-shaped air cushion will expand and deform when inflated. The spaced distribution of the mounting blocks can reduce the coverage area of ​​the fan-shaped air cushion surface, reserve sufficient deformation space for the expansion of the fan-shaped air cushion, avoid squeezing and binding the fan-shaped air cushion due to the dense arrangement of mounting blocks, ensure that it can expand smoothly to the preset shape, and ensure the normal realization of the inflation function.

[0015] The present invention is further configured such that the rotating block and the guide rod are in a rotating fit, and the rotating block can rotate along the axial direction of the guide rod.

[0016] Through the above technical solution, the rotating block's ability to rotate along the guide rod axis can flexibly adapt to this deformation. When the fan-shaped air cushion deforms and causes the relative angle between the mounting block and the guide rod, the rotating block can dissipate the torque or tension generated by the rigid connection through its own rotation, thus protecting the integrity of the overall structure.

[0017] The present invention is further configured such that: a plurality of first inflation tubes are distributed in parallel intervals between the fan-shaped air cushions, and the adjacent two first inflation tubes are connected to the fan-shaped air cushions through corresponding vent holes.

[0018] Through the above technical solution, the first inflation pipes distributed in parallel intervals can form a grid-like transmission path for gas between multiple fan-shaped air cushions. Starting from the initially inflated fan-shaped air cushion, as the gas is diverted to the fan-shaped air cushions on both sides and around through the parallel pipes, the pressure and speed of the gas received by each fan-shaped air cushion are more balanced.

[0019] The beneficial effects of this utility model are as follows: 1. This utility model features a fan-shaped air cushion. The arc design of the fan-shaped air cushion can conform to the physiological curve of the human body when lying on the side or supine. It has a larger contact area with the body and more even pressure distribution. Compared with traditional flat air cushions, the fan-shaped structure can avoid tissue ischemia and hypoxia caused by excessive pressure at a single point, and significantly reduce the probability of pressure sores. 2. By setting up an inflatable component, the arc-shaped edge of the fan-shaped air cushion will form a wrap-around support after inflation. The inflatable component can adjust the air pressure to ensure that the hardness of the air cushion is matched with the patient's weight. Patients with a larger weight can increase the inflation volume to increase the support strength, while patients with a thin body can reduce the inflation volume to avoid excessive pressure and prevent friction caused by the body sliding when turning over.

[0023] Please see Figure 1 - Figure 5 An adjustable pressure ulcer prevention turning pad includes a mounting frame 1. Two reinforcing rods 2 are fixedly connected to the inner sides of the two mounting frames 1. Multiple fan-shaped air cushions 3 are installed on the upper end of the two mounting frames 1. The multiple fan-shaped air cushions 3, the mounting frame 1, the cushioning sponge 4 and the breathable pad 5 each form a rectangle with the same size. This ensures that the overall structure is precisely aligned and avoids interlayer misalignment and local collapse caused by size differences. The pad can be evenly distributed to the fan-shaped air cushions 3 and the cushioning sponge 4 through the mounting frame 1, and finally dispersed on the patient's contact surface. Multiple cushioning sponges 4 are set on the top of the multiple fan-shaped air cushions 3. The upper ends of the multiple cushioning sponges 4 are fixedly connected to the breathable pads 5. The mounting frame 1 and the cushioning sponge 4 are fixedly connected to the fan-shaped air cushions 3 with Velcro 6. like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an inflation assembly 7 is installed between multiple fan-shaped air cushions 3. The inflation assembly 7 includes vent holes 701 formed on the multiple fan-shaped air cushions 3. A first inflation tube 702 is fixedly connected to each pair of vent holes 701 opposite to each other. A second inflation tube 703 is fixedly connected to one side of each pair of vent holes 701. An air pump 704 is installed between the two second inflation tubes 703. A shut-off valve 705 is provided on the outer surface of each pair of first inflation tubes 702. Multiple mounting blocks 706 are fixedly connected to the inner side of the multiple fan-shaped air cushions 3. A guide rod 707 is fixedly connected between each pair of mounting blocks 706. The rods of the multiple guide rods 707 are rotatably connected to a rotating... Block 708; The air pump 704 is activated. The compressed gas generated by the air pump 704 is delivered through the second inflation pipe 703 to the connected vent 701 and enters the corresponding fan-shaped air cushion 3, causing the fan-shaped air cushion 3 to begin inflating. The gas inside the inflated fan-shaped air cushion 3 enters the first inflation pipe 702 through the opposite vent 701. The gas is then transported along the first inflation pipe 702 to the vents 701 of other fan-shaped air cushions 3, causing more fan-shaped air cushions 3 to inflate. If zone control is required, the corresponding air path can be closed by the shut-off valve 705 to restrict the gas flow to a specific fan-shaped air cushion 3. However, when it is necessary to turn over, only one side of the fan-shaped air cushion 3 needs to be inflated. The corresponding fan-shaped air cushion 3 begins to inflate until it reaches its maximum value. At this point, one side of the patient will tilt, thus assisting the patient in turning over. The two ports of the air pump 704 are fixedly connected to one end of each of the two second inflation tubes 703. The air pump 704 can deliver gas to the ventilation hole 701 through the second inflation tubes 703. The two second inflation tubes 703 can correspond to different areas of the fan-shaped air cushion 3. When it is necessary to assist the patient in turning over, the air pump 704 can be controlled to supply air to one of the second inflation tubes 703 separately, so that only the corresponding side of the fan-shaped air cushion 3 is inflated, while the other side remains uninflated or deflated. There is no need to adjust all the fan-shaped air cushions 3 as a whole. More efficient and more targeted, the mounting block 706 is fixedly set on the surface of the fan-shaped air cushion 3 facing inward, and the mounting block 706 is distributed at intervals on the inner side of the fan-shaped air cushion 3; when the fan-shaped air cushion 3 is inflated, it will expand and deform. The interval distribution of the mounting block 706 can reduce the coverage area of ​​the surface of the fan-shaped air cushion 3, reserve sufficient deformation space for the expansion of the fan-shaped air cushion 3, and avoid squeezing or binding the fan-shaped air cushion 3 due to the dense arrangement of the mounting block 706, ensuring that it can smoothly expand to the preset shape and ensure the normal realization of the inflation function. The rotating block 708 and the guide rod 707 are rotatably engaged, and the rotating block 708 can rotate along the axial direction of the guide rod 707.The rotating block 708's ability to rotate along the axial direction of the guide rod 707 can flexibly adapt to this deformation. When the deformation of the fan-shaped air cushion 3 causes the relative angle between the mounting block 706 and the guide rod 707, the rotating block 708 can dissipate the torque or tension generated by the rigid connection through its own rotation, protecting the integrity of the overall structure. Multiple first inflation tubes 702 are distributed in parallel intervals between the fan-shaped air cushions 3, and adjacent first inflation tubes 702 are connected to the fan-shaped air cushion 3 through corresponding vent holes 701. The parallel interval distribution of the first inflation tubes 702 enables the gas to form a grid-like transmission path between the multiple fan-shaped air cushions 3. Starting from the initially inflated fan-shaped air cushion 3, as the gas is diverted to the fan-shaped air cushions 3 on both sides and around the perimeter through parallel pipes, the pressure and speed of the gas received by each fan-shaped air cushion 3 are more balanced. The inflation assembly 7 can inflate multiple fan-shaped air cushions 3.

[0024] When using this invention, the air pump 704 is activated. The compressed gas generated by the air pump 704 is delivered through the second inflation tube 703 to the vent 701 connected thereto, and enters the corresponding fan-shaped air cushion 3, causing the fan-shaped air cushion 3 to begin to expand. The gas inside the expanded fan-shaped air cushion 3 enters the first inflation tube 702 through the opposite vent 701. The gas is then transmitted along the first inflation tube 702 to the vents 701 of other fan-shaped air cushions 3, causing more fan-shaped air cushions 3 to inflate. If zoned control is required, the corresponding air path can be closed by the shut-off valve 705 to restrict the gas flow to a specific fan-shaped air cushion 3. However, when turning over is required, only one side of the fan-shaped air cushion 3 needs to be inflated, causing the corresponding fan-shaped air cushion 3 to begin to expand until it reaches its maximum value. At this time, the patient's side will tilt, thereby assisting the patient in turning over.
