Description

Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, specifically an adjustable pressure ulcer prevention stent. Background Technology

[0002] Pressure ulcers are skin or tissue injuries localized to a specific body surface. They occur due to prolonged pressure on the tissue, leading to insufficient blood supply, skin damage, ulceration, and even necrosis. They typically occur in people who are bedridden or sitting for extended periods. For patients with burns causing soft tissue damage, reconstructive surgery requires special attention to protecting the patient's skin.

[0003] Traditional pressure ulcer braces are mostly fixed-size parallel straight bars, which are difficult to adjust to the specific needs of patients. They also have limited support for soft sheets, which tend to sag and come into contact with the patient's skin. The friction between the patient's skin and the sheet can damage the already fragile skin surface and cause pressure ulcers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable pressure ulcer prevention support, which solves the problems of difficult size adjustment and poor support effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable pressure ulcer prevention support, including a support plate and a connecting plate. The connecting plate is provided in two sets and has an arched structure. The two connecting plates are arranged crosswise and the intersection point is rotatably connected by a pin. The two connecting plates form a cross frame. The four ends of the cross frame are installed on the support plate. One end of the connecting plate can slide on the support plate. The distance between the two support plates is adjusted by changing the cross angle between the connecting plates.

[0006] Furthermore, it also includes a ring, which is located in the area near the center of the arched structure. A sliding sleeve is provided on the area opposite to the ring on the connecting plate, and the sliding sleeve is fitted on the outer surface of the ring. When the connecting plate rotates, the sliding sleeve can slide along the ring to guide the rotation of the connecting plate.

[0007] Furthermore, it also includes supporting arc columns, which are distributed in the four directions of the ring and extend towards the pin shaft.

[0008] Furthermore, one end of the connecting plate is rotatably connected to the support plate, and a slider is fixed on the other end of the connecting plate near the support plate. A groove is provided on the upper surface of the support plate, and a sliding groove adapted to the slider is provided on the groove. A fixing block is fixed to the end of the slider away from the connecting plate after passing through the sliding groove.

[0009] Furthermore, a cam is rotatably connected to the connecting plate, and a slot adapted to the cam is provided inside the groove. Rotating the cam into the slot can self-lock the relative position of the connecting plate.

[0010] Furthermore, a connecting rope is fixed to the end of the supporting arc column away from the ring and the upper surface of the support plate, and a clip is fixed to one end of the connecting rope.

[0011] Furthermore, the tray has extensions at both ends, which are integral with the tray and are used to fit the edges of the bed sheet so that the bed sheet can hang down along the edges of the tray.

[0012] Furthermore, a support plate is fixed to the side of the tray away from the connecting plate, and an mounting plate is fixed to the end of the support plate away from the tray. The mounting plate has an L-shaped structure, which facilitates installation on the edge of the bed.

[0013] Furthermore, a cavity is formed between the support plate and the mounting plate, which allows for ventilation of the patient.

[0014] This utility model has the following beneficial effects:

[0015] 1. This adjustable pressure ulcer support has two relatively rotatable arched connecting plates. The relative rotation can adjust the distance between the two plates to modify the size of the support according to needs. Moreover, the arched cross frame formed by it can support the bed sheet to a higher position and the support distribution is more even compared with the general parallel straight bar frame, thus providing better support effect.

[0016] 2. This adjustable pressure ulcer prevention support, by setting a ring and a sliding sleeve, the ring has a supporting function, further reducing the gap between the connecting plates and cross frames, preventing the bed sheet from hanging down and contacting the patient's skin through the gap, causing pressure ulcers. At the same time, the sliding sleeve slides along the ring to guide the rotation of the connecting plates, making the distance adjustment process between the two support plates more stable.

[0017] 3. This adjustable pressure ulcer prevention support features supporting arc columns that provide support while reducing the gaps between the connecting plates and cross frames, preventing the bed sheet from sagging and contacting the patient's skin, thus avoiding pressure ulcers.

[0018] 4. This adjustable pressure ulcer prevention bracket, by setting a cam and a slot, can lock the relative position of the connecting plates by rotating the cam into the slot, thereby locking the distance between the two support plates and obtaining a stable bracket with appropriate size.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] The following is based on Figures 1-9 This invention describes an adjustable pressure ulcer prevention support provided in an embodiment of the present invention.

[0033] Please see Figures 1-5 This utility model provides a technical solution: an adjustable pressure ulcer prevention support, including a support plate 2, which has a supporting function, and a connecting plate 3. There are two sets of connecting plates 3, and the connecting plates 3 have an arched structure. The two connecting plates 3 are arranged crosswise, and the intersection is rotatably connected by a pin. The two connecting plates 3 form a cross frame, which has a supporting function. The arched structure of the connecting plate 3, compared with a general straight rod, can support the bed sheet to a higher position, which has a better supporting effect and prevents the bed sheet from drooping and contacting the patient's skin, causing pressure ulcers. The four ends of the cross frame are installed on the support plate 2, and one end of the connecting plate 3 can slide on the support plate 2. The distance between the two support plates 2 can be adjusted by changing the cross angle between the connecting plates 3.

[0034] Please see Figures 1-3 Furthermore, it also includes a ring 1, which is located in the area near the middle of the arched structure. The ring 1 also has a supporting function, further reducing the gap between the cross frames of the connecting plates 3, and preventing the bed sheet from hanging down and contacting the patient's skin through the gap, causing pressure sores. At the same time, a sliding sleeve 31 is provided on the area of ​​the connecting plate 3 opposite to the ring 1, and the sliding sleeve 31 is fitted on the outer surface of the ring 1. When the connecting plate 3 rotates, the sliding sleeve 31 can slide along the ring 1 to guide the rotation of the connecting plate 3, making the distance adjustment process between the two support plates 2 more stable. Moreover, the setting of the ring 1 will not affect the rotation of the connecting plate 3, and will not restrict the cross angle between the connecting plates 3.

[0035] Please see Figures 1-3 Furthermore, it also includes a supporting arc column 4, which can provide support and further reduce the gap between the cross frames of the connecting plates 3, preventing the bed sheet from hanging down and contacting the patient's skin through the gap, causing pressure sores. The supporting arc column 4 is distributed in the four directions of the ring 1 and extends towards the pin shaft.

[0036] Please see Figures 5-8 To achieve the adjustment of the cross angle between the connecting plates 3, one end of the connecting plate 3 is rotatably connected to the support plate 2, and the other end of the connecting plate 3 is fixed with a slider 32 near the support plate 2. The upper surface of the support plate 2 has a groove 21, and the groove 21 has a sliding groove 22 that matches the slider 32. According to the width of the bed, the support plate 2 is pulled. At this time, one end of the connecting plate 3 rotates and the other end slides, that is, the slider 32 slides along the sliding groove 22, so that the cross angle between the connecting plates 3 changes. The end of the slider 32 away from the connecting plate 3 passes through the sliding groove 22 and is fixed with a fixing block 33. The fixing block 33 enables the slider 32 to slide stably in the sliding groove 22.

[0037] Please see Figures 5-7 In order to lock the distance between the two support plates 2, a cam 5 is rotatably connected to the connecting plate 3. A slot 51 adapted to the cam 5 is opened on the inner side of the groove 21. Rotating the cam 5 into the slot 51 can lock the relative position of the connecting plate 3, thereby fixing the distance between the two support plates 2 and obtaining a stable and appropriately sized bracket.

[0038] Please see Figure 1 and Figure 9 A connecting rope 71 is fixed to the end of the supporting arc column 4 away from the ring 1 and the upper surface of the support plate 2. A clip 7 is fixed to one end of the connecting rope 71. The clip 7 clamps the sheet covering the upper surface of the support, so that the sheet is laid out and fixed on the support, avoiding the accumulation of wrinkles on the support and causing the wrinkles to droop down, which would affect the support effect of the support. The connecting rope 71 makes the clip 7 hang on the supporting arc column 4 and the support plate 2, so that the setting of the clip 7 does not affect the rotation of the connecting plate 3.

[0039] Please see Figure 1 The tray 2 has extensions 23 at both ends. The extensions 23 and the tray 2 are an integral structure, which is used to adapt to the edge of the bed sheet so that the bed sheet can hang down along the edge of the tray 2.

[0040] Please see Figure 1 and Figure 8 A support plate 61 is fixed on the side of the support plate 2 away from the connecting plate 3. An mounting plate 62 is fixed on the end of the support plate 61 away from the support plate 2. The mounting plate 62 has an L-shaped structure. The mounting plate 62 is clamped to the edge of the bed and fixed by screws, which facilitates the installation of the bracket.

[0041] Please see Figure 1 and Figure 8 A cavity 63 is formed between the support plate 61 and the mounting plate 62, which allows ventilation for the patient.

[0042] In use, pull the support plate 2 according to the width of the bed. At this time, one end of the connecting plate 3 rotates and the other end slides, that is, the slider 32 slides along the slide groove 22, so that the cross angle between the connecting plates 3 changes, thereby adjusting the distance between the two support plates 2. Rotate the cam 5 into the slot 51 to lock the relative position of the connecting plates 3, thereby fixing the distance between the two support plates 2. The mounting plate 62 is clamped and fixed to the edge of the bed by screws, thus realizing the installation of the bracket.

[0043] Cover the sheet onto the support frame. The cross frame formed by the two connecting plates 3 provides support. The arched structure of the connecting plate 3, compared to a regular straight rod, can support the sheet to a higher position, providing better support.

[0044] Use clip 7 to hold the sheet covering the upper surface of the frame, so that the sheet is stretched out and fixed on the frame, preventing the sheet from accumulating on the frame and causing the folds to droop, which would affect the support effect of the frame. The ring 1 and the supporting arc column 4 can both provide support, further reducing the gap between the cross frames of the connecting plate 3, preventing the sheet from drooping and contacting the patient's skin, which could cause pressure sores.
