Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical and nursing device technology, and more specifically, to a sacrococcygeal pressure ulcer prevention nursing device. Background Technology
[0002] The sacrococcygeal region is a high-risk area for pressure ulcers, especially among people who are bedridden or wheelchair-bound for extended periods. Sustained pressure on this area obstructs blood circulation, and factors such as damp skin and poor nutrition can easily lead to pressure ulcers. Early signs of pressure ulcers in the sacrococcygeal region include redness of the skin; in severe cases, tissue necrosis can occur, causing not only pain but also infection and potentially life-threatening complications. Early prevention and treatment are crucial.
[0003] For the treatment of pressure ulcers in the sacrococcygeal region of long-term bedridden patients, pressure-resistant nursing devices are needed to prevent the ulcers from worsening. Currently, these devices are mainly placed under the patient's buttocks to keep the sacrococcygeal region as suspended as possible. However, this doesn't effectively restrain the patient's body, and patients often unconsciously turn over during sleep, causing pressure on the sacrococcygeal region, which is detrimental to the treatment of pressure ulcers. Therefore, we propose a sacrococcygeal pressure-resistant nursing device. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a sacrococcygeal pressure ulcer prevention nursing device to solve the technical problem that patients tend to turn over involuntarily during sleep at night, causing compression of the sacrococcygeal region, which is not conducive to ensuring the treatment of sacrococcygeal pressure ulcers.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sacrococcygeal pressure ulcer prevention nursing device, comprising an adjustment mechanism, a nursing mechanism mounted on the adjustment mechanism, and a limiting mechanism mounted on the nursing mechanism. The adjustment mechanism includes a support base, the lower end of which has an installation cavity. A bidirectional screw is rotatably mounted in the installation cavity. An adjustment disc connected to the axis of the bidirectional screw is rotatably mounted on the side end of the support base. A moving block is symmetrically threaded on the bidirectional screw. A connecting plate is mounted on the front end of the moving block. The nursing mechanism includes a nursing seat, which has two symmetrically distributed nursing seats. A rotating component is provided on the side end of the nursing seat. The limiting mechanism includes a limiting plate rotatably mounted on the side end of the nursing seat. The rotating component includes an installation plate and an installation rod provided at the front end of the installation plate. An installation component is provided on the side end of the limiting plate and is sleeved on the installation rod.
[0006] Preferably, the front end of the support base has an adjustment port communicating with the mounting cavity, the connecting plate extends out from the adjustment port, and the two nursing seats are respectively installed at the front end of the connecting plate.
[0007] Preferably, the upper end of the nursing seat is provided with a groove, the groove is a downwardly concave arc surface, and a suspension groove is provided in the groove, with a suspension hole formed between two suspension grooves.
[0008] Preferably, the limiting plate includes a first limiting part, an arc-shaped part, and a second limiting part, wherein the arc-shaped part is disposed at the upper end of the first limiting part, and the second limiting part is disposed at the end of the arc-shaped part.
[0009] Preferably, the upper surface of the support base is curved, the lower end of the first limiting part is curved, the curvature of the lower end of the first limiting part matches the curvature of the upper end of the support base, and the first limiting part fits against the upper end of the support base.
[0010] Preferably, the arc-shaped portion curves inward from bottom to top, the second limiting portion is horizontally positioned, a connecting rod is installed at the upper end of the second limiting portion, and a tension rope is hung between the connecting rods.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model designs a limiting plate structure, which consists of a first limiting part, an arc-shaped part, and a second limiting part. The arc shape at the lower end of the first limiting part matches the arc shape at the upper end of the support seat, allowing it to fit tightly against the support seat and limit the patient's sides, preventing the patient from falling out of the nursing device. The arc-shaped part bends inward from bottom to top, cooperating with the horizontally set second limiting part to limit the patient's sides and top, restricting the patient from turning over and avoiding pressure on the sacrum and coccyx caused by turning over. This ensures the treatment effect of sacral and coccygeal pressure ulcers and solves the problem that patients tend to turn over involuntarily during sleep at night, causing pressure on the sacrum and coccyx, which is not conducive to the treatment of sacral and coccygeal pressure ulcers.
[0013] 2. This utility model also features a bidirectional screw structure. The bidirectional screw can adjust the distance between the two nursing seats according to the body shape of different patients, which enhances the adaptability of the nursing device to different patient body widths and improves the comfort and effectiveness of use.
[0014] 3. This utility model also designs a support seat and a nursing seat structure. The upper arc surface of the support seat can support the patient's waist, protect the patient's lumbar spine, and provide support from the outside of the sacrum and coccyx, thereby reducing the pressure on the sacrum and coccyx. The groove on the nursing seat adopts a downward concave arc surface design, in which the patient's buttocks can sink into, reducing the pressure on the buttocks and thus preventing pressure on the sores. At the same time, the suspended groove in the groove and the suspended hole formed between two suspended grooves can keep the patient's sacrum and coccyx in a suspended state, effectively reducing the pressure on the sacrum and coccyx, and helping to prevent and treat sacrum and coccyx pressure sores.

Detailed Implementation
[0022] like Figures 1 to 6 As shown, this utility model relates to a sacrococcygeal pressure ulcer prevention nursing device, including an adjustment mechanism 100, a nursing mechanism 200 mounted on the adjustment mechanism 100, and a limiting mechanism 300 mounted on the nursing mechanism 200. The adjustment mechanism 100 includes a support base 101, with a mounting cavity 102 at the lower end of the support base 101. A bidirectional screw 103 is rotatably mounted in the mounting cavity 102. An adjustment disc 104, which is axially connected to the bidirectional screw 103, is rotatably mounted on the side end of the support base 101. A movable block 105 is symmetrically threaded and mounted on a connecting plate 107 at its front end. The nursing mechanism 200 includes a nursing seat 201, with two symmetrically distributed seats. A rotating component 205 is located on the side of each nursing seat 201. A limiting mechanism 300 includes a limiting plate 301 rotatably mounted on the side of the nursing seat 201. The rotating component 205 includes a mounting plate and a mounting rod at the front end of the mounting plate. A mounting component 302 is located on the side of the limiting plate 301 and is fitted onto the mounting rod. This invention keeps the patient's sacrum and coccyx suspended and restricts unconscious turning during sleep, effectively preventing pressure ulcers in the sacrum and coccyx and ensuring the treatment effect of sacral and coccygeal pressure ulcers.
[0023] Specifically, the front end of the support base 101 has an adjustment port 106 that communicates with the mounting cavity 102. The connecting plate 107 extends out from the adjustment port 106, and the two nursing seats 201 are respectively installed at the front end of the connecting plate 107. The adjustment port 106 facilitates the extension of the connecting plate 107 to connect with the nursing seats 201.
[0024] Furthermore, the upper end of the nursing seat 201 is provided with a support groove 202, which is a downwardly concave arc surface. A suspension groove 203 is formed within the support groove 202, and a suspension hole 204 is formed between two suspension grooves 203. The downwardly concave arc surface design of the support groove 202 on the nursing seat 201 allows the patient's buttocks to sink into it, reducing pressure on the buttocks and preventing pressure on the sores. Simultaneously, the suspension grooves 203 within the support groove 202 and the suspension hole 204 formed between two suspension grooves 203 keep the patient's sacrum and coccyx in a suspended state, effectively reducing pressure on the sacrum and coccyx and helping to prevent and treat sacral and coccygeal pressure sores.
[0025] It is worth noting that the limiting plate 301 includes a first limiting part 303, an arc-shaped part 304, and a second limiting part 305. The arc-shaped part 304 is located at the upper end of the first limiting part 303, and the second limiting part 305 is located at the end of the arc-shaped part 304. The arc-shaped part 304 curves inward from bottom to top, and cooperates with the horizontally positioned second limiting part 305 to limit the patient's side and top, restricting the patient from turning over and avoiding compression of the sacrum and coccyx caused by turning over.
[0026] It is worth noting that the upper surface of the support base 101 is curved, and the lower end of the first limiting part 303 is also curved. The curvature of the lower end of the first limiting part 303 matches the curvature of the upper end of the support base 101, and the first limiting part 303 fits snugly against the upper end of the support base 101. The curvature of the lower end of the first limiting part 303 matches the curvature of the upper end of the support base 101, allowing it to fit tightly against the support base 101 and limiting the patient's sides, preventing the patient from falling out of the nursing device.
[0027] It is worth noting that the arc-shaped portion 304 curves inward from bottom to top, and the second limiting portion 305 is horizontally positioned. A connecting rod 306 is installed at the upper end of the second limiting portion 305, and a tension rope 307 is connected between the connecting rods 306. The connecting rods 306 and the tension rope 307 can fix the two limiting plates 301, preventing the limiting plates 301 from rotating and allowing the limiting plates 301 to limit the patient's body.
[0028] Working Principle: This embodiment provides a sacrococcygeal pressure ulcer prevention nursing device. In use, firstly, according to the patient's body width, the adjusting disc 104 is rotated to rotate the bidirectional screw 103. When the bidirectional screw 103 rotates, the two moving blocks 105 will move in a straight line relative to or opposite to each other along the bidirectional screw 103, thereby adjusting the distance between the two nursing seats 201 to fit the patient's body width. Then, soft pads are placed on the upper ends of the support seat 101 and the nursing seat 201, and the soft pads are recessed into the brackets 202. When the patient lies on the nursing device, their buttocks are recessed into the brackets 202 of the nursing seat 201, reducing pressure on the buttocks. The sacrococcygeal region is located at the suspension hole and is in a suspended state, reducing the pressure on the sacrococcygeal region. The support seat 101 can support the patient's waist and protect the lumbar spine. Then, the limiting plate 301 is rotated to a straight state (e.g., ...). Figure 1 and Figure 6 Furthermore, a tension rope 307 is installed between the connecting rods 306 to fix the positions of the two limiting plates 301. When the limiting plates 301 are in a straight state, the arc-shaped design of the first limiting part 303 of the limiting plate 301 can fit against the upper end of the support base 101, so that the limiting plate 301 can limit the sides of the patient's body and prevent the patient from falling out of the nursing device. The arc-shaped part 304 of the limiting plate 301 bends inward from bottom to top, and together with the second limiting part 305, it can limit the sides and top of the patient's body, which can restrict the patient from turning over and prevent the sacrococcygeal region from being squeezed when the patient turns over, thereby ensuring the treatment effect of the sacrococcygeal pressure ulcer. With the cooperation of these, the sacrococcygeal pressure ulcer can be well cared for.
