Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning pad technology, and in particular to a novel positioning pad. Background Technology
[0002] After lower limb surgery, patients need to use footrests to elevate the affected limb to promote venous blood return and reduce edema. However, due to prolonged wearing of casts and braces, the weight of the legs and feet increases, and prolonged lying down can easily cause pressure injuries to the heels. In current clinical practice, there are usually only single positioning pads to prevent pressure on the heels, or single positioning pads to elevate the affected limb. In some cases, towels, pillows, and other substitutes are often used to reduce pressure on the heels. This approach is neither aesthetically pleasing nor convenient, and it also reduces patient comfort.
[0003] In the existing technology, such as the Chinese patent with authorization announcement number CN215740087U, a modified lower limb positioning pad is disclosed, which uses Velcro to attach and position the recess to provide support for both the lower limbs and the heels.
[0004] However, the above-mentioned technical solutions still have at least the following drawbacks: they can only raise the support height of the lower limbs by adjusting the support position of the heels, which can easily increase the pressure on the heels; the positioning pad as a whole lacks adjustment of the support height, making it difficult to meet the needs of patients of different body types for the height of lower limb elevation. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a novel positioning pad, comprising:
[0006] A base, wherein an upward-opening inclined groove is formed inside the base, the inclined groove being used to restrict the pad from moving up and down along the inclined direction of the inclined groove;
[0007] A pad, which is slidably mounted on the base via the inclined groove, and the upper surface of the pad has a curved groove for accommodating the affected limb;
[0008] A drive assembly is disposed between the bottom wall of the inclined groove and the lower surface of the pad, and the drive assembly is used to drive the pad to extend into or out of the platform.

[0010] A push plate is slidably connected to the inner bottom wall of the inclined groove. A plurality of balls are rotatably mounted on the upper surface of the push plate, and an inclined guide surface is formed on the lower surface of the pad. The plurality of balls slide in contact with the inclined guide surface.
[0011] A threaded push rod extends through the base into the inclined groove. One end of the threaded push rod is rotatably mounted on the push plate, and the other end of the threaded push rod forms a first turntable.
[0012] More preferably, the drive assembly further includes a spring, the bottom end of which is fixedly connected to the inner bottom wall of the inclined groove, and the top end of which is fixedly connected to the pad.
[0013] More preferably, the pedestal is a trapezoidal body, a supporting inclined surface is formed on one side of the pedestal, an extending inclined surface is formed on the side of the pad near the supporting inclined surface, and a first flexible pad is provided on the surface of the curved groove, the first flexible pad extending to the supporting inclined surface through the extending inclined surface.
[0014] Further preferred options include:
[0015] Heel seat, which is slidably mounted in the curved groove of the pad;
[0016] An adjustment component is mounted on the pad and is used to lock the heel seat in a curved groove.
[0017] More preferably, a support block is formed on one side of the heel seat, a positioning opening is formed on the support block, and a clearance groove is formed on the upper surface of the heel seat near the support block.
[0018] More preferably, the adjustment assembly includes a guide rod, which is fixedly installed at the front end of the right side of the pad, and a fixing plate is formed on the right side of the heel seat, with the guide rod passing through the front end of the fixing plate.

[0021] More preferably, the upper surface of the heel seat is provided with a second flexible pad.
[0022] More preferably, a felt layer is fixedly installed on the lower surface of the pedestal.
[0023] Compared with existing technologies, this utility model has a clever structure and is easy to operate. Through the cooperation of the base and the pad, the pad is driven by the drive component to move up and down along the inclined groove, which can flexibly adjust the support height of the pad. This allows the curved groove that accommodates the affected limb to flexibly elevate the patient's lower limb according to different body types and patient needs, effectively improving the flexibility and adaptability of use. By adjusting the cooperation of the adjustment component and the heel seat, the support position of the heel seat in the curved groove can be flexibly adjusted, thereby better adapting to the heel support needs of patients of different body types, ensuring the stability of the support, and also better reducing the pressure on the heel when elevating the affected limb, better meeting the actual needs of patients.

Detailed Implementation
[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0032] Depend on Figures 1 to 5 The present invention relates to a novel positioning pad, comprising:
[0033] The base 1 has an upward-opening inclined groove 2 inside, which restricts the pad 3 from moving up and down along the inclined direction of the inclined groove 2.
[0034] The pad 3 is slidably mounted on the base 1 via the inclined groove 2, and the upper surface of the pad 3 has a curved groove 4 for accommodating the affected limb.
[0035] The drive assembly is located between the bottom wall of the inclined groove 2 and the lower surface of the pad 3. The drive assembly is used to drive the pad 3 to extend into or out of the platform 1.
[0036] In these embodiments, the cross-section of the inclined groove 2 in the base 1 is a parallelogram. The pad 3 can stably extend into or out of the base 1 by moving along the inclined groove 2. Through the cooperation of the base 1 and the pad 3, the pad 3 is driven by the drive component to move up and down along the inclined groove 2, so that the pad 3 can extend into or out of the base 1. This allows the support height of the pad 3 to be flexibly adjusted, so that the curved groove 4 that accommodates the affected limb can flexibly lift the patient's lower limb according to the patient's body size and needs, effectively improving the flexibility and adaptability of use.
[0037] In some embodiments of a novel positioning pad, the drive assembly includes:
[0038] Push plate 5 is slidably connected to the inner bottom wall of inclined groove 2. Several balls 6 are rotatably installed on the upper surface of push plate 5. An inclined guide surface 7 is formed on the lower surface of pad 3. Several balls 6 slide in contact with the inclined guide surface 7.
[0039] The threaded push rod 8 passes through the base 1 and extends into the inclined groove 2. One end of the threaded push rod 8 is rotatably mounted on the push plate 5, and the other end of the threaded push rod 8 forms a first turntable.
[0040] In these embodiments, the top of the push plate 5 has a groove for mounting the ball bearing 6, which can roll freely on the push plate 5. A rotating groove is formed on the side of the push plate 5, and one end of the threaded push rod 8 is rotatably mounted in the rotating groove via its rotating head. The threaded push rod 8 is threadedly engaged with the base 1. Rotating the first turntable drives the threaded push rod 8 to rotate, simultaneously causing the threaded push rod 8 to extend into or out of the inclined groove 2, thereby causing the push plate 5 to slide along the inner bottom wall of the inclined groove 2. Then, through the cooperation of the push plate 5 and the inclined guide surface 7, the push plate 5 drives the pad 3 to extend into or out of the base 1 during its sliding process. The inclined guide surface 7 is lower on the left and higher on the right. During the movement of the push plate 5, the ball bearing 6 at its top slides into contact with the inclined guide surface 7, thereby lifting the pad 3.
[0041] In some embodiments of the novel positioning pad, the drive assembly further includes a spring 9, the bottom end of which is fixedly connected to the inner bottom wall of the inclined groove 2, and the top end of which is fixedly connected to the pad 3.
[0042] In these embodiments, when the pad 3 extends out of the platform 1, the spring 9 is stretched by the elastic force of the spring 9. When it is necessary to lower the height of the pad 3, the threaded push rod 8 drives the push plate 5 to reset. As the push plate 5 moves, under the action of the elastic force of the spring 9, the pad 3 automatically extends into the platform 1, thereby flexibly adjusting the pad 3 to extend into or out of the platform 1, making the operation more convenient and flexible.
[0043] In some embodiments of a novel positioning pad, the pedestal 1 is trapezoidal, a supporting inclined surface 10 is formed on one side of the pedestal 1, an extending inclined surface 11 is formed on the side of the pad 3 near the supporting inclined surface 10, and a first flexible pad is provided on the surface of the curved groove 4, which extends to the supporting inclined surface 10 through the extending inclined surface 11.
[0044] In these embodiments, the first flexible pad (not shown in the figure) on the pad 3 and the base 1 can better support the patient and improve the comfort of use. The first flexible pad is fixedly installed on the surface of the curved groove 4, and its movable part is sequentially mounted on the extension slope 11 to the support slope 10, ensuring that the first flexible pad can stably cover the pad 3 and the base 1 when the height of the pad 3 is adjusted, which effectively improves the comfort of use. The first flexible pad can be any one of cotton pad, latex pad, or rubber pad.
[0045] In some embodiments of this novel positioning pad, it also includes:
[0046] Heel seat 12, which is slidably installed in the curved groove 4 of the pad 3;
[0047] An adjustment component is mounted on the pad 3 and is used to lock the heel seat 12 into the curved groove 4.
[0048] In these embodiments, the heel seat 12 can stably support and place the patient's heel. Through the cooperation of the adjustment component and the heel seat 12, the adjustment component can flexibly adjust the support position of the heel seat 12 in the curved groove 4, thereby better adapting to the usage needs of patients of different body types, ensuring the stability of the support, and also better reducing the pressure on the heel when raising the affected limb, thus better meeting the actual usage needs of patients.
[0049] It should be understood that in this utility model, the heel part includes the ankle and the heel.
[0050] In some embodiments of a novel positioning pad, a support block 13 is formed on one side of the heel seat 12, a positioning opening 14 is formed on the support block 13, and a relief groove 15 is formed on the upper surface of the heel seat 12 near the support block 13.
[0051] In these embodiments, the positioning opening 14 is a concave arc surface adapted to the ankle, and the relief groove 15 is a spherical groove adapted to the heel. Through the cooperation of the positioning opening 14 and the relief groove 15, the patient's heel can be supported more stably, effectively reducing the feeling of pressure.
[0052] In some embodiments of a novel positioning pad, the adjustment assembly includes a guide rod 16, which is fixedly installed at the front end of the right side of the pad 3. A fixing plate 17 is formed on the right side of the heel seat 12, and the guide rod 16 passes through the front end of the fixing plate 17.
[0053] In some embodiments of a novel positioning pad, the adjustment assembly further includes a threaded positioning rod 18, which is rotatably mounted on the rear end of the right side of the pad 3. The threaded positioning rod 18 passes through the rear end of the fixing plate 17, and the threaded positioning rod 18 is threadedly connected to the fixing plate 17.
[0054] A support plate 19 is fixedly connected to the right end of the guide rod 16, and the threaded positioning rod 18 passes through the support plate 19.
[0055] In these embodiments, one end of the threaded positioning rod 18 is rotatably mounted in the groove of the pad 3 via its rotating head, and the threaded positioning rod 18 is rotatably mounted to the support plate 19 via a rotating shaft. The guide rod 16 and the fixing plate 17 are slidably mounted, and the threaded positioning rod 18 and the fixing plate 17 are threadedly mounted. A second turntable is formed at the right end of the threaded positioning rod 18. Rotating the second turntable causes the threaded positioning rod 18 to rotate, and then, in conjunction with the guide rod 16, causes the fixing plate 17 to move, thereby causing the heel seat 12 to move within the curved groove 4. At the same time, it can also fix the heel seat 12 in an appropriate position within the curved groove 4, making the adjustment more flexible and the support more stable.
[0056] In some embodiments of a novel positioning pad, the upper surface of the heel seat 12 is provided with a second flexible pad.
[0057] In these embodiments, the second flexible pad is uniformly and fixedly laid on the heel seat 12 (not shown in the figure). The second flexible pad can effectively improve the comfort of use. The second flexible pad can be any one of cotton pad, latex pad, or rubber pad.
[0058] In some embodiments of a novel positioning pad, a felt layer is fixedly installed on the lower surface of the base 1.
[0059] In these embodiments, the felt layer is fixedly laid on the lower surface of the base 1 (not shown in the figure). When the present invention is placed on the hospital bed, the felt layer can effectively increase the friction with the hospital bed, which is beneficial to improving the stability of the placement and use.
