Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a U-shaped pad for lower limb elevation. Background Technology

[0002] Patients who are bedridden for a long time or have foot injuries often experience significant swelling in their lower limbs due to slow blood return to the heart. Swelling in the lower limbs can easily lead to problems such as compartment syndrome. It is necessary to elevate the lower limbs to prevent edema. Clinically, pillows or cotton pads are often used to elevate the patient's lower limbs. However, pillows and cotton pads have poor support, are easily deformed, and do not conform to the shape of the lower limbs, so they cannot fully support the patient's lower limbs.

[0003] Most existing lower limb elevation pads are fixed in place and have a simple structure, making it difficult to adjust and fix the lower limbs according to different users. Therefore, this utility model proposes a U-shaped lower limb elevation pad to solve the above problems. Utility Model Content

A plurality of lower limb limiting mechanisms are arranged transversely at equal intervals on the top of the pad body. The lower limb limiting mechanism includes a second lower limb inverted semi-circular plate or a third lower limb inverted semi-circular plate. An inverted arc-shaped pressure plate is arranged below the second lower limb inverted semi-circular plate. A third lower limb rubber pad is fixedly arranged at the bottom of the inverted arc-shaped pressure plate. A fourth lower limb rubber pad is fixedly arranged at the bottom of the third lower limb inverted semi-circular plate.

[0006] Furthermore, the lower limb limiting mechanism includes a second lower limb inverted semi-circular plate. Circular plate support rods are fixedly installed on both sides of the bottom of the second lower limb inverted semi-circular plate. The circular plate support rods are fixedly installed on the pad body. A lifting screw is installed on the top of the second lower limb inverted semi-circular plate.

[0025] Example 1

[0026] Please see Figure 1-3 A U-shaped pad for lower limb elevation includes a pad body 1, which can be made of a slightly elastic material, such as a rigid sponge or a high-density sponge. The top of the pad body 1 has a transversely through-hole U-shaped groove 13 for lower limbs. The patient's lower limb is placed in the U-shaped groove 13. A second lower limb rubber pad 22 is placed at the bottom of the U-shaped groove 13. Several lower limb limiting mechanisms are arranged transversely at equal intervals on the top of the pad body 1. The lower limb limiting mechanisms can conveniently limit the patient's lower limb after it is placed in the U-shaped groove 13, and the limiting space can be adjusted.

[0027] Specifically, the lower limb limiting mechanism includes a first lower limb inverted semicircular plate 3. A first lower limb rubber pad 4 is fixedly installed on the inner side of the first lower limb inverted semicircular plate 3. The first lower limb rubber pad 4 prevents excessive force between the first lower limb inverted semicircular plate 3 and the lower limb from causing injury to the lower limb. Lifting rod mechanisms 5 are fixedly installed on both sides of the bottom of the first lower limb inverted semicircular plate 3. The lifting rod mechanism 5 is installed and fixed to the pad body 1. The lifting adjustment mechanism 5 is used to adjust the size of the limiting space.

[0028] The lifting rod mechanism 5 includes a lifting fixed rod 54, which is fixedly installed in the first groove 6. The first groove 6 is located on the top of the pad body 1. A lifting movable rod 51 is movably inserted into the top of the lifting fixed rod 54. The top end of the lifting movable rod 51 is fixedly connected to the first lower limb inverted semicircular plate 3. A fixing screw 53 is provided on the upper outer wall of the lifting fixed rod 54. Multiple fixing screw holes 52 are opened longitudinally at equal intervals on the side wall of the lifting movable rod 51. The fixing screw 53 is threadedly engaged with the lifting fixed rod 54. The lifting movable rod 51 is fixed by screwing it into the corresponding fixing screw hole 52 through the fixing screw 53. Then, the depth of the lifting movable rod 51 inserted into the lifting fixed rod 54 is adjusted so that the first lower limb inverted semicircular plate 3 rests against the top of the lower limb. The lifting movable rod 51 is then fixed by screwing it into the corresponding fixing screw hole 52 through the fixing screw 53, thus limiting and fixing the lower limb in the lower limb U-shaped groove 13.

[0029] This invention utilizes a structure including a second lower limb rubber pad 22, a first lower limb inverted semicircular plate 3, a lower limb U-shaped groove 13, a lifting and movable rod 51, and a lifting and fixing rod 54. The patient's lower limb is placed within the lower limb U-shaped groove 13. The depth of the lifting and movable rod 51 inserted into the lifting and fixing rod 54 is adjusted so that the first lower limb inverted semicircular plate 3 rests against the upper part of the lower limb. After adjusting to a suitable limiting space, the lifting and movable rod 51 is then fixed by screwing the fixing screw 53 into the corresponding fixing screw hole 52, thus limiting and fixing the lower limb within the lower limb U-shaped groove 13. The first lower limb rubber pad 4 prevents excessive force between the first lower limb inverted semicircular plate and the lower limb from causing injury. This invention solves the problem that most existing lower limb elevation pads are fixed in place, have simple structures, and are difficult to adjust and fix according to different users.

[0030] Example 2

[0031] Please see Figure 4-5The difference from Embodiment 1 lies in the shape of the lower limb limiting mechanism. The lower limb limiting mechanism includes a second lower limb inverted semi-circular plate 8. Circular plate support rods 7 are fixedly installed on both sides of the bottom of the second lower limb inverted semi-circular plate 8. The circular plate support rods 7 are fixedly installed on the pad body 1. An inverted arc-shaped pressure plate 9 is installed below the second lower limb inverted semi-circular plate 8. A third lower limb rubber pad 14 is fixedly installed at the bottom of the inverted arc-shaped pressure plate 9. The third lower limb rubber pad 14 and the second lower limb rubber pad 22 are installed to prevent excessive force between the inverted arc-shaped pressure plate 9 and the lower limb from causing injury to the lower limb.

[0032] A lifting screw 15 is provided at the top of the second lower limb inverted semi-circular plate 8. The lifting screw 15 is threadedly engaged with the second lower limb inverted semi-circular plate 8. The bottom end of the lifting screw 15 is rotatably connected to the inverted arc-shaped pressure plate 9 through a rotating shaft 10. Telescopic rods 12 are fixedly provided on both sides of the top of the inverted arc-shaped pressure plate 9. The end of the telescopic rod 12 away from the inverted arc-shaped pressure plate 9 is fixedly provided in the second groove 11. The second groove 11 is opened at the bottom of the second lower limb inverted semi-circular plate 8. The patient's lower limb is placed in the lower limb U-shaped groove 13. The lifting screw 15 is tightened downwards. Under the action of the rotating shaft 10 and the telescopic rod 12, the inverted arc-shaped pressure plate 9 is moved downwards, so that the inverted arc-shaped pressure plate 9 is pressed against the upper part of the lower limb, thereby limiting and fixing the lower limb in the lower limb U-shaped groove 13. The height of the inverted arc-shaped pressure plate 9 can be adjusted to limit the lower limb and can be adjusted to a suitable limiting space, making adjustment more convenient.

[0033] This invention utilizes a structure consisting of a circular plate support rod 7, a second lower limb inverted semi-circular plate 8, an inverted arc-shaped pressure plate 9, a third lower limb rubber pad 14, and a lifting screw 15. The patient's lower limb is placed within the lower limb U-shaped groove 13. Tightening the lifting screw 15 downwards causes the inverted arc-shaped pressure plate 9 to move downwards under the action of the rotating shaft 10 and the telescopic rod 12, so that the inverted arc-shaped pressure plate 9 rests against the upper part of the lower limb, thus fixing the lower limb within the lower limb U-shaped groove 13. The third lower limb rubber pad 14 and the second lower limb rubber pad 22 prevent excessive force between the inverted arc-shaped pressure plate and the lower limb from causing injury. This invention solves the problem that most existing lower limb elevation pads are fixed in place, have simple structures, and are difficult to adjust and fix according to different users.

[0034] Example 3

[0035] Please see Figure 6-8 The difference from Embodiment 1 lies in the shape of the lower limb limiting mechanism. The lower limb limiting mechanism includes a third lower limb inverted semicircular plate 16. A fourth lower limb rubber pad 17 is fixedly provided at the bottom of the third lower limb inverted semicircular plate 16. The second lower limb rubber pad 22 and the fourth lower limb rubber pad 17 are provided to prevent excessive force between the third lower limb inverted semicircular plate 16 and the lower limb from causing damage to the lower limb.

[0036] The third lower limb inverted semicircular plate 16 is fixedly provided with first fixing straps 18 at both ends. The bottom of the first fixing straps 18 is fixedly provided with first Velcro straps 19. The pad body 1 is covered with a protective cover 2. The top two sides of the protective cover 2 are fixedly provided with second fixing straps 21. The top of the second fixing straps 21 is fixedly provided with second Velcro straps 20. The first Velcro straps 19 and the second Velcro straps 20 are glued and fixed to each other. The patient's lower limb is placed in the lower limb U-shaped groove 13. The position of the first Velcro straps 19 and the second Velcro straps 20 is adjusted as needed so that the third lower limb inverted semicircular plate 16 is against the upper part of the lower limb, thus limiting the lower limb in the lower limb U-shaped groove 13.

[0037] The protective cover 2 has a zipper 23 on the front. By opening the zipper 23, the pad body 1 can be taken out from the protective cover 2, so that the protective cover 2 can be cleaned. The lower limbs are restricted by the first Velcro tape 19 and the second Velcro tape 20, which facilitates quick restriction.

[0038] This invention, through the inclusion of a fourth lower limb rubber pad 17, a first fixing strap 18, a protective cover 2, a first Velcro strap 19, and a second Velcro strap 20, places the patient's lower limb within a U-shaped groove 13. The U-shaped groove 13 is ergonomically designed. The positions of the first Velcro strap 19 and the second Velcro strap 20 can be adjusted as needed, so that the third lower limb inverted semi-circular plate 16 rests against the upper part of the lower limb, thus securing the lower limb within the U-shaped groove 13. The second lower limb rubber pad 22 and the fourth lower limb rubber pad 17 prevent excessive force between the third lower limb inverted semi-circular plate 16 and the lower limb, thus avoiding injury. A zipper 23 allows the pad body 1 to be removed from the protective cover 2 for cleaning, improving operational convenience.
