[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the technical solution of the present invention is further described in detail in a non-limiting manner in conjunction with the accompanying drawings and specific implementation methods.
[0023] See Figure 1 and Figure 2The present embodiment discloses a lower limb lifting device, which mainly comprises: a support frame 1, a balancing frame 2, a height-adjusting frame 3 and a supporting cloth 4; wherein the support frame 1, the balancing frame 2 and the height-adjusting frame 3 form a stable triangular structure, and the lower end of the support frame 1 provides two supporting points, and the lower end of the balancing frame 2 also provides two supporting points. The four supporting points make the lower limb lifting device of the present embodiment constitute a stable supporting platform; one end of the balancing frame is movably connected to the lower half of the support frame through a rotating shaft, and the other end provides two supporting points. The supporting cloth 4 is fixedly arranged on the support frame 1 for supporting the patient's lower limbs.
[0024] See Figure 3 The support frame 1 has a square frame structure as a whole, including a left support rod 10, a right support rod 11, an upper connecting rod 12 and a lower connecting rod 13. The four rods are all round rods, which can be made of plastic material, with the characteristics of high cost performance and lightness, and can also be made of alloy material (such as aluminum alloy), with the characteristics of high strength and lightness.
[0025] The shapes, structures and sizes of the left support rod 10 and the right support rod 11 are basically the same, and they are symmetrically arranged. The left and right support rods are structurally divided into a main rod section and a bent rod section. The length of the main rod section is greater than that of the bent rod section. Under normal use, the main rod section is located in the upper section, and the main rod section is designed to be inclined upward. The bent rod section is located in the lower section and contacts the bed surface to provide two support points. As for why the main rod section is not used to be a single rod, and the reason for designing a bent rod section is: it can effectively shorten the oblique extension of the entire support frame and reduce space occupancy. At the same time, when the height is raised to the same level, the bent rod is shorter than the straight rod, reducing material usage.
[0026] The shapes, structures and sizes of the upper connecting rod 12 and the lower connecting rod 13 are also basically the same. The two connecting rods are straight rods, connected between the left and right support rods, and parallel to each other. The two connection points of the upper connecting rod 12 are located on the main rod section, and the two connection points of the lower connecting rod 13 are located on the curved rod section, that is, the position of the upper connecting rod 12 is higher than the lower connecting rod 13, and the upper and lower connecting rods play the role of connecting and stabilizing the left and right support rods. The support cloth 4 is a wear-resistant canvas in a rectangular shape, and the two wide sides are fixedly connected to the left and right support rods respectively.
[0027] See Figure 4 The balance frame 2 includes a left balance bar 20, a right balance bar 21 and a fixed bar 22. Similarly, these three bars are round bars and can be made of plastic material, which has the characteristics of high cost performance and lightness. They can also be made of alloy materials (such as aluminum alloy) with the characteristics of high strength and lightness.
[0028] The shape, structure and size of the left balance bar 20 and the right balance bar 21 are basically the same, and they are arranged symmetrically on the left and right sides. One end (head end) of the left balance bar 20 is rotatably connected to the left support bar 10 through a rotating shaft, and the connection point is located outside the curved rod section. The best connection point is to coincide with the connection point between the lower connecting rod 13 and the left support bar 10; the other end (tail end) is designed to bend downward to raise the overall height, and this end is in contact with the bed surface to provide a support point. Similarly, one end (head end) of the right balance bar 21 is rotatably connected to the right support bar 11 through a rotating shaft, and the connection point is located outside the curved rod section. The best connection point is to coincide with the connection point between the lower connecting rod 13 and the right support bar 11; the other end (tail end) is designed to bend downward to raise the overall height, and this end is in contact with the bed surface to provide a support point. The fixed rod 22 is fixedly connected between the left and right balance bars and close to the tail end, and is used to connect and stabilize the left and right balance bars. After the connection is completed, an acute angle is formed between the support frame 1 and the balance frame 2.
[0029] See Figure 5 The height adjustment frame 3 includes a left height adjustment rod 30, a right height adjustment rod 31 and a limit rod 32. The left height adjustment rod 30 and the right height adjustment rod 31 are flat rods, and the limit rod 32 is a round rod. Similarly, these three rods can be made of plastic material, which has the characteristics of high cost performance and lightness, and can also be made of alloy material (such as aluminum alloy), which has the characteristics of high strength and lightness.
[0030] The shapes, structures and sizes of the left height adjustment rod 30 and the right height adjustment rod 31 are basically the same, and are arranged symmetrically on the left and right sides. One end (the head end) of the left height adjustment rod 30 is rotatably connected to the left support rod 10 through a rotating shaft, and the connection point is located on the outside of the main rod section. The best connection point is to coincide with the connection point between the upper connecting rod 12 and the left support rod 10. One end (the head end) of the right height adjustment rod 31 is rotatably connected to the right support rod 11 through a rotating shaft, and the connection point is located on the outside of the main rod section. The best connection point is to coincide with the connection point between the upper connecting rod 12 and the right support rod 11. The limit rod 32 is fixedly connected between the left and right height adjustment rods, and the connection point is located at the tail end of the left and right height adjustment rods. In addition to being used to connect and stabilize the left and right height adjustment rods, the limit rod 32 is also used to abut against the left balance rod 20 and the right balance rod 21, so that the support frame 1, the balance frame 2 and the height adjustment frame 3 form a stable triangular structure.
[0031] In order to better abut against the limit rod 32, limit slots 23 are provided on the left balance rod 20 and the right balance rod 21 along their respective length directions. Two limit slots corresponding to the left and right sides are a group of limit slots. In this embodiment, two limit slots are provided on each side, so there are two groups of limit slots in total. The limit rod 32 can be detachably inserted into any group of limit slots. When inserted into the limit slot near the tail end, the height of the support frame 1 is reduced; when inserted into the limit slot near the head end, the height of the support frame 1 is increased.
[0032] Since the connection methods adopted between the support frame 1, the balance frame 2 and the height adjustment frame 3 are all rotatable connections, the lower limb raising device of this embodiment is foldable, and the height adjustment frame 3 can be folded in the direction of the angle between the support frame 1 and the balance frame 2. However, since the limit rod 32 of the height adjustment frame 3 spans the support frame 1 and the balance frame 2, the folding fit will be affected. In order to make the folding fit higher, an upward upper protrusion 100 is respectively provided on the main rod section of the left support rod 10 and the right support rod 11, and a semi-arc groove is formed inside the upper protrusion 200; a downward lower protrusion 200 is respectively provided on the left balance rod 20 and the right balance rod 21, and a semi-arc groove is formed inside the lower protrusion 100. After the support frame 1, the balance frame 2 and the height adjustment frame 3 are folded, the limit rod 32 can be inserted into the upper protrusion 100 and the lower protrusion 200, and the folding fit of the support frame 1 and the balance frame 2 is higher. After the entire lower limb lifting device is folded, it can be hung next to the bed. In order to better hang it, two hooks 300 can be set on the outside of the left support rod 10 or the right support rod 11 of the support frame 1.
[0033] See Figure 1-2 As shown, the lower limb raising device of this embodiment also includes an ankle pump training piece 5, so the lower limb raising device of this embodiment has a simple ankle pump training function in addition to the lower limb raising function. Figure 6 The ankle pump training piece includes a left lifting rod 50, a right lifting rod 51, a left elastic band 52, a right elastic band 53 and a foot cover 54, wherein the left lifting rod 50 is fixedly installed on the trunk section of the left support rod 10, and the right lifting rod 51 is fixedly installed on the trunk section of the right support rod 11, one end of the left elastic band 52 is connected to the left lifting rod 50, and the other end is connected to the left side of the foot cover 54, one end of the right elastic band 53 is connected to the right lifting rod 51, and the other end is connected to the right side of the foot cover 54, and the foot cover 54 is in a circular shape for the patient's foot to pass through.
[0034] When in use, the lower limb raising device of this embodiment is unfolded and placed on the bed, and the limit rod 32 is inserted into the corresponding limit slot 23 according to the required lifting height. The patient lies on his back and places his calf on the support cloth 4, thus completing the lower limb raising action. When the patient needs to perform ankle pump training, the sole of the foot can be passed through the foot cover 54, and under the elastic tension of the left elastic band 52 and the right elastic band 53, the sole of the foot can be swung back and forth to perform resistance ankle pump training.
[0035] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
