Some patients who are bedridden for a long time, people with lower limb blood circulation problems, and patients after hip fracture surgery generally need to use side-lying knee support to provide support when lying on their side.

[0003] Existing side-lying knee supports typically adopt a long strip or U-shaped design to accommodate the gap between the knees and provide stable support. However, under normal circumstances, there are gaps between the two thighs and the two calves when lying on one's side. A single side-lying knee support can only provide support for the thigh or calf individually, and the gap between the thigh and calf is different when lying on one's side. Users need to use two side-lying knee supports of different sizes, or use pillows or other aids. As a result, users may need multiple side-lying knee supports or aids when lying on their side, which is quite inconvenient.

[0004] Therefore, this utility model proposes an inflatable side-lying knee support. Utility Model Content

[0033] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] like Figure 1-8 As shown, an inflatable side-lying knee support includes:

[0035] The support block 11 and two rotating blocks 12 are provided. The rotating blocks 12 are rotatably disposed inside the support block 11. Contact blocks 13 are slidably disposed inside both the support block 11 and the rotating blocks 12.

[0036] The contact block 13 comes into contact with the human body, and an elastic layer is provided on the side of the contact block 13 that comes into contact with the human body;

[0037] Two central rods 14 are fixedly connected to the support block 11. The central rods 14 are close to the edge of the support block 11. The rotating block 12 has a rotating groove 15 on its surface, which is adapted to the central rods 14. Through the central rods 14 and the rotating grooves 15, the rotating block 12 can be rotated at a fixed point inside the support block 11. The central rods 14 are close to the edge of the support block 11, which ensures that the rotating block 12 can rotate and protrude into the support block 11, extending the position of the support block 11 and thus providing more contact area with the human body.

[0038] A plurality of protruding shafts 16 are arranged in a circular array on the surface of the central rod 14. A plurality of embedded shafts 17 are fixedly connected inside the rotating groove 15. Each embedded shaft 17 contacts an adjacent protruding shaft 16. The number of protruding shafts 16 is an integer multiple of the number of embedded shafts 17, and the protruding shafts 16 and embedded shafts 17 are of the same height. The height difference between the central rod 14 and the rotating block 12 is equal to the height of the protruding shafts 16. Through the central rod 14, which is taller than the rotating block 12, the rotating block 12 can slide on the surface of the central rod 14. The protruding shafts 16 and embedded shafts 17 are arranged between the two and can contact each other. Thus, when the rotating block 12 slides to a certain position, the rotating block 12 cannot rotate around the central rod 14 as the center.

[0039] In practical application, this inflatable side-lying knee support features a rotatable protruding rotating block 12 inside the support block 11. Both the support block 11 and the rotating block 12 have contact blocks 13 with elastic layers on their surfaces. By sliding the rotating block 12 inside the support block 11, the support area with the user can be increased, allowing it to contact multiple areas of the thigh and calf, providing a more comfortable experience. Furthermore, the position of the rotating block 12 after rotation can be limited by a simple change in height between the rotating block 12 and the support block 11. This allows for quick adjustment of the angle between the rotating block 12 and the support block 11, enabling the user to adjust the angle to support their side-lying position according to their condition, making it convenient to use.

[0040] In some specific implementations, each contact block 13 has an inflation groove 21 inside, and a telescopic tube 22 is fixedly connected to the surface of the inflation groove 21. The contact block 13 is made of elastic material, and air plugs 23 are detachably connected to the surfaces of the support block 11 and the rotating block 12. The air plugs 23 are adapted to the telescopic tubes 22. Through the inflation grooves 21 and telescopic tubes 22 on the surface of the contact block 13, combined with its own elasticity, the state of the contact block 13 and the elasticity of its contact surface with the user can be changed by inflation, which is convenient to adjust according to the user's needs.

[0041] In a further embodiment, a plurality of adjusting blocks 31 are fixedly connected to the surface of each contact block 13, and a plurality of operating rods 32 are rotatably connected inside each of the support block 11 and the rotating block 12, and each operating rod 32 is threadedly connected to the adjusting block 31; through the threaded connection between the adjusting block 31 and the operating rod 32, both the support block 11 and the rotating block 12 can change the position of the contact block 13 by rotating the operating rod 32, thereby adjusting the distance between the two opposing contact blocks 13 according to different user needs;

[0042] In a further embodiment, each of the operating levers 32 is fixedly connected to a synchronous pulley 33, and a synchronous belt 34 is driven between the two synchronous pulleys 33; the two operating levers 32 are arranged on the diagonal of the contact block 13; through the synchronous pulleys 33 and the synchronous belt 34 on the surface of the operating levers 32, the rotation of a single operating lever 32 drives the rotation of all operating levers 32 inside the support block 11 or the rotating block 12, thereby ensuring that the elastic contact block 13 moves vertically inside the support block 11 and the rotating block 12, and is in a horizontal state as a whole;

[0043] It should be noted that both the support block 11 and the rotating block 12 have L-shaped grooves inside, which are adapted to the synchronous belt 34, and the inflection point is arc-shaped.

[0044] In some specific implementations, the support block 11 includes a connecting block and a splitting block, and both the connecting block and the splitting block are slidably provided with contact blocks 13, and both the connecting block and the splitting block are rotatably provided with rotating blocks 12.

[0045] The surface of the connecting block is provided with a combination groove 41, and a connecting shaft 42 is fixedly connected to the side of the connecting block away from the contact block 13. The surface of the split block is fixedly connected with a combination block 43, which is adapted to the combination groove 41. The surface of the split block is provided with a connecting groove 44, which is adapted to the connecting shaft 42.

[0046] In a further embodiment, the lengths of the connecting groove 44 and the connecting shaft 42 are less than the length of the connecting block. The extension lines of the connecting shaft 42 and the combined groove 41 intersect in space at an angle of 90 degrees. The distance between the combined block 43 and the central rod 14 is equal to the distance between the combined groove 41 and the central rod 14. The support block 11 is divided into a connecting block and a splitting block. Both the connecting block and the splitting block have slidably arranged contact blocks 13 and rotatably arranged rotating blocks 12. That is, the support block 11 is divided into two groups, with each group contacting one side of the user's thigh or calf. The connecting block and the splitting block can be connected to the connecting shaft 42 and the connecting groove 44 in two ways through the combined block 43 and the combined groove 41. Thus, the connecting block and the splitting block can be arranged vertically or horizontally symmetrically, and the contact blocks 13 can contact both sides of the thigh / calf or both sides of the ankle.

[0047] In some specific implementations, four sealing rods 51 are rotatably connected to the surface of the support block 11. Each sealing rod 51 and the support block 11 is fixedly connected to a ring spring 52. Two sealing rods 51 form a group, and the sealing rods 51 in the same group are symmetrically arranged relative to the central rod 14. When the rotating block 12 is not rotated and unfolded, the sealing rods 51 will block the area inside the support block 11, thereby avoiding obvious gaps on the surface of the support block 11 and the accumulation of dust that would affect the subsequent rotation of the rotating block 12.

[0048] The working principle of this utility model:

[0049] When using in a side-lying position, assemble the connecting block and the splitting block through the contact between the connecting block and the connecting groove 44. The connecting block and the splitting block are vertically symmetrical. Rotate the operating lever 32 to make the adjusting block 31 slide, which in turn drives the contact block 13 to slide. After the contact block 13 slides to the appropriate position, open the air plug 23 to inflate the air groove 21. After inflation, reset the air plug 23. Place the connecting block and the splitting block between the thighs, and then slide the rotating block 12 to make the protruding shaft 16 and the embedded shaft 17 separate. Rotate the rotating block 12 to make the rotating block 12 parallel to the lower leg. Release the rotating block 12, and the protruding shaft 16 contacts the embedded shaft 17, restricting the position of the rotating block 12. Adjust the contact block 13 inside the rotating block 12 in the same way to make the contact block 13 contact the lower leg.

[0050] When using it while lying down, assemble the connecting block and the splitting block through the combination block 43 and the combination slot 41, and change the position of the contact block 13 in the same way so that the contact block 13 contacts the two ankles.

[0051] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
