[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a straight leg raising auxiliary sling.

[0028] like Figure 1-4 As shown, this utility model discloses a straight leg raise assistive sling, comprising a sliding sleeve 1 and a leg support belt 4. Both ends of the leg support belt 4 are connected to adjustable straps 5, each including a first connecting strap 8 and a second connecting strap 9. The first connecting strap 8 has multiple equally spaced through holes 10 arranged vertically along its central portion. The bottom surface of the second connecting strap 9 has two vertically distributed studs 11, each passing through one of the through holes 10 and threadedly connected to a knob. Through the interaction between the studs 11 and the through holes 10, the length of the adjustable strap 5 can be flexibly adjusted, facilitating use for different patients and providing greater convenience and comfort. For shorter patients, the length of the adjustable strap 5 can be increased; for taller patients, it can be decreased. Pull ropes 6 are connected to the top ends of both adjustable straps 5. The bottom of the first connecting strap 8 is fixedly connected to the leg support belt 4, and the top end of the second connecting strap 9 is fixedly connected to the pull rope 6.

[0029] The bottom of the sliding sleeve 1 is provided with a base plate 2, and the bottom of the base plate 2 is provided with two symmetrically distributed pulleys 3. The ends of the two pull ropes 6 pass over the two pulleys 3 respectively and are connected to a fixing plate 7. The surface of the fixing plate 7 is provided with a grip bar 23, and the fixing plate 7 is provided with a fixing structure for fixing the wrist. The fixing structure includes an elastic band 24 and a hanging post 26. One end of the elastic band 24 is fixedly connected to one side wall of the fixing plate 7, and the other end is provided with a hanging hole 25. One end of the hanging post 26 is fixed to the other side wall of the fixing plate 7. The other end of the hanging post 26 is equipped with a limiting ball head 27. The limiting ball head 27 can effectively prevent the hanging hole 25 from coming loose from the hanging post 26. When the patient holds the grip bar 23, the elastic band 24 is wrapped around the patient's wrist and the hanging hole 25 is hung on the hanging post 26 to fix the elastic band 24. This fixes the elastic band 24 to the patient's wrist and can effectively prevent the patient's hand from coming loose from the grip bar 23, which could cause the leg to suddenly fall and cause secondary injury. It is highly safe.

[0030] The sliding sleeve 1 includes an upper ring 12 and a lower ring 13, which are rotatably connected by a pivot and fixedly connected by a locking structure. The locking structure includes a lower connecting block 16 and an upper connecting block 20. The upper surface of the lower connecting block 16 is provided with a socket 17, and the bottom of the upper connecting block 20 is provided with inserts 21 corresponding to the socket 17. The size of the inserts 21 matches the size of the socket 17. The side wall of the lower connecting block 16 is provided with a first through hole 18 penetrating the socket 17, and the side wall of the inserts 21 is provided with a second through hole corresponding to the first through hole 18. A rod 19 is inserted between the first perforation 18 and the second perforation 22. In use, the upper ring 12 and lower ring 13 are first opened, then wrapped around the crossbar on the bed. The upper ring 12 and lower ring 13 are then closed, at which point the insert block 21 will be inserted into the insertion port 17. The rod 19 is then inserted into the first perforation 18 and the second perforation 22, thus fixing the upper ring 12 and lower ring 13 together. The sliding sleeve 1 can then slide on the crossbar to adjust the position of the leg support belt 4 according to the patient's position. After adjusting the position, the sliding sleeve 1 is locked in place by tightening the locking bolt 15. A pull ring is provided at the end of the rod 19 for easy pulling. A threaded block 14 is provided in the middle of the upper surface of the upper ring 12. A locking bolt 15 is internally threaded into the threaded block 14, and the bottom of the locking bolt 15 extends to the bottom of the upper ring 12.

[0031] The working principle of this straight leg raise assistive sling is as follows: First, open the upper ring 12 and lower ring 13, then wrap them around the crossbar on the bed. Next, merge the upper ring 12 and lower ring 13 together. At this point, the insert block 21 will be inserted into the insert 17. Then, insert the insert rod 19 into the first through hole 18 and the second through hole 22 to fix the upper ring 12 and lower ring 13 together. The sliding sleeve 1 can then slide on the crossbar to adjust the position of the leg raise sling 4 according to the patient's position. After adjusting the position, tighten the locking bolt 15 to lock and fix the sliding sleeve 1. Then, place the patient's leg on the leg raise sling 4, and hold the handle 23 with the hand. Wrap the elastic band 24 around the patient's wrist and hang it on the hanging post 26 through the hanging hole 25 to fix the elastic band 24. This allows the elastic band 24 to be fixed to the patient's wrist. By adjusting the length of the adjusting band 5, the patient can pull their legs more comfortably. Finally, by pulling the grip bar 23, the pull rope 6 moves the leg suspension band 4 upward, allowing the patient's legs to lift. This exercises the legs and also the patient's upper limbs, helping to address the lack of lower limb care for paralyzed patients, long-term bedridden patients, patients with low limb movement deficiency, and patients with lower limb movement disorders. It promotes upper limb and lung function, promotes gastrointestinal motility, effectively prevents constipation, promotes wound healing, prevents lower limb muscle stiffness and atrophy, avoids venous thrombosis or bedsores, and avoids nerve root adhesions, thereby effectively restoring the patient's lower limb strength and promoting medical rehabilitation.
