[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1-7 The utility model provides an embodiment of a segmented lower limb lifting and detumescence device, including a base frame 1, a connecting rod 3 is rotatably connected to a rotating plate 9 at the top relative to one end, the right end of the rotating plate 9 is rotatably connected to the right side of the top of the base frame 1, and a hollow slot plate 7 is rotatably connected to the right inner wall of the rear end of the rotating plate 9. A special-shaped slot 16 is provided at the front end of the rotating plate 9 corresponding to the right side of the hollow slot plate 7. Silicone pads 11 are fixed to the top of the hollow slot plate 7 and the rotating plate 9. Adhesive pads 10 are fixed to the top of the silicone pads 11. Replacement pads 8 are installed on the top of the adhesive pads 10. Through the cooperation of the fur-surface Velcro at the bottom of the replacement pad 8 and the thorn-surface Velcro at the top of the adhesive pad 10, after use by the patient, the medical staff only needs to tear off the replacement pad 8 and replace it.

[0036] The threaded rod 5 rotatably connected to the inner wall of the left end of the base frame 1 and the cross block 2 slidably connected to the inner walls at the front and rear ends of the base frame 1, the right end of the threaded rod 5 penetrates the outer wall of the base frame 1 and is rotatably connected to the right inner wall of the base frame 1, the right side of the outer wall of the threaded rod 5 is threadedly connected to the inner wall of the cross block 2, and the lower side of the opposite end of the connecting rod 3 is rotatably connected to the front and rear ends of the cross block 2. The medical staff rotates the handle on one side of the threaded rod 5 to cause the threaded rod 5 to rotate, so that the cross block 2 can slide on the inner walls on both sides of the base frame 1, thereby driving the angle between the bottom of the connecting rod 3 and the horizontal position of the base frame 1 to change and causing the top of the connecting rod 3 to drive one side of the rotating plate 9 to lift up, so that the angle between it and the base frame 1 changes, and then according to the angle that the patient's legs can be lifted, the rotating plate 9 is adjusted to a suitable inclined position.

[0037] The slider 18 is slidably connected to the inner wall of the right side of the front end of the hollow slot plate 7, and the front end of the slider 18 is fixedly connected to a toothed block 12. The shape of the outer wall of the toothed block 12 matches the shape of the inner wall of the special-shaped groove 16. The slider 18 is connected to the inner wall of the hollow slot plate 7 by a second spring 19. One end of the second spring 19 is fixedly connected to the rear end of the slider 18, and the other end of the second spring 19 is fixedly connected to the inner wall of the hollow slot plate 7. The toothed block 12 is pressed into the hollow slot plate 7 so that the slider 18 squeezes the spring. When the toothed block 12 is disengaged from the special-shaped groove 16, the limit between the hollow slot plate 7 and the rotating plate 9 is released. Then, the angle of the hollow slot plate 7 rotating downward is adjusted according to the bending amplitude of the patient's calf, and then the toothed block 12 is relaxed and driven to pop out and get into the special-shaped groove 16 under the elastic force of the second spring 19. The angle of the hollow slot plate 7 after rotation is limited by the engagement of the outer teeth of the toothed block 12 with the teeth of the inner wall of the special-shaped groove 16.

[0038] The adapter block 6 rotatably connected to the left side of the front and rear ends of the rotating plate 9 and the fixed plate 13 located at the front end of the base frame 1 and fixedly connected to the right side of the adapter block 6, the top and right ends of the front adapter block 6 are both provided with limiting holes 17, and the inner wall of the fixed plate 13 is slidably connected with a latch 15, and the shape of the left end of the latch 15 matches the shape of the inner wall of the limiting hole 17, and the latch 15 is connected to the fixed plate 13 through a first spring 14, one end of the first spring 14 is fixedly connected to the right end of the fixed plate 13, and the other end of the first spring 14 is fixedly connected to the inner wall of the right end of the latch 15. The right end of the concave support frame 4 is fixedly connected to the left ends of the front and rear adapter blocks 6 respectively. Then the patient places the leg that needs to reduce swelling on the replacement pad 8, pulls the pin 15 to disengage one end of it from the limiting hole 17, and at the same time the first spring 14 is stretched. Then the adapter block 6 is rotated to place the concave support frame 4 vertically on both sides of the rotating plate 9, and then the pin 15 is loosened to insert it into the limiting hole 17 after the upper position is rotated. The upright state of the concave support frame 4 is limited, and the quilt covering the patient's legs can be supported to prevent the quilt from sticking to the patient's skin.

[0039] Working principle: First, the medical staff rotates the handle on one side of the threaded rod 5 to cause the threaded rod 5 to rotate, so that the cross block 2 slides on the inner walls on both sides of the base frame 1, thereby driving the angle between the bottom of the connecting rod 3 and the horizontal level of the base frame 1 to change and causing the top of the connecting rod 3 to drive one side of the rotating plate 9 to lift up, so that the angle between it and the base frame 1 changes, and then according to the angle that the patient's legs can be lifted, the rotating plate 9 is adjusted to a suitable inclined position, and then the tooth block 12 is pressed into the empty slot plate 7 so that the slider 18 squeezes the spring. When the tooth block 12 is disengaged from the special-shaped groove 16, the limit between the empty slot plate 7 and the rotating plate 9 is released, and then the downward rotation angle of the empty slot plate 7 is adjusted according to the bending amplitude of the patient's calf, and then the tooth block 12 is released and driven to pop out of the card under the elastic force of the second spring 19. The patient then places the leg that needs to reduce swelling on the replacement pad 8, pulls the latch 15 to disengage one end of it from the limiting hole 17, and at the same time, the first spring 14 is stretched. The adapter block 6 is then rotated to place the concave support frame 4 vertically on both sides of the rotating plate 9, and the latch 15 is then released to insert it into the limiting hole 17 after the upper position is rotated. The upright state of the concave support frame 4 is limited, and the quilt covering the patient's legs can be supported to prevent the quilt from sticking to the patient's skin. The fleece Velcro at the bottom of the replacement pad 8 and the thorny Velcro at the top of the adhesive pad 10 cooperate to allow the medical staff to tear off the replacement pad 8 and replace it after use.
