Description

Technical Field

[0001] This utility model relates to the field of leg support frame technology, specifically a leg support frame. Background Technology

[0002] In orthopedic nursing, proper leg support and care devices are crucial for patients with leg injuries or who have undergone surgery. Suitable leg supports not only help patients maintain correct leg posture, reduce pain, and promote blood circulation, but also provide a stable support environment for leg rehabilitation, effectively preventing secondary injuries caused by improper leg movement, thereby accelerating the recovery process.

[0003] Existing leg supports only provide basic leg support. However, different patients have different injuries, degrees of injury, and physical conditions, resulting in varying requirements for the height, angle, and comfort of leg support. Traditional supports cannot meet these diverse needs. During leg care, it is sometimes necessary to suspend the patient's leg to reduce leg pressure, promote blood circulation, or facilitate certain nursing procedures. Existing leg supports cannot achieve stable and comfortable leg suspension, causing great inconvenience to nursing work. Furthermore, existing leg supports usually support both legs simultaneously. When only one leg needs support, the device occupies a large space and is inconvenient to use. Therefore, we propose a new leg support. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This utility model provides a technical solution: a leg support frame, including a support base 1, two support bases 1 are symmetrically arranged, a vertical plate 2 is fixedly connected to the top of the support base 1, and a connecting plate 7 is connected to the top of the two vertical plates 2, a first linear module 3 is arranged inside the vertical plate 2, and a crossbar 4 is fixedly connected to the end of the lifting block of the first linear module 3, a second linear module 8 is arranged inside the crossbar 4, and a leg support mechanism 5 for supporting the patient's leg is arranged at the top of the sliding block of the second linear module 8, and a leg lifting mechanism 6 for suspending the patient's leg is symmetrically arranged at the bottom of the connecting plate 7, and the distance between the two vertical plates 2 at the bottom of the connecting plate 7 is adjustable.

[0024] Please see Figure 2 The leg lifting mechanism 6 includes a fixed plate 9. The top of the sliding block of the second linear module 8 is fixedly connected to the fixed plate 9. The two ends of the fixed plate 9 are symmetrically provided with sliding holes, and the sliding holes are fitted with support rods 11. The top of the two support rods 11 is fixedly connected to the leg support plate 10, and the bottom ends of the two support rods 11 are threaded with nuts. The outside of the support rods 11 is fitted with a first spring 12 between the leg support plate 10 and the fixed plate 9.

[0025] It should be noted that the sliding holes symmetrically opened at both ends of the fixing plate 9 are slidably connected with the support rod 11, so that the leg support plate 10 can only move up and down in a straight line along the axial direction of the support rod 11, which restricts its swaying in other directions. During the leg lifting process, the leg support plate 10 can be stably moved, avoiding the insecurity caused to the patient by swaying. At the same time, it is also convenient for medical staff to accurately control the position and height of the leg lifting.

[0026] Please see Figure 1 and Figure 3The leg lifting mechanism 6 includes a support cylinder 13. The top of the connecting plate 7 has symmetrical through holes, and the support cylinder 13 is rotatably connected to the through holes through bearings. The support cylinder 13 is threaded with a lifting rod 14. The bottom of the lifting rod 14 is fixedly connected to a limit plate 19, and the bottom of the limit plate 19 is symmetrically fixedly connected to a sliding rod 21. The ends of the two sliding rods 21 are connected to mounting blocks 20. The two ends of the mounting blocks 20 have symmetrical lifting holes. The ends of the two sliding rods 21 slide through the lifting holes, and the bottom ends of the two sliding rods 21 are threadedly connected to nuts. A second spring 22 is sleeved on the outside of the sliding rod 21 between the limit plate 19 and the mounting block 20. The bottom end of one side of the mounting block 20 is fixedly connected to a first connecting band 23, and the bottom end of the other side of the mounting block 20 is fixedly connected to a second connecting band 24. The first connecting band 23 and the second connecting band 24 are fixedly connected.

[0027] It should be noted that when using this utility model, the device is installed on the hospital bed. During installation, the installation position is selected according to the patient's height. Then, the two upright plates 2 are slidably adjusted to the two ends of the connecting plate 7. The two sides of the two bed boards are respectively clamped between the positioning plate 27 in the two support seats 1 and the top of the inner wall of the support seat 1. Then, the adjusting bolts 28 are adjusted to clamp the bed boards in the support seats 1. Then, the nuts at both ends of the connecting bolt rod 26 are connected to fix the relative position of the upright plates 2 and the connecting plate 7. The height of the leg support mechanism 5 and the distance between the two leg support mechanisms 5 can be adjusted according to the patient's condition. The height of the leg support mechanism 5 can be adjusted through the first linear module 3, and the position of the leg support mechanism 5 on the crossbar 4 can be adjusted through the second linear module 8, thereby adjusting the distance between the two leg support mechanisms 5 to suit the patient's optimal comfort. The patient's legs are supported in the arc groove on the leg support plate 10, and the first spring 12 plays a buffering role to ensure comfort during placement.

[0028] When nursing care is needed, adjust the leg lifting mechanism 6 to the position of the patient's leg, fix the patient's leg through the first connecting belt 23 and the second connecting belt 24, and then turn the rotating handle 18 to drive the worm gear 17 to rotate. The meshing of the worm gear 17 and the worm wheel 15 causes the support cylinder 13 to rotate. The threaded connection between the lifting rod 14 and the support cylinder 13 raises the fixed leg position, allowing the patient's leg to be suspended in the air for easy nursing care.

[0029] When not in use, the bolt rod 26 can be removed, so that both upright plates 2 are disconnected from the connecting plate 7, allowing the leg support mechanism 5 on each support seat 1 to be used independently to support a patient with an injured leg, making it more flexible in use.

[0030] Please see Figure 3The first connecting strip 23 has a Velcro-fitting surface at one end away from the mounting block 20, and the second connecting strip 24 has a Velcro-adhesive surface on one side of the first connecting strip 23. The first connecting strip 23 and the second connecting strip 24 are fixed together by Velcro. The top of the limiting plate 19 is symmetrically fixed with limiting rods, and the ends of the two limiting rods slide through the connecting plate 7.

[0031] It should be noted that the first connecting strap 23 and the second connecting strap 24 are fixed by Velcro, which is simple to operate and firmly fixed, and can be adapted to people with different leg shapes. Limiting rods are symmetrically fixed to the top of the limiting plate 19. During the lifting and lowering of the limiting plate 19, the limiting rods are slidably connected to the connecting plate 7, making the lifting rod 14 lift and lower more smoothly.

[0032] Please see Figure 1 The bottom of the support base 1 is provided with a threaded hole, and an adjusting bolt 28 is threadedly connected inside the threaded hole. One end of the adjusting bolt 28 located inside the support base 1 is rotatably connected to a positioning plate 27 via a bearing. The positioning plate 27 is slidably connected to the inner wall of the support base 1.

[0033] It should be noted that the adjusting bolt 28 can adjust the height of the positioning plate 27 inside the support base 1, which can stabilize the bed board between the top of the positioning plate 27 and the inner wall of the support base 1, thereby enhancing the overall stability of the device.

[0034] Please see Figure 4 Both ends of the connecting plate 7 are provided with horizontal moving grooves. The top of the vertical plate 2 is slidably connected in the moving groove. The connecting plate 7 is provided with a sliding groove 25 symmetrically at one end of the moving groove. The top of the vertical plate 2 is provided with a connecting hole, and a bolt rod 26 is provided in the connecting hole. The two ends of the bolt rod 26 are slidably connected in the two sliding grooves 25 respectively, and the two ends of the bolt rod 26 outside the connecting plate 7 are threaded with nuts.

[0035] It should be noted that the bolt rod 26 and the nuts at both ends can fix the upright plate 2 and the connecting plate 7. When the nuts are loosened, the upright plate 2 can slide in the moving groove on the connecting plate 7, thereby adjusting the distance between the two support seats 1 and facilitating the connection between the support seats 1 and the bed board of the hospital bed.

[0036] Please see Figure 1 The support base 1 has a vertical lifting groove on its outer side, and the positioning plate 27 has a lifting block integrally installed on its side wall, and the lifting block is slidably connected inside the lifting groove.

[0037] It should be noted that during the lifting and lowering process of the positioning plate 27, the lifting block on it is slidably connected inside the lifting groove, making the lifting and lowering of the positioning plate 27 more stable and better able to fix the device on the bed board.

[0038] Please see Figure 1 A worm gear 15 is fixedly connected to the outside of the support cylinder 13. A mounting plate 16 is symmetrically fixedly connected to the top of the connecting plate 7 on the outside of the support cylinder 13. A worm 17 is rotatably connected between the two mounting plates 16 through a bearing. The worm 17 and the worm gear 15 are meshed together. A rotating handle 18 is rotatably connected to the outside of the mounting plate 16 through a bearing. The central shaft end of the rotating handle 18 passes through the mounting plate 16 and is fixedly connected to the worm 17.

[0039] It should be noted that the rotation of the worm gear 17 can be controlled by rotating the rotary handle 18. The rotation of the support cylinder 13 can be achieved through the meshing connection between the worm gear 17 and the worm wheel 15. When the support cylinder 13 rotates, the lifting rod 14 is threadedly connected to it, thereby raising and lowering the lifting rod 14, which can adjust the height of the leg lifting mechanism 6.
