Description

Technical Field

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

[0002] Leg support braces, as an important orthopedic assistive medical device, play a crucial role in the field of medical rehabilitation. They are primarily designed for the care and rehabilitation of the lower limbs, especially for patients who require leg immobilization and support due to fractures, surgery, or other reasons.

[0003] Most existing leg support systems use a lifting rod for elevation, but this common system has the following problems: 1. When a patient is lying in bed with their legs elevated, the angle between the leg and the support often differs, making it difficult for the leg to fully contact the bandage or support. This increases the risk of the leg falling and causes discomfort. 2. It's inconvenient to adjust and fix the support position according to the patient's leg position, requiring the patient to move their body to place their leg on the support, a process that causes significant discomfort. Therefore, a new leg support system is urgently needed to solve these problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a leg care bracket to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a leg care support, comprising:

[0006] A telescopic support frame is provided, with lockable casters installed at the four corners of the bottom end of the telescopic support frame. A slider is slidably fitted in the middle of the top end of the telescopic support frame, and a connecting plate is fixed on the top surface of the slider. Connecting rods are rotatably inserted at both ends of the connecting plate. A pad is fixed between the two sets of connecting rods. Toothed grooves are provided at both ends of the connecting plate, and a limiting cylinder is slidably inserted inside the toothed grooves. A tightening nut is threaded onto one end of the connecting rod.

[0007] A slot is provided on one side of the top center of the telescopic support frame. Both ends of one side of the slider are slidably inserted with bolts, and one end of the bolt is fixed with a plug. A spring is slidably sleeved on the outer surface of one end of the bolt.

[0008] Preferably, the surface of the pad is covered with a sponge pad, and the pad is designed to be arc-shaped to make it more comfortable for the patient to place their legs.

[0009] Preferably, one end of the connecting rod extends to the outside of the connecting plate and is gear-shaped, one end of the connecting rod is screw-shaped, and the other end of the connecting rod is smooth rod-shaped. The other end of the connecting rod passes through the connecting plate and is fixedly connected to the pad. The center of the connecting rod and the center of the tooth groove are on the same horizontal plane, which facilitates the angle adjustment of the pad.

[0010] Preferably, the inner wall of the limiting cylinder is provided with a toothed groove that matches the gear-shaped end of the connecting rod. The limiting cylinder is slidably sleeved on the outer surface of the connecting rod. One end of the outer wall of the limiting cylinder is set as a square gear shape that matches the toothed groove. The square gear-shaped end of the limiting cylinder is slidably inserted into the toothed groove to facilitate fixing the angle of the pad.

[0011] Preferably, the tightening nut is threaded onto one end of the connecting rod, and one side of the tightening nut is attached to but not fixed to one side of the limiting cylinder, so that the limiting cylinder will not easily slip out.

[0012] Preferably, multiple sets of slots are provided, and the multiple sets of slots are distributed equidistantly in a linear array on one side of the top center of the telescopic support frame. One end of the insert block passes through the slider and is slidably inserted into the slot. The two are tightly attached to each other without gaps, which facilitates limiting and fixing the slider at multiple positions.

[0013] Preferably, one end of the spring is fixedly connected to the inner wall of the slider, and the other end of the spring is fixedly connected to one side of the insert block, so that the insert block can maintain its position inside the slot.

[0014] The technical effects and advantages of this utility model are as follows: This utility model uses a connecting plate, pad, connecting rod, toothed groove, limiting cylinder and tightening nut in cooperation. The tilt angle of the pad can be adjusted according to the angle of the patient's leg after it is raised, so that the angles of the two are matched. This makes the patient's leg fit the pad better, which can reduce the foreign body sensation of the patient's leg and enhance the patient's comfort. The tight fit can also increase the friction between the pad and the patient's leg, thereby reducing the risk of the patient's leg falling off. The device is safer and more comfortable to use.

[0015] The device utilizes a telescopic support frame, lockable casters, sliders, bolts, springs, inserts, and slots in combination to allow for adjustable slider positions. This makes it easy to adjust the position of the pad according to the specific position of the patient's legs, eliminating the need for the patient to move their body frequently, reducing discomfort and pain, and making the device more flexible and adaptable.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, this embodiment proposes a leg care support, including a telescopic support frame 1. Lockable casters 2 are installed at the four corners of the bottom of the telescopic support frame 1. A slider 3 is slidably fitted at the center of the top of the telescopic support frame 1, and a connecting plate 4 is fixed to the top surface of the slider 3. Connecting rods 6 are rotatably inserted into both ends of the connecting plate 4. A pad 5 is fixed between the two sets of connecting rods 6. Toothed grooves 7 are formed at both ends of the connecting plate 4, and limiting cylinders 8 are slidably inserted inside the toothed grooves 7. A tightening nut 9 is threaded onto one end of the connecting rod 6. The surface of the pad 5 is covered with a sponge pad, and the pad 5 is arc-shaped. One end of the connecting rod 6 extends to the outside of the connecting plate 4 and is gear-shaped. One end of the connecting rod 6 is set as a screw, and the other end of the connecting rod 6 is set as a smooth rod. The other end of the connecting rod 6 passes through the connecting plate 4 and is fixedly connected to the pad 5. The center of the connecting rod 6 and the center of the tooth groove 7 are on the same horizontal plane. The inner wall of the limiting cylinder 8 is provided with a toothed groove that matches the gear-shaped end of the connecting rod 6. The limiting cylinder 8 is slidably sleeved on the outer surface of the connecting rod 6. One end of the outer wall of the limiting cylinder 8 is set as a square gear that matches the tooth groove 7. The square gear-shaped end of the limiting cylinder 8 is slidably inserted into the tooth groove 7. The tightening nut 9 is threadedly sleeved on the screw-shaped end of the connecting rod 6. One side of the tightening nut 9 is in contact with one side of the limiting cylinder 8 but is not fixed.

[0024] In this embodiment, when the angle of the pad 5 needs to be adjusted, the two sets of clamping nuts 9 are first rotated clockwise to disengage them from the screw-shaped end of the connecting rod 6. Then, the limiting cylinder 8 is pulled out from inside the toothed groove 7, and the limiting cylinder 8 slides along the outer surface of the connecting rod 6. After that, the pad 5 is rotated to a suitable angle, which is consistent with the angle formed after the patient's leg is raised. The pad 5 drives the connecting rod 6 to rotate synchronously. Then, one end of the limiting cylinder 8 is slid into the toothed groove 7, and the limiting cylinder 8 is sleeved on the outer surface of the connecting rod 6. The limiting cylinder 8 cannot rotate under the limitation of the toothed groove 7, and the connecting rod 6 cannot rotate under the limitation of the limiting cylinder 8, thus fixing the angle of the pad 5. Finally, the clamping nut 9 is rotated counterclockwise and sleeved on the outer surface of the screw-shaped end of the connecting rod 6, so that one side of the clamping nut 9 is in contact with one end of the limiting cylinder 8 to prevent the limiting cylinder 8 from sliding out of the toothed groove 7.

[0025] Example 2

[0026] like Figure 1 and Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: a slot 13 is provided on one side of the top middle of the telescopic support frame 1, and a pull bolt 10 is slidably inserted into both ends of one side of the slider 3, and a plug 12 is fixed to one end of the pull bolt 10. A spring 11 is slidably sleeved on the outer surface of one end of the pull bolt 10. Multiple sets of slots 13 are provided, and multiple sets of slots 13 are equidistantly distributed in a linear array on one side of the top middle of the telescopic support frame 1. One end of the plug 12 passes through the slider 3 and is slidably inserted into the slot 13. The two are tightly attached to each other without gaps. One end of the spring 11 is fixedly connected to the inner wall of the slider 3, and the other end of the spring 11 is fixedly connected to one side of the plug 12.

[0027] In this embodiment, when adjusting the specific position of the pad 5, the telescopic support frame 1 can first be moved to a suitable position by relying on the lockable caster 2 and the lockable caster 2 can be locked. Then, pull the two sets of bolts 10 so that the insert 12 slides out completely from the slot 13. The insert 12 retracts into the slider 3 and squeezes the spring 11. Then, slide the slider 3 along the outer surface of the middle of the telescopic support frame 1 so that the slider 3 drives the connecting plate 4 and the pad 5 to the position corresponding to the patient's leg. Then, release the bolts 10. Under the rebound of the spring 11, the spring 11 pushes the insert 12 into the corresponding set of slots 13 to fix the position of the slider 3.

[0028] Working principle: First, move the telescopic support frame 1 to a suitable position. Then, slide the slider 3 to the position corresponding to the patient's leg and use the insert block 12 to fix the position of the slider 3 in the slot 13. After that, remove the clamping nut 9 and the limiting cylinder 8 from the connecting rod 6. Then, have the patient place their leg on the surface of the pad 5. Adjust the height of the telescopic support frame 1 according to the desired height. The telescopic support frame 1 can use a suitable lifting rod available on the market. This is existing technology, and users can choose to use it themselves. It will not be elaborated on here. As the height of the middle part of the telescopic support frame 1 increases, the pad 5 also rises synchronously. As the patient's leg rises, it will press against the pad 5 and rotate. The pad 5 drives the connecting rod 6 to rotate synchronously. After the height is reached, the doctor can also manually adjust the tilt angle of the pad 5 to match the angle of the patient's leg after it is raised. Finally, use the limiting cylinder 8 and the clamping nut 9 to fix the angle of the pad 5. The above is the complete working principle of this utility model.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
