Abstract
Description
Technical Field
[0001] This utility model relates to the field of knee brace technology, and in particular to a knee brace structure suitable for patients with rheumatic bone diseases. Background Technology
[0002] Knee braces are widely used in modern medicine and sports medicine, especially in the prevention and treatment of knee-related diseases. With increasing emphasis on sports and health, knee braces are constantly being innovated in design and materials. Today's knee braces not only provide support but also have multiple functions such as warmth, shock absorption, and pain relief. By using breathable materials and ergonomic design, modern knee braces can provide better protection for athletes and the general public, reducing the risk of sports injuries. Combined with smart technology, some knee braces have functions such as temperature regulation and pressure feedback, providing patients with a more precise nursing experience.
[0003] In general, knee braces, especially for patients with rheumatic bone diseases, can be problematic. Their knees cannot be exposed to cold and wind, and wearing knee braces often causes local temperature changes, potentially leading to discomfort. Knee movement can cause friction between the brace and the patella, causing the applied medicated plaster to fall off. Frequent plaster changes not only increase the burden on the patient but may also lead to insufficient medication efficacy and worsen the condition. Furthermore, during daily activities, knee braces may not effectively hold the medication in place, affecting the overall rehabilitation effect and failing to meet actual needs. Utility Model Content
[0004] This utility model discloses a knee brace structure suitable for patients with rheumatic bone diseases. It aims to address the technical problems encountered with conventional knee braces, particularly for patients with rheumatic bone diseases. These patients' knees cannot be exposed to cold and wind, and wearing knee braces often leads to local temperature changes, potentially causing discomfort. Knee movement causes friction between the knee brace and the patella, leading to the attachment of therapeutic plasters falling off. Frequent plaster replacements not only increase the burden on patients but may also result in insufficient medication efficacy, worsening the condition. Furthermore, the use of knee braces during daily activities may not effectively secure therapeutic medications, affecting the overall rehabilitation outcome.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A knee brace structure suitable for patients with rheumatic bone diseases includes an outer shell. A first rotating cover and a second rotating cover are rotatably connected to the inner walls of both sides of the outer shell. An insertion hole is provided on one edge of the first rotating cover, and an insertion rod is slidably connected to one side of the second rotating cover. A movable strip is fixedly connected to the outer wall of the insertion rod. Connecting rings are fixedly connected to the four corners of the bottom of the outer shell. A fixing strap is fixedly connected to the bottom of one connecting ring, and two connecting grooves are provided at the bottom of the other connecting ring. The other end of the fixing strap passes through the connecting groove. A first elastic rope and a second elastic rope are fixedly connected to the inner wall of the other side of the outer shell. A first medicated band is fixedly connected to the bottom of the first elastic rope, and a second medicated band is fixedly connected to the bottom of the second elastic rope. Multiple sweat-permeable holes are provided on the upper surfaces of the second and first medicated bands. A Velcro fastener is provided at one end of the fixing strap. Torsion springs are provided at the connection points between the first and second rotating covers and the outer shell.
[0007] The Velcro strap consists of a male and a female tab, which connects one end of the fixing strap to the connecting ring.
[0008] In a preferred embodiment, a rotating ball is provided on one side of the first rotating cover, and a sliding rod is slidably connected to the bottom of the rotating ball.
[0009] The bottom end of the sliding rod is movably connected to a contact plate, and a buffer spring is sleeved on one end of the sliding rod near the contact plate.
[0010] The tops of the first rotating cover and the second rotating cover are respectively fixedly connected with protective shells.
[0011] Flexible pads are fixedly connected to the bottom of the first rotating cover and the second rotating cover, respectively.
[0012] Multiple ventilation holes are provided at both ends of the outer shell.
[0013] As can be seen from the above, the knee brace structure for patients with rheumatic bone diseases provided by this utility model has the following technical effects.
[0014] Firstly, the first and second medicated bands come into contact with the knee. By pulling the first and second elastic ropes, the first and second medicated bands are separated from the skin of the knee. The plaster is then applied to the knee. The first and second elastic ropes are released, allowing the first and second medicated bands to re-attach to the knee. The plaster is then squeezed to ensure stable contact with the knee. The first and second rotating covers are rotated, and the movable strip is inserted into the insert rod to fix the first and second rotating covers in place. Because the knee is frequently in motion, the plaster often falls off and needs to be reapplied. There is no need to remove the outer shell; it can be opened directly by rotating the first and second rotating covers, making it convenient to reapply the plaster. This achieves the effect of keeping the knee warm while conveniently applying medicine to the knee of patients with rheumatic bone diseases.
[0015] Secondly, because the patella changes position significantly during knee movement, the contact disc compresses the patella, and the compression spring causes the sliding rod and rotating ball to slide relative to each other. During knee movement, the patella changes position, and the design of the rotating ball, sliding rod, and buffer spring ensures that the contact disc remains in contact with the patella, keeping the first and second elastic ropes in close contact with the knee, thus reducing the risk of the plaster falling off.

[0023] This utility model discloses a knee brace structure suitable for patients with rheumatic bone diseases. It addresses the common issues with general knee braces, particularly for patients with rheumatic bone diseases. These patients' knees cannot be exposed to cold and wind, and wearing a knee brace often causes local temperature changes, potentially leading to discomfort. Knee movement can cause friction between the knee brace and the patella, causing the applied therapeutic plaster to fall off. Frequent plaster replacements not only increase the patient's burden but may also lead to insufficient medication efficacy and worsen the condition. Furthermore, the knee brace may not effectively secure the medication during daily activities, affecting the overall recovery outcome.
[0024] Reference Figure 1 — Figure 4 A knee brace structure suitable for patients with rheumatic bone diseases includes an outer shell 1. A first rotating cover 2 and a second rotating cover 10 are rotatably connected to the inner walls of both sides of the outer shell 1. An insertion hole 5 is provided on one edge of the first rotating cover 2. An insertion rod 8 is slidably connected to one side of the second rotating cover 10. A movable strip 9 is fixedly connected to the outer wall of the insertion rod 8. Connecting rings 11 are fixedly connected to the four corners of the bottom of the outer shell 1. A fixing strap 12 is fixedly connected to the bottom of one connecting ring 11. Two connecting grooves are provided at the bottom of the other connecting ring 11. The other end of the fixing strap 12 passes through the connecting groove. A first elastic rope 15 and a second elastic rope 16 are fixedly connected to the inner wall of the other side of the outer shell 1. A first medicated band 6 is fixedly connected to the bottom of the first elastic rope 15. A second medicated band 7 is fixedly connected to the bottom of the second elastic rope 16. Multiple sweat-permeable holes 17 are provided on the upper surfaces of the second medicated band 7 and the first medicated band 6. A Velcro is provided at one end of the fixing strap 12. Torsion springs 14 are provided at the connection points between the first rotating cover 2, the second rotating cover 10 and the outer shell 1.
[0025] The Velcro straps are divided into male and female straps, which connect one end of the fixing strap 12 to the connecting ring 11.
[0026] In this embodiment, the knees of patients with rheumatic bone disease should not be exposed to cold. The outer shell 1 is placed on the patient's knee using the fixing strap 12. The ointment for treating rheumatic bone disease is applied to the patient. During the application of the ointment to the knee, the movable strip 9 is moved so that the insert 8 slides out from the inside of the insertion hole 5. This causes the torsion spring 14 to drive the first rotating cover 2 and the second rotating cover 10 to rotate, thereby exposing the first medicated band 6 and the second medicated band 7.
[0027] Furthermore, the first medicated band 6 and the second medicated band 7 come into contact with the knee. By pulling the first elastic rope 15 and the second elastic rope 16, the first medicated band 6 and the second medicated band 7 are separated from the skin of the knee. The plaster is then applied to the knee. The first elastic rope 15 and the second elastic rope 16 are released, allowing the first medicated band 6 and the second medicated band 7 to reattach to the knee. The plaster is then squeezed to ensure stable contact between the plaster and the knee. The first rotating cover 2 and the second rotating cover 10 are rotated, and the movable strip 9 is inserted into the insert 8 to fix the first rotating cover 2 and the second rotating cover 10 in place. Because the knee is frequently moved, the plaster often falls off and needs to be reapplied. There is no need to remove the outer shell 1; the plaster can be opened directly by rotating the first rotating cover 2 and the second rotating cover 10, making it convenient to reapply the plaster. This achieves the effect of keeping the knee warm while conveniently applying medicine to the knee of patients with rheumatic bone diseases.
[0028] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, a rotating ball 18 is provided on one side of the first rotating cover 2, and a sliding rod 19 is slidably connected to the bottom of the rotating ball 18.
[0029] The bottom end of the sliding rod 19 is movably connected to the contact plate 21, and a buffer spring 20 is sleeved on one end of the sliding rod 19 near the contact plate 21.
[0030] Protective shells 4 are fixedly connected to the top of the first rotating cover 2 and the second rotating cover 10, respectively.
[0031] Flexible pads 3 are fixedly connected to the bottom of the first rotating cover 2 and the second rotating cover 10, respectively.
[0032] Multiple ventilation holes 13 are provided at both ends of the outer shell 1.
[0033] In this embodiment, since the patella position changes significantly during knee movement, the contact disc 21 compresses the patient's patella, and the compression buffer spring 20 causes the sliding rod 19 and the rotating ball 18 to slide relative to each other. During knee movement, the patella position changes, and through the design of the rotating ball 18, the sliding rod 19 and the buffer spring 20, the contact disc 21 always remains in contact with the patella, and the first elastic rope 15 and the second elastic rope 16 always adhere to the knee, which reduces the effect of plaster falling off.
[0034] Working Principle: During use, the knees of patients with rheumatism and bone disease should not be exposed to cold. Using the fixing strap 12, the outer shell 1 is placed on the patient's knee. The plaster for treating rheumatism and bone disease is applied. While applying the plaster to the knee, the movable strip 9 is moved, causing the insert 8 to slide out from the insertion hole 5. This causes the torsion spring 14 to rotate the first rotating cover 2 and the second rotating cover 10, exposing the first medicated band 6 and the second medicated band 7. The first medicated band 6 and the second medicated band 7 come into contact with the knee. By pulling the first elastic rope 15 and the second elastic rope 16, the first medicated band 6 and the second medicated band 7 are separated from the skin of the knee, allowing the plaster to be applied to the knee. The first elastic rope 15 and the second elastic rope 16 are then released, allowing the first medicated band 6 and the second medicated band 7 to re-attach to the knee. Squeezing the plaster ensures stable contact between the plaster and the knee. The first rotating spring 14 then rotates the second rotating cover 10. The movable cover 2 and the second rotating cover 10 are fixed in place by inserting the movable strip 9 into the insert rod 8. Due to frequent knee movements, the plaster often falls off and needs to be reapplied. There is no need to remove the outer shell 1; the plaster can be opened directly by rotating the first rotating cover 2 and the second rotating cover 10, making it convenient to reapply the plaster. This achieves the effect of keeping the knee warm while conveniently applying the plaster to the knee of patients with rheumatic bone diseases. Because the position of the patella changes greatly during knee movement, the contact plate 21 presses the position of the patient's patella, and the compression buffer spring 20 drives the sliding rod 19 to slide relative to the rotating ball 18. During knee movement, the position of the patella changes. Through the design of the rotating ball 18, the sliding rod 19 and the buffer spring 20, the contact plate 21 always keeps in contact with the patella, and the first elastic rope 15 and the second elastic rope 16 always fit the knee, which reduces the effect of plaster falling off.
[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
