Description

Technical Field

[0001] The present invention relates to the technical field of foot orthopedics for arthritis, and particularly to a foot orthopedic and warming device for rheumatoid arthritis. Background Art

[0002] Arthritis is a common joint disease that often causes pain, swelling, and limited joint movement. Foot drop is one of the common symptoms in arthritis patients, manifested as the inability to normally lift the front part of the foot when walking, resulting in the toes drooping downward, which may cause falls and walking inconvenience. With the progress of medicine and rehabilitation technology, foot correction technology has been widely applied. Modern foot correction devices such as arch support insoles, orthopedic boots, and ankle braces can effectively assist in adjusting the foot posture.

[0003] Existing foot correction devices play an important role in the rehabilitation process, but there are still some limitations when in use. General devices can only rely on the patient to rotate the foot by themselves for correction and training, which limits the training effect. These devices cannot effectively reduce the burden on the patient's feet, resulting in easy fatigue and strain of the foot muscles during training. Prolonged use may cause discomfort and even aggravate the patient's condition, unable to meet the actual needs. Summary of the Invention

[0021] First: During the first upward movement of the patient's foot surface, the rotating plate drives the linkage plate to rotate up and down, causing the limiting rod to slide from the long groove into the short groove. The sliding rod squeezes the energy storage spring to form a downward thrust. Since the position of the limiting rod in the short groove is lower than that in the long groove, the sliding rod squeezes the energy storage spring to form a greater downward thrust. When the patient lifts the foot surface for the second time, the downward thrust of the energy storage spring drives one end of the linkage plate and the rotating plate to rotate downward, thereby helping the patient lift the foot surface. By storing energy in the energy storage spring, the burden on the foot surface muscles of the patient is reduced, achieving the effect of protecting the patient's joints.

[0022] Second: During the process of turning the foot surface left and right, by rotating the handle, the bidirectional threaded rod is driven to rotate, controlling the two pressing plates to approach or move away from each other, increasing or decreasing the elastic force inside the two load springs. When the rotating plate drives the flipping plate to flip through the connecting block, the buffer spring is driven by the insertion rod to squeeze the load springs on both sides, achieving the effect of controlling the resistance of the patient's flipping foot.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0035] A foot orthosis and warming device for rheumatoid arthritis disclosed by the present invention is mainly applied to scenarios where general devices can only rely on the patient to rotate the foot by themselves for correction and training, which limits the training effect. These devices cannot effectively reduce the burden on the patient's foot, resulting in easy fatigue and strain of the foot muscles during training. Prolonged use may cause discomfort and even aggravate the patient's condition.

[0036] Refer to Figure 1 — Figure 8, an orthopedic and warming device for the feet of rheumatoid arthritis, comprising a bottom plate 1, the bottom plate 1 is fixedly connected to a housing 10, one side of the bottom of the housing 10 is rotatably connected to a plug rod 18, one end of the plug rod 18 is fixedly connected to a turning plate 3, two connecting blocks 2 are arranged on the upper surface of the turning plate 3, the upper surface of the other end of the bottom plate 1 is fixedly connected to a front plate 4, the top of the front plate 4 is fixedly connected to a mounting bracket 7, a linkage plate 12 is rotatably connected to the upper surface of the turning plate 3, a rotating disc 24 is rotatably connected to the upper surface of the linkage plate 12, a rotating plate 11 is fixedly connected to the upper surface of the rotating disc 24, a first fixing belt 15 is arranged at one end of the upper surface of the rotating plate 11, a second fixing belt 17 is arranged at the other end of the upper surface of the rotating plate 11, a thermal insulation shoe cover 5 is arranged between the first fixing belt 15 and the second fixing belt 17, and an opening 29 is arranged at a position on one side of the housing 10 close to the linkage plate 12;

[0037] A power storage mechanism is installed inside the housing 10, and the power storage mechanism is used to reduce the burden on the foot surface muscles;

[0038] An adjusting mechanism is installed at a position inside the housing 10 at the bottom of the power storage mechanism, and the adjusting mechanism is used to adjust the elastic force of the turning plate 3 to twist;

[0039] A buffer mechanism is installed on the upper surface of the linkage plate 12, and the buffer mechanism is used to protect the heel;

[0040] An auxiliary mechanism is installed at the top of the mounting bracket 7, and the auxiliary mechanism is used to help lift the foot surface.

[0041] The top edge of the thermal insulation shoe cover 5 covers the ankle position, the inner surface of the thermal insulation shoe cover 5 is provided with fluff, and the fluff has a heat preservation effect. The first fixing belt 15 and the second fixing belt 17 are a kind of magic tape, which is used to fix the thermal insulation shoe cover 5 on the upper surface of the rotating plate 11.

[0042] Among them, the fluff inside the thermal insulation shoe cover 5 is suitable for cold seasons. In seasons with higher temperatures, the fluff inside the thermal insulation shoe cover 5 can be replaced with cotton cloth to increase the air permeability and comfort of the thermal insulation shoe cover 5.

[0043] More importantly, the material of the linkage plate 12 is made of aluminum alloy, which reduces the mass while ensuring that the structural strength of the linkage plate 12 remains unchanged after long-term use. The material of the plug rod 18 is made of carbon steel, which ensures that the plug rod 18 does not deform after long-term use.

[0044] In this embodiment, the patient's foot is inserted into the inside of the heat-preserving shoe cover 5. Due to the symmetrical design of the heat-preserving shoe cover 5, it can be used for both the left and right feet. The first fixing strap 15 is fixed to the upper surface of the rotating plate 11 through the first fixing strap 15 and the second fixing strap 17. Since ankle arthritis can cause foot drop, the foot drop caused by ankle arthritis is corrected by lifting the foot surface upward, flipping the foot surface left and right, and rotating the foot around the first heel as the center. At the same time, the heat-preserving shoe cover 5 plays an effect of keeping the ankle joint warm, preventing the ankle joint from getting cold and aggravating the joint during the correction process.

[0045] Referring to Figure 1 , Figure 2 , Figure 7 and Figure 8 , in a preferred embodiment, the energy storage mechanism includes a fixed block 22 fixedly connected to the inner wall of the outer shell 10. One side of the fixed block 22 is fixedly connected to a fixed cylinder 14. A plurality of short grooves 36 are provided on the outer wall of the fixed cylinder 14. A long groove 37 is provided on the outer wall of the fixed cylinder 14 near the short grooves 36. Connecting rods 35 are respectively fixedly connected to both sides of the fixed cylinder 14. The bottom of the connecting rod 35 is fixedly connected to a bottom ring 33. A plurality of auxiliary grooves 34 are provided on the outer wall of the bottom ring 33. A rotating column 31 is slidably connected to the inside of the fixed cylinder 14. The bottom end of the rotating column 31 is rotatably connected to a sliding rod 13. One end of the sliding rod 13 is sleeved with an energy storage spring 30. The bottom end of the sliding rod 13 is slidably connected to a stable disk 21.

[0046] One end of the linkage plate 12 is provided with a movable groove. The sliding rod 13 is slidably connected to the movable groove. The stable disk 21 is fixedly connected to the inner wall of the outer shell 10. A limiting rod 32 is fixedly connected to one side of the rotating column 31. A slideway is formed among the plurality of auxiliary grooves 34, short grooves 36 and long grooves 37. The limiting rod 32 slides inside the slideway. Through the auxiliary action of the auxiliary grooves 34, the limiting rod 32 slides from the long groove 37 into the short groove 36, and then slides from the inside of the short groove 36 into the long groove 37.

[0047] In this embodiment, during the first upward movement of the patient's instep, the rotating plate 11 drives the linkage plate 12 to rotate up and down, the linkage plate 12 drives the sliding rod 13 to slide up and down, drives the rotating column 31 to slide up and down, and through the auxiliary effect of the auxiliary groove 34, the limiting rod 32 slides from the long groove 37 into the short groove 36. The sliding rod 13 squeezes the energy storage spring 30 to make the energy storage spring 30 form a downward thrust. Since the position of the limiting rod 32 in the short groove 36 is lower than that of the limiting rod 32 inside the long groove 37, the sliding rod 13 squeezes the energy storage spring 30 to form a greater downward thrust. When the patient raises the instep for the second time, the downward thrust of the energy storage spring 30 drives one end of the linkage plate 12 and the rotating plate 11 to rotate downward, thereby helping the patient raise the instep. Due to ankle arthritis causing weakness in the instep muscles of the patient, during the second lift, the burden on the instep muscles of the patient is reduced by the energy storage of the energy storage spring 30, achieving the effect of protecting the patient's joints.

[0048] Among them, through the downward thrust of the energy storage spring 30 of the energy storage mechanism, during the process of the patient lifting the foot, the linkage plate 12 and the rotating plate 11 help the patient reduce the burden on the ankle.

[0049] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 Referring to

[0050] and

[0051] In this embodiment, during the process of turning the instep left and right, by rotating the handle 20, the bidirectional threaded rod 19 can be driven to rotate, controlling the two pressing plates 27 to approach or move away from each other, increasing or decreasing the elastic force inside the two load springs 26. When the rotating plate 11 drives the turning plate 3 to turn through the connecting block 2, the buffer spring 25 is driven by the insertion rod 18 to squeeze the load springs 26 on both sides, achieving the effect of controlling the resistance of the patient's turning instep.

[0052] Among them, the energy storage mechanism and the adjustment mechanism are used in combination. The energy storage mechanism is used to reduce the burden of the patient lifting the foot. The adjustment mechanism adjusts the force of the patient turning the foot to both sides through the load spring 26. The energy storage mechanism and the adjustment mechanism cooperate to jointly perform comprehensive rehabilitation training on the patient's foot and ankle joint.

[0053] Referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In a preferred embodiment, the buffer mechanism includes a buffer disc 23 slidably connected to the top of the rotating disc 24. A buffer spring 25 is provided at the bottom of the buffer disc 23, and a protrusion is provided on the upper surface of the buffer disc 23.

[0054] A rubber pad is provided on the surface of the protrusion, and the rubber pad serves to buffer the heel position of the thermal insulation shoe cover 5.

[0055] Among them, the thickness of the buffer disc 23 is 10 mm, and the material is ABS plastic.

[0056] In this embodiment, when the patient's foot is inserted into the thermal insulation shoe cover 5, the heel part squeezes the buffer disc 23, and the buffer spring 25 is squeezed through the buffer disc 23, which has the effect of protecting the patient's heel.

[0057] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In a preferred embodiment, the auxiliary mechanism includes a fixing ring 6 fixedly connected to the upper surface of the second fixing band 17, and a guide wheel 16 is rotatably connected to the top end of the mounting frame 7.

[0058] An auxiliary rope 8 is provided between the fixing ring 6 and the first fixing band 15, and a pulling ring 9 is fixedly connected to the top end of the auxiliary rope 8.

[0059] In this embodiment, when the patient has severe ankle arthritis and the patient cannot lift the instep by himself, by pulling the pulling ring 9 by hand, the thermal insulation shoe cover 5 is driven by pulling the fixing ring 6 through the auxiliary rope 8, so that the instep of the patient is lifted, which has the effect of assisting the patient to lift the instep.

[0060] Among them, the patient can control the pulling force of the hand on the pulling ring 9 according to his own illness condition to adapt to the foot rehabilitation training in different situations. At different stages of the foot rehabilitation training of the same patient, the pulling force on the pulling ring 9 is also different. If the ankle condition is not serious, no operation on the pulling ring 9 is required.

[0061] Working principle: When in use, insert the patient's foot into the inside of the heat-preserving shoe cover 5. Due to the symmetrical design of the heat-preserving shoe cover 5, it is used for both the left and right feet. Fix the first fixing strap 15 on the upper surface of the rotating plate 11 through the first fixing strap 15 and the second fixing strap 17. Since ankle arthritis can cause foot drop, correct the foot drop caused by ankle arthritis by lifting the foot surface upward, turning the foot surface left and right, and rotating the foot around the first heel as the center. At the same time, the heat-preserving shoe cover 5 plays the role of keeping the ankle joint warm, preventing the ankle joint from getting cold and aggravating the joint during the correction process. During the first time the patient lifts the foot surface upward, the rotating plate 11 drives the linkage plate 12 to rotate up and down. The linkage plate 12 drives the sliding rod 13 to slide up and down, driving the rotating column 31 to slide up and down. Through the auxiliary function of the auxiliary groove 34, the limiting rod 32 slides from the long groove 37 into the short groove 36. The sliding rod 13 squeezes the energy storage spring 30 to make the energy storage spring 30 form a downward thrust. Since the position of the limiting rod 32 in the short groove 36 is lower than that of the limiting rod 32 in the long groove 37, the sliding rod 13 squeezes the energy storage spring 30 to form a greater downward thrust. When the patient lifts the foot surface upward for the second time, the downward thrust of the energy storage spring 30 drives one end of the linkage plate 12 and the rotating plate 11 to rotate downward, thus helping the patient lift the foot surface. Since ankle arthritis causes the foot surface muscles of the patient to be weak, during the second lift, the burden on the foot surface muscles of the patient is reduced by the energy storage of the energy storage spring 30, playing the role of protecting the patient's joints. During the process of turning the foot surface left and right, the turning handle 20 can be rotated to drive the bidirectional threaded rod 19 to rotate, controlling the two pressing plates 27 to approach or move away from each other, increasing or decreasing the elastic force inside the two load springs 26. When the rotating plate 11 drives the flipping plate 3 to flip through the connecting block 2, the buffer spring 25 is driven by the insertion rod 18 to squeeze the load springs 26 on both sides, playing the role of controlling the resistance size of the patient's foot flipping. When the patient's foot is inserted into the inside of the heat-preserving shoe cover 5, the heel part squeezes the buffer disc 23, and the buffer disc 23 squeezes the buffer spring 25, playing the role of protecting the patient's heel. When the patient's ankle arthritis is relatively severe and the patient cannot lift the foot surface by himself, pull the pulling ring 9 by hand, and drive the heat-preserving shoe cover 5 by pulling the fixed ring 6 through the auxiliary rope 8, so that the patient's foot surface is lifted, playing the role of assisting the patient to lift the foot surface.

[0062] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
