[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The lower limb rehabilitation device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] Reference Figure 1 and Figure 2 The lower limb rehabilitation device 100 according to an embodiment of the present utility model includes: an ankle fixation device 10, a massage device and a heating device. The ankle fixation device 10 includes a foot fixation plate 11, a leg fixation plate 12 and an anti-rotation rod 13. The foot fixation plate 11 extends along a first direction (refer to the e1 direction in the figure), and the leg fixation plate 12 is connected to one end of the foot fixation plate 11 in the first direction. The leg fixation plate 12 extends along a second direction (refer to the e2 direction in the figure), that is, the foot fixation plate 11 and the leg fixation plate 12 are generally arranged in an L-shape.

[0027] Reference Figure 1 There are two anti-rotation rods 13, and the two anti-rotation rods 13 are respectively connected to the two sides of the foot fixing plate 11 in the third direction (refer to the e3 direction in the figure). The anti-rotation rods 13 extend along the third direction; wherein, the first direction is perpendicular to the second direction, the first direction is perpendicular to the third direction, and the second direction is perpendicular to the third direction.

[0028] When a patient uses the lower limb rehabilitation device 100 of this utility model and lies on a hospital bed, the anti-rotation rod 13 can limit the foot fixation plate 11, so that the foot fixation plate 11 extends in the vertical direction, preventing the foot fixation plate 11 from rotating and causing the patient to experience foot drop.

[0029] For example, the ratio of the length of the anti-rotation rod 13 extending upward from the foot fixation plate 11 in a third direction to the length of the foot fixation plate 11 in the first direction is greater than or equal to 0.3; specifically, the ratio of the length of the anti-rotation rod 13 extending upward from the foot fixation plate 11 in a third direction to the length of the foot fixation plate 11 in the first direction can be 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, or 0.6. This allows the anti-rotation rod 13 to better perform its anti-rotation function and improves the reliability of the lower limb rehabilitation device 100.

[0030] Reference Figure 1 and Figure 2 The massage device includes a foot massager 21 and a leg massager 22. The foot massager 21 is mounted on a foot fixing plate 11. For example, the foot massager 21 can be a mechanical massage structure or a pneumatic massage structure. For example, the foot fixing plate 11 has a mounting cavity 111 for housing the drive component of the foot massager 21, and a battery can be installed in the mounting cavity 111 to power the foot massager 21.

[0031] By setting up the foot massager 21, the foot massager 21 can massage and stimulate the acupoints on the patient's feet, promote blood circulation in the patient's feet and legs, improve circulatory disorders and insufficient perfusion of peripheral tissues, reduce the risk of pressure sores on the feet and legs, relax the foot muscles, loosen the muscle fibers that adhere to the patient's feet, reduce the stiffness of the foot muscles and lactic acid accumulation that are easily caused by the patient maintaining a fixed posture for a long time, accelerate the excretion of metabolic waste, and reduce the patient's soreness.

[0032] The leg massager 22 is disposed on the surface of the leg fixing plate 12 facing the foot fixing plate 11, and the foot massager 21 extends out of the leg fixing plate 12 in a direction away from the foot fixing plate 11; for example, the leg massager 22 can be a mechanical massage structure or a pneumatic massage structure. For example, the foot fixing plate 11 has a mounting cavity 111 for housing the drive component of the leg massager 22, and a battery can be provided in the mounting cavity 111 to power the leg massager 22.

[0033] By setting up the leg massager 22, the leg massager 22 can massage and stimulate the acupoints on the patient's legs, promote blood circulation in the patient's feet and legs, improve circulatory disorders and insufficient perfusion of peripheral tissues, reduce the risk of pressure sores in the feet and legs, relax leg muscles, loosen the muscle fibers that adhere to the patient's legs, reduce the leg muscle stiffness and lactic acid accumulation that are easily caused by the patient maintaining a fixed posture for a long time, accelerate the excretion of metabolic waste, and reduce the patient's soreness.

[0034] The heating device includes a foot heating element 31 and a leg heating element 32. One end of the foot heating element 31 is connected to one end of the foot fixing plate 11 in a third-party direction, and the other end of the foot heating element 31 is detachably connected to the other end of the foot fixing plate 11 in a third-party direction. For example, one end of the foot heating element 31 can be fixedly connected to one end of the foot fixing plate 11 in a third-party direction, and the other end can be detachably connected to the other end of the foot fixing plate 11 in a third-party direction via Velcro, buckles, or straps. For example, the foot heating element 31 can be a heating element that directly radiates heat outward through the principle of heating by an electrically conductive heating wire, or it can be a heating element that indirectly diffuses energy outward by heating air and blowing the heated airflow. Specifically, when the foot heating element 31 is a heating element that indirectly diffuses energy outward by heating air and blowing the heated airflow, the mounting cavity 111 is used to place the pneumatic components of the foot heating element 31. The pneumatic components may include an air pump, an air tank 224, and a control valve 223.

[0035] When the lower limb rehabilitation device 100 needs to be worn, first remove the other end of the foot heating element 31 from the other end of the foot fixation plate 11 in the third direction. Then place the patient's foot on the foot massager 21, and then connect the other end of the foot heating element 31 to the other end of the foot fixation plate 11 in the third direction. Use the foot heating element 31 to limit and fix the patient's foot.

[0036] By setting the foot heating element 31, the patient's foot can be heated, keeping the patient's foot within a more comfortable range, reducing or avoiding the risk of heat loss from the patient's foot, making the patient's leg blood vessels contract more regularly and normally, effectively promoting blood circulation in the patient's feet and legs, and improving circulatory disorders and insufficient perfusion of peripheral tissues.

[0037] The leg heating element 32 is mounted on the leg fixing plate 12, and its two ends in the third direction are detachably connected. For example, the leg heating element 32 can be connected to the leg massager 22 through its middle in the third direction, and its two ends in the third direction can be detachably connected by Velcro, buckles, or straps. For example, the leg heating element 32 can be a heating element that directly radiates heat outward through the principle of heating by an electrically conductive heating wire, or it can be a heating element that indirectly diffuses energy outward by heating air and blowing the heated air. Specifically, when the leg heating element 32 is a heating element that indirectly diffuses energy outward by heating air and blowing the heated air, the mounting cavity 111 is used to house the pneumatic components of the leg heating element 32, which may include an air pump, an air tank 224, and a control valve 223.

[0038] When the lower limb rehabilitation device 100 needs to be worn, first detach the two ends of the leg heating element 32 in the third direction, remove the other end of the foot heating element 31 from the other end of the foot fixation plate 11 in the third direction, then place the patient's foot on the foot massager 21, place the patient's leg in the middle of the leg heating element 32 in the third direction, then connect the other end of the foot heating element 31 to the other end of the foot fixation plate 11 in the third direction, use the foot heating element 31 to limit and fix the patient's foot, connect the two ends of the leg heating element 32 in the third direction together, and use the leg heating element 32 to limit and fix the patient's leg.

[0039] By setting the leg heating element 32, the patient's legs can be heated, keeping them within a comfortable range, reducing or avoiding the risk of heat loss from the patient's legs, making the blood vessels in the patient's legs contract more regularly and normally, effectively promoting blood circulation in the patient's feet and legs, and improving circulatory disorders and insufficient perfusion of peripheral tissues.

[0040] For example, when the leg heating element 32 is a heating element that indirectly diffuses energy by heating air and blowing the heated air outward, and the leg massager 22 is a pneumatic massage structure, the leg heating element 32 and the leg massager 22 can be an integral part. That is, the leg heating element 32 is used to heat the gas introduced into the foot massager 23, so that the gas introduced into the leg massager 22 has a high heat, so that the leg massager 22 can transfer the heat in the gas to the patient's legs to realize the leg massage function and the leg heating function, making the overall structure of the lower limb rehabilitation device 100 more compact.

[0041] According to the lower limb rehabilitation device 100 of this utility model, by setting up an ankle fixation device 10, a massage device, and a heating device, the massage device can prevent foot drop in patients. The massage device can massage and stimulate acupoints on the patient's feet and legs, promote blood circulation in the feet and legs, improve circulatory disorders and insufficient peripheral tissue perfusion, and reduce the risk of pressure sores on the feet and legs. The heating device can massage the area around the patient's lower limbs and the soles of the feet, promote blood circulation, and repeatedly stimulate and exercise the plantar nerves of long-term bedridden patients through massage. At the same time, it provides a warm environment, which can promote the functional recovery of the patient's lower limbs and soles.

[0042] Reference Figure 1In some embodiments of this utility model, the ankle fixation device 10 further includes: two arc-shaped support plates 14, which are respectively connected to the two sides of the foot fixation plate 11 in the third direction. The two arc-shaped support plates 14 extend towards each other in the third direction and are spaced apart in the third direction. The two arc-shaped support plates 14 and the foot fixation plate 11 together form a foot placement space 15. The two arc-shaped support plates 14 together define a wearing opening 16 in the third direction. This allows the patient's foot to be placed into the foot fixation space through the wearing opening 16.

[0043] Reference Figure 1 The massage device also includes a foot massager 23, which is connected to the side surface of the curved support plate 14 facing the foot fixing plate 11. For example, the foot massager 23 can be a mechanical massage structure or a pneumatic massage structure. The curved support plate 14 can support the foot massager 23 and limit its movement, so that the foot massager 23 can reliably massage the patient's feet.

[0044] By setting up the foot massager 23, the foot massager 23 can massage and stimulate the acupoints on the patient's feet, promote blood circulation in the patient's feet and legs, improve circulatory disorders and insufficient perfusion of peripheral tissues, reduce the risk of pressure sores on the feet and legs, relax the foot muscles, loosen the muscle fibers that adhere to the patient's feet, reduce the stiffness and lactic acid buildup in the foot muscles that are easily caused by the patient maintaining a fixed posture for a long time, accelerate the excretion of metabolic waste, and reduce the patient's soreness.

[0045] In some embodiments of this utility model, the foot massager 23 includes a first driving component and a first moving component. The first driving component is an air pump, and the first moving component is an air bladder. The first moving component has multiple first air chambers. The first driving component is connected to each of the first air chambers via an air supply pipe, and the first driving component is used to inflate each of the first air chambers via the air supply pipe. In this way, by inflating or deflating the first air chambers, the reciprocating motion of the first moving component is realized, thereby achieving the pneumatic massage function of the foot massager 23.

[0046] In some embodiments of this utility model, the foot heating element 31 is disposed in the air supply pipe of the foot massager 23, and the foot heating element 31 is used to heat the gas flowing into the first air chamber. That is, the foot heating element 31 and the foot massager 23 are an integral part, and the foot heating element 31 is used to heat the gas introduced into the foot massager 23, so that the gas introduced into the foot massager 23 has a high heat, so that the foot massager 23 can transfer the heat in the gas to the patient's foot, thereby realizing the foot massage function and the foot heating function, making the overall structure of the lower limb rehabilitation device 100 more compact.

[0047] Reference Figure 2 According to some optional embodiments of this utility model, the foot massager 21 includes a second driving member 211 and a second moving member 212. The second driving member 211 is used to output rotational or linear motion, and the second moving member 212 is a rod. The second moving member 212 is movably mounted on the foot fixing plate 11 along a second direction. The second driving member 211 is connected to the second moving member 212, and the second driving member 211 is used to drive the second moving member 212 to move. In this way, the massage function of the foot massager 21 can be realized through a mechanical structure, so that the foot massager 21 can apply more precise pressure stimulation to the acupoints of the patient's feet, thereby improving the reliability of the foot massager 21.

[0048] Reference Figure 2 In some optional embodiments of this utility model, the second moving member 212 is a rod, and there are multiple second moving members 212, which are spaced apart on the foot fixing plate 11. There is one second driving member 211, which is connected to all the second moving members 212 via a crankshaft 213 or a crank connecting rod to drive all the second moving members 212. For example, there can be two, three, four, five, six, or more second moving members 212. This reduces the number of second driving members 211 in the foot massager 21, thus lowering the cost of the foot massager 21.

[0049] It should be explained that in this utility model, "multiple" refers to two or more.

[0050] Reference Figure 2 In some optional embodiments of this utility model, there are multiple second moving parts 212, which are spaced apart on the foot fixing plate 11. The number of second driving parts 211 is the same as the number of second moving parts 212 and corresponds one-to-one. Each second driving part 211 is connected to a corresponding second moving part 212 to drive the corresponding second moving part 212 to move. This allows for independent control of each second moving part 212, enabling independent control of the movement direction and distance of each second moving part 212. This allows the foot massager 21 to have multiple massage sequences, meeting the diverse needs of users.

[0051] Reference Figure 2 According to some embodiments of this utility model, the heating device further includes a foot heating element 33, which is connected to the side of the foot massager 21 away from the foot fixing plate 11. For example, the foot heating element 33 can be a heating element that directly radiates heat outward through the heating principle of an electrically conductive heating wire, or it can be a heating element that indirectly diffuses energy outward by heating air and blowing the heated airflow.

[0052] By setting the foot heating element 33, the patient's feet can be heated, keeping the patient's feet within a more comfortable range, reducing or avoiding the risk of heat loss from the patient's feet, making the blood vessels in the patient's feet contract more regularly and normally, effectively promoting blood circulation in the patient's feet and legs, and improving circulatory disorders and insufficient perfusion of peripheral tissues.

[0053] Reference Figure 2 The foot heating element 33 includes a fabric layer 331 and a heating layer 332. The fabric layer 331 is disposed on both sides of the heating layer 332. The heating layer 332 includes a metal wire and a thermally conductive insulating film coated on the outer surface of the metal wire. In other words, the foot heating element 33 is a heating element that directly radiates heat outward through the principle of electric heating wire. By setting a thermally conductive insulating film on the outer surface of the metal wire, it can provide insulation and heat conduction for the metal wire, improving the reliability of the foot heating element 33.

[0054] Furthermore, by configuring the foot heating element 33 as a structure of a fabric layer 331 and a heating layer 332, the thickness of the foot heating element 33 can be made thinner, allowing the foot heating element 33 to deform more closely with the movement of the second moving part 212. This enables the foot massager 21 to apply more precise stimulation to the acupoints on the patient's feet through the foot heating element 33, thereby improving the reliability of the lower limb rehabilitation device 100.

[0055] Reference Figure 2 According to some alternative embodiments of the present invention, the leg massager 22 includes a third driving member 221 and a third moving member 222. The third driving member 221 is an air pump, and the third moving member 222 is an airbag. The third moving member 222 has multiple second air chambers 2221. The third driving member 221 is connected to each second air chamber 2221 via an air supply pipe, and the third driving member 221 is used to inflate each second air chamber 2221. For example, the air pump can rotate clockwise to supply air to the second air chamber 2221, or it can rotate counterclockwise to discharge the gas in the second air chamber 2221 through the air supply pipe. For example, each second air chamber 2221 is also connected to an exhaust pipe, and an exhaust air pump is provided in the exhaust pipe to discharge the gas in the second air chamber 2221. In this way, by inflating or deflating the second air chamber 2221, the reciprocating motion of the second moving member 212 is realized, thereby realizing the pneumatic massage function of the leg massager 22.

[0056] Reference Figure 2In some alternative embodiments of this utility model, the leg massager 22 further includes a control valve 223. The control valve 223 is connected to the air outlet of the third drive member 221, and the control valve 223 has multiple connection ports. The number of connection ports is the same as the number of air supply pipes and corresponds one-to-one. Each air supply pipe is connected to its corresponding connection port. The control valve 223 is used to control the opening and closing of each connection port. For example, the exhaust pipe can also be equipped with a control valve 223 to control the opening and closing of the exhaust pipe's air passage.

[0057] This allows for independent control of the inflation and deflation of each second air chamber 2221 by controlling the opening and closing of each connection port and the forward and reverse rotation of the air pump. This enables the multiple second air chambers 2221 to inflate and contract at different times, giving the leg massager 22 a variety of massage sequences to meet the diverse needs of users.

[0058] In some alternative embodiments of this utility model, the leg heating element 32 is disposed in the air supply pipe of the leg massager 22, and the leg heating element 32 is used to heat the gas flowing into the second air chamber 2221. That is, the leg heating element 32 and the leg massager 22 are integrated, and the leg heating element 32 is used to heat the gas introduced into the leg massager 22, so that the gas introduced into the leg massager 22 has a high heat value, so that the leg massager 22 can transfer the heat in the gas to the patient's legs to realize the leg massage function and the foot heating function, making the overall structure of the lower limb rehabilitation device 100 more compact.

[0059] Specifically, refer to Figure 2 The leg massager 22 may also include an air tank 224. An air supply pipe is connected to the air pipe to deliver gas from the air pipe into the second air chamber 2221. An exhaust pipe is connected to the air pipe to discharge gas from the second air chamber 2221 into the air pipe for storage, enabling gas recycling. The leg massager 22 can be located inside the air supply pipe or the air tank 224 to heat the gas. This also allows for gas recycling in the air tank 224, ensuring that the gas carrying more heat discharged from the second air chamber 2221 is discharged into the air tank 224, reducing heating time and energy consumption, thus making the lower limb rehabilitation device 100 more energy-efficient.

[0060] Optionally, the gas tank 224 can be used to supply air to any one of the leg massager 22, leg heating element 32, foot heating element 31, and foot massager 23, so that the lower limb rehabilitation device 100 is more compact overall.
