Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a rehabilitation treatment device for patients with lower limb edema. Background Technology

[0002] Lower extremity edema is a pathological phenomenon caused by the abnormal accumulation of fluid in the interstitial spaces of the lower limbs due to factors such as poor venous return and lymphatic fluid retention. Long-term or severe lower extremity edema can not only cause heaviness, pain, and numbness in the legs, but may also lead to skin changes, functional impairment, and even serious complications such as deep vein thrombosis. Therefore, treatment for lower extremity edema is crucial. Common treatment methods include medication, physical therapy, and the use of rehabilitation equipment.

[0003] Currently, rehabilitation devices are commonly used to treat patients with lower limb edema. These devices are typically strap-like structures that can be fixed to the patient's leg. Heating wires are usually installed inside the straps to promote blood circulation and relieve discomfort caused by swelling. In addition, some existing rehabilitation devices have protrusions inside the straps for a massage effect, further promoting blood and lymph flow and improving therapeutic efficacy. However, the protrusions in existing rehabilitation devices are usually fixed and cannot effectively interact with the patient's leg during use, thus limiting the full massage effect and consequently restricting the therapeutic effect.

[0020] like Figures 1 to 7 As shown, in a first aspect of this utility model, a rehabilitation treatment device for patients with lower limb edema is provided, comprising: a housing 1, a first fixing part 2, two second fixing parts 3, two massage rollers 4, and a drive assembly 5.

[0021] Two massage rollers 4 are rotatably mounted inside the housing 1. A drive assembly 5 is mounted on the housing 1 and connected to the two massage rollers 4, driving them to rotate simultaneously in different directions. A first fixing part 2 is fixedly connected to the housing 1, and its position corresponds to the two massage rollers 4, used to fix the device to the swollen area of ​​the patient's leg. Two second fixing parts 3 are both connected to the first fixing part 2, and the side of each second fixing part 3 away from the first fixing part 2 is detachably connected. When the second fixing parts 3 are connected to the first fixing parts 2, a leg-accommodating space is formed, facilitating the fixation of the device to the patient's leg. A strap assembly 6 is also connected to the housing 1 to further secure the device to the patient's leg, ensuring that the massage rollers 4 are in contact with the patient's leg for effective massage therapy.

[0022] In use, firstly, attach the first fixing part 2 to the swollen area of ​​the patient's leg, ensuring that the massage roller 4 is in contact with the swollen area. Then, wrap the two second fixing parts 3 around the patient's leg and secure them to the side away from the first fixing part 2. Continue to use the strap assembly 6 to further secure the device, ensuring a firm fixation and that the massage roller 4 remains in contact with the patient's leg. Activate the drive assembly 5, which drives the two massage rollers 4 to rotate simultaneously in different directions. During rotation, the massage rollers 4 reciprocate at a certain angle, with a rotation angle of 30-60 degrees, thereby massaging the patient's leg. Specifically, when the drive assembly 5 drives the two massage rollers 4 to rotate simultaneously in different directions, the two massage rollers 4 reciprocate at a certain angle, with a rotation angle of 30-60 degrees.

[0023] Because the drive assembly 5 can drive the two massage rollers 4 to rotate simultaneously in different directions, this design allows the massage rollers 4 to reciprocate at a certain angle (rotation angle of 30-60 degrees). Unlike traditional fixed protruding massage structures, the rotation of the two massage rollers 4 can produce a dynamic massage effect, effectively contacting the patient's legs, thereby enhancing the massage and blood circulation promotion effect on the edema area and relieving edema symptoms. The first fixing part 2 and the second fixing part 3 of the device are designed to be detachably connected, which can be adjusted according to the actual situation of the patient's legs to accommodate patients with different leg circumferences. The first fixing part 2 is fixedly connected to the housing 1 and corresponds to the massage roller 4, ensuring that the massage roller 4 is always in contact with the edema area during use. The two second fixing parts 3 can be quickly installed and removed by disassembly and reconnection, making it easy to use and reducing the operational difficulty for patients and caregivers. In addition, the strap assembly 6 further secures the device, ensuring stability during the massage process and preventing it from deviating from the target area due to movement.

[0024] In this embodiment, a rotating shaft 41 is disposed through the inside of the massage roller 4. The rotating shaft 41 is fixedly connected to the massage roller 4, and the rotation of the rotating shaft 41 will drive the massage roller 4 to rotate. A drive cavity 11 is provided at the lower end of the housing 1, and one end of the rotating shaft 41 extends into the drive cavity 11. One end of the rotating shaft 41 extends into the drive cavity 11 at the lower end of the housing 1 and is connected to the drive assembly 5, while the other end is fixedly connected to the middle of the massage roller 4. With this structure, the rotating shaft 41 can transmit the power provided by the drive assembly 5, so that the massage roller 4 can rotate. This design ensures that the massage roller 4 can produce a continuous massage effect during treatment. The drive assembly 5 is disposed in the drive cavity 11. The drive assembly 5 includes a motor 51, a drive arm 52, a driven arm 53, and a transmission component 54. The motor 51 is fixedly connected to the drive cavity 11, and its function is to provide driving force. The output end of the motor 51 transmits power through the drive arm 52. The drive arm 52 is connected to the motor 51 via the output end of the motor 51, driving the drive rod 521 to perform circular motion. The drive arm 52 is a key component connecting the motor 51 and the driven arm 53, used to transmit power and guide the movement of the transmission component 54. The two driven arms 53 are fixedly connected to the rotating shaft 41. Each driven arm 53 is provided with a driven rod 531, which cooperates with the transmission groove 541 of the transmission component 54 to control the rotation direction of the rotating shaft 41. The transmission component 54 is slidably installed in the drive cavity 11 and has a transmission groove 541. Both the drive rod 521 and the driven rod 531 extend into the transmission groove 541. Through the reciprocating linear motion of the transmission component 54, the driven arms 53 are driven to rotate in two directions, thereby controlling the reciprocating rotation of the rotating shaft 41.

[0025] After the motor 51 is started, its output end drives the drive rod 521 to perform circular motion via the drive arm 52. The circular motion of the drive rod 521 drives the transmission component 54 to perform reciprocating linear motion. When the transmission component 54 moves in the first linear direction, the transmission groove 541 drives the driven arm 53 to rotate in the first rotational direction via the driven rod 531; when the transmission component 54 moves in the second linear direction, the transmission groove 541 drives the driven arm 53 to rotate in the second rotational direction via the driven rod 531. In this way, the drive assembly 5 can apply power to the rotating shaft 41, causing it to rotate reciprocally. The reciprocating rotation of the rotating shaft 41 drives the two massage rollers 4 to rotate accordingly, thereby massaging the patient's legs.

[0026] The drive assembly 5 of this embodiment enables the massage roller 4 to provide a precise and adjustable massage effect during rotation. The rotation direction and angle of the massage roller 4 can be adjusted by adjusting the operating parameters of the drive assembly 5 to suit the needs of different patients. Compared with the traditional fixed protrusion structure, the dynamic rotation of the massage roller 4 can more effectively stimulate leg muscles and blood vessels, promote blood circulation, relieve lower limb edema, and improve the therapeutic effect.

[0027] In this embodiment, a transmission assembly 7 is also included. A transmission cavity 12 is provided on the housing 1, and the transmission assembly 7 is disposed within the transmission cavity 12. The transmission assembly 7 includes two first gears 71 and two second gears 72. The first gears 71 are fixedly connected to the rotating shaft 41, and the second gears 72 are installed within the transmission cavity 12 and mesh with the first gears 71. The second gears 72 mesh with each other to ensure they can rotate collaboratively.

[0028] When the drive assembly 5 drives the two rotating shafts 41 to rotate, the two rotating shafts 41 will drive the two first gears 71 to rotate, and the rotation of the two first gears 71 will drive the two second gears 72 to rotate. The two second gears 72 mesh with each other and rotate simultaneously in different directions. The transmission assembly 7 can effectively improve the synchronization of the rotation of the two rotating shafts 41 and ensure the stability of the two rotating shafts 41 during the rotation process.

[0029] In this embodiment, two guide rails 14 are provided inside the drive cavity 11, and the transmission component 54 is slidably mounted between the two guide rails 14. By providing guide rails 14, the transmission component 54 can slide smoothly within the drive cavity 11, avoiding noise or instability caused by the offset or friction of the transmission component 54, and ensuring that the device can maintain a stable and efficient working state during operation.

[0030] In this embodiment, the first fixing part 2 includes a base 21, a heating wire 22, and an encapsulation layer 23; the heating wire 22 is disposed between the base 21 and the encapsulation layer 23. The heating wire 22 is arranged in a serpentine pattern and can generate a certain amount of heat during use, helping to relieve lower limb edema through heating. The encapsulation layer 23 effectively protects the heating wire 22, preventing it from directly contacting the skin, thereby improving safety and extending the service life of the heating wire 22. As an optional embodiment, the second fixing part 3 can also have a heating wire 22 disposed inside.

[0031] In this embodiment, the two second fixing parts 3 are detachably connected on the side away from the first fixing part 2 via Velcro. The Velcro connection design allows the second fixing parts 3 to be easily adjusted and removed, facilitating adjustments according to different sizes of the patient's legs, while also increasing the convenience and comfort of the device.

[0032] In this embodiment, the surface of the massage roller 4 is provided with massage protrusions 42. The massage protrusions 42 can come into contact with the patient's leg skin during the massage process. The protruding structure enhances the stimulation and massage effect on the legs, thereby helping to relieve swelling and promote blood circulation.

[0033] In this embodiment, there are two strap assemblies 6. Each strap assembly 6 includes two strap bodies 61. One end of each strap body 61 is fixedly connected to the housing 1, and the ends of each strap body 61 away from the housing 1 are detachably connected by Velcro. The Velcro design allows the strap assembly 6 to be quickly and easily fixed to the patient's leg, and it is also easy to adjust and remove, improving the convenience and comfort of use.

[0034] In this embodiment, the housing 1 includes two arc-shaped plates 13, which are integrally formed, and the two massage rollers 4 protrude from the arc-shaped plates 13. The design of the arc-shaped plates 13 allows the massage rollers 4 to better conform to the patient's legs, thereby providing a more comfortable massage experience. The arc-shaped structure also enhances the massage effect, making it more adaptable to the leg contour and improving the applicability and comfort of the device.

[0035] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
