Description

Technical Field

[0001] This invention relates to the field of rehabilitation training devices, specifically a rehabilitation training device for lower limb lymphedema. Background Technology

[0002] Lower extremity lymphedema is a chronic disease caused by lymphatic system dysfunction, leading to fluid accumulation in the tissues and swelling of the lower extremities. It is commonly seen after infection, surgery, tumor treatment, or congenital lymphatic abnormalities. Main symptoms include lower extremity swelling, skin hardening, and limited mobility. Rehabilitation for lower extremity lymphedema can be achieved through muscle movement training, limb positioning, and lymphatic drainage massage. Currently, common lymphedema treatment devices are usually simple support structures used to elevate the legs and promote lymphatic drainage. These devices are often ineffective or even non-functional for training patients with lymphedema. When patients get out of bed for training, their positioning hinders lymphatic drainage, resulting in poor training outcomes and hindering rehabilitation. Summary of the Invention

[0013] As a preferred embodiment of the present invention, fixing straps are provided on both sides of the first rotating plate and both sides of the second rotating plate, and several sets of fixing straps are provided.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The lower limb lymphedema rehabilitation training device of the present invention uses a fixing strap to fix the patient's lower limb to prevent the patient's lower limb from falling off the training device during use. The first rotating plate and the second rotating plate are used to elevate the patient's lower limb. By elevating the patient's lower limb, the lymph fluid in the interstitial space can be refluxed. When the patient's lower limb applies pressure to the first rotating plate, the first rotating plate pushes the moving plate along the positioning rod through the connecting plate. During the movement of the moving plate, the first spring is squeezed, and the first spring applies resistance to the movement of the moving plate, which facilitates the rehabilitation training of the patient's lower limb.

[0015] 2. In the lower limb lymphedema rehabilitation training device of the present invention, during the training process, the person can rotate the nut to squeeze or release the first spring. By adjusting the elastic sensitivity of the first spring, the resistance of the first rotating plate when rotating can be adjusted, so as to be suitable for patients with different physical conditions.

[0016] 3. In the lower limb lymphedema rehabilitation training device of the present invention, the patient bends his / her lower limb and the lower leg squeezes the second rotating plate. The second rotating plate pushes the adjusting plate along the guide rod through the drive plate on the side of the fixed seat. During the movement of the adjusting plate, the second spring is squeezed. The second spring applies resistance to the rotation of the second rotating plate, which makes it easier for the patient to bend his / her leg to further train the lower limb. After the meridians of the patient's lower limb are unblocked, the supporting leg is kept in a raised position to promote the return of lymph fluid. During the process of the patient raising his / her leg straight, the lower limb is supported by the first rotating plate and the second rotating plate.

[0017] 4. The lower limb lymphedema rehabilitation training device of this invention controls the motor unit to drive the drive screw to rotate. The drive screw drives the moving seat to move the squeezing roller inside the protective box under the action of the thread. When the squeezing roller moves to the position of the massage rod, it applies force to the massage rod and pushes the massage rod out from the installation port. After being pushed out, the massage rod presses on the patient's leg to play a massage role. By controlling the forward and reverse rotation of the motor unit, the squeezing roller moves back and forth inside the protective box, which facilitates the use of the massage component. By massaging the calf, lymphatic fluid return can be assisted, which is conducive to the treatment of patients with lower limb lymphedema.

[0018] 5. The lower limb lymphedema rehabilitation training device of the present invention controls the air pump group to draw air from the outside. The air drawn by the air pump group is discharged into the protective box and sprayed out through the gap between the massage rod and the installation port. The sprayed airflow acts on the patient's calves, which plays a role in ventilation and sweating and reduces pressure sores on the patient's legs. Attached Figure Description

[0024] The training component includes a mounting base 6 installed on the side of a support plate 1. A positioning rod 7 is fixed inside the mounting base 6. A movable plate 8 is slidably mounted on the positioning rod 7. A connecting plate 9 is rotatably mounted on the side of the movable plate 8. The side of the connecting plate 9 away from the movable plate 8 is rotatably connected to the side of a first rotating plate 2. The rotatable connection method includes, but is not limited to, a rotatable connection via a rotating shaft or a hinged connection via a hinge seat. A first spring 10 is sleeved on the outside of the positioning rod 7, located between the movable plate 8 and the mounting base 6, and the first spring 10 is located away from the first rotating plate 2. When the patient's lower limb applies pressure to the first rotating plate 2, the first rotating plate 2 pushes the movable plate 8 along the positioning rod 7 through the connecting plate 9. During the movement of the movable plate 8, the first spring 10 is squeezed, and the first spring 10 applies resistance to the movement of the movable plate 8, which is used for the patient's lower limb rehabilitation training.

[0025] The end of the positioning rod 7 away from the first rotating plate 2 is threaded, and a nut 11 is threadedly connected to the side of the positioning rod 7. The first spring 10 is located between the moving plate 8 and the nut 11. During the patient's lower limb training, the person can rotate the nut 11 to squeeze or release the first spring 10. By adjusting the elastic sensitivity of the first spring 10, the resistance of the first rotating plate 2 during rotation can be adjusted, thus making it suitable for training patients with different physical conditions.

[0026] An elastic positioning component is provided between the first rotating plate 2 and the second rotating plate 3. The elastic positioning component is used to limit the connection between the first rotating plate 2 and the second rotating plate 3, so that the first rotating plate 2 and the second rotating plate 3 are on the same straight line, which makes it easier for the patient to raise their straight leg. When the patient's lower limb is bent, the second rotating plate 3 squeezes the elastic positioning component, which can be used for the patient's lower limb training.

[0027] A fixed base 12 is fixed to the lower side of the second rotating plate 3. A drive plate 14 is rotatably mounted on the side of the fixed base 12. A guide rod 15 is fixed to the side of the first rotating plate 2. An adjusting plate 13 is slidably mounted on the guide rod 15. The end of the drive plate 14 away from the fixed base 12 is rotatably connected to the adjusting plate 13. The elastic positioning component includes a second spring 16 sleeved on the outside of the guide rod 15. The second spring 16 is located on the side of the adjusting plate 13 away from the drive plate 14. When the patient's lower limb is bent, the lower leg squeezes the second rotating plate 3. The second rotating plate 3 pushes the adjusting plate 13 along the guide rod 15 through the drive plate 14 on the side of the fixed base 12. During the movement of the adjusting plate 13, the second spring 16 is squeezed. The second spring 16 applies resistance to the rotation of the second rotating plate 3, which facilitates the patient to bend the leg to further train the lower limb. After the patient's lower limb meridians are unblocked, the supporting leg is kept in a high-raised state to promote lymphatic fluid return. During the process of the patient's straight leg being raised, the first rotating plate 2 and the second rotating plate 3 support the lower limb.

[0028] A massage component is provided on the side of the second rotating plate 3. Several mounting ports are opened on the side of the second rotating plate 3.

The push component pushes the massage rod 18 to move back and forth within the mounting port for calf massage. Lower limb lymphedema usually occurs in the calf. Massaging the calf can help lymphatic fluid return and facilitate the treatment of patients with lower limb lymphedema.

[0029] The push assembly includes a movable seat 20 slidably disposed within a protective box 17. A squeezing roller 19 is rotatably mounted on the side of the movable seat 20. A drive assembly for moving the movable seat 20 is disposed within the protective box 17. The drive assembly includes a motor unit 22 mounted on the side of the protective box 17. A drive screw 21 is mounted on the output shaft of the motor unit 22 and is rotatably disposed within the protective box 17. The drive screw 21 is threadedly connected to the movable seat 20. Controlling the motor unit 22 to work drives the drive screw 21 to rotate. Under the action of the thread, the drive screw 21 drives the movable seat 20 to move the squeezing roller 19 within the protective box 17. When the squeezing roller 19 moves to the position of the massage rod 18, it applies force to the massage rod 18, pushing the massage rod 18 out of the mounting opening. After being pushed out, the massage rod 18 presses on the patient's legs, providing a massage effect. By controlling the forward and reverse rotation of the motor unit 22, the squeezing roller 19 moves back and forth within the protective box 17, facilitating the use of the massage assembly.

[0030] The second rotating plate 3 is equipped with a blowing assembly on its side. The blowing assembly includes an air pump group 23 installed on the side of the protective box 17. The air outlet of the air pump group 23 is located inside the protective box 17. A gap is reserved between the massage rod 18 and the mounting port. The air pump group 23 is controlled to draw air from the outside. The air drawn by the air pump group 23 is discharged into the protective box 17 and sprayed out through the gap between the massage rod 18 and the mounting port. The sprayed airflow acts on the patient's calves, which can play a role in ventilation and sweating, and reduce pressure sores on the patient's legs.

[0031] The protective components include arc-shaped protective pads 4 installed on the sides of the first rotating plate 2 and the second rotating plate 3. The arc-shaped protective pads 4 are used to improve the comfort of using the first rotating plate 2 and the second rotating plate 3. The arc-shaped protective pads 4 on the side of the second rotating plate 3 are provided with through holes at the positions corresponding to the installation openings. The massage rod 18 is slidably disposed in the through holes, and the length of the massage rod 18 is adaptively adjusted according to the depth of the through holes and the depth of the installation openings. The through holes facilitate the movement of the massage rod 18 within the arc-shaped protective pads 4 to contact the patient's legs for massage.

[0032] Fixing straps 5 are provided on both sides of the first rotating plate 2 and both sides of the second rotating plate 3, and there are several sets of fixing straps 5. The fixing straps 5 on the side of the first rotating plate 2 are used to fix the patient's thigh, and the fixing straps 5 on the side of the second rotating plate 3 are used to fix the patient's lower leg. The fixing straps 5 fix the patient's lower limbs to prevent the patient's lower limbs from falling off the training device when the device is used, thus facilitating the use of the training device.

[0033] The motor assembly 22, air pump assembly 23, etc. used in this invention are all commonly used electronic components in the prior art. Their working methods and circuit structures are all known technologies. The operation of electronic components such as motor assembly 22 and air pump assembly 23 is controlled by setting a switch group or PLC controller outside the support plate 1. This method is a common technical means used by technicians and will not be described in detail here.

[0034] When using: The patient's lower limbs are secured by a fixing strap 5 to prevent them from detaching from the training device during use. The first rotating plate 2 and the second rotating plate 3 are used to elevate the patient's lower limbs, facilitating lymphatic drainage from the interstitial spaces. When the patient's lower limbs apply pressure to the first rotating plate 2, the first rotating plate 2 pushes the moving plate 8 along the positioning rod 7 via the connecting plate 9. During movement, the moving plate 8 compresses the first spring 10, which provides resistance to the movement of the moving plate 8, facilitating lower limb rehabilitation training. During training, the user can rotate the nut 11 to compress or release the first spring 10. By adjusting the elastic sensitivity of the first spring 10, the resistance during the rotation of the first rotating plate 2 can be adjusted, making it suitable for patients with different physical conditions.

[0035] When the patient bends their lower limb, the lower leg presses against the second rotating plate 3. The second rotating plate 3 pushes the adjusting plate 13 along the guide rod 15 through the drive plate 14 on the side of the fixed seat 12. During the movement of the adjusting plate 13, the second spring 16 is compressed. The second spring 16 applies resistance to the rotation of the second rotating plate 3, which facilitates the patient to bend their leg to further train their lower limb. After the meridians of the patient's lower limb are unblocked, the supporting leg is kept in a raised position to promote lymphatic drainage. During the process of raising the straight leg, the lower limb is supported by the first rotating plate 2 and the second rotating plate 3.

[0036] The control motor unit 22 drives the drive screw 21 to rotate. Under the action of the screw thread, the drive screw 21 drives the moving seat 20 to move the squeezing roller 19 within the protective box 17. When the squeezing roller 19 moves to the position of the massage rod 18, it applies force to the massage rod 18 and pushes it out from the mounting port. After being pushed out, the massage rod 18 presses on the patient's leg, providing a massage effect. By controlling the forward and reverse rotation of the control motor unit 22, the squeezing roller 19 moves back and forth within the protective box 17, facilitating the use of the massage component. Massaging the calf can assist in lymphatic drainage, facilitating the treatment of patients with lower limb lymphedema.

[0037] The air pump unit 23 is controlled to draw air from the outside. The air drawn by the air pump unit 23 is discharged into the protective box 17 and sprayed out through the gap between the massage rod 18 and the installation port. The sprayed airflow acts on the patient's calves, which can help to ventilate and sweat, and reduce pressure sores on the patient's legs.

[0038] This lower limb lymphedema rehabilitation training device is used for lower limb training when patients are bedridden. It assists lymphatic fluid return by raising the legs, which facilitates the rehabilitation treatment of patients with lower limb lymphedema. During the training process, medical staff can adjust the strength of this training device according to the patient's physical condition, making it suitable for different people. At the same time, this training device can be used to massage the patient's calves, which helps to unblock the meridians, promote lymphatic fluid return, and has a ventilation and sweating effect, making it convenient for patients to use.
