[0002] Lymphedema is a series of pathological changes including tissue edema, chronic inflammation and tissue fibrosis caused by the retention of lymph in the tissue spaces due to lymphatic circulation disorders. It usually occurs in one part of the body, most commonly in the limbs, but can also occur in the face, neck and external genitalia.

[0003] Lymphedema is divided into two categories: primary and secondary. About 1 in every 6,000 newborns develops primary lymphedema due to defects in the development of the lymphatic system. In Africa and Southeast Asia, filariasis is the main cause of secondary lymphedema, with nearly 100 million patients. In other parts of the world, the number of patients with chronic lymphedema is 0.13%-2%, of which secondary lymphedema after tumor treatment accounts for about half. 15%-30% of breast cancer survivors develop secondary limb edema. About 28%-47% of gynecological cancer patients develop secondary lower limb edema after treatment. The remaining 1 / 2 of patients include primary lymphedema, lymphedema caused by venous insufficiency, lymphedema after trauma, and edema after other systemic factors involve the lymphatic system.

[0004] The manifestations of lymphedema are as follows: (1) Slow onset; (2) Early pitting edema; (3) Edema originating from the distal extremities: dorsum of foot, ankle, back of hand; (4) Often with a history of cellulitis; (5) Rarely pain; (6) Feeling of heaviness; (7) Skin changes: dryness, roughness, papilloma growth, skin erosion; (8) Rarely ulcers.

The central axes of the multiple massage rollers 5 are fixed on the linkage plate 6. The second drive shaft 7 is fixedly installed at the center of the linkage plate 6. The massage drive motor 4 drives the second drive shaft 7 to rotate through the third transmission belt device.

[0035] Embodiment 1:

[0036] The base supporting device includes a supporting base 25 and a supporting frame 26 . The top end of the supporting frame 26 is connected and fixed to the transverse supporting plate 15 , and the bottom end of the supporting frame 26 is fixedly connected to the supporting base 25 .

[0037] The support base 25 can be placed directly on one side of the bed or on the ground next to the patient, and the massage device can be placed on the ground through the support base 25.

[0038] Among them, Figure 8 As shown, the linkage piece 6 is a thin sheet structure, and a plurality of circular mounting holes are arranged on the linkage piece, and the central axis of the massage roller 5 is fixed at the circular mounting holes on the linkage piece 6. The function of the linkage piece 6 is to drive the massage roller 5 to rotate simultaneously.

[0039] When this embodiment is in use, the corresponding part of the patient's lymphedema can be directly clamped between the massage devices with adjustable spacing, which can be the patient's arms or legs. Since the spacing between the massage devices is adjustable, the massage devices can be made to fit tightly on both sides of the patient's arms or legs by adjusting the spacing.

[0040] When there are fewer lymphedema areas on the patient's limbs and there is no need for a massage device to slide back and forth for massage, it is only necessary to start the corresponding massage drive motor 4. The massage drive motor 4 drives the corresponding third conveyor belt device to rotate. The rotation of the third conveyor belt device drives the second drive shaft 7 to rotate. The rotation of the second drive shaft 7 drives the linkage plate 6 to rotate at the same time. The rotation of the linkage plate 6 drives multiple massage rollers 5 to rotate at the same time to massage the patient's lymphedema areas. The continuous rotation of the massage rollers can realize automatic massage of the patient's lymphedema areas. The above-mentioned massage device can help the surface lymphatic vessels of the patient's limbs to quickly restore patency, which is convenient for drainage of the lymphedema areas.

[0041] When there are many lymphedema areas on the patient's limbs and the massage device needs to slide back and forth for massage, the corresponding sliding drive motor 1 is started, and the sliding drive motor 1 starts to work and drives the corresponding first conveyor belt device to rotate. The rotation of the first conveyor belt device drives the corresponding first drive shaft 2 to rotate.
