[0002] Lower limb edema is a common clinical symptom. Lower limb elevation is often used as an adjunct treatment for patients with lower limb edema. This involves raising the patient's calf above the heart, thereby promoting venous return and accelerating the reduction of leg swelling, thereby alleviating lower limb swelling and pain.

[0003] Existing Chinese patent CN215740089U discloses a lower limb elevation pillow. This pillow comprises an air cushion, a base, and a height adjustment mechanism. The base is a right-angled trapezoidal shell with an upward opening. The air cushion is mounted within the base, and when inflated, its upper end is higher than the base opening. A groove is provided at the top of the air cushion. The height adjustment mechanism comprises a support plate and a lifting mechanism. The support plate is horizontally fixed to the bottom of the air cushion, and the lifting mechanism is mounted below the support plate. While the height can be easily adjusted, the leg length is limited due to the bending points at the thigh and calf. Therefore, it is not suitable for patients with different leg lengths.
