Description

Technical Field

[0001] This utility model belongs to the field of nursing tools, specifically relating to an adjustable lower limb elevation pad. Background Technology

[0002] Elevating the lower limbs is a common practice in medical care and rehabilitation to promote blood circulation, relieve edema, and aid postoperative recovery, especially in cases of leg injuries, prevention of venous thrombosis, and orthopedic postoperative rehabilitation. Traditional methods of lower limb elevation often use ordinary pillows, wedge-shaped foam pads, or fixed-angle lower limb supports, but these methods have significant drawbacks. Ordinary pillows and foam pads are difficult to maintain a stable height and angle, and are prone to shifting during patient movement, resulting in poor support. Fixed-angle lower limb supports cannot be flexibly adjusted according to individual patient differences (such as body type and injury condition), leading to poor comfort and the potential for pressure injuries due to compression of local tissues. The adjustment of the position and height of the lower limb elevation pillow or pad depends on medical staff; patients cannot adjust it themselves.

[0003] Furthermore, most existing lower limb elevation devices are one-piece structures, which cannot adapt to the different lower limb widths of patients, thus limiting their application scenarios. At the same time, the surface of the devices lacks cushioning materials or removable cleaning parts, making them prone to bacterial growth with long-term use, and they are also difficult to meet the comfort needs of patients with sensitive skin.
