Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a leg supporting device. Background Art

[0002] Paralyzed patients will stay in bed or sit in a chair for a long time. If they sit or stand for a long time without much activity, the superficial veins of the lower limbs will become varicose, which is varicose veins often found in clinical practice. When patients have varicose veins, the blood flow rate of the veins will slow down, and it is very easy to have edema of the legs and feet. The blood return of the deep vein system will slow down, and blood clots may form in the lower limbs. Once blood clots are formed, they may block the blood vessels of the lower limbs, and the increased pressure will cause fluid to enter the tissue space, causing swelling of the legs and feet.

[0003] Paralyzed patients use footstools to support their legs when they are lying in bed or sitting in a chair for a long time, and lift their legs to relieve leg swelling, but the effect of relieving leg swelling is not good. Utility Model Content
