Compression Socks Were First Used in The Therapeutic Field

Compression stockings have been used for decades in patients with chronic venous insufficiency to improve venous return and reduce swelling and thrombosis in the lower extremities by applying gradient pressure from bottom to top. So how does it work?

As we all know, the heart drives the blood flow throughout the body. When the blood returns through arteries and capillaries to the veins, the power is significantly reduced, and the venous blood in the lower extremities needs to do work against gravity to return to the heart. Can venous blood flow back? Hey, the human body is amazing, there are usually double valves in the veins, from the bottom to the top of the return, the valve attached to the wall of the blood vessel, does not cause obstruction, once standing or other causes of venous pressure increases, the two valves will open, prevent venous blood countercurrent.

However, standing or sitting time is too long, calf venous blood return is slow, you will feel calf swelling, numbness. And patients with chronic venous insufficiency usually have lower limb blood flow retards, valve insufficiency and other symptoms, the common is varicose veins, at this time to apply a bottom-up pressure can promote venous blood return, at the same time can give a positive pressure to the valve, to help improve valve function, this is the function of compression stockings. Therefore, the most important role of compression socks in medical treatment is to promote venous return and prevent deep vein thrombosis.
