Abstract: Compression stockings are convenient and effective medical textiles for relieving and treating venous diseases of lower limbs. Its safety and effectiveness attract wide attention from the public. Taking a healthy young lady as the object of study, the study measured the changes of the blood flow velocity of the lower limbs via ultrasonic doppler flow detector when wearing different compression stockings at different wearing times, so as to explore the effect of compression stockings on blood flow velocity of lower limbs.The result showed that wearing compression stockings had an obvious inhibitory effect on the blood flow velocity in the distal lower extremity. As the pressure level increases, the rate of decrease in blood flow velocity in the distal extremity became smaller. Meanwhile, the inhibitory effect of wearing compression stockings with a lower pressure level for a long time was basically the same as that of wearing higher pressure level compression stockings for a short time.

Key words: compression stockings; medical textiles; distal lower extremity; blood flow velocity
