I. Principle of medical compression stockings Medical compression stockings are a kind of product with the function of promoting venous blood flow back to heart K. The material is Lycra and nylon silk. The medical compression stocking establishes the highest support pressure at the ankle and gradually decreases up the leg. In the calf, the pressure is reduced to 70%-90% of the maximum value, and in the thigh, it is reduced to 25%-45% of the maximum pressure. This decreasing pressure change can make the lower extremity venous blood return, effectively relieving or improving the lower extremity veins and venous valves under pressure. Second, the medical pressure reducing elastic stockings for people 1, long time standing: teachers, traffic police, shopping guides, beauticians, doctors, nurses, etc. 2, long time sitting: IT people, white-collar workers, civil servants and other office workers —– long time standing or sitting: because of muscle fatigue and gravity, resulting in poor blood flow back to the legs, blood viscosity increases leading to lower limb venous disease. 3, pregnant women, long-term use of contraceptives – pregnancy, hormonal changes in the body, blood volume increased by more than 20%; fetus and the enlarged uterus compression of the pelvic veins and iliac veins, pregnancy weight increase, leg venous pressure increased, resulting in poor blood return, resulting in lower limb venous disease. 4, frequent business trips, travel by airplane, long-distance car crowd, flight attendants —- usually called economy class syndrome, due to weightlessness at high altitude, resulting in poor blood return to the legs, resulting in lower limb venous disease, and in serious cases prone to pulmonary embolism. 5, obese people – due to high cholesterol and blood lipids within the blood, blood viscosity increases, coupled with high weight makes it difficult for venous blood to return to the heart K, leading to lower limb venous disease. 6.People who have already suffered from lower limb vein disease —- because the vein is already in the disease state, must be improved by treatment, otherwise the disease will continue to develop. 7.People with high incidence of lower limb deep vein thrombosis – patients after major surgery, patients with malignant tumor, patients with hemiplegia, women and a women in late pregnancy, patients with lower limb fracture, patients with serious infection, elderly people and so on. Thirdly, what is the function of medical sequential decompression elastic stockings 1, restore the function of lower limb veins after surgery. Prevent and cure the recurrence of varicose veins. 2.Eliminate the edema after various surgeries and promote the wound K-healing. 3.Eliminate the swelling and soreness caused by varicose vein and lower limb vein blood return obstruction, and make the darkened and hardened skin gradually turn better and the ulcerated skin heal. The varicose veins that have become less varicose are restored to their original state. 4.Prevent deep vein thrombosis of lower limbs in long term bedridden patients. 5.Eliminate the lower limb edema of pregnant women in late pregnancy, and prevent the varicose veins and deep vein thrombosis of lower limb of women after giving birth to a. 6.Prevent and control economy class syndrome of air travelers. 7.It can reduce the discomfort of lower limb soreness and swelling to prevent varicose veins of lower limb for those who stand, sit and work for a long time. The best time to wear compression stockings is in the morning when you wake up, because the leg vascular system is in the state of maximum function and swelling has not yet occurred. 1.Put one hand into the sock and pinch the sock two inches inside the head, and turn the sock to the heel with the other hand. 2. Turn most of the sock over and smooth it out so that the foot can easily reach into the toe of the sock. 3.Put your thumbs on the inside of the sock, grab the body of the sock with your four fingers, put your foot inside the sock, hold the sock tightly outward with your thumbs, pull the sock toward the ankle with your four fingers and thumbs, and put the heel of the sock in the correct position. 4.Turn the sock leg back and pull upwards in order, and smooth the sock against your body after putting it on. Take special care not to scratch the stockings with your rings or long nails when putting on or taking off the stockings. Cut your fingernails regularly and prevent skin cracking on your heels during the dry season to avoid scratching your stockings. Also, check the inside of your shoes frequently to prevent unnecessary wear and tear on your stockings. Wash them in warm water with neutral detergent, do not wring them out, squeeze them by hand or use a dry towel to absorb excess water, and dry them in a cool place, not in the sun or under artificial heat sources. Any high quality product, only with careful care can extend its life and achieve the best use. Please consult your doctor before purchasing and come in person to measure your size to avoid using elastic stockings that are not suitable for you.
