Medical bandages are mainly used to wrap wounds and prevent wound infections. Surgery, orthopedics, varicose veins of the lower extremities, prevention of blood circulation caused by swelling of the limbs, and bandaging of swelling diseases after the removal of the plaster of limb fractures. Do not use on areas where swelling may occur. The main material of the polymer bandage/polyurethane resin coating will adhere to bare skin and clothes. Please wear protective gloves during operation. The product will generate a certain amount of heat during use, and users may feel uncomfortable. Please note that the more layers of polymer (orthopedic synthetic) bandages are wound, the more heat will be generated. If a polymer (orthopedic synthetic) bandage is immersed in water with a temperature higher than 30°C during use, more heat will be generated. Remind the patient to try not to wet the polymer (orthopedic synthetic) bandage, because the skin will not adapt to the wet bandage for a long time.
