The primary purpose of a pressure bandages is simply to cover the injured region and control excessive bleeding without restricting normal blood circulation to the area. These bandages have been in existence for decades and have continued to be a lifesaver for millions of people.
They were originally created to stop excessive bleeding caused by wounds or sprains. Pressure bandages also have uses outside of the medical arena. Because the bandages cover an area that normally would be covered by normal bandages, they prevent infection from forming in this otherwise clean, healthy area. Another use for pressure bandages is to control bleeding caused by surgical wounds. Pressure bandages also have the ability to prevent blood clots from forming after surgery. As the patient is recovering from surgery, blood clots can form in the area around the incision. They can then be difficult to remove. A bandage like this will keep the incision area clean and free from blood clots, which means there are less pain and irritation for the patient.
Another way that pressure bandages can be used post-surgical is to control excessive bleeding from wounds or hemorrhoids. Hemorrhoids are caused when veins in the rectum and anus become swollen. A tourniquet, which is like a bandage, is used to control this swelling and to reduce the chance of it becoming infected. Many hospitals and medical practices in the U.S. even have hemostatic dressings available to control severe bleeding due to hemorrhoids. This dressing includes materials that expand and contract to ensure that the wound stays clean and free of irritation. The demand for these bandages in the U.S. is expected to increase with high cases of sport-related injuries. According to the National High School Sports-Related Injury Surveillance Study 2017-2018, 1,367,490 cases of sport-related were recorded in high schools in the U.S.
