Bandage

A bandage is a piece of material used either to support a medical device such as a dressing or splint, or on its own to provide support for the movement of a part of the body. When used with a dressing, the dressing is applied directly on a wound, and a bandage is used to hold the dressing in place. Other bandages are used without dressings, such as elastic bandages, which are used to reduce swellings or to provide support to a sprained joint. Tight bandages can be used to slow blood flow to an extremity, such as when a leg or arm is bleeding heavily.

Types
Gauze bandage The most common type of bandage is the gauze bandage, a woven strip of material. A gauze bandage can come in any number of widths and lengths and can be used for almost any bandage application, including holding a dressing in place. Adhesive bandage Liquid bandage Compression bandage The term "compression bandage" refers to a wide variety of bandages with many different applications: • Short stretch compression bandages are applied to a limb (usually for treatment of lymphedema or venous ulcers). This type of bandage is capable of shortening around the limb after application and is therefore not exerting ever-increasing pressure during inactivity. This dynamic is called resting pressure and is considered safe and comfortable for long-term treatment. Conversely, the stability of the bandage creates a very high resistance to stretch when pressure is applied through internal muscle contraction and joint movement. This force is called working pressure. • Long stretch compression bandages have long stretch properties, meaning that their high compressive power can be easily adjusted. However, they also have a very high resting pressure and must be removed at night or if the patient is in a resting position. Triangular bandage Also known as a cravat bandage, a triangular bandage is a piece of cloth put into a right-angled triangle, and often provided with safety pins to secure it in place. It can be used fully unrolled as a sling, folded as a normal bandage, or for specialized applications, such as on the head. One advantage of this type of bandage is that it can be makeshift and made from a fabric scrap or a piece of clothing. The Scouting movement popularized the use of this bandage in many of their first aid lessons, as a part of the uniform is a neckerchief which can easily be folded to form a cravat. Tube bandage A tube bandage is applied using an applicator, and is woven in a continuous circle. It is used to hold dressings or splints on to limbs, or to provide support to sprains and strains, so that it stops bleeding. Kirigami bandage A new type of bandage was invented in 2016; inspired by the art of kirigami, it uses parallel slits to better fit areas of the body that bend. The bandages have been produced with 3D-printed molds. ==See also==
