Bandages are used to secure and protect the material in the surgical or injured area and are essential for surgery. The simplest one is a single shed, made of gauze or cotton, for the limbs, tail, head and chest and abdomen. The multi-bandage bandage is a bandage of various shapes made by part and shape. The material is a double-layer cotton cloth, in which cotton of different thickness can be sandwiched, and a cloth strip is arranged around it for knotting and fixing, such as eye bandage, back waist bandage, front Chest bandages, abdominal bandages and armor bandages. Special bandages are often used for fixation in the limbs and joints.
Medical gauze is mainly made of bleached gauze material, which is mainly used for clinical wound dressing. These include medical folding gauze blocks, medical sewing gauze blocks, gauze masks, and the like.
