 Celox Haemostats are dressings with natural material called chitosan to control major haemorrhage including life-threatening bleeding . They are simple and effective, stopping major bleeding.It was first used by military forces to stop sever bleeding in the scene with no other options to stop bleeding. CeloxTM granules are actually very high surface area flakes. When they come in contact with blood, CeloxTM swells, gels, and sticks together to make a gel like clot, without generating any heat. CeloxTM does not set off the normal clotting cascade, it only clots the blood it comes directly into contact with. Celox works on casualties using anticoagulants and anti-platelet therapy such as aspirin .
