HemCon dressings control bleeding by becoming extremely adherent when in contact with blood. The adhesive-like action seals the wound and attracts red blood cells to the bandage, forming a seal that stops hemorrhaging independent of the body's natural clotting process. The bandages and dressings provide a barrier against harmful bacteria naturally because when in contact with the bacteria, the chitosan ruptures the cell walls of gram negative bacteria and prohibits reproduction. The antibacterial barrier properties of these bandages help prevent infection transmission to other patients and health care providers and also make it easier for medical professionals to help prevent infections at incision site wounds. This potentially decreases patient complications and length of hospital stay.
