Abstract
A method of arresting blood flow from a bleeding wound including the steps of (1) providing a solid hemostatic tablet preferably including potassium ferrate and a cation ion exchange resin pressure formed into a tablet for delivery onto a bleeding wound, the tablet defining a proximal portion and a distal portion, (2) applying the proximal portion against the bleeding wound to improve the rate of adhesion to a bleeding wound surface, and then (3) applying pressure against the tablet over the wound site. After the seal is formed from the interaction of blood or exudates with the proximal portion of the tablet, the distal portion of the tablet delaminates from the proximal portion to form a reservoir to stop further bleeding and to provide antimicrobial protection and healing. The tablet may be applied to any surface orientation and take any shape and thickness possible.
