Abstract
A hemostatic dressing for applying a hemostatic material such as lyophilized thrombin to a wound. The wound dressing includes an impermeable backing material and a sealing member to provide a seal against the skin. The wound dressing enables the application of pressure in order to seal the sealing member against the patient's skin to the wound without the need for attendance by a health care professional. The seal may be applied by a compressive band or by application of a pressure sensitive adhesive. The wound dressing creates a sealed localized procoagulation environment to facilitate the formation of a clot initiated by the presence of substantial quantities of externally supplied lyophilized thrombin or another dry coagulant.
