Abstract
Abstract A wound dressing of the occlusive type which may have a capshaped member which is placed over and connected to the skin about the wound to seal the wound from the surrounding atmosphere. The member has valves therein which, when opened, allow fluids to pass into or out of the wounded area, and, when closed, allow an increase in fluid pressure about the wound to prevent further loss of blood out of the wound and to insure the continued flow of blood through the body.
