Introducing two new devises for blood warming

Abstract

Blood and blood products should be kept in cold temperatures to avoid hemolysis and preserve sterility and functional integrity of blood components. Patients needing massive transfusion require the blood to be warmed at bedside to avoid cardiac and general hypothermia. Hypothermia due to massive and rapid transfusion in ill and injured patients is associated with adverse side effects which are very difficult to be reversed. Here in, we describe two inventions of portable warming devices for blood and blood products and fluid solutions. These devices have several advantages including reduced contact with blood and blood products, instant preparation of blood for injections, decreased damage to blood and blood products, precise controlling of heating process, avoiding physical and chemical changes in quality of blood and blood products and also avoiding hypersensitivity symptoms due to injections.
