Abstract
Official abstract text for this publication.
Embodiments of methods, systems, and apparatuses for lyophilizing, storing, and transfusing materials are described. In embodiments, the materials may include whole blood or a component of whole blood such as plasma.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of lyophilizing material, the method comprising: maintaining a material in a container; subjecting the material to a first pressure; evaporating at least a portion of a liquid component of the material while adding thermal energy to the material; cooling the material to freeze any remaining liquid component into a solid; pressing the material during the cooling by physical contact between a pressing means and an upper portion of the container and and physical contact between the upper portion of the container and the material thereby controlling a cross-section of the material to reduce variation in cross section of the material; subjecting the material to a second pressure which is less than the first pressure; and sublimating a portion of the solid while adding thermal energy to the material. 2. The method of claim 1 , wherein the sublimating comprises adding IR energy to the material. 3. The method of claim 1 wherein the pressing means is a shelf system. 4. The method of claim 1 wherein the pressing means is a flexible bladder. 5. The method of claim 4 wherein the flexible bladder may be filled with a fluid.
