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: pooling liquid in a container to create pooled liquid; adding a photosensitizer to the pooled liquid; exposing the pooled liquid with the photosensitizer to a light source to create a pathogen reduced liquid; lyophilizing the pathogen reduced liquid, wherein the lyophilizing comprises: cooling the pathogen reduced liquid to freeze a liquid component to create a solid; subjecting the solid to a first pressure, which is less than atmospheric pressure; and sublimating a portion of the solid. 2. The method of claim 1 , wherein the photosensitizer comprises riboflavin. 3. The method of claim 2 , wherein the light source generates light with a wavelength in an ultraviolet range. 4. The method of claim 1 , wherein the liquid comprises human plasma.
