Abstract
A system and methodology for the preservation of red blood cells is described in which red blood cells are oxygen or oxygen and carbon dioxide depleted, treated and are stored in an anaerobic environment to optimize preparation for transfusion. More particularly, a system and method for extended storage of red blood cells from collection to transfusion that optimizes red blood cells prior to transfusion is described.
Claims18
A method for preparing whole blood for transfusion comprising:
- obtaining whole blood;
- depleting oxygen and carbon dioxide from said whole blood prior to storage to prepare oxygen and carbon dioxide depleted whole blood;
- storing said oxygen and carbon dioxide depleted whole blood in a anaerobic storage bag comprising an outer bag having a barrier film that is impermeable to oxygen and carbon dioxide, an inner bag in contact with said whole blood, and an oxygen and carbon dioxide sorbent disposed between said inner bag and said outer bag.
A kit for the collection and storage of whole blood comprising
- a phlebotomy needle;
- a collection bag having an anticoagulant solution;
- a depletion device comprising a housing, a plurality of membranes permeable to both oxygen and carbon dioxide and are adapted to receiving and conveying whole blood extending within the housing from an entrance to an exit thereof;
- an amount of both an oxygen sorbent and carbon dioxide sorbent packed within the housing and contiguous to said plurality of membranes;
- and
- a storage bag comprising an outer bag having a barrier film, an inner bag in contact with said whole blood, and a sorbent disposed between said inner bag and said outer bag.
