Abstract
The method of this invention yields a two phase liquid aqueous system which replicates the two phase heterogeneous physiochemical system of naturally occurring whole human blood. The method produces a composition of matter which comprises a whole blood substitute when polymerized hemoglobin or pyridoxylated-polymerized hemoglobin and preferably, other specific additives are incorporated. When said blood substitute is processed further, a microencapsulated composition with time release characteristics that can transport oxygen is produced. The invention overcomes the obstacles that have prevented the use of modified hemoglobins like pyridoxylated-polymerized hemoglobin in the preparation of oxygen transport systems.
