Abstract
A composition of matter which comprises a synthetic whole blood useful as a substitute for whole natural blood and a method of making the same are disclosed. The method of manufacture yields a composition of matter comprised of a two phase coacervate system. The claimed system successfully duplicates the two phase heterogeneous physicochemical system of naturally occurring whole blood. Also, disclosed is a phase of the claimed method of manufacture which produces a composition of matter, useful as a substitute for hematocrit. Also disclosed is an embodiment employing a hemoglobin component selected from stroma free hemoglobin, synthetic liposomes containing stroma free hemoglobin, microencapsulated stroma free hemoglobin, microspheres of albumin containing stroma free hemoglobin, or emulsified droplets of the coacervate phase containing stroma free hemoglobin. It is preferred that the size of the hemoglobin component particles and the globules of the synthetic hematocrit and the synthetic whole blood range in size from 0.1 to 10 microns.
