  • Process for preparing injection-purpose fluorocarbon emulsion capable of carrying oxygen
    Patent number: 3958014
    Abstract: An injectable fluorocarbon emulsion capable of carrying oxygen, which can be used as artificial blood and organ perfusate, is prepared by emulsifying a fluorocarbon, having an ability to dissolve at least 30 V/V % of oxygen under a 100% oxygen atmosphere at an atmospheric pressure, in an aqueous salt solution with a surfactant, centrifuging the resulting aqueous emulsion thereby to reduce the fluorocarbon particles in the emulsion in size to particle sizes of the order of about 0.05 to 0.25 .mu., and then sterilizing the thus obtained emulsion under rotation. The resulting fluorocarbon emulsion can be used as an emergency blood substitute for transfusion.
