    摘要: 50-95 Parts by weight of a perfluorocarbon compound such as perfluorodecalin, perfluoromethyldecalin, perfluoro alkylcyclohexanes having 3 to 5 carbon atoms in the alkyl, perfluoro alkyltetrahydrofurans having 5 to 7 carbon atoms in the alkyl, perfluoro alkyltetrahydropyrans having 4 to 6 carbon atoms in the alkyl, perfluoroalkanes having 9 to 11 carbon atoms, and 50-5 parts by weight of a perfluoro tert.-amine such as perfluoro tert.-alkylamines having 9-11 carbon atoms, perfluoro N-alkylpiperidines having 4 to 6 carbon atoms in the alkyl, and perfluoro N-alkylmorpholines having 5 to 7 carbon atoms in the alkyl are emulsified in an aqueous medium by the aid of a high-molecular-weight nonionic surfactant have a molecular weight of about 2,000 to 20,000, and phospholipids as emulsifying agent, and fatty acids having 8 to 22 carbon atoms or salts or monoglycerides thereof as emulsifying adjuvant.The resulting oxygen-transferable emulsion having a particle size of 0.05 to 0.25.mu. is very stable for a long period of time, can be mixed with plasma extenders, and retains for long time in the blood stream of animals when it is used as an artificial blood substitute while being excreted very rapidly.
