Disclosed is an infusion preparation for nutrient supply use. It comprises a sugar, amino acids, electrolytes and a fat emulsion. It has an excellent shelf life without causing precipitation, denaturation and the like in spite of the simultaneous presence of these components. Also disclosed is a container filled with infusion liquids comprising a first and a second compartment separated from each other by a separation means, wherein an infusion liquid containing a fat emulsion and a sugar is included in the first compartment and another infusion liquid containing amino acids and electrolytes is included in the second compartment. Further disclosed are an infusion preparation comprising a fat emulsion and a sugar, and an infusion preparation comprising amino acids and electrolytes. An infusion preparation containing a sugar, amino acids, electrolytes and a fat emulsion can be obtained easily and aseptically upon use, by simply removing a separation means attached to the container and mixing the two infusion liquids.

Infusion preparation comprising phospholipid

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.

Oxygen-transferable fluorocarbon emulsion

Oxygen-transferable perfluorocarbon compounds having 9 to 11 carbon atoms such as perfluorodecalin, perfluoro(C.sub.3.sub.-5 -alkylcyclohexanes), perfluoro(C.sub.4.sub.-6 -alkyl tetrahydropyrans), perfluoro(C.sub.5.sub.-7 -alkyltetrahydrofurans), perfluoro(C.sub.5.sub.-7 -alkylmorpholins) and perfluoro(C.sub.9.sub.-11 -trialkylamines) are emulsified in a physiologically acceptable aqueous solution such as Ringer's solution by the aid of a phospholipid as emulsifier and a fatty acid of 8 to 22 carbon atoms, alkali metal salt or monoglyceride thereof as emulsifying adjuvant. The emulsion is stable for a considerable period of time and contains particles having a particle size ranging from 0.05 to 0.3 .mu.. It is usable as a blood substitute or a perfurate for preservation of the internal organs.

Process for preparing stable oxygen transferable emulsion

Oxygen-transferable perfluorocarbon compounds having 9 to 11 carbon atoms such as perfluorodecalin, perfluoro(C.sub.3-5 -alkylcyclohexanes), perfluoro(C.sub.4-6 -alkyl tetrahydropyrans), perfluoro(C.sub.5-7 -alkyltetrahydrofurans), perfluoro(C.sub.5-7 -alkylmorpholins) and perfluoro(C.sub.9-11 -trialkylamines) are emulsified in a physiologically acceptable aqueons solution such as Ringer's solution by the aid of a phospholipid as emulsifier and a fatty acid of 8 to 22 carbon atoms, alkali metal salt or monoglyceride thereof as emulsifying adjuvant.
