  • Process for preparing perfluorochemical emulsion artificial blood
    Patent number: 4497829
    Abstract: Particles of perfluoro compound with a lipid coating are emulsified by sonification in aqueous medium, wherein the proportion of perfluoro compound in the emulsion is preferably about 30-75% (w/v) and the proportion of lipid is preferably about 7-9% (w/v). In the resulting stable emulsion 95% of these particles having diameters less than 0.2.mu.. The emulsion is useful as an artificial blood for transport and delivery of oxygen to body tissues.
    Type: Grant
    Filed: August 19, 1983
    Date of Patent: February 5, 1985
    Assignee: The University of Pennsylvania
    Inventor: Henry A. Sloviter

  • Process for prolonging retention of emulsion particles in the bloodstream
    Patent number: 4397870
    Abstract: The retention of coated particles previously infused into the bloodstream of animals may be prolonged by one or more injections of coating substance. For example, the retention of an artificial blood composition comprising emulsified lecithin-coated perfluoro compounds may be prolonged by injection of lecithin.
