    • The present invention relates to a method and apparatus for the encapsulation of biologically-active substances in red blood cells, characterized by an optionally automated, continuous-flow, self-contained electroporation system (5) which allows withdrawal of blood from a patient, separation of red blood cells, and optional recombination of blood plasma and the modified red blood cells thereby producing blood with modified biological characteristics. The present invention is particularly suited for use to encapsulate allosteric effectors of hemoglobin, thereby reducing the affinity of erythrocytes for oxygen and improving the release of oxygen from erythrocytes in tissues. The blood is introduced into the system (5) at inlet (11) and mixed with an anticoagulant (27). The blood and anticoagulant mixture is passed through a filter (18) and to a blood separation and wash bowl (44). Plasma and white blood cells are admitted into the plasma reservoir (89) while the red blood cells are retained in the wash bowl (44). The separated red blood cells are pumped out and admixed at junction (67) withan IHP solution from reservoir (50). This mixture is cooled by cooling coil (68) and then pumped to electroporation chamber (72) for treatment.
    • 本发明涉及用于将生物活性物质包封在红细胞中的方法和装置,其特征在于可选地自动化的连续流动的独立电穿孔系统(5),其允许从患者中取出血液,分离 的红细胞,以及血浆和修饰的红细胞的任选重组,从而产生具有改良的生物特征的血液。 本发明特别适用于包封血红蛋白的变构效应物,从而降低红细胞对氧的亲和力,改善组织中红细胞释放的氧。 将血液在入口(11)处引入系统(5)中并与抗凝剂(27)混合。 血液和抗凝血剂混合物通过过滤器(18)和血液分离洗涤碗(44)。 等离子体和白细胞进入血浆容器(89),同时红细胞保留在洗涤碗(44)中。 将分离的红细胞泵出并在接合处(67)与储存器(50)的IHP溶液混合。 将该混合物通过冷却盘管(68)冷却,然后泵送到电穿孔室(72)进行处理。
