FLEXIBLE CONTAINER FOR STORING PARENTERAL FLUIDS AND METHOD FOR MANUFACTURING IT Russian patent published in 2002 - IPC

FIELD: medical engineering. SUBSTANCE: device has primary internal container enclosed into essentially oxygen-impermeable envelope containing oxygen absorber capable of absorbing practically all residual oxygen when having sealed the external envelope and also oxygen penetrating through the said envelope within enough time. The internal container is manufactured from flexible polymer material containing polypropylene and lipophil agents capable of building both permanent and separable compounds. The envelope is manufactured from practically water-proof flexible multilayer material having the first practically water-proof polymer film capable of building coating essentially impermeable for oxygen connected to the second internal film allowing additional coating impermeable for oxygen to be formed. EFFECT: retained properties after being undergone to sterilization. 46 cl, 3 dwg, 4 tbl
