IMPOVED CONTAINERS FOR PARENTERAL FLUIDS AND METHOD FOR THEIR PREPARATION

摘要

The container is used for the storage of parenterally appliedsubstances, sensitive to oxygen. It is formed of an inner basiccontainer (31, 32, 33) enveloped by nature in anoxygen-impermeable outer coating with oxygen absorber enabling thefull residual oxygen consumption after the outer coating when itis closed, and the oxygen penetrating into the coating for asufficiently long period. The outer container is made ofpolypropylene containing elastic polymer material compatible withthe lipophilic substances, also allowing both of permanent and ofseparating compounds. The coating is made by nature of waterimpermeable elastic multilayer polymer material which includesfirst outer water impermeable polymer film forming an oxygenpartition and connected to a second inner polymer film for theformation of an additional oxygen barrier (50). The containerkeeps entirely its characteristics after any subjection tosterilization by means of steam or irradiation.48 claims, 2 figures
