FLEXIBLE MEDICINAL CONTAINER (VERSIONS), METHOD OF INCREASING ITS HOLDING CAPACITY, METHOD FOR MANUFACTURING THE SAME AND METHOD OF FORMING FLEXIBLE CONTAINER (VERSIONS) Russian patent published in 2002 - IPC

FIELD: medicinal equipment. SUBSTANCE: container has transparent front sheet of polymeric layer and opposite rear sheet of flat laminate layer. Method involves welding front and rear sheets along common peripheral edge for forming internal volume defined by materials with increased oxygen and moisture barrier properties to allow container forming thermoplastic materials to be stored for prolonged time without damaging the contents of container. Method further involves supercharging internal volume with gas under pressure for continuous drawing of front and rear sheets outside and, consequently, for increasing holding capacity of container. According to other embodiment, container has several departments divided by means of detachable welded seams for holding diluent and medicinal drug. Welded seams are separated during handling of container so as to provide for mixing of substances contained in departments for further injection of mixture into patient's body by means of standard intravenous equipment. EFFECT: simplified construction and method and increased holding capacity of container without changing standard dimensions thereof. 51 cl, 17 dwg
