Container used in portable infusion device comprises rigid base which has perimeter; rigid top part with perimeter; and flexible foldable diaphragm between base and top part. Diaphragm has outer perimeter, tightly secured along base perimeter, and inner perimeter, tightly secured along top part perimeter. Diaphragm is adapted for placement of container top part and base directly adjacent to each other, when container is empty, and placement of top part and base at distance from each other, when container is filled. Portable infusion device comprises base, adapted for attachment to patient's skin; cannula assembly supported on base; pump unit adapted to receive at base in connection with cannula assembly by fluid medium; and above said container adapted to receive by pump unit.EFFECT: invention have minimum speed of water vapour permeability and thereby make it possible to increase storage life of drug.16 cl, 8 dwg |
