Abstract
A synthetic bag-type container for human blood and its fractions, and perfusion solutions in general, is constituted by an envelope welded on three sides, with the fourth side configured as a bellows to generate the base of the container, from which the delivery nozzles project, each end of the bellows being defined by two inclined welds which converge into the adjacent lateral weld of the envelope, so as to give the base a concave configuration which ensures perfect emptying of the contents.
Claims12
A generally flat synthetic bag-type container for human blood and its fractions, perfusion solutions, dialysis solutions and alimentary and chemical liquids in general, constituted by a thin flexible walled casing which is in the form of a rectangular envelope having a bellows-shaped base and comprised of a single thin, pliable synthetic film sheet, and which is hermetically closed by welding along three edges of its perimeter while on its remaining edge at its base there is provided, integral with the sheet, a bellows facing towards the interior of the casing, said bellows having a central zone, of which there branches a nozzle set sealed to and extending from said central zone, each nozzle being provided with a resilient sealing member;
- and means along said three welded edges for supporting said casing.
