Anordnung zum Verabreichen einer medizinischen Flüssigkeit

摘要

The bag (20), for the administration of a medical fluid, has four overlaid film layers (22,22';23,23'). Both the outer film layers (23,23') extend over the band width of the inner layers (22,22'). The inner layers (22,22') are welded to the outer layers (23,23') to form the two chambers (25,26) in the bag (20). The outer layers (23,23') are welded together at their outer edges to form a third chamber (30) for the delivery tubing. Or the bag (20) is formed by three overlaid layers welded together, with a common dividing wall for the two chambers (25,26) formed by the inner layer. The third chamber (30) holds the delivery tubing system (21) in a sterile packaging. The tubing has an outflow tube (36) from the feed tube (31), with its free end welded into the closing seam (24') defining the second chamber (26).
