Bag for medical use and apparatus for the production of same

摘要

An apparatus for the supply of bags for medical use contains an extruding machine (1), a device (3) for forming an extruded tube (4), a device (3a) for the supply of mouthpieces (13) and a device (11) for the horizontal transportation of the extruded tube (4). A sterile-air supply conduit (5), a supply conduit (6) for a medical fluid, an air-recovery conduit (7) and a second sterile-air supply conduit (6b) arranged in the abovementioned supply conduit (6) for the medical fluid are guided through the shape (2) of the device (3) for forming the extruded tube (4). A material is extruded in tube form by the forming device and mouthpieces (13) are welded to the outer surface region of the extruded tube (4) in the melted state. The extruded tube (4) is pressed at intervals through the forming device (3), in order to produce melted regions (9, 9a) which have fluid passages (10). Sterile air is supplied into the interior of the extruded tube (4), and the shape of the extruded tube is maintained by means of the pressure of the sterile air. The volatile component contained in the constituent material is recovered by means of the recovery conduit (7). Also, a medical fluid is [lacuna] by the supply conduit (6) for the medical fluid into the interior of the chambers (4a) [lacuna] Original abstract incomplete.
