摘要： A port is formed in a thermoplastic container wall by slitting the wall, inserting a thermoplastic tube through the slit, placing a mandrel in the tube, placing opposed dies defining a bore over the sheet and tube, and dielectrically heating the thermoplastic to fuse the tube and sheet. Preferably the bore defined by the dies is of a diameter slightly less than that of the tube, and has an enlarged central area which forms a thickened section of material over the slit.

摘要： A blood filtration device encapsulates a filter pad assembly Within a flexible housing. The filter pad assembly includes first and second filter media layers. A first heat and pressure sealed region integrally bonds the peripheries of the first and second media layers together. The flexible housing comprises a peripheral rim aligned with the first heat and pressure sealed region of the first media layer. A second heat and pressure sealed region, formed after the first heat and pressure sealed region, joins the rim of the flexible housing to the first heat and pressure sealed region, thereby forming a composite seal that encapsulates the filter pad assembly within the housing.
