Abstract:
1. A fluid coupler comprising plural film layers disposed on a substrate top surface of an included substrate, the plural film layers disposed with respect to one another to define a top film layer and a bottom film layer, the top film layer defining a film layer top surface and the bottom film layer defining a film layer bottom surface, each film layer having two opposing film layer sides with a corresponding film layer thickness or spacing therebetween, each film layer further having one or more regions that are devoid of film material, each film layer thus forming one or more cavities with corresponding cavity openings on both of its film layer sides, each film layer having one or more of its cavities disposed to provide fluid coupling with its respective adjacent film layer or with both of its respective adjacent film layers, as the case may be, the plural film layers disposed to form at least one film layer traverse channel coupling at least one cavity opening in the film layer top surface with at least one cavity opening in the film layer bottom surface, the plural film layers forming one or more film layer lateral channels, each film layer lateral channel coupling a corresponding group of cavity openings in the film layer top surface, the substrate comprising at least one substrate channel coupling at least one substrate opening in the substrate top surface with one or more additional substrate openings comprised in one or more substrate surfaces of an included substrate front surface, substrate back surface, substrate left side surface, substrate right side surface and substrate bottom surface, the plural film layers disposed such that at least one film layer traverse channel fluidly couples with at least one substrate channel, comprising the film layer traverse channel coupling exactly one cavity opening in the film layer top surface with exactly one cavity opening in the film layer bottom surface the substrate channel coupling exactly one substrate opening in the substrate top surface with exactly one additional substrate opening comprised in the substrate front surface.
