Abstract:
1. A valve structure of a fluid delivery and analysis system, wherein said valve structure is comprised of an upper substrate, a lower substrate and an intermediate layer wherein said intermediate layer is comprised of at least one opening wherein said at least one opening extends from an upper surface of said intermediate layer through to a lower surface of said intermediate layer and at least one indented well wherein said at least one indented well has an opening end at said upper surface of said intermediate layer and a closed end at said lower surface of said intermediate layer or said at least one indented well has an opening end at said lower surface of said intermediate layer and a closed end at said upper surface of said intermediate layer wherein a first touch point is provided between said upper substrate and said intermediate layer and a second touch point is provided between said lower substrate and said intermediate layer wherein said first touch point and said second touch point are offset to create a torque when said intermediate layer is compressed between said upper substrate and said lower substrate wherein said torque deforms said intermediate layer in the direction of said at least one indented well.
