Abstract:
1. A method of manufacturing a valve from a plurality of flexible polymer layers, the method comprising steps of: constructing a first sub-assembly by forming a first substrate weld between a first valve layer and a first substrate layer, said first valve layer having an inlet portion and an outlet portion; aligning said first sub-assembly with a second element such that said first valve layer is positioned between said first substrate layer and said second element; and bonding said first valve layer with said second element by forming a pair of spaced channel welds between said first valve layer and said second element, said channel welds defining a channel located between said first valve layer and said second element and between said channel welds, said channel having an inlet adjacent to said inlet portion and an outlet adjacent to said outlet portion.
