FLUID CONTROL DEVICE AND METHOD OF MANUFACTURE

摘要

A fluid control device comprises a first polymer layer having a top surface, a bottom surface and a void extending through the first polymer layer and having an opening in at least the bottom surface; and a second polymer layer forming a membrane across the void in the first polymer layer. A third polymer layer having a top surface and a bottom surface may also be provided, such that the second polymer layer is disposed between the first and third polymer layers. The bottom surface of the first polymer layer and the top surface of the third polymer layer are in contacting arrangement around at least a portion of the perimeter of the second polymer layer. The fluid control device may be formed by injection-moulding a first polymer layer and subsequently injection-overmoulding a second polymer layer onto at least a portion of the first polymer layer to form a seal between the membrane and the first polymer layer.
