Abstract :
The first check valve featuring dual regulation of in-plane flow and heat-shrink tubing packaging is presented. This modular design is optimized for integration into low-profile fluidic devices requiring flow control, such as drug delivery devices. Theoretical and finite-element-modeling (FEM) analyses were performed to guide valve design and these results were confirmed experimentally. The valve regulates flow between 150-900 mmHg (20-120 kPa) and withstands > 500 mmHg (66.7 kPa) of reverse pressure. The heat-shrink packaging scheme does not require adhesives and is extremely robust (>2000 mmHg without leakage).
