Patent ID: 8096784

Claim:
A bi-directional continuous peristaltic micro-pump, comprising: a substrate; an actuating mechanism, connecting with said substrate, which comprises: a first slanted membrane, the thickness of which increases progressively from left to right during a state of rest, wherein a first chamber is formed between said first slanted membrane and said substrate, arranged such that an increase in the internal pressure of said first chamber causes said first slanted membrane to bulge from left to right into an expanded state; and a second slanted membrane, the thickness of which decreases progressively from left to right during a state of rest, located to said first slanted membrane's right side and parallel to said first slanted membrane with a space between the two membranes, wherein a second chamber is formed between said second slanted membrane and said substrate, arranged such that an increase in the internal pressure of said second chamber causes said second slanted membrane to bulge from right to left into an expanded state; and a fluid channel for receiving a working fluid, said fluid channel arranged across said first slanted membrane and said second slanted membrane, arranged such that bulging of said first slanted membrane when said second slanted membrane is in a state of rest forces said working fluid to flow to the right.
