Abstract:
1. A method of delivering a fluid from a fluid source, comprising the steps of: providing a pump comprising a microfluidic substrate having a first capping module stacked thereon to form a pump chamber, a second capping module stacked thereon to form an inlet fluid regulating device into the pump chamber and a third capping module stacked thereon to form an outlet fluid regulating device from the pump chamber, each capping module defining a chamber in communication with an inlet channel and an outlet channel formed in the microfluidic substrate and having a flexible membrane forming a side wall of the chamber to selectively block fluid flow through the chamber; and an external actuator disposed adjacent to and in contact with the membrane of at least one of the capping modules selectively deflecting the membrane to pump fluid from the fluid source through the infusion pump.
