Abstract
Systems and methods for forming a microfluidic device are disclosed. Microfluidic channels are formed into a substrate. The substrate can be formed into a roll to define a plurality of layers and bonded to itself. The substrate can be at least partly positioned within a housing.
Claims28
A system comprising:
- a laser engraver configured to form a plurality of channels into a substrate, the substrate having a first surface and a second surface opposite the first surface;
- a take-up roll configured to roll the substrate with the plurality of channels formed therein;
- and
- a bonder that is configured to bond a portion of the first surface of the substrate to an adjacent portion of the second surface of the substrate.

A method of making a microfluidic gas exchanger, the method comprising:
- forming a plurality of channels into a substrate;
- winding the substrate onto a take-up roll;
- and
- bonding a first surface of a first portion of the substrate to a second surface of a second portion of the substrate that is adjacent the first portion along a radial axis.
