Microfluidic device
First Claim
1. A microfluidic device, comprising:
- a microchannel having an interior bounded by a side wall, an inlet, a switching region, and a plurality of outlet channels downstream of the switching region, the microchannel formed in a microfluidic chip substrate and configured to accommodate a flow of liquid through the microchannel;
a valve operatively coupled to the switching region comprising a sealed reservoir, a side passage extending between the reservoir and the interior of the microchannel via an aperture in the side wall, the side passage configured to accommodate a volume of liquid between the interior of the microchannel and the reservoir; and
an actuator integrated in the microfluidic chip, the actuator configured to increase an internal pressure of the reservoir and move at least a portion of the volume of the liquid from the side passage into the microchannel to deflect a portion of the liquid flowing through the microchannel.

Abstract
A microfluidic device includes a microchannel having an interior bounded by a side wall, an inlet, a switching region, and a plurality of outlet channels downstream of the switching region. The microchannel is formed in a microfluidic chip substrate and configured to accommodate a flow of liquid through the microchannel. The microfluidic device includes a valve operatively coupled to the switching region comprising a sealed reservoir. A side passage extends between the reservoir and the interior of the microchannel via an aperture in the side wall and is configured to accommodate a volume of liquid between the interior of the microchannel and the reservoir. The microfluidic device includes an actuator integrated into the microfluidic chip and configured to increase an internal pressure of the reservoir and move at least a portion of the volume of the liquid from the side passage into the microchannel to deflect a portion of the liquid flowing through the microchannel.
