Multichannel pumps and applications of same
Abstract
A push-pull micropump includes one or more pairs of channels configured to transfer one or more fluids, each channel pair having an aspiration channel and an injection channel; and an actuator configured to engage the one or more pairs of channels, wherein the actuator comprises a plurality of rolling members and a driving member configured such that when the driving member rotates, the plurality of rolling members rolls along the one or more pairs of channels to cause individually the one or more fluids to transfer through each channel pair simultaneously at different flowrates or the same flowrate, depending upon actuated lengths of the aspiration and injection channels of each channel pair, wherein an actuated length of a channel is defined by a length of the channel along which the plurality of rolling members rolls during a full rotation of the driving member.
