MICROFLUIDIC MIXERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17826943 titled 'MICROFLUIDIC MIXERS

Simplified Explanation

The abstract describes an example microfluidic mixer design.

• The mixer includes an inlet channel, a fluid splitting channel, a fluid recombining channel, and an outlet channel.
• The fluid splitting channel has an overpass channel and an underpass channel, which overlap at their downstream ends.
• The fluid recombining channel has an angled surface that helps mix the fluids.
• The outlet channel is connected downstream from the fluid recombining channel.
• The design aims to efficiently mix fluids in a microfluidic system.

Original Abstract Submitted

An example microfluidic mixer can include an inlet microfluidic channel portion and a fluid splitting channel portion including an overpass microfluidic channel to receive fluid from a first side of the inlet microfluidic channel portion and an underpass microfluidic channel to receive fluid from a second side of the inlet microfluidic channel portion, where the underpass microfluidic channel extends under the overpass microfluidic channel such that the channels overlap at their respective downstream ends. A fluid recombining channel portion is downstream of the fluid splitting portion and includes an angled recombining surface having an acute angle with respect to a direction of fluid flow, where the angled recombining surface is between the downstream ends of the overpass and underpass microfluidic channels. An outlet microfluidic channel portion is fluidly connected downstream from the fluid recombining channel portion.
