There are several types of ‘smart-bandage’ under development particularly aimed towards chronic and non-healing wounds. The majority of these strategies rely on the topical and passive delivery of therapeutics, which are shown to have low success rates and ineffectiveness. A new strategy is needed to avoid the lack of vascularization in the wound surface and incorporate drug delivery, oxygenation, and vacuum therapy in one integrated platform.

Technology Overview

The micropump utilizes two elastic membranes attached to magnets in two chambers for the pump and the valve. It also has a modular design that is employed to allow for easy assembly and attachment to a microfluidic chip. The micropump’s entire housing is 3D printed by fused deposition modelling to allow for ease of fabrication and flexible adoption to microfluidic applications.
