dc.description.abstract | Highly popular insulin patch pumps have in-built non-removable batteries. These batteries are routinely disposed of together with the used pumps as medical waste and end up in landfills. This is an environmental contamination conundrum by design. To address this issue, we proposed a self-powered patch pump that uses a biodegradable superabsorbent polymer (SAP) instead of a battery as a power source to drive the infusion. Continuous infusion rates from 6.1 mu L min(-1) to 49.1 mu L min(-1) were achieved. Together with valve throttling, basal and bolus infusion rates of similar to 10 mu L h(-1) (1 U h(-1)) and 100 mu L (10 U) in similar to 11 min could also be implemented for glycemic control. The generated pressure at similar to 0.7 psi is also adequate for infusion as it exceeded an adult's maximum peripheral venous pressure of 0.6 psi. Given the current number of patch pump users, the proposed design could prevent similar to 100 000 used batteries from entering the medical waste stream and landfill daily. Most importantly, this work highlights the possibility of addressing environmental contamination without compromising on healthcare standards by using SAP as an alternative means of energy storage. | - |
