Basic Study of Micro-Pumps for Medication Driven by Chemical Reactions

We have developed and evaluated a prototype micro-pump for a new form of medication that is driven by a chemical reaction. The chemical reaction between citric acid and sodium bicarbonate produces carbon dioxide, the pressure of which pushes the medication out. This mi-cropump is smaller in size than conventional diaphragm-type micropumps and is suitable for swallowing.

Automated summary

We have created and tested a prototype micro-pump that relies on a chemical reaction to drive medication delivery. The reaction between citric acid and sodium bicarbonate generates carbon dioxide, which then pushes the medication out. This smaller alternative to diaphragm-type micropumps can be easily swallowed.
