Microfluidic Delivery of High Viscosity Liquids Using Piezoelectric Micropumps for Subcutaneous Drug Infusion Applications.
IEEE Open J Eng Med Biol
January 2024
Article Synopsis
- Auto-injectors typically require refrigeration, and if not warmed, they may not deliver the full drug dose due to their mechanical design not compensating for changes in drug viscosity.
- A new piezoelectric micro diaphragm pump has been developed to effectively deliver high-viscosity liquids (up to 25 mPa·s) using a specialized design, achieving fluid pressures of up to 368 kPa.
- Experimental results show that this micropump can produce maximum flow rates of 2 mL/min through 27G needles, paving the way for more advanced auto-injectors capable of handling thick medications.
