For healthcare drug delivery devices like infusion pumps or insulin pumps, exact dosing is crucial.
Renesas’ winning combination of drug delivery dosing motors with ISO12207 software provides precision. Motors are typically three-phase brushless DC motors (BLDC) types with a few watts (e.g., using 12 V). For flow sensing, a factory-calibrated sensor or custom sensors may be used. Bluetooth® communication may also be needed to provide an up-to-date GUI via smartphone and additional interfaces, like Ethernet or a (medical-grade) isolated USB. Some end products may also require an uninterrupted power supply (e.g. use of Li-ion cells).
Software following the ISO12207 standard can dramatically reduce time-to-market and development costs. Renesas provides this through its Synergy software package.
