Drug Delivery with ISO 12207 Software

For healthcare drug delivery devices, like infusion pumps or insulin pumps, exact dosing is crucial. Thus, measurements of real drug delivery amounts plus exact control of dosing motors are required. Motors are typically three-phase BLDC types with a few watts (e.g. using 12V). 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. using 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.

System Benefits:

• Supports infusion pumps and insulin pumps
• Motor control for brushless DC motors (BLDC) or permanent magnet synchronous motors (PMSM) with analog or hall sensors/encoders, optional gear (also with high gear ratio)
• Flow measurement options: Integrated sensor or MCU-integrated analog front-end (AFE) for custom sensor setup
• Communication: Bluetooth 5, Wi-Fi, Ethernet (e.g. for infusion pumps), and multiple serial interfaces for optional LTE-NB, isolated USB I/F, etc.
• HMI: LCD (for infusion pump) and touch and/or gesture control, also for a sterile environment
• Battery management (e.g. optional 2x Li-ion cell for uninterrupted power supply)
• Synergy Software Package that follows ISO/IEC/IEEE 12207 standards
