Renesas has introduced an open-source ventilator system reference design that customers can use to swiftly design ready-to-assemble boards for medical ventilators.
Many regions are experiencing a critical shortage of ventilators as COVID-19 infections continue to rise and hospital demand exceeds supply.
Renesas’ engineers have followed several open-source ventilator designs, including the Medtronic PB560, to come up with an easy to assemble three board ventilator design.
The reference design uses 20 Renesas ICs, consisting of MCU, PMICs, and analogue ICs that address many of the ventilator’s signal chain electrical functions.
The system design implements a sensor board, a motor control board, and features Bluetooth connectivity that allows medical professionals to monitor several patients simultaneously via a tablet or other mobile device.
Each board has an MCU to control its specific task while monitoring the status of the connecting board. The ventilator solution also provides a system of checks and balances to enable regulatory approval and provide patient safety.
