Renesas Electronics Corporation has introduced a new open-source ventilator system reference design that customers can use to swiftly design ready-to-assemble boards for medical ventilators. As COVID-19 infections continue to rise and hospital demand exceeds supply, many regions are experiencing a critical shortage of ventilators.

Chris Allexandre, senior vice president, IoT, and infrastructure business unit at Renesas said, “Renesas’ engineers have created a ventilator system reference design to address the challenges our global community faces as we fight the COVID-19 pandemic. Leveraging our broad product portfolio and system design expertise, we are enabling customers to accelerate their development of medical ventilator systems capable of operating in a home or hospital environment.”

Portable and can be used with or without gas tanks

Renesas’ engineers have followed several open-source ventilator designs. This includes the Medtronic PB560 to come up with an easy -to -assemble three board ventilator design. It controls the tidal volume and mixture of gas delivered to the patient while monitoring the patient’s status. The ventilator is portable and can be used with or without gas tanks. A humidifier can be connected to the ventilator’s intake path to make it more comfortable to be connected for long durations

Bluetooth connectivity

The reference design uses 20 Renesas ICs. It consists of microcontroller (MCU), power, and analog ICs that address many of the ventilator’s signal chain electrical functions. This system also incorporates a sensor board, a motor control board, and features Bluetooth connectivity. It will allow medical professionals to monitor several patients simultaneously through a tablet or other mobile device. Each board has a microcontroller (MCU) to control its specific task while monitoring the status of the connecting board. It also provides a system of checks and balances to help in regulatory approval and provide patient safety.
