This demo shows OpenBreath's prototype ventilator in Pressure and Volume Control. Every five breaths, parameters are changed to show the dynamic response of the device.
WHAT :
The OpenBreath project aims at addressing the lack of ventilators in IC units all over the world, caused by the Covid 19 Pandemic.
The OpenBreath team is developing a fully functional ventilator, offering all the fundamental ventilatory tasks of a traditional hospital respirator at significant lower price and production time.
Main Features :
- Innovative design based on the automatization of a bag-valve-mask (BVM)
- Quickly producible with "off-the-shelf" parts
- Extremely low cost
- Both invasive and non-invasive assisted ventilation: PEEP, SIMV, CPAP modes
- Aims at compliance with the BS EN 80601-2-12:2020 standard
- Connected device and live interface:
- Sensors: pressure, flowrate
- Provides blood oxygenation rate and heart rate (nice to have)
- Will send alerts and updates in real-time directly to healthcare professionals
HOW :
The device only needs electricity connection to be fully operative, and has been designed for industrial manufacture. It is made of sheet metal parts and off-the-shelf components in order to be accessible and buildable anywhere in the world.
The project is aiming at implementing the most important Intensive and Sub-Intensive care ventilatory modalities. These include mandatory ventilation functions such as Pressure and Volume Control, which enables the respiration of sedated patients, and more sophisticated assisted functions like SIMV, which is employed to slowly adapt the patient to spontaneous breathing again. In addition, this ventilator is designed to be redundant on both the mechanics and the electronic circuits, so that it can be failsafe. Specifically, if one of the two motors fails, the other one will increase its speed to compensate for the fault, while triggering an alarm.
The ventilator relies on the automation of a Bag-Valve-Mask (BVM) as its pneumatic component. This means that the device can be effective even where pressurized medical air is not readily available, such as in field hospitals or less-developed countries where medical air limited.
WHY :
The project was born in the context of the current emergency but it can represent a significant resource for other pandemic scenarios or natural disasters. This very flexible and scalable solution presented here can be employed indifferently in many settings.
