The HDVent EmergencyVentilator System is a low-cost, emergency resuscitator for patients suffering from COVID-19.
The HDVent system was developed by a group of technicians, physicists, anesthesiologists from Heidelberg University, and IT professionals from Rommelag iLabs in Karlsruhe, in March 2020 to avoid a local emergency situation caused by coronavirus disease.
HDVent architecture
The air supply consists of an Ambubag connected to the intubated patient + standard valves.
On-board sensors measure the pressure and the in- and outflow rates near the patient mouth piece.
The Ambu is compressed between two mechanical arms shaped to reduce wear and tear effects.
The user interface provides easy access to and control over the ventilation parameters .
All electronics are implemented on a custom-made PC board mounted to the front panel.
A monitoring unit based on a Raspberry Pi computer displays volume and pressure time traces, settings and alarms.
