Here you can see our objectives. Use of approved medical equipment, component manufacturing by 3D printing, use of commercially available small electric motors in combination with standard accessories, easy assembly anywhere in the world and simple user interface:

Free available

Standard Ambu-Bags available worldwide can be used for manual ventilation.

3D printing components

Maximum compatibility by using extensive 3D printing elements.

Electric motor incl. control elements

Use of simple electric motors and Arduino components with freely accessible software for control.

Standard accessories

Small and assembly parts from commercial stocks.


Simple assembly according to intuitive instructions.


Research and development of a concept for self-construction of automatic, freely available, cost-effective ventilators.

The international project "LUCSY" lung care system is designed regionally and can be applied worldwide

The project is driven by members of the University of Applied Sciences Würzburg-Schweinfurt in the wake of the COVID 19 pandemic. On the initiative of the Brazilian student Gustavo Pinto, they are currently realizing his idea of a low-cost "ventilator" that can be used worldwide and manufactured with local resources. It is being developed for situations in which closed ventilation systems are not (no longer) available for use in the care of COVID-19 patients or other situations requiring ventilation.

The international project team around the professors Dr.-Ing. Volker Bräutigam and Dr. Uwe Sponholz, together with the student assistants Gustavo Pinto, Philip Schömig and Daniel Blümm, as well as the technical officer Josef Zenker and the scientific assistant Dipl.-Ing. Maximilian Rosilius, develop different concepts for devices to "automate" a resuscitator.  

Out of five principles and a total of seven versions, three concepts, the belt or belt drive, the crank disk with eccentric and the so-called waffle iron or shell principle,  have emerged as the most promising. [ to the course of the project ]


FHWS:vs:Virus is a non-profit, nonprofit project

All results of the concept are made available free of charge as component parts lists, plans, drawings and program codes and are to be explicitly distributed, further processed and used. The device is to be designed in such a way that a standard "ambu-bag" together with an electric motor including control and power electronics, 3D printed components and accessories can be assembled into an automated ventilator anywhere on earth. Should the worst case scenario occur and the available demand for ventilators no longer be met, the capacities can be temporarily increased.
