Modular PAPR – Modular filtered air supply for the protection of medical personnel and for respiratory support of patients

In order to realize the project, competences in additive manufacturing and rapid prototyping, medical engineering and membrane/filter technology were bundled at Fraunhofer IGB.

Medical staff in hospitals must be particularly protected against infection with the coronavirus SARS‑CoV‑2. In many places, protective equipment has already become scarce due to the rapid spread of the virus, so that disposable products had to be used several times.

In the anti‑corona project "PAPR", Fraunhofer IGB is therefore developing a modular and reusable powered air‑purifying respirator (PAPR), which provides filtered – virus‑free – breathing air. To protect COVID‑19 patients from secondary infections and to reduce the viral load in the room air, the second stage also filters the wearer's exhaust air. In the third development stage, our PAPR enables non-invasive individual respiratory support for patients with mild respiratory distress who do not yet require full ventilation.

The key aspects in the development of PAPR are its modular design and the use of components that are also available in large quantities in the corona crisis and were not originally intended for medical purposes. For the implementation, the IGB is bundling competences from additive manufacturing, medical technology and membrane technology.
