Solution Overview & Benefits

Information updated: May 14th 2020

This is an Air Purifying Respirator (PAPR) mask. CroResp comprises a respirator with eye protection made from a diving mask, adapter and virus filter. The respirator is designed for personal use at the discretion of medical professionals in the case of lack of certified and tested protective equipment. The respirator is intended to protect the airways and eyes of medical personnel, especially those who carry out procedures where aerosol is generated by coronavirus infected patients.

History & Development

This project was inspired by the pioneering efforts of two groups from Italy and the United States. The Italian company Isinnova, in collaboration with Dr. Renato Favero of Gardona Val Trompia Hospital in Italy, made a 3D printed replacement ventilator valve used to treat patients, and then a non-invasive ventilation mask based on the Decathlon diving mask. Non-invasive ventilation is currently widely used in Italian hospitals to support the breathing of patients who are in a serious (but not critical) condition and do not require immediate intubation and invasive ventilation. At the same time, a group from the United States (Boston Children’s Hospital) has proposed an innovative way of making a device that, in the absence of PPE, can replace a respirator for the personal protection of medical personnel. They suggested and presented a way to make a respirator out of an anesthetic mask, a viral filter and elastic bands, parts that should still be widely available. CroResp is a combination of the above methods - the Italian idea of a diving mask with a customized adaptor and the American virus filter connected to an adapter created by 3D printing.
