Professors and lab engineers from Texas A&M University at Qatar mobilized their resources to develop face shields, valves, and other tools that would help fight the virus. One such prototype was that of a snorkelling mask that could be converted into a ventilator using just an adapter and being plugged into ventilating machines at hospitals, or used as a substitute for the widely used N-95 masks.

A startup company in Italy first began to apply this model – using snorkelling masks manufactured by Decathlon, a sporting goods company and modifying them to be plugged into ventilators. Using the open-source information available online, Dr. Marwan Khraisheh and Dr. Yasser Al-Hamidi of Texas A&M University at Qatar’s (TAMUQ’s) Mechanical Engineering Program led the efforts to design and develop similar versions for Qatar. Qatar Foundation Research, Development and Innovation arranged for the masks to be donated by Decathlon to the engineering team for modification.

The team at the Qatar Foundation partner university began by designing a better-engineered version of the open-source concept available and used the fabricating facilities and 3D printers available in their laboratories. The idea was to repurpose these commercially available snorkelling masks by connecting them to adapters/valves to be used as non-invasive ventilators.

For patients with respiratory difficulties, a ventilation procedure called intubation is typically employed, which involves inserting a tube into the trachea. Using the adapter designed in-house connected to a snorkelling mask, the invasive procedure can be omitted entirely.

Additionally, these masks feature a filter and a PEEP valve that the team at TAMUQ worked to modify, to ensure little to no leakage of contaminated air once worn by a patient with COVID-19, and to keep positive pressure inside lungs to keep lungs from collapsing. This could significantly reduce the risk to healthcare workers treating COVID-19 patients. It would also make it a good option for healthcare workers to use as it dials down the risk of contracting the virus.

Having already delivered hundreds of modified face shields to both Qatar Foundation and Qatar Red Crescent, TAMUQ has also delivered prototypes of the snorkelling mask adapters to Hamad Medical Corporation, should there be a need to use them. Other innovations in the works include isolation chambers for patients and hands-free door openers for the general public now that countries are opening up again.
