Aseptium & 4c Engineering joined forces meet the urgent need for PPE producing face shields for ICU team at Raigmore, kicking off Project Corran.

Corran is Gaelic for "crescent" - the shape the face shield adopts once it's being worn. Being based in the Scottish Highlands this seemed like an appropriate choice.

Solasta House, location of Nexus and 4C, and Aseptium, co-reators of Project Corran


Both 4c Engineering and Aseptium are based in Highland and Islands Enterprise's (HIE's) Nexus collaborative workspace on Inverness Campus. LifeScan have a large facility forming part of the wider Life Science campus on the other side of the A9, adjacent to Raigmore Hospital.

In Nexus, we work alongside a number of other young companies in the life science and technology sectors. The open layout of the offices encourages discussion between companies which fosters a positive and collaborative atmosphere. We often turn to each other for advice, even on the simplest of things like identifying a reliable component supplier or recommending a source of information.

As the COVID-19 outbreak grew and spread out from China we started to become aware of potential shortages or areas where assistance was being sought from private companies. Firstly, there was the much publicised call for ventilators which then widened to ask for help with more general PPE. 

We formed a small working group alongside some local engineers to see if there was anything we could do to help.

With the culture of innovation and rapid prototyping we're so used to working in it would have felt strange not to do this! We soon identified a need for additional face shields to protect workers from liquids or droplets which were sprayed, coughed or sneezed towards them. 

At this point the group widened, getting input from HIE and building on some links we have within NHS Scotland (Raigmore hospital is just across the A9 from the campus). We got in touch with people here, to make sure that we weren't wasting our efforts and that what we were working on was something they actually needed (great learning note for any design project - get as much input from the end users as possible!). 

By working together we've managed to access supply chain knowledge, fabrication tools and equipment, design skills and user feedback far beyond what a single company could achieve alone. Working together doesn't stop here which is why we've chosen to make this design open source and expand the team to include you and anyone else who wants to help.
