Completed visors for an NHS COVID-19 ward in Lincolnshire
This week we sent our first completed protective visors for use in a NHS COVID-19 ward in Lincolnshire. We 3D printed the headbands in our Studio. They were then cleaned manually by filing to take off rough edges and imperfections. The 300mg acetate is to be installed before use. This is the heaviest we could find so it can be disinfected every evening and re-used the next day. We didn’t install them in the frames as we were worried they would be damaged during transport, only one was installed as an example.To install the acetate it just needs to be introduced by the corner of the acetate into the small gap between the two layers of the 3D printed headband until the acetate is coming out from the other side. The external ring of the headband is designed to be flexible in order to slide the acetate smoothly between the two layers.The elastic band is 2” wide in order to be comfortable on the head over prolonged use. We have secured it on both sides with simple knots so each individual can adjust it to suit. When we had it tested we found this to be critical to comfort, if it is too tight it will hurt, if too loose it is not secure, so it is critical it is just right.This is our little contribution and to show admiration and appreciation for the NHS operatives working in these difficult times and conditions, THANK YOU.
