PRESENTATION RENDERS<br />
Seal<br />
A thermoplastic seal<br />
can be heated prior<br />
to being fitted which<br />
then moulds to the<br />
users face.<br />
One Pull<br />
The bottom strap<br />
has a single pull<br />
mechanism which<br />
tightens around the<br />
chin.<br />
Valves<br />
Valves on either side<br />
of the mask release<br />
the excess pressure<br />
when exhaling.<br />
Metal Pinch-strap<br />
User research showed many users preferred<br />
masks with pinch-straps, saying the often<br />
make the mask feel more secure, it also<br />
helps keep the shape of the thermoplastic<br />
after forming<br />
Straps<br />
Window<br />
A clear PVC window<br />
aids communication<br />
between user and a<br />
colleague or patient.<br />
Nose Strip<br />
The metal nose strip<br />
flexes to hold the<br />
masks shape, and is<br />
a form of reassurance<br />
for the user.<br />
Thermoplastic Inserts<br />
Thermoplastic inserts sewn in around the<br />
mask (in the blue area) when heated are<br />
easily moulded to a large variety of faces<br />
The straps are stapled into the masks, run<br />
behind the ear and through a channel at the<br />
bottom of the mask to the toggle.<br />
So the strap does not have to pass through<br />
a seal the channel is outside the “clean” area<br />
created by the mask<br />
62°C<br />
Exhale Vents<br />
When the user breaths out these vents allow<br />
the humid air to leave the sealed area inside the<br />
mask, reducing discomfort.<br />
Cord Lock<br />
The pull-down cord lock allows the user to<br />
evenly tighten the mask straps in one easy<br />
movement.<br />
