Instructional video for sewing the Olson mask (COVID-19)

I just wanted to take a moment to talk
about the process that this is not a
replacement for personal protective
equipment it’s an alternative in case
the event happens that we should run low
on supply this is not in no way
replacing the the current process that
we have in place now it’s just an
alternative in a something that we could
possibly use if we need to hi everyone
my name is rose hedges and I’m the
nursing research and innovation
coordinator here at st. Luke’s Hospital
my name is Clayton Skousen I am the
fabrication fellow and generate the
makerspace here at the hospital so today
we’re going to be talking about how to
create the Olsson mask that we’ve
designed to be able to help keep keep
our clinicians safe as well as it can be
used in the public so the first step is
to be able to take some cotton fabric
I’m a blend will work but the lighter
the weight the better and then cut out
each piece and that’s the steps here so
Clayton here has everything set up and
ready for us to go so he’s going to sew
the first pieces together to kind of
show you how we’re going to be piecing
this together

do you think Owen do you think it takes
two so something like this I’m probably
about five ten minutes
so as he’s sewing that the next thing
that we’re going to be getting prepared
is our other pieces it’s going to be
important that we sew them together and
then we’ll put them together with
patterns touching so that way we can
then it invert them like a pillowcase
would act so he’s going to be grabbing
the next pieces here folding over the
seam and then sewing those down the
important piece of that is that we don’t
want any edges that can be fraying
fraying things like that are just going
to deteriorate as we have to wash them
so that’s why he’s folding these seams
show me how you pull that over Clinton
so I’m actually just doing just a
quarter inch and maybe it would probably
want to measure that and iron it down
I’m just kind of doing it quickly this
way but it is just a quarter inches long
Jenny that’s the same for the mouth
pieces as well as the cheek pieces which
is what I’m sewing
so now he’s going to do the same thing
with the mouthpieces
so the next step he’s going to be doing
is sewing the two mouth pieces together
so you’re just carefully lining them up
you can attend them I don’t think it’s
very necessary and for something like
this but you would like them to be more
so next he’s going to take the two
mouthpieces that he’s sewn together and
lay them next to where the dotted line
would be on your pattern with the cheek
because you’re kind of cleaning those up
what was tell me about how this pattern
was developed you worked with that I
mean it was just a solo effort you
worked with other people to collaborate
on this yeah so Clinton and I work
together with our maker health team
located and embossing and with their
resources as well so we did a lot of
literature review and looking at
filtration science and kind of what’s
going to be the most important thing
kind of bang for our buck idea and we’re
looking at being able to add our own
filter so there’s a lot of mask patterns
out there a lot of them are great and
yes they are going to help it is
definitely better than not having a mask
at all but we wanted to create something
that we could have that added protection
too and so that’s why we made it a
little bit more complex and some that
you’re actually seeing out there
floating around in society now because
we wanted to be able to add that filter
so as Clayton is cleaning up these last
pieces here to be able to sew the inside
piece which creates our pocket we’ll
show you kind of what that looks like
here yeah so we did a lot of mining for
data if you will in looking at kind of
what’s been studied out there before and
there’s some been some articles
published about lots of just home
materials that you can use for
filtrations and kind of what we were
looking at is kind of the micron level
and what the micron level of the virus
Kovan 19 and what we know for the n95
mask and we know that 0.3 microns is
kind of what the n95 mask is so we are
looking what is similar to that and we
found that actually vacuum bags like a
HEPA filter is about the same as that so
what we’re using you can purchase these
as well there’s lots of different HEPA
filters it’s the the HEPA filter fabric
is what we’re going to be using as our
filtration piece here it’s a great
question so there’s lots of things that
you can actually use you can like I said
the vacuum bag piece of it you can you
can buy them at the store you can
actually can look at micron filters you
can buy them on places like Amazon
things like that it’s going to work with
or without the filter it’s just at the

if somebody coughs in your face the
filter is going to give you a little bit
more added benefit it’s more about
having the filter piece and then the
seal which we’ll talk about here soon
okay so what I have here is the cheek
pieces and the mouth piece and I’ve had
them overlapped and just kind of you can
see how it blends into each other the
pattern has that blended spot so you put
it right on top of each other at that
point and actually I’m going to pin down
at this point mostly because there’s a
little bit more pieces hanging about you
can even pin it a little further in
won’t matter if it’s effective might use
a little is better and easier to do it
like so on both sides
what we’re going to be doing is we’re
gonna be creating the pouch the inside
of the mask and we’re only going to be
stitching right here where it’s
overlapping on the top and on the bottom
and we’re gonna leave this right here
open to create that pocket I’d like to
know all of the seam allowances that
I’ve been giving on all of these have
been 1/4 inch seam allowance which is
just for those who are unfamiliar with
selling terms is just how much distance
there is from the edge of the material
to where the actual stitch is going to
be going those stitches you can take out
okay so now we’re to fishing on the
other side
so now we’ve created the inside and the
outside of the mask and the outside
right here and on the inside of the mask
as well so this real quick and then what
we’re gonna do is we’re talking a
construct this similar to how pillowcase
is constructed
we’re just going to be sewing all the
way around and then turn you inside out
so as Clayton’s getting ready to sew
these two pieces together I’ll just
mention that again this is part of the
importance of having the non frayed
edges things that can unravel on us so
that was the purpose behind creating in
this pillowcase fashion
it was probably bit
all right yeah ball that around we’re
just going to stitch all the way around
and close it off
no just taking the needles out as we go
so as Clayton’s finishing up sewing
around this parameter here I can talk a
little bit about some of the tools that
we’re using to add into our mask
I know we discussed the filter filter
already but the other piece would be the
seal piece that we had mentioned so
there’s a couple things that I have kind
of laid out here that we can talk about
and helping create that seal you can use
things such as pipe cleaners you can use
things such as wax covered thread
anything that’s going to bend and hold
its shape is going to be a useful tool
and we’re going to put that at the top
kind of in the inside of that pocket to
help create that bridge of the nose
which gives you a tighter seal other
things that I’ve read about online that
people are using the top part of file
folder cabinets that go in your file
cabinets the bending metal piece
anything really that you can find that
kind of helps to create that seal is
going to help with these masks as for
our purposes and asking of the public if
you’re wanting to donate your time and
your materials I would just say that the
only thing that we’re requesting right
now is that you make this shape that
Clayton is making here we will take care
of the filter we will take care of
putting the elastic piece on for the ear
piece that holds it in place and we’ll
also take care of putting on the piece
that helps create that bridge and that
seal for protection so our general ask
really is just to create this pattern
here yes so now we have the mask made
can you show it to me a little bit clean
yep so that’s it’s all made inside out
right now
there’s little pockets that we created
and I have a total like croquet near
when I pull the side just in use with a
pencil or a pen just to kind of pop out
the corners a little bit better I think
it’s probably worth noting – it doesn’t
have to mean this is really a
nice-looking mask but it doesn’t have to
be super stylish – no absolutely not
definitely it could be one solid fabric
it could be the purpose of us using
multiple fabrics here so you could see
the different pieces and kind of
understand the way that we’re putting
those together it could be made out of
t-shirt fabric like I said breathable
the better because we’re putting a
filter inside of this we don’t want it a
heavyweight material but really anything
is going to help that pocket still that
you can put a filter in it so as well as
four different nose bridges they can
also be put inside so how do you I know
you said don’t worry about that aspect
but you will then put those nose bridges
in yourselves and I don’t nationally oh
you just pop it in there just play right
okay and what we have is we have wax
thread which will once it’s compressed
to the fabric it should hold in place
but we have some other options that
we’re looking at trying and how would
those stay in there do they just stand
they do I mean I suppose they’ve got a
little bit of tackiness with this okay
so won’t move around so much yep you
know people are wanting to be adding
their own elastics for their own use
we’re just using hair bands and really
only here is just to fold it right over
and what I would suggest is you’re
getting a safety pin and kind of
figuring out how far you need it to go
we added extra length on here so you can
fold it more or less for a different
size spaces find out what fits mark it
up and then just put a single stitch
right there
but if people want to even go that whole
nine yards so to speak and add two kind
of hair bands and stuff I mean just make
it a kind of yeah I would say still
right now I think that our our
preference would be that you would not
add the elastic piece to it right now
just because working with the clinicians
individually and what’s going to work
for them not that we’re going to measure
each patient or employee that comes in
the door but having multiple sizes that
we’ve kind of custom-made with that
would probably be the best
yeah absolutely so that’s another option
as well so you could insert a regular
surgical mask in here or you could wash
them and use them and like I said if you
don’t have the filter part it’s still
filtering out about 50% because it’s
cotton of the point three microns so
it’s still giving you quite a bit of
protection okay so now that we have our
finalized sewed mask we’re going to be
doing our last steps here and for those
of you in the community this is a step
that will take care of here at the
hospital but for those of you across the
globe that are wanting to do this on
your own communities these are the last
steps that you can do to make sure that
it’s a safe mask so we’re going to take
our point three micron filter and insert
it into the pocket here yep the hospital
provide these filters here and the help
we need from the community right now is
just sewing of the mask so making sure
that that gums up to the bridge of the
nose and down to the chin and it’s
opened up throughout this pocket lastly
what we’re going to be doing is adding
the skin safe double-sided adhesive tape
and this tape actually will help create
a seal around where your face is sealed
so that filter piece of it so I know
that this tape is clear and I’ll do my
best here to kind of create and mimic
that for you I’m so but basically using
the tape here we created across the
bridge of the nose you would kind of
create a seal that goes all around where
this white part is here so then when you
would put the mask on you would be able
to seal it across your face so be
putting it on in that fashion
so the piece with that that we found
that is most important we actually did a
fit test with these tests these masks
here and what we were finding is that
when we did this with the filter in
place without the adhesive tape it did
not pass the fit test however doing the
fit test with the adhesive tape added
the extra seal for us to be able to pass
that test
we recognized by no means this is a
scientific well studied process but we
did a study of one and we’re able to
find that with the adhesive tape it did
help so we’re looking forward to
studying this further and again I just
wanted to say thank you all for your
