I'm Danielle Zurovcic, a PhD Candidate
in mechanical engineering at MIT and I
designed a simplified, negative pressure wound therapy device
for wounds in the third world.
Specifically, we went to Haiti during the disaster relief
effort to apply the device to applicable wounds.
Let me demonstrate the device on a clean area of skin,
such as the ankle, a typical location of diabetic ulcers
and impact wounds in Haiti.
First, you dress the wound with a gauze or sponge, or whatever
you may have in hand.
Then, insert your drainage tube.
And then take whatever occlusive dressing you have in hand,
and cover both the drainage tube and the gauze.
Seal down you're dressing, making it airtight.
Then take the device, and compress device,
which is the pump.
Make sure that your plug is inserted airtight.
And now your pump is set, which will
pull on your wound dressing for 24 hours a day,
seven days a week.
And your dressing is now hard, because it does not have
any air in it and has a vacuum.
