Gallery: $3 Healing Device Speeds Up Wound Treatment

 

Fact: the healing process can be sped up dramatically by applying suction (AKA negative pressure) to bandage-covered open wounds. No one knows why this works, but doctors think it might keep wounds clean by drawing fluid and bacteria elsewhere. Whatever the case, negative pressure system dressings can be kept in place for days at a time, all while speeding up healing. Up until now, the $100 per day rental systems have been out of reach for the developing world, but MIT student Danielle Zurovcik recently developed a negative pressure pump that costs just $3 to build.

    I have applied thousands of NPWT treatments and I can say this “inexpensive” treatment will require daily drsg changes = more pain. Standard KCI NPWT can be done every three days. The inexpensive treatment is also a constant pressure with limited drainage collection. studies have shown intermittent pressure is best. I have had paients with high draining wounds and by the picture above that dressing would never stay in place.

    I had to use one of those suction devices after I developed a leg infection from surgery. It was expensive, loud, uncomfortable and required frequent charging. It boggles my mind that there was a $3 solution that seems superior but these big companies never thought of it. I hope this makes life easier for folks around the world.

    What are they thinking? Probably of ways to screw people out of more money.

    This design warms my heart and it proves that when there is a will, there is a way. The companies that charge $100 / day for a similar device probably never bother to invent a dramatically more affordable solution. I wonder what those companies are thinking now.
