The Wound-Pump, provides inexpensive, portable, sustainable Negative Pressure Wound Therapy (NPWT) in all environments around the world.


Many medical techniques are not readily available in the third world, in the military, for disaster relief, and in domestic environments. This can be due to a lack of electricity, high cost, and other economical constraints. For these reasons, a successful, chronic wound treatment, known as negative pressure wound therapy (NPWT), has not been readily used, although many patients would benefit: approximately 55 million patients in the third world alone. Aiming to expand this therapy, the viability of an inexpensive, purely mechanical simplified negative pressure wound therapy (sNPWT) system is explored in this project. The Wound-Pump, a bellows pump, is chosen for the final design, and is analyzed in preparation for manufacture. An air leak detection system, along with proper dressing techniques, is defined. Once sNPWT is proven to be viable, it is approved by the Internal Review Board (IRB) at Massachusetts General Hospital (MGH) for initial clinical trials at the Shriners Bum Hospital in Boston, Massachusetts. Its high impact and sustainability further its application in resource poor settings (Rwanda, Africa and Port-au-Prince, Haiti) by the Wound Care Team. The Wound-Pump is the first device in our mission to improve world healthcare through smart design.
