New 3$ wound healing system

[flower]

Hmm does this look as good as it seems?

No one really knows why, but for an open wound, simply applying suction dramatically speeds healing times. (The theory is that the negative pressure draws bacteria out, and encourages circulation.) But for almost everyone, that treatment is out of reach--simply because the systems are expensive--rentals cost at least $100 a day and need to be recharged every six hours.

No more. Danielle Zurovcik, a doctoral student at MIT, has created a hand-powered suction-healing system that costs about $3. The device is composed of an airtight wound dressing, connected by a plastic tube to a cylinder with accordion-like folds. Squeezing it creates the suction, which lasts as long as there's no air leak. What's more, where regular dressings need to be replaced up to three times a day--a painful ordeal--the new cuff can be left on for several days.

Zurovcik originally intended to field-test the device in Rwanda, but then the Haiti Earthquake struck. At the request of Partners in Health, an NGO, she traveled to Haiti with 50 of the pumps.

Currently, Zurovcik is verifying the healing benefits of the device, and developing a new model that can be readily carried and concealed. The one technical hurdle that remains is ensuring the bandage seals tightly--but after that, the device could benefit a huge portion of the 50-60 million people in the developing world that suffer from acute or chronic wounds.

the logic seems reasonable but at the same time it seems more work than likely it is worth...

Looks good to me.

Having worked in an Operating Room, I can say that yes they do use something similar to this after surgery. Haven't seen one made like this though. My guess is this is a prototype and they will design something smaller and simpler. Maybe they already have since she created this in 2010.

the fact that it is simple and cheap could mean access by people who would never get access to the ones in the OR , perhaps?

It is accessible hospital wide actually, but a simple design and lower price is always better

It looks similar to the 'bellows suction' used to draw out blood from surgical sites. I am a surgical nurse and have used these 'bellows' devices..

As for the one shown here, it looks good - safe and affordable, but I hope they will use this under the care and advice of a physician. Suction is not always appropriate for all wound healing..

Horton, could you tell us which types of wounds this wouldn't benefit?

Generally, suction is of benefit in deep wounds, such as surgical incisions into the joint areas, such as knee surgery - or deep wound abcesses..

However suction has been increasing used for 'hard to heal' wounds in diabetics..

Here is a good summary:

It has been my experience that suction does not work well, with the exception of diabetic ulcer treatment, in most out-patient settings..

I hope that helps..
