Negative-pressure wound therapy (NPWT) is known for improving a wide range of acute and chronic wounds. This technique has historic origins that go back to ancient times. Several theories were hypothesized around that technique of wound care including faster draining of the wound discharge, decreasing bacterial load of the wound, mechanical traction of wound edges by negative pressure and induction of wound surface hypoxia that encourages local angiogenesis. Using more economic machine, that was assembled by the author, and cheaper supplies on three different cases to test the efficacy of our method for wound care andhealing will be presented.
