Abstract :The main objective of this project is to design a Negative Pressure Wound Therapy (NPWT) with an optimum cost. The existing model of Negative Pressure Wound Therapy has a problem that it is economically cost effective and the life span of the device is not more than 7 days. The reverse engineering is made on the current NPWT and the various parts are analysed. The Pressure regulation is analysed and evaluated. The material chosen for dressing has been analysed. The Bulb Vacuum System has been analysed and the possibility of combining with NPWT has been take into account. The parameters which have to be considered in developing the low cost Negative pressure wound therapy have been analysed.
