Portable, wireless and easy to use device for Negative Pressure Wound Therapy

Abstract

Wound healing is a natural biological process in the human body, achieved through four interdependent, precisely and highly programmed phases. Every wound is unique and is affected by various factors hence optimization of wound healing mechanism based on the complexity of wound is of utmost importance. NPWT has emerged to be a prominent systematic wound treatment practice for chronic wounds such as arterial ulcers, diabetic foot ulcers, non healing surgical wounds, pressure ulcers, traumatic wounds, vasculitic ulcers (leg), venous stasis ulcers, etc. Typically, an optimum pressure range of 88 to 125 mmHg exhibits positive and promising effects in this kind of therapy. Despite assisting the wound healing mechanism in many ways, this method poses certain problems too. The key to this process lies in optimization of the value of negative pressure, duration of negative pressure application, and the number of times the treatment has to be performed based on the type of wound. Here in this study our aim is the modification of negative-pressure wound therapy such that we make this device portable, wireless and easy to operate on different negative pressure settings. Other than these optimizations we have incorporated the process of instillation wherein wound flushing is done with help of saline, antiseptic, anti-infective drugs or growth factor solutions.
