Fuzzy logic control for negative pressure wound therapy

Abstract

Negative Pressure Wound Therapy (NWPT) has been successful treated the acute and chronic wound by promoting the wound healing. Many medical techniques like NPWT are available in this world but not approachable for many patients due to high in cost and lack of devices. In order for most of the patients accessible to NPWT, an inexpensive NPWT system is explored in this study. Aim of this work is to design a fuzzy logic conntrol of NPWT system that can generate negative pressure and the negative pressure can be regulated within the range. A NPWT system consists of vacuum pump, drainage tubes, wound dressing, fluid collecting canister and adhesive film dressing. Therefore, in this thesis, a miniature vacuum pump, canister and Arduino micro-controller were used in order to build up a functional NPWT system. The system has been designed to supply negative pressure from 0 mmHg to 200mmHg and negative pressure can be controlled. The fuzzy logic control system performance is compared and proven that it has better performance compared to boolean logic control. In conclusion that this system is able to function according to the require specification and suitable for home healthcare wound healing device with safety precaution implement and system stabilization is improved in future.
