Abstract


Negative pressure wound therapy (NPWT) is a technique that enhances the healing process by applying negative pressure on the chronic or acute wounds. It has been diffusely adopted for treatment of trauma wound, chronic wound, or deep sternal wound infections due to its excellent healing result. However, there were several injuries and death cases caused by the unstable pressure generated from the wound treatment. This paper aims to design a stable negative pressure regulator by using fuzzy logic controller (FLC) .The proposed control approach is able to regulate the negative pressure within the desired range for healing process. The NPWT system consists of adhesive film dressing, wound dressing, fluid collecting canister, drainage tubes, vacuum pump, and microcontroller. The NPWT system developed is able to supply negative pressure from 0mmHg to 200mmHg and the negative pressure supply can be controlled. The effectiveness of FLC pressure controlling and Boolean logic controller method is validated by experiments. In conclusion, it is proven that the proposed method is able to provide a safe wound treatment in future.
