Vacuum Regulator Adapter Device For Wound Management System.Principle Researcher : Prof Ahmad Sukari Halim Co-Researcher: Dr Arman Zaharil Mat Saad Other Team: School of Engineering Mechanical & Electronic

IntroductionThe Negative Pressure Therapy (NPT) system introduced in early 90s,Gained massive popularity due to its effectiveness.Based - controlled subatmospheric pressure.

How Its works?The concept was based on the mechanics of physics Causes mechanical stress to tissues Mitosis is stimulated, New vessels are formed, and Expedite wound healing

How Its works?Assists in wound healing by:provides a moist/protected environments reduces peripheral oedema around the wound stimulates circulation to the wound bed decreases bacterial colonization increases the rate of granulation tissue formation and epithelialization.

Whats required for NPT system?

How The System Works?Basically the system has 3 main components. (1)The semi-occlusive dressing materials that consist of polyurethane foam and see through semi-permeable plastic adhesive/drapes.

How The System Works?With an intervening (2) reservoir to collect the effluent from the wound. Canister

How The System Works?These is the connected by semi-rigid tubing to a (3) machine, which generate and regulate negative pressure;

Main ObjectiveTo develop a cheap, versatile, user friendly and effective wound management system based on the principle of negative pressure treatment utilising centralised hospital suction system. Other objectives:To develop device with accurate vacuum pressure regulator for multipurpose usage.To incorporate electronic or mechanical components to the centralised hospital suction system for negative pressure regulator and cyclical vacuum therapy.

Why Do We Need This Device?Currently available system is too expensive.Modified system Lack of pressure regulator Intermittent therapy is not possibleNo alarm/warning system

Features of Negative Pressure Regulator Required.Cheap, Small/lightSilent operationPlug into the wall type (into the available wall suction socket)Has automated pressure regulator (mechanical/electronic) with digital/analogue pressure indicatorHas self timer for intermittent therapy (on and off mode eg. 10 minutes on and 2 minutes off therapy for 5 days)Alarm system to indicate required pressure not achieved/leaked/malfunction and alarm off mode/silent

The benefit of this projectTo produce a new easy to use and multipurpose wall suction pressure adaptor and regulator.New product invention by the university.The product will be highly value in hospital set up and has potential for world wide marketingCan be used safely for Negative Pressure Wound Therapy
