Introduction
Introduction

  • The ‘Negative Pressure Therapy’ (NPT) system introduced in early 90’s,

  • Gained massive popularity due to it’s effectiveness.

  • Based - controlled subatmospheric pressure.


How it s works
How It’s 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 it s works1
How It’s 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.



How the system works
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 works1
How The System Works?

  • With an intervening (2) reservoir to collect the effluent from the wound.

  • “Canister”


How the system works2
How The System Works?

  • These is the connected by semi-rigid tubing to a (3) machine, which generate and regulate negative pressure;

Main objective
MainObjective

  • To develop a cheap, versatile, user friendly and effective wound management system based on the principle of negative pressure treatment utilising centralised hospital suction system.

  • Otherobjectives:

    • 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
Why Do We Need This Device?

  • Currently available system is too expensive.

  • Modified system

    • Lack of pressure regulator

    • Intermittent therapy is not possible

    • No alarm/warning system


Features of negative pressure regulator required
Features of Negative Pressure Regulator Required.

  • Cheap, Small/light

  • Silent operation

  • Plug into the wall type (into the available wall suction socket)

  • Has automated pressure regulator (mechanical/electronic) with digital/analogue pressure indicator

  • Has 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 project
The benefit of this project

  • To 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 marketing

  • Can be used safely for Negative Pressure Wound Therapy
