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?

  • 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 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.


What’s 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;

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?

  • 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.

  • 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

  • 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
