INDIAN INSTITUTE OF TECHNOLOGY MADRAS DEPARTMENT OF ENGINEERING DESIGN Robotics Laboratory DESIGN OF ROBOTIC SYSTEM FOR ACUTE WOUND CLEANING GOAL PURPOSE To design an automated system to clean acute wounds in hospital settings Wound cleaning is a repetitive, time consuming and tedious process, which is often neglected. Proper cleaning ensures removal of dirt, devitalized tissues and bacteria from the wound. It also curtails further contamination and spread of infections over the wound. WOUND CLEANING The process involves exposing the wound to a pressurized fluid, commonly saline water or tap water., either continuously or in a pulsated jet form until all the contaminants are removed. VISION SYSTEM •Image Capture •Image Processing •Location •Area •Severity WOUND CHALLENGES 1. Design of manipulator 2. Wound irrigation system design 3. Wound detection 4. Manipulator control 5. Waste collection system CONTROLLER •Arm Motion Control •Irrigation Control MANIPULATOR SUMMARY The idea is to automate the process of wound cleaning using a low cost robotic arm. In this system, the wound is detected by a vision system, which captures images of the wound. These are processed to obtain quantifiable information of the wound such as its location, area and the severity. The controller then actuates the arm and the wound irrigation system to clean the wound. Researchers: Dr. Asokan T, K Murali Krishna
