  1. 1. UAIPD 13-0042 Wheel Chair Cushion Monitor Inventor: Edward Sazonov
  2. 2. Current Problems • Approximately 25% of acute spinal cord injury (SCI) patients develop a pressure ulcer • Up to 80% of patients, overall, developing one at some point during their life • Pressure ulcers most commonly develop over bony prominences – Sacrum, ischium, heels, and trochanters as the most common locations • Prevention is the optimal treatment for pressure ulcers in SCI patients – Seated patients must be repositioned every 20 to 30 minutes to avoid prolonged pressure exposure – Pressure mapping is currently used to track weight shifting – Methods for pressure mapping are very expensive and not very accurate
  3. 3. • Novel cushion monitoring system – Detects prolonged pressure areas – Automatically mechanically adjusts patients to prevent pressure ulcers – Displays real time feedback to devices such as smartphones or tablets Technology
  4. 4. • Automatic detection and adjusting of patients • Real time feedback through user-friendly devices • Measures patients body weight and physical activity – Does not require removing patient from chair • Works with both manual and powered chairs Advantages
  5. 5. • Dr. Edward Sazonov – Associate Professor – Electrical and Computer Engineering – 30+ publications – 2 patent applications Inventor esazonov@eng.ua.edu
