Decubitus ulcers are pressure sores basically generated by prolonged unchanging sitting posture in wheelchairs especially by paraplegic patients with insensitive skin or physical disabilities. Currently available methods for prevention are providing weight shifts using special pads and cushions, cleaning, drying and moisturizing skin, changing the wet pads and clothes etc. This project concentrates on measurement and analysis of concentration of weight and redistribution of the same to prevent the formation of decubitus ulcer. By convenient random sampling seven subjects ranging from 50 Kg to 80 Kg were studied upon, to identify the weight concentration while sitting on a wheel chair. Based on the results of study, the seat was divided into 3 areas. A pressure shifting mechanism is designed depending on the weight concentration on these plates and elapsed time. The shifting of pressure points in turn reduces the chances of shear thereby preventing the chances of decubitus ulcers. © 2017 Elsevier Ltd. All rights reserved.
