A Novel Approach to Treating Pressure Ulcers LTU Biomedical– Robert Karas & Corina Malone UDM Mechanical Engineers– Frank McClosky, Jacob Dodman, & Bobby Lorenz UDM Nurses – Lydia Jacob, Christina Osterhout, & Victoria Murad

Background of Pressure Ulcers The 4 stages of pressure ulcers are caused due to unrelieved pressure, increased temperature and friction Pressure ulcers are developed in 2.5 million people in the U.S. annually According to the National Pressure Ulcer Advisory Panel (NPUAP) to prevent pressure ulcers it is important to reduce friction, reduce moisture, and redistribute pressure

Market Analysis 25% of Spinal Cord Injury patients 65,000 Wheelchair bound individuals $43,180 average cost of a stage 1-3 pressure ulcer treatment $2.8 billion dollar market available in pressure ulcer prevention

Stakeholder Analysis Hospitals Nursing Homes Patients Medical equipment companies Caregivers Home healthcare agencies Insurance Companies

CUSTOMER INTERACTION Based on customer interactions: We have determined that patients would prefer to have a device that maximizes independence but provides environment that reduces risk of forming pressure ulcers. 90% of the patients suffered from Stage I-III None of the patients were currently using other devices to manage or prevent pressure ulcers. 30% of the patients used other devices which failed to prevent and/or effectively manage pressure ulcer formation Based on clinician interactions: There is a need for a device that effectively reduces the risk of pressure ulcer formation and provides a low cost. Pressure Ulcers cant be healed but can be prevented by maintaining skin integrity

NEEDS STATEMENT There is a need to provide a cost effective device which is more effective at lowering risk factors of pressure ulcer formation in patients confined to a wheelchair for an extended period of time.
