2019-955 Multi-Stable Compliant-Mechanism for Bed Sore Prevention

SUMMARY

UCLA researchers in the Department of Mechanical and Aerospace Engineering have designed a low-cost, lightweight and easily adjustable mattress that prevents bed sores.

BACKGROUND

Every year in the US, 2.5 million patients are affected by bed sores. 60,000 patients die every year as a direct result of the condition, resulting in $9.1 - $11.6 billion in treatment costs every year.  Currently, the most effective bed sore prevention approach is to use silica-bead air fluidized beds. These beds, however, are expensive, extremely heavy and difficult to adjust. There is a need for a simple, cost effective and lightweight solution to prevent bed sore formation.

INNOVATION

Professor Hopkins and his research team at UCLA have designed a low-cost mattress that can prevent bed sores with high efficacy. The mattress would be lightweight and easily reconfigured. The mattress design has a unique deformation mechanism that adjusts the mattress pressure points.  The energy required to operate the mechanism is minimal. The design generates very little noise and wear, making it an ideal solution for preventing bed sore formation.
