Flexible Structure with Flow Control Mechanism for Ventilation Mattress
김준희(Jun Hee Kim),김권희(Kwon Hee Kim) Korean Society for Precision Engineering 2019 한국정밀공학회지 Vol.36 No.1
Bedridden patients develop pressure sores, as a result of poor blood circulation and excessive humidity. Conventional bedsore mattresses are designed to vary interface pressure zones, between the body and mattress for improved blood flow. Another approach is to control interface humidity, by forced air circulation. An ideal solution may be interface humidity control, in addition to pressure zone control. In this paper, a thin and flexible structure is suggested for forced air ventilation, that can be placed atop pressure zone controlled mattresses. With fabric covers, drying performances are evaluated for a range of air flow rates.
