THERAPEUTIC MATTRESS ASSEMBLY

摘要

A therapeutic mattress assembly 10 comprising a mattress 14 having a substrate assembly54 that includes a plurality of cylinders 58 positioned side by side over the length of the mattress. Each cylinder 58 is configured as a low air loss system to allow air to flow into the cylinder from a source 20 and out of the cylinder through small holes 66 located on the top of each cylinder. An overlay assembly 118 provides a foam cushion 130 that provides a supporting surface above the substrate assembly 54 for the patient. A calf lift bladder 146 operates to effectively raise or lower the patient's feet to prevent pressure related injuries. A lateral rotation assembly 18 selectively raises and lowers a selected half of the mattress 14 to turn patients in a lateral direction. A bolster 134, 138 inflates in response to the lateral rotation assembly 18 to secure the patient within the mattress 14.
