Abstract
A water dissipation device for removing water vapor or moisture from a breathing circuit is provided, including an upper lid portion, an entry port and an exit port. An outer cover structure extends from the upper lid portion to define an enclosed volume. An inner frame extends from the upper lid portion inside the outer cover structure. The outer cover structure includes a first layer of water or moisture wicking material and a second layer of water vapor breathable medium, and has an inner surface area bounding an inner flow space such that water vapor or moisture can permeate from the inner flow space through the outer cover structure out of device. The device can include an inner cup structure extending from the upper lid portion into the enclosed volume to displace the enclosed volume and define and bound a portion of the inner flow space and compressible volume therein.
