Abstract
A water dissipation device for a breathing circuit is provided, including a bucket-shaped hollow composite structure having walls made of a first inner layer made of water vapor wicking material, and a second outer layer of a water vapor breathable medium surrounding the first inner layer. The device defines a flow space surrounded by the composite structure to provide a superior way of removal of moisture or water vapor from a breathing circuit, due to the greater surface area of flow spaces bounded by a water vapor breathable medium and the use of a water vapor wicking material and relatively long dwell times and flow paths through the device. The result is that when the device is connected to a breathing circuit, rainout or condensation in the breathing tube and collection of water within the breathing circuit is significantly reduced.
