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.

1. A water dissipation device for a breathing circuit, comprising: an entry port and an exit port for coupling the device to the breathing circuit, the entry port to receive fluid flow from the breathing circuit, the device further defining an inner flow space fluidly coupled to the entry port and exit port,a cover structure partially bounding the inner flow space and including an inner layer made of wicking material, andan outer layer over the inner layer, the outer layer made of a water vapor breathable medium which permits the passage of water vapor and does not permit the passage of liquid water. 2. The water dissipation device of claim 1, further comprising: an upper lid structure defining said entry port and exit port, andwherein the cover structure is a bucket-shaped structure having a closed bottom end and an open top end coupled to said upper lid structure, the inner flow space being enclosed by the cover structure and upper lid structure. 3. The water dissipation device of claim 2, further comprising: an inner frame enclosed by the cover structure, the inner flow space being partially disposed between the inner frame and cover structure, the inner frame enclosing a majority of a volume enclosed by the cover structure. 4. The water dissipation device of claim 3, wherein the cover structure has a substantially cylindrical portion between its open top end and closed bottom end and the inner frame has a substantially cylindrical portion enclosed by the substantially cylindrical portion of the cover structure. 5. The water dissipation device of claim 4, wherein the inner frame defines a lower opening proximate the closed bottom end of the cover structure, the device further comprising a conduit connecting the lower opening with the exit port, the conduit being surrounded by the inner frame. 6. The water dissipation device of claim 3, wherein the inner frame includes a plurality of longitudinal ribs along an outside surface of its substantially cylindrical portion, the plurality of longitudinal ribs dividing a portion of the inner flow space into a plurality of flow channels between the inner frame and cover structure. 7. A water dissipation device for a breathing circuit, comprising: a cover partially enclosing a flow space, said cover having at least two layers, including a first inner layer made of wicking material, and a second layer outside of and surrounding the first inner layer, the second layer made of a water vapor breathable medium which permits the passage of water vapor and does not permit the passage of liquid water;an entry port for fluidly coupling the flow space to the breathing circuit, said flow space being at least partially bounded by the first inner layer,the entry port, flow space and cover providing a flow path for water vapor out of the breathing circuit. 8. The water dissipation device of claim 7, wherein the cover is bucket-shaped and defines a top opening coupled to an upper lid defining said entry port, the flow space being enclosed by the cover and upper lid and in fluid communication with the entry port. 9. The water dissipation device of claim 8, further comprising: an inner frame enclosing a majority of the volume enclosed by the cover, the inner frame being surrounded by the cover, the flow space being partially disposed in an annular volume defined between the inner frame and cover,wherein a lower end of the cover and the upper lid are disposed at respective lower and upper end portions of the device. 10. The water dissipation device of claim 9, wherein the annular volume includes an upper end in fluid communication with the entry port defined by the upper lid, and further comprising:an inner flow dispersal element disposed between the inner frame and upper lid and adjacent an upper end of the annular volume defining a plurality of openings for dispersing flow received through the entry port into the annular volume. 11. The water dissipation device of claim 9, wherein the inner frame defines a lower opening proximate the lower end of the cover, the lower opening being in fluid communication with the annular volume and an exit port defined by the upper lid. 12. The water dissipation device of claim 9, wherein the cover has a substantially cylindrical portion above its lower end and the inner frame has a substantially cylindrical portion enclosed by the substantially cylindrical portion of the cover. 13. A water dissipation device for a breathing circuit, comprising: a hollow bucket-shaped thin flexible membrane composite cover structure defining a top opening and closed bottom and having walls made of a first inner layer made of wicking material, and a second outer layer surrounding the first inner layer, the second outer layer made of a water vapor breathable medium which permits the passage of water vapor and does not permit the passage of liquid water;an upper lid covering said top opening and having an entry port for receiving flow from a breathing circuit;an inner frame structure disposed inside a volume enclosed by the cover structure between the upper lid and closed bottom of the cover structure;the cover structure enclosing a flow space for receiving flow from the entry port, said flow space being bounded by the upper lid, the first inner layer and the inner frame, the flow space being in fluid communication with the entry port and providing a flow path for water vapor flowing into the device from said entry port to exit the device from said volume through said cover structure. 14. The water dissipation device of claim 13, wherein the upper lid defines an exit port. 15. The water dissipation device of claim 13, wherein the cover structure has a substantially cylindrical portion above its closed bottom and the inner frame structure has a substantially cylindrical annular portion enclosed by the substantially cylindrical portion of the cover structure.
