Abstract
An embodiment in accordance with the present invention provides a water dissipation device to remove water vapor from a humidified gas traveling through a breathing circuit between a patient and a ventilator, or a ventilator and a patient. The present invention includes a water dissipation device having a housing defining entry and exit ports for coupling to the breathing circuit and a breathable medium permeable to water vapor and impermeable to liquid water bacteria, viruses and other gases enclosed within said housing.
Claims20
A water dissipation device for a breathing circuit, comprising:
- a housing having
- a cylindrical bottom container having a side wall, said side wall defining a top opening,
- a lid mounted on said top opening, the housing defining an entry port and an exit port for coupling to a breathing circuit and defining a first flow path between said entry and exit ports;
- a breathable medium enclosed in said housing;
- and,
- the housing defining a second flow path from the entry port of the housing through the tubular breathable medium to exit the housing from at least one opening other than the exit port.
A water dissipation device for a breathing circuit, comprising:
- a cylindrical caged body enclosing an annular breathable medium;
- a first end portion defining an entry port coupled to a first side of said caged body;
- a second end portion defining an exit port coupled to a second side of said caged body;
- the cylindrical caged body defining a first flow path between the entry port and the exit port;
- and,
- the cylindrical caged body defining a second flow path from the entry port through the annular breathable medium and the cylindrical caged housing.
A water dissipation device for a breathing circuit, comprising:
- a housing having
- a cylindrical bottom container having a side wall defining a plurality of windows,
- a lid mounted on the cylindrical bottom container, the housing defining an entry port and an exit port for coupling to a breathing circuit and defining a first flow path between said entry and exit ports;
- a breathable medium enclosed in said housing;
- and,
- the housing defining a second flow path from the entry port of the housing through the tubular breathable medium to exit the housing from at least one of the plurality of windows.
