ABSTRACT:
A hermetically sealed unitary liquid container of a thermoplastic material suitable for use in inhalation therapy is disclosed. The humidifier container comprises a body portion defined by an upstanding walled chamber having a bottom, a gas inlet duct unitary with the container body portion and defining a sealed gas inlet, and a sealed humidified gas outlet duct, both unitary with the container body portion. The container body portion constitutes a liquid reservoir and contains a predetermined amount of an aqueous aseptic or sterile aqueous liquid for humidifying a breathable gas. The gas inlet duct extends alongside the walled chamber, and has upper and lower end portions which are respectively situated above the container body portion and below usable liquid level in the container. The gas outlet duct communicates with the walled chamber above the usable liquid level. The gas inlet duct communicates with a gas diffuser defined by the container wall above the container bottom. The gas diffuser causes gas bubbles entering the liquid to rise through the liquid away from the container wall. The sealed gas inlet and the sealed gas outlet are provided with removable closures that can be broken off or twisted off.
