Abstract
A float retention arrangement and related methods for a humidification chamber that includes at least one float that operates an inlet valve that controls a flow of water through a water inlet opening of the humidification chamber. A cover of the humidification chamber defines an interior space, at least one gas port and a float retention opening. A component forms at least a portion of a water supply conduit for supplying water from a water source to the water inlet opening. The component is insertable into the float retention opening and is positionable to contact and retain the at least one float in a non-use position. In some configurations, the component can be a water spike.
Claims12
A humidification chamber, comprising;
- a cover defining an interior space, the cover comprising at least one gas port, a water inlet opening and a float retention opening;
- at least one float configured to operate an inlet valve that controls a flow of water through the water inlet opening in use;
- a water supply conduit having a first end and a second end, the first end being connected to the water inlet opening;
- an adapter connected to the second end of the water supply conduit and configured, in use, to couple the water supply conduit to a source of water;
- wherein the adapter is insertable into the float retention opening and is positionable to contact and retain the at least one float in a non-use position.
A humidification chamber, comprising:
- a cover defining an interior space, the cover comprising at least one gas port, a water inlet opening and a float retention opening;
- at least one float configured to operate an inlet valve that controls a flow of water through the water inlet opening in use;
- a component that forms at least a portion of a water supply conduit for supplying water from a water source to the water inlet opening;
- wherein the component is insertable into the float retention opening and is positionable to contact and retain the at least one float in a non-use position.
A method of retaining a float of a humidification chamber, comprising:
- inserting an adapter that is connected to a free end of a water supply conduit through a float retention opening in a cover of the humidification chamber until the adapter moves and retains the float in a non-use position, wherein an end of the water supply conduit opposite the free end is coupled to a water inlet of the humidification chamber.
A method of using a humidification chamber, comprising:
- removing an adapter that is connected to a free end of a water supply conduit from a float retention opening in a cover of the humidification chamber to release a float from a non-use position, wherein an end of the water supply conduit opposite the free end is coupled to a water inlet of the humidification chamber.
