摘要： A humidifier includes a base configured to retain a body of liquid therein, a top cover, and a seal disposed between the top cover and the base. At least a portion of the base is constructed of a heat conducting material. The top cover defines both an inlet and an outlet communicated with an interior of the base. The inlet is configured to receive pressurized breathable gas and the outlet is configured to deliver the pressurized breathable gas with added humidity.

摘要： A humidifier tub includes a first side having an air inlet opening configured to receive the pressurized flow of respiratory gas. A second side opposes the first side. An air outlet opening is configured to discharge the pressurized flow of respiratory gas with added humidity. An inlet passage extends from the air inlet opening toward the second side so that the pressurized flow of respiratory gas travels through the inlet passage in a first direction. A guidance structure is located between the first and second sides and positioned so that a traveling direction of the pressurized flow of respiratory gas changes from the first direction to a second direction upon the pressurized flow of respiratory gas engaging the guidance structure. The guidance structure extends downward from a lid. In addition, the first direction is a lateral direction and the second direction is a downward direction.

摘要： A humidifier includes a humidifier tub including an air inlet and an air outlet. The air outlet may have an exit port positioned in a plane disposed below the air inlet. A base plate is provided to the bottom of the humidifier tub. The base plate and humidifier tub define a water chamber adapted to receive a volume of water. The humidifier tub may include a guidance structure adapted to direct air entering the humidifier tub via the air inlet to swirl downwardly and around within the humidifier tub reaching the water surface before exiting the exit port. The tub may include a structure to prevent the inadvertent entry of water from the tub to the flow generator.

摘要： A vent system for use during respiratory therapy with a flow of pressurized gas may provide a continuous vent flow of gas. The vent system may include a vent housing having an outer wall; an inner wall, the inner wall defining an inlet for the flow of gas; and a base positioned between the outer wall and the inner wall, the base having at least one first orifice and at least one second orifice. The vent system may include a membrane, the membrane being shaped and dimensioned such that the membrane does not cover the at least one first orifice to allow the vent flow through the at least one first orifice, and the membrane being shaped and dimensioned such that in a first position the membrane is positioned over the at least one second orifice to allow the vent flow through the at least one second orifice.

摘要： A flow generator is configured to pressurize a flow of breathable gas to within a range of about 2-30 cm H2O for delivery to a patient's airways. The flow generator includes a blower with at least one impeller and a motor configured to drive the at least one impeller. The flow generator also includes a substantially planar blower mount configured to support the blower. The blower mount includes a flexible blower receptacle portion configured to receive and support the blower. The blower receptacle portion includes an outlet opening that is axially aligned with an air outlet of the blower. The flow generator also includes housing that encloses the blower and the blower mount. The housing has an inner surface that engages a perimeter of the blower mount.

摘要： A humidifier is configured to humidify a flow of pressurized respiratory gas. The humidifier includes a tub base configured to retain a body of water and a tub lid configured to cover the tub base. The humidifier also includes an inlet passage configured to receive the flow of pressurized respiratory gas and deliver the pressurized respiratory gas to an interior of the humidifier. At least a portion of the inlet passage is configured to float on the body of water retained in the tub base.
