摘要： A tub is configured to contain a supply of water and be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain a supply of water and a tub lid connected to the tub base. The tub lid includes an inlet configured to receive a flow of breathable gas to be humidified and an outlet for the humidified flow of breathable gas. The tub further includes a water level indicator configured to indicate a level of the supply of water in the tub base. The water level indicator includes an inclined portion configured to direct the flow of breathable gas from the inlet away from the outlet. The water level indicator may be visible through the inlet.

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 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.

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 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 fluid connector system includes a first end portion with a first opening, a seal portion extending around a periphery of the first opening, and a latching portion. The seal portion is fixedly mounted to the first end portion. The fluid connector system also includes a second end portion that has an inner tube with a second opening, a sealing surface that extends around a periphery of the second opening, and an outer tube. The sealing surface may engage the seal portion to form a face seal to breathing gas travelling along the direction of engagement between the first and second end portions. The outer tube includes a complementary latching portion that may engage with the latching portion and may be depressed into a cavity formed between the inner and outer tubes. The seal portion is axially recessed relative to the latching portion along the direction of engagement.

摘要： Methods of an apparatus determine a quantity of a body of water in a humidifier such as by indirect measurement. The quantity of water may be determined by measuring one or more properties or characteristics, from which the quantity of water may be inferred. Characteristics of a flow of air, the humidifier, and/or the body of water may be measured. The characteristics may be, for example, pressure, flow rate, noise, vibration, temperature, electrical or mechanical. These may be measured by one or more sensors, which may be located in the humidifier, RPT device, air circuit or the patient interface. The methods described may have advantages, for example in being able to detect the quantity of water without requiring sensors to be present in a disposable component, and in some cases, without introduction of additional sensors.
