Embodiment Construction

[0017] figure 1 Schematically exemplified is a pressure support system 10 configured to provide pressure support therapy to a subject (not shown). Pressure support system 10 is configured to provide pressure support therapy in the form of a flow of gas delivered to the airway of a subject. Pressure support therapy may be dynamic, wherein one or more parameters of gas flow produced by pressure support system 10 can be adjusted based on detection of one or more parameters. For example, the pressure of the gas flow may increase according to a change in one or more parameters indicative of a respiratory event (eg, apnea, snoring, etc.). In one embodiment, pressure support system 10 includes one or more of pressure generator 14, electronic storage 16, user interface 18, sensor 20, processor 22, humidifier 24, and / or other components.

[0018] In one embodiment, pressure generator 14 is configured to generate a flow of gas for delivery to the airway of a subject. Pressure generat...

Abstract

A pressure support system configured to provide pressure support therapy includes a humidifier that holds an enhanced amount of liquid while enhancing the power consumption of the pressure support system and enabling relatively rapid adjustments to humidity level. The humidifier includes a humidification chamber and a holding chamber, and a partition that divides the holding chamber from the humidification chamber such that liquid from the holding chamber replenishes liquid held in the humidification chamber. The partition, however, also provides a level of thermal isolation for the humidification chamber from the holding chamber.

Description

[0001] This patent application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61 / 290,349, filed December 28, 2009, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a pressure support system configured to provide pressure support therapy to a subject, wherein the pressure support system includes a humidifier configured to adjust the humidity of the gas provided by the pressure support system to the subject Take control. Background technique [0003] Pressure support systems that provide pressure support therapy to the airway of a subject are well known. Some conventional pressure support systems include a humidifier configured to control the level of humidity of the gas provided to the subject during pressure support therapy. In conventional pressure support systems, increasing the volume to accommodate liquid for the humidifier increases the convenience of the pressure support ...
