Embodiment Construction

[0016] FIG. 1 depicts a patient treatment system 10 that delivers a gas flow 12 of selectably controlled gas concentration levels to a patient 14 in accordance with one embodiment of the present invention. Patient treatment system 10 includes an air delivery system 16 that generates a pressurized flow of breathable gas 18 , also referred to as a primary flow. The gas delivery system 16 may include a non-invasive pressure support ventilator (non-invasive pressure support ventilator, NPPV) or a pressure support system, such as continuous positive airway pressure (Continuous Positive Airway Pressure, CPAP), Bi-level positive airway pressure (bi-PAP), automatic titration, proportional assist ventilation (PAV), C-Flex, Bi-Flex, PPAP or another conventional invasive or Non-invasive breathing mode.

[0017] Patient treatment system 10 includes modular oxygen regulator assembly 20, which serves as a standard stand-alone device capable of regulating a secondary gas flow, such as oxyge...

Abstract

A gas delivery system (10) that generates a pressurized flow of breathable gas for delivery to a patient. The system includes a primary gas delivery system (16, 16') for delivering a flow of pressured gas to the airway of a patient and supplemental gas delivery system (20, 20'). The supplemental gas delivery system is in the form of a modular gas regulator assembly that regulates the flow of supplemental gas from a gas source to the primary gas delivery system so that supplemental gas is delivered to the patient concomitant with the pressurized flow of breathable gas. The system allows the user to selectively control the gas concentration level of the supplemental gas, such as oxygen, helium, nitrogen or any combination thereof, and the pressurized flow of breathable gas delivered to the patient concomitantly.

Description

[0001] priority [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 60 / 697,744, filed July 8, 2005, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to respiratory therapy devices, and more particularly to systems comprising modular assemblies that allow the introduction of an auxiliary gas, such as oxygen, helium, nitrogen, or combinations thereof, while the primary gas flow is delivered to the patient. Background technique [0004] Ventilators, pressure support systems, and the like (collectively "ventilators") are commonly used to deliver a pressurized flow of breathable gas to a patient to treat a variety of medical conditions, including sleep-disordered breathing, among others. Some conventional ventilators are capable of controlling the oxygen concentration level of the gas delivered to the patient by combining supplemental oxygen and a pres...
