Problems solved by technology

However, such a system is only suitable for LTOT systems, and there is no documented evidence that it improves the overall oxygen consumption of the system
Clearly, systems providing HFNT systems for home use are an unmet need; the high oxygen demand of the system cannot be easily met due to limited home oxygen supply

Embodiment Construction

[0020] As used herein, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. As used herein, the statement that two or more components or components are "coupled" shall mean that those components are directly or indirectly (ie, via one or more intervening components or components, whenever a link exists) connected or operative in Together. As used herein, "directly coupled" means that two elements are in direct contact with each other. As used herein, "fixedly coupled" or "fixed" means that components are coupled to move as a whole while maintaining a constant orientation relative to each other.

[0021] As used herein, the term "unitary" means that an assembly is created as a single piece or unit. That is, an assembly that includes separately created parts and then coupled together as a unit is not a "unitary" assembly or body. As used herein, the statement that two or more components or components are "engaged" wi...

Abstract

The system comprises an oxygen supply device; one or more sensors configured to generate an output signal conveying information about whether the patient is in an inspiration phase or an expiration phase; one or more valves; and a computer system. The one or more valves have: a) a first configuration in which the one or more valves operate to recover an excess flow of oxygen-enriched breathing gas during an inspiration phase; and b) a second configuration in which the one or more valves discharge the patient's expiratory flow to the atmosphere during the expiratory phase. The one or more physical processors are programmed with computer program instructions that, when executed, cause the computer system to provide input to the one or more valves based on the output signal, the provided input causing the one or more valves to move between the first and second configurations.

Description

technical field [0001] The present patent application discloses systems and methods for providing oxygen therapy to a patient. Specifically, the systems and methods of the present patent application are configured for oxygen recovery during high flow nasal therapy on a patient. Background technique [0002] High-flow nasal therapy (HFNT) systems are gaining a lot of traction in hospital care settings. Increasingly, it is used in place of or before an upgrade to a non-invasive ventilation (NIV) system. It is also considered an alternative to conventional (low-flow) long-term oxygen therapy (LTOT) systems for the treatment of non-hypercapnic hypoxic respiratory failure. Compared to LTOT systems, HFNT systems offer a range of physiological and clinical benefits: 1) improved patient comfort due to the use of nasal plugs instead of face masks; 2) due to high flow rates exceeding patient needs and resulting in less room air entrainment, it Achieved more reliable oxygen delivery...
