Problems solved by technology

Use of separate steam delivery units complicates use of high flow therapy systems as it requires healthcare professionals to shut down the system and switch steam delivery units
Switching of the steam delivery unit may also interrupt patient treatment

Embodiment Construction

[0042] Certain illustrative embodiments will be described in order to provide a thorough understanding of the systems, devices, and methods described herein. Although the embodiments and features described herein are specifically described for use in conjunction with high flow therapy systems, it should be understood that all components and other features outlined below may be combined with each other in any suitable manner and may be adapted and applied to other types of Respiratory therapy and respiratory therapy equipment, including mechanical ventilation, continuous positive airway pressure (CPAP), oxygen masks, venturi masks, low-flow oxygen therapy, tracheostomy masks, and more.

[0043] The systems, devices, and methods described herein control the relative humidity of breathing gas delivered from a breathing gas humidification system. The systems, devices, and methods use a single vapor delivery unit to prevent or prevent excessive humidification of breathing gas at lo...

Abstract

Systems, methods and apparatus are presented for humidifying breathing gas using a vapor delivery unit. The method includes: providing a first vapor delivery unit having a gas passage and a liquid passage; delivering liquid to the liquid passage; delivering gas to the gas passage; humidifying by delivering vapor from liquid in the liquid passage to gas in the gas passage gas; expelling the humidified gas out of the vapor delivery unit at a first relative humidity and a higher gas flow rate; and reducing the gas flow rate through the first vapor delivery unit to less than the lower gas flow rate while preventing the relative humidity from exceeding the first relative The amount of humidity is greater than the acceptable limit.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application No. 14 / 587,898, filed December 31, 2014, which is incorporated herein by reference in its entirety. Background technique [0003] Patients with respiratory disorders are often treated with respiratory assistance devices, which deliver supplemental breathing gases to the patient. Such devices can deliver gas to patients using high flow therapy (HFT). HFT devices deliver breathing gas to a patient at a high flow rate via an interface such as a nasal cannula, thereby increasing the patient's fraction of inspired oxygen (FiO2), reducing the patient's respiration effort, or both. This helps patients recover from respiratory conditions such as respiratory distress or bronchospasm. Some HFT devices heat and humidify the delivered breathing gas for medical reasons (eg, to maintain tissue flexibility in surfactant deficient patients, or to maintain mucosal integrity) ...
