The objective of the proposed project is to fabricate and test prototypes of a novel nasal interface for use in delivering home oxygen therapy. The interface includes air entrainment ports of adjustable open area, which allows for regulation of the pressure signal used by oxygen delivery devices to sense patient inspiration and trigger oxygen delivery. When used with a portable oxygen concentrator, the nasal interface will improve triggering efficiency, thereby providing a single source solution to a patient's daytime and nighttime oxygen needs. Costs and complexity of maintaining multiple oxygen delivery devices (stationary and portable sources) in the patient's home would be eliminated. In addition, a single 24-hour portable oxygen source would allow patients the convenience of travel including overnight stays away from home, without sacrificing oxygenation.The proposed reduction-to-practice project will provide key data demonstrating the improved oxygen delivery achieved using the nasal interface with commercial portable oxygen concentrators.

该项目的目标是制造和测试一种用于家庭氧疗的新型鼻腔接口的原型。该接口包括可调节开放面积的引气口，允许调节氧气输送设备所使用的压力信号，以感知患者的吸入并触发氧气输送。当与便携式氧气浓缩器一起使用时，鼻腔接口将提高触发效率，从而为患者的白天和夜间氧气需求提供单一来源的解决方案。在患者家中维护多个氧气输送设备(固定和便携式来源)的成本和复杂性将被消除。此外，单一的24小时便携式氧源将使患者在不牺牲氧气的情况下方便旅行，包括离家过夜。拟议的减少到实践项目将提供关键数据，证明使用商用便携式氧气浓缩器的鼻腔接口实现了更好的氧气输送。
