Nasal Interface Design for Use with Portable Devices Administering Long-Term Oxygen Therapy

该项目的目的是制造和测试一种新型鼻接口的原型，用于提供家庭氧气治疗。 该接口包括具有可调节开口面积的空气夹带端口，其允许调节氧气输送装置用于感测患者吸气和触发氧气输送的压力信号。 当与便携式氧气浓缩器一起使用时，鼻接口将提高触发效率，从而为患者的日间和夜间氧气需求提供单一来源的解决方案。 将消除在患者家中维护多个氧气输送装置（固定和便携式源）的成本和复杂性。 此外，一个单一的24小时便携式氧气源将使患者的旅行方便，包括过夜离家出走，而不牺牲oxygenation.The拟议的减少实践项目将提供关键数据，证明改善氧气输送实现使用鼻接口与商业便携式制氧机。

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.
