摘要 | A rugged, miniature, spectroscopic gas analyzer apparatus for rapid, non-invasive, multi-component breath monitoring and analysis and subsequent determination of Q or other medical diagnostic applications. The system is comprised of one or more IR emitters focussed by optical elements through a low volume sample cell receiving a sample input of a patient's breath for analysis. The patient either at rest or during exercise, inhales C2H2-SF6 mixtures (balance of oxygen and nitrogen) which is subsequently monitored upon exhalation for CO2, H2O, C2H2, and SF6 which can be employed to determine Q directly and accurately. Measurements are performed in real-time or via post-processing of stored original data. Due to its small size, ruggedness, and low power consumption, the monitor can conveniently be employed in the field or data can also be retrieved remotely using telemetry. The miniature analyzer operates on the principle of infrared absorption spectroscopy and allows very precise concentration measurements of the analytes of interest, without any bias or interference from other matrix components. |
其他摘要 | 一种坚固的微型光谱气体分析仪设备,用于快速,无创,多组分呼吸监测和分析,以及随后确定Q或其他医疗诊断应用。该系统包括一个或多个IR发射器,其由光学元件通过低容量样品池聚焦,接收患者呼吸的样品输入用于分析。患者在休息或运动期间吸入C2H2-SF6混合物(氧气和氮气的平衡),随后在呼气时监测CO2,H2O,C2H2和SF6,其可用于直接且准确地确定Q.测量是实时进行的,或者是通过对存储的原始数据进行后处理来进行的。由于其体积小,坚固耐用,功耗低,可以方便地在现场使用,也可以使用遥测技术远程检索数据。微型分析仪基于红外吸收光谱原理工作,可以对目标分析物进行非常精确的浓度测量,而不会受到其他基质组分的任何偏差或干扰。 |
