摘要	The present disclosure provides a detector for a capnography device for uninterrupted monitoring of respiratory gasses of a subject, the detector includes a gas flow chamber, configured to permit flow of respiratory gasses between a first orifice and a second orifice thereof, a bandstructure cascade laser configured to provide mid-infrared wavelength laser radiation to the flow chamber, the mid-infrared wavelength laser radiation having wavelengths that at least partially correspond to an absorption spectrum of carbon-dioxide molecules, and a first radiation sensor configured to obtain mid-infrared wavelength radiation passing through the chamber and to provide a radiation intensity signal indicative of changes in carbon-dioxide level in respiratory gasses within the chamber during at least one respiration cycle.
其他摘要	本公开提供了一种用于二氧化碳图检查装置的检测器，用于对对象的呼吸气体的不间断监测，所述检测器包括气流室，构造成允许呼吸气体在其第一孔口和第二孔口之间流动，构造级联激光器以向所述流动室提供中红外波长激光辐射，所述中红外波长激光辐射具有至少部分地对应于二氧化碳分子的吸收光谱的波长，以及第一辐射传感器，其被配置为获得中红外波长辐射穿过所述室并提供辐射强度信号，所述辐射强度信号指示在至少一个呼吸循环期间所述室内的呼吸气体中二氧化碳水平的变化。
