    Abstract: A disposable endotracheal airway adapter for use in proximity of a patient's mouth in the measurement of the concentraton of respiratory gases. The disposable airway adapter of the invention provides a conduit for patient respiratory gases and allows the passage of infrared radiation through the gases for measuring the constituent concentration of the respiratory gases while keeping the patient gases from coming in contact with the analyzer mechanism. The body of the airway adapter is designed to connect in series with the airway tubing which connects a patient to a mechanical respirator or anesthesia breathing circuit. The body of the airway adapter is very light in weight and is formed of inexpensive material such as polyethylene or polypropylene so that it may be manufactured inexpensively and discarded after each use. An inexpensive optical window in the adapter is also formed of material such as polyethylene or polypropylene so that the gas analyzer can pass light into the sample for analysis. Preferably, the optical windows of the invention are made of the same material as the adapter body. Since the adapter of the invention may be disposed of after use on a single patient, sterilization expenses and cross-contamination may be minimized. Also, calibrating integrity is maintained through a calibration process which accounts for the non-linearity of the absorption spectra of the window material in the region of interest.

    Abstract translation: 用于测量呼吸气体浓度的患者口腔附近的一次性气管插管气道适配器。 本发明的一次性气道适配器提供用于患者呼吸气体的导管，并允许红外辐射通过气体，用于测量呼吸气体的组成浓度，同时保持患者气体不与分析器机构接触。 气道适配器的主体设计成与将患者连接到机械呼吸器或麻醉呼吸回路的气道管串联连接。 气道适配器的主体重量非常轻，并且由诸如聚乙烯或聚丙烯的廉价材料形成，使得可以在每次使用后廉价地制造和丢弃。 适配器中的廉价的光学窗口也由诸如聚乙烯或聚丙烯的材料形成，使得气体分析仪可以将光通过样品进行分析。 优选地，本发明的光学窗口由与适配器主体相同的材料制成。 由于本发明的适配器可以在使用后在单个患者身上处理，因此可以使灭菌费用和交叉污染最小化。 此外，校准完整性通过考虑到感兴趣区域中窗口材料的吸收光谱的非线性的校准过程来维持。

    Abstract: A water separator adapted for use in a gas monitor includes a gas inlet port, a gas outlet port, a two-stage gas/water separator section, and a fluid reservoir. The two-stage gas/water separator section includes a first portion defining a first chamber which communicates with the gas inlet and gas outlet ports via a connecting conduit, a second portion defining a second chamber which communicates with the first chamber and the fluid reservoir, and an intermediate portion interposed between the first and second portions and defining a constricted passage between the first and second chambers. The second chamber has a frusto-conical shape in longitudinal cross section.

    Abstract: The percentage gas concentration within a sample as measured in a conventional optical bench is derived from the composite signal of the reference beam and sample beam transmitted through a sample cell in the optical bench. The primary source, which generates the reference beam and the secondary source which generates the sample beam are driven ninety degrees out of phase. The composite signal derived from the detector in the optical bench is digitized and then integrated according to the quadrature of the primary component of the composite signal derived from the reference beam, and is also integrated according to the quadrature of the secondary component of the composite signal derived from the sample beam. What is obtained is the integral of the absolute value of the secondary component and the integral of the absolute value of the primary component of the composite signal over one cycle of the reference beam and sample beam. The ratio of these component signals is computed to obtain a signal which is related to the percentage concentration of reference gas contained within the sample.
