    • The present invention is directed to a gas sampling system for conducting respiratory gases from a patient respiratory gas output mechanism to a respiratory gas monitoring device. The respiratory gas monitoring device is equipped with a monitor input connector. The gas sampling system includes an input connector configured to couple the gas sampling system to the patient respiratory gas output mechanism. A gas sampling tube is coupled to the input connector. The gas sampling tube is configured to conduct the respiratory gases from the patient to the gas monitoring device. An output connector couples the gas sampling tube to the monitor input connector. An output dryer tube is coupled between the gas sampling tube and the output connector. The output dryer tube is characterized by a tube length and a relative moisture removal efficiency. The relative moisture removal efficiency is dependent on the tube length. The tube length is selected to limit the moisture content of the respiratory gasses being directed into the respiratory gas monitor to a predetermined level.
    • 本发明涉及一种用于将呼吸气体从患者呼吸气体输出机构传导到呼吸气体监测装置的气体采样系统。 呼吸气体监测装置配有监视器输入连接器。 气体采样系统包括被配置为将气体采样系统耦合到患者呼吸气体输出机构的输入连接器。 气体采样管耦合到输入连接器。 气体采样管构造成将呼吸气体从患者传导到气体监测装置。 输出连接器将气体采样管连接到监视器输入连接器。 输出干燥管耦合在气体采样管和输出连接器之间。 输出干燥管的特征在于管长度和相对湿度去除效率。 相对去湿效率取决于管长度。 选择管长度以将被引导到呼吸气体监测器中的呼吸气体的水分含量限制到预定水平。
