    • An apparatus for conditioning gas for use in a medical procedure, such as endoscopy, the gas being received into the apparatus from a gas source. The apparatus comprises a housing defining a chamber having an entry port and an exit port. A humidification means comprising at least one water-retainer layer is disposed within the chamber in the path of travel of the gas for humidifying the gas as it passes through the chamber. A humidity sensor is disposed within the chamber that senses the humidity of the gas exiting the chamber. A monitoring circuit is connected to the humidity sensor that detects when the chamber requires a recharge of liquid based on the humidity of the gas in the chamber, and generates a recharge signal indicative thereof. A charging port on the housing provides access into the chamber to recharge the chamber with water. A heating element and temperature sensor are also disposed within the chamber. A control circuit further regulates the temperature of the gas exiting the chamber.
    • 一种用于调节用于医疗过程(例如内窥镜检查)的气体的装置,气体从气体源被接收到设备中。 该装置包括限定具有入口和出口的腔室的壳体。 包括至少一个水保持层的加湿装置设置在气体的行进路径内的腔室内,用于在气体通过腔室时加湿。 在室内设置湿度传感器,其感测离开室的气体的湿度。 监测电路连接到湿度传感器,该湿度传感器基于腔室中气体的湿度来检测室何时需要对液体进行再充电,并产生指示其的再充电信号。 外壳上的充气口可进入腔室,以便用水给腔室充电。 加热元件和温度传感器也设置在腔室内。 控制电路进一步调节离开室的气体的温度。
