A system for disposing of expiratory air containing volatile anaesthetic gases during anaesthesia is described. It consists of a reservoir bag and an adjustable suction connected to the outlet port of the anaesthesia machine or the nonbreathing valvel. A valve is incorporated which opens to the atmosphere if the reservoir bag should collaps completely, thus creating a slight vacumn in the system. Another valve, opens if the bag should become fully expanded and a slifht positive pressure develop in the system. Halothane concentrations in the "anaesthetists breathing zone" were negligible when this system was being used.
描述了一种在麻醉期间处理含有挥发性麻醉气体的呼气的系统。它由一个储气囊和一个连接到麻醉机出口端口或非呼吸阀的可调吸引装置组成。设有一个阀，如果储气囊完全塌陷，该阀会向大气开放，从而在系统中产生轻微的真空。另一个阀，如果储气囊完全膨胀且系统中产生轻微正压时会打开。使用该系统时，“麻醉师呼吸区”中的氟烷浓度可忽略不计。
