摘要： The compact combination oral suction and scavenging apparatus can be operated simultaneously or separately for oral suctioning and expired anaesthetic gases scavenging of a patient under sedation. It includes a main shut off valve for turning the entire apparatus on or off, and a separate shut off valve which can be operated selectively to disable the scavenger portion of the apparatus. A safety relief valve prevents sub-atmospheric or excessively high pressures from building up in the apparatus to affect the normal breathing pattern of a patient. The expiratory valve of the scavenging assembly is housed in a disposable chamber having a disposable transparent snap-on dome shaped cover such that the expiratory valve can be readily monitored visually, and the cover can be easily and quickly removed for manual manipulation or adjustment of the expiratory valve by the anaesthetist.
