The Waste Gas Scavenger is designed for use with vacuum (suction) waste gas disposal systems with anesthesia machines and heart/lung bypass machines.

Active Waste Gas Scavenger

The Passive Waste Gas Scavenger is intended to be used for the scavenging of waste anesthetic gases from anesthesia machines used during the provision of general anesthesia to adults and children. The Passive Waste Gas Scavenger is designed for use with non-recirculating waste gas disposal systems and is intended for prescription use only.

The Passive Waste Gas Scavenger is intended to be used for the scavenging of waste anesthetic gases from anesthesia machines used during the provision of general anesthesia to adults and children. The Passive Waste Gas Scavenger is designed for use with non-recirculating waste gas disposal systems and is intended for prescription use only. This scavenging approach relies on the pressure of the waste gas to transfer the gas from the scavenger to the exhaust system. The scavenger body incorporates one 30mm/27mm/19mm horizontal hose terminal to connect the scavenger to the anesthesia machine. The vertically oriented 30mm/19mm hose terminal is intended to connect the scavenger to the exhaust system. The G. Dundas Passive Scavenger incorporates the same safety systems as predicate devices, providing relief of excess positive pressure and excess negative pressure to the patient through the use of pressure relief valves, in compliance with ASTM 1343-02 -Anesthetic Equipment -- Scavenging Systems for Anesthetic Gases. Although there is no standard for passive waste gas scavenging systems, the G. Dundas Passive Scavenger is designed to fail safe under active waste disposal conditions. The G. Dundas Passive Scavenger and the predicate devices were tested and found to have similar performance. Testing procedures and data can be found in Section 7 of this application.
