Receiving waste anesthetic gas in a chamber which is sent to a vacuum manifold on detection of the gas

摘要

Disclosed is a system for scavenging anaesthetic gas components from waste anaesthetic gas. The system comprises: a chamber (32) having an input and an output in fluid communication with each other; a selectively isolable flow path (34) having a first end portion fluidly coupled to the output of the chamber; and a detector (40) coupled to the chamber. The input of the chamber is coupled to an exhaust (18) of an anesthetizing machine (12) and receives waste anaesthetic gas therefrom which includes an anaesthetic gas component. The selectively isolable flow path has a second end portion adapted to be fluidly coupled to a vacuum manifold (16), the selectively isolable flow selectively isolating the chamber from the vacuum manifold. The detector coupled detects when the waste anaesthetic gas enters and is present in the chamber, the detector coupled to the selectively isolable flow path for control thereof. When the detector detects the gas, it causes the selectively isolable flow path to couple the output of the chamber to the vacuum manifold for evacuation of the gas the chamber into the vacuum manifold.
