An anesthesia scavenging hood is adapted to fit over the head of a surgical patient and to prevent the contamination of operating rooms with waste anesthetic vapor and nitrous oxide gas. The hood enables placement of an endotracheal tube or other breathing or anesthesia circuit into the patient's airway. The hood may be sealed about the endotracheal tube and about the patient. The hood also includes a port having disposed therein a suction tube which communicates waste vapor and gas out of the hood and outside of the operating room with the aid of a vacuum source.

[ What is claimed is:] [1.] An anesthesia vapor scavenging device, comprising:an enclosure means for placement over at least a portion of a patient's head to isolate the patient's head from the environment adjacent to the enclosure means and to prevent the escape of anesthesia vapor from the environment within the enclosure means, the enclosure means having an open bottom portion, and being formed of a gas impermeable, plastic film;closure means for closing said open bottom to form a seal about the patient's neck;a first opening means disposed in the enclosure means for accommodating an anesthesia circuit fitting directly communicating with a patent's airway;a second opening in the enclosure means, andan elongate conduit extending through the second opening and into the enclosure means, the conduit having a plurality of perforations at a position on the conduit disposed within the enclosure means and approximately adjacent a patient's face and being sealingly engaged with the second opening such that the conduit is effective to communicate a vacuum force to the interior of the enclosure means and to remove gases from said interior.
