Abstract

Equipment for use in the administration of respirable - e.g. anaesthetic - gases, designed to minimise pollution of the environment by spent gases. The outlet from the patient's mask 1 is connected, via a reservoir 10, to a vacuum source 11. In addition a gas flow line 9 connected to the vacuum source is provided, having an inlet 8 located by the mask so as to scavenge gases which issue into the surrounding atmosphere during gas administration. The system is particularly suitable for use in dental surgery, where a major source of pollution by spent gases is the patient's open mouth. <IMAGE>
