摘要：Face mask for the administration of anaesthetics or oxygen. The mask includes a first tubular connector (4) through which anaesthetic gas can be supplied to the mask when ud in anaesthesia. A cond tubular connector (8) of smaller diameter is mounted co-axially within the first such that, alternatively, oxygen can be supplied to the mask through the cond connector. The cond connector is supported from the first by radial fins (9) and an annular passage (10) is formed between the first and cond connectors to admit atmospheric air into the mask when ud to supply oxygen and allow passage of expired gas to atmosphere. The two connectors (4 and 8) may conveniently be formed as a single moulding.
