We disclose a mask for administering a breathable gas to a patient, which comprises a mask body and a gas flow disrupter joined to the mask body for generating a turbulent gas plume rearwardly towards the nose and mouth of the patient. The mask body is configured to position the flow disrupter so as to be spaced from and opposing the patient's nose and mouth region when the mask is worn by the patient. The mask includes a gas inlet for admitting gas from an external source into the mask interior, through the gas flow disrupter. The gas flow disrupter can be configured to generate a turbulent gas plume wherein the velocity of gas exiting the disrupter is approximately the same as the gas velocity entering the mask from the gas inlet.

The invention provides an apparatus to retrofit existing anesthetic vaporizer canisters; said apparatus being adapted to be installed in the refill opening of a standard vaporizer canister and configured so that only one specifically assigned refill key index can be used to refill the canister in order to ensure that anesthetics are not inadvertently mixed or substituted in specifically designated vaporizer canisters.

Apparatus for use in refilling an anesthetic vaporizer

A control device for anesthetic vaporizers disclosed herein ensures that the operator is able to select a desired anesthetic with certainty, and to assure that other anesthetic vaporizer apparatus also in use is in an 'off' condition when one anesthetic has been selected. The apparatus also includes a setting at which all of a plurality of associated anesthetic vaporizers are safely 'off'. The invention comprises a rotatable rod adapted for mounting on an assembly of anesthetic vaporizer tanks, the rod having a plurality of C-collars thereon, the opening in each C-collar adapted to receive a flat spiral wing projecting from the on/off control on an anesthetic vaporizer. The C-collars also permit a setting at which it is impossible to open any of the associated anesthetic vaporizers. The control mechanism includes visual indicia as well as an audible indicator when a correct setting has been selected by the operator.
