ABSTRACT:
The present invention relates to an apparatus useful to controllably vaporize and mix a volatile anesthetic, having a vapor pressure of about 760 mm of mercury at about 20.degree. C., into an effective anesthetic/diluent gas mixture to be administered to a mammal. More specifically, the present invention is an apparatus, of interconnected components including anesthetic in a canister, diluent gas supply, flow meters, tubing connections, mixing carburetor, heating means, thermoelectric temperature control means, and the like. These components are maintained within a temperature controlled chamber such that the volatile anesthetic/diluent gas is effectively and controllably delivered to the patient. A preferred anesthetic is I-653, CF.sub.3 H--O--CFH--CF.sub.3.
