An anesthetic vaporizer comprises a housing having a liquid reservoir and a vaporizing chamber over the reservoir. A gas inlet into the housing provides for flow through a vaporizing passage and into the vaporizing chamber for subsequent flow outwardly above the chamber, through an outlet vaporizing passage, to an outlet for discharge to the place of use. The vaporizing passage includes a spirally wound wick tube disposed between an interior wall of the housing and an interior barrel of cylindrical shape which retains the tube in position. In addition a bypass passage connects the inlet to the outlet passage and a control is provided for regulating the flow through at least one of the passages so as to regulate the amount of the circulated gas which is enriched with vaporized anesthetic. |
