Definitions

  • vaporization surfaces or elements of inhalation narcotic vaporizers are made of halogenated synthetic resins which are water repellent so that the surfaces do not become deactivated by films of water.
  • the fresh gas which consists mostly of oxygen or of nitrous oxide-oxygen mixtures, is withdrawn from pressurized bottles of the gas and, consequently, it is practically free of water vapor.
  • Vaporizers may find use only in combination with a metering device for each specific narcotic.
  • the object of the present invention is to provide means for the use of surface vaporizers within the narcotic circulation system of inhalation narcotic devices so that the surfaces do not become deactivated by films ofwater.
  • the essence of the present invention resides in the useofvaporization surfaces and elements, in inhalation narcotic devices, which are made of synthetic resins which have water repellent properties.
  • the water is depositedon such surfaces in beads and flows therefrom, but not, however, so as to flow into the storage container for the liquid narcotic.
  • the placement of the vaporizer inside the narcotic circulation system is so arranged that the circulation system is provided with threaded couplings, which do not match any of the parts of the usual narcosis devices with the exception of the threaded joints of the narcotic metering device and special reducers or' connectors of the narcosis device.
  • the devices of the present invention maybe'further explained by reference to the drawing which shows, in section, a narcotic vaporizer.
  • the vaporizer is fastened to other elements ofthe narcotic circulation system by means of screw or threaded members I and 2.
  • the narcotic metering device' is screwed into the'internally threaded member I.
  • threaded member 2 there may be screwed different juncture members for accomodating different types of narcosis devices, as for example, cones of different diameters of special threaded joints.
  • the vaporizer housing is divided into two concentrically running inner chambers 3 and 4.
  • Lower chamber 3 serves as a storage container for the liquid narcotic which is transported into upper vaporization chamber 4 by means of capillary force through several concentrically arranged porous rods 5 which are made of one of the water repellent synthetic resin materials referred to above.
  • a regulatable gas-current dividing flap 7 which is rotatable on an axle 8 may be so used as to either allowthe gas stream 10 entering from below to pass through the vaporization chamber 4 unhindered, as is shown in the drawing by the arrows depicting the flow of such gas stream, or the flap can be used to divert a por- 1 tion of the gas stream through vaporization. chamber 4 and allow theremainder of the stream to pass through the vaporizer without enteringthe vaporization chamber.
  • the regulating screw which is accessible from the outside of the vaporizer and which is used for the operation of a gas flow partitioning device is not shown.
  • a surface vaporizer for a narcotic circulation system comprising a narcotic liquid supply chamber. a vaporizing chamber having active vaporizing surfaces, and porous liquid
