  • a chassis having an electronic vaporizer, said vaporizer having a first anesthetic chamber retaining said first anesthetic agent and a second anesthetic chamber retaining said second anesthetic agent;

    a carrier gas input port in flow communication with said first anesthetic chamber and said second anesthetic chamber, a precision orifice and an electronic control valve corresponding to each of said chambers being downstream of said gas input port, each of said chambers having a conduit in flow communication with said carrier gas input port, each of said conduits extending into each of said chambers below an upper level of anesthetic agent, wherein said carrier gas passes through a porous diffuser near an end of said conduit and bubbles through said anesthetic agent;

    said chamber further comprising an anesthetic gas outlet port;

    an electronic touchscreen display for controlling carrier gas flow rate to said first anesthetic chamber and said second anesthetic chamber, said electronic touchscreen display further allowing control of concentrations of said anesthetic agent in an anesthesia to a patient by intermittently opening and closing of said electronic control valve;

    a circuit board having an input/output portion, said circuit board in electronic communication with said electronic touchscreen display, said input/output portion receiving temperature of said anesthetic agent;
