Embodiment Construction

[0023] figure 1 An example vaporization system 20 is shown schematically. Vaporization system 20 facilitates vaporization of a liquid agent, such as a liquid anesthetic, into a carrier gas supplied to the patient's lungs. As will be described below, vaporization system 20 may be less expensive, more compact, require less heat, and be more responsive than many existing vaporization systems. Vaporization system 20 generally includes vaporizer 22 including flow channel 24 , porous vaporization element 30 and dispersion mechanism 34 , flow source 50 , and patient breathing apparatus 80 . In one embodiment, vaporizer 22 comprises a self-contained unit, cartridge or module configured to be connected or plugged into an existing framework supporting flow source 50 and / or patient breathing apparatus 80 . In another embodiment, vaporizer 22 may be incorporated into an overall assembly that includes flow source 50 and / or patient breathing apparatus 80 .

Abstract

An apparatus and method utilizing a porous vaporization element with a dispersion mechanism to disperse a liquid formulation onto the porous vaporization element. The porous vaporization element extends across a substantial portion of the cross-sectional area of ​​the flow channel. In one embodiment, the liquid formulation is sprayed onto the porous vaporization element.

Description

technical field [0001] The present invention relates to medical vaporizers with porous vaporization elements. Background technique [0002] Agents such as anesthetics are often administered to patients through the respiratory system to the patient's lungs. Such formulations are sometimes provided as a liquid that is vaporized in a medical vaporizer and delivered by a carrier gas to the patient's lungs. Existing vaporization systems are expensive, take up considerable space, require substantial heat input and suffer from slow on / off response times. Contents of the invention [0003] An apparatus is provided comprising a vaporizer comprising: a flow channel through which a carrier gas can flow; a porous vaporization element extending across a substantial portion of the cross-sectional area of ​​the flow channel; and a dispersion mechanism for A liquid formulation is dispensed onto the porous vaporization element. [0004] Also provided is an apparatus comprising a cartrid...
