Embodiment Construction

[0213] figure 2 A system 90 for capturing anesthetic halocarbons as detailed in P34906WO is shown.

[0214] Exhaust gas 38 from the anesthesia machine is passed via conduit 106 through connector 104 into tank 100 made of material resistant to supercritical pressure 103 . The canister 100 contains filter material 102 that captures the anesthetic agent from the exhaust 38 . The scrubbed gas then exits via exit conduit 108 and conduit 110 to pass through charcoal filter 120 before being vented to atmosphere 122 .

[0215] image 3 A system 200 for extracting and condensing anesthetic halocarbons trapped on a filter material using a supercritical fluid is shown in .

[0216] Trapping the anesthetic halocarbon onto the filter material 102, as in figure 2 or Figure 5 and Figure 6 as detailed in . exist figure 2 In , the tank is pressure-resistant and can therefore be connected directly to a supply of supercritical fluid. exist Figure 5 and Figure 6 In , the filter ma...

Abstract

An anaesthetic halocarbon capture system is provided. The system comprises a pressure-intolerant sleeve containing filter material for capturing one or more types of anaesthetic halocarbon prior to supercritical fluid extraction, and a pressure-tolerant housing into which the sleeve can be inserted so as to permit exposure of the sleeve contents to pressures required for supercritical fluid extraction.

Description

technical field [0001] The present invention relates to methods and improvements in the capture of halocarbon volatile anesthetics and their isolation and purification for resupply to consumers. This 'remanufacturing' approach aims to save financial and environmental costs. The invention also relates to methods and improvements in the synthesis of valuable anesthetics. Background technique [0002] Halocarbons are organic chemical molecules composed of at least one carbon atom covalently bonded to one or more halogen elements. Halocarbons have many uses and are used in several industries: solvents, pesticides, refrigerants, fuel repellants, components of elastomers, adhesives and sealants, electrical insulating coatings, plastics, and anesthetics. An alternative term for halocarbons is "halofluorocarbons" when the molecule includes halogen elements other than fluorine. [0003] Volatile anesthetics are typically halogenated fluorocarbons, examples of which include desflur...
