| 20100034697 | MEMBRANE VAPOUR CONCENTRATOR - Apparatus for concentrating a vapor including an optional vaporizer, a vapor flow conduit; a counter flow conduit; and an optional humidity controller; wherein at least a portion of the vapor flow conduit and counter-flow conduit define respective opposed sides of a membrane. Also, a method of producing a concentrated active from a solution including an active in a solvent and having a first active-to-solvent ratio, the method comprising the steps of: (1) vaporizing the solution to form a vapor wherein the concentration of active is at about said first ratio, (2) providing a flow of the vapor to a first side of a membrane; and (3) providing an alternate flow of a gas to a second side of the membrane whereby to increase said first active-to-solvent ratio on the first side to a second active-to-solvent ratio greater than the first active-to-solvent ratio. | 02-11-2010 |
| 20080240981 | Membrane Sterilization - A method for disinfecting or sterilizing an article comprising enclosing the article or article part inside a container having a wall of which at least a part is a semipermeable fabric or membrane and introducing an amount of vaporizable biocide, preferably hydrogen peroxide in water, to the interior of said container in solution, vapour, liquid or preferably nebulant form. The semipermeable fabric or membrane is selected to allow the biocide to pass from inside to outside of the container as a vapour at atmospheric pressure and to provide a barrier against entry of micro-organisms. The biocide is allowed to exit the container through said membrane while at or above atmospheric pressure, a fluid eg air is directed to flow adjacent the outside of the membrane to expedite vapour removal from the interior side. The article is exposed to the biocide for a time sufficient to disinfect or sterilize the article. | 10-02-2008 |
| 20080223404 | Space Disinfection - A method for disinfecting a volume or surfaces bounding a volume comprising nebulizing a solution comprising a sterilizing agent in a solvent having a lower boiling point than the sterilizing agent, for example ultrasonic nebulization of aqueous hydrogen peroxide, to form a nebulant. The nebulant is subjected to energy of a kind and for a duration sufficient to vaporize solvent in preference to sterilizing agent, eg heating element means, infra red, laser, microwave, RF or other radiation generating means; induction heating means; heat exchanger means; conduction means; convection means; or mechanical energy transfer means to increase the concentration of the agent in the nebulant particles. Vaporized solvent is removed from the gas stream at or above atmospheric pressure and, if necessary, the nebulant is cooled to below 7O0C. The volume or surfaces are exposed to the nebulant for a time sufficient to sterilize said volume or surfaces. Also, apparatus for carrying out the method. | 09-18-2008 |
| 20080219884 | Aerosol - A nebulant suitable for sterilization comprising finely divided liquid droplets suspended in a gas, said droplets including a solute, which is advantageously hydrogen peroxide and a solvent, for example water, wherein the droplets have a concentration of greater than 60 wt % of solute and an average diameter of less than 1.0 micron, preferably less than 0.8 microns. Sterilization using the nebulant may be carried out in suitably adapted apparatus by nebulising a solution comprising a sterilizing agent in a solvent to form a nebulant of finely divided particles of the solution in a gas stream, said solution including a solvent having a lower boiling point than the sterilizing agent; subjecting the nebulant to energy of a kind and for a duration sufficient to vaporize solvent in preference to sterilizing agent, whereby to increase the concentration of the agent in the nebulant particles; removing the solvent vaporized from the gas stream at or above atmospheric pressure and, if necessary, cooling the nebulant to below 70° C.; and exposing a surface to be sterilized to the nebulant of concentrated sterilizing agent for a time sufficient to sterilize the surface. | 09-11-2008 |
| 20080199355 | Membrane Concentrator - Apparatus for concentrating a nebulant comprising a nebulant flow conduit and a counter-flow conduit, or preferably, a plurality of alternating nebulant flow conduits and corresponding counter-flow conduits eg in layered or coaxial arrangement, and wherein at least a portion of the nebulant flow conduit and said counter-flow conduits define respective opposed sides of a gas permeable membrane. In use a nebuliser is in communication with the nebulant flow conduit and the nebulant flow and counter-flow are in the same or opposite directions and act to concentrate the amount of active in a droplet eg from 35 wt % to 60 wt % hydrogen peroxide in water to disinfect and/or sterilize an article. | 08-21-2008 |
