  • Publication number: 20190329009
    Abstract: A method for removing bodily fluid includes drawing bodily fluid that has accumulated in excess, converting the drawn fluid from bulk liquid form to aerosol form, and disposing of the aerosol via evaporation of liquid droplets and absorption and/or diffusion of vapor. Conversion from bulk liquid to aerosol may include collecting the bulk liquid fluid in a reservoir, conveying the bulk liquid bodily fluid to an atomizer, converting the bulk liquid fluid into an aerosol having ultrafine droplets, and ejecting the aerosol into a subcutaneous space for disposal via evaporation of liquid droplets and absorption and/or diffusion of vapors. The method may be performed with a subcutaneous atomizer that may be controlled locally or by an external transmitter for effecting a conversion and mist rate to keep pace with the accumulation of excess bodily fluid.

  • Patent number: 10238761
    Abstract: The present invention is an improved method for decontamination of a space and an integrated device that completes the decontamination cycle extremely fast while still being compact, lightweight, simple to operate and easy to move as a single unit. The method of the present invention delivers less biocide than is used in prior art methods at a very high rate of flux, allows the biocide to reside in the space being decontaminated to achieve a predetermined kill level, and then aerates the space. Because a nominal amount of biocide is used, there is less biocide to remove from the space than in prior art methods thereby reducing the time required for aeration and shortening the downtime for safe entry of the facility.

  • Patent number: 9533064
    Abstract: A mist generator is used to deliver a high throughput extremely fine mist comprising a biocide. Flows of evaporating hot gas mix turbulently and enhance forced heat and mass transfer between the very fine droplets and the hot gas to form a well-mixed premixed evaporator, resulting in high humidity vapor formation well inside a tube. The high relative humidity vapor with elevated temperature is then condensed as it exits the tube and disperses into the volume to be decontaminated as a condensed vapor cloud, but neither as a mist nor as a pure vapor depending on temperature and humidity of room environment. The condensed vapor cloud may evaporate or settle on the volume surfaces and contents, whereby both dry vapor and condensed vapor are applied into the volume for the killing process.

  • Patent number: 7834225
    Abstract: A method and device is presented for separating liquid mixtures using ultrasonic atomization and without subjecting the mixture to heat or thermal distillation. The process of ultrasonic separation does not involve liquid heating and saves up to 75% of the energy required as compared to thermal distillation. The method involves high throughput fixed bed atomizers with a specially designed carrier gas flow for aerosolization, extraction, and transport of mist. The mist richer in the desired component is then collected and condensed by electrostatic or other de-misting means. Repeated processes can achieve high separation efficiency. The efficiency of separation can be controlled by varying the ultrasonic frequency, power, and number of arrays, liquid surface tension and interfacial tension of mixtures.

  • Patent number: 7326382
    Abstract: A method of sterilizing a site or contained volume includes providing an aqueous biocide solution containing a biocide agent such as hydrogen peroxide. A mist of reactive biocide droplets is generated by atomization at ambient pressure from the biocide solution and a flow of carrier medium or air is provided in communication with the mist. The flow of carrier medium is controlled to generate a biocide mist comprising a concentration of stable mist droplets within the carrier medium. By controlling aersolization, extraction and delivery of the stable mist droplets, a sufficient portion of the stable mist droplets for a sterilizing treatment of a designated site do not coalesce prior to treatment interaction with the treatment site. The process of formation, stabilization and extraction are done in-situ so that droplets do not coalesce during transport.

  • Patent number: 7264773
    Abstract: The invention provides a method for generating a homogeneous aqueous mist solution containing a solvent such as water and a biocide agent such as chlorine dioxide, which would otherwise be unstable. The unstable biocide agent or chlorine dioxide is quickly dissolved or mixed with a mist of solvent causing the biocide agent to co-exist or co-mist therewith. The mist microencapsulates the biocide gas so that it does not decompose in the fumigation volume or space. The resulting homogenous mist solution provides a mist for delivering the biocide agent in a chemically stable form. Methods for mixing the separately generated mist and biocide gas include combining the mists in a Y-tube and then mixing the combination in a baffled mixing chamber, combining the mists in an area above their points of generation and then further mixing, and providing a series of mist generation units connected by a conduit for a carrier medium to pass to and connect the units and cause the mists to combine.

  • Patent number: 7090028
    Abstract: An improved method and apparatus for producing an extremely fine micron and sub-micron size water mist using an electronic ultrasonic device that produces the mist at ambient-pressure and delivering the mist for application in suppressing fire. A piezoelectric transducer is arranged to produce a water mist having at least a portion of sub-micron size droplets. The water mist is produced by high frequency pressure waves or ultrasonic waves of predetermined or variable frequency, including frequencies which may exceed 2.5 MHz. The water mist is directed to a firebase to be self-entrained by the fire's flame. The momentum provided the water mist in directing the mist is minimized to enhance the ability of the fire to entrain the mist, and the flow of the carrier medium is usually directed tangentially about the water fountain creating the mist. Further, the throughput and concentration of the mist is controlled to ensure that the entrained mist will be sufficient to cool and suppress the fire.

  • Patent number: 7004261
    Abstract: A fire suppressant, fire suppressant mist, and method of atomizing a water mist for suppressing a fire are provided by in-situ atomization of water droplets within a fire using water-in-oil microemulsions. The discrete phase of emulsion is a low boiling point oil or water immiscible fluid additive combined with water and a surfactant or cosurfactant. Each dropet provides a microemulsion. During the heating of the microemulsion droplet inside the flame, the water immiscible fluid vaporizes and causes fragmentation of the water droplet, producing extremely small droplets useful in fire suppression.

  • Patent number: 6955063
    Abstract: A cooling method and apparatus including a mist-generating device is configured to generate a mist of droplets from water, dielectric liquids or any cooling liquids. The mist is produced having such volume, momentum, concentration and quality of scale so as to deter or avoid impingement or deposition of the mist droplets on a surface to be cooled or on surfaces within a heat dissipating system to be cooled. Effective cooling is provided by the high latent heat of vaporization of water or other suitable fluid, while surfaces normally subject to possible damage by wetting are protected from harmful contact from the fluid. Tangential flow technology and electronic ultrasonic atomizing devices may be used as one possible means to generate the required mist and control mist volume, momentum, concentration and quality. Other variables may be controlled to enhance the cooling of the mist, such as flow patterns and flow directions of the mist. Vaporized mist may be condensed and recovered.

  • Patent number: 6883724
    Abstract: The present invention provides a method and device for production, extraction and delivery of an aerosol mist with ultrafine droplets. A high frequency wave generating device or other process generates very small particles or droplets from a reservoir of liquid or material to be atomized. A helical flow of a carrier gas medium such as air is directed into a container and creates a high throughput aerosol of air and fine droplets. The aerosol is delivered through a suitable outlet such as by deflecting the aerosol upwards and providing a tube centrally situated with respect to the helical flow such that the aerosol will discharge through the tube in high quantity of throughput and high quality of stable aerosol of very fine mist droplets. The methods described utilize in-situ extraction of fine mist droplets using helical flow behavior as opposed to forced convection ejection of mist or inertial separation of droplets by separators.
