The disclosed invention relates to a decontaminant dispenser which may be used as a projectile. The invention also relates to a decontamination process using the decontaminant dispenser. The decontaminant dispenser may be thrown by hand, launched as an artillery shell or the payload for a missile, or dropped by an airplane into the area to be decontaminated. The dispenser may be placed in the area to be decontaminated. The decontaminant dispenser may be ruggedized for use in hostile environments such as those that may be anticipated for military applications.

The present invention provides a method of controlling a light output of a surgical lamp used for illuminating a surgical site. The surgical lamp includes a housing that defines an internal cavity. A light source is disposed within the internal cavity of the housing. The light source produces a light path and a light field at a surgical site that is remote from the housing. The method comprises providing a voltage sensitive device along the light path, the voltage sensitive device having light transmissive properties that change in response to a biasing voltage applied thereto, and applying a biasing voltage to the voltage sensitive device to achieve a desired light intensity at the surgical site.

摘要:
A processor for decontaminating devices is comprised of a chamber for holding devices and a circulation system to circulate a microbial decontamination fluid through the chamber. A water filtration system filters water used in the processor. The water filtration system has a water line connectable to a source of pressurized water. A water decontamination system fluidly communicates with the source of water and the processor. The water decontamination system has a water circulation path and a tank located within the water circulation path. Means are provided to circulate water along the water circulation path through the tank. A gas circulation path fluidly communicates with the tank. Conveying means is provided to convey gas along the gas circulation path through the tank. An ozone producing device is located along the gas circulation path to introduce ozone into gas flowing along the gas circulation path and through the tank.
摘要:
A method and apparatus for aerating a region exposed to a gaseous/vaporous sterilant. A catalytic destroyer and a reactive chemical unit are used to reduce the concentration of the gaseous/vaporous sterilant within the region. The reactive chemical unit includes a chemistry that is chemically reactive with the gaseous/vaporous sterilant. In one embodiment, the gaseous/vaporous sterilant is vaporized hydrogen peroxide and the chemistry of the reactive chemical unit includes thiosulfate and iodide.
摘要:
Hydrogen peroxide is vaporized (20) and mixed (30) with ammonia gas in a ratio between 1:1 and 1:0.0001. The peroxide and ammonia vapor mixture are conveyed to a treatment area (10) to neutralize V-type, H-type, or G-type chemical agents, pathogens, biotoxins, spores, prions, and the lip-,c. The ammonia provides the primary deactivating agent for G-type agents with the peroxide acting as an accelerator. The peroxide acts as the primary agent for deactivating V-type and H-type agents, pathogens, biotoxins, spores, and prions. The ammonia acts as an accelerator in at least some of these peroxide deactivation reactions.

摘要:
An oxidizing liquid (20), such as hydrogen peroxide, is vaporized (18) and the vapor is used to deactivate nerve gas, blistering gas, or other biologically active substances such as pathogens, biotoxins, and prions. A second chemical compound (42) in vapor, mist, or fog form is used in conjunction with the oxidizing vapor. In one embodiment, the second chemical preconditions the biologically active substances to be deactivated more efficiently by the oxidizing vapor. In another embodiment, the second chemical boosts the reactivity of the oxidizing vapor. In another embodiment, the other chemical reacts with the oxidizing vapor to form an intermediate compound that deactivates at least some of the biologically active substances.
摘要:
A method and apparatus for neutralizing biological and/or chemical warfare agents using an ozone-containing solution. The ozone-containing solution is produced by combining ozone-containing gas with an ozone vehicle, such as an organic solution. The ozone-vehicle prolongs the shelf life of the ozone to allow for extended periods of storage. A storage container is used to store the ozone-containing solution and facilitate its transportation to an environment contaminated by the biological and/or chemical warfare agents, or near a potential site for biological or chemical attack. The ozone-containing solution is drawn out of the storage container to apply it to a contaminated environment.
