20150265738 | SATURATION-ENHANCED, LOW-CONCENTRATION VAPORIZED HYDROGEN PEROXIDE DECONTAMINATION METHOD - A method for decontaminating an object disposed in a region. The method includes the steps of: heating the region to a target temperature; introducing steam into the region until a humidity level in the region reaches a target humidity level; introducing a vaporized sterilant into the region until a sterilant concentration in the region reaches a target sterilant concentration; and maintaining the target temperature, the target sterilant concentration and the target humidity level until a predetermine target dose is obtained. | 09-24-2015 |
20150239018 | MOVABLE RACK ASSEMBLY WITH CORNER SPRAY NOZZLES - A movable rack assembly for a washer having a generally rectangular frame. The frame includes a central hub connectable to a fluid source. A plurality of elongated tubular base members extends from the central hub and defines a bottom of the frame. A pair of spaced-apart elongated, tubular side members defines side portions of the frame and a space therebetween. Each of a plurality of spaced-apart transverse members has ends that are connected to one of the side members. The transverse members transverse the space defined between the side members. A rotary spray arm is attached to each of the transverse members. A plurality of corner spray nozzles on the frame directs fluid toward corners of the frame. The bottom members, the side members and the transverse members are fluidly connected with each other and fluidly connect the rotary spray arms and the corner spray nozzles with the central hub. | 08-27-2015 |
20140294670 | TRANSPORTABLE VACUUM ASSISTED DECONTAMINATION UNIT AND DECONTAMINATION PROCESS - The disclosed invention relates to a portable, vacuum assisted decontamination unit. The invention also relates to a vacuum assisted decontamination process. The decontamination unit may be ruggedized for use in hostile environments such as those that may be anticipated for military applications. | 10-02-2014 |
20140255012 | VAPORIZER WITH SECONDARY FLOW PATH - A vaporizer for generating a vaporized chemical decontaminating agent. The vaporizer includes a primary flow path and a blower for conveying a carrier gas along the primary flow path. A secondary flow path has a first end fluidly connected to the primary flow path at a location upstream of the blower and a second end fluidly connected to the primary flow path at a location downstream of the blower. A heating element is disposed along the secondary flow path. A liquid flow path has a first end fluidly connected to a source of liquid chemical decontaminating agent and a second end fluidly connected to the secondary flow path. The liquid flow path injects the liquid chemical decontaminating agent into the secondary flow path at a location upstream of the heating element. The heating element vaporizes the liquid chemical decontaminating agent to form the vaporized chemical decontaminating agent. | 09-11-2014 |
20140242717 | METHOD AND APPARATUS FOR OPTICAL DETECTION OF BIO-CONTAMINANTS - A method and apparatus for optical detection of residual soil on articles (such as medical instruments and equipment), after completion of a washing or a rinsing operation by a washer. A soil detection system provides an indication of soil on the articles by detecting luminescent radiation emanating from the soil in the presence of ambient light. | 08-28-2014 |
20140150827 | WASHER / DISINFECTOR HAVING A WATER INLET DIFFUSER - A washer having a plurality of water inlet diffusers, each diffuser connected to a water inlet line for directing the flow of fluid into the washing chamber. The water is directed, i.e., sprayed against the surfaces of the washing chamber to modify (adjust) the temperature of the washing chamber gradually prior to the start of a particular phase of a washing cycle. | 06-05-2014 |
20130177477 | DECONTAMINANT DISPENSER SUITABLE FOR USE AS A PROJECTILE - 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. | 07-11-2013 |
20100034707 | Integrated decontamination/aeration system for vehicles - An integrated duct system is utilized to admit an antimicrobial vapor into a vehicle to decontaminate the contents and surfaces of the vehicle and subsequently to remove the vapor. The ducts comprise an air conditioning and/or heating duct, a decontamination duct for admitting an antimicrobial vapor, an auxiliary circulation duct for diffusing the vapor throughout the vehicle, and an aeration duct for removing the vapor from the vehicle, as well as a catalytic converter for detoxifying the antimicrobial vapor before removal. The integrated decontamination system is suitable for the chemical or biological decontamination of vehicles, provides enhanced vapor delivery and distribution on a rapid basis and also provides for rapid aeration for removing the antimicrobial vapor. | 02-11-2010 |
20080199903 | Biological indicator - A biological indicator for monitoring the effectiveness of a sterilizing, disinfecting, etc., compound or condition is disclosed which comprises a substrate having a surface layer containing functional groups thereon desirably free of silicone linking groups. The functional groups are desirably in the form of a monolayer of a uniformed distribution and of a selected quantity. Various types of microorganisms such as spores and/or etiological agents are covalently bonded to the surface layer functional groups through a crosslinking reagent and thus form a uniform number and distribution of the microorganisms and/or etiological agents. After being subjected to sterilization or other similar treatment, etc., along with various articles such as instruments, the indicator can be cultivated to determine the effectiveness of the sterilization, disinfection, etc. process. | 08-21-2008 |
