Publication number: 20200390923Abstract: The present invention relates to the detection vapor peracetic acid and hydrogen peroxide. It finds particular application in the sensing of vapor peracetic acid and hydrogen peroxide concentrations. The system includes (a) a source of peracetic acid vapor, hydrogen peroxide vapor, water vapor and acetic acid vapor, (b) a light source which is configured to supply light with at least a component in the mid-infrared range, and (c) a detector which is configured to individually detect mid-infrared range light in (i) a first mid-infrared spectrum absorbed by the peracetic acid vapor and not absorbed by the hydrogen peroxide vapor, the acetic acid vapor or the water vapor, and (ii) a second mid-infrared spectrum absorbed by the peracetic acid vapor and the hydrogen peroxide vapor.Type: ApplicationFiled: December 20, 2018Publication date: December 17, 2020Inventors: John Matta, Kristopher Murphy, Huyen Bui, Tuan Nguyen, Sherly Bellevue Faye, Mason Schwartz, Ted Bahns, Lisa Bourdon

Patent number: 9511162Abstract: A method for disinfecting a room includes generating a fog from an enclosure having first and second air inlets and an air dispersion outlet including a fan configured to draw air into the enclosure through first and second air inlets and to force air out of the enclosure. A filter assembly is disposed relative to the second air inlet such that air that flows between the exterior and interior of the enclosure through the second air inlet passes through the filter assembly. The method further includes actuating an air intake assembly, activating the fan, actuating the air intake control assembly, and deactivating the fan.Type: GrantFiled: November 17, 2014Date of Patent: December 6, 2016Assignee: MAR COR PURIFICATION, INC.Inventors: Mason Schwartz, Thomas M. Gentle, Jr., Michael P. Petersen

Patent number: 9439991Abstract: A method for decontaminating a medical device includes enclosing the medical device in an enclosure including a fog-permeable layer and an exterior port member coupled to the fog-permeable layer. The exterior port member of the enclosure is coupled to a chemical dispersing interface in a decontamination chamber. A pressure in the decontamination chamber is reduced to a sub-atmospheric pressure in a first evacuation step. A room temperature decontaminating fluid is introduced as a fog into the decontamination chamber. The fog is held in the decontamination chamber for a decontaminating time. The pressure in the decontamination chamber is reduced to a sub-atmospheric pressure in a second evacuation step. The decontamination chamber is vented to atmospheric pressure.Type: GrantFiled: August 29, 2014Date of Patent: September 13, 2016Assignee: MEDIVATORS INC.Inventors: Mason Schwartz, Jonathan K. Olson, Thomas M. Gentle, Jr., John E. Marxer, Michael P. Petersen

Patent number: 9402929Abstract: A system for decontaminating a device, such as a medical device, includes a decontamination chamber configured to retain the device and a chemical dispersion assembly configured to deliver a decontaminating fluid to the decontamination chamber. A pressure control assembly is connected to the decontamination chamber and configured to control the pressure in the decontamination chamber. The system also includes a system controller configured to control the decontamination chamber, chemical dispersion assembly, and pressure control assembly. A decontaminating fluid is added into the decontamination chamber at a first rate while increasing the pressure in the decontamination chamber. Adding the decontaminating fluid increases a relative humidity in the decontamination chamber.Type: GrantFiled: March 30, 2015Date of Patent: August 2, 2016Assignee: MAR COR PURIFICATION, INC.Inventors: Mason Schwartz, Jonathan K. Olson

Patent number: 9017607Abstract: A system for decontaminating a medical device includes a decontamination chamber configured to retain the medical device and a chemical dispersion assembly configured to deliver a decontaminating fluid to the decontamination chamber. A pressure control assembly is connected to the decontamination chamber and configured to control the pressure in the decontamination chamber. The system also includes a system controller configured to control the decontamination chamber, chemical dispersion assembly, and pressure control assembly. A pressure in the decontamination chamber is reduced to within a sub-atmospheric pressure range in a first evacuation step and add a decontaminating fluid into the decontamination chamber at a first rate while increasing the pressure in the decontamination chamber. Adding the decontaminating fluid increases a relative humidity in the decontamination chamber to a level that improves the efficacy of the decontaminating fluid.Type: GrantFiled: May 23, 2012Date of Patent: April 28, 2015Assignee: Medivators Inc.Inventors: Jonathan K. Olson, Mason Schwartz

Patent number: 8889081Abstract: A system for disinfecting a room includes an enclosure having first and second air inlets and an air intake control assembly to selectably control air flow into the enclosure through the first and second air inlets. Air that flows between the exterior and interior of the enclosure through the second air inlet passes through a filter assembly. The enclosure also includes an air dispersion outlet having a fan that draws air into the enclosure through the first and second air inlets and forces air out of the enclosure. A chemical dispersion assembly generates a disinfecting fog relative to the fan. A system controller controls the air intake control assembly to disperse the disinfecting fog into the room, and subsequently draw the disinfecting fog from the room and through the filter assembly.Type: GrantFiled: October 14, 2010Date of Patent: November 18, 2014Assignee: Medivators Inc.Inventors: Mason Schwartz, Thomas M.
