    Field of the Invention
    [0001] The present invention generally relates to decontamination systems, and more particularly to a decontamination system using cold mist to decontaminate a room or space. Background
    [0002] Decontamination methods are used in a wide range of applications and used in the same wide range of sterilizing agents. As used here, the term “decontamination” refers to processes, including, but not limited to, “biocontamination deactivation” and “sanitization”. Chemicals used to carry out decontamination are referred to without distinction here as decontaminants or sterilizers.
    [0003] In recent years, systems have been developed that use a cold mist from a sterilizer or decontaminant to disable rooms or spaces. Cold mist systems typically introduce an atomized or sterilizing decontaminant into a room or space to effect decontamination. Most of these systems tend to be simple and do not precondition the air inside the room or space before introducing the atomized or decontaminating sterilizer into it. With cold mist decontamination systems usually introducing a certain amount of sterilizer into a room or space based on the volume of the room or space and not taking into account the capacity of the air inside the room or space to retain the sterilizer. In this sense, the amount of the sterilant in a room or space can be retained without condensation of the sterilant on the surfaces inside the room or space is a function of the temperature and initial humidity level within the room or space. A problem with this system, particularly if it uses atomized hydrogen peroxide, is that the water has a higher vapor pressure than hydrogen peroxide. As a result, the droplets of atomized water will vaporize, that is, they evaporate more quickly in a quarter or space than the droplets of atomized hydrogen peroxide. Under certain conditions, liquid hydrogen peroxide having 5% hydrogen peroxide concentration may produce liquid droplets within the room or space having a 38% hydrogen peroxide concentration, which is very corrosive and highly flammable.
    [0004] The present invention provides a cold mist hydrogen peroxide decontamination system that optimizes a decontamination cycle by assessing environmental conditions within a room or space and introducing a mist of atomized hydrogen peroxide into the room or space in a room. level that does not condense on objects within the room or space. Summary of the Invention
    [0005] According to a preferred configuration of the present invention, a method of decontamination of a room or space is provided comprising the steps of: a) providing a cold mist decontamination device capable of generating an atomized mist comprised of a decontaminant and water from a liquid decontamination solution having a known concentration of the decontaminant therein, the decontamination system having an internal processor controlling the operation of the decontamination device; b) introduction into the internal processor of the parameters of the room or space and the concentration of the decontaminant in the decontamination solution; c) measurement of temperature and humidity in the room or space; d) determining the maximum amount of the decontamination solution that can be introduced into the room or space in atomized form without condensing the decontaminant on the surfaces within the room or space and determining the current amount of decontaminant in the maximum amount of the decontamination solution; e) determination of a period of time necessary to carry out a predetermined level of decontamination in the room or space based on the current amount of decontaminant that can be introduced in the room or space based on the empirical data stored within the controller; f) operation of the decontamination unit to introduce an atomized mist from the decontamination solution into the room or space; g) terminate the production of the atomized mist from the decontamination solution once the maximum amount has been introduced into the room or space; and h) provision of an indication when the time period has elapsed when the measurement of the atomized mist time production has ceased.
    [0006] An advantage of the present invention is a decontamination unit for the generation of a cold atomized mist from a water / hydrogen peroxide solution for the decontamination of a room or space.
    [0007] Another advantage of the present invention is the decontamination unit as described above which determines the maximum amount of a water / hydrogen peroxide solution that can be introduced into the room or space without condensing the hydrogen peroxide on the objects therein.
    [0008] An additional advantage of the present invention is a decontamination unit described above that determines an exposure time based on the maximum amount of hydrogen peroxide that can be introduced into a room or space.
    [0009] Another advantage of the present invention is a decontamination unit described above that can sterilize, sanitize, or disinfect a room or space.
    [00010] Yet another advantage of the present invention is a decontamination unit described above that can calculate the maximum amount of hydrogen peroxide that can be introduced into a room or space without condensing hydrogen peroxide on objects in it based on the parameters of the room or space, conditions within the room or space, and whether a sterilization, sanitization or disinfection procedure is to be performed.
    [00011] Another advantage of the present invention, is a decontamination unit described above that can detect the lowest temperature within a room or space and can calculate a maximum amount of hydrogen peroxide in the form of atomized cold mist that can be introduced into the room or space without condensing hydrogen peroxide on the objects in it.
    [00012] Yet another advantage of the present invention is a decontamination unit described above where the unit can detect the concentration of hydrogen peroxide within the water / hydrogen peroxide solution by means of a digitization code in a solution container of water / hydrogen peroxide.
    [00013] These and other advantages will become apparent from a detailed description of the invention, with respect to the attached drawings, presented in an exemplary and non-limiting manner, in which: Brief Description of Drawings
    [00014] The invention may take physical form in certain parts and harmonize the parts, as the preferred configuration in which it will be described in detail in the descriptive report and illustrated in the accompanying drawings that are part of it, in which:
    [00015] - Figure 1 is a partially sectioned elevated view schematically illustrating a decontamination unit for decontamination of a room or space with a cold atomized mist of hydrogen peroxide and water, illustrating a preferred configuration of the present invention. Detailed Description of the Preferred Configuration
    [00016] Referring now to the drawing where it is shown for the purpose of illustrating a preferred configuration of the invention only and not for the purpose of limiting it, Figure 1 shows a decontamination device 10, illustrating a preferred configuration of the present invention. The decontamination device 10 is designed to decontaminate a room or space using a cold mist sterilizer. As used here, the term decontamination refers to sterilization, disinfection, or sanitization.
    [00017] Sterilization refers to a process or method that makes a product free of all forms of viable microorganisms.
    [00018] Disinfection refers to a process or method that destroys diseases caused by pathogens or other harmful microorganisms but may not kill bacterial spores.
    [00019] Sanitization refers to a process or method that reduces bacteria by at least 99.9%.
    [00020] In the configuration shown, the decontamination device 10 is comprised of an external housing 12 which is generally rectangular in shape. The outer housing 12 includes an upper wall 14, a lower wall 16, and opposite side walls 22, 24. A panel is formed on the side wall 22 to allow access to the interior of the outer housing 12. Wheels or castors 28 are provided under the wall bottom 16 to allow the decontamination device 10 to be easily carried along a surface of a floor, designated 32 in Figure 1. An internal housing 42, disposed inside the external housing 12, defines a mist generation chamber 44. In the configuration shown, the mist generating chamber 44 is generally cylindrical in shape and includes an open upper end 46 which is attached to the upper wall 44 of the outer housing 12 and defines an opening 48 through the upper wall 14 of the outer housing 12. One Duct 52 is connected to the lower end of the inner housing. Duct 52 defines an internal passage 54 that communicates with the mist chamber 44 through an opening in the lower part of the internal housing 42. The passage 54, defined by duct 52 communicates with the outside of the external housing 12 through an opening 56 on the side wall 24. In this sense, a “P” path is defined through the outer housing through the passage 54 through the duct 52 and through the mist chamber 44 defined by the inner housing 42. The upper end of the inner housing 42 is formed to have an upwardly extended flange or collar part 62 that defines the annular surface 64.
    [00021] A fog device 92 is provided inside the fog generating chamber 44. An air line 94 connects the fog device 92 to an air compressor 96 which is arranged inside the outer housing 12. A line of air decontamination 112 connects the mist device 92 to a source 114 of decontaminant. In the configuration shown, the source 114 of the decontaminant is a container containing a liquid decontamination solution 118. A siphon tube 122 extends into the liquid decontamination solution 119 inside the container 116, The siphon tube 122 is connected by a plug connector 124 to the decontamination line 112. As will be described in more detail below, container 116 is identified by a bar code 126. In the configuration shown, a bar code is provided on container 116. Bar code 126 provides information encoded with respect to composition and concentration of decontamination solution 118 retained in container 116. In a preferred configuration, decontamination solution 118 is a solution of water and hydrogen peroxide.
    [00022] A metering pump 132 is disposed within the decontamination line 112 at the predetermined meter of the amounts of decontamination solution 118 from the container 112 to the mist device. A pump motor 134 directs the metering pump 132. In the configuration shown, the mist device 92 is comprised of a conventional nozzle 136 enabled to create mist when the liquid decontamination solution 118 pumped by pump 132 from container 116 is combined with air compressed air compressor 96.
    [00023] A blower fan 142 is provided inside the passage 64 to carry the outside air of the outer housing 12 through the mist generation chamber 44. A fan motor 144 is connected to the blower fan 142 to direct it.
    [00024] A controller 152 is provided to control the operations of the dosing pump motor 134 and fan motor 144. A temperature sensor 154, an infrared temperature sensor 156, a humidity sensor 158, a hydrogen peroxide sensor 159 and a directional laser sensor 162 are provided to determine certain parameters within the room or space to be decontaminated. Temperature sensor 154 is connected to controller 152 and being operated to provide signals to controller 152 indicative of the temperature within the room or space surrounding the decontamination device 10. Infrared sensor 156 is connected to controller 152 and being operated to provide indicative signals temperature in different regions of the room or space. Humidity sensor 158 is connected to controller 152 and provides signals indicative of humidity within the room or space to be decontaminated. The hydrogen peroxide sensor 159 is connected to controller 152 and being operated to provide signals to controller 152 indicative of the level of hydrogen peroxide in the room or space. Laser sensor 162 is connected to controller 152 and being operated to provide indicative signals the dimensions of the room or space within which the contamination device 10 is positioned. A sensor 164 is further provided to read bar code 126 in decontamination container 116. As indicated above, the bar code is provided in decontamination container 116 to provide information regarding decontamination solution 118 within container 116. accordingly, sensor 164 is positioned adjacent to the storage position for decontaminating container 116 to provide signals to controller 152 indicative of the contents of decontaminating container 116. A power cable 172, connected to one end of controller 152, extends across from the side wall 22 of the external housing 12. The power cable 172 includes a conventional plug 174 on the free end of it to connect to the standard electrical outlets within the room or space to be decontaminated to provide power operation to the decontamination device 10. As will be appreciated, the decontamination device 10 may contain an internal energy source, such as a the battery to provide the operation of energy to the various components contained therein. An input display panel 176 is provided on the outside of side wall 22 of the outer housing 12. The input display panel 176 is connected to controller 152 and allows users of decontamination device 10 to enter information into controller 152. O input display panel 176 may also display information regarding the operation of the decontamination device 10, such as the conditions of the operation.
    [00025] A method of operating the decontamination device 10 will now be described. Before carrying out a decontamination procedure, the container 116 containing a decontamination solution 118 is inserted into the decontamination device 10 through the access panel 26 on the side wall 22 of the decontamination device 10. In accordance with an aspect of the present invention, the decontamination solution 118 may be a sterilization solution, a disinfection solution, or a sanitization solution. Accordingly, each type of solution has a specific identification bar code 126 associated with it applied to container 116 to identify the type of solution contained within container 116. In addition to identifying the type of active ingredient in decontamination solution 118, bar code 126 in container 116 further identifies the concentration of the active ingredient within the decontamination solution 118.
    [00026] Container 116 is placed inside the outer housing 12 so that bar code 116 is positioned close to sensor 164 where the bar code on container 116 can be entered and read by sensor 164. Based on the signals provided by sensor 164, controller 152 will be able to identify the contents of container 116, specifically, the type of active ingredient (the decontaminant), that is, a sterilizer, a disinfectant or a sanitizer, as well as the concentration of the decontamination within the decontamination solution 118 in container 116. As will be described in more detail below, controller 152 is programmed to operate in three modes, notably a sterilization mode, a disinfection mode or a sanitization mode. By identifying the contents of the container 116, the controller 152 is enabled to confirm that the appropriate decontamination solution 118 is present in the decontamination device 10 in order to carry out a desired decontamination operation.
    [00027] During the operation of the decontamination device 10, the liquid decontamination solution 118 is monitored to the mist device 92 by the operation of the dosing pump motor 134. The controller controls the speed of operation of the pump motor 134 to control the quantity of the decontamination solution 118 introduced in the mist device positioned in the mist generation chamber. The decontamination solution 118 is introduced into a compressed air path that is introduced into the mist device 92 by the air compressor 96 through the air line 94. The introduction of the liquid decontamination solution 118 and the compressed air into the mist nozzle 136 in the mist device 92 create an atomized mist from the decontamination solution 118 in the mist generation chamber 44. At the same time as the mist device 92 is creating a mist, the controller operates the fan motor 144 to motivate the blower fan 142 to carry external air through the passage 54 of the duct 52 and through the mist generation chamber 44. The air flow through the mist generation chamber 44 collects the atomized decontaminating mist and injects it into the room or space.
    [00028] In accordance with an aspect of the present invention, controller 152 is programmed to control the operation of the metering pump motor 134 and the fan motor 144 to introduce a predetermined amount of decontaminant into the room or space in the form of an atomized mist . The amount of decontaminant introduced in the room or space is based on the parameters of the room or space as well as the conditions inside the room or space, mainly the temperature and humidity inside the room or space.
    [00029] According to the present invention, controller 152 is programmed to operate the decontamination device 10 in order to introduce a desired amount of decontamination solution 118 as an atomized mist into the room or space based on the type of decontamination procedure selected . In this regard, controller 152 is programmed to operate in three modes: a sterilization mode, a disinfection mode or a sanitization mode. One of these three operating modes is selected by the user using a display input pad 176. Once an operating mode has been selected, controller 152 determines certain parameters with respect to the room or space. Parameters related to temperature, humidity and size of room or space can be entered using the input display panel 176. Alternatively, this information can be determined using sensors 154, 156, 158, 162 that form part of the decontamination device 10. In this In this sense, the temperature sensor 154 provides an indication of the temperature within the room or space. Humidity sensor 158 provides information to controller 152 regarding the level of humidity within the room or space. The directional laser sensor 162 can provide an indication of the parameters of the room or space, mainly the distance between the walls and the ceiling and the floor to provide a volume within the room or space. Cold points, regions or areas within the room or space can be determined using an infrared sensor 156. In this sense, as will be appreciated in the reading of this specification, calculations related to the amount of decontaminant that can be introduced in the room or space will be determined based on the sterilizing liquid on surfaces in the room or space will be more likely to occur. Controller 152 also determines the current amount of the active decontaminant within the decontaminating solution 118. This information can be entered into the decontamination device 10 using input display panel 176, or sensor 164 disposed adjacent to container 116 being able to determine the contents of container 116 based on bar code 126 that identifies the contents of container 116. Knowing the parameters of the room or space, as well as the characteristics of temperature and relative humidity within the room or space, and also knowing the current amount of the active decontaminant, that is, sterilizing, disinfectant, or sanitizer within decontamination solution 118, controller 152 determines the maximum amount of decontamination solution 118 that can be introduced into the room or space without causing condensation of decontamination solution 118 to surfaces within the room or space. This determination of the maximum amount of the decontamination solution 118 can be introduced in the room or space being based on the empirical data stored inside the memory of the controller 152.
    [00030] Having determined the maximum amount of decontamination solution 118 that can be introduced in the room or space, controller 152 determines the time required to carry out the selected decontamination level, mainly, sterilization, disinfection or sanitization, based on the current amount of the product. sterilizing, disinfectant or sanitizer that can be introduced into the room or space. The controller 152 then initiates the operation of the decontamination device 10 to introduce the atomized mist of the decontamination solution 118 into the room or space. The operation of the decontamination device 118 was introduced in the room or space. Once the production of the atomized mist has ceased and the time required to decontaminate the room or space has elapsed, controller 152 provides an indication that the predetermined exposure time limit required to effect the desired level of decontamination has been completed. At this point, controller 152 may be connected to a destructor device to initiate the operation of a destructor unit (not shown) to destroy any sterilizing vapors or disinfectant vapors that may still be present in the room or space. Alternatively, controller 152 may be programmed to determine a "dissipation period". The dissipation period is the time within which the vapors in the room or space will be dissipated or destroyed. Thus, controller 152 may provide an indication that the room or space is safe to be occupied by humans.
    [00031] The present invention incorporates a template control system. The template control will allow the controller to calculate the dew point in the room based on temperature, relative humidity and hydrogen peroxide concentration. To prevent condensation on the coldest surface, the lowest temperature is measured with the 156 infrared sensor. The dew point is programmed with the “D” valve that considers hydrogen peroxide and water levels (concentration and saturation) to determine contact time.
    [00032] The present invention thus provides a simple decontamination and a method of using it to automatically sterilize, disinfect or sanitize a room or region.
    [00033] The above description is a specific configuration of the present invention. It should be appreciated that this configuration is described for purposes of illustration only, and numerous changes and modifications may be practiced by a person skilled in the art with knowledge of the state of the art without departing from the spirit and scope of the invention. It should be understood that all such modifications and alterations may be included as long as they are within the scope of the invention as claimed or equivalent to it.
