Description

Control system that remotely monitors disinfection/sterilization of enclosed spaces {Control system that remotely monitors disinfection/sterilization of enclosed spaces}

The present invention relates to a control system that remotely monitors sterilization/sterilization of confined spaces, and more particularly, quickly and safely sterilizes/sterilizes hospital operating rooms, emergency rooms, clinical laboratories, and confined spaces requiring sterilization/sterilization. It relates to a control system for remotely monitoring sterilization/sterilization of an enclosed space, which measures the concentration of hydrogen peroxide that sterilizes/sterilizes an enclosed space, and allows an operator to monitor and verify the measured value.

In general, sterilization refers to an aseptic state in which all kinds of microorganisms (bacteria, viruses, fungi, etc.) including spores are completely removed, and disinfection destroys or weakens the vitality of microorganisms to prevent infection and It can kill vegetative cells of microorganisms by eliminating proliferation, but it cannot destroy highly resistant spores.

In particular, spaces such as hospital operating rooms, emergency rooms, and clinical laboratories must be maintained in a sterile state without pathogens or other microorganisms at all, and microorganisms are prevented from approaching in special areas such as surgical areas. Most spaces such as operating rooms, emergency rooms, and clinical laboratories in hospitals adopt a wet sterilization method that automatically sprays ultra-fine hydrogen peroxide to sterilize the space. It is converted and sterilized by spraying the space for a certain period of time.

When using a sterilizing liquid such as hydrogen peroxide (H2O2), in principle, it is regulated to use a concentration of 6% hydrogen peroxide, but for some products, a concentration exceeding the specified value, for example, 35% hydrogen peroxide The current situation is to sterilize the space by using it. Although the sterilization effect can be improved by using high concentration of hydrogen peroxide, since hydrogen peroxide itself is treated as a toxic substance that is fatal to the human body, when a person is exposed to such a high concentration of hydrogen peroxide, it is likely to lead to a fatal respiratory disease.

In addition, in the case of the wet sterilization method, after spraying the sterilization solution, it takes a long time (approximately 2 to 3 hours) until the sterilization solution completely disappears, and the sterilization state in the space cannot be accurately known. Therefore, in order to solve this problem, it is necessary to develop a technology capable of checking the concentration value of hydrogen peroxide in real time.

Hereinafter, specific embodiments will be described with reference to the accompanying drawings.

1 is a block diagram of a control system for remotely monitoring sterilization/sterilization of an enclosed space according to an embodiment of the present invention.

Referring to FIG. 1, a control system 100 for remotely monitoring sterilization/sterilization of an enclosed space according to an embodiment measures and monitors the concentration of a disinfectant/sterilant sprayed into the enclosed space, and is a sterilization/sterilization device. (110), spray amount control unit 120, concentration measurement unit 130, operation determination unit 140, monitoring unit 150 may be included.

The sterilization/sterilization device 110 may be a device that sterilizes/sterilizes an enclosed space by spraying a disinfectant/sterilizing agent into the enclosed space. Here, the closed space may include a hospital operating room, an emergency room, a clinical laboratory, and a space requiring sterilization/sterilization. In some embodiments, the disinfectant/sterilizer includes hydrogen peroxide, chlorine dioxide, ozone, and the like, and the disinfectant/sterilant described below may be limited to hydrogen peroxide.

Also, in some embodiments, the sterilization/sterilization device 110 may include a solution storage unit 111 and a solution spray unit 112 .

The solution storage unit 111 may be a container for storing a hydrogen peroxide solution. In some embodiments, the solution storage unit 111 may include an outer body accommodating a container.

The solution spray unit 112 may be a spray nozzle for spraying a hydrogen peroxide solution.

In some embodiments, the sterilization/sterilization device 110 may further include an air injection unit 113. The air injection unit 113 may inject air into the solution spray unit 112 . In some embodiments, the air injection unit 113 may introduce external air by rotation of a fan and supply the solution to the spraying unit 112 . In some embodiments, the air injection unit 113 may further include a filter unit 114. The filter unit 114 is installed at the front end of the air injection unit 113 to filter external air, and can be replaced if necessary.

The solution sprayed from the spray nozzle, that is, hydrogen peroxide may be sprayed in a dry-fog state, that is, in the form of a hydrogen peroxide aerosol. Here, the particle size of the hydrogen peroxide sprayed in a dry state may be 10 to 20 μm. However, it is not limited thereto, and the particle size of hydrogen peroxide may be 10 μm or less. In addition, when the hydrogen peroxide solution is sprayed by injecting air into the hydrogen peroxide sprayed from the spray nozzle, it can be prevented from bursting even when they collide with each other. This may be because the larger the particles of hydrogen peroxide to be sprayed, the more residual moisture is generated when they collide with each other.

The spray amount control unit 120 can control the amount of hydrogen peroxide sprayed from the sterilization/sterilization device 110, that is, the solution spray unit 112. In some embodiments, the spray amount control unit 120 may spray in multiple stages by controlling the amount of hydrogen peroxide sprayed from the solution spray unit 112 with the wireless remote controller 190 described below.

The concentration measurement unit 130 may measure the concentration of hydrogen peroxide sprayed from the sterilization/sterilization device 110, that is, the solution spray unit 112. In some embodiments, the concentration measurement unit 130 may be a concentration measuring sensor that is fixed to one side of the sterilization/sterilization device 110 and measures the concentration of hydrogen peroxide sprayed into the closed space. The concentration of hydrogen peroxide measured by the concentration measuring sensor may be wirelessly transmitted in real time to the monitoring unit 150 described below.

The work determination unit 140 may determine whether to work in an enclosed space according to the concentration of hydrogen peroxide measured by the concentration measuring unit 130 . In some embodiments, the operation determination unit 140 can safely monitor the concentration value of hydrogen peroxide displayed as a numerical value or a graph in the monitoring unit 150 through the concentration measurement unit 130 without entering the closed space. That is, it can be determined that work in an enclosed space is possible only when the concentration value of hydrogen peroxide sprayed into the confined space is less than a predetermined reference value, and if the concentration of hydrogen peroxide sprayed into the confined space is greater than the predetermined reference value, it can be determined in the confined space. can be judged to be impossible. For example, if the concentration of hydrogen peroxide sprayed into the confined space is equal to or greater than a predetermined reference value, it is possible to block access of workers entering the confined space. According to the control of the control unit 160, it is possible to prevent entry and exit of workers by preventing the door of the confined space from being opened or by preventing the lighting member of the confined space from being turned on. In addition, a detection sensor may detect a worker entering the confined space, and the detection sensor may transmit a detection signal to the control unit 160 . At this time, the control unit 160 can generate a warning sound through a speaker according to the transmitted detection signal so that the operator can recognize a dangerous situation that entering the confined space is dangerous. The warning sound may be generated until the operator is not detected by the detection sensor. That is, it may be generated until the worker leaves the confined space. Therefore, if the concentration value of hydrogen peroxide is higher than the standard value, the worker is prevented from entering the confined space, and only when the concentration value of hydrogen peroxide is less than the standard value, which is the safe level, it is possible to monitor and control whether the worker enters the confined space. Worker safety can be increased.

The monitoring unit 150 may monitor the concentration of hydrogen peroxide measured by the concentration measuring unit 130 . In some embodiments, the monitoring unit 150 may be a laptop or PC. Through the monitoring unit 150, the operator can easily check whether or not he or she is working in a confined space.

The control unit 160 may control the sterilization/sterilization device 110 and each unit.

Also, referring to FIG. 2 , in some embodiments, the control system 100 for remotely monitoring sterilization/sterilization of an enclosed space may further include a sterilization/sterilization state determining unit 170 . The sterilization/sterilization state determination unit 170 may determine the sterilization/sterilization state of the closed space where hydrogen peroxide is sprayed. In some embodiments, the sterilization / sterilization state determination unit 170 determines that the closed space is sterilized / sterilized when the concentration of hydrogen peroxide measured by the concentration measurement unit 130 exceeds a predetermined reference value for a certain period of time. there is.

Also, in some embodiments, the control system 100 for remotely monitoring sterilization/sterilization of an enclosed space may further include a plasma generating unit 180. The plasma generating unit 180 is installed in the solution spraying unit 112 of the sterilization / sterilization device 110 and promotes the diffusion of hydrogen peroxide sprayed into the solution spraying unit 112 to reduce the concentration difference of hydrogen peroxide in the closed space. there is. Therefore, the sterilization / sterilization efficiency of the closed space can be further increased.

In addition, in some embodiments, the control system 100 for remotely monitoring sterilization/sterilization of an enclosed space may further include a wireless remote controller 190. The wireless remote controller 190 can operate the sterilization/sterilization device 110, the lighting member installed in the confined space, the entrance door of the confined space, the spray amount control unit, and various sensors from outside the confined space. The wireless remote controller 190 may include a number and an increase/decrease button for controlling the spray amount of hydrogen peroxide, a button for turning on/off the operation of a sensor and a lighting member, and a button for opening/closing a door. Therefore, the operator can monitor the concentration of hydrogen peroxide inside the closed space with graphs and numerical values from outside the closed space, and also adjust the concentration of the peroxide without entering the closed space.

In addition, referring to FIG. 3, looking at the process of sterilizing / sterilizing by introducing water peroxide into an enclosed space in some embodiments, when it is determined that sterilization / sterilization of an enclosed space is necessary, hydrogen peroxide can be injected into the enclosed space. . Hydrogen peroxide is injected for a certain period of time, the concentration of hydrogen peroxide injected into the closed space is measured in real time by the concentration measurement unit 130, and the measured concentration of hydrogen peroxide can be transmitted to the monitoring unit 150. At this time, the monitoring unit 150 displays the concentration value of hydrogen peroxide as a numerical value or a graph, and the graph displays the amount and concentration of the water peroxide introduced, as well as the time spent in the closed space while maintaining a certain concentration. .

On the other hand, if the concentration of hydrogen peroxide measured by the concentration measuring unit 130 is the set concentration, the injection of hydrogen peroxide may be stopped and the residence time of the hydrogen peroxide remaining in the closed space may be maintained for a predetermined time. In addition, after the retention time of hydrogen peroxide staying in the closed space has elapsed for a predetermined time, the concentration of hydrogen peroxide in this state can be measured by the concentration measurement unit 130 and transmitted to the monitoring unit 150. The monitoring unit 150 not only displays the concentration of hydrogen peroxide measured by the concentration measurement unit 130, but also confirms that the concentration of hydrogen peroxide staying in the closed space decreases because a certain amount of time has elapsed without hydrogen peroxide being introduced. there is. After confirming that the concentration of hydrogen peroxide is lowered in the graph in the monitoring unit 150, the operator can enter and exit the confined space. Therefore, since the time to sterilize/sterilize the closed space by hydrogen peroxide can be predicted, the work waiting time can be reduced and the work efficiency can be increased.
