Description

Space and medical equipment sterilizer using dual type plasma platform {STERILIZER FOR ROOM AND MEDICAL INSTRUMENTS USING DUAL TYPE PLASMA PLATFORM}

The present invention relates to a sterilizer, and more particularly, after making the disinfectant in an activated state by plasma discharge, by increasing the dissolved amount of active oxygen species contained in the disinfectant through microbubbles, it is possible to maintain a high energy state for a longer time. In addition to expanding the applicability to space disinfection, the sterilization solution can be circulated, vaporized, or RNOS plasmaized in the chamber for disinfection of medical devices, thereby enabling a higher level of disinfection in the case of space disinfection. The present invention relates to a space and medical device sterilizer using a dual-type plasma platform capable of expanding the range of disinfection and disinfection targets using a disinfection solution generated by plasma discharging a disinfectant solution.

In general, many medical devices that are used in an environment exposed to germs and germs and are easily contaminated require a high level of sterilization before reuse. Currently, sterilizers or sterilizers using _{hydrogen peroxide (H 2} O _{2) and plasma} The medical devices used once are cleanly sterilized or sterilized and reused.

As such, a sterilizer or sterilizer using hydrogen peroxide and plasma activates the sterilizing solution through high injection pressure and performs plasma discharge treatment by applying a high voltage of about 17,000 to 20,000 V, thereby converting hydrogen peroxide, a sterilizing solution, into active radicals in a high energy state It sterilizes germs and germs that exist in medical devices.

Accordingly, medical institutions often have plasma sterilizers to sterilize surgical medical instruments. These plasma sterilizers place medical instruments in a separate chamber and then supply a sterilizing solution such as plasma-treated hydrogen peroxide into the chamber. It completely removes germs and bacteria remaining in various medical devices.

In addition, in recent years, as we have experienced a strong infectious power of variously mutated influenza viruses and respiratory diseases such as MERS, the importance of sterilization of spaces where patients, medical personnel or visitors move or stay beyond simply medical equipment used for surgery has also increased. It's going up significantly.

Therefore, if the high sterilization power can be used for disinfection of the space or passage in the hospital where patients, medical personnel or visitors move or stay, the likelihood of infection of several people using the space or passage in the hospital can be greatly reduced. There was a problem that it was not easy to disinfect the various spaces in the hospital where people stay or move.

In addition, if a disinfection facility is to be installed in all spaces in the hospital, there is a problem that it is difficult to easily attempt because the cost for installation and maintenance is greatly increased, and it is desirable to use a plasma device to realize excellent sterilization and disinfection effects. However, if such a plasma device can be used for sterilizing germs or bacteria in a large space outside a small chamber, there is a problem in that the cost for implementing the plasma device is unbearably increased.

Accordingly, although the need for sterilization devices for sterilizing spaces in hospitals such as hospital rooms and corridors is increasing, there is no adequate means for sterilizing or disinfecting the entire space, and even in the case of space sterilization devices currently being tried. It has been difficult to find a sterilization or sterilization device that provides a strong sterilization power, as if using plasma, beyond the level of simple air purification.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

1 is a block diagram of a space and instrument sterilizer using a dual-type plasma platform according to the present invention, and FIG. 2 is an exemplary configuration diagram of a space and instrument sterilizer using a dual-type plasma platform according to the present invention.

Referring to FIG. 1, a space and instrument sterilizer using a dual-type plasma platform according to the present invention includes a disinfectant tank 100 in which a hydrogen peroxide-based disinfectant for disinfection of a space or apparatus is stored, and a high voltage is applied from the outside. By discharging the supplied gas to plasma to generate reactive oxygen species (ROS), the hydrogen peroxide-based disinfectant supplied from the disinfectant tank is activated by the high energy of the reactive oxygen species, and the activated disinfectant is microbubbled to activate it. A dual-type plasma platform 200 that generates a high-energy sterilization solution with enhanced sterilization power by increasing the dissolved amount of oxygen species, and a solution tank 300 that temporarily stores the sterilization solution generated from the dual-type plasma platform. , And a connection mount 400 for selectively supplying and ejecting the sterilization solution stored in the solution tank to two discharge paths for space sterilization or device sterilization.

The disinfectant tank 100 is a storage space in which a disinfectant solution having sterilization and disinfection ability is stored, and in the above embodiment, it is exemplified that it is composed of a disinfectant based on _{hydrogen peroxide (H 2} O _{2 ), but the disinfectant solution is not limited thereto.} It goes without saying that it can be of various types depending on the main object to be sterilized and disinfected. Accordingly, in the above embodiment, a low concentration hydrogen peroxide disinfection solution (containing 6% or less hydrogen peroxide) containing a small amount of hydrogen peroxide in water is stored in the disinfectant tank 100. Of course it may be. In addition, it goes without saying that the disinfectant solution may further contain an additive capable of enhancing the activation of hydrogen peroxide.

In this case, as shown in FIG. 2, a neutralization unit 110 for supplying a diluent or distilled water as a neutralizing agent capable of lowering the concentration of the disinfectant solution in order to neutralize the disinfectant solution stored in the disinfectant tank to a level suitable for space disinfection. It may be configured to further include.

In addition, as shown in FIG. 2, it may be configured to further include an additive supply unit 120 capable of mixing by adding various additives for improving the disinfecting power and sterilizing power of the disinfectant solution stored in the disinfectant tank.

At this time, as an additive for improving the disinfecting power and sterilizing power of the disinfectant, antibacterial agents such as Phytpncide, Tea tree leaf Oil, and Eucalyptus Oil may be used, and such antibacterial agents may be used as a disinfectant. By adding to it, not only can the disinfecting power and sterilizing power be improved, but also the sour odor peculiar to hydrogen peroxide can be canceled to remove unpleasant odors that may be caused during space disinfection.

In addition, the chamber further comprises a concentrating unit 130 for concentrating the disinfectant solution supplied from the disinfectant tank and converting it into plasma by the active oxygen species generated in the dual-type plasma platform so as to disinfect the medical device at a high level. It can also be configured. Therefore, since the concentration of the disinfectant to be converted into a plasma state can be adjusted by controlling whether the heater constituting the concentrator is operated, a low-concentration disinfectant is used while using a high-concentration disinfectant according to the disinfection level of the medical device to be disinfected in the chamber. It is possible to realize the same disinfection efficiency.

In addition, the dual-type plasma platform 200 provides a high-energy state capable of activating the disinfectant solution, but maintains a high-energy state for a longer period of time not only disinfecting inside the chamber but also disinfecting spaces such as hospital rooms or corridors. By doing so, it is configured to increase the dissolved amount of active oxygen species (ROS) in order to be able to improve the sterilization and disinfection ability.

To this end, the dual-type plasma platform 200 generates a high-energy reactive oxygen species (ROS) by applying a high voltage to plasma discharge to activate the hydrogen peroxide-based disinfectant supplied from the disinfectant tank ( 210) and a microbubble generator 220 for increasing the dissolved amount of the reactive oxygen species by microbubbles the disinfectant liquid activated by the high energy of the reactive oxygen species generated by plasma discharge. At this time, the plasma generator 210 applies a high voltage of about 1 to 2 kV to enable plasma discharge, and generates an active oxygen species (ROS) having a high energy of 1 to 20 W by such plasma discharge. It is structured to be able to.

In general, plasma in a high energy state is unstable, so it quickly returns to a stable state while releasing energy. Accordingly, in order to disinfect a large space out of a narrow chamber, it is necessary to maintain an unstable high energy state for a long time. If the dissolved amount of the active oxygen species in the high energy state contained in the disinfectant activated by is increased, the plasma state can be maintained for a longer time, and thus the disinfectant solution can be maintained in the activated state for a longer time.

Accordingly, in the dual-type plasma platform 200, a hydrogen peroxide-based disinfectant is exposed to the active oxygen species discharged by plasma to activate it in a high energy state, and then the activated disinfectant is microbubbled to form the active oxygen species contained in the disinfectant. By creating a sterilization solution with an increased amount of dissolved in, the high energy state can be maintained for a longer period of time, so that it can be applied to space sterilization.

In addition, as shown in FIG. 2, the dual-type plasma platform 200 is supplied with a predetermined amount of a disinfectant solution to be activated in contact with the active oxygen species in a high energy state generated by the plasma generating unit 210 at a strong pressure. It may be configured to further include a liquid pump 230 to control it. At this time, the disinfectant supplied by the liquid pump 230 may be a disinfectant stored in the disinfectant tank, as well as a disinfectant to which a neutralizing agent such as distilled water is added, or a disinfectant to which an additive is added.

In this way, by supplying the disinfectant solution at a strong pressure by the liquid pump 230, a sterilization solution, which is a plasma disinfectant that is supplied to a mist nozzle for space disinfection together with active oxygen species in a high energy state, can be supplied more quickly and further away. Therefore, it is possible to maintain the high energy state of the sterilization solution until it reaches the space to be sterilized.

In addition, of course, the dual-type plasma platform 200 should further include an air compression unit 240 that sucks and compresses external air and supplies it to an electrode constituting the plasma generating unit.

In addition, the solution tank 300 is configured as a storage tank temporarily storing a sterilization solution containing a large amount of active oxygen species in a high energy state while passing through the dual-type plasma platform 200, and such a solution tank The sterilization solution stored in 300 is configured to be discharged for disinfecting the space or disinfecting medical devices in the chamber through the connection mount 400 that is selectively opened according to the object to be disinfected.

At this time, the connection mount 400 is to provide a path through which the high-energy sterilization solution stored in the solution tank 300 is discharged for disinfection. The sterilization solution can be supplied for disinfecting the space, and it can be used in two ways depending on the object to be sterilized, such as being supplied for disinfection of medical devices stored in the chamber.

To this end, the connection mount 400 includes a nozzle connection part 410 to which the mist nozzle 500 is coupled so that a sterilization solution can be sprayed into a space such as a hospital room or a corridor for space disinfection, and the disinfection of medical devices. In order to supply a sterilization solution into a specific chamber in which medical instruments such as surgical instruments are placed, all of the chamber connecting portions 420 are configured to be connected to the chambers 600,700,800. In FIG. 2, the mist nozzle 500 for spraying the sterilization solution supplied from the dual-type plasma platform 200 into a space to be sterilized for space disinfection is indicated as a disinfection gun.

At this time, the sterilization solution sprayed into the space by the mist nozzle 500 for disinfection of spaces such as hospital rooms or corridors is in a stable state while rapidly losing energy after being sprayed from the mist nozzle due to the nature of the plasma state with a short duration of unstable state. It returns, but by extending the connection line of the mist nozzle 500 connected to the nozzle connection part 410, the sterilization solution is sprayed, or the sterilizer according to the present invention is moved in the hospital room or corridor to spray the sterilization solution. By making it possible to disinfect a wider area.

In other words, when the plasma-treated sterilization solution is applied to space sterilization, the disinfection ability may be lowered than that of medical devices that are sterilized while stored in the chamber, but sterilization by increasing the dissolved amount of reactive oxygen species by microbubbles. After creating the solution, by strongly spraying it into the space with a strong pressure through the mist nozzle 500, the sterilization solution in the plasma state can be sterilized in a wider space, thus providing a far superior disinfection effect compared to conventional space disinfection. Can be implemented.

In this way, the discharging path of the sterilization solution coupled to the connection mount is connected to the mist nozzle 500 to face a space such as a hospital room or a corridor, or to the chamber 600, 700, 800 to face the chamber in which medical instruments are accommodated. By selectively changing the discharge path, the sterilization solution in the plasma state generated through the same process can be used not only for sterilizing medical devices, but also for sterilizing spaces, thereby expanding the scope of use.

In addition, the disinfectant tank, the dual-type plasma platform, the solution tank, and the connection mount are implemented as a single module or device, and by making these modules or devices movable, they are used for disinfection of medical devices in a specific disinfection room. Of course, it is possible to improve the convenience of moving to the hospital room or corridor to be sterilized beyond that.

At this time, in order to allow the sterilization solution stored in the solution tank to be discharged to a space such as a hospital room or a corridor to sterilize and sterilize bacteria or germs existing in the space, as shown in FIGS. 3 to 5, It is preferable to include a mist nozzle 500 coupled to the nozzle connection part 410 so that the high energy sterilization solution temporarily stored in the solution tank 300 can be ejected with strong pressure.

To this end, in the above embodiment, it is illustrated that a mist nozzle (0.05 lpm, 15 to 33 um) spraying a sterilizing solution of 0.05 liters per minute in a spray form having a size of 15 to 33 um is employed, but the amount of the sterilizing solution ejected per minute or It goes without saying that the size or spraying speed of the mist can be freely changed according to the characteristics of the space to be sterilized.

In addition, by increasing the length of the connection line of the mist nozzle coupled to the nozzle connection portion, it is of course possible to expand the position at which the sterilization solution is sprayed through the mist nozzle.

In addition, in order to use the sterilization solution stored in the solution tank for disinfection of medical devices stored in the chamber, as shown in FIGS. 3 to 5, the high energy state temporarily stored in the solution tank It is preferred that additional devices are further provided which are coupled to the chamber connection so that the sterilization solution can be supplied to the chamber.

In other words, the high-energy sterilization solution that is temporarily stored in the solution tank itself has excellent sterilization and disinfection capabilities, but medical instruments such as surgical tools directly used for human surgery require a higher level of sterilization and disinfection. It is preferable that additional devices are further provided as shown in FIGS. 3 to 5 in consideration of the characteristics of disinfection in the chamber, which is an enclosed space.

As described above, in the case of the additional devices shown in FIGS. 3 to 5, they may be installed in the same housing while forming one device, such as the above-described disinfectant tank, dual-type plasma platform, solution tank, and connection mount. It is preferable that the medical device is provided in a chamber in which the medical device is accommodated so as to improve convenience during movement.

Hereinafter, various embodiments of the components coupled to the chamber connection part of the connection mount for disinfecting medical devices will be described with reference to FIGS. 3 to 5. At this time, in FIGS. 3 to 5, the blue arrows indicate the flow of the disinfectant solution and the sterilization solution for space disinfection, and the red arrow indicates the flow of the disinfectant solution and the sterilization solution for disinfection of medical devices in the chamber.

First, in the first embodiment with reference to FIG. 3, a chamber 600 in which medical instruments to be sterilized are stored in a state blocked from the outside, and a high-energy sterilization solution temporarily stored in the solution tank are misted. A showerhead 610 coupled to the chamber connection to be sprayed into the chamber in a vaporized state in a form, and a vaporized sterilization solution used for disinfecting medical devices inside the chamber after being sprayed through the showerhead And a circulation induction fan 620 for circulating and supplying it back to the solution tank by suction, and a filter 630 for filtering and discharging hydrogen peroxide gas that has lost energy while disinfecting medical instruments in the chamber.

At this time, the chamber 600 must be able to maintain a sealed state so as to prevent leakage of the vaporized sterilization solution during disinfection of the medical device, and a door through which medical instruments to be sterilized can be inserted and removed Of course, it must be provided.

In addition, the shower head 610 supplies a high-energy sterilization solution temporarily stored in the solution tank 300 into the chamber in a vaporized state, and the circulation induction fan 620 is present in the chamber. This is to realize a circulation path of the sterilization solution by inhaling the sterilizing solution in the vaporized state back into the solution tank 300.

The high-energy sterilization solution supplied from the showerhead to the chamber loses energy in the process of disinfecting germs or germs in the medical device, and the sterilization and sterilization ability rapidly decreases, but is sucked into the solution tank by the circulation induction fan. After receiving energy from other high-energy sterilization solutions, it is circulated to the chamber through the showerhead to restore the deteriorated sterilization and disinfection capabilities to a certain level, thereby improving the efficiency of disinfecting medical devices in the chamber. You will be able to do it.

Accordingly, the sterilization and disinfection efficiency can be improved compared to the sterilization and disinfection efficiency of conventional medical devices that only waited for the discharge through filtration through the filter after the sterilization and disinfection capability is lost once without circulation of this sterilization solution, as well as the consumption of the disinfectant solution. Can be reduced.

At this time, the shower head 610 is for spraying the high-energy sterilization solution supplied from the solution tank into the chamber 600 in a vaporized state, and is placed inside the chamber where the object for disinfection is limited. As there is, it is preferable that it is configured to be sprayed at a weaker pressure than the mist nozzle spraying the sterilizing solution for disinfecting the space. Accordingly, in the above embodiment, the showerhead was configured by adopting a nozzle (0.02lpm, 8.6um) that sprays a sterilization solution of 0.02 liters per minute in a spray form having a size of 8.6 um, but is not limited thereto and is intended to be sterilized. It is of course possible to freely change the amount of the sterilization solution sprayed, the size of the mist, or the spraying speed according to the type of medical device or the size of the chamber.

In addition, although the circulation induction fan 620 is set to be driven at a speed capable of inhaling a sterilization solution of about 118 liters per minute (118 lpm), the inhalation rate and amount of inhalation are also the type and disinfection of medical devices to be sterilized. Of course, it can be freely changed according to the level.

Next, in the second embodiment with reference to FIG. 4, a chamber 700 in which medical instruments to be sterilized are stored in a state blocked from the outside, and a high-energy sterilization solution temporarily stored in the solution tank are fine particles. A vaporization unit 710 that is vaporized to a size and then supplied into the chamber, and a filter 730 that filters and discharges hydrogen peroxide gas that has lost energy while disinfecting medical instruments in the chamber.

At this time, the chamber 700 must be able to maintain a sealed state to prevent leakage of the vaporized sterilization solution during disinfection of medical devices, and a door through which medical instruments to be sterilized can be put into and out of the chamber is provided. Of course, it must be provided.

In addition, the vaporization unit 710 is coupled to the chamber connection unit 420 to supply the sterilization solution temporarily stored in the solution tank into the chamber in a vaporized state, and a high energy state supplied from the solution tank The sterilization solution of is vaporized to a particle size having a size of about 1 μm or less by ultrasonic waves, and then supplied into the chamber.

In this way, the sterilization solution in high energy state can be further activated by evaporating it to the particle size by ultrasonic waves, so that the sterilization solution in the particle size can spread to all parts of the medical equipment stored in the chamber, allowing the medical tools to be sterilized at a high level. do.

Next, in the third embodiment with reference to FIG. 5, a chamber 800 in which medical instruments to be sterilized are stored in a state blocked from the outside and a high-energy sterilization solution temporarily stored in the solution tank are vaporized. A vaporizer 810 that makes the vaporizer 810, an RNOS plasma generator 820 that converts the sterilizing liquid vaporized from the vaporizer into RNOS plasma by a microwave torch and supplies it into the chamber, and a medical device inside the chamber. It is configured to include a filter 830 for filtering and discharging hydrogen peroxide gas, which is a sterilizing liquid that has lost energy while disinfecting.

At this time, the chamber 800 must be able to maintain a sealed state so as to prevent leakage of the vaporized sterilization solution during disinfection of the medical device, and a door through which medical instruments to be sterilized can be inserted and removed Of course, it must be provided.

The vaporizer 810 is a device that vaporizes by heat exchange, and is configured to vaporize a high-energy sterilization solution supplied from the solution tank 300 and transmit it to the RNOS plasma generator 820.

The RNOS plasma generator 820 converts the sterilization solution supplied after vaporization from the vaporizer 810 into RNOS (Reactive Nitrogen Oxide Species) plasma using a microwave torch, thereby improving sterilization and disinfection capabilities. It is configured to convert it into an energy state.

As described above, the sterilization solution converted to a high-energy state while being converted to plasma by the RNOS plasma generator 820 is introduced into the interior space of the chamber and rapidly sterilizes and disinfects medical instruments stored therein to a high level.

In this way, the sterilization solution supplied to the chamber enables a higher level of sterilization and sterilization in the chamber by circulating, vaporizing, or converting the sterilization solution of high energy stored in the solution tank into RNOS plasma. In addition, the sterilization solution used for sterilization of spaces such as hospital rooms or corridors increases the amount of ROS dissolved by microbubbles to increase the maintenance time of the unstable high energy state. And can be used selectively for disinfection of spaces. Accordingly, it is possible to increase the utilization of the plasma sterilizer, which can only be used to sterilize medical devices in the chamber, and thereby reduce the maintenance cost of the sterilizer.
