Description

Sterilizer and sterilization method using the same {sterilizer and sterilization method using the same}

The present invention relates to a sterilization apparatus and a sterilization method using the same, and more particularly, to a sterilization apparatus and a sterilization method provided with an internal circulation line for circulating the interior of the fluid flow into the large volume chamber.

Sterilization means the complete removal of all living microorganisms, apart from washing or disinfection. Sterilization is achieved through physical or chemical action.

Sterilization is used in various fields and plays an important role, especially in the field of medical devices. Currently, sterilization of medical devices uses ethylene oxide (EO) gas, steam, hydrogen peroxide, and plasma.

Ethylene oxide gas has the advantage that it can kill all kinds of microorganisms, does not require high temperature, high humidity and high pressure, and does not damage instruments or articles. However, ethylene oxide gas has been defined as a carcinogen, and there is a concern that ethylene oxide gas may remain in the sterilization object due to difficult management and relatively long sterilization time.

In addition, the steam sterilization method is a method of sterilizing at a high temperature of 100 ℃ or more by filling the sealed container with saturated steam and pressurized, it is possible to sterilize all microorganisms. However, since the steam sterilizer method needs to be exposed to high temperature and humidity, there is a problem that only sterilization objects which do not cause deformation even in high temperature and humidity can be sterilized.

Other sterilization methods and related devices are known devices and methods using hydrogen peroxide, Korean Patent Publication No. 10-1784719 ("Sterilization Method and Apparatus Using the Same", 2017.09.28.).

Since hydrogen peroxide has high sterilization power and is discharged by being decomposed into water vapor and oxygen when discharged to the outside, it is an eco-friendly sterilization material and sterilization process is performed at 60 ° C. or lower, so that even heat-sensitive sterilization objects can be sterilized. .

However, this has a limitation in the chamber capacity because a gaseous sterilant (hydrogen peroxide) has to be introduced into the chamber in a vacuum state and then diffused to penetrate the sterilization object. Generally, the capacity of the chamber used is a problem that the sterilization process takes a long time because it can not accommodate a large amount of the sterilization target of about 20L.

First, the first preheating step (S100) is a step of raising the temperature inside the sterilization space 110 and lowering the humidity, and the outside air is injected from the outside air injection unit 210 and the injected outside air is the dehumidifier 220. And moisture and impurities included in the outside air through the filter 230.

The external air from which moisture and impurities are removed moves to the vaporization part 240 and moves to the fluid supply space 120 through the inlet line 250 connected to the vaporization part 240.

In this case, the fluid supply space 120 is further provided with a heater 150 for temperature control of the sterilization space 110, the outside moved to the fluid supply space 120 through the inlet line 250 Air is heated by the heater 150, and is moved to the edge of the fluid supply space 120 by the fan 121 and the internal circulation line 111 → the sterilization space 110 → the partition wall hole. (131) → the fluid supply space 120 → the internal circulation line 111 is repeated and circulated in order to allow the sterilization space 110 to be suitable temperature and humidity for the sterilization process.

At this time, the temperature of the sterilization space 110 is about 60 ℃, the humidity is preferably 30% or less.

In other words, the sterilization space 110 is a fluid supplied from the fluid supply unit 200 is moved to the edge of the fluid supply space 120 and the inner circulation line 111 → the sterilization space 110 → the Partition wall 131 → the fluid supply space 120 → the inner circulation line 111 in the order, the circulating fluid is repeatedly heated by the heater 150, so preheating the sterilization space 110 Done.

In addition, dry air should be injected into the sterilization space 110 in order to lower the humidity in the sterilization space 110. To this end, outside air is introduced from the outside air inlet unit 210, and moisture and impurities are removed through the dehumidifier 220 and the filter 230, and the outside air formed of dry air is the vaporization unit 240 and the inflow. It moves to the fluid supply space 120 through the line 250, and moves to the edge of the fluid supply space 120 by the fan 121 and the inner circulation line 111 → the sterilization space 110. ) To lower the humidity in the sterilization space (110).

When the humidity in the sterilization space 110 is 30% or less, it is preferable to proceed only the process of raising the temperature in the sterilization space 110 without a separate external air injection from the external air injection unit 210, Since the temperature of the fluid that raised the temperature of the sterilization space 110 is not lowered by the external air injected from 210, the sterilization space 110 may be preheated quickly.

After the first preheating step S100, the first sterilization step S110 is performed. The sterilant in the liquid state contained in the sterilant accommodating part 241 moves to the vaporization part 240 to be in a gaseous state, and is mixed with external air passing through the dehumidifier 220 and the filter 230 to the It moves to the fluid supply space 120 through the inlet line 250 connected to the vaporizer 240.

The mixed air (the sterilant in the external air + gas state) moved to the fluid supply space 120 through the inlet line 250 is heated by the heater 150, and by the fan 121 It moves to the edge of the fluid supply space 120, moves along the inner circulation line 111, is discharged through the circulation hole 112, and is supplied to the sterilization space 110.

In this case, the first sterilization step (S110) is characterized in that the mixed air is continuously introduced and continuously discharged, the mixed air supplied to the sterilization space 110 is in contact with the sterilization target the fluid The mixed air moves to the supply space 120 and is discharged through the exhaust line 260 provided in the fluid supply space 120.

The exhaust line 260 is provided with the catalyst 270 that decomposes a gaseous sterilant into water and oxygen, and the mixed air passing through the catalyst 270 is transferred to the outside through the blower 280. Discharged.

After the first sterilization step S110, the first ventilation step S120 for removing the sterilant and water remaining in the sterilization space 110 is performed. In the first ventilation step (S120), outside air is injected from the outside air injection unit 210, and the injected outside air passes through the dehumidifier 220 and the filter 230 to store moisture and impurities contained in the outside air. Removed.

The external air from which moisture and impurities are removed moves to the vaporization part 240 and moves to the fluid supply space 120 through the inlet line 250 connected to the vaporization part 240.

The external air supplied to the fluid supply space 120 is heated by the heater 150, moves to the edge of the fluid supply space 120 by the fan 121, and the internal circulation line 111. Moving along the discharge through the circulation hole 112 is supplied to the sterilization space (110).

Like the first sterilization step (S110), the first ventilation step (S120) is also continuously discharged at the same time as gas is continuously introduced, and the external air supplied to the sterilization space (110) is supplied to the fluid supply space (120). And the mixed air is discharged through the exhaust line 260 installed in the fluid supply space 120.

The exhaust line 260 is provided with the catalyst 270 for decomposing sterilant into water and oxygen, and the sterilant and external air remaining in the sterilization space 110 pass through the catalyst 270. After passing through the blower 280 is discharged to the outside through the outlet 290.

In the sterilization process, the humidity control of the sterilization space 110 is most important. When the humidity in the sterilization space 110 is increased by more than 35%, the sterilant in a gaseous state begins to condense with water, thereby reducing sterilization power.

Therefore, the humidity of the sterilization space 110 should not be increased, but when the sterilization process proceeds to the first embodiment described above, the first sterilization step (S110) is interrupted while the first ventilation step (S120) is performed. After that, the first sterilization step (S110) needs to be performed again, so there is a problem in that the sterilization process takes a long time.

Therefore, it will be described a sterilization method that can simultaneously control the humidity of the sterilization space 110 during the sterilization step through the sterilization method of another embodiment of the present invention.

Figure 7 shows a sterilization method flow chart using a sterilization apparatus according to a second embodiment of the present invention. Sterilization method according to a second embodiment of the present invention proceeds to the second preheating step (S200), the second sterilization step (S210) and the second ventilation step (S230) and, if necessary, the dehumidifying agent installed in the dehumidifier 220 The dehumidifying agent regeneration step S400 may be further performed.

In addition, when the second sterilization step (S210) proceeds, the temperature and humidity of the sterilization space 110 can be adjusted.

The second preheating step S200 and the second ventilation step S220 are omitted because they proceed in the same manner as the first preheating step S100 and the first ventilation step S120 of the first embodiment of the present invention. , To describe the second sterilization step (S210).

As described above, the second sterilization step (S210) is a sterilant in a liquid state contained in the sterilant accommodating part 241 as described above, and moves to the vaporization part 240 to become a gaseous state, and the dehumidifier 220 and the It is mixed with the outside air passing through the filter 230 and moves to the fluid supply space 120 through the inlet line 250 connected to the vaporization unit 240.

The mixed air moved to the fluid supply space 120 through the inlet line 250 is heated by the heater 150, and is moved to the edge of the fluid supply space 120 by the fan 121. It moves and moves along the inner circulation line 111 to be discharged through the circulation hole 112 is supplied to the sterilization space (110).

At this time, in the first embodiment, the mixed air of the sterilization space 110 is continuously discharged through the exhaust line 260, but in the second embodiment of the present invention, the mixed air is the sterilization space 110 in the The air moved to the fluid supply space 120, and the air moved to the fluid supply space 120 moves through the exhaust line 260.

The mixed air moved to the fluid supply unit 200 through the exhaust line 260 is decomposed into water and oxygen through the catalyst 270, and the water is removed through the blower 280. The air passing through the blower 280 does not discharge to the outside through the outlet 290 and passes through the dehumidifier 220 and the filter 230 to move back to the vaporization unit 240.

At this time, the vaporization unit 240 receives the sterilizing agent from the sterilant receiving unit 241 to move the mixed air to the fluid supply space 120 again.

Therefore, the sterilization method according to the second embodiment of the present invention moves the mixed air moved to the exhaust line 260 to the dehumidifier 220 without directly discharging the mixed air through the outlet 290 so that the fluid supply unit ( Since 200 is continuously circulated, dry air and a sterilant in a gaseous state may be continuously supplied to the sterilization space 110 without supplying external air, thereby maintaining proper humidity in the sterilization space 110. There is an effect that the sterilization process of the sterilization target can also continue.

At this time, the fluid supply unit 200 according to the second embodiment of the present invention is provided with at least one direction switching valve for guiding the movement of the outside air or mixed air, the air passing through the blower 280 is the outlet ( 290 may be discharged or moved back to the dehumidifier 220.

9 is a flowchart illustrating a sterilization method using a sterilization apparatus according to a third embodiment of the present invention. A flowchart of the sterilization method using the sterilization device according to the third embodiment is shown. Sterilization method according to a third embodiment of the present invention proceeds to the third preheating step (S300), the third sterilization step (S310) and the third ventilation step (S320) and, if necessary, the dehumidifying agent installed in the dehumidifier 220 The dehumidifying agent regeneration step S400 may be further performed.

In addition, when the third sterilization step (S310) proceeds, the temperature and humidity of the sterilization space 110 can be adjusted.

The third preheating step S300 and the third ventilation step S320 are omitted because they proceed in the same manner as the first preheating step S100 and the first ventilation step S120 of the first embodiment of the present invention. , To describe the third sterilization step (S310).

The third sterilization step (S310) is a sterilant in a liquid state contained in the sterilant receiving unit 241 as described above is moved to the vaporization unit 240 is a gas state, the dehumidifier 220 and the It is mixed with the outside air passing through the filter 230 and moves to the fluid supply space 120 through the inlet line 250 connected to the vaporization unit 240.
