The operation of the high-pressure steam medical disinfection sterilization apparatus using a low-temperature plasma according to an embodiment of the present invention configured as described above will be described below.

First, the case of disinfection using high-pressure steam according to the type of medical equipment and equipment to be disinfected.

After injecting the medical equipment and equipment to be sterilized into the chamber 11 of the sterilization apparatus 10, the door 12 is closed. Then, the key operation unit 14 starts disinfection operation.

The control unit 50 receiving the operation start command of the key operation unit 14 opens the first sole valve 21, the first ozone decomposer 26, the first vacuum pump 27, and the second ozone. Drive the cracker 28.

The air in the chamber 11 is sucked into the discharge port by the driving of the first vacuum pump 27.

Therefore, the air inside the chamber 11 passes through the first sole valve 21 and passes through the first air filter 22. The impurities are filtered out, and the air contained in the air passes through the first composite filter 24. The bacteria are removed, the dust and water are separated and the separated water is stored in the first water container 25.

The air passing through the first composite filter 24 passes through a first ozone decomposer 26 to decompose ozone gas contained in the air, passes through a first vacuum pump 27, and a second ozone decomposer 28. After decomposing the secondary ozone through the body is discharged to the outside.

Therefore, the inside of the chamber 11 proceeds in a vacuum state while the air is forced to be discharged to the outside. At this time, if the internal pressure of the chamber 11 is detected by the vacuum pressure sensor 17 and the vacuum state is detected, the controller 50 Closes the first sole valve 21 and stops the driving of the first vacuum pump 27 and the first and second ozone generators 26 and 28.

This process is referred to as <initial vacuum mode> below for convenience.

After the chamber 11 is vacuumed as described above, the controller 50 drives the second vacuum pump 35, closes the second solenoid valve 63 of the steam generating and recovery device 60, and vaporizes the steam. The generator 61 is driven.

Accordingly, air is introduced from the outside of the main body through the second air filter 31 by the driving of the second vacuum pump 35, and impurities in the air introduced through the second air filter 31 are filtered. The bacteria contained in the air are removed while passing through the second composite filter 33, and the dust and water are separated and stored in the second water container 34.

Air passing through the second composite filter 33 is introduced into the chamber 11 through the second vacuum pump 35, the first check valve 36, and the second check valve 39.

Therefore, when the <Initial Vacuum Mode> operation is completed,

The controller 50 stops the driving of the first vacuum pump 27, the first and second ozone decomposers 25, 28, and the second vacuum pump 35, the low temperature plasma generator 37, and ozone. The generator 38 is driven.

Accordingly, air is introduced from the outside of the main body through the second air filter 31 by the driving of the second vacuum pump 35, and impurities in the air introduced through the second air filter 31 are filtered. The bacteria contained in the air are removed while passing through the second composite filter 33, and the dust and water are separated and stored in the second water container 34.

Air passing through the second composite filter 33 passes through the second vacuum pump 35 and the first check valve 36 to the low temperature plasma generator 37 and the ozone gas generator 38. ) And the low temperature plasma and ozone gas generated through the low temperature plasma generator 37 and the ozone gas generator 38 are introduced into the chamber 11 through the second check valve 39.

At this time, the chamber 11 is maintained in a vacuum state, so that the low temperature plasma gas and the ozone gas introduced into the chamber can be easily and quickly introduced into every corner of the inside (pipe or pipe structure) as well as the outside of the object to be disinfected. Will be effective.

This process is referred to as <vacuum pressure sterilization mode> for convenience.

In the case of the gas sterilization disinfection using the vacuum pressure, the controller 50 repeats the <vacuum mode> and <vacuum pressure gas sterilization mode> several times (for example, 3-4 times).

Through this process, the medical equipment and equipment that is the object to be sterilized in the chamber 11 are completely sterilized and sterilized.

Third, the case of complex disinfection using high-pressure steam and vacuum gas according to the type of medical equipment and equipment to be disinfected.

The air flows into the chamber 11 through the check valve 39, and the air in the chamber flows from the first sole valve 21 to the first air filter 22 to the first pressure sensor 23 to the first composite filter 24. The first ozone decomposer 26 is discharged to the outside through the first vacuum pump 27 and the second ozone decomposer 28.

At this time, when ozone is not detected in the chamber 11 through the ozone sensor 16, and at the same time the inside of the chamber 11 is in the atmospheric pressure state through the vacuum pressure sensor 17, the driving is stopped and the sterilization and disinfection operation is terminated. .

In addition, after the operation of the <vacuum pressure sterilization mode>, the controller 50 opens the first sole valve 21 and the second sole valve 63, and the first ozone decomposer 26 and the first dust. The pneumatic pump 27, the second ozone decomposer 28, and the second vacuum pump 35 are driven. At this time, driving of the low temperature plasma generator 37 and the ozone generator 38 is stopped.

Therefore, the air introduced from the outside air flows from the second air filter 31 to the second pressure sensor 32 to the second composite filter 33 to the second vacuum pump 35 to the first check valve 36 to the second air filter. The air flows into the chamber 11 through the check valve 39, and the air in the chamber flows from the first sole valve 21 to the first air filter 22 to the first pressure sensor 23 to the first composite filter 24. The first ozone decomposer 26 is discharged to the outside through the first vacuum pump 27 and the second ozone decomposer 28.

At this time, when ozone is not detected in the chamber 11 through the ozone sensor 16 and at the same time the inside of the chamber 11 is in the atmospheric pressure state through the vacuum pressure sensor 17, the driving is stopped and the sterilization and disinfection operation is terminated. .

These processes are referred to as <disinfection complete mode> for convenience.

In the operation of the present invention, the <vacuum pressure gas sterilization mode> and <compound sterilization mode> by selectively operating the oxygen generator 41 to increase the concentration of low-temperature plasma and ozone to double the sterilization effect In the <high pressure steam sterilization mode>, <vacuum pressure gas sterilization mode> and <compound sterilization mode> by selectively operating the hot air generating device 42 by blowing hot air into the chamber 11 to dry It can also be used to perform functions.

At the same time, the first and second ozone decomposers 25 and 28 and the steam generator 61 are stopped, and the first vacuum pump 27, the low temperature plasma generator 37, and the ozone generator 38 are driven. Let's do it.

Therefore, the air introduced from the outside air flows from the second air filter 31 to the second pressure sensor 32 to the second composite filter 33 to the fifth solenoid valve 75 to the first vacuum pump 27 to the sixth. The solenoid valve 76 → the first check valve 36, the low temperature plasma generator 37 and the ozone generator 38 → the second check valve 39 to the chamber 11 together with the plasma and ozone gas generated Is committed.

In the case of <Compound Sterilization Mode>,

The controller 50 closes the third sole valve 73 and the fourth sole valve 74, and opens the fifth sole valve 75 and the sixth sole valve 76.

At the same time, the driving of the first and second ozone decomposers 25 and 28 is stopped, and the first vacuum pump 27, the low temperature plasma generator 37, the ozone generator 38 and the steam generator 61 are driven. Let's do it.

Therefore, the air introduced from the outside air flows from the second air filter 31 to the second pressure sensor 32 to the second composite filter 33 to the fifth solenoid valve 75 to the first vacuum pump 27 to the sixth. The solenoid valve (76) → the first check valve (36) → the low temperature plasma generator (37) and the ozone generator (38) → the second check valve (39) flows into the chamber (11) and at the same time generates steam and The steam generated from the steam generator 61 of the recovery device 60 is introduced into the chamber 11.

On the other hand, in the case of <Disinfection complete mode>,

First, after the operation of the <high pressure steam sterilization mode> and the <compound sterilization mode>, the operation of the steam generator 61 of the steam generation and recovery device 60 is stopped, and the second sole valve 63 is opened. The vapor in the chamber 11 is discharged to the outside.

The controller 50 opens the first sole valve 21 and the third to sixth sole valves 73 to 76, and the first ozone decomposer 26, the first vacuum pump 27, and the second. The ozone decomposer 28 is driven. At this time, driving of the low temperature plasma generator 37 and the ozone generator 38 is stopped.

Therefore, the air introduced from the outside air flows from the second air filter 31 to the second pressure sensor 32 to the second composite filter 33 to the fifth solenoid valve 75 to the first vacuum pump 27 to the sixth. The sole valve (76) → the first check valve (36) → the second check valve (39) flows into the chamber (11), and the air in the chamber is the first sole valve (21) → the first air filter (22). → first pressure sensor (23) → first composite filter (24) → first ozone cracker (26) → first vacuum pump (27) → second ozone cracker (28). The distilled water generated after cooling by being discharged to the cooling device 64 through the second sole valve 63 of the steam generation and recovery device 60 is stored in the distilled water storage tank 62.

At this time, when ozone is not detected in the chamber 11 through the ozone sensor 16 and at the same time the inside of the chamber 11 is in the atmospheric pressure state through the vacuum pressure sensor 17, the driving is stopped and the sterilization and disinfection operation is terminated. .

In addition, after the operation of the <vacuum pressure sterilization mode>, the controller 50 opens the first sole valve 21, the second sole valve 63, and the third to sixth sole valves 73 to 76. The first ozone decomposer 26, the first vacuum pump 27, and the second ozone decomposer 28 are driven. At this time, driving of the low temperature plasma generator 37 and the ozone generator 38 is stopped.

Therefore, the air introduced from the outside air flows from the second air filter 31 to the second pressure sensor 32 to the second composite filter 33 to the fifth solenoid valve 75 to the first vacuum pump 27 to the sixth. The sole valve (76) → the first check valve (36) → the second check valve (39) flows into the chamber (11), and the air in the chamber is the first sole valve (21) → the first air filter (22). ) Is discharged to the outside through the first pressure sensor 23, the first composite filter 24, the first ozone decomposer 26, the first vacuum pump 27, and the second ozone decomposer 28.

At this time, when ozone is not detected in the chamber 11 through the ozone sensor 16 and at the same time the inside of the chamber 11 is in the atmospheric pressure state through the vacuum pressure sensor 17, the driving is stopped and the sterilization and disinfection operation is terminated. .
