The present invention relates to a high-pressure steam sterilizer, and more particularly, can automatically and quickly sterilize various types of sterilized objects requiring sterilization work in a vacuum state, and in particular, sterilization work is performed while maintaining a vacuum state. The present invention relates to a high-pressure steam sterilizer capable of quickly discharging air to return to a high vacuum state when air for drying is injected into a sterilization chamber and changes from a vacuum state to an atmospheric pressure state.

In general, various medical instruments must be stored and used after undergoing aseptic treatment, and for this purpose, a method of sterilizing using chemicals or high-temperature steam has been disclosed. In the case of medical devices that are not used directly on the human body, sterilization can be performed using chemicals, but most of the medical devices used on the human body are sterilized using high-temperature and high-pressure steam.

A typical medical high-pressure steam sterilizer is a device that performs aseptic treatment by sterilizing and disinfecting various medical devices and clothing such as surgical gowns and gowns for surgery performed in hospitals or patient treatment with high-pressure steam. It is used for sterilization.

Conventional medical high-pressure steam sterilizers include a chamber forming a sterilization chamber inside for putting various medical devices and clothing such as surgical clothes and gowns (hereinafter referred to as sterilized items), a heater disposed inside the chamber, and supplied to the inside of the chamber It consists of a water storage tank for storing distilled water for processing, a vacuum pump for lowering the atmospheric pressure and wet steam in the chamber, and a solenoid valve for blocking and supplying distilled water and steam to the chamber.

The conventional medical high-pressure steam sterilizer configured as described above sterilizes the sterilized object by inserting the sterilized substance into the sterilization chamber of the chamber, supplying the distilled water stored in the water tank to the sterilization chamber, and then operating the heater to generate high-temperature and high-pressure steam.

In addition, the conventional medical high-pressure steam sterilizer repeats the process of supplying air to the chamber at predetermined time intervals to dry the sterilized product, sucking in and discharging air or moisture present in the sterilization chamber with a pump.

The heater may be disposed in the form of a coil on the inner wall surface of the chamber 10, and when power is applied, it operates by heating to raise the temperature of the sterilization chamber and the sterilization object.

On the other hand, the steam supply unit 20 is configured to supply high-temperature steam for sterilizing the sterilization material to the sterilization chamber.

The steam supply unit 20 is connected to the sterilization chamber through a first connection line 21.

The steam supply unit 20 heats water in a tank (not shown) for storing sterilization materials and supplies high-temperature steam to the sterilization chamber through the first connection line 21 .

The tank is connected to the tap to receive the sterilization material.

The steam supplied to the sterilization room disinfects and sterilizes the sterilized objects while being circulated in the sterilization room.

A first control valve 21a is installed in the first connection line 21 . The first control valve 21a selectively opens or closes the inside of the first connection line 21 and may be formed as a known solenoid valve.

On the other hand, the vacuum unit 30 is a configuration for forcibly discharging air in the sterilization chamber to form a vacuum pressure, and may be formed of a known vacuum pump.

The vacuum unit 30 is connected to the sterilization chamber through the second connection line 31 and forcibly discharges the air present in the sterilization chamber to make the sterilization chamber a set vacuum pressure.

At this time, in the sterilization chamber, atmospheric pressure and wet steam are reduced by the vacuum unit 30 to form a vacuum pressure.

A second control valve 31a is installed in the second connection line 31 . The second control valve 31a selectively opens or closes the inside of the second connection line 31 and may be formed as a known solenoid valve.

On the other hand, the air injection unit 50, the ejector 60, and the drying unit 70 are configured to improve the degree of vacuum of the sterilization chamber together with the oilless pump described later.

The air injection unit 50 includes a fourth connection line 51 connected to the sterilization chamber and an air injector connected to the fourth connection line 51 .

A fourth control valve 51a is installed in the fourth connection line 51 . The fourth control valve 51a selectively opens or closes the inside of the fourth connection line 51 and may be formed as a known solenoid valve.

The air injector is formed as an air pump, and supplies air to the sterilization chamber through the fourth connection line (51).

The ejector 60 is configured to quickly discharge steam, air, and moisture present in the sterilization chamber when the drying unit 70 described below is operated while providing vacuum pressure to the sterilization chamber.

The ejector 60 is connected to the sterilization chamber through the fifth connection line 61 so that the air present in the sterilization chamber is discharged at a high speed, thereby forming a high vacuum.

A fifth control valve 61a is installed in the fifth connection line 61 . The fifth control valve 61a selectively opens or closes the inside of the fifth connection line 61 and may be formed as a known solenoid valve.

On the other hand, the drying unit 70 is a component that generates a suction force required to discharge the moisture present in the sterilization chamber.

For example, the drying unit 70 may be formed as a water pump.

The drying unit 70 is connected to the ejector 60 through a sixth connection line 71 .

Accordingly, the drying unit 70 is also connected to the sterilization chamber via the ejector 60 and the fifth connection line 61.

The drying unit 70 is connected to a separately prepared water storage tank (not shown) through a seventh connection line 3.

A discharge line 2 for discharging the water pumped by the drying unit 70 is connected to the ejector 60 .

The discharge line 2 may be connected to a water storage tank to reuse the water pumped by the drying unit 70 .

The drying unit 70 sucks in and discharges water at high pressure through a pumping operation, and the discharged water may pass through the ejector 60 and the discharge line 2 sequentially and be returned to the water storage tank.

And, while the drying unit 70 is operating, steam, air, and moisture present in the sterilization chamber are discharged through the fifth connection line 61 to dry the sterilized product, and the operation of the drying unit 70 When the water is sequentially discharged through the sixth connection line 71, the ejector 60, and the discharge line 2, the pressure is lowered in the ejector 60 section to suck in steam, air, and moisture. Accordingly, steam, air, and moisture can pass through the fifth connection line 61, the ejector 60, and the discharge line 2 at high speed to be discharged. In this process, maximum vacuum can be generated in the sterilization chamber.

On the other hand, the conversion unit 40 is a configuration that converts the sterilization chamber of the atmospheric pressure state into a vacuum state by discharging the air of the sterilization chamber.

To this end, the conversion unit 40 includes a third connection line 41 connected to the sterilization chamber and an oilless pump connected to the third connection line 41 .

The sterilization chamber maintains a vacuum state by the vacuum unit 30, but when steam is supplied to the sterilization chamber by the steam supply unit 20, the sterilization chamber is converted to atmospheric pressure.

When the sterilization chamber is converted to an atmospheric pressure state, even if the vacuum unit 30 is operated, the degree of vacuum is significantly weakened, so the sterilization efficiency of the sterilized object is reduced.

Therefore, the oil-less pump forcibly discharges the air present in the sterilization chamber through an intake operation, converting the sterilization chamber into a stable vacuum state, thereby preventing the sterilization efficiency of the sterilization material from being lowered.

At this time, since the oilless pump is resistant to moisture, it has the advantage that it does not malfunction due to moisture contained when discharging the air present in the sterilization chamber while converting the sterilization chamber into a vacuum state.

Next, the operation of the high-pressure steam sterilizer 1 described above and the unique effects appearing in the process will be described.

First, the temperature of the sterilization chamber is increased by heating the sterilization chamber with steam generated by opening the first control valve 21a and operating the steam supplier.

At this time, the sterilization chamber is programmed to operate together with the steam supplier, and a heater may be installed to further increase the temperature of the sterilization chamber.

Subsequently, the sterilization chamber is set to a vacuum state by the vacuum unit 30, and after maintaining a predetermined time, air is injected through the air injection unit 50 to set the sterilization chamber to a non-vacuum state.

In the process of repeating the operation of the sterilization chamber in a vacuum state and a non-vacuum state several times, the sterilization chamber is maintained at a high temperature and high pressure.

Furthermore, in the high-pressure steam sterilizer 1 according to an embodiment of the present invention, when air is injected into the sterilization chamber through the air injection unit 50, the drying unit 70 converts the water stored in the water storage tank to high pressure. and the water is discharged sequentially through the ejector 60 and the discharge line 2, and in the process of discharging the water, low pressure is generated on the ejector 60 side, so steam, air, and moisture in the sterilization chamber are discharged in the fifth Since it can be discharged through the connection line 61, the ejector 60, and the discharge line 2 at high speed, there is an advantage in that the drying efficiency of the sterilized material can be significantly improved compared to the prior art.

In particular, in a steam sterilizer, the sterilization chamber must be kept in an ideal vacuum state, but when air is injected into the sterilization chamber through the air injection unit 50, the sterilization chamber is converted from a vacuum state to an atmospheric pressure state, and the vacuum degree is lowered. In the high-pressure steam sterilizer 1 according to an embodiment of the present invention, an oilless pump, which is a converter 40, inhales and discharges air existing in the sterilization chamber by the operation of the air injection unit 50 to clean the sterilization chamber. It is possible to quickly convert to a vacuum state to prevent the deterioration of sterilization and drying power for sterilized objects, and this has the advantage of being able to transfer the heat necessary for drying and sterilization to all parts of all sterilized objects put into the sterilization room. . Furthermore, there is also an advantage that heat can be allowed to penetrate into the space between the sterilized objects overlapping each other in the upward and downward directions in the sterilization room by making the atmospheric pressure into a vacuum state.

Subsequently, after the sterilization operation is completed, air is injected into the sterilization chamber through the air injection unit 50 to completely release the vacuum state of the sterilization chamber, and after lowering the temperature of the sterilization chamber to a certain temperature or less, sterilization is performed. will withdraw

For example, the high-pressure steam sterilizer 1 according to an embodiment of the present invention maintains the temperature of the sterilization room at a high temperature of about 110° C. to 130° C. or more for about 3 minutes to 20 minutes, and maintains the temperature of the sterilization room in a vacuum state for about 3 minutes. After holding for 10 minutes to 10 minutes, air is introduced to temporarily release the vacuum, and the vacuum and non-vacuum conditions are repeated a total of 3 to 5 times, and finally, the sterilization operation is completed while completely releasing the vacuum. can At this time, when the vacuum state is temporarily released, the high temperature should be maintained, and when the vacuum state is completely released, the temperature is lowered through cooling.

After all, according to an embodiment of the present invention, it is possible to sterilize the sterilized objects accommodated in the sterilization chamber by applying heat using steam.

At this time, the aforementioned steam supply unit 20, vacuum unit 30, conversion unit 40, air injection unit, drying unit 70, oilless pump, first control valve 21a to fifth control valve 61a ) is driven by the steam supply mode, vacuum mode, conversion mode, air injection mode, drying unit 70 operation mode, oilless pump operation mode, the first control valve 21a to the fifth control valve 61a input to the control unit. ) is automatically controlled by the on/off mode control program.

At this time, a plurality of buried holes may be applied and arranged to be spaced apart from each other by a predetermined distance.

Also, the buried hole is disposed lower than the support plate 84 .

Accordingly, the first discharge fan 87 sucks foreign substances that are separated from the sterilized water and fall through the passage hole 84a and discharges them to the outside of the housing 81 .

The pedestals 88 are composed of two pairs and disposed to face each other on the upper surface of the horizontal plate 101 with the housing 81 interposed therebetween.

The rail parts 89 are vertically disposed on the upper surface of the pedestal 88, respectively.

The pressing portion 91 may be formed of a metal material so that the first elastic support portion 83 and the second elastic support portion 86 contract and expand by applying sufficient impact force to the cover portion 85 .

The second discharge fans 92 are buried in the buried holes formed in the vertical direction of the pressing part 91, respectively.

Therefore, the second discharge fan 92 sucks foreign substances separated from the sterilized objects in a state disposed above the sterilized objects and discharges them to the outside of the housing 81 .

The rollers 93 are composed of two pairs and each support the lower surface of the upper horizontal portion 90a.

The action of the roller 93 will be described in detail below.

The lifting cylinder 94 raises the pressing part 91, and the release cylinder 95 lowers the raised pressing part 91.

The elevating cylinders 94 are composed of two pairs and are respectively disposed on one side of the pedestal 88.

The elevating cylinder 94 is formed as a hydraulic cylinder. Accordingly, the piston of the lifting cylinder 94 is raised when hydraulic pressure is injected. Then, when the piston is raised, the lifting operation part 90 and the pressing part 91 are raised together to a certain height by the roller 93. Due to this, the pressing part 91 is spaced apart from the upper side of the lid part 85 at a certain height.

On the other hand, the release cylinder 95 is configured to hit the lid part 85 by dropping the pressing part 91 raised by the lifting cylinder.

The release cylinder 95 is used while mounted on the horizontal plate 101.

The release cylinder 95 may be formed as a rodless cylinder or a linear cylinder.

In addition, rails (not shown) may be disposed on one side and the other side of the release cylinder 95, and a pair of lift actuating units respectively sliding along the rail may be formed on the bottom surface of the mounting plate 941.

The release cylinder 95 moves the lift cylinder 94 in the horizontal direction when the lift cylinder 94 separates the pressing part 91 upward from the cover part 85 to move the roller 93 to the lift operation part ( 90) to leave. Accordingly, the pressing portion 91 is dropped to lower the cover portion 85 .

At this time, the lifting cylinder 94 and the release cylinder 95 may be controlled by a remote controller.

The remote control includes a first button for raising the piston and roller 93 by supplying hydraulic pressure to the lifting cylinder 94, and a piston and roller by discharging the hydraulic pressure in the lifting cylinder 94 and transferring the hydraulic pressure to a hydraulic tank (not shown).

And, when the cover part 85 is lowered by the pressing part 91, the second elastic support part 86 is compressed while the support plate 84 is lowered, and the support plate 84 is lowered while the first elastic support part 83 is lowered. to compress

Therefore, the first elastic support portion 83 and the second elastic support portion 86 are repeatedly compressed and expanded by their own elastic force, so that the support plate 84 is operated by the first elastic support portion 83 and the second elastic support portion 86. ), it repeatedly fluctuates in the up and down directions.

Due to this, the sterilized materials seated on the upper surface of the support plate 84 also fluctuate in the upward and downward directions. In addition, some of the sterilized objects repeatedly collide with the support plate 84, and the sterilized objects stacked up and down collide with each other.

By this collision, light foreign substances such as dust on the surface of the sterilized objects are separated. Some of the separated foreign substances fall through the passage holes 84a and are discharged through the first discharge fan 87, while others are scattered and discharged through the second discharge fan 92.

Furthermore, since the sterilized objects such as scalpels, forceps, and tweezers are all metal materials having a certain weight, when the sterilized objects collide with each other, the patient's blood or liquid medical substances hardened on the surface are stochastically broken and removed from the sterilized objects. Separated.

And, some of the separated blood or medical substances are discharged to the outside by the first discharge fan 87 and the second discharge fan 92.

In addition, when the expansion and contraction operation of the first elastic support part 83 and the second elastic support part 86 stops or the expansion and contraction range becomes weak as a certain time elapses, the second button and the third button are sequentially pressed. Press the roller 93 and the lift cylinder 94 to the lower side of the upper horizontal part 90a, and then press the first button and the fourth button in sequence so that the pressing part 91 hits the cover part 85 again. you just have to do it

On the other hand, when the thickness of the first elastic support portion 83 and the second elastic support portion 86 is large and the number of applications is large, or when the number of sterilized materials seated on the support plate 84 is large, the cover portion is applied only by the pressing portion 91. Even if 85 is hit, the first elastic support part 83 and the second elastic support part 86 may not be contracted or expanded to the maximum value.

To prevent this, a reservoir 96 and a pump 97 are applied.

The storage tank 96 and the pump 97 are pressurized when the first elastic support part 83 and the second elastic support part 86 are thick and the number of applications is large or when the number of sterilized substances seated on the support plate 84 is large. It is a configuration in which the weight of the portion 91 is varied to increase the impact force on the cover portion 85. That is, by increasing the weight of the pressing unit 91 through the reservoir 96 and the pump 97, the first elastic support unit 83 and the second elastic support unit 86 can be contracted or expanded to a maximum value.

The storage tank 96 is disposed on the upper surface of the pressing part 91 . The reservoir 96 may be coupled to the upper surface of the pressing part 91 through bolts.

At this time, the storage tank 96 is installed at a position that does not block the buried hole of the pressing part 91 so as not to block foreign substances discharged through the second discharge fan 92 .

For example, the buried hole of the pressurization part 91 may be formed in the center of the pressurization part 91, and the storage tank 96 may be installed at the edge of the upper surface of the pressurization part 91.

An inlet 96a for receiving water from the pump 97 is formed on one side of the storage tank 96 .

The pump 97 may be mounted on the ground where the high-pressure steam sterilizer 1 is placed or mounted on the aforementioned mobile cart.

The pump 97 is connected to a separate water storage tank (not shown) and the storage tank 96 provided on one side through a connection hose H, respectively, and supplies the water stored in the water storage tank to the inside of the storage tank 96. The water in the storage tank 96 may be supplied or transferred to the water storage tank.

When water is supplied to the inside of the storage tank 96 by the pump 97, the impact force of the pressurizing part 91 on the cover part 85 becomes stronger, and when the water in the storage tank 96 is discharged, the pressure against the cover part 85 increases. The hitting force of the pressing part 91 becomes relatively weak.

Therefore, when the thickness of the first elastic support portion 83 and the second elastic support portion 86 is thick and the number of applications is large, or when the number of sterilized materials seated on the support plate 84 is large, the storage tank ( Water is additionally supplied to 96) to increase the impact force of the pressing part 91 against the cover part 85.

And, as the weight of the pressing unit 91 can be selectively and freely increased or decreased through the pump 97, the thickness of the first elastic support unit 83 and the second elastic support unit 86, the number of applications, and sterilization The amount of water supplied to the storage tank 96 may be appropriately adjusted according to the number of water.
