Description

[0001] STERILIZER WITH FUNCTION OF STERILIZATION CABINET [0002]

The present invention relates to a sterilization apparatus including a sterilization pouch and a storage function. More particularly, the present invention relates to a sterilization apparatus that stores a sterilized sterilized product in a sterilization chamber so that the sterilized state can be maintained even when the sterilized product is used. And a sterilizing device including a storage function.

Sterilization refers to a high level of treatment in that it means completely eliminating all living microorganisms through physical and chemical action, unlike cleaning or disinfection. Therefore, microorganisms such as various types of instruments, glass products, magnetic products, metal products, rubber, plastics, paper, fibers, reagents, water and the like which are present in various types of sterilized products including sterilized products including temperature and pressure sensitive products are sterilized Medical, industrial, and agricultural products. Typical devices include a high pressure steam sterilization device, an ethylene oxide (EO) gas sterilization device, a plasma sterilization device, and the like, which can not be sterilized by a high pressure steam sterilization device, are sterilized by an EO gas or a plasma sterilization device.

This type of sterilization is one step higher than sterilization, and sterilization is carried out by using a sterilization apparatus when sterilization is not possible even if microorganisms such as microorganisms are sterilized by a sterilization machine. Therefore, a sterilization apparatus was used to sterilize various parts, industrial products, utensils, clothing, and agricultural products. Especially in hospitals, sterilization equipment is used to sterilize surgical instruments, examination equipment, and clothes. Typically, the sterilizing apparatus is classified into a low-temperature sterilizer and a high-temperature sterilizer, and the low-temperature sterilizer includes a plasma sterilizer and an E.O gas sterilizer. The low temperature plasma sterilizer is known to be unable to sterilize water and some clothes, and the equipment price is high but the sterilization time is as short as about 30 minutes. Since the high-pressure steam sterilizer is sterilized at a high temperature and a high pressure from 120 to 140 degrees, the sterilized article is limited.

Patent Document 1 discloses a steam sterilizer incorporating an ultraviolet irradiator. A steam sterilizer incorporating an ultraviolet irradiator of Patent Document 1 sterilizes the bottom surface, wall surface, and ceiling of a room, Is equipped with an ultraviolet irradiator for sterilizing the pathogenic microorganisms contained in the condensate by re-heating the re-condensed condensed water after re-heating and then re-using the condensed water for sterilization of the indoor wall surface.

However, sterilization apparatuses, which are generally used as sterilizers, when the sterilization is completed, a buzzer sounds that the sterilization is completed in the controller apparatus, and all operations are stopped. In the case of a high-pressure steam sterilization apparatus, if the sterilized article is not taken out of the sterilization chamber after completion of the sterilization, moisture may be generated inside the sterilization chamber. In addition, there is a case where the sterilization is not completed after sterilization is completed. All medical sterilizers should be kept in a sterile pouch after the sterilization cycle. Furthermore, in a case where a lot of operations such as dentistry or ophthalmology are performed, it is troublesome to store the microorganisms or virus bacteria in sterilized pouches or sterilized disposable packs, there is a problem.

Furthermore, sterilization apparatuses generally can not store sterilized objects in the sterilization chamber because they are turned off after sterilization or left in a sterilized state without controlling the sterilization chamber. The reason is that the inside of the sterilization chamber does not enter the light, and the inside of the sterilization chamber often becomes humid over time. Also, in the case of a high-pressure steam sterilizer, malaise occurs due to the difference between the temperature inside the sterilization chamber and the room temperature after completion of the sterilization. Normally, since the sterilization chamber is at atmospheric pressure in order to sterilize the sterilization chamber once the sterilization is completed, the humidity, temperature, and air pressure inside the sterilization chamber maintain a good environment for propagating microorganisms. Therefore, if there is sterilized water in the sterilization chamber, the sterilization apparatus must be restarted every time the sterilization chamber is opened. Therefore, the operation of the sterilization apparatus is not preferable because of the high cost and time consuming. Therefore, when the sterilization apparatus is stored in the sterilization chamber for a long period of time without sterilization after the completion of the sterilization, the inside of the sterilization chamber is humid and the temperature is changed, Environment.

In addition, in the case of using the sterilized product in the sterilization chamber, the air in the room enters the sterilization chamber in the process of taking out some sterilized products in the sterilization chamber, or the microorganisms in the hand enter the sterilization chamber and become parasitic.

In the following description of the embodiments, a detailed description of related arts will be omitted if it is determined that the gist of the embodiments may be unnecessarily blurred.

FIG. 1 is a schematic view showing a schematic configuration of a sterilizing apparatus including a sterilizing storage function according to the present invention.

Referring to FIG. 1, a sterilization apparatus 100 including a sterilization storage function according to the present invention includes a sterilization chamber 110 having a chamber defined therein; A door 200 for opening the chamber; A heater 600 installed in the sterilizing chamber 110 and heating the sterilizing chamber 110; A vacuum pump 150 connected to the sterilization chamber 110 and selectively pressurizing the sterilization chamber 110; A door sensor 210 for sensing opening and closing of the door 200; And a controller (not shown) for controlling the operation of the heater 600 and the vacuum pump 150.

The sterilization chamber 110 is formed with a chamber in which a sterilized object requiring sterilization is stored and one side is opened by a door 200. A sterilization chamber 110 is formed on one side of a front surface of the sterilization chamber 110, (Not shown) for displaying an internal state of the display device.

The door 200 is provided with a door sensor 210 for sensing the operation of the door 200. The door 200 can detect that the sterilized object is drawn in and out and has a gasket The sterilization operation of the sterilization apparatus 100 is automatically operated according to the on or off of the door 200. When the door 200 is turned off, ) Is stably sealed.

Plasma electrode plates 120 are formed at predetermined intervals along the inner surface of the sterilizing chamber 110 and the plasma electrode plate 120 is connected to an external plasma generator 700.

In other words, the reflection plate 170 and the plasma electrode plate 120 are disposed inside the door 200 of the sterilizing chamber 110 to reflect the zigzag ray. Assuming that a hand or other force is brought into contact with the sterilizing material and there is a bacterial microorganism when the sterilized water in the sterilization chamber 110 is to be discharged out of the sterilization chamber 110 by a human hand or the like, The sterilized water remaining in the chamber 110 may be infected with the microorganisms and the bacterial microorganisms may proliferate.

However, in the present invention, by controlling the temperature, humidity and pressure inside the sterilization chamber 110, bacterial growth is suppressed in the sterilized product, and diffuse reflection is caused by the reflection plate 170 to effectively transmit ultraviolet rays to the ultraviolet lamp 160 for a certain period of time It is sterilized by sterilizing the pathogenic bacteria.

In addition, according to the present invention, a catalytic agent may be included in the inside of the supply tube that is introduced into the sterilizing chamber 110 by the plasma generator 700, as the case may be. In the catalyst, the catalyst may be coated with an oxide catalyst on the surface of the alumina particles, and the oxide catalyst may include vanadium oxide (V2O5).

Such a catalyst serves to generate sterilizing gases such as ozone, active oxygen, and hydroxy radicals by the plasma discharged inside the supply pipe. The plasma discharge generated in the discharge plasma tube 153 is made into a surface discharge type so that the plasma discharge can be performed well even if the voltage is low, and the plasma discharge can be stably maintained even at the atmospheric pressure.

A heater 600 for applying heat to the sterilization chamber 110 is formed on the inner wall of the sterilization chamber 110 and a thermometer 300 for sensing the temperature in the sterilization chamber 110 and a heater A pressure gauge 400 for sensing the pressure is formed.

When the door sensor 210 does not operate after the sterilization process is completed in the sterilization chamber 110, the control unit (not shown) drives the vacuum pump 150 to maintain a predetermined constant pressure, and the heater 600 To control the temperature in the sterilizing chamber 110 or to control the humidity in the sterilizing chamber 110 with the vacuum pump 150 or the heater 600. [ This makes it possible to measure the humidity in the sterilizing chamber 110 through the humidity sensor 170 mounted on the predetermined portion of the sterilizing chamber 110.

An ultraviolet lamp 160 for generating ultraviolet rays for sterilization is mounted on the inner surface of the sterilizing chamber 110 facing the door 200 through a ramp racket 161.

Since the ultraviolet lamp 160 is required to be in contact with a fluid such as water, the ultraviolet lamp 160 needs to have excellent impact resistance and water repellency. Therefore, the ultraviolet lamp 160 has a high ultraviolet transmittance, It is possible to prevent direct contact with the lamp.

The ultraviolet lamp 100 is a lamp that emits ultraviolet rays. The ultraviolet lamp 100 can be divided into four types of UV-A, UV-B, UV-C and UV-D. Among them, the wavelength of 253.7 nm is known to be almost the same as the wavelength most lethal to the DNA of bacteria or viruses.

The wavelength emitted from the ultraviolet lamp 160 of the present invention should preferably be the above-mentioned wavelength, and this wavelength affects the DNA of bacteria or viruses and changes almost deadly or harmlessly to prevent reproduction. These bacteria and viruses are especially vulnerable to ultraviolet rays, so ultraviolet sterilization methods can be effective and have a shorter disinfection time (2 to 7 seconds for bacteria) than other disinfection methods. There is advantage in not staying.

A sterilizing agent supply device 500 is formed on the outer side of the sterilizing chamber 110 to supply the sterilizing agent for sterilizing the sterilizing product into the chamber of the sterilizing chamber 110. The sterilizing feeder 500 includes a sterilizer vaporizer for heating and evaporating the sterilizing agent, a sterilizing agent storage container, and a second valve V2 controlled to be inserted into the sterilizing agent.

As the sterilizing agent, various materials having sterilizing power such as hydrogen peroxide can be used, and the sterilizing agent heating temperature can be set at various temperatures at which the sterilizing agent can be sufficiently evaporated, such as about 10 to 120 ° C.

For example, when hydrogen peroxide is used as a sterilizing agent, hydrogen peroxide can be gradually evaporated to sterilize the inside and the outside of the endoscope 10 effectively. For example, when hydrogen peroxide is gradually heated at 60 to 120 DEG C starting at 10 to 25 DEG C, the surface of the endoscope 10 is sterilized with the hydrogen peroxide vapor at a low concentration generated at the early stage, and sterilization with hydrogen peroxide vapor at a high concentration The inner tubes 14, 15, 16 and 17 of the endoscope can be sterilized. Of course, the sterilizing agent used for sterilization in the present invention is not limited to hydrogen peroxide, and the heating temperature of the sterilizing agent is not limited to the above.

A reflection plate 170 having a diffuse reflection function is formed on the inner side surface of the door 200. According to the present invention, the reflection plate 170 may be formed of a UV-reflective multilayer structure film and may be formed into a polygonal shape such as a circle, a triangle, or a rectangle. The polygonal-shaped structural film having a polygonal shape including the circular shape has a plurality of reflection surfaces formed on its surface for reflecting light rays at multiple angles so as to cause reflection and scattering of ultraviolet light incident on the film in multiple directions have.

Therefore, compared with general one-dimensional reflective structural films, it is possible to sterilize effectively at low power by maximizing the irradiation area even in a narrow space, and it is easy to apply it inexpensively to various fields.

Hereinafter, the operation of the sterilization apparatus including the sterilization storage function according to the present invention will be described in detail.

FIG. 2 is a flowchart illustrating an operation of a sterilization apparatus including a sterilization storage function according to the present invention.

Referring to FIG. 2 together with FIG. 1, the operation of the sterilization apparatus according to the present invention is roughly divided into a sterilization process and a sterilization process.

First, the sterilization process will be described. A user opens the door 200 and stores the sterilized product in the sterilization chamber 110 of the sterilization apparatus 100 (S1).

At this time, the sterilizing apparatus 100 senses the on / off state of the door 200 through the door sensor 210 mounted on the door 200 and operates automatically so that the sterilizing apparatus 100 Sterilization is performed in the sterilization chamber 110 according to a preset sterilization cycle (S2, S3). Thereafter, when the sterilization process of the sterilized product is completed, it is displayed through the buzzer or the display unit to inform that the sterilization is completed.

If the user manually inserts the sterilized water into the sterilization chamber 110 and closes the door 200 and operates the sterilization apparatus 100, the sterilization cycle proceeds according to a predetermined cycle (process), and the sterilization is completed , It informs that the sterilization is completed through buzzer or alarm.

The sterilization process of the sterilization apparatus 100 will be described. After the sterilization process is completed as described above, the controller checks whether a door switch (not shown) is operated by the door sensor 210.

When the door switch is turned off, it is determined that the sterilized sterilized object is stored in the sterilization chamber 110 (S4), the operation time of the ultraviolet sterilizer (not shown) is checked, The operation of the ultraviolet sterilizer is stopped and the temperature, humidity, and pressure inside the sterilizing chamber 110 are set to a predetermined value by operating the vacuum pump 150 to lower the pressure inside the sterilizing chamber by a predetermined sterilization and storage cycle operation When the pressure is reached, the operation is stopped to control the temperature and the humidity, so that the sterilization chamber is equipped with the storage function of the sterilized product (S5).

If the door sensor 210 detects that the door 200 is opened, it recognizes that the sterilized water in the sterilization chamber 110 is drawn out, operates the vacuum pump 150 (S8 The door 200 is opened (S9, S10) after the pressure inside the sterilization chamber 110 is raised and maintained at 0.2 atmospheres to prevent the air in the room from being introduced into the sterilization chamber 110. [ Since this operation is performed instantaneously, the user hardly feels it.

Specifically, the air in the sterilizing chamber 110 is first opened through the vacuum pump 150 to the outside of the sterilizing chamber 110 by opening the sixth valve V6 and the first valve V1. Then, the air is measured through the pressure gauge 400 When it reaches the preset vacuum pressure, it stops and removes the air inside the sterilization chamber. The heater 600 outside the sterilizing chamber 110 is heated to control the inside temperature of the sterilizing chamber 110 and the humidity sensor 162 through the controller to maintain a proper humidity.

Further, the vacuum pump 150 is operated to lower the temperature and the humidity in the sterilization chamber at the same time. According to the present invention, the vacuum pump 150 outside the sterilizing chamber can control the pressure, the amount of air, the temperature and the humidity in the sterilizing chamber 110 through a suitable degree of vacuum and the heater 600 in the sterilizing chamber 110.

When the inside of the sterilizing chamber 110 is pressed, the vacuum pump 150 is rotated in the reverse direction to operate the fifth valve V5 and the first valve V1, (Not shown) to suck air into the sterilizing chamber 110, thereby preventing the bacterial microorganisms in the room air from entering the sterilizing chamber 110.

Then, when the door 200 is opened, the ultraviolet sterilizer operates to sterilize a source of contamination such as microorganisms entering the sterilization chamber 110 by a hand or other device through the ultraviolet lamp 160 by ultraviolet rays.

At this time, the inner wall of the sterilizing chamber 110 can be sterilized by nearly 100% since the reflector 170 having the ultraviolet rays is diffused. When the door 200 is closed after the sterilized water in the sterilization chamber 110 is drawn out, the controller determines whether there is sterilized water remaining in the sterilization chamber 110. If there is no sterilized water, the controller terminates the sterilization storage function S6, S7).

The storage of the sterilized product in the sterilization chamber 110 can be resolved by mounting a load cell (not shown) on the tray in the sterilization chamber 110. That is, in the case of a high-pressure steam sterilizer, it is preferable to install a high-temperature load cell because the temperature in the sterilization chamber 110 exceeds 120 degrees and it is difficult to install a general load cell.

Therefore, when the door 200 is closed with sterilized water in the sterilization chamber 110, the controller automatically performs the sterilization storage function. When the sterilization chamber 110 is not sterilized, The controller terminates the function of the sterilization apparatus 100 and terminates all the cycles of the sterilization process by stopping the sterilization storage function.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.

Therefore, the spirit of the present invention should not be construed as being limited to the above-described embodiments, and all of the equivalents or equivalents of the claims, as well as the following claims, I will say.
