Description

{Package Film and Vacuum Resin Package Bag}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sterilizing film capable of generating plasma, and more particularly, to a packaging material capable of sterilizing by generating a plasma in a bag.

Japanese Patent Laid-Open No. 2008-183025 discloses a plasma sterilization apparatus by generating an atmospheric pressure dielectric barrier discharge (DBD) using a breathable packing material. (O ₃ ) or hydroxyl (O ₃ ) ions generated by excitation of the water vapor component in the air by an oxygen radical directly generated by dielectric barrier discharge inside or an ultraviolet ray (UV-ray) OH-), hydrogen peroxide (H ₂ O ₂ ), and the like. However, 2008-183025 can not discharge in a vacuum state.

Korean Patent No. 10-1012442 discloses a sterilizing apparatus using atmospheric pressure plasma. However, the packaging material of Korean Patent No. 10-1012442 is incapable of securing electrical safety due to exposure of high voltage and generation of electromagnetic wave, and is not applicable to sterilization apparatus as disclosed in Japanese Patent Laid-Open No. 2008-183025.

In the application of medical sterilization packaging materials, existing packaging materials perform only the basic functions of preventing and storing secondary contamination of sterilized medical devices. In the sterilization of reusable medical devices in medical institutions, there are various medical packaging materials used for carrying out the sterilization process using a medical sterilizer and thereafter for storage. In order to prevent secondary contamination, packaging materials with selective permeability to the sterilizing agent defined in each sterilizer may be used to sterilize the medical device in a packaged state after packaging. For example, a packaging material made of woven, non-woven, paper, polypropylene or the like can be used for a high-pressure steam sterilizer. In the case of an ethylene oxide (EtO) sterilizer, a polymer-based packaging container made of polyethylene or Tyvek can be used.

Medical sterilizers are required to achieve a sterilization of a medical device that performs a proven process, i.e., sterilization, to provide a microorganism-free medical device. A typical medical sterilizer includes a high pressure steam sterilizer and sterilization is performed at a high temperature of about 134 degrees centigrade and a high pressure of about 2 bar. It has a limitation that sterilization can not be performed for medical devices whose use in high-temperature and high-pressure processes is limited, such as in food sterilization. Further, in order to perform the sterilization by the steam, the medical device is further restricted by water due to corrosion and the like. The dry heat sterilizer for eliminating the restriction by moisture is sterilized at a high temperature of about 180 degrees Celsius. However, it has a disadvantage that it can not be applied to a medical device including a material part such as plastic which is vulnerable to heat.

Recently, a chemical sterilizer has been developed for the sterilization of medical devices which are susceptible to high temperature, high pressure and humidity, and a typical example is an ethylene oxide sterilizer. However, due to the toxicity of ethylene oxide gas, proper management is required. After sterilization, it must be precisely 8 hours or more precisely. Due to the recent risk of ethylene oxide gas, some countries restrict the use of ethylene oxide . A plasma sterilizer has been developed and commercialized as an environmentally friendly chemical sterilizer that replaces this. However, chemical sterilizers can also have secondary contamination problems that can occur in the packaging process after sterilization.

In order to solve the secondary pollution problem, special packaging film such as Tyvek was developed. However, the sterilization process performed on the medical device in the packaged state is inevitably limited in the permeability of the sterilant, and a long sterilization time of about one hour is required to ensure sterilization reliability.

In addition, the primary contamination of the packaging material may affect the permeability of the sterilizing material, and the sterilizing reliability may be lowered. In addition, the existing chemical sterilizer is in the process of sterilization chamber, and the size of the sterilizer is too large to be introduced due to lack of space in the medical institution, and it is difficult to introduce the technology due to expensive equipment.

Therefore, secondary contamination can be prevented through plasma sterilization in the inside of the packaging container, and there is no restriction on the permeability of the packaging material, so that a high sterilizing power can be obtained. By commercialization of this technology, it can be performed inside the packaging material instead of the existing sterilizer chamber, which can increase the space utilization and can be applied as an economical and innovative sterilizer by simplifying the equipment.

In the conventional plasma sterilization apparatus, the object to be processed is placed in the fixed chamber, and a plasma is formed and sterilized.

According to one embodiment of the present invention, a dielectric discharge plasma is formed by inserting an object to be processed into a vacuum resin packaging container and evacuating the material under vacuum, thereby providing a sterilizing agent, ultraviolet rays, and plasma to the object to be processed, The treated material can be heated to form optimal sterilization process conditions. In addition, in the vacuum state, the external plasma source generates a plasma to provide a sterilizing agent containing hydrogen peroxide or nitrogen and oxygen reactive species (RONS) through the valve or connecting pipe of the vacuum resin packaging container , The object to be treated can be sterilized. The external plasma source generates large amounts of nitrogen and oxygen active species to sterilize the material to be treated. In addition, in the state where the vacuum resin container is evacuated to vacuum, the pattern electrode integrated in the vacuum resin packaging container secures a discharge space and an exhaust passage to form a dielectric discharge plasma, and the sterilization process can be performed. In particular, the dielectric discharge plasma can sterilize the article to be treated and heat the article to a temperature for an optimal sterilization process.

When the vacuum resin packaging container is exhausted using an external plasma source and a vacuum pump and a sterilizing agent is supplied, the surface of the vacuum resin packaging container is required to be subjected to an embossing treatment for efficient exhausting. When the vacuum packaging container includes an embossing film, it is difficult to form a pattern electrode for discharging a dielectric barrier on the embossing film. According to one embodiment of the present invention, a dielectric pattern film is used which secures a discharge space in the packaging film and provides an exhaust passage.

Separate dielectric barrier discharges in the vacuum plastic packaging container generate nitrogen and oxygen active species at a pressure lower than atmospheric pressure to increase the diffusion rate and reduce losses due to surface recombination of the sterilizing agent to a deep position The sterilizing agent can be efficiently delivered.

In a vacuum resin packaging container, when the vacuum state is under atmospheric pressure, dielectric barrier discharge easily occurs even at low electric power. The internal discharge of the external plasma source and the vacuum resin packaging container itself can improve the sterilizing ability. Particularly, it is suitable for sterilizing medical equipment requiring high sterilizing ability. Such a combined sterilization by the external plasma source and the inner plasma source can significantly reduce the sterilization or sterilization process time, and a separate cooling process is not required in the pasteurization process. In addition, in the case of high temperature sterilization, it is possible to sterilize plastic medical devices which can not be applied due to thermal deformation. Further, since a vacuum packaging container capable of generating plasma is used, a separate vacuum packaging process is unnecessary. The vacuum resin packaging container according to an embodiment of the present invention can save space as compared with a high-temperature high-pressure sterilizer and can shorten the sterilization time by effectively sterilizing at a low temperature. The vacuum packaging process and the sterilization process are simultaneously performed, Secondary contamination and cross contamination are prevented, thereby reducing the possibility of medical accidents.

According to one embodiment of the present invention, a packaging film of a PET / AL / PE structure including a conventional aluminum foil film is used. A separate dielectric pattern film is formed of a resin film and includes a pattern area which is recessed or protruded on its surface. The pattern electrodes are selectively stacked on the protruding portions connected to each other in the pattern region or the concave portions connected to each other. The packaging film of the PET / AL / PE structure and the dielectric pattern film may be laminated together through a thermocompression bonding process or an adhesive. The dielectric pattern film may be formed using a molding method such as compression molding or injection molding. In addition, the pattern electrode may be formed using an electroplating or electroless plating method.

However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are being provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

The AC power supply unit 20 can output AC power of a low frequency (1 kHz to 100 kHz). The waveform of the external power supply 160 may be any of a sine wave, a square wave, and a pulse. The peak voltage is driven within the dielectric breakdown voltage of the dielectric barrier used and is usually from 1 kV to 10 kV. There is an optimum temperature for sterilization, and usually the optimum temperature is about 55 degrees Celsius. Therefore, in order to heat the object to be processed or the vacuum resin packaging container to the optimum temperature, the output of the AC power supply unit 20 may be switched to several Hz or less to maintain the optimum temperature. The temperature of the object to be processed or the vacuum resin packaging container is measured through a temperature sensor 23, and the measured temperature can be used to control the AC power supply unit 20. [ The temperature sensor 23 may be a contact type temperature sensor or a non-contact type temperature sensor.

The vacuum resin packaging container 100 may be a sealed and flexible bag shape. The vacuum resin packaging container 100 may include a pattern electrode 116 for performing a dielectric barrier discharge therein. The vacuum resin packaging container may include a valve 106 or a connecting pipe for evacuation to a vacuum state after being sealed.

The valve 106 may be a check valve that provides a flow of air in one direction. When the connector 19 is coupled to the valve 106 to exhaust the vacuum resin packaging container 100, the valve 106 is opened by a pusher 106a, and the vacuum pump 14 The vacuum resin packaging container 100 is evacuated. When the connector 19 is coupled to the valve, the valve 106 is opened by the pusher 19a and the outer plasma source 13 is opened by the pusher 19a to fill the vacuum resin packaging container 100 with the sterilizing agent. Provides the sterilant to the inside of the vacuum resin packaging container 100 through the connector 19 and the valve 106. When the connector 19 is removed from the vacuum resin packaging container 100 in a vacuum state, the check valve operates to block external air from flowing into the vacuum resin packaging container.

The external plasma source 13 may perform atmospheric pressure discharge or a high pressure discharge between several hundred milliTorr and atmospheric pressure. The external plasma source 13 may be discharged using air or hydrogen peroxide to produce a sterilizing agent. The sterilizing agent may include nitrogen and reactive oxygen and nitrogen species (RONS). The external plasma source 13 may be any one of a glow plasma discharge using an electrode, an inductively coupled plasma discharge using an antenna, a microwave plasma discharge using a microwave, or a dielectric barrier discharge using an AC power.

The vacuum pump 14 may be a low vacuum pump for discharging the vacuum resin packaging container 100.

The vacuum resin packaging container 100 may include a passage pipe or valve 106 for providing a passage for venting air to be connected to the external plasma source 13 and the vacuum pump 14. The output of the valve 106 branches to two branches, one branch is connected to the vacuum pump 14 via a vacuum pump input valve 11 and the other branch is connected to an external plasma Can be connected to the source (13). The input of the external plasma source 13 is connected to an external plasma source input valve 15 and the external plasma source input valve 15 is coupled to the output of the vacuum pump and may be connected to the exhaust valve 16 . The exhaust valve may discharge gas to the atmosphere. The vacuum pump 14 and the external plasma source 13 may be connected in parallel to each other to circulate gas.

 In order to sterilize the vacuum resin packaging container 100, the object to be processed 2 is inserted into the vacuum resin packaging container, and the edges of the first packaging film and the second packaging film overlapped are thermo- . The vacuum resin packaging container 100 may be pre-sealed so as to have an opening to allow the object 2 to be inserted therein. Preliminary sealing of the vacuum resin packaging container 100 may be performed by thermocompression bonding or may be sealed using an adhesive. After inserting the object 2 through the opening, the opening may be sealed through thermocompression bonding or an adhesive.

Then, the vacuum resin packaging container 100 may be exhausted using a valve or a connecting pipe. As the connector 18 is connected to the valve 106, the valve 106 can be set to the open state. When the connector 106 is removed, the valve can be set to the closed state.

The vacuum pump 14 can discharge the pressure of the vacuum resin packaging container 100 to a level of several hundred milliTorr to several torr. The exhaust path of the vacuum pump 14 is connected to the valve 106, a vacuum pump input valve 11 disposed at the suction port of the vacuum pump, a vacuum pump 14, and an exhaust valve 16 connected to the exhaust port of the vacuum pump ). Accordingly, the air inside the packaging container can be discharged through the exhaust valve 16 to the outside. When the pressure of the packaging container is exhausted to a set pressure below atmospheric pressure, the exhaust valve 16 may be closed.

Then, a dielectric barrier discharge can be performed on the exhaust passage connected to each other on the surface of the first packaging film 110 in a vacuum state. The vacuum resin packaging container may include an exhaust passage including a pattern continuously connected to the inner surface thereof for efficient exhaust. In addition, when the vacuum packaging container 100 is in a vacuum state, the exhaust passage may provide a discharge space capable of performing dielectric barrier discharge.

For the dielectric barrier discharge, the vacuum resin packaging container 100 may include the first packaging film 110 and the second packaging film 120. The second packaging film 120 may be a PE resin film and the first packaging film 110 may include a pattern electrode 116 and a ground electrode film 112 facing each other to perform a dielectric barrier discharge. have. The ground electrode film 112 may be in the form of a plate, and the pattern electrodes 116 may be electrodes connected to each other in the form of a porous strand. The shape of the pattern electrode may be a checkered shape in which two straight lines cross each other.

Meanwhile, in order to form the pattern electrode 116 and the exhaust passage on the first packaging film 110 at the same time, the pattern electrode 116 may be in the form of a checkered pattern arranged on the lower surface of the depression. Concretely, an exhaust passage of a trench structure connected to each other is formed, and a thin pattern electrode 116 can be formed on the exhaust passage.

According to a modified embodiment of the present invention, the pattern electrode may be formed on the first packaging film, and the exhaust passage may be formed on the second packaging film. In order to form the exhaust passage in the second packaging film, the second packaging film may be embossed in the form of an island.

When AC power is applied between the ground electrode film 112 and the pattern electrode 116, a dielectric barrier discharge may be formed in the discharge path or a discharge space around the pattern electrode.

The dielectric barrier discharge can be efficiently discharged at a vacuum below atmospheric pressure. The pressure of the vacuum resin packaging container may be from several Torr to several hundreds of milliTorr. The dielectric barrier discharge can effectively generate a sterilizing agent containing ultraviolet rays, ions, nitrogen and reactive oxygen species (RONS) in a vacuum state. The ultraviolet rays, ions, and sterilizing agent can sterilize and sterilize the object 2 to be treated. The dielectric barrier discharge can be maintained after the vacuum packaging container 100 is sealed regardless of the supply of the sterilizing agent from the external plasma source 13. The dielectric barrier discharge may be controlled to be several Hz or less to maintain the vacuum resin packaging container or the object to be processed at an optimal temperature (55 degrees Celsius). For temperature control, the temperature of the vacuum resin packaging container or the object to be processed is measured through the temperature sensor 23, and the measured temperature may be provided to the AC power source unit 20. [

Next, a plasma is generated using an external plasma source 13 to supply a sterilizing agent containing nitrogen and oxygen reactive species (RONS) to the valve 106 or the connection pipe As shown in FIG. The supply path of the sterilant may include an input valve 15 of an external plasma source, an external plasma source 13, an external plasma source supply valve 12, and a valve 106.

Specifically, the vacuum pump 14 and the external plasma source 13 are operated, and the vacuum pump input valve 11 and the exhaust valve 12 are opened. Accordingly, the pressure of the vacuum resin packaging container is reduced to a vacuum state.

Then, when the set vacuum state is reached, the exhaust valve 16 and the vacuum pump input valve 11 are closed. Further, the external plasma source supply valve 12 and the external plasma source input valve 15 are opened to supply sterilizing agent to the vacuum resin packaging container. As a result, the pressure of the vacuum resin packaging container increases.

Subsequently, when the pressure of the vacuum resin packaging container reaches a predetermined pressure below atmospheric pressure, the external plasma source input valve 15 is closed again, and the vacuum pump input valve 11 is opened. As a result, the pressure of the vacuum resin packaging container decreases again.

Subsequently, when the pressure of the vacuum resin packaging container is sufficiently reduced to reach the set reference pressure, the vacuum pump input valve 11 is closed and the external plasma source supply valve 12 is opened. As a result, the pressure of the vacuum resin packaging container increases again. The above pressure increase / decrease operation can be repeated several times.

The step of evacuating the vacuum resin packaging container and the step of providing the sterilant to the vacuum resin packaging container through the external plasma source may be repeated in sequence.

When the sterilization process is completed, the vacuum pump input valve 11 and the external plasma source supply valve 12 are closed, and the operation of the vacuum pump 14 and the external plasma source 13 is stopped. Further, the connector 19 connected to the vacuum packaging container is removed.

During the operation of the external plasma source and the exhaust pump, the dielectric barrier discharge by the first packaging film can be maintained.

FIG. 3B is a cross-sectional view showing the first packaging film of FIG. 2B. FIG.

3C is a cross-sectional view illustrating the packaging container in the vacuum state of FIG. 3A.

The dielectric barrier film 113 and the dielectric pattern film 114 are interwoven with each other.

The first packaging film 110 may be formed by laminating vacuum packaging films 111, 112, and 113 of a PET / Al / PE structure and a dielectric pattern film 114. The first packaging film 110 may include a sealing region 102, a pattern region, and a pad region. The sealing region 102 is formed at the edge of the first packaging film and is joined to the second packaging film to provide an internal sealing space. The pattern region includes depressions connected to each other in a region where a pattern is formed in the dielectric pattern film. The pattern region may provide a discharge space in which the pattern electrode 116 forms a plasma and an exhaust passage through which the gas can escape. The connection pad 104 is disposed in the pad region and is electrically connected to the external AC power source unit 20. [ The connection pad 104 is electrically connected to the pattern electrode 116. The connection pad may be formed simultaneously with the pattern electrode. The pad area or the connection pad 104 is aligned with the pad opening 105 passing through the second packaging film 120. Accordingly, the connection pad 104 is easily brought into electrical contact with the AC power source 20 through contact means such as a clamp. Since the connection pad 104 is exposed to the outside air, it is sealed. That is, the pad region is disposed inside the sealing region.

The packaging material outer layer film 111 may be made of a PET (polyethylene terephthalate) film having flexibility. The material of the packaging film may not be limited to the PET film but may be replaced with another resin.

The ground electrode film 112 may be an aluminum film. The ground electrode film is not limited to aluminum but can be replaced with another metal. The ground electrode film may be electrically grounded. The sealing area of the first packaging film can be picked up by a means such as a crochet tooth clamp to ground the ground electrode film. Alternatively, a portion of the ground electrode film may be exposed by removing a portion of the package outer film from the sealing region 102.

The dielectric barrier film 113 may be a PE (polyethylene) film. The dielectric barrier film may be a PE film. The dielectric barrier film is not limited to PE but can be changed into various resins. The dielectric barrier film intervenes between the ground electrode and the pattern electrode to provide sufficient dielectric breakdown strength.

The dielectric pattern film 116 may be a PE film and may include a depression of a porous screen structure on one surface. The depressed portion may provide an exhaust passage and a discharge space. In addition, pattern electrodes 116 connected to each other may be disposed at the depressed portions. The thickness of the pattern electrode 116 may be sufficiently smaller than the depth of the depression. Specifically, the depth of the recessed portion may be several tens of micrometers to several millimeters. The thickness of the pattern electrode 116 may be 1/3 or less of the depth of the depression. The dielectric pattern film 114 may be a molded PE film. The pattern electrode 116 may be selectively formed in a pattern region of the dielectric pattern film. In order to selectively coat the pattern electrode 116 and the connection pad 104 at the depressed portion, the roughness of the recessed portion of the dielectric pattern film may be larger than the roughness of the protruded portion. And may be selectively plated on the depressed portion in an electroless manner.

The pattern regions may be formed so as to be continuously connected to each other on the surface of the dielectric pattern film 114, and the pattern electrodes 116 may be disposed in the recessed pattern region.

The pattern electrode 116 may be formed on the lower surface of the depression and may have a porous screen structure. The shape of the pattern electrode 116 may be a shape including a hole arranged in a mesh shape or a matrix shape. The shape of the hole may be a circle, a polygon, a slit, or a serpentine slit shape. The diameter or width of the hole may be 0.3 mm to 3 mm in diameter of the through-hole of the perforated screen. The thickness of the pattern electrode 116 may be several micrometers to several hundreds of micrometers. The thickness of the pattern electrode 116 may be smaller than the depth of the depression. Thus, the exhaust passage and the discharge space can be ensured. The pattern electrode 116 may include at least one of copper, nickel, gold, silver, and aluminum.

The dielectric pattern film 116 on which the pattern electrode 116 is formed may be laminated to the laminated outer film / ground electrode film / dielectric barrier film through thermocompression bonding or adhesive. In this case, the dielectric pattern film 116 may be in contact with the dielectric barrier film 113. The pattern electrode 116 may be disposed to face the inside of the vacuum resin packaging container.

The valve 106 may be arranged to penetrate the dielectric pattern film 114, the dielectric barrier film 113, the ground electrode film 112, and the outer packaging film 111 in the pattern region. The valve 106 may be a check valve. The valve may be formed of a resin material and mounted and sealed in an opening formed in the vacuum resin packaging container (or the first packaging film). The valve (106) prevents external air from penetrating into the inside of the vacuum resin packaging container. On the other hand, the valve 106 is connected to a vacuum pump and an external plasma source through a connector 19. The connector includes a pusher 19a so that when the connector 19 is engaged with the valve, the valve 106 can be kept open at all times.

The valve 106 may be disposed in the pattern area and connected to an exhaust passage provided by the depression. Accordingly, when the vacuum resin packaging container is evacuated, efficient evacuation can be performed.

The dielectric barrier film 113 and the dielectric pattern film 214 are bonded to each other. The second packaging film is a resin film.

The dielectric barrier film 113 and the dielectric pattern film 214 are bonded to each other. The second packaging film is a resin film.

The dielectric pattern film 214 includes protruding portions connected to each other in a porous screen shape. And the pattern electrode 216 is formed on the protruding portion. In the vacuum state, the pattern electrodes 216 are electrically connected to each other and can discharge at an isolated depression, but can not provide a continuously connected exhaust passage for exhaust.

Thus, in order to provide an exhaust passage, the second packaging film 220 may be an embossing film having an island-shaped protruding portion 221 in an isolated island shape. The second packaging film 220 may provide an exhaust passage. In addition, when the first packaging film 210 performs the dielectric barrier discharge, the depression of the dielectric pattern film may provide a discharge space.
