Description

Vacuum Wrapping Plasma Sterilizer

The present invention relates to a vacuum package plasma sterilization apparatus for sterilizing a feature in a vacuum package, and more particularly, vacuum package plasma that can prevent the sterilant from leaking to the outside even when the vacuum package is exchanged using two vacuum pumps. It relates to a sterilization device.

Japanese Laid-Open Patent Publication (Japanese Patent Laid-Open No. 2008-183025) discloses a plasma sterilization apparatus by generating an atmospheric dielectric barrier discharge (DBD) using a breathable packaging material. Oxygen radicals generated directly by dielectric barrier discharges inside, ozone (O ₃ ) or hydroxyl groups generated by excitation of water vapor components in the atmosphere by ultraviolet rays (Ultra-Violet ray: UV-ray) emitted from the plasma ( Sterilization by OH-), hydrogen peroxide (H ₂ O ₂ ), or the like becomes possible. However, Japanese Patent Laid-Open No. 2008-183025 cannot discharge in a vacuum.

In addition, Korean Patent No. 10-1012442 discloses a sterilizing apparatus using atmospheric pressure plasma. However, the packaging material of Korean Patent No. 10-1012442 is not possible to secure electrical safety due to exposure to high voltage and generation of electromagnetic waves, and is not applicable as a device for sterilization as in Japanese Patent Application Laid-Open No. 2008-183025.

In the application of medical sterile packaging material, the existing packaging material only performs the basic function of preventing and storing secondary pollution of the sterilized medical device. In the sterilization of medical devices reusable in a medical institution, there are various medical packaging materials used for carrying out sterilization process using a medical sterilizer and then storing them. In order to prevent secondary contamination, a packaging material of a material having selective permeability to sterilizing agents defined in each sterilizer may be used to sterilize the medical device in the package after packaging. For example, a packaging material such as woven fabric, non-woven fabric, paper, or polypropylene may be used for the autoclave. In the case of an ethylene oxide (EtO) sterilizer, a packaging container made of polyethylene and Tyvek may be used as a polymer.

Medical sterilizers are required to achieve sterility of a medical device that performs a validated process, ie sterilization, to provide a medical device free of microorganisms. Representative medical sterilizers are autoclave sterilizers which perform sterilization at a high temperature of about 134 degrees Celsius and a high pressure of about 2 bar. There is a limitation that sterilization cannot be performed on medical devices which are limited to use in high temperature and high pressure processes such as food sterilization. In addition, since the steam sterilization is performed, additional restrictions occur due to corrosion of the medical device. Dry heat sterilizer to remove the limitation by moisture will be sterilized at a high temperature of about 180 degrees Celsius. However, there is a drawback that it is not applicable to medical devices including parts of a material such as plastic, which is susceptible to heat.

Recently, chemical sterilizers have been developed for sterilization of medical devices vulnerable to high temperature, high pressure and moisture, and ethylene oxide sterilizers are representative examples. However, due to the toxicity of ethylene oxide gas, proper management is necessary. After sterilization, it is required to be accurate for more than 8 hours. Recently, due to the danger of ethylene oxide gas, some countries regulate the use of ethylene oxide annihilator. . Plasma sterilizers have been developed and commercialized as environmentally friendly chemical sterilizers. However, chemical sterilizers can also have secondary contamination problems that may occur in the packaging process after sterilization.

To solve the secondary pollution problem, a special packaging film such as Tyvek was developed. However, the sterilization process of performing the medical device in a packaged state is bound to limit the permeability of the sterilant, and a long sterilization time of about 1 hour is required to secure the sterilization reliability.

In addition, the primary contamination of the packaging material may affect the permeability of the disinfectant, and has a problem that the sterilization reliability may be lowered. In addition, the conventional chemical sterilizer proceeds in the sterilization chamber and the size of the sterilizer is large, the introduction of the limited space due to lack of space in medical institutions, due to the expensive equipment is difficult to introduce technology.

Therefore, secondary pollution can be prevented through plasma sterilization in the packaging container, and there is no restriction on the permeability of the packaging material and thus may have high sterilization power.

According to an embodiment of the present invention, by sterilizing agents into a vacuum package or a vacuum package having a self sterilization capability, rather than the conventional sterilizer chamber, effective sterilization or sterilization may be performed. Accordingly, the space utilization is high, and the simplification of the equipment can be applied to economical and innovative sterilizer.

Conventional plasma sterilization apparatus places a workpiece in a fixed chamber, forms a plasma, and sterilizes it. In addition, in order to dry the workpiece, a heating means is arranged inside the fixed chamber. However, in the case of using the disposable vacuum wrapping paper instead of the fixed chamber as in the embodiment of the present invention, it is difficult for the heating means to be disposed inside the fixed chamber for the drying process. In addition, since the disposable vacuum wrapper is individually packaged for each object to be processed, when a new vacuum wrapper is replaced in the vacuum wrapper plasma sterilization apparatus, a high concentration of sterilant inside the vacuum wrapper plasma sterilizer may leak into the atmosphere, causing stability problems. . Therefore, there is a need for a new structure that solves the problem of stability of this drying process and sterilant leakage.

1 is a conceptual diagram of a plasma sterilization apparatus according to an embodiment of the present invention.

2 is a view showing the pressure of the vacuum wrapping paper of Figure 1 and the operating state of the valves.

1 and 2, the vacuum wrapper has a valve, such as a check valve, which can be connected to a vacuum pump or a plasma source. A plasma source and a vacuum pump are disposed to sterilize a workpiece stored in the vacuum wrapper. The first valve is arranged at the outlet of the plasma source, and the second valve is arranged at the inlet of the vacuum pump. The pipe connecting the outlet of the vacuum pump and the inlet of the plasma source has a branch and is connected to the atmosphere through a third valve.

At the end of the sterilization process of the previous vacuum wrapper, the first and second valves are closed and the previous vacuum wrapper is removed.

In order to evacuate the vacuum wrapper to which the new vacuum wrapper is connected, a first first closure and a second valve and a third valve are opened. However, in this case, the sterilant inside the vacuum pump leaks into the atmosphere through the third valve.

Initially opening the second and third valves to form a vacuum in the vacuum wrapper, the air inside the system is continuously discharged, the pressure of the system falls as a whole, and the second pressure P2 on the pressure graph decreases, It is difficult for the pressure P2 in each vacuum wrapping paper to remain constant.

In addition, the vented air contains a high concentration of sterilant remaining in the previous vacuum packaging sterilization process. Therefore, by the exhaust process, the user is constantly exposed to sterilizing agents, which present a risk factor.

The present invention was derived to solve this problem.

According to an embodiment of the present invention, while inserting a workpiece in a vacuum resin packaging container and evacuated to a vacuum, a dielectric discharge plasma is formed to provide sterilant, ultraviolet rays, and plasma to the workpiece. The treatment may be heated to form optimal sterilization process conditions. In addition, in a vacuum state, the external plasma source generates a plasma to provide a sterilant including hydrogen peroxide or nitrogen and oxygen active species (RONS) through a valve or connecting pipe of the vacuum resin packaging container. In addition, the processed material can be sterilized. The external plasma source produces large amounts of nitrogen and oxygen active species to sterilize the workpiece. In addition, in the state in which the vacuum resin container is evacuated to a vacuum, the pattern electrode integrated in the vacuum resin packaging container may secure a discharge space and an exhaust passage to form a dielectric discharge plasma to proceed with sterilization. In particular, the dielectric discharge plasma can sterilize the workpiece and heat the workpiece to a temperature for optimal sterilization process.

When the vacuum resin packaging container is evacuated using an external plasma source and a vacuum pump and a sterilant is supplied, the vacuum resin packaging container requires an embossing treatment on its surface for efficient evacuation.

According to one embodiment of the present invention, a dielectric pattern film is used which provides an exhaust passage while securing a discharge space in the packaging film.

Separate dielectric barrier discharges in vacuum resin packaging vessels produce nitrogen and oxygen active species at sub-atmospheric pressures to increase diffusion rates and reduce losses due to surface recombination of the sterilant to deep locations of the workpiece in the form of pipes. Sterilant can be delivered efficiently.

When the vacuum resin packaging container is under vacuum at atmospheric pressure, the dielectric barrier discharge is easy and occurs even at low power. Such internal discharge of the external plasma source and the vacuum resin packaging container itself can improve sterilization ability. In particular, it is suitable for the sterilization of medical devices requiring high sterilization ability. Complex sterilization by the external plasma source and the internal plasma source can significantly reduce the sterilization or sterilization process time, and does not require a separate cooling treatment as a pasteurization process. In addition, in the case of high temperature sterilization, it is possible to sterilize plastic medical devices that are not applicable due to thermal deformation. In addition, since a vacuum packaging container capable of generating plasma is used, a separate vacuum packaging process is unnecessary. Vacuum resin packaging container according to an embodiment of the present invention can save space compared to the high temperature autoclave, can reduce the sterilization time by efficient sterilization at low temperature, sterilization process is carried out at the same time vacuum packaging process and sterilization process Secondary pollution and cross-contamination are prevented, reducing the likelihood of a medical accident.

According to one embodiment of the present invention, a packaging film having a PET / AL / PE structure including a conventional aluminum foil film is used. The separate dielectric pattern film is formed of a resin film and includes a pattern region recessed or protruding on the surface thereof. The pattern electrode is selectively stacked on protruding portions connected to each other or recessed portions connected to each other in the pattern region. The PET / AL / PE structured packaging film and the dielectric pattern film may be laminated to each other 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 electrolytic plating or an electroless plating method.

However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided to ensure that the disclosed subject matter is thorough and complete, and that the spirit of the invention will be fully conveyed to those skilled in the art.

In addition, the first valve 21 and the second valve 22 are closed, and the third valve 23 and the fourth valve 24 are opened. Accordingly, since the vacuum wrapping paper 14 is exhausted by the second vacuum pump 33, the sterilant generated in the processing process of the previous vacuum wrapping paper is not discharged to the outside atmosphere. In addition, as the vacuum wrapping paper 14 is maintained at the first pressure, the workpiece is dried quickly.

Subsequently, the first valve 21 is opened to raise the vacuum wrapping paper 14 to a second pressure. Specifically, the first valve 21 is opened, and the second to fourth valves 22 to 24 are closed. Accordingly, the plasma source 31 produces a sterilant and supplies it to the vacuum wrapping paper 14, and the pressure of the vacuum wrapping paper 14 rises to a second pressure.

Subsequently, the first valve 21 is closed and the second valve 22 is opened to lower the pressure of the vacuum wrapping paper to the first pressure. Specifically, the second valve 22 opens and the first valve 21, the third valve 23, and the fourth valve 24 close. Accordingly, the first vacuum pump 31 lowers the pressure of the vacuum wrapping paper 14 to the first pressure.

Subsequently, maintaining the pressure at the first pressure for a period of time may be performed.

Then, increasing to the second pressure and decreasing to the first pressure can be repeated.
