Description

Medical Waste Sterilization System

[0001] The present invention relates to a system for collecting and sealing sterilizing packaging materials and collecting bins of medical waste generated in medical facilities such as health and medical institutions, veterinary hospitals, and testing and inspection institutions, in a controlled manner, pathogens that cause harm to the human body, and transporting the collected medical waste to a sterilizer and sterilizing the collected medical waste.

[0002] This system enables the recycling of medical waste by preventing secondary infection of workers and eliminating the source of infection through sterilization. It also provides advantages such as more reliable sterilization verification by making it easy to consistently manage microbial environmental variables through sterilization packaging.

[0003] Medical waste generated from healthcare facilities, such as health care institutions, veterinary hospitals, and testing and inspection organizations, carries a higher risk of infection than general waste, and must be handled safely. It is broadly divided into three categories: isolation medical waste generated from medical procedures on isolated individuals; hazardous medical waste generated from tissues, organs, cadavers, culture fluids, syringe needles, surgical instruments, spent vaccines, and blood; and general medical waste generated from cotton, bandages, gauze, disposable items, and diapers containing blood, body fluids, or excrement. These wastes may contain infectious substances and, if not properly handled, can pose a serious risk to public health.

[0004] Conventional medical waste disposal methods can be broadly categorized into two types: the problematic first-generation incineration method and the second-generation crushing and sterilization treatment method, which requires enormous installation costs and has low performance.

[0005] In the case of incineration, it is a method of reducing the volume and removing infectious substances by burning medical waste at high temperatures. During the incineration process, hazardous air pollutants such as dioxin, furan, fine dust, chemicals, and heavy metals may be released into the air. In addition, due to insufficient treatment capacity caused by an increase in medical waste, this can lead to remote incineration and illegal loading, high treatment costs, secondary infection problems, and public opposition. This causes environmental pollution and health risks, and it is a procedure that makes recycling of medical waste impossible at all due to complete combustion.

[0006] Pulverization sterilization is known as an alternative to incineration, but it is a method of killing pathogens in medical waste by pulverizing medical waste and then using steam, heat pipe, microwave sterilization, etc., and pulverizing is performed for effective sterilization, but the finely crushed debris remains in the chamber including the pulverizer blade, making hygienic treatment difficult. In addition, the raw materials of medical waste such as plastic, glass, and metal are mixed indiscriminately, showing low recycling performance. In addition, the lack of sterilization packaging and sealed collection boxes exposes workers to pathogens, which can lead to secondary infection problems. In addition, sterilizers, which are manufactured in a large size to meet facility regulations with a disposal capacity of more than 100 kg per hour, have enormous introduction costs and installation location problems, so their share of medical waste disposal methods is very low.

[0007] This leads to waste of resources and the loss of opportunities for environmental protection and resource conservation through recycling. Therefore, there is an urgent need to develop a safe, efficient, and sustainable medical waste disposal method that minimizes environmental pollution.

[0008] The present invention is to solve the above-mentioned problem, and is a system that can effectively process medical waste by collecting and sealing pathogens in medical waste that cause harm to the human body, such as infection, in a controlled manner using sterilizing packaging and a dedicated collection box, and transporting them to a sterilizer, and completely killing the pathogens using the sterilizer, thereby ensuring the safety of workers and recycling.

[0009] The sterilization packaging material is made of synthetic resin film and semi-permeable paper, and has an opening for collection and a receiving space. The semi-permeable paper allows the sterilizing agent to pass through, but completely blocks pathogens, so it has the effect of maintaining the sterilization period for a long time. In the case where a high-pressure steam sterilization method is adopted for the treatment of liquid medical waste, a heat conduction prevention band such as rubber can be provided at the opening of the packaging to prevent boiling over due to high temperature and pressure. In addition, a chemical indicator can be attached in the form of a sticker or printed on the packaging to identify whether sterilization has been completed through a pH mechanism color change, thereby ensuring the safety and reliability of the sterilization process, helping to reduce operator errors that may occur during the medical waste treatment process and reduce the risk of infection.

[0010] The structural design of the dedicated collection box is to use the sterilization packaging inside the collection box and combine the packing part to seal the internal and external environments, and the medical waste generated is collected and penetrated through the collection box trap, and at the same time, the trap is restored to its original state to close, blocking the air and preventing the outflow of pathogens, and one or more UV catalytic filters, UV lamps, and far-infrared rays are present to sterilize pathogens in the air and on the surface including the trap part that came into contact with the medical waste during the collection process, and when the medical waste collection is completed, the medical waste packaging is completely sealed by heat bonding automatically or manually, so that the pathogens are completely blocked and it can be transported to a medical waste sterilizer, thereby preventing infection of the workers handling it.

[0011] Medical waste sterilizers can be manufactured by adopting sterilization methods such as high-pressure steam, plasma, and microwave sterilization, and the sterilization packaging containing the collected medical waste is loaded into the sterilizer chamber loading section, and the appearance and QR code of the packaging are checked through a camera identification device to collect one or more pieces of information such as size, type, sterilization conditions, and weight, and the sterilization conditions are recommended and the sterilization conditions are confirmed from the worker, and sterilization proceeds. When sterilization is completed, the sterilization record, biological indicators, and chemical indicators are read to confirm whether sterilization has occurred, and the record can be printed and saved in the form of a report.

[0012] Sterilization validation requires a number of steps in physical and microbiological evaluations according to international standards, including a bioburden test that measures the degree of microbial contamination before sterilization to evaluate the appropriateness of the sterilization process, a sterility test that confirms that microorganisms are completely killed after sterilization, and various microbiological tests that utilize biological indicators for sterilization validation. Since sterilization packaging exists, it is possible to collect and store samples for microbial testing, and it is possible to derive accurate and reliable results by excluding external factors.

[0013] The goal is to provide a medical waste sterilization and treatment system that can follow the principles of source-source treatment and same-day treatment of medical waste, and that can safely collect, sterilize, and classify medical waste without unnecessary procedures through a simplified procedure, and that can be classified more easily and safely by material because the sterilized medical waste after the sterilization process has had pathogens removed, and that can maximize environmental protection and public health safety by promoting recycling and establishing a sustainable medical system through resource regeneration and resource circulation.

[0014] The present invention has been devised to solve the problem of narrow internal loading space for bulky medical devices, vials containing medicines that must be sterilized while standing upright, heavy laboratory supplies, etc., and the problem that the adhesive surface or packaging material cannot support products exceeding a certain weight. In addition, the pouch-type packaging material requires a sterilization packaging material larger than the product in order to contain a large product and join the four sides, and the problem of inevitably using excessive packaging material due to the narrow packaging material size even when multiple products are desired to be packaged at once. The purpose of the present invention is to provide a box-shaped sterilization packaging material to solve the problem of increased packaging cost due to complex problems and the absence of a suitable packaging material.

[0015] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0016] According to one embodiment of the present invention, in a medical waste sterilization packaging, the medical waste sterilization packaging includes a collection area in which one area is open, a side area surrounding the collection area, and a bottom area, and the sterilization packaging is made of a material that blocks the penetration of pathogens contained in the medical waste and selectively penetrates only a sterilizing agent used in the sterilization process, and the sterilization packaging is characterized in that it includes a sterilization identification portion that serves as at least one of a chemical indicator or a biological indicator for confirming the sterilization treatment of the medical waste.

[0017] It is characterized in that an overflow prevention band having low thermal conductivity is provided surrounding the side area to prevent liquid medical waste from boiling over due to at least one of high pressure and high temperature.

[0018] The medical waste collection box includes a housing that supports an internal configuration, and the housing includes an opening portion in which an area of ​​an upper surface is opened so that the medical waste is placed in the sterilizing packaging provided inside the housing; a cover provided so as to enable opening and closing of the opening portion; and a pedal provided to open the cover or a sensor for automatic opening and closing; and a sterilizing portion located on an inner upper surface of the housing to constantly sterilize and disinfect the opening portion and the inside of the housing and the entrance of the sterilizing packaging portion; and the opening portion is characterized in that it is provided to bind the sterilizing packaging portion and to pack and join it.

[0019] The above opening portion is opened in a square shape, and further includes an elastic opening / closing trap attached to each of the square edges of the opening portion to isolate the inside and outside space of the housing; the elastic opening / closing trap includes four square wing portions formed separately in a shape connecting the midpoint of each of the edges to the center point of the opening portion, and the square wing portions are characterized in that they are formed at a downward angle toward the center point of the opening portion.

[0020] The above medical waste sterilizer includes a loading section in which medical waste sterilization packaging is loaded, and identifies at least one piece of information among the shape, QR code, and weight of the medical waste based on a plurality of sensors provided in an area within the loading section to provide sterilization conditions, and monitors the sterilization process in real time and transmits it to the relevant authorities.

[0021] Medical waste is collected and sterilized using at least one of medical waste sterilization packaging, medical waste collection box, or medical waste sterilizer, and medical waste with pathogens killed is separated by material to enable recycling.

[0022] The present invention enables the sterilization packaging material for medical waste to block pathogens through differences in pore size and selectively allow the sterilizing agent used in the sterilization process to pass through, thereby maintaining sterilization effectiveness and a sterilized state, and by excluding external factors, enables the collection and storage of medical waste samples, thereby enabling reliable microbiological qualification evaluation and high-level guaranteed sterilization.

[0023] The above packaging is designed to accommodate large or heavy products, and is transparent, allowing for direct confirmation of the condition of medical waste inside. The change in chemical indicator color allows for easy visual identification of sterilization completion, helping to reduce the risk of operator error that may occur during the medical waste separation process through clear identification before and after the sterilization process.

[0024] The structural design of the medical waste collection box is designed to enable the effective placement and use of sterilized packaging, and the upper trap is present to collect through it, and the UV catalyst filter, far infrared rays, etc. are present to constantly sterilize pathogens in the air and the internal surface including the trap, thereby blocking and preventing transmission through infectious sources existing in medical waste, thereby preventing secondary infection, and the sterilization process is simplified, and the treatment process is simpler than the existing incineration and crushing treatment methods, providing the advantage of saving time and cost, and the principle of processing medical waste at the source on the same day it is generated can be maintained.

[0025] By classifying medical waste into each material after the sterilization process and reusing it, a sustainable medical waste disposal system is possible, contributing to environmental protection and enabling effective collection, sterilization, classification, and recycling of medical waste, thereby providing a medical waste sterilization disposal system that can promote environmental protection and public health safety.

[0026] In addition, the sterilizing packaging paper according to the present invention is manufactured in a hexahedron, so there is no unnecessary waste of packaging paper, and also, a product can be loaded through the opening and sealed with a single joint, and by being used by overlapping with a box, a wide loading space and durability are secured, making it easy to load large or heavy products.

[0040] Referring to FIGS. 1 to 9, a medical waste sterilization system according to one embodiment of the present invention includes a step of producing a sterilization packaging material (100) for sterilizing medical waste.

[0041] The production of a sterilizing packaging material (100) according to one embodiment of the present invention may begin with the selection of a material suitable for the sterilization process. This material must have the characteristics of blocking pathogens while selectively allowing the sterilizing agent to pass through. To this end, the sterilizing packaging material (100) is based on specially developed synthetic or natural materials, which are designed to react with the sterilizing agent to maximize the efficiency of the sterilization process.

[0042] Meanwhile, in the process of manufacturing the sterilizing packaging (100) according to the present invention, the sterilizing packaging (100) can be designed with ease of use in mind, and includes structural characteristics that enable it to be easily inserted into a medical waste collection box (200), safely wrap medical waste, and effectively sterilize it through a sterilization process, and the structure of the sterilizing packaging (100) is composed of an open top, a solid side area, and a sealable bottom area, which can be implemented to support effective distribution of the sterilizing agent during the sterilization process.

[0043] Meanwhile, medical waste according to one embodiment of the present invention refers to all forms of waste generated during medical activities or medical research. This includes used syringe needles, surgical gloves, bandages, cotton swabs, containers of chemicals used in laboratories, dead bodies of experimental animals, biological samples collected for diagnosis and their containers, etc., and such waste can be classified into infectious waste, chemical waste, radioactive waste, etc.

[0044] In addition, it goes without saying that the sterilizing packaging material (100) according to one embodiment of the present invention can be used not only for medical waste but also for medical supplies and medical devices that require sterilization.

[0045] Among the medical wastes according to the present invention, infectious waste refers to waste that contains pathogens and thus poses a risk of transmitting diseases to humans or animals, and thus must undergo a treatment process requiring special care and be safely disposed of through an appropriate sterilization or disinfection process. Chemical waste includes various chemicals, medicines, and their waste products used in laboratories, and these substances can have a harmful effect on the environment and therefore must be properly disposed of. Radioactive waste refers to waste containing radioactive substances generated during medical diagnosis or treatment, and thus requires special management and treatment. Meanwhile, for the convenience of explanation, the present invention will be described under the premise of treating infectious waste.

[0046] Medical waste circulation according to one embodiment of the present invention includes the entire process of collecting, classifying, processing, and, if possible, recycling waste generated from medical activities, in order to minimize the negative impact of medical waste on the environment and promote efficient use of resources, and the goal of medical waste circulation is to safely process medical waste and, at the same time, maximize the recovery of recyclable resources.

[0047] In general, the medical waste circulation process begins with waste collection at the initial stage.

[0048] This process involves classification by type of waste, sterilization or disinfection using various waste treatment methods, and finally, separation and reprocessing of recyclable resources. This process must be systematically managed both within and outside of medical institutions, and the methods and technologies applied at each stage may vary depending on the characteristics of the medical waste and relevant laws and regulations.

[0049] A medical waste sterilization system according to one embodiment of the present invention includes a step of selling a sterilization packaging material (100) for sterilizing medical waste.

[0050] The step of selling a sterilizing packaging material (100) according to one embodiment of the present invention involves supplying the sterilizing packaging material (100) to medical institutions, laboratories, and other facilities handling medical waste. The sales process of the sterilizing packaging material (100) includes establishing a marketing strategy and distribution channels, which are essential for effective market entry of the product.

[0051] The development of a sales strategy focuses on providing information that clearly communicates the characteristics and benefits of the sterilization packaging (100), enabling medical institutions to understand how the use of the sterilization packaging (100) can improve the efficiency and safety of medical waste disposal. Furthermore, the selection of distribution channels plays a crucial role in ensuring that the sterilization packaging (100) is readily accessible to target customers.

[0052] The primary objective of this step is to effectively supply the sterilizing packaging (100) to various facilities requiring medical waste disposal, thereby meeting the market demand for safe sterilization and disposal of medical waste, while at the same time promoting the commercial success of the present invention. The sales process may include a comprehensive approach ranging from product pricing, promotional activities, to customer service and support.

[0053] A medical waste sterilization processing system according to one embodiment of the present invention includes a step of collecting medical waste through a medical waste collection box (200) having a sterilization packaging material (100) provided therein.

[0054] The step of collecting medical waste according to one embodiment of the present invention uses a medical waste collection box (200) for effectively collecting medical waste generated in a medical institution or laboratory, and the medical waste collection box (200) according to the present invention has a sterilization packaging material (100) installed therein so that the collected medical waste can immediately undergo a sterilization process.

[0055] Meanwhile, the structure of the collection box according to the present invention is optimized according to the type and amount of medical waste, and can be designed considering the convenience and efficiency of the user. At this time, the sterilizing packaging material (100) is inserted inside the collection box to prevent the medical waste from being directly exposed to the environment during the collection process, and to minimize the risk of additional infection. In addition, the use of the sterilizing packaging material (100) enables the safe storage and transportation of medical waste, and provides a foundation for the sterilization process to be carried out more effectively in the subsequent stage.

[0056] That is, the process of collecting medical waste through a collection box begins by placing the collection box in an easily accessible location within a medical institution, and when medical waste is generated, the waste is immediately moved to a sterilized packaging material (100) within the collection box and collected, thereby ensuring safety and efficiency in the initial stage of medical waste disposal.

[0057] A medical waste sterilization system according to one embodiment of the present invention includes a step of identifying a sterilization packaging (100) containing medical waste and performing a sterilization process under preset sterilization conditions.

[0058] The step of performing a sterilization process according to one embodiment of the present invention first accurately identifies medical waste within a collected sterilization packaging (100), which can be accomplished through an identification function integrated into the sterilization packaging (100) or an external identification system linked to the sterilization packaging (100), and the information obtained through the identification process is used to determine the type, amount, and characteristics required for sterilization of the medical waste.

[0059] Next, based on the identified information, suitable sterilization conditions for the medical waste are determined. The sterilization conditions are set differently depending on the characteristics of the medical waste, and this is to maximize the effectiveness of the sterilization process. The sterilization conditions may include various variables such as temperature, time, type and concentration of sterilant, and ensure the safe sterilization of the medical waste to be processed together with the sterilization packaging (100).

[0060] The sterilization process begins according to the preset sterilization conditions, and this process is performed on medical waste together with the sterilization packaging (100). The sterilization process removes or inactivates pathogens and harmful microorganisms in the medical waste, thereby enabling safe treatment and recycling of the waste. After the sterilization process, the medical waste in the sterilization packaging (100) is converted into a state suitable for moving to a further treatment step. This step plays an important role in the medical waste sterilization treatment system, and improves the efficiency and safety of the overall waste management process.

[0061] A medical waste sterilization system according to one embodiment of the present invention includes a step of classifying medical waste that has undergone a sterilization process into each recyclable material.

[0062] The classification step according to one embodiment of the present invention classifies medical waste safely processed through sterilization into various materials, and the classification process is designed to recover recyclable resources contained in the medical waste to the greatest extent possible.

[0063] Sorting can be done through automated systems or manual processes, whereby various materials such as plastics, metals, and glass are identified and separated from each other. The sorted materials may undergo further processing before being moved to the recycling process, which is intended to increase the purity of the materials and improve recycling efficiency.

[0064] Medical waste classified as recyclable materials is then transported to a recycling plant and reprocessed into raw materials for new products, thereby promoting sustainable use of resources and contributing to environmental protection. By effectively recovering recyclable resources from medical waste, the environmental impact that may occur during the waste disposal process can be minimized, and economic value can be created through the reuse of resources.

[0065] More specifically, the sealing process according to one embodiment of the present invention ensures that collected medical waste is safely isolated inside the sterilization packaging (100), and ensures that the waste is not exposed to the external environment even after the sterilization process, and by sealing the upper part of the sterilization packaging (100), contributes to preventing additional contamination of medical waste, preventing leakage, and minimizing the risk of cross-contamination.

[0066] Meanwhile, the sealing process can be performed using tape, heat sealing, or other sealing techniques. For example, the heat sealing method is a method that can quickly and effectively seal the upper part of the sterilization packaging (100), and the sealing is performed under appropriate temperature and pressure conditions according to the characteristics of the material of the sterilization packaging (100). This sealing method allows the medical waste inside the sterilization packaging (100) to be completely isolated from the external environment, thereby increasing the efficiency of the sterilization process and enabling safe storage and transportation of the medical waste.

[0067] That is, sealing of the sterilization packaging material (100) according to the present invention is an important step in the process of collecting and processing medical waste, and is an essential measure for the hygienic and safe management of medical waste within a medical institution. Through this, the risk of infection that may occur during the handling of medical waste can be reduced, and environmental protection can also be contributed to during the waste processing process.

[0068] The step of performing a sterilization process according to one embodiment of the present invention includes the step of printing sterilization information including sterilization conditions including temperature, humidity, and pressure, sterilization date, and sterilization expiration date based on identification information attached to the sterilization packaging (100) and attaching the printed information to the sterilization packaging (100).

[0069] More specifically, the sterilization packaging (100) according to the present invention specifies important information after the sterilization process is completed, thereby ensuring the safety and traceability of sterilized medical waste, and the printing and attachment of sterilization information allows the sterilization status and expiration date of the sterilized medical waste to be clearly identified at all stages of handling the sterilized medical waste, thereby increasing the efficiency of infection control and waste management protocols in medical institutions.

[0070] Meanwhile, the printing and attachment process of sterilization information according to the present invention can be performed through an automated system, which accurately reads the identification information and prints information such as sterilization conditions, sterilization date, and sterilization expiration date on the sterilization packaging (100) in an appropriate format and size, and the printed information can be attached to the outside or inside of the sterilization packaging (100), and durable ink or labels such as waterproof and heat-resistant ink are used considering the material of the sterilization packaging (100) and the characteristics of the sterilization process.

[0071] Printing and attaching such sterilization information provides reliability during the subsequent handling of medical waste after sterilization within a medical institution, and serves as a medium for transmitting important information throughout the process of storing, transporting, and using medical waste under appropriate conditions. It can also contribute to improving infection control and patient safety in medical institutions through the safety management and quality control of medical waste.

[0072] A sterilizing packaging material (100) according to one embodiment of the present invention may be formed of a material that selectively allows only the sterilizing agent used in the sterilization process to pass through, among the pathogens contained in medical waste and the sterilizing agent used in the sterilization process. This sterilizing packaging material (100) is designed for the safe disposal of medical waste, and allows the sterilizing agent to effectively act on the medical waste during the sterilization process, while simultaneously preventing the external spread of pathogens.

[0073] The material of the sterilizing packaging paper (100) according to the present invention is implemented with a special material that prevents the penetration of pathogens and enables selective penetration of the sterilizing agent. This allows the sterilizing packaging paper (100) to act as an intermediate medium between medical waste and the sterilizing agent, while allowing the sterilizing agent to directly contact only the medical waste within the packaging paper. This selective penetration can be achieved by advanced material technology and manufacturing processes applied to the sterilizing packaging paper (100).

[0074] In a specific embodiment, the sterilization packaging material (100) can be manufactured from a material having a multi-layer structure, each layer being specialized to block pathogens, allow effective penetration of the sterilant, and provide physical strength. For example, the inner layer is composed of a highly permeable material to allow the sterilant to directly access the medical waste, and the outer layer is manufactured from an impermeable material to prevent the spread of pathogens. The sterilant used in the sterilization process may be various, such as steam, chlorine dioxide, or ethylene oxide, and the material of the sterilization packaging material (100) provides optimized permeability for such sterilant.

[0075] The sterilization packaging material according to the present invention may be comprised of semi-permeable paper that blocks pathogens but selectively allows sterilizing agents to pass through, and a thermoplastic film for sealing. The dual-structure design of this sterilization packaging protects the medical waste collected inside from external infectious agents, while simultaneously allowing the sterilizing agent used during the sterilization process to effectively access and sterilize the medical waste.

[0076] Semi-permeable paper has the property of blocking the penetration of air and fine particles while allowing the penetration of specific chemical substances, such as sterilizing agents, so that the medical waste inside the sterilizing packaging is isolated from the external environment while supporting the effective sterilization process, and is particularly effective in blocking the penetration of infectious substances such as pathogens. In addition, thermoplastic films are used at the top or joints of sterilizing packaging to seal the sterilizing packaging and maintain a sealed state even after the sterilization process. These films melt when heated and strongly adhere to other materials, blocking the inflow of contaminants from the outside and effectively preserving the sterilized state.

[0077] The material composition of such sterilization packaging serves as an important factor for the safe collection, storage, and sterilization of medical waste, and contributes to significantly improving the efficiency of infection control and waste disposal in medical institutions. Furthermore, such sterilization packaging can be used not only in medical institutions but also in various environments such as laboratories, and plays an essential role in the safe disposal of all types of waste that pose a risk of infection.

[0078] A sterilizing packaging material (100) according to one embodiment of the present invention includes an open area in which one area is open, a side area surrounding the open area, and a bottom area sealably connected to the side area, and a sterilization identification section that serves as at least one of a chemical indicator or a biological indicator for confirming the sterilization of medical waste may be included in a portion of the side area. Here, the biological indicator may include an indicator such as the amount of residual microorganisms such as pathogens or bacteria.

[0079] The structure of the sterilization packaging (100) according to one embodiment of the present invention facilitates the collection and sterilization process of medical waste, and allows the sterilizing agent to effectively act within the waste during the sterilization process. Furthermore, the sterilization identification portion located on a portion of the side area acts as a chemical indicator that reacts with the sterilizing agent to notify the user of the completion of the sterilization process through a color change or other visual change.

[0080] In a specific embodiment, the sterilization packaging (100) can be manufactured in various sizes to accommodate medical waste of various sizes and shapes. The open area is designed to be large enough to allow a user to easily place medical waste inside the packaging, and the side area and the bottom area are strong and durable so that the medical waste can be stably stored inside the sterilization packaging (100). The sterilization identification portion has sensitivity to a specific sterilizing agent and enables confirmation that the sterilization process has been performed under appropriate conditions. For example, in the case of packaging for an ethylene oxide sterilization process, the sterilization identification portion can be treated with a special ink that changes color in the presence of ethylene oxide, allowing a user to easily identify it at the time of completion of the sterilization process.

[0081] The design of this sterilization packaging (100) optimizes the safe collection, storage, sterilization and final disposal processes of medical waste, thereby increasing the efficiency of waste management in medical institutions and contributing to improving the safety and reliability of the sterilization process.

[0082] According to one embodiment of the present invention, a sterilizing packaging material may be provided with a low thermal conductivity overflow prevention band surrounding a side area to prevent liquid medical waste from boiling over due to at least one of high pressure and high temperature.

[0083] An overflow prevention band according to one embodiment of the present invention is designed to wrap around the side of a sterilization packaging paper, and prevents liquid medical waste from overflowing out of the packaging paper in a high temperature or high pressure situation that may occur during a sterilization process.

[0084] That is, the material of the overflow prevention belt has low thermal conductivity, so it effectively suppresses the boiling of the liquid inside the packaging by preventing the internal temperature rise from being quickly transferred to the outside, and in particular, it acts as an insulator against heat that may be generated by high-temperature steam or other heat treatment methods used during the sterilization process, helping to maintain the pressure inside the packaging at a safe level.

[0085] The application of these anti-overflow strips is particularly important when sterilization packaging contains liquid medical waste, as they control the movement of liquid that may occur during the sterilization process, preventing leakage to the outside and ensuring the safety of the packaging and its contents. The anti-overflow strips also improve the structural stability of sterilization packaging and contribute to minimizing environmental and health risks that may arise during the medical waste disposal process. These characteristics make the medical waste disposal process safer and more efficient, playing a significant role in infection control and improving environmental safety in medical institutions.

[0086] In a medical waste sterilization processing system according to one embodiment of the present invention, medical waste is collected and sealed through a sterilization packaging paper and a collection box, loaded into a medical waste sterilizer for sterilization, and a step of confirming the appearance of the packaging paper and a QR code by camera identification to collect at least one piece of information among size, type, sterilization conditions, and weight, recommending sterilization conditions, and confirming the sterilization conditions from a worker is included, and through this, a record of the sterilization process can be left and provided so that it can be printed and read.

[0087] More specifically, a medical waste sterilization processing system according to one embodiment of the present invention includes a process of collecting and sealing medical waste using a sterilization packaging material and a collection box. In this step, after medical waste is loaded into a sterilizer for sterilization, a camera is used to identify the appearance of the packaging material and a QR code, and through the identification process, at least one piece of information among the size, type, sterilization conditions, and weight of the medical waste is collected, and sterilization conditions are recommended based on this. The recommended sterilization conditions are confirmed by a worker, and this process ensures the efficiency of the sterilization process and minimizes errors.

[0088] This ensures that every step of the sterilization process is recorded, output, and legible. This reduces human error during the sterilization process, improves the accuracy and traceability of sterilization processes, and the automated data collection and processing of the sterilization processing system simplifies the oversight and management of the sterilization process, supporting regulatory compliance required by healthcare institutions.

[0089] In particular, the data identification and recommendation system using the QR code on the sterilization packaging accurately identifies the type of medical waste and the corresponding appropriate sterilization requirements, thereby contributing to optimizing the operating efficiency of the sterilizer and reducing energy consumption. This technological approach provides an effective way to reduce the cost of medical waste disposal, minimize environmental impact, and improve the working environment of medical institutions.

[0090] The material of the sterilization packaging according to the present invention may be a film or semi-permeable paper formed of one or more synthetic resins selected from the group consisting of LDPE (Low Density Polyethylene), HDPE (High Density Polyethylene), PP (Polypropylene), PVC (Polyvinyl Chloride), and PS (Polystyrene).

[0091] The above semi-permeable paper is medical paper, and may include medical Tyvek made of HDPE or medical paper made of pulp. The above semi-permeable paper functions as a sterilization window, allowing sterilization gas or beams to pass through but blocking microorganisms such as bacteria. In particular, it functions as a filter to prevent the penetration of bacteria, thereby preventing the penetration of bacteria during the expiration date after sterilization.

[0092] Preferably, the sterilization packaging material is formed of a composite film, and excellent visibility can be secured by combining a semi-permeable paper (140) on one side of the composite film. The composite film preferably includes a film formed of at least one synthetic resin selected from the group consisting of LDPE (Low Density Polyethylene), HDPE (High Density Polyethylene), PP (Polypropylene), PVC (Polyvinyl Chloride), and PS (Polystyrene); and a coating layer coated on the film.

[0093] The above coating layer is preferably formed of a composition for forming a coating layer including 58-62 parts by weight of an acrylic polymer resin, 8-12 parts by weight of an acrylonitrile butadiene styrene resin (ABS resin), 3-7 parts by weight of a urethane additive, 8-12 parts by weight of calcium carbonate, 1-5 parts by weight of 2-ethylhexyl methacrylate, 1-5 parts by weight of dimethacrylate diethylene glycol, 1-5 parts by weight of pentaerythrol-tris-(beta-(N-aziridinyl)propionate, 0.8-1.2 parts by weight of an azobisisobutyronitrile initiator, and 3-7 parts by weight of 2-(perfluorobutyl)ethyl triethoxysilane, and 59-61 parts by weight of an acrylic polymer resin, 9-11 parts by weight of an acrylonitrile butadiene styrene resin (ABS resin), It is more preferable that the coating layer be formed of a composition for forming a coating layer comprising 4-6 parts by weight of a urethane-based additive, 9-11 parts by weight of calcium carbonate, 2-4 parts by weight of 2-ethylhexyl methacrylate, 2-4 parts by weight of diethylene glycol dimethacrylate, 2-4 parts by weight of pentaerythrol-tris-(beta-(N-aziridinyl)propionate, 0.9-1.1 parts by weight of an azobisisobutyronitrile initiator, and 4-6 parts by weight of 2-(perfluorobutyl)ethyl triethoxysilane.

[0094] It is preferable that the above acrylic polymer resin contains 23-27 parts by weight of methyl methacrylate monomer units, 23-27 parts by weight of 2-ethylhexyl acrylate monomer units, 23-27 parts by weight of 2-ethoxyethyl methacrylate monomer units, and 23-27 parts by weight of 2-phosphonooxyethyl methacrylate (2-(phosphonooxy)ethyl methacrylate) monomer units. By applying the above acrylic polymer resin as the main resin, not only excellent durability but also heat resistance can be secured.

[0095] The above ABS resin is applied as an auxiliary resin to improve scratch resistance.

[0096] The above urethane-based additive is manufactured by mixing polytetramethylene glycol (PTMG), dimethylol propionic acid, N-methylpyrrolidone (NMP) solution, and isophorone diisocyanate to prepare a prepolymer, neutralizing the prepolymer with triethylamine diluted in N-methylpyrrolidone (NMP) solution, adding distilled water to the neutralized prepolymer to disperse it in water, adding ethylene diamine as a chain extender to prepare a polyurethane, and adding ethylmetaacrylate and azobisisobutyronitrile (AIBN) to the polyurethane and stirring. The above urethane-based additive is applied to secure excellent durability and scratch resistance, thereby helping to protect the product.

[0097] The above calcium carbonate is applied as a filler to improve durability.

[0098] By applying the above 2-ethylhexyl methacrylate, dimethacrylate diethylene glycol, pentaerythritol-tris-(beta-(N-aziridinyl)propionate and 2-(perfluorobutyl)ethyl triethoxysilane, the adhesion to the film is increased, thereby improving durability.

[0099] In addition, the sterilizing packaging paper according to the present invention may include an inner partition (300), a bottom buffer (400), and a side buffer (500) formed in the receiving space of the sterilizing packaging paper, as shown in Fig. 8. This may be applied to accommodate products such as heavy products, bulky products, fragile products, sharp medical devices, and medical waste, and to protect the products and the packaging paper itself. The buffer may be made of paper, plastic, sponge, foam, or the like.

[0100] In addition, referring to FIG. 9, when the sterilizing packaging according to the present invention is not in use, the sterilizing packaging and the outer box (B) can be combined and then unfolded into a hexahedral box shape for storage in a thin form. Accordingly, portability is maximized, and when necessary, it can be folded into a box shape for use.

[0101] In addition, the present invention includes a sterile packaging material having a hexahedron shape, including an open portion at the top and a product receiving space inside, an outer box (B) for receiving the sterile packaging material, and a towing box (C) for receiving the outer box (B) and having a handle formed therein.

[0102] As shown in Fig. 10, it includes an outer box (B) for accommodating a sterilizing packaging material and a towing box (C) for accommodating the outer box (B) and having a handle formed thereon, and the towing box includes handles (H1, H2) and a bottom surface (H3). The towing box may be formed of a material such as plastic or metal.

[0103] The above sterilized packaging material is first packed in an outer box (B) and then placed in a tow box (C) for transport.

[0104] A medical waste collection box (200) according to one embodiment of the present invention is used for the purpose of collecting and temporarily storing medical waste, and supports the safe collection and processing of medical waste together with a sterilized packaging material (100). The collection box according to the present invention is placed and used in various locations within a medical institution, and provides the convenience of being able to immediately collect waste generated during medical activities. It can be provided in various shapes and sizes depending on the type of waste, such as infectious waste or non-infectious waste, and has characteristics for processing appropriately for the type of waste.

[0105] The collection box according to the present invention is designed to ensure user convenience, safe storage of waste, and smooth movement to subsequent processing. To this end, the collection box is constructed of a robust material for durability and has a sealable structure to minimize the risk of infection. Furthermore, the design facilitates the insertion and replacement of the sterilization packaging (100). If necessary, the collection box may also include features to facilitate the identification and classification of waste that has passed the sterilization process.

[0106] A medical waste collection box (200) according to one embodiment of the present invention includes a housing that supports an internal configuration.

[0107] According to one embodiment of the present invention, the housing forms the outer structure of the collection box and serves to stably support and protect the medical waste collection-related components, including the sterilization packaging (100), within. The housing is made of a robust material to protect the contents from physical damage and ensure the durability of the collection box. Furthermore, it can be made of a material that is easy to clean and disinfect depending on the usage environment, thereby contributing to minimizing the risk of infection.

[0108] In specific embodiments, the housing may be made of various materials such as plastic, metal, or a combination thereof. For example, a plastic housing may be lightweight yet provide sufficient strength, which may be advantageous in terms of portability and ease of use, while a metal housing may provide greater durability and sturdiness, and may be fire-resistant and suitable for long-term use. In addition, the design of the housing may include a lid that can be easily opened and closed, a movable design with wheels, or a structure for easy replacement of the inner sterilization packaging (100) taking into account the convenience of the user.

[0109] According to one embodiment of the present invention, a housing includes an opening in which an area of ​​an upper surface is opened so that medical waste can be placed in a sterilizing packaging (100) provided inside the housing.

[0110] The opening according to one embodiment of the present invention performs the important function of allowing the user to easily insert medical waste into the collection container, and is designed to make the medical waste collection process efficient and hygienic. The design of the opening is designed with consideration for user convenience and safety, as well as protecting the sterilizing packaging (100) inside the collection container from contamination.

[0111] In a specific embodiment, the opening according to one embodiment of the present invention can be designed in various shapes and sizes depending on the purpose of use and environment of the collection box. For example, in the case of a collection box used in a medical institution, the opening can be of sufficient size and finished with a lid that can be operated with a handle or pedal so that a user can easily put in medical waste, which allows the user to put in waste without touching the opening, thereby reducing the risk of cross-contamination.

[0112] In another example, facilities handling high-risk medical waste can design their openings to be automatically activated by sensors, automatically opening when a user places their hand near the opening and automatically closing after the waste is deposited. Such automated openings minimize direct contact between the user and the collection container, providing a more hygienic waste collection environment.

[0113] The design of the opening can be customized to reflect the type of medical waste, user convenience, and the specific needs of the healthcare environment. The easy loading and safe storage of medical waste through the opening contributes to the efficiency and safety of medical waste management.

[0114] Additionally, the opening portion according to the present invention may be configured to bind the sterilizing packaging and perform packing bonding and joining. This allows the sterilizing packaging to be inserted through the opening portion and subsequently sealed, ensuring that the contents of the sterilizing packaging are completely isolated from the external environment. The opening portion includes a packing bonding mechanism, which functions to securely seal and seal the top of the sterilizing packaging.

[0115] These binding and packing bonding functions allow for the quick and effective sealing of the opening of the sterile packaging when it is inserted with medical waste, and are particularly important for the safe disposal of medical waste through the sterilization process, and play a key role in maintaining the sterile condition inside the packaging.

[0116] The sealing mechanism of the opening provides double protection, preventing contaminants from leaking out from inside the packaging and preventing external contaminants from entering. This reduces the risk of infection when used in medical institutions and contributes to the reliability of the sterilization process. Furthermore, this sealing function enables the safe transport and storage of medical waste, improving the efficiency and safety of overall medical waste management.

[0117] Additionally, the opening's sealing mechanism physically seals the open portion of the sterilization packaging using thermal bonding, adhesives, or mechanical clips. This sealing process is automated, so the sealing process begins immediately after insertion of the packaging, which is essential for maintaining the safety and sterility of the contents. The packaging is also sealed under specific pressure and temperature conditions, ensuring a secure seal. This process ensures that the contents do not leak out, even if the internal pressure of the packaging fluctuates during the sterilization process.

[0118] A housing according to one embodiment of the present invention includes a cover provided to enable opening and closing of an opening portion.

[0119] A cover according to one embodiment of the present invention safely covers the opening of a medical waste collection box (200), so that the sterilization packaging (100) and waste inside can be protected from the external environment. The cover is designed so that the user can easily open and close it during the process of putting in waste, and at the same time protects the inside of the collection box from external contamination.

[0120] In specific embodiments, the cover can be operated through various mechanisms such as a pedal, a handle, a sensor, etc. For example, a method in which the cover opens when a user presses a pedal with his / her foot allows the user to insert waste without using his / her hands, which is particularly useful in reducing the risk of cross-contamination in environments handling infectious waste. In another embodiment, the cover can be implemented as an automated cover system that allows the user to manually open and close the cover, or automatically opens and closes the cover using a motion sensor or infrared sensor to increase accessibility, thereby enabling hygienic waste management because the user does not have to directly contact the cover or the collection box.

[0121] Meanwhile, the material of the cover according to the present invention may be various materials such as metal, plastic, or a combination of the two, and may be customized to suit the specific requirements and environment of the medical institution.

[0122] According to one embodiment of the present invention, a housing includes a position fixing member that is fixedly connected to the inner central surface of the housing so that a side area of ​​a sterilizing packaging material (100) is maintained in an unfolded state.

[0123] According to one embodiment of the present invention, a position fixing unit is provided so that the sterilizing packaging (100) can maintain an appropriate position and shape inside the collection box, so that the side area of ​​the sterilizing packaging (100) is fixed at an appropriate position, thereby supporting more efficient input of waste and sterilization processes.

[0124] In a specific embodiment, the position fixing unit may be implemented in the form of a clip, a latch, or a rail system mounted inside the housing. For example, a clip-shaped position fixing unit can easily fit and fix the side area of ​​the sterilizing packaging (100), and provides flexibility for the user to easily release and re-fix it when replacing the sterilizing packaging (100). A position fixing unit using a rail system can fix the side area of ​​the sterilizing packaging (100) by sliding it along the rail, thereby enabling more stable fixation and making it easy to adjust the position of the sterilizing packaging (100).

[0125] The design of this position fixing device allows the sterilizing packaging material (100) to maintain an optimal position within the collection box, thereby increasing the efficiency of the sterilization process and ensuring that medical waste is safely stored, isolated from the external environment.

[0126] According to one embodiment of the present invention, a housing includes a packaging stand that is positioned on the inner lower surface of the housing to maintain the bottom area of ​​the sterilizing packaging (100) in an unfolded state and to support the bottom area.

[0127] According to one embodiment of the present invention, the packaging stand-up section supports the bottom area of ​​the sterilizing packaging (100) so that the sterilizing packaging (100) can have a stable foundation inside the collection box and maintain its shape even during the input and sterilization process of medical waste, thereby allowing the packaging to maintain an appropriate shape and medical waste to be collected effectively.

[0128] In a specific embodiment, the packaging stand according to the present invention may be in the form of a frame made of, for example, plastic or metal, and may provide sufficient strength to effectively support the bottom area of ​​the sterilizing packaging paper (100) and maintain the unfolded state. In addition, the packaging stand may have an adjustable structure so that it may be flexibly applied to sterilizing packaging paper (100) of various sizes, and may be designed so that the user can easily adjust it as needed.

[0129] The application of the packaging stand allows the sterilizing packaging (100) to maintain an optimal position and shape within the medical waste collection box (200), thereby increasing the efficiency of the sterilization process and ensuring safe collection and storage of medical waste. Through this, medical institutions can improve the reliability and safety of medical waste management and minimize the risk of infection that may occur during the process of handling medical waste.

[0130] According to one embodiment of the present invention, a housing includes a sterilizing unit located on the inner upper surface of the housing to constantly sterilize and disinfect the inlet of a sterilizing packaging material (100).

[0131] A sterilizing unit according to one embodiment of the present invention continuously sterilizes the entrance portion of a sterilizing packaging paper and the surrounding area using an ultraviolet (UV) light source, thereby preventing the inflow of contaminants during the process of introducing medical waste, maintaining the internal environment of the sterilizing packaging paper (100) hygienic, and contributing to reducing the risk of infection, especially when handling infectious medical waste.

[0132] In a specific embodiment, the sterilizing unit may include a UV lamp or LED installed on the upper surface inside the housing, thereby emitting UV rays of a specific wavelength to effectively sterilize microorganisms that may exist in the air passing through the inlet of the sterilizing packaging (100) and on the surface of waste. UV sterilization technology has a high sterilizing effect on a wide range of microorganisms, and has the advantage of enabling safe and effective sterilization without the use of chemical disinfectants.

[0133] The design of the sterilization unit is designed to optimize the position, intensity, and irradiation time of the UV light source to effectively sterilize the entrance and internal space of the sterilization packaging (100). Furthermore, depending on the usage environment, the UV sterilization unit can operate in automatic or manual mode, and may also include a function that allows the user to control the sterilization process as needed.

[0134] That is, the introduction of a medical waste collection box (200) including a sterilizing unit according to the present invention can be implemented to effectively manage infection control and hygiene maintenance in a waste management system of a medical institution, thereby effectively managing the risk of infection that may occur during the process of collecting, storing, and processing medical waste.

[0135] According to one embodiment of the present invention, a housing includes a pedal configured to open a cover. The pedal according to the present invention refers to a functional component that allows a user to easily open the housing cover with their feet without using their hands. The purpose of using the pedal is to reduce the risk of infection and maintain a hygienic environment by eliminating the need for the user to directly touch the cover when disposing of medical waste.

[0136] In a specific embodiment, the pedal is positioned near the bottom of the housing, and when the user steps on the pedal, the cover automatically opens through a mechanism, wherein the mechanism may be designed to include a lever, a spring, and a hinge, which convert the pressure of the pedal into an opening motion of the cover, thereby maximizing the user's convenience and ensuring efficient transmission of force, so that the cover can be easily opened with minimal effort.

[0137] Meanwhile, the cover according to the present invention can be implemented to automatically open and close using a sensor for automatic opening and closing. This sensor detects the open / closed state of the cover and automatically operates the cover accordingly. This allows the user to conveniently place medical waste in the collection bin without having to manually open and close it, thereby contributing to reducing the risk of cross-contamination. The sensor function controls the opening and closing of the cover using electrical signals, and, if necessary, detects the user's approach and automatically opens or closes the cover. This automatic opening / closing function plays a crucial role in increasing efficiency and strengthening the stability of medical waste management, particularly within medical facilities.

[0138] According to one embodiment of the present invention, the opening portion is opened in a square shape and further includes an elastic opening / closing trap attached to each edge forming the square of the opening portion to isolate the inside and outside space of the housing.

[0139] The elastically openable trap according to the present invention allows opening when necessary, such as when medical waste is to be placed through the opening, and automatically closes after the waste is placed, thereby isolating the internal environment of the housing from the outside. This configuration facilitates the hygienic use of the medical waste collection box (200) and protects the internal sterilization packaging (100) and collected medical waste from external contamination.

[0140] In a specific embodiment, the elastically closed trap is made of silicone, rubber, or other flexible material. It easily deforms and opens when a user inserts medical waste, and automatically closes the opening by returning to its original shape after the waste is inserted. The elastically closed trap may also be designed to be evenly distributed around the rectangular opening, facilitating the insertion of medical waste from all directions while maintaining a perfect seal.

[0141] Meanwhile, the elastic opening / closing trap according to the present invention reduces the risk of infection that may occur during use of the medical waste collection box (200). For example, even when additional medical waste is added, the elastic opening / closing trap quickly and effectively closes the opening, isolating the interior of the housing from the external environment. This characteristic contributes to creating an environment for the safe collection, storage, and processing of medical waste within medical institutions.

[0142] An elastic opening / closing trap according to one embodiment of the present invention includes four square wing portions formed separately from the center point of the opening portion to the midpoint of each edge, and the square wing portions may be formed to form a downward angle toward the center point of the opening portion.

[0143] According to one embodiment of the present invention, the square wing section enables easy insertion of waste when opened so that waste can be efficiently opened and closed when being inserted or removed through the opening of the medical waste collection box (200), and effectively isolates the internal and external spaces through a mechanism that automatically closes after the waste is inserted.

[0144] In a specific embodiment, the square wing portion is made of a flexible material, so that it can be easily opened by a slight pressure when medical waste is fed in, and when the feeding is completed, it automatically returns to its original state by elastic force to seal the opening portion. The downward slope guides the medical waste to easily move toward the center point, thereby providing smooth feeding of the waste and efficient guidance into the collection box. The design of the square wing portion can be varied, particularly depending on the type and size of the medical waste, and can be customized to exhibit optimized performance for the waste being fed.

[0145] The application of an elastic opening / closing trap including such a square wing greatly improves the usability of the medical waste collection box (200), effectively blocks the inflow of contaminants that may occur during use into the housing, and also ensures sanitary and safe collection and processing of medical waste within a medical institution.

[0146] Meanwhile, the sterilizing unit according to one embodiment of the present invention can be controlled to sterilize the upper part of the sterilizing packaging material (100) in a preset first cycle depending on the environment in which it is used.

[0147] More specifically, the sterilization unit according to the present invention regularly sterilizes the upper part of the sterilization packaging (100) and the collected medical waste, thereby continuously maintaining the open part and the internal space of the sterilization packaging (100) in a sanitary state. The UV sterilization process maintains a sterilized state by effectively removing pathogens that may exist in the air or on the surface without direct contact with the sterilization packaging (100).

[0148] In a specific embodiment, the sterilization unit is controlled by a timer or sensor and is automatically activated at set time intervals (e.g., hourly or daily at a set time) according to the characteristics of the usage environment. For example, in an environment requiring a high level of infection prevention, such as an intensive care unit of a medical institution, the sterilization unit can be set to a shorter cycle to perform the sterilization process frequently, and the sterilization unit uses a high-power UV lamp or LED to effectively kill microorganisms at the top and entrance of the sterilization packaging (100) within a short period of time.

[0149] The effect of this UV sterilization process prevents further contamination of medical waste and contributes to continuously maintaining a sterile state inside the sterilization packaging (100), which helps improve overall infection control and patient safety in medical institutions in safely collecting and processing medical waste within the medical institution, and also, continuous sterilization management through the UV sterilization process can improve the usability of the medical waste collection box (200) and minimize the risk of infection associated with medical waste.

[0150] A medical waste sterilization processing system according to one embodiment of the present invention includes various components such as a sterilization packaging material, a medical waste collection box, and a medical waste sterilizer for safely and efficiently processing medical waste, and each component supports the collection, sterilization, classification, and recycling processes of medical waste.

[0151] First, a medical waste sterilizer according to one embodiment of the present invention includes a loading section in which medical waste sterilization packaging is loaded. Multiple sensors are provided within the loading section to identify at least one piece of information, including the shape, QR code, and weight of the medical waste. These sensors scan the QR code attached to the sterilization packaging to identify the type and characteristics of the medical waste. A shape recognition sensor detects the size and shape of the medical waste, and a weight measurement sensor measures the weight of the medical waste. Based on this information, the system provides sterilization conditions and includes a function to monitor the sterilization process in real time and transmit it to the relevant authorities. This system ensures the accuracy and reliability of the sterilization process and supports the safe disposal of medical waste.

[0152] In a specific embodiment, a medical waste sterilizer analyzes sensor data collected through a central processing unit and sets optimal conditions for the sterilization process. For example, it automatically determines the appropriate temperature, pressure, and time conditions for a specific type of medical waste and performs the sterilization process based on these conditions. Upon completion of the sterilization process, the central processing unit transmits the sterilization results to relevant authorities in real time, ensuring regulatory compliance. This automated system streamlines the medical waste sterilization process and maximizes efficiency.

[0153] In addition, a medical waste sterilization processing system according to one embodiment of the present invention collects and sterilizes medical waste using at least one of a sterilization packaging material, a medical waste collection box, and a medical waste sterilizer. After the sterilization process is completed, the medical waste, from which pathogens have been killed, is separated by material to enable reuse. To this end, the sterilization packaging material is manufactured from a material that blocks the penetration of pathogens while allowing the sterilizing agent to pass through, and is designed to safely store the medical waste even after the sterilization process.

[0154] In a specific example, medical waste that has undergone the sterilization process is separated into various materials, such as plastic, glass, and metal, through an automatic sorting system. These separated materials undergo a separate recycling process and are reused as raw materials for new products. For example, sterilized plastic medical waste is washed, crushed, and reprocessed at a recycling plant to become new plastic products. This recycling process promotes efficient use of resources and contributes to environmental protection.

[0155] That is, the medical waste sterilization treatment system according to the present invention plays an important role in increasing the sustainability of the medical environment, reducing medical waste treatment costs, minimizing environmental impact, and safely treating and recycling various types of medical waste generated in medical facilities such as hospitals through safe collection, sterilization, classification, and recycling of medical waste.

[0156] The preset first cycle according to one embodiment of the present invention can be derived based on the following [Mathematical Formula 1].

[0157]

[0158] [Mathematical Formula 1]

[0159] In the above [Mathematical Formula 1], T represents the first cycle (sec), A represents the average pathogen density (CFU / cm2) within the housing, where CFU stands for Colony Forming Units. B represents the average relative humidity (%) of the usage environment, C represents the maximum output (W, watt) of the UV light source, D represents the average distance (cm) between the sterilizing packaging (100) and the UV light source, E represents the average temperature (℃) of the usage environment, and e represents a natural constant.

[0160] More specifically, in [Mathematical Formula 1], as the average pathogen density within the housing increases, the first cycle increases, which reflects that a longer operating interval is required to effectively sterilize a higher pathogen density; as the humidity increases and the output of the UV light source increases, more time is required to maximize the sterilization effect; as the distance between the sterilization packaging (100) and the UV light source increases, the first cycle tends to decrease, which reflects that the sterilization process must be performed more frequently because the intensity of the UV light weakens as the distance increases, thereby reducing the sterilization effect; and as the average temperature of the usage environment increases, the first cycle decreases, which reflects that more frequent sterilization is required because the growth rate of pathogens may increase at high temperatures.

[0161] Meanwhile, the logarithmic function in [Mathematical Formula 1] controls the influence of the sterilization cycle according to the pathogen density by ensuring that the sterilization cycle does not increase exponentially as the pathogen density increases, but shows a linear increase pattern, and the exponential function considering the average relative humidity (B) of the use environment, the maximum output (C) of the UV light source, and the average distance (D) between the sterilization packaging material (100) and the UV light source models the complex influence of humidity and the output of the UV light source on the sterilization effect. As the relative humidity increases, the physical and chemical reaction rates may generally change, and although the output of the UV light source plays an important role in the sterilization effect, its efficiency varies depending on the distance from the light source. Therefore, the exponential function is used to express their complex interactions, which reflects the interaction between humidity and UV output and the decrease in effectiveness depending on the distance. The exponential function for the average temperature (E) of the use environment reflects the influence of temperature on the sterilization process. Since the influence of temperature on the sterilization process, especially on the growth of pathogens and the activity of the sterilant, can be exponential, a high temperature increases the growth rate of pathogens. This model exponentially models the sensitivity of the sterilization cycle to temperature changes, reflecting the fact that as temperature increases, the sterilization cycle should be shortened, as the need for sterilization increases accordingly. In other words, the use of this exponential function mathematically quantifies the influence of complex environmental conditions on the sterilization process, thereby establishing an effective and precise sterilization cycle, thereby improving sterilization efficiency and power consumption efficiency.

[0162] The downward slope angle of the square wing according to one embodiment of the present invention can be derived based on the following [Mathematical Formula 2]. Meanwhile, if the value derived through [Mathematical Formula 2] does not exist in the range of 10 to 50, it is considered as 10 if it is less than 10, and as 50 if it exceeds 50.

[0163]

[0164] [Mathematical Formula 2]

[0165] In the above [Mathematical Formula 2], Th (degree) represents the downward slope angle, F represents the elastic modulus (N / m²) of the material of the elastic opening / closing trap, G represents the thickness (mm) of the elastic opening / closing trap, H represents the width of the opening (cm), I represents the intensity of the UV light source used (milliwatts / square centimeter), and J represents the area (cm2) of the opening.

[0166] More specifically, in [Mathematical Formula 2], it reflects that the larger the elastic modulus of the material of the elastic opening / closing trap, the greater the downward slope angle can be maintained. As the value of G increases, that is, as the elastic opening / closing trap becomes thicker, it reflects that thicker materials are heavier and thus have difficulty maintaining the downward slope angle. As the value of H increases, that is, as the width of the opening increases, it reflects that the wider the opening, the more force the elastic opening / closing trap can receive and the greater the downward slope can be. As the value of I increases, that is, as the intensity of the UV light source used increases, it reflects that the downward slope angle can be made larger so that the sterilization effect is improved and the efficiency is higher. As the value of J increases, that is, as the area of ​​the opening increases, it reflects that the load on the elastic opening / closing trap can be distributed and the downward slope can be reduced. That is, the downward slope angle derived through [Mathematical Formula 2] according to the present invention is intended to optimize the effective opening and closing operation of the square wing part and the performance of the elastic opening and closing trap, thereby contributing to increasing efficiency and user convenience in the opening and closing process of the medical waste collection box (200).

[0167] In addition, the exponential function including the natural constant of [Mathematical Formula 2] enhances the influence by making the elasticity and thickness of the material more sensitive to the downward slope angle, and the width of the opening uses a logarithmic function so that the influence is reflected linearly on the downward slope angle, and the square root reflects the relative influence of the intensity of the light source and the area of ​​the opening on the downward slope angle. The optimization of the downward slope angle quantified mathematically in this way ensures easy input of waste and stable closing of the elastic opening / closing trap, thereby preventing medical waste from being exposed to the outside, and also contributes to infection control and hygiene maintenance within medical institutions, and plays a role in increasing the efficiency and reliability of the overall system for safe collection and processing of medical waste.

[0168] Meanwhile, a medical waste collection box according to one embodiment of the present invention includes a loading section in which a medical waste sterilization packaging is loaded, and based on a plurality of sensors provided in an area within the loading section, at least one piece of information among the shape, QR code, and weight of the medical waste is identified to generate a physical sterilization record including sterilization conditions, and the degree of completion can be identified after sterilization is completed.

[0169] Specifically, the loading unit is equipped with a shape recognition sensor, a barcode scanner, and a weight measurement sensor. The shape recognition sensor detects the size and shape of the medical waste using a camera or infrared sensor, and the barcode scanner identifies information about a specific medical waste by scanning a QR code attached to the sterilization packaging. The weight measurement sensor measures the weight of the medical waste placed in the collection box. The data collected from these multiple sensors is transmitted to the central processing unit and used to set the sterilization conditions. After the sterilization process is completed, the sterilization completion level of the medical waste is identified based on the data. This sensor-based system plays a crucial role in optimizing the sterilization process according to the characteristics of the medical waste and ensuring the accuracy and completeness of sterilization.

[0170] According to one embodiment of the present invention, a medical waste sterilization processing system collects and sterilizes medical waste using at least one of a sterilization packaging material or a medical waste collection box, and identifies whether the medical waste is sterilized based on at least one result of physical and microbiological qualification, thereby separating medical waste from which pathogens have been killed by material so that it can be recycled.

[0171] Specifically, the sterilization packaging is made of a material with controlled permeability to prevent the penetration of pathogens while allowing the sterilizing agent required for the sterilization process to pass through, and the medical waste collection bin uses this packaging to collect medical waste, and physical sensors and microbiological testing equipment are installed inside the collection bin to automatically perform qualification testing after the sterilization process.

[0172] Collected medical waste first undergoes a sterilization process, and then built-in sensors and inspection equipment determine whether pathogens within the medical waste have been killed. Once sterilization is confirmed, an automatic sorting system is activated to separate various types of medical waste by material, such as plastic, glass, and metal, allowing each type to be recycled. This enables efficient resource recycling, contributes to a more sustainable healthcare environment, and plays a crucial role in safely processing and recycling various types of medical waste generated in medical facilities such as hospitals.
