Sterilized pouches for medical devices is an emerging field of development. It can be said that it belongs to the emerging industry all over the world and is still in the process of accumulation and summary, especially in China.In 2005 or so began to understand the medical equipment pouches, and gradually with the international medical equipment sterilization pouches.7 years be taken seriously further by home place.Introduction of medical device sterilization bags medical device sterilization pouches should be understood as: the definition of the packing for medical device products, can to sterilization, aseptic operation can be performed, such as clean open), can provide acceptable performance of germs, to protect the product before and after sterilization and sterilization after can within a certain period of time (with) the period of validity of pouches systems for maintaining the system within a sterile environment.Because this concept usually does not include the outer protective pouches system (buffer pouches and assembly pouches, etc.), medical device sterilization pouches system can also be called "sterile barrier system".About medical device sterilization pouches forms, generally has the following three categories: 1.1 soft vacuum forming - filling, heat sealing pouches system: this type of pouches according to the forming part of the substrate thickness and can be divided into flexible and semi-rigid type two kinds, the substrate on specific blister pouches equipment through the adjustment of the temperature, vacuum and pressure absorption and thermoforming become upfront design good shape, and the corresponding top material and thermal bonding, form a three-dimensional molding pouches system meets the requirements.This kind of pouches features are: high degree of automation, high efficiency, low cost of a single pouches, pouches system and contents with good shape, but involves equipment and mold, have a certain request for production, usually used in the production scale is big, 2 kinds of medical equipment products, such as all kinds of syringe, gauze piece, gown and medical catheter intubation, three categories of medical apparatus and instruments, as well as the simple typical such as intravenous indwelling needle!

1.2 hard blister box cover material packing system: this class is to use all kinds of forming blister pouches box directly with all kinds of suitable for heat sealing and shape according to the cutting good heat sealing cover material in advance, and the so-called hard blister, is more used for vacuum forming and sheet thickness, usually between 0.4 1.2 mm, and the materials involved, from low-end to high-end mainly PVC, PP, PE, PS, PET, PETG, PC and so on, especially in PS, PET, PETG these three materials commonly used;Because PVC involves safety and environmental protection issues, there is a trend of gradually being eliminated;PP and PE, two conventional polymer materials, due to the limitations of their physical and mechanical properties after molding, are not used very much in this field;PC is because of the high cost, only in a very few areas of application, such as the need for dry heat sterilization occasions.This kind of hard blister box is generally purchased, and then in the medical device manufacturers and cover material for heat sealing, ordinary heating heat sealing equipment can be.1.3 all kinds of bag body pouches system: including all kinds of bags: paper and plastic bags, top bags, window bags, breathable strip sealing bags, paper bags, aluminum foil composite bags with Tyvek and other products, more forms may be designed and produced according to the actual situation, in short, it is difficult to completely summarize the types and application range!In China, these products, such as the top bag, window bag and breathable strip sealing bag and other products because of its special design of breathable window, save the cost of materials, by many medical equipment enterprises welcome.Sterilization bags from the 2006 edition of the latest relevant laws and regulations standard, formally issued in April 2006, has two parts, the first part is mainly about pouches materials, sterile barrier system and packing system, the second part is mainly about the relevant medical device sterilization pouches process validation problems, thus the aseptic packing according to the system design and pouches process to confirm the two apart from the body content.More importantly, in this version, formal absorbed the European popular EN868 standard system, already cancelled EN868-1 the conflicting general principles of the system, the selective absorption merger EN868-2 to 10 the nine sub standard for specific materials and products, it is in fact declared the global uniform standard of medical device sterilization pouches finally was born in 2006, both ISO11607-2006.Others, such as YY/T0698 performed on December 1, 2010, are converted GB/T19633, astm-f88 sealing, astm-f1929 staining penetration, ASTM F1980 accelerated aging, yyt_0681.1-2009 _ aseptic medical device pouches test method part 1:Accelerated aging test guidelines, ISO15223 / YY0446 medical equipment label tag and provide the information of symbols, GB/T191 pouches storage and transportation graphic symbol, ASTM, GB/T 15171 bubble F1608 microbial barrier test, no blasting (ASTM/ASTM F F - 1150-2054), the basic principle of sterilization bags < pouches sterilization gas sterilization factors such as size aperture size < bacterial size, sterilization pouches materials through the sterilization factor (such as ETO epoxy ethane, high temperature steam, cobalt 60 gamma rays, etc.),But it prevents the bacteria from being semi-permeable. 

In order to design a reasonable system of medical device sterilization pouches, need to follow some basic principles: 3.1 "pouches" is part of the product: the pouches here refers to the sterile barrier system, because of the sterile barrier system failure means that medical device failure, and possibly the latent risk is bigger, because this kind of failure is often more difficult to detect or more easily overlooked.Therefore, for the product developers or technical designers in the medical device industry, special attention should be paid to this point, and the product pouches design should be given priority, because this is also a part of the product design.3.2 "primary pouches systems" = "sterile barrier system:" this and the first point is mutual echo, and in ISO11607-2006 on the current international related medical equipment has the most direct the most authoritative standard, it directly in the previous version of the "early pouches system is redefined as' sterile barrier system, which is the concept of the original source.3.3 emphasis on the safety of the pouches and continuous stability: because of the particularity of medical equipment products, the pouches or not is directly related to the safety of the use of the instrument down the patient's life safety (of course some low-end medical devices may not have so serious consequences), in this life is the highest s, no one can ignore it.To achieve the absolute safety of sterilization pouches, experienced professional companies or personnel in the consulting industry, the selection of proven qualified pouches materials, sufficient and scientifically based experimental design and strict experimental operation, and reference to historical experience and experimental data that are considered to be correct should be taken into account.As for the emphasis on the continuous stability of pouches quality, this is under the condition that the major premise of sterilization pouches safety has been met, and then we should consider the problem, in fact, this is also a requirement to meet the absolute safety of pouches.

According to decades of industry experience at home and abroad, in addition to strictly abide by the ISO13485 quality management system standards designed for the medical device industry, in general, scientific and strict pouches process confirmation is also an effective way to ensure the continuous and stable pouches quality.Sterilization bag function in EO for epoxy ethane/STEAM high temperature STEAM/GAMMA irradiation cobalt 60 / plasma radiation sterilization, loading for sterilization of medical devices into the bag, seal tightly closed again after the implementation of sterilization, sterilization gas, ray through the bags in sterilization, analytical, and finally, the bacteria are not to go, because of the aperture is half permeability of pouches materials, allowing the sterilization gas, ray, prevent bacteria) is the choice of using the bags through a semipermeable dialysis, guarantee of medical equipment in the pouches, so after sterilization, the handling, transport,The storage is sterile until the hospital operating room nurses open it, the nursing book is finally opened directly with, no need to sterilize, the effective period of the material resistance of different pouches bags is generally 3-5 years, in the case of the pouches bag is not damaged, the medical equipment in the pouches bag can ensure 3 to 5 years are sterile.Sterilization bags of sterile barrier system evaluation, according to the product pouches material selection, the evaluation content includes: system requirements - microbial barrier system - products and pouches materials for validation pouches material biocompatibility and toxicity of physical and chemical properties of the material - - the adaptability - pouches materials and pouches materials and the sterilization process of forming and sealing process adaptability - pouches and label printing adaptability of pouches material of microbial barrier system evaluation based on 7.2: AGAR touch attack test of ISO 11607-2003.Question: is this test method out of date?Is the test method of F1608 necessary? This method can only be tested by a third party.Evaluation method of physical and chemical properties of pouches materials: test the tensile strength of pouches materials before and after sterilization, and compare the changes in the tensile strength of pouches materials before and after sterilization with the adaptability of pouches materials to the sterilization process.Before sterilization, the product shall be tested for the initial contamination bacteria, and after sterilization, the product shall be tested for sterility, and the suitability of the pouches material and the molding and sealing process shall be evaluated:- thermal sealing strength according to ASTM F1886:1998 Standard test method for determining integrity of seals for medical pouches by visual inspection - Standard test method for burst testing of flexible pouches according to ASTM f88:2000Pressurization within restraining plates used internal air pressurization.The integrity of the pouches - according to ASTM F1929:1998 "Standard test method for detecting seal leaks in porous medical pouches by dye penetration."
