DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sanitary package,
In particular, it relates to a medical device hygiene package for sterilization and disinfection of medical devices in medical, dental, veterinary, clinical examination, acupuncture and moxibustion.

[0002]

2. Description of the Related Art At present, various medical institutions, including dental care facilities, have a high public interest in measures for preventing hospital-acquired infections such as HIV (AIDS), MRSA, hepatitis B, and hepatitis C. In the health administration, there is a need for further enhancement and dissemination of nosocomial infections, as well as the establishment of simpler and cheaper surgical procedures. However, looking at the dental field, for example, most of the medical facilities are often private practitioners, each consisting of one dentist and three to five other staff members, and are limited in cost, equipment, and manpower. At present, it is not possible to take sufficient measures to prevent hospital-acquired infections.

[0003] Recently, many dentist's private practitioners are equipped with an autoclave (high-pressure steam sterilizer), and in principle, sterilization treatment equivalent to that of a surgical instrument is possible. However, due to its labor, cost, etc., a special package (sterile bag) like surgical instruments
It is rarely processed using a medical device. Currently, even instruments that have been sterilized and disinfected with great care are placed on a metal tray (hereinafter referred to as a tray) with bare hands under the polluted atmosphere in the clinic. In many cases, and the possibility of contamination is high. In addition, when transporting from a storage such as an ultraviolet sterilizer to a medical table, instruments are often dropped from the tray. If you place the tray on a treatment table, the tray is not large enough,
Therapeutic instruments may be placed on a table that has not been fully disinfected outside the tray. Furthermore, after the treatment is completed, the tray may become full of absorbent cotton or the like contaminated with blood, etc., and careless handling or transport from the clinic to the disinfection corner, etc. May fall and contaminate the surrounding area, or the surgeon or staff may be traumatized and become infected with the above disease.

[0004]

As described above, despite a strong demand for prevention of hospital-acquired infection, preventive measures have not been taken sufficiently. In particular, it is desired to establish a simple and inexpensive technique that can be easily performed by an individual practitioner who has limitations in personnel and equipment costs. In summary, the present invention has a problem to solve the following. (1) Sanitary sterilization and storage of instruments. (2) Hygienic use environment of the equipment. (3) Prevention of contamination of surroundings by contaminated equipment and prevention of infection of healthcare workers by prevention of trauma accidents. In the above example, the medical device used in the dental medical field has been described.
In addition, there were similar problems in sterilization, disinfection, storage, transportation, and the like of medical instruments used in medical departments, veterinarians, clinical examinations, and acupuncture and moxibustion. Therefore, an object of the present invention is to provide a sanitary package that can be sterilized, disinfected, and stored simply and inexpensively. It is also an object of the present invention to

It is di. The sanitary package according to the present invention is configured such that the temporary fixing portion or the vicinity thereof is opened so that the gas permeable sheet is developed to expose the sterilized and disinfected instruments therein on the gas permeable sheet. The temporary fixing part of the present invention is (1)
A configuration including an adhesive portion to the package body side and a cut line for separating and opening the adhesive portion; (2) a configuration in which a folded portion is further provided at a corner of a folded portion of the package; (3) a package A cut-out portion provided on the folded portion on both sides of the cut-off portion, and a cut-off protruding portion having the cut portion is provided on one folded portion,
(4) It is possible to adopt a configuration in which a cut portion provided at the folded portion at one end of the package is engaged with the folded side of the package.

In the present invention, a sanitary package containing medical instruments and the like is sterilized and disinfected by saturated steam heated in an autoclave, and all microorganisms attached to the contents are sterilized for each package. Sterilization conditions in the autoclave are in accordance with the standards of the Japanese Pharmacopoeia Law, and are as follows.
° C, 1.0 Kg / cm ² , 20 minutes, or 132 ° C,
Treated with 2.0 Kg / cm ² , heated saturated steam for 10 minutes. The sanitary package of the present invention must be made of a material that can withstand the above sterilization and disinfection conditions, and that has sufficient size and strength. The material of the breathable sheet for producing the package is made of a material having heat resistance, water resistance, and strength enough to withstand normal use without being damaged during sterilization and disinfection. As for the material of the breathable sheet, it is preferable that the sheet material itself is breathable. However, since the sheet can be made breathable by, for example, a method of forming a large number of holes in the sheet, a material having no breathability is used. Can also be used.

[0007] Materials satisfying the necessary conditions of the sanitary package include, as main components, paper, heat-resistant film made of synthetic resin having heat resistance of 140 ° C. or more, heat-resistant sheet, nonwoven fabric, and other heat-resistant materials. At the time of manufacture, from the purpose and method of use, as structural conditions, (1) easy storage of the device in the package, (2) easy sealing of the device in the package, and (3) The package is easy to open and unfold into a flat shape. (4) There is no fall of the equipment stored during unpacking and unfolding of the package. The device is manufactured in consideration of the fact that the device appears orderly and (5) low cost so that it can always be used in daily clinical practice.

[0008] The size of the package is arbitrary. The size developed in a plane is determined by the size of the required clean space, and the size when storing the equipment is the size of the equipment to be stored, a size suitable for sterilization, disinfection treatment, storage In order to change the size, the fabrication method (folding method) is changed and the fabrication is performed in consideration of the structural conditions. The form and manufacturing method of the package are determined under the conditions of the respective sizes as described above. Since it is manufactured so as to satisfy the structural conditions in accordance with the condition of each size, many forms and manufacturing methods are conceivable. The present invention is not limited to a particular bag type or envelope type package. In dental practice, the size of the package depends on the size of the sterilization autoclave and UV storage,
Approximately 20cm long side × 8cm short side, size when unfolded is 35
It is easy to use one with a size of about cm × 25 cm.

According to the method of folding the package, it is necessary to seal the contents such as a medical instrument in a package of the form of an envelope or an envelope, and the specific structure of the temporary fixing portion of the package after the folding is as follows. (1) Various adhesive tapes (including sterilizing tape) on the folded part
(2) bonding with various adhesives,
(3) A method in which a cut is made in each of the folded portion and the package body side so that they are engaged with each other. (4) A bridge-like projection is provided so that one of the folded portions overlaps the other folded portion. A method of bonding this overlapping portion with an adhesive tape, an adhesive, or the like; (5) Similarly, a method of making a cut in each of the overlapping portions so as to be engaged with each other; (7) A method in which a projection for insertion and a hole for receiving are provided and fixed with the projection and the hole, (7) A method of pressing and sealing the folded portion and a part of the overlapping portion on the package body side, (8) Package end And (9) a method of temporarily fixing the package end with various clips or staples (trade name).

The sanitary package of the present invention has been developed and researched on the condition that it can be easily opened and developed into a flat shape from the viewpoint of its development, and is intended to maintain the sterilized state of the contents for a long period of time. It is desirable to use the package for medical instruments and the like in which sterilization, disinfection, and use of instruments are repeated in a short period of time, instead of a rigid package to be sealed such as various existing sterilization bags. It is sufficiently possible to maintain a sterilized state for a certain period of time by changing the selection of the packaging material used, the sealing method, and the manufacturing method (folding method, etc.). In addition, since sterilization and disinfection processing using an autoclave uses high heat as described above, printing using a heat-sensitive material that changes color and discoloration due to temperature change is performed on the sheet, and adhesive tape containing the material is temporarily fixed to the sheet. It is also possible to make it easy to confirm sterilization and disinfection treatment by a method such as using it for an adhesive part.

Although there are many heat-sensitive materials, those which can be used in an autoclave show the following changes in color tone. Brown → green white → black, gray, black-brown light green → black red → brown blue → brown Using this heat-sensitive material, you can print the state of sterilization and disinfection processing such as day of the week, sterilization, etc., for example, the above five kinds of color differences It is also possible to specify a sterilization and disinfection processing date by using a plurality of packages according to the order in order every day, and to manage the packages so that they are used within a few days after the sterilization and disinfection processing.

[0012] In addition, when trying to prevent the infection of hepatitis B and AIDS simply instead of complete sterilization and disinfection,
Each virus is said to be neutralized under the following conditions: HBV (Hepatitis B): 98 ° C, 2 minutes HIV (AIDS): 50-60 ° C, 60 minutes Some household dish dryers use hot air of 80 ° C or higher. Even without an autoclave, the dryer can be used for disinfection using the package of the present invention. Also, a commercially available electric pressure pan can perform sterilization treatment equivalent to that of an autoclave.

Accordingly, the sanitary package of the present invention can be used in fields other than for medical devices. For example, scissors, razors, needles, and other instruments to which blood may adhere can be used in hairdressers, barbers, saunas, aesthetics, tattoos, and the like without fear of infection such as AIDS. Further, the package of the present invention can be applied to sterilization, disinfection, and the like of research and development instruments such as chemistry, biology, bacteriology, pharmacy, and hygiene. An object of the present invention is to provide a sterilized and disinfected space. In other words, this package is stored in an existing sterilization bag in case of an unexpected situation, and if used together, it is sterilized even in emergency medical treatment, traffic accident scenes, treatment in unsanitary environments such as outdoors. Can provide a clean treatment space. As described above, the package of the present invention is for preventing microorganisms and viruses from entering the inside of the package in a short period of time, and is not intended to maintain a sterilized state for a long period of time, and is also easy to open and deploy. Sealing is not required to achieve

[0014]

According to the present invention, sterilization, disinfection and storage can be performed without storing a medical device or the like directly into a package until the product is used after storing the medical device or the like inside the package. Occasionally, the package is opened and unfolded to provide a clean, sterilized, clean surgical field area, and after use of the contents, the contaminated contents are treated without direct finger touch. it can.
Sterilization in the present invention is to sterilize (exclude) pathogenic microorganisms or non-pathogenic microorganisms up to spores, and disinfection in the present invention is to sterilize (exclude, attenuate, remove only pathogenic microorganisms). Or dilution). In addition,
The spore is a durable form formed by a certain microorganism when the surrounding environment (such as nutritional state) becomes unsuitable for survival and growth, and as a kind of life cycle for maintaining the life until the surrounding environment recovers. Microorganisms that are deformed, do not easily die, and serve as standards for sterilization and disinfection. The contents of the sanitary package of the present invention appear in the center of the package when the package is opened and opened. For example, when using medical instruments in dentistry, by opening the package in front of the patient,
It is possible to clearly show each clinic's attitude toward prevention of hospital-acquired infection, and it is possible to eliminate anxiety about hospital-acquired infection in an easy-to-understand manner.
