1.1. Sterilization pouches IFU (instructions for use).The instruction applies to Mediwish® combined self-adhesive sterilization bags produced by Mediwish Co., Ltd (hereinafter referred to as bags).

1.2. Packages are intended for packaging medical devices subject to sterilization (steam, ethylene oxide, steam-formaldehyde and radiation), in order to ensure their sterility upon sterilization during storage and transportation until intended use.

1.3. Packages are intended for single use.

1.4. The bags meet requirements European standard EN 868 for packaging materials for sterilization, as well as requirements ISO 11607-2014 for packaging materials. The bags are semi-permeable, i.e., steam during sterilization enters inside, after sterilization air freely enters. Thus, internal environment pouches are balanced with physical parameters external environmental conditions, but microorganisms in air do not penetrate into such packages.

1.5. The instruction is intended for personnel medical institutions using packaging, as well as for employers services and institutions that have right to engage in disinfection activities.


2.1. The bags are a rectangular envelope made white paper and a transparent multi-layered polypropylene / mylar film, with one or more class 1 chemical indicators (according to ISO 11140-1-2014) that allow you to distinguish packages that have been sterilized from those that have not been sterilized. On protruding part paper side bag (valve), an adhesive layer is applied, protected by anti-adhesive paper. The bags are sealed with an adhesive self-adhesive strip without use a special sealing device.

2.2. In accordance with requirements standards for packaging for sterilization, packages provide, subject to requirements this instruction:

  • - reliability gluing (sealing);
  • - permeability to appropriate sterilizing agents;
  • - maintaining strength and integrity during and after sterilization;
  • - a reliable microbiological barrier and preservation sterility after sterilization.

2.3. Transport container.

3.1. The package is chosen in such a size that product to be sterilized is placed freely and occupies approximately 3/4 volume and length. This is necessary to prevent damage to pouch during packaging.

products, ease sealing and compensation for expansion package during vacuum stage (during steam sterilization).

3.2. Before use, check quality all packages. It is forbidden to use package if it contains holes, material ruptures, foreign inclusions, violations integrity seam, signs wetting (warping, streaks).

3.3. Packed washed surgical linen and medical devices that have undergone pre-sterilization treatment must be dry.

3.4. When using packages, products that have a working and a non-working part (for example, a surgical instrument) are placed in a package so that non-working part is facing opening package. The party opening packages is party with a three-layer seam (bottom) a package. Direction opening is indicated by a special scheme located in middle part bottom sterilisation pouch.

3.12. After sterilization, sterilization bags with products must have a residual moisture content that complies with regulatory requirements (for example, according to EN 285:2015 Sterilization - Steam sterilizers - large sterilizers). Excess moisture reduces strength bags and significantly reduces shelf-life sterile products.

ATTENTION! It is not allowed to use bags that are damp, wet, with visible moisture inside.

3.13. If necessary, packages with products that remain wet after sterilization (for example, in sterilizers without vacuum drying), immediately upon sterilization, are dried with an open sterilizer chamber, or in a drying cabinet or in an air sterilizer at a temperature not exceeding 80 ° C.

is changing. If sterilization conditions are met, indicator mark reaches color reference element or becomes darker than it, which indicates that required values ​​​​ critical variables are met.

sterilization process. In this case, products are considered sterile and must use for their intended purpose.

Full or partial preservation original color indicator label, which is easily distinguishable from color indicator comparison element, indicates that required conditions for effective sterilization are not met. Therefore, devices with indicators that have not reached final state are considered non-sterile and must be re-sterilized.

3.17. The pouches are opened from side non-working part tool by de lamination method. To do this, free ends paper and film are clamped with fingers and adhesive line is torn.


4.1. The manufacturer guarantees, subject to rules storage and handling packaging materials, compliance with standards for protective properties packaging for a total period 5 years. This means that shelf-life packaging is 5 years from date manufacture.
