Description

Technical Field

[0001] The utility model relates to a high-pressure steam sterilization packaging bag for laboratories. Background Art

[0002] In order to prevent bacteria from growing and affecting the experimental results, various instruments used for experiments in the laboratory need to be disinfected and sterilized. High-pressure steam sterilization is generally used. However, there is currently a lack of packaging bags that can be used to place instruments to be sterilized. Laboratories often use kraft paper, non-woven fabrics, or even newspapers to wrap the instruments to be sterilized for sterilization. Since this single-sheet packaging material is not convenient to use, the experimenter needs to manually wrap and fold and seal it, which invisibly increases the additional labor cost. Moreover, single-sheet packaging materials are often discarded directly after one use, which also causes a lot of waste. At the same time, since it is difficult for a single-sheet packaging material to fully match various shapes and sizes of instruments to be sterilized, it may be difficult to completely cover the instruments during packaging, resulting in secondary contamination after the instruments are taken out of the sterilization cabin after sterilization. Moreover, before and after sterilization, the simple packaging is not convenient for operators to carry, and the operator who packs for sterilization and opens the package after sterilization may not be the same operator. As a result, during the unpacking process, the sterilized items may fall or slip out due to the operator's lack of understanding of the types of instruments in the package and how they are placed, causing instrument contamination and the need for re-sterilization, which in turn affects the progress of the experiment. In addition, the sterilization indicator card commonly used to mark the sterilization effect during sterilization is also difficult to fix on this simple packaging, which is not conducive to the operator's understanding of the sterilization situation.
