変色程度を調節するのが困難でありその変色領域が実際
の滅菌条件にそぐわない場合が多かった。Conventionally, the so-called autoclave sterilization method using heated high-pressure steam has been widely used as a method of sterilizing medical equipment, food, etc. However, in reality, the steam distribution inside the high-pressure machine, temperature distribution, instrument failure, etc. Poor sterilization due to operational errors and deterioration and deformation of objects to be sterilized due to overheating are currently occurring.
It is not easy to judge whether sterilization has been completed or not, and one way to manage these problems is to attach indicators that change color when heated with steam to the objects to be sterilized or insert them into various parts of the fabric. However, with conventional indicators, it was difficult to adjust the degree of color change depending on various factors such as temperature, time, and water vapor pressure, and the area of color change often did not match actual sterilization conditions.
