Embodiment 1
[0016] A dry heat sterilization indicator, its components and the mass parts of each component are:
[0017] 3 parts of methylaminoanthraquinone, 5 parts of polyvinylpyrrolidone, 90 parts of mannitol
[0018] After the above components are uniformly stirred for 25-40 minutes, they are sent into a tablet machine for tablet compression. Finally, put the tablet into a device with an absorbent paper core and seal it to obtain a dry heat sterilization indicator.
Embodiment 2
[0020] A dry heat sterilization indicator, its components and the mass parts of each component are:
[0021] 1 part of methylaminoanthraquinone, 10 parts of polyvinylpyrrolidone, 90 parts of mannitol
[0022] After the above components are uniformly stirred for 25-40 minutes, they are sent into a tablet machine for tablet compression. Finally, put the tablet into a device with an absorbent paper core and seal it to obtain a dry heat sterilization indicator.
Embodiment 3
[0024] A dry heat sterilization indicator, its components and the mass parts of each component are:
[0025] 10 parts of methylaminoanthraquinone, 10 parts of polyvinylpyrrolidone, 50 parts of mannitol
[0026] After the above components are uniformly stirred for 25-40 minutes, they are sent into a tablet machine for tablet compression. Finally, put the tablet into a device with an absorbent paper core and seal it to obtain a dry heat sterilization indicator.
[0027] During monitoring, put the above-mentioned dry heat sterilization indicators, biological indicators and articles to be sterilized together in packaging materials, and use a closed method for packaging. After packaging, put it in a dry heat sterilizer for sterilization. The sterilization temperature is 160°C, and the sterilization time is 2 hours. After the sterilization is finished, take out the above-mentioned package, the sterilization indicator covers the entire absorbent paper core, and the biological indi...
