Advantages of Ethylene Oxide Sterilization
What are the advantages of ethylene oxide sterilization (EO sterilization)?
In the sterilization technology of medical devices and sanitary products, the application of ethylene oxide gas sterilization is relatively extensive and the technology is mature. As early as the 1960s, advanced countries in the world have applied ethylene oxide gas sterilization technology to medical, sanitary, industrial, agricultural environmental sanitation and other fields. my country also began to widely apply these fields in the early 1990s.
The specific advantages are as follows:
① It can be used to sterilize items that are not resistant to high temperatures and moisture.
② Ethylene oxide is considered to be a chemical sterilizer with good sterilization effect, which can kill all microorganisms including bacterial spores.
③ It has strong penetration and can be used to sterilize various difficult-to-penetrate parts: for example, some thinner and longer catheters are difficult to sterilize with other low-temperature sterilization methods.
④ Little damage to items. Since EO kills microorganisms by using the alkylation principle rather than the oxidation process, it causes very little damage to items and has a very wide range of uses for sterilizing heat-sensitive precision instruments.
⑤ During sterilization, it can be wrapped with various wrapping materials for easy storage and transportation. It can be used after opening the package to avoid the risk of cross contamination.
⑥ There are standard chemical and biological monitoring methods, so that the sterilization quality can be effectively controlled and the packages that fail to sterilize can be found in time.
⑦ There are decades of experience in use.
The specific features are as follows:
Sterilization and residue removal: completed in one go, making production consistent and convenient.
Adopt hot water circulation heating system: save energy and heat quickly.
Safety: The sterilization process is carried out under negative pressure to ensure that ethylene oxide gas does not leak. It does not corrode or damage items, is easy to store, and does not pollute the environment.
Strong penetration: broad-spectrum sterilization, strong penetration, thorough sterilization, and sterilization at low temperature.
Convenience: The best combination of temperature, pressure, vacuum sterilization time, and residue removal times can be set according to sterilization needs.
Simple: Use microcomputer solidification program, just press the start button to realize automatic heating, vacuuming, humidification, dosing, nitrogen addition, sterilization, cleaning, tail gas treatment and other complex working procedures.
Forced analysis: Overcome the disadvantage of long natural dispersion time of sterilized objects, and achieve the standard residual amount less than 10ug/g
Single-dose gas cylinder dosing: Use 100% ethylene oxide gas cylinder, use one bottle for each sterilization, avoid leakage, easy to place, safer and more reliable.
