Sterilization Processes for Medical Devices
What kind of sterilization methods can be used for a medical device? There are different methods for the sterilization of medical devices, using gas and steam or radiation. Radiation methods: The principle of this form of sterilization treatment is to bombard the sample with high energy electrons or high energy electromagnetic radiation. This activity leads to the formation of unstable free radicals, molecular ions, and secondary electrons. These products react with molecules and fracture their chemical bonds. DNA and RNA are sensitives to this sterilization approach. The advantage of this technique is that products can be sterilized through radiation after packaging due to the penetrating power of the incident gamma-ray. Nevertheless, some drugs like heparin cannot be irradiated because there is a risk of changing…
