We previously reported on needle damage to needles sterilized 50 times. This time we increased the number of sterilizations to 100 times and investigated needle damage. damage.Sterilization was performed using a small high pressure steam sterilizer at a temperature of 126°C for 25 minutes each time.1. Non-gold or silver needles had a tendency to become finer but there was no remarkable weight change noted.2. Resistance to bending tests showed that Chinese needles become more difficult to break.3. Elasticity tests showed that non-gold needles become easier to restore to their original state.4. Insertion tests showed that some needles, especially Chinese needles and stainless steel No. 3 needles, become more difficult to insert smoothly.5. Hardness and sturdiness tests showed a general decrease in both factors with the exception of hard silver No. 3 needles and Chinese needles which become sturdier.
