Biopsy Needle Cleaning Method Step 3

Method three: disinfection and washing

1) Boiling disinfection for 10 minutes: After boiling for disinfection, count for 10 minutes after boiling, and pay attention that the tube cavity is filled with boiling water.

2) Soak and disinfect with 500mg/l chlorine-containing disinfectant for 20-30min.

When soaking, the needle plug is filled with disinfectant, and the disinfectant is replaced regularly to prevent the puncture needle from rusting due to too long soaking time. After disinfection, use normal water to flush the disinfectant inside and outside the puncture needle.

Rinse quality evaluation: the puncture needle has no cleaning agent and disinfectant residue.
