Disinfection of enema device

Enema is not aseptic operation, but light wine is definitely not good. Before using the catheter, it can be boiled in boiling water for 20 minutes, but it may wear the catheter, which is a better disinfection method. Or disinfect with iodophor, which is convenient, but it is not cooked well. If a new disposable syringe is replaced every time, there is no need for disinfection.
