Parts marked are autoclavable. Metal and glass parts can be steam autoclaved. Maximum
commended temperature is 134ºC. By using autoclave to solidify bacterioprotein rapidly, quick
and reliable disinfection can be achieved. Suffered from 15 to20 minutes of 1.05 kg/cm
2
steam
pressure and 121ºC temperature, all bacteria and most blood cells are killed.
Such parts are washable by hand. Rinse and dry all parts of the breathing system except the O
2
sensor completely by using mild detergent (pH ranging from 7.0 to 10.5).
Warning
◆
Do not use talc, zinc stearate, calcium carbonate, corn starch or equivalent materials to
prevent tackiness. These materials can go into the patient’s lungs and airways and cause
irritation or injury.
◆
Do not put both of the breathing system and the O
2
sensor in liquid or autoclave them.
◆
Inspect all parts for deterioration. Replace them if necessary.
All parts of the breathing system can be cleaned and disinfected. The cleaning and disinfection
methods are different for different parts.
You need to select the appropriate method to clean and disinfect the parts based on the actual
situations to avoid cross-contamination.
This table is our recommended cleaning and disinfection methods for all parts of the breathing
system.
The following is our recommended disinfection method:
