CLEANING & STERILIZATION (Continued)
Sterilizing the bellows base from the controller and bellows interior surface: The bellows and its
interior surface do come in contact with the breathing gas, and require periodic sterilization.
Sterilization is accomplished with the bellows housing and bellows removed, as described above.
The pop-off valve, and the 300-ml bellows adapter, if used may remain on the base during
sterilization.
To remove the bellows base from the controller for sterilization, disconnect the hoses from the
base and loosen the four black thumbscrews, located at the corners. First, clean the base using a
clean, soft, slightly dampened cloth. Then wrap the whole base and steam sterilize it using the
same standard hospital techniques as used for any surgical apparatus.
Finally, clean and sterilize the bellows using an appropriate hospital technique for delicate latex
supplies. DO NOT steam sterilize the bellows.
After completing the above sterilization procedures, complete the reassembly of the unit by first
reattaching the bellows base to the ventilator control unit, reconnect the hoses, and slip the first
convolution of the bellow over the bellows mounting ring. Then and finally, reattach the bellows
housing to the base. This completes the cleaning and sterilization procedures.
