Cleaning the Ulco Integrus PSV

Introduction

Step-by-step guide to take apart and clean absorber and bellows assembly for an ULCO Integrus PSV ventilator.

To begin, make sure the ventilator is turned off and unplugged.

These should be cleaned each day that the ventilator is in use (usually at the end of the day).

NOTE: Screw types and lengths are not specified in manuals

Remove the silicone shutters by gently lifting from the base, NOT from the flaps.

To release and remove the canister(s), undo the handle latch by turning sideways.

Push canister(s) down then out of the cradle. Then dispose of the used soda lime (see suppliers recommended procedure for disposal of soda lime).
Wash all the absorber components. Do NOT use caustic cleaning fluids.
The Canister(s) and silicone shutters can be autoclaved.
The Absorber head can be put through a washer at 80 deg.C
Dry thoroughly before assembly, low pressure warm air should be passed through the head by attaching a hose to the expiratory port of the absorber.

Remove the bellows assembly by rotating counter-clockwise. The bellows canister may be washed or autoclaved.

The base disk (mushroom) should be removed from the bellows assembly before washing. Pull the latex-free rubber bag from the delrin base disk. The bellows may be washed or autoclaved. The base component (mushroom) should not be autoclaved but can be put through a washer at 80°C.
Dry all components thoroughly before re-assembly.
Low pressure warm air should be passed through the absorber head by attaching a hose to the scavenge port
