not remove the exhalation control tube from the cover.) Visually check if
there are any defects in the membrane. Take apart all three components of
exhalation valve (cap, membrane and housing).
3. Disassemble the Flow Sensor and the Y-Connector.
Washing
NOTE It is recommended to use Multi-tierd Endozime AW Plus or similar cleaner
solution to remove all bio-burden material. If using Endozime, dilute one-half
ounce (15 grams) of Multi-tierd Endozime AW Plus in 1 gal of water (3.8 liters).
1. Immerse the patient circuit components in the diluted Endozime for 10-20
minutes or equivalent cleaner solution. Pass solution through the small
diameter tubing by using syringe or connect to flow source of automatic
washing equipment.
Remark: It is possible to use automatic “medical standard” washing equipment
used in medical institutes for washing purposes. Wash according to preset
washing cycles, and use different adapters to pass cleaning solution through the
thin tubes.
2. Remove the patient circuit components from the solution and rinse the
components with distilled or sterile water. Pass water through the small
diameter tubing by using syringe or connect to flow source of automatic
washing equipment. Patient circuit components must be dried at 70°C for 2
hours prior to sterilization process.
Sterilization
CAUTION DO NOT TAKE APART THE THIN SILICONE TUBES WITH THE LUER CONNECTIONS.
if any component appears discolored or damaged in any way, dispose of the
part and replace the patient circuit. Do not use any patient circuit in which the
function of a component appears compromised.
Use the following autoclave parameters:
Form of Autoclave:
Steam Autoclave
Sterilizer Type: Pre-vacuum assisted steam saturated
autoclave
Method: Wrapped
Sterilization Time:
30 minutes
Reassembly
Following sterilization of the components, reassemble the patient circuit as
follows:
