AVEA ventilator systems 187
L2786 Rev. M
Chapter 8: Maintenance and Cleaning
Cleaning and Sterilization
The AVEA is designed for easy maintenance. All exposed parts of the ventilator are corrosion resistant.
CAUTION!
DO NOT submerge the ventilator or pour cleaning liquids over or into the ventilator.
DO NOT sterilize the ventilator. The internal components are not compatible with sterilization techniques.
DO NOT gas sterilize or steam autoclave adapters or connectors while attached to the tubing. The tubing will, over
time, take the shape of the adapter, causing poor connection and possible leaks.
To minimize cleaning and replacement frequency, the AVEA design places the exhalation manifold, flow sensor and
diaphragm behind the exhalation filter and water trap.
Limitations on Reprocessing
There are instructions supplied by other manufacturers for individual parts and accessories that are included with the ventilator.
Follow those directions for processing between patients.
Instructions
Point of Use: Follow your institutions procedures for removing material from a patient area for processing.
Preparation for Decontamination: There are no special requirements regarding Preparation for Decontamination for these
parts.
Automated Cleaning: Follow cleaning instructions below. No specific automatic cleaning devices have been validated.
Manual Cleaning:
Cleaning External Surfaces: All external surfaces of the ventilator (the Exhalation cartridge included), can be wiped
clean with one of the following: Isopropyl Alcohol or Chlorine Compounds with a maximum concentration of 1:10.
Cleaning Accessories and Parts: ONLY the following three parts are cleanable using an enzyme pre-soaking solution:
The Water Trap (PN 50000-40035), the Infant Hot Wire Flow sensor (PN 16465) and the Water Collection Jar (PN
33985)
1. Prepare an enzyme based pre-soaking solution such as Klenzyme® (made by Steris Corporation, Mentor, OH) or
equivalent in accordance with manufacturer's instructions, using sterile distilled water at 20-30 degrees Celsius (68-86
degrees Fahrenheit)
2. Immerse the part to be cleaned in the prepared solution for 2-5 minutes, making sure that all lumens and air pockets are
completely filled with the solution, and agitate periodically.
3. Remove the part from the solution after 2-5 minutes and rinse immediately by immersing in at least 1 gallon of sterile
distilled water at 20-30 degrees Celsius (68-86 degrees Fahrenheit). Leave the part in the rinsing bath for at least 1
minute agitating periodically to ensure thorough rinsing.
