5. Cleaning and Disinfection of aView
The aView should be cleaned and disinfected before and after each use. It is recommended
that aView is cleaned and disinfected before and after use following the instructions below.
Ambu has validated these instructions in accordance with AAMI TIR 12 & 30. Any deviation from
the instructions should be properly evaluated for effectiveness and potential adverse consequences
by the reprocessor, to ensure that the device continues to fulfil its intended purpose.
Clean and disinfect the aView according to good medical practice using one of the
procedures below:
Cleaning
1. Prepare a cleaning solution using a standard enzymatic detergent prepared per
manufacturer´s recommendations. Recommended detergent: enzymatic, mild pH: 7 – 9,
low foaming (Enzol or equivalent).
2. Soak a sterile gauze in the enzymatic solution and make sure that the gauze is moist
and not dripping.
3. Thoroughly clean the button, rubber covers, screen, external casing of the monitor and
stand with the moist gauze. Avoid getting the device wet to prevent damaging internal
electronic components.
4. Using a sterile soft bristled brush that has been dipped in the enzymatic solution,
brush the button until all evidence of soil is removed.
5. Wait for 10 minutes (or the time recommended by the manufacturer of the detergent)
to allow the enzymes to activate.
6. Wipe the aView clean using sterile gauze that has been moistened with RO/DI water.
Ensure all traces of the detergent are removed.
7. Repeat steps 1 to 6.
Disinfecting
Wipe the surfaces of aView for approximately 15 minutes using a piece of sterile gauze
moistened with the alcohol mixture indicated below (approximately once every 2 minutes).
Follow safety procedures for the handling of isopropyl. The gauze should be moist and not
dripping since liquid can affect the electronics inside the aView. Pay close attention to the
button, rubber covers, screen, external casing and stand, slots and gaps on the aView. Use a
sterile cotton swab for these areas.
Solution: Isopropyl (alcohol) 95%; Concentration: 70 – 80%; Preparation: 80cc of 95% Isopropyl
(alcohol) added to 20cc of purified water (PURW) (Alternatively, use EPA-registered hospital
disinfection wipes containing at least 70% isopropyl. Safety precautions and directions of use
of the manufacturer must be followed).
After cleaning and disinfection, the aView must be submitted to the pre-check procedure in section 4.1.
Between procedures, aView must be stored in accordance with local guidelines.
