PROCEDURE
IX.A. Preparation of Incubator.
IX.A.1.
Before cleaning PNICU piglet incubator, unplug the power cord from wall receptacle
and remove micro air filter. Note: Filter must not get wet.
IX.A.2. Use handle on back of plexiglass hood to lift hood forward.
IX.A.3.
Remove incubator bedding tray.
IX.A.4.
Lift the deck rest and remove (deck must never rest on deck gasket).
IX.A.5.
Wash the plexiglass incubators.
IX.A.5.a.
Wash with disinfectant cleaning solution. Use a soft cloth to clean
because the plexiglass will scratch very easily.
IX.A.5.b.
Rinse the plexiglass incubators with tap water.
IX.A.5.c.
Never use alcohol on the incubators because it could result in cracks or
fissures to the plexiglass.
IX.A.5.d.
Clean piglet incubator humidifier air reservoir with disinfectant cleaning
solution.
IX.A.5.e.
Check the micro oxygen filter for cleanliness and change if necessary.

IX.B.4.
Remove oxygen intake tube (turn and pull forward) and clean with disinfectant and a
clean cloth.
IX.C. Clean the humidity fill tube located on left front below hood.
IX.C.1. Unscrew the humidity fill tube and clean tube. Note: Use caution because they are
easily broken.
IX.D. Clean the humidity reservoir tank and baffle with disinfectant cleaner and soft cloth.
IX.D.1.

Place a squirt bottle of saline and 70% alcohol, and box of KimWipes on top shelf of
incubator, for use during 24-hour care.
IX.D.5.
Place two autoclaved piglet floors on the bottom of each incubator so that they
overlap,f or use during 24-hour care.
IX.D.6.
Put an autoclaved teddie (towel or linen) in each incubator, for use during 24-hour
care.
IX.D.7.
If needed, set a baby bottle nipple (that has been autoclaved in water) in the bottle
holder on the outside of the incubator if available or tape the nipple to the rear inside
wall of the incubator to be used as a pacifier, for use during 24-hour care.
IX.D.8.
Place a wiffle ball that has been soaking in a disinfectant solution on the piglet floor,
for use during 24-hour care.

IX.E.1.
Wash the painted base cabinets with disinfectant solution.
