10.1 Cleaning and sterilisation
Cleaning, general
Wipe the instrument case, transducers, event marker, fetal ECG electrode leg plate
and IUP extension cable with a cloth dampened in soap or detergent solution to
remove aquasonic gel, blood, saline etc. Wipe dry with a clean cloth.
Disinfecting the maternal ECG lead
1 Wipe with a cloth soaked in a solution of chlorine bleach in water (no stronger
than 1:10 mixture) or in a 2% Glutaraldehyde solution, such as Cidex.
2 Wipe the lead with a clean damp cloth, then a clean dry cloth.
Caution: do not use isopropyl alcohol. Do not expose metal components
(eg snap connectors) to chemicals.
Disinfection, general
Clean the instrument case, transducers etc. as described above. Then wipe with an
alcohol-impregnated wipe (70% ethanol or isopropranol).
Sterilisation
The only method of sterilisation for case and transducers is by using Ethylene Oxide
gas (up to 5.5 bar). Low-temperature steam is NOT permissible.
Note: sterilisation is not normally required.
Transducer care
Transducers should be kept dry and preferably below 45°C. Gel must be wiped from
the ultrasound transducers after use, and before placing on the storage area on the
side panel.
