reused between patients. It is therefore very important to minimise the risk of disease transmission by using barri-
ers and safe processing between patients.
Risk of infection
ALWAYS clean and disinfect the probe between patients to the level appropriate for the type of examination,
and use FDA-approved probe sheaths where appropriate.
Adequate cleaning and disinfection is necessary to prevent the transmission of diseases. It is the responsibility of the
equipment user to verify and maintain the effectiveness of the infection control procedures being used. Always use
sterile, legally marketed probe sheaths for intra-cavitary procedures.
Probe cleaning procedure:
Disconnect the probe from the system prior to cleaning/disinfection. Failure to do so could damage the system.
Clean the probe after each use:
Disconnect the probe from the ultrasound console and remove all coupling gel from the probe by wiping it with a soft
cloth and rinsing with running water.
Wash the probe with mild soap in lukewarm water. Scrub the probe as required using a soft sponge, gauze, or cloth
to remove all visible residue from the probe surface. Prolonged soaking or scrubbing with a soft-bristle brush (such as
a toothbrush) may be necessary if material has dried on the probe surface.
WARNING:
To avoid electric shock, be sure to turn off the system and disconnect power before cleaning the
probe.
CAUTION:
Take extra care when handling the lens of the ultrasound transducer. The lens face is especially sensi-
tive and can easily be damaged by rough handling. NEVER use excessive force when cleaning the
lens face.
Rinse the probe with enough clean, potable water to remove all visible soap residues. Dry the probe
with a soft cloth or let it dry in the air.
CAUTION:
To minimise the risk of infection from blood-borne pathogens, you must handle all probes and dis-
posable materials that have come into contact with blood and other infectious materials,
mucous membranes, and non-intact skin in accordance with the infection control procedures. You
must always wear protective gloves when handling potentially infectious material. Use a face shield
and gown if there is a risk of splashing.
Disinfecting the probes:
Disinfect the probes after each use.
Ultrasound probes can be disinfected using liquid chemical germicides. The de-
gree of disinfection is directly related to the duration of contact with the germicide. Increased contact time produces a
higher level of disinfection.
