Care of the Instrument

Main Unit

Keep the instrument clean by wiping it periodically with a damp cloth and mild disinfectant
cleaner.  DO NOT immerse in fluids or use solvent cleaners.

Doppler Probes
Caution: 

DO NOT USE organic cleaning agents or alcohol.  DO NOT immerse the probes

in liquid.  Only a probe specified as waterproof shall be immersed in water.

DO NOT drop or knock the probe against a hard surface. DO NOT pull on the transducer
cable.

Note: 

The following steps are recommended for the cleaning and  disinfecting of

VIASYS probes before each use.  The procedure renders clean probes which are
neither sterile nor pyrogen free.  When carried out according to standard clinical
practice, it should help prevent the transfer of infectious agents, through the elimination
of significant microbiological contamination between uses.

Regularly clean off the remains of the conductive gel. The probe should be wiped clean with
a soft nonabrasive cloth or disposable wipe soaked in an aqueous disinfectant.  Avoid aerosol
preparations of disinfecting agents, since they may contain alcohol or organic solvents.

The probe should then be wiped with a nonabrasive cloth moistened with water.

Clean, dry probes should be packaged in clean bags, covered trays, or other suitable
systems for storage and transport.

The probe assembly should be examined on a daily basis and inspected for cracks which
allow the ingress of the conductive fluid. The probe cable and associated connectors should
be examined for any damage on a daily basis. DO NOT USE any probe which shows any
signs of damage. The user should ensure that all probes are regularly tested for electrical
safety.

If sterilization of the probes is desired, it can be done with cold gas sterilization (such  as
ethylene oxide at less than 140° F), or the Sterrad™ System.  The user is responsible for
verification of sterility.  Follow the manufacturer’s instruction for your model.

Note: 

Only sterilize the probe with these methods. Do not sterilize the main unit in this

manner.

Elite 

will not be in use for an extended period. Do not expose to

temperatures greater than 65°C  (149°F).
