17.2 Cleaning and Sterilization of the
N5402-REV2 Sensor
Remove the flow sensor connecting cable before
any cleaning, disinfection or sterilization.
Rinse the sensor body immediately after use and
put it into a disinfectant (recommended by the
infection control authority of the hospital/
organization), otherwise the sensor will encrust and
cannot be used any more.
Prior to first use as well as after each use Clean or
Disinfect/Sterilize the sensor.
Cleaning: A soap solution or mild alkaline
solution should be used.
Disinfection: Use commercially available
disinfectants that are recommended for
use with PLASTIC MATERIALS.
Immersion times and concentrations
stated must be in accordance with
manufacturer’s instructions.
Sterilization For sterilization a validated steam
sterilization according to BS EN554
can be applied. Autoclave at
134ºC (277ºF) (Allowable variation of
temperature of +3ºC) at 220kPa
(32psi) with a minimum holding time of
3 minutes.
or
121ºC (248ºF) (Allowable variation of
temperature of +3ºC) at 96kPa
(14.1psi) with a minimum holding time
of 15 minutes.
Before each use the sensor must be checked for
damage. Damaged parts must not be used.
Warning: Do not clean the flow sensor with
compressed air or water jet. As this will
destroy the sensor wires.
Note: Disinfectants containing compounds
similar to PHENOL or ALKYLAMINES
(Glucorrotamine) are unsuitable.
Note: Eliminate all residues of cleaning
agents and disinfectant used by thoroughly
rinsing with sterile water after each cleaning
and disinfecting procedure.

(Do not autoclave
or immerse in
liquids)
Note: The sensor must not be connected to
other standard connectors when sterilised to
prevent cracking. Ensure no other
components/items are lying on the sensor
during the sterilization process.
Warning: Do not use any nebulized gases
(medications, salt solutions, etc.) in
conjunction with the sensor as they are likely
to degrade the performance of the sensor and
subsequent displayed accuracies.
