MOX1 MediceL® Sensor
Poisoning
CiTiceLs are designed for operation in a wide range of environments and harsh conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments and operation.
When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the
sensor is fitted. Do not glue directly on or near the CiTiceL as the solvent may cause crazing of the plastic.
Intended Use
These sensors are designed to be used to monitor the partial pressure of oxygen in anaesthesia (not including xenon), critical care, neonatal incubators, and general oxygen monitors.
Stabilisation Time
Allow at least 15 minutes to stabilise in the instrument before calibration or refer to manufacturers instructions.
Cleaning and Sterilisation
In case of contamination the sensor may be cleaned with distilled water and allowed to dry naturally. The sensor is not suitable for sterilisation by steam or exposure to chemicals such as ethylene oxide or hydrogen peroxide.
Calibration Interval
These sensors are designed to have minimal drift over their useful lifetime. For maximum accuracy however they should be calibrated before each use.
If the Sensor is Dropped
If a sensor is dropped, then it should be placed in quarantine for 24 hours and a follow-up check made by a 2 point calibration.
Mechanical Installation
When installing the sensor, it must only be screwed in hand-tight and a gas tight seal ensured. Spanners and similar mechanical aids may not be used, as excessive force may damage the sensor thread.
RFI/EMI Susceptibility
MediceLs contain metal and may be susceptible to RFI or EMI. They are not suitable for use in MRI environments. For further information please contact City Technology.
Cross Sensitivity
The table below shows how MOX1 MediceLs respond when tested with the gas mixtures listed in ISO 80601-2-55.
