Cleaning Perivascular Probes
S & R-Series Probes (after use)
- Disassemble the probe, keeping all parts of each probe together because parts are not inter-changeable amongst probes.
- Thoroughly wash the flowprobe and its reflector bracket in soap and warm water (_55ºC, 130º F). Remove any visible foreign material with a soft bristled brush.
- Reinstall the reflector bracket in the alignment groove recessed on either side of the probe body taking care not to distort the shape of the groove or bracket.
M-Series (handle style) intraoperative probes
before sterilization:
- Thoroughly wash the flowprobe in soap and warm water (_55ºC, 130º F). Remove any visible foreign material with a soft brush.
- Wrap carefully for sterilization.
Cleaning Extracorporeal Sensors
XL-, or C-Series Sterile Tubing Flowsensors; N-Series In-line probes
Extracorporeal sensors can be damaged by immersion in saline or wet storage. They should not be boiled, or autoclaved. Nor should they be sterilized by cold liquid sterilization.
- Wipe with soap and water (60ºC, 140º F).
- Rinse with ethyl alcohol to promote drying.
Ethylene Oxide (EO) Gas Sterilization
Ethylene oxide, standard hospital cold (_60ºC, 140ºF), gas sterilization can be used for sterilization. Before sterilization, the probe may be rinsed and wiped in alcohol.
Follow the standard sterilization cycle time for your EO system.
Recommended parameters:
- Chamber temperature 119º - 131ºF
- Chamber humidity 45 - 75 % RH
- Load temperature 104º - 141ºF
- Load humidity 20 - 90% RH
- Gas Mix 10%EO, 90%HCFC
- Pressure 24.2 - 27.2 PSIA
- Aeration Time
- Heated Aeration 12 - 48 Hours
- Ambient Aeration 47 hours minimum
STERRAD Sterilization
Transonic Systems flowprobes are also sterilizable with STERRAD (not Steris). Total process time is a little over one hour. No aeration is required, and there are no toxic residues or emissions.
