Whether your measurement device be a fine Swiss watch or a Transonic flowprobe, proper care is crucial to its continued reliable functioning. Because of their size, it is sometimes easy to forget that Transonic flow probes are highly technological pieces of equipment. The exact alignment of the reflector in relationship to the probe is critical for accurate measurements. Abuse of the probe can result in inaccurate measurements, malfunction or non-function of the probe. We recommend that you carefully examine your probes when you receive them and store them in their boxes when they are not being used.
NOTE: Never boil or autoclave your probes. Also, do not attempt to clean them in an ultrasonic cleaner.
Cleaning Perivascular Probes
PS-, PR-, PAX-, PAA- Probes, S-, R-, A-, V-Series Probes (after use)
- Disassemble the probe, keeping all parts of each probe together (Important: Parts are not interchangeable 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.
PMP-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.
XL-, or C-Series Sterile Tubing Flowsensors;
XN-, or N-Series In-line Sensors
Extracorporeal sensors can be damaged by immersion in saline or wet storage. They should not be boiled, autoclaved, or sterilized by cold liquid sterilization.
- Wipe with soap and water (?55ºC, 130º F).
- Rinse with ethyl alcohol to promote drying.
Ethylene Oxide (EO) Gas Sterilization
Ethylene oxide, standard hospital cold (?60ºC, 140ºF) gas sterilization, can be see for sterilization. Prior to sterilization, the probe may be rinsed and wiped in 70% 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 flow probes are also sterlizable 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.
Liquid Sterilization and Disinfecting Solutions Various solutions are widely used to disinfect surgical equipment. Great care should be used when applying any of these agents to Transonic Systems probes.
