7.0 PRESSURE REDUCTION REGULATORS
For optimum performance of the Mini-Vitreous Probe CR4045, a standard pressure reduction regulator
should be used to reduce the gas pressure delivered to the CR4000 system. A suitable two-stage pressure
reduction regulator is used instead of the cylinder connector. The gas pressure from the cylinder should
be adjusted to indicate 625psi on the CR4000 front panel gauge.
A pressure reduction regulator
is only recommended for the Mini- Vitreous Probe CR4045. For all
other probes, the pressure should be set between 680 and 900psi(700psi is preferred), within the green
zone of the front panel gauge. Contact your MIRA representative for more information on pressure
reduction regulators.
8.0 PROBE CARE
8.1
Use
The Ophthalmic Cryo probes must be handled with care. They are non-electric and are
easily inserted or removed from the console’s receptacle. Do not use the probe if the tip is
scratched or damaged. Return scratched or damaged probes to MIRA for repair.
WARNING;
Do not alter the shape of the probe tip. The shape of the probe tip is vital to
its proper function. Any change to the probe tip will void the manufacturer’s warranty.
8.2.
Cleaning
The probes can be cleaned in accordance with the published protocol.
The entire probe
should never be submerged in any solution
. The probe jack cap should always be
attached during cleaning or sterilization to prevent foreign particles from entering the
body.
8.3
Storage
Storing the probes in tight coils is not recommended. Coil loops should be a minimum of
6 inches. The white caps will protect the probe tip and probe jack when being transported
or stored.
8.4
Sterilizing
CR4000 probes are made of stainless steel, Teflon and silicone rubber. The probes should
be sterilized in accordance with hospital protocol and Mira, Inc. IFU. It is the user’s
responsibility to select the sterilizing conditions that do not harm these materials. These
materials will tolerate steam sterilization.
WARNING;
The probe jack cover must be screwed into place before sterilizing
regardless of the sterilizing methods used. If moisture from steam or gas enters the probe
during sterilization, it will adversely affect the performance of the system.
Please ensure that the probe tip cover is on at all times when the probe is not in use.
