PRECAUTIONS FOR USE
This is a fragile product, please handle with care. Always
use the base plate on a flat surface. For safety reasons, the
base plate cannot hang over the table. Clear the
treatment table of any debris before positioning the base
plate.
Always fix the base plate securely to the treatment couch
before positioning a patient. More information on how to
fix this base plate to the couch top can be found on our
website:
www.orfit.com/en/fixation-devices
.
When a robotic arm is used to transfer the table onto a
stretcher with the base plate attached to it, the base plate
should be fully supported at all times. For safety reasons
the base plate cannot hang over the table. Always verify
that the base plate is attached safely to the table before
performing the transfer.
The glass fibre base plate is constructed to be light in
weight. When handled roughly, it may get damaged and
fibres may come off. When this happens, stop using the
base plate to prevent fibres from getting in contact with
the patient’s or user’s skin. Contact your distributor.
The article number and lot number can be found on the
back of the base plate. They are mentioned on the bottom
side of the plate in between 2 indexing holes at the edge.
