INSTRUCTIONS FOR USE
HP PRO® SOLUTION
OVERLAY BASE PLATE
MRI COMPATIBLE
Article No. : 25000/1/MR
A. GENERAL PRODUCT INFORMATION
This product is a medical device used for patient positioning and
immobilisation in radiation therapy. This low density plate can
be used during both the simulation and the treatment stage,
including MRI simulation.
B. PRODUCT DESCRIPTION
This glass fibre BASE PLATE is the basic element of the ORFIT HP
PRO SOLUTION. It is used in combination with special 3 and 5
point masks, a cranial stop and a personalized head rest to form
a reproducible patient positioning and immobilization device.
C. 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.
D. STORAGE
Always store the product in a safe place to prevent it from
getting damaged. Take care not to damage the edges of the
plate when storing it in an upright position. Prevent hard
objects from falling onto the plate. Store the base plate
between +10°C (50°F) and 40°C (122°F).

G. HP PRO THERMOPLASTIC MASKS
Various thermoplastic masks are available in a 3-points and 5points version to immobilize head and neck patients.
To attach the lateral head profiles to the base plate you have to
work in a few steps. First slide the caudal side of the profile over
the indexing pin and secondly swivel the profile inwards until it
clicks over the base plate.
Attaching a lateral profile to the base plate:
Removing a lateral profile from the base plate:
The cranial head profile and the shoulder profiles simply click
onto the base plate.
If the patient has medium to long hair it is helpful to add a hair
cover. This will automatically clear the areas where the mask
profiles must be attached. It provides more time to mould the
mask and prevents hair getting stuck in between the mask
profile connection.
Different shapes and sizes are available both in Efficast and
Nanor. The profiles are made from Polycarbonate (PC).
H. MAINTENANCE AND WASTE MANAGEMENT
This product can be cleaned and disinfected by means of soapy
water or an isopropanol based disinfectant, applied with a soft
cloth. If unsure about the cleaning fluid, do not use. Never use
aerosol sprays, corrosive cleaning agents, solvents or abrasive
detergents.
Periodic checks of the product should be done to insure the
parts are not worn and require repair or replacement. Do not
attempt to make repairs yourself. Contact your distributor if
there are any questions or concerns.
The product can be disposed of with household waste.
Periodic checks of the following parts is extremely important in
order to safeguard a good fixation of the mask to the base
plate:
The holes where the mask profiles click into.
The guidance ribs to position the mask profiles.
The pin to attach the inferior part of the profile to the base
