WORKING PROPERTIES
1. Cutting
ORFIT CRYSTAL NS is a very soft product. It can easily be cut
with a suitable pair of sharp scissors.
2. Activation
2.1. Activation in a water bath
ORFIT CRYSTAL NS is softened by heating at a minimum
temperature of
75°C –
77°C (167°F – 171°F)
.
Activation time: 10 min.
Take the material out of the water bath and cool down on a wet
towel or on a cool and smooth surface before applying it to the
patient.
!
Make sure that the temperature of the activated material will
not burn the patient.
2.2. Activation in an oven or with a dry heating device
ORFIT CRYSTAL NS is softened by heating at a temperature of
80°C – 90
°
C (176°F – 194°F)
.
Activation time: 5 to 7 minutes.
When using a dry heater, heating plate or a hot air oven, the hot
surface must be covered with a Teflon film.
When using a heat gun, do not exceed the set temperature of
250°C (482°F) to avoid breakdown of the material.
High temperatures up to a maximum of 180°C (356°F) do not
damage ORFIT CRYSTAL NS, but are not user-friendly. Higher
temperatures are allowed on the condition that the activation
time is reduced accordingly.
!
Wear gloves and do not apply ORFIT CRYSTAL NS
directly to the
patient's skin at high activation temperatures.
!
Never use an open flame to activate ORFIT CRYSTAL NS.
3. Application
Let ORFIT CRYSTAL NS cool sufficiently before application on the
patient.
ORFIT CRYSTAL NS is:
Temporarily cohesive when wet heated (min 80°C-176°F), dried
thoroughly on a towel and pressed together firmly.
Reactivation in hot water, by dry heater or in a hot air oven is
possible.
Permanently cohesive when dry heated (min 80°C-176°F) after
scraping off the NS coating.
4. Application of hook and loop tape:
Hook and loop tape can be used to make sure the patient can
easily put the orthosis on and off whenever desired or necessary.
Use one of the following techniques to apply hook and loop tape
onto the ORFIT CRYSTAL NS orthosis:
4.a. Technique 1: D- strapping
1. Cut a piece (6-8 cm) of double-sided velour loop tape (art.
No. 35444L).
2. Cut a small piece (2-3 cm) of double-sided micro hook tape
(art. No. 35444H).
3. Cut a small longitudinal incision (25 mm length = width of the
double-sided velour loop tape) at minimum 1 cm distance
from the edge of the orthosis. Cut a second small incision at
the contralateral edge of the orthosis at the same level of the
first incision.
4. Glide one end of the double-sided velour loop tape into one
of the incisions and glide the other end of the tape in the
contralateral incision (from inside to outside).
5. Let both ends of the loop tape overlap each other (in the
middle of the two orthoses edges) and attach the small piece
of double-sided micro hook tape between them.
6. Make the orthosis fit the patient correctly by pulling the free
ends of the loop tape towards each other and strap them
tightly enough on the hook tape.
