Cast Operation is composed by manifold layers of special made glass
fiber which was soaked by polyurethane. Polyurethane material is
one kind of block copolymer which contains soft segment; it is
characterized by better viscosity, fast drying time, high rigidness
and light weight. Due to better biocompatibility, polyurethane is
widely used in medical places. Animal study and acute and chronic
toxicity test have proved that medical polyurethane was non-toxic
and no-induced distortion, no local irritation and no allergic
High rigidness, Light weight as polyurethane material is made up by
soft segment and stiff segment which will increase the cohesion and
rigidness, moreover, the consumption of cast operation will be 1/3
of plaster cast at the same fixed position.
Porous and good permeability;
cast operation is made with high quality raw yarn and unique mesh
weaving technique, which can make sure it has better permeability
and good for skin permeability. On the other hand, local skin hot
and itch problem caused by tube dress have been solved because of
Hardening process of cast operation is very fast and it only takes
3 to 5 min to start hardening and can bear weight after 20 min in
contrast with 24 hours hardening for plaster cast.
Excellent X-ray radiolucency
as cast operation is very excellent on the permeability of
radiation, the effect of X-ray is very clear to be seen so it is
helpful to the doctors to learn the healing of limb during the
when the cast is hardened, its surface is very smooth and the water
absorptive is 85% lower than plaster cast and common glass fiber
made cast and splint. Even if limb is touched with water, it can
make sure the affected area is dry, no worry to be soaked in water
for the second time and it is acceptable to take a bath and do
hydrotherapy when wore with the cast operation.
Convenient and flexible to be operated, good plasticity;
cast operation can be used when it is squeezed 2-3 times in normal
temperature water. If there are any skin traumas or operation time
taken too long on fixing place, it is not necessary to dip in the
water first, just fix it. When it was fixed, water can be sprayed
onto the external layers so as to step up harden speed. It has good
plasticity and high bending and tensile strength, so it can be bent
arbitrarily and made into tube shape or support.
Comfort and safety
it is convenient for doctors to make local plastic wrap as the soft
segment has better flexibility. B; As cast operation is with small
contraction, it will not bring skin tight and skin itch symptom to
the patients caused by plaster cast when it became dry.
Wide range of application
external fixing of orthopedics, correction utilities of orthopedic
surgery, accessibility tools for artificial limb, support tools,
local protective support of burn surgery etc.
Clinical characteristic contrast form:

The wound is handled easy to keep a hole
Innocuity has no chemical reaction
How to use
Wear the gloves and select suitable specification as required
Use cotton tallow packing or cotton-padded packing on the fixing
place as the backing.
Unpack it and take cast operation out, put the cast into water for
2-3 seconds and squeeze it for 2-3 times, make sure the extra water
is squeezed out.
Wind it into spiral with moderate tightness as required, 2-6 layers
on supporting place and 2-4 layers on non-supporting place.
Shape it as required and 3-5 min for hardening. It can reach the
functional rigid after 20min.
Demolish it by using electric plaster saw.
Operator must wear rubber glove in order to prevent polyurethane
sticking together with the skin. Use it immediately once it is
unpacked and it is not allowed to unpack several ones at the same
time. When it is going to torn down, electric plaster saw should be
used. Pay attention to the package and make sure it is sealed well
during the transportation so as to prevent hardness on the way. If
any quality issues found, please contact with producers or agencies
just in time.
