Inditherm's blood and fluid warming
system uses solid state technology to provide ultra-fast
warm-up and excellent performance over a wide range of flow rates. The design
uses standard, low-cost consumables reducing running costs.
The carbon polymer is combined with a viscoelastic foam pad to give
unrivalled heat transfer characteristics. The pliable heating surface provided
by the polymer allows it to be placed above the pressure relieving pad, ensuring
that there is no attenuation of the warming performance. The combination of
these two materials allows the heating surface to mould itself to the shape of
each individual patient, giving the largest possible area of contact. The
viscoelastic properties ensure that the warming mattress returns to its original
flat surface once the patient is removed, ready to be used for the next case.
The mattress is encapsulated in a latex-free, nylon fabric cover, with
non-microporous polyurethane coating, which is fully sealed with RF welded
seams. This unique design ensures that the highest possible thermal transfer
characteristics can be achieved, giving the best warming performance
available.
Heating Technology
A high thermal transfer, solid-state heat exchanger is used, with black
anodised surface, to ensure effective warming of blood and fluids. The heating
spiral is contoured for efficient heat transfer and simple, fast
insertion of fluid lines. An exceptional heating path length ensures that
maximum warming of the fluid is achieved.
Enhanced Warming
NormoTherm XT has an enhanced
performance, using a heated sheath to continue warming the blood or fluid
between the warming unit and the patient. This is especially important when
using low flow rates.
Reliability
The design is robust, ensuring it is suitable for the operating room,
emergency room and transport environments. The system has no moving parts making
it very reliable. Temperature sensing uses thermistor technology, and
therefore does not need regular calibration.
Safety
The patented safety and control system, with three independent temperature
sensors, gives complete reliability. The sensor positioning ensures that an
accurate measurementof the blood or fluid temperature is achieved under all
circumstances. An automatic over-temperature shut-off is provided for added
security. The system does not use water or air, and is designed so that it is
easy to clean, to help avoid infection risks.
