6.1 Introduction
ASTOFLO ECO PLUS consists of a control unit and a heating profile.
ASTOFLO ECO PLUS is a device for specific heating of blood and fluids which
are delivered to the patients by transfusion, infusion or irrigation. The warming of
the liquid supports the prevention and therapy
of hypothermia during or after
surgery; during longer procedures such as dialysis, hemofiltration, or apheresis
the warming leads to a well-being. The applications of the ASTOFLO PLUS ECO
therefore include transfusion, infusion, dialysis, hemofiltration and apheresis.
The ASTOFLO PLUS ECO Warmer can be used to warm fluids administered to a
patient at low flow rates (0 to 2000 ml/h, i.e. 0 to 30 ml/min), see figures 1 to 3.
Even at very high flow rates ASTOFLO PLUS ECO keeps pre-heated infusions
and fluids to the patient warm.
The heating profile is considered as "applied part" (IEC/EN 60601-1).
6.2 Technical description
During operation of the Warmer heat is transferred from the internal heating wire
to the heating profile. Commercially available infusion sets can simply be inserted
in the flexible groove of the heating profile. The heat from the heating profile is
transferred through the infusion sets to the fluid to be warmed.
The temperature of the heating profile is monitored by a microprocessor control-
led temperature control system and by independent alarm systems designed to
alert the operator to failure conditions and, if necessary, to switch off the heating
process automatically in the event of excessively high temperatures.
During operation, the control panel shows the internal temperature of the heating
profile; this is not equal to the temperature of the medium to be warmed. The
ASTOFLO PLUS ECO neither regulates nor monitors the current temperature of
the medium to be warmed. The temperature of the medium to be warmed
depends on a variety of factors, such as, but not limited to additional factors:
room temperature and ventilation
inlet temperature of the fluid (warmed-up or cold)
flow rate
material of the infusion set (PVC, EVA, PU)
