6 Product description
6.1 Introduction
The ASTOPAD Patient Warming System is a thermal regulating system which
includes a connection cable that attaches to reusable conductive warming blan-
kets for patient warming in clinical environments. The system consists of a con-
trol unit (DUO310) and one or optionally two applied parts (warming blankets).
WARNING
Risk of overheating!
•For pediatrics under 90 cm in length/height,use only the applied part ASTO-
PAD COV070.
•Do not use ASTOPAD COV105 or COV155 or COV180 for pediatrics under
90 cm in length/height.
6.2 Technical description
The ASTOPAD control unit (DUO310) is equipped with a universal mounting
clamp for attaching to standard medical equipment rails or an infusion stand, two
outputs for connecting one or two applied parts, connection to mains by detacha-
ble power supply cord, connector for potential equalization, the electronic boards
and the control panel for the user/operator.
The control unit has two outputs (connecting sockets) A and B for connecting
ASTOPAD applied parts. The desired set temperature can be selected in the
range of 32.0 °C - 39.0 °C in 0.5 °C increments for each connected applied part,
independently of each other, on the control panel of the control unit. The control
unit can also be used with only one of the outputs, A or B. The selected set tem-
perature and the current temperature are displayed individually for each applied
part in the control panel.
The control unit supplies the applied part(s) with electrical current (low voltage)
and monitors and controls the temperature of the applied part(s). When error
conditions occur, the control unit draws the operator's attention to the error condi-
tion by means of alarm signals (optical & acoustical). In the event of failure condi-
tions (overheating, heater defect, sensor defect), the control unit reacts immedi-
ately by shutting off the power supply to the applied part.
Optionally the control unit can be fitted with a battery. When the battery is in-
stalled, it is possible to operate the device independently from the mains for ap-
proximately two hours.

ASTOPAD®Instructions for Use
20
The ASTOPAD DUO310 control unit does not control and indicate the actual
temperature of the patient, but rather only the actual temperature of the applied
part.
Temperature regulation of the individual applied parts is performed with several
integrated sensors.
Safety of ASTOPAD is guaranteed by the following measures per output:
•Several temperature sensors for each applied part
•Double independent sensor monitoring
•Heater monitoring
•Time shut-off
•Visual and acoustic alarm signals
•Overheating and low-temperature alarm if the contact surface tempera-
ture deviates from the temperature controller setting
