6 Product description
6.1 Introduction
The ASTOPAD consists of a control unit and optionally one or two applied parts
(blankets, pads, OR table pads or mattresses).
WARNING
Danger of overheating!
For patients from 35 to 90 cm in height, use only the ASTOPAD applied parts
COV070 and SOF7
Do not use the ASTOPAD applied parts COV105, COV150, COV155,
COV180, SOF2, SOF4, SOF5, ROE4 or ROE8 for patients under 90 cm in
height.
6.2 Technical description
The ASTOPAD control unit can be secured to a round pipe (e.g. infusion stand) or
a medical standard rail.
The ASTOPAD control unit has two outputs (connecting sockets) A and B for con-
necting the ASTOPAD applied parts. The required set temperature of each con-
nected applied part can be selected, independently of one another, in a range
from 32.0°C to 39.0°C in 0.5°C increments. Optionally, the system can also be
operated with only one of the outputs A or B connected. The selected set temper-
ature and the actual temperature of each applied part are displayed on the control
panel.
The ASTOPAD control unit can also be operated via the battery option, independ-
ent of the mains. With battery inserted, operation is possible for about 2 hours in-
dependent of the mains.
With the exception of the COV155 heating blankets, which were exclusively de-
signed as blankets for the upper body, the ASTOPAD applied parts COV can be
used as over-blankets for warming the patient from above and/or as under-blan-
kets for warming the patient from below.
The heated, pressure-relieving OR table pad ASTOPAD applied part SOF or ROE
offers a combination of hypothermia and decubitus prophylaxis.
The key component of the ASTOPAD applied part SOF is a visco-elastic foam,
combined with a dynamic foam base for the best possible decubitus prophylaxis
on the OR table.
The special ASTOPAD applied part ROE is X-ray permeable and based on an op-
tionally 40 mm or 80 mm thick visco-elastic foam with a maximum sensor-free
zone.
