HEART-LUNG MACHINE MAQUET HL 20
The HL 20 perfusion system meets and exceeds the
highest requirements for perfusion technology today: The
MAQUET HL 20 heart-lung machine combines the complex
technology needed for modern cardiopulmonary surgery with
the clear and concise overview and handling necessary for
safe and effective patient and operator management. Each
pump function is indicated by name, not by location and
the assigned function of each pump is displayed on its front
panel. All alarms and errors are indicated both acoustically
and visually. A single button on the system control panel SCP
is used to mute all alarms. Furthermore a remote control
for the MAQUET heater-cooler unit HCU20 is incorporated in
the SCP. Patient temperatures can be monitored and managed
without diverting the operator’s attention. The cardioplegia
monitor unit CMU can be fitted to the SCP allowing essential
cardioplegia data, including volume, ratio, times, temperature
and pressure to be displayed and managed.
Safe and reliable: In the event of mains power failure an
integrated and fully automatic battery backup system will
cut in automatically and power the entire system to allow
most surgical procedures to be completed. All pumps and
modules operate on low 24 V for increased patient and
operator safety. All electrical connections are inside the HL 20.
There are no protruding or interfering cables to be broken,
tangled or inadvertently unplugged. The short SCP cable
gives positioning flexibility to the system control panel. The
system performs an extensive self-test when powered up
and continuously monitors all vital functions during operation.
Ultimate data acquisition system: MAQUET’S Data Man-
agement System JOCAP XL records all perfusion data which
can be stored and then reviewed during and after operation.
The configuration possibilities that are available with JOCAP XL
are so extensive and flexible that most user requirements can
be easily met. A new concept for connecting external devices
directly to the JOCAP XL system has been successfully es-
tablished. It allows users to automatically acquire data from
a wide variety of operating room devices, such as blood-gas
and anesthesia monitors, giving them the monitoring and
data storage possibilities they have been requesting.
Flexible and adaptable to every operation: There are
different configurations for the heart-lung machine HL 20.
All controls and monitors are managed from a single panel,
which can be mounted on the mast in a number of different
positions using a special holder. Pump functions can be
renamed or relocated instantly without reconnection of a
single cable.
