Braun Infusomat Space - Function

System Overview

1 - 4 Infusomat® Space 6.0 EN
Function
There are two power options for the Infusomat® Space:
- Via the inserted battery module
- Via an external 12 V DC power supply (e.g. SpaceStation,
SpaceControl, a
n external power supply or from an ambu-
lance car) connected to connector “P2”
The voltage supplied is converted to the internal voltages required
through a
voltage transforming and monitoring circuit on the
processor PCB.
An independent circuit in the battery mo
dule monitors the battery
cells and controls their charge condition.
The keyboard and the display are lighted.
The Infusomat® Space is connected to a SpaceControl by connec-
tor “P3”.
The function processor controls all the functions of the Infuso-
mat® Space. Data is stored in a non-volatile memory which also
co
ntrols the external data transfer.
The monitoring processor monitors all
important responses of the
function processor to incoming information. If a response does
not correspond with that expected by the monitoring processor,
an error message is generated and the device is switched to a safe
stop state.
The Infusomat® Space Line and its contents is monitored by the
s
ensors listed below:
- Optional drop sensor
- Pressure sensor upstream (container-side)
Monitors the upstream pressure (negative pressure)
- Air inline sensor
Monitors the line contents (liquid - air)
- Temperature sensor
Monitors the temperature of the m
edium in the line (inte-
grated in the air inline sensor)
- Pressure sensor downstream (patient-side)
Monitors the downstream pressure (overpressure)
The pump drive motor is monitored by a speed and direction of ro-
tation detection function.
The motor of the lock bolt drive is controlled via the processor
P
CB. The different positions of the lock bolt during operation are
monitored by a linear potentiometer.
