EN Infusomat® Space 6.0
The safety clamp squeezes the Infusomat® Space Line when the
operating unit is opened or internal calibration is carried out to
protect the patient and prevent an uncontrolled drug flow to the
patient. Beside the position monitoring via the lock bolt, the
"open/closed" state of the safety clamp is monitored by a light
barrier. The safety clamp is closed and the Infusomat® Space Line
is squeezed mechanically when the slide clamp of the Infusomat®
Space Line is inserted. When the operating unit is opened the slide
clamp is pulled out of the safety clamp until the Infusomat®
Space Line is pinched. The safety clamp is only opened by manual
operation of the safety clamp lever and the Infusomat® Space
Line can be removed.
To ensure patient safety the operating unit is automatically
locked. For this purpose, the operating unit is manually pressed in
the lock bolt with the three locking pins. The resistance of the lin-
ear potentiometer which is monitored by the controller is
changed when the position of the lock bolt changes. Locking is
started and can take up to 10 seconds. During locking, several cal-
ibrations are carried out automatically, for example:
- occlusion test
To check, for example, the function of the safety clamp
- pressure calibration of the two pressure sensors.
The operating unit is also unlocked automatically via the lock bolt.
In case of a power failure or malfunction, the operating unit can
be unlocked manually by a small emergency release crank. To do
this, the lock bolt is moved manually with the crank to the open
position, as described below.
