2.2 Operational description
From an operational point of view, the Volumat Agilia pump is made up of 3 sub-assemblies:
 a sub-assembly to maintain and to check the correct positioning of the administration set.
 a motorisation sub-assembly.
 an external connection sub-assembly.
2.2.1 Administration set check and maintenance sub-assembly
The administration set is positioned along the front part panel held in place by the door.
The front part is equipped with four detection systems:
 A detector to check the position of the door (closed /open).
 A photoelectric cell to detect the presence of the administration set clamp.
 An ultra-sound detector to detect the presence of air bubbles in the administration set.
 Detection of the pressure is ensured by two piezo-resistant sensors allowing the pressure
level control in the administration set.
2.2.2 Pumping sub-assembly
The pumping sub-assembly contains the peristaltic pumping mechanism.
The mechanism is made up of a camshaft that creates a wave-like movement in a bank of 12
"fingers". The displacement of these ’fingers’ is controlled by the CPU board, while turning it
displaces the liquid at the programmed flow rate.
The camshaft is driven by a stepper-motor and a reduction gearbox assembly via a toothed
belt.
A photoelectric cell and a rotation palette, situated on the camshaft end, to control the motor/
pumping system rotation.
2.2.3 External connections sub-assembly
Volumat Agilia has 2 plugs situated at the back of the angle bracket:
 a mains supply plug
 a 8 point Binder plug which, together with various specific Fresenius Kabi accessories,
enables the following functionalities:

Continuous external power supply

Nurse call

Serial link.
An infrared cell is located at the back of the device. It permits information to be exchanged
with the
Link
+
Agilia : the information can then be transmitted by dedicated communication
cables.
