Green Sensor system

Brown Actor system

Black Electronic communication system

Purple Optical communication system

The medium gets aspirated from the relevant container (CA1, CA2, NaCl) into the pump hose.

The hose runs through an ultrasound sensor (US sensor CA1, US sensor CA2, US sensor NaCl),

which detects the presence of liquid or air (bubbles) in the hose system. The subsequent block-

ing valve (CA1 valve, CA2 valve, NaCl valve) controls the flow. In idle state the pump hose is

squeezed and the flow is stopped. When the blocking valve is triggered, an electromagnet (CA1

magnet, CA2 magnet, NaCl magnet) is activated which operates the valve plunger via a Bowden

cable and releases the flow of the relevant medium. The switching state of the valve is registered

by a micro switch. The same construction is found three times: once for saline solution (NaCl)

and twice for contrast agent (CA1/CA2). The valve door and NaCl hinge work as a counter bear-

ing. The state of the valve door is also registered by two micro switches (valve door 1, valve door

2).

Once the blocking valves are passed, the three hoses merge at the cross piece into a common

hose that leads to a venting unit (squeezer). An electromagnetically operated metal lever

squeezes the hose repeatedly to push the enclosed air out of the hose system and back into the

media containers. The blocking valve of the squeezing access must be opened during this pro-

cedure. The state of the squeezer is registered by a micro switch.

The system receives its required drive from a roll pump. The pump wheel is powered by a 24

VDC motor with an attached gearing, controlled by the micro controller (µC). An optical encoder

on the motor shaft and an optical sensor (light barrier) in connection with a slotted disc on the

pump axis ensure the proper monitoring and controlling of the pump rotation speed and thus of

the set flow rate.

The pump wheel is accessible via the pump flap, the state of which is registered by two micro

switches (pump flap left, pump flap right). The liquid-filled pump hose is located between the

pump wheel and the pump flap. Three identical rollers which are attached to the pump wheel

push the liquid ahead. The pump flap operates as a counter bearing. After the roll pump another

ultrasound air sensor (air trap) is integrated into the system. This sensor, however, is considera-

bly more sensitive than the three US sensors installed after the media containers. The air trap is

able to detect and add up even smallest air bubbles.

The subsequent, redundant pressure measurement system (pressure sensor 1, pressure sensor

2) detects the system pressure: if necessary, it regulates system pressure by aligning the pump-

ing rotation speed, or, in extreme cases, aborts the injection. A pressure-dependent piston is

integrated in the pump hose and puts pressure on a piezoelectric sensor, which transforms the

system pressure into an analogue voltage signal. The pressure control does not react to single


3-31

peaks but is based on an algorithm of averaging. This algorithm eliminates the impact of system

inherent peaks.

In addition, a particle filter is integrated into the pump hose. It is placed in a guided holder and

controlled by a micro switch. The patient hose is connected to the pump hose by a Luer Lock

connection. Two check valves have been integrated to prevent retrograde contamination. The

cannula is connected to the patient hose and leads into the vein of the patient to inject the me-

dium of the hose system. An additional micro switch monitors the state of the compartment lid

that covers the electronic unit (only for MRI injectors).

The control system contains two essential parts: the micro controller (µC) and a programmable

logic chip, the so called safety-logic.

Together with the program memory (EPROM), the micro controller controls and monitors the

injection procedure. The safety-logic monitors security-relevant aspects and operates absolutely

independently from the micro controller. Signals from all sensors reach both the controller and

the safety-logic. All actors receive separate enable signals from the micro controller and the

safety-logic. Both signals are necessary to activate the actors.

Before every injection, the micro controller checks the operational reliability of the safety-logic. In

this way both units constantly check each other.

In addition to controlling and monitoring the complete injection procedure and verifying the

safety-logic, the micro controller is also responsible for the serial communication and actuation of

the control unit via an I²C-Bus. Furthermore, the controller is connected with the terminal via opti-

cal fibers (fiber optic cable), which is used by the user to enter and modify injection programs.

A combined reset/watchdog unit is responsible for processing the reset signal. A voltage monitor

is integrated to monitor all power supplies of the injector and the measurement values of the

pressure sensors.
