Figure 4 - 3: Moving the System

4.3 Fluid Delivery Basics The system is a programmable power injector that enables an operator to generate a defined fluid delivery protocol and execute a fluid injection.

4.3.1 Protocol A protocol defines how the fluid injection will proceed and is comprised of three elements: phases, a pressure limit, and optional reminders.

4.3.1.1 Phase Phases are steps that define the actual movement of fluid, pauses, and/or holds. There are three types of phases: Q

Fluid Delivery Phase: Defines the flow rate, volume, and duration of a fluid to be injected.

4 - 12

MEDRAD® MRXperion

Q

Pause Phase: Defines a set amount of time that fluid injection will be paused. The next phase will execute once the set time has elapsed.

Q

Hold Phase: Places the fluid delivery in Hold. The operator must press the “Start” button on the Pod, injector head or hand switch.

4.3.1.2 Pressure Limit The pressure limit defines the maximum fluid pressure the system is permitted to generate during the execution of the protocol. The default maximum pressure limit is 325psi (2,240 kPa) when using the recommended disposable syringes from Bayer. The operator may choose to reduce this pressure limit based on the conditions for use of the protocol.

4.3.1.3 Reminders Reminders are optional, operator-defined timing notifications that appear during the injection sequence or after the sequence completes. Reminders provide a notification to the operator after a defined time has elapsed. There are two types of reminders: Q

Standard reminders: Occur during the protocol execution and are triggered by the initiation of the injection.

Q

Post-injection reminders: Occur after the protocol is complete and are triggered by the completion of the injection prior to disconnecting the patient.

4.3.2 I Checked for Air Before the system can be armed, the operator must visually check that all air has been expelled from the syringes and tubing. After the operator has determined that all air has been expelled from the syringes and tubing, the operator can either press the I Checked for Air confirmation button, or acknowledge on the notification screen on the display.

4.3.3 Test Injection An optional, operator-defined saline test injection can be delivered before the protocol is initiated.

4.3.4 KVO (Keep Vein Open) An operator-defined function that delivers small boluses of saline from Syringe B at configurable intervals during programming, pre-and post-injection, between multiple injections, and/or during Pause and Hold phases.

4.3.5 Protocol Manager Using Protocol Manager, the operator can name, save, and recall protocols.

4.3.6 Fluid Delivery System Design The system is flow-controlled by three parameters: flow rate, duration, and volume. The system permits the operator to define any two of these three parameters and will automatically calculate the third: Q

The flow rate specified in a phase is the value the system targets to deliver during the injection until the defined phase volume is delivered.

Q

The duration is the defined time the phase will take to perform the volume injection at the stated flow rate.

Q

Volume is the amount of fluid that will be delivered in a phase.

Operation Manual

4 - 13

4.3.7 Fluid Pressure and Pressure Limiting The fluid pressure is measured by the system during the execution of a phase and ensures the protocol Pressure Limit is not exceeded. Fluid pressure is dependent on the following: Q

Flow rate

Q

Fluid viscosity

Q

Fluid temperatures

Q

Attached syringes and connector tube

Q

Catheter type/size

Pressure Limiting occurs when the measured fluid pressure exceeds the protocol Pressure Limit setting. If this occurs, the system informs the operator of the condition and initiates Flow Rate Reduction for the Fluid Delivery phase to reduce the fluid pressure.

4.3.7.1 Flow Rate Reduction A slower flow rate is automatically initiated by the system to prevent the fluid pressure from exceeding the Pressure Limit. The system will deliver the phase volume at this reduced flow rate. The fluid delivery phase will exceed the programmed duration when Flow Rate Reduction occurs.

4.3.8 Response to Occlusions When injecting into an occlusion, a stall condition or high pressure disarm results. A stall condition occurs when the actual flow rate is less than 10% of the defined rate. If a stall or high pressure disarm occurs, check the fluid path for blockage and inspect the syringes and connector tube for damage or kinks. If no issue is found, consider increasing the catheter size, removing administration sets, or decreasing the flow rate. If an occlusion occurs during KVO, the system will detect the condition after 4 or less KVO boluses fail to be delivered. (The occlusion will be detected after 1 minute or less if the KVO interval is set to 15 seconds or after 5 minutes or less if the KVO interval is set to 75 seconds.) Refer to "Section 15.4 - Fluid Delivery Setup" for information about setting KVO intervals.

4.3.9 Volume and Flow Rate Protection The system provides the following protection against over and under volume or flow rate conditions: Q

Warnings on the Safety Screen to remind the operator to check the protocol prior to the system being armed.

Q

On-screen indications of insufficient volume when the total programmed volume is greater than the amount of fluid in the syringe.

Q

Injection monitoring to detect over flow rate or over volume conditions due to system faults. If either of these conditions is detected, the injection is stopped.

4.4 Syringe Installation Features

 CAUTION Mechanical Hazard - Minor or moderate patient and/or worker injury may result. Q

Ensure the syringe is properly snapped into the front of the injector head before injecting.

Q

Improper engagement or rotating syringe may cause the syringe to leak, become damaged, or to disengage from the injector head during the injection.

The system is designed with four features that decrease the time and steps to install and remove syringes to the injector head. (For more information about configuration of these features, see "Section 15.4 - Fluid Delivery Setup".) 1.

Non-rotational orientation: When installing a syringe onto the injector head, alignment is unnecessary. Push the 65mL syringe into opening A and the 115mL syringe into opening B.

4 - 14

MEDRAD® MRXperion

2.

Auto Docking: When Auto Advance is configured to be ON and a new empty syringe is installed, the injector piston automatically advances and docks with the syringe plunger.

3.

Auto Advance: When Auto Advance is configured to be ON and a new empty syringe is installed on the injector head, the piston automatically docks with the syringe plunger and advances it to the full forward position.

4.

Auto Retract: When Auto Retract is configured to be ON and the syringe is removed, the piston rod will automatically retract into the injector head.

4.5 Basic Informatics If the optional Informatics platform is included with the system, please refer to the Certegra Workstation Informatics Panel and Modality Worklist Operations Manual for overview and functionality.

4.6 Programming Mode The system allows the operator to enter values for two of the three parameters in the Fluid Delivery Phase. Based upon these operator-defined values, the system calculates the value of the third parameter. The system default configuration is for the operator to enter values for flow rate and volume and the system calculates the duration. Using Programming Mode (see "Section 15.4 - Fluid Delivery Setup"), the operator can select which of the three parameters (flow rate, volume, or duration) the system will automatically calculate based on their entries for the remaining two parameters.

4.7 Using the Pedestal with Integrated IV Pole The pedestal with integrated IV pole is on casters and can be located anywhere within the MR scan room to facilitate the enhanced MRI procedure.

WARNINGS Electric Shock Hazard - Serious patient and/or worker injury or death may result. Q

Turn off any equipment that could generate a high level electrostatic charge.

 CAUTIONS Mechanical Hazard - Minor or moderate patient and/or worker injury may result. Q

Tighten all screws, clamps, and knobs during assembly and as needed during use. Loose components may cause the pedestal to collapse.

Q

Do not move or manipulate the injector by pulling or pushing the integrated IV pole. Using the IV pole to maneuver the injector could bend the IV pole or cause the injector to fall over. Maneuver the injector as instructed in "Section 4.2 - Moving the System".

Q

Do not move the injector when anything is hanging on the Integrated IV pole.

Q

Use care and diligence in folding and unfolding the IV pole hooks. Keep hands and fingers clear of all pinch point areas.

Q

The IV pole folding hooks are designed to hold a maximum weight of 0.33 lbs (0.15 kg) or 150mL of fluid. Do not exceed the weight limit.

Q

Do not coil or hang cables from the IV pole.

Q

The pedestal is intended to support the injector head in an MR scanner room. Do not attempt to use the pedestal for any other purposes.

Electric Shock Hazard - Minor or moderate patient and/or worker injury may result. Q

Only plug the system into a direct AC outlet.

Q

Do not plug the system power cords into an extension cord or multi-outlet power strip.

Q

Use only approved adapters and accessories from Bayer.
