Medrad Spectris Solaris MR Injector System This manual contains important information about use of the Medrad Spectris Solaris MR Injection System. Medrad urges you to read this manual carefully, become familiar with the procedures and system functions that it describes, and follow its recommendations to assure proper use of the system. Labels on the system or statements in this manual preceeded by any of the following words and/or symbols are of special significance, intended to help you to operate the system in a safe and successful manner: WARNING: Indicates that the information is a warning. Warnings advise you of circumstances that could result in injury or death to the patient or operator. Read and understand the warnings before operating the injection system. CAUTION: Indicates that the information is a caution. Cautions advise you of circumstances that could result in damage to the device. Read and understand the cautions before operating the injection system. Note:
Warnings
Indicates that the information that follows is additional important information or a tip that will help you recover from an error or point you to related information within the manual.
Patient injury may result from a system malfunction. If a system malfunction occurs, immediately remove unit power (by pulling the battery from the Scan Room Unit), and disconnect the unit from the patient. If a fault message is displayed that cannot be corrected, and/or the system is not operating correctly, do not use the injection system. Call Medrad for assistance. Patient injury could result from leaks or ruptures during an injection. To prevent leaks or ruptures in the event of a blockage, use only catheters and connectors with pressure ratings compatible with this system. Explosion hazard: Do not use the injection system in the presence of flammables (such as anesthetics). Fire hazard: To avoid an electrical fire, assure the correct type of fuse is used for replacement. The fuse must be replaced with Type F, 250 V, 2.5 A fuse by qualified personnel only. Chemical burn hazard: Always carry the battery pack firmly by the battery pack hand grip. Damage to the housing may result in a chemical burn hazard. Do not use if the housing is severely cracked or damaged. Injector performance degradation, image degradation and/or damage to the disposable set may result if the injector is placed too close to the magnet bore. The injector must be placed a minimum of four feet (1.2 meters) from the magnet bore for magnetic resonance imaging scanners having a field strength GREATER than 2.0 Tesla.

1 - Introduction Voltage hazard from worn cabling or unit disassembly: To avoid exposure to potentially hazardous voltages, do not disassemble the injection system in any way. Worn cabling also creates voltage hazards. If any worn or damaged cables are detected, do not use the injection system. Contact Medrad for service or replacement. Improper disposal of the battery pack may result in explosion, leakage, or personal injury. Do not open or incinerate! Follow all local regulations concerning the disposal of spent lead-acid based batteries, or contact Medrad for assistance. System electronic assemblies contain potentially hazardous materials. Dispose of system components or accessories properly. Follow local regulations for proper disposal or contact Medrad Service for assistance. Unsafe operation may result from using improper accessories. Use only accessories and options provided by Medrad designed for this system. The Medrad Spectris Solaris MR Injection System is a dual syringe system. Always ensure that the proper syringes are loaded with contrast media and flush solution prior to the injection. Failure to properly load and install the syringes may require the procedure to be repeated. Syringe A is designated for contrast agent use only. Syringe B is designated for flush solutions only. Injury or equipment damage may result from use of tools containing ferrous materials. Use only non-magnetic tools to install any scanner/ magnet room components. Patient injury and/or catheter damage may result from using connector tubing (LPCT) that is too short. Operator must consider tubing length and stretch limitations when moving the injector or the patient.
Cautions
Condensation may cause electrical damage to the injection system. Do not use the system immediately after it has been brought indoors from extreme outside temperatures. Allow the system to stabilize at room temperature before use. Damage can occur as a result of incorrect voltage. Before plugging in the system, check the following: •
Verify that the voltage and frequency marked on the serial tag on the back of the unit matches the voltage and frequency of the electrical outlet.
•
Verify that the Control Room Unit and the battery charger have the appropriate power cord plugs for the power outlet.
Additional warnings, cautions, and notes are located throughout this manual, where applicable.

2 - System Basics
2 - System Basics About the Injection System
The Medrad Spectris Solaris MR Injection System is a programmable, dual syringe system, designed to accurately administer controlled doses of intravenous MR contrast agents and common flushing solutions to patients undergoing a contrast enhanced MR scan. The system consists of two basic components that communicate by a direct connection of fiber optic lines. •
The Control Room Unit houses the Touch Screen and electronic components used to program the injection system.
•
The Scan Room Unit, positioned near the magnet bore, contains the Injector Head, system battery pack, and the mechanical assemblies required for fluid delivery.
A battery charger is also supplied with the system, used to charge the Scan Room Unit battery pack. For convenience, the charger can be used in the control room, but should never be installed or operated in the scan room.
Note:
Follow all institutional, local, or national safety regulations related to routing cabling on the floor.

Medrad Spectris Solaris MR Injector System
Pressure Safety Limit
The Spectris Solaris MR Injection System is designed to allow varied flow rates for contrast injections. By automatically reducing the flow rate, the system can limit the pressure produced during an injection to prevent damage or failure of any connecting devices or tubing. This feature is called Pressure Safety Limit. Inability to maintain the desired flow rate while remaining below the Pressure Safety Limit can be caused by various conditions including contrast viscosity, catheter sizing, connector tube sizing, and stopcock restrictions. If the system is unable, for a period of three seconds, to maintain a flow rate of at least 10% of the programmed rate, the system will disarm due to a stall condition. If unable to automatically achieve the required level of flow rate reduction, thus reaching the Pressure Safety Limit, the system will terminate the injection and move to a disarm state.
Response to Occlusions
When injecting into an occlusion, a stall condition (flow rate less than 10% of programmed rate) will result. A stall condition lasting more than 3 seconds (3 minutes for programmed rates less than 0.1 ml/sec) will result in the injection being automatically terminated. If an occlusion occurs during KVO (Keep Vein Open) the system will detect the condition after 4 KVO boluses fail to be delivered. This will correspond to from 1 minute with a KVO interval of 15 seconds configured, to 5 minutes with a KVO interval of 75 seconds. Refer to the Setup screen to determine the current KVO setting. If a stall occurs due to an occlusion, and the blockage is subsequently removed, less than 10 ml will be delivered as the pressure in the administration set dissipates.
Volume and Rate Protection
The following means are provided to protect against over and under volume or rate conditions: •
Warnings displayed on the Safety screen and during the arming sequence remind the operator to check the programmed injection parameters prior to the system being armed.
•
An onscreen indication of insufficient volume is provided whenever the total volume programmed to be delivered is greater than the amount of fluid in the syringe.
•
Injection monitoring is performed to detect over rate or over volume conditions due to system faults. If either of these conditions is detected, the injection will be stopped before an additional 10 ml of fluid above programmed volume is delivered.
