1 - 6

1 - Introduction

Electrical shock hazard. Equipment must only be connected to a supply
mains with protective earth.

Ventilation hazard. To avoid a build up of hydrogen gas from the battery,
assure the room is well ventilated while battery is charging.

Improper disposal of the battery pack may result in explosion, leakage,
or personal injury. Do not open, or dispose of in a fire! 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.

Chemical burn hazard. Always carry the battery pack firmly by the battery
pack hand grips. Damage to the housing may result in a chemical burn
hazard. Do not use if the housing is severely cracked or damaged.

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.

The MEDRAD Spectris Solaris EP 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.

Serious injury or death may result from syringe failure. Do not retract
pistons with connector tubing installed. Retracting the pistons with the

connector tubing installed on syringes will create a vacuum in the syringe due
to the check valve in the connector tubing. This vacuum may accelerate the
plunger rapidly toward the tip of the syringe when it is removed from the
injector causing the syringe to break.

About the Injection System

The MEDRAD Spectris Solaris EP MR Injection System is a programmable,
dual syringe system, designed to accurately administer controlled doses of
intra-venous 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.

2 - 9

MEDRAD Spectris Solaris EP MR Injection System

Pressure Safety Limit

Response to Occlusions

The MEDRAD Spectris Solaris EP 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.

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 or less 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.

Volume and Rate Protection

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.

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.

3 - Preparing to Inject

Battery Maintenance WARNING: Explosion Hazard. Serious injury or death may result

from improper use of the battery charger. The battery charger,

MEDRAD Catalog Number 3012424, is intended for use in a well
ventilated area, with the injection system battery, MEDRAD Catalog
Number 3012070, only. Do not use the charger with non-rechargeable
batteries.

When the Main screen appears, check the status of the system battery in the
lower left corner of the screen. The battery icon will contain three horizontal
bars when indicating full charge, two when indicating medium charge, one for
low charge, and no indicators in the icon when the battery is fully depleted,
not connected, or communication is not detected between the Control Room
and Scan Room Units.

If the depleted battery is not replaced when only one bar is displayed, the
system will complete any injection that is in progress. However, the system
may not initiate a single or multi arm injection, the forward and reverse
controls on the injector head may not function and system communications
may be lost.

Each battery pack should last for 4 to 6 typical injections using a 20 minute
KVO, or approximately 5 hours in an idle state before requiring a recharge.
Monitor battery status per injection and on a daily basis. Each battery is
capable of being recharged approximately 300 times. When the life of a
battery pack becomes shortened, noticeably sustaining fewer injections per
charge, this signals that battery life is expiring and the battery pack should be
replaced. Call MEDRAD Service for battery pack replacement.

To charge the battery, place the 3-pronged, charging head into the battery,
then connect the charger to AC power. A green LED on the charger indicates
that AC power is applied. An amber LED indicates that the battery is charging.
The amber LED will turn off when full charge is reached. Battery charge time
is approximately 5 hours.

Retracting the Pistons

Fully retract each piston by using the reverse switches on the injector head.

Note: When using the reverse switches, first press the Enable

switch; then within 5 seconds, press the reverse
switch(es). Both pistons may be reversed simultaneously.

The forward and reverse switches have dual speed capabilities:

When the switches are partially depressed, the pistons will move slowly.
When fully depressed, the pistons will move quickly. Forward and reverse
piston speeds are fully configurable (1 to 10 ml/sec) in the Setup mode.

The manual knobs may also be used to move the pistons in the forward or
reverse direction. Turn the knobs clockwise to advance the piston,
counterclockwise to retract.

3 - 22

Installing a Syringe WARNINGS:

Patient or operator injury may result if damaged components are
used. Do not use damaged components. Visually inspect all

components before use.

Patient infection may result from the use of non-sterile
components. Maintain sterility of all disposable components. Do not

store pre-loaded syringes.

The use of single-use disposable devices on more than one
patient is a biological hazard. Do not reuse single-use disposable

components.

Patient injury could result if the syringe is not properly engaged.
Ensure the alignment marks on the syringe and injector head are
properly aligned, and the piston and plunger are interlocked. Improper
engagement may cause syringe damage or under-volume delivery.

CAUTION: Improperly engaged syringes may leak or be
damaged. Ensure proper engagement of syringe and injector. Syringe

and injector engagement points must align.

3 - Preparing to Inject

Note: Syringe A is intended for contrast media, and Syringe B

is intended for flushing solution only.

1. Align the flanges on the syringe with the notches in the injector head.
(The syringe is keyed to properly fit in only one way.)

2. Insert the syringe.

3. Twist 1/4 turn clockwise until the syringe snaps into place. (Graduations

will be facing the front of the injector head.)

WARNING: Air embolism can cause patient injury or death. Expel
all trapped air from the syringe(s), connectors, tubing, and catheter­over-needle before injecting.

Note: Do not hit or tap the syringe to remove air bubbles.

To reduce the volume and size of air bubbles drawn into the syringe during
loading, a MEDRAD Fluid Dispensing Device (FDD or “spike”) is

recommended. Air removal from the syringe(s) will be much more difficult if a
small diameter tube, such as a catheter-over-needle, needle, or a tube longer
than 10 inches (25 cm), is used for loading.

Operator vigilance and care, coupled with a set procedure, is essential to
minimizing the possibility of an air embolism. The injector head should be

pointed upward during loading, enabling any air to accumulate at the syringe
tip and to be expelled. The injector head should be pointed downward during
an injection, enabling any small air bubbles which could still be in the fluid to
float to the rear of the syringe(s).

To help avoid air injection, MEDRAD syringes are equipped with FluiDot indi­cators. These FluiDot indicators should be observed as part of an arming pro-

cedure. When the FluiDot is viewed through an empty syringe, the dots
appear as small narrow ellipses as illustrated below in figure 1. However,
when viewed through a full syringe, the dots become larger, almost round (or
wider than round) as illustrated below in figure 2.

FluiDot indicators must be viewed in a properly illuminated environment, with
a light source behind the operator providing enough light to permit easy
viewing.

To minimize air embolization risks, ensure that one operator is designated the
responsibility of filling the syringe(s). Do not change operators during the
procedure. If an operator change must occur, ensure that the new operator
verifies that the fluid path is purged of air.

WARNING: If a blockage occurs, disposable components with a
lower pressure rating may leak or rupture. Use only catheter and

connectors with ratings that are compatible with the MEDRAD
Spectris Solaris EP MR Injection System.

During installation of the low pressure connector tubing (LPCT) with T­connector to the syringe(s), and before arming, manually advance the syringe
plunger(s) to provide a very slow flow of fluid at the connection. An absence of
flow is an obvious indication of air or a blockage in the fluid path.

3 - 24

Loading a Syringe WARNIN GS:

1. Position the injector head so that the syringes are

pointing upward.

2. Fully advance each piston plunger. The plungers
may be advanced simultaneously after pressing
ENABLE.

3. Attach a sterile filling device (spike or Female-to­Female Adaptor - MEDRAD Catalog Number FFA

50) onto the tip of the syringe. If loading contrast
media and/or saline from a bag or bottle, use a
spike. If loading contrast media from a pre-filled
syringe, use an FFA 50.

A. If using a spike, open the bottle(s) of contrast
and/or bag(s) of flushing solution, then draw the
contents (contrast for syringe A; flush for syringe B)
into the syringe(s) by depressing ENABLE, and
then the reverse load button for each syringe.

B. If using the FFA 50, attach it to the tip of syringe

A, then attach the pre-filled syringe to the FFA

50. Draw the contents from the prefilled syringe
into syringe A by pressing ENABLE, then the
reverse load button.

4. With the filling device still attached, advance the
plunger to expel any air that may remain in the top
of the syringe; then, if necessary, draw more fluid
into the syringe to replace fluid loss.

5. Remove the filling device and expel any air bubbles
from the syringes.

Remove all trapped air from the syringe, connector tubing, and
catheter-over-needle before connecting the patient to the injector.

Syringe sterility will be compromised, and patient infection may
result, if the plunger is removed from the syringe. Do not remove the
plunger to fill the syringe.

Bacterial contamination can occur if syringes are used to store
contrast media. Use loaded syringes immediately. Do not store loaded
syringes for later use. Discard any unused syringes.

Note: The presence of rounded FluiDot indicators does not

indicate the total absence of air bubbles in the syringe tip.

Note: FluiDot indicators must be viewed in a properly

illuminated environment, with a light source behind the
operator providing enough light to permit easy viewing.

6. Attach the long end of the T-connector to
syringe B.

7. While the injector head is still in a vertical
position, attach the short section of the T­connector to syringe A.

8. Starting with syringe A, then syringe B,
prime the T-connector, then fill the
connector tubing with the appropriate
fluid. Ensure that all air is expelled from
the entire length of the tubing.

Saline Flush Contrast

Note: A MEDRAD SSIT 96VLD low pressure connector tube

(LPCT) holds approximately 7 ml of fluid. If syringe B is
used to flush, use at least 8 ml of flush to deliver this
volume to the patient.

Note: If the connector tube is filled with saline, contrast will be

delivered to the patient with a delay dependent on the
flow rate selected for syringe A.

Note: When the connector tube is filled with contrast the

volume remaining displayed on the protocol screen is
approximately 7 ml less than what was loaded into the
syringe.

9. Tilt the injector head downward before attaching to the vascular entry
device in the patient. After attaching the connector tube to the vascular
entry device verify that the connector luer fittings are secured. The
injector head must be maintained in this position during the injection.

WARNINGS:
Patient injury could result from movement of the Scan Room Unit
after the patient is connected to the fluid path. Lock the casters at

the base of the unit and the Middle Pivot Clamp to prevent unintended
movement.

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.

10. Secure the Scan Room Unit by locking the casters and the Middle Pivot
Clamp, then verify that all air has been expelled from the fluid path by
carefully inspecting all tubing and syringe(s). Acknowledge that the
inspection has occurred by pressing the AIR REMOVED confirmation
button/indicator on the injector head. The Air Removed Indicator will then
illuminate yellow on the touch screen.

Note: Reverse movement of the pistons after the AIR

EXPELLED button has been pressed will cancel the Air
Expelled status. Re-check the fluid path for air, then
press the AIR EXPELLED button again to continue.

piston/plunger interlock.

3. Rotate the syringe 1/4 turn
clockwise until the syringe
locks and alignment marks are
positioned.

4. Proceed as normal by
aspirating and dislodging any
air bubbles.

Reinstalling a Syringe

WARNING: Patient injury could result if the syringe is not
properly engaged. Ensure the alignment marks on the syringe and

injector head are properly aligned, and the piston and plunger are
interlocked. Improper engagement may cause syringe damage or
under-volume delivery.

If you remove a syringe from the injector, and then wish to reinstall it, perform
the following steps:

Note: If bubbles appear in the syringe DO NOT hit the syringe

to remove them. Reverse the plunger 3 to 5 ml, then rock
the head on the pivot to gather and accumulate the small
bubbles. Expel the remaining air.

4 - Arming and Injecting

Before beginning the arming process, ensure that the casters on the Scan
Room Unit are locked, verify that all air has been expelled from the fluid path,
and that the programmed parameters are correct. Carefully inspect all tubing
and syringe(s), then acknowledge that the inspection has occurred by
pressing the AIR EXPELLED button/indicator on the injector head. A yellow
illuminated Air Expelled Indicator on the touch screen confirms that the button
has been pressed.

WARNINGS:
Air embolization can cause death or serious injury to the patient.

Do not connect a patient to the injector until all trapped air has been
cleared from the syringe and fluid path.

Patient injury could result from high flow rate venous injections.
Use extreme care when selecting flow rate and duration. Before
arming the injector, verify that high flow rate injection parameters have
not been unintentionally programmed.

Patient injury could result from inadvertent aspiration. To
minimize the possibility of inadvertent aspiriation and injection, ensure
the patient is disconnected from the injector when utilizing the forward/
reverse plunger control(s).

Extravasation can cause injury to the patient. Follow commonly
accepted good clinical procedures to minimize the possibility of
extravasation.

Arming To begin the arming and injecting process, press ARM on the Main screen. If

necessary, changes can be made to programmed injection parameters after
the arming sequence is complete. Select the required parameter, then enter
the correct value with the on-screen keypad. Pressure safety limit pro­grammed by the user is indicated to the user and cannot be changed when
the injector is armed.

Note: If the AIR EXPELLED button on the injector head has not

been pressed, the system will request user confirmation
that air has been expelled before proceeding.

Single and Multi­Arm

Select either a Single or Multiple arming sequence by pressing either SINGLE
or MULTI. (The default is Single arm.)

A single arm injection will perform the protocol once, then disarm.

A multi-arm injection allows the protocol to be repeated, creating a series of
injections. After the protocol is completed, the system will automatically re­arm in preparation for the protocol to be repeated. Each injection in the series
must be started with the handswitch.

4 - 35

MEDRAD Spectris Solaris EP MR Injection System

Insufficient Volume If an insufficient volume condition occurs during a multi arm sequence, the

system will remain armed to permit the injection of the remaining volume.
However, the screen will update to display only the phases that are
achievable with the volume that remains. In a single arm sequence, the
screen will update when arming occurs to display only the phases that are
achievable.

While the system is armed, pressing DISARM or activating any injector head
controls will return the system to the idle state.

Injecting After the system has been armed, press the handswitch to begin the injection.

Additional presses of the handswitch will alternately “hold” and resume the
injection. The maximum duration for Hold is 20 minutes. If the maximum hold
time is exceeded the injection will abort automatically.

If an inject delay has been programmed, pressing the handswitch will
activate the countdown timer. The programmed injection will automatically
begin when the timer counts down to zero. If the handswitch is pressed during
an inject delay, the countdown timer will stop counting until the switch is
pressed again, or the Hold time is exceeded.

If a scan delay is programmed, the scan delay countdown and the injection
will start simultaneously. During the injection, additional presses of the hand
switch will alternately “hold” and resume the injection and the scan delay
timer.

If KVO is running: KVO will function during Pause, Hold and/or inject delay
periods as long as sufficient fluid remains in syringe B to complete the
programmed injection. KVO will run post-injection until no fluid remains in
syringe B, or until STOP KVO is pressed in the Injection Complete window. To
stop KVO the operator can also press any injector head control buttons.

If a Hold phase is entered, parameters for the remaining portion of the
injection protocol can be altered.

Clean Up Note: Do not resterilize or reuse any disposable items.

When cleaning the injector, remove and discard all used disposable items.
(Syringes should be removed without retracting the pistons.) It is not
necessary to remove the connector tubing when removing and discarding
syringes.

WARNING:
Serious injury may result from syringe failure. Do not retract
pistons with connector tubing installed.

• Disconnect the Control Room Unit from line power and remove
the battery from the Scan Room Unit before cleaning.

• Avoid fluid entry into system components. Do not immerse any
components in water or cleaning solution.

• Do not remove any covers or disassemble the injector.
Periodically inspect for loose or frayed cables, loose covers,
cracks, dents, or loose hardware. Contact MEDRAD Service for
repairs.

• Retracting the pistons with the connector tubing installed on
syringes will create a vacuum in the syringe due to the check
valve in the connector tubing. This vacuum may accelerate the
plunger rapidly toward the tip of the syringe when it is removed
from the injector causing the syringe to break.

CAUTIONS:
System malfunction may be caused by failure to perform regular
maintenance. Regular preventive maintenance is recommended to

ensure that the system stays calibrated and functions properly. Refer
to Appendix B of this manual or contact MEDRAD for additional
information.

Appendix C: Specifications

Classifications Protection Against Electrical Shock: Per IEC/EN 60601-1, the MEDRAD

Spectris Solaris EP MR Injection System is designed as Class 1 equipment

with Type BF applied parts.

Type BF corresponds to the degree of protection against electrical shock via
the applied parts. Class 1 applies to equipment which includes a means for
the connection of the equipment to protective earth in such a way that
accessible metal parts cannot become live in the event of failure of basic
insulation.

Flammable Anesthetics: The MEDRAD Spectris Solaris EP MR Injection
System is not suitable for use in the presence of a flammable anesthetic

mixture with air, oxygen, or nitrous oxide.

Protection Against Ingress of Fluids: Per IEC/EN 60601-1, the Scan Room
and Control Room Units have been classified as drip proof equipment. The
components of the MEDRAD Spectris Solaris EP MR Injection System Scan
Room and Control Room Units are provided with an enclosure that prevents
the entry of such an amount of falling liquid as might interfere with the safe
operation of the injector, indicated by the IPX1 designation. The battery
charger is not classified for protection against the ingress of fluids.

Mode of Operation: Per IEC/EN 60601-1 the mode of operation for the
Control Room Unit is continuous operation. It will operate under normal load
for an unlimited period, without excessive temperature being developed.

The Integrated Continuous Battery Charger power supply will operate under
normal load for an unlimited period, without excessive temperature being
developed.

The mode of operation for the Scan Room Unit is continuous operation with
intermittent loading. Although power is applied to the Scan Room Unit
continuously, intermittent use for loading and injecting will result in an internal
temperature less than continuous load operating temperatures, but greater
than no-load operating temperatures. Under normal operating conditions with
a minimum of 10 minutes between injections, the internal temperature of
the Scan Room Unit will not rise enough to degrade system performance or
reliability.
