Operator’s Manual
the model and size loaded onto the pump. Use of
unapproved syringes may cause improper pump
operation resulting in inaccurate fluid delivery or
occlusion sensing or other potential hazards.
• Verify that the plunger holders securely capture the
syringe plunger. Make sure to capture the syringe
barrel and flange. Failure to properly secure the
syringe could result in uncontrolled fluid flow to
the patient.
• Always use the
Prime
function on the pump when
loading a new syringe in order to remove any
mechanical slack. Failure to prime correctly can
delay infusion delivery and cause
Total Volume
Delivered
to read higher than the amount actually
delivered to the patient.
• Periodically check the fluid pathway and all
connections (including the catheter/administration
set connection) for leaks. Leaks in the system may
cause fluid loss resulting in under-delivery, as well
as allowing an opening for contamination.
• Always turn off fluid flow to patient in tubing via
clamp or stopcock before loading or unloading a
syringe. Uncontrolled fluid flow can occur when
infusion set is not clamped or turned off resulting
in inappropriate delivery rate.
•
NEVER
prime any syringe while connected to
a patient infusion site, as this may cause over-
infusion.
• To avoid air embolism, always purge all air from
syringe and infusion lines
before
connecting to the
patient.
• Once the syringe and tubing system is connected
to the patient, raising the system above the patient
(even briefly) can cause significant bolusing due
to changes in hydrostatic pressure. Lowering the
system below the patient (even briefly) can cause
significant interruptions in flow due to changes in
hydrostatic pressure. This could cause improper
pump operation resulting in inaccurate fluid
delivery. Place the pump as close to the patient’s
infusion site as possible.
• Use the smallest syringe size necessary to deliver
the fluid or medication. Using a large syringe at
very low rates (below Minimum Recommended
Rate for the syringe) may cause improper pump
operation, delayed occlusion sensing, larger post
occlusion bolus at higher occlusion limit settings,
delivery inaccuracies, or other potential hazards.
Bolus Volume:
Delivering a bolus volume less than
the recommended bolus volume for the syringe
used may result in delivery inaccuracies. Use an
infusion set with the smallest diameter tubing
available that does not result in excessive back
pressure at the desired flow rate. Consider priming,
loading, bolus, and flush rates when selecting an
infusion set.
• Larger size syringes at occlusion setting HIGH may
produce a post occlusion bolus larger than 0.3 mL
due to excessive syringe plunger tip compliance.
• When using Quick Libraries, preset values are
automatically inserted without pausing to verify
each setting. The
Begin Infusion
screen displays
immediately after selecting/confirming the drug
program. Verify the infusion parameters before
starting the delivery. Certain data fields may not be
programmed (e.g. patient weight) and require data
entry before the infusion will proceed.
• If a system failure alarm occurs and cannot be
cleared by powering the pump down then back
up, the pump cannot be used. Remove it from use
and send it to a trained biomedical technician for
service.
• Any external power source connected to the DC
jack must be
IEC 60601-1 certified
for medical
equipment
Type CF
and meet
Safety Class II
requirements. Connecting any external power
source to the Medfusion
®
Model 3500 pump V6
creates a medical device system. Therefore, the user
is responsible for compliance with
IEC 60601-1
standards (see Technical Specifications section for
DC power input function).
•
Electric Shock hazard
. The only means of removing
AC power is to disconnect the AC power cord.
While the AC power cord is attached to the pump
and plugged into an AC outlet, live mains voltage
is present inside the pump.
• Ensure that the ± 2% accuracy specification (±
syringe accuracy) is taken into account when
programming the pump and/or filling a syringe.
If accuracy is of prime concern, use only syringes
that meet the ± 2% requirement of the ISO 7886-2
Standard. Failure to do so may result in medication
in the syringe becoming depleted sooner or later
than expected.
