Warnings and Cautions
Warnings tell you about dangerous
conditions, that could lead to death or
serious injury to the user or patient, that
can occur if you do not obey all of the
instructions in this manual.
1. WARNING:You should ensure that the
performance offered by the pump is fit for the
intended purpose. Failure to do so may result
in compromised function of the product,
patient injury or user injury.
2. WARNING: Do not use a faulty pump.If the
pump detects a fault when it is first turned on,
or if it develops a fault during operation then a
continuous system alarm sounds.The pump
must be referred to a suitably qualified
technician orreturnedto Graseby Medicalin
order to have the fault rectified.
3. WARNING: Before using the pump,it should be
inspected for physical damage.The pump
should not be used if damage is evident, and
should be returned to service personnel for
repair before being returned to use. Failure to
do so may result in compromised function of
the product,patient injury or user injury.
4. WARNING: Do not use the pump if you detect
any cracks, chips and loose or bent parts, or
if the buttons do not move in and out freely
when they are pressed. Failure to do so could
cause inadvertent disconnection of the pumps.
5. WARNING: Do not push or pull on the pumps,
or the IV pole may tip over or the pumps fall
to the floor. Do not try to remove modular
connected pumps from the IV pole whilst they
are joined together.Either of these could
cause the administration set to separate from
the fluid container thus spilling the
medication, or the pumps themselves could be
damaged.
6. WARNING:Correct entry of data is essential in
order to ensure that the intended infusion is
performed. Before confirming any displayed
data when setting up an infusion, you should
ensure that it is correct. Failure to do so may
result in compromised function of the product,
patient injury or user injury.
7. WARNING: Dose-rate calculation requires
care in entering data. Refer to specific product
drug labelling for information on appropriate
administration techniques and dosages.
Entering incorrect data may result in patient
injury or death.
8. WARNING:When delivering drugs in the
epidural space, use only those medications
specifically indicated for epidural use.
Epidural administration of other drugs could
result in serious patient injury or death.
9. WARNING:The use of administration sets
incorporating injection sites could lead to an
improper or inappropriate infusion resulting in
serious patient injury or death.
10. WARNING:Failure to clearly identify the pump
and administration sets could lead to an
improper or inappropriate infusion resulting in
serious patient injury or death.
11. WARNING: Remove any air to prevent air
embolism.The presence of air within the
infusion can result in complications resulting
in patient injury or death.
12. WARNING: To avoid over infusion,do not
prime the infusion line when the admini-
stration set is connected to the patient. Over
infusion can result in patient injury or death.
13. WARNING:The Occlusion alarm level must be
checked before starting an infusion to ensure
that it is appropriate for the infusion. Failure
to do so may result in an unacceptably slow
time to Occlusion alarm, resulting in patient
injury or death.
14. WARNING:Prior to starting an infusion,
inspect the fluid path for kinks, a closed clamp
or other obstructions. Failure to do so may
result in the infusion not being delivered
correctly, resulting in patient injury or death.
15. WARNING:If using a blood pressure cuff above
the patient’s venipuncture site take extra care
in setting the Occlusion alarm pressures.
Failure to do so may result in unnecessary
Occlusion alarms, resulting in patient injury
or death.
16. WARNING:The Occlusion detection system
measures downline pressure in the admini-
stration set, but does not detect infiltration. In
accordance with local protocol, you must
periodically inspect the patient’s infusion site
for signs of infiltration. Failure to do so may
result in an unacceptably slow time to
Occlusion resulting in patient injury or death.
17. WARNING:If an Occlusion alarm occurs,
immediately clamp the line to the patient.Then
inspect the fluid pathway to determine what
has caused the obstruction. An unintentional
bolus of medication can result in patient injury
or death.
Warnings

Volumetric Infusion Pumps
Warnings and Cautions
Graseby Medical Ltd.
18. WARNING:Do not run parallel infusion lines
below the pump. Delivering a Secondary
infusion means running a second line
above
the pump. Failure to do so may result in an
inaccurate delivery of medication, resulting in
patient injury or death.
19. WARNING:Check the Secondary set carefully,
since an occlusion above the pump on the
Secondary line could cause the Primary fluid
to be delivered instead of the Secondary
infusion. Administering the wrong medication
may cause serious patient injury or death.
20. WARNING:The Secondary volume to be infused
must match the amount of fluid in the
secondary container.Primary flow resumes
when the secondary container is empty. If the
volumes do not correspond, the wrong infusion
may be delivered which could cause serious
patient injury or death.
21. WARNING: Correct management of battery
charging, as described in this documentation
is essential to ensure that the pump can
operate on battery for the time specified.
Failure to do so may result in compromised
function of the product or patient injury.
22. WARNING:If a backup alarm sounds,the pump
should be immediately removed from the
patient and sent to be repaired by a Graseby
Medical qualified technician. Failure to do so
may cause patient injury or death.
23. WARNING:Failure to use the power cord
retainer means that the pump may be
accidentally or erroneously disconnected from
the mains. Although there is a battery backup
in case this happens, the battery may not be
charged sufficiently.Consequently, there is a
risk of the pump not functioning which could
lead to patient injury or death.
24. WARNING:Donot open thepump housing.
Refer all service faults only to qualified
technical personnel. Opening the pump
housing may cause electric shock leading to
patient or user injury or death.
25. WARNING:When the pump is carrying out an
infusion, to ensure that electrical safety is
maintained, only items of equipment that
conform to EN60950 are to be connected to the
RS232 connector situated at the back of the
pump, otherwise patient safety may be
compromised.
26. WARNING:While Graseby Medical Limited
have taken all reasonable steps to ensure that
the pump operates correctly while under
remote control, it is the responsibility of the
person who designs and implements the
controlling device to ensure that the resulting
system (pump and controlling device) is fit for
its intended purpose. Failure to do so may
result in compromised function of the product,
patient injury or user injury.
27. WARNING:Use only Graseby Medical
administration sets with this product. Failure
to do so may result in compromised system
accuracy leading to complications resulting in
patient injury or death.

Contents
The information in this section is
intended for technicians and clinicians
already familiar with earlier versions
of the Graseby 500/505 volumetric
pump. It summarises the changes to
the pump that appear with version 0.71
of the pump software:
• new menu,
• new options,
• new features that the menu and
options provide.
To find out the software version of a
particular pump, check the instructions
label on the right side of the pump. If
there are more than eight options
listed, then the software version is 0.71
or later.
For full details on how to use the pump
see the VolumetricInstruction Manual.
For information on configuring the
pump, see the Technical User Manual,
and for more detailed technical
information, obtain a copy of the
VolumetricServiceManual.
New Menu
A Technician Menu has been introduced,
to simplify the configuration of each
pump. Some of the items on the
Technician Menu affect how the pump
behaves; others control the options that
appear to the pump user when they
press the Options button to show the
Options menu. The configurable items
on the new Technician Menu are shown
on page 12 of the Technical User
Manual.
If the Technician Menu settings are left
at their factory defaults, the pump
behaves as the previous version of the
pump.
New features of version 0.71 software
New Options
The new options (and some of the
previous options) can be enabled on the
Technician Menu. This means that they
can appear when appropriate, but can
be disabled if not required. On the
instruction label on the pump, Options
numbered 1 to 8 are the ones that
appeared in previous versions of the
pump software. The additional new
options shown on the label are:
• Primary infusion Minimum
• Primary infusion Maximum
• Primary Max Volume to be infused
• Secondary/Bolus Minimum
• Secondary/Bolus Maximum
• Secondary/Bolus Max Volume to be
infused
• KVO Rate
• Drug Library to allow selection and
display of a drug label.
New features
The new menu and new options in
version 0.71 software provide a number
of new features. These fall into the
following broad areas:
• Infusion mode features
• Safety features
• Display features
• Servicing features.
Infusion mode features
Using the Technician Menu, the pump
can be configured:
• to stop at the end of a Secondary
infusion, or to continue infusing and
automatically switch to the
programmed Primary rate;

vi
Volumetric Infusion Pump Instruction Manual
Contents Graseby Medical Ltd.
• to allow a Bolus infusion to be
programmed where the volume
infused is deducted from the
primary infusion volume to be
infused; to highlight this feature,
the key previously called
“Secondary” is now called
“Secondary/Bolus”
• to allow the user to set a KVO rate
for an infusion, or remain at the
default rate configured for the
particular pump;
• to use the Occlusion Alarm level
specified for an infusion, or remain
at the configured default alarm
level;
• to allow access to a previously
programmed Dose-Rate Calculation
infusion when the pump is switched
on (Dose-Rate Calculation recovery),
or display the standard messages.
Safetyfeatures
• a timeout safety feature has been
added. This means that when
messages are not actioned within
the timeout period, for example
setting a value, the pump reverts to
the previous display.
• safety keypad lockout, this feature
is only activated when operating the
pump on AC power. It allows the
user to lockout the keypad after
setting the pump up for use, so that
it can be ready for infusion at a
later time.
Configurable safety features that can be
controlledon the Technician Menuare:
• automatic keypad lock after one
minute, to prevent malicious
tampering, and increase patient
safety;
• preset rate and VTBI limits, so that
Infusion Rate and Volume to be
Infused are limited to a suitable
range; this prevents values being
programmed accidentally which are
inappropriate for infusions in
particular environments (such as
epidural infusions, or paediatric
applications).
Displayfeatures
• configured parameters are shown on
the Message Display when the pump
is switched on.
Configurable display features that can be
controlledontheTechnicianMenuare:
• the backlight may be activated when
the keypad is touched, or kept on
permanently;
• one of 30 preset drug labels may be
selected and viewed as required
during an infusion;
• the display of micrograms (when
programming an infusion using
dose-rate calculation) can be shown
as ‘µg’ or ‘mcg’;
• the time display may include the
suffix GMT, or the suffix can be
suppressed if it is not appropriate.
Servicingfeatures
On the Technician Menu, the pump can
be programmed with a pump ID to suit
the hospital protocol, and a service due
date:
• the ID, for example the serial
number of the pump, or an
alphanumeric pump name, is
displayed each time the pump is
turned on;
• when a Service Date is set, the date
is displayed each time the pump is
switched on. An alarm sounds when
the date is reached.

Introduction
Introduction to the 500/505 pumps
The Model 500 is designed for use in all
areas, as it can be programmed with an
infusion rate of up to 999 millilitres per
hour, and a maximum volume to be
infused of 9999 millilitres.
The Graseby Medical 500 and 505
Volumetric pumps are designed for use
in infusion therapy in both venous and
arterial infusions. They offer both
standard and optional features
bringing accurate fluid delivery to the
patient.
This makes them ideal for use in
general care, home care, and intensive/
critical care areas.
The Model 500 and Micro 505 pumps
are very similar in design. The
differences are in colour, graphics and
in the maximum rate and volume to be
infused that can be programmed for an
infusion.

Volumetric Infusion Pump Instruction Manual
Introduction
Graseby Medical Ltd.
Both the Model 500 and the Micro
505 pumps may be used for epidural
administration.
Anaesthetics
Epidural administration of
anaesthetics is limited to short-term
(not to exceed 96 hours) infusion, with
indwelling catheters specifically
indicated for short-term delivery of
anaesthetic drugs.
Analgesics
Epidural administration of analgesics
is limited to use with indwelling
catheters that are specifically indicated
for short or long term delivery of
analgesic drugs.
Epidural administration
To prevent infusion of drugs not
indicated for epidural use and to avoid
inappropriate delivery rates when
using the pump for epidural
applications:
• use the pump’s Maximum Rate
option, to set a maximum infusion
rate of 20 mL/h on a pump to be
used for epidural administration.
This feature is described fully in
Chapter 3, Options;
• do not use IV administration sets
which contain injection sites;
• differentiate the pump and IV set
being used for epidural delivery from
those being used for other routes of
administration. A yellow Epidural
Label Set for the Volumetric
Infusion Pump (part number TPF-
00306) is available from Graseby
Medical. The labels should be stuck
on the front, top and sides of the
pump to help staff to identify a
pump that is dedicated to epidural
application.
WARNING: The use of administration sets
incorporating injection sites could lead to
an improper or inappropriate infusion
resulting in serious patient injury or
death.
WARNING: Failure to clearly identify the
pump and administration sets could lead
to an improper or inappropriate infusion
resulting in serious patient injury or
death.
WARNING: When delivering drugs in the
epidural space, use only those
medications specifically indicated for
epidural use. Epidural administration of
other drugs could result in serious patient
injury or death.

Introduction
Pump features
The main features of the 500 and 505
pumps are listed below:
Easy to use features
The pumps have been designed to be
easy to use:
• they are easy to set up and operate,
yet with all the advanced features
typically associated with the more
complicated infusion systems;
• they have a straightforward keypad
and an easy-to-read message display;
• the unique air-in-line removal
system allows clearing of bubbles in
the line by simply opening and
closing the door: air is prevented
from going beyond the cassette; this
increases patient safety, minimises
the risk of infection and saves
operator time;
• they can be used at the bedside or as
transportable equipment; using the
internal battery which also switches
in automatically if the pump is
being used on mains power and this
is interrupted.
Use of administration sets
The pumps can only be used with
Graseby Medical administration sets.
These administration sets have the
following features:
• all Graseby Medical administration
sets incorporate a safety clip to
prevent accidental free flow when
the administration set is removed
from the pump;
• when used with Graseby Medical
blood administration sets the
pumps deliver blood and blood
products without significant
haemolysis of red blood cells.
Infusion mode features
• accurate (± 2%) fluid delivery;
• the pumps can be configured to stop
at the end of a Secondary infusion,
or automatically switch to infuse at
the programmed Primary rate;
• a Bolus infusion may be
programmed so that the volume
infused is deducted from the
primary infusion volume to be
infused;
• KVO rate may be specified for an
infusion, or remain at the default
rate for a particular pump;
• the pumps offer a quick rate change
feature for complete titration
capability;
• automatic delivery of a secondary
medication (if a secondary infusion
has been set up).
Safetyfeatures
The pumps have been designed with a
high emphasis on safety:
• there is an optional automatic
keypad lock which prevents
inadvertent operation and increases
patient safety;
• the keypad can also be locked
manually at any time;
• a pump may be configured so that
its Infusion Rate and Volume to be
Infused are limited to a suitable
range; this prevents values being
entered accidentally which are
inappropriate for infusions in
particular environments (such as
epidural infusions).
• the pumps have indicators that are
lit to show if they are running on
battery or mains;

1 — 4

Introduction
Graseby Medical Ltd.
• when using the battery, a test is
performed on power-up and the level
is shown on the display; manual
testing is also available;
• the pumps have an RS232 interface
allowing connection to a computer
for external monitoring.
Displayfeatures
Apart from the standard display,
pumps can be configured to show extra
information, either as a standard
message display or by pressing a key to
toggle the display.
Standard displays are:
• the volume infused in the current
infusion;
• the infusion rate;
• the Volume to be Infused in the
remainder of the infusion.
Additionally:
• the rate and volume to be infused
displays are automatically adjusted
to make them easy to read in any
light;
• the time remaining in the present
infusion may be viewed;
• the total volume of fluid delivered to
your patient since the totaliser was
last cleared to be viewed; also
displayed with the total volume is
the total time (hours and minutes)
that the pump has been in use since
the totaliser was last cleared;
Using configurable displays:
• the backlight may be activated when
the keypad is touched, or kept on
permanently;
• optionally, one of 30 preset drug
labels may be selected and viewed
as required during an infusion.
OcclusionPressure features
These features increase safety in
infusing fluid, particularly in critical
care areas such as neonatal and
paediatric care:
• when setting occlusion alarms, three
standard occlusion alarm settings
between 100 and 500 mmHg can be
made; see the Specification section
at the end of this manual for full
details of the occlusion alarm
values;
• the occlusion pressure alarm setting
when the pump switches on is
configurable; you can change the
setting for a particular infusion
using the Occlusion Alarm
Setting key;
• when an occlusion alarm sounds, the
pumping mechanism backs off to
reduce downline back pressure and
bolus potential (bolus potential is
approximately 0.3 mL regardless of
the rate and the administration set
used);
• when an occlusion is detected, the
pump does not give an occlusion
alarm immediately, but only alarms
if the occlusion pressure continues
to exceed the occlusion threshold for
up to 10 seconds; however, if such
temporary occlusions persist, then
the occlusion alarm is generated;
this helps to avoid nuisance
occlusions.

Introduction
Special infusion features
The pumps have a number of special
infusion options:
• a Volume over time option allows
the user to set the volume to be
infused and total time for the
infusion, the pump automatically
calculating the infusion rate;
• a Dose-rate calculation option which
allows automatic calculation of the
infusion rate by entering infusion
dose; patient weight (kg or lbs); drug
amount in fluid container (in MG,
Gm or mcg units), and volume of
fluid in the container, in mL;
• a Rate Tapering option allows
automatic tapering of the infusion
rate (either up or down) for
administration of IV nutrition.
Multiple use features
When multiple infusion lines are
required, two or three pumps can be
fitted together:
• modular side rails and hooks mean
that one, two, or three pumps may
be connected to a single IV pole; this
provides space saving;
• the modular connection system has
a safety feature which ensures that
the first pump must be correctly
attached to an IV pole before the
second and third pumps can be
connected.
Servicingfeatures
The pumps have been designed with a
number of features for Biomedical
engineers:
•a Service Due Indicator, allows a
service date to be set, which is
displayed on power-up with an
alarm;
• special menus are provided to aid in
testing, troubleshooting and service;
• the last 200 events are recorded and
available on these menus;
• downloading of the pump history is
possible using the RS232 port with
a special optional kit (Part no 0150-
0673).
Together with the ability to configure
the pump using the Technician Menu,
these features offers greater
management flexibility.
Instructions for using these functions
appear in the Technical User Guide and
the Volumetric Service Manual.
Optionalfeatures
Some pumps are optionally fitted with
a Nurse-Call Feature which allows a
pump to be connected to a hospital
nurse call system and signal alarms
occurring in the pump.
Note: This feature is not available in
all countries.

Operating the pump
What this chapter covers
This chapter introduces the Volumetric
pump. It explains all the terminology
that you should understand, and the
techniques that you use to operate the
pump.
Introduction
These sections describe physical
aspects of the Volumetric:
• front of the pump - indicators and
displays
• front of the pump - programming
keys
• rear of the pump
• attaching the pump to an IV pole
• switching the pump on and off
• using the pump on battery
• sounds on the pump.
These sections explain how to program
an infusion:
• types of infusion
• setting up a Primary infusion
• about Secondary infusions
• running a Bolus infusion.
This chapter does not cover the types of
infusion that may be run if the pump
has optional features enabled. These
are described in Chapter 3, Options.
Who should read this chapter
This chapter is aimed at all users who
have been trained in how to use the
Volumetric pump.
It is not designed to be used as a self-
teach manual, but should be used to
reinforce the best-practice techniques
demonstrated during training sessions.
