Introduction
Graseby Medical Ltd. Introduction to the Omnifuse pump
Introduction to the Omnifuse pump
The Omnifuse is part of the wide range of
Graseby pumps. Omnifuse syringe
pumps have been designed to meet the
growing needs of the clinical
environment. They are suitable for the
administration of drugs or other
parenteral fluids by or under the
supervision of healthcare professionals
such as physicians and nurses.
Omnifuse pump features
The features on the Omnifuse pump can
be tailored to suit individual hospital and
clinical requirements.
The pump offers a Continuous infusion
mode as well as other modes for
specialised infusions: Preset Volume,
Preset Time, Intermittent and Circadian
Rhythm.
The clear messages on the screen guide
you through an intuitive programming
and running sequence, with further
information available from on-screen
help explaining how to use a feature or
follow a prompt. The Omnifuse pump can
be run directly from the AC mains supply
or, when necessary, from its own
rechargeable backup batteries.
The pump has been designed to be simple
to use. Most actions are performed by
choosing options from the screen with
the Command wheel which you turn and
then press. There is a keypad for entry of
numerical data, for stopping and starting
the pump and for switching it on and off.
Carefully read the entire contents of
this manual before using the pump.
This Instruction Manual describes the
features of the standard Omnifuse pump,
explains how to use the pump and also
describes the pump variants.
The pump has a green Command wheel,
LCD surround and keypad.
Safety and security
Many safety features have been
incorporated into the Omnifuse pump:
• Self-test routines run each time the
pump is switched on to check it is
working correctly.
• Continual checks are also made
while the pump is running,
especially during an infusion.
• A wide range of audible and visual
alarms and warnings, including the
LCD screen flashing.
• Each infusion setting must be
reviewed and confirmed before an
infusion can start.
• Occlusion pressure is monitored as a
standard feature. The dry-side
pressure level is displayed while the
pump is running. The occlusion
alarm level setting is adjustable but
may be locked to restrict the upper
level if required.
• A history of 3000 of the pump’s most
recent events or actions, stamped
with their date and time can be
viewed on the pump screen, or
transferred to a PC.
Introduction
Omnifuse Instruction Manual 1 – 1
Introduction to the Omnifuse pump Graseby Medical Ltd.
User interface
The screen and controls on the pump are
easy to use.
• All the information for programming
and running infusions is shown on
the LCD screen (Liquid Crystal
Display).
• Next to the screen is a multi-function
Command wheel which you turn and
Introduction
press to select items and enter
information.
• The pump has a numeric keypad for
entry of data such as bolus dose.
• An Infusion LED flashes to show
that the pump is infusing and
changes colour if the syringe nears
empty. A yellow LED is lit when the
pump is connected to the AC mains
supply.
• While you program the pump and
during an infusion, the screen shows
instructions on a message line. Help
and information icons lead to more
detailed information.
• Status icons show the battery level
and occlusion pressure level.
• A special feature lets you program
the pump ready for an infusion, then
leave it ‘asleep’ until it is needed.
• The pump totaliser shows totals for
the infusion and totals since last
reset. A shift totals feature is also
available.
Administration sets
Graseby medical have a wide range of
Flo-Safer administration sets that may
be used for specific infusion therapies.
These are listed in the Specification at
the end of this manual.
Pump configuration
The features required for a particular
clinical application must be configured
on the pump, by a qualified technician,
prior to use in the clinical area.
The technician uses Graseby Omnifuse
Technician PC software to enable
features on the Configuration menu,
then transfers this information to the
pump. Alternatively, the technician
accesses the Configuration menu directly
on the pump, using a special password.
Once the Omnifuse has been configured
for use, it can be programmed with
specific infusion settings according to the
clinical requirements of the patient and
medication.
In addition to the Configuration menu,
there is a Technician menu giving access
to information about the use of the pump.
This menu is normally accessed using PC
software but may be accessed directly on
the pump, using a special technician’s
password. For more details about
Configuration and Technician menus,
read the Omnifuse Technical User
Manual.
Syringes
On the Omnifuse, the syringe can be
loaded as a one-handed operation.
Syringes of 2 to 60 ml capacity can be
used with the pump.
The syringe type and size are confirmed
as the first step in programming an
infusion. The syringe types that are
available on the pump’s menu depend on
which have been configured for use.
1 – 2 Omnifuse Instruction Manual
Graseby Medical Ltd. Introduction to the Omnifuse pump
Bolus features
The Omnifuse pump may be configured
to offer one or two methods for
administering a bolus: a hands-on and/or
a pre-set bolus. The maximum bolus rate
can be set up to 800 ml/h although this
also depends on how the pump has been
set up and the size of syringe in use.
If no bolus is needed for the clinical area,
then the bolus feature can be turned off.
Mass Units
A wide range of mass units can be
configured for use on the Omnifuse. The
pump can be programmed to give a dose
of medication which is expressed as a
mass unit, rather than volume to be
infused over a period of time.
Protocols
The pump can offer the clinical user a
selection of protocols. Before the pump is
used, the hospital/community protocols
relevant to the clinical area must be
loaded into the pump. This is done using
the Omnifuse Drug Protocol
Management System.
Power
The Omnifuse is normally run from the
AC mains supply. However, it switches
automatically to internal rechargeable
batteries in the event of a power cut or if
it is disconnected from the mains.
On fully charged batteries, the pump
may be run for up to 10 hours depending
on the infusion rate.
External communications
The pump has an RS232 serial cable
connector with PC interface protocol.
This is used for configuring the pump
from a PC, is used to transfer the pump
hi sto ry to a PC and is also used to control
the pump externally.
Introduction
With Protocols in use, all the user in the
clinical area needs to do to set up the
pump for a patient is to load the syringe,
select the protocol and confirm the
parameters displayed on the screen.
Graphics
This feature allows you to view the
progress of the infusion in graphic form
as an infusion profile.
Omnifuse Instruction Manual 1 – 3
Introduction to the Omnifuse pump Graseby Medical Ltd.
Omnifuse pump variants
The standard Omnifuse has no In-line
occlusion sensing capability or Lockable
cover. Three Omnifuse pump variants
are available for use in environments
where In-line Occlusion Sensing or a
Lockable cover are required.
The variants can be specified when the
pump is purchased, or the standard
pump can be upgraded to one of the
Introduction
variants, if it is returned to Graseby
Medical. The three variants are:
• Omnifuse with In-line Occlusion
Sensing
• Omnifuse with Lockable Cover
• Omnifuse with In-line Occlusion
Sensing and Lockable Cover.
In-line Occlusion Sensing
For clinical applications where occlusion
pressure needs to be monitored very
precisely, for example in a Neonatal unit,
the pump should be ordered with an inline occlusion sensor.
This is used with a special extension set,
which includes a pressure sensing disc,
to monitor occlusion pressure in the
infusion line while the pump is infusing.
Lockable Cover
The Lockable cover pump variant may be
used in clinical areas where it is
necessary to prevent the syringe from
being removed and to prevent any
change to the flow rate for the infusion.
The Lockable cover prevents physical
access to the syringe except by an
authorised person with a key. The cover
can be used with the Omnifuse’s Security
software enabled, which locks the
keypad once the infusion is started. This
prevents accidental changes to the
infusion rate, or access to the bolus
feature.
In-line Occlusion Sensing and
Lockable Cover
The Omnifuse is also available as a
pump fitted with both the In-line sensor
and the Lockable cover.
If required, an infusion can be started
without the in-line sensor, in which case

Using the pump on batteries
In everyday use, the Omnifuse pump
should be connected to a suitable AC
mains supply, not used on batteries.
This way, the batteries are kept fully
charged, available for use in an
emergency.
• The yellow Mains LED is only lit
when the pump is connected to the
AC mains supply
• The battery icon P is shown on the
screen when the pump is running on
batteries
• The battery icon is displayed when
the pump is connected to the AC
mains supply, to show that the
batteries are being charged. When
Basics
the batteries are charged, the icon
disappears.
Pump with patient in transit
If a mains supply is unavailable - for
example, if the pump is infusing a
patient in transit - you can start or
continue an infusion with the pump
running on batteries.
Mains lead retainer
The mains lead is held in the pump with
a retainer. This is so that it cannot be
pulled out accidentally.
CAUTION: Failure to use the mains lead
retainer means that the pump may be
accidentally disconnected from the AC
mains supply.
WARNING: Failure to use the mains lead
supplied with the pump will compromise the
pump’s ability to resist fluid ingress,
resulting in possible user or patient injury o
death.
Mains supply failure
If the AC mains supply fails or if the
pump is disconnected from the mains, it
automatically switches to its internal
batteries.
If the pump is infusing, the infusion
continues without interruption. This
message is displayed:
• The yellow Mains LED goes out and
the battery icon P is shown on the
screen when the pump is running on
batteries.
The pump will display a warning
message approximately 30 minutes
before battery power runs out.
When the pump is reconnected to the
main supply, or mains power resumes,
the pump automatically switches back to
the AC mains supply.
Note: When the pump is being used
on battery, an independent battery
monitor is active. This provides an
additional check on the battery
condition.
If the pump’s alarm sounds but no
message is displayed on the screen,
the independent battery monitor has
detected a problem.
The alarm cannot be silenced and the
pump cannot be used. It must be
taken to a qualified technician for
repair.
2 – 6 Omnifuse Instruction Manual
Graseby Medical Ltd. Switching the pump on and off
Recharging the batteries
While the pump is switched off, you
should leave it connected to the AC
mains supply so that the batteries are
always kept fully charged.
Recharging can take up to 10 hours if the
batteries are completely flat.
While the pump is running on the mains
supply, the battery icon P is displayed to
show that the batteries are being
charged. The battery icon disappears
once the batteries are fully charged.
Battery life
As a rough guide, an Omnifuse pump can
operate on battery power for up to 10
hours at a continuous infusion rate of
5 ml/h with the batteries starting from
fully charged. This period includes four
syringe load/unload cycles.
To ensure that the batteries perform as
specified they must always be fully
charged. The batteries must not be left
partially charged for extended periods,
for example when the pump is in store.
WARNING: Correct management of battery
charging is essential to ensure that the
pump can operate on batteries for the time
specified. Failure to do so may lead to
impaired functioning of the pump, resulting
in patient injury or death.

Loading and unloading a syringe Graseby Medical Ltd.
Loading and unloading a syringe
The pump is designed to make loading a
syringe a one-handed operation. There
are three components that secure the
syringe:
• The syringe ear slot
• The barrel clamp
• The pusher.
The syringe is placed in the trough at the
front of the pump. The ear or flange of
the syringe should be placed into the
syringe ear slot. The barrel clamp is
lowered by hand onto the syringe.
The sections on the following pages
provide full details on loading/unloading
a syringe.
