1.Introduction
About this ManualThis manual is your introduction to the Flowtron
ACS900 system.
You must read and fully understand this manual
before using the system.
Use this manual to initially set up the system, and
keep it as a reference for day-to-day routines and as
a guide to maintenance.
If you have any difficulties in setting-up or using the
Flowtron ACS900 system, contact your local Arjo
sales office, listed at the end of this manual.
Intended UseThe intended use of this product is to help prevent
Deep Vein Thrombosis (DVT). The garments are
single patient use - do not re-use. It is not for use
in the home healthcare environment.
The Flowtron ACS900 system should be used as
part of a prescribed plan of care (refer to “Indications”
on page 3).
About the Flowtron
ACS900 System
The application of external pneumatic compression
has two effects:
• Enhances fibrinolytic activity to reduce the risk of
early clot formation.
The system is comprised of a pump that can be used
in conjunction with an extensive range of Arjo
inflatable uniform (DVT), sequential (Tri Pulse) and
foot garments. Refer to “Accessories” on page 28 for
a complete list of the calf, calf & thigh and foot
garments which can be used with the Flowtron
ACS900 pump.
The pump automatically adjusts to the correct
therapy profile depending upon which garment type
is connected.
The tubeset is integral to the system and cannot be
disconnected from the pump.
The mains power supply is the primary power source
for the pump. The pump incorporates an internal
battery, which is a secondary power source to back
up the pump in the event of failure of or disconnection
from (accidental or deliberate) the mains power
supply.
The Flowtron ACS900 system is intended for use
ONLY in professional healthcare facilities. It is
not intended for use in the home healthcare
environment (for example private dwellings).

2.Clinical Applications
IndicationsThe intended use of the Flowtron ACS900 system is
to help prevent Deep Vein Thrombosis (DVT).
The system should be combined with an
individualised monitoring programme.
This system represents one aspect of a DVT
strategy; if the patient's condition changes, the
overall therapy regimen should be reviewed by the
prescribing clinician.
The above are guidelines only and should not
replace clinical judgement.
Depending on the garment type used, other clinical
applications are also appropriate.
The foot garment, in particular, has a wide range of
clinical applications.
Full details for clinical applications are included in the
packaging of every garment.
The type of garment used on an individual patient
must be specified by a physician.
Contraindications
Uniform & Sequential
Calf and Calf & Thigh
Garments
Foot GarmentsThe system, when used with the foot garments,
The system, when used with calf or calf & thigh
garments, should not be used in the following
conditions:
1.Severe arteriosclerosis or other ischemic
vascular diseases.
2.Severe congestive cardiac failure or any
condition where an increase of fluid to the heart
may be detrimental.
3.Known or suspected acute deep vein
thrombosis, thrombophlebitis or pulmonary
embolism.
4.Any local condition in which the garments would
interfere, including:
• Gangrene
• Recent skin graft
• Dermatitis
• On untreated, infected leg wounds.
should not be used in the following conditions:
1.Severe congestive cardiac failure or any
condition where an increase of fluid to the heart
may be detrimental.
3
Page 10
2.Known or suspected acute deep vein
thrombosis, thrombophlebitis or pulmonary
embolism.
3.Any local condition in which the garments would
interfere, including:
• Gangrene
• Recent skin graft
•Dermatitis
• On untreated, infected leg wounds
If you are unsure of any contraindications refer to
the patient’s physician before using the device.
Cautions1.Proper garment application and connection to
the pump is essential.
2.Garments should be positioned in such a way
that they do not create any potential for constant
pressure points on the patient's limb. If using
apparatus with straps or securing devices, for
example lithotomy stirrups, make sure that the
tubing is not placed inside the strap next to the
patient’s skin, and regularly check the patient's
skin for signs of redness or pressure points. The
garment is most effective in preventing venous
stasis when the garment air bladders are located
in the posterior position. If the air bladders
cannot be placed at the posterior, the garment
can be rotated around the calf to alternative
positions all of which will still help to prevent
venous stasis.
3.Lower limb positioning in relation to the garment
and tubing should also be considered
particularly in a patient that is unconscious,
cannot feel or has reduced sensation and/or
ability to move their leg(s).
4.The patient’s skin should be inspected frequently
during every shift.
Many patients are at risk for pressure ulcers on
the heel. Use of the foot garments does not
negate the necessity for heel protection and
appropriate skin care.
5.Clinical judgement is required to determine if the
patient's skin condition requires additional
protective measures, or if the therapy should be
discontinued and an alternative modality used.
6.Garments should be removed immediately if the
patient experiences tingling, numbness, or pain,
and the physician notified.
4
Page 11
7.When used for DVT prevention, continuous
external pneumatic compression is
recommended until the patient is fully
ambulatory. Uninterrupted use of the system is
encouraged.
8.The system should be USED WITH CAUTION
on patients with:
• Insensitive extremities.
• Diabetes.
• Impaired circulation.
• Fragile or impaired skin.
These are guidelines only and should not replace
clinical judgement and experience.
Guidelines and Recommendations
General
Recommendations
• The system should be initiated immediately once
the risk of DVT formation is identified and the plan
of care has been prescribed.
• If compression stockings are ordered by the
physician, the clinician should ensure that the
compression stockings are properly measured,
applied and worn by the patient. Any compression
stocking used should be routinely checked to
ensure continued proper fit and application, in
addition to assessing the condition of the skin.
• Where appropriate, patients should be instructed
in the proper use of the system, the purpose of
therapy and that any problems should be reported
to the nursing staff.
• For surgical patients, the system should be
applied to the patient preoperatively, prior to the
induction of anaesthesia.
• The system should be used continuously for no
less than 72 hours post-operatively or until the
patient becomes fully ambulatory.
• If the garment cannot be applied to the operative
limb during surgery, it may be applied to the limb
once the patient reaches the recovery unit.

If the pump is switched on and one or more
garments are connected to the pump, but therapy
is not started within 15 minutes, an alarm will
occur. If no action is taken to start therapy or
silence the alarm, then 15 minutes after the alarm
starts, the pump will go into an “Off” state (refer
to “Troubleshooting” on page 22).
It is recommended that the following checks are
carried out at the start of, and throughout, the
therapy:
• Check the LCD screen icons to confirm that the
correct type of garment(s) have been connected.
• During garment inflation, check the LCD screen to
confirm that there are no fault indicators displayed
and that the correct pressure is being supplied.
The default target inflation pressures for the
different garments are:
• Foot garment: 130 mmHg.
• Uniform calf and calf & thigh garments:
40 mmHg.
• Sequential calf and calf & thigh garments:
45 mmHg.
• Check that there are no kinks in the tubeset.
• Check that the tubeset and connectors do not
cause the patient any discomfort.
• Regularly check that the garments remain
correctly fitted to the patient.
The pump will inflate and deflate each garment in
turn, as follows, starting with the garment connected
to tubeset connector 1. The garment pressure is
displayed in the top left side of the screen. The
Patient Run Hours are displayed in the bottom right
of the screen.
The following example shows two foot garments
fitted to the pump.
1.Both garments are initially deflated, and the
garment icons are shown as outlines.
2.Foot garment 1 is inflated to the target pressure,
with an inflate time of 3 seconds and a deflate
14
Page 21
time of 27 seconds.The foot garment icon is
black while it is inflated.
3.The foot garment is deflated to zero. Both
garment icons are outlines.
4.Foot garment 2 is then inflated to the target
pressure, with an inflate time of 3 seconds and a
deflate time of 27 seconds. The foot garment
icon is black while it is inflated.
5.The foot garment is deflated to zero. Both
garment icons are outlines.
6.This cycle of alternate garment inflations repeats
from step 2 (above) until the therapy is stopped.
If calf (or calf & thigh) garments are attached to the
pump, then each of these garments is inflated to the
target pressure, with an inflate time of 12 seconds
and a deflate time of 48 seconds.
If a foot garment and a calf (or calf & thigh) garment
are attached to the pump, then since the inflate and
hold times for a foot garment are shorter than for a
calf (or calf & thigh) garment, there is a modified
inflation sequence: the foot garment is always
15
Page 22
inflated twice in succession and then the calf
(or calf & thigh) garment is inflated, as follows.
1.Inflate the foot garment.
2.Deflate the foot garment.
3.Repeat the inflation of the foot garment.
4.Deflate the foot garment.
5.Inflate the calf (or calf & thigh) garment.
6.Deflate the calf (or calf & thigh) garment.
7.This cycle of garment inflations repeats from
step 1 until the therapy is stopped.

5.Cleaning and Disinfection
The following processes are recommended, but should be adapted to comply
with the local or national guidelines (Decontamination of Medical Devices)
which may apply within the healthcare facility or the country of use. If you are
uncertain, you should seek advice from your local infection control specialist.
The system should be routinely decontaminated between patients and at
regular intervals while in use; as is good practice for all reusable medical
devices
Remove the electrical supply to the pump by disconnecting the mains
power cable from the mains power supply before cleaning.
Protective clothing should always be worn when carrying out
decontamination procedures.
Do not use Phenol-based solutions or abrasive compounds or pads
during the decontamination process as these will damage the surface
coating.
.
WARNING
Caution
Avoid immersing electrical parts in water during the cleaning process.
Do not spray cleaning solutions directly onto the pump.
Do not immerse the tubeset in water.
Garments are single patient use and hence cannot be cleaned or reused.
To Clean
Clean all exposed surfaces and remove any organic debris by wiping with a
cloth moistened with a simple (neutral) detergent and water.
Do not allow water or cleaning solutions to collect on the surface of the pump.
Do not use anything abrasive to clean the LCD window on the pump.
Chemical Disinfection
Arjo recommends a chlorine-releasing agent, such as sodium hypochlorite, at a
strength of 1,000ppm available chlorine (this may vary from 250ppm to
10,000ppm depending on local policy and contamination status).
Wipe all cleaned surfaces with the solution, then wipe using a cloth moistened
with water and dry thoroughly.
Alcohol based disinfectants (strength 70%) may be used as an alternative.
Make sure the product is dry before storage.
If an alternative disinfectant is selected from the wide variety available, we
recommend that suitability for use is confirmed with the chemical supplier prior
to use.

7.Troubleshooting
General
On detection of a fault condition, the pump provides a visual-only warning
followed by an audible and visual alarm if the fault is not cleared.
Warning Conditions
The visual-only warning is a fault icon on the LCD screen. The LED indicators
remain unchanged and there is no audible alarm.
The warning can be cleared by either:
• Rectifying the fault on the system, or
• Pressing the Middle Control button to put the pump into Standby.
Alarm Conditions
If the fault is not cleared then the warning is replaced by an audible and visual
alarm, which consists of:
• A fault icon on the LCD screen.
• The LED indicators on the front and underside of the pump change to yellow.
• An audible alarm will sound.
• All the alarm conditions are low priority.
The alarm can be cleared by either:
• Rectifying the fault on the system, or
• Pressing the Middle Control button to put the pump into Standby.
For simplicity, the following screens (except Battery Low, Hardware Fail and
High Temperature) show a fault detected on garment 1; similar fault messages
are displayed if the fault is detected on garment 2 (or both garments).
If the trouble shooting procedures do not return the system to normal
performance, stop using the system immediately and call the service engineer.
Service Manual
Where reference is made in the following Troubleshooting table to the Flowtron
ACS900 Service Manual, this is part number SER0026 and is available from
your local Arjo sales office.
