1. Description and Operating Principle
Flowtron Excel is a non-invasive prophylactic system
for reducing the incidence of deep vein thrombosis
(DVT). The application of intermittent pneumatic
compression has two effects:
1. Augments venous blood flow velocity, thereby
2. Enhances fibrinolytic activity to reduce the risk
of early clot formation.
The Flowtron Excel system consists of a pump and a
pair of calf or thigh length, single patient use garments.
The pump provides intermittent cycles of compressed
air which alternately inflate the single-chambered air
garments. The compression applied on the extremity
augments venous blood flow velocity and stimulates
The pump operates on a 60-second automatically timed
cycle consisting of approximately 12 seconds of
inflation followed by approximately 48 seconds of
The Flowtron Excel system may be used on patients at
risk of developing deep vein thrombosis and in
conjunction with systemic interventions
(e.g. anticoagulation drugs) for the high risk patient.

2. Cautions and Contraindications
1. Proper application and connection to the pump is
2. Garments should be removed if the patient
experiences tingling, numbness or pain.
3. Interruption of external pneumatic compression
for a substantial length of time is discouraged.
Flowtron Excel should NOT be used in the following
1. Severe arteriosclerosis or other ischemic vascular
2. Known or suspected acute deep vein thrombosis.
3. Severe congestive cardiac failure.
4. Any local condition in which garments would
interfere, for example:
Untreated, infected leg wounds
Recent skin graft
3. System Set Up
1. Check that the power switch on the pump is
OFF. Remove the garments from the packaging
2. Place the back of the patient’s leg in the center
section of the garment with the connector tubing
pointing towards the foot.
3. Starting with the side that does not have the
Velcro® tabs, wrap securely against the leg.
While holding the garment snugly against the leg,
wrap the taps over the top. Ensure that the
garments are fitted snugly and are not ‘wrinkled’
or ‘tucked’. The connector tubing should be
pointing towards the patient’s heel.
4. Snap-lock the garment connector to the tubing
assembly. Ensure that a sharp ‘click’ is heard.
Pull lightly to confirm proper connection.
5. To disconnect the garments from the tubing,
press the snap-lock connector and pull apart.
If garments are not applied snugly, a
pump alarm may result. To
correct the alarm, simply rewrap the garment snugly.
To Use Only
To use only one garment, connect a single tube to
either connector. The snap-lock connectors on the
pump are self-sealing and, unlike other systems, DO
NOT require the unused garment to be attached.
to prevent the alarm
Press the Single Leg button
system incorrectly indicating a fault. The system
responds with a ‘beep’ and the LED on the button
illuminates. If the Single Leg button is pressed by
mistake with two garments connected, the system will
reset itself to normal after two cycles.

Before using the Flowtron Excel System on the patient,
The pump has been set at 40 mmHg
(or the pressure prescribed by the physician).
Garments have been applied to patient’s legs
correctly, snugly and without wrinkles.
There are no kinks in the tubing.
The pump is connected to an electrical outlet.
All tubing connections are secure.
Turn the power switch ON which will illuminate green.
The pump performs a two-second self test cycle where
the display, LED’s and alarm are tested. The
compressor then proceeds directly to the inflation
The garments will inflate alternately. The first garment
inflates for approximately 12 seconds and is deflated
for approximately 48 seconds.
The second garment inflates 30 seconds after the
inflation of the first garment and follows the same
Verify that the display is indicating the desired output
pressure. Refer to section 4 - Pressure Adjustment for
specific pressure setting instructions.
4. Pressure Adjustment
The pressure control mechanism is located on the front
of the pump and ranges from 30-60mmHg. The
pressure exerted by the garments on the leg can be
adjusted by turning this knob. Turning the knob
clockwise increases the pressure; counterclockwise
decreases the pressure.
The recommended pressure setting is 40 mmHg, or the pressure
prescribed by the physician.
The Flowtron Excel pressure monitoring system is
independent of the pressure control and delivery
system, providing added reliability and safety. The
digital display indicates the actual pressure that is
delivered to the garments, and furnishes immediate
and continuous feedback regarding pump
The pressure display is used for the following
After turning the pump on, check that the pressure
display is showing the desired output pressure when
the garments are inflated. Visually recheck the display
at regular intervals.
Rotate the pressure control knob during the active
inflation period until the required pressure is
For more stable readings over the total inflation period, disconnect
the garments from the pump and rotate the pressure control knob until
the required pressure is displayed. Reconnect the garments.
To confirm the calibration accuracy of the pressure
control and display, perform the following check each
time the pump is turned on.
During normal operation when the display reads
the pointer on the pressure control knob should be
located somewhere within the 40 mmHg arc on the
front panel. If the pointer falls outside of this arc, the
pump should not be used and referred to service for
The Flowtron Excel system features an audible and
visual alarm.If a problem occurs, the system will sense
the fault and briefly flash a message on the display.
If the same fault continues for successive inflations, the
audible alarm will sound and a flashing message will
remain on the display until corrective action is
The exception to this is an
fault which will alarm

In the unlikely event of a display electronics failure,
the red LED on the top panel will rapidly flash
(approximately four times a second). Do not use the
pump : refer to service.
After a fault has been corrected, the alarm can be
cancelled by two methods:
1. Switch the pump off, then on again, using the
2. Allow the pump to run until it senses a normal
inflation; it will then reset itself.
To confirm that the fault has corrected, watch the
display for about one minute. If everything is normal,
there will be no
message flashing during
If the system fails to operate when plugged in and
switched on, the fuse on the underside of the pump
should be checked. To do this, disconnect the pump
from the main power supply and remove fuse holder
cap using a suitable screwdriver.
To protect against fire hazard, replace blown fuse with identical
type and rating - F500mA. If the fuse blows again, refer the
pump for service.
6. Cleaning Instructions
The outside pump casing is made from ABS plastic
and should be cleaned using a soft cloth dampened
with a mild detergent. Hypocarbonate and phenolic
based cleaning solutions should NEVER be used as
they cause this plastic to deteriorate.
This can be followed by wiping down with a sodium
hypochlorite or sodium chloroisocyanurate (NaDCC)
solution to a dilution of 1000ppm.
Do NOT spray any disinfectant or detergent directly onto the
pump. The pump cannot be sterilised
The garments are single patient use and hence cannot
be cleaned or reused.
