1. Introduction About this Manual

This manual is your introduction to the Flowtron system. Use it to initially set up the system and keep it as a reference for day-to-day routines and as a guide to maintenance.

About Flowtron

The Flowtron system is a non-invasive external intermittent pneumatic compression system for reducing the incidence of Deep Vein Thrombosis (DVT). The application of external pneumatic compression has two effects: • Augments venous blood flow velocity, thereby reducing stasis. • Enhances fibrinolytic activity to reduce the risk of early clot formation. The system comprises a pump that can be used in conjunction with an extensive range of ArjoHuntleigh inflatable garments, including foot, calf and calf & thigh versions. The pump automatically adjusts to the correct therapy profile depending upon which garment type (foot, calf or calf & thigh) 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 pack, which is a secondary power source to back up the pump in the event of failure or disconnection (accidentally or deliberately) from the mains power supply. The Flowtron system is intended for use ONLY in Professional Healthcare Facilities (e.g. hospitals or physicians’ offices).

2. Clinical Applications Indications

The primary application of the Flowtron system is for the prevention of Deep Vein Thrombosis (DVT). Depending on the garment type used, other clinical applications are also appropriate. The FG 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

The Flowtron system should NOT be used in the following conditions: 1. Where an increase of fluid to the heart may be detrimental. 2. Severe congestive cardiac failure. 3. Known or suspected acute deep vein thrombosis, thrombophlebitis or pulmonary embolism. 4. On untreated, infected legs.  If you are unsure of any contraindications, refer to the patient’s physician before using the Flowtron system.

Cautions

1. 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. Additional care should be taken when placing the garments on any deformed leg or foot, or on legs with significant oedema. 3. Garments should be removed immediately if the patient experiences tingling, numbness, or pain, and the physician notified. 4. When used for DVT prevention, continuous external pneumatic compression is recommended until the patient is fully ambulatory. Uninterrupted use of the Flowtron system is encouraged.

5. The Flowtron 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 • In line with good clinical practice, garments should be removed regularly to inspect the skin. Recommendations • 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. DVT Prophylaxis • The Flowtron system should be applied to the patient pre-operatively, 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. • In the non-surgical patient, the system should be initiated immediately the risk of DVT formation is identified.

The “No Garments” Standby screen is then displayed: Attach garments

Battery Indication

Options

There are two “leg” icons with no garments attached and the text “Attach garments” at the top of the screen; this indicates that no garments are currently connected to either tubeset.  There is no text above the Start/Stop button until at least one garment is connected to a tubeset. Apply the prescribed ArjoHuntleigh garment(s) to the patient by carefully following the instructions included in the garment packaging. Connect the garment(s) to the pump by pushing the garment connector firmly into the pump tubeset connector until it “clicks”. The pump LCD screen will show which garments are connected to each tubeset connector: the garment connector with the blue push button is “1” and the one with the orange push button is “2”. If any pump options (Audio Alarm Volume, Patient Hours Meter or Language) need to be changed, they must be changed before the patient therapy is started. Refer to “Changing Options” on page 14.

Make sure the garment(s) are fitted correctly to the patient and the pump. Make sure any pump options have been changed if necessary.  If the pump is to be positioned under a bed, make sure it is placed horizontally (with the bed-hooks underneath) to prevent damage to the pump. While the pump is in Standby, the LEDs on the front case remain extinguished. Press the button below “Start” to start the therapy. The LEDs on the front case change to static green. 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 the correct pressure is being applied and that there are no fault messages displayed. The inflation pressures for the different garments are: • Foot Garment: 130 mmHg. • Calf and Calf & Thigh Garments: 40 mmHg.  Initial inflation cycles (up to 10) may not show the correct inflation pressure. This is to be expected. 10

• Check that there are no kinks in the pump tubesets. • Check that the pump tubesets 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 garment 1:  The following example shows two foot garments fitted to the pump. 1. Both garments are initially deflated. The garment pressure is displayed on the left side of the screen. If the Patient Hours Meter is selected in the “Options” menu (refer to “Changing Options” on page 14), the total elapsed time (in hours) is shown in the bottom right of the screen:

2h

Patient Hours Meter

2. Foot garment 1 is inflated to 130 mmHg, with a ramp up and hold time of 3 seconds. The foot garment indicator is black while it is inflated:

Stop

2h

3. The foot garment is deflated to zero. Both garment indicators are grey:

2h

4. Foot garment 2 is then inflated to 130 mmHg, with a ramp up and hold time of 3 seconds. The foot garment indicator is black while it is inflated:

2h

5. The foot garment is deflated to zero. Both garment indicators are grey:

2h

6. This cycle of alternate garment inflations repeats from step 2 (above) until the therapy is stopped. If one or two calf (or calf & thigh) garments are attached to the pump, then each garment is inflated to 40 mmHg, with a ramp up and hold time of 12 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 inflated twice in succession and then the calf (or calf and thigh) garment is inflated, as follows.  The first garment to be inflated is always garment 1. 1. Inflate the foot garment to 130 mmHg. 2. Deflate the foot garment. 3. Repeat the inflation of the foot garment to 130 mmHg. 4. Deflate the foot garment. 5. Inflate the calf (or calf & thigh) garment to 40 mmHg. 6. Deflate the calf (or calf & thigh) garment. 7. This cycle of garment inflations repeats from step 1 (above) until the therapy is stopped.

Stopping Therapy

To stop the therapy and put the pump into Standby, press and hold the Start/Stop button for approximately 2 seconds until the Standby screen is displayed (refer to “Standby Screens” on page 9) and then release it. The LED indicator by the On/Off button changes to amber and the LEDs on the front case are extinguished. If the pump stays in Standby, then: 1. After 5 minutes the LCD display backlight is dimmed. 2. After a further 15 minutes (20 minutes total) the pump automatically switches off.  The LED indicator will remain amber if the pump is connected to the mains power and extinguished if the mains power is disconnected.

Switching Off the Pump

1. Make sure the therapy is stopped and the pump is in Standby (refer to “Stopping Therapy” on page 13). 2. Press and hold the On/Off button for approximately 2 seconds until the LCD screen goes blank and then release it.  The LED indicator will remain amber if the pump is connected to the mains power and extinguished if the mains power is disconnected.

Alarms

On detection of a fault condition, the Flowtron pump provides a visual-only warning followed by an audible and visual alarm if the fault is not cleared. 1. The visual-only warning is a fault message on the LCD screen. The LED indications remain unchanged and there is no audible alarm. 2. If the fault is not cleared then the warning is replaced by an audible and visual alarm, which consists of: • A fault message on the LCD screen. • The LED indicators on the front of the pump change to red and start flashing. • An audible alarm will sound which increases in pitch and intensity if the alarm is ignored. The warning and alarm can be cleared by either: • Checking and rectifying the fault on the system, or • Pressing the button below “Stop” to put the pump into Standby. Refer to Section 7, Page 20 “Troubleshooting” for the alarms, their possible causes and their remedies.
