SECTION 2 - INTRODUCTION
2.1 GENERAL
The VIACLIN Alternating Pressure Mattress Overlay is designed for use whenever patients have some mobility problems
and/or who are vulnerable to pressure ulcer development and/or who have existing tissue damage. It gives gentle, dynamic
support to bedridden and immobile people in recumbent, supine and knee-break postures, providing alternatively support
then pressure relief to each part of the underside of the patient.
The bed can be repositioned whilst the Mattress Overlay is still inflated.
The system is suitable for use in hospitals, nursing homes and in the community.
2.2 SYSTEM DESCRIPTION
The system consists of a power unit and a mattress overlay. Audio and visual alarms activate if a fault condition exists for
more than three minutes (compressor failure, overlay or airpipe failure). An audio alarm sounds if the mains supply fails
(disconnected or switched off). These alarms alerts medical staff to the malfunction.
The specially constructed overlay comprises a series of pairs of transverse cells, which are inflated and deflated alternately.
Air to inflate the overlay is provided by an electronically controlled power unit. The air pressure in the overlay is
continuously monitored, and the system is completely self-regulating. The overlay is connected to the power unit by
means of an airpipe which features quick release connections at the power unit end, for convenience and rapid deflation,
to allow cardiac resuscitation procedures. Operator controls are purposely kept to a minimum.
The overlay is positioned on top of the normal bed mattress.

SECTION 3 - SETTING UP/OPERATION
3.1 SETTING UP
CAUTION: Use only on top of the existing bed mattress.
Remove the bedding from the bed.
Ensure there are no sharp objects to damage the Overlay. Place the Overlay on top of the bed mattress with the
umbilical at the foot end of the bed. Tuck the two end flaps under the bed mattress.
Secure the Overlay straps to the mattress. Do not secure to the bed frame (only secure Overlay straps loosely to the
moving parts of the bed frame, (if applicable).

LFT5508 3.2Issue 3
VIACLIN MODEL 2502 Oct 02
Hang the power unit on the bed or place on the floor.
Connect the three airpipe connectors on to the power unit connectors. Plug the power unit into a suitable mains
socket and switch on.
The system will take approximately 20 minutes to reach full inflation pressure, at which time the green NORMAL light
will come on and the amber light will extinguish. During this start up phase the red FAULT light may come on and the
audible alarm sound, if this occurs turn the power unit off and back on again to reset the alarm.

LFT5508 3.3Issue 3
VIACLIN MODEL 2502 Oct 02
Once inflated, check the securing straps and tighten if required. For maximum benefit, use only one sheet loosely
placed over the mattress. If the sheet is tucked in ensure that it is left loose over the mattress to avoid hammocking.
Once a patient is placed on the mattress the system will adjust automatically to the patient characteristics
(weight/position) to provide optimum clinical benefit for each patient. The mattress may feel firm at first until it has
adjusted to the individual. Allow approximately 15 minutes for this automatic adjustment to be completed.
If the mattress does not perform as described above, please refer to Section F of this guide ‘Alarms and Fault Finding’.
3.2 PROFILING AND KNEE-BREAKING
The system may be used while the bed is in the profiled or knee-break position:
1. With the bed in its present position, loosen or release the Overlay securing straps.
2. Change the bed to the required position (profile or knee-break).
3. Re-secure the securing straps.
NOTE: Straps must be attached to moving parts of the bed frame to avoid jamming the bed mechanism or stretching
the overlay.

3.3 MOVING THE BED AND POWER CUTS
CAUTION: The patient will not receive the benefit of the VIACLIN system while it is disconnected
and the power unit is switched off. Therefore the system should be reconnected as
soon as possible once the bed has been moved to its new position.
If you need to move the bed with the Mattress Overlay still inflated or in the event of a major mains power failure,
carry out the following procedure:
1. OVERLAY
aDisconnect the two red airpipes from the power unit and quickly connect together.
bDisconnect the black airpipe from the power unit.
2. POWER UNIT
aSwitch off and reset the power-down alarm. Disconnect from the mains.
b. The overlay will remain inflated for over 24 hours. The bed can now be moved.
