1.1 General information
Essential nursing care is pivotal in pressure ulcer prevention.
The Invacare Viscomixt®mattress will positively contribute to the
outcome of a pressure ulcer prevention care plan.
Education, clinical judgement and action based planning based on vulne-
rability are fundamental factors in prevention of pressure ulcers.
A range of assessment scales can be used as a formal method of
assessing risk from pressure ulcer development, and should be used in
conjunction with an informal assessment (informed nursing judge-
ment). Informal assessment is considered to be of greater importance
and clinical value.
Please heed all the notes, particularly the safety information, and act
accordingly.
Should you require more information on the Invacare Viscomixt®
mattress please refer to the Invacare Mattress Brochure and
contact details on the back page of this User Manual.

1.5 Intended use
This pressure redistribution mattress is intended to be used in con-
junction with an appropriately sized bed frame, as part of an overall
pressure ulcer prevention program of care.
This product has been designed to deliver effective pressure reduction
to users, when the product is in normal use which is defined by
Invacare Ltd as when the support surface is covered with a cotton,
cotton combination or linen bed sheet, and any one of these would be
the only item deployed between the support surface and the user.

vided they are used in strict accordance with the intended use as set
out in this document and all maintenance and service requirements
are met. The estimated life expectancy can be exceeded if the product
is carefully used and properly maintained, and provided technical and
scientific advances do not result in technical limitations. The life expec-
tancy can also be considerably reduced by extreme or incorrect usage.
The fact that we estimate a life expectancy for these products does
not constitute an additional warranty.

2 Safety
2.1 Safety information
WARNING
▸Do not use this product or any available optional equipment
without first completely reading and understanding these
instructions and any additional instructional material such as
user manuals, service manuals or instruction sheets supplied
with this product or optional equipment. Invacare product
manuals are available at www.invacare.co.uk or your local
dealer. If you are unable to understand the warnings, cau-
tions or instructions, please contact a healthcare professio-
nal, dealer or technical personnel before attempting to use
this equipment – otherwise, injury or damage may occur.
WARNING
Invacare products are specifically designed and manufactured
for use in conjunction with Invacare accessories.
Accessories designed by other manufacturers have not been
tested by Invacare and are not recommended for use with
Invacare products.
The introduction of certain third party products between
the mattress surface and the user may reduce or impede the
clinical effectiveness of this product.
’Third party products’ may include, but are not limited to
items including under blankets, plastic sheets and sheepskins,
etc. Heated over blankets must only be used in consultation
with a suitably qualified healthcare professional, as an increase
in temperature can increase the risk of developing pressure
ulcers.
WARNING
Bed sheets must be loosely fitted, with creases smoothed out.
Care must always be taken to ensure that the support surface
in contact with the user is kept free from crumbs and other
food debris, and that drip cables, stents, and other foreign
objects do not become entrapped between the user and the
pressure reducing surface of the mattress, as this may result
in the development of pressure ulcers.
!IMPORTANT
The information contained in this document is subject to
change without notice.
▸Check all parts for shipping damage and test before using.
▸In case of damage, do not use.
▸Contact Invacare/Carrier for further instructions.

3.1 Product description
The Invacare Viscomixt®mattress offers exceptional pressure reducing
qualities, specific to the individual’s needs. By promoting even weight
distribution, it reduces tissue pressure at potentially vulnerable areas.
The water-resistant cover provides a vapour-permeable, multi stretch
surface, to promote patient comfort and to maximise the effectiveness
of the foam core.

4 Usage
4.1 Safety information
▸Remove all packaging before use.
▸Place the Invacare Viscomixt®Mattress directly on the frame of the
bed.
WARNING
It is very important for the patient to reposition themselves,
or to be repositioned, on a regular basis. This must be based
on the clinical judgement of a qualified healthcare professi-
onal. This relieves pressure which helps prevent both tissue
compression and potential ulcer formation.
▸Always consult a qualified healthcare professional before
using the Product.
▸Monitor the patient frequently.
CAUTION
The orientation of use of the mattress is indicated on the side
of the mattress on the sewn label.
▸Make sure that the distance between the surface of the
mattress and the top of the side rail is at least 220 mm.
!IMPORTANT
Medical equipment including infusion pumps and monitors
should be attached to appropriate bed accessories. In do-
mestic settings common causes of damage include cigarette
burns and the claws of pets that puncture covers, allowing
fluid ingress and staining.
!IMPORTANT
▸To prevent accidental cover damage, do not place hypo-
dermic needles, venflons, scalpels or other similarly sharp
objects onto the mattress. Ensure that all venflons are taped
down correctly with no sharp edges exposed.
▸When using bridging boards or other patient transfer aids,
care should be taken not to damage the mattress cover.
All transfer aids should be checked for any sharp edges or
burrs before use as these can damage the mattress cover.
▸Make sure that the mattresses are not jammed or damaged
by sharp edges when used on beds with an adjustable frame.
▸When using the mattress on a profiling bed ensure that the
knee break is used before the backrest.
5 Transport

6 Maintenance
6.1 Inspection

de fluid ingress, stains, rips or damage) after the release of each patient
or on a minimum monthly basis (depending on which occurs first) by a
suitably qualified and competent person.
Check mattresses
▸Unzip the cover completely.
▸Check for any staining on the white underside of the cover.
▸Check for any staining on the interior foam.

procedure.
6.2 Cleaning and care
!IMPORTANT

compatible with one another and must protect the materials
they are used to clean. For further information on decon-
tamination in Healthcare Environments, please refer to ‘The
National Institute for Clinical Excellence’ guidelines on Infec-
tion Control www.nice.org.uk/CG002 and your local infection
control policy.
Cleaning covers
(Removal of contaminants such as dust and organic matter)
▸Remove all covers for laundering.
▸Launder the covers at the recommended maximum temperature of
90 °C using a diluted detergent solution.
(Instructions on label).
!IMPORTANT
Washing at higher temperatures may cause shrinkage.
Drying covers
▸Hang mattress covers from a line or bar and drip dry in a clean
indoor environment.
or
▸Tumble dry on a low heat setting.
!IMPORTANT
▸Tumble dry setting must not exceed 40 °C.

Disinfecting covers
(Reducing the number of microorganisms)
Please contact your hygiene specialist in the event of contamination.
!IMPORTANT
Ensure that any residual detergent has been removed prior to
disinfection.
Light soilage
▸Wipe down the cover with a 0.1% Chlorine Solution (1,000 ppm).
▸Rinse the cover with clean water using a single use nonabrasive
cloth.
▸Dry the cover thoroughly.
Heavy soilage
Where the mattress is badly soiled, we recommend cleaning with a
dilute cleaning solution at 90 °C in the washing machine.

Viscomixt® MattressAfter-use
9
iLarge spillages of blood should be absorbed and removed with
paper towels first.
▸Clean up all spillages of bodily fluids i.e. blood, urine, faeces, sputum,
wound exudater and all other bodily secretions as soon as possible
using a 1% Chlorine Solution (10,000 ppm).
▸Rinse the cover with clean water using a single use nonabrasive
cloth, and dry thoroughly.
!IMPORTANT
Polyurethane coated fabrics can absorb liquids for short
periods causing a temporary change to the polyurethane
characteristics. The mattress cover swells temporarily and
is more vulnerable to physical damage for a period after it is
completely surface dried, by which time it will revert to its
previous state.
▸Dry the cover thoroughly.
WARNING
▸Remove contaminated foams from use.
CAUTION
▸Keep clear of open heat sources.
!IMPORTANT
▸Do not use phenols, alcohols, bleaches, or other abrasive
materials.

correctly into the corners of the cover. Ensure that the
visco elastic side of the foam is facing uppermost when
packed into its cover.
