WARNING

WARNING!
Only to be used for its intended purpose as described in this manual. Never attempt to repair the system yourself. DO NOT use parts or individual components of other systems or products other than those described in this manual, or other documentation from OSKA, to repair this mattress.

Avoid using multiple V-Guard covers simultaneously.

DO NOT USE in close proximity with fire sources/hot surfaces. These include fire, burning cigarettes or hot lamps. This mattress has undergone fire testing but may still become damaged if contact with fire sources occurs. Position the mattress correctly to prevent it from becoming trapped and damaged.

NOTE:
Bed rails can trap the mattress and cause damage.

Confirm that the bed frame is appropriate for use with the mattress and that the length and width of the mattress are appropriate for the frame. Avoid the risk of suffocation from the mattress cover by positioning the patient correctly. DO NOT puncture the mattress or mattress cover with needles or sharp instruments. This may result in the loss of integrity of the mattress cover. Inspect the covers and zipper area for signs of damage, puncture, or wear that could result in fluid pass-through.

Handles included on the long side of the mattress cover should only be used for lifting and moving the mattress itself.

CAUTION!
A notice to the user and/or patient that any serious incident that has occurred in relation to the device should be reported to the manufacturer and competent authority of the member state in which the user and/or patient is established.

About your mattress

The system
This mattress provides high user comfort without the need for an external pump or electricity by combining foam and air. Included in the system design is a unique Heel Zone that is designed to further reduce pressure for the sensitive heel area. Also included is the Offloader feature, designed to create a zone of zero pressure. In order to maintain low surface pressure the special valve technology allows the internal air reservoir inside the mattress to be distributed amongst the cells by patient weight and movement.

Cover
The Series4 comes with a V-Guard cover which provides an impenetrable barrier to viruses and bacteria. The cover has welded seams that are ingress-proof, minimizing any risk of harboring viruses or bacteria and transmitting infections. The cover includes a fire evacuation base which means handles can be easily accessed in case of emergency and used for moving and transporting.

An additional inner cover protects the foam and cells.

Recommendations
OSKA Series4 self-adjusting replacement pressure system is recommended to be used as an aid in the prevention and treatment of pressure ulcers up to and including category 2. The Offloader feature can be used as an aid to create a zone of zero pressure to help prevent and treat pressure ulcers up to and including category 4.

Capacity
OSKA Series4 is recommended for patient weight up to 230kg. Heavier patients are better accommodated with a more appropriate OSKA pressure system. The fire evacuation base included within the cover can be used for patients weighing up to 130kg. You must not lift the mattress whilst a patient is lying on it or use it to transport a patient unless in an evacuation.

Offloader

The mattress is made from 2 layers of foam. The top layer is able to be manipulated and folded under any of the sides to alleviate pressure from parts of the body and create an area of zero pressure. Zero pressure can be used as an aid to help prevent and treat pressure ulcers up to and including category 4.

How to set up your mattress

Unpacking the mattress
Please ensure the box is not damaged upon arrival. Avoid using a knife when opening the box and any other protective material as this could damage the mattress and/or cover.
Place the Series4 onto the bed frame and adjust the cover if needed. The mattress has a black side that should be down on the bed frame, and a blue fabric side that should face up towards the patient. Confirm that the bed frame is appropriate for use with the mattress and that the length and width of the mattress are appropriate for the frame. Place directly on a healthcare bedframe only, never on top of another mattress.

Leave for a few minutes before using.

Hand check
The hand check should be conducted regularly to check the mattress is functioning correctly. With the cover open, using a vertical hand, insert your hand between the air and cells directly underneath the patient’s sacrum. The correct clearance between the mattress base and the patient is 2-3 fingers. Check the cells and tubing if this is not the case. If the problem persists please contact OSKA.

Evacuation base

The Series 4 comes with evacuation straps within it‘s base. It is very important that the safety equipment, as well as the evacuation procedures, are well-planned and known in advance. These covers can significantly help you be prepared in the case of a fire or other emergency when a less mobile patient will need to be evacuated. Handles appear on all 4 sides of the cover and the velcro fire evacuation straps are housed securely in pockets on the 2 longer sides with their ends sticking out for easy access. These straps are used in the case of an emergency to secure the patient to the mattress before transporting them to safe area.

WARNING!
It is imperative that anyone performing an evacuation must have acquired the necessary training. Before commencing any evacuation always check the equipment, cover and mattress to ensure the evacuation can be carried out safely.

Ensuring the mattress is safe to use for evacuation is the user’s responsibility.

Evacuation instructions

• Let the patient know what is about to happen
• Lower and lock the bed in position
• Disconnect the tubes from the pump
• Pull the velcro evacuation straps out of the base and fasten
• Using the outer handles at the foot end of the mattress, turn it outwards from the bed
• Carefully drag the mattress and patient down on to the floor
• Use the outer handles at the foot end of the mattress. The working position should be a little bit leaning back

Down the stairs

• Walking backward, continue until the main part of the mattress slides pass the top stair
• Turn your back towards the patient and look in the direction you are moving
• Holding one hand on the stair rail and the other hand on the middle handle of the mattress, begin to pull
• Walk down the stairs maintaining speed, without running, is important

Training/practice
To bear in mind when training. Pulling down from the bed:

• Make sure the patient in the bed is not at the very top of the mattress. If they are, it increases the risk of hitting their head on the bed when pulling down

Pulling on the stairs:

• Practice this technique by pulling an empty mattress down the stairs
• When training with a person on the mattress, fasten a string or rope onto the handles at the head end. This enables another person to then walk behind the mattress and help out
• Practicing on the stairs where an evacuation may be necessary is advisable

General:
The purpose of the training is not to carry it out at high speed, but to grasp the correct technique

Training covers:

• When the equipment is used to evacuate, heavy strain is put on the seams and handles. Always check the seams and handles at the end of training. It is advisable to mark any equipment used for training as “Training equipment” and use it only for this purpose

Explanations
Always use the velcro straps when evacuating a patient to prevent the patient sliding/rolling down from the mattress

• Pulling at the foot end reduces the strain on the puller, which means faster and safer evacuation is possible
• Pulling the mattress on the stairs is the hardest part of the evacuation and should therefore be practised carefully
• Keep the patients arms inside the velcro straps. This prevents the user grabbing hold of something out of fear

Cleaning

V-Guard Cleaning and Aftercare guidelines.
OSKA V-Guard technology covers are durable but, as medical devices, they need treating with great care. The surface is vapor permeable so it is waterproof but breathable to reduce sweating of the patient. This outer barrier must not be penetrated. Even the smallest breach of this barrier will cause fluid to penetrate the mattress.

There are specific cleaning and care instructions that need to be strictly adhered to prolong the life of the product.

General directives

1. Abrasive cleaning agents should NOT be used.
2. In addition, due to the range of cleaning chemicals and conditioners being used, customers should ascertain that any fabric performs as expected, without any adverse effect.
3. Some surface wrinkling may result from cleaning procedures. This should have no adverse effect on the fabric’s properties.
4. If customers have their own particular cleaning methods that must be used and that are not covered in this article, they should consult OSKA for further direction and guidance.

Washing and disinfection

1. All polyurethane coatings need to be treated with care when cleaning the surface. Many industrial cleaning agents are extremely harsh on the coating and can cause it to break down.
2. For superficial dirt use a disposable wipe and a warm solution of neutral detergent. Do not use abrasive cleaners.
3. Disinfect in situ using 0.1% sodium hypochlorite solution (1000ppm available chlorine). Wipe off any residue with clean water. V-Guard covers can tolerate 10,000ppm chlorine but using a weaker solution of 1,000 ppm will reduce the risk of a high concentration being left on the surface.
4. The fabrics are able to be washed in warm soap water at up to 95°C.
5. All cleaning agents and disinfectants must be thoroughly rinsed off and the item dried before storage.

Drying

1. Spin and tumble dry on a low setting (not more than 130°C. The fabric surface may wrinkle but this will not impede function). The operator ensures it is removed as soon as all moisture is removed. The fabric must not be left sitting on the heated bowl of the drier when drying is complete.
2. Do not mangle.
3. Do not iron.

Storage

1. Store in a cool dry area.
2. Avoid excessive pressure and always thoroughly dry fabric before re-use or storage. Do not fold away wet or store in damp conditions.
3. Keep away from sharp objects.

Damages and replacement

1. Regularly check the inside of the cover for any signs of leakage
2. If the cover leaks then the waterproof barrier has been broken and a new cover should be purchased from OSKA.

Delamination
Delamination is when the layers within the structure of the mattress cover separate. This can be caused by using incorrect chemicals or too high a concentration of cleaning chemicals on the surface.

How to prevent delamination
OSKA V-guard Technology covers incorporate a special layering system to make them much more resistant to delamination than many other mattress covers. However, to help prevent delamination:

1. Always abide by the cleaning instructions
2. Avoid using chemicals with too high a concentration.
3. Ensure cleaning chemicals are always thoroughly rinsed off before allowing them to dry
4. The V-Guard covers can tolerate up to 10,000ppm chlorine but using a weaker solution of 1,000ppm will reduce the risk of a high concentrate being left on the surface
5. Ensure the covers are thoroughly dry before using or storing the mattress

Strikethrough
Strikethrough occurs when the fibers in the mattress covers start to break down. Small cracks develop, which on inspection, may not be visible. This means fluids and other contaminants can pass through the cover and contaminate the core of the mattress.

How to prevent strikethrough
Covers are most susceptible to strikethrough damage when they are wet. During cleaning, extra care should be taken to avoid abrasion of the surface. OSKA V-Guard

Technology covers incorporate a special layering system to make them much more durable than many other mattress covers. However, to help prevent strikethrough:

1. Always abide by the cleaning instructions
2. Avoid using chemicals with too high a concentration.
3. Ensure cleaning chemicals are always thoroughly rinsed off before allowing to dry
4. The V-Guard covers can tolerate up to 10,000ppm chlorine but using a weaker solution of 1,000ppm will reduce the risk of a high concentrate being left on the surface
5. Ensure the covers are thoroughly dry before using or storing the mattress

General information

Storage
Store the mattress on a flat surface or carefully rolled/folded with the zip closed. Always store at room temperature in a dry area. Make sure the mattress is stored where it will not be exposed to thrusts, hits or other things that can damage it. Avoid direct exposure of sunlight. If the mattress is to be stored for more than 3 months, we recommend it is stored on a flat surface (not folded or rolled up).

Service and repairs
Only spare parts which have been approved by OSKA should be used. Using non- approved spare parts will invalidate the warranty.

You must submit a warranty claim to OSKA before the product is returned. If you have questions regarding warranty and service please contact OSKA.

Warranty

The warranty is based on statutory regulations. The warranty does not apply if the goods supplied by OSKA are processed, handled or modified by other parties without prior consent from OSKA or if these operating instructions are not followed.

For medical devices as understood by the EU – Directive 93/94, whose usage (also operations) is subject to regular service and maintenance, a warranty can be offered only if the service intervals prescribed by OSKA are adhered to. If during inspection it is found that damages are due to wear and tear or are not subject to warranty, then OSKA are empowered to claim the expenses (inspection, transport costs etc) from the client. The use of parts or individual components of other systems or products or combinations thereof are not permissible.

Warranty claims become invalid should any damage result from this kind of conduct and therefore remain the responsibility of the user/owner.
